mAi: #108 - t-paliad-276 submission generator language selector (DE/EN)

Per-draft `language` column drives the .docx output language for the
submission generator. The lawyer picks DE or EN on the draft editor's
sidebar; the generator selects the language-matched template variant
(falling back through {code}.{lang} → {code} → _skeleton.{lang} →
_skeleton → letterhead) and resolves language-aware variables
({{procedural_event.name}} → name_de vs name_en).

Schema (mig 130 — bumped from 129 to deconflict with atlas's #96):
- paliad.submission_drafts.language text NOT NULL DEFAULT 'de'
  CHECK IN ('de','en'). Existing rows inherit 'de' via the default,
  preserving every legacy draft's behaviour byte-for-byte.

Backend (Go):
- SubmissionVarsContext.Lang overrides the user's UI lang. Build()
  uses it when set; falls back to user.Lang otherwise — Slice 1's
  format-only /generate path keeps working unchanged.
- SubmissionDraftService.BuildRenderBag now threads draft.Language
  through. Create/EnsureLatest seed from the UI lang (DE default).
- DraftPatch.Language landed; Update validates and rejects values
  outside {de,en}. Project-scoped + global PATCH endpoints both
  surface the field.
- resolveSubmissionTemplate(ctx, code, lang) replaces the lang-less
  predecessor. Returns the matched tier (per_code_lang / per_code /
  skeleton_lang / skeleton / letterhead) so the editor knows whether
  to surface the "Fallback: universelles Skelett" notice.
- fileRegistry registers the EN skeleton sibling (`_skeleton.en.docx`)
  alongside the DE one; per-code EN variants land in a parallel
  submissionTemplateENRegistry (empty for now — EN templates land per
  HLC authoring). 404s from Gitea fall through silently.
- /api/projects/{id}/submissions/{code}/generate accepts
  `?language=de|en` query override (one-shot path, no draft row to
  pull the column from); defaults to the user's UI lang.

Frontend (TS/JSX):
- DE/EN radio above the variables list in the draft editor sidebar.
  Switching the radio PATCHes `language` and the server returns the
  freshly-resolved bag + preview HTML so the lawyer sees EN values
  immediately.
- Fallback notice ("Fallback: universelles Skelett (keine
  sprachspezifische Vorlage)") shows when the resolved tier doesn't
  match the requested language.
- 4 new i18n keys (DE + EN) + CSS for the toggle.

Tests:
- normalizeDraftLanguage covers DE/EN/case/whitespace/unknown.
- addRuleVars language-pick test pins procedural_event.name and the
  rule.name alias to the language-matched value.
- languageFallback truth table covers all 10 (lang × tier) combos.

Build hygiene: go build/vet/test clean; bun run build clean.

+# Design: /inbox overhaul — project-events feed + filtering + list/cards/calendar toggles
+
+**Task:** t-paliad-249
+**Gitea:** m/paliad#80
+**Author:** icarus (inventor)
+**Date:** 2026-05-25
+**Status:** LOCKED — head confirmed Q1=A with two refinements (2026-05-25), see §12.
+**Branch:** `mai/icarus/inventor-inbox-overhaul`
+
+---
+
+## 0. TL;DR
+
+`/inbox` today is approval-requests only. m wants it to become the actual
+"what's new on my projects" surface — approval requests **plus** recent
+project_events on visible projects — with the same view-toggle paradigm
+as `/events` (list / cards / calendar) and a meaningful filter row.
+
+The good news: the substrate already exists.
+
+- `view_service.RunSpec` unions four sources (deadline, appointment,
+  **project_event**, **approval_request**) into one ranked `[]ViewRow`.
+- `FilterSpec` has predicates for every axis we need
+  (`ProjectEventPredicates.EventTypes`, `ApprovalRequestPredicates`).
+- `filter-bar` knows the axes we need: `time`, `project`,
+  `approval_viewer_role`, `approval_status`, `approval_entity_type`,
+  `project_event_kind`, plus `shape` / `sort` / `density`.
+- Shape renderers exist: `shape-list` (table + compact + approval), `shape-cards`
+  (day-grouped), `shape-calendar` (thin adapter on `mountCalendar`).
+
+So the work is **mostly re-mix**:
+
+1. Extend `InboxSystemView` from `Sources=[ApprovalRequest]` to
+   `Sources=[ApprovalRequest, ProjectEvent]`, default
+   `Time.Horizon=Past30d`, and add a curated `project_event.event_types`
+   default that filters out noise (approvals duplicate-suppression,
+   checklist mutations, status churn).
+2. Extend `shape-list.ts` so `row_action="approve"` no longer assumes
+   every row is an approval — rename it `"inbox"`, dispatch per
+   `row.kind` (approval → existing approve-card layout; project_event →
+   navigate-style stream row).
+3. Wire the existing view-axis selector (the chip cluster on `/events`)
+   onto `/inbox`'s host, persisting selection via the filter-bar URL
+   codec (axis `shape` already in `AxisKey`).
+4. Add a high-watermark read cursor (`paliad.users.inbox_seen_at`) +
+   `POST /api/inbox/mark-all-seen` + extend `/api/inbox/count` to count
+   unseen project_events too. Adds one new axis `unread_only` to the bar.
+
+That's Slice A. Slice B layers cards + calendar toggles cleanly. Slice C
+is per-item dismissal — keep out of v1 unless the cursor proves not
+enough (m's pick Q3 is the cursor).
+
+No new aggregation service, no new endpoint family — the inbox runs on
+`/api/views/inbox/run` like every other system view does today.
+
+---
+
+## 1. Current `/inbox` state
+
+**Routes (`internal/handlers/approvals.go`):**
+
+| Path                                  | Behaviour                                                    |
+|---------------------------------------|--------------------------------------------------------------|
+| `GET /inbox`                          | Serves `dist/inbox.html`, a thin shell. No SSR data.         |
+| `GET /api/inbox/pending-mine`         | Approval requests I can approve.                              |
+| `GET /api/inbox/mine`                 | Approval requests I submitted (all statuses by default).      |
+| `GET /api/inbox/count`                | `{count: N}` for the sidebar bell badge — `PendingCountForUser`. |
+| `GET /api/approval-requests/{id}`     | Hydrate one request (used by suggest-changes modal).          |
+| `POST /api/approval-requests/{id}/{action}` | `approve` / `reject` / `revoke` / `suggest-changes`.    |
+
+**Data path:** `frontend/src/client/inbox.ts` mounts the universal
+`FilterBar` over the inbox `SystemView` (slug `"inbox"`, sources
+`[approval_request]`, viewer_role `any_visible`, status `[pending]`).
