The strategy slug → flag mapping (`_FC_BUILD_FLAGS`, `_GCS_BUILD_FLAGS`) is the single source of truth; per-binary bootstrap modules (forthcoming in AZ-393 / AZ-394 / AZ-397) call `register_fc_adapter("ardupilot_plane", factory)` under the matching `BUILD_FC_*` flag. +- **Config-load gate (AC-5)** lives in `FcConfig.__post_init__` / `GcsConfig.__post_init__`. Unknown strategies raise `ConfigError` synchronously during config construction, before any composition root code runs — failures surface at the same site as required-env-var failures. +- **Cross-FC arithmetic equality (AC-9 for AZ-392)**: `CovarianceProjector` uses the closed-form 2×2 eigenvalue formula instead of `numpy.linalg.eigvalsh`, so AP `m` and iNav `mm` round-trip exactly (every iNav call is the same `radius_m` then `round-half-up(* 1000)`). +- **iNav clamp at uint16 max** emits a single WARN per clamp event AND a single FDR record (`kind="c8.cov_projector.inav_clamped"`) so post-flight tooling can count clamp events without depending on log retention. +- **Single-writer outbound (AC-6)** lives in `fc_factory.bind_outbound_emit_thread`. The runtime root must call this once per process before wiring outbound emit; the returned thread id is the one the adapter checks on every outbound call. Re-binding from a different thread raises `OutboundThreadAlreadyBoundError`. Re-binding from the SAME thread is idempotent (test-friendly). + +## Dependencies + +**Zero new external dependencies.** AZ-390 + AZ-392 are stdlib + numpy (already pinned). `pymavlink` + `YAMSPy` enter in batch 9 with AZ-391. + +## Known forward-actions + +1. **AZ-391** (deferred to batch 9) will add the inbound `subscribe_telemetry` body for both AP (`pymavlink`) and iNav (`YAMSPy`), with the MAVLink/MSP2 decoders and Invariant 7 out-of-order drop.

YAMSPy entry is gated on AZ-391 (batch 9). +- **Module-layout adherence**: `_covariance_projector.py` is prefixed `_` per `module-layout.md` rule "internal helpers MUST start with `_`"; `c8_fc_adapter/__init__.__all__` exposes ONLY the contract symbols (asserted by `test_smoke.test_internal_modules_not_in_public_all`). +- **Layer 1 (helpers) discipline**: `fc_factory.py` imports only from `gps_denied_onboard.config`, `gps_denied_onboard.logging`, and `gps_denied_onboard.components.c8_fc_adapter.{errors,interface}`. No upward imports from c8 internals into the composition root. +- **ADR-002 build-time exclusion**: the `_FC_BUILD_FLAGS` mapping is the single source of truth tying a strategy slug to its build flag. The factory consults `os.environ` (not config) because flag state is a build-time artifact per the ADR. +- **ADR-009 interface-first DI**: all factories take `**deps` keyword args; concrete strategies are registered via `register_fc_adapter(slug, factory)` from per-binary bootstrap modules, never imported directly by the composition root. +- **AC-NEW-3 (every payload class from t=0) preserved**: this batch did NOT wire `take_off` to call `build_fc_adapter` (the strict ordering is already enforced by batch 7's `take_off`); only the factory itself landed. The wire-up happens when the first concrete adapter (AZ-393) lands. +- **Single-writer outbound thread (AC-6 / Invariant 8)**: `bind_outbound_emit_thread` is process-global state guarded by a single lock; idempotent on same-thread re-binds (test-isolation friendly). + +## Phase 4 — Performance & reliability + +- **Factory build path is O(strategy-name-lookup)**: two dict lookups + one env-var read; AC-NFR sanity check verifies < 50 ms (typically < 100 µs measured locally). +- **CovarianceProjector is O(1) per call**: 2×2 closed-form eigenvalue, no LAPACK dispatch. `test_nfr_perf_projector_under_100us_per_call` verifies < 100 µs avg over 1k iterations. +- **iNav clamp path emits at most one WARN + one FDR record per occurrence** — no rate-limit needed because the clamp itself is a per-frame event already gated by the projector call rate (5 Hz emit per AC-1.4). +- **SPD violation path is allocation-light**: one numpy view (`cov_arr[:3, :3]`), one 2×2 sub-view, two scalar reads. The FDR enqueue happens BEFORE the raise so the operator gets the post-flight forensic record even if the upstream caller swallows the exception. + +## Phase 5 — Test quality + +- **AC-1 Protocol tests use real stub classes** (not `mock.MagicMock`) so `isinstance(x, FcAdapter)` exercises the `@runtime_checkable` protocol-fingerprint check honestly. +- **AC-2 DTO tests parametrise over EVERY contract DTO**, asserting both frozen-instance immutability AND `__slots__` presence. Forgetting `slots=True` on a new DTO fails the matching parametrise. +- **AC-3 enum tests assert exact member set** (not a subset) — adding an unintended enum member also fails the gate. +- **AC-4 / AC-5 tests separate the config-load gate from the build-time gate**: unknown strategy fails at `FcConfig(...)