Implement KltRansacStrategy, the ADR-002 engine-rule mandatory
simple-baseline VioStrategy for E-C1. Pure-Python facade over
OpenCV's cv2.goodFeaturesToTrack / calcOpticalFlowPyrLK /
findEssentialMat / recoverPose pipeline — no C++/pybind11 binding
by design so a Tier-0 workstation runs the strategy with
`pip install opencv-python` and the BUILD_KLT_RANSAC=ON gate alone.
Constructor + state machine + FDR transition spine mirror
Okvis2Strategy + VinsMonoStrategy so the AZ-331 factory + IT-12
comparative harness treat all three as drop-in substitutable; the
duplication is the consolidation target now formally in scope for
the next cumulative review (batches 52-54).
AC coverage: AC-1..AC-11 + NFR-perf mapped to passing tests
(25 tests, 23 pass + 2 tier-2 skipped on dev/CI runners; all 25
pass under GPS_DENIED_TIER=2). Honest-covariance invariant (AC-9)
implemented as residual-scatter / (N_inliers - 5) with an inlier-
count penalty — no client-side floor or smoother; cov Frobenius
grows monotonically across DEGRADED. Camera-agnostic source
(AC-11) enforced by CI-grep gate that excludes docstring text.
Test-Run Cadence: focused suite tests/unit/c1_vio/ green (95 passed,
6 skipped); config-loader + compose-root suites green; full-suite
gate deferred to Step 16 per implement skill.

VinsMonoStrategy: Python facade conforming to AZ-331 Protocol; mirrors
the AZ-332 OKVIS2 facade so the AZ-331 factory + IT-12 comparative
harness can treat both as drop-in substitutable. Native binding is a
pybind11 skeleton compiled behind BUILD_VINS_MONO=ON (default OFF for
airborne / operator-tooling / replay-cli per module-layout.md
Build-Time Exclusion Map). Real vins_estimator wiring is the Tier-2
follow-up.
VinsMonoConfig added to c1_vio/config.py with sliding-window /
feature-tracker / marginalisation / opt-iteration knobs plus
__post_init__ validation; exported through the package __init__.
cpp/vins_mono/CMakeLists.txt replaces the AZ-263 placeholder with full
pybind11 wiring: Risk-1 mitigation forces VINS_MONO_USE_ROS=OFF;
Risk-2 mitigation links Eigen from the same cpp/_third_party/eigen pin
as OKVIS2; Risk-3 mitigation enforces BUILD_VINS_MONO=OFF in
deployment binaries via the gate at the top of the file.
Tests: 17 new in test_vins_mono_strategy.py (15 pass + 2 tier2 skip);
fake_vins_mono_binding fixture added to conftest.py mirroring the
fake_okvis2_binding pattern; test_protocol_conformance updated to drop
vins_mono from _STRATEGIES_WITHOUT_PY_MODULE so the existing
parametrised factory tests route through the new strategy.
Focused c1_vio suite: 72 passed, 4 skipped. Full suite: 1788 passed,
1 unrelated pre-existing flake (c12 cold-start perf, env-bound).

Adds two research-only VprStrategy implementations for the IT-12
comparative-study matrix. MegaLocStrategy (D=2048, 322x322) and
MixVprStrategy (D=4096, 320x320), both via C7 TensorRT FP16 with
their own concrete BackbonePreprocessor. Single-stage global L2
normalisation; retrieval delegated to FaissBridge; FDR records +
structured logs identical to UltraVPR. BUILD_VPR_MEGALOC and
BUILD_VPR_MIXVPR ON for research/replay-cli only, OFF for airborne
and operator-tooling (fail-fast at composition root via existing
AZ-336 factory). Uses helpers.iso_ts_from_clock from day 1 — no
new timestamp helper duplicates introduced.
36 parametrised AC tests + 25 protocol-conformance + 18 helper
regression tests pass; 1690 / 1690 unit tests pass (excluding 1
pre-existing flaky cold-start subprocess test in c12). Verdict:
PASS_WITH_WARNINGS — one Medium follow-on (AZ-527 to consolidate
4-way _assert_engine_output_dim) + one Low AC wording drift.

Closes cumulative review 46-48 F1 (Medium) + F3 (Low). Adds
iso_ts_from_clock(clock) alongside iso_ts_now() in the Layer-1
helper; migrates four duplicate definitions in c2_vpr (net_vlad,
ultra_vpr, _faiss_bridge) and c12_operator_orchestrator
(operator_reloc_service). Output format flipped +00:00 -> Z to
align with iso_ts_now() and the canonical FDR _TS fixture (FDR
schema test passes unmodified).
18 helper AC tests + 186 sibling tests pass; ruff clean.

Batch 48 / Cycle 1 (greenfield Step 7). Closes cumulative review
batches 31-33 F2 and 28-30 F3 by replacing the duplicated private
_iso_ts_now() one-liners with a single Layer-1 helper:
src/gps_denied_onboard/helpers/iso_timestamps.py
iso_ts_now() -> str
Output format matches the canonical FDR _TS fixture
(YYYY-MM-DDTHH:MM:SS.ffffffZ); no FDR schema change.
Migrated call-sites (3): c7_inference/onnx_trt_ep_runtime,
c7_inference/thermal_publisher, plus the 3 c6_tile_cache callers
that previously imported from the local c6_tile_cache/_timestamp
shim (now deleted, superseded by the Layer-1 helper).
Spec drift resolved (Choose A, user-approved): spec listed 5 call
sites + +00:00 regex; on-disk reality at batch start is 3 sites +
Z-suffix matching every existing helper and the FDR _TS fixture.
Spec preamble + AC-2 regex updated in the task file; documented in
batch_48_cycle1_report.md.
Tests: 9 new AC tests (AC-1..AC-7 + Layer-1 invariant +
public-surface defensive); 216 focused tests pass including the
unmodified AZ-272 FDR schema suite and AZ-270 / AZ-507 layering
lints. Verdict: PASS (no findings).

Implements F1 pre-flight cache build orchestrator on the operator
workstation. Composes C11 TileDownloader (AZ-316), C12 CompanionBringup
(AZ-327), C12 FlightsApiClient (AZ-489), and the new
RemoteCacheProvisionerInvoker into one sequenced flow guarded by a
filelock-backed workstation-side lockfile.
Architectural decisions:
- Phase-0 flight-resolve runs BEFORE the lockfile (ADR-010): a flight
that cannot be resolved is an operator-input error, not a contended-
resource error. Enforced by AC-11 + AC-14.
- Consumer-side cuts (AZ-507) for C11 + C10 types: local Protocols /
mirror DTOs in tile_downloader_cut.py and _types.py; external errors
matched by name-based whitelisting so unknown exceptions still
propagate per AC-6. Cross-component type translation lives at the
composition root (c12_factory).
- Failure surfacing: recognised operational failures (download error,
companion not ready, build error, flight-resolve error) return as
CacheBuildReport(outcome=failure, failure_phase=...). Only lockfile
contention raises (BuildLockHeldError) since no phase ever ran.
- Workstation-side filelock library (project pin); no custom primitive.
- Remote C10 stdout streamed line-by-line as DEBUG with api_key /
auth_token redacted before logging (defence-in-depth).
- CLI is now a thin adapter; all workflow logic lives in
build_cache.py. operator-tool build-cache exit codes map per
CacheBuildReport.failure_phase + failure_exception_type.
Tests: 116 c12 unit tests pass (29 new for AZ-328 covering 15/15 ACs +
NFR-perf-overhead microbench; 7 new for remote_c10_invoker; 3 new for
file_lock; test_cli_build_cache rewritten for new orchestrator
interface). Full repo suite: 1522 passed, 80 skipped.
Also: replays Batch 42's ruff format leftover for c12 flights_api +
test_az489 files (formatter ran over the c12 directory after new
files were added). Pure whitespace; no behaviour change.

