fix(verfahrensablauf): m/paliad#59 — restore click-to-edit on timeline dates

Per-rule due dates on /tools/verfahrensablauf were rendered as plain
spans with no `frist-date-edit` attrs and no delegated click handler,
so clicking a date did nothing (m's "the timeline dates seem to be fix,
nothing happens when I click on a date"). The wiring existed on
/tools/fristenrechner but had never been mirrored onto the abstract-
browse surface introduced in t-paliad-179.

Fix: lift the inline date editor + delegated click wiring out of
fristenrechner.ts into views/verfahrensablauf-core.ts so both pages
share one implementation:

  - openInlineDateEditor(span, onCommit) — swaps the date span for
    a `<input type=date>`, commits on blur/Enter, cancels on Escape,
    fires `onCommit(ruleCode, newValue)` ("" = revert).
  - wireDateEditClicks(container, onCommit) — idempotent delegated
    click + keyboard handler that resolves `.frist-date-edit
    [data-rule-code]` and opens the editor. Survives innerHTML
    rewrites because the listener lives on the container.

verfahrensablauf.ts now:
  - Owns its own anchorOverrides Map (cleared when proceeding-type
    changes — overrides for one proceeding don't apply to another).
  - Forwards overrides in calculateDeadlines() so downstream rules
    re-anchor on the user's date.
  - Passes `editable: true` to renderColumnsBody + renderTimelineBody.
  - Calls wireDateEditClicks() once on #timeline-container in
    DOMContentLoaded.

fristenrechner.ts shrinks: openInlineDateEditor + the inline click /
keydown blocks are replaced by an `onDateEditCommit` callback handed
to the shared wireDateEditClicks(). No behaviour change there.

Regression test: views/verfahrensablauf-core.test.ts pins the
editable→`data-rule-code` contract on `deadlineCardHtml` so a future
refactor that drops the attrs fails loudly instead of silently
breaking click-to-edit on both pages.

+# Design — "Suggest changes" action on approval flow
+
+**Author:** hertz (inventor)
+**Date:** 2026-05-19
+**Task:** t-paliad-216 (m/paliad in-flight)
+**Branch:** `mai/hertz/inventor-suggest-changes`
+**Status:** DESIGN — open questions await m before any coder shift.
+
+---
+
+## 0. TL;DR
+
+Add a fourth action **"Änderungen vorschlagen"** ("Suggest changes") to the approval flow, alongside Approve / Reject / Revoke. Use case: the approver doesn't want to accept the proposed change as-is, but doesn't want to reject outright — they edit the proposed values into a counter-proposal and submit it back into the same approval flow.
+
+**Mental model (m, 2026-05-19):** suggest-changes is not "ping the requester to fix it" — it's the approver **authoring a counter-proposal** that gets re-injected into the approval flow as a fresh `pending` row. The original requester (now potentially an eligible approver of the counter, since they're no longer the requested_by) sees:
+- the **old row** in their /inbox as `changes_requested` ("Abgelehnt mit Vorschlag" / "Declined with changes") — historical record of their original attempt;
+- the **new row** in /inbox as `pending` — the counter, which they can approve, reject, revoke (n/a, not theirs), or suggest changes back on. Everyone else eligible sees the new row too. 4-Augen still holds: the counter's requested_by (the approver who suggested it) cannot self-approve.
+
+Click flow:
+1. Approver opens an editable modal on the pending row showing the requester's proposed values. Edits any field. Writes a free-text note ("Bitte den Termin um 9:00 statt 8:00, weil der Raum sonst kollidiert").
+2. POST `/api/approval-requests/{id}/suggest-changes` with `{note, counter_payload}`.
+3. Server, in one tx: closes the old row (`changes_requested`, `decision_note=note`), reverts the entity from `pre_image`, then immediately inserts a **new** `pending` approval_requests row authored by the approver with `payload=counter_payload`, re-applies the counter to the entity, marks `pending_request_id` to the new row, emits two events (`*_approval_changes_suggested` + `*_approval_requested`). `previous_request_id` FK links new → old for chain traversal.
+
+The pending audience for the new row is the same as any fresh `Submit*` — the existing notification + visibility plumbing handles it without special-casing.
+
+---
+
+## 0a. m's decisions (2026-05-19)
+
+| # | Header | m picked | Reasoning note (when different from recommendation) |
+|---|---|---|---|
+| Q1 | State machine | **(a) New status `changes_requested`.** | As recommended. |
+| Q2 | Entity state | **(a) Reverts to pre_image, same as Reject.** | As recommended. The counter is then re-applied in the same tx by the new approval row's write-then-approve cycle. |
+| Q3 | Chain depth | **(a) Yes, across chained rows.** | As recommended. |
+| Q4 | Note shape | **Hybrid: approver can edit the proposed values (counter-proposal) AND/OR leave free-text in `decision_note`.** | Differs from (a). Inventor picked free-text-only; m's twist: the suggestion should ALSO carry concrete edits. This adds a `counter_payload jsonb` column on `approval_requests` and turns "suggest-changes" into an action that authors a real counter-proposal, not just a hint. |
+| Q5 | Surface | **(a) /inbox only — v1.** | As recommended. Email + entity-detail badge are Phase 2. |
+| Q6 | Requester actions | **Different model: the counter is a NEW pending approval_request row, not an "edit + resubmit" CTA on the requester side.** | Differs from (a). m's reframing: instead of routing back to the requester to act on, the suggestion IS the next request. Original requester sees the old row as `changes_requested` (status pill "Abgelehnt mit Vorschlag" or similar). Original requester then sees the NEW row in /inbox like any pending — and **may approve it themselves**, because they are no longer the row's requested_by (the suggesting approver is). Everyone else eligible sees it too. Cleaner workflow, removes the "edit-and-resubmit CTA" from the requester role entirely. |
+| Q7 | Notifications | **(b) Notify all eligible approvers + the original requester for the NEW pending row.** | Consistent with Q6. The counter is a fresh `pending` request, so the existing Submit*-notification audience applies. The original requester needs the ping because they're now an eligible approver of the counter — no special-case path. |
+| Q8 | Audit shape | **(a) New event_type `*_approval_changes_suggested` per entity.** | As recommended. The new row also emits a normal `*_approval_requested` event, so the Verlauf chronology naturally captures the chain. |
+
+The decisions above lock the design. §3 has been rewritten to reflect them; §2 (open questions) is retained as the historical record of what was open before the decisions.
+
+---
+
+## 1. Context — what's already in the code (verified 2026-05-19)
+
+- **State machine** in `internal/services/approval_service.go`:
+  - `paliad.approval_requests.status` CHECK is already `('pending', 'approved', 'rejected', 'revoked', 'superseded')` — the `superseded` value is defined as a Go constant `RequestStatusSuperseded` but never written by the live service (reserved).
+  - `paliad.{deadlines,appointments}.approval_status` CHECK is `('approved', 'pending', 'legacy')` — three values only.
+  - Shared kernel `decide(requestID, callerID, finalStatus, note)` powers Approve / Reject / Revoke. Approve invokes `applyApproved`; Reject + Revoke invoke `applyRevert` (restores entity from `pre_image`).
+  - Self-approval blocked at 3 layers: `canApprove` Go gate, `approval_requests_no_self_approval` DB CHECK, deadlock-check excludes requester from pool.
+- **Handlers** in `internal/handlers/approvals.go`:
+  - `POST /api/approval-requests/{id}/approve`
+  - `POST /api/approval-requests/{id}/reject`
+  - `POST /api/approval-requests/{id}/revoke`
+  - `GET  /api/approval-requests/{id}` — single hydrated request
+- **Per-viewer flags** (t-paliad-202, shipped): every row carries `viewer_can_approve` + `viewer_is_requester` resolved server-side so the UI can grey out buttons the server would reject. Server still enforces — the flags are a UX hint.
+- **Frontend**:
+  - `frontend/src/client/inbox.ts` wires three buttons per pending row (approve/reject/revoke). Reject opens `window.prompt()` for the note; approve+revoke don't.
+  - `frontend/src/client/views/shape-list.ts` (row_action="approve") stamps the row with action buttons + diff + `decision_note` display if present.
+- **Audit**: event types `*_approval_requested`, `*_approval_approved`, `*_approval_rejected`, `*_approval_revoked` emitted to `paliad.project_events` (one per entity_type prefix).
+- **Decision note**: `paliad.approval_requests.decision_note text` — a single free-text column, last-write-wins. Already populated on Reject (Approve also accepts an optional note).
+
+---
+
+## 2. Design questions (the open list — see §6 for answered)
+
+Pre-recommendations from inventor. m will pick via AskUserQuestion.
+
+### State machine
+
+**Q1 — Where does "suggest changes" sit on the lifecycle?**
+- **(a) New status `changes_requested` (RECOMMENDED).** The approval_requests row transitions pending → changes_requested. Sibling of approved/rejected/revoked/superseded. The row is terminal in that status; a re-submit creates a fresh row (linked via `previous_request_id`).
+- (b) Reuse `rejected` with `is_revisable=true` flag. Cheap, but conflates two semantically distinct outcomes ("we'll never want this" vs. "tweak X and try again").
+- (c) Auto-revoke the current row, mark the entity for edit, requester creates a new approval row when ready. Reuses existing plumbing — but loses the approver's note as a first-class thing (it'd just be a comment on the project_events row).
+- (d) Other (you'll tell us).
+
+Recommend (a) — keeps the audit lifecycle clear, gives us a clean place to hang the suggestion note, and is the smallest schema change (one new value in a CHECK constraint).
+
+**Q2 — What happens to the entity (deadline/appointment) while in "changes requested"?**
+- **(a) Entity reverts to pre_image — same as Reject (RECOMMENDED).** approval_status flips back to `approved`. The requester edits the entity in the normal flow; saving fires a fresh `Submit*` cycle.
+- (b) Entity stays at `approval_status=pending` carrying the proposed values; requester edits "in place" through a new "amend the pending request" endpoint that mutates the same approval_request row + entity fields.
+- (c) Entity goes to a new `approval_status=draft` (would require a new value on the entity-level CHECK + UI work to handle a third entity state).
+
+Recommend (a) — minimum schema change, reuses every existing path (entity edit, Submit*, applyRevert, project_events emission). The trade-off is one extra approval_requests row per cycle; we link via `previous_request_id` so the chain stays inspectable.
+
+**Q3 — Can the approver suggest changes multiple times (across a chain)?**
+- **(a) Yes, across chained rows (RECOMMENDED).** Each row is terminal after suggest-changes; the requester resubmits → new pending row → approver can suggest changes again. Chain depth unbounded.
+- (b) No — one chance per entity-lifecycle; if the requester comes back, the only options are approve or reject (the suggest-changes button is hidden for the second submission).
+
+Recommend (a) — bounded by the requester's patience, not by the system. Multi-round review is the norm in legal-doc workflows.
+
+**Q4 — Note shape on the suggestion**
+- **(a) Free-text — reuse `decision_note` (RECOMMENDED).** Same column the existing Reject path already populates. Last-write-wins per row (but rows are terminal after suggest-changes, so there's no real "last write").
+- (b) Thread of notes — new `paliad.approval_notes` table, ordered, multi-author. Lets the requester respond inline, the approver clarify, etc.
+- (c) Structured per-field suggestions (`[{"field": "due_date", "current": "...", "suggested": "..."}]`) — a "diff-style" view.
+
+Recommend (a) — matches the existing Reject UX, no new schema. (b) is right if the team wants to discuss; (c) is over-engineered for v1.
+
+### UX
+
+**Q5 — Where does the requester see the suggestion?**
+- **(a) /inbox under `a_role=self_requested` (RECOMMENDED for v1).** Same surface they already use to see rejected. New status pill "Änderungen vorgeschlagen" + the note + a CTA "Bearbeiten und erneut einreichen".
+- (b) A new badge on the entity's detail page (e.g. on the deadline detail page itself).
+- (c) Email + push notification.
+- (d) All of the above.
+
+Recommend (a) for v1. Email reminder is a natural Phase-2 add-on (it'd reuse the existing reminder-mail plumbing). The entity-detail badge is nice but the user is already seeing the row in /inbox.
+
+**Q6 — What action(s) does the requester have on a `changes_requested` row?**
+- **(a) Edit and resubmit (RECOMMENDED).** Primary action. Opens the entity's edit form pre-populated with the original `payload`. Saving fires `Submit*` → new pending request with `previous_request_id` linking back.
+- (b) Withdraw (= dismiss the row from inbox, no DB change). Mostly UI-only — the row is already terminal; "withdraw" would just be a "mark as not-pursuing" toggle.
+- (c) Both.
+
+Recommend (a). The row is already terminal once status=`changes_requested`; the requester either acts on the suggestion (a) or lets the row sit in their inbox history (no action needed). Adding a "dismiss" button is a UI nice-to-have but doesn't change the data model; can defer.
+
+### Notifications
+
+**Q7 — Who gets notified when "suggest changes" fires?**
+- **(a) Just the requester (RECOMMENDED for v1).** Email-reminder path is reused: requester gets a mail "X hat Änderungen vorgeschlagen für …" with the note inline + a link to /inbox.
+- (b) Requester + any other potential approvers (they need to know the request is closed, not pending).
+- (c) Requester + approval-policy-defined watchers (would require a new `approval_policies.watchers` column).
+
+Recommend (a). The request is terminal so other approvers don't need a "this is now your problem" ping — they wouldn't have anything to act on. They see it in /inbox under "Alle sichtbaren" anyway if curious.
+
+### Audit
+
+**Q8 — Audit row shape on `project_events`**
+- **(a) New event_type `*_approval_changes_suggested` per entity (RECOMMENDED).** Parallel to the existing 4 (requested/approved/rejected/revoked). Two new event types: `deadline_approval_changes_suggested`, `appointment_approval_changes_suggested`. Note text goes in metadata.
+- (b) Bundle with the resubmission — single composite event "approved-with-revisions" when the chain eventually approves.
+
+Recommend (a). Each transition gets its own event row — that's how the existing audit chain already works (one event per state change). It also gives the Verlauf timeline a row to render the approver's note.
+
+---
+
+## 3. Implementation sketch (decisions-locked, see §0a)
+
+### 3.1 Migration `103_approval_suggest_changes.up.sql`
+
+```sql
+-- 1. Extend approval_requests.status CHECK to allow 'changes_requested'.
+ALTER TABLE paliad.approval_requests
+    DROP CONSTRAINT IF EXISTS approval_requests_status_check;
+ALTER TABLE paliad.approval_requests
+    ADD  CONSTRAINT approval_requests_status_check
+    CHECK (status IN ('pending', 'approved', 'rejected', 'revoked', 'superseded', 'changes_requested'));
+
+-- 2. Add counter_payload — the approver's edited values, becomes the
+--    `payload` of the NEW pending row spawned in the same tx as the
+--    suggest-changes call. Stored on the OLD (now changes_requested) row
+--    too so the audit chain can show "approver edited X, Y, Z" without
+--    joining to the next row.
+ALTER TABLE paliad.approval_requests
+    ADD COLUMN counter_payload jsonb NULL;
+
+-- 3. Add previous_request_id FK so the new row links back to its origin.
+ALTER TABLE paliad.approval_requests
+    ADD COLUMN previous_request_id uuid NULL
+        REFERENCES paliad.approval_requests(id) ON DELETE SET NULL;
+
+CREATE INDEX approval_requests_previous_idx
+    ON paliad.approval_requests (previous_request_id)
+    WHERE previous_request_id IS NOT NULL;
+```
+
+`.down.sql`: drop the index + columns, restore the original CHECK (would reject existing `changes_requested` rows — that's normal for a breaking-change down).
+
+### 3.2 Service layer
+
+`SuggestChanges` is the only new public method on `ApprovalService`. It runs in **one transaction** and does five things:
+
+```go
+const RequestStatusChangesRequested = "changes_requested"
+
+var ErrSuggestionRequiresChange = errors.New("suggestion_requires_change")
+
+// SuggestChanges closes the pending request as `changes_requested`,
+// reverts the entity, then immediately inserts a new pending
+// approval_request authored by the caller carrying `counterPayload` as
+// its new payload. The new row enters the standard pending flow — anyone
+// eligible (including the original requester) can approve, reject,
+// suggest-changes-again, etc.
+//
+// Authorization: caller satisfies canApprove on the OLD row (same gate
+// as Approve / Reject). For the NEW row, the caller is the requested_by
+// — self-approval is blocked by the standard 3-layer guard. Deadlock
+// check (qualified-approver-exists-other-than-caller) runs on the new
+// row to avoid spawning an unapprovable request.
+//
+// counterPayload must differ from the old row's payload OR a non-empty
+// note must be present. A no-op suggest (same values, no note) is
+// indistinguishable from "I have no opinion" and gets rejected with
+// ErrSuggestionRequiresChange.
+func (s *ApprovalService) SuggestChanges(
+    ctx context.Context,
+    requestID, callerID uuid.UUID,
+    counterPayload []byte,   // jsonb-marshaled
+    note string,
+) (newRequestID *uuid.UUID, err error) {
+    // 1. Begin tx, lock old row, validate status=pending + canApprove.
+    // 2. Validate: counterPayload differs from old payload OR note != "".
+    // 3. Update old row: status='changes_requested', decided_by=callerID,
+    //    decision_note=note, counter_payload=counterPayload.
+    // 4. applyRevert on the entity (uses old row's pre_image).
+    // 5. Deadlock-check on the new row's required_role + projectID,
+    //    excluding callerID.
+    // 6. INSERT new approval_requests row: requested_by=callerID,
+    //    pre_image=<entity-state-as-just-reverted> (= old.pre_image),
+    //    payload=counterPayload, required_role=old.required_role,
+    //    lifecycle_event=old.lifecycle_event, entity_type=old.entity_type,
+    //    entity_id=old.entity_id, status='pending',
+    //    previous_request_id=requestID.
+    // 7. Re-apply the new payload to the entity (write-then-approve):
+    //    apply the counter_payload's field updates + mark
+    //    approval_status='pending' + pending_request_id=newRequestID.
+    // 8. Emit *_approval_changes_suggested project_events row
+    //    (metadata: note, counter_payload diff vs original).
+    // 9. Emit *_approval_requested project_events row for the new
+    //    request (same shape Submit* normally emits).
+    // 10. Commit.
+}
+```
+
+Steps 6 + 7 reuse the existing `Submit*` plumbing structurally — the cleanest implementation factors out an "insert approval row + apply payload to entity" helper that both `Submit*` and `SuggestChanges` call. **decide()** does not need to know about `changes_requested` because suggest-changes is not a decision-kernel transition — it's its own end-to-end action.
+
+### 3.3 HTTP layer
+
+```
+POST /api/approval-requests/{id}/suggest-changes
+  Body: {
+    "counter_payload": { ...same shape as Submit*'s payload... },
+    "note":            "free-text explanation, optional iff counter_payload differs from original"
+  }
+  Returns: 200 { "new_request_id": "uuid" }
+  Errors:
+    400 "suggestion_requires_change" — counter_payload == old payload AND note empty
+    400 "invalid_counter_payload"   — schema validation failure
+    403 "self_approval_blocked"     — caller == old row's requested_by
+    403 "not_authorized"            — caller doesn't satisfy canApprove
+    404                              — request not found / not visible
+    409 "request_not_pending"       — old row already decided
+    409 "no_qualified_approver"     — deadlock on the new row (only caller is eligible)
+```
+
+Register in `internal/handlers/handlers.go` alongside the existing three:
+
+```go
+protected.HandleFunc("POST /api/approval-requests/{id}/suggest-changes", handleSuggestChangesApprovalRequest)
+```
+
+### 3.4 Frontend
+
+`frontend/src/client/views/shape-list.ts` — extend the pending-row action group to four buttons:
+
+```ts
+actions.appendChild(approvalActionBtn("approve", detail));
+actions.appendChild(approvalActionBtn("suggest_changes", detail));
+actions.appendChild(approvalActionBtn("reject", detail));
+actions.appendChild(approvalActionBtn("revoke", detail));
+```
+
+The `action` union type gains `"suggest_changes"`. Disabled-reason logic is identical to approve/reject (`viewer_can_approve` gate). i18n: `approvals.action.suggest_changes` → DE "Änderungen vorschlagen" / EN "Suggest changes".
+
+`frontend/src/client/inbox.ts` — clicking the suggest-changes button opens a **modal**, not a `window.prompt` (the existing reject prompt is OK because reject only needs a note; suggest-changes needs an editable form). The modal:
+- Renders the same fields the entity edit form would show, pre-populated from `detail.payload` (the requester's proposed values).
+- Adds a free-text "Vorschlagskommentar" textarea at the bottom (the note).
+- On submit: POST `/api/approval-requests/{id}/suggest-changes` with `{counter_payload: {...editedFields}, note}`.
+- On success: refresh the bar — the old row flips to `changes_requested`, the new row appears as `pending`.
+
+Where the modal's field-editor lives: a new `client/components/approval-edit-modal.ts` that takes `entity_type` + `payload` + `pre_image` and returns the edited payload. For v1 it can be a thin wrapper over the existing entity-edit form components (Frist date picker, Termin start/end pickers). Don't build a generic field-editor framework — just deadlines + appointments, hard-coded fields per entity_type.
+
+**Status pill for `changes_requested`** — i18n keys + colour:
+- `approvals.status.changes_requested` → DE "Abgelehnt mit Vorschlag" / EN "Declined with changes"
+- Reuse the existing `approval-pill--historic` style; no new colour token needed for v1.
+
+**The "Edit and resubmit" CTA on the requester's row is NOT needed** (m's Q6 reframing) — the requester just sees the new pending row in /inbox, same as any other.
+
+### 3.5 Inbox filter
+
+The /inbox `approval_status` filter chip cluster gains `changes_requested`. The `self_requested` viewer-role default already includes terminal statuses, so the original requester sees their `changes_requested` row without changing the default filter.
+
+### 3.6 Linkage from old row to new row in /inbox
+
+When showing a `changes_requested` row in /inbox, add a small "→ Neuer Vorschlag von {approver}" link below the note that scrolls / filters to the new pending row (it'll be visible to anyone eligible, including the original requester). The new row has `previous_request_id` pointing at the old one — so the API response for the old row can hydrate `next_request_id` (computed: `SELECT id FROM approval_requests WHERE previous_request_id = $1 LIMIT 1`).
+
+### 3.7 Email notification (Phase 2 — defer until v1 ships)
+
+The new row triggers the existing `*_approval_requested` notification path (whatever that is for Submit*) — same audience, same template. No new code. The old row's transition to `changes_requested` doesn't need its own mail; the new-row mail already tells the audience "X suggested changes to your earlier submission" through the body.
+
+Out of scope for v1: a bespoke "your submission was declined with a counter-proposal" email aimed at the original requester. The new-row mail covers it functionally.
+
+---
+
+## 4. Slice plan
+
+Three reviewable slices, each one PR. Combined scope is small/medium.
+
+1. **Slice A — backend.** Migration 103 (CHECK extension + `counter_payload jsonb` + `previous_request_id` FK + index) + `SuggestChanges` service method + HTTP handler + service tests (happy path, no-op-suggestion guard, deadlock on new row, self-approval block, request_not_pending). Migration is non-blocking on Postgres; safe for live deploy.
+2. **Slice B — frontend.** 4th button on /inbox + the edit modal (deadline-fields variant + appointment-fields variant) + status pill `changes_requested` ("Abgelehnt mit Vorschlag") + i18n keys (DE + EN) + the "→ Neuer Vorschlag" link from old row to new row. End-to-end browser smoke test via Playwright.
+3. **Slice C — Verlauf integration.** Make sure the `*_approval_changes_suggested` event renders on the project / deadline / appointment Verlauf timeline alongside the existing 4 approval event types. May or may not need code change depending on how generic the Verlauf row renderer is — likely just an i18n key + an icon mapping.
+
+Don't ship a chain-traversal UI in v1. The `previous_request_id` FK is captured so the data is there; surfacing the full chain history (n hops back) is a Phase-2 polish.
+
+---
+
+## 5. Risks / open considerations
+
+- **Chain depth runaway.** Nothing stops an "I keep suggesting / they keep counter-suggesting" loop. Same risk as comment threads on GitHub PRs. Out of scope to cap; the social pressure (each round is a 4-Augen action with a name attached) is the natural brake.
+- **Concurrent suggestions on the same pending row.** Two approvers click "suggest changes" at the same time? The existing `getRequestForUpdate` row-lock serialises them; the second caller gets `ErrRequestNotPending` (the first already flipped it). Same guarantee as Approve/Reject today.
+- **Deadlock on the new row.** If the suggesting approver is the only qualified approver other than the original requester, the new row's deadlock check returns "no qualified approver" — because the original requester IS now eligible (they're no longer the requested_by), but might not have a high-enough role. The check needs to recognise: caller's pool = "anyone other than the new requester who can canApprove". Original requester counts if they hit the required-role bar. This is just the existing deadlock predicate run against the new (requester, role) tuple; no special-case logic. Surfaced as `409 "no_qualified_approver"` to the suggesting approver, with the standard global_admin override path still available.
+- **Counter-payload schema validation.** Server must validate `counter_payload` against the same schema as a normal `Submit*` for that entity_type + lifecycle_event. Otherwise a malicious approver could write garbage values via the suggestion path that wouldn't fly through `Submit*`. Reuse the existing payload-schema validator from the entity services; don't write a parallel.
+- **No-op suggestion guard.** Approver clicks suggest-changes but doesn't actually edit anything AND leaves the note empty? Server rejects with `ErrSuggestionRequiresChange`. UI guards too (the submit button stays disabled until either the form is dirty OR the note has text).
+- **Migration safety.** Non-blocking. Adding a value to a CHECK constraint is a metadata-only change; adding a NULLable column + a NULLable FK is also metadata-only.
+- **What about a structured per-field suggestion (Q4c)?** The `counter_payload` jsonb IS structured — each entity_type has fixed fields. There's no need for a separate "{field, current, suggested}" shape because the diff is computable from `pre_image → counter_payload` on the new row.
+- **What about thread-of-notes (Q4b)?** Implicit in the chain — each row's `decision_note` is one "note" by one author; following `previous_request_id` backwards reconstructs the full back-and-forth. A future "thread view" UI is layered on top of this without schema change.

