Cycle-3 retrospective:
- 6 tasks (AZ-491..AZ-496), 5 batches, 18 SP delivered.
- 100% code review pass rate (5/5 PASS_WITH_WARNINGS, 0 FAIL).
- 0 Critical/High/Medium review findings; 7 distinct Low.
- Security audit PASS_WITH_WARNINGS: 0 new Medium, 3 Low (all
test-only or operator-CLI), 2 Informational, 1 False Positive.
- Net Architecture delta: **-3** (F-AUTH-2 + D1 + D3 RESOLVED;
only new findings are Low test-side surfaces). First
net-negative cycle on record.
- 5 of 6 tasks completed first attempt (no post-review fix
commits). Cycle-2's 2 prior-retro actions all translated to
closed work (AZ-491 from Action 1, AZ-492 from Action 2,
AZ-493 from Action 3).
Top 3 cycle-4 improvement actions surfaced:
1. Execute the perf harness to capture PT-07/PT-08 baseline.
2. Bump TestSupport JWT pins 7.0.3 → 7.1.2+ (D4 NU1902 cleanup).
3. Add `workspace:` tag to cross-repo ACs in task-spec writing
and render them separately in the traceability matrix.
3 new ring-buffer lessons appended to _docs/LESSONS.md:
- [process] Option-B forcing functions for cross-team blockers.
- [process] ACs prescribing a measurement should also prescribe
the collection path.
- [process] Cross-repo-write ACs need workspace tags.
Structural snapshot at structure_2026-05-12_cycle3.md records the
new SatelliteProvider.TestSupport project (+2 ProjectReference edges
into it; no production-layer dependents) and the AZ-496 package
bumps (8.0.21 → 8.0.25).
Cycle 3 COMPLETE. State advanced to Step 9 (New Task) for cycle 4
per existing-code flow Re-Entry After Completion.

Cycle-2 retrospective covering AZ-487 + AZ-488. Captures six patterns
(duplicate JWT helpers diverged then both broke; pre-existing
test bugs unmasked by downstream test pressure; cycle 1 perf-NFR
action stopped adding scenarios but did not drain backlog; doc-path
F1 carried over twice with no decision; integration test DB
isolation = wallclock workaround; 8 SP friction observable even
with user override). Top-3 improvement actions: consolidate JWT
mint helpers, promote PT-07/PT-08/JWT-attach to real PBI, real
integration DB-reset hook.
LESSONS.md ring buffer now holds 6 entries (testing x3, process x2,
estimation x1).
Structural snapshot: 6 components / 12 PR edges unchanged; contract
coverage 14% -> 29%; new external NuGet edges (JwtBearer 8.0.21 +
ImageSharp 3.1.11) tied to cycle-2 security findings.
Autodev pointer advances to cycle 3 / Step 9 New Task.

Two integration-test failures uncovered after the initial commit:
1) GetTilesByRegionAsync outer ORDER BY referenced 'updated_at' but
the inner DISTINCT ON subquery aliased it to 'UpdatedAt' (Postgres
folds to 'updatedat'). DISTINCT ON already guarantees one row per
(latitude, longitude, ...) so the third tiebreak was unreachable;
removed it.
2) Dapper 2.1.35 silently bypasses SqlMapper.TypeHandler<T> for enum
types during read deserialization (Dapper issue #259). The
TileSourceTypeHandler worked for writes but reads fell through to
Enum.TryParse, which cannot map 'google_maps' to GoogleMaps.
Pivoted: TileEntity.Source is now a string (the wire value).
TileSource enum stays as the public producer surface in
Common.Enums; TileSourceConverter (Common.Enums) provides
ToWireValue / FromWireValue / IsValidWireValue at the boundary.
TileSourceTypeHandler deleted; registration removed from
DapperEnumTypeHandlers.RegisterAll.
tile-storage.md Inv-5 amended to document the storage choice.
_docs/LESSONS.md L-001 records the Dapper bypass for future cycles.
Full suite passes (213 unit + integration suite incl. AZ-484
AC-1..AC-5, security SEC-01..SEC-04, AZ-356/362/357).