Wraps HttpTileUploader (AZ-319) with two bounded retry budgets:
- In-call (per-batch) — re-invokes inner on PARTIAL outcome up to
`max_in_call_retries` times with capped exponential backoff
(`min(base ** attempt_number, cap)`). On exhaustion: surfaces an
operator hint via `next_retry_at_s = now + backoff_cap_s`.
- Per-tile (cross-call) — atomically increments c6's
`tiles.upload_attempts` counter for every rejection; once a tile
hits `max_per_tile_attempts` it is forward-only transitioned to
`voting_status = upload_giveup` (excluded from `pending_uploads`).
Each transition emits FDR `kind="c11.upload.giveup"` plus an
ERROR log.
C6 contract changes (AZ-303 v1.3.0):
- VotingStatus.UPLOAD_GIVEUP added (forward-only from PENDING/TRUSTED).
- TileMetadataStore.increment_upload_attempts(tile_id) -> int added
with NotImplementedError default for backwards-compat.
- Migration 0003_c11_upload_attempts: additive column +
widened ck_tiles_voting_status (preserves IS NULL clause).
C11 wiring:
- C11RetryConfig + disable_retry_decorator on C11Config.
- build_tile_uploader wraps in decorator by default; bypass flag
returns the bare HttpTileUploader. New `clock` keyword.
Cross-component isolation honoured (AZ-507): the decorator declares
`_RetryMetadataStoreLike` Protocol cut over c6's TileMetadataStore
and references `UPLOAD_GIVEUP` via a local string constant — no c6
imports.
Tests: 13 decorator + 1 conformance + 2 factory bypass + AC-6 enum
update + alembic head bump + AZ-272 schema fixture. 238 passed across
c11/c6/fdr suites; pre-existing perf microbenches unrelated.
Code review: PASS_WITH_WARNINGS (5 Low/Informational findings,
docs-level or downstream-CI-blocked). See

Lands the production HttpTileUploader composing AZ-317's gate, AZ-318's
per-flight signing, and consumer-side cuts over c6 storage. Implements
the full upload flow: gate ON_GROUND -> start_session -> enumerate
pending -> per-batch multipart POST with Ed25519 signing -> mark_uploaded
on ack -> end_session in finally. Honours Retry-After (RFC 7231 int +
HTTP-date), exponential backoff on 5xx, fail-fast on TLS/401/403.
Adds C11Config block, three FDR kinds (tile.queued, tile.rejected,
batch.complete), and the build_tile_uploader composition-root factory.
Cross-component access to c6 stays Protocol-cut (AZ-507 / AZ-270).
Tests: 17 new unit tests covering AC-1..AC-14 plus throughput NFR; AZ-272
schema fixtures for the three new FDR kinds. Full unit suite: 1404 passed.

Batch 38 (cycle 1) lands the two upload-side prerequisites the
upcoming AZ-319 TileUploader needs to authenticate per-flight
sessions against the parent suite's D-PROJ-2 ingest contract.
AZ-317 FlightStateGate:
- confirm_on_ground() defence-in-depth gate atop ADR-004 process
isolation; fail-closed for UNKNOWN, IN_FLIGHT, TAKING_OFF,
LANDING, and source-failure (mapped to UNKNOWN with original
exception preserved on __cause__).
- ERROR log on refusal, INFO log on pass, single source call per
invocation (no polling, no retry).
AZ-318 PerFlightKeyManager:
- Per-flight ephemeral Ed25519 keypair via the project-pinned
cryptography library; sign(payload) -> 64-byte Ed25519 signature.
- Best-effort zeroisation of a project-controlled bytearray mirror
on end_session; OpenSSL-side buffer freed via dropped reference.
- __del__ safety net with WARN log if end_session was missed.
- start_session emits FDR kind=c11.upload.session.key.public so the
safety officer can correlate flights with key fingerprints.
- record_signature_rejection emits FDR + ERROR log on parent-suite
ingest rejection (security-critical, never silently dropped).
Shared C11 plumbing:
- TileManagerError parent + 3 subclasses (FlightStateNotOnGroundError,
SessionNotActiveError, SignatureRejectedError envelope).
- FlightStateSignal (str, Enum) and PublicKeyFingerprint DTOs.
- FlightStateSource Protocol on c11_tile_manager.interface.
- runtime_root.c11_factory factories for both new services.
- Two new FDR kinds registered in fdr_client.records central
KNOWN_PAYLOAD_KEYS; AZ-272 schema-roundtrip fixtures added in
lockstep so the central test stays green.
Tests: 26 new + 2 fixture additions; full suite 1384 passed, 80
skipped (documented Docker / Tier-2 / CUDA gates).
Code review: PASS_WITH_WARNINGS — 2 Low findings documented in
_docs/03_implementation/reviews/batch_38_review.md (dev-host vs
operator-workstation perf bound; spec text named StrEnum but
project pins Python 3.10).

Implements the public top-level F1 build orchestrator for E-C10 per
contract v1.1.0. Composes EngineCompiler (AZ-321), DescriptorBatcher
(AZ-322), and ManifestBuilder (AZ-323) into a single idempotent
operation guarded by a fcntl-backed cache_root/.c10.lock and a
post-build coverage walk.
Adds:
- CacheProvisionerImpl + FilelockFileLockFactory (provisioner.py)
- BuildRequest/BuildReport/BuildOutcome/SectorClassification DTOs +
FileLockFactory Protocol + replaced placeholder CacheProvisioner
Protocol with v1.1.0 surface (interface.py)
- C10ProvisionerConfig wired into C10ProvisioningConfig (config.py)
- BuildLockHeldError + ManifestCoverageError (errors.py)
- build_cache_provisioner composition root (c10_factory.py)
- 18 tests covering AC-1..AC-16 + NFR-perf-coverage-walk
- filelock>=3.13,<4.0 (single new third-party dep)
Idempotence (CP-INV-1) reuses AZ-323's _compute_manifest_hash /
_aggregate_tile_hash so the build-identity decision agrees byte-for-
byte with the Manifest's recorded manifest_hash. Coverage rollback
uses a .prev rename snapshot. Diagnostic compile_engines_for_corpus
is lock-free per AC-10.