+- "Dismiss this row from my inbox" UI toggle (UX-only, not a data-model change).

+# CalDAV multi-calendar sync — design
+
+**Task:** t-paliad-212
+**Inventor:** leibniz (2026-05-19)
+**Branch:** mai/leibniz/inventor-caldav-multi
+**Status:** READY FOR REVIEW — m's decisions on the §8 open questions captured in the addendum below (2026-05-19).
+
+---
+
+## §0 — One-paragraph summary
+
+Paliad's CalDAV sync today is a single-target push: every user has one
+`paliad.user_caldav_config` row, and every Appointment they can see gets
+PUT into that one calendar. m wants users to pick their own organization —
+one cal with everything, one cal per project (or per client / litigation /
+patent / case), or any hybrid. This design splits the model in two:
+**credentials stay per user** (one CalDAV server, one auth blob) and
+**bindings become first-class rows** (a join table `paliad.user_calendar_bindings`
+that points an Appointment-filter scope at a specific `calendar_path`).
+Push/pull state migrates from scalar `appointments.caldav_uid`/`caldav_etag`
+columns to a per-(appointment, binding) join table
+`paliad.appointment_caldav_targets`, so the same Appointment can live in
+N external calendars at once. The 60-second per-user sync goroutine survives
+unchanged in shape; inside it the inner loop iterates bindings instead of
+hard-coding `cfg.CalendarPath`. Sliced for safe rollout: Slice 1 introduces
+the new tables behind a backfill that auto-creates one binding per
+existing config row (zero behaviour change); Slice 2 ships the
+binding-picker UI; Slice 3 wires scope-aware filtering (one cal per project).
+Bidirectional sync stays exactly as it works today (last-write-wins on ETag,
+Paliad-owned UIDs only) — multi-calendar does not change the conflict
+model.
+
+---
+
+## §1 — What's already built (verified live, 2026-05-19)
+
+Verified against the codebase, not the project's CLAUDE.md.
+
+- **Schema** — `paliad.user_caldav_config` is one row per user with
+  `(user_id PK, url, username, password_encrypted bytea, calendar_path,
+  enabled, last_sync_at, last_sync_error, created_at, updated_at)`. The
+  scalar `calendar_path` is the only handle on which external calendar
+  receives events. Per direct `information_schema` query.
+- **Appointment binding** — `paliad.appointments` carries scalar
+  `caldav_uid text` and `caldav_etag text` (nullable). Set once after a
+  successful PUT via `AppointmentService.SetCalDAVMeta`. This is the
+  single-target assumption baked into the row itself.
+- **Sync engine** — `internal/services/caldav_service.go:298–502`. One
+  goroutine per enabled user, 60s ticker, `runSyncOnce` → `syncOnce` →
+  `pushAll` (`AppointmentService.AllForUser` × `cli.PutEvent`) +
+  `pullAll` (`cli.PropfindCalendar` → `cli.GetEvent` → reconcile by UID).
+  `AllForUser` returns *every* personal-or-visible-project appointment
+  for the user; today they all funnel into the single `calendar_path`.
+- **UID convention** — `paliad-appointment-<uuid>@paliad.de`
+  (`caldav_ical.go:31–34`). Foreign UIDs are intentionally skipped on
+  pull (`caldav_service.go:436–442`).
+- **Hooks** — `OnAppointmentCreated/Updated/Deleted` push directly to
+  the configured `cfg.CalendarPath` on a 30s-timeout background goroutine
+  so user requests don't block (`caldav_service.go:510–558`).
+- **Approval flow (t-138)** — project-attached appointments may be
+  `approval_status = 'pending'`. CalDAV push already runs after approval
+  in `AppointmentService.Update` paths; `ApplyRemoteUpdate` from a remote
+  edit currently bypasses the approval gate. That's a pre-existing hole
+  flagged here only because multi-calendar makes "which calendar's edit
+  wins" more visible — fix belongs in t-138 follow-ups, not in this
+  design.
+- **CalDAV verbs supported** — PUT / DELETE / GET / PROPFIND (depth 0
+  and 1). No MKCALENDAR, no REPORT, no calendar-multiget. Tested
+  against Nextcloud, Radicale, Baikal, mailcow SOGo per
+  `caldav_client.go:22–24`.
+
+**What is _not_ baked in and is therefore free to extend:**
+
+- The 60s ticker is per-*user*, not per-*calendar*. Adding bindings does
+  not multiply tickers.
+- `cfg.CalendarPath` is referenced in exactly two places (`pushAll`,
+  `pullAll`) plus the three hooks. Replacing it with a binding loop is
+  a contained edit.
+- Credentials are server-scoped, not calendar-scoped — every binding
+  for the same user shares the existing decrypted credential, so the
+  encryption layer (`caldav_crypto.go`) is untouched.
+
+---
+
+## §2 — Per-provider calendar-count limits (verified 2026-05-19)
+
+Real numbers, from current docs, so the design knows its envelope.
+
+| Provider | Per-account / per-user limit | Source |
+|---|---|---|
+| **iCloud** | **100** calendars + reminder-lists combined | [Apple Support 103188](https://support.apple.com/en-us/103188) |
+| **Google Calendar** | **~100 owned** (soft recommendation, post-Nov-2025 ownership model) | [Workspace Updates 2026-01](https://workspaceupdates.googleblog.com/2026/01/automatic-addition-owned-secondary-calendars.html), [usecarly.com summary](https://www.usecarly.com/blog/how-many-calendars-google-account/) |
+| **Fastmail** | **No documented cap on calendars.** 100 000 events/user. | [Fastmail account-limits page](https://www.fastmail.help/hc/en-us/articles/1500000277382-Account-limits) |
+| **Nextcloud** | **30 per user** default; admin-configurable, `-1` = unlimited. Rate limit: 10 calendar-creations/hour. | [Nextcloud admin manual — Calendar](https://docs.nextcloud.com/server/stable/admin_manual/groupware/calendar.html) |
+| **Radicale / Baikal / mailcow SOGo** | No published per-account cap (file-system / DB bound). | server defaults |
+
+**Implications for the design:**
+
+- "One calendar per project" is comfortably within all providers'
+  envelopes for typical HLC caseloads. A senior PA who tracks 40
+  litigations would land 40+ calendars, still inside iCloud's 100 and
+  Nextcloud's default 30 (would need an admin bump on Nextcloud — flag
+  in onboarding).
+- "One calendar per case" can blow past Nextcloud's default 30 fast and
+  is a real risk on iCloud at the 60+ mark when combined with the
+  user's existing personal calendars + reminder lists. We should
+  **soft-cap** scope choices at the UI layer (warn at 20 bindings, hard
+  block at 80) rather than discover the limit by 5xx on PUT.
+- Google Calendar's CalDAV endpoint does **not** support `MKCALENDAR`
+  reliably — calendars must be pre-created in the Google UI. iCloud,
+  Fastmail, Nextcloud, Radicale, Baikal, SOGo all accept `MKCALENDAR`.
+  So the "auto-create a calendar per project" affordance is provider-
+  dependent and must degrade gracefully ("we couldn't create it for
+  you — please make `Project X` in your calendar app and paste its
+  URL").
+
+---
+
+## §3 — Proposed data model
+
+Three schema changes, no destructive migrations. The scalar
+`appointments.caldav_uid` / `caldav_etag` columns survive as a
+denormalised "default-binding" pointer through Slice 1 and 2; Slice 4
+drops them after telemetry confirms no path still reads them.
+
+### §3.1 New table: `paliad.user_calendar_bindings`
+
+```sql
+CREATE TABLE paliad.user_calendar_bindings (
+  id              uuid PRIMARY KEY DEFAULT gen_random_uuid(),

+
+  UNIQUE (user_id, calendar_path),                                -- can't bind one calendar twice for the same user
+  UNIQUE (user_id, scope_kind, scope_id),                         -- one binding per scope per user — but a project can also be covered by 'all_visible'
+  CHECK ((scope_kind IN ('all_visible','personal_only') AND scope_id IS NULL)
+      OR (scope_kind NOT IN ('all_visible','personal_only') AND scope_id IS NOT NULL))
+);
+CREATE INDEX user_calendar_bindings_user_idx ON paliad.user_calendar_bindings(user_id) WHERE enabled;
+-- RLS: row visible/writable only when auth.uid() = user_id (mirrors user_caldav_config).
+```
+
+**Why per-scope unique but not per-appointment unique:** an Appointment in
+project P is allowed to land in both the user's `all_visible` calendar
+AND their `project=P` calendar — that's the explicit "master + per-project"
+hybrid m asked about. What we forbid is two different `project=P` bindings
+for the same user, which would have no useful semantics.
+
+**`scope_kind = 'personal_only'`** is a separate scope from `'all_visible'`
+because the existing pushAll already covers both personal and visible-project
+appointments; users may want a "personal only" calendar that does *not*
+get the noisy team events. Without this, every binding either includes
+personal events or doesn't, and there's no way to say "the master
+calendar = everything except personal".
+
+### §3.2 New table: `paliad.appointment_caldav_targets`
+
+```sql
+CREATE TABLE paliad.appointment_caldav_targets (
+  appointment_id uuid NOT NULL REFERENCES paliad.appointments(id) ON DELETE CASCADE,
+  binding_id     uuid NOT NULL REFERENCES paliad.user_calendar_bindings(id) ON DELETE CASCADE,
+  caldav_uid     text NOT NULL,        -- still 'paliad-appointment-<uuid>@paliad.de' — same for all bindings of one appointment
+  caldav_etag    text NOT NULL,
+  last_pushed_at timestamptz NOT NULL DEFAULT now(),
+  PRIMARY KEY (appointment_id, binding_id)
+);
+CREATE INDEX appointment_caldav_targets_binding_idx ON paliad.appointment_caldav_targets(binding_id);
+-- RLS: visible/writable when the underlying binding's user_id = auth.uid().
+```
+
+**UID stays per-appointment, not per-binding.** That keeps the iCal UID
+canonical (still `paliad-appointment-<uuid>@paliad.de`), so when a user
+removes a binding and re-adds it later, the same UID rebinds without
+spurious duplicates. The `.ics` filename in the calendar — `<uid>.ics`
+— is also identical across bindings, which means the same UUID
+shows up in different calendars on the same server but never collides
+because they're under different `calendar_path` collections.
+
+### §3.3 Row examples for the four common organisations
+
+| Organisation | Rows in `user_calendar_bindings` |
+|---|---|
+| **A — one cal, everything** | 1 row: `scope_kind='all_visible'`, `calendar_path='/cal/work'` |
+| **B — one cal per project** | N rows, all `scope_kind='project'`, distinct `(scope_id, calendar_path)` |
+| **C — master + per-project hybrid** | 1 row `scope_kind='all_visible'` + N rows `scope_kind='project'`. Each project event appears in both. |
+| **D — personal split from work** | 1 row `scope_kind='personal_only'` → `/cal/personal` + 1 row `scope_kind='all_visible'` (which will include the same personal events, so the user will more commonly pair `personal_only` with a `scope_kind='client'` per-client work view instead). |
+
+### §3.4 What stays unchanged
+
+- `paliad.user_caldav_config` — still holds the server URL, username,
+  encrypted password, and a per-user `enabled` flag. The existing
+  `calendar_path` column becomes a hint for the **default binding** we
+  auto-create on migration and is no longer read by sync logic after
+  Slice 1 ships. We keep it nullable-on-read for forwards-compat then
+  drop in Slice 4.
+- `paliad.caldav_sync_log` — still per-user; sync entries gain a
+  `binding_id` column (nullable for legacy rows) so the UI can show
+  per-calendar last-sync state.
+- iCal serialisation (`caldav_ical.go`) — unchanged. Same VEVENT
+  formatter feeds every binding.
+- AES-GCM credential encryption (`caldav_crypto.go`) — unchanged.
+
+---
+
+## §4 — Sync engine implications
+
+The shape of the per-user goroutine stays. The body of `syncOnce`
+moves from "push to one path / pull from one path" to "for each
+enabled binding, push the scope-filtered slice / pull from that path".
+
+### §4.1 Push fan-out
+
+```go
+// pseudocode for the new pushAll body
+bindings := s.bindings.ListEnabled(ctx, userID)              // 1..N rows
+for _, b := range bindings {
+    appts := s.appointments.ForBinding(ctx, userID, b)       // scope-filtered
+    for _, a := range appts {
+        body := formatAppointment(&a)
+        etag, err := cli.PutEvent(ctx, b.CalendarPath, terminUID(a.ID), body)
+        if err != nil { continue }                            // best-effort, per-binding error
+        s.targets.Upsert(ctx, a.ID, b.ID, terminUID(a.ID), etag)
+    }
+    // Remove events from this calendar that no longer belong to the scope.
+    for _, stale := range s.targets.DanglingForBinding(ctx, b.ID, currentIDs(appts)) {
+        cli.DeleteEvent(ctx, b.CalendarPath, stale.CalDAVUID)
+        s.targets.Delete(ctx, stale.AppointmentID, b.ID)
+    }
+}
+```
+
+`ForBinding(userID, b)` is the scope filter:
+
+- `all_visible` → existing `AllForUser(userID)`
+- `personal_only` → appointments with `project_id IS NULL AND created_by = userID`
+- `project` → appointments where `project_id = scope_id` AND visible to user
+- `client` / `litigation` / `patent` / `case` → appointments where the
+  ancestor at the relevant hierarchy level = `scope_id` AND visible to user
+- when `include_personal = true`, union with personal events on top of the above (only for non-`all_visible`/`personal_only` scopes)
+
+This reuses the existing `can_see_project()` predicate (per project
+CLAUDE.md, team-based RLS), so visibility shrinkage on a project unshare
+falls out naturally: next push sees the appointment is no longer in
+`ForBinding(...)`, sees a dangling target row, issues `DeleteEvent`.
+
+### §4.2 Pull reconciliation
+
+Each binding has its own pull pass against `b.CalendarPath`. The
+matching key is still `caldav_uid` — same UID across all bindings, so
+`appointments.FindByCalDAVUID(uid)` resolves the local row. The
+**ETag check is per-target row** now, not per-appointment: a remote
+edit in calendar X bumps the etag in `appointment_caldav_targets` for
+binding X only. The local Appointment is updated once (last-write-wins
+on Appointment.updated_at), the next push tick re-syncs the other
+bindings with the new payload (they see their stored etag is older
+than the appointment's `updated_at` and re-PUT).
+
+**One subtle change:** the foreign-UID skip (`extractAppointmentID == ""`)
+still applies per-binding pull. That preserves the v1 "Paliad owns its
+UIDs" property — multi-calendar does not open the door to importing
+events the user creates in their calendar app. (If/when that becomes
+in-scope, it's a separate t-paliad-* design.)
+
+### §4.3 Hooks (instant push)
+
+`OnAppointmentCreated/Updated/Deleted` fan out across all the user's
+enabled bindings that match the appointment's scope. Same 30s-timeout
+background goroutine. The user-facing request still returns
+immediately; the failure mode is identical (best-effort per binding,
+logged on `slog.Warn`).
+
+### §4.4 Bandwidth & rate limits
+
+- Per user per tick: **N bindings × 1 PROPFIND + per-event GETs**.
+  The pull GET is the dominant cost; a 50-binding user with 20 events
+  per calendar is ~1 000 GETs/min, which is fine over HTTP/1.1 to a
+  decent CalDAV server but **does** put us inside iCloud's
+  ~throttle-friendly band and risks Google's quota model.
+- Mitigation: switch pull to **`REPORT` `calendar-multiget`** so each
+  binding's events come back in one round-trip. That's a single
+  iteration on `caldav_client.go` (the same multistatus parser
+  already handles the body) and pays for itself the moment a user
+  has >10 events per binding. We deliberately deferred this in
+  Phase F (one calendar, low volume) — multi-calendar makes it
+  table-stakes. Plan to land it in **Slice 2** alongside the picker.
+- Rate limiting on the Paliad side: keep the 60s ticker, but stagger
+  per-binding pulls so we never fire N concurrent PROPFINDs against
+  the same provider. Sequential per binding is fine; we already do
+  this implicitly with the per-user goroutine.
+
+### §4.5 Server-side cleanup on binding delete
+
+User deletes a binding → service:
+
+1. Lists every (appointment, binding) target row for that binding.
+2. Issues `DELETE` per `.ics` on the remote calendar (best effort).
+3. Deletes the target rows.
+4. Deletes the binding row (or relies on `ON DELETE CASCADE` from
+   target FK — cleaner to delete remotely first, then drop the row,
+   so a half-failed cleanup leaves rows we can retry on next tick).
+
+A "leave events behind in the external calendar" toggle is a real
+ask (users sometimes archive bindings without wanting their calendar
+app to suddenly empty). Plumb it as `binding.cleanup_on_delete bool`
+in Slice 2 if there's demand; default `true` (delete).
+
+---
+
+## §5 — Bidirectional vs one-way
+
+**Recommendation: stay bidirectional, identical to today's semantics,
+per-binding.** Reasons:
+
+1. **m's stated workflow expects round-trip.** Drag a deadline in
+   Outlook → Paliad sees the new date → approval flow triggers
+   (t-138). One-way push breaks that. Multi-calendar doesn't change
+   this expectation; if anything, it strengthens it (the user picked
+   the project-cal binding *because* they intend to edit there).
+2. **The conflict model is already in place.** Last-write-wins on
+   ETag, foreign-UID skip, `LogConflict` audit append. Multi-calendar
+   adds one new question: "if the user edits the same event in two
+   different bindings between ticks, which wins?" Answer: the one
+   that lands first in our pull pass. Bindings are iterated in
+   `created_at` order so the behaviour is deterministic, and the
+   second edit gets overwritten on the next tick when we re-push the
+   resolved appointment to it. Acceptable trade-off; would only show
+   up if a user actually edits the same event in two of their own
+   calendars within 60s, which is vanishingly rare.
+3. **Approval-flow integration is unchanged.** Pending-approval
+   events have the `[PENDING APPROVAL]` marker baked into the iCal
+   summary by `caldav_ical.go:76+`. That marker survives multi-binding
+   fan-out untouched; an external edit on a pending event still has
+   the pre-existing bypass-the-gate hole (flagged §1, not in scope).
+
+**Tee-up for m's call:** if multi-calendar is the wrong moment to
+keep bidirectional (e.g. because per-project calendars are about
+**read-only visibility for partners**, not editing), we'd add a
+`binding.read_only bool` column and skip the pull pass for that
+binding. Cheap to add now or later. **I recommend defaulting
+`read_only = false` (bidirectional like today) and only making it
+optional if m's first session with the UI surfaces the need.**
+
+---
+
+## §6 — User-facing config model
+
+Surface on `/einstellungen/caldav` (already exists for Phase F creds).
+Two sections, in this order:
+
+1. **Server** (existing) — URL, username, password, "test connection".
+   Unchanged.
+2. **Calendars** (new) — list of bindings as cards / rows. For each:
+   `display_name`, `calendar_path`, `scope_kind` chip (master /
+   personal / project / …), `enabled` toggle, last-sync status, action
+   buttons "Edit scope" / "Remove".
+3. **Add a calendar** — flow:
+   - **a)** click "Add". Modal opens. We do a `PROPFIND
+     <calendar-home-set>` against the user's server to discover their
+     existing calendars; show as a picker. (RFC 6638 / 4791 calendar
+     home set discovery — supported by iCloud, Fastmail, Nextcloud,
+     Radicale, Baikal, SOGo. Google CalDAV does not expose this
+     reliably; for Google users we degrade to a manual path entry box.)
+   - **b)** user picks an existing calendar, or chooses "Create new
+     calendar". Create-new attempts `MKCALENDAR` (works on iCloud,
+     Fastmail, Nextcloud, Radicale, Baikal, SOGo; fails on Google →
+     friendly error with copy-paste instruction).
+   - **c)** user picks the **scope**: a radio between "Everything I can
+     see", "Personal only", "One project", and (later) "One client /
+     litigation / patent / case". Project picker uses the existing
+     `/api/projects?…` autocomplete.
+   - **d)** "Save" → POST `/api/caldav-bindings`. The next 60s tick
+     starts pushing into the new calendar; the UI shows "Initial
+     sync running…" with a live last-sync indicator (already polled
+     by the existing `caldav-config` page).
+
+4. **Quick-add affordances** (Slice 3 polish, not v1):
+   - On a project's `/projects/<id>` page: "Open in calendar app" link
+     if a binding already exists for that project, "Pin to a new
+     calendar" if none does (deep-links to the Add-a-calendar modal
+     pre-filled).
+   - Bulk action "Create one calendar per active litigation" on
+     `/einstellungen/caldav` (requires `MKCALENDAR` support; gated
+     behind a server-capability probe at first PROPFIND).
+
+5. **Soft limits in the UI:**
+   - At **20 bindings**: yellow info banner "Most users keep ≤ 20
+     calendars; review your list before adding more."
+   - At **80 bindings**: red error, block adding new (we don't know
+     the user's provider for sure; 80 is a safe ceiling for iCloud
+     and Nextcloud-default).
+   - Provider hint surfaced under the Server form: parsed from the
+     URL host, with a "your provider's documented limit" line —
+     pure courtesy, not enforced.
+
+### §6.1 What the API contract looks like
+
+| Verb + Path | Body / Returns | Notes |
+|---|---|---|
+| `GET /api/caldav-bindings` | array of binding rows + sync status | replaces having to interpret `user_caldav_config.calendar_path` |
+| `POST /api/caldav-bindings` | `{calendar_path, display_name, scope_kind, scope_id?, include_personal?}` → created binding | triggers immediate sync goroutine wake-up |
+| `PATCH /api/caldav-bindings/{id}` | partial; toggle `enabled` or change `scope_*` | re-runs `pushAll` for this binding |
+| `DELETE /api/caldav-bindings/{id}` | — | deletes external events first, then row |
+| `GET /api/caldav-discover` | array of `{href, displayname}` from server `<calendar-home-set>` | populates the picker; cached 5 min |
+| `POST /api/caldav-mkcalendar` | `{display_name, color?}` → `{calendar_path}` | issues `MKCALENDAR`; returns 501 on Google |
+
+`GET /api/caldav-config` still works (back-compat for the server-creds
+section); its `calendar_path` field is documented as "deprecated, see
+/api/caldav-bindings".
+
+---
+
+## §7 — Slice plan
+
+Tracer-bullet slices so each is independently shippable, safe to
+revert, and gives the user something they can see.
+
+**Slice 1 — Schema + backfill (no UI change).**
+- Migration: create `user_calendar_bindings`, `appointment_caldav_targets`.
+- Backfill: for every existing `user_caldav_config` row, insert one
+  `bindings` row `(user_id, calendar_path, display_name='', scope_kind='all_visible', enabled)`.
+  For every Appointment with non-null `caldav_uid`, insert one
+  `appointment_caldav_targets` row pointing at the user's new default
+  binding.
+- Refactor `CalDAVService.syncOnce` / `pushAll` / `pullAll` to drive
+  off bindings (loop of length 1 per existing user). Behaviour
+  observably identical: same calendars, same events, same logs.
+- `appointments.caldav_uid` / `caldav_etag` columns still exist and
+  are written for compatibility (treat them as denormalised pointers
+  to the default binding's target row). UI unchanged.
+- **Exit criterion:** existing users see no change in their calendar;
+  `caldav_sync_log.binding_id` is populated for all new rows; manually
+  inserted second binding via SQL syncs correctly end-to-end on a
+  staging account.
+
+**Slice 2 — Binding-picker UI + multi-binding support.**
+- `/api/caldav-bindings` CRUD + `/api/caldav-discover` (PROPFIND
+  `calendar-home-set`) + `/api/caldav-mkcalendar`.
+- New "Calendars" section on `/einstellungen/caldav` with the modal
+  flow from §6.
+- **Land `REPORT calendar-multiget` pull** alongside (per §4.4).
+  Required, not optional, for the bandwidth profile multi-binding
+  introduces.
+- Scope kinds enabled in v1: `all_visible`, `personal_only`, `project`.
+  Hierarchy scopes (`client`, `litigation`, `patent`, `case`) parked
+  for Slice 3.
+- **Exit criterion:** m can pin a second calendar via the UI on
+  staging; events for project X appear only in the X-bound calendar
+  if his master binding is disabled, and in both if it's enabled.
+
+**Slice 3 — Hierarchy scopes + project-page quick-adds.**
+- Enable `scope_kind ∈ {client, litigation, patent, case}` — pure
+  filter-predicate change in `ForBinding(...)` using the existing
+  project-tree walker.
+- "Pin to a new calendar" button on `/projects/<id>` and on the
+  /einstellungen page.
+- Bulk "calendar-per-active-litigation" provisioner (with
+  `MKCALENDAR` capability probe).
+- **Exit criterion:** real HLC PA can set up "one cal per
+  litigation" in <5 min on first try without inventor help.
+
+**Slice 4 — Polish + cleanup.**
+- Drop `appointments.caldav_uid` / `caldav_etag` after instrumentation
+  shows zero readers outside `CalDAVService` (`grep` + a one-week
+  query-log audit on the read replica).
+- Soft-limit banners (20 / 80).
+- `binding.read_only` and `binding.cleanup_on_delete` toggles if
+  asked for by then.
+- **Exit criterion:** schema is final; no legacy paths remain in
+  `caldav_service.go`.
+
+**(Out of scope across all four slices:** foreign-UID import, custom
+event types per binding, per-binding colour mapping, MKCALENDAR for
+Google. These are easy to add later if the data says so.)
+
+---
+
+## §8 — Open questions for m
+
+1. **Bidirectional default for new bindings: yes/no?** I recommend
+   **yes** (matches today's single-cal behaviour and the round-trip
+   workflow expectation). A `read_only` per-binding flag is cheap to
+   add later if a real use case shows up. Decide now → Slice 1; decide
+   later → Slice 4.
+2. **`personal_only` scope — keep or drop?** It's useful for users
+   who want a "noisy team master + clean personal" split, but it's
+   redundant for users who only use the master calendar. I'd keep
+   it; trivial to remove if m disagrees.
+3. **`MKCALENDAR` (auto-create calendar) — ship in Slice 2 or defer
+   to Slice 3?** Shipping it in Slice 2 means we need the
+   capability-probe + Google-degrade UX up-front. Deferring means
+   Slice 2 users have to pre-create the calendar in their app and
+   paste the URL — workable but clunky. Default plan: **Slice 2,
+   with a clean Google-degrade message**.
+4. **Soft cap numbers (20 / 80) — sensible?** Picked from §2
+   provider limits + "most paliad users will pick 1–5". m may
+   want different numbers — easy to tune.
+5. **`/admin/caldav-bindings` view for support debugging?** Not in
+   the slice plan; useful if a user calls confused about which
+   calendar holds which event. Add if m wants it.
+6. **Approval-flow + remote-edit gap (§1, the bypass) — fix scope?**
+   Pre-existing in single-cal Phase F. Multi-cal makes it more
+   visible. Should this be a follow-up under t-138, or folded into
+   Slice 3? I'd file as a separate task.
+
+---
+
+## §9 — Why this is the right shape
+
+- **Single CalDAV server per user, N bindings.** Matches every real
+  provider's auth model (one auth blob covers all the user's
+  calendars) and keeps `caldav_crypto.go` and `user_caldav_config`
+  untouched.
+- **Binding scope is a row, not a static config.** Users compose
+  the organisation they want without us guessing; defaults (one
+  master binding on migration) preserve current behaviour.
+- **UID stays per-appointment.** Means an event re-binding (move
+  from project-cal to master-cal) is just shuffling target rows,
+  not minting new UIDs. Re-importing into the same calendar later
+  rebinds cleanly.
+- **Sync engine shape is unchanged.** Same per-user goroutine, same
+  60s tick, same hooks. The blast radius of multi-binding is one
+  inner loop, gated behind a feature that backfills to a no-op for
+  every existing user.
+- **Slices give m a vertical demo at each step.** Slice 1 is
+  invisible-but-shippable; Slice 2 is the first user-facing change
+  ("you can pin a second calendar"); Slice 3 is "now organise by
+  project tree"; Slice 4 is cleanup.
+- **No new external dependencies.** Same hand-rolled CalDAV client.
+  Adds one new verb (`MKCALENDAR`) and one new report
+  (`calendar-multiget`) — both small, both already half-tested
+  against `caldav_client.go`'s patterns.
+

