Resolve F-AZ1074-1/2 (collection caps, generic gRPC internal errors). Standalone integration compose stack, docs, security audit, perf and retro. Co-authored-by: Cursor <cursoragent@cursor.com>
3.3 KiB
Retrospective — Cycle 9 (2026-06-25)
Tasks: AZ-1074 (gRPC RouteTileDelivery service, 5 SP), AZ-1075 (gRPC integration tests, 3 SP). 2 tasks, 8 SP, 1 batch.
Mode: cycle-end (autodev Step 17). Step 16.5 (Release) skipped per user choice — matches cycles 1–8 pattern; changes uncommitted at retro time.

Quality Metrics
Code Review
| Verdict | Count |
|---|---|
| PASS_WITH_WARNINGS | 1 (batch 01) |
| FAIL | 0 |
Findings: 2 Low (amd64 Docker pin documentation; ArgumentException detail string formatting).
Security Audit (Step 14)
| Severity at audit | Post follow-up |
|---|---|
| Medium 1 | 0 — F-AZ1074-1 resolved (collection caps) |
| Low 1 | 0 — F-AZ1074-2 resolved (generic internal error) |
Continues cycle-8 pattern of in-cycle Medium resolution.
Test & Perf Gates
| Gate | Result |
|---|---|
| Step 11 functional | PASS — 448 unit + integration |
| Step 15 perf | PASS — 8/8 REST scenarios (gRPC unverified) |
Efficiency
| Blocker | Resolution |
|---|---|
| Host port 5433 conflict (integration + perf) | Standalone docker-compose.tests.yml; perf used ephemeral compose override |
Trend Comparison
| Metric | Cycle 8 | Cycle 9 | Change |
|---|---|---|---|
| Code review FAIL rate | 0% | 0% | unchanged |
| Security Medium open (delta) | 0 (1 resolved in-cycle) | 0 (1 resolved in-cycle) | same pattern |
| Perf scenarios pass | 8/8 | 8/8 | unchanged |

Top 3 Improvement Actions
-
Document parallel-Postgres dev workaround (~1 SP): add
docker-compose.perf.ymlor documentedports: !reset []override to_docs/02_document/deployment/containerization.mdso Step 11/15 don't rediscover the 5433 conflict each cycle.- Impact: faster integration/perf runs on multi-project dev machines
- Effort: low
-
PT-10 gRPC stream perf scenario (~3 SP): when streaming NFR is accepted, add harness scenario for
DeliverRouteTiles(time-to-first-chunk, total stream duration, backpressure).- Impact: closes Unverified gap from cycle 9 Step 15
- Effort: medium
-
REST error sanitizer sweep (~2 SP): F-AZ795-1/2 carry-over — static 400 messages in
GlobalExceptionHandler/ upload filter.- Impact: reduces cumulative Low security debt (5+ cycles)
- Effort: low–medium
Suggested Rule/Skill Updates
| File | Change | Rationale |
|---|---|---|
test-run/SKILL.md perf mode |
Note gRPC scenarios may be Unverified when only REST harness exists | Cycle 9 Step 15 |
environment.md or containerization doc |
Postgres port conflict playbook | Recurring blocker |
Cycle 9 Verdict
Successful feature cycle — gRPC delivery shipped with tests, security hardening, and green gates. Release deferred (user choice); commit/push remains operator action before production promotion.
