- rank.test.ts: 100-iteration zipper mid-point insert precision test (Pitfall 2);
rank-between-neighbors contract test; total 10 tests (was 8)
- lists.test.ts: 5 new LIST-03 ordering tests — PATCH position updates only rank
and GET returns new ASC order; one-row write asserts other items unchanged;
LWW (D-15): second PATCH overwrites first; T-04-07 two-field position PATCH → 400
- Note: tests use a0–a5 rank range (avoids uppercase ranks that sort differently
under MariaDB utf8mb4_unicode_ci vs JS lexicographic order)
- GET /: scoped access (owner + list_shares); activeCount/doneCount per list
- POST /: auto-populates list_shares for all other members when isShared=true (D-01/D-02)
- PATCH /🆔 rename + isShared toggle; reconciles list_shares on visibility change
- DELETE /🆔 owner-only; cascade handles items/shares via FK onDelete cascade
- resolveUserId helper copied verbatim from events.ts per project convention
- zod createListSchema (name 1..255, isShared default true) + patchListSchema
- T-04-02 / T-04-05 / T-04-07 / T-04-08 mitigations applied
- listsRouter mounted at /api/lists in index.ts (after sseRouter)
- Plan 06 SSE seam comments left at every mutation handler
- [Rule 1 - Fix] zValidator returns 400 (not 422); tests corrected to match convention
- All 23 tests green; full API suite 140 passed no regressions
The two Wave-0 RED stubs (lists.test.ts, listEmitter.test.ts) were co-located in
src/ but all existing API tests live in apps/api/tests/. Move them to tests/routes/
and tests/lib/, add explicit vitest imports to match the tests/ convention, and
update path references in downstream plans 04-02..04-06. PWA tests keep co-location
(that IS the PWA convention).
