fix(docker): skip postinstall in production image

The production stage runs npm ci --omit=dev to install runtime deps for
the pre-built SvelteKit app. The postinstall script calls patch-package,
which is a devDependency, so it is absent and causes exit code 127.

--ignore-scripts is the correct npm-native fix: no lifecycle scripts are
needed when installing into a pre-built image.

+# ADR 012 — Browser-Mode Test Mocking Strategy
+
+**Status:** Accepted  
+**Date:** 2026-05-11 (revised 2026-05-12)  
+**Issues:** [#535 — original incident](https://git.raddatz.cloud/marcel/familienarchiv/issues/535) · [#553 — revision](https://git.raddatz.cloud/marcel/familienarchiv/issues/553)
+
+---
+
+## Context
+
+Vitest browser-mode tests (the `client` project, run with `@vitest/browser-playwright` / Chromium) use a different module resolution path than Node-environment tests. When a spec calls `vi.mock('some-module', factory)`, vitest registers a `ManualMockedModule`. At runtime, every time Chromium requests that module, a playwright route handler intercepts the request and calls the Node worker over **birpc** (`resolveManualMock`) to evaluate the factory and return the module body.
+
+This is safe for modules that are imported **statically** at spec module-eval time (e.g. `$app/navigation`, `$env/static/public`): those requests resolve before the first test runs and well before any teardown occurs.
+
+It is **unsafe** for modules that are imported **dynamically** (e.g. inside an `async onMount`, inside a lazy-loaded chunk): Chromium may fetch the module after the worker's birpc channel has already closed, producing:
+
+```
+Error: [birpc] rpc is closed, cannot call "resolveManualMock"
+  ❯ ManualMockedModule.factory   node_modules/@vitest/browser/dist/index.js:3221:34
+```
+
+This raises an unhandled rejection that exits the vitest process with code 1, even though every test in the run reported green.
+
+`pdfjs-dist` and `pdfjs-dist/build/pdf.worker.min.mjs?url` are loaded via `await Promise.all([import('pdfjs-dist'), import('pdfjs-dist/build/pdf.worker.min.mjs?url')])` inside `usePdfRenderer.svelte.ts::init()`, which is called from `onMount`. These dynamic imports triggered the race.
+
+---
+
+## Decision
+
+**Prefer prop injection over `vi.mock(module, factory)` for any module that is loaded dynamically in browser-mode specs.**
+
+### The libLoader pattern (for external rendering libraries)
+
+When a component depends on a large external library loaded via dynamic import, extract the import into an injectable loader function with a production default:
+
+```typescript
+// usePdfRenderer.svelte.ts
+type LibLoader = () => Promise<readonly [typeof import('pdfjs-dist'), { default: string }]>;
+
+const defaultLibLoader: LibLoader = () =>
+  Promise.all([import('pdfjs-dist'), import('pdfjs-dist/build/pdf.worker.min.mjs?url')]);
+
+export function createPdfRenderer(libLoader: LibLoader = defaultLibLoader) { ... }
+```
+
+The component threads the loader as an optional prop:
+
+```svelte
+<!-- PdfViewer.svelte -->
+let { url, ..., libLoader = undefined } = $props();
+const renderer = untrack(() => createPdfRenderer(libLoader));
+```
+
+Tests supply a synchronous fake — no `vi.mock` needed:
+
+```typescript
+const fakePdfjs = { GlobalWorkerOptions: ..., getDocument: vi.fn(), TextLayer: class {} };
+const fakeLoader = vi.fn().mockResolvedValue([fakePdfjs, { default: '' }] as const);
+render(PdfViewer, { url: '...', libLoader: fakeLoader });
+```
+
+### The test-host pattern (for component behaviour)
+
+For components that fetch data or call services, the `*.test-host.svelte` pattern threads the dependency as a prop rather than mocking the module. See `PersonMentionEditor.test-host.svelte` for the canonical example.
+
+---
+
+## Binding invariant: factory bodies must be synchronous (#553)
+
+The original revision of this ADR allowed `vi.mock(virtualModule, factory)` for SvelteKit/Vite virtual modules on the argument that their consumer imports were resolved at static-import time. **That reasoning is wrong.** What matters is what the **factory body** does, not where the mocked module is consumed.