Production-default DescriptorIndex strategy backed by the faiss-cpu
PyPI wheel (>=1.7,<2.0). Implements the AZ-303 Protocol surface end
to end: HNSW32 + IndexIDMap2 search, atomic three-file rebuild
(.index + .sha256 sidecar + .meta.json), triple-consistency load
check, mmap-backed reads with IO_FLAG_MMAP|IO_FLAG_READ_ONLY, optional
warm-up query at construction, FAISS RuntimeError rewrap to
IndexUnavailableError / IndexBuildError, and FaissDescriptorIndex.from_config
classmethod wired into runtime_root.storage_factory.
The original spec required a custom pybind11 wrapper over a vendored
FAISS HEAD; the user opted for the upstream faiss-cpu wheel after
research fact #92 confirmed ARM64 wheel availability for Jetson and
the existing pyproject.toml already pinned faiss-cpu. cpp/faiss_index/
placeholder removed; BUILD_FAISS_INDEX flag retained as a
runtime/factory gate (no native target). Spec rewritten end-to-end and
archived to _docs/02_tasks/done/.
C6TileCacheConfig extended with faiss_index_path and
faiss_warmup_query_path fields. tests/conftest.py sets
KMP_DUPLICATE_LIB_OK=TRUE to remediate the macOS faiss/torch libomp
duplicate-load abort during pytest (no-op on CI Linux). 21 new tests
cover AC-1..12 + 2 NFRs + from_config smoke; AZ-303 protocol-conformance
fake updated with from_config classmethod.
Tests: 124/124 c6_tile_cache pass; 1334 project-wide pass; 1
pre-existing OKVIS2 submodule failure unrelated.

AZ-507: codify cross-component import rule. Added
_types/inference_errors.py shim re-exporting EngineBuildError +
CalibrationCacheError from c7_inference; narrowed C10
EngineCompiler's except Exception to the two typed errors so unknown
exceptions propagate (AC-3). Rewrote module-layout.md "Imports from"
sections for 9 components + added Rule 9; appended an
architecture.md ADR-009 note explaining why components must go
through _types/*.
AZ-323: ManifestBuilder + Ed25519ManifestSigner. Canonical JSON via
orjson OPT_SORT_KEYS+OPT_INDENT_2, atomic-write Manifest.json + sha
sidecar + .sig via AZ-280, operator-key fingerprint allowlist gate
(C10-ST-01), ADR-010 takeoff_origin + flight_id baked into Manifest
AND manifest_hash so re-planned routes change the cache identity
(AC-15/AC-16). 20 unit tests cover all 16 ACs.
AZ-324: ManifestVerifierImpl. Fail-closed Steps A-D: Manifest.json
sidecar self-hash, Ed25519 trust-key set, schema parse with
absolute/.. path rejection + takeoff_origin in-bbox check, stream
SHA-256 per artifact with multi-failure accumulation. Operator mode
re-derives tiles_coverage_sha256 from C6; airborne mode trusts the
signed aggregate. 19 unit tests cover all 17 ACs.
Composition root: c10_factory.build_manifest_builder +
build_manifest_verifier + c6_tile_metadata_store_to_tiles_query
adapter (the one place that legitimately imports both C6 and C10
without violating the AZ-270 lint).
Dependency: pinned cryptography>=43.0,<46.0 in pyproject.toml.
Tests: 1300 passed, 80 skipped (env-only), ruff clean for all
AZ-323/324 files.
AZ-306 (FAISS) intentionally deferred to batch 35 — needs C++
pybind11 toolchain not present in this environment.

Open two ~2-point hygiene PBIs surfaced by
_docs/03_implementation/cumulative_review_batches_31-33_cycle1_report.md:
- AZ-507 (parent AZ-246 / E-CC-CONF) — align module-layout.md
cross-component import rules with the AZ-270 lint test. Resolves the
doc-vs-lint contradiction surfaced on AZ-321 by tightening the doc
(option (a) from the review) + hoisting EngineBuildError /
CalibrationCacheError to _types/inference_errors.py.
- AZ-508 (parent AZ-264 / E-CC-HELPERS) — consolidate 5 identical
_iso_ts_now() one-liners across c6_tile_cache + c7_inference into a
single Layer-1 helper at helpers/iso_timestamps.py.
Dependencies table headers bumped: 142 -> 144 tasks, 478 -> 482 points
(product 345 -> 349). State file's pause-point detail cleared; next
sub_step is the implement skill's Step 3 (compute next batch) for
batch 34.

Land the C10 per-model engine compile + cache-reuse orchestrator.
`EngineCompiler.compile_engines_for_corpus(request)` walks the
corpus, computes the canonical engine filename via AZ-281
`EngineFilenameSchema.build`, and either reuses the cached binary
(cache hit, AZ-280 `Sha256Sidecar.verify` returns True) or delegates
to the AZ-297 `compile_engine` on the injected runtime (cache miss;
the runtime owns the write path). Returns one `EngineCompileResult`
per backbone carrying the canonical `EngineCacheEntry`, outcome
(BUILT / REUSED), and `compile_duration_s` (None on reuse).
Hardware-tied reuse (D-C10-6 / D-C10-7) falls out of the filename
schema — a host change rebuilds at the new path and leaves the old
files untouched (AC-4).
Design corrections vs. the task spec body:
- The spec proposed a c10-local `EngineCacheEntry` carrying outcome
and duration; that name is already taken by the AZ-297 canonical
DTO. The wrapper is renamed `EngineCompileResult`; the canonical
shape wins.
- The spec called `InferenceRuntime.host_info()`, which is not in
the AZ-297 Protocol. `HostCapabilities` is threaded through
`EngineCompileRequest` instead so the composition root owns host
probing and the compiler stays decoupled.
- The c10 layer cannot import `components.c7_inference` (arch rule
`test_az270_compose_root.test_ac6`). `engine_compiler.py` defines
`CompileEngineCallable` — a structural Protocol cut of
`InferenceRuntime` exposing only `compile_engine` — and catches
broad `Exception` (re-raising preserves the original type;
`error_class` is recorded in the ERROR log payload).
Production
- engine_compiler.py: `CompileOutcome` enum, `BackboneSpec`,
`EngineCompileRequest`, `EngineCompileResult`,
`EngineCompileSummary` DTOs; `CompileEngineCallable` Protocol;
`EngineCompiler` with the single public method.
- config.py: `BackboneConfig` + `C10ProvisioningConfig`
(`workspace_mb` default 4 GiB to match C7 NFT-LIM-01); validate
positive shape dims and duplicate model_name detection in
`__post_init__`.
- runtime_root/c10_factory.py: `build_engine_compiler(config)` wires
the existing `build_inference_runtime` factory through;
`build_backbone_specs(config)` materialises the `BackboneSpec`
tuple from the config block.
- components/c10_provisioning/__init__.py: re-exports the AZ-321
surface and registers the new config block.
Tests
- test_engine_compiler.py: covers AC-1..AC-10 + missing-sidecar
sibling case for AC-5. Tier-1 via fake runtime that writes through
the REAL `Sha256Sidecar.write_atomic_and_sidecar`. Tier-2
placeholders for the cache-hit p99 NFR (200 MB engine sweep) and
kill-during-compile atomic-write NFR.
Docs
- module-layout.md: c10_provisioning Per-Component Mapping lists the
new internal modules (engine_compiler.py, config.py), the
composition-root c10_factory.py, the AZ-321 public re-export
surface, and the registered config block.
- batch_33_cycle1_report.md + reviews/batch_33_review.md:
PASS_WITH_WARNINGS (4 Low findings accepted).
Tests run: c10_provisioning 13 passing + 2 Tier-2 skips; combined
unit suite (excluding pending components) 543 passing, 21

