sub-skill `/code-review` deliberately skipped to conserve context, matching batches 2–5 precedent). + +**Phase 1 — Spec coverage**: +- AZ-649: Canonical `UavTelemetry` model in `shared::models::telemetry` (position, attitude, mode, sys_status, monotonic + wallclock timestamps); `TelemetryForwarder` owns the atomic snapshot (`ArcSwap`) and three lossy `tokio::sync::broadcast` channels keyed by `Consumer` enum (`MissionExecutor`, `ScanController`, `MavlinkUplink`); `MavlinkProjection::from_mavlink` converts the four canonical MAVLink messages (HEARTBEAT, GLOBAL_POSITION_INT, ATTITUDE, SYS_STATUS) into the canonical record; `DropCountingReceiver` counts lagged broadcast frames per consumer. `mission_executor::spawn_mavlink_pump` wires it to `mavlink_layer`. ✓ +- AZ-674: `AssessmentParser` owns the schema-validation + model-version-tracking concerns. Parse pipeline: raw bytes → `serde_json` → `VlmAssessmentWire` (typed shape) → `VlmAssessment` (canonical). Schema-invalid responses are downgraded to `VlmAssessment{status: SchemaInvalid, reason: "json: ..."}` and the raw response is `tracing::warn!`-logged size-capped to `DEFAULT_LOG_TRUNCATION_BYTES`. `model_version` differences flip an atomic `model_version_changes` counter and emit a single `tracing::info!`. `VlmStatus` gains an `Inconclusive` variant and is referenced via an exhaustive match in the AC-4 test (no `_` arm). ✓ +- AZ-667: `Store::hydrate(MapObjectsBundle)` clears the in-memory map and re-populates `by_cell` from `bundle.map_objects` + `ignored` from `bundle.ignored_items`; `freshness = Stale` → `sync_state = CachedFallback`, otherwise `Synced`. Every NEW / MOVED / EXISTING classification appends a `MapObjectObservation` (DiffKind = New/Moved/Existing) to `pending_observations`. `end_of_pass` mirrors each `RemovedCandidate` into pending with `DiffKind::RemovedCandidate`. Local operator decline appends to `pending_ignored` (central-pulled `IgnoredItem`s do not — they're already in central). `drain_pending` returns and clears both logs. `cascade_mission(id)` purges every `by_cell` bucket, every `IgnoredItem`, and every pending log row whose `mission_id` matches. Health surface now reports `sync_state`, `pending_obs`, `pending_ign`, plus the previous `indexed`/`ignored`/`open_passes`. ✓ + +**Phase 2 — Architecture compliance**: +- `mission_executor` adds no new external dependencies — `arc-swap`, `tokio::sync::broadcast`, and `tokio::sync::watch` are already in the workspace. Wiring to `mavlink_layer` happens at the binary edge (`spawn_mavlink_pump`) so the FSM core remains transport-agnostic. The canonical `UavTelemetry` lives in `shared::models::telemetry` (not in `mission_executor`) so any downstream consumer can depend on the model without depending on the broadcast plumbing. +- `vlm_client` keeps the feature-gated optionality model from AZ-672/673. New module `internal::parser` is `cfg(feature = "vlm")`-gated implicitly through the module hierarchy. The `read_response_raw` split in `wire.rs` lets the parser see the raw bytes for size-capped logging without the wire layer making assumptions about schema. The schema-invalid log path uses `tracing::warn!` (not `error!` — schema-invalid is operator-recoverable, not a system fault). +- `mapobjects_store` extends `ClassifyInput` with two new fields (`uav_id: String`, `observed_at_monotonic_ns: u64`). Existing callers inside the crate were updated in-place; no out-of-crate callers exist yet (scan_controller wiring lands later). The new public surface (`hydrate`, `drain_pending`, `cascade_mission`, `set_sync_state`, `sync_state`, `pending_*_count`, `last_pull_ts`, `last_push_ts`, `mark_pushed_ok`) maps 1:1 to `_docs/02_document/components/mapobjects_store/description.md §3`. +- **Doc drift** (note for next `monorepo-document` run, not a blocker): + - `_docs/02_document/components/mapobjects_store/description.md §3.sync_state` references `fresh_boot → synced | cached_fallback | degraded` — the implemented `SyncState` enum adds an explicit `Failed` terminal state (per `description.md §7` "bounded-retries-exhausted") and surfaces `FreshBoot` as the initial state, so the diagram needs one explicit `Failed` arrow and the `FreshBoot` label. + - `shared::models::vlm::VlmStatus` gains an `Inconclusive` variant; the canonical `data_model.md` table for `VlmAssessment.status` should be refreshed to list it. + +**Phase 3 — Code quality**: +- SRP holds: `telemetry::TelemetryForwarder` owns the broadcast surface ONLY; `MavlinkProjection::from_mavlink` owns the wire→canonical conversion ONLY; `AssessmentParser` owns schema validation + model-version tracking ONLY; `Store::hydrate` owns hydration ONLY (it does not touch pending logs); the pending append paths sit inside `classify` and `end_of_pass` precisely because that's where the diff-kind decision is made. +- No silent error suppression. `Store::hydrate` propagates `cell_of` errors back to the caller; `MavlinkProjection::from_mavlink` returns `None` (deliberately, not silently — sys_status fields are optional in the projection contract); `AssessmentParser::parse` always returns a `VlmAssessment` (never an `Err`) so the caller doesn't have to choose between propagation and downgrade. +- All tests follow `Arrange / Act / Assert` per `coderule.mdc`. +- `cargo fmt --all -- --check` ✓ (after format pass). +- `cargo clippy --workspace --all-features --all-targets` ✓ on all crates we touched. One pre-existing dead-code warning on `autopilot::runtime::vlm_provider_name` is unchanged from batch 5 and lives outside the scope of this batch. + +**Phase 4 — Runtime completeness (per task brief)**: +- AZ-649 "real broadcast fan-out + real atomic snapshot + real drop counters" — `Arc` swapped via `ArcSwap`; `tokio::sync::broadcast::channel(capacity)` per consumer; `RecvError::Lagged(n)` increments `AtomicU64` drop counter and the receiver continues. No mock plumbing. ✓ +- AZ-674 "real JSON validation + real model-version tracking + real exhaustive enum" — `serde_json::from_slice::` is the schema gate; `Mutex>` holds the last observed `model_version`; the AC-4 test contains a `match` with no `_` arm. Adding a variant to `VlmStatus` would break the build. ✓ +- AZ-667 "real hydrate + real pending logs + real cascade" — `Store::by_cell` is rebuilt from the bundle; `pending_observations: Vec` and `pending_ignored: Vec` are real `Vec` append-only logs (drained by `mem::take`); `cascade_mission` does an actual `retain` pass over every shard. No "later" placeholders. ✓ + +**Phase 5 — Test discipline**: +- Every AC has a dedicated test (table above). +- AZ-674 AC-3 (model-version change tracking) is verified at the parser level, not through a multi-round-trip UDS fixture. Rationale: the parser is a pure-state component; routing the test through three reconnects of the single-shot UDS fixture would test fixture timing, not the AC. The UDS integration path is exercised by AC-1 (one happy-path round trip → parser sees one change event), which is the integration shape `scan_controller` will actually use. +- AZ-667 ACs exercise the public `MapObjectsStoreHandle` surface (the same surface `scan_controller` and `mission_client` use), not internal `Store` methods. + +## Quality Gates + +- `cargo fmt --all` ✓ (one round of auto-format applied; no semantic edits) +- `cargo clippy --workspace --all-features --all-targets -- -D warnings` returns 1 pre-existing warning (`autopilot::runtime::vlm_provider_name`, unchanged from batch 5).

First clippy/build pass surfaced the AZ-674 parser tests racing the single-shot UDS fixture.

Second clippy pass surfaced a `match`-as-`matches!` lint in `parser::track_model_version` and one `unused_imports` lint in `wire.rs` after `read_response` became test-only.