` construction; flag-OFF fails at `build_fc_adapter(config)`; unregistered-but-known-strategy fails at `build_fc_adapter` with a clear "registered strategies: [...]" message. +- **AC-6 cross-thread rebind test uses a real `threading.Thread`** — not just a different `thread_ident` argument — so the lock's cross-thread visibility is exercised. +- **AC-10 INFO-log tests pin `caplog.at_level(...)` to the exact logger name** so they don't accidentally pass on unrelated INFO records elsewhere in the process. +- **AZ-392 SPD-violation tests assert both the raise AND the FDR record** carrying `reason` + `frame_id` — a regression that drops the FDR record would not pass the raise-only test alone. +- **AZ-392 bit-stability test calls 20 times on the same input** and asserts `len(set(results)) == 1` — drift between calls (e.g. from `numpy.eigvalsh`-style round-off) fails the gate. +- **AZ-392 NFR-perf test uses `time.perf_counter`** with 1 k iterations and a 100 µs/call budget — sufficient headroom for jittery CI runners while still catching an order-of-magnitude regression. + +Arrange / Act / Assert pattern consistently applied in all new tests. + +## Phase 6 — Logging & FDR coverage + +- **`fc_factory.build_fc_adapter`**: INFO log per build (`kind="c8.adapter.strategy_loaded"`, `kv={strategy, port_device}`). +- **`fc_factory.build_gcs_adapter`**: INFO log per build (`kind="c8.gcs.strategy_loaded"`, `kv={strategy, port_device}`). +- **`CovarianceProjector`**: WARN log on iNav clamp (`kind="c8.cov_projector.inav_clamped"`, `kv={radius_mm_raw, clamped_to, frame_id}`). +- **`CovarianceProjector`**: FDR ERROR record on every projection rejection (`kind="log"`, `payload.level="ERROR"`, `payload.kind="c8.cov_projector.spd_violation"`, `payload.kv={reason, frame_id, …}`). Uses the existing `log` record kind so no FDR schema bump is needed. +- All log records follow the `kind` + `kv` convention required by AZ-266's `JsonFormatter`. + +## Phase 7 — Security & risk surface + +- **RESTRICT-COMM-2 (iNav has no signing)**: enforced at config-load by `FcConfig.__post_init__` — passing `adapter="inav"` with any `signing_key_source != "none"` raises `ConfigError` with the restriction code in the message. Covered by `test_ac5_inav_signing_key_combination_rejected`. +- **Build-flag gate uppercases the env-var value** (`os.environ.get(...).upper() == "OFF"`) so `BUILD_FC_INAV=off` is also honoured. The DEFAULT (no env var set) is ON-per-binary; concrete binaries SHOULD set it explicitly to keep the registry → flag mapping honest. +- **Strategy registry rejects duplicate registrations with different factories** (`FcAdapterConfigError`); same-factory re-registration is idempotent. This prevents a second bootstrap module from silently overriding the first. +- **No silent fallback**: every config-load / build / projection failure raises or emits an FDR record. The covariance-projector FDR enqueue is best-effort but logs its own `c8.cov_projector.fdr_enqueue_failed` so a silenced FDR doesn't hide the SPD failure. +- **`bind_outbound_emit_thread` does not unbind on its own** — `clear_outbound_thread_binding()` is intentionally scoped to test-isolation. A process that wants to re-bind in production must restart, which matches the single-writer invariant. + +## Informational findings (non-blocking) + +1. **`take_off` is not yet wired to call `build_fc_adapter` / `build_gcs_adapter`** — this is the carry-over from batch 7's PASS_WITH_INFO finding #3. The wire-up will happen when the first concrete adapter lands (AZ-393), where the `fc_factory` can be exercised end-to-end with a real adapter. Documented in the contract bump. +2. **`Subscription` Protocol has only `cancel()`** — the contract spec leaves open whether a `Subscription` should also be a context manager. We did NOT add `__enter__` / `__exit__` because no AC requires it and AZ-391 hasn't started consuming the type yet. If AZ-391 needs ctx-manager semantics, that's a v1.1.0 contract bump on `fc_adapter_protocol.md`, not a regression. +3. **`_covariance_projector.py` is intentionally NOT in `c8_fc_adapter/__init__.__all__`** — concrete adapters (AZ-393 / AZ-394) instantiate it via direct module import, since it is an internal helper. The smoke test asserts the public-API gate; no contract bump required because the projector is a concrete helper, not a Protocol. + +## Verdict + +PASS_WITH_INFO — all ACs satisfied, all tests green, no architectural drift, one minor contract bump (`composition_root_protocol.md` 1.1.0 → 1.2.0) documented inline with migration notes.
