+-- persons had no ON DELETE behaviour. Any other delete path (a future endpoint, a manual

+-- documents rows — a cascade into documents would destroy historical letters. sender_id is
+-- SET NULL (documents.senderText preserves the raw textual attribution); the receiver join

+--
+-- No NOT VALID + VALIDATE two-step: these tables are small (thousands of rows → sub-second
+-- ACCESS EXCLUSIVE lock). Do NOT copy this drop-and-recreate pattern onto a large table.
+--
+-- Not audit-logged: a DB ON DELETE cascade runs below AuditService — a known, accepted trade.

The iterative fallback heuristic never overrides a seeded rank, and spouse-pulldown never pulls a seeded rank — only unseeded nodes (no `generation`) flow through the heuristic.
 
-**sibling block** — a layout unit holding the children of a single parent-set at one generation, used inside `buildLayout.ts`. Each block has a center computed from the parents' midpoint; blocks are then packed left-to-right within a generation row. Two adjacent sibling blocks at the same rank can be merged if a `SPOUSE_OF` edge crosses them (intra-family marriage, AC2).
+**family forest** — the model the Stammbaum horizontal layout reasons over (ADR-030, `familyForest.ts`): a forest of **units** rather than per-generation rows. Replaces the old per-generation "sibling block" packer. The canonical fixture is ~24 root units over 62 nodes.
 
-**loose spouse** — a person at a given generation who is a spouse of someone in a sibling block but is not themselves a parented child of anyone in the graph. Loose spouses are attached adjacent to their parented partner (right side per Leonie's UX rule) so the spouse line stays short.
-_Not to be confused with [parented](#parented-layout)_ — loose is the absence of parent edges into the graph.
+**unit** `[layout]` — one bloodline carrier (the **primary**) plus the spouse(s) absorbed into its run, rendered as one adjacent row of cards. `members[0]` is the primary; the rest are spouses in marriage-year order (#361). A lone person is a unit of one. A unit's children are the units anchored by the couple's offspring. The unit — not the individual — is the node the tidy-tree packs.
 
-**parented** `[layout]` — a layout flag on a sibling-block member indicating that the person has at least one `PARENT_OF` edge incoming from a node already in the graph at the prior generation. Parented members are the layout anchors of their block (the block is centred so the average index of parented members sits under the parents' midpoint); non-parented members (loose spouses) ride along on the side.
+**tidy tree** — the bottom-up Reingold–Tilford contour packer (`tidyTree.ts`) that assigns each unit's horizontal `x`: lay out child subtrees first, pack them so their contours clear by `COL_GAP` at every level, then centre the unit over the span of its children. Contours are indexed by absolute generation level, so unrelated roots at different generations share x-columns. `x` comes from structure; `y` still comes from rank (`assignRanks`, #689).
 
-**anchor index** — within a sibling block, the average position of `parented` member indices. The block is shifted horizontally so this index, multiplied by `NODE_W + COL_GAP`, lines up under the midpoint of the block's parents — keeping every parent-child connector orthogonal (90°).
+**structural owner** — for a couple, the spouse that keeps the bloodline (hierarchy) position: lower `birthYear`, then stable `id` (`pickStructuralOwner` in `familyForest.ts`). The other spouse is absorbed into the owner's run. Reused by the cross-link, cycle, and intra-family paths so the rule is defined once.
 
-**intra-family marriage** — a `SPOUSE_OF` edge where both endpoints are parented members of _different_ sibling blocks at the same rank (i.e. both have parents in the graph, but the parent sets differ). Layout merges the two blocks so the spouses sit adjacent at the join boundary; latent in current data (0 cases in the May-2026 canonical snapshot) but covered by a synthetic regression test in `buildLayout.test.ts`.
+**loose spouse** — a person who marries into the graph with no `PARENT_OF` edges of their own. They are absorbed into their partner's unit run (no ancestor subtree), but any children of theirs still anchor through the couple unit.
+
+**bloodline** — the set of people reachable from a root unit via structural-owner `PARENT_OF` edges; renders as one contiguous horizontal band with no foreign node interleaved (the contiguity invariant that fixed the smeared-bloodline bug, #724).
+
+**cross-link** `[layout]` — a `PARENT_OF` edge whose child is positioned in a spouse's run elsewhere (a cross-level intra-family marriage). The connector draws it with a distinct `2 6` dash at reduced opacity — never the `4 4` ended-marriage cadence — with geometry still landing on the child (WCAG 1.4.1).
+
+**intra-family marriage** — a `SPOUSE_OF` edge where both endpoints have parents in the graph. The couple is always exactly adjacent in the owner's run; when the two spouses' parents sit at the same structural level the displaced parent edge stays solid (the adjacency case), otherwise it renders as a cross-link. The canonical fixture has two such marriages (Walter⚭Eugenie, Clara⚭Herbert), covered in `buildLayout.test.ts`.
 
 **marriage dot** — the SVG circle drawn at the midpoint of a `SPOUSE_OF` connector in the Stammbaum tree (`StammbaumTree.svelte`). Radius is `r=6` (12 px diameter) so the marker meets WCAG 1.4.11 (3:1 non-text contrast) when it stacks to disambiguate multiple marriages on the same focal person.

As part of #553 we migrated `EnrichmentBlock.svelte` from `$app/stores.navigating` to `$app/state.navigating` with `!!navigating.type` — matching the pattern already established in `routes/aktivitaeten/+page.svelte:117` and `routes/documents/+page.svelte:261`. Migration eliminated the *need* to mock a store at all in that spec.

 **Pattern note:** When an overlay or dropdown triggers a navigation action, use `<button type="button">` with an `onclick` handler that calls `goto(path)` — do **not** use `<a href="…">` with `e.preventDefault()`. SvelteKit registers its link interceptor as a capture-phase `document` listener, so it fires before the component's bubble-phase `onclick`. By the time `e.preventDefault()` runs the router has already initiated navigation, which tears down the vitest-browser Playwright orchestrator iframe. A `<button>` carries no `href`, so the capture-phase interceptor never fires. See `NotificationDropdown.svelte` for the canonical example.

+## Revision 2026-06-02 (#560 — shared mock bodies, no-factory ban)
+
+### No-factory `vi.mock` of a virtual module is forbidden
+
+PR #657 attempted to delete `vi.mock` factories entirely and rely on Vitest auto-resolving a bare `vi.mock('$app/navigation')` to an adjacent `src/__mocks__/$app/navigation.ts`, the way Jest's `__mocks__/` directory works. **This is empirically false for SvelteKit virtual modules in browser-mode Vitest.** A no-factory `vi.mock(virtualModule)` substitutes _some_ exports (plain function references like `goto`) but leaves others bound to the live implementation — notably `replaceState`, which SvelteKit re-exports through a getter delegating to the live router. CI #1857 failed on `admin/tags/[id]` with `Cannot call replaceState(...) before router is initialized`, raised from a `$effect`. A partial auto-mock is therefore unsafe.
+
+**Rule:** under `**/*.svelte.{spec,test}.ts`, a `vi.mock` of a virtual module must always pass a factory. The factory body must still be synchronous (the original binding invariant above). Enforced by a seventh layer:
+
+7. **In-suite no-factory-ban meta-test** at `frontend/src/__meta__/no-factory-ban.test.ts` — same source-scan mechanism as the other meta-tests; fails if any browser spec contains a `vi.mock('mod')` with no second argument.
+
+### Cross-file sharing of a virtual-module mock body is infeasible (the third false premise)
+
+The original #560 plan ("Option A") proposed deduplicating the non-trivial interceptor factories by importing a shared body from `src/__mocks__/` into a sync factory:
+
+```ts
+import * as formsMock from "$mocks/$app/forms";
+vi.mock("$app/forms", () => ({ ...formsMock }));
+```
+
+**CI proved this does not work in `@vitest/browser-playwright` 4.1.6**, across two runs:
+
+1. The static-import form above fails at runtime — vitest hoists `vi.mock` _above_ the import, so the factory references an uninitialised binding: `vi.mock factory: make sure there are no top level variables inside, since this call is hoisted`.
+2. The documented escape, loading the body through an async hoisted import, fails to even parse in browser mode — vitest's hoist transform mangles it: `SyntaxError: Unexpected identifier 'vi'`.
+
+   ```ts
+   const formsMock = await vi.hoisted(() => import("$mocks/$app/forms")); // parse error in browser mode
+   ```
+
+`vi.hoisted` has the _same_ constraint as `vi.mock` (its factory can't reference top-level imports either, since it too is hoisted above them), so there is no way to get an external module's body into the hoisted context here. **Therefore: do not share virtual-module mock bodies across spec files. Define each `vi.mock` factory inline, with a synchronous body.** Duplicating the handful of interceptor factories is the accepted cost — it is the only pattern that works. The `src/__mocks__/$app/*` modules and the `$mocks` alias added for Option A were removed. (Revisit on a newer `@vitest/browser-playwright` whose hoist transform handles async `vi.hoisted` imports.)
+
+The no-factory-ban above still stands: every `vi.mock` of a virtual module must pass an _inline_ sync factory — never no factory, never a spread of an imported binding.
+
+### Rejected: Option C (config-level auto-resolve)
+
+Re-enabling implicit `__mocks__/` auto-resolution through a Vitest config flag or a `setupFiles` shim was rejected. It trades auditability for cosmetics: the mock binding becomes a hidden default invisible at the call site, and its failure mode (a partial mock) is the hardest to debug — exactly the PR #657 class. The no-factory-ban meta-test deliberately keeps the door closed.
+
+### Patch pin
+
+`@vitest/browser-playwright` is exact-pinned (no caret) to `4.1.6` in `package.json` so `patches/@vitest+browser-playwright+4.1.6.patch` keeps applying; a caret range could float onto a version the patch rejects. Pin and patch are both removed once the library ships a release containing [PR #10267](https://github.com/vitest-dev/vitest/pull/10267).