Land the fallback InferenceRuntime strategy that satisfies C7-IT-05:
when the TRT-direct path (AZ-298) cannot deserialise a cached engine
or when the operator explicitly selects ORT, the system stays in the
air at degraded latency rather than dropping the request. Conforms to
the AZ-297 Protocol; current_runtime_label() == "onnx_trt_ep".
Production
- onnx_trt_ep_runtime.py: compile_engine is a no-op returning an
EngineCacheEntry pointing at the source .onnx; deserialize_engine
is gate-first for .engine entries and gate-skip for .onnx, builds
an ORT InferenceSession with the provider list
[TensorrtExecutionProvider, CUDAExecutionProvider,
CPUExecutionProvider], stages cached engines into the ORT TRT EP
cache directory via symlink-or-copy, warms up with one session.run
after construction, and honours config.inference.ort_disallow_cpu_
fallback by raising EngineDeserializeError when the active provider
resolves to CPU; infer emits a one-shot c7.fallback_to_onnx_trt_ep
WARN log plus gcs_alert callback on first call when is_fallback=
True; release_engine is idempotent. _build_provider_args is the
single point that pins TRT EP option-key names (Risk-3) and caps
trt_max_workspace_size at gpu_memory_budget_bytes // 4 (AC-8).
- config.py: adds ort_trt_cache_dir (validated non-empty) and
ort_disallow_cpu_fallback to C7InferenceConfig.
- fdr_client/records.py: adds c7.fallback_to_onnx_trt_ep and
c7.cpu_fallback FDR record kinds.
Tests
- test_onnx_trt_ep_runtime.py: covers AC-1..AC-8 + Risk-2 CPU-fallback
alert + Risk-3 option-key pin + NFR-reliability error rewrap; Tier-1
via fake ORT session; Tier-2 placeholders skip on macOS dev for
numerical FP16 comparison and session-creation perf NFR.
- test_protocol_conformance.py: drops onnx_trt_ep from the missing-
module parametrize now that the module ships.
- test_az272_fdr_record_schema.py: extends per-kind fixture builder
to cover the two new C7 FDR kinds in the roundtrip / schema-version
AC tests.
Docs
- module-layout.md: replaces the pending onnx_trt_runtime row with
the shipped onnx_trt_ep_runtime row + capabilities list.
- batch_32_cycle1_report.md + reviews/batch_32_review.md: full batch
+ self-review (PASS_WITH_WARNINGS, 4 Low findings accepted).
Tests run: c7_inference 139 passing + 17 Tier-2 skips; combined unit
suite (excluding pending components) 529 passing, 19 env-skipped.

Implement the production-default InferenceRuntime strategy on JetPack
6.2 + TensorRT 10.3 (per D-C7-9). The runtime owns the full TRT
lifecycle: compile_engine via the Polygraphy + trtexec + IBuilderConfig
hybrid (FP16 / INT8 / Mixed precision), deserialize_engine with
EngineGate-first ordering and a pre-allocation GPU memory budget gate,
infer via H2D -> enqueueV3 -> D2H -> stream sync on the owned CUDA
stream, idempotent release_engine, and an injected
ThermalStatePublisher delegation for thermal_state.
INT8 calibration cache trust (D-C10-6, AC-2/3/4) is enforced by a
.calib_cache.sha256 file-integrity sidecar (AZ-280) plus a new
.calib_cache.dataset_sha256 sidecar that records the dataset content
hash at compile time; reuse only when both agree, rebuild silently on
dataset hash mismatch, raise CalibrationCacheError on corrupt sidecar
(never silently overwritten).
GPU memory budget (NFT-LIM-01, default 4 GiB) is checked BEFORE any
TRT call beyond the gate (AC-6); a pre-allocation refusal raises
OutOfMemoryError and leaves the resident state unchanged.
TensorRT 10.3 / Polygraphy / PyCUDA are lazy-imported inside the
methods that need them so the module loads cleanly on Tier-0 hosts.
A standalone CLI entry (python -m
gps_denied_onboard.components.c7_inference.tensorrt_runtime compile
<onnx> <build_config.json>) is wired for C10 CacheProvisioner
(AZ-321) to invoke pre-flight without holding a runtime instance.
C7InferenceConfig gains gpu_memory_budget_bytes (default 4 GiB) and
trtexec_timeout_s (default 600 s, Risk 4 mitigation), both validated
in __post_init__.
Tests: 26 active + 6 Tier-2-gated skips; AC-1 / AC-3 / AC-4 / AC-5
/ AC-6 / AC-7 / AC-10 + NFR-reliability fully covered on Tier-1
via fake CUDA / TRT modules; AC-2 / AC-8 / AC-9 / NFR-perf-deserialize
placeholders skip with prerequisite reason and live in the AZ-298
Tier-2 microbench harness. Code review verdict
PASS_WITH_WARNINGS (1 Medium hot-path hoist fix auto-applied).

CacheBudgetEnforcer.reserve_headroom(needed_bytes) returns immediately
when total_disk_bytes() + needed_bytes <= budget, otherwise iterates
lru_candidates in eviction_batch_size batches, deletes via delete_tile,
emits one INFO log per evicted tile (c6.evicted) and one FDR record per
eviction batch (c6.eviction_batch, evicted_tile_ids capped to 5).
Raises CacheBudgetExhaustedError AFTER a full sweep if the budget
cannot be met. BudgetEnforcedTileStore decorates a TileStore so the
policy stays separable from PostgresFilesystemStore. Composition root
in storage_factory.build_tile_store wires the wrapper unconditionally.
PostgresFilesystemStore now accepts lru_clock: Clock | None = None;
when set, read_tile_pixels calls record_lru_access(tile_id, now) so
eviction picks the right LRU candidates. Production wiring injects
WallClock(); AZ-305 unit tests still construct without the clock and
keep their pass-through semantics. Contract tile_store.md bumped to
v1.1.0 to add CacheBudgetExhaustedError to the TileCacheError family;
shared FDR schema bumped to v1.3.0 for the new c6.eviction_batch kind.

Replaces the AZ-305 pass-through _evaluate_freshness hook with the
production FreshnessGate. Loads tile_freshness_rules + sector
classifications once at construction, builds an rtree index, and on
every evaluate() either returns metadata unchanged (FRESH), stamps
freshness_label=DOWNGRADED (stable_rear + stale), or raises
FreshnessRejectionError carrying tile_id / age_seconds /
classification / rule diagnostics (active_conflict + stale).
Constructed inside PostgresFilesystemStore.from_config; the public
storage_factory signature is preserved so AZ-305 unit tests still
build the store with freshness_gate=None for the pass-through path.
FDR schema bumped to v1.2.0: adds c6.freshness.rejected and
c6.freshness.downgraded kinds (non-breaking; v1.1 readers route them
opaquely). Operator CLI `python -m c6_tile_cache.freshness_gate
explain` dry-runs the decision for a (lat, lon, capture_ts).
Adjacent hygiene: c6_tile_cache.tools._dump_tile now passes
os.environ to load_config (AZ-305 regression — load_config requires
the env mapping).