+The bar fetches `/api/views/system`, hands the spec to itself, calls
+`/api/views/inbox/run?…`, and stamps rows via `shape-list.ts`'s
+`renderApprovalList(rows)` path (gated by `row_action="approve"`).
+
+**Action wiring:** `wireApprovalActions(host)` listens on
+`.views-approval-action` clicks; on success it triggers
+`bar.refresh()` and `refreshInboxBadge()` (which pokes
+`/api/inbox/count`).
+
+**Empty state + admin nudge:** when the result list is empty AND the
+caller is `global_admin` AND no `approval_policies` row exists firm-wide,
+the page shows a "configure policies" CTA. Otherwise the localized
+"no items" empty-state text.
+
+**Sidebar bell:** `Sidebar.tsx:143` `navItem("/inbox", BELL_ICON, …)`
+plus `client/sidebar.ts:320–345`'s `initInboxBadge` which polls
+`/api/inbox/count` every 60s. Badge clamps to `"9+"`.
+
+### What aggregates cleanly
+
+The whole approval flow already plugs into `RunSpec`'s union pipeline.
+That's the win — extending sources from `[ApprovalRequest]` to
+`[ApprovalRequest, ProjectEvent]` is a `[]DataSource` literal edit in
+`InboxSystemView()` and the engine fans out per source, sorts, returns
+one `[]ViewRow`. The hard work (`runProjectEvents` + the
+visibility predicate + project metadata join) is already in
+`view_service.go:344–430`.
+
+### What doesn't aggregate (yet)
+
+- **Read state.** There is no `inbox_seen_at` on `paliad.users` (verified
+  via information_schema). The bell badge counts pending **approval
+  requests for the caller** only — it has no notion of "new project
+  events since last visit". We have to add it.
+- **Mixed `row_action`.** `shape-list.ts`'s `renderApprovalList` assumes
+  every row is an approval and unconditionally parses
+  `row.detail` as an `ApprovalDetail`. Project_event rows in the same
+  list would crash the parse. We need to branch per `row.kind` inside
+  the inbox row stamper.
+- **`/inbox` shape toggle.** `client/inbox.ts` hardcodes `shape-list`;
+  the `shape` axis is wired into `filter-bar/axes.ts` but `/inbox`'s
+  `INBOX_AXES` deliberately omits it (because today the only meaningful
+  shape was list). Adding it onto INBOX_AXES + a small dispatcher in
+  `onResult` gives us cards + calendar for free.
+
+Everything else (sidebar entry, /api/views machinery, FilterBar URL
+codec, RowAction validation) carries through unchanged.
+
+---
+
+## 2. Event-type catalogue for inbox v1 (Q1)
+
+This is the only design pick that requires a head/m signal. **Open
+question Q1 in §9 — defaulting to (A) until head answers.**
+
+### (R) Recommendation (A): curated subset
+
+Sources: `[approval_request, project_event]`.
+
+**Approval requests:** all rows whose `viewer_role=any_visible` AND
+status ∈ {pending} by default; the existing chip cluster
+(approver_eligible / self_requested / any_visible) stays. Decided
+requests are filtered by the chip, not hidden by source-removal — so a
+user who wants to see "what got approved this week" toggles the status
+chip rather than the source.
+
+**Project events:** filter by `event_type ∈ InboxProjectEventKinds`
+where InboxProjectEventKinds is a new sub-list of KnownProjectEventKinds:
+
+| event_type              | In inbox v1? | Reason                                                              |
+|-------------------------|--------------|---------------------------------------------------------------------|
+| `project_created`       | no           | The author already saw the page; not news to the team yet (the team grows post-creation). |
+| `project_archived`      | **yes**      | High-signal lifecycle event ("Akte XY wurde archiviert").           |
+| `project_reparented`    | **yes**      | Hierarchy moves matter to everyone with access.                     |
+| `project_type_changed`  | **yes**      | Same reason.                                                        |
+| `status_changed`        | no           | Currently too granular; surface in Verlauf, revisit if m disagrees. |
+| `deadline_created`      | **yes**      | New deadline on a project I can see — exactly the kind of event m named ("we should also display new events"). |
+| `deadline_completed`    | **yes**      | Likewise.                                                           |
+| `deadline_reopened`     | **yes**      | Likewise.                                                           |
+| `deadline_updated`      | **yes**      | Currently in DB (11 rows live) but not in KnownProjectEventKinds — add it. |
+| `deadline_deleted`      | **yes**      | Likewise — add to KnownProjectEventKinds.                           |
+| `deadlines_imported`    | **yes**      | Bulk-import event surfaces what got added.                          |
+| `appointment_created`   | **yes**      |                                                                     |
+| `appointment_updated`   | **yes**      |                                                                     |
+| `appointment_deleted`   | **yes**      |                                                                     |
+| `note_created`          | **yes**      | A note is "someone said something about this project". High-signal; add to KnownProjectEventKinds. |
+| `our_side_changed`      | **yes**      | Party-side flip; high-signal, add to KnownProjectEventKinds.        |
+| `member_role_changed`   | no           | Admin churn; would dominate active users' inbox. Revisit slice B. |
+| `*_approval_requested`  | **no — de-duped** | The approval_request row itself carries the signal; the audit event is the same fact in a different table. Filtering it out avoids duplicate inbox entries. |
+| `*_approval_approved/rejected/revoked` | **no — de-duped** | Same reason. The approval_request row's status flip is what the user sees. |
+| `*_approval_changes_suggested` | **no — de-duped** | Same. |
+| `approval_decided`      | no           | This is the umbrella audit-only kind; superseded by the approval_request row. |
+| `checklist_*`           | no           | Low signal; checklists are surfaced on the project's checklist page. |
+
+The de-dup pattern means: if a row exists in `approval_requests` for an
+entity, the corresponding `*_approval_*` project_event is **not** shown
+in the inbox — we trust the approval_request row.
