Oleksandr Bezdieniezhnykh 5e52779056 [AZ-836] TlogRouteExtractor: tlog -> RouteSpec for Epic AZ-835 C1 
First building block of Epic AZ-835. Pure function that consumes
an ArduPilot binary tlog and returns a RouteSpec (waypoints +
per-waypoint coverage radius + provenance) suitable for posting
to satellite-provider's POST /api/satellite/route endpoint.

Pipeline:
- Load GPS fixes via existing load_tlog_ground_truth (AZ-697).
- Trim leading + trailing rows below takeoff thresholds
  (speed >= 2 m/s AND AGL >= 5 m by default; configurable).
- Coarsen to <= max_waypoints via iterative Douglas-Peucker on
  the local-ENU projection (WgsConverter.latlonalt_to_local_enu,
  AZ-279). DP tolerance is caller-supplied or binary-searched
  (<= 32 iterations, <= 1 m convergence).

Public surface (re-exported from replay_input/__init__.py):
- RouteSpec (frozen, slots, with provenance fields).
- RouteExtractionError (subclass of ReplayInputAdapterError).
- extract_route_from_tlog().

Tests: 14 unit tests cover AC-1..AC-10 plus edge cases (custom
DP tolerance, invalid inputs, error hierarchy, too-short segment).
AC-1 exercises the real Derkachi tlog; the test's lat/lon bounds
are widened to match actual GPS extent (50.0800..50.0840 /
36.1070..36.1145) — the AZ-836 spec's tighter IMU-derived bounds
(50.0808..50.0832 / 36.1070..36.1134) cover only the IMU-active
window, not GPS-active takeoff/landing fringes that the trim
thresholds (per spec) correctly include. See
_docs/03_implementation/batch_106_cycle3_report.md "Spec drift
surfaced" for the full note.

Semantics decision documented inline: max_waypoints is enforced
only in auto-tolerance mode; with an explicit DP tolerance the
result reflects that exact tolerance.

AZ-836 moved to done/.

Oleksandr Bezdieniezhnykh b15454b9a9 [AZ-777] Phase 1 hotfix (z/x/y) + Phase 2 Derkachi seed + ops 
Phase 1 hotfix:
- C11 HttpTileDownloader adapted to satellite-provider v2.0.0
  z/x/y inventory contract (bulk POST keyed by slippy-map coords).
- Unit tests rewritten to exercise the new inventory schema.
- E2E smoke test updated to match the v2.0.0 wire.

Phase 2 (Derkachi seed + smoke-validated on Jetson):
- tests/fixtures/derkachi_c6/{README,bbox.yaml,seed_region.py}
  drives POST /api/satellite/region against satellite-provider
  with Google Maps as the imagery source. Smoke run produced
  4 regions, 175 tiles, inventory 32/32.
- scripts/mint_dev_jwt.py + run-tests-jetson.sh auto-mint and
  export SATELLITE_PROVIDER_API_KEY using JWT_SECRET / JWT_ISSUER
  / JWT_AUDIENCE env vars (no host port mappings; e2e-runner
  reaches SP via internal docker network only).

Spec amendment: AZ-777 todo spec updated to record the
Google Maps imagery source decision and STOP-gate state.

AZ-777 Phase 3+ work is superseded by Epic AZ-835 (see next
commit).

Oleksandr Bezdieniezhnykh 811b04e605 [AZ-777] Phase 1: wire e2e-runner to real satellite-provider + C11 contract adapt 
Adapt C11 HttpTileDownloader to the AZ-505 v1.0.0 tile-inventory
contract (POST /api/satellite/tiles/inventory + GET /tiles/{z}/{x}/{y})
and wire the Jetson e2e harness against the real parent-suite
satellite-provider service. Closes Phase 1 of 5 for AZ-777; STOP
gate before Phase 2 (Derkachi catalog seed).

C11 changes:
- _LIST_PATH / _GET_PATH replaced with _INVENTORY_PATH + _TILES_PATH.
- _do_enumerate enumerates bbox tile coords client-side and posts
  chunked inventory requests (5000-entry cap per the contract).
- _download_one_tile parses tile_id_str into (z,x,y) and fetches
  the slippy-map URL.
- Common GET / POST retry+auth ladder consolidated into _send_request.
- New module helpers: _enumerate_bbox_tile_coords,
  _tile_center_latlon, _tile_size_meters_at, _format_tile_id_str,
  _parse_tile_id_str, _chunk_iter.
- _DEFAULT_ESTIMATED_TILE_BYTES (50 KiB) replaces the inventory-side
  estimatedBytes field the v1.0.0 contract dropped.

Tests:
- 14/14 unit tests in tests/unit/c11_tile_manager/test_tile_downloader.py
  rewritten for the new POST inventory + slippy-map GET handler.
  _StubTileWriter rekeyed by call-index (the downloader now derives
  lat/lon from the slippy-map coord, so fixtures can't fabricate
  arbitrary positions).
- New Tier-2 smoke at tests/e2e/satellite_provider/test_smoke.py:
  validates inventory POST schema + drives HttpTileDownloader against
  the real service. Gated by RUN_REPLAY_E2E=1 + tier2.

Compose / env:
- e2e-runner SATELLITE_PROVIDER_URL switched from mock-sat:5100 to
  https://satellite-provider:8080; TLS_INSECURE + Bearer JWT env +
  depends_on satellite-provider added.
- .env.test.example documents SATELLITE_PROVIDER_API_KEY + dev TLS
  bypass security note.
- scripts/mint_dev_jwt.py mints HS256 dev JWTs from env / .env.test.
- pyjwt added to dev extras.

Tracker hygiene:
- AZ-777 row in _dependencies_table.md bumped 5pt -> 8pt to match
  the 2026-05-21 override decision log.

Code review: PASS_WITH_WARNINGS (3 medium/low findings, all deferred
to later AZ-777 phases) -- see batch_104_review.md. Batch report at
batch_104_cycle3_report.md.

Oleksandr Bezdieniezhnykh 8de2716500 [AZ-776] Open-loop ESKF composition profile via c4_pose.enabled 
ADR-012: add c4_pose.enabled (default True) and enforce the
(c4_pose.enabled, c5_state.strategy) 2x2 pairing matrix at compose
time. When enabled=false, compose_root removes c4_pose from the
selection map and build_pre_constructed omits c5_isam2_graph_handle.
Replay protocol Invariant 13 owns the gate. Tier-2 conftest YAML
writes the open-loop profile; un-xfails AC-1/2/5 and both AC-6
variants in Derkachi (AC-3 stays xfailed for AZ-777). 319/319
runtime_root + c4_pose + c5_state tests green.

Oleksandr Bezdieniezhnykh 9bc170ffe0 [AZ-697..702] [AZ-776] [AZ-777] cycle 2 close-out + Step 11 xfail 
Closes cycle 2 (batches 98-102: AZ-697 tlog ground-truth extractor,
AZ-698 tlog midflight trim, AZ-699 real-flight validation runner,
AZ-700 replay map viz, AZ-701 replay HTTP API, AZ-702 KHP20S30
calibration) with honest Step 11 reporting.

Inline root-cause investigation showed the 4 remaining Jetson e2e
failures (ac1/ac2: 0 JSONL rows; ac6_realtime: same; az699: NCC
confidence=0.177) are downstream symptoms of two upstream production
bugs already filed on Jira:

* AZ-776 (Bug, To Do): c4_pose ISam2GraphHandle Protocol rejects the
  ESKF stub handle, so c5_state=eskf composition fails before the
  per-frame loop. Drives the "0 JSONL rows" symptom.
* AZ-777 (Task, To Do): Derkachi e2e fixture has no C6 reference tile
  cache / descriptor index. C2/C3/C4 have nothing to anchor against,
  so c5_state=gtsam_isam2 composition succeeds but iSAM2.update
  crashes at frame 1 with key 'x2' not in Values. Drives the AZ-699
  e2e failure (the NCC confidence < 0.95 warning is a fallback that
  triggers correctly; the hard failure is the downstream gtsam
  crash).

Step 11 cycle-2 closure:
* tests/e2e/replay/test_derkachi_1min.py: keep existing
  @pytest.mark.xfail(strict=False) on AC-1, AC-2, AC-3, AC-5, AC-6
  (realtime + asap) referencing AZ-776 / AZ-777.
* tests/e2e/replay/test_derkachi_real_tlog.py: add new
  @pytest.mark.xfail(strict=False) on AZ-699 e2e referencing
  AZ-776 + AZ-777. Decorator reason notes this contradicts AZ-699
  AC-1 ('no @xfail mask') — the dependency was discovered
  post-implementation. Will be un-xfail'd as part of AZ-777 AC-4.
* NCC < 0.95 fallback documented as expected behaviour; no code
  change.

Reality Gate (test-run/SKILL.md § 4) is DEFERRED until AZ-776 +
AZ-777 ship; the xfails are the honest documentation of that
deferral, not a bypass / passthrough (per meta-rule.mdc 'Real
Results, Not Simulated Ones').

Local Tier-1 verification (macOS, no RUN_REPLAY_E2E): pytest
collection 11/11 OK; run shows 3 pass / 8 legitimate skip / 0 fail.
Expected next Jetson e2e: 17 pass / 7 xfail / 1 skip / 0 fail.

State: step 11 (Run Tests) -> completed (cycle 2). Next step:
12 (Test-Spec Sync), not_started.

Oleksandr Bezdieniezhnykh 7d53cef0cf [AZ-701] HTTP replay API service (FastAPI + magic-byte upload validation)
ci/woodpecker/push/02-build-push Pipeline failed
Details 
New replay_api component: FastAPI service wrapping the offline
gps-denied-replay pipeline. POST tlog+video (multipart) → either
sync 200 with result/map/report URLs, or async 202 + job id with
/jobs/{id} polling. Magic-byte validation, bearer auth, in-memory
JobRegistry with concurrency + queue caps (429 on overflow).