+# ADR-028 — pdf.js wasm decoders are served same-origin; a future CSP must allow them
+
+**Date:** 2026-06-01
+**Status:** Accepted
+**Issue:** #708 (scanned PDFs with CCITT/JBIG2 images render blank)
+**Milestone:** Pre-prod read-path hardening
+
+---
+
+## Context
+
+pdf.js 5.x moved the **JBIG2, CCITTFax, and JPEG2000 image decoders into
+WebAssembly**. A single `jbig2.wasm` module decodes both JBIG2 and CCITTFax;
+`openjpeg.wasm` decodes JPEG2000. These modules live in
+`node_modules/pdfjs-dist/wasm/` and are not on the web path by default, and
+`getDocument` will not load them unless it is given a `wasmUrl`. Without that,
+bi-level black-and-white scans (CCITT G4 fax — ~16% of the archive) painted a
+blank canvas in production while JPEG scans rendered fine.
+
+Two cross-cutting, long-lived constraints fall out of the fix and are not
+obvious from reading any single file — hence this record.
+
+## Decision
+
+1. **Serve the pdf.js wasm from our own origin**, at the unversioned path
+   `/pdfjs-wasm/`, copied from `node_modules/pdfjs-dist/wasm/` into
+   `build/client/` at build time by `vite-plugin-static-copy` (a devDependency;
+   see `frontend/vite.config.ts`). `getDocument` is called with
+   `wasmUrl: '/pdfjs-wasm/'`. **Never point `wasmUrl` at a public CDN** — a
+   decoder on the core read path must not become a supply-chain RCE surface.
+
+2. **Any future `Content-Security-Policy` MUST include
+   `script-src 'wasm-unsafe-eval'` and `worker-src 'self' blob:`.** pdf.js
+   instantiates WebAssembly and runs its renderer in a worker created from a
+   `blob:` URL. A CSP without these directives silently re-breaks PDF rendering
+   for the exact class of documents #708 fixed. No CSP is set today
+   (`infra/caddy/Caddyfile` `(security_headers)`); the Caddyfile carries a
+   pointer to this ADR so the future CSP author cannot miss it.
+
+3. **The wasm shipping is guarded at build time.** `frontend/postbuild`
+   (`scripts/assert-pdfjs-wasm.mjs`) fails the build loudly if `jbig2.wasm` or
+   `openjpeg.wasm` is absent from `build/client/pdfjs-wasm/` — so a future
+   `pdfjs-dist` bump that renames or relocates the wasm cannot regress to a
+   blank canvas unnoticed. This runs in CI and in the Docker build stage.
+
+## Consequences
+
+- The decoders load from the same origin as the app — no third-party trust, no
+  SRI to manage, correct `Content-Type: application/wasm` served by
+  adapter-node.
+- `/pdfjs-wasm/` is **not** content-hashed, so it must not be served
+  `immutable` — a revalidating cache avoids serving a stale `.wasm` against a
+  newer worker after a pdfjs upgrade.
+- The CSP constraint is a standing obligation on whoever introduces a CSP. If
+  that work happens, this ADR and the Caddyfile note are the source of truth.
+- No new container or external system is introduced, so the C4 L1/L2 diagrams
+  are unaffected; `/pdfjs-wasm/` is a static asset served by the existing
+  frontend container.
+- Render/decode failures are no longer silent: the viewer surfaces a localized
+  message plus a working download link (see #708).

+# ADR-029: Composite actions for cross-workflow deploy logic
+
+## Status
+
+Accepted
+
+## Context
+
+The `nightly.yml` (staging) and `release.yml` (production) workflows shared three
+blocks of deploy logic verbatim: the four observability-stack steps (deploy configs,
+validate, start, assert health), the Caddy reload step, and the public-surface smoke
+test. The only per-environment differences were secret names (`STAGING_*` vs `PROD_*`),
+the `POSTGRES_HOST` value, and the smoke-test hostname.
+
+This duplication was held together by `# Keep in sync with nightly.yml` comments — an
+honour-system invariant. Any change (a new healthchecked service, a different rsync flag,
+a new secret) had to be applied in two places, and nothing enforced that it was. Issue #603
+documents a real instance: the obs secret set had grown to five keys while a refactor draft
+listed only four.
+
+### Decision drivers
+
+1. Cross-workflow deploy logic must have a single definition, enforced — not a
+   discipline-based "keep in sync" promise.
+2. Per-environment variation must be expressed as explicit, typed inputs, not by forking
+   the whole step block.
+3. The mechanism must work on the existing single-tenant self-hosted Gitea runner with no
+   new infrastructure.
+
+### Alternatives considered
+
+**A: Reusable workflow (`workflow_call`)** — Gitea supports called workflows. Rejected for
+this case: reusable workflows run as a separate job with their own runner context, which
+breaks the in-job, sequential `deploy → reload → smoke` ordering these steps rely on and
+complicates passing the already-checked-out workspace. Composite actions run inline in the
+calling job, preserving step order and the workspace.
+
+**B: Shared shell script invoked from both workflows** — e.g. `scripts/deploy-obs.sh`.
+Rejected: loses the typed-input contract and per-step CI log sections, and reintroduces
+manual argument threading that is as error-prone as the duplication it replaces.
+
+**C: Keep the `# Keep in sync` comments** — status quo. Rejected: unenforced; issue #603
+is direct evidence it fails.
+
+## Decision
+
+Extract the shared logic into three single-responsibility Gitea composite actions under
+`.gitea/actions/`: `deploy-obs` (five inputs), `reload-caddy` (no inputs), and `smoke-test`
+(`host` input). Both workflows invoke each via a single `uses: ./.gitea/actions/<name>` call,
+passing per-environment values as `with:` inputs. This is the repository's first composite
+action and sets the convention; `docs/infrastructure/ci-gitea.md` documents it.
+
+## Consequences
+
+**Positive:**
+- Shared deploy logic has one enforced definition; a change lands once and both
+  environments get it. The `# Keep in sync` comments are deleted.
+- Per-environment variation is a typed input contract, not a forked block.
+- Runs inline on the existing runner — no reusable-workflow job context, no new
+  infrastructure.
+
+**Negative / constraints:**
+- Workflows now depend on a checked-out `.gitea/actions/` tree: `actions/checkout` MUST run
+  before the first `uses: ./…` (a local action does not exist on disk until checkout).
+- Secrets cannot be read from the `secrets.*` context inside a composite action; they must
+  be passed as inputs and mapped to `env:`. The `obs-secrets.env` heredoc therefore uses an
+  unquoted delimiter so `$VAR` expands at the shell layer.
+- The `reload-caddy` pinned alpine digest now lives in the action, not the workflow file —
+  it must be added to Renovate's watch list so it does not go stale.

+# ADR-030 — Removing Briefwechsel trades bidirectional correspondence for a unidirectional search filter
+
+**Date:** 2026-06-02
+**Status:** Accepted
+**Issue:** #716 (remove the Briefwechsel view; retarget its links to document search)
+**Milestone:** —
+
+---
+
+## Context
+
+The standalone **Briefwechsel** view (`/briefwechsel`) was a bilateral letter timeline
+between two `Person`s. It was not in the main navigation; its only inbound product link
+was the "Häufige Korrespondenten" card on a person's detail page. It was backed by a
+dedicated endpoint (`GET /api/documents/conversation`) and two repository queries
+(`findConversation`, `findSinglePersonCorrespondence`) that nothing else used.
+
+The view's data source, `findConversation`, was **bidirectional**: it returned letters
+where `(sender = A AND receiver = B) OR (sender = B AND receiver = A)` — i.e. the
+exchange in both directions. We removed the view entirely (frontend and backend) and
+retargeted the one inbound link into the existing **document search**
+(`/documents?senderId=A&receiverId=B`).
+
+Document search composes its `senderId`/`receiverId` filters with AND
+(`sender.id = A` **AND** `receivers contains B`), so the retargeted link shows **only the
+A→B direction**. The reverse direction (B's replies to A) is no longer surfaced by
+clicking a correspondent.
+
+## Decision
+
+**Accept the behaviour change: the retargeted card link is unidirectional (A→B only).**
+The reverse direction is intentionally dropped rather than preserved with a redirect
+shim or a new bidirectional search filter.
+
+- The card link sets both params (`senderId=A&receiverId=B`); the destination is the
+  consistent, already-tested document search rather than a separate dedicated view.
+- The "×N" badge on each correspondent chip remains **bilateral** — it counts shared
+  letters in both directions as a relationship-strength signal — so the badge may exceed
+  the unidirectional search result count. This is surfaced in the badge's title, not
+  recomputed.
+
+## Consequences
+
+- **Regression:** a reader can no longer reach B→A replies in one click from the
+  correspondents card. They must run a second search with sender/receiver swapped.
+- The bilateral query code (`findConversation`, `findSinglePersonCorrespondence`, the
+  `/api/documents/conversation` endpoint, and the `getConversationFiltered` service
+  method) is fully removed — no dormant dead code.
+- No data migration and no schema change: only query/endpoint code was removed; the
+  `documents`, `persons` and join tables are untouched. The `hasSender`/`hasReceiver`
+  specifications stay — document search still uses them.
+- **Future enhancement (out of scope here):** a bidirectional "between these two people,
+  either direction" document-search filter would restore the dropped direction without
+  reviving the standalone view. If built, it supersedes the unidirectional link.

+# ADR-030 — Stammbaum Bloodline-Contiguous Tidy-Tree Layout
+
+**Date:** 2026-06-04
+**Status:** Accepted
+**Issue:** #724
+**Supersedes:** ADR-026 (in part — the per-generation block-packer decision and its
+position-within-rank fix path; the in-house / no-dagre decision and the seeded-rank
+invariant from #689 are retained)
+
+---
+
+## Context
+
+ADR-026 kept Stammbaum horizontal placement in-house with a **per-generation block
+packer** and pre-committed a successor ADR "if any acceptance criterion stops
+converging in-house." Its single UX stop-trigger was Albert de Gruyter's marriages
+failing the read test.
+
+The block packer hit a worse, structural failure: it placed each generation
+**independently**, centring sibling blocks under already-placed parents and only ever
+**shoving right** on collision. Two consequences followed — a deep branch that could
+not fit at its ideal centre dragged everything downstream rightward and stranded the
+ancestor at the **left edge** of its own descendants; and a parent placed before its
+descendants existed could never be re-centred over them. Extreme symptom: Albert de
+Gruyter (G0) far left, a great-great-grandchild far right — one bloodline smeared
+across the full canvas. That is exactly the "UX failure against the canonical fixture"
+ADR-026 named as the trigger to revisit the layout.
+
+## Decision
+
+**Replace the per-generation block packer with a bottom-up "tidy tree"
+(Reingold–Tilford / Walker contour pack), still in-house, no new dependency.**
+
+The horizontal `x` rewrite is split into three reviewable, unit-tested modules
+(mirroring the `panZoom.ts` / `panZoomGestures.ts` / `animateView.ts` split):
+
+- **`layout/tidyTree.ts`** — domain-agnostic contour packer over abstract
+  `{ id, width, children, level? }` nodes, zero generated-API imports. Contours are
+  indexed by **absolute generation level**, not tree depth, so unrelated roots at
+  different generations share x-columns instead of smearing the forest wide.
+- **`layout/familyForest.ts`** — all genealogy semantics: the **unit** model (a
+  bloodline-carrying primary plus the spouse(s) absorbed into its run),
+  `pickStructuralOwner` (lower birthYear, then stable id), loose-spouse absorption,
+  multi-spouse runs (#361), sibling/branch order (birthYear ASC NULLS LAST →
+  displayName → id), intra-family resolution, and cross-link classification.
+- **`layout/buildLayout.ts`** — orchestrates forest → tidy-pack → per-person
+  positions. `assignRanks` (y from rank, #689 seeding), the `generations` map, and
+  `computeViewBox` are reused **unchanged**; `x` comes from structure, `y` from rank.
+
+Two decisions taken during implementation and confirmed with the maintainer:
+
+1. **Intra-family marriage = hybrid.** A couple is always exactly adjacent in the
+   owner's run. When the two spouses' parents sit at the **same structural level** the
+   displaced parent edge renders as a normal solid connector (the "adjacency" case);
+   when they are **cross-level** (e.g. the canonical Clara⚭Herbert, where one parent
+   is nested under Albert and the other hangs off a separate root), the structural
+   owner keeps the hierarchy edge and the other parent→spouse edge renders as a
+   distinct cross-link.
+2. **Cross-link is rendered with a distinct `2 6` dash at 0.7 opacity** in
+   `StammbaumConnectors.svelte` — never the `4 4` ended-marriage cadence. Geometry
+   still lands on the correct child top, so meaning is carried redundantly (WCAG
+   1.4.1); the 0.7 opacity clears the WCAG 1.4.11 3:1 non-text floor.
+
+## Consequences
+
+### Accepted
+
+- **Ancestor centring** — every unit is centred over its child-units' span (named-bug
+  guard `great_great_grandparent_is_not_stranded_left_of_descendants` + a fixture-wide
+  loop over canonical and synthetic trees).
+- **Bloodline contiguity** — each bloodline is one band with no foreign node
+  interleaved. Albert de Gruyter's bloodline shrank from a full ~4860px smear to
+  ~960px.
+- **#361 / #689 preserved** — multi-spouse runs in marriage-year order, seeded ranks,
+  spouse pull-down; the existing `buildLayout.test.ts` cases stay green.
+- **Determinism** — every comparator ends in a stable id; a seeded permutation of
+  nodes/edges yields byte-identical positions.
+- **Fail-closed on cycles** — `assignRanks`' iteration ceiling plus a forest structure
+  (each unit has ≤1 hierarchy parent, cycles are unreachable from roots) guarantee a
+  finite layout with every node placed exactly once.
+
+### Trade-off — total canvas width replaces the ADR-026 width assumption
+
+Centring every ancestor inherently makes a forest of ~24 root-bands **wider** overall
+than the old per-generation left-packer that interleaved everyone into compact shared
+rows (canonical: ~7960px vs the old ~4860px). Total canvas width is therefore the
+wrong success metric; **per-bloodline span** is. The width regression test asserts
+each contiguous bloodline stays far under the old full-canvas smear. The wider canvas
+is navigated by the pan/zoom from #692 (ADR-027) and is an accepted trade-off for
+readability.
+
+### Operational
+
+- **No CI, image, compose, or dependency change.** Pure frontend layout. The
+  `d3-flextree` escape hatch from #724 was not needed.
+
+### Deferred (follow-ups, per #724)
+
+- Connector legibility at 320px — the issue's "open verification"; a manual
+  `/stammbaum` pass, with a connector-clarity issue spun only if drops/cross-links
+  tangle.

