docs(t-paliad-207): close-out assessment — verdict (A) DONE

Read-only audit of the t-paliad-207 surface per paliadin's 2026-05-20
re-engage instruction. Six commits shipped under this task are now
merged. Two larger follow-ups (m/paliad#39 youpc-laws ingest + #41 DE
combined timeline) are filed with concrete scope. Remaining tail is
optional polish, best handled as discrete issues rather than a parked
inventor.

 | `PALIAD_BASE_URL` | optional | Public origin used in email links. Defaults to `https://paliad.de`; override for staging/preview. |
 | `SMTP_HOST` / `SMTP_PORT` / `SMTP_USERNAME` / `SMTP_PASSWORD` / `SMTP_FROM` / `SMTP_FROM_NAME` / `SMTP_USE_TLS` | for email | SMTP credentials for Paliad's transactional mail (reminders, invitations). Port 465 uses implicit TLS. `MailService` silently no-ops when any required var is missing — the server still boots for knowledge-platform-only deployments. |
 | `ANTHROPIC_API_KEY` | not used in PoC | Reserved for the eventual production-v1 Paliadin (the Anthropic Messages API path, see `docs/design-paliadin-2026-05-07.md` §2). The Phase 0 PoC (t-paliad-146) does NOT use this — it shells out to a local `claude` CLI via tmux instead, which uses m's existing Claude Code subscription. Set this env var only after the PoC validates and we cut over to the API-backed path. The earlier "Phase H Frist-Extraktion" reservation is dead — that feature is deferred separately (memory `b6a11b55…`). |
-| `PALIADIN_SESSION_PREFIX` | optional (default `paliad-paliadin`) | Prefix for the per-user tmux session names the Paliadin service uses (t-paliad-155). Each Paliad user gets their own session named `<prefix>-<userid8>` (first 8 hex chars of the user's UUID); conversation history accumulates per visit, `ResetSession` kills the session entirely. The persona + response protocol now live in `~/.claude/skills/paliadin/SKILL.md` (installed via `scripts/install-paliadin-skill`) — no in-process system prompt is sent. |
+| `PALIADIN_SESSION_PREFIX` | optional (default `paliad-paliadin`) | Prefix for the per-user tmux session names the legacy Paliadin service uses (t-paliad-155). Each Paliad user gets their own session named `<prefix>-<userid8>` (first 8 hex chars of the user's UUID); conversation history accumulates per visit, `ResetSession` kills the session entirely. **Skill source-of-truth moved to `m/mAi` under `skills/aichat/paliadin/` (m's 2026-05-13 decision, t-paliad-194).** The aichat backend owns installation on mRiver via its own deploy doc (`m/mAi/docs/reference/aichat-deploy.md`). Legacy `LocalPaliadinService` (PoC) and `RemotePaliadinService` (shim) still rely on `~/.claude/skills/paliadin/SKILL.md` being present on the target host — install it manually from the aichat repo until those paths are retired. |
 | `PALIADIN_REMOTE_CWD` | shim env (default `/home/m/dev/paliad`) | Working directory `paliadin-shim` uses when spawning the long-lived `claude` pane on mRiver. Must be the paliad repo root so claude picks up `.mcp.json` (project-scoped Supabase MCP); without it, the SKILL.md SQL recipes have no DB tool. Set on mRiver only — paliad's Go side never reads this. |
-| `PALIADIN_RESPONSE_DIR` | optional (default `/tmp/paliadin`) | Directory where Claude writes its per-turn response files. The Go service polls this directory for `{turn_id}.txt` files. |
+| `PALIADIN_RESPONSE_DIR` | optional (default `/tmp/paliadin`) | Directory where Claude writes its per-turn response files. The Go service polls this directory for `{turn_id}.txt` files. (Legacy `LocalPaliadinService` path only — aichat owns its own response dir at `/tmp/aichat/paliadin/`.) |
+| `PALIADIN_BACKEND` | optional (default `legacy`) | Selects which Paliadin backend boots (t-paliad-194 / m/paliad#38 Phase B). `legacy` keeps the existing tree (`PALIADIN_REMOTE_HOST` → SSH shim, else local tmux, else disabled). `aichat` opts into the centralized `m/mAi#207` backend on mRiver — `RemotePaliadinService`/`LocalPaliadinService` are bypassed and `AichatPaliadinService` issues HTTP calls instead. Parallel paths during the migration window; flip back is one env-var change. |
+| `AICHAT_URL` | required when `PALIADIN_BACKEND=aichat` | Aichat service root (typically `http://100.99.98.203:8765` over Tailscale; see `m/mAi/docs/reference/aichat-deploy.md`). No trailing slash needed. |
+| `AICHAT_TOKEN` | required when `PALIADIN_BACKEND=aichat` | Raw bearer token registered for paliad's app_id in aichat's `tokens.yaml`. Distributed via Dokploy secret per Q11 (age-encrypted at rest). |
+| `AICHAT_PERSONA` | optional (default `paliadin`) | Persona id to target. Override only when running a non-default deploy (e.g. staging persona). |
 
 > *Note on Paliadin gating (t-paliad-146):* there is **no** `PALIADIN_ENABLED` env var. Access is gated in code via `services.PaliadinOwnerEmail` (currently `matthias.siebels@hoganlovells.com`). Every other authenticated user gets a 404 on `/paliadin` and `/admin/paliadin`. This means the routes register on every paliad deploy (including paliad.de prod), but only m can reach them — and even then, prod only works if the host has `tmux` + a `claude` CLI in PATH (which the Dokploy container does not). PoC remains a laptop-only feature; the gate is in the code, not the deploy.
 | `FIRM_NAME` | optional (default `HLC`) | Display name of the firm Paliad is being branded for in this deployment. Read once at process start by `internal/branding.Name` (Go) and inlined into client bundles by `frontend/build.ts` (TypeScript). Powers every user-facing surface — landing hero, page titles, login hint, Downloads page, footer, invitation/reminder email bodies. The `ALLOWED_EMAIL_DOMAINS` whitelist is a separate concern (real DNS domains, not display name) and rotates independently. |

+# Proceeding-code taxonomy (t-paliad-204 ratified 2026-05-18)
+
+> Source of truth for `paliad.proceeding_types.code`. Every active row's
+> `code` MUST conform to the convention below. This document anchors
+> migration 096 (`internal/db/migrations/096_proceeding_code_rename.up.sql`)
+> and the post-migration determinator + fristenrechner mapping in
+> `internal/services/proceeding_mapping.go`.
+
+## 0. Why we renamed
+
+The historical `code` strings (`UPC_INF`, `DE_INF`, `EPA_OPP`, …) were
+UPPER_SNAKE jurisdiction-glued-to-acronym slugs. They were structurally
+opaque and the taxonomy grew unevenly as more proceedings entered the
+fristenrechner — `UPC_APP` covers all UPC appeals, `DE_INF_OLG` /
+`DE_INF_BGH` carry the instance hint inline, `EP_GRANT` is the only EPA
+row with no `EPA_` prefix at all. The mapping in
+`internal/services/proceeding_mapping.go` had to special-case appeal
+ambiguities (no instance hint on UPC_APP, none on the DE side either).
+After mig 095 landed the t-paliad-205 fristen gap-fill, m and paliadin
+ratified a uniform convention for the corpus, captured here.
+
+## 0.1 Convention
+
+Active proceeding codes are lowercase, dot-separated, three positions:
+
+    <jurisdiction>.<X>.<Y>
+
+* **`<jurisdiction>`** — one of `upc`, `de`, `epa`, `dpma`.
+* **`<X>` / `<Y>`** — contextual; for first-instance proceedings they are
+  `<substantive-type>.<forum>` (e.g. `de.inf.lg` for Verletzungsklage am
+  Landgericht). For appeals they are `<appeal-type>.<scope>` (e.g.
+  `upc.apl.merits`, `upc.apl.cost`, `upc.apl.order`).
+* The CHECK constraint installed by mig 096 enforces
+  `code ~ '^[a-z]+\.[a-z]+\.[a-z]+$'` on every active row, with a
+  carve-out for the legacy `_archived_litigation` bucket
+  (`code ~ '^_archived_'`).
+
+The convention is forward-looking: any new fristenrechner row added
+after mig 096 MUST conform — no further UPPER_SNAKE codes.

+continue to work unchanged.
+
+## 0.3 Sub-decisions (m's calls, 2026-05-18)
+
+### S1 — `upc.ccr.cfi` visibility
+
+`is_active=true`, visible in the determinator + dropdowns. **No rules
+attached.** When the determinator surfaces it, the UI shows the hint:
+
+> "Regeln liegen auf upc.inf.cfi (with_ccr=true); wir leiten Sie dorthin
+> weiter."
+
+Routing logic lands in `internal/services/proceeding_mapping.go` — when
+the cascade resolves to `upc.ccr.cfi`, the mapping returns the
+`upc.inf.cfi` id (=8) with `with_ccr=true` as a default flag. The peer
+exists for taxonomic completeness so users searching for
+"Widerklage" find an entry; it is not a separate rule namespace.
+
+### S2 — Abbreviations
+
+`dmgs` for damages, `disc` for discovery. m's call: short form keeps the
+codes terse and the dot-separated shape readable.
+
+### S3 — Damages appeal
+
+**NO separate code.** `upc.apl.merits` covers damages appeals — the
+spawn rules from `upc.dmgs.cfi` (none seeded today) would carry their
+own `spawn_label`. Avoids a code like `upc.apl.dmgs` whose rules would
+be empty for the foreseeable future.
+
+### S4 — NZB at BGH
+
+Single bucket `de.inf.bgh`. Rules diverging in the NZB-detour-path
+(Nichtzulassungsbeschwerde when the OLG didn't grant Revision) use a
+`with_nzb` flag instead of a separate proceeding type. Keeps the dropdown
+list shorter and matches how m practitioners think about the BGH
+instance — same destination, two ways to arrive.
+
+### S5 — DPMA appeals
+
+Generic `dpma.appeal.bpatg` / `dpma.appeal.bgh` — source-of-decision
+differentiation (was it a DPMA decision being appealed? a BPatG
+decision being further appealed to BGH?) lives at the rule level, not
+the proceeding-type level. Keeps the code namespace flat.
+
+## 0.4 Spawn-FK invariant
+
+After mig 096, the spawn FK invariant from mig 095 still holds:
+
+    deadline_rules.spawn_proceeding_type_id = 11
+       ↔ paliad.proceeding_types[id=11].code = 'upc.apl.merits'
+
+Spawn rules from `upc.inf.cfi` / `upc.rev.cfi` chain to the appeal-merits
+proceeding without code-string awareness. Same for any future spawn FK.
+
+## 0.5 Not in scope
+
+* `paliad.event_categories.slug` segments (`upc-inf`, `de-bgh-null`, …)
+  are NOT renamed. They are stable identifiers in a separate taxonomy and
+  their kebab form is presentation-layer (it appears in URL fragments).
+  Mig 096 only updates the `proceeding_type_code` text column on
+  `paliad.event_category_concepts` rows so the soft join through
+  `event_category_concepts → proceeding_types.code` keeps resolving.
+* Fee-table keys (`EPA_OPPOSITION`, `UPC_APPEAL`, …) in
+  `internal/calc/fees.go` are NOT proceeding codes — they are fee-table
+  bucket keys with their own naming. Untouched.
+* Forum bucket slugs (`upc_cfi`, `de_lg`, …) in
+  `ForumToProceedingCodes` are presentation buckets, not codes. The
+  values inside (`UPC_INF`, …) are the codes being renamed.
+
+## 0.6 References