+
+### Alternative (B): everything in KnownProjectEventKinds + approvals
+
+Simpler — no curated sub-list, no de-dup. Two drawbacks:
+
+1. `*_approval_*` duplicates would render twice per request.
+2. `status_changed` and `member_role_changed` are admin churn; in firm
+   tests both would dominate.
+
+If head picks B, we need at minimum the `*_approval_*` de-dup; otherwise
+the inbox renders the same fact twice.
+
+### Alternative (C): minimal — approvals + appointment_* + deadline_*
+
+Tightest set. Drops notes + our_side_changed + project_*. Risk: m's
+brief literally says "new events that relate to one's projects" — notes
+and side changes ARE such events. C feels too narrow.
+
+---
+
+## 3. Read/unread model (Q3 → R: high-watermark cursor)
+
+### (R) Decision: per-user high-watermark `inbox_seen_at`
+
+**Schema:**
+
+```sql
+ALTER TABLE paliad.users
+    ADD COLUMN inbox_seen_at timestamptz NULL;
+```
+
+NULL means "never visited" → everything counts as unread. The high-water
+cursor advances exactly when the user POSTs to
+`/api/inbox/mark-all-seen` (UI affordance: a button in the inbox header
++ implicit advance on page-mount, see Slice A wiring below).
+
+### Why cursor, not per-item
+
+m's recommendation: cursor. Mine matches: single column, no fan-out
+table, covers the common case ("I checked my inbox, mark everything
+read"). Per-item dismiss is Slice C — opt-in only if the cursor proves
+inadequate. The risk we're guarding against: a single high-value pending
+approval that's a week old gets buried by 80 fresh deadline_updated
+events; the user clears the badge and may now never look at the
+approval. Mitigation: **approval_requests with status=pending never
+fall behind the cursor** — they count toward the badge regardless of
+seen_at. This is a tiny conditional in the count query (Slice A).
+
+### Cursor advance behaviour
+
+- **Explicit:** "Alles als gelesen markieren" button in the inbox
+  header. POSTs `/api/inbox/mark-all-seen`; server sets
+  `inbox_seen_at = now()`.
+- **Implicit:** when the page mounts AND the bar surfaces at least one
+  row that's newer than the current cursor, the *new* cursor is
+  remembered locally as the timestamp of the **newest visible row**.
+  We do **not** auto-advance the server cursor on mount — too easy to
+  lose items behind a stray pageview. The "neu" highlight on rows
+  newer than the saved cursor is the silent UX. Explicit click is the
+  one and only path to clearing the badge.
+
+### `unread_only` axis
+
+New filter-bar axis (Slice A):
+
+```ts
+// types.ts
+unread_only?: boolean;
+```
+
+When `true`, the bar overlays a FilterSpec predicate:
+`row.event_date > inbox_seen_at` (substrate-side filter; for project_events
+that's `pe.created_at > $cursor`, for approval_requests that's
+`requested_at > $cursor` OR `status='pending'` per the carve-out above).
+
+Default: **unread_only=true** for first paint (per Slice A — landing on
+the inbox shows you what's new). The "Alle" chip flips it off so the
+user can see history.
+
+---
+
+## 4. Filter contract
+
+The bar surfaces these axes on `/inbox` (`INBOX_AXES` constant in
+`client/inbox.ts`):
+
+| Axis                     | Why on /inbox                                                        | New? |
+|--------------------------|----------------------------------------------------------------------|------|
+| `time`                   | "Last 30 days" (default) with chip cluster + "Älter anzeigen" .       | already |
+| `project`                | Single-select autocomplete from visible projects.                    | already |
+| `approval_viewer_role`   | "Zur Genehmigung" / "Eigene Anfragen" / "Alle sichtbaren".            | already |
+| `approval_status`        | pending / approved / rejected / revoked / changes_requested.         | already |
+| `approval_entity_type`   | Frist / Termin (chip pair).                                          | already |
+| `project_event_kind`     | Chip cluster over InboxProjectEventKinds.                            | already |
+| **`unread_only`**        | Boolean toggle ("Nur ungelesen" / "Alle"); defaults to ungelesen.    | **Slice A new axis** |
+| `shape`                  | list / cards / calendar.                                             | already in `AxisKey`, not yet on `/inbox` |
+| `sort`                   | Newest first (default) / oldest first.                               | already |
+| `density`                | comfortable / compact.                                               | already |
+
+**Default landing state** for a brand-new pageview:
+`?time=past_30d&unread_only=true&a_status=pending&shape=list&sort=date_desc`.
+
+Bookmarks from older clients (e.g. the legacy `?tab=pending-mine`)
+still work because `client/inbox.ts:46–58` already applies the legacy
+tab → `a_role` redirect at hydration.
+
+### Source-removal not exposed as an axis
+
+Users do **not** see a "show approvals only / show events only" chip.
+The signal we want is "what's new across my projects"; splitting the
+two via the filter row is busywork. If they want approvals-only they
+chip-pick `project_event_kind` empty + status=any (or future axis pick
+`source=approval_request`). If feedback shows otherwise after Slice A
+ships, we add the axis in Slice B trivially (`Sources` is a
+spec.Sources literal flip).
+
+---
+
+## 5. View toggle implementation plan (Q5 → R: list / cards / calendar)
+
+The pattern `/events` uses today (see `frontend/src/events.tsx:107–141`
+for the `<div className="events-view-selector">` block and
+`client/events.ts:617–650` for the `applyView` function):
+
+- One chip cluster `data-event-view="cards|list|calendar"`.
+- Active class toggle.
+- Per-shape `display: none` on the table-wrap / cards-wrap / cal-wrap
+  hosts.
+- For calendar, `mountCalendar()` constructs a month/week/day grid
+  into a dedicated `events-calendar-wrap` host; the handle is destroyed
+  on shape-leave so its URL state doesn't leak into the other shapes.