+# ADR-031 — The document title is a shared `document`-package factory, re-synced by an exact match on save and a grammar heuristic on a one-time backfill
+
+**Date:** 2026-06-04
+**Status:** Accepted
+**Issue:** #726 (auto-sync document titles with date/location: save-time + one-time backfill)
+**Milestone:** —
+
+---
+
+## Context
+
+A document title was a string built **once**, at import time, by a private
+`DocumentImporter.buildTitle()` composing `{index} – {dateLabel} – {location}` (index =
+`originalFilename`, date label honest at the row's precision via `DocumentTitleFormatter`,
+location verbatim). Nothing rebuilt it afterwards. When an archivist later corrected a date
+or location in the edit form, the title kept its stale value (e.g. it still read `2028`
+after the date was fixed to `1928`), because the edit form round-trips the stored title
+verbatim and `updateDocument` simply re-persisted it.
+
+Two distinct problems live here:
+
+1. **Going forward**, an edit to date/location must flow into a title that was machine-built
+   — but must never overwrite a title a human wrote.
+2. **The existing backlog** of already-stale titles must be cleaned once. For these rows the
+   pre-edit state is gone, so there is no exact value to compare against.
+
+The composition formula also existed only inside `importing`, which is the wrong owner: a
+title is a `document` concern, and three call sites (import, save-time, backfill) must share
+one rule or they will drift.
+
+## Decision
+
+### 1. One formula, owned by the `document` package (`DocumentTitleFactory`)
+
+Extract the composition into `DocumentTitleFactory` (a `@Component` in the `document`
+package) with `build(Document)`. `DocumentImporter` (package `importing`) now consumes it.
+`DocumentTitleFormatter` moves into `document` alongside the factory (it stays
+package-private; `importing` reaches the formula only through the factory). The direction is
+deliberate: `document` owns the rule, `importing` depends on it — not the reverse. The
+German date *label* remains the deliberate Java/TS dual implementation pinned by
+`docs/date-label-fixtures.json` (#666); this ADR touches the **composition** only and does
+not collapse the frontend `formatDocumentDate`.
+
+### 2. Save-time regeneration is an EXACT match, not a heuristic
+
+In `DocumentService.updateDocument` only (bulk edit is out of scope), capture
+`autoTitleBefore = titleFactory.build(doc)` from the **currently-persisted** state *before*
+any setter runs. Then:
+
+- if the **submitted** title equals `autoTitleBefore`, it was the machine value → rebuild
+  from the new state;
+- otherwise keep the submitted title verbatim (hand-written or freshly typed).
+
+This is an exact old-vs-new comparison — no false positives, no false negatives — relying on
+the edit form round-tripping an untouched title verbatim. `projectedState` mirrors the
+existing setter asymmetry exactly: `documentDate`/`location` overwrite unconditionally (a
+null clears them), while precision/end/raw are taken from the DTO only when non-null and
+otherwise kept from the entity. A blank submission is never persisted (the title is always
+present) — it falls back to the rebuilt auto-title, which always carries at least the index.
+
+### 3. The one-time backlog cleanup is a grammar heuristic, behind an ADMIN endpoint
+
+`POST /api/admin/backfill-titles` (synchronous, under `AdminController`'s class-level
+`@RequirePermission(Permission.ADMIN)`) sweeps every document and, for each whose stored
+title passes the overwrite test, rebuilds it via the factory. Because the pre-edit state is
+gone, the test (`DocumentTitleBackfillMatcher`, used **only** here) is a grammar heuristic:
+after stripping the **literal** index prefix, the remainder must be exactly the index, a
+known date-label form (+ an optional trailing location), or a lone segment equal to the
+document's current location. Prose is left untouched; anything malformed fails closed.
+
+The backfill saves via `documentRepository.save` directly and **never** routes through
+`updateDocument` — following the `backfillFileHashes` precedent — so a mechanical rename does
+not snapshot the whole corpus into `document_versions`. It is idempotent (a second run
+rewrites nothing) and logs one SLF4J-parameterized `scanned/updated/skipped` line; the
+response is `BackfillResult(count)`.
+
+### 4. Edit-form feedback (FR-005)
+
+A localized helper line (de/en/es) under the title input explains that the title is built
+from date/place and that a hand-edit is preserved, wired via `aria-describedby` and shown
+only on the single-document edit form. A live preview was considered and declined.
+
+## Consequences
+
+- The three call sites can never diverge — there is exactly one formula
+  (`NFR-MAINT-001`). Save-time cost is a string build + compare; the backfill is one
+  synchronous transactional sweep over a low-thousands corpus.
+- Security: the index is compared **literally** (`String.startsWith` / `Pattern.quote`)
+  because `originalFilename` is user-controlled and may carry regex metacharacters — an
+  unquoted pattern would be a ReDoS / regex-injection vector (CWE-1333 / CWE-625). The
+  date-label sub-patterns use only bounded, non-nested quantifiers.
+- **File-replaced documents are treated as manual, by design.** The index is
+  `originalFilename`, which `updateDocument` reassigns to the uploaded file's name on a
+  file-replace. After a replace the stored title no longer matches `build(currentState)`, so
+  neither save-time nor backfill rewrites it. This is the accepted fail-safe of overloading
+  `originalFilename` rather than adding a dedicated `catalogIndex` column.
+- The save-time heuristic risk is zero (exact match); the backfill heuristic can, by its
+  documented FR-004 rule, treat `{index} – {valid date label} – {anything}` as machine-built
+  and rewrite the trailing segment. This is the accepted trade for cleaning the backlog
+  without the lost pre-edit state.
+
+## Alternatives considered
+
+- **A dedicated `catalogIndex` column** instead of overloading `originalFilename` — rejected;
+  it adds a migration and a second source of truth for the index for no current benefit, and
+  the file-replace fail-safe is acceptable.
+- **A heuristic at save-time too** (instead of the exact match) — rejected; the stored title
+  is available pre-edit, so an exact comparison is strictly better (no false positives).
+- **A live title preview in the edit form** — rejected (FR-005); a static helper line is
+  calmer for the 60+ audience and avoids a second client-side mirror of the formula.
+- **Collapsing the frontend `formatDocumentDate` into the backend** — out of scope; the
+  Java/TS date-label split is the deliberate #666 design, pinned by a shared fixture.

+# ADR-032 — Person-delete referential integrity lives in the database, and the cascade never reaches `documents`
+
+**Date:** 2026-06-06
+**Status:** Accepted
+**Issue:** #684 (move person-delete FK detach to database-level `ON DELETE`)
+**Milestone:** —
+
+---
+
+## Context
+
+Deleting a `Person` had to detach the two FKs into `persons` that lacked any `ON DELETE`
+behaviour: `documents.sender_id` and `document_receivers.person_id` (both from V1).
+`PersonService.deletePerson` and `mergePersons` did this in Java — nulling the sender and
+deleting receiver join rows before `deleteById` — so the integrity guarantee lived in
+application code. Any other delete path (a future endpoint, a manual `psql`, a batch job)
+could still orphan rows or fail with an FK-violation 500.
+
+A related soft reference made it worse: `transcription_block_mentioned_persons.person_id`
+was a UUID column with **no FK** (V56, a deliberate "no FK" choice), so a person delete left
+dangling `@`-mention rows. The literal `@DisplayName` lives in `transcription_blocks.text`,
+so only the *link* was ever at stake — not the visible name.
+
+## Decision
+
+Move person-delete integrity into the database (migration V71) and thin the service to a
+plain `deleteById`:
+
+- `documents.sender_id` → `ON DELETE SET NULL` (`documents.senderText` preserves the raw
+  textual attribution, so nulling the link loses no historical record).
+- `document_receivers.person_id` → `ON DELETE CASCADE` (the symmetric completion of V14,
+  which gave the `document_id` side the same).
+- `transcription_block_mentioned_persons.person_id` → a real FK with `ON DELETE CASCADE`,
+  reversing V56's "no FK" decision. The read renderer already degrades a `@DisplayName` with
+  no sidecar row to plain escaped text, so removing the link is invisible to the reader.
+
+**Cascade-boundary invariant:** the cascade stays strictly at the join/reference layer and
+**never reaches `documents` rows** — a cascade into `documents` would destroy historical
+letters. This is pinned by a non-negotiable document-survival assertion in
+`PersonRepositoryTest`.
+
+## Consequences
+
+- A person delete is safe from every path, not just `PersonService`. The service and merge
+  stay thin (`deleteById` + the cascade); `reassignSenderToNull` and `deleteReceiverReferences`
+  are deleted.
+- This *fixes* the pre-existing dead-link-on-deleted-person case — it is not a purely
+  invisible refactor. Note the read renderer strips the `@` prefix when it emits a live
+  mention link, but the degraded (deleted-person) path leaves the literal `@Name` in the
+  block text as-is — the reader sees `@Auguste Raddatz` as plain text, never a dead link.
+- DB cascades run below `AuditService`, so the row-level cleanup is intentionally not
+  audit-logged; the person-delete action itself is still logged at the service layer.
+- The V71 FK validation requires cleaning pre-existing orphan mention rows first; the
+  migration does this in a `DO` block that logs the purge count via `RAISE NOTICE`.
+
+## Alternatives considered
+
+- **Keep integrity in Java** — rejected; it only protects the one code path and re-breaks the
+  moment a second delete path appears.
+- **Cascade `documents.sender_id`** — rejected; it would delete historical letters when a
+  sender is removed. `SET NULL` keeps the letter and its `senderText`.
+- **Leave the mention sidecar FK-less (honour V56)** — rejected; the "no FK" rationale was
+  stale, the name survives in the block text regardless, and the FK removes the orphan-row
+  class of bug.

