decoder integration + encoder integration + parse-error counter (`SigningMismatch`); ack demux with oneshot dispatch + deadline + `send_command` API surface on `MavlinkHandle` + `commands_in_flight()` exposed in health. ✓ +- AZ-665: `H3Index::cell_of(lat, lon, res)`, `grid_disk(cell, k)`, haversine metres, in-memory `(H3 cell → Vec)`, similar-classes group resolution, configurable thresholds, `MapObjectsStoreHandle::classify(ClassifyInput) -> Classification`. ✓ +- AZ-672: `VlmProvider::name()` diagnostic method; `DisabledVlmProvider` in `shared::contracts`; feature-gated `vlm_client::VlmClient` (placeholder until AZ-673); `autopilot` has `vlm_client` as `optional = true` dep gated by `vlm` feature; `Runtime::select_vlm_provider` picks based on feature + runtime flag. ✓ + +**Phase 2 — Architecture compliance**: +- `mavlink_layer` continues to import only `shared`; new modules live under `internal::ack_demux` and `internal::codec::signing`. Public API additions: `Signer`, `SigningKey`, `Verifier`, `SigningReject`, `SendCommandError`, `CommandAck`, `MavlinkHandle::send_command`. Layer constraint preserved. +- `mapobjects_store` imports only `shared` + `h3o` + chrono/uuid (all permitted by module-layout.md §5). New `internal/h3_index.rs` and `internal/store.rs` placed exactly where module-layout.md says. Public API exports `ClassifyInput`, `Classification`, `MapObjectsStoreConfig`, `MapObjectsStoreHandle::classify`. +- `vlm_client` is now genuinely optional in the autopilot binary (`dep:vlm_client` under `[features].vlm`). The `DisabledVlmProvider` lives in `shared::contracts` — i.e., available regardless of feature, exactly as `description.md §9 Optionality Model` requires. `scan_controller` (AZ-684 dependency target) will receive `Arc` and never link to `vlm_client` directly. +- **Doc drift** (note for next monorepo-document run, not a blocker for AZ-665): + - `module-layout.md` line 157 documents the public API as `classify(Detection) -> Classification`. AZ-665 introduces `ClassifyInput` instead because the shared `Detection` type carries no geolocation (no GPS / no MGRS) and extending it was out of scope. `system-flows.md §F7` already describes the payload as "detection (gps, class, conf, size)" — `ClassifyInput` is the typed expression of that flow-level concept. Update module-layout.md to `classify(ClassifyInput) -> Classification` in a follow-up. + +**Phase 3 — Code quality**: +- SRP holds: `ack_demux.rs` only routes acks; `signing.rs` only does HMAC + replay-detection; `h3_index.rs` only wraps `h3o`; `store.rs` only owns the in-memory map. Each has one reason to change. +- No silent error suppression. `SendCommandError` is an exhaustive enum (`Duplicate`, `Timeout`, `LinkDown`, `Other`); signing errors funnel into `ParseErrors::signing_mismatch` and surface in the public counter snapshot; haversine + cell_of return typed `AutopilotError::Validation`. +- All tests follow `Arrange / Act / Assert` per `coderule.mdc`. +- `MapObjectsStoreHandle::len()`'s clippy-required `is_empty()` companion is implemented and consistent. + +**Phase 4 — Runtime completeness (per task brief)**: +- AZ-643 "real signing with secret-key validation" — `Signer::sign_into` computes SHA-256 over the canonical signed-payload bytes and appends the 13-byte trailer; `Verifier::verify` recomputes and compares in constant time; timestamps validated against the per-link source. ✓ +- AZ-665 "real H3 + k-ring" — `h3o` 0.7 is used (no naive Euclidean fallback). ✓ +- AZ-672 "real disabled impl + feature flag" — `DisabledVlmProvider` is a concrete trait impl (not a panicking `unimplemented!`), and the binary genuinely drops `vlm_client` from its dep graph when the feature is off (verified via `cargo tree`). ✓ + +**Phase 5 — Test discipline**: +- Every AC has a dedicated test (table above). +- Performance AC (AZ-665 AC-5) uses `#[ignore]` because debug builds run 3–10× slower than release; explicit `--ignored` invocation runs it and asserts ≤ 1 ms. This is the established project pattern for perf gates. +- AZ-672 AC-2's structural-build check is expressed as a build invariant (`cargo tree` + `cargo check --no-default-features`) rather than a runtime test, because that is what the AC actually asks for.
