fix(adr): resolve duplicate ADR numbers + close ADR-080 security + ADR-154 M1 signal backlog (#1051)
* fix(signal): circular phase variance for ghost-tap guard (ADR-154 §7.4 #1)

`phase_variance` computed a LINEAR sample variance over phase angles that
wrap at ±π, so a tightly-clustered set straddling the branch cut reported
spuriously HIGH dispersion — false-tripping the `> TAU` ghost-tap guard on
real, tightly-clustered CIR taps.

Replace with Mardia's circular variance V = 1 − R̄, bounded [0,1] and
invariant to where the cluster sits on the circle. Re-derive the guard
against the bounded metric via a named const
`GHOST_TAP_CIRCULAR_VARIANCE_MAX` (the old TAU-scaled threshold is
meaningless on [0,1]).

Grade: metric fix MEASURED; threshold value DATA-GATED — a clean single-path
ramp also sweeps the circle, so V alone cannot separate clean from
unsanitized without labelled frames. Conservative default (0.99) errs toward
never false-rejecting, strictly more permissive at the wrap boundary than the
buggy linear guard.

Fails-on-old test: `phase_variance_circular_not_fooled_by_branch_cut` —
inlines the old linear variance to show it exceeds TAU on wrap-straddling
phases while circular V≈0 and the guard no longer trips. Plus
`phase_variance_circular_is_bounded_and_extremal` (V∈[0,1], V≈0 identical,
V≈1 uniform).

* fix(signal): pin Welford n=0/n=1 finiteness guard (ADR-154 §7.4 #10)

The shared `WelfordStats` (field_model.rs, used by longitudinal.rs and others)
relies on `count < 2` guards in `variance`/`sample_variance`/`std_dev`/
`z_score` to stay finite at the boundaries. The guards existed but the n=0
boundary was UNTESTED — exactly the §4 divide-by-(n−1) family the ADR groups
this with.

Add `welford_finite_at_n0_and_n1` asserting every statistic is finite and
returns the documented sentinel (0.0) at n=0 and n=1, plus load-bearing doc
comments on the two guards.

Fails-on-old proof: with the `sample_variance` guard removed, the test FAILS
with "attempt to subtract with overflow" at the `(self.count - 1)` underflow
(0usize − 1); `variance` would similarly yield 0.0/0.0 = NaN. The guard is
restored; the test pins it so a future regression is caught.

Grade: MEASURED (boundary finiteness is asserted; the guard is the §4-family
fix made testable).

* refactor(signal): de-magic adversarial thresholds + boundary tests (ADR-154 §7.4 #13)

Lift the bare numeric literals buried in `check`/`check_consistency` into
named, documented module consts (FIELD_MODEL_GINI_VIOLATION=0.8,
ENERGY_RATIO_HIGH_VIOLATION=2.0, ENERGY_RATIO_LOW_VIOLATION=0.1,
CONSISTENCY_ACTIVE_FRACTION_OF_MEAN=0.1, SCORE_W_* weights). VALUES UNCHANGED —
each const equals the original literal; only names + pinning tests are new.

Grade: DATA-GATED. The operating values stay empirical (defensible values need
labelled spoofed/clean CSI — Wi-Spoof, §6.2/§7.3). The de-magicking +
characterization tests are MEASURED: `tuning_consts_unchanged_from_literals`,
`energy_ratio_high_boundary`, `energy_ratio_low_boundary`,
`field_model_gini_boundary`, `consistency_active_fraction_boundary` pin the
decision boundaries at/just-below/just-above each threshold, so a future
data-driven retune is a visible, tested change.

Fails-on-change proof: bumping ENERGY_RATIO_HIGH_VIOLATION 2.0→3.0 makes
`energy_ratio_high_boundary` FAIL (restored). Operating values explicitly
NOT changed.