+# ADR-033 — Tag-name resolution tolerates case-collisions: exact-case first, then a deterministic lowest-id fallback, and never a `unique(lower(name))` constraint
+
+**Date:** 2026-06-06
+**Status:** Accepted
+**Issue:** #730 (document with a case-colliding tag cannot be saved — `findByNameIgnoreCase` `NonUniqueResultException`)
+**Milestone:** —
+
+---
+
+## Context
+
+`TagService.findOrCreate(name)` is the single point that turns a tag **name** into a `Tag`
+row. The document edit form, bulk-edit, and the upload batch all round-trip tag **names**
+(the edit form sends `tags.map(t => t.name).join(',')`) and re-resolve them on **every**
+save through `resolveTags → findOrCreate`. The old implementation resolved with
+`tagRepository.findByNameIgnoreCase(name)`, a derived query returning `Optional<Tag>`.
+
+That signature encodes an invariant the data does **not** hold: that a name is globally
+unique case-insensitively. The canonical tag tree legitimately contains names that differ
+only by case — a parent container and its same-named lowercase **child** (`Geburt` /
+`Geburt/geburt`, `Weihnachten` / `Weihnachten/weihnachten`, …), or two siblings
+(`Reise/Reisepläne` / `Reise/reisepläne`). Each is a distinct node with its own
+`source_ref` (the stable identity, per ADR-025) and its own document attachments — **not** an
+accidental duplicate. When two rows matched case-insensitively, Hibernate threw
+`NonUniqueResultException` → `IncorrectResultSizeDataAccessException` → a generic HTTP 500.
+
+The effect was severe and opaque: every document carrying one of ~10 colliding tags (≈180
+document-tag attachments on staging) became **un-editable** — any field change failed on save
+because the whole tag set is re-resolved — and the user saw only "an unexpected error", with
+no hint that a tag was the cause.
+
+This is a **lookup** problem, not a data problem: the collisions are valid canonical nodes
+and must be preserved.
+
+## Decision
+
+### 1. Resolution is exact-case first, then a non-throwing deterministic fallback
+
+`findOrCreate` resolves in three ordered steps and never throws on a collision:
+
+1. `findByName(cleanName)` — **exact-case** derived query. If present, return it. The edit
+   round-trip replays the stored name verbatim, so the exact-case row is the right binding
+   (typing the bare child name `weihnachten` binds to the child; `Weihnachten` binds to the
+   parent container).
+2. else `findAllByNameIgnoreCase(cleanName)` — the **plural** case-insensitive list. If
+   non-empty, return the element with the **lowest `id`** (`min(comparing(Tag::getId))`).
+3. else create the tag (an orphan: null `sourceRef`/`parentId`).
+
+The two repository methods are deliberately **two distinctly-named methods** — Spring Data
+cannot disambiguate an `Optional<Tag>` from a `List<Tag>` derived query by return type alone.
+The throwing `Optional<Tag> findByNameIgnoreCase` is **deleted** so the non-unique-throwing
+call cannot be reintroduced; `findOrCreate` was its only production caller.
+
+### 2. The tie-break is `id`, and it is load-bearing
+
+`id` is a stable, always-present, unique column, so "lowest id" is a total, deterministic
+order over the candidates: the same name resolves to the same row on every call, forever,
+without throwing. This matters only in the free-text authoring path (step 2), where no
+exact-case row exists yet two case-folding rows do.
+
+### 3. No `unique(lower(name))` constraint — and a load-bearing comment says so
+
+A global case-insensitive uniqueness constraint is **wrong**: it would reject the legitimate
+parent/child canonical nodes. It would also **fail to apply** against the existing rows,
+turning a code-only deploy into a failed Flyway migration that blocks startup. A comment at
+both `findOrCreate` and the repository methods records this so the constraint is not "helpfully"
+added later.
+
+## Consequences
+
+- **Code-only, zero migration, fully reversible** (roll back the JAR). No tag data is touched;
+  the colliding rows stay exactly as the canonical importer produced them.
+- One change fixes all three write paths — single-document edit, bulk-edit, and upload batch —
+  because they all funnel through `resolveTags → findOrCreate`, which stays the single source
+  of truth (resolution logic is **not** hoisted into `DocumentService`).
+- **Free-text tag semantics under collision are accepted as-is** (issue #730, option A): the
+  bare word `weihnachten` binds to the deep child and `Weihnachten` to the parent container.
+  Correct for the edit round-trip and acceptable for authoring; making the typeahead show the
+  tree path so an author can tell a container from its same-named child is a separate
+  follow-up.
+- The wire response stays opaque: after the fix this path no longer throws
+  `IncorrectResultSizeDataAccessException`, and `GlobalExceptionHandler`'s generic handler maps
+  any stray one to `INTERNAL_ERROR` with no Hibernate/SQL leak — so no dedicated handler was
+  added.
+- **The sibling Person path is fixed the same way — see the Person extension below (#731).**
+- Postgres `LOWER()` folding of umlauts (`ü`/`ä`) is the actual correctness hinge of the
+  fallback and cannot be proven by a mocked repo, so it is pinned by a Testcontainers
+  `postgres:16-alpine` test on a `Glückwünsche`/`glückwünsche` pair; a plain-ASCII test would
+  stay green while the bug reappeared for umlaut tags.
+
+## Person extension (#731)
+
+The Person domain carried the same latent throw on **two** user-influenced lookup surfaces, and
+is fixed with the same exact-case-first, non-throwing pattern — but with a deliberately
+**different fallback per surface**, because the two paths have different consequences.
+
+- **Alias path — `PersonService.findOrCreateByAlias` — deterministic lowest-id (mirrors tag).**
+  `findByAliasIgnoreCase` (`Optional`) is replaced by `findByAlias` (exact) → `findAllByAliasIgnoreCase`
+  (plural, lowest id) → the existing create-when-absent branch (INSTITUTION/GROUP and the
+  maiden-name alias are preserved verbatim). There is no human in the importer loop and the path
+  creates-on-absent anyway, so a deterministic guess is the right behaviour — exactly like tags.
+
+- **Name/sender path — `PersonService.findByName` — bail to null on ambiguity (the new wrinkle).**
+  Used only by `DocumentService.storeDocument` to resolve the upload **sender** from the parsed
+  filename. `findByFirstNameIgnoreCaseAndLastNameIgnoreCase` (`Optional`) is replaced by
+  `findByFirstNameAndLastName` (exact) → `findAllByFirstNameIgnoreCaseAndLastNameIgnoreCase`
+  (plural). Resolution returns the exact-case match, else the single case-insensitive match, else
+  — on **two or more** matches — **empty**. The sender is left unset rather than guessing.
+
+  **Why this diverges from the alias (and tag) decision:** the archive's value is correct
+  provenance. A confidently-wrong pre-filled `Hans Müller` is worse than an empty field, because a
+  senior reviewer will not re-check a value that is already filled in, whereas an empty sender
+  routes the document into the "needs completion" state (`metadataComplete=false`) for a human to
+  assign. The load-bearing comment at `findByName` records this so a future "consistency cleanup"
+  does not reintroduce the confidently-wrong-sender bug by switching it to lowest-id.
+
+- **Fail-closed on a null first name.** A parsed filename can lack a first name. The two new name
+  methods use explicit HQL equality (`= :firstName`) rather than a derived
+  `…IgnoreCase` query, because Spring Data folds a null derived-query argument to `first_name IS
+  NULL` — which would silently widen the match and pull a last-name-only / institution row in as a
+  "sender" (a quiet provenance-integrity defect). With HQL equality a null binds as `= NULL`,
+  which never matches, so a null first name resolves to **no sender**. This is pinned by a
+  real-Postgres repository test.
+
+- **Scope — "ambiguous" is case-insensitive only.** Both exact-case lookups (`findByAlias`,
+  `findByFirstNameAndLastName`) return `Optional`, so two **byte-identical same-case** rows would
+  still throw `NonUniqueResultException`. That is a true data anomaly, deliberately out of scope
+  (it is not a case-collision), and it surfaces as the opaque `INTERNAL_ERROR` — never a silently
+  wrong row — so it is no worse than any other unexpected error and needs no extra handling here.
+
+- **Same stance as tags otherwise:** no `unique(lower(alias))` / `unique(lower(name))` constraint
+  (collisions are valid human labels; `source_ref` is the stable identity per ADR-025), no
+  merge/dedupe, code-only and reversible, and no shared `resolveExactThenCi(...)` helper — the
+  two Person paths have different fallbacks, so the exact→CI→fallback logic is inlined at each
+  with its load-bearing comment (KISS).
+
+## Alternatives considered
+
+- **A `unique(lower(name))` index** — rejected: the collisions are valid canonical nodes, and
+  the migration would fail against the existing data and block startup.
+- **Merging/deduping the colliding tags** — rejected: each has a distinct `source_ref`, tree
+  position, and real document attachments; they are not duplicates.
+- **Round-tripping tag IDs instead of names** so resolution can't be ambiguous at all — the
+  cleaner long-term shape (removes the name-as-key smell), but a larger change with frontend
+  surface; deferred to #732. The lookup fix here is the minimal correct unblock.
+- **Hoisting resolution into `DocumentService.resolveTags`** — rejected: it would duplicate the
+  rule across the edit, bulk-edit, and import paths and let them drift; `findOrCreate` stays
+  the one owner.