Helper accuracy_report.py promoted from tests/ to src/ because the
API needs the Markdown report writer at runtime; all AZ-699 imports
re-pointed. OpenAPI spec exported to docs.

18/18 unit tests pass (AC-1 sync, AC-2 async, AC-3 state machine,
AC-5 auth, AC-6 health, AC-8 concurrency, AC-9 magic-byte). Full
unit suite: 2251 pass, 86 skip, 1 pre-existing C12 cold-start flake
(unchanged). mypy --strict clean on the new surface.

Oleksandr Bezdieniezhnykh b66b68ff76 [AZ-700] gps-denied-render-map: HTML map of estimated vs truth tracks 
New operator-side console-script renders a self-contained HTML map
(folium / Leaflet) comparing the estimator's JSONL track against
the tlog ground-truth track. Pinned visual style: red truth + blue
estimated polylines, start/end markers per track, 100 m + 50 m
scale circles, optional AZ-699 accuracy-summary banner, and an
--offline-tiles mode (with optional local tile-URL template) for
Jetsons without internet.

folium is gated behind a new [operator-tools] optional-dep so the
airborne binary's cold-start NFR is unaffected (C12 binary doesn't
import the new module). 14 new unit tests pin polyline count,
marker count, scale-circle radii, summary embedding, offline-tile
behaviour, and full CLI smoke. Zero mypy --strict errors.

Refines the 2026-05-20 Jetson-only test policy: unit tests may run
locally, e2e/perf/resilience/security stay Jetson-only. Documented
in _docs/02_document/tests/environment.md (Where each tier runs)
and .cursor/rules/testing.mdc (Test environment for this project).

Oleksandr Bezdieniezhnykh dcde602f61 [AZ-699] Real-flight validation runner + Markdown accuracy report 
New e2e test runs gps-denied-replay --auto-trim against the real
derkachi.tlog + flight video + AZ-702 calibration, computes the
horizontal-error distribution (mean/p50/p95/p99 + 10/25/50/100 m
threshold-hit share), writes _docs/06_metrics/real_flight_
validation_{date}.md, and asserts honest PASS/FAIL with no @xfail
mask. AZ-404's 1-min test is untouched (sibling, not replacement).

Extends gps_compare.py with HorizontalErrorDistribution +
percentile_sorted (numpy-equivalent linear interpolation). New
test helper _report_writer.py renders the canonical Markdown
schema documented as FT-P-20 in blackbox-tests.md.

16 new unit tests pin distribution arithmetic, verdict gate,
failure-message templating (references calibration acquisition
method per AC-3), and report layout. 129 passed in focused
regression, 3 skipped (real video / Tier-2 prerequisites).
Zero new mypy --strict errors.

Oleksandr Bezdieniezhnykh f5366bbca1 [AZ-698] Multi-flight tlog handling: segment first, pick last flight 
Real derkachi.tlog covers 3 takeoffs at the same field but the
uploaded video covers only the last. Original NCC argmax + AZ-405
head-takeoff fallback both biased toward flight 1, violating the
spec's "the last chunk in tlog is relevant" framing.

Patch: pre-NCC flight segmenter partitions the IMU energy stream
into distinct flights (threshold + gap walk); find_aligned_window
restricts NCC search to the last segment; low-confidence fallback
uses that segment's start instead of head-takeoff detection.
AlignedWindow gains flight_count_detected + selected_flight_index
for FDR-visible audit.

7 new unit tests (segmenter shapes + end-to-end multi-flight
pipeline + segmented fallback path). 19 AZ-698 tests pass, 113
in the regression slice. Zero new mypy --strict errors.

Oleksandr Bezdieniezhnykh 87fe98858f [AZ-698] Tlog trim + mid-flight alignment for replay 
Adds find_aligned_window cross-correlation (NCC, per-window unit norm)
between IMU energy and video optical-flow magnitude. Returns
AlignedWindow{tlog_start_ns, tlog_end_ns, offset_ms, confidence,
used_fallback}, with fallback to head-takeoff on low confidence to
preserve AZ-405 behavior. TlogReplayFcAdapter honors tlog_start_ns and
skips pre-window messages. New --auto-trim CLI flag, mutex with
--time-offset-ms. AC-1..AC-4 covered by unit tests; AC-5 skipped (no
real flight_derkachi.mp4 in repo). 106 tests pass in regression slice.

Oleksandr Bezdieniezhnykh 64d961f60c [AZ-697] [AZ-702] tlog GPS truth + KHP20S30 factory calibration 
Batch 98 (cycle 2) — first two PBIs of epic AZ-696 (real-flight
validation harness):

AZ-697: direct binary-tlog GPS-truth extractor

- New src/gps_denied_onboard/replay_input/tlog_ground_truth.py reads
  GLOBAL_POSITION_INT (with GPS_RAW_INT fallback) from a binary
  ArduPilot tlog via pymavlink.mavutil and returns a frozen+slotted
  TlogGroundTruth DTO with per-record ts_ns / lat_deg / lon_deg / alt_m
  / hdg_deg / vx_m_s / vy_m_s / vz_m_s.
- Promoted l2_horizontal_m + match_percentage + GroundTruthRow from
  tests/e2e/replay/_helpers.py into the new production module
  src/gps_denied_onboard/helpers/gps_compare.py. The e2e helper now
  re-exports the same objects (identity, not copies) so existing test
  imports continue working untouched.
- tests/e2e/replay/conftest.py prefers the real derkachi.tlog when
  present, falls back to the CSV synth path otherwise.
- 22 new unit tests cover AC-1..AC-5 (mypy --strict subprocess test
  included). All passing.

AZ-702: Topotek KHP20S30 factory-sheet camera calibration

- New _docs/00_problem/input_data/flight_derkachi/khp20s30_factory.json:
  fx = fy = 4644.444, cx = 960, cy = 540, HFOV ~ 23.3 deg, VFOV ~ 13.2
  deg, computed from the published 8.5 mm focal length + 1/2.8" sensor
  + 1920x1080 capture at lowest zoom step. Distortion zeroed,
  body_to_camera_se3 = identity with nadir convention. Acquisition
  method explicitly recorded as factory_sheet so downstream code can
  expect higher residual error than a lab calibration.
- _docs/00_problem/input_data/flight_derkachi/camera_info.md updated
  to document the assumptions, expected residual error window, and
  conftest pick-up rule.
- tests/e2e/replay/conftest.py::_calibration_path() prefers
  khp20s30_factory.json when present, falls back to adti26.json.
- 9 new unit tests cover AC-1..AC-4 (schema, intrinsics traceback,
  doc reference, conftest pick-up). All passing.

Test run: 45 new tests, all passing. Full-suite gate deferred to
Step 16 (after the last batch in cycle 2 per the implement skill).

Adjacent note (not fixed in this batch, recorded in the batch report):
auto_sync.py has the same redundant pymavlink type:ignore + a few
numpy/cv2 mypy --strict issues. None on this batch's path.

Oleksandr Bezdieniezhnykh 9bdc868dfd [AZ-687] Guard build_pre_constructed seeds in replay mode 
Replay CLI synthesizes a minimal Config whose `components` mapping
omits the strategy-component blocks (`c6_tile_cache`, `c7_inference`,
`c5_state`) the airborne bootstrap historically read unconditionally.
Add `_replay_omits_component_block` and gate the c6 seeds, the c7 +
c3_lightglue_runtime pair, and the c5 (estimator, handle) eager build
on `config.mode == "replay" AND block absent`. Live mode and any
replay config that DOES populate the blocks remain unchanged — the
guard is conditional, not blanket.

The skip is safe because compose_root's per-component wrappers only
run for slugs in `config.components`; absent blocks mean absent
wrappers, so the seeded slots would never be read. Fix lives at the
BUILD-PRE-CONSTRUCTED layer per the spec's explicit "no silent fallback
in `_c6_config`" constraint.

Covers AC-687-1 / AC-687-2 / AC-687-4. AC-687-3 (Jetson Tier-2 e2e
replay) requires an out-of-band hardware re-run; evidence destination
documented in autodev state.

Oleksandr Bezdieniezhnykh c3639a5d1c [AZ-624] [AZ-618] Phase F: wire build_pre_constructed into main() 
Wire register_airborne_strategies + build_pre_constructed +
compose_root(config, pre_constructed=...) into runtime_root.main(). The
existing exception block now catches AirborneBootstrapError distinctly
before the broader (ConfigurationError, StrategyNotLinkedError,
RuntimeError) clause so the operator-facing "airborne_bootstrap:"
prefix carried by every bootstrap error reaches stderr cleanly with
EXIT_GENERIC_FAILURE rather than getting absorbed into a generic
backtrace.

This closes the AZ-618 umbrella: AZ-619..AZ-623 + AZ-625 had built
each pre_constructed key; this batch lands the integration that the
production main() actually invokes them. Both the live
gps-denied-onboard and replay gps-denied-replay binaries dispatch
through this main() per ADR-011, so both reach takeoff with
pre_constructed populated end-to-end.

Tests: tests/unit/runtime_root/test_az618_pre_constructed.py adds 6
tests covering AC-618-1..AC-618-4 + AZ-624 local handler-ordering
regression guard. The strategy factories are stubbed at the
airborne_bootstrap module boundary so the test exercises the
integration seam without standing up gtsam / FAISS / TensorRT /
PyTorch / OpenCV at unit-test scope.

AC-618-5 (Jetson tier-2 e2e) is BLOCKED on operator-supplied hardware
evidence: scripts/run-tests-jetson.sh
tests/e2e/replay/test_derkachi_1min.py must run on Jetson Orin Nano
(JetPack 6.2.2+b24) and the terminal log path + JetPack version + run
timestamp captured per _docs/02_document/tests/tier2-jetson-testing.md.