+
+### Mapping onto /inbox
+
+The cleanest path: **use `filter-bar`'s built-in `shape` axis instead of
+a per-page selector.** The axis already round-trips into the URL via
+`url-codec.ts` and serialises into `RenderSpec.Shape`. `client/inbox.ts`
+just needs:
+
+1. Add `"shape"` to `INBOX_AXES`.
+2. Dispatch in the `onResult` callback by `effective.render.shape`:
+
+   ```ts
+   onResult: (result, effective) => {
+     switch (effective.render.shape) {
+       case "cards":    return paintCards(result.rows, effective.render, ...);
+       case "calendar": return paintCalendar(result.rows, ...);
+       case "list":
+       default:         return paintList(result.rows, effective.render, ...);
+     }
+   }
+   ```
+
+3. The renderers exist already: `renderCardsShape` in
+   `views/shape-cards.ts`, `renderCalendarShape` in
+   `views/shape-calendar.ts`, `renderListShape` in `views/shape-list.ts`.
+   The only piece of new code is the per-shape host-clearing on switch
+   (so we don't leak a stale shape's DOM into the new host).
+
+### Calendar shape — items without dates
+
+Calendar can only render rows with a calendar-mappable date. Today:
+
+- **approval_request:** `requested_at` (timestamp). Maps fine, but
+  shows up as a single point — rendering an approval-request on a month
+  grid is semantically "you got asked on this day". OK for v1.
+- **project_event:** `created_at`. Same shape.
+- **deadline:** `due_date`. Already supported.
+- **appointment:** `start_at`. Already supported.
+
+So every row in the inbox v1 has a calendar position. No
+need to filter rows on calendar-mount. **One caveat:** the calendar
+shape currently doesn't render action affordances (approve/reject) — it
+opens a detail dialog on click. Slice B accepts that: clicking an
+approval row on the calendar opens the inbox-list-style detail in a
+modal (re-using the existing per-row /api/approval-requests/{id}
+fetch). Out of scope for Slice A.
+
+### Cards shape — day-grouped chronological cards
+
+`shape-cards.ts` groups by day and renders one card per row, with
+title + meta + actor. The approval-card layout there is the standard
+card (no approve buttons — same caveat as calendar). For Slice B, we
+extend `shape-cards.ts` to detect `row.kind === "approval_request"
+&& row.detail.status === "pending"` and stamp the approve/reject button
+strip inline. The DOM template is the same as
+`shape-list.ts:renderApprovalRow`, so most of the work is hoisting that
+template into a shared util.
+
+---
+
+## 6. Backend aggregation service (Q6 → R: reuse RunSpec)
+
+**Decision: do not build a new aggregation service.** The
+substrate-level work is exactly two edits:
+
+### 6.1 InboxSystemView (system_views.go:103–144)
+
+```go
+func InboxSystemView() SystemView {
+  return SystemView{
+    Slug: "inbox",
+    Name: "Inbox",
+    Filter: FilterSpec{
+      Version: SpecVersion,
+      Sources: []DataSource{

+    },
+  }
+}
+```
+
+Curated sub-list lives in `filter_spec.go` next to KnownProjectEventKinds:
+
+```go
+var InboxProjectEventKinds = []string{
+  "project_archived", "project_reparented", "project_type_changed",
+  "deadline_created", "deadline_completed", "deadline_reopened",
+  "deadline_updated", "deadline_deleted", "deadlines_imported",
+  "appointment_created", "appointment_updated", "appointment_deleted",
+  "note_created", "our_side_changed",
+}
+```
+
+(With Q1 pick A locked. If head picks B, drop the InboxProjectEventKinds
+list and remove the `EventTypes` predicate. If head picks C, narrow the
+list to deadline_* + appointment_* only.)
+
+KnownProjectEventKinds in `filter_spec.go:186` needs **additions** so
+`note_created`, `our_side_changed`, `deadline_updated`, `deadline_deleted`,
+`deadlines_imported` are valid filter values — without this the
+validator rejects the InboxSystemView spec. Migrate this list at the
+same time. (`event_categories` and similar grouping infra are already
+covered by `event_category_service.go` and won't move.)
+
+### 6.2 Approval-duplicate suppression
+
+In `view_service.runProjectEvents` (or in a tiny new predicate helper),
+skip `event_type LIKE '%_approval_%'` when source-set includes
+ApprovalRequest. This avoids the double-count described in Q1 §2.
+
+Implementation: extend `allowedProjectEventKinds` (view_service.go:649) to
+auto-drop the `*_approval_*` strings when the same RunSpec already
+fans out the approval_request source. One conditional, six lines.
+
+### 6.3 Mixed-row row_action
+
+`shape-list.ts` today: `row_action="approve"` → calls
+`renderApprovalList(rows)` which assumes every row is an approval.
+Need a new value:
+
+```go
+// render_spec.go
+const RowActionInbox ListRowAction = "inbox"
+```
+
+And register it in `KnownRowActions`.
+
+Frontend (`shape-list.ts`):
+
+```ts
+if (rowAction === "inbox") {
+  host.appendChild(renderInboxList(sorted));
+  return;
+}
+```
+
+Where `renderInboxList(rows)`:
+
+- approval_request rows → existing `renderApprovalRow(row)` template (the
+  per-row factor-out from `renderApprovalList`).
+- project_event rows → a new `renderProjectEventRow(row)` template:
+  timestamp + actor + title + project chip + optional "Öffnen" link
+  to the underlying entity (deadline / appointment / note / project
+  detail). Modelled on the Verlauf row in
+  `client/projects-detail.ts:651–700` (`.entity-event` markup).
+
+This makes the inbox stamping kind-aware. The
+existing `wireApprovalActions` continues to find buttons via class
+`.views-approval-action` and works unchanged.