+# ADR-034 — Remove NL/smart-search (supersedes ADR-028 ×2, ADR-034-ollama, ADR-035)
+
+**Date:** 2026-06-07
+**Status:** Accepted
+**Issue:** #772
+**Supersedes:** ADR-028 (nl-search-ollama), ADR-028 (ollama-docker-compose-service), ADR-034 (ollama-production-deployment-and-keep-alive), ADR-035 (rule-based-nlp-service)
+
+---
+
+## Context
+
+The natural-language search feature ("KI-Suche" / smart search) allowed users to enter
+free-form queries like *"Was hat Walter an Emma im Krieg geschrieben?"* and have them
+interpreted by an LLM into structured filters (persons, tags, date range, keywords).
+
+The feature went through two major iterations:
+1. **Ollama integration** (ADR-028): an `ollama` Docker service running a local LLM
+   (llama3.2/gemma3) parsed queries via a JSON-mode prompt.
+2. **Rule-based NLP service** (ADR-035): after Ollama proved too slow and unreliable on
+   CPU-only hardware, a Python FastAPI microservice (`nlp-service`, port 8001) replaced
+   it with deterministic regex + spaCy parsing plus a lightweight LLM call.
+
+Both approaches shared the same fundamental problem: inference on the production server
+(Hetzner Serverbörse, no GPU, 64 GB RAM, i7-6700) was too slow to be useful, with
+typical query latencies of 10–30 seconds. Users got better and faster results from
+the existing keyword search with date/person/tag filters.
+
+## Decision
+
+**Remove the NL search feature entirely.** The Python `nlp-service` microservice, the
+Spring Boot `search/` package (`NlSearchController`, `NlQueryParserService`,
+`RestClientNlpClient`, `NlSearchRateLimiter`, and all supporting classes), the frontend
+NL search components (`SmartModeToggle`, `SmartSearchStatus`, `InterpretationChipRow`,
+`DisambiguationPicker`), the related Docker Compose services, Prometheus scrape job,
+Grafana dashboard, and all i18n keys are removed.
+
+The existing structured search (FTS keyword + person/tag/date/directional filters) is
+sufficient for the archive's current audience and search workload.
+
+## Consequences
+
+- **Capability removed:** users can no longer enter free-form natural-language queries.
+  They must use the structured filter bar (keyword text box + person/tag/date/directional
+  dropdowns). For documents where these filters are sufficient, there is no regression.
+- **Operational simplification:** the Docker Compose stack loses two services
+  (`nlp-service` and previously `ollama`/`ollama-model-init`). Memory budget on the
+  production host is freed. No external model weights need to be kept warm.
+- **Future reinstatement:** if a GPU-capable host becomes available, re-implementing
+  server-side LLM inference would be straightforward given the clean separation of the
+  `NlSearchController` entry point. However, this ADR deliberately avoids leaving dead
+  infrastructure or stub code in place — start clean if and when that becomes viable.
+- **No data or schema change:** only query/endpoint code and Docker services are removed.
+  The `documents`, `persons`, and `tags` tables and their FTS indexes are untouched.

 Alpine is used instead of Ubuntu: ~5 MB vs ~70 MB, and the digest is pinned to a specific sha256 so any upstream change requires an explicit Renovate bump PR. `util-linux` (which ships `nsenter`) is not part of the Alpine base image but is installed at run time in ~1 s from the warm VPS cache.
 
+This exact step now lives in the `reload-caddy` composite action (see [Composite actions](#composite-actions) below); both deploy workflows call it via `uses: ./.gitea/actions/reload-caddy`.

+## Composite actions
+
+The `nightly.yml` (staging) and `release.yml` (production) deploy workflows share their observability-stack deploy, Caddy reload, and smoke-test logic through three single-responsibility composite actions under `.gitea/actions/` (ADR-029). Before this, the shared logic was duplicated in both workflows and held together by `# Keep in sync with nightly.yml` comments — an unenforced honour-system invariant.
+
+| Action | Inputs | Purpose |
+|---|---|---|
+| `deploy-obs` | `grafana_admin_password`, `grafana_db_password`, `glitchtip_secret_key`, `postgres_password`, `postgres_host` | Deploy obs configs + secrets to `/opt/familienarchiv`, validate the compose config, start the stack, assert the five healthchecked services |
+| `reload-caddy` | — | Reload host Caddy via the privileged-sibling + nsenter pattern |
+| `smoke-test` | `host` | Verify the public surface (login reachable, HSTS pinned, Permissions-Policy present, `/actuator → 404`) |
+
+A workflow calls them by relative path, passing per-environment values as `with:` inputs:
+
+```yaml
+- uses: ./.gitea/actions/deploy-obs
+  with:
+    grafana_admin_password: ${{ secrets.GRAFANA_ADMIN_PASSWORD }}
+    grafana_db_password: ${{ secrets.GRAFANA_DB_PASSWORD }}
+    glitchtip_secret_key: ${{ secrets.GLITCHTIP_SECRET_KEY }}
+    postgres_password: ${{ secrets.STAGING_POSTGRES_PASSWORD }}
+    postgres_host: archiv-staging-db-1
+- uses: ./.gitea/actions/reload-caddy
+- uses: ./.gitea/actions/smoke-test
+  with:
+    host: staging.raddatz.cloud
+```
+
+### Checkout-first ordering rule
+
+A local composite action (`uses: ./…`) only exists on disk **after** the repo is checked out. `actions/checkout@v4` MUST therefore be the **first step** of any job that calls one — if a future reorder moves checkout later, every `uses: ./.gitea/actions/…` call fails because the action file is not yet on disk. Both deploy workflows pin checkout as step 1 for exactly this reason.
+
+### Secrets inside composite actions
+
+The `secrets.*` context is **not** available inside a composite action. Secrets are passed in as `inputs`, mapped to an `env:` block, and referenced as `$VAR`:
+
+```yaml
+inputs:
+  grafana_admin_password:
+    required: true        # no default — a missing secret must fail loudly, never fall back to empty
+runs:
+  using: composite
+  steps:
+    - shell: bash         # composite steps do NOT default the shell — always declare it
+      env:
+        GRAFANA_ADMIN_PASSWORD: ${{ inputs.grafana_admin_password }}
+      run: |
+        cat > obs-secrets.env <<EOF   # unquoted EOF — $VAR expands at the shell layer
+        GRAFANA_ADMIN_PASSWORD=$GRAFANA_ADMIN_PASSWORD
+        EOF
+```
+
+Two load-bearing details:
+
+- **Unquoted heredoc delimiter (`<<EOF`, not `<<'EOF'`).** With a quoted delimiter the shell writes the literal string `$GRAFANA_ADMIN_PASSWORD`, and `docker compose config --quiet` still passes (the variable is *present, just wrong*). The `deploy-obs` action guards against this with a five-key **non-empty** check (`grep -Eq "^KEY=.+"`) immediately after writing `obs-secrets.env`. `chmod 600` is the action's final operation so the file is never world-readable.
+- **Every `run:` step declares `shell: bash`.** Composite actions do not inherit the workflow's default shell; a step without it fails to run.
+
+### Adding an input to an action
+
+To thread a new per-environment value (e.g. a new secret) through `deploy-obs`:
+
+1. Add it under `inputs:` in `.gitea/actions/deploy-obs/action.yml` with `required: true` and **no `default:`**.
+2. Map it in the relevant step's `env:` block: `NEW_KEY: ${{ inputs.new_key }}`.
+3. Reference it as `$NEW_KEY` in the `run:` script — add a `NEW_KEY=$NEW_KEY` line to the heredoc **and** a matching entry to the five-key guard loop.
+4. Pass it from **both** workflows' `with:` blocks. That is the whole point of the action: the contract lives in one place, so neither environment can silently drift.

-- OCR throughput needs scaling beyond a single-node Surya/Kraken setup
-- Real user load profiled in Grafana shows response-time degradation

Das Split-Layout (70/30) bleibt erhalten: links die Briefliste, rechts die Sidebar mit Personen und Status.</p>
+    <p class="prose">Die linke Fläche zeigt: oben einen optionalen Einleitungs-Textarea (<code>body</code>), darunter die geordnete Itemliste, ganz unten eine Aktionsleiste mit „+ Brief hinzufügen" und „+ Zwischentext hinzufügen". Jedes Item hat einen Drag-Handle, eine Positionsnummer, den Inhalt und einen Entfernen-Button.</p>
+    <p class="prose">Dokument-Items zeigen Titel und Kurz-Metadaten. Eine „Notiz hinzufügen/bearbeiten"-Aktion expandiert ein Textarea direkt unterhalb des Items — kein Modal, kein separates Formular. Interlude-Items (reiner Zwischentext) zeigen direkt ein editierbares Textarea mit orangenem Hintergrund zur klaren visuellen Unterscheidung.</p>
+    <p class="prose">Speicheraktionen: Speichern (bei veröffentlichter Journey) oder „Entwurf speichern" + „Veröffentlichen" (bei DRAFT). Die Savebarlogik ist identisch zum GeschichteEditor. Alle Mutationen lösen sofort einen API-Call aus und aktualisieren den lokalen Zustand optimistisch — kein separates Save für einzelne Items.</p>