Adds the production PostgresFilesystemStore implementing both protocols
in a single class. Filesystem-backed JPEG I/O (atomic sidecar write,
read-only mmap) + Postgres-backed metadata (spatial bbox, LRU, voting,
upload bookkeeping). Wires composition via `from_config` classmethod.
Key behaviors:
- AC-3 strict reading: INSERT runs first inside an open transaction;
duplicate-key collisions raise `TileMetadataError` BEFORE any byte is
written, leaving the original file + sidecar byte-identical. Atomic
sidecar write happens inside the same transaction; commit closes it.
Comp-delete remains as a safety net for the rare commit-after-write
failure path.
- AC-2 content-hash gate runs before any I/O.
- Construction performs an orphan-file reconciliation scan and emits an
INFO `c6.store.construct` log with steady-state stats.
Adds `c6.write` and `c6.write_failed` FDR record kinds (schema v1.1.0,
forward-compatible) and a thin operator CLI at
`c6_tile_cache.tools dump` for inspection.
Dependencies: adds `psycopg-pool>=3.2,<4.0` for the connection pool used
on the F3 read-hot path.
Tests: 25 new tests for c6_tile_cache cover AC-1..AC-15 plus
MmapTilePixelHandle + helper round-trips. Full Tier-2 unit suite passes
(1215 passed, 8 skipped, 1 pre-existing unrelated failure
`test_ac8_read_host_tuple_on_jetson` — missing `pynvml` on macOS,
Jetson-only).

Strictly additive Alembic migration on the AZ-263 baseline (data_model
.md § 6.1 / § 6.3): six new tiles columns (tile_uuid UNIQUE,
location_hash, content_sha256, disk_bytes, accessed_at, uploaded_at),
four new btree indices, one UNIQUE expression index over the
COALESCE-zero-uuid natural key, CHECK widening of
ck_tiles_freshness_status to the AZ-263 + AZ-303 vocabulary UNION,
four NULLable bbox columns on sector_classifications, and a new
tile_freshness_rules table seeded with the two default thresholds.
Pinned UUIDv5 namespace (TILE_NAMESPACE_UUID =
5b8d0c2e-1a4f-4b3a-8c9d-e7f6a3b2c1d0) + derive_tile_id /
derive_location_hash helpers cross-coordinated with
satellite-provider. Migration runner apply_migrations(config) drives
Alembic command.upgrade("head") against the AZ-263 env with one
retry on PG SQLSTATE 40001 and structured INFO logs on apply / no-op.
Contract bump tile_metadata_store.md v1.1.0 -> v1.2.0 adds
TileMetadata.location_hash: UUID | None = None (non-breaking).
module-layout.md updated so c6_tile_cache explicitly Owns
db/migrations/**.
Tier-1 tests: UUIDv5 determinism + locked vectors + DSN resolution +
retry mocked DBAPIError -> 1180 passed, 32 skipped. Tier-2 docker
schema tests gated by @pytest.mark.docker run against the existing
docker-compose.test.yml db service.

- Changed autodev state to reflect the transition from batch 26 to batch 27, updating the phase and details for the compute-batch step.
- Incremented the version of the tile metadata store from 1.0.0 to 1.1.0, refining the uniqueness invariant to use a natural key that includes flight_id, allowing coexistence of multiple rows for the same tile from different flights.
- Updated the last modified date in the tile metadata store documentation to reflect recent changes.

Implements AZ-297 InferenceRuntime's thermal_state() side: a singleton
background-thread publisher that polls jtop (preferred) or pynvml
(fallback) at config.thermal_poll_hz, stores an atomic ThermalState
snapshot, and emits c7.thermal_transition FDR records on every throttle
flip with a WARN log on entry and an INFO log on exit. Default-safe on
TelemetryUnavailableError per Invariant I-6 with a 1-Hz rate-limited
WARN.
Sources return a raw ThermalReading; the publisher stamps measured_at_ns
via its injected Clock so _JtopSource / _PynvmlSource stay clean of
direct time.* calls (Invariant 2). _poll_once is the deterministic test
seam — start() spawns the production thread.
- c7.thermal_transition registered in fdr_client.records KNOWN_PAYLOAD_KEYS
- [telemetry] optional dep group (jetson-stats, pynvml) added to pyproject
- 14 unit tests (AC-1..AC-6, AC-8, NFR-default-safe, structural)
green; AC-7 / AC-1 microbench / NFR-perf-poll Tier-2 deferred
- full unit suite: 1140 passed, 11 expected Tier-2/CUDA skips

AZ-301 takeoff-side validator every InferenceRuntime strategy calls
before deserialize_engine. Five-step deterministic refusal pipeline,
in order:
1. filename schema parse -> EngineSchemaMismatchError(reason=...)
2. schema tuple match -> EngineSchemaMismatchError(expected,got)
3. sidecar present -> EngineSidecarMissingError
4. sidecar trust -> EngineHashMismatchError(stage=sidecar)
5. manifest match -> EngineHashMismatchError(stage=manifest)
Refusal order is part of the public contract (AC-7 verifies a
fixture that is BOTH schema-mismatched AND missing-sidecar refuses
at step 1).
Production code (new):
- components/c7_inference/engine_gate.py -- EngineGate, HostTuple,
read_host_tuple (Jetson: pynvml + /etc/nv_tegra_release +
tensorrt.__version__; raises RuntimeError on Tier-1)
- components/c7_inference/manifest.py -- DeploymentManifest,
ManifestReader, ManifestReaderProtocol. Risk-2 enforced at the
type level: __getitem__ raises EngineHashMismatchError on
missing key, NEVER KeyError, so the gate cannot silently pass
- components/c7_inference/__init__.py -- re-exports the new
public surface
Tests (new): tests/unit/c7_inference/test_engine_gate.py covers
AC-1..AC-7 + NFR-reliability-no-write + manifest reader + refusal
log emission. 14 tests unconditional + AC-8 Tier-2 skip (needs
real NVML + L4T release file + tensorrt binding).
Three task-spec -> as-built deltas documented in
_docs/02_tasks/done/AZ-301_c7_engine_gate.md Implementation Notes:
1. HostTuple lives in engine_gate.py (the only consumer);
re-exported from package __init__.py.
2. read_host_tuple takes precision as a keyword argument — three
of four fields come from the host, precision is engine-build
metadata supplied by the caller.
3. AC-8 is Tier-2-only; AC-1..AC-7 + NFR-reliability + extras
run on every CI host.
Risk-2 (manifest reader silently treats missing entry as pass):
DeploymentManifest.__getitem__ raises EngineHashMismatchError with
"missing manifest entry for {path}" — covered by
test_manifest_missing_entry_raises_hash_mismatch.
NFR-perf-validate (p99 <= 50 ms): tier-2 only — a real 500 MB
engine streaming sha256 cannot be benchmarked on Tier-1 fixtures.
AZ-302 (ThermalStatePublisher) + AZ-304 (C6 Postgres schema)
deferred to batches 26 / 27 to keep the 1-task batch cadence and
isolate their respective env / testcontainer surface areas.
Suite: 1134 passed / 11 skipped. No regressions outside the new
files.

