Closes the trust-chain gap where an ~11 KB per-room LoRA adapter (ADR-150
section 3.4) could silently change inference without the witness noticing:
provenance carried only "rfenc-v<N>" with no notion of adapter identity.
- StreamingEngine::set_room_adapter(AdapterInfo): pins the adapter's
content-derived id into provenance model_version
("rfenc-v1+adapter:<id>") — and therefore into the BLAKE3 witness — so
swapping or clearing adapter weights always shifts the witness. Engine test
proves base -> adapter -> other-adapter -> cleared all witness differently
and cleared == base.
- RecalibrationAdvisor: recommends re-running the ADR-135 empty-room baseline
/ refitting the room adapter on sustained low fusion coherence (streak
threshold, default 60 cycles ~ 3 s at 20 Hz) or an ADR-142 change-point.
Surfaced as TrustedOutput::recalibration_recommended, stored on the
sensing-server AppState alongside the witness at both live fusion sites.
- Bridge plumbing: EngineBridge::{set_room_adapter, clear_room_adapter} +
live-path test that the adapter id flows into the live witness.
Scope note (honest): this is the deployable provenance/trigger half of the
"retrained model" roadmap item. Fitting the adapter itself runs in the
existing external calibration service (aether-arena/calibration/); a trained
RF-encoder checkpoint still does not exist in-tree.

StreamingEngine::process_cycle appended one SemanticState belief per cycle
with no eviction — ~1.7M nodes/day at 20 Hz (beyond-SOTA roadmap finding #6).
Add WorldGraph::prune_semantic_states(max): deterministic eviction of the
oldest beliefs by (valid_from_unix_ms, id); structural nodes (rooms, zones,
sensors, anchors, tracks, events) are never eligible. Wire it into the
engine after each belief append (DEFAULT_SEMANTIC_RETENTION = 7,200, ~6 min
at 20 Hz; set_semantic_retention to tune). The WorldGraph holds current
beliefs; durable history is the recorder's job, so no audit data is lost.
3 new tests: end-to-end bounded growth, oldest-only eviction, deterministic
equal-timestamp tie-break. Workspace gate: 2,865 passed, 0 failed.
