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.

### NFT-LIM-01: Jetson memory ≤ 8 GB throughout 8 h replay
|
|
|
|
**Summary**: Validates AC-4.2 — memory < 8 GB shared on Jetson Orin Nano Super for the full duty cycle.
|
|
**Traces to**: AC-4.2, RESTRICT-HW-1
|
|
|
|
**Preconditions**:
|
|
- Tier-2 only (Jetson hardware).
|
|
- `tile-cache-fixture` mounted.
|
|
- 8 h Derkachi replay loop (~60 loops of the 490 s fixture, OR a wrapped 8 h synthetic load that holds the same operating mix per AC-NEW-3 8 h synthetic-load definition).
|
|
|
|
**Monitoring**:
|
|
- `jetson_stats` (`jtop` API) RAM usage sampled at 1 Hz.
|
|
- Per-component memory annotation if SUT exposes it via `NAMED_VALUE_FLOAT` / FDR.
|
|
- Swap usage (must remain 0 — Jetson Orin Nano Super has no swap by default).
|
|
|
|
**Duration**: 8 h.
|
|
|
|
**Pass criteria**: Peak RSS ≤ 8 GB across the entire 8 h window; swap stays 0.
|
|

### NFT-LIM-02: FDR ≤ 64 GB / flight (8 h synthetic load)
|
|
|
|
**Summary**: Validates AC-NEW-3 — per-flight FDR ≤ 64 GB; oldest segment dropped on rollover; no payload class silently dropped without a logged rollover.
|
|
**Traces to**: AC-NEW-3
|
|
|
|
**Preconditions**:
|
|
- Tier-1 acceptable (storage budget is policy/rotation driven, not Jetson-specific).
|
|
- `fdr-output` Docker volume sized exactly 64 GB.
|
|
- 8 h Derkachi replay loop at 3 Hz nav frames (per AC-NEW-3 validation wording).
|
|
|
|
**Monitoring**:
|
|
- Total `fdr-output` volume size at 1-min sample rate.
|
|
- Per-payload-class size: per-frame estimates + IMU traces + emitted MAVLink + raw MAVLink (tlog) + system health + mid-flight tiles + ≤0.1 Hz failed-tile-gen thumbnails.
|
|
- Rollover-event log entries (count, timestamp, dropped-segment ID).
|
|
|
|
**Duration**: 8 h synthetic.
|
|
|
|
**Pass criteria**:
|
|
- Volume never exceeds 64 GB.
|
|
- Every drop event has a corresponding rollover log entry (no silent drops).
|
|
- All payload classes enumerated in AC-NEW-3 are present (no class missing entirely).
|
|

### NFT-LIM-03: Tile cache ≤ 10 GB across operational area
|
|
|
|
**Summary**: Validates RESTRICT-SAT-2 — cache budget 10 GB persistent across the ~400 km² operational area, including manifests, overviews, and any precomputed indices.
|
|
**Traces to**: RESTRICT-SAT-2, AC-8.3
|
|
|
|
**Preconditions**:
|
|
- `tile-cache-fixture` covers the full operational-area footprint (still-image + Derkachi route bbox, target ~400 km² for parity).
|
|
|
|
**Monitoring**:
|
|
- Total tile-cache size on disk.
|
|
- Per-component breakdown: tile filesystem, tile manifest DB (PostgreSQL btree per `solution.md`), FAISS HNSW index, descriptor cache.
|
|
|
|
**Duration**: one-shot measurement after fixture build + after a 5 min replay (to catch any descriptor-on-demand growth).
|
|
|
|
**Pass criteria**: Total cache size ≤ 10 GB at both measurement points.
|

### NFT-LIM-04: No thermal throttling at 25 W TDP — workstation thermal-day baseline
|
|
|
|
**Summary**: Tier-2 baseline of AC-NEW-5 thermal-throttle behavior at workstation ambient temperature. Full chamber test at +50 °C is deferred to the AC-NEW-5 chamber gate (out-of-scope for data-acquisition per Phase 1 gate).
|
|
**Traces to**: AC-NEW-5 (PARTIAL), RESTRICT-HW-1
|
|
|
|
**Preconditions**:
|
|
- Tier-2 (Jetson) at workstation ambient (~25 °C).
|
|
- 8 h Derkachi replay loop sustaining 25 W TDP.
|
|
|
|
**Monitoring**:
|
|
- `tegrastats`: GPU/CPU clock, GR3D_FREQ, RAM, temperatures, power-rail draw, throttle events.
|
|
|
|
**Duration**: 8 h.
|
|
|
|
**Pass criteria**:
|
|
- 0 thermal throttle events at workstation ambient.
|
|
- Average power draw ≤ 25 W.
|
|
- Hot-soak chamber test at +50 °C is OUT OF SCOPE for data-acquisition; tracked as deferred AC-NEW-5 chamber gate. The test is expected to be exercised on a chamber-attached Jetson runner before any release tag.

### NFT-LIM-05: Disk storage budget (cache 10 GB + FDR 64 GB)
|
|
|
|
**Summary**: Validates the combined storage budget per `restrictions.md` § Onboard Hardware: ≥ tile cache (~10 GB) + per-flight FDR (64 GB) of available storage on the deployed Jetson.
|
|
**Traces to**: RESTRICT-HW-1 (storage budget)
|
|
|
|
**Preconditions**:
|
|
- Tier-2 acceptance run on the deployed-image Jetson.
|
|
|
|
**Monitoring**:
|
|
- Available storage on the production storage device after a single fresh install of SUT + fixtures.
|
|
|
|
**Duration**: one-shot.
|
|
|
|
**Pass criteria**: Available storage ≥ 74 GB after install, leaving headroom for system + logs.