+
+### 6.4 Endpoints — what's new vs reused
+
+| Path                                | Behaviour                                                | Slice |
+|-------------------------------------|----------------------------------------------------------|-------|
+| `GET /api/views/inbox/run`          | **Already exists** — fans the InboxSystemView spec.     | A reuse |
+| `GET /api/inbox/count`              | **Behaviour change:** count includes unread project_events on visible projects + pending approval_requests (the latter regardless of cursor). | A |
+| `POST /api/inbox/mark-all-seen`     | New. Sets `users.inbox_seen_at = now()` for the caller.  | A |
+| `GET /api/inbox/pending-mine`       | **Keep** — backwards-compat for clients (sidebar bell may still use it). | unchanged |
+| `GET /api/inbox/mine`               | **Keep** — used by the saved view `inbox-mine`.         | unchanged |
+
+The two `/api/inbox/{pending-mine,mine}` endpoints stay because they're
+narrower-than-RunSpec optimisations and used by the dashboard's
+`loadInboxSummary`. No reason to remove them.
+
+### 6.5 InboxSummary on the dashboard (out of scope, but flag)
+
+`DashboardData.InboxSummary` (dashboard_service.go:89) currently counts
+only pending approvals. If Slice C extends the badge count to include
+unread project_events, the dashboard widget also needs to swap
+`PendingCountForUser` for the new unified count — keep this as a small
+follow-up after Slice A ships and the cursor semantics are proven.
+
+---
+
+## 7. Slice plan
+
+### Slice A — Project-event aggregation + read cursor + list view
+
+**Goal:** /inbox shows pending approvals + curated project_events for
+visible projects in the last 30 days, with the new "Nur ungelesen"
+toggle. List view only.
+
+Tasks:
+
+1. **Migration `NNN_inbox_seen_at.up.sql`:**
+   `ALTER TABLE paliad.users ADD COLUMN inbox_seen_at timestamptz NULL;`
+2. **`filter_spec.go`:** extend `KnownProjectEventKinds` (add
+   `note_created`, `our_side_changed`, `deadline_updated`,
+   `deadline_deleted`, `deadlines_imported`). Add
+   `InboxProjectEventKinds` (curated subset, Q1=A).
+3. **`system_views.go`:** rewrite `InboxSystemView` per §6.1 with
+   both sources, `HorizonPast30d`, `SortDateDesc`,
+   `RowAction=RowActionInbox`.
+4. **`render_spec.go`:** add `RowActionInbox`, register in
+   `KnownRowActions`.
+5. **`view_service.go`:** in `runProjectEvents`, auto-drop
+   `*_approval_*` event_types when ApprovalRequest is in
+   `spec.Sources` (§6.2).
+6. **`approvals.go`:**
+   - New handler `handleInboxMarkAllSeen` →
+     `UPDATE paliad.users SET inbox_seen_at = now() WHERE id = $1`.
+   - Modify `handleInboxCount` to return
+     `pending_approvals_count + unread_project_events_count`. SQL
+     in approval_service.go: one new method
+     `UnseenInboxCountForUser(userID)` returning that union. Keep
+     `PendingCountForUser` (dashboard still uses it).
+7. **`shape-list.ts`:** factor `renderApprovalRow(row)` out of
+   `renderApprovalList`. Add `renderInboxList(rows)` that dispatches
+   per `row.kind`. Wire `row_action="inbox"` to it.
+8. **`client/inbox.ts`:**
+   - Add the `unread_only` axis to `INBOX_AXES` and wire to a FilterSpec
+     overlay (sub-spec `Time.Horizon=Past30d` AND
+     filter predicate "newer than cursor OR pending-approval").
+   - Render "Alles als gelesen markieren" button in the page header
+     (in `inbox.tsx`); on click POST `/api/inbox/mark-all-seen`,
+     refresh bar + badge.
+   - Listen for cursor update (server response) and refresh.
+9. **Sidebar badge (`client/sidebar.ts:initInboxBadge`):** unchanged code
+   path, but the new server count includes project_events. Add no client
+   changes for v1 — server returns the wider count.
+10. **i18n:** new keys —
+    - `inbox.title.feed` ("Inbox") replaces "Genehmigungen" in the page
+      header (since the page is now more than approvals).
+    - `inbox.subtitle.feed` ("Neuigkeiten zu Ihren Projekten und offene
+      Genehmigungen.").
+    - `inbox.action.mark_all_seen` ("Alles als gelesen markieren").
+    - `inbox.axis.unread_only.on/off`.
+    - `inbox.empty.feed` ("Keine Neuigkeiten in den letzten 30 Tagen.").
+    - `views.col.event_kind` (for the kind column in
+      table-density list).
+    - DE primary, EN secondary, both in `i18n.ts`.
+11. **Tests:** `system_views_test.go` covers the
+    InboxSystemView spec shape; new test for the de-dup helper in
+    view_service. `approval_service_test.go` adds tests for the new
+    `UnseenInboxCountForUser` method. New
+    `inbox_seen_at_test.go` covers the cursor migration + the POST
+    handler.
+12. **Verify** the page renders for a sample user with both event types
+    visible, "Nur ungelesen" toggles correctly, mark-all-seen clears the
+    badge, the project-events deduplicate against approval requests.
+
+### Slice B — Cards + calendar shape toggles
+
+**Goal:** `?shape=cards` and `?shape=calendar` work on /inbox; users can
+switch via the bar's shape chip. Approval rows on cards/calendar are
+*read-only* (open detail modal on click; no inline approve/reject).
+
+Tasks:
+
+1. **`client/inbox.ts`:** add `"shape"` to `INBOX_AXES`. Add the
+   per-shape host divs to `inbox.tsx` (one for cards, one for calendar)
+   matching the `/events` pattern. Implement `onResult` dispatch.
+2. **`shape-cards.ts`:** when `row.kind==="approval_request"` AND
+   `row.detail.status==="pending"`, stamp the approval row template
+   inline. Hoist the template out of `shape-list.ts` if reuse pays.
+3. **`shape-calendar.ts`:** approval_request rows render as date-point
+   chips; click opens a detail modal. The modal reuses the existing
+   `approval-edit-modal` for suggest-changes when the user is the
+   approver; otherwise a read-only summary.
+4. **CSS:** ensure `.entity-event` and `.views-approval-row` markup
+   coexist on the cards view without z-index clashes; lightweight
+   targeting via `.views-cards-list[data-surface="inbox"]`.
+5. **Tests:** shape toggle persistence via URL codec (already covered
+   in `url-codec.test.ts`; add one inbox-surface case).
