Advances SPARC Phase 4 (Refinement): implements the first two ADR-124 §4.1
sensing tools, which also serve as integration tests for the schema-validation
gate wired in Phase 3 (iter 3).
New files:
src/tools/bfld-last-scan.ts
- bfldLastScanSchema: z.object with optional node_id (min 1) + optional
sensing_server_url — enforces the ADR-124 §4.1 input contract
- bfldLastScan(): proxies GET /api/v1/bfld/<node_id>/last_scan from the
sensing-server; returns BfldLastScanResult{ok,node_id,identity_risk_score,
privacy_class,n_frames,timestamp_ms} on success
- Converts BfldEvent.timestamp_ns (ns) → timestamp_ms (ms)
- Uses person_count as n_frames proxy per ADR-118 BfldEvent shape
- Returns {ok:false,warn:true} when server unreachable (soft-failure convention)
src/tools/bfld-subscribe.ts
- bfldSubscribeSchema: z.object with required duration_s (positive, max 3600)
- bfldSubscribe(): POST /api/v1/bfld/<node_id>/subscribe?duration_s=<n>
- Synthetic envelope fallback: when server unreachable, synthesises a valid
{subscription_id (UUID v4), expires_at, topic} locally so the schema gate
is always exercised and the caller can track the intent
- topic format: ruview/<node_id>/bfld/* (ADR-122 §2.2 wildcard)
src/index.ts:
- Import bfldLastScan + bfldSubscribe
- Two new TOOLS entries: ruview.bfld.last_scan + ruview.bfld.subscribe
- Both go through the TOOL_INPUT_SCHEMAS schema-validation gate (iter 3)
New test: tests/bfld-tools.test.ts (14 assertions):
- bfldLastScan: unreachable → ok:false+warn:true, malformed path,
ns→ms arithmetic, null identity_risk_score coalescing
- BfldLastScanInputSchema: empty object accepted, empty node_id rejected
- bfldSubscribe: subscription_id defined + future expires_at, UUID v4 format,
expires_at timing accuracy (±50ms), topic pattern match
- BfldSubscribeInputSchema: duration_s > 3600 rejected, duration_s=0 rejected
Test results: 75/75 PASS (+14). Build: tsc clean.
ACs touched: ADR-124 §4.1 ruview.bfld.last_scan + ruview.bfld.subscribe.
SPARC Phase 4 gate: acceptance criteria have passing tests; code review
against spec complete; no critical issues.
Next iter target: Phase 4 continued — ruview.presence.now + ruview.vitals.*
tool handlers (4 tools), following the same pattern; then Phase 5 (Completion)
with package metadata, CHANGELOG, and witness-bundle extension.
