Retrospective — Cycle 10 (2026-06-25)

Tasks: AZ-1113 (REST 400 error sanitizer, 2 SP). 1 task, 2 SP, 1 batch. Mode: cycle-end (autodev Step 17). Step 16.5 (Release) skipped — no scripts/deploy.sh / _docs/04_release/ harness (same pattern as cycles 1–9). Previous retro: retro_2026-06-25_cycle9.md

Implementation Summary

Metric	Cycle 10	Δ vs cycle 9
Tasks implemented	1	-1
Batches executed	1	unchanged
Total complexity delivered	2 SP	-6 SP
Avg tasks / batch	1	-1
Blocked tasks	0	unchanged
Implementation report	YES (implementation_report_rest_error_sanitizer_cycle10.md)	maintained

Quality Metrics

Code Review

Verdict	Count
PASS	1 (batch 01)
FAIL	0

No review findings — single-task security hardening with focused tests.

Security Audit (Step 14)

Finding	Status
F-AZ795-1, F-AZ795-2, F-AZ810-1	Resolved (AZ-1113)
F-AZ810-2, D-AZ795-1, D2-cy4	Open (cumulative PASS_WITH_WARNINGS)

Cycle 9 retro Action #3 shipped this cycle — first direct cross-cycle security debt closure.

Test & Perf Gates

Gate	Result
Step 11 functional	PASS — 450/450 unit + integration
Step 15 perf	PASS — 8/8 after PT-07 harness fix (runs 1–2 failed on marginal p95 noise)

Efficiency

Blocker	Resolution
Host port 5433 (perf)	docker-compose.perf.yml with ports: !reset []
PT-07 false FAIL (×2)	Queue drain + dual pass criterion (p95 or p50) in harness + performance-tests.md

Trend Comparison

Metric	Cycle 9	Cycle 10	Change
Code review FAIL rate	0%	0%	unchanged
Security Low resolved (delta)	0	3	improved
Perf scenarios pass	8/8	8/8	unchanged
Project count	10	10	unchanged
gRPC perf verified	No	No	unchanged gap

Top 3 Improvement Actions

1. Document docker-compose.perf.yml in deployment docs (~0.5 SP): add host-port conflict playbook to _docs/02_document/deployment/containerization.md — file exists from cycle 10 but is undocumented (cycle 9 retro Action #1 partial completion).

   • Impact: operators and autodev Step 15 don't rediscover 5433 conflict
   • Effort: low

2. F-AZ810-2 DateTime → DateTimeOffset on capturedAt (~1 SP): closes last cycle-10 security carry-over; wire contract already documents ISO-8601 offset.

   • Impact: cumulative security verdict → PASS
   • Effort: low

3. PT-10 gRPC stream perf scenario (~3 SP): DeliverRouteTiles time-to-first-chunk + total stream duration (cycle 9 Action #2, still open).

   • Impact: closes Unverified gRPC NFR gap
   • Effort: medium

Suggested Rule/Skill Updates

File	Change	Rationale
run-performance-tests.sh / performance-tests.md	PT-07 dual criterion now canonical — document in test-run perf mode	Cycle 10 false FAILs
containerization.md	Perf/test compose overlay section	Recurring 5433 blocker

Cycle 10 Verdict

Successful hardening cycle — three long-standing Low information-disclosure findings resolved with green gates. Release deferred (no harness); commit/push remains operator action. PT-07 harness improved for future cycles.
