Prototype uncertainty-triggered virtual views with signed replay and acceptance gates

[ruvnet]

Why

Test whether exposing a hidden spatial relationship can help a frozen control policy before retraining it. This is a bounded research prototype motivated by SpatialHarness, not a reproduction of its robot results.

Changes

• Dependency-free CPU broker selecting complementary orthographic SVG views when target/reference uncertainty crosses a threshold.
• Fail-closed stale-scene, contact-transition, geometry-drift, uncertainty and deadline checks.
• In-memory Ed25519 signing and deterministic receipt verification/replay, with no actuator authority.
• Three-task evaluator requiring +20 percentage points on two tasks, no regression beyond five points, p95 below 150 ms, at least 95% pre-action drift detection and verified receipts.
• Cross-repository RuView adapter benchmark, ADR and validation report.

Validation

Local Node 24.19.0: 769 unit tests, 159 governance tests, typecheck/build/lint and edge/development-policy checks passed. Cross-repository benchmark: 1,000 synthetic 256-object scenes, p95 13.822 ms, 1,000/1,000 receipts replayed. Initial missing dependencies and historical oracle commit were restored before successful reruns.

Limits

Zero hardware trials. Robot gains, end-to-end latency and real drift recall remain INCONCLUSIVE. SVG box projections are conceptual; no tracker, reconstruction, physics or policy execution is supplied. Receipts authenticate planning content, not sensor truth or delivery/timing. Defaults unchanged; no deployment or promotion.

Companion RuView PR: ruvnet/RuView#2189

Merge preparation: patched source-map-js from 1.2.1 to 1.2.2 after CI identified GHSA-68fv-2mgg-jv7q. Local npm audit reports zero vulnerabilities; build and all nine broker tests pass. Hardware acceptance remains unverified.