+
+## Addendum — m's decisions (2026-05-19)
+
+Walked through §8.1–§8.6 with m via AskUserQuestion. Decisions are
+locked in for the coder shift; revisit only on Slice-3 feedback.
+
+| Q | Decision | Implication for the slice plan |
+|---|---|---|
+| **§8.1 — Bidirectional default** | **Yes — bidirectional by default** | No `read_only` flag in Slice 1–3. Multi-cal inherits Phase F's last-write-wins / foreign-UID-skip semantics unchanged. Per-binding `read_only` only added later if a real use case shows up. |
+| **§8.2 — `personal_only` scope** | **Keep — first-class scope** | Ships in Slice 2 as one of the picker's radio options (`Everything I can see` / `Personal only` / `One project`). One enum value, one `ForBinding()` branch. |
+| **§8.3 — MKCALENDAR timing** | **Slice 2 with Google-degrade UX** | Slice 2 includes `POST /api/caldav-mkcalendar` + capability probe. Google users get a friendly "create the calendar in your Google UI, paste the URL" fallback. iCloud / Fastmail / Nextcloud / Radicale / Baikal / SOGo get one-click "Create new calendar". |
+| **§8.4 — Soft caps** | **No caps in v1, add later if data warrants** | Drop the 20-warn / 80-block UI guards from §6. Instrument `count(*)` on `user_calendar_bindings` per user as a Slice 2 telemetry add. Revisit if/when real distributions land. |
+| **§8.5 — `/admin/caldav-bindings` view** | **Don't ship in v1** | Stays out of the slice plan. Support debugging goes via Supabase SQL until a real ticket lands. Frees Slice 4 polish for the legacy-column drop only. |
+| **§8.6 — Approval-flow remote-edit gap** | **Separate task under t-138** | Out of scope for all four multi-cal slices. File the gap as a new `t-paliad-*` follow-up under t-138 so multi-cal stays clean and reverter-friendly. Pre-existing hole, surfaced not fixed. |
+
+### Net effect on §7 slice plan
+
+- **Slice 1** unchanged — schema + backfill, behaviour-equivalent.
+- **Slice 2** = picker UI + `REPORT calendar-multiget` + **MKCALENDAR
+  with capability probe + Google-degrade message** + binding-count
+  telemetry. No `read_only` flag, no soft caps, no admin view.
+  Scopes enabled: `all_visible`, `personal_only`, `project`.
+- **Slice 3** = hierarchy scopes (`client` / `litigation` / `patent` / `case`)
+  + per-project quick-adds. **No** approval-gap fix folded in.
+- **Slice 4** = drop legacy `appointments.caldav_uid` / `caldav_etag`.
+  Soft-cap banners only if Slice 2 telemetry says we need them.
+
+### Net effect on §3 schema
+
+No change. `user_calendar_bindings` still ships with the full
+`scope_kind` enum (including `personal_only`). `appointment_caldav_targets`
+unchanged. No `read_only` column in v1.
+
+### Follow-ups to file as separate tasks
+
+1. **`t-paliad-*` (under t-138):** approval-flow + CalDAV remote-edit
+   gap. `ApplyRemoteUpdate` bypasses the approval gate when an external
+   client edits a pending-approval event. Pre-existing in single-cal
+   Phase F. Owner: t-138 maintainer.
+2. **(maybe) `t-paliad-*`:** soft-cap UI if Slice 2 telemetry shows
+   any user near the iCloud-100 / Nextcloud-30 envelope. Not pre-filed
+   — only opens if data warrants.

+# Paliad data export — Excel-first, scoped (org / project-subtree / personal)
+
+Design: archimedes (inventor), 2026-05-19.
+Task: **t-paliad-214**.
+Branch: `mai/archimedes/inventor-excel-data`.
+Status: READY FOR REVIEW — no code yet, awaiting m go/no-go on §11 open questions.
+
+---
+
+## 0. Premise check (live state, 2026-05-19)
+
+Verified directly against the youpc Postgres `paliad` schema rather than against memory or older design docs.
+
+**Migration tracker.** Latest applied is `100_ccr_visible_rule`; next is **101**.
+
+**Row counts (org-wide today):**
+
+| table                  | rows |
+|------------------------|-----:|
+| users                  | 47   |
+| projects               | 11   |
+| deadlines              | 26   |
+| appointments           | 5    |
+| parties                | 0    |
+| notes                  | 4    |
+| documents              | 0    |
+| project_events (audit) | 93   |
+| project_teams          | 3    |
+| approval_requests      | 8    |
+| approval_policies      | 160  |
+| checklist_instances    | 4    |
+| deadline_rules         | 254  |
+| user_views             | 2    |
+| partner_units          | 11   |
+
+A full org export today is **< 600 rows of user content** plus reference data — synchronous streamed download is plausible for every scope. We design for an order-of-magnitude head-room.
+
+**Auth.** Passwords live in Supabase Auth (separate `auth` schema, not `paliad`). The `paliad.users` table has **no `password_hash` column** — so the "don't export credentials" rule from the brief is enforced by absence, not by a column-deny list. Good.
+
+**Visibility.** Row-level via `paliad.can_see_project(project_id)` (subtree-aware through ltree path). Already used as the predicate that gates every list endpoint. We reuse it for the **personal** and **project** scopes; the **org** scope bypasses it under `global_admin`.
+
+**Documents.** Table exists, 0 rows. Phase H (AI Frist-Extraktion) is deferred per m's 2026-04-16 call. No `ANTHROPIC_API_KEY` on Dokploy. Therefore **this design does not concern itself with binary attachments** — only with the metadata row when documents start landing.
+
+**Audit trail.** Lives in `paliad.project_events` (93 rows). One row per lifecycle event with `event_type`, `metadata jsonb`, `event_date`, `created_by`. The auditing union (`AuditService.ListEntries`) joins 5 sources (project_events, partner_unit_events, deadline_rule_audit, policy_audit_log, reminder_log). For the export we treat `project_events` as primary; the four auxiliary logs are scope-specific.
+
+**Existing export precedent.** `/admin/rules/export` + `/admin/api/rules/export-migrations` (handlers/admin_rules.go) — admin-gated, streams a generated SQL artifact. Same shape as what we want for the Excel exports. Re-use the gating helper.
+
+**No Go xlsx library on `go.mod` today.** This design picks **`github.com/xuri/excelize/v2`** in §3.
+
+---
+
+## 1. Why this exists
+
+Two motivations, both load-bearing:
+
+1. **Safety / backup.** A workbook on disk is a portable artifact independent of the running app. If paliad.de is down, a partner needs the matter file. If the Dokploy compose corrupts, IT needs a recent dump. If a deadline gets accidentally deleted, we want a recoverable snapshot.
+
+2. **No lock-in.** A team or an entire org choosing to leave paliad must be able to walk away with their entire dataset in a format anyone can open. We promise this in writing as a trust signal — exactly because the alternative (silently locking customers in) is what we built paliad to *not* be.
+
+The export is therefore not a "nice analytics feature" — it is **a contractual guarantee that the data is yours**. That framing shapes the design: completeness > convenience, portability > polish, every export auditable.
+
+---
+
+## 2. Scope definitions (precise)
+
+Three scopes. The boundary is **what the caller is allowed to see**, joined with **what makes the artifact interpretable standalone**.
+
+### 2.1 `org` scope
+
+**Caller:** `global_role='global_admin'` only. There is no firm-admin role distinct from global_admin in paliad today (see §4).
+
+**Content:** literally everything in the `paliad` schema that is user content or reference data the workbook needs to be readable. Specifically:
+
+| sheet                  | source table(s)                                                   | notes |
+|------------------------|-------------------------------------------------------------------|-------|
+| `projects`             | `paliad.projects` (all rows)                                      | Full project tree including soft-deleted (status='deleted' / 'closed' if any). |
+| `project_teams`        | `paliad.project_teams`                                            | profession + responsibility (post-t-148). |
+| `project_partner_units`| `paliad.project_partner_units`                                    | Derivation grants. |
+| `deadlines`            | `paliad.deadlines`                                                | Including completed, cancelled. |
+| `appointments`         | `paliad.appointments`                                             | Including completed. |
+| `parties`              | `paliad.parties`                                                  | All client / opposing-party data. |
+| `notes`                | `paliad.notes`                                                    | All four polymorphic targets resolved into the `target_kind`/`target_id` columns. |
+| `documents`            | `paliad.documents` metadata (file_path, file_size, mime_type, ai_extracted) | Binaries excluded (open Q1). |
+| `audit_events`         | `paliad.project_events`                                           | Full audit trail per project. |
+| `approval_requests`    | `paliad.approval_requests`                                        | Including completed / rejected, with `requester_kind` + `agent_turn_id`. |
+| `approval_policies`    | `paliad.approval_policies`                                        | Both project-scoped and partner-unit-defaults. |
+| `policy_audit_log`     | `paliad.policy_audit_log`                                         | Source #5 of the audit union. |
+| `partner_units`        | `paliad.partner_units`                                            | Org chart. |
+| `partner_unit_members` | `paliad.partner_unit_members`                                     | Including unit_role. |
+| `partner_unit_events`  | `paliad.partner_unit_events`                                      | Org-chart audit. |
+| `checklist_instances`  | `paliad.checklist_instances`                                      | Per-project completion state. |
+| `invitations`          | `paliad.invitations` (status, role, expires_at)                   | Without raw tokens (open Q7). |
+| `users`                | `paliad.users` (id, email, display_name, office, profession, …)   | Excludes `email_preferences` jsonb only if it carries channel secrets — none do today, but checked at export time. |
+| `user_views`           | `paliad.user_views`                                               | Saved filters / custom layouts. |
+| `user_card_layouts`    | `paliad.user_card_layouts`                                        | Project-card layouts. |
+| `user_pinned_projects` | `paliad.user_pinned_projects`                                     | Per-user pins. |
+| `user_caldav_config`   | `paliad.user_caldav_config` **without** the ciphertext column     | URL + calendar IDs + last_sync; passwords NEVER exported. |
+| `reminder_log`         | `paliad.reminder_log`                                             | Outbound digest history. |
+| `caldav_sync_log`      | `paliad.caldav_sync_log`                                          | Per-user sync runs. |
+| `paliadin_turns`       | `paliad.paliadin_turns`                                           | **Excluded by default** in org export (privacy — see §6) — admins opt in per Q5. |
+| `email_broadcasts`     | `paliad.email_broadcasts`                                         | Outbound broadcast history. |
+| `email_templates` + `_versions` | both                                                     | Custom firm templates. |
+| **reference (read-only):** | `proceeding_types`, `event_types`, `event_categories`, `deadline_rules`, `deadline_concepts`, `deadline_concept_event_types`, `deadline_event_types`, `event_category_concepts`, `trigger_events`, `holidays`, `courts`, `countries` | One sheet per table, prefixed `ref__`. Embedded so the workbook is interpretable without paliad context. |
+| **deferred audit (admin opt-in):** | `deadline_rule_audit`, `policy_audit_log`, `partner_unit_events`, `caldav_sync_log`, `paliadin_turns` | Behaviour per Q5/Q6. |
+
+**Excluded unconditionally:**
+- `auth.*` (Supabase Auth schema — not ours; the user can request their auth record from Supabase directly).
+- `paliad_schema_migrations` (operational, no business meaning).
+- `*_pre_NNN` shadow / pre-migration backup tables (rows are duplicates; the live table is canonical).
+- Any future `*_secret` / `*_token` columns (see §6 deny-list mechanism).
+
+**Edge cases:**
+- **Soft-deleted rows:** paliad currently has no soft-delete columns (`deleted_at` etc.). When that lands, the org export includes them by default with a `deleted_at` column populated. Until then, this is a no-op.
+- **Archived projects:** `projects.status` can be `'closed'` or future `'archived'` — export includes them (the whole point of backup is recoverability of closed matters).
+- **Counterclaims:** `projects.counterclaim_of` is a self-FK. Export carries the column as-is; the relationship is reconstructable via the `id` column.
+
+### 2.2 `project` scope
+
+**Caller:** any team member of the project who passes the §4 profession-tier gate.
+
+**Content:** one project + **all descendants** along the ltree path. The descendant walk is `WHERE path <@ root.path` (subtree-inclusive of root). Every entity gets filtered through `WHERE project_id IN (subtree_ids)`.
+
+Per-sheet inclusion:
+
+- `projects` (root + descendants, one row each)
+- `project_teams` (membership for those projects)
+- `project_partner_units` (derivation attachments)
+- `deadlines`, `appointments`, `parties`, `notes`, `documents` (metadata), `audit_events`, `approval_requests`, `checklist_instances` — all scoped to subtree
+- **users sheet — restricted columns:** only `id, email, display_name, office, profession` for users referenced by any FK in the export (created_by, assigned, etc.). Don't dump all 47 users when you only need 4. (Avoids accidental org-chart leak in a project-scope export shared externally.)
+- **reference data:** `ref__proceeding_types`, `ref__event_types`, `ref__deadline_rules`, `ref__deadline_concepts`, `ref__courts`, `ref__countries`, `ref__holidays`. Same as org but a smaller universe is acceptable too — the v1 ships the full reference tables for simplicity (every row count is ≤ 300; size is moot).
+- **Cross-project references** (e.g., a party referenced by a project outside the subtree): out of scope by the predicate. The export carries the foreign UUID so a re-import or merge could re-link, but the foreign row itself is not in the workbook. Edge case is rare — `counterclaim_of` is the only known cross-project pointer today.
+
+**Edge cases:**
+- **Partner-unit data:** `partner_units` is org-wide; project export carries only the unit ids attached via `project_partner_units`. The unit name + membership are loaded into the workbook on `partner_units` and `partner_unit_members` sheets (filtered to the attached units only).
+- **Policies:** `approval_policies` rows include both project-scoped (the project + ancestors) **and** partner-unit-defaults attached to this project. Same MAX-of-sources logic as runtime.
+- **Audit:** `project_events` for the subtree + (admin opt-in only) `deadline_rule_audit` rows whose rule was used by any deadline in the subtree. Default off — these are firm-wide curation logs and don't belong in a per-project handoff.
+
+### 2.3 `personal` scope
+
+**Semantics:** "everything I can see right now in paliad, framed as my data."
+
+That definition resolves the ambiguity in the brief: personal scope is **not** "rows where I am `created_by`" — that misses everything I see by being on a team. It is **the RLS-visible projection of the schema for caller=me**, plus a handful of explicitly-personal sidecars (caldav config, my pins, my views).
+
+Per-sheet inclusion:
+
+| sheet | rows |
+|---|---|
+| `projects` | `WHERE paliad.can_see_project(id)` for the caller. |
+| `project_teams` | Rows where `user_id = me` OR the row's project is in my visible set. |
+| `deadlines` | Same project-visibility filter. |
+| `appointments` | Same. |
+| `parties`, `notes`, `documents` metadata, `audit_events`, `checklist_instances` | Same. |
+| `approval_requests` | Rows where `requested_by = me` OR `decided_by = me` OR project ∈ visible set. |
+| `me` (single-row sheet) | Caller's `users` row (id, email, display_name, office, profession, reminder_*, lang, escalation_contact_id). |
+| `my_caldav_config` | The caller's `user_caldav_config` row **without** the encrypted password column — sync URL, calendar IDs, last_sync_at. |
+| `my_views` | Caller's `user_views` rows. |
+| `my_pinned_projects` | Caller's `user_pinned_projects` rows. |
+| `my_card_layouts` | Caller's `user_card_layouts` rows. |
+| `my_paliadin_turns` | Caller's `paliadin_turns` rows (currently restricted to `PaliadinOwnerEmail` = m, so this sheet is empty for everyone else). Sensitive: AI prompts + responses. **Default on for personal scope** — it's literally the caller's data. |
+| `users_referenced` | Restricted: id + display_name + email for users referenced as FKs in the export. |
+| reference tables | Same set as project scope. |
+
+**Edge cases:**
+- **Caller leaves a team:** the export reflects the moment-in-time visibility. A `generated_at` timestamp in the workbook header (`__meta` sheet) anchors this.
+- **Caller is a global_admin:** their personal export is the entire org (because their visible set = all projects). This is by design — but we surface a banner ("Sie sehen alles, weil Sie global_admin sind. Ein org-scope-Export wäre identisch.") so they don't get confused thinking the personal-scope endpoint is broken.
+- **Caller has no team memberships:** export contains the empty workbook + the `me` row + their caldav config + views/pins. Still useful — they can save their preferences.
+
+### 2.4 Common columns across all scopes
+
+Every export workbook contains a `__meta` sheet:
+
+```
+schema_version:     1
+firm_name:          HLC                       # from internal/branding.Name
+scope:              org | project | personal
+scope_root_id:      uuid or NULL              # the project id for project-scope, NULL otherwise
+generated_at:       2026-05-19T14:23:00Z
+generated_by_user:  <uuid> <email>            # the caller
+generated_by_label: archimedes / m / ...      # display_name
+row_counts:         JSON {"projects": 11, ...}
+paliad_version:     <git sha at server build>
+notes:              free-form, e.g., "documents binaries excluded by design"
+```
+
+This pins provenance + reproducibility + diffability.