+    <h2>Implementation Guide — Journey-Editor</h2>
+
+    <h3>Neue Komponente</h3>
+    <table>
+      <thead><tr><th>Datei</th><th>Typ</th><th>Beschreibung</th></tr></thead>
+      <tbody>
+        <tr><td><code>src/lib/geschichte/JourneyEditor.svelte</code></td><td>Svelte-Komponente</td><td>Hauptkomponente; Props: <code>geschichte: Geschichte</code></td></tr>
+        <tr><td><code>src/lib/geschichte/JourneyItemRow.svelte</code></td><td>Svelte-Komponente</td><td>Eine Zeile (Dokument oder Interlude); Props: <code>item: JourneyItem, position: number</code>, Events: <code>remove, noteChange</code></td></tr>
+      </tbody>
+    </table>
+
+    <h3>Edit-Page-Integration</h3>
+    <ul>
+      <li><code>GeschichteEditor.svelte</code> erhält ein neues Prop <code>type: GeschichteType</code>.</li>
+      <li>Wenn <code>type === 'JOURNEY'</code>: rendere <code>JourneyEditor</code> statt TipTap-Editor. Die Sidebar (Personen, Status, Savebar) bleibt identisch.</li>
+      <li>Die Savebar-Logik ist in der Edit-Page (<code>+page.svelte</code>) verankert — <code>JourneyEditor</code> gibt nur Änderungen nach oben (Svelte-Events oder bindable Props), die Seite hält den Save-State.</li>
+    </ul>
+
+    <h3>API-Calls</h3>
+    <table>
+      <thead><tr><th>Aktion</th><th>Endpoint</th><th>Body</th></tr></thead>
+      <tbody>
+        <tr><td>Brief hinzufügen</td><td><code>POST /api/geschichten/{id}/items</code></td><td><code>{documentId: UUID}</code></td></tr>
+        <tr><td>Zwischentext hinzufügen</td><td><code>POST /api/geschichten/{id}/items</code></td><td><code>{note: string}</code></td></tr>
+        <tr><td>Notiz speichern/bearbeiten</td><td><code>PATCH /api/geschichten/{id}/items/{itemId}</code></td><td><code>{note: string | null}</code></td></tr>
+        <tr><td>Item entfernen</td><td><code>DELETE /api/geschichten/{id}/items/{itemId}</code></td><td>—</td></tr>
+        <tr><td>Reihenfolge speichern</td><td><code>PUT /api/geschichten/{id}/items/reorder</code></td><td><code>[{id: UUID, position: number}]</code></td></tr>
+      </tbody>
+    </table>
+
+    <h3>Optimistische Updates</h3>
+    <ul>
+      <li>Alle Mutationen (add, remove, reorder, noteChange) aktualisieren den lokalen State <em>sofort</em>, der API-Call läuft parallel.</li>
+      <li>Bei Fehler: lokalen State zurückrollen und einen <code>aria-live="polite"</code>-Fehlerhinweis anzeigen.</li>
+      <li>Notiz-Saving ist ein Sonderfall: es gibt kein optimistisches Update da der Wert bereits live im Textarea ist — nur blur → PATCH.</li>
+    </ul>
+
+    <h3>DocumentPicker-Integration</h3>
+    <ul>
+      <li>Der „Brief hinzufügen"-Button öffnet die bestehende <code>DocumentPicker</code>-Komponente (prüfe <code>$lib/document/</code> auf vorhandene Typeahead-Komponenten).</li>
+      <li>Nach Auswahl eines Dokuments: <code>POST /items</code> mit <code>documentId</code>, neues Item wird an das Ende der Liste angehängt und eingeblendet.</li>
+      <li>Bereits in der Journey enthaltene Dokumente: in der Picker-Ergebnisliste mit einem „Bereits enthalten"-Hinweis markieren und deaktivieren.</li>
+    </ul>
+
+    <h3>Drag-to-Reorder</h3>
+    <ul>
+      <li>Bibliothek: prüfe zunächst ob <code>@dnd-kit/core</code> oder <code>svelte-dnd-action</code> bereits im <code>package.json</code> ist. Kein neues Package einführen ohne Absprache.</li>
+      <li>Nach dem Drop: neue Reihenfolge als Array <code>[{id, position}]</code> berechnen (position = index * 10 lässt Lücken für künftige Inserts) und <code>PUT /items/reorder</code> senden.</li>
+      <li>Keyboard-Drag: Space/Enter startet, Arrow Up/Down verschiebt, Space/Enter bestätigt, Escape abbricht. Screenreader-Announcement: „Eintrag X von Position Y nach Z verschoben".</li>
+    </ul>
+
+    <h3>Barrierefreiheit</h3>
+    <ul>
+      <li>Items-Liste: <code>&lt;ol&gt;</code>-Element — kommuniziert die Ordnung an Screenreader.</li>
+      <li>Drag-Handle: <code>role="button"</code>, <code>tabindex="0"</code>, <code>aria-label="Reihenfolge von '{title}' ändern"</code>.</li>
+      <li>Entfernen-Button: <code>aria-label="'{title}' entfernen"</code>; kein reines ×-Zeichen ohne Label.</li>
+      <li>Notiz-Textarea: <code>aria-label="Kuratoren-Notiz für '{title}'"</code>.</li>
+      <li>Touch-Targets: alle interaktiven Elemente min 44×44px (WCAG 2.2 AA).</li>
+      <li>Fokusring: <code>focus-visible:ring-2 focus-visible:ring-primary</code> auf allen Buttons und Textareas.</li>
+    </ul>
+
+    <h3>Abgrenzung zu GeschichteEditor</h3>
+    <ul>
+      <li>TipTap wird für JOURNEY <em>nicht</em> geladen — kein unnötiger Bundle-Load.</li>
+      <li>Die Sidebar (Personen, Status) ist für beide Typen identisch — kein Duplikat, die Sidebar-Komponente wird geteilt.</li>
+      <li>Savebar-Logik (DRAFT/PUBLISHED/Retract) ist identisch — JourneyEditor ändert sie nicht.</li>
+      <li><code>Geschichte.body</code> dient für JOURNEY als Einleitungstext (Plaintext, kein HTML). Kein Rich-Text-Rendering auf der Leseseite nötig.</li>
+    </ul>
+  </div>

+    <div class="section-title">Konzept</div>
+    <p class="prose">Eine <em>Lesereise</em> ist eine <code>Geschichte</code> mit <code>type === 'JOURNEY'</code>. Ihr Kerninhalt ist eine geordnete Sequenz von Briefen (<code>JourneyItem</code>s mit <code>document_id</code>) und Zwischentexten (<code>JourneyItem</code>s ohne <code>document_id</code>). Das optionale Feld <code>body</code> dient als Einleitung/Preface.</p>
+    <p class="prose">Diese Spec deckt drei Änderungen ab: (1) die Typauswahl auf <code>/geschichten/new</code> als vorgelagerter Schritt, (2) das „REISE"-Badge in der Übersichtsliste, und (3) die neue Journey-Leseansicht auf der Detailseite, die den bestehenden Prosa-Body durch eine nummerierte Briefliste ersetzt.</p>
+    <p class="prose">Dokument-Items zeigen Titel, Datum, Sender→Empfänger und einen Link zum Brief. Optionale Kuratoren-Notizen erscheinen als Annotation mit Mint-Linker-Rand unter dem Briefeintrag. Interlude-Items (kein Dokument) erscheinen als eingerückte Absätze mit orangenem linken Rand — klar vom Dokumenttyp unterscheidbar, aber harmonisch im Lesefluss.</p>

+
+    <h3>Neue Komponenten</h3>
+    <ul>
+      <li><code>JourneyReader.svelte</code> — rendert Intro + Items-Liste; Props: <code>geschichte: GeschichteDetail</code></li>
+      <li><code>JourneyItemCard.svelte</code> — ein Dokument-Item mit optionaler Annotation; Props: <code>item: JourneyItem, position: number</code></li>
+      <li><code>JourneyInterlude.svelte</code> — ein reiner Text-Interlude; Props: <code>note: string</code></li>
+    </ul>
+
+    <h3>Datenmodell (nach #750)</h3>
+    <ul>
+      <li><code>GeschichteType: 'STORY' | 'JOURNEY'</code></li>
+      <li><code>JourneyItem: { id: UUID, position: number, document: DocumentSummary | null, note: string | null }</code></li>
+      <li><code>Geschichte.items</code> — geordnete Liste (nach <code>position</code> ASC); für STORY leer</li>
+      <li><code>Geschichte.body</code> — für JOURNEY der optionale Einleitungstext (plaintext, kein HTML); für STORY der Rich-Text-Body</li>
+    </ul>
+
+    <h3>Typauswahl — Implementierungshinweise</h3>
+    <ul>
+      <li>Die Typauswahl ist ein Schritt INNERHALB der <code>/geschichten/new</code>-Route — kein eigener URL, kein <code>goto()</code>. Zustand <code>let selectedType: GeschichteType | null = null</code> in der Komponente.</li>
+      <li>Erst wenn <code>selectedType !== null</code> ist der „Weiter"-Button aktiviert (<code>disabled={!selectedType}</code>).</li>
+      <li>Nach Klick auf „Weiter": wenn <code>selectedType === 'JOURNEY'</code> → <code>goto('/geschichten/new?type=JOURNEY')</code> und zeige den Journey-Editor (aus Issue #753); wenn <code>STORY</code> → bestehender GeschichteEditor (unverändert).</li>
+      <li>Die Karten verwenden <code>role="radio"</code> und <code>aria-checked</code> für Accessibility. Keyboard: Arrow-Keys wechseln zwischen den Karten, Space/Enter wählt aus.</li>
+    </ul>
+
+    <h3>Journey-Badge — Implementierungshinweise</h3>
+    <ul>
+      <li>Badge nur in <code>GeschichtenCard.svelte</code> hinzufügen — keine Änderung an der Listenlogik oder dem API-Aufruf.</li>
+      <li>Text: „REISE" (Kurzform für die Metaspalte); <code>aria-label="Lesereise"</code> für den Badge-Span.</li>
+    </ul>
+
+    <h3>Journey-Reader — Implementierungshinweise</h3>
+    <ul>
+      <li>Items werden bereits geordnet vom Backend geliefert (<code>ORDER BY position ASC</code>). Keine client-seitige Sortierung nötig.</li>
+      <li>Ein Item ist Interlude wenn <code>item.document === null</code>. In diesem Fall: <code>JourneyInterlude</code>-Komponente rendern.</li>
+      <li>Der Intro-Absatz (<code>body</code>) wird als Plaintext gerendert — <em>nicht</em> als innerHTML. Im Editor wird es als einfaches Textarea gespeichert, kein HTML.</li>
+    </ul>
+
+    <h3>Berechtigungen</h3>
+    <ul>
+      <li>„Bearbeiten" und „Löschen" nur für <code>currentUser.permissions.includes('BLOG_WRITE')</code> — gleich wie Story.</li>
+      <li>Auf Mobile: Bearbeiten/Löschen im BottomSheet hinter ··· — gleich wie Story.</li>
+    </ul>
+
+    <h3>Barrierefreiheit</h3>
+    <ul>
+      <li>Items-Liste: <code>&lt;ol&gt;</code> semantisch für die geordnete Briefliste. Interludes sind <code>&lt;li&gt;</code>-Elemente mit <code>aria-label="Kuratorennotiz"</code>.</li>
+      <li>„Brief öffnen"-Link: beschreibender Text mit Briefdatum im <code>aria-label</code>, z.B. <code>aria-label="Brief vom 12. Juli 1938 öffnen"</code>.</li>
+      <li>Touch-Targets: jede Dokumentkarte hat mindestens 44px Höhe durch den Padding der Karte.</li>
+      <li>Fokusring: <code>focus-visible:ring-2 focus-visible:ring-primary</code> auf allen Links.</li>
+    </ul>

+  <h2>4 · Quick-Action im Dokument-Detail — wo sie lebt</h2>
+  <p>Die Dokument-Detailseite ist ein <b>vollflächiger Viewer ohne Sidebar</b> (<code>fixed inset</code>). Aktions-Flächen gibt es nur zwei: die <code>DocumentTopBar</code> und den aufklappbaren <b>Details-Drawer</b>. Die Quick-Action lebt an beiden — primär als <b>„Zeitstrahl"-Spalte im Drawer</b> (spiegelt die Geschichten-Spalte), plus ein <b>Top-Bar-Button</b> für den Ein-Klick-Weg.</p>
+</div>
+
+<div class="callout navy"><strong>Warum der Details-Drawer der richtige Ort ist:</strong> Er zeigt heute schon, <i>wozu ein Brief gehört</i> — Personen, Schlagwörter und <b>Geschichten</b> (mit „Zuordnen"-Aktion, gegated über <code>canBlogWrite</code>, <code>DocumentMetadataDrawer.svelte:210</code>). Zeitstrahl-Ereignisse sind strukturell identisch („dieser Brief gehört zu diesen Ereignissen") und bekommen daher eine gleichwertige vierte/fünfte Spalte. Konsistent &amp; auffindbar dort, wo Nutzer ohnehin „Zugehörigkeit" suchen.</div>

