Subagent Reports

Full specialist reports were produced by 10 read-only subagents. Each returned a structured markdown report with a findings table and per-finding detail blocks (ID, severity, confidence, files:lines, scenario, expected/actual, root cause, impact, evidence, test coverage, fix direction, complexity, regression test, runtime-confirmation flag). The parent agent re-verified the Critical/High claims directly (see VERIFICATION_LOG.md) and consolidated/deduplicated into FINDINGS.json (53 findings).

Report index (all reports were reviewed in full by the parent)

6 Material groups / ordering / drag-drop / deletion / orphans sa_20260806_054030_000000000_9ae1f3dfa282 GRP-01 Critical drift (independent confirmation); GRP-02..07: unvalidated groupId/sortOrder, fire-and-forget reorder, sortOrder duplicates after group deletion, keyboard a11y, desc-convention fragility; verified: FKs enforced, uncategorized mapping, cascade safety
7 Frontend state / refresh / races / localStorage / boundaries sa_20260806_054030_000000000_0e17fd155702 FE-01..11: optimistic reorder without rollback, CRUD res.ok ignored, shared quiz reshuffle (unstable prop), finish double-submit, progress race, FE-06 (later refuted — proxy exists), dashboard fetch gap, unguarded JSON.parse, effect fetches, cross-class race, collapse flash; verified: shared viewers read-only, localStorage clean, no boundary violations
8 Test quality / coverage / false confidence sa_20260806_054030_000000000_cd3652deb3f7 TEST-01..10: false-confidence SRS test, zero tests for scoring/auth/services/routes, no DB harness, CI never runs tests; ranked missing-test gaps by impact

10 Adversarial review sa_20260806_055608_000000000_c550c742d5dc Challenged all Critical/High findings: confirmed drift, secret, retake, port, dockerignore, override; weakened OPS-02 (fresh-volume migrate succeeds) and FE-01 severity; refuted FE-06 (proxy active — verified in compiled .next artifacts); added ADV-01..10 (retake progress pollution, activity scan, logout, dashboard crash, slugify empty slug, unguarded parses, completed-resume, localStorage key collisions, first-login race, progress validation)
