mAi: #117 + #118 - t-paliad-285/-286 UPC dmgs+pi court followup (mig 133)

Adds the post-submission court phase to upc.dmgs.cfi and the appeal
route to upc.pi.cfi. The Verfahrensablauf timeline currently stops at
the last party submission (dmgs.rejoin / pi.order); without these rows
the interim conference / oral hearing / decision / appeal sub-tree
never renders, even though atlas's #96 spawn mechanism is in place.

Migration 133 (single slot, coordinated with knuth's #116 on 132):

Section A — UPC Damages tree end (#117):
- upc.dmgs.cfi.interim       court-set, R.105
- upc.dmgs.cfi.oral          court-set, R.118 / R.250
- upc.dmgs.cfi.decision      court-set, R.118 / R.144
- upc.dmgs.cfi.appeal_spawn  2mo, R.220.1(a) / R.224.1(a), spawn → upc.apl.merits

Section B — UPC PI appeal route (#118):
- upc.pi.cfi.appeal_spawn    2mo, R.220.1(a) / R.224.1(a), spawn → upc.apl.merits
  PI orders under R.211 dispose of the urgent question and ride the
  main 2-month track; the 15-day R.220.1(c) order track does not apply.

Same shape as mig 095 inf.appeal_spawn and the upc.inf.cfi
interim/oral/decision rows from mig 012. Court-set rows reuse the
shared interim-conference / oral-hearing / decision concepts.

+# Design — Per-event-card optional choices on the Verfahrensablauf timeline
+
+**Author:** atlas (inventor)
+**Date:** 2026-05-25
+**Task:** t-paliad-265 (m/paliad#96)
+**Branch:** `mai/atlas/inventor-per-event-card`
+**Status:** READY FOR REVIEW — m gates inventor → coder transition.
+
+---
+
+## 0. TL;DR
+
+> **m's decisions landed 2026-05-25** — see §11. Persisted table, caret+popover, per-card-overrides-page-level, and m chose to bundle Slice A + Slice B into one coder shift (over the inventor (R) of "Slice A first"). All other picks matched inventor recommendations.
+
+The Verfahrensablauf timeline today carries **two** projection knobs at the page level — `side` (who-we-are) and `appellant` (who-initiated). Both are **global** for the whole timeline. m wants three more knobs, but **per event card**, not page-level:
+
+1. **Appellant per decision card** — if a decision is appealable, the user picks which side appealed (Claimant / Defendant / Both / None). Different decisions in the same timeline can have different appellants.
+2. **Include Nichtigkeitswiderklage on Klageerwiderung** — toggling this on a single Klageerwiderung card flips on the existing `with_ccr` flag for everything downstream of that card.
+3. **Skip an optional event** — for any rule marked `priority='optional'`, a per-card "don't consider for this case" toggle hides downstream consequences.
+
+The flow these choices drive is **already there** — `condition_expr` jsonb gates (`with_ccr`, `with_amend`, `with_cci`) plus the page-level appellant selector. What's missing is (a) **per-card** scope and (b) **per-project persistence**.
+
+Recommendation: persist choices in a new `paliad.project_event_choices` table; expose them through a popover-on-caret affordance on the relevant cards only; map them into the existing `CalcOptions.Flags` + a new per-rule `Appellants` map at projection time. Two slices: **Slice A** (appellant-per-decision + skip-optional, narrow + bounded), **Slice B** (include-CCR-on-Klageerwiderung, requires per-card flag-scoping in the projection engine — bigger).
+
+---
+
+## 1. Premises verified live (before designing)
+
+CLAUDE.md / memory / issue text can drift; the live system can't. Each load-bearing premise below was probed against the live DB or live source on 2026-05-25.
+
+### Schema
+
+- **Migration tracker at 127** (`paliad.paliad_schema_migrations`). Next migration: 128. No new table for `project_event_choices` exists today.
+- **`paliad.deadline_rules` carries `condition_expr jsonb`** already. The flag-evaluation engine (`internal/services/fristenrechner.go:208 Calculate`, `evalConditionExpr` at line ~947) walks the jsonb tree and skips rules whose gate is unsatisfied. Today's gates are `{"flag":"with_ccr"}`, `{"flag":"with_amend"}`, `{"flag":"with_cci"}`, and `{"op":"and","args":[…]}` combinations.
+- **`with_ccr` is the existing Nichtigkeitswiderklage gate.** Verified live: 7 upc.inf.cfi rules gate on it (`upc.inf.cfi.reply`, `…rejoin`, `…ccr`, `…def_to_ccr`, `…reply_def_ccr`, `…rejoin_reply_ccr`, plus `upc.inf.cfi.app_to_amend` which additionally requires `with_amend`).
+- **`priority` column** has 4 values: `mandatory`, `recommended`, `optional`, `informational`. Live counts (deadline_rules table-wide): 230 mandatory / 18 recommended / 6 optional / (informational not in count, must be 0 or absent). The "skip optional" affordance keys off `priority='optional'`.