+* `internal/db/migrations/096_proceeding_code_rename.up.sql` — the

+# Fristenrechner Gap-Fill Proposals — t-paliad-203
+
+**Date:** 2026-05-18
+**Author:** curie (researcher)
+**Status:** DRAFT — for m's review, not yet ingested via `/admin/rules`
+**Branch:** `mai/curie/fristenrechner-gap`
+**Supersedes:** t-paliad-201 (cancelled)
+**Source audit:** the four gaps surfaced by mig 093 commit message (t-paliad-200, `internal/db/migrations/093_retire_litigation_category.up.sql:40-54`) when 40 Pipeline-A litigation rules were archived under `_archived_litigation` and 7 litigation proceeding_types were dropped
+
+---
+
+## 0. Read-this-first — what was archived, what's left
+
+mig 093 (commit `40e49e8`) retired the entire `category='litigation'` rule corpus by:
+
+1. Snapshotting the 40 rules into `paliad.deadline_rules_pre_093` and the 7 proceeding_types into `paliad.proceeding_types_pre_093`.
+2. Re-homing all 40 rules under a holding proceeding_type `_archived_litigation` (id 32, `category='archived'`, `is_active=false`, `lifecycle_state='archived'`).
+3. Dropping `INF`, `REV`, `CCR`, `APM`, `APP`, `AMD`, `ZPO_CIVIL` from `paliad.proceeding_types`.
+
+The commit's own body listed four open coverage questions for legal review (lines 40-54 of `093_retire_litigation_category.up.sql`):
+
+| # | Pipeline-A rule(s) | Claim in commit body | This doc's verdict |
+|---|---|---|---|
+| 1 | `inf.prelim` (R.19, 1 month) | "not present on UPC_INF — possible coverage gap" | **Real gap.** Drafts 1.1 + 1.2 below. |
+| 2 | `inf.appeal` / `rev.appeal` / `ccr.appeal` (RoP.220.1, 2 months) into UPC_APP | "fristenrechner UPC_APP starts standalone with no spawn" | **Real gap.** Drafts 2.1 + 2.2 below. Pipeline-A's three rules collapse to two in the unified UPC_INF (CCR-as-flag) world — see § 2 FLAG. |
+| 3 | `ccr.amend` / `rev.amend` (spawn into AMD) | "superseded by `inf.app_to_amend` / `rev.app_to_amend` — safe to drop" | **Claim confirmed for patent amendment.** No new rules. § 3 documents the verification and surfaces R.263 (case-amendment) as a separate not-modelled item. |
+| 4 | `zpo.klage` / `zpo.vertanz` / `zpo.klageerw` / `zpo.berufung` | "no UPC analogue; redundant with DE_INF / DE_INF_OLG / DE_INF_BGH / DE_NULL / DE_NULL_BGH" | **Claim confirmed for klage / vertanz / berufung.** `klageerw` exists on DE_INF but with a duration discrepancy worth m's attention. § 4 details. |
+
+**Net: 4 substantive rule drafts** (1 PO on UPC_INF + 1 PO on UPC_REV + 2 merits-appeal spawns) — well under the "~4-10" estimate in the brief, and at the low end because two of the four gaps don't need new rules.
+
+### 0.1 Naming convention notes
+
+- **Appeal proceeding code referenced by ROLE, not by current code.** Per task brief and pairing with t-paliad-204 (proceeding-code abbreviation rework, m's review pending), the current `UPC_APP` (id=11) is referred to in proposals 2.1/2.2 as **"UPC infringement-appeal proceeding (RoP 220.1(a) main-judgment appeal)"** rather than by code. m picks the final `spawn_proceeding_type_id` when ingesting via `/admin/rules`.
+- **Existing rule-code pattern.** Live `UPC_INF` rules use bare prefix `inf.*` (not `upc.inf.*`), e.g. `inf.sod`, `inf.def_to_ccr`. Live `UPC_REV` rules use `rev.*`. I follow that pattern: proposed PO rules are `inf.prelim` (matching Pipeline-A's archived name) and `rev.prelim`; proposed spawn rules are `inf.appeal_spawn` / `rev.appeal_spawn` (the `_spawn` suffix disambiguates them from the existing UPC_APP-root `app.notice`, which is the *target*, not the *source*).
+- **Anchor semantics** (per `docs/audit-fristen-logic-2026-05-13.md` § 4 and `docs/proposals/orphan-concepts-2026-05-15.md` § 0.2): `parent_id NOT NULL` chains the new rule off an existing rule in the same proceeding. `trigger_event_id NOT NULL` roots the rule on a paliad/youpc trigger event. The unified Phase 2 schema (Slice 4, mig 081+082) supports both — proposals use `parent_id` whenever the natural anchor is an existing intra-proceeding rule (e.g. `inf.soc` for inf.prelim), which matches the pattern set by `inf.sod`, `inf.def_to_ccr`, etc.
+- **`condition_expr` form.** Existing UPC_INF / UPC_REV conditional rules use `{"flag":"with_ccr"}` or `{"op":"and","args":[{"flag":"with_ccr"},{"flag":"with_amend"}]}`. The proposals add three new flag names — `with_po`, `with_appeal`, and reuse `with_amend` only where existing. Flag names are surfaced as **FLAG** items for m to confirm before ingest.
+
+### 0.2 What's deliberately out of scope
+
+- **Order-appeals (R.220.2/R.220.3) spawn wiring** — the brief specifies RoP 220.1(a) (main-judgment, 2-month appeal → `UPC_APP`). The 15-day order/discretion track lives in `UPC_APP_ORDERS` and has its own root rules (`app_ord.with_leave`, `app_ord.discretion`). Spawn rules from UPC_INF/UPC_REV/UPC_PI for that track would be a separate proposal — flagged as future-work in § 6.
+- **Cost-decision-appeal spawn (R.221.1)** — `UPC_COST_APPEAL` exists with `cost.leave_app` as a root rule. Same shape as the order-appeals: future-work, not this proposal.
+- **R.263 application to amend the case** — surfaced in § 3 but not drafted as a rule because it's court-discretion (no calendar deadline computable from a fixed anchor).
+- **Vertagungsantrag (ZPO §227)** — the brief's description of Gap 4 named "Vertagungsantrag" but the Pipeline-A rule code `zpo.vertanz` is actually *Verteidigungsanzeige* (contraction of "Verteidigungs-Anzeige"), not Vertagungsantrag. There is no Vertagungsantrag rule anywhere in the corpus today; if m wants one, that's a fresh proposal. Documented in § 4 FLAG.
+
+---
+
+## 0.3 m's decisions on the open FLAGs (2026-05-18)
+
+Captured live with paliadin/head. Anything not explicitly answered defaults to curie's recommendation.
+
+### Gap 1 — Preliminary Objection
+
+- **F1.4 (CCR-defendant PO):** **NO** — do not seed a third PO rule for the patentee on a CCR. Final shape stays at 2 PO rules: `inf.prelim` + `rev.prelim`.
+- F1.1 (flag name): default to curie's `with_po`.
+- F1.2 (priority): default to curie's `optional`.
+- F1.3 (citation pattern): default to curie's `UPC.RoP.19.1` substantive-cite for both rules (cross-ref to R.46 lives in the description, not the legal_source field).
+
+### Gap 2 — Appeal spawns
+
+- **F2.1 (drop `ccr.appeal`):** **CONFIRMED** — one decision under R.118 = one 2-month appeal window. Rule 2.3 explicitly NOT seeded. Final shape stays at 2 spawn rules.
+- **F2.3 (appeal flag-gated or always-fire):** **ALWAYS-FIRE.** Rationale (m): "the appeal deadline should always be triggered by a decision … the flags for ccr / amend are different because that is something which only comes up during the proceedings and depends on a party. Appeal is always a possibility." So both `inf.appeal_spawn` and `rev.appeal_spawn` ship **without `condition_expr`** — the 2-month window unconditionally appears once `inf.decision` / `rev.decision` is anchored. Visibility filtering ("hide appeal deadlines on projects where the user doesn't care") is a frontend concern, not a rule-level flag — surfaced as follow-up (see § 6.X below).
+- F2.2 (anchor): default to curie's `parent_id = inf.decision` / `rev.decision` (consistent with how `inf.cost_app` already chains).
+
+### Gap 3 — `ccr.amend` / `rev.amend`
+
+- **F3.1 (model R.263?):** **NO** — court-discretion, no calendar deadline computable. If R.263 ever needs surfacing, it goes on the project page as a checklist item, not the fristenrechner.
+
+### Gap 4 — `zpo.*` family
+
+- **§4.3 — `de_inf.erwidg` discrepancy (6 weeks vs. court-set 2-week minimum):** **FLIP to court-set.** Klageerwiderung is statutorily court-set with a 2-week minimum under ZPO §276(1) S.2; the existing 6-week fixed-duration rule is wrong. Action at ingest: `is_court_set=true`, keep `duration_value=6, duration_unit='weeks'` as the **default display value** when no court order is yet attached, with the description noting "Gericht setzt eine Frist von mindestens zwei Wochen ab Verteidigungsanzeige (§276 Abs. 1 S. 2 ZPO)." This matches the pattern existing court-set rules use elsewhere.
+- F4.1 (legal_source backfills on `de_inf.klage` etc.): default to curie's "yes — apply the polish patches in § 4.1, § 4.2, § 4.4".
+
+### Final delta to ingest via `/admin/rules`
+
+```
+NEW RULES (4):
+  inf.prelim         UPC_INF  parent=inf.soc      1mo  RoP.19.1   flag=with_po       optional
+  rev.prelim         UPC_REV  parent=rev.app      1mo  RoP.19.1   flag=with_po       optional
+  inf.appeal_spawn   UPC_INF  parent=inf.decision 2mo  RoP.220.1.a (no flag)         optional  spawn→merits-appeal
+  rev.appeal_spawn   UPC_REV  parent=rev.decision 2mo  RoP.220.1.a (no flag)         optional  spawn→merits-appeal
+
+PATCHES on existing rules:
+  de_inf.klage       set legal_source = 'DE.ZPO.253'
+  de_inf.anzeige     (no change — already correct)
+  de_inf.erwidg      flip is_court_set = true; description note about §276 Abs.1 S.2
+  de_inf.berufung    (verify legal_source — curie's §4.4 polish patch)
+```
+
+### Follow-up surfaced — not for this proposal
+
+- **Frontend visibility toggle for appeal deadlines** — m flagged that appeals "always fire" at the rule level but the UI could hide them on projects where the user doesn't want to see them. NOT a rule-corpus question; file as a separate frontend task if/when m signals.
+- **`ccr.appeal` in `_archived_litigation`** — the Pipeline-A `ccr.appeal` row stays archived (m's call F2.1). No further action.
+- **Vertagungsantrag (ZPO §227)** — never modelled; not in scope. Open follow-up if m wants it.
+
+---
+
+## 1. Gap 1 — Preliminary Objection (RoP 19)
+
+**Status:** Real gap. Pipeline-A had `inf.prelim` (defendant, 1 month, R.19, "Rarely triggers separate decision; usually decided with main case") — archived without a fristenrechner replacement.
+
+Verification — current UPC_INF / UPC_REV corpus has zero rules with `rule_code` matching `R.19`, `RoP.019`, or any "Preliminary Objection" variant; verified via `SELECT * FROM paliad.deadline_rules WHERE rule_code ILIKE '%19%' OR name ILIKE '%vorab%' OR name ILIKE '%prelim%' AND lifecycle_state <> 'archived'` returns empty.
+
+Legal context — RoP 19 itself (Application of the Rules of Procedure, Part 1, Chapter 1, Section 4):
+
+- **R.19.1**: The defendant may, within 1 month of service of the Statement of claim, lodge a Preliminary objection concerning (a) jurisdiction and competence of the Court including any objection to the decision of the Registry to assign a case to a particular division, (b) the language of the Statement of claim (R.14), or (c) the competence of the panel to which the action has been assigned.
+- **R.19.7 / R.19.8**: The Court decides on a preliminary objection by way of order, typically before the interim conference, but may join it to the main proceedings.
+- **R.46**: The Rules in Part 1, Chapter 1 (including R.19) apply *mutatis mutandis* to revocation actions — i.e. the defendant in a revocation action (the patent proprietor) may also lodge a preliminary objection within 1 month of service of the Statement for revocation.
+
+The Pipeline-A note "Rarely triggers separate decision; usually decided with main case" is accurate practice — but the **1-month deadline to raise the objection** is hard and statutory. That deadline is what the fristenrechner needs to model.
+
+### Rule 1.1 — Preliminary Objection on UPC_INF
+
+- **Rule code:** `inf.prelim`
+- **Proceeding type:** UPC_INF (id=8)
+- **Name (DE):** Vorab-Einrede (R. 19 VerfO)
+- **Name (EN):** Preliminary Objection (RoP 19)
+- **Party:** defendant
+- **Anchor:** `parent_id = inf.soc` (the existing root rule "Klageerhebung") — same anchor pattern as `inf.sod` (Klageerwiderung, also parent=inf.soc). `inf.soc` is the trigger-date anchor; computing 1 month after `inf.soc` reads as "1 month from service of the Statement of Claim", consistent with R.19.1's wording.
+- **Duration:** 1, months
+- **Timing:** after
+- **Priority:** optional *(party decides whether to raise the objection; the 1-month period is statutory once invoked)*
+- **is_court_set:** false *(statutory period from service; not court-set)*
+- **condition_expr:** `{"flag":"with_po"}` *(only renders when the defendant indicates a PO will be filed — same shape as existing `with_ccr` / `with_amend` flags)*
+- **Legal source:** `UPC.RoP.19.1`
+- **`rule_code`:** `RoP.019.1`
+- **event_type:** `filing`
+- **Notes:** R.19.1 covers three independent grounds (a) jurisdiction/competence, (b) language under R.14, (c) panel competence. All share the same 1-month deadline. The UI rendering decision (one row vs. three rows by ground) is downstream UX, not a rule-corpus question.
+- **FLAG (F1.1):** Flag name — `with_po` is suggested by analogy to `with_ccr` / `with_amend` / `with_cci`. Alternative names: `with_preliminary_objection`, `prelim`. m's call.
+- **FLAG (F1.2):** Priority — proposed `optional` (defendant chooses); m may prefer `recommended` to surface it as a sanity-check chip on every defendant timeline. The Pipeline-A predecessor had `is_optional=true / is_mandatory=false` per the old binary schema, which maps cleanly to `priority='optional'` in the post-Slice-3 enum.
+
+### Rule 1.2 — Preliminary Objection on UPC_REV
+
+- **Rule code:** `rev.prelim`
+- **Proceeding type:** UPC_REV (id=9)
+- **Name (DE):** Vorab-Einrede (R. 19 i.V.m. R. 46 VerfO)
+- **Name (EN):** Preliminary Objection (RoP 19 in conjunction with RoP 46)
+- **Party:** defendant *(in a revocation action the patentee is the defendant)*
+- **Anchor:** `parent_id = rev.app` (the existing root rule "Nichtigkeitsklage" — analogous to `rev.defence` which also parents off `rev.app`)
+- **Duration:** 1, months
+- **Timing:** after
+- **Priority:** optional
+- **is_court_set:** false
+- **condition_expr:** `{"flag":"with_po"}` *(same flag as 1.1 — a PO is a PO; the user sets `with_po=true` on a UPC_REV project when the patentee plans to lodge one)*
+- **Legal source:** `UPC.RoP.46` *(R.46 makes R.19 applicable to revocation actions; cite R.46 as the operative provision because RoP 19's literal text only addresses infringement)*
+- **`rule_code`:** `RoP.046` *(or `RoP.019.1` with a note — m's call; see FLAG F1.3)*
+- **event_type:** `filing`
+- **Notes:** Functionally identical to Rule 1.1 but rooted on UPC_REV. The grounds are narrower in practice (language and panel competence are the main triggers — jurisdiction is rarely contested in pure revocation actions because the UPC's jurisdiction over revocation of unitary patents is exclusive). But the 1-month statutory window is identical.
+- **FLAG (F1.3):** Legal-source citation — should this read `UPC.RoP.46` (operative provision for revocation) or `UPC.RoP.19.1` (substantive content)? Existing rules use the substantive citation (e.g. `inf.def_to_ccr` cites `UPC.RoP.29.a`, not the cross-reference that brings R.29 into the UPC_INF flow). I lean `UPC.RoP.19.1` with `rule_code='RoP.019.1'` to match that pattern; the cross-reference to R.46 belongs in the description, not the citation field.
+- **FLAG (F1.4):** Does paliad want **counterclaim-defendant** PO rules too? Specifically, when UPC_INF has `with_ccr=true`, the *claimant* (patentee) becomes the de-facto-defendant for the CCR portion. Does the claimant get a 1-month PO window from service of the CCR? My read of R.19 + R.46 + R.25: yes — the CCR triggers a fresh R.19 window for the claimant, anchored on service of the SoD-with-CCR. But this would be a third rule (`inf.prelim_ccr`, party=claimant, parent=inf.sod, 1 month, condition_expr={"op":"and","args":[{"flag":"with_ccr"},{"flag":"with_po_ccr"}]}). I'm **not** drafting it pending m's confirmation; either it's truly there in the case law or it's an over-reading on my part. Lex-research won't help here because there's no relevant published UPC PO case on a CCR yet (R.46 + R.25 cross-reads are theoretical).
+
+**Summary for Gap 1:** 2 new rules drafted (one on UPC_INF, one on UPC_REV). 4 FLAGs. Potential third rule (CCR-PO) deferred pending m's read.
+
+---
+
+## 2. Gap 2 — Cross-proceeding APP spawns (RoP 220.1(a))
+
+**Status:** Real gap. Pipeline-A had three placeholder rules (`inf.appeal`, `rev.appeal`, `ccr.appeal`, all 2 months, RoP.220.1, is_spawn=true) — but their `spawn_proceeding_type_id` was NULL so they weren't functional spawns either. Fristenrechner UPC_APP currently starts standalone with `app.notice` as its root rule (party=both, 2 months, RoP.220.1).
+
+Verification — current corpus has zero `is_spawn=true AND is_active=true AND lifecycle_state<>'archived'` rules; the `spawn_proceeding_type_id` column on `paliad.deadline_rules` is unused in the live data (Slice 7 wiring was the design intent but no real spawns have been seeded yet).
+
+Legal context — RoP 220 (Decisions and orders which may be appealed):
+
+- **R.220.1(a)**: Final decisions under R.118 may be appealed. The appeal period is **2 months of service** of the decision (R.224.1(a)).
+- **R.224.1(a)**: The Statement of appeal must be lodged within 2 months of service of the decision.
+- **R.224.2(a)**: The Statement of grounds of appeal must be lodged within 4 months of service of the decision (independent from R.224.1(a), not chained off it).
+
+The spawn target — the proceeding rooted by `app.notice` (Berufungseinlegung, RoP.220.1, 2 months) and `app.grounds` (Berufungsbegründung, 4 months from decision) — is what the task brief calls the "UPC infringement-appeal (RoP 220.1(a) main-judgment appeal)" proceeding. Today that's `UPC_APP` (id=11); per t-paliad-204, the code may be renamed before m ingests these proposals, so I refer to it by role only.
+
+### Rule 2.1 — Appeal spawn from UPC_INF
+
+- **Rule code:** `inf.appeal_spawn`
+- **Proceeding type:** UPC_INF (id=8)
+- **Name (DE):** Berufung gegen Endentscheidung
+- **Name (EN):** Appeal against final decision
+- **Party:** both *(either party may appeal an R.118 final decision adverse to them)*
+- **Anchor:** `parent_id = inf.decision` (existing court-set rule "Entscheidung"). The chain: `inf.soc → … → inf.decision (court-set, no statutory date) → inf.appeal_spawn (2 months after service of decision)`. Because `inf.decision` is `IsCourtSet=true` (per `isCourtDeterminedRule` in `internal/services/fristenrechner.go`), the appeal-spawn deadline only becomes a concrete date once the user anchors `inf.decision` via the smart-timeline click-to-anchor mechanism (Slice 2, `POST /api/projects/{id}/timeline/anchor` per memory `ab966313-cae6-49b0-8223-9adb62a64370`).
+- **Duration:** 2, months
+- **Timing:** after
+- **Priority:** optional *(party decides whether to appeal; the 2-month period is statutory once invoked)*
+- **is_court_set:** false *(deadline is statutory once the decision is served)*
+- **condition_expr:** `{"flag":"with_appeal"}` *(only renders when the user has indicated an appeal is contemplated — keeps non-appealing projects' timelines clean)*
+- **Legal source:** `UPC.RoP.220.1`
+- **`rule_code`:** `RoP.220.1.a`
+- **event_type:** `filing`
+- **is_spawn:** true
+- **spawn_proceeding_type_id:** → UPC infringement-appeal proceeding (currently `UPC_APP`, id=11; m picks final code at ingest per t-paliad-204).
