From f9c98809c2364df5f11acd909e010586615dcb7c Mon Sep 17 00:00:00 2001 From: ruv Date: Sun, 24 May 2026 22:16:02 -0400 Subject: [PATCH] =?UTF-8?q?feat(adr-124/phase4):=20BFLD=20tool=20family=20?= =?UTF-8?q?=E2=80=94=20bfld.last=5Fscan=20+=20bfld.subscribe=20(ADR-124=20?= =?UTF-8?q?=C2=A74.1)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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//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//subscribe?duration_s= - 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//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.