+# Family Timeline (Zeitstrahl) — Design Spec
+
+**Date:** 2026-06-07
+**Status:** Approved — pending implementation plan
+
+## Problem
+
+The archive can capture, transcribe, organize, and browse letters, but the transcribed material does not yet add up to a *story in time*. Readers (younger, phone-first) have no way to feel the family's history unfold; transcribers don't see their work become something larger. A previous attempt to derive meaning automatically (LLM search) was slow and low-quality, so the family is wary of auto-extraction from handwriting.
+
+## Goal
+
+A **hand-curated, year-banded vertical timeline** — the "Zeitstrahl" — that weaves three layers into one chronological view:
+
+1. **Person life-events** derived from already-curated structured data (`Person` birth/death dates, marriage years from `PersonRelationship.fromYear`). Trusted, free, no extra entry. (Requires the Person birth/death fields to move from year-integers to date + precision — see foundational issue 1.)
+2. **Hand-curated events** the family writes — both **personal** (a move, an illness, emigration) and **historical** (a war, hyperinflation). Editorially controlled, always correct.
+3. **Letters**, auto-placed by their existing `documentDate`, optionally hand-linked to an event to cluster them.
+
+Two surfaces, one component:
+- **Global timeline** at `/zeitstrahl`.
+- **Per-person "Lebensweg"** — the same view filtered to one person, embedded on the Person detail page.
+
+Built for phones (vertical scroll), honest about date precision, with no fabricated dates.
+
+### Non-goals (YAGNI)
+
+- ❌ Auto-extracting events from transcription text — explicitly avoided; this is what makes the feature trustworthy.
+- ❌ Importing an external historical-events dataset — historical events are hand-entered too.
+- ❌ A map / geographic view — that is a separate future feature (B2).
+- ❌ Per-derived-event hide/override toggle — deferred refinement; MVP shows all derived events.
+- ❌ Day-resolution timeline axis — the axis is the **year**; finer dates only affect within-band ordering and label text.
+
+## Core principle: the year is the axis
+
+Most dates in the archive are year-only (birth/death/marriage years are years by nature; many letters carry `YEAR`/`APPROX` precision). Therefore:
+
+- The timeline spine is a **sequence of year bands**. Everything for a given year lives in that band.
+- **Finer ordering only when we have it.** A `DAY`-precision letter (`1923-04-12`) sorts above a `YEAR`-precision one (`1923`) *within* the 1923 band; we never invent a day we don't have.
+- **An "Ohne Datum" bucket** at the end holds items with `UNKNOWN` precision.
+- **Honest precision rendering** reuses the existing `DatePrecision` enum for every dated item (events and letters share one rendering path).
+
+### Date rendering (shared by events and letters)
+
+| `DatePrecision` | German render | Example |
+|---|---|---|
+| `DAY` | full date | `28. Juli 1914` |
+| `MONTH` | month + year | `Juli 1914` |
+| `SEASON` | season + year | `Sommer 1914` |
+| `YEAR` | year only | `1914` |
+| `APPROX` | "ca." + year | `ca. 1914` |
+| `RANGE` | start–end year | `1914–1918` |
+| `UNKNOWN` | undated bucket | `Ohne Datum` |
+
+A `RANGE` item is shown in its **start year's band** with a span marker; it is not duplicated across every year it covers.
+
+## Data model
+
+A new `timeline/` domain package on the backend (kept deliberately separate from the in-flight Lesereisen/`Geschichte` work in #750–753).
+
+### `TimelineEvent` entity
+
+Mirrors the `Document` date model for consistency, so events and letters use one date-handling code path.
+
+| Field | Type | Notes |
+|---|---|---|
+| `id` | `UUID` | `@GeneratedValue(UUID)` |
+| `title` | `String` | required |
+| `type` | `EventType` enum | `PERSONAL`, `HISTORICAL` |
+| `eventDate` | `LocalDate` | required — most precise date known (WW1 → `1914-07-28`; vague year → `1920-01-01`) |
+| `precision` | `DatePrecision` | reuse existing enum; default `YEAR` — governs rendering & whether the day matters |
+| `eventDateEnd` | `LocalDate` (nullable) | only set when `precision == RANGE` |
+| `description` | `TEXT` (nullable) | free-text narrative for the event |
+| `persons` | ManyToMany `Person` | who the event involves; drives the per-person view & filtering |
+| `documents` | ManyToMany `Document` | optional hand-linked supporting letters (the "cluster letters to an event" feature) |
+| `createdBy` / `createdAt` / `updatedBy` / `updatedAt` / `version` | audit | standard entity conventions |
+
+- `@Schema(requiredMode = REQUIRED)` on every always-populated field (`id`, `title`, `type`, `eventDate`, `precision`).
+- Collections use `@Builder.Default new HashSet<>()`.
+- New Flyway migration adds `timeline_events`, `timeline_event_persons`, `timeline_event_documents` join tables.
+
+### `EventType` enum
+
+`PERSONAL` | `HISTORICAL`. Personal events render with a person/family accent; historical events with a "world" accent and muted styling so the two layers are visually separable.
+
+### Prerequisite: migrate `Person` birth/death to date + precision
+
+Today `Person` stores `birthYear`/`deathYear` as `Integer`, so a known exact birthday (e.g. `1901-03-14`) has nowhere to live and derived events are stuck at year precision. This is fixed by a **foundational Person-domain migration** that the timeline depends on (and which delivers value on its own — precise dates then render on person cards, hover cards, and the Stammbaum).
+
+**Change:** replace `birthYear`/`deathYear` (`Integer`) with:
+
+| Field | Type | Notes |
+|---|---|---|
+| `birthDate` | `LocalDate` (nullable) | most precise date known |
+| `birthDatePrecision` | `DatePrecision` (nullable) | `YEAR` for year-only, `DAY` for exact birthdays, etc. |
+| `deathDate` | `LocalDate` (nullable) | |
+| `deathDatePrecision` | `DatePrecision` (nullable) | |
+
+**Flyway data migration:** existing `birth_year` → `birth_date = '{year}-01-01'`, `birth_date_precision = 'YEAR'` (same for death); then drop the year columns.
+
+**Re-import preservation (ADR-025):** the canonical importer (`PersonRegisterImporter` / `tools/import-normalizer/persons_tree.py`) only carries the *year*. On re-import it must **not** clobber a hand-entered finer-than-`YEAR` date — if the existing precision is `DAY`/`MONTH`/`SEASON`, preserve it; only refresh from the spreadsheet year when the field is empty or still `YEAR`-from-import.
+
+**Bounding the blast radius:** `PersonNodeDTO` keeps exposing an `Integer birthYear`/`deathYear` *derived* from the new date (`birthDate.getYear()`), so the Stammbaum layout (`familyForest.ts` et al.) is untouched. Display surfaces (person card, hover card) move to a shared precision-aware formatter — extend the existing `frontend/src/lib/person/personLifeDates.ts`. The person edit/new forms gain date inputs with a precision selector.
+
+**Scope note:** `PersonRelationship.fromYear` (marriage year) stays `Integer`/`YEAR` for MVP — precise marriage dates are a later, parallel extension if wanted.
+
+### Derived person-events (not persisted)
+
+Assembled on read from the migrated `Person` data; never stored:
+
+| Source | Derived event | `eventDate` | precision |
+|---|---|---|---|
+| `Person.birthDate` | *Geburt: {name}* | `Person.birthDate` | `Person.birthDatePrecision` |
+| `Person.deathDate` | *Tod: {name}* | `Person.deathDate` | `Person.deathDatePrecision` |
+| `PersonRelationship` `SPOUSE_OF.fromYear` | *Heirat: {A} & {B}* | `{fromYear}-01-01` | `YEAR` |
+
+Emitted in the same DTO shape as a curated event, flagged `derived: true`, `type = PERSONAL`. They cannot be edited from the timeline (they are edited at their source: Person record / relationship). A marriage is derived once per `SPOUSE_OF` edge (symmetric edges are stored once — see existing relationship rules).
+
+### Letters
+
+Placed by `Document.documentDate`:
+- Band = `documentDate.getYear()`; `UNKNOWN` precision → "Ohne Datum" bucket.
+- Sub-ordered within a band by full date when precision allows.
+- A letter may also appear under an event it's linked to (via `TimelineEvent.documents`) as a cluster, in addition to its own band placement.
+
+## Assembly & API
+
+A `TimelineService` merges the three layers into a year-bucketed DTO for the requested scope and filters. Layering rules apply: the service owns `TimelineEventRepository` and reaches Person/Document/Relationship data through their **services**, never their repositories.
+
+### DTOs
+
+- `TimelineEntryDTO` — one renderable item: `kind` (`EVENT` | `LETTER`), `eventDate`, `precision`, `eventDateEnd`, `title`, `type` (for events), `derived` flag, plus the source id (eventId / documentId) and minimal display fields (sender/receiver names for letters, linked person ids for events).
+- `TimelineYearDTO` — `{ year: int, entries: TimelineEntryDTO[] }`.
+- `TimelineDTO` — `{ years: TimelineYearDTO[], undated: TimelineEntryDTO[] }`.
+
+### Endpoints
+
+- `GET /api/timeline` — global timeline. Query params (all optional): `personId`, `generation`, `type` (`PERSONAL`/`HISTORICAL`), `fromYear`, `toYear`. The per-person "Lebensweg" is just `GET /api/timeline?personId=…` — no separate endpoint. Requires `READ_ALL`.
+- `POST /api/timeline/events` — create a curated event. `@RequirePermission(Permission.WRITE_ALL)`.
+- `PUT /api/timeline/events/{id}` — update. `@RequirePermission(Permission.WRITE_ALL)`.
+- `DELETE /api/timeline/events/{id}` — delete. `@RequirePermission(Permission.WRITE_ALL)`.
+- `GET /api/timeline/events/{id}` — fetch a single event for the edit form. Requires `READ_ALL`.
+
+Input DTO `TimelineEventRequest` lives flat in the `timeline/` package. Errors use `DomainException.notFound/...`; **no new `ErrorCode`** is required. Run `npm run generate:api` after backend model/endpoint changes.
+
+## Frontend
+
+- New domain dir `frontend/src/lib/timeline/`:
+  - `TimelineView.svelte` — orchestrator; accepts an optional `personId` prop so the same component powers both global and per-person views.
+  - `YearBand.svelte` — one year section header + its entries.
+  - `EventCard.svelte` — renders a `PERSONAL`/`HISTORICAL`/derived event with precision-aware date label.
+  - `LetterCard.svelte` — compact letter row (sender → receiver, snippet/title, date), links to `/documents/[id]`.
+  - `TimelineFilters.svelte` — person, generation, layer toggles, year range.
+  - `dateLabel.ts` — the shared precision→label helper (reuse/extend `lib/document/timeline.ts` helpers like `formatTickLabel` where they fit).
+- Routes:
+  - `/zeitstrahl` — global timeline (`+page.server.ts` loads `/api/timeline`).
+  - `/zeitstrahl/events/new` and `/zeitstrahl/events/[id]/edit` — curator forms, gated to `WRITE_ALL`, using the form-actions pattern.
+- Person detail page gains a **Lebensweg** card section embedding `<TimelineView personId={person.id} />`.
+- Styling per project conventions (card pattern, brand tokens, `font-serif` for names/titles, `BackButton`, mobile-first at 375px, dark-mode tokens).
+- i18n keys added to `messages/{de,en,es}.json` (German primary).
+
+## Testing
+
+- Backend: `TimelineService` assembly/merge/sort/precision-bucketing (unit + `@DataJpaTest` against Postgres via Testcontainers); controller permission gating; derived-event assembly (birth/death/marriage, symmetric marriage dedup).
+- Frontend: `dateLabel.ts` precision rendering; `TimelineView` global vs `personId` modes (`*.svelte.spec.ts`); filter behavior.
+- Follow project test discipline: targeted single-file runs locally only; full sweep left to CI.
+
+## Proposed issue breakdown (milestone "Zeitstrahl / Family Timeline")
+
+Ordered so each issue is independently shippable and reviewable; later issues depend on earlier ones. Issue 1 is a standalone Person-domain improvement and a hard prerequisite for the timeline's derived events.
+
+1. **Person birth/death → date + precision (foundational)** — replace `birthYear`/`deathYear` with `birthDate`/`deathDate` + precision on `Person`; Flyway data migration (year → `YYYY-01-01`, `YEAR`); update importer with re-import preservation rule; derive year in `PersonNodeDTO` (Stammbaum untouched); move person card / hover card to a precision-aware `personLifeDates.ts`; add date+precision inputs to person new/edit forms. Ships value on its own.
+2. **Backend: `TimelineEvent` entity + migration** — entity, `EventType`, Flyway migration + join tables, repository.
+3. **Backend: TimelineEvent CRUD API** — `TimelineEventController` + `TimelineService` write methods, `TimelineEventRequest` DTO, permission gating, `GET /events/{id}`.
+4. **Backend: derived person-events** — assemble Geburt/Tod/Heirat from migrated Person + relationship data via their services; unit-tested dedup.
+5. **Backend: timeline assembly endpoint** — `GET /api/timeline` merging events + derived events + letters into `TimelineDTO`; year-bucketing, precision sort, undated bucket, filters.
+6. **Frontend: shared date-label helper + types** — `dateLabel.ts`, regen API types.
+7. **Frontend: global `/zeitstrahl` view** — `TimelineView`, `YearBand`, `EventCard`, `LetterCard`, server load.
+8. **Frontend: filters** — `TimelineFilters` (person / generation / layer / year range).
+9. **Frontend: curator event forms** — `/zeitstrahl/events/new` + `/[id]/edit`, gated, with document & person pickers.
+10. **Frontend: per-person Lebensweg** — embed `<TimelineView personId>` on Person detail.
+11. **Polish & a11y** — mobile layout at 375px, dark mode, axe checks, i18n completeness (de/en/es).
+
+> An ADR may be warranted for the new `timeline/` domain + entity (per `docs/CLAUDE.md`, significant data-model change). Add as the next sequential ADR number when implementation starts.