+- **spawn_label (DE):** "Berufungsverfahren öffnen"
+- **spawn_label (EN):** "Open appeal proceedings"
+- **Notes:** Spawning into the appeal proceeding creates a child project (or routes into the standalone UPC_APP fristenrechner depending on how spawn rendering works on the project page). The 4-month Statement of grounds period (R.224.2(a), `app.grounds`) is already a root rule on UPC_APP — once the appeal child opens, that timeline takes over. **No need** to also model `app.grounds` as a spawn rule from UPC_INF; the existing UPC_APP root rules cover it.
+- **FLAG (F2.1):** Does the spawn fire on the CCR portion of the decision too? In a `with_ccr=true` UPC_INF, the R.118 final decision adjudicates both the infringement *and* the counterclaim for revocation. Either side may appeal either part. My read: **one spawn covers both** — there's only one R.118 decision, one 2-month window. The Pipeline-A `ccr.appeal` was a relic of the days when CCR was a separate proceeding type. **Recommend dropping the third "ccr.appeal" entirely**, because in the unified UPC_INF (CCR-as-flag) model it would duplicate Rule 2.1. m to confirm.
+- **FLAG (F2.2):** Anchor — should the spawn rule chain off `inf.decision` (court-set, requires anchor-click) or be event-rooted on a `final_decision_service` trigger event (paliad has trigger_event id=88 "Endentscheidung (Zustellung)")? Both work. Chaining on `inf.decision` keeps the rule visually attached to its parent proceeding in the UI; event-rooted is more flexible if the user wants to compute an appeal deadline standalone without a project. Recommend `parent_id = inf.decision` to match how `inf.cost_app` chains off `inf.decision` already.
+- **FLAG (F2.3):** Flag name — `with_appeal` mirrors the existing `with_ccr` / `with_amend` flag naming. Alternative: spawn rules might always fire (no flag), letting the timeline show the appeal window as a "predicted/court-set" placeholder. The latter is closer to what the SmartTimeline projection (`projection_service.go`) already does for cross-proceeding rules per memory `686f0b8c-02ed-4807-8785-b088e3a3e515` § 6 gap 7. If m wants the appeal window to *always* appear after the decision (unconditionally), drop `condition_expr` here and on Rule 2.2.
+
+### Rule 2.2 — Appeal spawn from UPC_REV
+
+- **Rule code:** `rev.appeal_spawn`
+- **Proceeding type:** UPC_REV (id=9)
+- **Name (DE):** Berufung gegen Endentscheidung (Nichtigkeit)
+- **Name (EN):** Appeal against final decision (revocation)
+- **Party:** both
+- **Anchor:** `parent_id = rev.decision` (existing court-set rule "Entscheidung")
+- **Duration:** 2, months
+- **Timing:** after
+- **Priority:** optional
+- **is_court_set:** false
+- **condition_expr:** `{"flag":"with_appeal"}`
+- **Legal source:** `UPC.RoP.220.1`
+- **`rule_code`:** `RoP.220.1.a`
+- **event_type:** `filing`
+- **is_spawn:** true
+- **spawn_proceeding_type_id:** → same UPC infringement-appeal proceeding as Rule 2.1. The UPC CoA hears both INF and REV appeals; in a `with_cci=true` UPC_REV (Verletzungswiderklage / counterclaim-for-infringement), the R.118 decision may also adjudicate the infringement piece, but again it's one decision, one appeal window.
+- **spawn_label (DE):** "Berufungsverfahren öffnen"
+- **spawn_label (EN):** "Open appeal proceedings"
+- **Notes:** Functionally a mirror of Rule 2.1 on the revocation proceeding. Same FLAGs F2.1-F2.3 apply.
+
+### Rule 2.3 — (proposed) NOT drafted: separate `ccr.appeal` from UPC_INF with_ccr
+
+**See FLAG F2.1.** In the unified model, the CCR portion of an UPC_INF decision is appealed via the same R.118 final-decision spawn (Rule 2.1) — a single 2-month window covers infringement, revocation, and patent-amendment claims because they all sit in one R.118 decision. Drafting `ccr.appeal` as a third rule would duplicate Rule 2.1 conditionally (`{"op":"and","args":[{"flag":"with_ccr"},{"flag":"with_appeal"}]}`) and produce a redundant timeline row. **Recommendation: do not seed.** If m disagrees, the rule shape would be:
+
+```
+inf.appeal_spawn_ccr (UPC_INF)
+  condition_expr: {"op":"and","args":[{"flag":"with_ccr"},{"flag":"with_appeal"}]}
+  spawn_label: "Berufung Nichtigkeit öffnen" (specifically the CCR portion)
+```
+
+Only useful if the appeal UI needs to distinguish "appealing the infringement finding" from "appealing the revocation finding". Today's fristenrechner UI doesn't make that distinction; the appeal proceeding handles both.
+
+**Summary for Gap 2:** 2 new spawn rules drafted. 3 FLAGs. The third Pipeline-A relic (`ccr.appeal`) is structurally redundant and recommended **not** to seed.
+
+---
+
+## 3. Gap 3 — `ccr.amend` / `rev.amend` (verification of "safe to drop" claim)
+
+**Status:** No new rules needed. The migration's claim ("superseded by `inf.app_to_amend` / `rev.app_to_amend` — safe to drop") is **confirmed for the patent-amendment scope**. There is a separate concept (R.263 application to amend the case) that has never been modelled and probably shouldn't be — see § 3.2.
+
+### 3.1 Verification — patent-amendment coverage
+
+Pipeline-A's `ccr.amend` and `rev.amend` were both:
+
+- duration_value=0, duration_unit='months', event_type='filing', is_spawn=true, party='claimant'
+- legal_source=NULL, rule_code=NULL
+- source proceeding=AMD (now archived)
+- "Application to Amend Patent" / no German name
+
+These were placeholder spawns into a hypothetical "AMD" (Application to amend the patent) proceeding type that never existed as a real fristenrechner tree. They modelled the concept "filing a patent amendment", not its deadline.
+
+The unified UPC_INF / UPC_REV corpus already covers patent amendment with real deadlines and flag-gated chains:
+
+| Existing rule | Proceeding | Trigger / parent | Duration | Legal source | Flag-gating |
+|---|---|---|---|---|---|
+| `inf.app_to_amend` | UPC_INF | parent=inf.sod | 2 months | UPC.RoP.30.1 | `with_ccr+with_amend` |
+| `inf.def_to_amend` | UPC_INF | parent=inf.app_to_amend | 2 months | UPC.RoP.32.1 | `with_ccr+with_amend` |
+| `inf.reply_def_amd` | UPC_INF | parent=inf.def_to_amend | 1 month | UPC.RoP.32.3 | `with_ccr+with_amend` |
+| `inf.rejoin_amd` | UPC_INF | parent=inf.reply_def_amd | 1 month | UPC.RoP.32.3 | `with_ccr+with_amend` |
+| `rev.app_to_amend` | UPC_REV | parent=rev.defence | 0 months (filed-with-parent) | UPC.RoP.49.2.a | `with_amend` |
+| `rev.def_to_amend` | UPC_REV | parent=rev.app_to_amend | 2 months | UPC.RoP.43.3 | `with_amend` |
+| `rev.reply_def_amd` | UPC_REV | parent=rev.def_to_amend | 1 month | UPC.RoP.32.3 | `with_amend` |
+| `rev.rejoin_amd` | UPC_REV | parent=rev.reply_def_amd | 1 month | UPC.RoP.32.3 | `with_amend` |
+
+The flag-gated chain on UPC_INF (`with_ccr+with_amend`) is the post-2026-05-05 ship from t-paliad-131 PR-2 (memory `ba1517a3-2294-4c58-aeb6-87e82067834d`); the UPC_REV chain (`with_amend` and `with_cci`) is from the same PR. Both fully replace what `ccr.amend` / `rev.amend` ever could have represented.
+
+**Verdict on Gap 3:** "Safe to drop" is correct. **No new rules.**
+
+### 3.2 R.263 — Application to amend the case (not modelled, probably shouldn't be)
+
+R.263 ("Leave to change claim or amend case") is conceptually different from R.30 (Application to amend the patent). R.263 governs amendment of the **pleadings / case** — adding a new infringement allegation, narrowing claims, etc. The current corpus has no R.263 rule.
+
+I'm **not proposing one** because R.263 is purely court-discretionary (R.263.1: "An application may be made by a party at any time to … amend its case … Leave shall be granted only if … the requesting party could not with reasonable diligence have made the application earlier and the amendment will not unreasonably hinder the other party in the conduct of its action"). There is no statutory deadline computable from a fixed anchor — the party files when it needs to, and the court grants or refuses leave by order. Modelling it as a deadline_rule would either:
+
+- (a) Produce a phantom row with no computable date (the existing `is_court_set=true` pattern would technically work but offers no UX value because the deadline is "whenever you need to amend").
+- (b) Produce a misleading row anchored on the SoC date with some heuristic period.
+
+**Recommendation: don't seed.** If m wants R.263 surfaced anywhere, it belongs as a checklist item on the project page, not as a fristenrechner rule.
+
+**FLAG (F3.1):** Confirm "don't model R.263" is acceptable. If R.263 *should* be modelled, what anchor + duration heuristic should it use?
+
+**Summary for Gap 3:** 0 new rules. 1 FLAG. The claim "safe to drop" is verified for patent amendment. R.263 is a separate concept and intentionally left unmodelled.
+
+---
+
+## 4. Gap 4 — `zpo.*` family vs. existing DE_INF / DE_INF_OLG / DE_INF_BGH
+
+**Status:** No new rules needed for `klage`, `vertanz`, `berufung`. **Existing rule `de_inf.erwidg` (Klageerwiderung) has a duration discrepancy worth m's attention.** Task brief's mention of "Klageerweiterung" / "Vertagungsantrag" is a misread of Pipeline-A rule names — those concepts are not in scope here. § 4.1-4.4 verify each Pipeline-A rule; § 4.5 surfaces what *would* be a real gap if m wants ZPO §227 modelled.
+
+### 4.1 `zpo.klage` (Klageerhebung, ZPO §253) — ✓ redundant
+
+Pipeline-A: claimant, 0 months, filing, `§ 253 ZPO`, legal_source=NULL.
+
+Existing rule `de_inf.klage` on DE_INF: claimant, 0 months, filing. Functionally identical as a root rule (a 0-duration "trigger" anchor). Legal source on the existing rule is NULL — could be backfilled to `DE.ZPO.253` as a minor polish, but no new rule needed.
+
+**Verdict: no gap.** *Optional polish:* set `de_inf.klage.legal_source = 'DE.ZPO.253'` (one-line UPDATE; not a new rule). FLAG F4.1.
+
+### 4.2 `zpo.vertanz` (Verteidigungsanzeige, ZPO §276(1) Satz 1) — ✓ redundant
+
+**Task-brief naming note:** the brief described this gap as "Vertagungsantrag" but Pipeline-A's `zpo.vertanz` is actually *Verteidigungsanzeige* (contraction "VertAnz" not "VertA. (Antrag)"). The rule name in the snapshot reads "Verteidigungsanzeige" verbatim. Vertagungsantrag (§ 227 ZPO) is a different concept entirely — see § 4.5.
+
+Pipeline-A: defendant, 2 weeks, filing, `§ 276 Abs. 1 S. 1 ZPO`, deadline_notes "Notfrist ab Zustellung der Klageschrift".
+
+Existing rule `de_inf.anzeige` on DE_INF: defendant, 2 weeks, `DE.ZPO.276.1`, "Anzeige der Verteidigungsbereitschaft". Same period, same legal basis, same party.
+
+**Verdict: no gap.**
+
+### 4.3 `zpo.klageerw` (Klageerwiderung, ZPO §276(1) Satz 2) — ⚠ duration discrepancy
+
+Pipeline-A: defendant, **2 weeks**, filing, `§ 276 Abs. 1 S. 2 ZPO`, legal_source=NULL, deadline_notes "Vom Gericht gesetzt, mindestens 2 Wochen".
+
+Existing rule `de_inf.erwidg` on DE_INF: defendant, **6 weeks**, `DE.ZPO.276.1`, "Klageerwiderung", is_court_set=false.
+
+**This is a substantive discrepancy.** Both rules cite the same statutory anchor (ZPO §276(1) Satz 2), but:
+
+- Pipeline-A modelled the **statutory floor** ("mindestens 2 Wochen") with `is_court_set` implicit (the deadline_notes said "Vom Gericht gesetzt").
+- DE_INF models a **typical court-practice heuristic** (6 weeks is a common Munich/Düsseldorf LG setting, though 4-8 weeks is the realistic range).
+
+The DE_INF rule is **strictly more useful** for a practitioner planning a defence schedule (the 2-week floor is rarely the actual deadline; the court order sets the real date). But it's **technically wrong** to mark `is_court_set=false` because the date *is* set by court order — the 6 weeks is a guess at what the court will set, not a statutory period.
+
+**No new rule needed**, but two corrections are worth flagging on the existing rule:
+
+- **FLAG F4.2 (correctness):** Set `de_inf.erwidg.is_court_set = true`. The deadline date is set by the court's Klageerwiderungsfrist order under §276(1) Satz 2, not by the statute directly. This matches how Schriftsatznachreichung (§296a) was flagged in `docs/proposals/orphan-concepts-2026-05-15.md` § 2.1 FLAG F8.
+- **FLAG F4.3 (heuristic transparency):** 6 weeks vs. the statutory 2-week floor — the deadline_notes (DE) on `de_inf.erwidg` should probably say "Vom Gericht gesetzt, mindestens 2 Wochen (§ 276 Abs. 1 S. 2 ZPO); typische Praxis: 4-8 Wochen" rather than just rendering as a hard 6-week deadline. UX consideration, not a rule-shape question.
+
+Neither change is a new rule; both are PATCH operations on the existing row via `/admin/rules`.
+
+### 4.4 `zpo.berufung` (Berufung, ZPO §517) — ✓ redundant (twice over)
+
+Pipeline-A: both, 1 month, filing, `§ 517 ZPO`, `DE.ZPO.517`, deadline_notes "Notfrist ab Zustellung des vollständigen Urteils".
+
+Existing rules:
+
+- `de_inf.berufung` on DE_INF: both, 1 month, `DE.ZPO.517`. Same shape.
+- `de_inf_olg.berufung` on DE_INF_OLG: both, 1 month, `DE.ZPO.517`. Same shape (covers the OLG-instance entry point).
+
+Either rule covers it. **Verdict: no gap.**
+
+### 4.5 Real gap (if m wants): Vertagungsantrag (ZPO §227)
+
+The task brief mentioned "Vertagungsantrag" by name. Pipeline-A had no Vertagungsantrag rule (the `zpo.vertanz` rule code is a contraction of *Verteidigungsanzeige*, not Vertagungsantrag — see § 4.2). The current corpus has no Vertagungsantrag rule either.
+
+ZPO §227 governs applications to adjourn a hearing ("Aufhebung und Verlegung von Terminen, Vertagung der Verhandlung"). §227.1 requires "erhebliche Gründe", §227.2 gives examples (verhinderter Anwalt etc.), §227.3 restricts adjournment of evidence hearings (Beweisaufnahme). **There is no statutory deadline for filing a Vertagungsantrag** — it's "as soon as the ground arises and, in practice, as early as possible before the hearing date". The application is court-discretionary (§227.1: "kann").
+
+I would **not** recommend modelling Vertagungsantrag as a deadline_rule for the same reason as R.263 in § 3.2: there's no statutory deadline anchor; it's a checklist concept, not a calendar deadline. But m may have a different view — flag F4.4.
+
+**FLAG (F4.4):** Should Vertagungsantrag be modelled? If yes, what anchor + duration? Most natural seed would be `condition_expr={"flag":"with_vertagung"}` on the relevant hearing rule (de_inf.termin, de_null.termin, etc.), is_court_set=true, no duration. But that's an oddly-shaped rule that produces no useful date.
+
+**Summary for Gap 4:** 0 new rules. 4 FLAGs (F4.1-F4.4). The migration's "redundant — safe to drop" claim is confirmed for `klage` / `vertanz` / `berufung`. `klageerw` exposes a discrepancy on the existing `de_inf.erwidg` rule (`is_court_set=false` is wrong; 6-weeks heuristic should be transparent in notes) — both are PATCH operations on the existing row, not new rules. Vertagungsantrag is a separate concept that probably shouldn't be modelled as a deadline_rule.
+
+---
+
+## 5. Track A — Polish UPDATEs on existing rows (no new rules, no legal review)
+
+Distinct from new rules, three existing rows could be PATCH'd via `/admin/rules` to improve correctness or transparency. **None of these are required for the gap-fill to be considered "done"** — they're flagged so they don't get lost if m wants to address them in the same ingest session.
+
+| # | Row | Field | From | To | Reason |
+|---|---|---|---|---|---|
+| P1 | `de_inf.klage` (DE_INF) | `legal_source` | NULL | `DE.ZPO.253` | Polish; matches existing convention (Rule 1.1's `UPC.RoP.19.1` etc.). |
+| P2 | `de_inf.erwidg` (DE_INF) | `is_court_set` | false | true | Correctness; deadline is court-order-set per ZPO §276(1) Satz 2. |
+| P3 | `de_inf.erwidg` (DE_INF) | `deadline_notes` (DE) | (current text) | "Vom Gericht gesetzt, mindestens 2 Wochen (§ 276 Abs. 1 S. 2 ZPO); typische Praxis: 4-8 Wochen" | Transparency; the 6-week duration is a heuristic, not statutory. |
+
+---
+
+## 6. Track B — Genuinely new rule drafts (this proposal's substantive output)
+
+| # | Gap | Rule code | Proceeding (by role) | Source |
+|---|---|---|---|---|
+| 1.1 | 1 (PO) | `inf.prelim` | UPC_INF | RoP 19.1 |
+| 1.2 | 1 (PO) | `rev.prelim` | UPC_REV | RoP 19.1 i.V.m. R.46 |
+| 2.1 | 2 (APP spawn) | `inf.appeal_spawn` | UPC_INF, spawn → UPC infringement-appeal proceeding | RoP 220.1(a) / R.224.1(a) |
+| 2.2 | 2 (APP spawn) | `rev.appeal_spawn` | UPC_REV, spawn → UPC infringement-appeal proceeding | RoP 220.1(a) / R.224.1(a) |
+
+**Total new rules: 4.** Plus 3 optional polish PATCHes in § 5. None of the proposed rules introduce new flag-name conventions (other than `with_po` and `with_appeal`, which mirror existing `with_ccr` / `with_amend` / `with_cci`).
+
+### Future-work (not this proposal)
+
+- Order-appeals spawn (R.220.2 / R.220.3) from UPC_INF / UPC_REV / UPC_PI → UPC_APP_ORDERS (15-day track). Today UPC_APP_ORDERS has only standalone root rules.
+- Cost-decision-appeal spawn (R.221.1) from UPC_INF / UPC_REV → UPC_COST_APPEAL.
+- CCR-defendant PO (FLAG F1.4): claimant's 1-month PO window when receiving SoD-with-CCR — only if confirmed against real case law or m's read.
+- R.263 (case amendment) and ZPO §227 (Vertagungsantrag): both court-discretionary, no statutory deadline — recommend leaving unmodelled (FLAGs F3.1, F4.4).
+- DE_NULL / DE_NULL_BGH appeal spawns: PatG §110 chains DE_NULL → DE_NULL_BGH (Berufung BGH). Currently DE_NULL_BGH is a standalone tree rooted on `de_null_bgh.urteil_bpatg`. Same pattern as the UPC spawn gap. Out of brief scope but worth a parallel proposal.
+
+---
+
+## 7. Open questions / FLAGs index
+
+For convenience, all `**FLAG**`-marked items in one place. m's decision is needed on each before `/admin/rules` ingest of the corresponding rule (or rule edit).
+
+| ID | Section | Question |
+|---|---|---|
+| F1.1 | § 1.1 | Flag name for Preliminary Objection — `with_po` vs `with_preliminary_objection` vs `prelim`. |
+| F1.2 | § 1.1 | Priority for PO — `optional` (recommended) vs `recommended` (always-surface as sanity-check chip). |
+| F1.3 | § 1.2 | Legal-source citation for UPC_REV PO — `UPC.RoP.19.1` (substantive) vs `UPC.RoP.46` (operative). Recommend substantive. |
+| F1.4 | § 1.2 | Add a third PO rule for CCR-defendant (party=claimant, fires when `with_ccr=true`)? |
+| F2.1 | § 2.1 | Recommend **not seeding** `ccr.appeal` as a third rule — CCR appeal is covered by `inf.appeal_spawn` (one R.118 decision, one window). Confirm. |
+| F2.2 | § 2.1 | Anchor for spawn — `parent_id = inf.decision` (chain) vs `trigger_event_id = 88 final_decision_service` (event-rooted). Recommend chain. |
+| F2.3 | § 2.1 | Flag-gated (`with_appeal`) vs always-rendered. Recommend flag-gated to keep non-appealing timelines clean; SmartTimeline's "predicted" rendering of cross-proceeding rules is the alternative. |
+| F3.1 | § 3.2 | R.263 (case amendment) — confirm not modelled as a deadline_rule. |
+| F4.1 | § 4.1 | Polish P1: backfill `de_inf.klage.legal_source = 'DE.ZPO.253'`? |
+| F4.2 | § 4.3 | Polish P2: set `de_inf.erwidg.is_court_set = true`? |
+| F4.3 | § 4.3 | Polish P3: improve `de_inf.erwidg.deadline_notes` to expose the 6-week heuristic vs the 2-week statutory floor? |
+| F4.4 | § 4.5 | Vertagungsantrag (ZPO §227) — confirm not modelled. |

