test(calibration): full-loop integration test — baseline→enroll→train→infer proven in-process (ADR-151 §7 gap, software half)

Closes the software half of PR #989's headline validation gap: the
complete calibration loop had never run end-to-end anywhere, even
in-process. tests/full_loop.rs (412 lines, deterministic xorshift32
room simulator, HT20/52-subcarrier/20Hz, same fingerprint family as
the ADR-135 roundtrip test) now drives the CLI's exact stage order
through the public API:

  1. baseline  — 600 static frames, zero motion flags post-warmup,
                 calibration_uuid() exactly as the CLI derives it
  2. enroll    — all 8 AnchorLabel::SEQUENCE anchors through
                 AnchorQualityGate::default(), session is_complete()
  3. extract   — AnchorFeature::from_series recovers injected 0.25Hz
                 and 0.125Hz breathing within ±0.04Hz
  4. train     — SpecialistBank::train fits all 6 specialists; JSON
                 round-trip and the runtime consumes the RELOADED bank
  5. infer     — positive: never-enrolled 0.30Hz subject reads present,
                 18±2 BPM; negative: empty window reads absent;
                 degradation: foreign baseline_id flags STALE

Seed-robust (5 seeds), passes with and without default features:
36 unit + 1 integration green.

Validation docs updated (ADR-151 §7 + integration doc §7 matrix): what
remains is strictly the on-target hardware session (real CSI, physically
empty room, operator performing the guided anchors). Three behavioral
findings from building the test are recorded for pre-session triage:
z-band squeeze between baseline motion flagging (z>2.0) and the still-
anchor gate (presence_z≥1.5) — likeliest on-hardware enroll failure;
variance-only PresenceSpecialist missing motionless-person mean shift;
ungated breathing_hz/heart_hz in noise-window embeddings.

-**Current status (2026-06-09):** Stages 1–5 implemented with *statistical* specialists (threshold/prototype/autocorrelation). 54 unit tests (incl. multistatic), all passing under qemu-aarch64. **Validation scope is precise:** baseline capture + HTTP API + auth are proven on real CSI (Pi-5 nexmon, 6,813 frames; and an ESP32-S3). The one live runtime signal (breathing ~16–31 BPM via `room-watch`) used the *stateless* breathing head, **not** a trained bank; a clean empty-room `enroll → train-room → room-watch` loop has **not** yet run on-target — the headline remaining gap. Open refinements: `--source-format adr018v6` (drive from the Pi's own nexmon), phase-based breathing carrier, RVF/HNSW storage, and the ADR-150 frozen HF backbone the specialists would distill from.

The complete `baseline → enroll → train-room → infer` loop is now **proven in-process** on deterministic synthetic CSI (`tests/full_loop.rs`: clean baseline with zero motion flags, 8/8 anchors through the quality gate, 6 specialists trained, JSON bank round-trip, trained-bank inference 18±2 BPM positive / absent negative / foreign-baseline STALE; seed-robust). The one live runtime signal (breathing ~16–31 BPM via `room-watch`) used the *stateless* breathing head, **not** a trained bank; the clean empty-room loop has **not** yet run on-target — the remaining gap is strictly the hardware session (empty room + operator anchors). See the integration doc §7 for three behavioral findings from the full-loop test (z-band squeeze, variance-only presence, ungated hz embedding) worth fixing before that session. SOTA-intake decisions affecting this system (geometry conditioning, checkerboard alignment) are recorded in ADR-152. Open refinements: `--source-format adr018v6` (drive from the Pi's own nexmon), phase-based breathing carrier, RVF/HNSW storage, and the ADR-150 frozen HF backbone the specialists would distill from.
 
 Validation per CLAUDE.md: `cargo test --workspace --no-default-features` green; hardware verification on the ESP32-S3 (currently COM8) before any release; witness bundle regenerated if the proof surface changes.