+- **`event_type` discriminator** exists with values `filing`, `decision`, `hearing`. The "appellant-per-decision" affordance keys off `event_type='decision'`. Live: every decision rule has `primary_party='court'`.
+- **`paliad.projects.our_side`** exists (column added before mig 112; values today include `claimant|defendant|applicant|appellant|respondent|third_party|other`). It is the broad project-level side axis t-paliad-257 / #88 hooked into.
+- **NO `appellant` column on `paliad.projects`** — the appellant axis lives only in the URL query (`?appellant=claimant|defendant`) in `client/verfahrensablauf.ts:73-89`.
+
+### Frontend
+
+- `frontend/src/client/views/verfahrensablauf-core.ts` is the **shared rendering core** for both `/tools/verfahrensablauf` and `/tools/fristenrechner`. Per-card UI affordances added here surface on both pages automatically.
+- `bucketDeadlinesIntoColumns(deadlines, {side, appellant})` (line 496) is the **pure routing primitive**; column placement is computed without DOM. Unit-tested in `verfahrensablauf-core.test.ts`.
+- `deadlineCardHtml(dl, {showParty, editable, showNotes})` (line 254) is the **per-card renderer**. There is no per-card props channel for "choices" yet — that's the surface this design extends.
+- `client/verfahrensablauf.ts` and `client/fristenrechner.ts` both manage `currentSide` + `currentAppellant` in-memory and round-trip them through the URL (`writeSideToURL` / `writeAppellantToURL`). The pattern is mature; this design mirrors it for the new state when state stays URL-bound, and lifts it into a server-persisted store when state stays per-project.
+- `APPELLANT_AXIS_PROCEEDINGS` set (verfahrensablauf.ts:52-62) gates the page-level appellant selector to appeal-flavoured proceedings only. The per-card appellant affordance MUST NOT depend on this set — any first-instance decision is a potential appeal trigger (e.g. LG-Urteil → Berufung, BPatG-Entscheidung → BGH-Rechtsbeschwerde).
+
+### Surfaces in scope
+
+- **`/tools/verfahrensablauf`** — abstract browse, no project context. Per-card choices here are ephemeral (URL-bound) — there's no project to persist into.
+- **`/tools/fristenrechner`** — concrete projection, optionally project-bound via `?project=<id>` (`currentStep1Context.kind === "project"`). When project-bound, per-card choices persist to `paliad.project_event_choices`. When unbound, URL only.
+- **`/projects/{id}` Verlauf tab (SmartTimeline)** — separate widget (per `docs/design-smart-timeline-2026-05-08.md`); does **NOT** use `renderColumnsBody`. Per-card choices are NOT in scope for the SmartTimeline in v1 — the Verfahrensablauf core is.
+
+### What is NOT premised
+
+- The deadline_rules → procedural_events rename (#93) is **not assumed shipped**. This design uses `deadline_rules`/`rule_code` vocabulary throughout and flags the rename touch-points in §6.
+- The per-card UI does NOT require new server-side priority/event_type semantics. Both `priority='optional'` and `event_type='decision'` exist on every row.
+
+---
+
+## 2. Vision + scope
+
+m's vision (verbatim 2026-05-25 15:12):
+
+> We still have no choice to say that a specific party appealed. We may need selections within the event cards on the timeline to change it? For example for a decision we could check Appeal by... or in Klageerwiderung we can chose to include a Nichtigkeitswiderklage. Or with any optional event we can select not to consider it (because someone decided not to file it).
+
+### What changes
+
+- A **caret affordance** (▾) appears on the right edge of cards that have at least one applicable choice-kind. Click → small popover with the choices. Cards without an applicable choice render unchanged.
+- A **`choices_offered` jsonb column** on `paliad.deadline_rules` declares which choice-kinds each rule offers. Three kinds in v1:
+  - `appellant` — applicable to rules with `event_type='decision'` (no static list; engine decides).
+  - `include_ccr` — applicable to the single Klageerwiderung rule per proceeding (today: `upc.inf.cfi.def`, `de.inf.lg.erwidg`).
+  - `skip` — applicable to any rule with `priority='optional'`.
+- A **new persistence table** `paliad.project_event_choices(project_id, rule_code, choice_kind, choice_value)` holds the user's choices. Per-project, audit-logged via `paliad.system_audit_log`.
+- A **projection-time merge** turns the persisted choices into `CalcOptions.Flags` and a new `PerCardAppellants map[ruleCode]string` field, then re-runs the existing projection engine. No new flag types; `with_ccr` is the same `with_ccr`.
+
+### What stays
+
+- `bucketDeadlinesIntoColumns` and `renderColumnsBody` are extended (new opts), not replaced.
+- `condition_expr` jsonb gating semantics are unchanged. Per-card `include_ccr` choice simply means "set `with_ccr` in the flag set for this projection" — same engine.
+- Page-level `side` / `appellant` selectors stay. The per-card appellant choice is an **override layer** on top of the page-level appellant (Q4 below).