+## 9. What's next (if m approves)
+
+1. **Decide the 12 FLAGs in § 7** (mostly flag names, priorities, and the three PATCH operations on existing rows). None require legal-side research — they're product/UX calls.
+2. **Confirm the appeal target's final proceeding-code** post-t-paliad-204 rename. Until then, ingest using whatever code lives at id=11 (currently `UPC_APP`) and rename via mig if t-paliad-204 lands with a different code.
+3. **Ingest the 4 new rules** via `/admin/rules` POST (Slice 11a backend, Slice 11b frontend). Each goes into `lifecycle_state='draft'` first. Promote to `published` after spot-checking via the calculator preview endpoint with a test project (e.g. UPC_INF with `with_po=true` should show the new `inf.prelim` row 1 month after the trigger date).
+4. **Optionally apply the 3 PATCHes in § 5** in the same session.
+5. **Verify spawn rendering** end-to-end — the spawn_proceeding_type_id column is unused in live data today, so this is the first real consumer. The SmartTimeline projection (per `internal/services/projection_service.go`, memory `686f0b8c-…`) early-returns on spawn rules when "we don't have that rule in our map" — that code path needs to actually render a spawn row now, not no-op. May require a Slice 7 follow-up tweak in `projection_service.go` to honour `spawn_proceeding_type_id` and surface the appeal proceeding's root deadline as a spawned child row.
+
+**Estimated corpus delta after ingest:** Track B = 4 new rules → `paliad.deadline_rules` row count grows from 249 to **253**. Track A polish = 3 row-level PATCHes (no row count change). One new `is_spawn=true` row goes live for the first time, exercising the previously-unused `spawn_proceeding_type_id` wiring.

