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
(cmake, actionlint).

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.
Full unit-test sweep: 791 passed, 2 pre-existing environment skips.

F1 (High/Architecture) from cumulative review of batches 01-22:
`ISam2GraphHandleImpl` did not satisfy C4's `ISam2GraphHandle`
Protocol stub (AZ-355) because it lacked `get_pose_key`.
`pose_factory`'s isinstance gate would have raised at composition.
Two Protocols (C4 minimal consumer cut, C5 richer producer surface)
are intentional per AZ-355 Risk 1 — the impl just needed to expose
the canonical name. Delegates to estimator.key_for_frame.
Added cross-component conformance test asserting the C5 impl
satisfies both Protocols, so future drift trips a unit test.
F2 (Medium/Maintainability): added justifying comments at four
`except: pass` sites in runtime_root, c8_fc_adapter (ap + inav),
and c13_fdr writer. No behavioral change.
Updated cumulative review report verdict from FAIL to PASS and
recorded a post-mortem on the initial misframing
(treated the dual-Protocol design as duplication on first read).
Autodev state: batch 22 done, cumulative-review PASS,
ready for batch 23.

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},
gps_bounded_delta.{accept,reject}) registered in AZ-272 schema.
- 33 new unit tests cover AC-1..AC-15; full repo 750 passed / 2
skipped (pre-existing CI tooling skips).
Docs synced: protocol contract, C5 component description,
architecture, glossary, system-flows, C10 provisioning description.

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

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.
Co-authored-by: Cursor <cursoragent@cursor.com>
Implements Invariants 5 + 8 + AC-NEW-2 / AC-NEW-8: the
EstimatorOutput.source_label now reflects a real state machine
(DEAD_RECKONED → SATELLITE_ANCHORED ↔ VISUAL_PROPAGATED) governed by
a spoof-promotion gate that latches closed on FC SPOOFED GPS health
and re-opens only when BOTH conditions hold — ≥10 s
STABLE_NON_SPOOFED AND next anchor within
spoof_promotion_visual_consistency_tol_m.
Every reject emits a c5.state.spoof_rejected FDR record plus a
subscriber-fan-out STATUSTEXT (severity WARNING, 50-char cap per
MAVLink). FDR and subscriber paths bypass the standard logger so
silencing logs cannot suppress the spoof trail (R07 / AC-6).
GtsamIsam2StateEstimator now eagerly builds the SM from C5StateConfig
in __init__; new public methods notify_gps_health() (delegates to
SM, called by composition root from C8 inbound) and
subscribe_spoof_rejection() (composition root attaches C8's
QgcTelemetryAdapter here). health_snapshot.spoof_promotion_blocked
+ current_estimate.source_label now flow from the live SM.
25 new unit tests across all 12 ACs plus cancellation, subscriber
exception isolation, and estimator wire-up integration cases. One
AZ-384 test renamed + updated to expect DEAD_RECKONED before any
anchor (was VISUAL_PROPAGATED placeholder pre-AZ-385).
Full suite: 632 passed, 2 skipped.

Implements Invariant 9 / AC-5.2: when current_estimate cannot return a
fresh output for >= state.no_estimate_fallback_s (default 3.0 s), emit
ONE engagement signal (FDR kind=c5.state.no_estimate_fallback_engaged
+ GCS STATUSTEXT severity CRITICAL); on recovery, ONE recovery signal
(FDR kind=c5.state.no_estimate_fallback_recovered + STATUSTEXT NOTICE).
Rate-limited via single _in_fallback latch (AC-2: 30 s sustained
no-estimate still emits exactly one engagement).
New FallbackWatcher class owns the state machine; estimator wires it
through constructor + current_estimate entry/success hooks. Public
check_fallback_state(now_ns) watchdog (NFR p99 <= 5 us) + subscribe
APIs let C8 outbound react without coupling C5 to a concrete GCS
adapter at construction. Severity enum extended with CRITICAL=2 and
NOTICE=5 to match MAVLink MAV_SEVERITY.
18 new unit tests across all 8 ACs, deterministic synthetic clock,
integration tests patch monotonic_ns through GtsamIsam2StateEstimator
to drive AC-7 iSAM2 leg (ESKF leg deferred to AZ-386).
Full suite: 607 passed, 2 skipped.