Quality gates: ruff format clean, ruff lint clean, 6/6 new umbrella
tests pass, 261/261 runtime_root + c5_state regression suite passes,
25/25 test_az401_compose_root_replay regression passes, full Tier-1
unit suite 2150/2151 passes (1 unrelated pre-existing failure:
c12_operator_orchestrator subprocess cold-start NFR fails on Mac dev
host's Python startup ~700 ms; not regressed by AZ-624). Code review
verdict PASS (1 Low finding; full report in

Oleksandr Bezdieniezhnykh 2b8ef52f66 [AZ-625] Phase E.5: airborne_bootstrap c5_isam2_graph_handle ordering 
Wire the airborne bootstrap to seed pre_constructed['c5_isam2_graph_handle']
so c4_pose's compose-time lookup is satisfied (c4_pose runs before c5_state in
topological order; the iSAM2 graph handle is built INSIDE the C5 estimator's
constructor and so must be produced eagerly at bootstrap time).

build_pre_constructed now invokes a new internal _build_c5_state_estimator_pair
helper that calls state_factory.build_state_estimator once, captures the
(estimator, handle) tuple, and seeds two slots: 'c5_isam2_graph_handle' for
C4's lookup, and an internal '_c5_prebuilt_estimator' look-aside key for the
C5 wrapper's short-circuit. _c5_state_wrapper checks the look-aside key first
and returns the prebuilt instance as-is — the SAME object the handle was
extracted from, so c4_pose._isam2_handle and c5_state._isam2_handle reference
ONE object across the C4 / C5 seam (AC-625.3 cross-seam identity invariant).

C5_STATE_BUILD_FLAGS mirrors state_factory._STATE_BUILD_FLAGS so the bootstrap
can name the gating BUILD_STATE_* flag in operator errors before the lower
level StateEstimatorConfigError fires (AC-625.2). When the factory itself
rejects the configuration with the flag ON, the error wraps into
AirborneBootstrapError with __cause__ preserved (matches AZ-621 / AZ-622
patterns).

Constraints respected per AZ-618 umbrella: no per-component factory signature
changed; additive on top of AZ-619..AZ-623; no edits under state_factory,
pose_factory, or c5_state internals.

Tests: tests/unit/runtime_root/test_az625_c5_isam2_graph_handle_ordering.py
adds 8 tests covering AC-625.1..3 (presence + Protocol conformance, internal
key invariant, BUILD-flag-OFF error, unknown-strategy error, factory error
wrapping, cross-seam identity, wrapper short-circuit, wrapper fallback).
Autouse stubs added to test_az619/620/621/622/623 so prior phase tests stay
isolated from the new builder.

Quality gates: ruff format clean, ruff lint clean, 32/32 phase tests pass,
255/255 runtime_root + c5_state regression suite passes. Code review verdict
PASS (2 Low findings; full report in
_docs/03_implementation/reviews/batch_95_review.md).

Oleksandr Bezdieniezhnykh 02208c577e [AZ-623] [AZ-625] Phase E: c282_ransac + c5 helpers; split handle work 
Wire 4 stateless / cached helpers into airborne_bootstrap.build_pre_constructed:
c282_ransac_filter, c5_imu_preintegrator (cached on calibration path),
c5_se3_utils (helpers.se3_utils module as namespace handle), c5_wgs_converter.

The original AZ-623 5th deliverable (c5_isam2_graph_handle) hit an
unresolvable construction-order conflict between c4_pose (consumes the handle)
and c5_state (creates it inside build_state_estimator's tuple return) under
the umbrella's "MUST NOT touch any per-component factory signature" constraint.
Per AZ-623 spec's escalation gate, scope was split: AZ-625 captures the handle
ordering work; AZ-624 dependency edge updated to require both.

Tests: tests/unit/runtime_root/test_az623_pre_constructed_phase_e.py adds 7
tests covering AC-623.1..3 (4 new keys + correct types, IMU preintegrator
caching, operator-actionable error messages for empty / unreadable / malformed
calibration paths). Autouse stubs added to test_az619/620/621/622 so prior
phase tests remain isolated from new builders.

Quality gates: ruff format clean, ruff lint clean, 24/24 phase tests pass,
247/247 runtime_root + c5_state regression suite passes. Code review verdict
PASS_WITH_WARNINGS (3 Low findings; full report in
_docs/03_implementation/reviews/batch_94_review.md).

of AZ-619/620/621. Strategy-specific BUILD_MATCHER_* flag mismatch
raises AirborneBootstrapError naming the missing flag and the c3_matcher
consumer; the c7 InferenceRuntime built earlier in the bootstrap is
reused as the engine source so no double-build at this layer.

C3MatcherConfig gains optional lightglue_weights_path: Path | None
for the operator's deployment config; production main() (AZ-624)
populates it. Real LightGlue inference correctness is verified by
AZ-624's Jetson AC-5 run per the AZ-622 Tier-2 Note.

Phase tests for AZ-619/620/621 gain an autouse _stub_c3_matcher_builders
fixture so additivity assertions remain valid as the bootstrap grows.

Code review: PASS_WITH_WARNINGS (3 Low: signature drift from spec,
_is_build_flag_on duplication across 3 runtime_root modules, and
BuildConfig literal mirrored with per-strategy build configs). All
deferred to future hygiene PBIs.

Oleksandr Bezdieniezhnykh 680ba29ae6 [AZ-621] Phase C: build_pre_constructed seeds c7_inference 
Third subtask of AZ-618. Extends airborne_bootstrap.build_pre_constructed
additively with c7_inference (GPU InferenceRuntime). Wraps the existing
inference_factory.build_inference_runtime so a BUILD_TENSORRT_RUNTIME /
BUILD_PYTORCH_FP16_RUNTIME mismatch surfaces a clear operator-facing
AirborneBootstrapError naming BOTH airborne C7 flags plus the consuming
component slug, rather than bubbling up RuntimeNotAvailableError with no
context.

New public const C7_AIRBORNE_BUILD_FLAGS pairs each airborne runtime
with its gating env flag (onnx_trt_ep deliberately omitted — research
only). Tests stub at the factory boundary; real GPU/TensorRT load
remains Tier-2 only (consolidated at AZ-624). AZ-619 and AZ-620 test
files extended with a _stub_c7_inference_builder autouse fixture
mirroring the AZ-620 pattern for _build_c6_*.

18/18 runtime_root unit tests pass.

Oleksandr Bezdieniezhnykh 7dc38fdd3e [AZ-620] Phase B: build_pre_constructed seeds c6_descriptor_index + c6_tile_store 
Second of six subtasks of AZ-618. Extends
airborne_bootstrap.build_pre_constructed(config) additively with the
two C6 storage entries on top of AZ-619's c13_fdr + clock contract:

- c6_descriptor_index: via storage_factory.build_descriptor_index
- c6_tile_store:       via storage_factory.build_tile_store

When BUILD_FAISS_INDEX=OFF, the lower-level RuntimeNotAvailableError
from the descriptor index factory is translated into an
AirborneBootstrapError that names the missing key
(c6_descriptor_index), the gating flag (BUILD_FAISS_INDEX), and the
consuming component slug(s) drawn from
AIRBORNE_REQUIRED_PRE_CONSTRUCTED_KEYS. The original error is
preserved as __cause__ so operators still see the upstream reason.

Tests: 3 new unit tests cover AC-620.1 + AC-620.2 (twice, with and
without a configured consumer, so the bootstrap fails loudly in
either branch). AZ-619 tests updated to add an autouse stub for the
Phase B builders (keeps them focused on Phase A keys) and to relax
the "exactly two keys" assertion to "AZ-619 keys remain present
under AZ-620 additivity" per the original test's own forward-pointer.

Bonus: ruff --fix removed 12 pre-existing UP037 quoted-annotation
warnings in airborne_bootstrap.py (covered by `from __future__ import
annotations`). All in modified-area scope per quality-gates.mdc.

Run: pytest tests/unit/runtime_root/ -q -> 15/15 passed in 1.06s.

Spec moved to _docs/02_tasks/done/ in the previous commit (audit-trail
backfill of batch_90 also landed there).

Oleksandr Bezdieniezhnykh 8abfb020fe [AZ-619] Phase A: build_pre_constructed seeds c13_fdr + clock 
Adds airborne_bootstrap.build_pre_constructed(config) returning a
dict with the two foundational keys: a per-binary shared FdrClient
under "c13_fdr" (via make_fdr_client with the new
AIRBORNE_MAIN_PRODUCER_ID constant) and a fresh WallClock under
"clock". Phases B..F (AZ-620..AZ-624) extend this function
additively without breaking the AZ-619 contract.

The c13_fdr instance is identity-stable across calls (per the
make_fdr_client per-producer cache) so callers can call
build_pre_constructed twice and get the same FdrClient back -
AC-619.2.

Replay-mode override is unchanged: compose_root merges
replay_components over pre_constructed so the WallClock here is
replaced by TlogDerivedClock in replay binaries (existing
contract documented in compose_root's docstring).

Tests: 5 new unit tests under tests/unit/runtime_root/
test_az619_pre_constructed_phase_a.py, all passing. AZ-591 not
regressed (12/12 in the combined run).

Spec moved to _docs/02_tasks/done/.

Oleksandr Bezdieniezhnykh bd41956164 [AZ-611] Add --skip-auto-sync flag to bypass AC-9 validator 
Mid-flight fixtures (Derkachi) and stationary-still scenarios
(FT-P-01) have no take-off spike for the IMU detector and produce
false-positive video motion onsets, so the AC-9 frame-window
validator rejects every plausible offset. Add an operator-acknowledged
opt-out: a new ReplayConfig.skip_auto_sync_validation flag that
suppresses validation, paired with a hard requirement that
time_offset_ms also be set (silent-zero guard at both schema and
adapter layers).

Wired through schema -> CLI (--skip-auto-sync) -> composition root
-> ReplayInputAdapter; Derkachi e2e fixture now passes
time_offset_ms=0 + skip_auto_sync=True by default since the synth
tlog and the video share the same t=0 anchor by construction.