+- URL-state plumbing (`?side=…`, `?appellant=…`) stays. The page-level URL params remain the only state for unbound `/tools/verfahrensablauf`.
+
+### Out of scope (v1)
+
+- Per-card choices on the SmartTimeline (project Verlauf tab). Deferred to a follow-up when SmartTimeline matures.
+- Versioning of choices over time ("the appellant changed mid-case", "the CCR was withdrawn"). Choices are last-write-wins.
+- Cross-project propagation of choices.
+- Implementing the choice flow (coder task per slice; this is design-only).
+- A "what-if scenarios" mode (saved named scenarios).

+
+## 3. Data model
+
+### 3.1 The new table
+
+```sql
+-- migration 128_project_event_choices.up.sql
+CREATE TABLE paliad.project_event_choices (
+  id          uuid PRIMARY KEY DEFAULT gen_random_uuid(),
+  project_id  uuid NOT NULL REFERENCES paliad.projects(id) ON DELETE CASCADE,
+  rule_code   text NOT NULL,                       -- e.g. "RoP.029.a" or "de.inf.lg.urteil"
+  choice_kind text NOT NULL,                       -- 'appellant' | 'include_ccr' | 'skip'
+  choice_value text NOT NULL,                      -- value namespace per kind (see §3.3)
+  created_by  uuid REFERENCES paliad.users(id) ON DELETE SET NULL,
+  created_at  timestamptz NOT NULL DEFAULT now(),
+  updated_by  uuid REFERENCES paliad.users(id) ON DELETE SET NULL,
+  updated_at  timestamptz NOT NULL DEFAULT now(),
+
+  -- One choice per (project, rule_code, kind). Re-pick is an UPDATE.
+  UNIQUE (project_id, rule_code, choice_kind)
+);
+
+CREATE INDEX project_event_choices_project_idx
+  ON paliad.project_event_choices (project_id);
+
+-- RLS: same `paliad.can_see_project(project_id)` predicate as paliad.deadlines.
+ALTER TABLE paliad.project_event_choices ENABLE ROW LEVEL SECURITY;
+CREATE POLICY project_event_choices_select ON paliad.project_event_choices
+  FOR SELECT USING (paliad.can_see_project(project_id));
+CREATE POLICY project_event_choices_mutate ON paliad.project_event_choices
+  FOR ALL USING (paliad.can_see_project(project_id))
+  WITH CHECK (paliad.can_see_project(project_id));
+```
+
+**Why this shape:**
+- Tall not wide — adding a 4th choice-kind in slice C means one more allowed `choice_kind` value, no DDL.
+- `rule_code` is the join key against `paliad.deadline_rules` (which already uses `rule_code` widely — `Calculate`, `AnchorOverrides`, the projection). Stable across rule renames provided the rename keeps the same `rule_code`.
+- UNIQUE per `(project, rule_code, kind)` makes the choice idempotent — re-picking the appellant overwrites, doesn't accumulate.
+- ON DELETE CASCADE follows the project — when a project is hard-deleted (rare; usually soft-status), the choices go with it.
+
+### 3.2 The opt-in column on `paliad.deadline_rules`
+
+```sql
+-- migration 128_project_event_choices.up.sql (same migration)
+ALTER TABLE paliad.deadline_rules
+  ADD COLUMN choices_offered jsonb;
+
+-- Example seeded values (in the same migration's data-fix block):
+--
+--   upc.inf.cfi.def → '{"include_ccr": [true, false]}'
+--   de.inf.lg.erwidg → '{"include_ccr": [true, false]}'
+--   upc.inf.cfi.decision → '{"appellant": ["claimant", "defendant", "both", "none"]}'
+--   de.inf.lg.urteil → '{"appellant": ["claimant", "defendant", "both", "none"]}'
+--   (every event_type='decision' rule)
+--   upc.inf.cfi.ccr (priority='optional') → '{"skip": [true, false]}'
+--   (every priority='optional' rule)
+```
+
+**Alternative considered + rejected:** infer offering at projection-time from `(event_type, priority, submission_code)` heuristics. Rejected because:
+- The Klageerwiderung rule is identified only by its `submission_code` slug. Tying the engine to a hardcoded slug list inside the projection service is brittle (mig 124 + future Wave-1 fixes rename slugs); declaring `choices_offered` in data lets the audit ship them without a code change.
+- A `skip` toggle that's automatically derived from `priority='optional'` is consistent today but may diverge tomorrow (an optional rule we DON'T want skippable, or a non-optional rule we DO want skippable). The opt-in jsonb keeps the choice axis decoupled from `priority`.
+
+### 3.3 Value namespaces per kind
+
+| `choice_kind` | `choice_value` valid set | Default when no row exists |
+|---|---|---|
+| `appellant` | `"claimant"` / `"defendant"` / `"both"` / `"none"` | inherits page-level appellant (URL `?appellant=`), else `null` (treated as "not yet picked" — render appeal-deadlines greyed) |
+| `include_ccr` | `"true"` / `"false"` | `"false"` (no CCR until user opts in — matches current default flag set) |
+| `skip` | `"true"` / `"false"` | `"false"` (rule renders normally) |
+
+Values are stored as `text` not `boolean` so the same column scales to multi-valued kinds (appellant has 4 values; future kinds may have N). Coercion lives in the service layer.