Replaces the last three NotImplementedError placeholders on
GtsamIsam2StateEstimator with real Marginals + output methods:
- current_estimate(): recovers the 6x6 Marginals covariance for the
most-recently committed pose key, enforces the SPD invariant via
np.linalg.cholesky (Invariant 10), converts the local-ENU pose
translation to WGS84 via the shared WgsConverter, derives a
body->world quaternion, and emits a fresh EstimatorOutput
(smoothed=False, Invariant 4). On SPD failure transitions
isam2_state -> LOST and raises EstimatorFatalError (AC-5.2 path).
- smoothed_history(n): iterates the smoother's active POSE keys via
_smoother.calculateEstimate().keys() (filtered by GTSAM symbol
char) and the smoother timestamps via ts_map.at(key) - workaround
for the pinned gtsam_unstable build's non-iterable
FixedLagSmootherKeyTimestampMap. Bounded by K (Invariant 6); every
entry has smoothed=True (Invariant 7).
- health_snapshot(): cheap O(1) accumulator read; reports
IsamState lifecycle, pose-key count, AC-NEW-8
cov_norm_growing_for_s rolling 60s deque-backed counter, and
spoof_promotion_blocked via the AZ-385 state machine injection
point.
Adds two public injection points for AZ-385/composition root:
set_enu_origin(LatLonAlt) and attach_source_label_state_machine(machine).
Defaults: (0, 0, 0) ENU origin, VISUAL_PROPAGATED source label,
spoof_promotion_blocked=False.
Wires _record_committed_pose_key into the three add_* success paths
so current_estimate only reads keys that have real values in iSAM2.
The JACOBIAN path in add_pose_anchor deliberately skips this call -
Invariant 3 keeps the JACOBIAN pose out of the iSAM2 graph.
Tests: +27 in tests/unit/c5_state/test_az384_marginals_outputs.py
covering all 10 ACs. Three obsolete AZ-382 tests
(test_ac10_*_raises_named_az384) removed. Full suite: 589 passed,
2 skipped.
Co-authored-by: Cursor <cursoragent@cursor.com>
Replaces AZ-382 NotImplementedError placeholders with real GTSAM factor
adds wired against the iSAM2 graph handle:
- add_vio -> BetweenFactorPose3 between consecutive VIO pose keys
(first call primes the chain; AZ-388 owns first-keyframe seeding).
- add_pose_anchor -> mode-dispatch per pose.covariance_mode:
"marginals" -> PriorFactorPose3 + handle.update();
"jacobian" -> skip iSAM2 add per AZ-361 contract.
Both paths bump _last_anchor_ns via time.monotonic_ns().
- add_fc_imu -> shared ImuPreintegrator.integrate_window +
reset_for_new_keyframe; builds a CombinedImuFactor between the
prev/curr (X, V, B) keyframe triple. Introduces new 'v' (velocity)
and 'b' (bias) GTSAM key namespaces decoupled from the VIO/pose
frame_id mapping.
Invariant 2 - non-decreasing timestamps - enforced per call with
EstimatorDegradedError + c5.state.out_of_order log. Every successful
add emits a structured DEBUG *_ok log; every failure emits a
structured ERROR *_failed log and raises through the C5 error
hierarchy (R05).
Contract-vs-reality fix-ups also landed:
- StateEstimator Protocol: add_fc_imu(ImuWindow) - was incorrectly
annotated as ImuTelemetrySample by AZ-381.
- _last_anchor_ns semantics switched to monotonic_ns() to match
last_anchor_age_ms.
- create() factory back-wires the ISam2GraphHandle to the estimator
via the new attach_handle() method.
Tests: +21 in tests/unit/c5_state/test_az383_factor_adds.py covering
all 8 ACs with mock ISam2GraphHandle instances. Three obsolete
AZ-382 tests (test_ac10_add_*_raises_named_az383) removed. Full
suite: 565 passed, 2 skipped.

Adds the C8 inbound producer side:
- TelemetryRing[T]: bounded drop-oldest ring; first-overflow INFO log
+ monotonic dropped_count.
- SubscriptionBus + SubscriptionHandle: synchronous fan-out, lock-
released-before-callback to avoid deadlock; subscriber crash caught
+ DEBUG-logged so one bad subscriber cannot kill the decode loop.
- PymavlinkInboundDecoder: pymavlink-based AP decoder for RAW_IMU,
SCALED_IMU2, ATTITUDE, GPS_RAW_INT, GPS2_RAW, HEARTBEAT, STATUSTEXT.
Out-of-order drop (Invariant 7) per-kind WARN. STATUSTEXT spoofing
sentinel promotes subsequent GPS to GpsStatus.SPOOFED within 5 s.
AC-5.1 warm-start hint cached on first 3D+ fix; embedded into
every FlightStateSignal.
- Msp2InavInboundDecoder: YAMSPy-based iNav polling decoder for IMU /
attitude / GPS / flight-state. signed=False always (RESTRICT-COMM-2);
GpsStatus.SPOOFED is unreachable on iNav.
Adds yamspy>=0.3.3 + pyserial>=3.5 to pyproject.toml.
Tests: 443 pass / 2 skip / 0 fail (+33 in batch 9).
Contract: no drift on fc_adapter_protocol.md v1.0.0; this batch
implements the inbound producer side without changing signatures.