+
+### Slice C — Badge upgrade + per-item dismiss (deferred)
+
+**Goal:** sidebar badge reflects unified count; per-item dismiss for
+power-users.
+
+Tasks:
+
+1. **`paliad.inbox_dismissals` table** —
+   `(user_id, source, row_id, dismissed_at)` PK `(user_id, source, row_id)`.
+   "source" is `approval_request` / `project_event`; "row_id" is the
+   row's UUID. New endpoint `POST /api/inbox/dismiss` body
+   `{source, row_id}`. RunSpec for inbox subtracts dismissed rows.
+2. **`/api/inbox/count`:** subtract dismissed rows from the count.
+3. **Dashboard widget:** `DashboardData.InboxSummary` swaps to a new
+   `UnifiedInboxSummary` that mirrors the page count. Backwards-compat
+   JSON: keep old fields, add `total_count` and `top_unified`.
+4. **Empty-state:** "Alle Einträge gelesen — gut gemacht."
+5. **Optional `member_role_changed` etc.:** if Slice A surfaces that
+   one of the excluded event_types is actually wanted, this slice opens
+   up `InboxProjectEventKinds` accordingly.
+
+### Why Slice A alone is shippable
+
+Slice A delivers m's full ask except the cards/calendar views — which
+are aesthetic shape toggles, not data changes. Slice A gives:
+
+- Inbox feed across approvals + project_events for visible projects
+- Project / type / time / read-state filters
+- Newest-first list with mark-all-seen
+- Sidebar badge reflects unified unread count (server-side)
+
+Slice B + C are layer cake on top with no schema or substrate changes.
+
+---
+
+## 8. Out of scope
+
+- **Push notifications.** Telegram / WhatsApp / email — different
+  channel concerns, separate design.
+- **Cross-user inbox views.** No "admin sees others' inboxes" in v1.
+- **Pinning / starring items.** Not in m's ask. If feedback after Slice
+  A wants it, opens its own design.
+- **Paliadin chat unread.** Not part of project_events; paliadin lives
+  in its own pane. Slice C could surface a banner if asked.
+- **Replacement of the existing /api/inbox/{pending-mine,mine} endpoints.**
+  They stay because the dashboard's `loadInboxSummary` uses them and
+  no benefit to consolidating.
+- **Detail-page changes.** Clicking a project_event row in the inbox
+  navigates to the existing entity detail page (deadline, appointment,
+  note); we don't build a new "event detail" view.
+- **InboxSummary on the dashboard.** Out of Slice A. Slice C upgrades
+  it; for now the widget keeps showing approval-only.
+
+---
+
+## 9. Open questions for m
+
+Defaulted to (R) per the inventor protocol — only **Q1** is escalated
+to head for explicit confirmation because it changes the
+inbox's surface area. Everything else falls to the recommended pick
+unless head/m flag otherwise.
+
+**Q1 — Event-type catalogue (material pick, head answered):**
+**LOCKED = A** (curated subset with `*_approval_*` de-dup). Head added
+`member_role_changed` to the curated list with a Slice B narrowing
+follow-up + a coarser `inbox_focus` chip cluster on the bar. Full
+decision recorded in §12.
+
+**Q2 — Time window:** (R) Past30d default + chip cluster
+(today / past_7d / past_30d / past_90d / any) + custom range via the
+existing time picker. Locked unless head overrides.
+
+**Q3 — Read/unread model:** (R) High-watermark cursor
+(`users.inbox_seen_at`). Pending approval_requests carry forward even
+when older than the cursor — guards against burying a high-value
+approval. Per-item dismiss is Slice C, opt-in. Locked.
+
+**Q4 — Filters surfaced on the bar:** (R) time / project /
+approval_viewer_role / approval_status / approval_entity_type /
+project_event_kind / unread_only / shape / sort / density. Locked
+unless head wants `source` (approvals-only vs events-only chip)
+added — defaulting to "not in v1".
+
+**Q5 — View toggle parity with /events:** (R) list (default — newest
+first) / cards (day-grouped) / calendar (date-point). Wired via the
+filter-bar's existing `shape` axis, not a per-page selector. Locked.
+
+**Q6 — Architecture:** (R) Reuse `view_service.RunSpec` with both
+sources in the InboxSystemView spec; no new aggregation service.
+Approval-event de-dup applied in `runProjectEvents`. Locked.
+
+**Q7 — Notification badge:** (R) Yes — Slice A makes the existing
+`/api/inbox/count` return the unified unread count; sidebar badge
+client unchanged. Locked.
+
+**Q8 — Acknowledgement flow:** (R) Approval rows keep
+approve/reject/revoke buttons inline (list shape only). project_event
+rows have no inline action — click row → navigate to the underlying
+entity. Cursor advance is via "Alles als gelesen markieren" only —
+no per-row mark-read in v1. Locked.
+
+**Q9 — Empty-state copy:** (R) "Keine Neuigkeiten in den letzten 30
+Tagen." (DE primary) / "No updates in the last 30 days." (EN). The
+existing admin nudge for unseeded approval_policies stays untouched.
+Locked.
+
+---
+
+## 10. Risks + mitigations
+
+- **Performance.** `runProjectEvents` reads up to LIMIT 500 rows per
+  user-call; with two sources unioned + 30-day window + visibility
+  predicate this should stay under 50ms on the live shape (project
+  count ~100, events/day low double digits). If
+  it doesn't, partial index hint: `paliad.project_events (created_at DESC)
+  WHERE event_type IN (curated list)` — Slice A optional, add if
+  EXPLAIN shows a seq scan in dev.
+- **De-dup correctness.** Suppressing `*_approval_*` events in the
+  project_event source relies on the approval_request row being the
+  authoritative signal. **Edge case:** a request gets revoked, then
+  re-requested — both audit events exist. Both correspond to a single
+  approval_request row at any moment (the latter via the partial-index
+  upsert). De-dup stays valid.