* refactor(signal): de-magic coherence drift/gate thresholds (ADR-154 §7.4 #9)

Lift the bare detection literals in `coherence.rs::classify_drift`
(DRIFT_STABLE_SCORE=0.85, DRIFT_STEP_CHANGE_MAX_STALE=10) and the
`coherence_gate.rs` Default impl (DEFAULT_ACCEPT_THRESHOLD=0.85,
DEFAULT_REJECT_THRESHOLD=0.5, DEFAULT_MAX_STALE_FRAMES=200,
DEFAULT_PREDICT_ONLY_NOISE=3.0) into named, documented consts. VALUES
UNCHANGED. The gate already exposed these via GatePolicyConfig (config seam);
this names + pins the defaults.

Grade: DATA-GATED. Operating values stay empirical (defensible Z-score
thresholds need labelled stable/drifting coherence traces). De-magicking +
boundary tests are MEASURED: `classify_drift_stable_score_boundary`,
`classify_drift_stale_count_boundary` pin the at/just-below/just-above
decisions; `drift_consts_unchanged_from_literals` /
`gate_default_consts_unchanged_from_literals` pin the values. Operating values
explicitly NOT changed.

* docs(adr-154): mark §7.4 P1 backlog cleared — Milestone-1 (#1,#10 RESOLVED; #9,#13 DATA-GATED)

Update ADR-154 §7.4 backlog rows #1, #9, #10, #13 with commit refs + grades,
the §7.4 intro count (four P1 items cleared, ~41 P2/P3 remain), the
Horizon-ledger one-liner (Milestone-1 DONE), and the §8 honest-limits #1 line
(metric now correct; threshold still DATA-GATED). Add CHANGELOG [Unreleased]
entry.

Grades: #1 RESOLVED (MEASURED metric / DATA-GATED threshold), #10 RESOLVED
(MEASURED), #9 & #13 RESOLVED-PARTIAL (DATA-GATED — de-magicked + boundary
tested, operating values unchanged).

Validation: cargo test --workspace --no-default-features → 2057 passed, 0
failed; wifi-densepose-signal lib → 442 passed (no-default + --features cir);
python archive/v1/data/proof/verify.py → VERDICT: PASS, hash f8e76f21…46f7a
UNCHANGED (CIR ghost-tap guard is not on the deterministic proof path).

* fix(sensing-server): stop leaking internal errors in HTTP responses (ADR-080 #2)

Six handlers in `main.rs` serialized the internal error `Display` straight
into the JSON response body, leaking server internals to any client (ADR-080
finding #2, CWE-209; reframed onto the Rust boundary by ADR-164 G11):

  - edge_registry_endpoint: a panicked spawn_blocking `JoinError`
    ("task … panicked") in a 500, and the raw upstream error in a 503
  - delete_model / delete_recording / start_recording: std::io::Error
    strings carrying OS detail / filesystem paths
  - calibration_start / calibration_stop: the FieldModel error chain

New `error_response` module: `internal_error` / `internal_error_json` /
`upstream_unavailable` log the full detail server-side only (tagged with a
correlation id) and return a generic body
(`{"error":"internal_error","correlation_id":…}`) — no `panicked`, no file
paths, no Debug chain. The correlation id lets an operator join a client
report to the exact server log line without ever shipping the detail.

Pinned by 5 error_response tests, incl. a leak-substring guard
(internal_error_body_does_not_leak_detail) verified to FAIL on the reverted
old body (returns the panic message / path / "os error"). The HOMECORE sweep
(ADR-161) covered homecore-server, not this crate.

* test(sensing-server): pin XFF-immunity + no-query-token (ADR-080 #1, #3)

Findings #1 (XFF-spoofing bypass) and #3 (JWT-in-URL, CWE-598) were logged
against the Python v1 API but are VERIFIED ABSENT on the current Rust
sensing-server, so they get regression tests rather than redundant fixes:

  - #1 XFF: there is no IP-based rate-limiter or IP-allowlist to bypass, and
    neither security middleware reads a forwarded header. Added
    bearer_auth::xff_header_never_affects_auth_decision (spoofed
    X-Forwarded-For never flips a 401<->200 decision) and
    host_validation::forwarded_headers_never_bypass_host_allowlist (spoofed
    X-Forwarded-Host: localhost never lets Host: evil.com past the allowlist).