+# Legal-citation Backfill Proposals — t-paliad-208 (Workstream A)
+
+**Date:** 2026-05-18
+**Author:** huygens (researcher)
+**Status:** DRAFT — for m's review, not yet migrated
+**Branch:** `mai/huygens/workstream-a-backfill`
+**Adjacent:** parallel-track with t-paliad-209 (workstream B — `code` rename + UI cleanup; different fields, no overlap)
+**Successor:** mig 097 will UPDATE the rows m approves; backup snapshot `deadline_rules_pre_097`

+
+## 0. Read-this-first
+
+### 0.1 What this doc is
+
+Today's audit (paliadin/head, 2026-05-18) found that **130 of 213 active+published rows in `paliad.deadline_rules`** have `rule_code IS NULL`, and 122 have `legal_source IS NULL`. The internal slug field `code` (e.g. `inf.sod`, `de_null.berufung`) had been mistaken for a legal citation; it is just the per-proceeding submission identifier. The actual RoP / ZPO / EPÜ / PatG / UPCA citation belongs in `rule_code` (display form) + `legal_source` (structured locator).
+
+This document proposes a citation per rule. m approves; head re-tasks for migration 097.
+
+### 0.2 Field convention (profiled from the 83 already-populated rows)
+
+| Field | Purpose | Examples from live data |
+|---|---|---|
+| `rule_code` | **Human display form**, what we'd write in a brief | `§ 276 ZPO`, `§ 110 PatG`, `Art. 99 EPÜ`, `R. 71(3) EPÜ`, `R. 116 EPÜ`, `RPBA Art. 12`, `RoP.029.a`, `RoP.220.1.a`, `RoP.151`, `RoP.49.1` |
+| `legal_source` | **Structured locator** (forum-prefixed, no zero padding) for cross-system joins / lex extraction | `DE.ZPO.276.1`, `DE.PatG.111.1`, `EU.EPÜ.108`, `EU.EPC-R.71.3`, `EU.RPBA.12.1.c`, `UPC.RoP.29.a`, `UPC.RoP.220.1` |
+
+**Sub-conventions observed in live data**
+
+- `legal_source` prefixes: `DE.<statute>.<n>.<para>`, `EU.EPÜ.<n>.<para>`, `EU.EPC-R.<n>.<para>`, `EU.RPBA.<n>.<para>.<letter>`, `UPC.RoP.<n>.<sub>`.
+- `rule_code` padding for UPC RoP is **inconsistent today**: rules below 100 are mostly 3-digit padded (`RoP.029.a`, `RoP.030.1`, `RoP.049.2.a`, `RoP.056.1`) but `rev.defence` carries an un-padded `RoP.49.1`. Rules ≥100 are never padded (`RoP.137.2`, `RoP.220.1`).
+  - **Proposed normalization:** 3-digit pad for rules <100, no pad for ≥100. mig 097 should also normalize `RoP.49.1 → RoP.049.1` (1 outlier row, `rev.defence`) as a side-fix. m to confirm.
+- `legal_source` for UPC RoP **never** pads (`UPC.RoP.29.a`, not `UPC.RoP.029.a`). I follow that.
+
+### 0.3 Triage philosophy — events vs. deadlines
+
+Of the 130 NULL-rule_code rows, 53 carry a `proceeding_type_id` and 77 are orphans (`proceeding_type_id IS NULL`, also `code IS NULL`). Within the proceeding-typed bucket, most are **event markers** (zero `duration_value`, `event_type ∈ {hearing, decision, filing}`) that anchor other deadlines rather than computing one of their own.
+
+I classify each row as one of:
+
+| Category | Treatment | Examples |
+|---|---|---|
+| **Deadline** (positive duration, fires off an anchor) | Cite the operative procedural norm. Confidence usually HIGH. | `inf.sod` Klageerwiderung 3 months → RoP.23 |
+| **Constitutive event** (zero duration, but a statute defines it) | Cite the constitutive norm (matches existing convention: `de_inf.klage` already has `DE.ZPO.253`). Confidence HIGH where the norm is canonical. | Klageerhebung → § 253 ZPO; Anmeldung EP → Art. 75 EPÜ; Klage UPC → RoP.13.1 |
+| **Service / trigger event** (zero duration, third-party delivery) | Cite the service norm (§ 317 ZPO etc.) with MEDIUM confidence — these are anchor events for downstream timers, not deadlines on a party. m may prefer NULL here. **FLAG.** | `de_inf_olg.urteil_lg` Zustellung LG-Urteil |
+| **Court-scheduled event** (hearing, judgment-issuance) | Either NULL (recommended) or cite the general norm authorising the court to schedule. **FLAG.** | Mündliche Verhandlung BGH; OLG-Urteil |
+| **Court-set duration** (positive duration but `is_court_set=true`, or local practice) | Cite the framing norm (e.g. § 273 ZPO for ZPO patent practice), MEDIUM, FLAG. | `de_inf.replik` 4 weeks (LG patent practice) |
+
+**Where I am proposing NULL**, the row stays as-is on the DB side (mig 097 simply doesn't touch it). The FLAG list at the bottom of this doc enumerates every NULL proposal so m can override with an explicit citation if desired.
+
+### 0.4 Counts
+
+- 130 rows in scope (rule_code IS NULL; is_active=true; lifecycle_state='published')
+- 53 proceeding-typed + 77 orphan (no proceeding_type_id, no code)
+- 8 rows already carry a `legal_source` — those are **easy wins**: only `rule_code` needs proposing
+- ~ 40 HIGH-confidence proposals
+- ~ 35 MEDIUM-confidence proposals
+- ~ 55 FLAG entries (court-scheduled events, combined-pleading rows, ambiguous orphans)
+
+The orphan bucket carries a noticeable number of **duplicates** (six "Mängelbeseitigung / Zahlung" rows, two "Beginn des Hauptsacheverfahrens", two "Antrag auf Patentänderung", etc.). Those are likely vestiges of older Fristenrechner pipelines; backfilling them with the same citation is fine, but m may want a separate dedup pass (out of scope here; flag in § 4).
+
+---
+
+## 1. Easy wins — rows with `legal_source` already set, `rule_code` missing (8)
+
+For these, the structured locator is already in the DB; only the display form is missing.
+
+| id | code / name | duration | existing `legal_source` | proposed `rule_code` | conf |
+|---|---|---|---|---|---|
+| `1f532c82…` | `de_inf.klage` / Klageerhebung | event | `DE.ZPO.253` | `§ 253 ZPO` | HIGH |
+| `20254f4e…` | (orphan) Einspruch gegen Versäumnisurteil | 2 weeks | `DE.ZPO.339.1` | `§ 339 ZPO` | HIGH |
+| `3c36f149…` | (orphan) Schriftsatznachreichung (§ 296a ZPO) | 3 weeks | `DE.ZPO.296a` | `§ 296a ZPO` | HIGH |
+| `f1099cf6…` | (orphan) Weiterbehandlungsantrag (Art. 121 EPÜ) | 2 months | `EU.EPC-R.135.1` | `R. 135 EPÜ` | HIGH |
+| `c24d494c…` | (orphan) Wiedereinsetzungsantrag (§ 123 PatG) | 2 months | `DE.PatG.123.2` | `§ 123 PatG` | HIGH |
+| `d40d9be7…` | (orphan) Wiedereinsetzungsantrag (§ 233 ZPO) | 2 weeks | `DE.ZPO.234.1` | `§ 234 ZPO` | HIGH |
+| `23c6f445…` | (orphan) Wiedereinsetzungsantrag (Art. 122 EPÜ) | 2 months | `EU.EPC-R.136.1` | `R. 136 EPÜ` | HIGH |
+| `b588fa64…` | (orphan) Wiedereinsetzungsantrag (DPMA) | 2 months | `DE.PatG.123.2` | `§ 123 PatG` | HIGH |
+
+**Naming note on the two Wiedereinsetzung-`§ 123 PatG` rows.** Both `c24d494c…` ("§ 123 PatG" name) and `b588fa64…` ("DPMA" name) map to the same statute — § 123 PatG (Wiedereinsetzung) applies to all DPMA-Verfahren, so the duplication is a pure naming choice. mig 097 fills both; potential dedup is a separate question (§ 4 FLAG-A).
+

+
+## 2. Proceeding-typed rows (53)
+
+Grouped by `proceeding_types.code`. Within each group: alphabetical by `code`.
+
+### 2.1 `upc.inf.cfi` — Verletzungsverfahren CFI (4 rules)
+
+| code | name | duration | event_type | proposed `rule_code` | proposed `legal_source` | source-of-truth | conf |
+|---|---|---|---|---|---|---|---|
+| `inf.decision` | Entscheidung | event | decision | *(NULL)* | *(NULL)* | RoP.118 — but this is the court's own decision, not a party deadline | **FLAG-B** |
+| `inf.interim` | Zwischenverfahren | event | hearing | *(NULL)* | *(NULL)* | RoP.101 ff. governs interim procedure; not a single norm | **FLAG-B** |
+| `inf.oral` | Mündliche Verhandlung | event | hearing | *(NULL)* | *(NULL)* | RoP.111-117 (oral procedure); court-scheduled | **FLAG-B** |
+| `inf.soc` | Klageerhebung (Statement of claim) | event | filing | `RoP.013.1` | `UPC.RoP.13.1` | RoP.13 — Statement of claim contents | HIGH |
+
+### 2.2 `upc.rev.cfi` — Nichtigkeitsverfahren CFI (6 rules)
+
+| code | name | duration | event_type | proposed `rule_code` | proposed `legal_source` | source-of-truth | conf |
+|---|---|---|---|---|---|---|---|
+| `rev.app` | Nichtigkeitsklage | event | filing | `RoP.042` | `UPC.RoP.42` | RoP.42 — Statement for revocation | HIGH |
+| `rev.decision` | Entscheidung | event | decision | *(NULL)* | *(NULL)* | court-issued, not a party deadline | **FLAG-B** |

+| `rev.reply` | Replik | 2 months | filing | `RoP.052` | `UPC.RoP.52` | RoP.52 — Reply to defence in revocation | MED (**FLAG-C**: duration vs. norm) |
+| `rev.rejoin` | Duplik | 2 months | filing | `RoP.052` | `UPC.RoP.52` | RoP.52 — Rejoinder | MED (**FLAG-C**: duration vs. norm) |
+
+**FLAG-C:** RoP.52(1) sets the reply to 2 months but RoP.52(2) sets the rejoinder to 1 month from service of the reply. m's `rev.rejoin` says 2 months — verify whether the rule duration is correct or whether `RoP.52.2` (1 month) is the right citation. Cross-check with the existing `rev.rejoin_cci` row which uses RoP.056.4 (cci context); the main-pleadings rejoinder lives in RoP.52.

+## 4. FLAG summary — items needing m's call
+
+| FLAG | Topic | Count | Decision needed |
+|---|---|---|---|
+| **A** | Genuine duplicate orphan rows (same name + dur + citation) | ~10 | Confirm the dedup pass should happen in mig 097 (or a follow-up). Recommended: leave duplicates in place for mig 097 (fills all of them with the same citation); dedup separately so the rule-resolution semantics don't drift. |
+| **B** | Court-scheduled / court-issued event rows (Mündliche Verhandlung, Urteil, Entscheidung) | ~22 | Confirm NULL is the right default. Alternative: cite the framing norm with a "context" note. |
+| **C** | UPC RoP duration vs. norm mismatch (`rev.reply` / `rev.rejoin` / `app.response`) | 3 | Verify the rule durations are correct as stored — proposed citations are canonical but rule duration may be from an older RoP version. |
+| **D** | German LG patent practice: 4-week replik/duplik (court-set) | 2 | Confirm `§ 273 ZPO` is the cite m wants (no statutory period, framing norm only). |
+| **E** | Service / trigger-event citations (`§ 317 ZPO`, `R. 111 EPÜ` etc.) | 6 | These are anchor-events for downstream timers, not deadlines. Confirm whether to cite (current proposal) or leave NULL. |
+| **F** | Combined-pleading orphan rows (one row = several norms) | 5 | Confirm one citation is acceptable, or whether the rows should be split before mig 097 (out of scope here). |
+| **G** | Twin "Antrag auf Patentänderung" orphans (2-mo, identical name) | 2 | Confirm one is infringement-context (`RoP.30.1`), the other revocation-context (`RoP.49.2.a`). |
+| **H** | RoP sub-paragraph uncertainty (current text vs. older version) | ~8 | Spot-check against current published RoP; my citations are canonical but small `.x` numbers may need a tweak. |
+| **I** | Negative-declaration track (no single UPC norm) | 3 | Confirm citing `RoP.69` (procedure-by-analogy) vs. leaving NULL. |
+| **J** | Orphan with unclear scope | 3 | `d124c95b…` (Aufhebung Entscheidung des Amtes), `002c2ba7…` (Folgemaßnahmen Validitätsentscheidung), `902cc5d5…` (Klärung Übersetzungsfragen). m to identify which UPC norm. |
+
+---
+
+## 5. Side-fix (recommend bundled in mig 097)
+
+**RoP-display normalization**: `rev.defence` currently carries `rule_code = "RoP.49.1"`. All other RoP rules under 100 use 3-digit padding (`RoP.029.a`, `RoP.049.2.a` etc.). mig 097 should normalize `RoP.49.1 → RoP.049.1` in that one row, while filling the 130 NULL rows with consistently padded values.
+
+```sql
+-- side-fix candidate
+UPDATE paliad.deadline_rules
+   SET rule_code = 'RoP.049.1'
+ WHERE rule_code = 'RoP.49.1'
+   AND code      = 'rev.defence';   -- only one row; idempotent
+```
+
+This is opt-in; m to confirm before mig 097 ships.
+
+---
+
+## 6. Migration 097 hints (for the coder who writes it)
+
+**Shape m has asked for:**
+
+- `UPDATE paliad.deadline_rules SET rule_code = …, legal_source = … WHERE id = … AND rule_code IS NULL AND legal_source IS [NULL|expected];`
+- Idempotent: `WHERE rule_code IS NULL` (or `IS DISTINCT FROM`) guard so re-applying is a no-op.
+- Backup snapshot: `CREATE TABLE paliad.deadline_rules_pre_097 AS SELECT * FROM paliad.deadline_rules` before any UPDATEs.
+- Wrap in `audit_reason = 't-paliad-208 legal-citation backfill'` (matches `paliad.audit_log` pattern used elsewhere).
+- Touch only the m-approved rows from § 1, § 2, § 3 — FLAG rows (those with `*(NULL)*` in the proposed columns) stay untouched until m resolves them.
+- Side-fix § 5 (`RoP.49.1 → RoP.049.1`) only if m confirms.
+
+**Counts the migration should match (assuming m approves all HIGH proposals as-is):**
+
+- Easy wins (§ 1): 8 `rule_code` UPDATEs (legal_source already set)
+- Proceeding-typed HIGH/MED proposals (§ 2): ~25 rows
+- Orphan HIGH/MED proposals (§ 3): ~50 rows
+- Total expected `rule_code` writes: ~83 rows
+- Total expected `legal_source` writes: ~75 rows (8 of the easy wins already have one)
+- FLAG rows left NULL: ~47 rows pending m's decisions
+
+---
+
+## 7. Open questions for m
+
+1. **NULL for event-markers (FLAG-B):** confirm NULL is correct for the 22 court-scheduled / court-issued event rows. If m wants citations there too, I'll do a second pass.
+2. **Trigger-event citations (FLAG-E):** apply `§ 317 ZPO` to LG/OLG service rows, or leave NULL?
+3. **Duplicates (FLAG-A):** mig 097 fills duplicates with the same citation; do you want a separate dedup pass scheduled (filing `t-paliad-21x`) or is the duplicate count acceptable for now?
+4. **Combined-pleading orphans (FLAG-F):** keep one citation per row, or split each row into N rows before mig 097?
+5. **Negative-declaration track (FLAG-I):** cite `RoP.69` by analogy, or leave NULL?
+6. **Side-fix (§ 5):** normalize the one `RoP.49.1` outlier as part of mig 097?
+
+Once m answers, head can re-task this same worker (or a fresh coder) to write mig 097 against the approved proposals.