AZ-294: MidFlightTileSnapshotSink writes orthorectified tile JPEGs
atomically to flight_root/<flight_id>/tiles/<tile_id>.jpg, emits a
kind="mid_flight_tile_snapshot" pointer record, and evicts the oldest
tile when the per-flight 64 MiB cap is exceeded. Adds optional
frame_id to the snapshot payload (fdr_record_schema bump).
AZ-295: RecordKindPolicy with two paired gates:
- enforce_or_raise (producer-side) raises RawFrameWriteForbiddenError
for raw_nav_frame / raw_ai_cam_frame at the call site, defending
AC-8.5 / RESTRICT-UAV-4.
- gate_for_writer (writer-side) tumbling-window rate-caps
failed_tile_thumbnail records at <= 0.1 Hz; over-cap drops are
coalesced into kind="overrun" records with the originating
producer slug.
AZ-296: take_off() composition-root sequence with strict ordering
(writer.__init__ -> start -> open_flight -> fc_adapter.__init__ ->
fc_adapter.open). On FdrOpenError, logs ERROR record, calls
writer.stop(), prints the documented FATAL line to stderr, and
sys.exit(EXIT_FDR_OPEN_FAILURE=2). composition_root_protocol bumped
to v1.1.0 with the new constants + takeoff-sequence section.
29 new tests; full suite 356 passed / 2 skipped / 0 failures.
No new dependencies (stdlib only).

AZ-291 — FileFdrWriter: single writer thread draining every registered
FdrClient SPSC ring buffer to per-flight segment files; per-segment
size rotation; cross-process fcntl.flock filelock on flight_root;
ENOSPC degraded mode with rate-capped ERROR logs and one GCS alert.
AZ-292 — FlightHeader/FlightFooter dataclasses + open_flight /
close_flight lifecycle methods; four per-flight monotonic counters
(records_written, records_dropped_overrun, bytes_written,
rollover_count) reported by the footer; flight_id mismatch and
close-without-open are typed errors.
AZ-293 — CapacityCapPolicy (post-rotation hook): walks the flight
directory, drops the oldest CLOSED segment when total > cap (default
64 GiB), emits a kind="segment_rollover" record per drop. Never drops
the currently-open segment or segment 0 alone; cap_misconfigured path
logs ERROR + GCS alert. No config flag disables emission (C13-ST-01).
Schema: bumped fdr_record_schema flight_header / flight_footer payload
key sets to match the AZ-292 task spec (effective 1.0.0 -> 1.1.0; no
prior producer); KNOWN_PAYLOAD_KEYS updated. Added FdrWriterConfig
nested in FdrConfig (segment_size_bytes, batch_size, flight_cap_bytes,
debug_log_per_record).
Tests: 29 new unit tests (8 AC + 1 invariant per task); full suite
323 passed, 2 pre-existing skips, 0 regressions.

E-CC-HELPERS closes with the three remaining Layer-1 helpers and
E-CC-CONF closes with the env > YAML > defaults precedence test
gate. All four tickets ship with frozen public surfaces, hermetic
unit tests, and no upward (components.*) imports.
* AZ-271 — tests/unit/shared/config/test_precedence.py (5 ACs + smoke
test + helper that names the layer in failure messages).
* AZ-282 — helpers/ransac_filter.py: static RansacFilter +

median residual semantics pinned by contract.
* AZ-276 — helpers/imu_preintegrator.py + make_imu_preintegrator;
GTSAM PreintegratedCombinedMeasurements; strict-monotonic ts_ns
guard runs before any state mutation. Adjacent hygiene:
_types/nav.py ImuSample/ImuWindow now use ts_ns:int and the

* AZ-278 — helpers/lightglue_runtime.py: structural R14 fix.
LightGlueRuntime + non-blocking concurrent-access guard that