+- **Cursor advance race.** If two browser tabs both POST mark-all-seen,
+  the second wins (now() wins). Acceptable. If a user reads in tab A
+  then clicks an item in tab B that was created between the two reads,
+  tab A's "Alles als gelesen" advances past that newer item without
+  the user seeing it. Mitigation: server-side, `mark-all-seen` accepts
+  an optional `?up_to=<iso>` so the client can pin to the timestamp of
+  the newest visible row. Slice A wires this.
+- **shape-list factor-out.** Pulling `renderApprovalRow` out of
+  `renderApprovalList` risks regressions on the *current* /inbox. Cover
+  with a snapshot/golden test on the approval row markup in Slice A
+  before the dispatch change.
+- **Sidebar bell badge cap.** Current code clamps at "9+". Once we add
+  project_events, the count can easily exceed 100. Keep the "9+" clamp
+  for visual reasons — but make the page header show the *exact* count
+  ("123 neu") so the user knows what's behind it.
+- **Q1 fallback.** If head doesn't reply before Slice A coder shift
+  starts, the (R) pick A locks. If head later picks B or C, the only
+  change is the `InboxProjectEventKinds` list literal in
+  `filter_spec.go` — no schema impact, no migration change. Cheap to
+  flip.
+
+---
+
+## 11. Build/test verify list (Slice A done-when)
+
+1. `make build` clean.
+2. `go test ./...` passes; new tests cover:
+   - InboxSystemView spec shape includes both sources + curated kinds.
+   - `runProjectEvents` drops `*_approval_*` when ApprovalRequest is in spec.
+   - `UnseenInboxCountForUser` returns expected count for cursor and pending-approval combinations.
+   - POST `/api/inbox/mark-all-seen` updates the column.
+   - URL codec round-trip for `unread_only` axis.
+3. Inbox loads at `/inbox` with project-event rows interleaved with
+   approval rows in date-desc order.
+4. "Nur ungelesen" chip toggles between unread (with pending-approval
+   carve-out) and full feed.
+5. "Alles als gelesen markieren" advances cursor; bar refreshes;
+   badge clears (except for any still-pending approvals).
+6. Sidebar bell badge count is the unified number (approval + unread events).
+7. Existing approve/reject/revoke + suggest-changes flows on inbox
+   rows still work unchanged.
+8. `?tab=mine` legacy redirect still hits the right state.
+9. Bilingual labels render (DE/EN toggle).
+
+That's the doneness bar for Slice A.
+
+---
+
+## §12 — m's decisions (head 2026-05-25 11:30)
+
+Head replied to the `mai instruct head` escalation; folded in below.
+
+**Q1 (Event-type catalogue): A — locked.** Curated subset with
+`*_approval_*` de-dup. Tracks Verlauf, matches m's framing ("new events
+that relate to one's projects"), avoids double-counting approval audit
+events against the approval_request row.
+
+Locked InboxProjectEventKinds:
+
+- IN: `project_archived`, `project_reparented`, `project_type_changed`,
+  `deadline_created`, `deadline_completed`, `deadline_reopened`,
+  `deadline_updated`, `deadline_deleted`, `deadlines_imported`,
+  `appointment_created`, `appointment_updated`, `appointment_deleted`,
+  `note_created`, `our_side_changed`, **`member_role_changed`**
+  (added by head — see refinement #1).
+- OUT (audit duplicates of approval_requests): every `*_approval_*` event.
+- OUT (too granular / authoring noise): `status_changed`,
+  `project_created`, `checklist_*`.
+
+**Refinement 1 — `member_role_changed` visibility predicate.**
+Head wants this kind included but narrowed: surface the row only when
+the role change applies to the **viewer themselves** or someone above
+them in the project tree (i.e. impacts the viewer's permissions / chain
+of command), not when it's a peer's role changing on a project the
+viewer happens to see.
+
+- Slice A: include `member_role_changed` in
+  `InboxProjectEventKinds` without the narrowing predicate. The row
+  will appear for everyone who can see the project — over-surfacing but
+  not wrong. This keeps Slice A's MVP scope tight.
+- Slice B: add a per-row narrowing filter on top of the inbox source
+  (likely a small extension to `runProjectEvents` that, when
+  `event_type='member_role_changed'`, inspects `metadata.affects_user_id`
+  + walks the project-membership predicate before emitting). The
+  metadata shape is already written by the responsible handler; verify
+  + lock the filter in B.
+
+Q2-Q9 all default to (R) per the inventor protocol.
+
+**Refinement 2 — Filter chip copy.**
+For the visible chip cluster in the bar, head wants user-readable groupings,
+not raw event-kind names. The bar today exposes `project_event_kind`
+as one chip per kind (rendered via the
+`event.title.<kind>` i18n key). For the inbox surface, surface a
+**coarser grouping chip cluster** ahead of that:
+
+- "Genehmigungen" — narrows to `Sources=[approval_request]` only.
+- "Genehmigungen + Termine" — adds appointment_* event_kinds + the
+  approval_entity_type=appointment slice of approvals.
+- "Genehmigungen + Fristen" — adds deadline_* event_kinds + the
+  approval_entity_type=deadline slice of approvals.
+- "Alles" — default; both sources, full curated kinds list.
+
+Implementation: a new axis `inbox_focus` (Slice A, additive — replaces
+the lower-level `project_event_kind` chip's *default visibility* in the
+inbox UI; advanced users still see `project_event_kind` if they expand
+the bar). The four values map to FilterSpec overlays that tweak
+`Sources` + per-source `EventTypes`. Coder owns the exact chip-text
+final copy and the placement (probably first axis in `INBOX_AXES`).
+
+The lower-level `project_event_kind` chip stays in `INBOX_AXES` as an
+advanced override for power users — when active, it overrides the
+`inbox_focus` chip's per-kind defaults.
+
+---
+
+### What changes for Slice A as a result
+
+Doc deltas vs the draft text above:
+
+1. **§2 / §6.1:** add `member_role_changed` to InboxProjectEventKinds.
+   Note Slice B narrowing follow-up.
+2. **§4 / §5:** front of the bar gets a new `inbox_focus` axis
+   (4 chips: Alles / Genehmigungen / +Termine / +Fristen). Default
+   "Alles". `project_event_kind` stays available as an advanced chip,
+   visible after the user expands the bar's overflow section.
