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).

Add per-source tile rows to support multi-provider imagery (Google
Maps + future UAV). Migration 013 (transactional) introduces
source/captured_at columns, backfills existing rows to
(source='google_maps', captured_at=created_at), and replaces the
4-column unique index with a 5-column index that includes source.
TileRepository:
- ColumnList includes source + captured_at
- GetByTileCoordinatesAsync returns most-recent row across sources
(ORDER BY captured_at DESC, updated_at DESC, id DESC)
- GetTilesByRegionAsync uses DISTINCT ON to pick the most-recent
tile per cell, restoring caller-facing row order
- Insert/Update upsert on the new 5-column conflict key
TileSource enum lives in Common.Enums. Snake_case wire format
(google_maps, uav) is enforced by a focused TileSourceTypeHandler
because the generic ToLowerInvariant pattern would emit
"googlemaps", violating contract v1.0.0.
TileService stamps Source=GoogleMaps + CapturedAt=UtcNow on every
new tile. Tile-storage contract is now frozen at v1.0.0.
AC coverage 7/7. New unit + integration tests cover all ACs;
existing 200 unit + 5 smoke tests preserved.

Step-9 (new-task) cycle 1 artifacts for the AZ-483 multi-source tile
storage epic. AZ-485 (UAV upload + quality gate) deferred to a future
Step-9 loop and recorded as planned in the dependencies table.

Phase 6 (Verification): smoke run green (format gate + 200/200
unit + integration smoke). verification_report.md captures
metric deltas vs Phase 0 baseline; all 5 ACs met, all 4
constraints honored, 0 regressions.
Phase 7 (Documentation):
- module-layout.md: corrected DataAccess->Common dependency
(was mistakenly documented as "Imports from: (none)" by
prior AZ-315 baseline; csproj reference + 7 import sites
have actually been there since AZ-309).
- architecture_compliance_baseline.md: F5 entry revised to
reflect the actual layering invariant (one-way: Common
MUST NOT import from DataAccess, but DataAccess MAY
import from Common).
- 00_discovery.md: added "Updates Since Baseline" section
enumerating the AZ-309 split + AZ-350 27-change run +
AZ-372 tooling additions; original tree kept as a
2026-05-10 snapshot.
FINAL_report: complete run summary (10 batches, 27 tasks,
3 K=3 cumulative reviews, baseline->final metric table,
remaining items, lessons learned).
Autodev state: advance Step 8 -> Step 9 (New Task);
sub_step reset to phase 0 awaiting-invocation.

- Stop writing "downloaded_YYYY-MM-DD" into tiles.maps_version: new rows
bind @MapsVersion to NULL via TileService.BuildTileEntity.
- Retain the tiles.maps_version column (coderule.mdc forbids unprompted
column drops); pre-existing rows keep their values for forensics.
- Remove MapsVersion property from DownloadTileResponse (API wire shape)
and TileMetadata (internal DTO); OpenAPI schema regenerates from the
DTO via Swashbuckle.
- Add 3 AC tests in TileServiceTests covering the captured-entity write
(AC-1) and the DTO/wire-shape removal (AC-2).
- Update integration-test local DTO + console output; refresh docs in
common_dtos.md, services_tile_service.md, data_model.md.
- Archive AZ-373 task file: todo/ -> done/.
174 unit + 5 smoke pass.

Replaces bare strings with two enums in Common/Enums/:
RegionStatus { Queued, Processing, Completed, Failed }
RoutePointType { Start, End, Action, Intermediate }
Adds a Dapper EnumStringTypeHandler<T> (DataAccess/TypeHandlers/)
that round-trips enums to/from lowercase strings, registered once
at startup via DapperEnumTypeHandlers.RegisterAll(). DataAccess now
references Common (project ref) so entities can carry the enum types.
Sites converted: RegionService (5), RouteProcessingService (3),
RoutePointGraphBuilder (4), entity Status/PointType columns. Log
message and summary file format preserved via .ToLowerInvariant().
API JSON contract preserved by adding JsonStringEnumConverter with
JsonNamingPolicy.CamelCase to the http JSON options — single-word
enum members serialize to the same lowercase strings as before.
DTO renamed: Common.DTO.RegionStatus -> RegionStatusResponse to
free the RegionStatus name for the new enum (forced by the task's
explicit enum name); the renamed DTO has no public-API impact at
the JSON wire level. Stale doc references updated.
AC RT2 in _docs/00_problem/acceptance_criteria.md now lists all 4
point types (start/end/action/intermediate).
Tests: 171 / 171 unit + 5 / 5 smoke green (was 141 + 5; +30 new tests
covering type handler round-trip, set/parse, unknown-value rejection,
idempotent registration, and the AC RT2 doc check).

Phase C of architecture coupling refactor (epic AZ-309). Closes the
last baseline finding (F5 — DataAccess incorrectly documented as
importing Common) and synchronizes the rest of _docs/02_document/
with the post-split project layout from AZ-312/313/314:
- module-layout.md: per-component sections for the three new csprojs
with explicit ProjectReferences and the no-cross-sibling-reference
invariant the split enforces.
- architecture.md: components and internal-communication tables
updated to show calls flow through Common interfaces.
- architecture_compliance_baseline.md: F1..F5 marked Resolved with
task IDs and commit refs; baseline summary now 0 findings.
- diagrams/components.md, components/03_tile_downloader/description.md,
modules/{common_interfaces,services_tile_service,
services_google_maps_downloader,tests_unit}.md updated for the
split, RateLimitException relocation, and new ITileService methods.
Documentation-only batch — no code, no tests, no build changes.
Epic AZ-309 complete (6 tasks across 3 batches).