+
+## 3. Format choices
+
+### 3.1 xlsx as the primary format
+
+**Library: `github.com/xuri/excelize/v2`.** De-facto Go xlsx library, pure-Go (no cgo, no external libreoffice), MIT, streaming writer for large workbooks, broad format-feature support (number formats, freeze panes, hyperlinks, sheet hide). The streaming writer (`NewStreamWriter`) is what we use — it writes rows one at a time without holding the whole sheet in memory. At 11-projects scale this is unnecessary; at 11k-projects scale it's essential, so we set the pattern now.
+
+**Why not the alternatives:**
+- `tealeg/xlsx` — older, unmaintained, no streaming.
+- `qax-os/excelize` — same project as xuri/excelize (the github org renamed); xuri is the upstream.
+- `360EntSecGroup-Skylar/excelize` — defunct fork.
+
+**Workbook structure:** one **sheet per entity type**, *never* a mixed-type sheet with conditional columns. Reasons:
+- Excel users sort + filter by column; a column that means "deadline due_date" on row 4 and "appointment start_at" on row 12 is unusable.
+- The "self-describing" promise (no-lock-in) is satisfied by a workbook where every sheet is a flat table with stable column headers, not by a polymorphic blob.
+- Cross-sheet relationships are represented by **UUIDs in foreign-key columns** + a `__lookup` sheet pairing UUID → display label (project title, user email) for the workbook's lifetime. This makes the workbook self-joining in Power Query / pivot tables.
+
+**Sheet conventions:**
+- Sheet names use `snake_case` matching SQL table names (`deadlines`, not `Fristen`). Reference tables prefixed `ref__`. Personal sidecars prefixed `my_`. Meta sheet `__meta`. The `__lookup` sheet sits last.
+- Row 1 = column headers; frozen.
+- Column 1 of every entity sheet is `id` (uuid).
+- Dates: ISO 8601 UTC for timestamptz; `YYYY-MM-DD` for `date`. Always as Excel strings (not Excel date types) — Excel-date interpretation differs by locale (DE: `Tag.Monat.Jahr`, EN: `Month/Day/Year`) and silently corrupts on round-trip. A pinned ISO string is unambiguous and re-importable. Open Q4 covers whether to *also* mirror to native Excel dates for human convenience.
+- Booleans: literal `TRUE` / `FALSE` strings, same reason.
+- `jsonb` columns: serialised as compact JSON one-liners in the cell. Cell type = string. Power Query can `Json.Document` them.
+- Arrays (e.g., `additional_offices text[]`): semicolon-joined string. Excel's CSV-array convention is the comma but our office codes use commas; semicolon avoids the collision.
+- `text[uuid[]]` paths (the projects.path ltree): exported as the canonical dotted-uuid string.
+
+**Encoding:** UTF-8 always. Excelize handles the xlsx packaging which is unicode-native. Umlaute round-trip correctly (verified pattern with tesla's CSV export in t-paliad-177).
+
+### 3.2 CSV + JSON siblings
+
+Per the no-lock-in promise, **xlsx is not enough on its own** — Excel is a proprietary format owned by Microsoft, and a workbook is opaque without a tool that understands it. For genuine portability we also produce:
+
+- **CSV:** one file per entity sheet (no reference sheets — those go as JSON), UTF-8 with BOM (`\xEF\xBB\xBF`) for Excel-DE compat, RFC 4180 quoting, headers row 1. Identical column shape to the xlsx sheet.
+- **JSON:** a single `paliad-export.json` per scope, top-level `{"meta": {...}, "tables": {"projects": [...], "deadlines": [...], ...}}`. Easiest for programmatic re-ingest. Reference tables included.
+
+**Delivery shape:** all three formats live inside one `.zip` per export:
+```
+paliad-export-<scope>-<timestamp>.zip
+├── README.txt              # human-readable: what this is, how to read it
+├── paliad-export.xlsx      # canonical workbook
+├── paliad-export.json      # JSON twin (machine-readable)
+├── csv/
+│   ├── projects.csv
+│   ├── deadlines.csv
+│   ├── ...
+│   └── ref/
+│       ├── proceeding_types.csv
+│       └── ...
+└── __meta.json             # standalone meta (same content as __meta sheet)
+```
+
+The `.zip` is the artifact users download. Default content is "all three" — there's no UI knob to pick (open Q1: should there be? Inventor pick = no, zip-only).
+
+**Filename convention:**
+```
+paliad-export-{scope}-{timestamp}.zip
+  scope     = org | project-<root-short> | personal
+  timestamp = YYYY-MM-DDTHHMMZ           # UTC, no colons (Windows-safe)
+```
+Examples: `paliad-export-org-2026-05-19T1423Z.zip`, `paliad-export-project-Siemens-AG-2026-05-19T1423Z.zip`, `paliad-export-personal-2026-05-19T1423Z.zip`. The project-short is `slugify(root.title)` capped 40 chars.
+
+**Determinism (Q6 question).** Two exports of the same scope at the same row state must produce **byte-identical** workbooks. xlsx is internally a zip of XML — file order in the zip is significant; excelize's default zip writer is non-deterministic. We can make this deterministic by sorting the file list before writing. JSON: keys sorted alphabetically. CSV: rows ordered by `id ASC` (stable). The only inherently non-deterministic field is `generated_at`; we externalise it to the filename and the `__meta` sheet, but the rest of the workbook is byte-stable. **Inventor pick: yes, deterministic.** Lets users diff exports and prove "nothing changed between Tuesday and Thursday."
+
+### 3.3 Future-proofing — schema_version
+
+`__meta.schema_version = 1`. When we add columns (e.g., projects.archived_at lands), we bump to 2 and note the additions in a `docs/export-schema-changelog.md`. Importers (us in the future, or a re-importer at a different firm) read schema_version first.
+
+---
+
+## 4. Authorization model
+
+**Tightly mirrored to existing paliad role surfaces.** No new roles introduced.
+
+| Scope | Required auth |
+|---|---|
+| `org` | `paliad.users.global_role = 'global_admin'`. Same gate as `/admin/*` pages (`auth.RequireAdminFunc` in `handlers.go:417`). |
+| `project` | Caller must (a) pass `can_see_project(root_id)`, AND (b) have effective project profession ≥ **associate** on the root. The associate floor mirrors the conservative seed in `approval_policies` (t-154); paralegals + PA can see data but not extract it. m-tunable per Q2. |
+| `personal` | Any authenticated user. No additional gate. |
+
+**Profession ladder check** for project scope uses the existing `DerivationService.EffectiveProjectRole` (t-139 phase 2) — direct membership > ancestor > derived via partner-unit. Same surface that gates approvals; same surface gates extracts.
+
+**Audit row written on every export run.** A new event_type into `paliad.project_events` for project-scope (so it appears on the project's Verlauf), `partner_unit_events` for org-scope (so it appears on the partner-unit audit log of the firm-admin's home unit), and `policy_audit_log` is too narrow — we likely want a **new** audit table for org-wide actions, OR we widen `project_events` to allow `project_id = NULL` org-wide rows. **Inventor pick: new table `paliad.system_audit_log`** — clean separation, integrates into the existing 5-source AuditService union as source #6. Migration 101 adds it.
+
+`system_audit_log` columns:
+```sql
+id          uuid PRIMARY KEY DEFAULT gen_random_uuid(),
+event_type  text NOT NULL,             -- 'data_export'
+actor_id    uuid REFERENCES paliad.users(id),
+actor_email text NOT NULL,             -- captured at write time, survives user deletion
+scope       text NOT NULL,             -- 'org' | 'project' | 'personal'
+scope_root  uuid,                      -- project_id for project scope, NULL otherwise

+```
+
+The audit row is written **before** the export runs (so failed exports are still recorded) and **updated** with `file_size_bytes` + final `row_counts` on success. Failure case: separate `event_type='data_export_failed'` row with the error string in metadata. **The audit chain is the trust signal** — m sees who exfiltrated what, when, and how much.
+
+**Headers on the response:**
+- `Content-Disposition: attachment; filename="paliad-export-<scope>-<ts>.zip"`
+- `X-Paliad-Export-Audit-Id: <system_audit_log.id>` — so an automated client can reference the audit row.
+
+---
+
+## 5. Trigger model
+
+Three trigger surfaces:
+
+### 5.1 On-demand button
+
+- **Personal:** `/settings` → "Daten exportieren" card → button. POST `/api/me/export` → 200 with `Content-Type: application/zip`. Synchronous.
+- **Project:** `/projects/{id}` → settings/cog menu → "Daten dieses Projekts exportieren". POST `/api/projects/{id}/export` → 200 zip. Synchronous. Includes a "Inkl. Unterprojekte" toggle hint (it's always subtree-inclusive — the toggle is purely informational, no off switch).
+- **Org:** `/admin/data-export` (new page, card on `/admin`) → "Org-Export erstellen" button. POST `/api/admin/export/org` → **async** by default (see §6.1). Returns 202 + `job_id`. UI polls `/api/admin/export/org/jobs/{id}` for status.
+
+**Why org is async even at today's scale:** the principle isn't "is it slow now" — it's "the trigger model should not change as the firm grows." If the partner with the firm-wide button gets a different UX from the associate with the project button, we'd retrofit later. Sync at 600 rows works fine; the wrapping is `goroutine + channel + Server-Sent Events for live progress`, no new infra needed. See §6.1.
+
+### 5.2 Scheduled exports
+
+**Inventor pick — defer to slice 4.** Out of v1 scope. The reasoning: scheduling sits on storage + delivery + retention, all of which are *also* deferred to slice 3+. Building the scheduler before we know how + where the artifact lives is premature.
+
+When it lands (slice 4), the model is:
+- A new `paliad.scheduled_exports` table: `(id, scope, scope_root_id, owner_user_id, cadence, last_run_at, next_run_at, delivery)` where `delivery` is `{kind: 'email-link' | 'caldav-style-webdav', config: jsonb}`.
+- A daily cron (mai cron or a `time.Ticker` goroutine) checks `next_run_at < now()`, runs the export, posts the link via the configured delivery channel.
+- Cadence: weekly + monthly + on-status-change (e.g., "export when project closes" — a webhook from `projects.status` triggers).
+
+For now (slice 1-2), users can right-click the on-demand button and bookmark the URL — that's the **only** scheduled-export-y thing we offer, and it's intentional: get the manual flow rock-solid before adding cadence.
+
+### 5.3 API endpoint
+
+Same endpoints as §5.1, callable directly with the standard cookie / bearer auth. We don't add a separate "API key" surface in v1 — paliad doesn't have personal access tokens today. If a user wants to script their personal export weekly, they can use cookie auth from `m/paliad` automation; that's enough until power-user volume justifies a real PAT surface.
+
+For machine ergonomics: the `/api/...export` endpoints accept `?format=zip` (default), `?format=xlsx`, `?format=json`, `?format=csv-zip` query params. Only `zip` is documented; the others are internal but reachable for automation.
+
+---
+
+## 6. Storage + delivery
+
+### 6.1 Synchronous vs async — per-scope picks
+
+**Personal, project:** **Synchronous, streamed.** The handler holds the HTTP connection open, writes the zip directly to `http.ResponseWriter`. For 1MB-class exports (today's reality at every scale up to thousands of rows per entity) this is the right call — no persistence, nothing to garbage-collect, nothing leaking onto disk. Excelize's `NewStreamWriter` flushes rows as they're written so RAM stays bounded.
+
+**Org:** **Asynchronous, in-process queue, on-disk artifact.**
+- Submit (`POST /api/admin/export/org`) writes a `system_audit_log` row with status `pending` and dispatches a goroutine.
+- The goroutine writes the zip to `/var/lib/paliad/exports/{audit_id}.zip` (configurable via `PALIAD_EXPORT_DIR`; on Dokploy this is a mounted volume).
+- The goroutine updates the audit row's metadata with progress, then status `done` with `file_size_bytes` on success.
+- The user polls `GET /api/admin/export/org/jobs/{audit_id}` (SSE or simple JSON) — when ready, a download link `GET /api/admin/export/org/jobs/{audit_id}/download` serves the file.
+- Download deletes the file by default (one-shot link), or keeps it per Q3.
+
+**Why not S3-style bucket?** Paliad already has a `documents` table that *will* need a binary store, eventually. Coupling export storage to that future store is right — but the future store doesn't exist yet, and we don't want to provision MinIO on mlake purely for exports. **Inventor pick: local disk in `PALIAD_EXPORT_DIR`** until/unless we provision a real object store; at that point the export storage moves there transparently.
+
+### 6.2 Retention (Q3)
+
+**Inventor pick: 7 days, then auto-delete.** Justifications:
+1. Exports contain sensitive client data — minimising the retention window minimises blast radius if the Dokploy host is compromised.
+2. 7 days covers a holiday-week round-trip ("I exported Friday, want to look at it Monday next week, missed the day-1 link").
+3. The audit row in `system_audit_log` persists forever — you can always tell that an export happened, even after the artifact is deleted.
+
+A cleanup goroutine runs daily, lists `system_audit_log` rows older than 7 days with non-NULL `file_path`, deletes the file, sets `metadata.deleted_at`. Audit row stays.
+
+The `PALIAD_EXPORT_RETENTION_DAYS` env var is the knob (default `7`). m-tunable per firm.
+
+### 6.3 PII / GDPR
+
+This is where the design gets serious.
+
+**At-rest encryption.** Files in `PALIAD_EXPORT_DIR` are plaintext on the Dokploy volume. The volume itself is encrypted at the host layer (Hostinger VPS disk encryption). We **do not** layer additional file-level encryption on the artifact — that would require a per-user key, key escrow, key rotation, all of which is over-engineered for a 7-day-retention exfil where the link is single-use behind cookie auth. The disk encryption + 7-day TTL + audit log is the trust boundary.
+
+**In-transit encryption.** TLS via Dokploy + Traefik — paliad.de is Let's Encrypt-served. No raw HTTP path.
+
+**Download authentication.** The download link `/api/admin/export/org/jobs/{audit_id}/download` requires the same cookie auth as the submit. No public signed URLs in v1 (deferred per Q8). When we add scheduled exports + email delivery (slice 4), we'll need expiring signed URLs — that design is captured then, not now.
+
+**Data-subject requests.** A user invoking `/api/me/export` is, in effect, performing a self-serve GDPR Art. 15 data-portability request. Audit row records the request. If the firm receives a *third-party* DSR ("export the data my client Mr. Müller asked for"), a global_admin can run a project-scope export filtered to projects involving that client; this is a manual workflow we don't automate in v1 (open Q9).
+
+**Right-to-erasure.** Out of scope. Erasure is a write path; export is read-only. They share no code.
+
+**External sharing of export files.** A user who downloads an export and emails it to an external party has done so on their own authority and outside paliad's protection. We don't watermark the file (debated and rejected: watermarking introduces non-determinism, breaks diffability, and gives false security — anyone reading the zip can strip metadata). What we *do* document in the embedded `README.txt`:
+
+> Diese Datei enthält möglicherweise vertrauliche Mandantsdaten. Sie wurde
+> erzeugt am {generated_at} durch {actor_email} aus Paliad ({firm_name}).
+> Die Weitergabe an Dritte erfolgt in eigener Verantwortung des Empfängers.
+
+A simple "you broke the seal" notice is what we offer. It's a contract, not a control.
+
+**PII column deny-list.** Hard-coded in `internal/services/export_service.go`:
+- `paliad.users.password_hash` — doesn't exist, but the deny-list is the safety net if it ever does.
+- `paliad.user_caldav_config.encrypted_password` — explicit drop.
+- Any column whose name matches `(?i)secret|token|password|api[_-]?key|private[_-]?key` — caught at column-discovery time, errors loudly into `system_audit_log.metadata.warnings`.
+- `paliadin_turns.assistant_response` — present in personal export of caller's own data; **off** in org export by default (m's call per Q5).
+
+### 6.4 GDPR-completeness note
+
+The export of one user's personal scope is **a partial Art. 15 disclosure** — it contains what's *in paliad's* control. Other systems (Supabase Auth row, mlake logs, CalDAV provider) are out of paliad's scope and not in the export. The embedded README states this explicitly so the user knows the workbook is the paliad-side answer, not a complete personal-data dump from "the firm."
+
+---
+
+## 7. Slice plan
+
+Tracer-bullet shipping. Each slice is independently shippable and reviewable. The first slice closes the no-lock-in promise for the smallest, lowest-risk scope; later slices widen.
+
+### Slice 1 — personal export, synchronous, xlsx + JSON
+
+- Adds `excelize/v2` to `go.mod`.
+- New `internal/services/export_service.go` with the column-discovery + writer plumbing for xlsx + JSON.
+- New `internal/handlers/export.go` with `POST /api/me/export`.
+- New `/settings` UI: "Daten exportieren" card + button.
+- Migration 101: `paliad.system_audit_log` + `AuditService.ListEntries` 6th union branch.
+- i18n keys (`settings.export.*`, `__meta.*`).
+- Tests: `export_service_test.go` covers xlsx structure (one row each kind), JSON shape, PII deny-list.
+
+Ships the no-lock-in promise for every user immediately. ~600-800 LoC + ~25 i18n keys.
+
+### Slice 2 — project export, synchronous, xlsx + JSON + CSV-zip
+
+- Generalises the export_service to scope-aware queries (the visibility predicate gets injected per scope).
+- New `POST /api/projects/{id}/export`, gated by §4.
+- Adds CSV writer alongside xlsx + JSON; bundles all three into `.zip`.
+- Project-detail UI gets the export menu entry.
+- README.txt template embedded.
+- Tests + e2e (Playwright) on the project page button.
+
+~800-1000 LoC. The CSV path generalises the xlsx column-discovery so the marginal cost is low. After this slice, two of three scopes are shipped and synchronous serves both.
+
+### Slice 3 — org export, async with job tracking
+
+- Adds the goroutine + on-disk artifact path + `PALIAD_EXPORT_DIR` env.
+- `POST /api/admin/export/org` + job status + download endpoints.
+- New `/admin/data-export` page (card on `/admin/`).
+- Cleanup goroutine (daily, deletes artifacts > `PALIAD_EXPORT_RETENTION_DAYS`).
+- Refactor: extract the now-common "writeExportToWriter" core from the synchronous path so async re-uses it.
+
+~600-800 LoC. After this slice, all three scopes ship + audit trail is complete.
+
+### Slice 4 — scheduled exports (deferred, not v1)
+
+Designed in §5.2; building deferred until at least 2 firms ask. The contract surface is the `scheduled_exports` table + cadence + delivery channel.
+
+### Slice 5 — API ergonomics (deferred)
+
+Personal Access Tokens (the "I want to cron my own export" surface). Until there's a customer, we don't build the PAT issuer + revocation + audit.
+
+### Slice 6 — GDPR DSR helpers (deferred)
+
+A `/admin/data-subject-request` workflow to assemble a per-natural-person export across projects. Built on Slice 1-3 primitives; not blocked by them.
+
+### Slice 7 — document binary inclusion (deferred until documents have rows)
+
+When the `documents` table starts holding real files, the export adds a `documents/` subdir in the zip with the actual files, keyed by filename = `{document_id}.{ext}`. The metadata sheet links by id. Adds ~150 LoC + an env var for the file backend.
+
+**Critical-path slices for v1: 1 + 2 + 3.** Everything after is layered, optional, m-prioritised when there's a real customer pull.
+
+---
+
+## 8. Trade-offs flagged
+
+1. **xlsx-first means we own the `excelize` dependency forever.** Mitigation: excelize is the canonical Go xlsx — replacing it would be a multi-thousand-LoC migration, but the upstream is healthy (MIT, 17k+ stars, monthly releases). Acceptable lock-in.
+
+2. **Determinism (sorted file order, sorted JSON keys, row-id-ordered CSV) is implementation discipline, not a library default.** Test that breaks if any future change introduces non-determinism is essential (helps reviewers + prevents regressions).
+
+3. **Synchronous personal + project means a runaway export can block a request goroutine for seconds.** At today's data shape this is sub-second. Watchdog: a 30s context deadline on synchronous exports; over that, return 503 with "export too large — contact admin for async." Triggers slice 3 → slice 4 of the user's mental model.
+
+4. **Per-scope endpoints triplicate similar code paths.** Mitigated by the shared `ExportSpec` struct + scope-aware predicate injection. Read carefully in code review — this is the place subtle scope leaks creep in.
+
+5. **JSON twin is genuinely redundant for human users.** It's there for the no-lock-in promise (a Python script can re-ingest without Excel). The cost is one extra file in the zip + one extra serialisation pass. Acceptable.
+
+6. **No diff tooling — yet.** Determinism enables `diff -r` between two extracted zips, but no in-app surface. Slice 4+ may layer "show me what changed between Monday's and Friday's export" once exports are scheduled and stored.
+
+7. **`paliadin_turns` privacy default.** Currently restricted to `PaliadinOwnerEmail` so the table is empty for every other user. Personal export carries them by default ("your AI history"); org export by default does NOT (admin opt-in via `?include=paliadin_turns`). When Paliadin opens past owner-only (post-API cutover), revisit.
+
+8. **Reference-data inclusion bloats every export.** 254 deadline_rules + 102 trigger_events + 56 concepts + … = ~1000 reference rows in every workbook regardless of scope. At zip-compressed sizes this is < 100KB and worth the standalone-interpretability. If the workbook gets too large later, ship reference data as a separate "paliad-reference-snapshot.zip" once + reference it from each export's README.
+
+9. **Org export volume at firm-scale.** A 10k-project firm has ~50k deadlines and ~200k audit events. Even at 200 bytes/row average that's < 100MB — comfortable for the async path with 4GB Dokploy RAM. Threshold concerns kick in at 1M+ rows, which is firm-class-of-100-attorneys territory. Designed for, not blocked on.
+
+10. **Audit-log explosion.** A nightly cron + 47 users self-exporting = 50 audit rows / day. At a year that's 18k rows. Still trivial. No retention on the audit chain (the artifact retention does NOT touch audit-log retention — the audit chain is the trust signal, see §4).
+
+---
+
+## 9. Recommended implementer
+
+**Single PR, layered slices 1 → 2 → 3 as separate commits.** No DB-heavy migrations; the only schema add is `system_audit_log` (one table, one trigger if any). The hard work is in the writer abstraction.
+
+- **Slice 1:** pattern-fluent Sonnet coder. ~600-800 LoC, mostly bookkeeping. Tests pin the shape.
+- **Slice 2:** same hands as slice 1 (continuity matters here — the writer abstraction is set in slice 1 and the project scope generalises it).
+- **Slice 3:** same hands again. The async path is its own subsystem but the writer is unchanged.
+
+**NOT cronus** per memory directive 2026-05-06 (retired from paliad).
+**NOT m** — this is a coder task end-to-end.
+
+---
+
+## 10. Inventor → coder transition (GATED per project CLAUDE.md)
+
+Per `.claude/CLAUDE.md`: design phase ends here. No code touches the tree from inventor. Head's `mai-head` skill gates the coder shift after m's go on §11 open questions.
+
+When approved, the coder shift opens on `mai/<coder-name>/data-export-slice-1` (fresh branch off main, NOT off the design branch — design doc commit is the only artifact this branch carries forward via cherry-pick).
+
+---
+
+## 11. Open questions for m
+
+The brief lists 8 candidate questions. After live-state verification I've collapsed + sharpened to 9, each with an inventor pick + reasoning. Will be asked sequentially via AskUserQuestion (paliad dogma — no `## §X.Y` markdown dump on m, per t-paliad-154 lesson).
+
+### Q1 — Bundle xlsx + CSV + JSON in one zip, or let user pick format?
+
+**Inventor pick: bundle all three in one zip, no UI knob.**
+
+Reasoning: the no-lock-in promise *requires* the JSON twin (Excel-independent re-ingest); the xlsx is the human-readable default; CSV is the universal lingua franca. Picking only one breaks the promise for some user. Bundle size at today's scale is < 1MB; even at firm-scale it's well under the email-attachment limit. The cost of a checkbox UI is more than the cost of three extra files.
+
+Alternative: offer `?format=xlsx-only|json-only|csv-only` query params for the API surface, default to bundle. Documented in README only. We do this in v1 anyway since multi-format is what generates the zip in the first place.
+
+### Q2 — Project-scope profession floor: associate (inventor pick) or member?
+
+**Inventor pick: associate floor.**
+
+A project export carries party names, addresses, decision-history, draft strategy notes. That's "I can write a paper for the partner" data, not "I can see the deadline calendar" data. Member is the bare-visibility tier (you got added to the team). Export is exfiltration — needs the next tier up.
+
+Alternative: gate by `responsibility ∈ {lead, member}` (no profession floor, only the project-team responsibility check). Cleaner architecturally — separates the "can see" axis from the "can extract" axis using the same fields. Less restrictive in practice.
+
+Worth choosing now because the gate text in the audit row mentions the tier.
+
+### Q3 — Org-export artifact retention: 7 days (pick) or 30 / 90?
+
+**Inventor pick: 7 days.**
+
+Default conservative. m-tunable per firm via env var.
+
+### Q4 — Excel dates: ISO strings only (pick) or also a mirrored native-Excel-date column?
+
+**Inventor pick: ISO strings only.**
+
+Native Excel dates are locale-poisoned (DE vs EN epoch interpretation flips, round-trip corruption when re-saved). ISO is the universal answer. Power users who want a sortable native-date column can derive it once in their workbook — but the canonical export stays unambiguous.
+
+### Q5 — `paliadin_turns` in org export: opt-in only (pick), or include by default?
+
+**Inventor pick: opt-in via `?include=paliadin_turns` query.**
+
+Today it's m-only data (`PaliadinOwnerEmail` gate), so the privacy stakes are low — but the *moment* Paliadin opens beyond owner-only, the AI conversation history per user is the most sensitive personal data we carry. Setting the off-by-default precedent now means we don't accidentally start dumping it later.
+
+### Q6 — Deterministic byte-for-byte exports: yes (pick) or accept timestamp drift in zip metadata?
+
+**Inventor pick: yes, deterministic.**
+
+Lets users diff exports across time. Cost: ~50 lines of `sort.Strings` + a custom zip writer with stable ordering. Worth it.
+
+### Q7 — Invitation tokens in org export: drop them entirely (pick) or include as hash?
+
+**Inventor pick: drop entirely.**
+
+Tokens grant signup access. Including them in a backup creates a vulnerability surface — an exfiltrated backup could be used to sign up as someone-else with their pending invite. Hashing doesn't help because the hash is what the URL contains. The invitation **row** (recipient, role, expiry, sent_at) is in the export; the token is not. If you need to re-issue, you do so from paliad's invite UI.
+
+### Q8 — Public signed-URL downloads (for scheduled/email delivery): yes / not in v1 (pick)?
+
+**Inventor pick: not in v1.**
+
+Defer to slice 4. v1's download is cookie-authenticated only. Signed URLs are useful when the recipient is asynchronously notified (email link), which is the scheduled-export model — and that whole subsystem ships later.
+
+### Q9 — GDPR Art. 15 DSR helper UI: not in v1 (pick)?
+
+**Inventor pick: not in v1.**
+
+A global_admin can already assemble a DSR manually using project-scope exports filtered by client. v1 ships the primitives; v2 ships the workflow.
+
+### Closing question for m: implementer
+
+> Recommend pattern-fluent Sonnet for all three slices, same hands across (continuity matters for the writer abstraction). Specific name = your call.
+
+---
+
+## 12. m's decisions (addendum, 2026-05-19)
+
+m walked the §11 questions live via AskUserQuestion. Results below — these supersede the inventor picks where they differ.
+
+- **Q1 — Bundle format:** Bundle xlsx + JSON + CSV in one `.zip` per export. ✓ matches pick.
+- **Q2 — Project-scope floor:** **Any team member** (`responsibility ∈ {lead, member}`). ⚠ **Deviation** from associate-floor pick — m chose the looser axis-split gate. **Implementation update for §4:** project-scope auth becomes `(a) can_see_project(root_id) AND (b) caller is on project_teams for the root with responsibility ∈ {lead, member}`. The DerivationService profession check is dropped from the export gate; observers + externals + derived-only members still cannot extract. `system_audit_log.metadata` records the responsibility value the caller held at export time.
+- **Q3 — Org-export retention:** **90 days**. ⚠ **Deviation** from 7-day pick. **Implementation update for §6.2:** `PALIAD_EXPORT_RETENTION_DAYS` default flips from `7` to `90`. The cleanup goroutine still runs daily; the threshold is just longer. Audit row unaffected (still persists forever).
+- **Q4 — Date format:** ISO 8601 strings only. ✓ matches pick.
+- **Q5 — paliadin_turns in org export:** **Never include in org export.** ⚠ **Tighter** than opt-in pick. **Implementation update for §2.1 + §6.3:** the `paliadin_turns` row drops from the org-scope sheet table entirely — no `?include=paliadin_turns` query param. Personal scope still carries the caller's own paliadin_turns (it's literally their data). The hard exclusion is enforced in `export_service.go`'s scope-aware sheet registry, not just in column-discovery, so a future schema addition can't accidentally re-include it.
+- **Q6 — Deterministic exports:** Yes. ✓ matches pick. (m answered freeform "1" alongside the batching request — first option = deterministic.)
+- **Q7 — Invitation tokens:** Drop entirely. ✓ matches pick.
+- **Q8 — Signed URLs in v1:** Not in v1. ✓ matches pick.
+- **Q9 — GDPR DSR helper UI in v1:** Not in v1. ✓ matches pick.
+
+**Net effect on slice plan:** unchanged shape, three modifications:
+- Slice 2 gate logic uses `project_teams.responsibility` only (no profession lookup).
+- Slice 3 default retention is 90 days (one env-var value change).
+- Slice 1 + 3 sheet registry omits `paliadin_turns` from org scope entirely.
+
+No other slice deltas. v1 still ships slices 1+2+3.
+
+**Coder shift gating:** head still gates the implementation handoff; m's decisions here close §11 but don't auto-trigger coder work.
+
+---
+
+## 13. Adjacent / out-of-scope
+
+- **Import path** — explicitly out per brief. A round-trip "export then re-import" is appealing but is its own design (rebinding UUIDs, conflict resolution, schema_version migrations). Don't conflate.
+- **Postgres replacement** — the Excel workbook is a *backup* + *portability artifact*, not a data-model alternative. Postgres stays canonical.
+- **t-paliad-212 (leibniz, CalDAV multi-calendar):** personal export already carries the caller's caldav config (minus ciphertext). When leibniz designs multi-calendar, the personal export's `my_caldav_config` sheet becomes a list rather than a single row — handled by column-discovery automatically. No design conflict; flagged for confirmation when leibniz's design lands.
+- **t-paliad-213 (mendel, test strategy):** export service warrants pure-function tests for column discovery, deny-list, scope predicate, plus one e2e (Playwright) per scope endpoint. Slice tests pin the contract; mendel's overall strategy decides framework choice.