  - #3 JWT-in-URL: require_bearer reads the token only from the Authorization
    header; WS handlers take no query token; the sole Query extractor
    (EdgeRegistryParams) is a non-secret refresh flag. Added
    bearer_auth::query_string_token_is_never_accepted — ?token= / ?access_token=
    in the URL never authenticates (stays 401) while the header path still 200s.
    Verified to FAIL when a query-token path is injected into require_bearer.

* docs(adr-080): mark P0 security findings #1-#3 RESOLVED; close ADR-164 G11

- ADR-080: Status note + per-finding closure (#1 XFF and #3 JWT-in-URL
  verified absent + regression-pinned; #2 leaked errors fixed via the
  error_response module). Records the v1-vs-Rust boundary distinction
  explicitly: v1 paths remain archived; this closure governs the shipped
  Rust sensing-server.
- ADR-164: Gap Register G11 and the Open/Gated Backlog entry marked
  RESOLVED with the fix + branch reference.
- CHANGELOG: [Unreleased] -> ### Security entry covering all three findings.

* docs(adr): renumber 6 displaced ADRs to resolve duplicate-number collisions (ADR-164 G1)

Resolves the 5 duplicate ADR numbers (6 displaced files) flagged by ADR-164
Gap Register item G1. Canonical keeper per number = first file committed at
that number (date tie-broken by inbound cross-reference count / parent-appendix
relationship). Displaced files renumbered to the next free numbers (166-171):

  050 keeps provisioning-tool-enhancements (5 refs vs 1)
    -> ADR-166-quality-engineering-security-hardening
  052 keeps tauri-desktop-frontend (parent ADR)
    -> ADR-167-ddd-bounded-contexts (its appendix)
  147 keeps nvidia-cosmos/OccWorld (the actual ADR, has Status header)
    -> ADR-168-benchmark-proof (proof companion, no Status)
    -> ADR-169-adam-mode-light-theme (was untracked)
  148 keeps drone-swarm-control-system (committed #862)
    -> ADR-170-yoga-mode-pose-system (was untracked)
  149 keeps public-community-leaderboard-huggingface (committed 16:47 vs 17:38)
    -> ADR-171-swarm-benchmarking-evaluation-methodology

Updates in-file `# ADR-NNN` headers and intra-file self-references (yoga-modes

* docs(adr): repoint inbound cross-references to renumbered ADRs (166-171)

Follow-up to the ADR renumbering (ADR-164 G1). Updates every inbound reference
that pointed at a displaced ADR, disambiguating shared numbers by title/slug so
only references to the DISPLACED topic move and keeper references stay put.

ADR-168 (was 147 benchmark-proof): README, CHANGELOG, user-guide,
  proof-of-capabilities, research docs 00/03 — all path/label refs updated.
ADR-169 (was 147 adam-mode) / ADR-170 (was 148 yoga-mode): docs/adr/README index.
ADR-171 (was 149 swarm-benchmarking): all ruview-swarm eval code+docs
  (Cargo.toml, evals/, eval_swarm.rs, metrics/mod/report/runner.rs), research
  doc 03 (every §-ref matched ADR-171 sections, not AetherArena), 00-system-review,
  series README, CHANGELOG, and ADR-148's forward/"open issues" pointers.
ADR-166 (was 050 quality-engineering / security-hardening): disambiguated from the
  ADR-050 provisioning KEEPER by topic. The HMAC/secure_tdm, directory-traversal,
  bind-address, and OTA-PSK-auth references in code comments
  (wifi-densepose-hardware Cargo.toml + secure_tdm.rs, sensing-server main.rs) and
  in ADR-052-tauri / ADR-167 all describe the security-hardening ADR -> ADR-166.
ADR-167 (was 052 ddd-appendix): inbound appendix references.