+3. **§7 Slice A task list:** add task —
+   "**12a.** New `inbox_focus` axis (`filter-bar/types.ts`,
+   `axes.ts`). FilterSpec overlay translates the chip value to a
+   `(Sources, ProjectEventPredicates.EventTypes, ApprovalRequestPredicates.EntityTypes)`
+   triple. URL codec round-trips."
+4. **§11 Slice B done-when:** add — "`member_role_changed` narrowing
+   predicate is in place; rows surface only when the change affects
+   the viewer's permissions chain."
+
+No schema changes from the head's adjustments. The `inbox_focus` axis
+is a pure UI/overlay primitive; nothing about the InboxSystemView spec
+schema moves.

+--
+-- BEFORE this migration, the de.inf.lg rules for Replik and Duplik
+-- had parent_id = NULL with duration_value = 4 weeks each. The
+-- projection therefore anchored both off the proceeding's trigger
+-- date (Klageerhebung) and added 4 weeks → both rows rendered at the
+-- same calendar date, BEFORE Klageerwiderung (which sits at
+-- Klageerhebung + 6 weeks per § 276 Abs. 1 S. 2 ZPO).
+--
+-- Correct ZPO sequence for first-instance infringement before the
+-- Landgericht is:
+--
+--   Klageerhebung (§ 253 ZPO)
+--     → Anzeige der Verteidigungsbereitschaft (§ 276 Abs. 1 S. 1 ZPO,
+--       2 Wochen ab Zustellung der Klage)
+--     → Klageerwiderung (§ 276 Abs. 1 S. 2 + § 277 ZPO; vom Gericht
+--       gesetzte Frist von mindestens 2 Wochen, in der Praxis 6 Wochen)
+--     → Replik (vom Gericht gesetzte Frist; Anordnungskompetenz aus
+--       § 273 ZPO, prozessuale Förderungspflicht der Parteien aus
+--       § 282 ZPO; in der Praxis ~ 4 Wochen ab Zustellung der

+--       Praxis ~ 4 Wochen ab Zustellung der Replik)
+--
+-- Replik and Duplik have NO statutory period — the Landgericht fixes
+-- the period in its prozessleitende Verfügung. We model them as
+-- is_court_set = true with a placeholder 4-week duration anchored on
+-- the immediately preceding filing so the timeline (a) renders them
+-- in strict chronological order and (b) gives the lawyer a sane
+-- notional date that can be overridden via "Datum setzen" once the
+-- court issues the actual period.
+--
+-- legal_source set to DE.ZPO.273 (Vorbereitung des Termins —
+-- court's case-management power that authorises setting Replik /
+-- Duplik periods). The full citation chain (§§ 273, 282 ZPO) lives
+-- in deadline_notes so the rendered card explains the source.

+-- t-paliad-266 / m/paliad#97 — make cross-cutting trigger pills filter
+-- by court system in the event-type / Fristen search modal.
+--
+-- Two things land here:
+--
+--   1. DATA — backfill the missing deadline_rules row for trigger 207
+--      (Wegfall des Hindernisses, UPC R.320). Mig 063 added the
+--      trigger_event but never seeded its event_deadlines counterpart;
+--      mig 092 then dropped event_deadlines after copying the four
+--      sibling Wiedereinsetzungen (ids 200..203) into deadline_rules,
+--      so trigger 207 stayed orphaned with no duration / legal_source.
+--      Adding the row makes UPC R.320 Wiedereinsetzung calculable on
+--      par with the four siblings (2 months from removal of obstacle,
+--      legal_source = 'UPC.RoP.320', party = 'both') and gives the
+--      matview a legal_source to surface for the UPC trigger pill.
+--      Pattern mirrors the four sibling rows mig 085 inserted.
+--
+--   2. MATVIEW — rebuild paliad.deadline_search with a LEFT JOIN on
+--      paliad.deadline_rules for trigger pills, exposing the trigger's
+--      legal_source on the row. The cross-cutting concept card pills
+--      then carry a structured citation prefix (UPC.* / DE.ZPO.* /
+--      DE.PatG.* / EU.EPC* / EU.EPÜ.*) that the search service can
+--      match against the active forum-bucket filter — see
+--      DeadlineSearchService.translateForums + ForumToLegalSourcePrefixes
+--      (added in this same change). Without the matview surfacing
+--      legal_source for trigger rows, every cross-cutting sub-row
+--      ignored the court-system chip selection (the bug m reported).
+--
+-- The materialised view paliad.deadline_search refreshes on the next
+-- server boot via services.RefreshSearchView (cmd/server/main.go), so
+-- the new legal_source column for triggers becomes searchable as soon
+-- as the deploy restarts the process. No matview refresh from the
+-- migration itself.

+-- (curie's bulletproof completeness audit, merged 2026-05-25 as commit
+-- 94a9e7e). 16 distinct single-row UPDATEs across UPC + DE-LG + DPMA +
+-- EPA proceedings; T0.5 + T0.6 were shipped separately as mig 124
+-- (m/paliad#95, de.inf.lg Replik/Duplik sequencing) and are not
+-- repeated here. T0.8 (covered by T0.2) and T0.11 (covered by T0.1)
+-- are dedup'd out per the audit's own note.
+--
+-- Also folds in m/paliad#99 (UPC Statement of Claim missing legal
+-- citation): upc.inf.cfi.soc.rule_code / legal_source backfilled to
+-- UPC RoP R.13(1). Same migration file, separate UPDATE block with
+-- its own guard.
+--
+-- All fixes within the existing schema (no new columns). Each UPDATE
+-- is guarded by a WHERE clause that matches only the pre-fix row
+-- state (per mig 095 convention) — re-applying against a DB that
+-- already carries the fix matches zero rows and no-ops, so there are
+-- no duplicate deadline_rule_audit entries on idempotent re-runs.
+--
+-- Verification DO block at the end RAISEs EXCEPTION if any of the
+-- patched rows is left in an inconsistent shape (mixing pre-fix and
+-- post-fix state).
+--
+-- audit_reason set_config required at the top — the mig 079 trigger
+-- on paliad.deadline_rules raises EXCEPTION 'audit reason required'
