test(geschichten): add drafts to the overview page test mock data

PR #813 made +page.svelte read data.drafts, which the load function
always returns, but the pre-existing page.svelte.test.ts mock predates
the field — all 15 tests crashed with TypeError on main after merge.

Closes #814

+-- 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
+-- row and the @-mention sidecar row are dropped.
+--
+-- 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.

 **seeded rank** (`Person.generation`) — the imported generation index on a `Person` (G 0 = founders, increasing downward), used as a strict row anchor in `buildLayout.ts`. 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.
+**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.
-_Not to be confused with [parented](#parented-layout)_ — loose is the absence of parent edges into the graph.
 
-**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).

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).
