Fills the session-part coverage gaps in src/routes/admin.ts (cross-user list,
active list, manual create/edit, admin stop/discard) and adds the admin↔worker
lifecycle test.
New route-level tests (apps/api/test/admin.test.ts):
- manual create: 400 on schema-invalid body; 400 when paused_seconds > span.
- edit: 404 non-numeric id; 400 schema-invalid body; 400 unparseable start_time;
400 paused_seconds > span; 404 unknown activity.
- stop: 404 non-numeric/unknown id; folds an open pause into paused_seconds.
- discard: 404 non-numeric/unknown id; 409 when already closed.
Lifecycle (apps/api/test/integration/admin-worker-session.test.ts): worker
starts → admin stops via the admin endpoint → session lands in /api/admin/report
and /api/admin/export with matching totals (uses resetDb for exact counts).
admin.ts session parts now at 100% stmts/lines; every session-part branch
covered. The one remaining session-part branch (row.pausedSeconds ?? 0 in the
stop route) is c8-ignored — paused_seconds is NOT NULL DEFAULT 0, so the null
branch is DB-impossible. The remaining uncovered branches in admin.ts are the
report/export parts, owned by the Reports domain (B-A6).
No behavior-changing bugs found; all session-part code was already correct.
Drives src/routes/sessions.ts and src/lib/work-session.ts to 100%
stmts/branch/funcs/lines (branch was 84.12% / 83.33%).
- sessions.test.ts: added error/edge branch tests — malformed-JSON start
(400), non-numeric id on pause/resume/stop/discard (404), pause/resume of a
no-longer-active session (409), discard missing (404) + already-closed (409),
stop missing (404), and discard ownership scoping (user B → 404).
- work-session.test.ts: mapper unit tests — null insoleType, nullish
pausedSeconds → 0, null durationSeconds/notes, full-field shape with
activity/user opts, and opts defaulting to undefined.
- test/integration/worker-session-lifecycle.test.ts: the anchor lifecycle test
(start→pause→resume→stop→history→export).
No bugs found — the code was correct. The two remaining uncovered branches were
the defensive `row.pausedSeconds ?? 0` guards in resume/stop; pausedSeconds is
NOT NULL DEFAULT 0 in the schema, so the null branch is unreachable via any
route. Annotated both with `/* c8 ignore next -- reason */` (comment only, no
behavior change).
