Close residual failures from geometric sovereignty hardening without
restoring scalar-L2 or PASSTHROUGH authority:
- Ratify CORRECTION/COMPARISON via vocab-grounded tag and multi-token
subject anchors so teaching capture and cognition intent accuracy hold.
- Keep observational wave leakage from vetoing teaching while
identity_wave_gate is off; syntactic override still rejects.
- Surface GoldTetherViolationError as fail-closed tether residual rather
than aborting lifecycle observation.
- Replace excised legacy identity-eval path with a geometry-blind baseline.
- Align sensorium corridor and lift instrument assertions with sandwich
unitary close and honest PARITY when baseline already solves.

CognitiveLifecycleEngine gains an optional GoldTetherMonitor; solve() feeds
one tether_reading per turn. Control law composed with pin SD-A: closed
certified turns update the monitor (may elevate autonomy), non-admitted /
drifted turns fail-close it (autonomy hard 0), admitted OPEN superpositions
are measured WITHOUT a state update — punishing legitimate interference
states would encode the exact defect egress refuses. Chiral orientation
observed on every reading (material flip raises, fail-closed). Reading is
disclosed on LifecycleOutcome.tether, deliberately outside outcome_id
(observer state is not cognitive content). Residual kernel was already
unified (goldtether delegates to WaveManifold.measure_unitary_residual) —
the audit's 'integrate Monitor into WaveManifold' stays rejected (layering).
49 passed (tether + lifecycle + corridor).
The single explicit, fail-closed f64→f32 down-cast at the certified lifecycle
egress. serving_cast(psi_steady, certificate, verdict) -> ServingState in
core/physics/cognitive_lifecycle.py:
- Casts ONLY a state that validates as a finite 32-vector, matches its
certificate psi_digest, and was verdict.admitted — an uncertified, refused, or
digest-mismatched state is never served.
- Precision-checks the f32 result (cast_error = max|f64-f32|, unit norm) and
fails closed on an f32 precision cliff (f32_precision_insufficient) rather than
serving a silently-degraded state.
- Keeps f64 as the source of truth: psi_steady and the psi_digest content-address
chain are untouched; ServingState carries provenance back (source_psi_digest,
certificate_id, measured cast_error) for audit. f64 stays inside
relaxation/eigendecomp — this is the one place f32 appears (ADR-0245 §2.2
mechanical sympathy).
Satisfies both ADR-0244 §2.5 and ADR-0245 §2.2 (one contract, two ADRs). Measured
on a real certified outcome: cast_error ~1.2e-8, unit_norm_f32 ~0.99999998.
Off-serving (A-04 guard: chat.runtime never imports it). ADR-0245 status map +
plan doc updated.

Cohesion directive Mandates 1+2 (ADR-0244 §2.6 / §2.8).
Mandate 1 — Rust f64 geometric_product fast-path:
- core-rs/src/lib.rs: export a geometric_product_f64 PyO3 wrapper (mirrors the
f32 one; delegates to cl41::geometric_product_f64, itself a term-for-term
mirror of the pure-Python f64 kernel — same i-major scatter order, no FMA).
- algebra/backend.py: f64 branch in geometric_product, gated on CORE_BACKEND=rust
+ core_rs present (default stays pure-Python; older builds fall through on
AttributeError). The directive's f32 gate was already built; the real gap was f64.
- Contract is BIT-IDENTICAL, not tol-matched: a 1-ULP divergence would move the
f64 wave-field residual bytes and break I-02 replay under CORE_BACKEND=rust.
Verified: test_geometric_product_f64_parity N=10000 Rust-vs-Python bit-for-bit
+ CORE_BACKEND=rust subprocess hex match (core_rs built).
- Measured M1 speedup (sixth acceptance criterion): dense f64 GP ~120x
(Rust 4.3 us/call vs Python 520 us/call) with parity holding.
Mandate 2 — eigh memoization:
- cognitive_lifecycle.py: relax_to_ground's dense-branch np.linalg.eigh routed
through _cached_eigh (functools.lru_cache, keyed on the frozen hamiltonian_id +
matrix bytes), returning frozen read-only (evals, evecs) so a cache hit can
never be mutated — every hit is bit-identical. The diagonal (propositional)
fast path is untouched.
tests: test_adr_0244_mechanical_sympathy pins cached-eigh == fresh eigh,
read-only arrays, hit-returns-identical-objects, and relaxation determinism
through the cache; D9 extended with the N=10000 bit-identity gate and its
now-stale "f64 is Python-only" pins updated.