+
+### 3.4 Audit trail
+
+Every INSERT / UPDATE / DELETE on `project_event_choices` writes a row to `paliad.system_audit_log` (the standard sink mig 102 introduced) with `event_type='project_event_choice.set'` and the changed `(rule_code, kind, value)` in `metadata jsonb`. Pattern mirrors `paliad.deadlines.status_changed` audit rows.
+
+---
+
+## 4. Projection flow
+
+The existing projection engine is a single Go function: `FristenrechnerService.Calculate(ctx, proceedingCode, triggerDateStr, opts CalcOptions)`. Two changes:
+
+### 4.1 Extending `CalcOptions`
+
+```go
+type CalcOptions struct {
+    // ...existing fields...
+    Flags           []string             // <-- already exists
+    AnchorOverrides map[string]string    // <-- already exists
+
+    // NEW — per-card overrides surfaced by the per-event-card choices.
+    // Keyed by deadline_rules.rule_code.
+    //
+    //   PerCardAppellant: when a decision rule's rule_code is in this map,
+    //     the appellant for downstream rules whose parent is THAT decision
+    //     is set to the value here. Overrides any global Appellant.
+    //
+    //   SkipRules: when a rule's rule_code is in this set, the rule is
+    //     suppressed AND its descendants are suppressed. Same suppression
+    //     path as a failed condition_expr gate.
+    //
+    //   IncludeCCRFor: when a rule's rule_code is in this set, the with_ccr
+    //     flag is treated as set in the flag context FROM that rule
+    //     onward (i.e. for that rule's descendants). On v1 with a single
+    //     Klageerwiderung-per-proceeding, this is equivalent to a project-
+    //     wide with_ccr — but the per-card scope leaves room for future
+    //     proceedings with multiple CCR entry points.
+    PerCardAppellant map[string]string   // rule_code → "claimant"|"defendant"|"both"|"none"
+    SkipRules        map[string]struct{} // set of rule_code
+    IncludeCCRFor    map[string]struct{} // set of rule_code
+}
+```
+
+The handler reads `project_event_choices` for the project (if project-bound) and folds them into these fields before calling `Calculate`. When called unbound (URL-only, `/tools/verfahrensablauf` without project), the maps come from URL params instead (see §5.2).
+
+### 4.2 Three engine changes
+
+1. **SkipRules suppression**: in the post-condition_expr filter pass (`Calculate` around line 333 where the gate is evaluated), additionally drop any rule whose `rule_code ∈ opts.SkipRules`. Also drop its descendants (existing `parent_id` walk already handles cascading; just add the new predicate to the keep/drop decision).
+
+2. **IncludeCCRFor scope**: rather than threading a per-rule flag context (expensive change to engine), implement v1 as: **if any rule_code in IncludeCCRFor exists at all, append `"with_ccr"` to `opts.Flags`** before the gate-evaluation pass. This is correct for the v1 surface (Klageerwiderung is the only CCR-entry-point per proceeding) but loses the per-card scoping for multi-CCR cases. The full per-rule scope is **Slice B** (§7).
+
+3. **PerCardAppellant routing**: when `bucketDeadlinesIntoColumns` collapses `party=both` rows in the appellant's column, today it consults the global `opts.appellant`. Extend to consult `PerCardAppellant[ruleCode]` first — if present, that drives the collapse for descendants of that decision. Out-of-band: this changes the projection contract subtly. We surface this as **server-computed metadata** on the response (`CalculatedDeadline.AppellantContext`) so the frontend bucketer doesn't need to know about parent-chain walks — the server already does the walk.
+
+### 4.3 Wire shape
+
+The `CalculatedDeadline` Go struct + TS mirror grow one optional field:
+
+```go
+type CalculatedDeadline struct {
+    // ...existing fields...
+    AppellantContext string `json:"appellantContext,omitempty"`
+    // "claimant" | "defendant" | "both" | "none" | "" (default).
+    // Filled by the projection from the user's per-decision choice.
+    // Frontend bucketer prefers this over the page-level appellant.
+}
+```
+
+This keeps the bucketer logic local — no second pass needed.
+
+---
+
+## 5. UI / i18n
+
+### 5.1 Caret + popover affordance
+
+Each rendered card gets, when `choices_offered IS NOT NULL`, a `▾` caret on the right edge of the title line. Click → popover anchored to the caret. Popover renders one block per choice-kind the rule offers (typically one, occasionally two if a rule has both `appellant` and `skip` — none today; design holds for the future).
+
+DOM-wise: `frontend/src/client/views/verfahrensablauf-core.ts` `deadlineCardHtml` grows a `choicesCaret` segment, and a sibling module `client/views/event-card-choices.ts` (new) owns the popover open/close + commit handler. The popover commits via `POST /api/projects/{id}/event-choices` with body `{rule_code, kind, value}`; the response is the updated choice row.