+
+`EnrichmentBlock.svelte.spec.ts` (issue #553) was statically imported and still produced the race: its `vi.mock('$app/stores', async () => { const mod = await import(...); return mod; })` factory performed a dynamic import in its body, and that body was invoked asynchronously when Chromium fetched the manually-mocked module — sometimes after the worker's birpc channel had already closed.
+
+**Therefore: under `**/*.svelte.{test,spec}.ts`, every `vi.mock` factory body must be synchronous. No `await`, no `import(...)`.**
+
+If a factory needs to share state with the spec (a mutable ref, a `vi.fn`, a writable store), use `vi.hoisted()` to lift the reference above `vi.mock`'s implicit hoist:
+
+```ts
+const { mockNavigating } = vi.hoisted(() => ({
+    mockNavigating: { type: null as string | null }
+}));
+
+vi.mock('$app/state', () => ({
+    get navigating() {
+        return mockNavigating;
+    }
+}));
+```
+
+The getter defers the read until consumption time; `vi.hoisted` guarantees the reference is initialised before the (also hoisted) `vi.mock` factory runs. See `DropZone.svelte.spec.ts:9`, `NotificationBell.svelte.spec.ts:6-10`, and `EnrichmentBlock.svelte.spec.ts` for canonical examples.
+
+### Architectural follow-on: prefer `$app/state` over `$app/stores`
+
+`$app/stores` is the deprecated subscription-based store API; `$app/state` is the modern reactive proxy. New components should import from `$app/state`. 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.
+
+**Pattern note (#553):** Browser-mode tests run with `data-sveltekit-preload-data="off"` (set in `src/test-setup.ts` via the client project's `setupFiles`). Hover-prefetch otherwise fires real fetch requests for route loader chunks; those requests go through the same Playwright route handler that serves mocked modules. An in-flight prefetch landing after iframe teardown can hit the handler with a closed birpc channel, raising an unhandled rejection.
+
+---
+
+## Binding invariant: one canonical ID per mocked module (#553 — duplicate-id hazard)
+
+The sync-factory invariant above closes one named trigger of the `[birpc] rpc is closed` race. Investigation of a follow-up flake revealed a second, independent trigger: **the same resolved module URL mocked under two distinct ID strings** across or within spec files.
+
+`@vitest/browser-playwright` registers a Playwright `page.context().route(...)` handler per `vi.mock` call. The predicate matches on the module's resolved URL. When two `vi.mock` calls reference the same module under different IDs — for example `'$lib/foo.svelte'` and `'$lib/foo.svelte.js'` (both resolve to the same Svelte rune-module URL) — the registry stores both predicates but the cleanup map only tracks the latest. The orphan route survives session teardown. When the next session loads the same module, the orphan fires, calls `await module.resolve()` against a closed birpc channel, and crashes the run.
+
+This is fixed upstream in [vitest PR #10267](https://github.com/vitest-dev/vitest/pull/10267) (issue [#9957](https://github.com/vitest-dev/vitest/issues/9957)). Until that fix reaches a published `@vitest/browser-playwright` release, we close the gap from two sides:
+
+**The rule.** Every mocked module must be referenced under exactly one ID string across the entire client test suite. Pick the spelling production code uses. For Svelte 5 rune modules (`*.svelte.ts`), the canonical form is the no-extension import (`'$lib/foo.svelte'`) — matches the source file basename and matches Svelte 5 convention. Never mix `.svelte.js` and `.svelte` for the same module across specs.
+
+**Enforcement layers** (added in #553's second cycle, extending the four-layer chain above):
+
+5. **In-suite meta-test** at `frontend/src/__meta__/no-duplicate-mock-ids.test.ts` globs `src/**/*.svelte.{test,spec}.ts`, extracts every `vi.mock` first-arg string, canonicalises by stripping a trailing `.js`/`.ts` after `.svelte`, and fails if any canonical ID is referenced under two or more distinct spellings. Same shape as `no-async-mock-factories.test.ts`.