Index/registry updates: docs/adr/README.md, gap-analysis/census.md (rows +
header count), gap-analysis/lens-findings.md (collision table marked RESOLVED),
and ADR-164 Gap Register G1 marked RESOLVED with the full renumber map.

Keeper references deliberately untouched: all ADR-147 OccWorld code, all ADR-148
drone-swarm code/docs, all ADR-149 AetherArena refs (incl. ADR-150's SSL/resampling
refs, which ADR-150 explicitly binds to the AetherArena benchmark), ADR-050
provisioning refs, ADR-052 tauri refs. The frozen GitHub blob URLs in
docs/adr/.issue-177-body.md (pinned to an old branch) are left as historical.

Comment-only code edits; no behavior change. wifi-densepose-hardware compiles
clean; the sensing-server build's sole blocker is the pre-existing upstream
midstreamer-temporal-compare@0.2.1 registry crate, unrelated to these edits.

Beyond-SOTA engine/signal/train improvements: mesh partition guard, FFT CIR solver, canonical frame decoder, falsifiable occupancy benchmark, governed streaming, adapter provenance (#1018)
* docs(research): add RuView beyond-SOTA system review (00)

First document of the beyond-SOTA research series: capability audit of
the current RuView engine with role-to-crate maturity matrix, ruvsense
module inventory, gap analysis, and risk register.

https://claude.ai/code/session_01MjBucx95K4BuUxZi8NWwRH

* docs(research): add beyond-SOTA series index with validation results; changelog

README index ties the 5 research docs together with the session's
measured validation evidence: 2,797 workspace tests / 0 failed, Python
proof PASS (bit-exact), and paired pre/post criterion CIR benchmarks.

https://claude.ai/code/session_01MjBucx95K4BuUxZi8NWwRH

* perf(signal): precompute CIR warm-start system; hoist tomography solver allocs

Exact, determinism-safe optimizations (bit-identical float results):

- cir.rs: diag(PhiH Phi)+lambda*I and its CSR matrix depend only on Phi
  and lambda (fixed at CirEstimator::new) but were rebuilt every frame
  (O(K*G) pass + CSR allocation). Now built once in new() via
  build_warm_start_system; summation order unchanged.
- tomography.rs: ISTA gradient buffer hoisted out of the 100-iteration
  loop (fill(0.0) reset) and the Frobenius Lipschitz bound moved from
  per-reconstruct to construction.

Verified: signal 456 tests green; engine 11/11 green including
cycle_is_deterministic and witness-stability tests. Criterion paired
pre/post: cir_estimate/he40 -3.9% (p<0.01), multiband -1.2/-1.4%.

* fix(worldgraph): bound SemanticState growth with deterministic retention

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.

* feat(sensing-server): route live frames through the governed StreamingEngine

Closes the live-trust-path gap (ADR-136 section 8, beyond-SOTA system review):
the running server fused live CSI with the bare MultistaticFuser, while the
privacy/provenance/witness control plane (ADR-135..146) only ever ran on
synthetic in-test frames. The privacy control plane was therefore bypassable
on the real path.

New engine_bridge module drives StreamingEngine::process_cycle from the
server's live NodeState map, reusing the existing NodeState -> MultiBandCsiFrame
conversion. It lazily wires each contributing node as a WorldGraph sensor
(idempotent), bounds belief growth via the retention cap, and forwards explicit
timestamps/calibration ids so the path stays deterministic and replayable.

Wired additively into both live ESP32/WiFi fusion sites in main.rs via a
split-borrow off the write guard, so person-count behavior is unchanged; the
latest BLAKE3 witness is stored on AppState. Every published belief now carries
evidence + model + calibration + privacy decision and a deterministic witness.

Adds wifi-densepose-engine/-worldgraph/-bfld/-geo deps. 6 new bridge tests
(witnessed belief with full provenance, cross-run determinism, idempotent node
registration, retention bound, privacy-mode propagation). sensing-server suite
430+128 green; workspace gate 2,904 passed / 0 failed.