+
+**Why a popover and not inline checkboxes:**
+- Inline would put a checkbox on every decision card + every optional card. ~6 decision cards + ~6 optional cards on a typical UPC.INF.CFI projection is ~12 always-on widgets per timeline. Visual noise + scan cost.
+- Popover defaults to hidden; the caret is a low-noise affordance. The selected choice surfaces as a small chip on the card title line ("Berufung: Beklagter") so the choice is glanceable without re-opening.
+- Mobile + touch: the caret is a 24×24 tap target; the popover is keyboard-dismissable.
+
+**Why not card-hover-reveal:** discoverability + touch failure (no hover on iOS).
+
+### 5.2 URL fallback (no project context)
+
+When `/tools/verfahrensablauf` is opened without a project (the abstract-browse case), per-card choices have no persistence layer. The popover still works, but commits update an **in-memory + URL** state instead:
+
+```
+?event_choices=RoP.029.a:appellant=defendant,upc.inf.cfi.ccr:skip=true
+```
+
+Compact CSV in one URL param. Read at page load, applied to `CalcOptions` via the same `PerCardAppellant` / `SkipRules` / `IncludeCCRFor` route. Shareable, ephemeral. Matches the existing `?side=` + `?appellant=` URL idiom.
+
+### 5.3 Chip indicators
+
+A card with a non-default choice gets a small chip next to the title:
+- Appellant chosen: `Berufung: Beklagter` / `Appeal: Defendant`
+- Include CCR: `mit Nichtigkeitswiderklage` / `with CCR`
+- Skipped: card itself fades to 50% opacity, body adds class `timeline-item--skipped`, chip reads `übersprungen` / `skipped` with an undo arrow.
+
+### 5.4 i18n keys (new)
+
+```
+choices.caret.title              "Optionen für dieses Ereignis"             "Options for this event"
+choices.appellant.title          "Berufung durch ..."                       "Appealed by ..."
+choices.appellant.claimant       "Klägerseite"                              "Claimant side"
+choices.appellant.defendant      "Beklagtenseite"                           "Defendant side"
+choices.appellant.both           "beide Parteien"                           "both parties"
+choices.appellant.none           "keine Berufung"                           "no appeal"
+choices.include_ccr.title        "Nichtigkeitswiderklage einbeziehen"       "Include nullity counterclaim"
+choices.skip.title               "Für diese Akte überspringen"              "Skip for this case"
+choices.skipped.chip             "übersprungen"                             "skipped"
+choices.reset                    "Auswahl zurücksetzen"                     "Reset choice"
+```
+
+### 5.5 What's removed
+
+The page-level appellant selector (URL `?appellant=`) stays for **non-decision proceedings** (the Appeal-CoA case where the appellant axis is the whole-timeline framing, not a per-decision choice). But for first-instance proceedings (UPC.INF, DE.INF.LG, etc.), the appellant axis migrates from page-level to per-decision card. The page-level selector hides when the proceeding has decision rules with `choices_offered.appellant` declared — which is the cleaner UX (one knob, in the right place).
+
+---
+
+## 6. Services + handlers (new surface)
+
+### 6.1 Go service
+
+```go
+// internal/services/event_choice_service.go (new)
+type EventChoiceService struct {
+    db *sqlx.DB
+}
+
+func (s *EventChoiceService) ListForProject(ctx context.Context, projectID uuid.UUID) ([]ProjectEventChoice, error)
+func (s *EventChoiceService) Upsert(ctx context.Context, c ProjectEventChoice) error
+func (s *EventChoiceService) Delete(ctx context.Context, projectID uuid.UUID, ruleCode, kind string) error
+
+// Used by ProjectionService to fold choices into CalcOptions.
+func (s *EventChoiceService) ToCalcOptions(choices []ProjectEventChoice) CalcOptionsAddendum
+```
+
+The `CalcOptionsAddendum` type wraps the three new map/set fields so the merge into the parent `CalcOptions` is one call from the projection handler.
+
+### 6.2 HTTP routes
+
+```
+GET    /api/projects/{id}/event-choices              → []ProjectEventChoice
+PUT    /api/projects/{id}/event-choices              → upsert one (body: {rule_code, kind, value})
+DELETE /api/projects/{id}/event-choices/{rule_code}/{kind} → remove
+```
+
+All gated by `gateOnboarded` + visibilityPredicate (project-team membership).
+
+### 6.3 Projection handler
+
+The existing `POST /api/tools/fristenrechner` handler accepts `flags`, `anchorOverrides`, `priorityDate`, `courtId`. Extend the request shape:

+  // server pulls perCardChoices from paliad.project_event_choices
+}
+```
+
+The handler merges either source into `CalcOptions` and runs `Calculate`.
+
+### 6.4 Touch points — files coder will edit
+
+- **DB**: new migration `128_project_event_choices.up.sql` + `.down.sql`. Add `choices_offered` column + seed data.