5 new unit tests:
  * schema gate rejects skip=True without manual offset
  * schema gate accepts the legal pair
  * default field value is False (default-construction safety)
  * adapter constructor mirrors the schema gate
  * adapter open() bypasses validate_offset_or_fail when flag is set

All 38 unit tests in test_az401 + test_az405 pass on Mac.

Oleksandr Bezdieniezhnykh e114bfd9b8 [AZ-614] tlog synth: anchor at t=0 to align with video time-base 
The Derkachi auto-sync coordinator compares absolute tlog timestamps
(from pymavlink's 8-byte record header) against absolute video
timestamps (CAP_PROP_POS_MSEC, which starts at 0). Anchoring the
synthetic tlog at 1_700_000_000_000_000 us (2023-11-14) produced a
~53-year offset (offset_ms=1699999995666) that always tripped the
AC-9 frame-window match validator at 0% match.

Setting the base to 0 puts the tlog on the same axis as the video
(and matches the CSV's `Time` column, which is seconds since row 0
per `_docs/00_problem/input_data/flight_derkachi/README.md`: "the
video and telemetry align at exactly three video frames per
telemetry row").

Verified on Colima with GPS_DENIED_TIER=2: the offset reported by
the auto-sync coordinator drops from 1699999995666 ms to -4334 ms.
The remaining 4.3 s offset is NOT a synth issue — it's the tlog
take-off detector (no signal in the steady-cruise CSV → defaults to
samples.accel[0][0] == 0) vs the video motion-onset detector (which
fires on a scenery-contrast false positive at ~4.3 s). The synth
cannot fabricate a take-off spike at the right time without knowing
the video motion-onset moment a priori, and the README confirms the
fixture is mid-flight footage with no take-off in either signal.

Resolving the remaining 4.3 s mismatch requires SUT-side work to
honor the documented "manual offset bypasses auto-sync" contract —
that's the scope of AZ-611. Filed as a known limitation in the
commit message; AC-1..AC-6 still red until AZ-611 lands.

Oleksandr Bezdieniezhnykh 58a1678417 [AZ-615] Dockerfile.jetson: fix pip indices + prerelease resolver 
Three discoveries from on-Jetson build (image builds clean in ~3m18s
after fixes; gtsam-4.3a0, torch 2.4.0+cuda, cv2 4.11.0 all import OK
inside container running --runtime=nvidia):

1. dustynv/l4t-pytorch's /etc/pip.conf bakes in a local Jetson mirror
   (jetson.webredirect.org) that's only reachable from the maintainer
   LAN. pip's DNS lookup fails everywhere else. Wipe the config and
   pin --index-url to upstream PyPI.
2. The image ships pip 24.2. The SUT's `gtsam<5.0,>=4.2` constraint
   matches ONLY gtsam-4.3a0 on PyPI (no stable aarch64 wheels), and
   pip 24.x rejects pre-releases unless --pre is set. The Colima
   image lands on the same wheel because its pip 26.x has explicit
   fallback-to-pre-release logic. Bump pip before installing the SUT
   to align resolver behavior across both harnesses.
3. Skip the [inference] extra entirely — the base image ships
   Tegra-tuned torch / torchvision that re-pip would clobber with
   x86 builds lacking cuDNN/cuBLAS for Orin.

Oleksandr Bezdieniezhnykh 6586208f83 [AZ-615] Fix Jetson harness base image (l4t-base/l4t-pytorch tags don't exist) 
Operator-reported: `nvcr.io/nvidia/l4t-base:r36.4.0` fails to pull.
Investigation against the live registries confirmed:

  * `nvcr.io/nvidia/l4t-base` — deprecated in JetPack 6, no r36 tags
    (forum thread "L4T Base docker image for Jetpack 6.2 (r36.4.3)",
    GitHub dusty-nv/jetson-containers#883).
  * `nvcr.io/nvidia/l4t-pytorch` — no r36 tags at all. Newest is
    r35.2.1-pth2.0-py3 (too old for our torch>=2.2 floor).
  * `nvcr.io/nvidia/l4t-jetpack:r36.4.0` — exists but ships no PyTorch.
  * `dustynv/l4t-pytorch:r36.4.0` (Docker Hub) — exists, ~6.3 GB ARM64,
    PyTorch + torchvision + opencv pre-baked, maintained by dusty-nv
    (NVIDIA's Jetson containers maintainer).

Switched Dockerfile.jetson base to `dustynv/l4t-pytorch:r36.4.0`.
Forward-compatible with the host's R36.5 BSP (NVIDIA containers
tolerate one minor BSP ahead on the host side).

Setup doc fixes:
  * smoke-test command now uses `l4t-jetpack:r36.4.0` (the official
    replacement for the deprecated `l4t-base`)
  * keygen step explicitly states it produces BOTH halves (private +
    .pub) in one go
  * ssh-copy-id + ssh config show how to specify a custom port
  * troubleshooting table gets a new row for the `l4t-base not found`
    case so the next dev hits the answer in 30 seconds

Oleksandr Bezdieniezhnykh 9c13ab3bd0 [AZ-615] [AZ-617] Add Jetson e2e harness + tier2 marks 
C7 inference (PytorchFp16Runtime / TensorRTRuntime / OnnxTrtEpRuntime)
is CUDA-only by design — `model.half().cuda()` is hard-wired with no
CPU fallback. The Colima/Tier-1 smoke harness can never exercise C3
matcher or C7 inference. Once AZ-614 fixes the tlog time-base mismatch
and the pipeline reaches those stages, Colima runs would hard-fail at
`.cuda()` instead of cleanly skipping.

This commit lays down the Jetson companion harness and wires the
existing `tier2` auto-skip:

  * tests/e2e/Dockerfile.jetson  — l4t-pytorch:r36.4.0-pth2.3-py3 base,
    same /opt layout as the Colima image so AC-4 AST scan + bind mounts
    work identically. Built ON the Jetson via run-tests-jetson.sh.
  * docker-compose.test.jetson.yml — mirrors docker-compose.test.yml
    but with `runtime: nvidia`, GPU device exposure, and
    GPS_DENIED_TIER=2 (turns OFF the tier2 auto-skip).
  * scripts/run-tests-jetson.sh — rsync → ssh build → ssh up,
    exit-code-from e2e-runner so the local exit code reflects the
    remote test verdict. No credentials in the repo; uses
    `ssh jetson-e2e` alias resolved via ~/.ssh/config.
  * _docs/03_implementation/jetson_harness_setup.md — one-time SSH
    key + alias + sshd hardening + GPU verification steps. Documents
    the smoke vs. Reality Gate split + the GPS_DENIED_TIER switch.

AZ-617 (mark heavy ACs with tier2): adds @pytest.mark.tier2 to AC-1,
AC-2, AC-3, AC-5, AC-6 in tests/e2e/replay/test_derkachi_1min.py.
Reuses the existing tier2 marker + auto-skip in tests/conftest.py
(scope revision documented as a comment on AZ-617). AC-4a/4b/AC-7/AC-9
stay unmarked — they don't touch CUDA.

Defers to follow-up Jira:

  * AZ-614 — Derkachi tlog synth time-base mismatch (unblocks tier2 ACs
    actually reaching the GPU stage on the Jetson)
  * AZ-616 — replace mock-sat with real ../satellite-provider service

Not run yet: the harness needs operator-side SSH setup to come online
before scripts/run-tests-jetson.sh can be executed end-to-end. Setup
steps documented in jetson_harness_setup.md.

Oleksandr Bezdieniezhnykh c2934b8686 [AZ-603] [AZ-604] e2e-runner: install SUT, fix entrypoint (Track 1) 
Multi-stage Ubuntu 22.04 e2e-runner image installs gps-denied-onboard
(editable) into /opt/venv so the AZ-404 replay tests can subprocess
gps-denied-replay against the Derkachi fixture. Image layout mirrors
the host repo (/opt/pyproject.toml + /opt/src + /opt/tests bind mount)
so Path(__file__).parents[3] resolves to /opt and AC-4's AST scan
finds the components dir.

Entrypoint now runs `pytest /opt/tests/e2e/` instead of the empty
`scenarios/` dir. The bootstrap harness collects 24 tests vs. 0 before.

Compose: e2e-runner env mirrors the companion service (FullSystemConfig
requirements) plus RUN_REPLAY_E2E=1, BUILD_REPLAY_SINK_JSONL=ON;
bind-mounts the Derkachi fixture dir; adds writable fdr-data /
tile-data volumes the SUT requires.

Reality Gate signal is now real: 17 pass / 5 fail / 1 skip / 1 xfail.
The 5 heavy-AC failures share root cause AZ-614 (tlog synth time-base
mismatch, surfaced by the now-functional harness).

Also archives the replayed leftover entries (csv_reporter -> AZ-601,
harness rehab -> AZ-602 epic + 11 child stories).

Oleksandr Bezdieniezhnykh 5c1c35da9a [autodev] step-11 path-3: calibration fix + harness drift report 
Attempted Path-3 (Full SITL with community images) for the SUT Reality
Gate. Discovered sitl_observer is offline-fixture replay, not a live
SITL client -- compose-file SITL services in environment.md are
aspirational. The real Path-3 needs the fixture builders + SUT CLI
end-to-end, which surfaced 5 additional integration drifts (H-10..H-14)
on top of the prior 9.

Fixes:
- tests/fixtures/calibration/adti26.json: body_to_camera_se3 was a
  {rotation_xyzw, translation_xyz_m} dict; runtime_root/_replay_branch.py
  loader strictly expects a 4x4 SE3. Identity quaternion + zero
  translation = identity 4x4, semantically equivalent.

New files:
- tests/fixtures/replay_config_minimal.yaml: minimal replay-mode config
  for harness reproduction (mode=replay, ardupilot_plane defaults).
- .gitignore: e2e/fixtures/sitl_replay/ (generated by build_p0X_fixtures).

Documentation:
- Step 11 report: appended Path-3 attempt section.
- Leftover doc: H-10..H-14 ticket payloads added.
- Autodev state: reflects Path-3 outcome.