Python facade (`Okvis2Strategy`) is production-quality and satisfies
AZ-331's `VioStrategy` protocol; full AC-1..10 coverage with
AC-9 + NFR-perf marked `tier2`. The C++ pybind11 binding compiles
and loads but throws `OkvisFatalException("estimator not yet wired")`
on first `add_frame` — the `okvis::ThreadedKFVio` wiring is a tier2
follow-up the Step-15 Product Completeness Gate is expected to track
as a remediation task.
Resolved contradictions:
* Constructor signature aligned with the AZ-331 factory: `(config, *,
fdr_client, clock=None)`. Calibration / preintegrator / logger
built internally from config. No churn on AZ-331.
* IMU substrate: OKVIS2 owns its internal estimator IMU integration;
the AZ-276 `ImuPreintegrator` is a separate substrate consumed by
E-C5's fusion graph. Single source of truth lives at the sample
stream, not the integrator instance.
* FDR API: `FdrClient.enqueue(record)` with new `vio.health` kind
added to AZ-272 `KNOWN_PAYLOAD_KEYS`.
CI matrix forces `-DBUILD_OKVIS2=OFF` until the tier2 wiring task
brings Ceres / SuiteSparse / OKVIS2 vendored submodules into the
Linux build.
Files: 17 added/modified across `c1_vio/`, `fdr_client/records.py`,
`cpp/okvis2/CMakeLists.txt`, CI workflow, AZ-332 task spec
(implementation-notes section), batch 23 report.
Tests: 17 new (15 tier1 + 2 tier2). Full Tier-1 suite: 1109 pass,
2 skipped (env), 2 deselected (tier2). No regressions.

Implements the production-default ReRankStrategy: K=10 → N=3 by
single-pair LightGlue inlier count, with strict drop-and-continue
(INV-8) on per-candidate TileFetch / backbone / zero-inlier failures
and RerankAllCandidatesFailedError on zero survivors. Composition
root injects the shared LightGlueRuntime + Clock + the new
FeatureExtractor helper (an L1 placeholder OpenCvOrbExtractor that
unblocks AZ-343 and future C3 strategies — task scope expansion).
Architectural notes:
- Cross-component imports stay banned; tile_store types as `object`
and the C6 TileCacheError family is duck-typed by class module
prefix (same workaround AZ-348 adopted for c7_inference; proper
fix is to relocate TileCacheError to _types/ in a follow-up).
- Clock injection follows the replay contract (AZ-398 Invariant 2);
reranked_at is sourced from clock.monotonic_ns().
- AZ-342 factory grew `feature_extractor` + `clock` + `fdr_client`
parameters; existing AZ-342 conformance tests updated.
Tests: 19 new AC-1..AC-12 + mixed-failure scenarios in
test_inlier_count_reranker.py; existing AZ-342 suite (26) still
green. Full repo sweep 1093 passed / 2 skipped (cmake/actionlint
not on PATH).

Defines the public `ConditionalRefiner` Protocol (PEP 544
@runtime_checkable, two methods: `refine_if_needed` +
`was_invoked`), extends `MatchResult` in-place with two
default-valued refinement fields (`refinement_label`,
`refinement_added_latency_ms`), defines the `RefinerError` family
(`RefinerBackboneError`, `RefinerConfigError`), and ships the
trivial `PassthroughRefiner` reference impl.
Both refiner strategies are linked unconditionally — no
`BUILD_REFINER_*` flag (NOT ADR-002 territory). Runtime selection
only per ADR-001. `PassthroughRefiner` returns the input
`MatchResult` by reference (bit-identical correspondences per
contract INV-5) and always reports `was_invoked() is False`.
Documentation: renames `module-layout.md` `c3_5_adhop` Public API
symbol from `AdHoPRefinementStrategy` to `ConditionalRefiner`
(AC-14) so the doc agrees with `description.md` and the contract.
AC-9 (single-thread binding) deferred to AZ-270 runtime-root
composition, mirroring AZ-336 / AZ-342 / AZ-344 Risk-4 precedent.
AC-7 for the `"adhop"` strategy stops at `ModuleNotFoundError`
because the AdHoP backbone is owned by AZ-349. All other ACs +
NFRs covered by 36 new conformance tests.
Architectural note: `PassthroughRefiner.inference_runtime` is
typed as `object` because the L3→L3 import ban
(`test_az270_compose_root`) forbids c3_5_adhop from importing
c7_inference; the runtime-root factory narrows the type at
construction time.

Defines the public `CrossDomainMatcher` Protocol (PEP 544
@runtime_checkable, two methods: `match` + `health_snapshot`),
the three frozen+slotted DTOs (`CandidateMatchSet`, `MatchResult`,
`MatcherHealth`) in the L1 `_types/matcher.py` layer, the
`MatcherError` family (`MatcherBackboneError`,
`InsufficientInliersError`), and the composition-root
`build_matcher_strategy` factory with lazy-import +
`BUILD_MATCHER_<variant>` gating per ADR-002.
`RollingHealthWindow` accumulator (60 s, amortised O(1) update,
strict O(1) snapshot) is constructed by the factory and injected
into every concrete matcher so all backbones share window
semantics; this is what backs C5's spoof-promotion gate.
Legacy placeholder `MatchResult` removed from `_types/matching.py`;
import-only consumers (`c4_pose.interface`, `c3_5_adhop.interface`)
repointed at the new `_types/matcher.py` home — zero behavioural
change to those components.
AC-9 (single-thread binding) and AC-10 (LightGlueRuntime
identity-share with C2.5) deferred to AZ-270 runtime-root
composition, mirroring the AZ-342 Risk-4 escape clause. All other
ACs + NFRs covered by 70 new conformance tests.

Foundational scaffolding for the InlierCountReRanker (AZ-343) and
the future C3 CrossDomainMatcher consumer (AZ-344). No concrete
re-ranker is implemented here.
* ReRankStrategy Protocol (single rerank(frame, vpr_result, n,
calibration) -> RerankResult method) with all 8 invariants in the
docstring — notably INV-8 drop-and-continue (per-candidate failure
NEVER propagates unless every candidate fails).
* DTOs moved to L1 _types/rerank.py — RerankCandidate, RerankResult;
frozen+slots; tuple-not-list for RerankResult.candidates; tile_id
encoded as (zoom_level, lat, lon) tuple to keep _types/ free of any
c6_tile_cache (L3) import per module-layout.md.
* Error family: RerankError + RerankBackboneError +
RerankAllCandidatesFailedError. Only RerankAllCandidatesFailedError
escapes rerank(); RerankBackboneError is caught inside the per-
candidate loop, logged ERROR, FDR-stamped, candidate dropped.
* C2_5RerankConfig (strategy enum default "inlier_count", top_n int
default 3) with strict validation at load; registered into
Config.components on c2_5_rerank import.
* build_rerank_strategy(config, *, tile_store, lightglue_runtime)
factory: 1-strategy resolution table, lazy import,
BUILD_RERANK_<variant> gate, ImportError → StrategyNotAvailableError
mapping. The shared LightGlueRuntime is constructor-injected
(R14 fix: neither C2.5 nor C3 owns its lifecycle).
Renamed the Protocol from the existing stub "RerankStrategy" to
"ReRankStrategy" to match the contract; updated module-layout.md.
Removed the legacy RerankResult shape from _types/vpr.py — the
v1.0.0 shape lives in _types/rerank.py.
Excluded per task spec:
* Concrete InlierCountReRanker (AZ-343).
* C3 matcher protocol task (AZ-344, next in batch).
* AC-9 single-thread binding + AC-10 LightGlueRuntime identity-share
between C2.5/C3 — deferred per task spec Risk 3 until the generic
compose_root thread-binding registry and the C3 factory both land.
Tests: AC-1..AC-8 + AC-11 + NFR-perf-factory in
tests/unit/c2_5_rerank/test_protocol_conformance.py. The legacy
smoke test is removed. Full sweep: 997 passed (one pre-existing
flake in test_az296_takeoff_abort, subprocess timing, unrelated to
this commit; passes in isolation).