+- **Go**: `internal/services/event_choice_service.go` (new), `internal/services/fristenrechner.go` (extend `CalcOptions`, projection logic), `internal/handlers/event_choices.go` (new HTTP routes), `internal/handlers/fristenrechner.go` (request shape extension).
+- **Models**: `internal/models/models.go` — `ProjectEventChoice` struct, `CalculatedDeadline.AppellantContext` field.
+- **Frontend**: `frontend/src/client/views/verfahrensablauf-core.ts` (caret + chip in deadlineCardHtml), `frontend/src/client/views/event-card-choices.ts` (new popover module), `frontend/src/client/verfahrensablauf.ts` + `frontend/src/client/fristenrechner.ts` (URL-state plumbing for the unbound case; load project choices for the bound case).
+- **i18n**: `frontend/src/client/i18n.ts` + `frontend/src/i18n-keys.ts` — new keys per §5.4.
+- **Tests**: `internal/services/event_choice_service_test.go` (new), `internal/services/fristenrechner_test.go` (extend with PerCardAppellant + SkipRules cases), `frontend/src/client/views/verfahrensablauf-core.test.ts` (extend bucketing with `perCardAppellant` opt).
+
+### 6.5 Coordination with #93 procedural-events rename
+
+When #93 lands (and the rename ships), this design's `rule_code` references become `procedural_event.code` — same string namespace, cleaner name. Join points:
+- `project_event_choices.rule_code` → `project_event_choices.procedural_event_code` (or stays as a generic string column if #93 keeps `rule_code` as the join key).
+- `deadline_rules.choices_offered` → `procedural_events.choices_offered`.
+
+If #93 ships first, this design's migration applies to `procedural_events` instead. The data shape (jsonb + new join table) is unaffected. If THIS ships first, #93 absorbs the column in its rename.
+
+---
+
+## 7. Slice plan
+
+### Slice A — Appellant per decision + Skip optional event
+
+Two choice-kinds, narrow + bounded, do not change the gate-evaluation engine.
+
+- **DB**: migration 128 adds `project_event_choices` + `choices_offered`. Seed `choices_offered` on all `event_type='decision'` rules and all `priority='optional'` rules.
+- **Service**: `EventChoiceService` CRUD; `CalcOptions.PerCardAppellant` + `CalcOptions.SkipRules`; `Calculate` extension to honour SkipRules suppression + AppellantContext metadata.
+- **HTTP**: 3 new routes (GET / PUT / DELETE on project_event_choices); fristenrechner request extension.
+- **Frontend**: caret + popover on decision cards + optional cards; chip indicators; URL-state for the unbound case; load-on-mount for the bound case.
+- **Tests**: bucketing with PerCardAppellant; service CRUD; gate-suppression with SkipRules.
+
+Ship this slice first. It validates the popover affordance + the persistence layer end-to-end without touching the flag-evaluation engine.
+
+### Slice B — Include Nichtigkeitswiderklage on Klageerwiderung
+
+Wires `IncludeCCRFor` through the flag-evaluation engine. v1 simplification (§4.2 #2) makes this **almost** a no-op for the engine — but the per-card scope semantics need a separate inventor pass to nail down whether the simplification holds for de.inf.lg's CCR analogue (Widerklage auf Nichtigkeit) and for any future proceedings with multiple CCR entry points.
+
+- **DB**: add `include_ccr` to allowed `choice_kind` values + seed `choices_offered = '{"include_ccr": [true, false]}'` on the Klageerwiderung rows (`upc.inf.cfi.def`, `de.inf.lg.erwidg`).
+- **Service**: `CalcOptions.IncludeCCRFor`; the "if non-empty, append with_ccr to Flags" simplification.
+- **Frontend**: the include_ccr popover block (already designed; just enabling the row).
+- **Cross-flow audit**: confirm that the existing 7 upc.inf.cfi cross-flow rules + de.inf.lg analogues fire correctly when with_ccr is set via the per-card path vs. the existing page-level flag checkbox. Existing checkbox stays in v1; deprecation is a Slice C decision.
+
+### Bundling note (per m's Q4 decision 2026-05-25)
+
+A + B ship together. The slice headings above remain as a logical breakdown for the coder to follow when sequencing commits inside the single shift; they are not separate PRs. See §11 Q4 for rationale.
+
+### Slice C — Future choice-kinds
+
+Open-ended; not designed here. Examples surfaced by the t-paliad-067 audit:
+- "Bilateral hearing requested" toggle on hearing rules.
+- "Cost orders requested" toggle on cost-related rules.
+- "Stay applied" toggle on procedural events.
+
+Each new kind = one new allowed `choice_kind` value + one seed row + one popover block. Schema-stable.
+
+---
+
+## 8. Risk assessment
+
+- **Migration risk**: new table + new column, both additive. Down-migration drops table + column + reverts seed. No data loss path. Low risk.
+- **Projection correctness**: PerCardAppellant changes the bucket routing for "both" rows in chains downstream of a decision card. The unit-tested `bucketDeadlinesIntoColumns` carries the existing appellant semantics; extending it without breaking the existing test suite means new tests, not changes to existing ones. Coder MUST add the new tests before changing the bucketer.