+# Design — Paliad Test Strategy (production-grade)
+
+**Author:** mendel (inventor)
+**Date:** 2026-05-19
+**Task:** t-paliad-213
+**Branch:** `mai/mendel/inventor-test-strategy`
+**Status:** DESIGN READY FOR REVIEW. No test files / Make targets / CI configs touched. Awaiting m go/no-go on §5 slice plan + §6 open questions before any coder shift.
+
+---
+
+## 0. TL;DR
+
+Paliad has accidental test discipline today: 59 `_test.go` files / 323 test functions in Go (≈45 % of services tested, ≈12 % of handlers tested) and 4 frontend test files for 90+ client modules (≈4 %). There is no committed end-to-end suite and no CI — every smoke pass is human-driven via the manual reports in `tests/`. The `mig 098` prod crash-loop, the `t-paliad-036` triple-bug after the German→English rename, and a long tail of UX regressions (deadline-done modal, calendar column drift) would all have been caught by a 10-test boot-and-click smoke pass.
+
+This design proposes a six-layer test pyramid with a concrete tool per layer (stdlib `testing` + bun's built-in `bun:test` + `playwright` for E2E — nothing third-party we don't already use). It pins three lessons paliad has paid for in commits:
+
+1. **No mocks at the service↔DB boundary.** Live-DB tests against a per-developer Postgres are the floor; in-memory mocks for `paliad.*` would have hidden every rename-after-DROP-CASCADE bug. Project preference is already in this direction (27/44 service tests are live-DB-gated); we double down rather than reverse.
+2. **Migrations must dry-run before they merge.** Every recent prod-down (mig 098, mig 020-after-rename, mig 099 audit_reason gap) was a migration that compiled, passed `go test ./...` (which skips without `TEST_DATABASE_URL`), and broke on first apply against the real schema. A `make verify-migrations` target that does BEGIN/apply/ROLLBACK in CI fixes the entire failure mode.
+3. **Browser-shaped bugs need a browser.** The fristenrechner cascade, shape-timeline render, calendar grid, inline paliadin widget — these are JS state machines. Bun's stdlib `bun:test` covers the pure parser/codec code; Playwright covers the auth-gated DOM. Don't try to substitute one for the other.
+
+Six slices roll the strategy out as tracer-bullet PRs, each independently shippable. Slice 1 (migration dry-run harness) and Slice 4 (Playwright golden-path smoke) buy the most outage-prevention per LoC; the rest is widening proven patterns.
+
+Six open questions for m at §6. Most surface a coverage-vs-cost trade-off — the picks that need m's call before any code lands are CI infrastructure choice (Q2), per-PR run-time budget (Q1), and live-DB-vs-dockerised Postgres (Q3).

+## 1. Audit — what exists today
+
+Counts taken on `mai/mendel/inventor-test-strategy` @ HEAD (2026-05-19, 100 migrations applied).
+
+### 1.1 Go test inventory
+
+| Package | Source files | Test files | Test functions | Notes |
+|---|---|---|---|---|
+| `internal/services` | 56 | 44 | ~200 | 26 live-DB-gated (`TEST_DATABASE_URL`), 18 pure-Go. 24 services have **no test file at all** — see §1.4. |
+| `internal/handlers` | 59 | 7 | ~30 | Only auth-domain check, search, audit-parse, approval-error-mapping, redirects, verfahrensablauf-redirect, chart-404 covered. **53 handlers have no test file.** |
+| `internal/auth` | small | 2 | ~10 | Session middleware + require-admin. |
+| `internal/branding` | small | 1 | small | Firm-name override. |
+| `internal/offices` | small | 1 | small | Office enum. |
+| `internal/changelog` | small | 1 | small | Pure parser. |
+| `internal/calc` | small | 1 | small | Fees / fee tables. |
+| `cmd/server` | 1 | 1 | small | `main_paliadin_backend_test.go` covers env-gate selection. |
+| **Total** | **133** | **58** | **323** | |
+
+`go test ./...` runs all 58 files. Without `TEST_DATABASE_URL` set, 27 of them silently skip their live-DB cases — the suite still passes, but coverage of mutation paths drops to near zero.
+
+### 1.2 Frontend test inventory
+
+| Path | Test files | Tested |
+|---|---|---|
+| `frontend/src/client/filter-bar/url-codec.test.ts` | 1 | FilterBar URL codec round-trip. |
+| `frontend/src/client/views/format.test.ts` | 1 | Date/time formatters (regression for t-paliad-153). |
+| `frontend/src/client/views/shape-timeline-chart.test.ts` | 1 | Chart layout pure function. |
+| `frontend/src/client/views/shape-timeline-cv.test.ts` | 1 | Continuous-view shape layout. |
+| **Total** | **4** | Out of ~90 client modules (`frontend/src/client/*.ts`). |
+
+All four use bun's built-in `bun:test` (no extra dep). No DOM/jsdom tests. No Playwright. No `bun test` script in `package.json` (`bun run build` is the only script).
+
+### 1.3 End-to-end / smoke
+
+- `tests/smoke-2026-04-25.md`, `tests/smoke-auth-2026-04-25.md`, `tests/smoke-auth-2026-04-26-cleanup.md` — human-written reports with screenshots committed under `tests/screenshots-*`. No code. No re-runnable script.
+- `mai-tester` skill uses Playwright for ad-hoc runs; nothing committed.
+- No `e2e/`, no `.gitea/workflows/`, no `.github/workflows/`, no `Makefile`.
+
+### 1.4 Critical service paths with no test file
+
+These are `internal/services/*.go` for which no `*_test.go` sibling exists:
+
+| Service | Risk class | Why it matters |
+|---|---|---|
+| `caldav_service.go`, `caldav_client.go`, `caldav_crypto.go`, `caldav_ical.go` | High | Per-user push/pull goroutines + AES-GCM at rest. One pure parser test (`caldav_ical_timeline_test.go`) exists but the service + crypto + WebDAV client are blind. |
+| `agenda_service.go` | High | Dashboard agenda query; reused by `/agenda` page. Exercised transitively by visibility tests but no direct test. |
+| `dashboard_service.go` | High | Traffic-light + summary counts. Same story — transitively covered via visibility, no direct test. |
+| `derivation_service.go` | Medium | Project-tree derivation (the new t-paliad-194-era subtree machinery). |
+| `team_service.go` | Medium | Team membership / inheritance. |
+| `partner_unit_service.go` | Medium | Dezernat replacement (t-paliad-070). |
+| `party_service.go`, `note_service.go`, `link_service.go`, `checklist_instance_service.go` | Medium | All do project-scoped CRUD with the same RLS+audit pattern that `t-paliad-036` proved easy to break. |
+| `appointment_service.go` | High | Hot — every calendar mutation. Exercised through approval tests but has no own test file. |
+| `view_service.go` | Medium | Powers the substrate (`/views/*`). |
+| `paliadin_jwt.go` | Medium | Per-turn JWT mint for the aichat path (`t-paliad-194`). No call sites in tests today. |
+| `markdown.go` | Low | Glossary + checklist content render. |
+
+### 1.5 Handlers with no test file
+
+53 of 59. Notably: **`auth.go` itself** (login / logout / session creation), **`projects.go`** (the most-mutated entity), **`deadlines.go` / `appointments.go`** (writes), **`paliadin.go` / `paliadin_suggest.go`** (m-only routes — never click-tested), **`fristenrechner.go` / `fristenrechner_search.go` / `fristenrechner_event_categories.go`** (the cascade users live in), **`dashboard.go` / `agenda.go`** (landing), **`onboarding.go` / `onboarding_gate.go`** (every new user's first three minutes), **`invite.go`** (rate-limited write path). The currently-tested handlers (search, audit-parse, approval error mapping, etc.) are the cheap pure-Go ones; every handler that touches the DB is untested at handler level.
+
+### 1.6 Live-DB test scaffold — is it sound?
+
+The pattern (read from `internal/services/visibility_test.go`):
+
+```go
+url := os.Getenv("TEST_DATABASE_URL")
+if url == "" { t.Skip("TEST_DATABASE_URL not set — skipping live DB test") }
+if err := db.ApplyMigrations(url); err != nil { t.Fatalf(...) }
+pool, _ := sqlx.Connect("postgres", url)
+defer pool.Close()
+// per-test seed + cleanup via DELETE + defer cleanup()
+```
+
+Verdict: **sound, but has rough edges that need addressing before we widen.**
+
+- ✅ Migrations apply at test startup against the test DB — catches every "you forgot to add a CHECK" / "you reference a column that doesn't exist" before a real-DB-touching test runs.
+- ✅ Per-test cleanup via `DELETE FROM ... WHERE id IN ($1,...)` is explicit and idempotent.
+- ✅ The `paliad.paliad_schema_migrations` tracker collision noted in memory `0b900afa…` is a pre-existing issue, not introduced by this design.
+- ⚠️ Cleanup-via-DELETE is fragile: a test that creates a row referenced by FK from another table needs to remember to clean both. A few existing tests (see `audit_service_test.go`) already chain 5+ DELETEs.
+- ⚠️ Tests can't run in parallel against the same `TEST_DATABASE_URL` because they share schema state. `go test ./...` defaults to `-parallel` per-package; same-package tests with overlapping cleanup IDs can interfere.
+- ⚠️ No CI today actually exercises `TEST_DATABASE_URL` — so every live-DB test is effectively run only on the author's laptop or not at all. Half the value is paid-for but unbilled.
+
+### 1.7 Migration tooling
+
+- `internal/db/migrate.go` embeds `migrations/*.sql` and applies on server boot via `golang-migrate/v4` with the `paliad_schema_migrations` tracker in `public` schema.
+- 100 migrations on disk (`001` → `100`).
+- **No dry-run gate today.** A bad migration breaks `paliad.de` at boot (Dokploy crash-loops the container). Recent prod incidents: mig 098 (submission code rename), mig 099 (with_po flag drop missed audit_reason gap), mig 020 (function rename without body rewrite — see memory `49a05cfa…`).
+- `down.sql` exists for every migration but no test ever exercises it.
+
+### 1.8 CI / deploy loop
+
+- No CI. Push-to-main → Gitea webhook → Dokploy auto-builds the Dockerfile and replaces the container. The Dockerfile runs `bun run build` then `go build`. **Neither `go test` nor `bun test` runs in the build pipeline.**
+- Pre-commit hooks: none in repo. Each worker runs `go build / go vet / go test / bun run build` by convention (see memories — every shipped task report ends with "build hygiene held").

+```
+
+### Layer 0 — Migration dry-run
+
+**What:** Every `*.up.sql` in `internal/db/migrations/` is applied inside a single `BEGIN ... ROLLBACK` transaction against a scratch Postgres, in numeric order. The harness asserts each statement succeeds *and* asserts no statement leaves the schema in a `paliad_schema_migrations.dirty=true` state. A second pass applies all up-migrations end-to-end (no rollback) and then re-applies the latest up-migration to assert idempotency (every paliad migration since `t-paliad-070` has been written to be idempotent — this enforces it).
+
+**Tool:** stdlib `testing` package, no third-party. Pattern: `internal/db/migrate_test.go` with a `TestMigrations_DryRun` driven from `TEST_DATABASE_URL`. A `make verify-migrations` target wraps it.
+
+**Why this layer matters most:** Every recent prod-down was a migration. Catching them on a CI run before merge is the highest-leverage test investment paliad can make. Cost: one ~100-line Go file + one Postgres in CI.
+
+**Coverage target:** 100 % of `*.up.sql` files. Hard gate on PR — no exceptions.
+
+### Layer 1 — Go unit (pure)
+
+**What:** `go test ./...` against pure functions — formatters, parsers, validators, calculators, fee tables, deadline calculators, projection lookahead clamping, codec round-trips. No DB, no HTTP.
+
+**Tool:** stdlib `testing`. Table-driven `cases := []struct{...}{...}` style is already the house pattern (see `auth_test.go` / `projection_anchor_test.go`). **Do not introduce testify or any matcher library** — the current code reads cleanly without one, and 323 existing test functions don't need a rename pass.
+
+**What's already there:** 19 pure-Go test files (calculator, mapping, codec, holiday, fees, etc.). Density is good; targeted infill rather than re-architecture.
+
+**Coverage target:** Every pure function in `internal/services/`, `internal/handlers/`, `internal/calc/`, `internal/changelog/`. Aim for "every branch in a decision table has at least one test row." Don't chase % — chase "the obvious edge that would burn a coworker".
+
+### Layer 2 — Frontend unit (pure)
+
+**What:** `bun test` against pure TS modules — URL codecs (`filter-bar/url-codec`), formatters, parsers, i18n key correctness (every `data-i18n` attribute used in TSX has a key in `i18n.ts`), view-spec parsers, projection-row mapping helpers.
+
+**Tool:** `bun:test` (built into bun, no install). Already in use in 4 files — extend the same pattern. Add `bun test` to `package.json` `scripts`.
+
+**What to add:**
+- i18n key audit (every `t("foo.bar")` and `data-i18n="foo.bar"` resolves in both `de` and `en`).
+- `filter-bar/` types + render helpers (paliad has shipped 4 FilterBar slices; coverage is one codec test).
+- `paliadin-context.ts` route table + entity extraction (the `[ctx …]` envelope is a stable contract paliadin's SKILL.md depends on; any drift here is a silent failure).
+- `paliadin-starters.ts` registry — every route maps to ≥1 starter; every starter is bilingual.
+- View-spec parsers in `views/`.
+
+**Coverage target:** Every pure TS module in `frontend/src/client/`. Pages (TSX renderers) are E2E concern, not unit concern.
+
+### Layer 3 — Frontend DOM (cascade / jsdom)
+
+**What:** `bun test` with jsdom global, exercising the interactive cascade modules — the fristenrechner cascade builder, the shape-timeline render, the FilterBar UI (chips, panels), the calendar grid, the inline Paliadin widget message stream, the inbox-row click handler, the dashboard activity item navigation.
+
+These modules contain enough state that pure-function tests miss real bugs (e.g. the t-paliad-098 `.entity-table` row-cursor lie was a CSS+DOM bug; t-paliad-099's modal close was a DOM-event bug; t-paliad-103's `::before` overlay click-swallow was a DOM bug).
+
+**Tool:** bun + `happy-dom` is the lighter choice; if it can't handle event ordering, fall back to `jsdom`. Both are ESM-clean and bun-friendly. **Pick one and stick with it — running both means twice the dependency surface.** Default pick: `happy-dom` (smaller, paliad doesn't need legacy IE semantics).
+
+**Pattern:** import the cascade module, build a minimal DOM (`document.body.innerHTML = …`), dispatch synthetic events, assert resulting state. Reuses the production renderers — no test-only fakes.
+
+**Coverage target:** ~15 modules. Specifically:
+- `client/filter-bar/index.ts` chip render + active-state.
+- `client/fristenrechner.ts` cascade — most complex JS in the codebase; depend chains light up every UPC bug we know.
+- `client/shape-timeline.ts` lane mode + track mode (envelope wire shape brittle to refactor).
+- `client/projects-detail.ts` row click + Verlauf render.
+- `client/paliadin-widget.ts` + `paliadin-context.ts` interaction.
+- `client/inbox.ts` row-action click routing.
+- `client/dashboard.ts` activity-item nav.
+- `client/deadlines-calendar.ts` / `appointments-calendar.ts` column layout (the calendar-column-drift bug class).
+
+Not unit tests; not E2E. They are the missing middle.
+
+### Layer 4 — Service-layer (live DB)
+
+**What:** Go service methods against a real Postgres, using the existing `TEST_DATABASE_URL` pattern. Two improvements:
+
+1. **Replace per-test DELETE cleanup with a per-test transaction harness** — open a transaction, run the test inside it, ROLLBACK. Faster, isolating, no cleanup forgotten. Already viable because the service layer accepts `*sqlx.DB`-or-tx-shaped interfaces in many places; needs a small `internal/services/internal/testdb` package that exposes `WithTx(t *testing.T, fn func(*sqlx.Tx))`. Migration is mechanical, can happen alongside infill.
+
+   *Caveat:* some service methods open their own transactions internally (`approval_service.submit` is one). Those keep DELETE cleanup; the tx harness is a default, not a mandate.
+
+2. **Make `TEST_DATABASE_URL` mandatory in CI.** Today these tests are skipped on every machine that doesn't `export TEST_DATABASE_URL=…` — i.e. they don't run on autoatic pipelines because there's no pipeline. Once CI exists (§3.5), it becomes a required env var.
+
+**Tool:** stdlib `testing` + `sqlx` (already in `go.mod`). **No mocks at the service↔DB boundary.** This is m's hardest line — see global CLAUDE.md memory pattern and `t-paliad-036` (the bug that masked two other bugs would have been caught instantly by a real-DB test).
+
+**Where to invest first:** Approval (already heavy), Projection (already heavy), Fristenrechner (already heavy), DeadlineService Create/Update/Complete/Delete with `pending_request_id` interplay, AppointmentService same, ProjectService visibility predicate, CalDAV push (the four CalDAV `*.go` files have zero direct test).
+
+**Coverage target:** Every service method that mutates the DB has at least one happy-path live-DB test. RLS predicate (`visibilityPredicatePositional`) has one test per role (global_admin, member, non-member).
+
+### Layer 5 — Handler integration (httptest + real DB)
+
+**What:** Spin a real `services.DBService`, mount the protected mux, drive `httptest.NewRequest` + `ServeHTTP` against it. Auth via a fake session cookie produced by a `testauth.Login(t, userID)` helper that mints the same Supabase JWT shape `auth.UserIDFromContext` expects.
+
+**Why:** The 53 untested handlers are where the request shape ↔ service interaction lives. Examples that would have caught real bugs:
+- `t-paliad-036`'s "`/projects/{id}` 404 while `/api/projects/{id}` 200" mismatch — a 5-line handler test would have failed before the migration ran.
+- mig 020's three-stacked bug — a handler test that POSTs a deadline and asserts a 200 + read-back row would have failed at submit-time, not boot-time.
+- The audit-log query timezone bug — handler test asserts the JSON contains the expected `event_date`.
+
+**Tool:** stdlib `net/http/httptest`. **No new framework.** Pattern: handler tests live next to the handler file (`internal/handlers/deadlines_test.go` next to `deadlines.go`).
+
+**Coverage target:** Every handler that gates a state-changing route — `POST/PATCH/DELETE` flavour. Plus `GET` handlers that compose a non-trivial query (dashboard, agenda, search, audit-log).
+
+### Layer 6 — End-to-end (Playwright)
+
+**What:** A small Playwright suite (~10 flows) committed at `e2e/` with a `bun run e2e` entry. Targets a local `./paliad` against a scratch Postgres (the same `TEST_DATABASE_URL`). Each test logs in, drives the UI through one user journey, asserts visible state.
+
+**Why ~10 not 100:** Per-PR budget caps at ~2 min total (§6 Q1). Playwright tests are the most expensive minute-per-confidence in this stack; they pay for themselves on the *golden path* and nothing else. The deep-coverage layer is L5; E2E is *"is the app still alive end to end?"*.
+
+**Tool:** `playwright` (npm; bun installs cleanly). No third-party test runner — Playwright ships its own. Tests live in `e2e/*.spec.ts`. **Not bun:test.** Playwright's runner is purpose-built for browser-driving and integrates with their tracing — don't fight it.
+
+**Cap:** 10 flows. If a new test wants in, an existing one must drop out (or we have a real reason to widen). This is the cheapest discipline available: it forces the suite to remain a smoke pass, not a regression-test dumping ground.
+
+**Coverage target:** See §4.
+