+6. **`patch-package` backport** of PR #10267 at `frontend/patches/@vitest+browser-playwright+4.1.0.patch`. Applied automatically by the `postinstall` hook. Closes the race at the route-handler level — even if a contributor reintroduces a duplicate-ID, the patched `register` handler unroutes the existing predicate before installing the new one.
+
+**When to remove the patch.** Once `@vitest/browser-playwright` ships a release containing PR #10267, delete `patches/@vitest+browser-playwright+4.1.0.patch`. Bump the dependency to the version containing the fix. The in-suite meta-test stays — it's a cheap permanent guard against the contributor-facing pattern, independent of upstream library version.
+
+---
+
+## Consequences
+
+- New browser-mode specs that need to stub an external library **must not** use `vi.mock(externalLib, factory)`. Add a loader/factory parameter to the underlying hook or service instead.
+- The CI `unit-tests` job includes a permanent grep guard that fails the build if `rpc is closed` appears in any coverage run log. This catches regressions before they reach the acceptance criterion.
+- Acceptance criterion for #535: 60 consecutive green `workflow_dispatch` CI runs against `main` after the fix is merged, with zero `rpc is closed` lines in any log.
+- **Enforcement (six layers, defence in depth):**
+  1. **ESLint `no-restricted-syntax`** in `eslint.config.js` (scoped to `**/*.{spec,test}.ts`) flags two patterns: (a) the literal `vi.mock('pdfjs-dist', ...)` — enforces the libLoader pattern — and (b) any `vi.mock(..., async () => { ... await import(...) ... })` — enforces the synchronous-factory invariant. Both messages point at this ADR. Failure surfaces at save time.
+  2. **CI grep guard** in `.gitea/workflows/ci.yml` runs before the test suite launches. Mirrors the ESLint patterns with `grep -Pzn`. ~10s round-trip.
+  3. **In-suite meta-test** at `frontend/src/__meta__/no-async-mock-factories.test.ts` globs `src/**/*.svelte.{test,spec}.ts` and asserts none match the banned pattern. Catches at every vitest invocation — the layer hardest to disable.
+  4. **CI birpc assert** runs after the coverage step and fails the build if `[birpc] rpc is closed` appears in any log line. Catches the symptom even if all the upstream layers were bypassed.
+  5. **In-suite duplicate-ID meta-test** at `frontend/src/__meta__/no-duplicate-mock-ids.test.ts` enforces the one-canonical-ID-per-module rule from the duplicate-id-hazard section above.
+  6. **`patch-package` backport** at `frontend/patches/@vitest+browser-playwright+4.1.0.patch` closes the upstream race itself, applied via `postinstall`. To be removed when `@vitest/browser-playwright` releases [vitest PR #10267](https://github.com/vitest-dev/vitest/pull/10267).
+- **Acceptance verification:** `coverage-flake-probe.yml` is a `workflow_dispatch`-triggered matrix workflow that runs the coverage suite 20× in parallel against a single SHA and asserts zero birpc lines. One fire, parallel cost, deterministic signal — replaces accumulating 20 sequential push events.
+- **When to revisit the LibLoader home:** If three or more components adopt this pattern, consider extracting a shared `$lib/types/lib-loader.ts` or a generic `DynamicImportLoader<T>` type to avoid parallel type definitions across modules.

+# ADR 013 — Client-Project Branch Coverage Threshold
+
+**Status:** Accepted  
+**Date:** 2026-05-14  
+**Issues:** [#556 — threshold drop](https://git.raddatz.cloud/marcel/familienarchiv/issues/556) · [#496 — long-tail-grind tracking](https://git.raddatz.cloud/marcel/familienarchiv/issues/496)
+
+---
+
+## Context
+
+The browser-mode component test suite (`vitest.client-coverage.config.ts`) enforces Istanbul coverage thresholds across `lines`, `functions`, `branches`, and `statements`. The `branches` metric was set to 80%, but the codebase sits at **75%** — below the gate — causing every CI run of `unit-tests` and `coverage-flake-probe` to fail on this check alone, even when all tests are green.