+- **Flag-context vs per-rule-flag aliasing**: §4.2 #2 (Slice B) trades per-card precision for engine simplicity. Acceptable in v1 (Klageerwiderung is the only entry point per proceeding) but a known limitation. Document it in `internal/services/fristenrechner.go` doc comment so the next Wave-2 inventor doesn't think it's bug-free.
+- **Page-level vs per-card appellant interaction**: when both are set, per-card wins for descendants of the decision the per-card was set on; page-level still drives descendants of decisions without a per-card pick. Could confuse a user. Mitigation: the page-level appellant selector hides for first-instance proceedings (per §5.5). For appeal proceedings, the selector stays — but those proceedings have a single root decision so the conflict surface is small.
+- **Cross-proceeding consistency** (where #93's rename lives) — coordinate with the inventor on #93 if both ship in parallel.
+
+---
+
+## 9. Out of scope (recap)
+
+- SmartTimeline (project Verlauf tab) per-card choices.
+- Versioning / time-machine of choices.
+- Cross-project propagation.
+- Coder implementation (separate task per slice).
+- A "saved scenarios" feature.
+- Removal of the page-level `?appellant=` URL param for appeal proceedings.
+
+---
+
+## 10. Open questions for m
+
+The following 4 questions need m's pick. Inventor recommendations marked **(R)**. After m answers via AskUserQuestion, the picks land in §11 below as the historical record.
+
+### Q1 — State location
+
+Where do per-card choices live?
+
+- **(R) A. `paliad.project_event_choices` persisted (with URL override for what-if).** Per-case choices are real, not exploratory. Persist by default; what-if exploration handled later as a URL-override layer.
+- B. URL query state only. Ephemeral, shareable, no persistence.
+- C. Both from day one. Persisted default + URL-overridable for what-if scenarios.
+
+### Q2 — Affordance
+
+How do the choices surface on a card?
+
+- **(R) A. Caret (▾) + popover on click.** Off-by-default visual, on-tap reveal. Selected choice surfaces as a chip on the card title.
+- B. Inline checkbox/radio on every relevant card. Higher discoverability, more visual noise.
+- C. Card-hover reveals the choices. Discoverability + touch issues.
+
+### Q3 — Page-level appellant interaction
+
+When a per-card appellant is set on a decision, what happens to the page-level `?appellant=` selector?
+
+- **(R) A. Per-card overrides page-level for descendants of THAT decision.** Decisions without a per-card pick still use page-level. Most expressive.
+- B. Per-card inherits page-level unless explicitly set. Less surprising default but loses the per-decision expressiveness.
+
+### Q4 — Slice order
+
+Which slice ships first?
+
+- **(R) A. Slice A first (appellant per decision + skip optional).** Bounded, validates the popover + persistence layer without touching the flag-evaluation engine. Slice B (include-CCR) follows.
+- B. Slice B first. Higher-impact user feature but requires the engine change.
+- C. Bundle A + B in one coder shift. Slower to ship, lower per-coder load, but one less round trip.
+
+---
+
+## 11. m's decisions (2026-05-25)
+
+- **Q1 (State location):** Persisted table — `paliad.project_event_choices` per §3.1. Matches inventor (R).
+- **Q2 (Affordance):** Caret + popover with chip indicator on chosen cards per §5.1, §5.3. Matches inventor (R).
+- **Q3 (Appellant layer):** Per-card overrides page-level for descendants of that decision. Page-level still drives decisions without a per-card pick. Matches inventor (R). Implementation: `CalculatedDeadline.AppellantContext` (§4.3) carries the per-decision pick down the parent chain so the bucketer reads one field.
+- **Q4 (Slice order):** **Bundle Slice A + Slice B in one coder shift** (m picked over inventor (R) of "A first"). Reasoning: keeps the popover, persistence layer, AND the engine extension for `IncludeCCRFor` in one cohesive PR — coder + reviewer hold the full mental model once; one user-visible release; no half-shipped state where the caret exists on Klageerwiderung cards but the include-CCR pick doesn't yet wire through. Trade-off: larger PR. Mitigation: coder still organises commits per slice internally (separate test files, separate handler additions) so review can read them sequentially. See §7 slice plan — both slices implemented; ship as one.
+
+### Coder-shift implications of Q4 bundling
+
+- Migration 128 carries ALL three choice-kinds (`appellant`, `skip`, `include_ccr`) in the seed of `choices_offered`, plus the Klageerwiderung rows seeded with `{"include_ccr": [true, false]}`.
+- `CalcOptions` gains all three new fields (`PerCardAppellant`, `SkipRules`, `IncludeCCRFor`) in the same Go change.
+- The `IncludeCCRFor` v1 simplification (§4.2 #2 — "any non-empty set means append `with_ccr` to Flags") documents the per-card-scope limitation up front. Multi-CCR proceedings are a future expansion, not a v1 ship blocker.