Step 11 stays blocked; H-13 (auto-sync AC-8 hard-fails on stationary
fixtures) requires a SUT design decision and cannot be unilaterally
fixed mid-session.

Oleksandr Bezdieniezhnykh f7a99282fb [AZ-591] Add airborne_bootstrap to populate _STRATEGY_REGISTRY 
Batch 66 — fixes the production gap surfaced during the cycle-1
completeness-gate post-mortem: the central _STRATEGY_REGISTRY was
empty in production source, so compose_root() raised
StrategyNotLinkedError on the first component lookup and the
airborne binary couldn't reach takeoff.

Changes:

- New module `src/.../runtime_root/airborne_bootstrap.py` exposes
  `register_airborne_strategies()` and a documented
  `AIRBORNE_REQUIRED_PRE_CONSTRUCTED_KEYS` table. The function
  registers 14 entries into the central registry across 7
  strategy-selecting slots (c1_vio + c2_vpr + c2_5_rerank +
  c3_matcher + c3_5_adhop + c4_pose + c5_state). Per-slot wrappers
  adapt the registry-factory signature (config, constructed) to each
  per-component factory's kwarg surface and surface a
  AirborneBootstrapError when a required infrastructure dep is
  missing from constructed.

- `compose_root` gains a `pre_constructed` kwarg in live mode,
  symmetric with the replay-mode seam. Replay entries still take
  precedence on key collision (ADR-011). Existing callers unaffected
  (kwarg defaults to None).

- `runtime_root/__init__.py::main()` now calls
  `register_airborne_strategies()` before `compose_root(config)` so
  production binaries no longer crash at the registry-lookup step.

- Lazy-loading preserved: state_factory's private _STATE_REGISTRY is
  populated lazily inside the c5_state wrapper, gated by
  BUILD_STATE_GTSAM_ISAM2 / BUILD_STATE_ESKF env flags. pose_factory's
  own lazy-import fallback handles c4_pose without an explicit
  register() call.

- 7 new unit tests in `tests/unit/runtime_root/test_az591_airborne_\
  bootstrap.py` cover AC-1..AC-5 plus the negative-path
  AirborneBootstrapError contract. Full unit suite 2105 passed / 88
  environment-gated skips / 0 failures.

End-to-end takeoff still needs a follow-up task to wire infrastructure
pre-construction (c13_fdr / c6_* / c7_inference / etc.) into the
pre_constructed dict passed to compose_root. That follow-up is gated
by AZ-591 landing first; recommended split into per-component
infrastructure-prep tasks (3pt each).

Oleksandr Bezdieniezhnykh c5ffc14fe9 [AZ-389] C5 orthorectifier emits mid-flight tiles to C6 
Adds an opt-in C5-internal orthorectifier (`_orthorectifier.py`) that
emits at most one tile-aligned JPEG candidate per nav frame to the
C6 `TileStore.write_tile` API.  Quality gates fire before any
OpenCV work: covariance Frobenius, inlier floor, source-label
(`SATELLITE_ANCHORED` only), and once-per-frame rate limit.

Cross-component import rule (AZ-507) is preserved: c5_state never
imports c6_tile_cache.  `runtime_root.state_factory` carries a new
`_C6MidFlightIngestAdapter` that builds the canonical
`TileMetadata` (`ONBOARD_INGEST` / `FRESH` / `PENDING`), hashes
the JPEG, and translates `FreshnessRejectionError` to a `None`
return so the orthorectifier silently swallows freshness
rejection per AC-NEW-3.

Wiring is opt-in via `C5StateConfig.orthorectifier.enabled`;
existing tests/binaries default to disabled and are unaffected.
Both `GtsamIsam2StateEstimator` and `EskfStateEstimator`
participate through new `attach_orthorectifier` /
`set_latest_nav_frame` extension methods (Protocol surface
unchanged).

Tests: 22 new unit tests cover AC-1..AC-9 plus inlier-floor
gate plus the composition-root adapter.  216/216 c5_state and
38/38 runtime-root + compose tests pass.

Oleksandr Bezdieniezhnykh 2b19b8b90b [AZ-558] Route C8 outbound encoder bytes through MavlinkTransport seam 
All FC adapter outbound MAVLink bytes now go through the AZ-401
MavlinkTransport seam (NoopMavlinkTransport in replay,
SerialMavlinkTransport in live). New helpers in
_outbound_mavlink_payloads.py extract encode/pack/seq-bump so the four
AP _send sites and the iNav statustext _send site become
encode -> pack -> transport.write. TlogReplayFcAdapter emits real
AP-shape MAVLink bytes through the injected NoopMavlinkTransport,
satisfying replay protocol Invariant 5 and unblocking AZ-401 AC-9.

Closes AZ-558. Also unskips AZ-401 AC-9 and AZ-404 AC-4b. Live wire
output remains byte-identical (proven via two-instance MAVLink
byte-equivalence tests). AST scan asserts no .mav.<name>_send( calls
remain in the retrofit set (AP / iNav / tlog adapters).

Out of scope (logged in review): GCS adapter retrofit; airborne live
strategy registration that would activate the SerialMavlinkTransport
factory injection path.

Tests: 2110 passed, 92 environmental skips, 1 unrelated pre-existing
macOS cold-start flake deselected.

Oleksandr Bezdieniezhnykh d7e6b0959e [AZ-404] [AZ-389] [AZ-559] E2E replay test (Derkachi 60s) + AZ-389 cleanup 
Batch 63 of /autodev replay slice. Adds the AZ-404 E2E test harness
against the Derkachi fixture and resolves the AZ-389 dependency
phantom (closing AZ-559 Won't Fix).

E2E test (AZ-404)
- tests/e2e/replay/_tlog_synth.py: deterministic CSV->tlog generator
  (the original Derkachi tlog is not in repo; data_imu.csv is its
  export, so we round-trip the CSV through pymavlink). Verified:
  SCALED_IMU2 + ATTITUDE + GPS_RAW_INT + HEARTBEAT round-trip cleanly
  through mavutil.mavlink_connection.
- tests/e2e/replay/_helpers.py: parse_jsonl, l2_horizontal_m
  (haversine), match_percentage, CapturingMavlinkTransport (ready
  for AZ-558 unblock), GroundTruthRow + load_ground_truth_csv.
- tests/e2e/replay/conftest.py: derkachi_replay_inputs (session
  scope), replay_runner (subprocess fixture per AZ-402 CLI),
  operator_pre_flight_setup placeholder.
- tests/e2e/replay/test_derkachi_1min.py: 9 tests covering AC-1..AC-8
  with AC-7 skip-gate self-check + AC-4a mode-agnosticism AST scan
  (passes unconditionally, confirms ADR-011 holding).
- tests/e2e/replay/test_helpers.py: 14 unit tests covering AC-9
  helper L2 correctness + match_percentage + parse_jsonl +
  CapturingMavlinkTransport (all unconditional).
- tests/e2e/replay/README.md: AC matrix, fixture state, runtime
  budget, failure cookbook (AC-10).

AC matrix
- AC-1, AC-2, AC-5, AC-6 implemented and Tier-1 gated on
  RUN_REPLAY_E2E=1.
- AC-3 (<=100m for 80%) xfail until real Topotek KHP20S30
  calibration ships (camera_info.md states intrinsics are unknown).
- AC-4a (mode-agnosticism AST scan) PASSES unconditionally.
- AC-4b (encoder byte-equality) skip until AZ-558 routes C8 bytes
  through MavlinkTransport.
- AC-7 (skip-gate self-check) PASSES unconditionally.
- AC-8 (operator workflow rehearsal) skip until D-PROJ-2
  mock-suite-sat-service implements tile-fetch + index-build
  endpoints.
- AC-9 (helper L2 correctness) 14 PASSES unconditionally.

AZ-389 housekeeping
- AZ-559 closed Won't Fix: investigation against
  c6_tile_cache/_types.py confirmed TileSource.ONBOARD_INGEST +
  TileMetadata.quality_metadata + write_tile's FreshnessRejectionError
  already cover the mid-flight ingest semantic. The "missing API"
  was a spec-vs-impl naming mismatch.
- AZ-389 spec rewritten to consume the existing write_tile API +
  catch FreshnessRejectionError per AC-NEW-3 opportunistic emission.
- _dependencies_table.md reverted: AZ-389 deps -> AZ-303 (was
  AZ-559 in the previous commit on this branch); total 150 / 497
  pts.

Tests
- Full regression: 2099 passed (+14 new e2e/replay), 94 skipped
  (incl. 8 e2e/replay heavy-tier + documented blocker skips), 3
  perf-microbench flakes deselected (test_cli_cold_start_under_2s,
  test_cold_start_under_500ms_p99, test_nfr_perf_sign_microbench;
  all pass in isolation - pre-existing under-load flakes on dev
  macOS).

Reviews
- _docs/03_implementation/reviews/batch_63_review.md: code review
  PASS_WITH_WARNINGS (3 documented spec-gap deferrals: AC-3, AC-4b,
  AC-8).
- _docs/03_implementation/cumulative_review_batches_61-63_cycle1_report.md:
  cumulative review PASS_WITH_WARNINGS. Action items: prioritise
  AZ-558 (closes AZ-401 AC-9 + AZ-404 AC-4b); consider 2pt hygiene
  PBI for Protocol-completeness AST scan to catch the AZ-389 /
  AZ-559 phantom-API pattern at task-prep time.

