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).
Drives all infra src files to 100% (env.ts, db/client.ts, db/ensure-dir.ts,
db/migrate.ts, db/seed.ts, routes/health.ts).
- env.test.ts: dev defaults when unset, overrides when set (PORT coerced),
CORS_ORIGINS parsing (trim + drop empties) and empty-fallback.
- db.test.ts: runMigrations idempotency; ensureDbDir no-op for non-file URLs
and bare filenames (branch coverage).
- seed.test.ts: production guard — no dev users seeded when NODE_ENV=production.
- c8-ignore the migrate.ts/seed.ts CLI direct-run blocks (unreachable under vitest).
No lifecycle test (infra domain, per plan). No bugs found — infra code correct;
only coverage gaps. All 112 API tests green; typecheck + oxlint clean.
