All six ACs implemented with test seams that demonstrate the spec'd state transitions. The two AC-3 branches and the two AC-6 branches (happy + degraded) are split into separate tests for blast-radius isolation. + +**Architecture compliance**: PASS. + +- Layer 3 coordinator (`mission_executor`) imports only `shared`, `mavlink_layer`, `mission_client` (via traits in this batch), and `mapobjects_store` (via traits in this batch). No new Layer 3 ↔ Layer 3 imports. +- `MavlinkGeofenceCommandIssuer` and `MavlinkBatteryCommandIssuer` are the production wiring for the two new failsafe families; both call `mavlink_layer::MavlinkHandle::send_command(CommandLong)` via the existing `mavlink_layer` Public API (same surface AZ-651's `MavlinkCommandIssuer` uses for lost-link). +- The `MAV_CMD_NAV_LAND` constant is co-located with the battery driver since that is the only family that issues it; `MAV_CMD_NAV_RETURN_TO_LAUNCH` continues to live in `internal::lost_link` and is re-exported (both families share the constant rather than defining a duplicate). + +**SRP**: PASS. +- `geofence.rs` — pure monitor + driver + production command issuer; one file because the three concepts are tightly coupled and the file is ~470 LOC. +- `battery_thresholds.rs` — same structure for battery. +- `middle_waypoint.rs` — pure replanner + types; no driver task (it is invoked synchronously by `MissionExecutorHandle::insert_middle_waypoint`). +- `post_flight.rs` — pure orchestrator + two traits; no MAVLink dependency (the push goes through `mission_client`). + +**Runtime completeness**: PASS. The `Runtime Completeness` section of the spec required real point-in-polygon, real `SYS_STATUS` decode, and real `MAV_CMD_*` issuance. All three are present: +- Point-in-polygon: ray-casting in `geofence::point_in_polygon` (deterministic, branch-coverage tested). +- `SYS_STATUS` decode: the battery driver consumes `shared::models::telemetry::UavSysStatus` which is already produced by `mavlink_layer`'s `MavlinkProjection` (AZ-649). +- `MAV_CMD_*` issuance: `MavlinkGeofenceCommandIssuer` and `MavlinkBatteryCommandIssuer` both call the production `MavlinkHandle::send_command` surface. + +**Test discipline**: PASS. Each AC maps to one named test (two branches each for AC-3 and AC-6). AAA pattern with language-appropriate comment syntax (`// Arrange` / `// Act` / `// Assert`). Spy implementations (`SpyGeofenceIssuer`, `SpyBatteryIssuer`, `SpyMissionDriver`, `SpyPusher`) record calls in `Arc>>` and are asserted on directly — no "no error thrown" tests. + +**Security quick-scan**: PASS. No string-interpolated commands; no untrusted input parsing in this batch. `BatteryOverride` signature validation is **excluded from this task's scope** (handled by `operator_bridge` per AZ-689). The driver assumes the override surface has already verified signatures upstream — this is documented in the type's docstring. + +**Performance scan**: PASS. Geofence monitor ticks at 10 Hz × O(total vertices); with the operational ≤8 fences × ≤32 vertices typical for a single mission this is a few hundred FLOPs per tick — well under the AZ-652 ≤500 ms response budget. The 100 ms tick gives a worst-case 100 ms detection latency, plus the MAVLink command round-trip; well inside ≤500 ms. + +**Cross-task consistency**: N/A — this batch contains a single task. + +## Module-layout drift (minor) + +`_docs/02_document/module-layout.md` lists `crates/mission_executor/src/internal/geofence/*` (a folder). This batch implements it as a single file (`crates/mission_executor/src/internal/geofence.rs`). The file is ~470 LOC and cohesive (pure monitor + driver + production command issuer); splitting into a folder for this batch would be premature. If a future batch adds new geofence variants (cylinder, altitude floor) or polygon preprocessing (R-tree), the file becomes a folder at that point. Flagged here so the next module-layout sync picks it up. + +## Known limitations (warnings) + +1. **`MavlinkBatteryCommandIssuer::issue_land_now` passes all `param_*` zeroed.** Per `architecture.md §7.7` this asks the airframe to pick the safest reachable landing point. If a future BIT item or operator setting wants to bias toward a specific recovery point, the issuer gains a `Coordinate` parameter at that point. Currently no caller supplies one. + +2. **`force_state_for_tests` is hidden from rustdoc but is a public symbol.** It is marked `#[doc(hidden)]` and only used by `tests/safety_and_resume.rs`. An alternative would be a `cfg(test)`-only module, but that does not work for integration tests (which compile against the public API). This is the same back-door pattern used by several existing FSM crates in the workspace. + +3. **Audit-log persistence is a `tracing::info!` call, not a database write.** The spec excludes `shared::audit` persistence from this task; the driver emits a structured `tracing::info!(target = "audit", ...)` entry which the runtime's `tracing` subscriber routes to the audit sink wired by `shared::audit` (when it lands). This matches the AZ-651 lost-link audit-log pattern. + +## Auto-fix attempts during the batch + +- `cargo fmt -p mission_executor` straightened `use mavlink_layer::{CommandLong, MavlinkHandle, SendCommandError};` after adding the production issuers. +- Removed an unused `mpsc` import from `tests/safety_and_resume.rs` (initial draft used a channel; final version uses a `watch` for telemetry replay). +- `clippy -p mission_executor --tests -- -D warnings` is green. + +## Test reproduction + +``` +cargo build -p mission_executor --tests +cargo test -p mission_executor # all green +cargo test --test safety_and_resume -p mission_executor # 12 tests; 0 failed +cargo clippy -p mission_executor --tests -- -D warnings +cargo test --workspace # all green +``` + +## Candidates for batch 10 + +- **AZ-653** `gimbal_a40_transport` — opens up the `gimbal_link` BIT evaluator slot (AZ-650 batch 8 noted it as the natural next slot). +- **AZ-689** `operator_bridge_signed_commands` — closes the upstream signature-validation gap referenced by AC-4's audit-log note here. + +Batch 10 sizing: one of the above; not both.