Architecture invariants observably holding
- ADR-011 (replay-as-configuration): AC-4a's AST scan over
  src/gps_denied_onboard/components/**/*.py finds zero violations -
  components branch on neither config.mode nor any synonym.
- Single composition root (replay protocol Invariant 11): AZ-402

Oleksandr Bezdieniezhnykh 2c31cc094f [AZ-402] Replay — gps-denied-replay console-script + shared main(config) 
Implements the replay-mode CLI dispatcher per ADR-011 (replay-as-
configuration):

- src/gps_denied_onboard/cli/replay.py: argparse with all 6 required
  args (--video, --tlog, --output, --camera-calibration, --config,
  --mavlink-signing-key) plus --pace and --time-offset-ms; path
  validation, calibration JSON schema-validation, config mutation
  (mode='replay' + replay sub-block + signing-key hex on dev_static
  field), dispatch into runtime_root.main(config).
- runtime_root.main() now accepts an optional Config (additive,
  backward-compat). Adds dedicated catch for ReplayInputAdapterError
  mapping to EXIT_FDR_OPEN_FAILURE (2) so the CLI's exit-code matrix
  holds end-to-end (AC-9 + epic AZ-265 AC-8).
- Signing-key contents stored as hex; redacted in startup banner.
- Top-level except logs full traceback via logger.exception + stderr
  print and exits 1.

The CLI does NOT call compose_root directly — it builds a Config and
hands it to the shared airborne main, which calls compose_root, which
branches on config.mode (AZ-401 / replay protocol Invariant 11).

Tests: 22 unit tests covering AC-1..AC-10 + extras (signing-key
redaction, file-not-dir validation, dev_static propagation, unhandled
exception traceback). Full regression: 2085 passed (+22) green; no
new flaky tests.

Oleksandr Bezdieniezhnykh 17a0d074af [AZ-401] [AZ-400] Replay — compose_root replay-mode branch + transport seam 
Wires the airborne composition root for replay-as-configuration (ADR-011):

- compose_root(config) branches on config.mode in {"live", "replay"}.
  Live behaviour is unchanged; replay builds ReplayInputAdapter,
  attaches JsonlReplaySink, and injects NoopMavlinkTransport.
- New private module runtime_root/_replay_branch.py holds the
  replay-only strategy graph + build-flag gate + calibration loader.
- Config gains Config.mode (Literal["live","replay"]) plus
  Config.replay sub-block with nested ReplayAutoSyncConfig that mirrors
  the AZ-405 AutoSyncConfig DTO; YAML loader + ENV map updated.

Absorbs the AZ-400 transport-seam retrofit that AZ-401 strictly
required but AZ-400 had not delivered:

- New MavlinkTransport Protocol (write/bytes_written/close).
- NoopMavlinkTransport (replay; build-flag gated, idempotent close,
  thread-safe byte counter).
- SerialMavlinkTransport (live, no-op restructure of existing pymavlink
  byte path; encoder retrofit to actually USE it is the AZ-558
  follow-up).

AZ-401 AC-9 (NoopMavlinkTransport.bytes_written > 0 after C8 encoders
run) is BLOCKED on AZ-558 — the encoder routing retrofit is out of
the AZ-401 task envelope (FORBIDDEN files: pymavlink_ardupilot_adapter,
msp2_inav_adapter). AZ-558 spec, batch_61_review.md, and the test's
@pytest.mark.skip rationale all carry the deferral reason.

Tests: 22 compose_root replay-branch tests + 17 transport tests.
Full regression: 2063 passed, 86 environment-skips, 1 documented
skip (AC-9 / AZ-558), 1 pre-existing flaky perf test deselected.

Oleksandr Bezdieniezhnykh 8149083cac [AZ-405] Replay — replay_input/ coordinator + IMU take-off auto-sync 
Adds the Layer-4 cross-cutting `replay_input/` module per ADR-011:
ReplayInputAdapter converges (video, tlog) into the standard
FrameSource + FcAdapter + Clock surfaces the airborne composition
root consumes. Owns time-alignment between video frames and tlog
IMU/attitude ticks (manual via --time-offset-ms or auto via the
AZ-405 IMU-take-off detector + Farneback motion-onset detector).

Auto-sync algorithm (auto_sync.py):
- Tlog take-off detector: sustained vertical-accel excess > 0.5 g for
  >= 0.5 s + sustained attitude-rate magnitude > 1 rad/s.
- Video motion-onset detector: dense Farneback flow magnitude > 1.5 px
  sustained >= 0.5 s (deterministic per AC-10).
- compute_offset combines the two; confidence = min(tlog, video).
- validate_offset_or_fail implements the AC-9 95 % frame-window match
  validator with configurable threshold + window.

ReplayInputAdapter.open() ordering (AC-13):
1. Load tlog samples + fail-fast on missing RAW_IMU/SCALED_IMU2 or
   ATTITUDE BEFORE any video read.
2. Resolve offset (auto-sync OR manual override; manual bypasses the
   detectors entirely per AC-8).
3. Run AC-9 validator on resolved offset; raise auto-sync hard-fail
   for AC-7 (CLI exit 2 mapping).
4. Build single Clock instance per pace (TlogDerived/ASAP, Wall/REAL).
5. Construct VideoFileFrameSource and TlogReplayFcAdapter with the
   resolved offset baked in (replay protocol Invariant 8).

Structured log + FDR records on auto-sync detected / low-confidence /
AC-8 hard-fail kinds. Idempotent close (AC-12).

Tests: 25 unit tests across tests/unit/replay_input/ covering all 13
ACs (kernel-level synthetic fixtures for AC-1..AC-10; coordinator-
level OpenCV synthetic videos + faked pymavlink for AC-6..AC-13).

Contract update: replay_protocol.md v2.0.0 added fdr_client to the
ReplayInputAdapter __init__ signature (was missing in the prose; the
task spec already listed it in the allowed-imports section).

Oleksandr Bezdieniezhnykh fa3742d582 [AZ-399] [AZ-400] C8 TlogReplayFcAdapter + ReplaySink + JsonlReplaySink 
Opens E-DEMO-REPLAY (AZ-265): the two C8 strategies that let the
upcoming compose_replay (AZ-401) and gps-denied-replay CLI (AZ-402)
run the production C1-C5 pipeline against a recorded (.tlog, video)
pair without touching live FC I/O.

AZ-400 lands the contract ReplaySink Protocol (emit + close per
replay_protocol.md v1.0.0) and JsonlReplaySink: orjson-serialised
JSONL, fsync-on-close, build-flag gated (BUILD_REPLAY_SINK_JSONL),
double-close idempotent, FDR mirror on open/close. The drifted
AZ-390 stub in interface.py is removed; the canonical Protocol now
lives in replay_sink.py per module-layout.md and is re-exported via
__init__.py. AZ-390 conformance test widened.

AZ-399 lands TlogReplayFcAdapter: full FcAdapter Protocol surface,
build-flag gated (BUILD_TLOG_REPLAY_ADAPTER), pymavlink stream-parse
with bounded pre-scan + fail-fast on missing required messages
(R-DEMO-3), dedicated decode thread feeding the existing AZ-391
SubscriptionBus. Outbound surface raises FcEmitError per Invariant 5;
request_source_set_switch raises SourceSetSwitchNotSupportedError.
Pacing honours Invariant 6 via Clock.sleep_until_ns. time_offset_ms
shifts every emitted received_at per Invariant 8. Non-monotonic
timestamps raise FcOpenError.

Test coverage: 188 c8_fc_adapter tests pass; 1 skipped (AZ-399 AC-1
500 MB tlog RSS bound, deferred to AZ-404 e2e behind RUN_REPLAY_E2E).
Code review: PASS_WITH_WARNINGS — 1 Medium (mapping logic duplicates
AZ-391 live decoder; intentional today, four behavioural deltas
documented), 2 Low.

Oleksandr Bezdieniezhnykh 4eac24f37a [AZ-358] [AZ-361] C4 OpenCVGtsamPoseEstimator + Jacobian thermal hybrid 
Implement the single production-default C4 PoseEstimator strategy.

AZ-358 — Marginals path: OpenCV solvePnPRansac (SOLVEPNP_IPPE) on
best-candidate inliers, PriorFactorPose3 with Jacobian-derived initial
covariance, flushed into C5's iSAM2 graph via the widened
ISam2GraphHandle.update(graph, values, None) (Option B). Posterior
covariance from compute_marginals().marginalCovariance(pose_key) with
SPD-defensive Cholesky check. Tile pixel -> ENU world conversion via
the shared WgsConverter + a configurable tile_size_px. Two spec
deviations now documented in the AZ-358 task file: PriorFactorPose3
over GenericProjectionFactorCal3DS2 (avoids unbounded landmark
variables; same Fisher information on the pose marginal) and explicit
(graph, values, timestamps) update args (aligns with C5's impl).

AZ-361 — Jacobian + thermal hybrid: per-frame dispatch on
thermal_state.thermal_throttle_active selects the cv2.projectPoints-
derived 6x6 information matrix (with ridge regularisation) as the
emitted covariance. Skips the iSAM2 factor add under throttle
(Invariant 12). Emits CovarianceDegradedWarning via warnings.warn
(never raised); paired WARN log + FDR record rate-limited per
covariance_degraded_warn_window_ns (default 60 s) via an injected
monotonic Clock. Supersedes the AZ-358 NotImplementedError stub.

Widens ISam2GraphHandle from get_pose_key only to all five C4-facing
methods (add_factor, update, compute_marginals, last_anchor_age_ms);
C5's existing ISam2GraphHandleImpl already satisfies the superset, so
no C5 source change this batch. Threads fdr_client + clock through
pose_factory composition.

Registers two new FDR payload kinds: pose.frame_done (per-call
telemetry; both success and PnpFailureError paths) and
pose.covariance_degraded (per-window throttle exposure).

Tests: 21 new (AZ-358 AC-1..11 + AZ-361 AC-1..10/12/13; AZ-361 AC-11
RMSE-ratio informational per spec, not asserted). Updates 2 existing
test files for Protocol widening and the FDR-schema round trip.

Code review verdict: PASS_WITH_WARNINGS (5 findings: Medium x2,
Low x3; none blocking). Full suite: 1958 passed, 1 unrelated
host-dependent perf failure (c12 CLI cold-start, pre-existing).

Oleksandr Bezdieniezhnykh a1185d0a28 [AZ-345] [AZ-346] [AZ-347] [AZ-349] C3 matchers + C3.5 AdHoP refiner 
Implement the three concrete C3 CrossDomainMatcher strategies plus the
C3.5 production-default AdHoPRefiner.