+
+**Measured baseline (2026-05-14, branch `feat/issue-553-birpc-async-mock-factory`, head `2e6cc346`):**
+
+```
+branches:   75%  (below the 80% gate — reason for this ADR)
+lines:      ≥ 80%
+functions:  ≥ 80%
+statements: ≥ 80%
+```
+
+Reproducer:
+
+```bash
+cd frontend && npm ci && npx vitest run -c vitest.client-coverage.config.ts --coverage
+```
+
+### The long-tail-grind problem
+
+In Istanbul's branch accounting, when a child component gains test coverage its branches are added to the parent's denominator. A child moving from 40% → 80% coverage can drag a parent from 78% → 72% because more branches in the call graph become reachable and must be covered. This is not a bug — it is how branch accounting works — but it means that on a large SvelteKit application the denominator grows with every coverage improvement, making an arbitrary 80% ceiling a constant grind. Per #496, the expected cost to reach 80% branches from 75% is 30–100+ commits with no guarantee of stability.
+
+### Why this layer is different
+
+The 80% branch floor used for backend unit/integration tests is appropriate for Java service code and permission logic. Browser-mode component coverage measures Svelte template branches: conditional class bindings, `{#if}` blocks, empty/loaded/error state guards. These branches have a fundamentally different accounting model and a higher inherent denominator. This ADR **only** lowers the browser-mode component gate; the backend test coverage gates are unaffected.
+
+### Security-relevant uncovered components
+
+The following auth/permission-boundary components currently have low or zero branch coverage. When ratchet-up work begins (see below), these are the highest-priority targets:
+
+- `src/routes/login/+page.svelte`
+- `src/routes/forgot-password/+page.svelte`
+- `src/routes/reset-password/+page.svelte`
+- `src/routes/register/+page.svelte`
+
+Note: the 75% figure already reflects the absence of coverage on these files. Lowering the gate does not create this gap — it makes the existing state legible.
+
+---
+
+## Decision
+
+Drop the `branches` threshold from `80` → `75` in `frontend/vitest.client-coverage.config.ts`. Leave `lines`, `functions`, and `statements` at `80`.
+
+The 75% figure matches the measured current state, allowing CI to pass while deliberate coverage improvement work (tracked in #496) continues without blocking other PRs. The asymmetry in the thresholds block is intentional and documented with an inline comment pointing here.
+
+---
+
+## Ratchet Rule
+
+The branches threshold ratchets **up by 3 percentage points** when the rolling 3-PR-average client-project branches figure on `main` stays at or above `threshold + 3pp` for ≥ 30 consecutive days. Direction is **up-only** — never lower the floor below 75 without a new ADR superseding this one. Manual today (verify before any `vitest.client-coverage.config.ts` edit); a future automation issue may codify the check.
+
+Concretely:
+- When `main` sustains ≥ 78% branches across 3 consecutive PRs for 30 days → raise gate to 78%
+- When `main` sustains ≥ 81% branches across 3 consecutive PRs for 30 days → raise gate back to 80%
+
+---
+
+## Non-goals
+
+- **Not** raising actual branch coverage — that is #496's job, tracked separately.
+- **Not** touching the server-project coverage configuration (`vitest.config.ts`) — only the client project hits the long-tail-grind pattern.
+- **Not** removing or relaxing any existing test files, `skipIf` guards, or axe-playwright accessibility runs.
+
+---
+
+## Consequences
+
+**Easier:**
+- CI unblocked — `unit-tests` and `coverage-flake-probe` jobs pass when all tests are green
+- The ratchet rule creates a concrete, observable path back to 80%
+
+**Harder:**
+- The gate now has near-zero headroom — any branch regression that drops below 75% will fail CI immediately
+- The 75% floor must not be treated as a permanent ceiling; the ratchet discipline requires active attention

+# ADR 014 — Pin actions/upload-artifact to v3 (Gitea act_runner v4 protocol incompatibility)

+**Status:** Accepted  
+**Date:** 2026-05-14  
+**Issues:** [#557 — re-regression](https://git.raddatz.cloud/marcel/familienarchiv/issues/557) · [#14 — original incident](https://git.raddatz.cloud/marcel/familienarchiv/issues/14)
+
+---
+
+## Context
+
+`actions/upload-artifact` is available in two incompatible major versions. The v4 client
+uploads via a GitHub-specific artifact API that is **not implemented** in Gitea's
+`act_runner` (the self-hosted CI substrate established by ADR-011). When a workflow step
+uses `actions/upload-artifact@v4` on this runner, `act_runner` returns a non-zero exit
+code from the v4 client even when all tests pass, producing:
+
+> green test suite — red job status — no artifact uploaded
+
+The failure lands in the upload step, _after_ the test output, making it hard to diagnose
+from the build log.