+- Frontend popover renders all three blocks the rule offers in one render path; coder cannot half-ship by leaving include_ccr's popover branch as a TODO.
+- Tests cover the full matrix on the same branch.
+
+---
+
+## 12. Hard rules for the coder shift
+
+- Migration is 128, not anything else. Verify against `paliad.paliad_schema_migrations` MAX before authoring.
+- Tests added BEFORE projection-engine changes in fristenrechner.go (bucketer, gate, AppellantContext).
+- `go build ./... && go test ./internal/... && cd frontend && bun run build` clean.
+- No regression on `?side=` + `?appellant=` URL state.
+- DE primary, EN secondary for all new i18n keys.
+- Branch per slice: `mai/<coder>/event-card-choices-slice-a` etc.
+
+---
+
+## 13. Reporting
+
+When ready, the coder reports completion with the URL of the test project that exercises the feature, a screenshot of the popover, and the deadline-rules SQL UPDATE counts for the seeded `choices_offered` rows. Standard slice-completion shape.

+--
+--   2. paliad.deadline_rules.choices_offered jsonb — opt-in declaration

+--      reads this to decide whether to render the caret affordance on

+-- from rendering the court phase plus any downstream appeal sub-
+-- tree that atlas's #96 spawn-rendering mechanism is otherwise
+-- ready to surface.
+--
+-- Two sections in one migration (slot 133 — knuth on 132, paliadin
+-- coordinated):

+--   * docs/research-deadlines-completeness-2026-05-25.md
+--       — §2.1 (upc.dmgs.cfi has only 4 rules: R.131.2 / R.137.2 / R.139)
+--       — §D Damages table (R.144 tree-end row missing — listed
+--         in Tier 4 as "cosmetic", upgraded to Tier-0 by m's
+--         report once the wider follow-up gap was understood)
+--   * docs/audit-upc-rop-deadlines-2026-05-08.md §D row R.144,
+--     §F R.220.1(a) / R.224.1(a) (verified verbatim in youpc DB
+--     under law_type=UPCRoP).
+--   * UPC Rules of Procedure (consolidated):
+--       R.105 — Interim conference (court fixes after written
+--         procedure closes; same structural shape as the inf
+--         interim conference, already modelled as `upc.inf.cfi.interim`).
+--       R.118 — Decision after oral hearing; general rule for
+--         deciding panels.
+--       R.250 — Determination of damages decision; damages-
+--         specific decision rule (chains R.144 indication →
+--         damages award).
+--       R.144 — Final decision on damages quantum (tree-end
+--         anchor for §A3).
+--       R.220.1(a) — Appeal lies from any final decision /
+--         decision disposing of the case at first instance.
+--         A PI order under R.211 disposes of the urgent question
+--         and is therefore appealable on the main 2-month track
+--         (not the 15-day order track of R.220.1(c), which covers
+--         case-management and procedural orders requiring leave).
+--         Curie's §F table confirms the main-track wiring for
+--         decisions on merits / disposing orders.
+--       R.224.1(a) — Statement of Appeal within 2 months of
+--         service of the final decision; the deadline-notes text
+--         mirrors mig 095's inf.appeal_spawn / rev.appeal_spawn.
+--       R.224.2(a) — Statement of grounds within 4 months
+--         (separate deadline in the spawned upc.apl.merits
+--         proceeding; already present as upc.apl.merits.grounds).
+--
+-- Shape decisions (mirroring mig 012 / mig 095 conventions):
+--   * Court-set rows (interim / oral / decision) carry
+--     primary_party='court', event_type='hearing'|'decision',
+--     duration_value=0, is_court_set=true, parent_id=NULL,
+--     concept_id reuses the shared concepts already wired for
+--     upc.inf.cfi (interim-conference / oral-hearing / decision).
+--   * Spawn rows carry primary_party='both', is_spawn=true,
+--     spawn_proceeding_type_id=11 (upc.apl.merits), spawn_label
+--     identical to the merits spawn already in production. The
+--     spawn row's parent_id is the spawning decision/order row
+--     (so the audit log carries the trigger link).
+--   * No condition_expr — m's F2.3 decision recorded in mig 095
+--     §3: "the appeal deadline should always be triggered by a
+--     decision … appeal is always a possibility." Visibility
+--     filtering on the frontend hides appeals on projects where
+--     no appeal is contemplated.
+--   * sequence_order numbering follows the inf convention
+--     (40=interim, 50=oral, 60=decision, 80=appeal_spawn) so the
+--     Verfahrensablauf timeline orders consistently across
+--     proceedings. For PI the existing pi.order sits at
+--     sequence_order=3; the appeal_spawn lands at 10 (clear of
+--     the writ phase, room for future court-phase rows).
+--
+-- Idempotency: every INSERT is gated by `WHERE NOT EXISTS (… same
+-- submission_code, proceeding_type_id, lifecycle_state)`. Re-apply
+-- against an already-migrated DB inserts zero rows and the audit
+-- log carries no duplicate entries.
+--
+-- audit_reason set_config required at the top — the mig 079 trigger