* feat(train): falsifiable occupancy benchmark with anti-overfitting gate

Makes the presence/person-count "beyond SOTA" claim falsifiable in code
instead of aspirational (the unfalsifiability gap from the beyond-SOTA system
review). occupancy_bench grades predictions vs ground truth and gates a SOTA
claim behind one claim_allowed invariant requiring ALL of:

- DataProvenance::Measured — synthetic/mock data is scorable for regression
  but never claimable (anti-mock-contamination; the CLAUDE.md Kconfig-bug
  lesson made structural).
- A leak-free EvalSplit — validate() refuses any split where a subject OR
  environment id appears in both train and test (subject leakage /
  per-environment overfitting).
- n_test >= min_test_samples (small-N guard).
- Presence F1 whose bootstrap-CI lower bound (deterministic seeded splitmix64)
  clears the threshold — not the point estimate.
- Count MAE within threshold.

The claim string is unreadable except through the gate (NO_CLAIM otherwise),
same discipline as the ruview-gamma acceptance gate. What remains is data, not
method: a frozen, SHA-pinned, subject/environment-disjoint measured replay set
turns the claim into a passing/failing test.

Lives in wifi-densepose-train (the eval bounded context, alongside ablation/
eval/metrics). 10 tests cover each refusal path; warning-clean under the
crate's missing_docs lint. Workspace gate 2,914 passed / 0 failed. Doc 03
updated.

* feat(engine): per-room adapter provenance + drift-to-recalibration advisor

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.

Engine 15 tests, bridge 7 tests. Workspace gate: 2,918 passed / 0 failed.

* fix(mat): gate api module behind its feature — standalone no-default-features builds

pub mod api was unconditional while its only dependency, serde, is optional
behind the 'api' feature, so any build without default features failed with
101 unresolved-serde errors (masked in --workspace runs by feature
unification). The api module and its create_router/AppState re-export are now
cfg(feature = "api")-gated with docsrs annotations.

All combos compile: bare --no-default-features (was 101 errors, now 0),
--no-default-features --features api, and full default (177 tests pass).
Workspace gate: 2,918 passed / 0 failed.

https://claude.ai/code/session_01MjBucx95K4BuUxZi8NWwRH

* perf(signal): opt-in FFT operator for the CIR ISTA solver (8-14x measured)

Phi is a sub-DFT, so each ISTA mat-vec can run as one length-G FFT
(O(G log G)) instead of a dense O(K*G) product — the dominant-latency-hazard
finding from the beyond-SOTA optimization roadmap.

New CirConfig::fft_operator, default FALSE: the dense path stays the
bit-exact witness default. The FFT evaluates the same sums in a different
order, so enabling it shifts float results in the last bits and requires
regenerating any pinned witness — strictly opt-in per deployment.

FftOperator (rustfft, planned once at CirEstimator::new, scratch buffers
reused across the ISTA loop) dispatches inside ista_solve:
  Phi x   = scale * forward-FFT(x) sampled at bins (k_idx mod G)
  Phi^H v = scale * unnormalised inverse-FFT of v scattered into those bins
Warm-start and Lipschitz estimation stay dense at construction.

Measured (criterion, same run, same machine):
  ht20: 2.22 ms -> 265 us  (8.4x)
  ht40: 10.26 ms -> 717 us (14.3x)
The real HE40 grid (K=484, G=1452) scales further per the O(K*G)/O(G log G)
ratio.

3 new tests: FFT<->dense matvec equivalence to float tolerance on ht20 and
he40 grids; end-to-end dominant-tap agreement on a single-path frame; all
default configs keep FFT off. New cir_estimate_fft bench group.

Workspace gate: 2,921 passed / 0 failed (default path bit-exact, witnesses
unchanged).

* feat(core): canonical frame decoder — capture-to-claim replay (ADR-136)

The encode half of the ADR-136 frame contract existed (ComplexSample,
to_canonical_bytes, witness_hash) but there was no decoder: a captured
canonical frame could be witnessed but never reconstructed, blocking
replay-from-capture.