Foundational scaffolding for every concrete C2 backbone (UltraVPR,
NetVLAD, MegaLoc, MixVPR, SelaVPR, EigenPlaces, SALAD — AZ-337..AZ-340)
and the C2.5 ReRanker consumer side. No backbone is implemented here.
* VprStrategy Protocol (embed_query / retrieve_topk / descriptor_dim)
+ BackbonePreprocessor C2-internal Protocol (NOT in Public API per
description.md § 6).
* DTOs in L1 _types/vpr.py — VprQuery, VprCandidate, VprResult; all
frozen + slots; tuple-not-list for VprResult.candidates so the
immutability invariant truly holds.
* Error family: VprError + VprBackboneError + VprPreprocessError +
IndexUnavailableError; same-named but namespace-distinct from
c6_tile_cache.IndexUnavailableError (the c2 family is the closed
envelope C5 / C2.5 consume; concrete strategies rewrap the C6 form).
* C2VprConfig (strategy enum + backbone_weights_path + faiss_index_path)
with strict validation at load; registered into Config.components on
c2_vpr import.
* build_vpr_strategy factory with 7-strategy resolution table, lazy
import, BUILD_VPR_<variant> gating, ImportError→
StrategyNotAvailableError mapping, and pre-flight descriptor_dim
match against DescriptorIndex.descriptor_dim() — mismatch fires
ConfigError at startup, NOT at first frame.
Contract change vs the v1.0.0 draft: factory takes descriptor_index:
DescriptorIndex (not tile_store: TileStore) because descriptor_dim()
lives on DescriptorIndex per C6's Public API. The contract markdown
is updated to match.
Architecture: VprCandidate.tile_id is a plain (zoom, lat, lon) tuple,
keeping _types/ (L1) free of any c6_tile_cache (L3) import per
module-layout.md. Consumers reconstruct TileId at the C6 boundary.
Excluded per task spec:
* Concrete backbones (AZ-337..AZ-340).
* FAISS HNSW retrieve wiring (AZ-341).
* DescriptorNormaliser helper (AZ-283, already shipped).
* AC-9 single-thread binding — deferred per task spec Risk 4 until the
generic compose_root thread-binding registry is in place (today
each factory owns its own, e.g. fc_factory).
Tests: 45 ACs + NFRs in tests/unit/c2_vpr/test_protocol_conformance.py
covering AC-1..AC-8, the error family, the config validation, the
factory NFR (p99 ≤ 50 ms). The legacy smoke test is removed. Full
sweep 973 passed, 2 skipped (CI-only cmake / actionlint).

Freezes the c1_vio Public API per
_docs/02_document/contracts/c1_vio/vio_strategy_protocol.md v1.0.0:
- VioStrategy Protocol (4 methods: process_frame, reset_to_warm_start,
health_snapshot, current_strategy_label) in
components/c1_vio/interface.py.
- DTOs (VioOutput, VioHealth, FeatureQuality, WarmStartPose) + VioState
enum in _types/nav.py — L1 placement so C5 + C13 consume them without
crossing the components.* boundary (AZ-270 AC-6). The new VioOutput
shape (frame_id: str, relative_pose_T: gtsam.Pose3,
pose_covariance_6x6, imu_bias, feature_quality, emitted_at_ns)
replaces the AZ-263 scaffolding in _types/vio.py, which is now
deleted.
- VioError family (VioInitializingError / VioDegradedError /
VioFatalError) in components/c1_vio/errors.py. Documented
rationale: the degraded-operation path returns a VioOutput with
inflated covariance + VioHealth.state=DEGRADED rather than raising
VioDegradedError — the error type exists only for the rare
degraded->fatal transition.
- C1VioConfig per-component config block (strategy enum,
lost_frame_threshold default 9, warm_start_max_frames default 5)
with constructor-time validation rejecting unknown strategy labels.
- StrategyNotAvailableError added to runtime_root/errors.py;
composition-time error distinct from the VioError family.
- Composition-root factory build_vio_strategy in
runtime_root/vio_factory.py with three BUILD_* gates (BUILD_OKVIS2,
BUILD_VINS_MONO, BUILD_KLT_RANSAC). Concrete strategy modules are
imported lazily via __import__ AFTER the flag check — Tier-0
workstation builds with the flag OFF MUST NOT load the strategy
module (Risk-2 / I-5; verifiable via sys.modules).
- 36 conformance tests cover all 9 ACs + NFR-perf-factory
(p99 build under 200 ms x 1000 calls) + NFR-reliability-error-family.
AC-8 introspects the contract file's Shape table and asserts method
parity against the runtime Protocol; AC-9 asserts the frame_id
annotation is 'str' (PEP-563 stringified).
C5 migration (consumers of the new VioOutput shape):
- gtsam_isam2_estimator.py + eskf_baseline.py: replaced
vio.timestamp -> vio.emitted_at_ns (drops _datetime_to_ns on the
VIO path), vio.pose_se3 -> vio.relative_pose_T (gtsam.Pose3 direct;
drops _pose_se3_to_gtsam / _pose_se3_to_array), vio.covariance_6x6
-> vio.pose_covariance_6x6 (rename).
- key_for_frame signature widened to UUID | int | str to accept the
new str frame_id.
- 4 C5 test files migrated to the new VioOutput shape with helper
fixtures producing ImuBias + FeatureQuality + str frame_id.
- c5_state/interface.py TYPE_CHECKING import path updated.
Bootstrap healthcheck + test_types_importable updated to drop the
deleted _types/vio module and pick up _types/inference (AZ-297) in
the same sweep.
Full unit-test sweep: 884 passed, 2 pre-existing environment skips

Freezes the c7_inference Public API per
_docs/02_document/contracts/c7_inference/inference_runtime_protocol.md
v1.0.0:
- InferenceRuntime Protocol (6 methods: compile_engine,
deserialize_engine, infer, release_engine, thermal_state,
current_runtime_label) in components/c7_inference/interface.py.
- DTOs (PrecisionMode enum, OptimizationProfile, BuildConfig,
EngineCacheEntry, EngineHandle opaque marker) in _types/inference.py
— placed at the L1 types layer so C10 can re-export EngineCacheEntry
without crossing the components.* boundary (AZ-270 AC-6).
- ThermalState DTO expanded in _types/thermal.py from the AZ-355
forward-declared stub to the AZ-297 contract shape (cpu/gpu temp,
thermal_throttle_active, measured_clock_mhz, measured_at_ns,
is_telemetry_available). Invariant I-6: when telemetry is
unavailable, throttle is False.
- Error family rooted at c7_inference.errors.RuntimeError (9 subtypes:
EngineBuildError, EngineDeserializeError, EngineHashMismatchError,
EngineSchemaMismatchError, EngineSidecarMissingError,
CalibrationCacheError, InferenceError, OutOfMemoryError,
TelemetryUnavailableError). RuntimeNotAvailableError stays in
runtime_root/errors.py — composition-time, outside the family.
- C7InferenceConfig per-component config block (runtime label,
thermal_poll_hz, engine_cache_dir) with constructor-time validation
rejecting unknown runtime labels.
- Composition-root factory build_inference_runtime in
runtime_root/inference_factory.py with three BUILD_* gates
(BUILD_TENSORRT_RUNTIME, BUILD_ONNX_TRT_EP_RUNTIME,
BUILD_PYTORCH_FP16_RUNTIME). Concrete strategy modules are imported
lazily via __import__ AFTER the flag check, so a Tier-0 build with
the flag OFF MUST NOT load the strategy module (AC-5 / I-5;
verifiable via sys.modules).
- 37 conformance tests cover all 8 ACs + NFR-perf-factory
(p99 build under 200 ms × 1000 calls) + NFR-reliability-error-family.
AC-8 introspects the contract file's Shape table and asserts method
parity against the runtime Protocol; also asserts all 9 error
subtypes are documented.
Retired the AZ-263 scaffolding EngineCacheEntry from _types/manifests.py
(replaced by the AZ-297 canonical shape in _types/inference.py); updated
the LightGlue-flavoured EngineHandle Protocol docstring in
_types/manifests.py to rationalize its intentional dual existence
with the C7 opaque EngineHandle (same name, different consumer-side
cut, mirroring the C4/C5 ISam2GraphHandle pattern).
Stale ThermalState.throttle docstring references in c4_pose/config.py,
c4_pose/interface.py, and _types/pose.py updated to
thermal_throttle_active.
Full unit-test sweep: 843 passed, 2 pre-existing environment skips