+# spaCy NLP Service — Design Spec
+
+**Date:** 2026-06-07
+**Status:** Prototype
+
+## Problem
+
+The current NL search uses Ollama (`qwen2.5:7b-instruct-q4_K_M`) to parse free-text queries into structured extractions (person names, dates, role, keywords). Inference takes 5–15 seconds per query, making the feature too slow to be useful compared to filling in the filter UI manually.
+
+## Goal
+
+Build a standalone `nlp-service/` prototype that replaces Ollama with spaCy for query parsing. The prototype is scoped to **extraction quality evaluation** — run it locally, curl it with real archive queries, and measure whether spaCy extracts names/dates/keywords well enough to justify a full migration. No Java-side changes in this iteration.
+
+## Extraction Contract
+
+The service must produce an output compatible with the existing `OllamaExtraction` Java record:
+
+| Field | Type | Description |
+|---|---|---|
+| `personNames` | `string[]` | Names of persons mentioned, left-to-right order |
+| `personRole` | `"sender"` \| `"receiver"` \| `"any"` | Role of the person(s) in the document |
+| `dateFrom` | `string \| null` | ISO 8601 date `YYYY-MM-DD` or null |
+| `dateTo` | `string \| null` | ISO 8601 date `YYYY-MM-DD` or null |
+| `keywords` | `string[]` | Content words — fuzzy-matched against tags by Java |
+| `rawQuery` | `string` | Echo of the input query |
+
+**Two-person ordering:** `personNames` must be in left-to-right span order. Java maps `[0]` → sender, `[1]` → receiver.
+
+**`rawQuery` note:** In the current Java code `rawQuery` is set by the caller, not parsed from Ollama. The service echoes the input for convenience; the eventual `RestClientSpacyClient` will set it from the input directly, same as today.
+
+## Architecture
+
+```
+nlp-service/
+├── main.py        # FastAPI app — /parse and /health endpoints
+├── extractor.py   # NLP pipeline: NER → role → dates → keywords
+├── models.py      # Pydantic request/response types
+├── requirements.txt
+├── Dockerfile
+└── CLAUDE.md
+```
+
+Sits alongside `ocr-service/` in the repo. For the prototype it runs standalone (no docker-compose wiring).
+
+## Extraction Pipeline (`extractor.py`)
+
+Five steps run in sequence on each query.
+
+### Step 1 — NER pass
+
+Run spaCy on the query using the model for the requested language. Collect:
+- All `PER` spans → candidates for `personNames`
+- All `DATE` spans → raw text strings for step 3
+
+### Step 2 — Role detection
+
+Only relevant when exactly **one** PER entity is found. Walk the dependency tree of the PER span's root token; check if a governing `case` or `prep` token matches the sender or receiver preposition set for the language:
+
+| Language | Sender prepositions | Receiver prepositions |
+|---|---|---|
+| `de` | von, vom | an, nach, für |
+| `en` | from, by | to, for |
+| `es` | de, por | para, a |
+
+- One person + sender preposition → `personRole = "sender"`
+- One person + receiver preposition → `personRole = "receiver"`
+- One person + no match / two or more persons → `personRole = "any"`
+
+Two-person queries always return `"any"` — Java derives direction from position.
+
+### Step 3 — Date parsing
+
+For each DATE span, inspect the token immediately before the span to detect range direction:
+
+| Direction token | Effect |
+|---|---|
+| vor / before / antes de | Span → `dateTo` |
+| nach / after / después de | Span → `dateFrom` |
+| zwischen…und / between…and / entre…y | Earlier span → `dateFrom`, later → `dateTo` |
+| No direction token (bare year/date) | Span → both `dateFrom` and `dateTo` set to that year (year-range, Jan 1–Dec 31) |
+
+`dateparser.parse()` with `PREFER_DAY_OF_MONTH=first` converts the span text to a Python `date`. For `dateTo` results that resolve to a year boundary, set to Dec 31 of that year (mirrors `RestClientOllamaClient.parseDate()` behaviour).
+
+Output as ISO strings (`YYYY-MM-DD`) or `null`.
+
+### Step 4 — Keyword extraction
+
+Collect tokens that satisfy all of:
+- POS tag is `NOUN` or `PROPN`
+- Not a stopword
+- Not inside any NER span (PER or DATE)
+- Lemma length ≥ 3
+
+Output as lowercased lemmas. These are fuzzy-matched against the tags table by `NlQueryParserService.resolveTags()` on the Java side — no tag lookup in the Python service.
+
+Examples:
+- "Briefe aus dem Krieg" → `keywords: ["brief", "krieg"]`
+- "Texte über Weihnachten" → `keywords: ["text", "weihnachten"]`
+
+### Step 5 — Assembly
+
+```json
+{
+  "personNames": ["Opa Hermann", "Marie"],
+  "personRole": "any",
+  "dateFrom": null,
+  "dateTo": "1920-12-31",
+  "keywords": ["brief"],
+  "rawQuery": "Briefe von Opa Hermann an Marie vor 1920"
+}
+```
+
+## API
+
+### `POST /parse`
+
+**Request:**
+```json
+{ "query": "Briefe von Opa Hermann an Marie vor 1920", "lang": "de" }
+```
+
+`lang` is a required enum: `"de"` | `"en"` | `"es"`. Unknown values → HTTP 422 (FastAPI validation).
+
+**Response:** extraction object as above, HTTP 200.
+
+**Error:** pipeline crash → HTTP 500 `{"detail": "..."}`.
+
+### `GET /health`
+
+Returns HTTP 200 `{"status": "ok"}` when all three models are loaded.
+
+## Language Models
+
+| `lang` | spaCy model |
+|---|---|
+| `de` | `de_core_news_sm` |
+| `en` | `en_core_web_sm` |
+| `es` | `es_core_news_sm` |
+
+All three models are loaded at startup and held in memory. Routing is by the `lang` field on the request.
+
+## Dockerfile
+
+Mirrors `ocr-service/` — `python:3.11-slim`, non-root user, models baked into the image:
+
+```dockerfile
+FROM python:3.11-slim
+WORKDIR /app
+COPY requirements.txt .
+RUN pip install --no-cache-dir -r requirements.txt
+RUN python -m spacy download de_core_news_sm \
+ && python -m spacy download en_core_web_sm \
+ && python -m spacy download es_core_news_sm
+COPY . .
+RUN useradd --no-create-home --shell /usr/sbin/nologin --uid 1001 nlp \
+    && chown -R nlp:nlp /app
+USER nlp
+EXPOSE 8001
+CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "8001"]
+```
+
+Image size: ~350 MB. No volume needed — models live in the image layer.
+
+## Local Dev
+
+```bash
+cd nlp-service
+pip install -r requirements.txt
+python -m spacy download de_core_news_sm en_core_web_sm es_core_news_sm
+uvicorn main:app --reload --port 8001
+
+curl -X POST http://localhost:8001/parse \
+  -H "Content-Type: application/json" \
+  -d '{"query": "Briefe von Opa Hermann an Marie vor 1920", "lang": "de"}'
+```
+
+## Known Limitations
+
+- **Historical names:** spaCy models are trained on modern news corpora. Unusual 1899–1950 German names may not score as `PER`. Mitigation: the Java `resolveNames()` already does fuzzy matching against the persons table, so partial name extraction is recoverable.
+- **Role detection:** the preposition sets are a fixed enumeration (~12 tokens across 3 languages). Sentences that express direction without one of these prepositions will fall through to `personRole = "any"`. This is acceptable — `"any"` is the safe default and searches both sender and receiver positions.
+- **"über Oma" ambiguity:** if spaCy recognises "Oma" as a PER entity it lands in `personNames` (person search); if not, it lands in `keywords` (tag search via Java). Both paths return relevant results. The prototype evaluation will reveal which path dominates for real archive queries.
+
+## Out of Scope (prototype)
+
+- docker-compose integration (Ollama replacement)
+- Java-side changes (`RestClientSpacyClient`, rename `OllamaClient` → `NlParserClient`)
+- Tag lookup inside the Python service
+- Automated test suite (pytest fixtures) — evaluation is done by curling the running service

+// factory does NOT auto-resolve to an adjacent __mocks__ file the way Jest's
+// __mocks__/ does: for SvelteKit virtual modules, vitest substitutes some
+// exports (plain function refs like goto) but leaves others bound to the live
+// implementation (replaceState, which delegates through a getter). The result
+// is a partial mock that crashes when an unsubstituted export is hit.
+//
+// The sanctioned form keeps an INLINE sync factory:
+//   vi.mock('$app/forms', () => ({ enhance(node, submit) { ... } }));
+// (Sharing the body via a module imported into the factory is infeasible in
+// browser mode — vitest hoists vi.mock above the import; see ADR-012.)
+//
+// ESLint and the CI grep guard catch the pattern earlier; this in-suite test
+// catches it at every vitest invocation — the layer hardest to disable. It