+

+The root cause of the re-regression was institutional-memory failure: the original
+rationale was captured only in a commit body, invisible at the point of change (the
+`uses:` line). This ADR, the inline comments, and the grep guard are the three
+defence layers that replace that missing breadcrumb.
+
+---
+
+## Decision
+
+**Pin all `actions/upload-artifact` and `actions/download-artifact` call sites to `@v3`.**
+
+Both action families share the same v4 protocol incompatibility with `act_runner`.
+Pinning to the major tag (`@v3`) keeps us on the latest v3 patch without Renovate noise.
+
+Three call sites are pinned:
+- `.gitea/workflows/ci.yml` — "Upload coverage reports" step
+- `.gitea/workflows/ci.yml` — "Upload screenshots" step
+- `.gitea/workflows/coverage-flake-probe.yml` — "Upload coverage log on failure" step
+
+Each pinned `uses:` line carries a load-bearing inline comment:
+
+```yaml
+# Gitea Actions (act_runner) does not implement upload-artifact v4 protocol — pinned per ADR-014. Do NOT upgrade. See #557.
+- uses: actions/upload-artifact@v3
+```
+
+A CI grep guard enforces the constraint automatically (see below).
+
+---
+
+## Consequences
+
+### Enforcement layers (defence in depth)
+
+1. **Inline comments** on every `uses:` line — visible at the point of change.
+2. **CI grep guard** in `.gitea/workflows/ci.yml` ("Assert no (upload|download)-artifact
+   past v3") — fails the build if a future commit re-introduces `@v4` or higher on any
+   workflow file. Anchored to YAML `uses:` lines to avoid false positives on embedded
+   shell strings. Includes a self-test that proves the regex catches v4+ before scanning
+   the repo.
+3. **This ADR** — canonical rationale; cross-referenced by comments and guard message.
+
+### How to spot the symptom
+
+- Test suite output shows green (vitest, surefire, pytest all exit 0)
+- CI job status shows red
+- Artifacts section of the run is empty
+- Build log shows a non-zero exit from the `Upload …` step immediately after green tests
+
+### `@v3` maintenance-mode status
+
+GitHub placed `actions/upload-artifact@v3` in maintenance mode (no new features) but it
+has not been removed and carries no known unpatched CVE as of this writing. If GitHub
+publishes a v3-specific security advisory, that is an additional trigger to re-evaluate
+(see upgrade conditions below).
+
+### When to remove this pin
+
+Re-evaluate pinning **when either condition is met:**
+
+1. `gitea/act_runner` ships a release with v4 artifact protocol support. Track upstream:
+   <https://gitea.com/gitea/act_runner>
+2. `actions/upload-artifact@v3` acquires an unpatched CVE that cannot be mitigated
+   at the runner level.
+
+When upgrading: remove the grep guard step, update all three `uses:` lines, remove the
+inline comments, and update this ADR's status to Superseded.
+
+---
+
+## Alternatives
+
+### SHA pinning (`uses: actions/upload-artifact@<sha>`)
+
+More secure against action repository compromise, but adds Renovate update friction
+and is disproportionate for a self-hosted, single-tenant Gitea instance with one
+trusted contributor (ADR-011). Rejected.
+
+### Minor/patch pinning (`@v3.4.0`)
+
+Avoids Renovate PRs but freezes us on a specific patch. The v3 major track is in
+maintenance mode — minor pinning has no benefit and would require manual updates
+for any v3 security patches. Rejected.
+
+### Renovate `packageRules` bypass
+
+Would prevent automated PRs from proposing v4. Not needed while Renovate is not
+configured for this repository. Revisit if Renovate is introduced.
+
+### Migrating the runner to a v4-compatible Gitea release
+
+Out of scope for this issue. A separate decision; tracked in #557's non-goals.