AZ-273: lock-free SPSC ring buffer with pre-allocated slots, power-of-
two capacity, opt-in SPSC guard, and EnqueueResult / FdrSpscViolationError
on the public surface. make_fdr_client caches one client per producer_id
and reads capacity from config.fdr.per_producer_capacity with fallback
to queue_size.
AZ-274: default_overrun_policy implements drop-oldest + retry + immediate
marker emission, with prior-marker dropped_count folding via _evict_one
so user-loss info is never lost across iterations. ERROR diagnostic is
rate-limited to <=1/sec per producer.
AZ-275: FakeFdrSink mirrors the FdrClient public surface and reuses the
production default_overrun_policy via a duck-typed _PolicyAdapter. The
test-only records/all_records_ever properties let component tests assert
both in-buffer and lifetime state. tests/conftest.py registers the
fake_fdr_sink fixture and an AST architecture lint forbids production
imports of fakes.
AZ-267: FdrLogBridgeHandler installs on the root logger via wire_log_bridge
and forwards only WARN+ERROR records into the FDR with kind="log".
Thread-local recursion guard short-circuits internal logging; saturated-
queue diagnostics go to stderr every N=1000 drops.
AZ-268: tests/contract/log_schema.py covers every row of the schema's
Test Cases table plus the "DEBUG+INFO never reach FDR" invariant.
pyproject.toml registers the contract pytest marker and the
contract-mandated log_schema.py file-name.
251 unit + contract tests pass (48 new). Review verdict:
PASS_WITH_WARNINGS; findings are NFR-perf deferrals + documented
relaxation of AZ-274 AC-2 coalescing under permanently-stalled consumer.

unknown payload + top-level fields and canonical overrun-record shape.
AZ-279: pyproj-backed WGS84/ECEF/ENU + OSM slippy-map tile math with
WgsConversionError for shape/range/zoom guards.

Closes out greenfield Step 6 (Decompose) for all 14 components
(C1-C13 + cross-cutting helpers/replay). Covers tasks AZ-266..AZ-446
plus the _dependencies_table.md and component contract documents.
State file updated to greenfield Step 7 (Implement), not_started.
Co-authored-by: Cursor <cursoragent@cursor.com>
Transitioned the autodev state to phase 21, reflecting the completion of Step 5 and the drafting of Step 6 epics. Revised the architecture documentation to clarify the roles of the Tile Manager and its components, ensuring accurate representation of the system's operational flow. Updated glossary entries for Flight State and Operator to incorporate recent changes and enhance clarity on component interactions and responsibilities.
Modified the autodev state to transition to phase 10, updating the sub-step name and details to reflect the latest architectural review changes. Enhanced the glossary entry for VioStrategy to clarify its functionality, build-time exclusions, and implications for deployment and research binaries, ensuring alignment with recent architectural decisions.
Enhanced the SKILL.md file to enforce conciseness rules for the state file, specifying acceptable content and file size limits. Updated the autodev state to reflect the transition to the planning phase, including changes to the current step and sub-step details. Revised acceptance criteria to clarify validation requirements and external dependencies, ensuring alignment with the latest research findings. Added a new overlay for Mode B revisions to track changes and decisions made during the assessment process.
Updated various documentation files to clarify the handling of splittable artifacts, allowing for folder equivalents of key markdown files when they exceed size limits. Adjusted references in multiple sections to reflect this new structure, ensuring consistency across the research methodology. Enhanced clarity on the saving actions and artifact organization, particularly for `01_source_registry.md`, `02_fact_cards.md`, and `06_component_fit_matrix.md`. This change aims to improve usability and maintainability of the research documentation.
Revised the autodev state to reflect the transition to phase 12, detailing the candidate enumeration for C1 (VIO) with a focus on context7 capability verification and restrictions assessment. Updated the source registry to indicate progress on C1 candidates, including the addition of new sources and their evaluation status. Enhanced fact cards with detailed assessments of VINS-Mono and VINS-Fusion, highlighting their suitability and licensing considerations for dual-use deployment. Deferred context7 verification and structured sub-matrix tasks to the next session.
Updated the meta-rule document to emphasize strict adherence to skill instructions, prohibiting unnecessary investigations or external checks. Revised acceptance criteria and restrictions to correct communication protocol details for ArduPilot and iNav, ensuring clarity on external-positioning interfaces. Adjusted autodev state to reflect ongoing research phase and updated sub-step details for improved tracking.
acceptance_criteria.md and restrictions.md were carrying internal
component selections (DINOv2/SuperPoint/FAISS/ESKF), library pins
(pymavlink/MAVSDK), autopilot parameter values (GPS1_TYPE=14,
EK3_SRC1_*, VISO_QUAL_MIN), and v1/v1.1 phasing tied to specific
ArduPilot PR numbers. Per IEEE 830 / Atlassian / GitScrum,
acceptance criteria must be design-independent — outcomes only,
not implementation. Cleaned both files (-35% combined size) while
preserving every testable threshold and contract bullet.
Output-schema label renamed: vo_extrapolated -> visual_propagated.
FC scope broadened from ArduPilot-only to ArduPilot + iNav (both
via standard MAVLink external-positioning interfaces).
Encoded the lesson into the two skills that write/refine AC:
- problem/SKILL.md (initial AC production)
- research/steps/01_mode-a-initial-research.md (Phase 1 AC
& Restrictions Assessment)
Autodev state reset to greenfield Step 2 (Research) for the
post-restart greenfield run; cycle 1, in-progress at sub-step
ac-restrictions-assessment.