+
+## 3. Tooling — concrete picks per layer
+
+| Layer | Tool | Already in deps? | Install? |
+|---|---|---|---|
+| L0 — migration dry-run | stdlib `testing` + `migrate/v4` | yes | no |
+| L1 — Go unit | stdlib `testing` | yes | no |
+| L2 — Frontend unit | `bun:test` | yes (built into bun) | no |
+| L3 — Frontend DOM | `bun:test` + `happy-dom` | bun yes, happy-dom **new** | `bun add -d happy-dom` (one dep, ~200 KB) |
+| L4 — Service live-DB | stdlib + sqlx | yes | no |
+| L5 — Handler integration | stdlib `net/http/httptest` + sqlx | yes | no |
+| L6 — E2E | `@playwright/test` | **new** | `bun add -d @playwright/test` + `npx playwright install chromium` |
+
+Net new deps: **2** (happy-dom + playwright). Both are mainstream, both have small surface area, both align with bun's ecosystem.
+
+Explicit rejects:
+- ❌ **testify** — current tests read cleanly with stdlib; adding it forces a rename pass nobody wants.
+- ❌ **vitest** — bun's built-in test runner is faster and the tests are already in `bun:test` shape.
+- ❌ **dockertest / testcontainers-go** — m's preference is real-DB tests against the existing Postgres; spinning ephemeral Docker Postgres per package run adds latency and surface area for marginal isolation gain. See Q3.
+- ❌ **sqlmock / gomock for DB** — banned by §0 lesson 1.
+- ❌ **cypress** — Playwright is the better tool today, and the team's existing skill (`/mai-tester`) already uses it.
+
+### 3.1 Per-PR run-time budget
+
+Target (subject to m's call in Q1): **≤ 90 s for the gating tier (L0+L1+L2+L4 subset+L5 happy-path)**, ≤ 4 min for the full suite (add L3+L4 full+L6). The gating tier blocks merge; the full suite blocks deploy.
+
+Indicative times (estimated, validate when slice 1 lands):
+
+| Tier | Layers | Est. time | Blocks |
+|---|---|---|---|
+| **Gate (every PR)** | L0 + L1 + L2 + L5 happy-path + L4 critical | 60–90 s | merge |
+| **Full (every merge to main)** | + L4 full + L3 + L6 | 3–4 min | deploy |
+
+### 3.2 CI — proposal, not commitment
+
+paliad has no CI today. Two routes:
+
+- **Gitea Actions** (m's stack already runs `mgit.msbls.de`). Self-hosted; same auth model as the rest of mAi. Adds a `.gitea/workflows/test.yml`. Postgres comes from a service container.
+- **Stay click-deploy.** No CI. Workers run tests locally; Dokploy auto-deploys on green-main convention.
+
+Recommendation: **Gitea Actions for the gate tier only** (L0 + L1 + L2), driven by a single short workflow. The L3-L6 expansion can be a follow-up once the gate tier proves stable. Deferred to Q2 for m's call.
+
+### 3.3 Test DB — live YouPC vs ephemeral
+
+The `paliad` schema lives on the shared YouPC Postgres (port 11833). Three options:
+
+| Option | Pros | Cons |
+|---|---|---|
+| **Per-developer separate DB on YouPC** (`TEST_DATABASE_URL` per laptop) | Closest to prod; existing pattern. | Cleanup discipline matters; cross-developer contention possible. |
+| **Ephemeral docker postgres per CI run** | Full isolation; parallel-safe; reset for free. | New infra; ~5 s container startup per CI invocation. |
+| **Dedicated test DB on a paliad-only Postgres** | Isolated; cheap. | New infra to maintain. |
+
+Recommendation: **option 1 for developers (no-op change), option 2 for CI** (Gitea Actions postgres service container). Deferred to Q3 for m's call.
+
+### 3.4 Coverage targets
+
+Don't gate on percentage. Gate on critical-path coverage (§4). Add `go test -coverprofile=` output to CI for visibility, not as a merge gate. Coverage % gating produces tests-for-tests'-sake; we want the tests that catch the bugs we've shipped.
+
+---
+
+## 4. Critical journeys — what MUST be covered
+
+These are the golden-path flows. Anything not on this list is L1-L5 territory, not L6. The list is intentionally short; if it grows beyond 10, we are doing E2E wrong.
+
+| # | Flow | Why it's critical | Layer mix |
+|---|---|---|---|
+| 1 | **Login → dashboard renders → traffic-light counts match** | Every user does this every day; broken auth = paliad is offline. | L6 (Playwright) + L5 handler (auth.go) |
+| 2 | **Create project (Client → Litigation → Patent → Case)** | Hierarchy with team inheritance — the data model's spine. | L6 + L5 + L4 (project_service) |
+| 3 | **Submit deadline → routes to /inbox → approver approves → state flips** | The 4-eye flow (t-paliad-138). Most-mutated paliad surface. | L6 + L5 (deadlines, approvals) + L4 (approval_service) |
+| 4 | **Fristenrechner: pick proceeding → cascade fires → result shows** | The platform's flagship interactive tool. JS cascade. | L6 + L3 (fristenrechner cascade) + L4 (fristenrechner) |
+| 5 | **SmartTimeline: anchor a projected row → predecessor-missing-error handled** | Recent Slice-2 work (t-paliad-173 / #31). High-touch surface. | L6 + L3 (shape-timeline) + L4 (projection_service) |
+| 6 | **CalDAV sync: PUT a Termin → external client sees it, edits there → pull reconciles** | Owned-event semantics + foreign-UID skip rule from Phase F. Untested today. | L4 (caldav_service push/pull) — gated on Q3 (live YouPC vs ephemeral) |
+| 7 | **Paliadin chat: anon visit hits 404; m's session opens widget; turn renders** | Owner-gated `/paliadin` is the only m-only surface. Quiet failures here are silent. | L6 (smoke) + L5 (paliadin_suggest) + L4 (paliadin / aichat_paliadin) |
+| 8 | **/admin/rules: filter → edit one rule → lifecycle transition → audit log row** | Rules drive the cascade; bad edits break every user's fristenrechner. | L6 + L5 (admin_rules) + L4 (rule_editor_service) |
+| 9 | **Onboarding: new user with allowed email → onboarding form → first project membership** | The new-user funnel; gateOnboarded middleware traps. | L6 + L5 (onboarding, invite) |
+| 10 | **Migration boot smoke: spin paliad against an empty DB → server binds 8080** | Catches every mig-N crash-loop. | L0 (migration dry-run) + L4 boot-smoke variant |
+
+Picks 1, 3, 4 and 10 are the highest-value-per-cost — they cover the routes most regressions land on (auth, mutation, cascade, boot).

+
+## 5. Slice plan — tracer-bullet roll-out
+
+Each slice is a shippable PR with a concrete deliverable, in order of expected outage-prevention payoff. Sized for a single coder shift unless flagged. No slice depends on a later one being merged. Hour estimates intentionally omitted (per global CLAUDE.md).
+
+### Slice 1 — Migration dry-run harness + boot smoke (highest leverage)
+
+**Branch:** `mai/<coder>/test-strategy-slice-1-migrations`
+
+**Deliverable:**
+- `internal/db/migrate_test.go` — `TestMigrations_DryRun` (per-mig BEGIN/ROLLBACK), `TestMigrations_EndToEnd` (full apply, then re-apply latest to assert idempotency), `TestMigrations_Down` (apply N→0).
+- `Makefile` with `make verify-migrations` (the gate target), `make test` (run everything), `make test-go`, `make test-frontend`.
+- `cmd/server/main_paliadin_backend_test.go` already exists; extend with a `TestMain_BindsHTTPAfterMigrate` that boots the full server against `TEST_DATABASE_URL`, asserts `:8080` is listening, then shuts down. Catches the mig-098-class crash-loop in a single test.
+- README section: how to set `TEST_DATABASE_URL` locally.
+
+**Catches:** Every mig-98-class crash-loop; every drop-cascade-with-stale-policy-name regression (t-paliad-036).
+
+### Slice 2 — Service-layer infill: critical mutators
+
+**Branch:** `mai/<coder>/test-strategy-slice-2-services`
+
+**Deliverable:**
+- Test files for the three highest-impact untested services:
+  - `internal/services/agenda_service_test.go` (live-DB, dashboard agenda query)
+  - `internal/services/dashboard_service_test.go` (traffic-light counts)
+  - `internal/services/team_service_test.go` (membership + inheritance — RLS-load-bearing)
+- Tighten existing `approval_service_test.go` + `deadline_service_test.go` coverage of the create/update/complete/delete × pending-request matrix where there are demonstrable gaps.
+- Add `internal/services/internal/testdb/withtx.go` — the per-test tx harness (optional adoption; existing tests stay).
+
+**Catches:** RLS regressions, approval interplay regressions, dashboard count drift after schema renames.
+
+### Slice 3 — Frontend bun:test setup + L2 infill
+
+**Branch:** `mai/<coder>/test-strategy-slice-3-frontend-unit`
+
+**Deliverable:**
+- `frontend/package.json` `scripts.test = "bun test"`.
+- New tests under `frontend/src/client/`:
+  - `paliadin-context.test.ts` (route table, entity extraction, selection truncation).
+  - `paliadin-starters.test.ts` (every route ≥1 starter, every starter bilingual).
+  - `filter-bar/index.test.ts` (chip render + active state — pure DOM-less helpers).
+  - i18n key audit: `frontend/scripts/i18n-audit.test.ts` parses every `data-i18n="…"` from `dist/` HTML and every `t("…")` call from `src/`, asserts both `de` and `en` resolve. Runs as part of `bun test`.
+- `make test-frontend` wires `cd frontend && bun test`.
+
+**Catches:** i18n drift (untranslated key shipped to user), context-envelope contract drift (paliadin SKILL.md depends on it), starter-registry regressions.
+
+### Slice 4 — Playwright golden-path smoke
+
+**Branch:** `mai/<coder>/test-strategy-slice-4-e2e`
+
+**Deliverable:**
+- `e2e/` directory at repo root.
+- `playwright.config.ts` pointing at `http://localhost:8080` (paliad started by the test, not assumed).
+- Five Playwright `*.spec.ts` files covering critical journeys 1, 3, 4, 7, 9 from §4.
+- `make e2e` target that:
+  1. starts paliad against `TEST_DATABASE_URL`,
+  2. waits for `:8080` to be live,
+  3. runs `npx playwright test`,
+  4. tears the server down.
+- `bun add -d @playwright/test` + `npx playwright install chromium`.
+
+**Catches:** Auth regressions, deadline-mutation regressions, fristenrechner cascade regressions, owner-gated /paliadin leaks, onboarding-gate misbehaviour.
+
+### Slice 5 — Handler integration tests for the 5 most-touched routes
+
+**Branch:** `mai/<coder>/test-strategy-slice-5-handlers`
+
+**Deliverable:**
+- `internal/handlers/auth_test.go` extended with `TestLogin_HappyPath` + `TestLogout_ClearsCookie` (real DB).
+- `internal/handlers/projects_test.go` — `TestProjectsCreate` (POST 200, row inserted, audit emitted), `TestProjectsGetByID_RespectsVisibility` (404 for non-member).
+- `internal/handlers/deadlines_test.go` — `TestDeadlinesCreate_TriggersApproval` (verifies pending pill).
+- `internal/handlers/appointments_test.go` — same shape.
+- `internal/handlers/paliadin_test.go` — `TestPaliadinPage_404ForNonOwner`, `TestPaliadinPage_200ForOwner`.
+- Shared `internal/handlers/testauth/testauth.go` — mints a session cookie for `userID` so handler tests don't reinvent auth seeding.
+
+**Catches:** Handler ↔ service wiring drift, visibility-predicate handler-side bugs (t-paliad-036 bug 2 was exactly this), owner-gate bypass.
+
+### Slice 6 — Frontend L3 (DOM) cascade tests
+
+**Branch:** `mai/<coder>/test-strategy-slice-6-frontend-dom`
+
+**Deliverable:**
+- `bun add -d happy-dom`.
+- DOM-driven tests for the three most-touched cascades:
+  - `client/fristenrechner.test.ts` (cascade activate → row appears → date-set fires fetch).
+  - `client/shape-timeline.test.ts` (lane render, track render, projected-row click).
+  - `client/filter-bar/index.test.ts` (chip click toggles state, URL params update).
+
+**Catches:** The whole class of "the function exists and is unit-tested but the cascade in the browser doesn't fire it" bugs. This is the layer that catches t-paliad-098 / 099 / 102 / 103.
+
+### Slice 7 — CI wiring (deferred — Q2 dependent)
+
+**Branch:** `mai/<coder>/test-strategy-slice-7-ci` (gated on m's Q2 pick)
+
+**Deliverable:**
+- `.gitea/workflows/test.yml` (or stay click-deploy if m picks that).
+- Gate tier runs on every PR; full suite runs on merge to main.
+- Postgres service container provides `TEST_DATABASE_URL`.
+- Slack/Gotify ping on red main.
+
+**Catches:** Drift between "tests pass on my laptop" and prod reality.
+
+### Slice 8 — Coverage reporting + dashboard (lowest priority)
+
+**Branch:** `mai/<coder>/test-strategy-slice-8-coverage`
+
+**Deliverable:**
+- `go test -coverprofile=` aggregated into a single `coverage.html`.
+- Bun's coverage output similarly.
+- A `docs/coverage.md` index updated by CI.
+- **Not a merge gate.** Visibility only.
+
+**Catches:** Slow drift; nice-to-have once the floor is in.
+
+### Slice order rationale
+
+1, 4, 5 are the highest outage-prevention per LoC: migration dry-run kills crash-loops, E2E kills regressions, handler tests kill wiring drift. 2, 3, 6 widen the floor; 7-8 are infrastructure.
+
+---
+
+## 6. Open questions for m
+
+These need m's call before any coder shift starts (or before specific slices start, where noted).
+
+### Q1 — Per-PR test-run budget
+
+How long is acceptable to wait on the gate tier before merge?
+
+- 30 s — only L0 + L1 (no L2+ on the gate).
+- **60–90 s (recommended)** — L0 + L1 + L2 + L5 happy-path + L4 critical.
+- 2 min — add L3 + L4 full.
+- 4+ min — add L6 (E2E on gate).
+
+The pick determines whether E2E gates merge or only deploy.
+
+### Q2 — CI infrastructure
+
+- **Gitea Actions** (self-hosted, gate tier only, recommended) — minimal new infra; aligns with m's existing stack.
+- **Stay click-deploy** — workers run tests locally; merge discipline enforced by convention. Today's reality; we keep it.
+- **Both:** start with click-deploy, add Gitea Actions in Slice 7 once gate tier proves stable.
+
+### Q3 — Live-DB vs ephemeral docker Postgres for tests
+
+- **Per-developer YouPC DB (current pattern)** — closest to prod; existing tests work unchanged.
+- **Ephemeral docker postgres in CI, YouPC for devs (recommended hybrid)** — keeps local-dev simple, gives CI deterministic isolation.
+- **YouPC everywhere** — simplest, but parallel CI runs would contend.
+
+### Q4 — Coverage targets — % or critical-path?
+
+- **Critical-path only (recommended)** — §4's 10 flows + every state-mutating service method has a test. No % gate.
+- **% gate** — set a floor (e.g. 60 % lines, 50 % branches) and refuse merges below it.
+- **Both** — critical-path is mandatory, % is informational.
+
+m's prior preference (memory pattern: "tests that catch real bugs > coverage theatre") points at critical-path-only. Confirming.
+
+### Q5 — Which slices land before paliad is "production-grade"?
+
+paliad is already live at `paliad.de` and being used by HLC colleagues. "Production-grade" here means "next time someone ships, we don't go down."
+
+Picks:
+- **Slices 1 + 4 + 5 are the production-grade floor (recommended).** Migration dry-run + golden-path E2E + handler integration tests cover the failure modes that hit prod since the rebrand.
+- Add Slice 2 + 3 + 6 as widening passes, on their own cadence.
+- Slice 7-8 are nice-to-haves.
+
+Confirming the floor pick — and whether m wants all three to land before any new feature work, or whether they roll out alongside.
+
+### Q6 — Who owns each slice?
+
+Recommendation: rotate coder slots so the same person isn't on every slice. Suggested assignment (head can override):
+
+| Slice | Profile fit |
+|---|---|
+| 1 — migrations | Backend-heavy coder (knuth, gauss, cronus). |
+| 2 — service infill | Backend-heavy coder; whoever owns approval/projection. |
+| 3 — frontend unit | Frontend-heavy coder. |
+| 4 — Playwright E2E | Cross-stack coder; ideally one familiar with `/mai-tester`. |
+| 5 — handler integration | Backend coder. |
+| 6 — frontend DOM | Frontend coder (same person as 3 makes sense). |
+
+Inventor does **not** decide assignments; head + m do.
+
+---
+
+## 7. Out of scope (explicit)
+
+- **No rewrite of any existing test.** The 323 existing test functions stay. New tests use the new patterns; old tests are migrated only when their files are touched for unrelated reasons.
+- **No third-party framework where stdlib + bun:test suffice** (testify, vitest, etc. — see §3).
+- **No mocks at the service↔DB boundary.** This is the lock-in. Mocks lie; the live-DB tests we already have are paliad's most useful safety net.
+- **No new feature work in this strategy.** The doc proposes infra; feature scope is unchanged.
+- **No retirement of the `tests/smoke-*.md` human-written reports.** Those are great for one-shot regression hunts; they coexist with the automated suite.
+
+---
+
+## 8. Implementation notes for the eventual coder
+
+(For whichever coder picks up a slice. Not exhaustive.)
+
+- **Test-name collisions in Go's flat package namespace bite when a service grows N implementations.** Memory note from `t-paliad-194` already records this. Prefix tests with the service name (e.g. `TestAichatPaliadin_RunTurn_…` not `TestRunTurn_…`).
+- **`httptest.NewRequest` does not URL-encode** — use `url.QueryEscape` for any `?q=…` argument. Memory note from `t-paliad-026`.
+- **sqlx v1.4.0 `Named` parser strips one colon from `::uuid[]`** — known pitfall, repro lives at `internal/services/project_service.go`. Use `CAST(... AS uuid[])` in new query strings.
+- **Live-DB cleanup must DELETE FKs first.** Order matters (auth.users last). Look at `audit_service_test.go` for the chain pattern.
+- **`paliad.paliad_schema_migrations` tracker collision** is documented but unresolved. Slice 1 should add a `make reset-test-db` target that drops both `public.paliad_schema_migrations` *and* `paliad.paliad_schema_migrations` to keep developers unblocked.
+- **`bun:test` matchers are Jest-compatible** — `expect().toEqual()`, `expect().toHaveBeenCalled()`, etc. No deps needed.
+- **happy-dom does not implement** every DOM method (notably some `<dialog>` semantics). If a cascade test fails on something missing, jsdom is the escape hatch.

+## 9. Decision summary — pick list for m
+
+| # | Question | Inventor recommends |
+|---|---|---|
+| Q1 | Per-PR budget | 60–90 s gate, 3–4 min full |
+| Q2 | CI infra | Gitea Actions, gate tier only |
+| Q3 | Test DB | YouPC for devs, ephemeral docker for CI |
+| Q4 | Coverage target | Critical-path only, no % gate |
+| Q5 | Production-grade floor | Slices 1 + 4 + 5 before new feature work |
+| Q6 | Slice ownership | Rotate per profile; head decides |
+
+If m's calls match inventor's, the implementer's brief writes itself: Slice 1 first, then 4 + 5 in parallel, then 2/3/6 as widening passes.
+
+---
+
+**Status:** DESIGN READY FOR REVIEW. Awaiting m go/no-go on §5 slice plan + §6 open questions before any coder shift starts.
+
+---
+
+## 10. m's decisions (2026-05-19, locked)
+
+Walked through §6 with m via the AskUserQuestion interview (per head's 2026-05-19 workflow rule: inventor questions are resolved before parking, not after). Six picks locked, all matching inventor's recommendation.
+
+| # | Question | m's answer | Effect on plan |
+|---|---|---|---|
+| Q1 | Per-PR test-run budget | **Inventor's call** (m deferred). Pick: **60–90 s gate, 3–4 min full.** | Gate tier = L0 + L1 + L2 + L5 happy-path + L4 critical. L6 E2E gates deploy, not merge. |
+| Q2 | CI infrastructure | **Gitea Actions, gate tier only.** | Slice 7 adds `.gitea/workflows/test.yml` running the gate tier; full suite stays on merge-to-main. |
+| Q3 | Test DB topology | **YouPC for devs + ephemeral docker for CI.** | Local dev unchanged. Slice 7 wires Postgres service container in Gitea Actions. |
+| Q4 | Coverage target | **Critical-path only, no % gate.** | §4's 10 flows + every state-mutating service method gets a test. Coverage % output is informational in Slice 8, never a merge gate. |
+| Q5 | Production-grade floor | **Slices 1 + 4 + 5 before new feature work.** | These three land before any new paliad feature gets a coder shift. Slices 2, 3, 6 widen the floor on their own cadence. Slices 7-8 are nice-to-haves. |
+| Q6 | Slice ownership | **Head decides + rotate per profile.** | Backend slices (1, 2, 5) → backend-heavy coder. Frontend slices (3, 6) → frontend-heavy coder. E2E (4) → cross-stack. Head picks at dispatch time. |
+
+**Implementer brief (post-m-decisions):**
+
+1. **Slice 1 starts first** — migration dry-run harness + `make verify-migrations` + boot-smoke variant of `cmd/server/main_paliadin_backend_test.go`. Backend-heavy coder.
+2. **Slice 4 + Slice 5 in parallel** once Slice 1 is merged — Playwright golden-path (cross-stack coder, 5 specs) and handler integration (backend coder, auth/projects/deadlines/appointments/paliadin).
+3. Slice 7 (Gitea Actions wiring) follows once Slice 1 gate tier is proven locally.
+4. Slices 2, 3, 6 enter rotation alongside feature work — not blocking.
+5. Slice 8 (coverage reporting) lowest priority.
+
+**Status:** DESIGN APPROVED — awaiting head's dispatch of Slice 1 coder shift.