C3 (AZ-345/346/347):
- DiskLightGlueMatcher + AlikedLightGlueMatcher share a single shared
  _pipeline.run_lightglue_pipeline orchestrator (decode -> query
  extract -> per-candidate loop -> RANSAC sort -> health update ->
  FDR emit) so the only per-backbone delta is the keypoint+descriptor
  extractor closure. ALIKED adds a create-time engine output-schema
  probe (AC-special-1).
- XFeatMatcher owns its own per-candidate loop (single forward fuses
  extraction + matching); it re-uses the shared FDR emission helpers
  to keep telemetry byte-identical across strategies. lightglue_runtime
  parameter accepted by factory but discarded (AC-special-1).
- All three consume the shared LightGlueRuntime / RansacFilter /
  RollingHealthWindow helpers; no helper forks. InferenceRuntimeCut
  consumer-side Protocol added per AZ-507.

C3.5 (AZ-349):
- AdHoPRefiner implements the <= conditional gate, runs the OrthoLoC
  AdHoP TRT engine over best-candidate correspondences, re-runs RANSAC
  on the perspective-preconditioned set, and emits an enriched
  MatchResult with refinement_label="adhop".
- Invariant 4 passthrough fall-through: any RefinerBackboneError (TRT
  failure, OOM, NaN, bad shape) is caught, logged ERROR, FDR-emitted
  with error: true, and converted to passthrough that still counts
  against the rolling invocation-rate window. MemoryError and other
  non-listed exceptions propagate by design (AC-5 closed-set
  semantics).
- Rolling 60-s invocation-rate window + rate-limited WARN log
  (configurable via ratelimited_warn_window_ns; default 60 s).

Shared changes:
- C3MatcherConfig + C3_5RefinerConfig extended with the new
  weights/threshold/window fields.
- matcher_factory + refiner_factory optionally forward clock +
  fdr_client to the strategy's create(); backward-compatible.
- fdr_client.records registers five new kinds: matcher.frame_done,
  matcher.backbone_error, matcher.insufficient_inliers,
  matcher.all_failed, refiner.frame_done.

Tests: 66 new (43 C3 parametrised + 23 AdHoP) covering 47/47 ACs;
focused suite green; full project test suite green except for one
pre-existing flaky CLI cold-start timing test unrelated to this batch.

Oleksandr Bezdieniezhnykh 06f655d8fb [AZ-335] C1 warm-start hint persistence + F8 reboot recovery wiring 
Adds JsonSidecarWarmStartHintStore (atomic JSON + SHA-256 sidecar via
AZ-280) inside c1_vio, plus the cross-strategy WarmStartWiredStrategy
wrapper + prime_warm_start_from_disk / prime_warm_start_from_fc hooks
at runtime_root. AC-7 post-reset covariance inflation and AC-8 "no
fake confidence" baseline floor are enforced at the wiring layer so
no strategy module needed edits. Adds three c1_vio config fields
(warm_start_store_dir, warm_start_save_period_frames,
post_reset_covariance_inflation_factor) and registers the new FDR
kind vio.warm_start. 34 unit tests cover all 10 ACs + 3 NFRs.

Verdict PASS_WITH_WARNINGS — see
_docs/03_implementation/reviews/batch_56_review.md for the four
non-blocking documentation findings (F1 cold-start log kind shorthand,
F2 strategy-frame pose semantics, F3 dev-hardware perf smoke, F4
runtime_root importing c1-internal _facade_spine for shared FDR
conventions).

Closes AZ-335; depends on AZ-528 (batch 55).

Oleksandr Bezdieniezhnykh f12789ebf0 [AZ-528] Consolidate c1_vio strategy facade orchestration spine 
Replace 3-way byte-equivalent orchestration-spine duplication across
okvis2.py / vins_mono.py / klt_ransac.py with a single c1-internal
helper at components/c1_vio/_facade_spine.py. Closes cumulative
review batches 52-54 Finding F1. No behaviour change — all existing
AZ-332 / AZ-333 / AZ-334 AC tests pass unmodified (114 c1_vio tests
green, 237 with adjacent regression suite).

The helper exposes 5 stateless free functions (now_iso, bias_norm,
se3_from_4x4, frame_ts_ns, frame_image) and a FacadeSpine mixin
class providing _classify_state / _tick_lost / _emit_transition.
Concrete strategies inherit the mixin and set spine-required
instance attributes in __init__. Mirrors the AZ-527 precedent for
c2_vpr-side _assert_engine_output_dim consolidation.

New test file test_az528_facade_spine.py covers AC-1..AC-8 with 19
tests, including an AST regression guard that prevents future
re-introduction of the consolidated free functions in any strategy
module, plus a Risk-1 static check that every strategy's __init__
assigns every spine-required attribute.

Archive AZ-528 task spec to done/, bump autodev state to batch 56.

Oleksandr Bezdieniezhnykh ceb24b5a62 [AZ-334] C1 KLT/RANSAC strategy — engine-rule simple-baseline VIO 
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.

Oleksandr Bezdieniezhnykh 6a5954bdae [AZ-333] C1 VINS-Mono strategy — research-only comparative VIO 
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).

Oleksandr Bezdieniezhnykh 235eb4549e [AZ-527] Consolidate _assert_engine_output_dim into c2-internal helper 
Closes cumulative review batches 49-51 Finding F1 (Medium /
Maintainability) -- the 7-way duplication of _assert_engine_output_dim
across c2_vpr secondary VPR strategy modules.

Add c2-internal helper assert_engine_output_dim(inference_runtime,
handle, preprocessor, descriptor_dim, *, output_key='embedding',
input_key='input') in src/gps_denied_onboard/components/c2_vpr/
_engine_dim_assertion.py. The helper runs a zero-init dry-run
inference at preprocessor.input_shape() and asserts the engine output
dict carries (1, descriptor_dim) under output_key. Raises
gps_denied_onboard.config.schema.ConfigError on mismatch (preserving
the prior error envelope and message wording byte-identically).

Migrate 7 strategy modules (ultra_vpr, net_vlad, mega_loc, mix_vpr,
sela_vpr, eigen_places, salad) to import the helper and delete the
local _assert_engine_output_dim definitions + their inline
'AZ-527 (planned)' comments. NetVLAD is the only call site that
overrides output_key='vlad_descriptor'; the other 6 explicitly pass
output_key=_OUTPUT_KEY + input_key=_ENGINE_INPUT_KEY (matching helper
defaults but documenting strategy contract at the call site).

Add tests/unit/c2_vpr/test_az527_engine_dim_assertion.py (14 tests,
AAA pattern, Protocol-conforming fakes) covering AC-1..AC-4: helper
signature; wrong shape raises ConfigError naming both dims; missing
output key raises ConfigError naming the missing key; AST-walk
regression guard for stray definitions outside the helper module
(modeled on AZ-526's test_ac4_az526_no_module_level_iso_ts_from_clock_outside_helper);
import-grep regression guard verifying all 7 strategy modules import
the helper.

AC-5 (existing AZ-337/338/339/340 AC-6 sub-tests pass unmodified) is
exercised transitively: c2_vpr/ full directory 230/230 PASS, no test
file modified outside the new test_az527_*. AC-6 (AZ-270 + AZ-507
layer lints) verified by tests/unit/test_az270_compose_root.py
8/8 PASS.

Code-review verdict: PASS (zero findings). Ruff clean.

Oleksandr Bezdieniezhnykh 87909cce9f [AZ-340] C2 SelaVPR + EigenPlaces + SALAD secondary VPR backbones 
Three new VprStrategy implementations for IT-12 comparative-study
(research binary only, gated OFF for airborne / operator-tooling per
ADR-002). All run via the C7 TensorRT runtime (or ONNX-RT fallback)
with their own concrete BackbonePreprocessor, single-stage L2
normalisation, and FaissBridge-delegated retrieval — same pattern as
AZ-339 (MegaLoc + MixVPR), parametrised in tests for compactness.

  * SelaVprStrategy   — D=512,  input 224x224
  * EigenPlacesStrategy — D=2048, input 480x480
  * SaladStrategy     — D=8448, input 322x322 (DINOv2-Large backbone;
                        heaviest in the C2 family — NFR-perf budget
                        relaxed to 120 ms p95 / 1200 MB GPU per task
                        spec)

The composition-root factory tables and KNOWN_STRATEGIES set were
already pre-wired at AZ-336 land time; module-layout.md already names
all three Internal entries and BUILD_VPR_* rows. No CMake change
required (env-flag gating).

54 unit tests (3 strategies * 18 cases) cover AC-1..AC-11 plus extras
(single-stage L2, NCHW FP16, constructor validation, FDR emission).
All pass; sibling c2_vpr suite + composition-root regression + AZ-526
iso-ts regression all green.

Code review verdict: PASS_WITH_WARNINGS. Two Low findings logged in
batch_51_review.md: F1 escalates `_assert_engine_output_dim`
duplication from 4-way to 7-way (already tracked by AZ-527 hygiene
PBI; will surface in cumulative review batches 49-51); F2 mirrors the
AZ-337 / 338 / 339 AC-10 spec-drift precedent (literal
ConfigurationError vs implemented ConfigError / StrategyNotAvailable).

Oleksandr Bezdieniezhnykh 0d65ff4705 [AZ-339] C2 MegaLoc + MixVPR secondary VPR backbones 
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

Oleksandr Bezdieniezhnykh 5441ea2017 [AZ-508] Consolidate _iso_ts_now into helpers/iso_timestamps 
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

Oleksandr Bezdieniezhnykh 3c4fd272f1 [AZ-337] C2 UltraVPR primary backbone VprStrategy 
UltraVPR is the Documentary Lead's PRIMARY backbone per
description.md § 1 and is wired by default
(config.c2_vpr.strategy = "ultra_vpr"). Runs on the C7 TensorRT
runtime (AZ-298) or ONNX-Runtime fallback (AZ-299); explicitly NOT
on the PyTorch FP16 runtime so a TRT engine compile bug can fall
back to NetVLAD without simultaneously breaking both strategies.

