Oleksandr Bezdieniezhnykh 8b7d8a4275 [AZ-556] [AZ-557] Close cycle-2 hotfix sprint, hand off to Run Tests
Archive AZ-556 + AZ-557 task specs, mark dependencies table 25/25 done
(82/82 pts), write batch_06_cycle2_report.md and the sprint-level
implementation_report_auth_modernization_cycle2_hotfix.md, advance
_autodev_state.md to step 11 (Run Tests).

Per implement skill step 16, the final-suite gate is owned by the
test-run skill; not run here to avoid duplicate full runs.

Batch Report

Batch: 6 (cycle 2) Tasks: AZ-556 (unify_login_error_codes), AZ-557 (mfa_brute_force_lockout) Date: 2026-05-14 Commit: 4bf2e68 on dev

Task Results

Task Status Files Modified Tests AC Coverage Issues
AZ-556 unify_login_error_codes Done 8 files E2E updated/new 6 of 7 covered (AC-5 deferred) 1 Medium spec-gap
AZ-557 mfa_brute_force_lockout Done 4 files 4 new E2E tests 6 of 7 covered (AC-4 by code-attachment + AZ-537 stub parity) 1 Medium, 1 Low spec-gap

Files Modified

Production:

  • Azaion.Common/BusinessException.cs — new InvalidCredentials = 70; deprecation notes on 5 legacy members
  • Azaion.AdminApi/BusinessExceptionHandler.cs — map InvalidCredentials → 401
  • Azaion.Common/Entities/AuditEvent.cs — new LoginFailedUnknownEmail, LoginFailedDisabled
  • Azaion.Services/AuditLog.cs — new recorders; CountRecentFailedLogins aggregates both event types
  • Azaion.Services/Security.csDummyHashForTiming + VerifyDummy
  • Azaion.Services/UserService.cs — rewritten ValidateUser; new RegisterMfaFailedLogin; shared RegisterFailedLoginCore with FailureKind enum
  • Azaion.Services/MfaService.cs — lockout + rate-limit checks BEFORE TOTP verify; counter reset on success; delegates failure accounting to UserService
  • Azaion.AdminApi/Program.cs/login/mfa user-not-found → InvalidCredentials

Tests:

  • e2e/Azaion.E2E/Tests/AuthTests.cs — renamed + updated 2 tests; added 2 new (byte-equality + disabled-account audit row)
  • e2e/Azaion.E2E/Tests/PasswordHashingTests.cs — assert 401 + code 70
  • e2e/Azaion.E2E/Tests/LoginRateLimitTests.cs — assert 401 + code 70 + Retry-After
  • e2e/Azaion.E2E/Tests/SecurityTests.cs — disabled-user test aligned with new contract
  • e2e/Azaion.E2E/Tests/MfaLoginTests.cs — new AZ557_AC1, AZ557_AC2, AZ557_AC5, AZ557_AC7

AC Test Coverage: 12 of 14 covered + 2 with documented deferrals

AC Covered by Notes
AZ-556 AC-1 Login_with_unknown_email_returns_401_invalid_credentials + identical-body comparison test Audit-row check included
AZ-556 AC-2 Login_with_wrong_password_returns_401_invalid_credentials + existing AZ-537 fail-count tests
AZ-556 AC-3 Login_with_disabled_account_returns_401_invalid_credentials_indistinguishable_from_wrong_password Byte-equality + login_failed_disabled audit row asserted
AZ-556 AC-4 Audit-row assertion on AC-3 test (real-hash verify would never produce login_failed_disabled) Indirect but tight
AZ-556 AC-5 Deferred — structural mitigation only (VerifyDummy uses identical Argon2id params) See finding F1 in review report
AZ-556 AC-6 Per-category audit-row assertions in AC-1 and AC-3 tests
AZ-556 AC-7 LoginRateLimitTests.AC3_Per_account_threshold_locks_account_returns_423 (now 401 + Retry-After)
AZ-557 AC-1 MfaLoginTests.AZ557_AC1_Wrong_MFA_at_threshold_locks_account_and_audits_mfa_login_failed Seeded counter at threshold-1 for isolation
AZ-557 AC-2 MfaLoginTests.AZ557_AC2_Mixed_password_and_MFA_failures_aggregate_to_lockout
AZ-557 AC-3 Behaviourally via AC-1/AC-2 (counter aggregates both event types) See finding F2 — direct unit test deferred
AZ-557 AC-4 Code-attachment (Program.cs:374) + AZ-537 stub-parity See finding F3 — behavioural test would destabilise suite
AZ-557 AC-5 MfaLoginTests.AZ557_AC5_Locked_account_at_MFA_step_returns_invalid_credentials_with_retry_after Lockout dominates valid TOTP
AZ-557 AC-6 Audit-row assertion in AC-1 test
AZ-557 AC-7 MfaLoginTests.AZ557_AC7_Correct_TOTP_after_partial_failures_resets_counter

Code Review Verdict: PASS_WITH_WARNINGS

See _docs/03_implementation/reviews/batch_06_cycle2_review.md.

Auto-Fix Attempts: 0

All findings accepted as documented (no code changes required).

Stuck Agents: None

Open Questions (for the user)

  • AZ-557 recovery-code-during-lockout: the original Jira description listed an AC bullet "Locked-out user can still complete recovery-code login (recovery codes follow their own one-time-use semantics)" that did NOT survive into the local task spec _docs/02_tasks/done/AZ-557_mfa_brute_force_lockout.md. The current implementation treats recovery codes the same as TOTP under lockout (rejected). If the Jira AC was intentional, a follow-up is needed to bypass the lockout check on the recovery-code branch only.

Next Batch

All cycle-2 hotfix tasks complete. Autodev auto-chains to Step 11 (Run Tests). Final implementation report for the cycle handed off to test-run/SKILL.md.

Process Notes

  • Step 14.5 cumulative review is per-skill spec triggered every 3 batches. Cycle 2 has no cumulative review files (_docs/03_implementation/cumulative_review_*.md absent). Surfacing as an explicit user decision in the end-of-turn summary rather than back-filling six batches of cumulative review inline.
  • Step 15 Product Implementation Completeness Gate: both task specs name only internal admin code (no external SDKs, hardware, or cloud integrations to verify). Promised behaviour — InvalidCredentials, VerifyDummy, shared lockout pipeline, audit recorders — all has production code paths and is wired through MapPost("/login") / MapPost("/login/mfa"). PASS.