+
+m's task description (and pauli's audit dated 2026-05-13) cited **nine** orphan concepts with `rule_count=0`. Today's live `paliad` DB shows **five**:
+
+| # | Slug | Party | Category |
+|---|------|-------|----------|
+| 1 | `wiedereinsetzung` | both | submission |
+| 2 | `schriftsatznachreichung` | both | submission |
+| 3 | `versaeumnisurteil-einspruch` | defendant | submission |
+| 4 | `weiterbehandlung` | claimant | submission |
+| 5 | `counterclaim-for-revocation` | defendant | submission |
+
+Four of the audit's nine were almost certainly seeded between 2026-05-13 and 2026-05-15 by Slice 10 (migration 090, fuzzy backfill) and the Slice-11 admin rule-editor work. `notice-of-defence-intention` is one of them: today's `DE_INF` corpus contains `de_inf.anzeige` (Anzeige der Verteidigungsbereitschaft, ZPO §276.1) linked to its own concept, which removes it from the orphan list.
+
+**FLAG (count discrepancy):** I drafted proposals for the **5** remaining orphans, not 9. m should confirm whether the other 4 audit-named concepts were intentionally seeded or whether something else is going on before treating this as "done".
+
+### 0.1 A second, more important framing problem
+
+The orphan query `deadline_concepts.id NOT IN (SELECT concept_id FROM deadline_rules)` counts only **direct** `concept_id` linkages on `paliad.deadline_rules`. But the schema has two alternate rooting columns: `proceeding_type_id` (Pipeline A) and `trigger_event_id` (Pipeline C). The Pipeline-C migration (Slice 4, m/paliad#…) imported 77 event-rooted rules from `paliad.event_deadlines` but left their `concept_id` **NULL** on the unified `deadline_rules` table — even when the source trigger event had a matching `concept_id` slug already set on `paliad.trigger_events`.
+
+Concretely, the following rules **already exist** in `paliad.deadline_rules` but lack `concept_id`:
+
+| Rule name | `trigger_event_id` | Trigger event code | Owning concept (via `trigger_events.concept_id` slug) |
+|---|---|---|---|
+| Wiedereinsetzungsantrag (§ 123 PatG) | 200 | `wegfall_hindernisses_de_patg` | `wiedereinsetzung` |
+| Wiedereinsetzungsantrag (§ 233 ZPO) | 201 | `wegfall_hindernisses_de_zpo` | `wiedereinsetzung` |
+| Wiedereinsetzungsantrag (Art. 122 EPÜ) | 202 | `wegfall_hindernisses_eu_epc` | `wiedereinsetzung` |
+| Wiedereinsetzungsantrag (DPMA) | 203 | `wegfall_hindernisses_dpma` | `wiedereinsetzung` |
+| Einspruch gegen Versäumnisurteil (§ 339 ZPO) | 204 | `zustellung_versaeumnisurteil` | `versaeumnisurteil-einspruch` |
+| Schriftsatznachreichung (§ 296a ZPO) | 205 | `ende_muendl_verhandlung` | `schriftsatznachreichung` |
+| Weiterbehandlungsantrag (Art. 121 EPÜ) | 206 | `mitteilung_rechtsverlust_eu` | `weiterbehandlung` |
+| *(none yet)* | 207 | `wegfall_hindernisses_upc` | `wiedereinsetzung` |
+
+**Net effect:** four of the five "orphan" concepts already have at least one workable rule — it is just disconnected from the concept by a NULL `concept_id`. The genuine coverage gap is much smaller than "5 concepts × ~5 rules each = 25 rules to draft". Practical Phase-3-Slice-12 work splits into:
+
+- **Track A (linkage, no legal review needed):** `UPDATE paliad.deadline_rules SET concept_id = … WHERE trigger_event_id IN (200,201,202,203,204,205,206)`. 7 rows, zero new legal substance. See § 6 of this doc.
+- **Track B (new rule drafts, this doc's main body):** UPC R.320 Wiedereinsetzung (`trigger_event_id=207` truly has no rule yet), proceeding-rooted variants for the four jurisdictions where having a rule under the UPC_INF / DE_INF / EPA_OPP / DPMA_OPP umbrella makes the cascade complete, plus the schema-correct way to resolve `counterclaim-for-revocation` (which is intentionally encoded as flag-gated UPC_INF rules and probably should not get fresh rules at all).
+
+**FLAG (audit framing):** I recommend the orphan KPI be redefined as "concepts where NO rule references the concept, **directly via `deadline_rules.concept_id` OR transitively via `deadline_rules.trigger_event_id → trigger_events.concept_id`**". Until that happens, the orphan list will keep over-reporting work that has already been done in another column. The Phase 2 design (`docs/design-fristen-phase2-2026-05-15.md` § 3 Step C) anticipates dropping the `paliad.trigger_events` table entirely in Slice 9 and copying `concept_id` onto `deadline_rules` at that point — once that migration runs, the discrepancy resolves itself.
+
+### 0.2 Convention notes
+
+- Rule **code** column (`paliad.deadline_rules.code`) uses `<proceeding_short>.<action>` for proceeding-rooted rules (e.g. `inf.sod`, `de_inf.berufung`). For event-rooted rules `code` is NULL today; I follow that pattern.
+- **Anchor semantics** (audit § 4): `parent_id NULL + duration_value=0` = root anchor / court-set absolute. `parent_id NULL + duration_value>0 + trigger_event_id` = event-rooted, anchored to the trigger event's date. `parent_id NOT NULL` = chained off another rule.
+- **Priority values** (post-Slice-3): `mandatory` | `recommended` | `optional` | `informational`. Wiedereinsetzung-class rules are conceptually `optional` for the user (they may decide not to file), but the legal-source side is mandatory once invoked. I tag them `optional` with the legal source making the obligation conditional — m to confirm.
+- **`is_court_set`** is true when the deadline date is set by court order rather than computed from a statutory period. For Schriftsatznachreichung this is the relevant case; for Wiedereinsetzung/Weiterbehandlung it's false (statutory period).
+- **`legal_source`** uses the existing convention seen on live rules (`UPC.RoP.29.a`, `DE.ZPO.234.1`, `EU.EPC-R.135.1`, `EU.EPÜ.99.1`).

+
+**Concept ID:** `00b737bf-58a6-4f41-9650-ac3f2e7079e8`
+**Party:** both · **Category:** submission
+**Linked event_categories (cascade leaves):**
+- `cms-eingang.gericht.rechtsverlust-epa` (Mitteilung über Rechtsverlust, EPA)
+- `frist-verpasst.de-patg` (DE Patentverfahren, PatG §123)
+- `frist-verpasst.de-zpo` (DE Zivilverfahren, ZPO §233)
+- `frist-verpasst.dpma` (DPMA, PatG §123)
+- `frist-verpasst.epa` (EPA, Art. 122 EPÜ)
+- `frist-verpasst.upc` (UPC, R.320 RoP)
+
+**Existing trigger-event-rooted rules:** trigger events 200/201/202/203 already have rules in `paliad.deadline_rules` (DE PatG, DE ZPO, EPC, DPMA respectively). Only te 207 (UPC R.320) has no rule yet. See § 6 for the linkage UPDATE that brings the existing four into the concept's rule list.
+
+**Drafts below:**
+
+### Rule 1.1 — UPC R.320 Wiedereinsetzungsantrag
+
+- **Rule code:** `upc.wiedereinsetzung` *(proceeding-rooted) ORalt. NULL code + `trigger_event_id=207` (event-rooted, matches pattern of te 200-206 rules)*
+- **Proceeding type:** UPC_INF (id=8) — primary. Also relevant for UPC_REV (9), UPC_PI (10), UPC_APP (11), UPC_DAMAGES (17), UPC_DISCOVERY (18), UPC_COST_APPEAL (19), UPC_APP_ORDERS (20). **FLAG:** Wiedereinsetzung applies across the full UPC corpus; m to decide whether to (a) seed one event-rooted rule referencing te 207 — pattern matches the existing four jurisdictions — or (b) seed seven proceeding-rooted clones. Recommend (a): cleaner, mirrors the pattern already set for DE/EPC/DPMA, and Slice 9's table-drop migration in Phase 2 will canonicalise it.
+- **Name (DE):** Wiedereinsetzungsantrag (R. 320 RoP UPC)
+- **Name (EN):** Application for re-establishment of rights (UPC R.320 RoP)
+- **Party:** both (claimant or defendant, whoever missed)
+- **Anchor:** `trigger_event_id = 207` (`wegfall_hindernisses_upc`)
+- **Duration:** 2, months
+- **Timing:** after
+- **Priority:** optional *(filing is at the party's discretion — see § 0.2)*
+- **is_court_set:** false
+- **condition_expr:** NULL
+- **Legal source:** `UPC.RoP.320.1`
+- **Notes:** UPC R.320.1 sets a 2-month window from removal of the cause of non-compliance, capped by an absolute 1-year limit from expiry of the missed period (see Rule 1.2 below). The omitted act must be completed within the same 2-month window (R.320.2). Court fee per R.150(1)(p). UI may want to show the 1-year backstop as a sibling "Achtung" line; that is a renderer decision, not a separate rule.
+
+### Rule 1.2 — UPC R.320 — 1-Jahres-Ausschlussfrist (informational)
+
+- **Rule code:** `upc.wiedereinsetzung.cutoff` (or trigger-rooted with a sibling `sequence_order` after Rule 1.1)
+- **Proceeding type:** same as Rule 1.1
+- **Name (DE):** Absolute Ausschlussfrist Wiedereinsetzung (1 Jahr)
+- **Name (EN):** Absolute cut-off for re-establishment (1 year)
+- **Party:** both
+- **Anchor:** the **missed** deadline's date — not `wegfall_hindernisses_upc`. **FLAG:** Today's `trigger_events` model can't express "anchor = the missed deadline" because the trigger fires on removal of cause, not on the missed deadline. Either (a) add a new trigger event `frist_versaeumt_upc` and root this rule there, or (b) make this an `informational` UI-only rule rendered by the renderer next to Rule 1.1 with no real anchor. Recommend (b) for now; (a) is a Phase-3 schema follow-up.
+- **Duration:** 12, months
+- **Timing:** after
+- **Priority:** informational
+- **is_court_set:** false
+- **condition_expr:** NULL
+- **Legal source:** `UPC.RoP.320.1` (second half: "but at the latest within one year of the expiry of the unobserved time limit")
+- **Notes:** Cosmetically important — practitioners forget the cut-off. Keep as informational rendering until the schema supports two-anchor rules.
+
+### Rule 1.3 — EPC Art. 122 / R.136 Wiedereinsetzungsantrag (EPA)
+
+- **Rule code:** *(event-rooted; NULL `code`, matches existing pattern for te 200-203)*
+- **Proceeding type:** NULL (or EPA_OPP=14 / EPA_APP=15 / EP_GRANT=16 if proceeding-rooted)
+- **Name (DE):** Wiedereinsetzungsantrag (Art. 122 EPÜ)
+- **Name (EN):** Petition for re-establishment of rights (EPC Art.122)
+- **Party:** both
+- **Anchor:** `trigger_event_id = 202` (`wegfall_hindernisses_eu_epc`)
+- **Duration:** 2, months
+- **Timing:** after
+- **Priority:** optional
+- **is_court_set:** false
+- **condition_expr:** NULL
+- **Legal source:** `EU.EPC-R.136.1`
+- **Notes:** **DUPLICATE of existing rule** `23c6f445-4ed2-4ade-8ea0-c4ab6b364bb6` — already in `deadline_rules`, just missing `concept_id`. See § 6 linkage UPDATE; do not double-seed.
+
+### Rule 1.4 — EPC R.136 — 1-Jahres-Ausschlussfrist
+
+- **Rule code:** as Rule 1.2 pattern
+- **Name (DE):** Absolute Ausschlussfrist Wiedereinsetzung EPA (1 Jahr)
+- **Name (EN):** Absolute cut-off for re-establishment, EPC (1 year)
+- **Party:** both
+- **Anchor:** missed-deadline date (same FLAG as Rule 1.2 — schema follow-up)
+- **Duration:** 12, months
+- **Timing:** after
+- **Priority:** informational
+- **is_court_set:** false
+- **condition_expr:** NULL
+- **Legal source:** `EU.EPC-R.136.1` (second sentence)
+- **Notes:** R.136(1) third sentence carves out a special **2-month** cut-off for restoration of priority (Art. 87(1) in conjunction with R.136(1)). m may want a separate rule 1.4b for that priority variant; flagging rather than auto-resolving.
+
+### Rule 1.5 — DE PatG §123 Wiedereinsetzungsantrag (DPMA + national)
+
+- **Rule code:** event-rooted, te=200 (PatG) and te=203 (DPMA)
+- **Name (DE):** Wiedereinsetzungsantrag (§ 123 PatG)
+- **Name (EN):** Petition for re-establishment of rights (PatG §123)
+- **Party:** both
+- **Anchor:** `trigger_event_id = 200` (`wegfall_hindernisses_de_patg`) — for general DE PatG context — AND `trigger_event_id = 203` (`wegfall_hindernisses_dpma`) — for DPMA-specific context.
+- **Duration:** 2, months
+- **Timing:** after
+- **Priority:** optional
+- **is_court_set:** false
+- **condition_expr:** NULL
+- **Legal source:** `DE.PatG.123.2`
+- **Notes:** **DUPLICATE of existing rules** `c24d494c-…` (te 200) and `b588fa64-…` (te 203). Linkage only — see § 6.
+
+### Rule 1.6 — DE PatG §123 — 1-Jahres-Ausschlussfrist
+
+- **Rule code:** as 1.2/1.4 pattern (informational)
+- **Name (DE):** Absolute Ausschlussfrist Wiedereinsetzung PatG (1 Jahr)
+- **Name (EN):** Absolute cut-off for re-establishment, PatG (1 year)
+- **Party:** both
+- **Anchor:** missed-deadline date (schema FLAG as 1.2)
+- **Duration:** 12, months
+- **Timing:** after
+- **Priority:** informational
+- **is_court_set:** false
+- **condition_expr:** NULL
+- **Legal source:** `DE.PatG.123.2` (Satz 4)
+- **Notes:** PatG §123(2) Satz 4: "Innerhalb eines Jahres nach Ablauf der versäumten Frist ist keine Wiedereinsetzung mehr möglich." Same as PatG also for DPMA proceedings.
+
+### Rule 1.7 — DE ZPO §233 Wiedereinsetzungsantrag (Notfrist, 2 Wochen)
+
+- **Rule code:** event-rooted, te=201
+- **Name (DE):** Wiedereinsetzungsantrag — Notfrist (§ 234 Abs. 1 S. 1 ZPO)
+- **Name (EN):** Petition for re-establishment of rights — Notfrist (ZPO §234(1) sentence 1)
+- **Party:** both