+# Design — Submission generator (t-paliad-215)
+
+**Author:** copernicus (inventor)
+**Date:** 2026-05-19
+**Issue:** m/paliad (task t-paliad-215, no Gitea issue filed yet)
+**Branch:** `mai/copernicus/inventor-submission`
+**Status:** DESIGN READY FOR REVIEW
+
+---
+
+## §0 TL;DR
+
+Each row in `paliad.deadline_rules` represents a SUBMISSION — a filing,
+hearing, or decision inside a proceeding (`submission_code` shape
+`de.inf.lg.erwidg`, `upc.inf.cfi.soc`, …). The submission generator
+takes a project + a submission_code, pulls a `.docx` template from
+Gitea, merges in project variables (party names, court, case number,
+patent number, our_side, deadline date, legal_source citation, firm
+header), and streams the result to the browser as a download.
+
+- **Scope (locked by m):** template-render to `.docx`. No LLM in v1.
+- **Template registry (locked):** Gitea — same proxy pattern as the
+  existing HL Patents Style `.dotm` in `internal/handlers/files.go`.
+- **Output (locked):** direct download, NO server-side binary
+  persistence. One audit row per generation; the bytes themselves are
+  regenerable from inputs on demand.
+- **Lookup (locked):** fallback chain — firm-specific override →
+  base for the exact `submission_code` → generic for the proceeding
+  family → ultra-generic skeleton.
+- **Slice 1 (locked):** one template, end-to-end, on one project.
+  Pick `de.inf.lg.erwidg` (Klageerwiderung) as the proof template.
+- **AI-drafted body:** explicitly OUT of scope for this task. Lives
+  in §11 as a follow-up sketch only.
+
+This design is read-only. No code, no migrations, no schema
+additions. Implementation gate is m's go/no-go on this doc.
+
+---
+
+## §1 Premises verified live (2026-05-19)
+
+Anchored against the running paliad codebase + youpc Supabase, not
+against CLAUDE.md or memory. Where a claim load-bears the design, it
+was checked against the live system.
+
+| Claim | Verification |
+|---|---|
+| Migration tracker at **102** (next is 103) | `ls internal/db/migrations/` — `102_system_audit_log` is the latest applied. |
+| `paliad.documents` table exists, is empty, no code writes to it yet | `SELECT COUNT(*) FROM paliad.documents` → 0 rows. Columns: `id, title, doc_type, file_path NULLABLE, file_size, mime_type, ai_extracted jsonb, uploaded_by, created_at, updated_at, project_id NOT NULL`. `grep` shows only `export_service.go` (audit-export only) and a comment in `render_spec.go`. No `document_service.go`, no `/api/documents` handler. |
+| `paliad.deadline_rules` carries the submission corpus | 254 total rows, 158 unique `submission_code`s, 214 `published`. Per-row fields used by the generator: `name`, `name_en`, `submission_code`, `primary_party` (claimant/defendant/court/both), `event_type` (filing/hearing/decision), `legal_source` (e.g. `DE.ZPO.276.1`, `UPC.RoP.23.1`), `is_bilateral`. |
+| Slice 1 target row exists in published state | `SELECT … WHERE submission_code='de.inf.lg.erwidg'` → `{name:"Klageerwiderung", name_en:"Statement of Defence", primary_party:"defendant", legal_source:"DE.ZPO.276.1"}`. |
+| Project rows carry all variables we need to merge | `paliad.projects` has `case_number, court, patent_number, filing_date, grant_date, our_side, instance_level, proceeding_type_id, title, reference, client_number, matter_number`. |
+| Party rows carry party variables | `paliad.parties` has `name, role, representative, contact_info jsonb` and is project-scoped via `project_id`. |
+| The HL Patents Style proxy pattern is reusable | `internal/handlers/files.go`: `fileRegistry` map → Gitea raw URL + SHA-based cache + 5-min refresh check + binary download response with `Content-Disposition`. Cache is in-process (`sync.Mutex` over a `map[string]*cacheEntry`). Single web replica today (`docker-compose.yml`), so in-process cache is fine. |
+| Email templates already use `{{.VarName}}` placeholders + a "variable contract" sidebar pattern | `internal/services/email_template_variables.go` — `EmailTemplateVariable{Name, Type, Description, SampleDE, SampleEN}` rendered in `/admin/email-templates`. Submission generator can copy this contract pattern. |
+| Audit infrastructure landed in mig 102 | `paliad.system_audit_log(id, event_type, actor_id, actor_email, scope, scope_root, metadata jsonb, created_at, updated_at)` — submission_generated events slot straight in. |
+| Branding source is `internal/branding.Name` | Default `"HLC"`, overridable via `FIRM_NAME`. Inlined into client bundles by `frontend/build.ts`. Submission templates honour this via the `{{firm.name}}` placeholder. |
+| `paliad.can_see_project(project_id)` is the canonical visibility predicate | mig 055; `internal/services/visibility.go` mirrors it. Generator gates on this; no new auth surface. |
+| Paliadin runs on the aichat backend (mRiver) with persona system | `internal/services/aichat_paliadin.go` + `personas.yaml` in `m/mAi/internal/aichat/persona/`. Owner-gated to `PaliadinOwnerEmail = matthias.siebels@hoganlovells.com`. A future AI-drafted body would be a new persona, not a new Go service. |
+
+**Doc-vs-live conflicts found:** none material for this design.
+`docs/project-status.md` still lists "Phase H AI Frist-Extraktion
+deferred" — this design does NOT revive Phase H (different surface;
+this is template merge, not document understanding).
+
+---
+
+## §2 m's decisions (2026-05-19)
+
+Locked via AskUserQuestion before drafting the rest of the design.
+
+| # | Question | m's pick | Inventor recommended? |
+|---|---|---|---|
+| Q1 | Generator scope (template / AI-draft / brief / other) | **Template-render to `.docx`** | ✅ yes |
+| Q2 | Template registry (Gitea / paliad DB / hybrid) | **Gitea** | ✅ yes |
+| Q3 | Output flow (download-only / persist binary / attach to Frist) | **Direct download, no server-side binary** | ✅ yes |
+| Q4 | Mapping (fallback chain / 1:1 / 1:N user picks) | **Fallback chain** | ✅ yes |
+| Q5 | Slice 1 scope (1 template / 3–5 templates / full corpus / skeleton-only) | **One template, end-to-end on one project** (`de.inf.lg.erwidg` Klageerwiderung) | ✅ yes |
+
+Inventor-defaulted (not asked because there's a clear right answer or
+because the question is implementation-level, not architecture-level):
+
+| # | Topic | Default | Reasoning |
+|---|---|---|---|
+| D1 | Variable engine | `{{path.dot.notation}}` placeholders in the .docx body, replaced via a Go library that handles run-fragmentation | Matches the existing email-template `{{.Var}}` shape lawyers already see in `/admin/email-templates`. See §6. |
+| D2 | Authorization | Project-team visibility only (`paliad.can_see_project`) + audit row | Matches every other write surface in paliad. No profession floor (generation is read-only on source data and produces a draft, not a binding action). |
+| D3 | Naming convention | `{rule.name}-{project.case_number}-{YYYY-MM-DD}.docx`, slashes → underscores, FIRM_NAME-aware | Mirrors how lawyers name files manually. See §7. |
+| D4 | Missing-variable behaviour | Render `[KEIN WERT: {field}]` / `[NO VALUE: {field}]` marker inline | Lets the lawyer see the gap in Word, fix in paliad, regenerate. Better than 400ing. |
+| D5 | Editor surface | Gitea-only for v1 (admin edits .docx in Word, commits to mWorkRepo) | A paliad uploader UI is Phase 2 affordance if Gitea round-trip is painful. |
+| D6 | AI-drafted body | OUT of scope for this task | §11 sketches the natural follow-up shape (new aichat persona) but does not commit to it. |

+
+**No new tables.** `paliad.documents` already exists; we write audit
+rows there but leave `file_path` NULL. The fallback chain uses
+filesystem-style paths inside the existing Gitea repo; no
+`submission_templates` table needed for Slice 1.
+
+---
+
+## §4 Slice 1 — what ships first
+
+Locked by Q5: **one template, end-to-end, on one project.**
+
+### 4.1 Target submission
+
+**`de.inf.lg.erwidg`** — Klageerwiderung (DE Verletzungs-LG).
+Reasoning:
+
+- High-frequency submission in patent practice; lawyers draft these
+  often enough that the tool earns its keep on day 1.
+- `primary_party='defendant'` — exercises the our_side variable.
+- `legal_source='DE.ZPO.276.1'` — exercises citation injection.
+- Pure-DE (no UPC complexity); easier first template for HLC's
+  Munich/Düsseldorf practice to author and review.
+- Klageerhebung (`de.inf.lg.klage`) is an obvious alternative; either
+  works. m can flip the target in his decision review if Klageerhebung
+  is the better proof case.
+
+### 4.2 Surfaces in Slice 1
+
+- **Project detail page** — new "Submissions" panel listing every
+  submission_code from the project's `proceeding_type` (via existing
+  `DeadlineRuleService`) with a `[Generieren]` button per row. Button
+  is enabled iff a template resolves AND `event_type='filing'` (no
+  `[Generieren]` on hearings/decisions — those don't have submissions).
+- **Project detail API** — `GET /api/projects/{id}/submissions` returns
+  the list of (submission_code, name, has_template) so the frontend
+  can render enabled/disabled state.
+- **Generate endpoint** — `POST /api/projects/{id}/submissions/{code}/generate`
+  returns `application/vnd.openxmlformats-officedocument.wordprocessingml.document`
+  with `Content-Disposition: attachment; filename="..."`.
+
+Slice 1 does NOT add:
+
+- A `/admin/submission-templates` editor (Gitea is the editor).
+- A Frist-detail "Generate" button (project-detail only in Slice 1;
+  Frist-level surface is a Slice 2 affordance).
+- A "Submissions" tab as a dedicated page (project-detail panel only).
+- Per-firm overrides beyond `templates/HLC/...` (the fallback chain is
+  WIRED but the only override directory exercised in Slice 1 is HLC).
+- The variable-contract sidebar UI (mirrors email-template editor) —
+  the contract is documented in §6 as code constants, surfaced as a
+  Slice 2 admin affordance.
+
+### 4.3 Slice 1 LoC estimate (informational, no time estimate)
+
+| File | Approx |
+|---|---|
+| `internal/handlers/submissions.go` (NEW) | 180 |
+| `internal/services/submission_templates.go` (NEW — registry + Gitea proxy, reuses files.go cache idea) | 200 |
+| `internal/services/submission_vars.go` (NEW — variable bag builder) | 220 |
+| `internal/services/submission_render.go` (NEW — docx merge engine wrapper) | 120 |
+| `internal/services/submission_render_test.go` (placeholder coverage + missing-var marker) | 180 |
+| `frontend/src/components/SubmissionsPanel.tsx` (NEW) | 80 |
+| `frontend/src/client/submissions.ts` (NEW — fetch + download) | 60 |
+| Wiring in `cmd/server/main.go` + `internal/handlers/handlers.go` | 30 |
+| i18n keys (`submissions.*`) DE+EN | 20 |
+| **Total** | **~1090 LoC** |
+
+Plus: ONE `.docx` template authored by HLC at
+`m/mWorkRepo/templates/HLC/de.inf.lg.erwidg.docx`, lawyer-reviewed
+before Slice 1 closes.
+
+---
+
+## §5 Template registry (Gitea-backed)
+
+### 5.1 Gitea layout
+
+```
+m/mWorkRepo (existing repo)
+└── templates/
+    ├── HLC/                              # FIRM_NAME-keyed override dir
+    │   └── de.inf.lg.erwidg.docx        # Slice 1 ships THIS file
+    ├── _base/                            # Cross-firm baseline
+    │   ├── de.inf.lg.erwidg.docx        # (Phase 2+)

+    └── README.md                         # placeholder reference for authors
+```
+
+Naming convention is the submission_code with a `.docx` suffix.
+Proceeding-family fallback is the submission_code's first two
+dot-segments (`de.inf.lg` from `de.inf.lg.erwidg`).
+
+### 5.2 Lookup algorithm
+
+```go
+// services/submission_templates.go
+func (r *TemplateRegistry) Resolve(ctx context.Context, code string) (Template, error) {
+    firm := branding.Name                 // "HLC", or whatever FIRM_NAME is
+    family := familyOf(code)              // "de.inf.lg" from "de.inf.lg.erwidg"
+    candidates := []string{
+        fmt.Sprintf("templates/%s/%s.docx", firm, code),
+        fmt.Sprintf("templates/_base/%s.docx", code),
+        fmt.Sprintf("templates/_base/%s.docx", family),
+        "templates/_base/_skeleton.docx",
+    }
+    for _, path := range candidates {
+        if tmpl, ok := r.fetch(ctx, path); ok {
+            return tmpl, nil
+        }
+    }
+    return Template{}, ErrNoTemplate
+}
+```
+
+`fetch` does the same SHA-cache dance `handlers/files.go` already
+does, scoped to the templates subtree.
+
+### 5.3 Gitea auth
+
+Reuses `GITEA_TOKEN` env var that already exists for the HL Patents
+Style proxy. `m/mWorkRepo` is the same repo, same access token. No
+new secret to configure.
+
+### 5.4 What happens when no template resolves
+
+The fallback chain ends at `_skeleton.docx`. The skeleton is an
+intentionally bare-bones .docx (firm letterhead + party block + court
+address + case number + signature stub) that ships as part of the
+initial template set. In practice every Generate request resolves to
+something — but if even the skeleton 404s (misconfigured repo), the
+generator returns `503` with a clear error, the SubmissionsPanel
+button surfaces "Vorlagen-Repository nicht erreichbar".
+
+---
+
+## §6 Variable interpolation
+
+### 6.1 Engine
+
+Plain text replacement of `{{path.dot.notation}}` placeholders in the
+.docx body. Whitespace inside braces is trimmed
+(`{{ project.case_number }}` ≡ `{{project.case_number}}`).
+
+Implementation: a Go library that handles Word's run-fragmentation
+correctly (Word may split `{{project.case_number}}` across multiple
+`<w:r>` runs during editing; naive find/replace breaks). Candidates:
+
+- **`github.com/lukasjarosch/go-docx`** (~2k stars, MIT, pure Go,
+  maintained). Handles run-merging before replacement. **Inventor
+  recommendation.**
+- `github.com/nguyenthenguyen/docx` — older, less active.
+- Custom in-house implementation — ~200 LoC for a minimal robust
+  replacer that walks the document XML and merges runs that fall
+  inside a `{{…}}` span. Fallback if the library doesn't pan out.
+
+Slice 1: try `lukasjarosch/go-docx` first; if it has dealbreaker bugs
+(e.g. blows up on Word's autocorrect runs), fall back to the in-house
+~200 LoC walker. The library choice is an implementation detail; the
+placeholder syntax stays the same either way.
+
+### 6.2 Variable contract (v1 placeholder set)
+
+```
+{{firm.name}}                        — HLC (or whatever FIRM_NAME is)
+{{firm.signature_block}}             — Phase 2; v1 renders empty string
+
+{{today}}                            — 2026-05-19 (ISO)
+{{today.long_de}}                    — "19. Mai 2026"
+{{today.long_en}}                    — "19 May 2026"

+{{project.our_side_de}}              — "Klägerin" | "Beklagte"
+{{project.instance_level}}           — "lg" | "olg" | "bgh" | ...
+{{project.proceeding.code}}          — e.g. "de.inf.lg"
+{{project.proceeding.name}}          — Verletzungsklage am Landgericht
+{{project.client_number}}            — paliad.projects.client_number
+{{project.matter_number}}            — paliad.projects.matter_number
+
+{{parties.claimant.name}}            — first paliad.parties row with role='claimant'
+{{parties.claimant.representative}}  — paliad.parties.representative
+{{parties.defendant.name}}           — first row with role='defendant'
+{{parties.defendant.representative}} — paliad.parties.representative
+{{parties.other.name}}               — first row with role NOT IN ('claimant','defendant') — court, intervener, etc.
+
+{{rule.submission_code}}             — "de.inf.lg.erwidg"
+{{rule.name}}                        — "Klageerwiderung"
+{{rule.name_en}}                     — "Statement of Defence"
+{{rule.legal_source}}                — "DE.ZPO.276.1"
+{{rule.legal_source_pretty}}         — "§ 276 Abs. 1 ZPO"

+{{rule.event_type}}                  — "filing"
+
+{{deadline.due_date}}                — date of the next pending deadline for this rule on this project
+{{deadline.due_date_long_de}}        — "26. Juni 2026"
+{{deadline.computed_from}}           — anchor description (e.g. "Klageerhebung am 12.05.2026 +6 Wochen")
+```
+
+Per-firm extensions (e.g. `{{firm.signature_block}}` filled from a
+table) are Phase 2.
+
+### 6.3 Variable bag construction
+
+`services/submission_vars.go` builds a flat `map[string]string`
+keyed by the dotted-path placeholders above. One pass over:
+
+1. `branding.Name` for `{{firm.*}}`
+2. `time.Now()` (with `Europe/Berlin` locale for the long forms) for
+   `{{today.*}}`
+3. `userService.GetByID()` for `{{user.*}}`
+4. `projectService.GetByID()` for `{{project.*}}`
+5. `partyService.ListByProject()` for `{{parties.*}}`
+6. `deadlineRuleService.GetByCode()` for `{{rule.*}}`
+7. `deadlineService.NextByRuleOnProject()` for `{{deadline.*}}`
+
+Missing values render as `[KEIN WERT: {dotted.path}]` (DE) or
+`[NO VALUE: {dotted.path}]` (EN) based on user locale. This is by
+design — the lawyer sees the gap in Word, fixes it (either in Word
+or in paliad and regenerates), rather than getting a 400 with a list
+of missing fields they then have to chase.
+
+### 6.4 Pretty-printing the legal_source
+
+`legal_source` in the rule corpus is shorthand
+(`DE.ZPO.276.1`, `UPC.RoP.23.1`). Lawyers don't want that in a brief;
+they want `§ 276 Abs. 1 ZPO` or `Rule 23.1 RoP UPC`.
+
+Slice 1 ships a small pretty-printer (`legalSourcePretty`) that knows
+the families we currently use:
+
+| Prefix | Pretty form (DE) | Pretty form (EN) |
+|---|---|---|
+| `DE.ZPO.<§>.<Abs>` | `§ <§> Abs. <Abs> ZPO` | `Section <§>(<Abs>) ZPO` |
+| `DE.ZPO.<§>` | `§ <§> ZPO` | `Section <§> ZPO` |
+| `UPC.RoP.<Rule>.<Sub>` | `Regel <Rule>.<Sub> VerfO UPC` | `Rule <Rule>.<Sub> RoP UPC` |
+| `UPC.RoP.<Rule>` | `Regel <Rule> VerfO UPC` | `Rule <Rule> RoP UPC` |
+| `DE.PatG.<§>` | `§ <§> PatG` | `Section <§> PatG` |
+| `EPC.<Art>` | `Art. <Art> EPÜ` | `Art. <Art> EPC` |
+| (unknown) | original string | original string |
+
+Unrecognised prefixes pass through unchanged (better than an
+incorrect prettification). The function is pure and unit-tested.
+
+---
+
+## §7 File naming
+
+Generated file name:
+
+```
+{rule.name}-{project.case_number}-{YYYY-MM-DD}.docx
+```
+
+Concrete example for the Slice 1 happy path:
+
+```
+Klageerwiderung-2 O 123_25-2026-05-19.docx
+```
+
+Rules:
+
+- `rule.name` honours user locale (`Klageerwiderung` for DE,
+  `Statement of Defence` for EN).
+- `project.case_number` slash/backslash → underscore (Word file name
+  hygiene), other characters preserved.
+- Date is ISO at server-local (`Europe/Berlin`) date.
+- If `project.case_number` is empty → fall back to a short hash of
+  `project_id` (8 hex chars) so the file still has a stable identifier
+  the lawyer can rename without losing track.
+
+---
+
+## §8 Authorization
+
+- **Visibility gate:** `paliad.can_see_project(project_id)` — anyone
+  who can see the project can generate. Matches every other write
+  surface on the project. The endpoint inlines the predicate;
+  unauthorised callers get 404 (not 403, to avoid project
+  enumeration).
+- **No profession floor.** A paralegal can generate a draft of a
+  Klageerwiderung; the draft is a Word doc that needs the associate's
+  approval downstream (in Word, on the document itself). Adding an
+  approval gate on generation would slow the workflow without
+  preventing anything that paliad's existing approval system doesn't
+  already cover at the substantive-act layer.
+- **Owner gate (Paliadin) does NOT apply.** This is the
+  submission-template engine, not Paliadin. All paliad users get the
+  feature once a template exists for the proceeding their project is
+  in.
+
+---
+
+## §9 Audit trail
+
+Two records per generation:
+
+### 9.1 `paliad.documents` row (audit-only, no binary)
+
+```sql
+INSERT INTO paliad.documents (id, title, doc_type, file_path, file_size,
+                              mime_type, ai_extracted, uploaded_by,
+                              project_id)
+VALUES (gen_random_uuid(),
+        '{rule.name} (generiert {YYYY-MM-DD})',
+        'generated_submission',           -- new doc_type value
+        NULL,                              -- no on-disk path
+        NULL,                              -- no file size (binary not persisted)
+        'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
+        jsonb_build_object(
+            'submission_code', $1,
+            'template_path',  $2,         -- the gitea path we resolved
+            'template_sha',   $3,         -- pinned SHA from the cache fetch
+            'firm',           $4),
+        $user_id,
+        $project_id);
+```
+
+- `doc_type='generated_submission'` is a new value; no CHECK constraint
+  on doc_type today so this is additive.
+- `file_path NULL` is the marker that says "regenerate from inputs on
+  demand". The /api/projects/{id}/documents listing UI (Phase 2) will
+  surface a `[Erneut generieren]` action for these rows.
+- `ai_extracted` jsonb is repurposed for generation provenance
+  (template SHA, firm at time of generation). Naming is unfortunate
+  but the column shape fits; renaming the column is out of scope for
+  this task.
+
+### 9.2 `paliad.system_audit_log` row
+
+```sql
+INSERT INTO paliad.system_audit_log (event_type, actor_id, actor_email,
+                                     scope, scope_root, metadata)
+VALUES ('submission.generated',
+        $user_id,
+        $user_email,
+        'project',
+        $project_id::text,
+        jsonb_build_object(
+            'submission_code', $1,
+            'template_path',  $2,
+            'template_sha',   $3,
+            'document_id',    $document_id,
+            'firm',           $4));
+```
+
+Mirrors the existing `system_audit_log` event_type convention
+(`*.created`, `*.updated`, etc., from t-paliad-214).
+
+### 9.3 Verlauf entry (project event)
+
+`paliad.project_events` gets a row with `event_type='submission_generated'`
+and `timeline_kind='custom_milestone'` so the generation surfaces in
+SmartTimeline's audit-log toggle and on the project's Verlauf list.
+This is the user-visible footprint; the `system_audit_log` entry is
+the admin-visible audit footprint.
+
+---
+
+## §10 Frontend surface
+
+### 10.1 Slice 1 — SubmissionsPanel on project detail
+
+A new panel below the existing Verlauf / Deadlines panels on
+`/projects/{id}`:
+
+```
+┌─────────────────────────────────────────────────────────────────┐
+│ Schriftsätze                                                    │

+│ Klageerhebung                          [— Vorlage fehlt]        │

+└─────────────────────────────────────────────────────────────────┘
+```
+
+- Filter: only `event_type='filing'` rules from the project's
+  `proceeding_type` are listed. Hearings and decisions don't have
+  submissions.
+- Per-row state: `has_template` returned by
+  `GET /api/projects/{id}/submissions`. Disabled buttons show the
+  "Vorlage fehlt" hint (German default, English in EN locale).
+- Click `[Generieren ↓]` → POST → browser triggers download.
+- `aria-busy="true"` on the panel while a generation is in flight
+  (cheap, but lawyers feel slow networks).
+
+### 10.2 Out of scope for Slice 1
+
+- A standalone `/submissions` index page.
+- A Frist-detail "Generate" button.
+- A picker for template variants (1:N) — locked to fallback chain
+  (Q4), which is 1:1 from the user's perspective.
+- An "edit project, then regenerate" loop on the same UI.