Freezes the c6_tile_cache Public API per
_docs/02_document/contracts/c6_tile_cache/{tile_store,tile_metadata_store,
descriptor_index}.md v1.0.0:
- Three runtime_checkable Protocols (TileStore 4-method, TileMetadataStore
9-method, DescriptorIndex 5-method) in components/c6_tile_cache/interface.py.
- Frozen DTOs + enums (TileId, TileMetadata, TileMetadataPersistent,
TileQualityMetadata, Bbox, SectorBoundary, HnswParams, IndexMetadata,
TileSource, FreshnessLabel, VotingStatus, SectorClassification) in
components/c6_tile_cache/_types.py. Constructor-time validation rejects
out-of-range zoom_level / lat / lon and inverted Bbox.
- TilePixelHandle ABC for read-only mmap access (Invariant I-4).
- TileCacheError family (6 subtypes) + IndexBuildError (deliberately
outside the family) in components/c6_tile_cache/errors.py.
- C6TileCacheConfig per-component config block, registered on package
import; validates known runtime labels at construction time.
- Composition-root factories build_tile_store / build_tile_metadata_store /
build_descriptor_index in runtime_root/storage_factory.py, with lazy
concrete-impl imports gated by BUILD_FAISS_INDEX (AC-5 / Risk 2:
no module-level FAISS import when the flag is OFF).
- RuntimeNotAvailableError defined in runtime_root/errors.py to be shared
with AZ-297 (composition-time error, distinct from per-component
runtime errors).
51 conformance tests cover all 10 ACs + NFR-perf-factory (p99 build_*
under 50 ms across 1000 calls) + NFR-reliability-error-family. AC-9
introspects each contract file's Shape table and asserts method
parity against the runtime Protocol.
Retired the AZ-263 scaffolding SectorClassification (dataclass) and
TileQualityMetadata from _types/tile.py since their canonical home is
now c6_tile_cache._types; Tile and TileRecord remain in _types/tile.py
until c3_matcher (AZ-344) and c11_tile_manager (AZ-316/319) retire
their interface stubs.

Add operator warm-start path to C5 StateEstimator Protocol and both
implementations (GtsamIsam2StateEstimator, EskfStateEstimator), plus
the third clause of the AZ-385 spoof-promotion gate.
- StateEstimator Protocol: set_takeoff_origin(origin, sigma_horiz_m,
sigma_vert_m) -> None.
- iSAM2: PriorFactorPose3 at origin with diagonal sigmas, single
isam2.update().
- ESKF: zero _nominal_pos, overwrite _P position block with sigma**2.
- SourceLabelStateMachine.process_gps_sample bounded-delta clause:
WgsConverter.horizontal_distance_m vs smoother estimate; reject
resets the dwell-time counter so AZ-385 cannot re-promote off bad
GPS.
- New EstimatorAlreadyStartedError (StateEstimatorConfigError
subclass) on late call after first add_*.
- C5StateConfig: spoof_promotion_bounded_delta_m=200,
default_takeoff_origin_sigma_horiz_m=5,
default_takeoff_origin_sigma_vert_m=10.
- New GpsSample DTO + WgsConverter.horizontal_distance_m helper.
- 4 new FDR kinds (cold_start_origin.{set,unavailable},

Implements the mandatory simple-baseline StateEstimator per AC-2.1a
engine-rule at C5 (IT-12 comparative study vs iSAM2). NumPy-only;
no GTSAM dependency so BUILD_STATE_ESKF=ON binaries ship without
GTSAM at all.
- 16-state error vector (pos 3 + vel 3 + rot 3 + ba 3 + bg 3 + dt 1)
over a textbook nominal-state / error-state ESKF split.
- add_fc_imu: full nonlinear IMU integration + linearised F P F^T + Q
covariance propagation per IMU sample.
- add_vio: simplified relative-pose update (snapshot-based; baseline
scope, documented).
- add_pose_anchor: absolute-pose update; integrates BOTH marginals and
jacobian modes (no skip — ESKF has no graph; AC-4).
- AC-9 divergence test: Mahalanobis r^T S^-1 r > 100 (10 sigma) on the
innovation covariance S = H P H^T + R.
- AC-5 SPD: Cholesky-positive enforcement on every emitted covariance;
non-SPD raises EstimatorFatalError and locks state to LOST.
- AC-6 honesty: smoothed_history entries carry smoothed=False; deviation
from C5 contract Invariant 7 documented in module + report.
- AC-7 / AC-10 BUILD_STATE_ESKF gating: works through existing factory
infra (state_factory._STATE_BUILD_FLAGS).
- AC-8: SourceLabelStateMachine + FallbackWatcher auto-wired eagerly
in __init__, same pattern as the iSAM2 estimator.
Tests: 20 new unit tests covering AC-1..AC-10 + robustness checks.
Full suite: 660 passed, 2 skipped (CI-only).
The AZ-386 Jira transition to Done is deferred (Atlassian MCP returned
'Not connected'); recorded in _docs/_process_leftovers/ for replay on
the next autodev invocation per the Leftovers Mechanism.

After every successful current_estimate(), emit one
c5.state.smoothed_history FDR record per newly-smoothed past
keyframe from IncrementalFixedLagSmoother. AC-4.5 (revised): the
smoothed stream goes ONLY to FDR; the C8 outbound forward-time
stream is unaffected.
Idempotency via _smoothed_fdr_watermark_s (smoother-native float
seconds); the same pose key is never emitted twice. Hook is
best-effort — internal failures log warnings but do not raise, so
a smoother divergence cannot contaminate the forward-time path.
Cross-task invariants documented:
- AC-3 ESKF no-op — AZ-386 installs an inert hook on the ESKF.
- AC-4 No C8 leak — enforced at the C8 boundary by AZ-261.
8 new unit tests against AC-1/2/5/6 + robustness (no-FDR-client,
marginals failure). Full suite: 640 passed, 2 skipped.
