Enhance skill discipline and clarify acceptance criteria and restrictions

Browse Source 
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
> Last revised 2026-05-07 (cleanup pass: stripped algorithm/library/parameter implementation details; renamed source label `vo_extrapolated` → `visual_propagated`; broadened FC scope to ArduPilot + iNav). See git history for prior versions.

> Subsequent revision 2026-05-07 (post-SQ6 research): AC-4.3 reworded to acknowledge that no single message type is accepted by both ArduPilot Plane and iNav — per-FC interface is named explicitly (MAVLink `GPS_INPUT` for ArduPilot Plane, MSP2 `MSP2_SENSOR_GPS` for iNav). Rationale and L1 sources in `_docs/00_research/02_fact_cards.md` SQ6 / `_docs/00_research/01_source_registry.md` Sources #4, #9, #10, #12, #13.

## Position Accuracy
- **AC-1.1** — Frame-center GPS within **50 m** of true GPS for **≥80%** of normal-flight photos.

## Real-Time Onboard Performance
- **AC-4.1** — End-to-end latency (camera capture → GPS to FC) **<400 ms p95**. Up to ~10% frames may drop under sustained load.
- **AC-4.2** — Memory **<8 GB shared** on Jetson Orin Nano Super.
- **AC-4.3 — FC output contract**: WGS84 coordinates over MAVLink, via the standard external-positioning message type(s) accepted by ArduPilot and iNav. Honest covariance carried in the field the FC uses for outlier rejection (under-reported covariance is a defect, see AC-NEW-4). Source-label semantics per AC-1.4. Implementation may emit a primary GPS-substitute message and, when the estimator delivers full 6-DoF covariance + quality above a configured threshold, an optional auxiliary external-odometry message. Per-FC message selection and FC-side parameter wiring are design decisions.
- **AC-4.3 — FC output contract**: WGS84 coordinates delivered to each supported FC via that FC's documented external-positioning interface — MAVLink `GPS_INPUT` for ArduPilot Plane, MSP2 `MSP2_SENSOR_GPS` for iNav. Honest covariance is carried in the field each FC uses for outlier rejection (under-reported covariance is a defect, see AC-NEW-4). Source-label semantics per AC-1.4 are emitted out-of-band via the FC-appropriate channel (e.g. MAVLink `STATUSTEXT` / `NAMED_VALUE_FLOAT` for ArduPilot; MSP equivalent for iNav). Where the FC supports it, implementation may also emit an optional auxiliary external-odometry message when the estimator delivers full 6-DoF covariance + quality above a configured threshold. Per-FC parameter wiring (EKF source-set selection on ArduPilot; GPS provider / UART role on iNav), FDR-side message variants, and out-of-band channel choice remain design decisions.
- **AC-4.4** — Estimates streamed frame-by-frame; no batching/delay.
- **AC-4.5** — System may refine prior estimates and emit corrections.
