Retrospective — Cycle 13 (2026-06-26)

Tasks: AZ-1126 (capturedAt DateTimeOffset, 2 SP). 1 task, 2 SP, 1 batch. Mode: cycle-end. Step 16.5 (Release) skipped (no release harness). Previous retro: retro_2026-06-26_cycle12.md

Quality

Gate	Result
Code review	PASS_WITH_WARNINGS (batch_01_cycle13)
Step 11 full suite	PASS (pre-verified in Step 10)
Step 14 security	PASS (delta) — F-AZ810-2 resolved
Step 15 perf	PASS 11/11 (first run failed: stack not up)
Step 16 deploy	PASS — deploy_cycle13.md

Cycle 13 delta

• F-AZ810-2 closed — cycle 12 retro Action #1 shipped; DateTimeOffset + strict converter eliminates DateTimeKind ambiguity on UAV upload path.
• Filter regression caught in batch — generic JsonException handler initially masked converter diagnostics; fixed by propagating exception message.
• Security finding → task → closure — 2 SP dedicated cycle resolved a multi-cycle Low carry-over without scope creep.

Comparison with cycle 12 retro actions

Cycle 12 action	Cycle 13 outcome
F-AZ810-2 DateTimeOffset (~1 SP)	Done (AZ-1126)
Align environment.md integration command	Open — not scheduled
PT-09 shell harness promotion	Open — optional

Top 3 Improvement Actions (cycle 14 candidates)

1. D-AZ795-1 — bump FluentValidation 12.0.0 → 12.1.1 (~1 SP) — sole remaining Low prod dependency finding
2. Align environment.md integration command with run-tests.sh (docker-compose.tests.yml only) (~0.5 SP) — third-cycle carry-over
3. Perf gate preflight — document or script-check that perf compose stack is up before PT-01 (~0.5 SP) — cycle 13 first-run exit 7

Cycle 13 Verdict

Successful security-closure cycle — AZ-1126 delivered a focused type migration with full gate coverage (security + perf + deploy). One auto-fix in the validation filter; no architecture drift.