+- **Duration:** 2, weeks
+- **Timing:** after
+- **Priority:** optional
+- **is_court_set:** false
+- **condition_expr:** NULL — but see Rule 1.8 for the 1-month variant.
+- **Legal source:** `DE.ZPO.234.1`
+- **Notes:** **DUPLICATE of existing rule** `d40d9be7-…` — linkage only. ZPO §234(1) sentence 1: 2 weeks for Notfristen (Berufungsfrist, Revisionsfrist, Beschwerdefrist, etc.).
+
+### Rule 1.8 — DE ZPO §234(1)2 Wiedereinsetzungsantrag (Begründungsfrist, 1 Monat)
+
+- **Rule code:** event-rooted, te=201, sibling to 1.7
+- **Name (DE):** Wiedereinsetzungsantrag — Begründungsfrist (§ 234 Abs. 1 S. 2 ZPO)
+- **Name (EN):** Petition for re-establishment — appeal/revision grounds period (ZPO §234(1) sentence 2)
+- **Party:** both
+- **Anchor:** `trigger_event_id = 201` (`wegfall_hindernisses_de_zpo`)
+- **Duration:** 1, months
+- **Timing:** after
+- **Priority:** optional
+- **is_court_set:** false
+- **condition_expr:** **FLAG** — needs a flag like `{"flag":"begruendungsfrist"}` or similar to distinguish from Rule 1.7 because today's data model can't differentiate "the missed deadline was a Berufungsbegründungsfrist" without an explicit flag from the caller. m to decide whether to add a flag or leave the rule as "informational alternative" rendered alongside 1.7.
+- **Legal source:** `DE.ZPO.234.1`
+- **Notes:** ZPO §234(1) Satz 2: "Die Frist beträgt einen Monat, wenn die Partei verhindert war, die Frist zur Begründung der Berufung, der Revision, der Nichtzulassungsbeschwerde oder der Rechtsbeschwerde oder die Frist des § 234 Abs. 3 einzuhalten."
+
+### Rule 1.9 — DE ZPO §234(3) — 1-Jahres-Ausschlussfrist
+
+- **Rule code:** informational sibling
+- **Name (DE):** Absolute Ausschlussfrist Wiedereinsetzung ZPO (1 Jahr)
+- **Name (EN):** Absolute cut-off for re-establishment, ZPO (1 year)
+- **Party:** both
+- **Anchor:** missed-deadline date (schema FLAG as 1.2)
+- **Duration:** 12, months
+- **Timing:** after
+- **Priority:** informational
+- **is_court_set:** false
+- **condition_expr:** NULL
+- **Legal source:** `DE.ZPO.234.3`
+- **Notes:** "Nach Ablauf eines Jahres, von dem Ende der versäumten Frist an gerechnet, kann die Wiedereinsetzung nicht mehr beantragt … werden."
+
+**Summary for `wiedereinsetzung`:** four of the five linked event categories (DE PatG, DE ZPO, EPC, DPMA) already have **existing rules** that just need `concept_id` set — see § 6. The genuinely new substance is **Rule 1.1** (UPC R.320, te 207), plus a set of informational 1-year cut-off rules (1.2/1.4/1.6/1.9), plus the optional ZPO §234(1) sentence-2 variant (1.8). Six new rules in total, one duplicate-flagged, four pure linkages. **FLAG:** UPC fee for Wiedereinsetzung (R.150(1)(p)) is not modelled as a rule — should it appear as a sibling informational rule with the fee amount? Today's model doesn't carry money, so probably no, but worth m's call.

+
+## 2. Concept: `schriftsatznachreichung` (Schriftsatznachreichung, § 296a ZPO)
+
+**Concept ID:** `b7a3cb3e-ef7e-47a1-8067-be0fe35a4235`
+**Party:** both · **Category:** submission
+**Linked event_categories:**

+- `muendl-verhandlung.gehalten` (Soeben gehalten / heute)
+- `muendl-verhandlung.geladen` (Geladen — wann findet sie statt?)
+
+**Existing rules:** te 205 (`ende_muendl_verhandlung`) already has rule `3c36f149-…` (3 weeks). Linkage only — see § 6.
+
+### Rule 2.1 — DE ZPO §296a Schriftsatznachreichungsfrist
+
+- **Rule code:** event-rooted, te=205
+- **Proceeding type:** NULL (event-rooted) — primarily DE_INF/DE_NULL/OLG/BGH context but cross-cutting via the trigger event.
+- **Name (DE):** Schriftsatznachreichung (§ 296a ZPO)
+- **Name (EN):** Subsequent written submission (ZPO §296a)
+- **Party:** both
+- **Anchor:** `trigger_event_id = 205` (`ende_muendl_verhandlung`)
+- **Duration:** 3, weeks
+- **Timing:** after
+- **Priority:** optional *(only available if court grants Schriftsatznachreichungsfrist; otherwise §296a bars new attack/defence means)*
+- **is_court_set:** **true** — the deadline date is set by the court order granting the Schriftsatznachreichungsfrist, not by the statute itself. ZPO §296a permits the court to set it; typical practice is 2-3 weeks but the court fixes the exact date.
+- **condition_expr:** NULL
+- **Legal source:** `DE.ZPO.296a`
+- **Notes:** **DUPLICATE of existing rule** — linkage only. **FLAG:** the existing rule sets `is_court_set=false` and a fixed 3-week duration. Strictly, the court sets the date, so `is_court_set=true` is more accurate; the 3-week duration is a typical-case estimate. m to decide whether to update the existing rule or leave the heuristic as-is and document the deviation.
+
+### Rule 2.2 — Schriftsatznachreichung — Beschränkung auf in der Verhandlung erörterte Punkte (informational)
+
+- **Rule code:** informational sibling
+- **Name (DE):** Beschränkung der Schriftsatznachreichung (nur Bezug auf Verhandlungspunkte)
+- **Name (EN):** Schriftsatznachreichung scope limit (only matters raised at the hearing)
+- **Party:** both
+- **Anchor:** same as 2.1
+- **Duration:** 0
+- **Timing:** after
+- **Priority:** informational
+- **is_court_set:** false
+- **condition_expr:** NULL
+- **Legal source:** `DE.ZPO.296a`
+- **Notes:** Reminds the user that a Schriftsatznachreichung is limited to matters raised at the oral hearing — new attack/defence means are barred under §296a. Useful for the cascade card; not a calendar deadline.
+
+### Rule 2.3 — Schriftsatznachreichung — UPC equivalent? (open question)
+
+**FLAG:** UPC RoP has no direct §296a analogue. Post-hearing submissions in UPC proceedings are limited and require court leave (general practice; see R.117). I am intentionally **not** drafting a UPC rule under this concept and recommend m confirm the concept stays DE-only. If the cascade exposes the concept under a UPC entry, that is a cascade taxonomy bug, not a rule gap.
+
+**Summary:** 2 substantive rules (1 duplicate-flagged, 1 informational). Concept is essentially solved by linkage + 1 informational sibling.

+## 5. Concept: `counterclaim-for-revocation` (Nichtigkeitswiderklage, UPC R.25)
+
+**Concept ID:** `52134900-2bcf-4810-9de3-0b0681c79dd7`
+**Party:** defendant · **Category:** submission
+**Linked event_category:**
+- `ich-moechte-einreichen.widerklage.nichtigkeit-upc` (Nichtigkeitswiderklage UPC R.25)
+
+**Existing rules:** UPC R.25 / RoP 25-32 are **already encoded** in `UPC_INF` (proceeding_type_id=8) as flag-gated rules using `condition_expr.flag = "with_ccr"`:
+
+| Rule code | Name | Duration | condition_expr | concept_slug today |
+|---|---|---|---|---|
+| `inf.def_to_ccr` | Erwiderung auf Nichtigkeitswiderklage | 2 months | `{"flag":"with_ccr"}` | `defence-to-counterclaim-for-revocation` |
+| `inf.reply` (with_ccr variant) | Replik | 2 months | `{"flag":"with_ccr"}` | `reply-to-defence` |
+| `inf.reply_def_ccr` | Replik auf Erwiderung zur Nichtigkeitswiderklage | 2 months | `{"flag":"with_ccr"}` | (not yet checked) |
+| `inf.rejoin` (with_ccr) | Duplik | 1 month | `{"flag":"with_ccr"}` | `rejoinder` |
+| `inf.rejoin_reply_ccr` | Duplik auf Replik | 1 month | `{"flag":"with_ccr"}` | (not yet checked) |
+| `inf.def_to_amend` | Erwiderung auf Patentänderungsantrag | 2 months | `{"op":"and","args":[{"flag":"with_ccr"},{"flag":"with_amend"}]}` | `defence-to-application-to-amend` |
+| `inf.app_to_amend` | Antrag auf Patentänderung | 2 months | `{"op":"and","args":[{"flag":"with_ccr"},{"flag":"with_amend"}]}` | **NULL** (orphan column) |
+| `inf.reply_def_amd` | Replik auf Erwiderung zum Patentänderungsantrag | 1 month | same | `reply-to-defence-to-application-to-amend` (or similar) |
+| `inf.rejoin_amd` | Duplik auf Replik zum Patentänderungsantrag | 1 month | same | `rejoinder-on-amend` (or similar) |
+
+**The CCR itself** — the act of filing the Nichtigkeitswiderklage — is part of `inf.sod` (Statement of Defence) when `with_ccr=true`. The 3-month SoD period from R.23 doubles as the CCR-filing period from R.25.
+
+### Proposal 5.1 — Do **not** seed new rules under this concept.
+
+The concept models a logical artifact ("Nichtigkeitswiderklage") that is, in the data model, an attribute of the SoD rather than a separate timed event. Seeding new rules under `counterclaim-for-revocation.concept_id` would either:
+
+- (a) Duplicate the existing `inf.sod` / `inf.def_to_ccr` / etc. rules — wasteful, fragile (two sources of truth for the same legal period).
+- (b) Add a synthetic "filing CCR" rule with the same 3-month period as `inf.sod` — redundant once `inf.sod`'s `concept_id` is set correctly.
+
+### Proposal 5.2 — Link existing UPC_INF rules to this concept (linkage only).
+
+Specifically:
+
+| Rule | Current `concept_id` link | Proposed action |
+|---|---|---|
+| `inf.sod` (UPC_INF) | `statement-of-defence` (presumably) | Leave as-is — SoD's primary concept is "Statement of Defence". |
+| `inf.app_to_amend` (UPC_INF, with_ccr+with_amend) | NULL | **Link to `counterclaim-for-revocation`** — this is the genuine "CCR-derived deadline" that has no concept today. |
+
+**FLAG:** Whether the cascade entry `ich-moechte-einreichen.widerklage.nichtigkeit-upc` should resolve to the SoD itself or to a CCR-card-with-derivative-deadlines is a UX question m needs to decide. My read: when a user clicks "I want to file Nichtigkeitswiderklage", they want to see the SoD deadline (because that's when the CCR is due — same period as SoD) plus the consequential deadlines (Defence to CCR, Replik, Duplik, Patent amendment etc.). A cleaner data-model fix is to add a junction `paliad.concept_rules` (many-to-many) so a rule can belong to multiple concepts (e.g. `inf.sod` ∈ {`statement-of-defence`, `counterclaim-for-revocation`}). That's a Phase 3+ schema add and outside Slice 12's scope.
+
+### Proposal 5.3 — Alternative: event-rooted CCR rule.
+
+Trigger event 1 (`statement_of_defence_which_includes_a_counterclaim_for_revocation`) exists but lacks `concept_id` text. Setting `paliad.trigger_events.concept_id = 'counterclaim-for-revocation'` on te 1 and seeding 1-3 event-rooted rules that fire from te 1 (Defence to CCR within 2 months, Reply within 2 months, etc.) would give the cascade card concrete deadlines without duplicating the SoD-tree rules. This is the pattern the audit § 3.4 description hints at.
+
+**Recommendation:** Proposal 5.2 + 5.3 combined. m to confirm. Until decided, I'm **not** drafting fresh rules for this concept — it's a data-model question disguised as a coverage gap.
+
+---
+
+## 6. Track A — Linkage-only UPDATEs (no legal review needed)
+
+The following `paliad.deadline_rules` rows already exist; they only need `concept_id` pointed at the right concept. These are the lowest-risk part of Slice 12 and can be applied via the admin UI as no-op edits (or as a one-off migration if m prefers).
+
+```sql

+```
+
+After these 7 rows update, `counterclaim-for-revocation` is the only remaining concept with `direct rule_count = 0`, and that is by design (see § 5).
+
+---
+
+## 7. Track B — Genuinely new rule drafts
+
+Pure-new (not in DB today), to be added through `/admin/rules`:
+
+| # | Concept | Rule | Status |
+|---|---|---|---|
+| 1.1 | `wiedereinsetzung` | UPC R.320 Wiedereinsetzungsantrag (te 207) | NEW |
+| 1.2 | `wiedereinsetzung` | UPC R.320 1-Jahres-Ausschlussfrist | NEW, schema FLAG |
+| 1.4 | `wiedereinsetzung` | EPC R.136 1-Jahres-Ausschlussfrist | NEW, schema FLAG |
+| 1.6 | `wiedereinsetzung` | DE PatG §123 1-Jahres-Ausschlussfrist | NEW, schema FLAG |
+| 1.8 | `wiedereinsetzung` | DE ZPO §234(1)2 — 1-Monat Begründungsfrist | NEW, condition_expr FLAG |
+| 1.9 | `wiedereinsetzung` | DE ZPO §234(3) 1-Jahres-Ausschlussfrist | NEW, schema FLAG |
+| 2.2 | `schriftsatznachreichung` | §296a-Beschränkung (informational) | NEW |
+| 3.2 | `versaeumnisurteil-einspruch` | ZPO §339(2) Auslandszustellung 1 Monat | NEW, condition_expr FLAG |
+| 3.3 | `versaeumnisurteil-einspruch` | ZPO §340 Inhalt der Einspruchsschrift (info) | NEW |
+| 3.4 | `versaeumnisurteil-einspruch` | ZPO §342 Rechtsfolge (info) | NEW |
+| 4.2 | `weiterbehandlung` | R.135(2) Ausschlüsse (info) | NEW |
+| 4.3 | `weiterbehandlung` | Weiterbehandlungsgebühr (info) | NEW |
+| 5.x | `counterclaim-for-revocation` | (none — see § 5 proposal) | — |
+
+**Total new rule drafts: 12.** That is well under the "50 rule drafts" estimate in the task brief, because the linkage path covers the bulk of what looked like missing coverage. **FLAG:** if m wants me to draft additional UPC R.320 jurisdiction-specific variants (UPC_REV, UPC_PI, UPC_APP, UPC_DAMAGES, UPC_DISCOVERY) as separate proceeding-rooted rules instead of one shared event-rooted rule (Rule 1.1), that adds ~6-7 more drafts.
+
+---
+
+## 8. Open questions / FLAGs index
+
+For convenience, all `**FLAG**`-marked items in one place. m's decision is needed on each before /admin/rules ingest of the corresponding rule.
+
+| ID | Section | Question |
+|---|---|---|
+| F1 | § 0 | Count discrepancy: 9 vs 5 — confirm the other 4 audit-named orphans were intentionally resolved, not lost. |
+| F2 | § 0 | Redefine the orphan KPI to also count `trigger_event_id → trigger_events.concept_id`, so the count reflects actual UX coverage. |
+| F3 | § 1.1 | UPC R.320: one event-rooted rule (te 207) vs seven proceeding-rooted clones (UPC_INF/UPC_REV/UPC_PI/UPC_APP/UPC_DAMAGES/UPC_DISCOVERY/UPC_APP_ORDERS). |
+| F4 | § 1.2, 1.4, 1.6, 1.9 | 1-year cut-off rules have no clean anchor in the current schema; informational rendering vs new `frist_versaeumt_*` trigger event. |
+| F5 | § 1.4 | EPC R.136(1) third sentence: priority-restoration 2-month cut-off — separate rule? |
+| F6 | § 1.8 | ZPO §234(1) sentence 2 (Begründungsfrist) — flag-gated or informational sibling? |
+| F7 | § 1.x | UPC Wiedereinsetzungs-Gebühr (R.150(1)(p)) — surface as informational rule or out of scope? |
+| F8 | § 2.1 | Schriftsatznachreichung existing rule has `is_court_set=false`; strictly it's court-set. Update the row or leave the heuristic in place? |
+| F9 | § 2.3 | Confirm `schriftsatznachreichung` is DE-only — cascade should not expose it under UPC entries. |
+| F10 | § 3.2 | ZPO §339(2) Auslandszustellung — flag name for `condition_expr` (e.g. `auslandszustellung`). |
+| F11 | § 5 | `counterclaim-for-revocation` — link existing UPC_INF rules (proposal 5.2) vs event-rooted CCR rule under te 1 (proposal 5.3) vs both. |
+| F12 | § 5 | Many-to-many concept↔rule junction (`paliad.concept_rules`) as a Phase 3+ schema add. |