CsiFrame::from_canonical_bytes is the exact inverse: same id, metadata,
complex payload, and witness hash (tested as the round-trip law AC7 — the
replayed frame re-encodes byte-identically). Amplitude/phase are recomputed
from the payload (projections, not independent state). Every malformed-input
class fails closed (AC8): header truncation -> Truncated, payload truncation
-> PayloadMismatch, unknown discriminants, non-UTF-8 device id, trailing
bytes. Nil calibration uuid decodes as None per the documented encoding.

Core: 36 tests pass. Workspace gate: 2,937 passed / 0 failed.

https://claude.ai/code/session_01MjBucx95K4BuUxZi8NWwRH

* feat(engine): dynamic min-cut mesh partition guard (ruvector-mincut)

Maintains an exact min-cut over the live mesh coupling graph — nodes are
sensing nodes, coupling is the product of fusion attention weights — and
surfaces per cycle, as TrustedOutput::mesh:

- cut value: the global "how close is the array to partitioning" number,
  a structural measure per-node heuristics miss;
- weak side: which specific nodes would split off (failure/jamming triage,
  feeds ADR-032 posture);
- at-risk flag: counts as a structural event for the drift->recalibration
  advisor (alongside ADR-142 change-points).

Degenerate cases fail toward risk: a node with zero coupling is reported as
already partitioned (cut 0, that node as the weak side).

Measured cost policy (criterion, 12-node mesh — the honest part):
- weights quantized (1/64) + change-gated: steady-state cycles do ZERO graph
  work and reuse the cached cut (~7.3 us, ~23x cheaper than building);
- on any real change a full exact rebuild (~171 us) is used, because ONE
  DynamicMinCut delete+insert measured ~240 us — the subpolynomial machinery
  amortizes on much larger graphs, so rebuild-on-change is the measured
  optimum at mesh scale (one-edge case -28% after switching policy);
- full process_cycle with the guard: ~33 us for 4 nodes vs the 50 ms budget.

9 mesh_guard tests (weak-node detection, steady-state zero updates,
sub-quantum gating, join/drop rebuild, determinism, disconnection) + an
engine-level wiring test (down-weighted node -> weak side -> recalibration).
Engine 24 tests; workspace gate 2,946 passed / 0 failed.

* feat(engine): mesh partition risk demotes privacy + enters the witness (ADR-032)

Completes the mesh-guard integration: its at_risk signal was advisory-only
(fed the recalibration advisor). It now also contributes to the ADR-141
privacy demotion alongside fusion- and array-level contradictions — a mesh
close to partitioning makes the fused belief less trustworthy, so the cycle
emits at a more restricted class (monotonic; information only removed).

Because effective_class feeds the BLAKE3 witness, a fragmenting array now
shifts the witness: partition risk is auditable, not just logged. The mesh
computation moved ahead of the demotion step in process_cycle; mesh_guard_mut
exposes risk-threshold tuning.

Test: a forced-risk 3-node cycle demotes PrivateHome Anonymous->Restricted
and shifts the witness vs a clean baseline. Engine 25 tests; workspace gate
2,947 passed / 0 failed.

https://claude.ai/code/session_01MjBucx95K4BuUxZi8NWwRH

* fix: public-PR review findings — privacy-path honesty, gate holes, mesh-guard cliff

- sensing-server: engine errors logged+counted (no silent swallow), trust
  state exposed via status surface, privacy-demotion claims aligned with
  the actual parallel-audit-path behavior
- occupancy_bench: vacuous-F1 hole closed (degenerate test sets fail with
  their own criterion); CI-lower-bound test made probative
- mesh_guard: quantization scaled to observed coupling range — >=65-node
  balanced meshes no longer permanently at_risk (regression test)
- engine: both wiring tests made probative (same-topology witness compare,
  deterministic risk-crossing fixture)
- mat: axum/tokio optional behind api; real serde feature (api enables it)
- core: canonical decoder strict (non-zero reserved bytes and nil UUID