+```
+
+Open shape questions for that follow-up (NOT for this design):
+
+- One persona per submission type, or one persona that branches on
+  `submission_code` in its system prompt?
+- Owner gate (m only) like current paliadin, or open to all
+  authenticated users?
+- Approval gate before the AI body lands in the .docx?
+- Cost accounting per generation?
+- Where does the prose context come from (notes / uploaded patent
+  spec / prior pleadings)?
+
+Re-uses, when that task fires:
+
+- This task's template engine, variable contract, fallback chain,
+  audit trail — all unchanged.
+- Just a new placeholder family (`{{ai.*}}`) + a new aichat persona +
+  a new admin gate.

+## §12 Slice plan beyond Slice 1
+
+| Slice | Scope |
+|---|---|
+| 1 | One template (`de.inf.lg.erwidg`), engine + fallback chain + audit + SubmissionsPanel on project detail. THIS DESIGN. |
+| 2 | 3–5 more templates (Klageerhebung, SoC `upc.inf.cfi.soc`, SoD `upc.inf.cfi.sod`, Berufungsbegründung `de.inf.olg.begruendung`). Template authoring effort, no new architecture. |
+| 3 | Variable-contract sidebar in a new `/admin/submission-templates` page (mirrors `/admin/email-templates` shape). Shows what placeholders exist, with samples. Does NOT add an uploader UI — Gitea remains the editor. |
+| 4 | Per-firm override directory exercised (first non-HLC firm onboarded). |
+| 5 | Frist-detail "Generate" button + paliad.documents.deadline_id FK (mig 103+) for per-Frist draft history. |
+| 6 | (Separate task) AI-drafted body via Paliadin persona — see §11. |
+| 7 | (Future) Paliad UI uploader as alternative to Gitea, if the round-trip is friction. |
+
+Slices 2–5 are roadmap markers, not commitments — m decides cadence.
+
+---
+
+## §13 Trade-offs flagged
+
+1. **No binary persistence is a deliberate retention choice.** If a
+   lawyer regenerates after the project state changes (party renamed,
+   case_number corrected), the "regenerated" doc differs from the
+   "original generated" doc. This is a feature, not a bug — the source
+   of truth is paliad's project state, and the .docx is a derivative.
+   But the lawyer needs to be aware: there is no "what did I generate
+   last Thursday" recovery without re-saving locally. The
+   `paliad.documents` audit row records WHAT was generated (template
+   SHA + project state hash, optionally), but not the bytes.
+
+2. **Gitea round-trip for template edits is friction.** Template
+   authors edit `.docx` in Word, save, drag to Gitea web UI (or push
+   from a local clone). The 5-min SHA cache means edits surface
+   within 5 minutes (or instantly via `POST /api/files/refresh` —
+   already wired for the HL Patents Style template). If lawyers
+   complain, Phase 7 adds an in-paliad uploader. Until then, Gitea is
+   the editor.
+
+3. **Variable contract changes are coordinated edits.** Adding a new
+   `{{project.*}}` placeholder needs both a code change (var bag) AND
+   template edits (templates won't auto-discover new placeholders).
+   The variable-contract sidebar (Slice 3) is the mitigation —
+   template authors see what's available without reading the Go code.
+
+4. **`lukasjarosch/go-docx` library risk.** ~2k stars, MIT, maintained
+   — but it's a third-party dep we haven't used before. Fallback is
+   the in-house ~200-LoC walker. The placeholder syntax doesn't change
+   either way; Slice 1 can swap engines without touching templates or
+   callers.
+
+5. **`paliad.documents.ai_extracted` is repurposed for generation
+   provenance.** Slightly ugly naming because the column was added for
+   Phase H (AI Frist-Extraktion), which never shipped. Renaming the
+   column to something like `metadata` is out of scope for this task
+   but should be folded into the migration that lands when Phase 5
+   adds `deadline_id`.
+
+6. **`paliad.parties.role='claimant'`** — multiple claimants on a
+   project (multi-party suit) → Slice 1 picks the first row. v1
+   shortcut. Templates needing multi-claimant blocks become Phase 2
+   work (with a `{{#each parties.claimants}}` shape on top of
+   `lukasjarosch/go-docx`'s loop support).
+
+7. **No Word-side `MERGEFIELD` support.** Lawyers who insert Word
+   merge fields (via Insert → Quick Parts → Field) instead of typing
+   `{{…}}` will get untouched MERGEFIELD codes in the rendered output.
+   Decision: standardise on `{{…}}` syntax (cheap to type, visible
+   in the template, predictable). Document this in the `templates/
+   README.md`.
+
+8. **No template versioning UI.** Gitea provides git history; that's
+   the canonical version trail. Bumping to "use template X as of
+   commit Y" for an old project is a manual git-checkout-and-pin
+   exercise. Phase 2+ if anyone asks; not today.
+
+---
+
+## §14 Open follow-ups (NOT blocking)
+
+These items are NOT m-decisions; they're follow-ups for the coder
+shift or future inventor passes:
+
+- **Template authoring effort.** Slice 1 needs HLC to author/review
+  the actual Klageerwiderung template. That's a legal-review task that
+  can run in parallel with the engine code (template uploaded last
+  before the slice ships). Coordinate with m on who reviews.
+- **English version of `legalSourcePretty`.** Pretty-printer table in
+  §6.4 needs an EN column for every prefix — populated from existing
+  glossary entries where possible.
+- **i18n key sweep.** `submissions.*` namespace; ~20 keys for Slice 1
+  (panel title, button labels, "Vorlage fehlt" hints, error messages
+  for 503/404/422).
+- **README for template authors.** A `templates/README.md` in
+  m/mWorkRepo listing the available placeholders + naming convention
+  + a screenshot of a working template. Coder ships this alongside
+  Slice 1.
+- **CLAUDE.md update.** Add a "Submission templates" section
+  documenting the Gitea proxy, placeholder syntax, and the
+  `submission.generated` audit event_type.
+- **Cleanup task for `ai_extracted` naming.** Issue + Phase 5 mig.
+
+---
+
+## §15 What this design does NOT do
+
+To set the scope boundary cleanly:
+
+- ❌ Generate PDFs.
+- ❌ Generate emails or any non-.docx format.
+- ❌ Edit `.docx` files inside paliad (no in-browser Word editor).
+- ❌ Upload .docx to NetDocuments or any external DMS.
+- ❌ Translate templates DE↔EN automatically.
+- ❌ Validate the generated draft against any legal rule.
+- ❌ Sign, certify, or notarise the output.
+- ❌ Send the draft to court / e-filing.
+- ❌ AI-draft any prose. (See §11.)
+- ❌ Provide a paliad-UI template editor. (Gitea is the editor.)
+- ❌ Persist generated .docx bytes server-side. (Audit row only.)
+- ❌ Add a new database table. (`paliad.documents` is enough for v1.)
+- ❌ Require a database migration. (Slice 1 is migration-free.)
+
+Each of these is a defensible future-scope item; none belong in
+Slice 1.
+
+---
+
+## §16 Recommended implementer
+
+Pattern-fluent Sonnet coder. The substrate is well-trodden:
+
+- Gitea proxy + cache: `internal/handlers/files.go` is the template
+  to lift.
+- Variable contract pattern: `internal/services/email_template_variables.go`
+  is the template to mirror (different surface, identical shape).
+- Visibility gate: `internal/services/visibility.go` +
+  `paliad.can_see_project()` — standard everywhere.
+- Audit insert: `paliad.system_audit_log` (mig 102) + `paliad.documents`
+  (existing table, first writer).
+- Frontend SubmissionsPanel: stock TSX + client/.ts pattern, same shape
+  as the existing CardLayout / EventsList panels.
+
+The only novel piece is the docx merge library integration — that's a
+~200 LoC isolated module the coder can prototype on a sample .docx
+before wiring into the project flow.
+
+NOT cronus per project memory directive.
+
+---
+
+## §17 Acceptance criteria for Slice 1
+
+The coder considers Slice 1 done when:
+
+1. Pushing a `.docx` to `m/mWorkRepo/templates/HLC/de.inf.lg.erwidg.docx`
+   and visiting any project with `proceeding_type=de.inf.lg` surfaces
+   a `[Generieren]` Klageerwiderung button.
+2. Clicking it downloads a `.docx` named per §7 with all §6.2
+   placeholders resolved (or `[KEIN WERT: …]` markers for genuinely
+   missing project fields).
+3. Opening the downloaded .docx in Word renders cleanly (no run
+   fragmentation artefacts, no broken styles).
+4. A row appears in `paliad.documents` with `doc_type='generated_submission'`,
+   `file_path=NULL`, and `ai_extracted` jsonb carrying the template
+   path + SHA.
+5. A row appears in `paliad.system_audit_log` with `event_type='submission.generated'`.
+6. A row appears in `paliad.project_events` with
+   `event_type='submission_generated'` and shows up in the project's
+   Verlauf / SmartTimeline.
+7. Calling the endpoint without project visibility returns 404.
+8. Calling the endpoint with no template anywhere in the fallback
+   chain returns 503 with a clear error.
+9. Unit tests cover: placeholder rendering happy path, missing-var
+   marker, fallback chain (all 4 levels), file naming, slash
+   sanitization, legalSourcePretty for every prefix in §6.4.
+10. `go build ./... && go vet ./... && go test ./... && bun run build`
+    all clean.
+11. Manual test on the live database (test admin
+    `tester@hlc.de` per memory) against a project with a real
+    `de.inf.lg` proceeding succeeds end-to-end.
+
+---
+
+## §18 Approval gate
+
+Per inventor SKILL.md and project CLAUDE.md: this design needs m's
+go/no-go before any coder is hired. After m approves:
+
+- The head decides whether to hire the same worker as `/mai-coder`
+  with this design as the brief, or a fresh coder.
+- A coder shift takes this doc as the spec, ships Slice 1, opens a
+  PR (no self-merge — maria's gate).
+- Phase 11 (AI-drafted body) is a SEPARATE task — not auto-spawned.
+
+Inventor parks here.

+# t-paliad-207 follow-up scope — close-out assessment
+
+**Author:** fermi (inventor)
+**Date:** 2026-05-20
+**Verdict:** **(A) DONE** — interactive session scope is shipped; remaining tail is filed-or-fileable as discrete issues, not a fresh fermi slice.
+
+---
+
+## 0. What shipped under t-paliad-207
+
+Six substantive deliveries on `mai/fermi/interactive-session`, all merged to main as of 2026-05-20 morning:
+
+1. **Verfahrensablauf + Fristenrechner polish** — jurisdiction prefix on the picked proceeding, trigger-event label derived from the root rule, flag rows lifted to `/tools/verfahrensablauf`, rule references rendered as `youpc.org/laws#…` links via new `BuildLegalSourceURL`, `Vorab-Einrede → Einspruch` rename (DE i18n).
+2. **DE proceeding picker — sub-group headers** (`Verletzungsverfahren` / `Nichtigkeitsverfahren`) + parallel labels (`LG (1. Instanz)` / `OLG (Berufung)` / …).
+3. **mig 099** — drop the `with_po` flag from the two RoP 19 rules (Einspruch is always-available, not flag-gated).
+4. **mig 100** — `upc.inf.cfi.ccr` visible rule (`Nichtigkeitswiderklage`) so the CCR filing event surfaces when `with_ccr` is set; later corrected to `priority='optional'` via mig 101.
+5. **mig 101** — strip rule-cite brackets from the two Einspruch names + flip the CCR priority `informational → optional`.
+6. **mig 102** — track-aware sequence reshuffle on `upc.inf.cfi` so at any tied date the order is infringement (Replik) → revocation (Erwiderung Nichtigkeitswiderklage) → amendment.
+7. **Notes toggle** — `Hinweise anzeigen` checkbox in the view-toggle bar; compact ⓘ hover hint when off (default), inline `timeline-notes` block when on. `localStorage` shared across both tool pages.
+
+Filed two follow-up issues during the session:
+
+- **m/paliad#39** — link DE + EPA + EU rule references to `youpc.org/laws` (depends on youpc.org ingesting the corpus).
+- **m/paliad#41** — DE proceedings as one combined timeline per type (LG→OLG→BGH, BPatG→BGH) — corpus + spawn + de-duplication + multi-instance UI.
+
+## 1. Why (A) DONE
+
+Every concrete thing m surfaced in the session was addressed and merged. The two larger unaddressed asks — combined-timeline behaviour for DE proceedings, and DE/EPA rule-link coverage — are already captured in #39 and #41 with concrete scope notes. Neither belongs as a fermi "next slice" because:
+
+- **#41** is a corpus + UI design pass of its own (3 new spawn rules, de-duplication of the existing `de.inf.lg.berufung ↔ de.inf.olg.berufung` pair, multi-court picker shape, instance markers in the timeline body). That's its own design ticket, not a fermi follow-up.
+- **#39** is primarily a youpc.org-side ingest task; the paliad-side change is a 5-line `switch` extension once youpc serves the URLs. Wait for the dependency, then small.
+
+Everything else I surfaced in the read-only audit is either pre-existing (not introduced by this session) or speculative (no user complaint behind it).
+
+## 2. Optional tail — would file as discrete issues, not a fermi slice
+
+Surfacing these for completeness; none are blocking, and most would be small enough to either roll into the existing tickets or land as one-off polish:
+
+| # | Candidate | Size | Already covered? |
+|---|---|---|---|
+| 1 | **`legal_source` backfill on 47 unsourced active rules** — query: 4 of `upc.inf.cfi`, 4 of `upc.pi.cfi` (100% gap), 6 of `upc.rev.cfi`, others. Pre-condition for #39's links to bite. | Medium — corpus research per rule | Partially: huygens did the broader citation backfill in t-paliad-208 / mig 097. This is the remaining tail. |
+| 2 | **`upc.pi.cfi` corpus completeness audit** — all 4 of its rules lack `legal_source`; likely also missing the analogous track-of-decision spawn rules to `upc.apl.merits`. | Small audit, medium fix | No — would be a fresh task. |
+| 3 | **Touch-device fallback for the ⓘ hover hint** — `title=` attribute degrades poorly on phones (no hover, no tap-to-show). Either a click-to-popover variant, or accept the gap. | Tiny | No, but no user complaint yet. |
+| 4 | **R.46 mutatis-mutandis distinction in `upc.rev.cfi.prelim` description** — when mig 101 stripped the `(R. 19 i.V.m. R. 46)` cite, the legal nuance dropped from the user-visible name. Could be surfaced in the description text where it doesn't crowd the timeline cell. | Tiny (one row update) | No. |
+| 5 | **Save-modal warning on SoD + CCR double-check** — with mig 100's new `upc.inf.cfi.ccr` rule, a user can save both `sod` and `ccr` from the same modal and get two `paliad.deadlines` rows on the same date. Today's pre-uncheck behaviour for optional priority mitigates accidental double-write but doesn't surface the duplication actively. | Small | No. |
+| 6 | **Deferred slices from earlier design docs that touch this surface**: t-paliad-179 Slice 2-4 (variant chips, lane view, side-by-side compare on `/tools/verfahrensablauf`); t-paliad-169 "+ Eintrag" CTA on the SmartTimeline (project-bound) path. | Each a separate slice. | Yes — parked from their original tasks; would be revisited when m prioritises. |
+
+None of these warrant a "next fermi slice" right now. They're polish + corpus tail, and best handled as individual issues that m can pick from.
+
+## 3. Recommendation
+
+Close t-paliad-207. Fire fermi. The remaining tail (items 1–6 above) is appropriate as a small "polish backlog" m can dip into when relevant, but not a coherent unit of work that needs a parked inventor.

+// Package db tests — migration dry-run gate.
+//
+// This is the test that catches mig-N crash-loops before they reach prod.
+// The new runner tracks applied state as a set in paliad.applied_migrations
+// (one row per migration; see migrate.go). A migration that compiles cleanly
+// but fails on apply (typo, missing column, wrong CHECK shape) crashes the
+// Dokploy container loop before paliad.de finishes binding :8080, and the
+// only way to learn about it today is to watch the deploy log.
+//
+// TestMigrations_DryRun closes that gap: for every *.up.sql in this
+// directory whose version is NOT present in paliad.applied_migrations on
+// the scratch DB, it opens a transaction, runs the SQL, and ROLLBACKs.
+// Any error fails the test with the file name + Postgres error. Always
+// non-destructive — the ROLLBACK runs even on success, so the scratch DB
+// stays at its starting set.
+//
+// "Pending" means: a version that's on disk but not in applied_migrations.
+// In CI against a fresh scratch DB (where applied_migrations either
+// doesn't exist or is empty), every migration is pending and gets
+// verified. On a developer laptop whose scratch DB is already at HEAD,
+// no migrations are pending and the test logs and passes — the protection
+// only kicks in the moment a new *.up.sql lands in the tree before the
+// developer runs `db.ApplyMigrations` against the same scratch DB.
+//
+// Requires TEST_DATABASE_URL (same pattern as the rest of the live-DB
+// tests). Skipped without it.

+-- t-paliad-209 / workstream B — submission-code prefix + rename.
+--
+-- m's 2026-05-18 call: the `paliad.deadline_rules.code` field is a
+-- SUBMISSION identifier (the event/filing within a proceeding), not the
+-- legal-citation rule code (which lives in `rule_code` / `legal_source`).
+-- Two cleanups land here:
+--
+--   1. DATA — prefix every existing submission code with its proceeding
+--      code so submission codes carry the full hierarchical shape
+--      (e.g. `inf.soc` on `upc.inf.cfi` → `upc.inf.cfi.soc`,
+--      `de_inf.klage` on `de.inf.lg` → `de.inf.lg.klage`).
+--      Algorithm: keep the proceeding-code prefix as-is, strip the
+--      old single-segment prefix (everything before the first dot in
+--      `dr.code`) and replace it with the proceeding's full `code`.
+--
+--   2. SCHEMA — rename `paliad.deadline_rules.code` → `submission_code`
+--      so future devs don't conflate it with `rule_code` (legal
+--      citation) or `proceeding_types.code`. Explicit name encodes the
+--      semantic taxonomy ratified in
+--      docs/design-proceeding-code-taxonomy-2026-05-18.md §0.1.
+--
+-- Materialized-view dependency: `paliad.deadline_search` (mig 051) has
+-- `dr.code AS rule_local_code` baked into its SELECT list. Postgres
+-- rejects RENAME COLUMN when a matview's column list still resolves
+-- via the old name — so the matview is dropped before the rename and
+-- recreated against `submission_code` afterwards, with every index
+-- reproduced. The mig 047 / 051 indexes are reproduced verbatim here.
+--
+-- IDs and FKs are untouched. `deadline_rules.proceeding_type_id` /
+-- `parent_id` / `spawn_proceeding_type_id` reference ids; no
+-- code-string FK exists on submission codes (the parent_id chain is on
+-- UUID `id`, not the code string), so the data UPDATE doesn't risk
+-- breaking joins.
+--
+-- Idempotent:
+--   * The data UPDATE is gated `WHERE dr.code NOT LIKE pt.code || '.%'`
+--     — rows already prefixed with their proceeding code (i.e. the
+--     migration ran before) are skipped.
+--   * The rename is wrapped in a DO block that checks column existence,
+--     so a second run is a no-op.
+--   * Snapshot table uses CREATE TABLE IF NOT EXISTS.
+--   * Matview drop/recreate is DROP IF EXISTS + CREATE.

+    'for the down migration; persists post-rename as the permanent '
+    'audit record.';
+
+-- =============================================================================
+-- 2. Drop the deadline_search materialized view. It bakes `dr.code AS
+--    rule_local_code` into its SELECT list (mig 051 §4), and Postgres
+--    refuses to rename a column that a matview's column list still
+--    resolves via the old name. The matview is recreated verbatim in §5
+--    against the renamed column.
+-- =============================================================================
+
+DROP MATERIALIZED VIEW IF EXISTS paliad.deadline_search;
+
+-- =============================================================================
+-- 3. Data UPDATE — prefix every submission code with its proceeding
+--    code. Algorithm:
+--      * proceeding_code = pt.code
+--      * suffix          = portion of dr.code after the first '.'
+--      * new code        = proceeding_code || '.' || suffix
+--
+--    regexp_replace('inf.soc', '^[^.]+\.', '')      = 'soc'
+--    regexp_replace('de_inf_bgh.revision', ...)     = 'revision'
+--
+--    The WHERE clause skips rows that already start with `pt.code || '.'`
+--    so re-running the migration is a no-op on already-prefixed rows.
+--    Archived rows (proceeding `_archived_litigation`) get the same
+--    treatment — they end up as `_archived_litigation.<suffix>`. The
+--    shape regex in §6 only inspects active+published rows, so the
+--    archived form sits outside the constraint by design.
+-- =============================================================================

+UPDATE paliad.deadline_rules dr
+   SET code = pt.code || '.' || regexp_replace(dr.code, '^[^.]+\.', '')

+   AND dr.code IS NOT NULL
+   AND position('.' in dr.code) > 0
+   AND dr.code NOT LIKE pt.code || '.%';
+
+-- =============================================================================
+-- 4. Rename the column. Guarded in a DO block so a second run (e.g. a
+--    fresh DB built up to mig 098 from an empty schema, or a manual
+--    re-apply) is a no-op rather than a hard error.

+--      pointing at a paliad.projects row when the scope is hierarchy-
+--      anchored. The same Appointment can be PUT into multiple of
+--      these bindings (e.g. master cal + per-project cal).
+--   2. paliad.appointment_caldav_targets — (appointment_id, binding_id)
+--      join carrying the per-target caldav_uid + caldav_etag. The
+--      canonical UID is still per-appointment (paliad-appointment-
+--      <uuid>@paliad.de) so the same event in N cals shares one UID.
+--   3. Backfill: one all_visible binding per existing
+--      user_caldav_config row, plus one target row per Appointment
+--      already pushed (caldav_uid IS NOT NULL). Backfill maps the
+--      target's binding_id to the appointment creator's binding —
+--      that matches today's Phase F semantics, where the creator's
+--      sync goroutine owns the etag.
+--
+-- The scalar columns paliad.appointments.caldav_uid / caldav_etag
+-- STAY in place through Slice 1 and Slice 2. Slice 1 keeps them as

+-- t-paliad-207 (m's interactive session) — two label/priority polish
+-- fixes on upc.inf.cfi / upc.rev.cfi:
+--
+-- 1. **CCR priority informational → optional.** m's correction
+--    2026-05-18 18:01: the Nichtigkeitswiderklage is a substantive
+--    defensive choice the defendant makes — not just an informational
+--    notice. priority='optional' renders it as an unchecked save row
+--    the user can opt into. The fermi amend (commit e8d658a) flipping
+--    this didn't land in main — paliadin's merge of mig 100 (commit
+--    c10f8cf, merge 4ddcd28) picked up the pre-amend 'informational'
+--    version. This is the recovery.
+--
+-- 2. **Strip rule citation from Einspruch names.** m's correction
+--    2026-05-18 18:08: every other rule name in the corpus carries
+--    the act-name without a parenthetical rule cite (Klageerwiderung,
+--    Antrag auf Patentänderung, Replik, etc.). The Einspruch rule
+--    names are the outliers:
+--      upc.inf.cfi.prelim  "Einspruch (R. 19 VerfO)"            → "Einspruch"
+--      upc.rev.cfi.prelim  "Einspruch (R. 19 i.V.m. R. 46 VerfO)" → "Einspruch"
+--    and EN equivalents:
+--      "Preliminary Objection (RoP 19)" → "Preliminary Objection"
+--      "Preliminary Objection (RoP 19 in conjunction with RoP 46)"
+--                                      → "Preliminary Objection"
+--    The legal_source / rule_code columns already carry the citation
+--    and render in the deadline card's meta line, so the name stays
+--    clean. The R.46-i.V.m. distinction is preserved in the legal
+--    source field (RoP.019.1 for both — m may want to further
+--    differentiate; flagged in description text instead).
+--
+-- audit_reason set_config required at the top — the deadline_rules
+-- audit trigger raises EXCEPTION 'audit reason required' on any
+-- mutation without it (cf. mig 099 hotfix history).