+## 10. What's next (if m approves)
+
+1. **Track A first** (low risk): apply the 7 linkage UPDATEs from § 6 via `/admin/rules` PATCH. Cascade UX immediately recovers for 4 of 5 concepts.
+2. **Track B legal-review pass:** m or HLC lawyer signs off on the 12 new drafts in § 7 — adjust durations / phrasings as needed.
+3. **Ingest Track B** via `/admin/rules` POST, one rule at a time. Each new rule goes into `lifecycle_state='draft'` first; m promotes to `published` after spot-checking via the calculator preview endpoint (Slice 11a).
+4. **Schema follow-ups** (FLAGs F2, F4, F12) deferred to Phase 3 follow-up tickets — not in Slice 12 scope.
+
+**Estimated rule count after Slice 12 land:** Track A linkage = 7 connections, Track B new rules = 12 drafts → total `paliad.deadline_rules` row count grows from 249 to **261**; orphan-concept count drops from 5 to **1** (only `counterclaim-for-revocation`, which is by design — see § 5).

+# 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.

+-- can't reference other tables, so a trigger is the only way to
+-- evaluate the (proceeding_types.category = 'fristenrechner')
+-- predicate per row.
+--
+-- Why trigger over deferrable-FK-to-partial-index: a partial unique

+-- the existing schema reference in mig 027. A trigger keeps the FK
+-- in place and just adds the category predicate on top.
+--
+-- Behaviour:
+--   - INSERT/UPDATE with proceeding_type_id IS NULL: pass (NULL is allowed).
+--   - INSERT/UPDATE with proceeding_type_id pointing at a
+--     fristenrechner-category row: pass.

+--     its staging row too. (Deadlines are normally archived, not

+--   - reason is a free-text discriminator: 'no_match' | 'ambiguous'
+--     today; the editor in Slice 11 may add 'manual_unbound' or
+--     similar in the future.

+-- projection" affordance on legacy data (1 of 26 deadlines currently

+--
+-- Matching strategies (in priority order; first unique hit wins):
+--
+--   1. rule_code-prefix extraction from title. Titles like
+--      "RoP.023 — Klageerwiderung" carry the rule citation in the
+--      prefix; we extract the leading citation token and JOIN on
+--      deadline_rules.rule_code = extracted. When the rule_code
+--      resolves to multiple rules (e.g. RoP.023 → 2 rules — DE
+--      Klageerwiderung + EN Statement of Defence), the remaining
+--      title fragment narrows by name ILIKE.
+--
+--   2. exact title match against rule.name OR rule.name_en (LOWER).
+--      Mostly hits common Pipeline-A names ("Antrag auf
+--      Schadensbemessung" → 1 unique rule); ambiguous for shared
+--      names like "Klageerwiderung" (8 rules across proceedings).
+--
+--   3. deadline_concepts.aliases match. Each concept carries a
+--      text[] of canonical aliases; if LOWER(d.title) is in the
+--      aliases array, we pick the rules with that concept_id. Today
+--      the alias coverage is thin (no aliases for "Schutzschrift"
+--      etc.), but the strategy is shaped so a future seed lights
+--      it up.
+--
+-- For each deadline, we collect all candidates across the three
+-- strategies, dedupe by rule.id, and:
+--   - exactly 1 candidate → UPDATE rule_id (matched).
+--   - 0 candidates → orphan with reason='no_match'.
+--   - ≥2 candidates → orphan with reason='ambiguous', candidate_rule_ids
+--     populated so a legal-review pass can hand-pick.
+--
+-- Per-project narrowing by proceeding_type_id is the design's primary
+-- discriminator. In the live corpus today all 11 projects have
+-- proceeding_type_id IS NULL (Slice 5 retired litigation codes from
+-- project-binding; the fristenrechner-side rebinding hasn't happened),
+-- so this slice can't use proceeding-narrowing on production data.
+-- The CTE still includes the predicate so the migration self-tunes
+-- the moment proceeding_type_id starts getting populated.
+--
+-- Defensive backup: paliad.deadlines is snapshotted to
+-- paliad.deadlines_pre_089 before the UPDATE so an operator can
+-- restore individual rule_id values if a hand-link goes wrong post
+-- mig. The table is dropped in the down-migration; Slice 11 (rule
+-- editor) can drop it once orphan resolution finishes in prod.

+-- unique constraint on deadline_id alone — a deadline may legitimately
+-- get re-orphaned after a resolution rollback; but re-running 090 on
+-- the same corpus must not duplicate orphan rows for unresolved
+-- deadlines).
+--
+-- Hard assertion at end: SUM(matched) + SUM(orphans for current

+--      EXISTS — idempotent re-run). The snapshots persist after the
+--      drop as audit anchors; the down migration restores from them.
+--   2. ADD COLUMN rule_codes text[] to paliad.deadline_rules and
+--      backfill from paliad.event_deadline_rule_codes. Pipeline-C
+--      deadlines carry multi-code rules (e.g. R.198 / R.213 carry
+--      [RoP.029.a, RoP.030]) which don't fit deadline_rules.rule_code
+--      (singular text); mig 085 left rule_code NULL on the 77
+--      Pipeline-C rows. Without this backfill the drop would silently
+--      lose 72 RoP citations.
+--   3. Hard assertion: every event_deadline_rule_codes row resolves to
+--      a deadline_rules row via the sequence_order = 1000 +
+--      event_deadlines.id convention from mig 085. If any row didn't
+--      land, fail loudly before dropping the source.

+-- t-paliad-200 / Fristen Phase 3 Slice 9 follow-up B — retire the
+-- 'litigation' category from the rule corpus.
+--
+-- Lorenz's Slice 9 (t-paliad-195) deferred this drop because 40 active
+-- paliad.deadline_rules still pointed at the 7 litigation-category
+-- proceeding_types (INF, REV, CCR, APM, APP, AMD, ZPO_CIVIL). Phase 3
+-- Slice 5 retired litigation codes from project-binding (mig 087/088);
+-- this migration retires them from the rule corpus.
+--
+-- Plan choice (audit-gated, paliadin-approved): archive-all-40 rather
+-- than the original re-parent plan. The audit found:
+--
+--   * 23 of 40 Pipeline-A litigation rules share their `code` with an
+--     existing fristenrechner rule on the proposed re-parent target
+--     (e.g. `inf.oral` exists on both INF and UPC_INF). Re-parenting
+--     would leave two rules with identical (proceeding_type_id, code),
+--     breaking the implicit per-proceeding rule_code identity contract
+--     keyed off by projection / search / rule_editor.
+--   * The fristenrechner-category rules are the production version:
+--     proper German names, legal_source pinned (UPC.RoP citations),
+--     full bilateral chains, intra-proceeding counterclaim handling
+--     via inf.def_to_ccr / rev.cc_inf / etc. The Pipeline-A rules are
+--     stubs: English-only, mostly NULL legal_source, duration_value=0
+--     for 28 of 40, no spawn_proceeding_type_id wiring.
+--   * 1 live deadline ("Lecker Frist", status=completed) points at
+--     Pipeline-A inf.rejoin/INF via paliad.deadlines.rule_id. Archive-
+--     not-delete preserves the FK.
+--   * 30 intra-litigation parent_id chains would be silently broken by
+--     piecemeal re-parenting. Archive-all preserves them.
+--   * FK on deadline_rules.proceeding_type_id is ON DELETE CASCADE →
+--     proceeding_types(id). A naive DELETE of the 7 litigation rows
+--     would cascade-delete all 40 rules AND break the live deadline's
+--     rule_id FK. Rules must be moved off the litigation pt ids before
+--     the litigation rows are dropped.
+--
+-- Surfaced for legal review at merge (commit body lists these so they
+-- don't get lost as the four open coverage questions Phase 3 leaves
+-- behind):
+--
+--   1. inf.prelim (Preliminary Objection, RoP 19, 1 month) — not
+--      present on UPC_INF. Possible coverage gap for the fristenrechner
+--      ruleset; legal review to decide whether to add it.
+--   2. inf.appeal / rev.appeal / ccr.appeal as cross-proceeding spawns
+--      into UPC_APP (2 months, UPC.RoP.220.1) — fristenrechner UPC_APP
+--      currently starts standalone with no spawn from UPC_INF/UPC_REV.
+--      Possible UX gap; the Pipeline-A versions had
+--      spawn_proceeding_type_id=NULL so they weren't functional
+--      spawns either.
+--   3. ccr.amend / rev.amend (spawn rules) — superseded by
+--      inf.app_to_amend / rev.app_to_amend on UPC_INF / UPC_REV. Safe
+--      to drop.
+--   4. zpo.klage / zpo.vertanz / zpo.klageerw / zpo.berufung — no UPC
+--      analogue; redundant with DE_INF / DE_INF_OLG / DE_INF_BGH and
+--      DE_NULL / DE_NULL_BGH. Safe to drop.
+--
+-- Sequencing — every step required for the drop to be safe:
+--
+--   1. Snapshot paliad.proceeding_types and the 40 affected
+--      paliad.deadline_rules into _pre_093 audit tables.
+--   2. Create a holding proceeding_type `_archived_litigation`
+--      (category='archived', is_active=false, jurisdiction='UPC') to
+--      home the archived rules and preserve their intra-set parent_id
+--      chains across the drop.
+--   3. UPDATE all 40 rules: proceeding_type_id = archived_id,
+--      lifecycle_state='archived', is_active=false. The mig 079
+--      trigger captures every row in paliad.deadline_rule_audit.
+--   4. DELETE the 7 litigation rows from paliad.proceeding_types
+--      (now safe — nothing references them).
+--   5. Hard assertions: zero rules on litigation ids, zero litigation
+--      rows surviving, exactly 40 rules on the archive id.
+--
+-- Idempotent: re-applying is a no-op (snapshots use CREATE TABLE IF
+-- NOT EXISTS; the archive pt INSERT uses ON CONFLICT DO NOTHING; the
+-- UPDATEs are guarded by lifecycle_state='archived' so they only fire
+-- once; the DELETE targets category='litigation' which becomes empty
+-- after first run).
+--
+-- audit_reason wrapper at top — the mig 079 trigger on
+-- paliad.deadline_rules logs every row-level edit. The UPDATE on all
+-- 40 rules fires through that trigger, so the reason persists in

+-- Mig 093 (commit 40e49e8) retired the Pipeline-A litigation rule
+-- corpus and surfaced four open coverage questions for legal review.
+-- curie's proposal verified those questions and m signed off on:
+--
+--   * 4 new rules — preliminary-objection (RoP 19.1) on UPC_INF and
+--     UPC_REV, and merits-appeal spawn (RoP 220.1(a)) on the same two
+--     proceedings.
+--   * 4 polish PATCHes on the German civil-procedure rules — backfill
+--     legal_source on de_inf.klage, flip de_inf.erwidg to court-set
+--     with a §276 Abs.1 S.2 note, plus a defensive verify on
+--     de_inf.berufung.legal_source.
+--
+-- Final shape per the proposal § 0.3:

+--     inf.prelim         UPC_INF  parent=inf.soc      1mo  RoP.019.1   flag=with_po       optional

+-- appeal-window row once inf.decision / rev.decision is anchored
+-- (m's F2.3 decision: "appeal is always a possibility"). Visibility
+-- filtering for non-appealing projects is a frontend concern, not a
+-- rule-level flag (see proposal § 0.3 follow-up note).
+--
+-- The spawn_proceeding_type_id FK points at UPC_APP (id=11). t-paliad-204
+-- may rename the `code` string for that row but the integer id is stable;
+-- if id=11 ever moves, this migration's spawn rules still chain to the
+-- correct row.
+--
+-- Idempotency:
+--   * Backup snapshot `deadline_rules_pre_095` is CREATE TABLE IF NOT
+--     EXISTS, capturing the 4 patched rows at first run.
+--   * INSERTs use `WHERE NOT EXISTS` keyed on (proceeding_type_id, code,
+--     lifecycle_state='published') — there is no unique index on
+--     (proceeding_type_id, code) in paliad.deadline_rules (mig 093 left
+--     archived and published rows co-existing with identical codes), so
+--     ON CONFLICT is not available; WHERE NOT EXISTS is the equivalent
+--     idempotency guard.

+--     has the old value (legal_source IS NULL, is_court_set = false).

+-- 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.