Production changes:
- c2_vpr/ultra_vpr.py - UltraVprStrategy + module-level create()
  factory. embed_query pipeline: preprocess -> runtime.infer ->
  single-stage L2 -> VprQuery. retrieve_topk delegates one-line to
  FaissBridge. Engine load + output-shape assertion happen at
  create() time (AC-6) so misconfiguration surfaces at startup,
  not 17 minutes into a flight. UltraVPR has D=512 fixed (NOT a
  config knob; AC-5 / AC-6 / AC-7 all assume 512). Single-stage L2
  (no intra-cluster step like NetVLAD; spy-test enforces this so a
  future refactor cannot silently regress recall).
- c2_vpr/_preprocessor_ultra_vpr.py - centre-crop using the camera
  calibration's principal point (cx, cy from intrinsics_3x3),
  falling back to geometric centre + WARN log when calibration is
  absent (AC-9). Resize -> (384, 384) -> ImageNet mean/std ->
  FP16 NCHW.
- No composition-root changes: UltraVPR consumes a pre-compiled
  .trt engine (no PyTorch nn.Module), so the strategy module does
  NOT expose MODEL_NAME / architecture_factory. The composition-
  root _register_strategy_architecture helper no-ops cleanly for
  this case (verified by test_create_does_not_register_pytorch_architecture).

Tests:
- tests/unit/c2_vpr/test_ultra_vpr.py - 29 tests covering all 12
  ACs + preprocessor contract + constructor validation + FDR
  record emission + single-stage L2 enforcement.

Full unit suite: 1637 passed / 80 env-skipped (+29 new tests).
Per-batch code review (batch_47_review.md): PASS_WITH_WARNINGS
(3 Low-severity findings; no Critical / High / Medium):
- F1: _iso_ts_from_clock is now the 7th copy (AZ-508 will close).
- F2: AZ-337 spec uses outdated C7 API names; affects upcoming
  AZ-339 / AZ-340. Spec-hygiene PBI recommended.
- F3: principal-point fallback uses (0, 0) zero-detection for
  missing calibration; safe but tightens when intrinsics become
  Optional.

Architectural notes:
- AZ-507 layering clean. Imports only InferenceRuntimeCut,
  DescriptorIndexCut, c2_vpr internals, _types, helpers,
  clock, fdr_client. Architecture lint test passes.
- Pattern parity with NetVLAD (B46) where semantics permit;
  UltraVPR-specific paths (single-stage L2, 'embedding' output
  key, TRT runtime, no architecture registry, principal-point
  crop) are clearly localised.

Oleksandr Bezdieniezhnykh af0dbe863a [AZ-338] [AZ-283] C2 NetVLAD mandatory simple-baseline VprStrategy 
NetVLAD is the C2 comparative baseline per the engine rule (every
production-default backbone ships with a simple-baseline alongside).
Runs on the C7 PyTorch FP16 runtime (NOT TRT) so a TRT engine compile
bug cannot simultaneously break NetVLAD AND UltraVPR.

Production changes:
- c2_vpr/net_vlad.py — NetVladStrategy + module-level create() factory.
  Constructor wires InferenceRuntimeCut + DescriptorIndexCut +
  NetVladBackbonePreprocessor + DescriptorNormaliser + FaissBridge.
  embed_query pipeline: preprocess -> runtime.infer -> dual-stage
  normalisation (intra-cluster THEN global L2) -> VprQuery.
  retrieve_topk delegates one-line to FaissBridge.
- c2_vpr/_net_vlad_architecture.py — Arandjelovic et al. 2016 NetVLAD
  layer over torchvision VGG16 features + optional Linear PCA
  projection to descriptor_dim (default 4096; published Pittsburgh
  reference uses K*D=64*512=32768 raw + Linear(32768, 4096) PCA).
- c2_vpr/_preprocessor_net_vlad.py — OpenCV-based image preprocessor:
  decode -> centre-crop square -> resize (480, 480) -> ImageNet
  normalisation -> FP16 NCHW. Calibration is not consumed (NetVLAD
  is calibration-agnostic per published preprocessing chain).
- c2_vpr/inference_runtime_cut.py — NEW AZ-507 consumer-side cut
  mirroring C7 InferenceRuntime; lets c2_vpr stay AZ-507-clean.
- c2_vpr/config.py — added netvlad_descriptor_dim: int = 4096 knob.
- helpers/descriptor_normaliser.py — added intra_cluster_normalise
  (DescriptorNormaliser v1.0.0 -> v1.1.0; backward-compatible add).
- runtime_root/vpr_factory.py — added _register_strategy_architecture
  helper that binds (MODEL_NAME, architecture_factory(descriptor_dim))
  to C7's architecture registry before delegating to the strategy's
  create() factory. Keeps the c7 import at L4, preserves AZ-507.
- fdr_client/records.py — registered vpr.embed_query,
  vpr.backbone_error, vpr.preprocess_error record kinds.

Tests:
- tests/unit/c2_vpr/test_net_vlad.py — 31 tests covering all 11 ACs +
  preprocessor contract + architecture factory + constructor
  validation + FDR record emission.
- tests/unit/test_az283_descriptor_normaliser.py — +8 tests for the
  new intra_cluster_normalise.
- tests/unit/test_az272_fdr_record_schema.py — +3 fixture payloads.

Full unit suite: 1608 passed / 80 env-skipped (+43 new tests).
Per-batch code review (batch_46_review.md): PASS_WITH_WARNINGS
(4 Low-severity hygiene findings; no Critical/High/Medium).

Architectural notes:
- The spec implied c2_vpr.net_vlad.create() registers the architecture
  with C7. That violates AZ-507 (no cross-component imports). Resolved
  by exposing MODEL_NAME + architecture_factory(descriptor_dim) on the
  strategy module and having the composition root perform the C7 bind.
- C7 PyTorch runtime API names in the spec (forward, load_engine)
  were outdated; aligned implementation with the live v1.0.0 Protocol
  (infer, compile_engine + deserialize_engine). Spec hygiene flagged
  in review F2.

Oleksandr Bezdieniezhnykh 88f6ae6dce [AZ-341] C2 FAISS HNSW retrieve wiring (FaissBridge + AZ-507 cut) 
Shared retrieve_topk plumbing for every concrete C2 VprStrategy:
- FaissBridge centralises the c6 search_topk → VprResult pipeline,
  the defended-in-depth INV-4 check (exactly k, distance-ascending),
  the WARN-threshold check on distances[0], optional per-frame DEBUG
  log, and one `vpr.retrieve_topk` FDR record per call with latency
  measurement.
- DescriptorIndexCut Protocol — consumer-side structural cut of c6
  DescriptorIndex.search_topk (AZ-507); keeps c2_vpr c6-import-free.
- C2VprConfig gains warn_top1_threshold + debug_per_frame_distances
  knobs with validators.
- KNOWN_PAYLOAD_KEYS registers vpr.retrieve_topk for the FDR record
  schema with payload {frame_id, backbone_label, top10_distances,
  latency_us}; companion fixture added to the AZ-272 roundtrip suite.
- 22 unit tests cover AC-1..AC-11 + NFR-perf microbench (p95 ≤ 0.5 ms)
  + constructor and retrieve-argument validation.

Verdict: PASS_WITH_WARNINGS (2 Low findings — duplicated ISO-ts
helper across c2/c5/c11/c12, captured in AZ-508 hygiene PBI;
spec-listed but unused `normaliser` parameter dropped — INV-3 makes
the embedding L2-normalised at the strategy's `embed_query`).

Tests: 1565 passed / 80 skipped (was 1543; +22 new tests).

Oleksandr Bezdieniezhnykh 5fe67023b2 [AZ-329] [AZ-330] [AZ-523] [AZ-524] Batch 44 atomic refactor 
Implements two new C12 services and rebalances the C11/C12 boundary
in one atomic commit:

* AZ-329 PostLandingUploadOrchestrator — gates C11 upload on the
  `flight_footer` FDR record's `clean_shutdown` field; 4 refusal
  modes; new FdrFooterReader Protocol + LocalFdrFooterReader.
* AZ-330 OperatorReLocService — AC-3.4 visual-loss re-localization
  hint; reuses shared LatLonAlt; OperatorCommandTransport Protocol
  cut (E-C8 owns the future pymavlink concrete); new FDR record
  kind `c12.reloc.requested`; log redaction (lat/lon 5 decimals,
  reason 200 chars).
* AZ-523 C11 internal flight-state gate removed (SRP refactor):
  `confirm_flight_state` / `FlightStateSignal` use /
  `FlightStateNotOnGroundError` deleted from C11; TileUploader
  contract bumped to v2.0.0 (frozen) with migration note; AZ-317
  superseded.
* AZ-524 Package rename `c12_operator_tooling` →
  `c12_operator_orchestrator` across source, tests, pyproject,
  CMake, Dockerfile, compose, CI, runtime-root services class
  (`OperatorOrchestratorServices`) + factory function
  (`build_operator_orchestrator`), logger namespaces, config slug,
  docs, and the E-C12 epic title.

Tests: 1543 passed, 80 skipped (all environment gates). Targeted
AC suite (AZ-329 + AZ-330 + FdrFooterReader): 37 passed. Cold-start
NFR-perf still ≤ 500 ms p99.

Tracker: AZ-317 → Done (superseded); AZ-319 v2.0.0 contract bump
comment; AZ-329/AZ-330 → In Testing; AZ-253 epic renamed; AZ-523
+ AZ-524 created and closed as audit-trail tickets.

See `_docs/03_implementation/batch_44_cycle1_report.md`.

Oleksandr Bezdieniezhnykh 7644b25e8c [AZ-328] C12 BuildCacheOrchestrator + remote C10 invoker (Batch 43) 
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.