[Verification]: D9 22 passed (incl. bit-identity N=10000, core_rs built) +
mechanical-sympathy + cognitive_lifecycle green; smoke + fast lane below.
Cohesion directive Mandates 4+5. The ADR-0243 lifecycle modules were the only
content-address sites still truncating SHA-256 to 96 bits (24 hex) and passing
default=str to json.dumps — the rest of the codebase already uses full 64-hex
digests (claim_digest, cert_id, decision_id, pressure_id, ...). The default=str
+ [:24] drift had also just replicated into Lane C (biography_wiring.py).
- cognitive_lifecycle.py: _content_id drops default=str (non-serializable payload
now fails closed with TypeError) + full 64-hex; _psi_digest full 64-hex over
canonical little-endian f64 bytes via a new _le_f64_bytes helper (coercion, not
the assert form the ADR-0244 draft used — assert is stripped under -O);
matrix_sha routed through _le_f64_bytes too.
- biography_wiring.py, self_authorship.py: same _content_id hardening. Verified
every payload is JSON-safe after the existing float()/str() wrapping, so
removing default=str changes no current digest value — only future
non-serializable inputs fail closed.
- On little-endian targets the widening is an un-truncation: the new 64-hex
digest's 24-char prefix equals the old value (pinned).
tests: test_adr_0243_cognitive_lifecycle psi_digest gold updated to full+LE; new
test_adr_0244_semantic_rigor pins full-64 length, fail-closed TypeError, LE
byte-order canonicality (native vs >f8 hash-equal), and determinism.
[Verification]: D1-affected suites 66 + miner suites 23 green; smoke + fast lane below.
Implements ADR-0243 §2 honestly per the plan's deviations ledger, correcting
the §3 sketch's three pinned defects (SD-A/B/C):
- Ingress delegates superposition to sensorium_wave_feed, normalizes once at
the owned construction boundary (D-3).
- Relaxation is the imaginary-time semigroup psi <- normalize(exp(-(H-lam0)*dt)*psi)
(D-1) with a certified, never-assumed convergence certificate (D-2): exact
ground energy, achieved Rayleigh energy, eigen-residual, spectral gap, and a
psi_digest binding the certificate to the exact state it certifies.
- Two checkable problem domains: quadratic_well (convex target-decoding) and
propositional (Cl(4,1) blade lattice = assignment lattice of <=5 atoms;
diagonal penalty Hamiltonian; entailment via UNSAT(premises & !conclusion)
scored against independent truth-table gold).
- Egress composes unit-amplitude-density + certificate-binding + versor
closure (routes, does not admit, per the dual of SD-A) + ADR-0006 energy
classes + E0/E1 crystallization policy. Cold states emit a
CrystallizationProposal (epistemic_status pinned SPECULATIVE by the type;
D-5/I-03) — never a vault write.
- Quarantined off-serving (A-04): lazy barrel export, banned in the
transitive subprocess probe and the cohesion AST suite.
Adversarial verification (finder/verifier workflow; most verify agents lost
to a session limit, every surviving finding reproduced in-tree before acting)
surfaced and this closes two real defects beyond the plan text:
- egress_gate admitted any unit state paired with any converged certificate
from an unrelated run, so CrystallizationProposal could package a foreign
psi_digest next to an unrelated certificate_id as false provenance. Fixed
by binding the certificate to its state (psi_digest) and refusing mismatches
(certificate_state_mismatch).
- A state with a spectral gap below the requested tolerance could certify
with ZERO ground-space overlap (energy window alone can't resolve it).
Certification now also requires the excited weight (E-lam0)/gap <= tol
(refusal spectral_gap_below_tolerance), and the degeneracy cluster is
capped at the acceptance window so certificates report the honest
rate-limiting gap instead of absorbing a hairline split.
38 tests (31 original + 7 hardening: certificate-binding must-reject,
gap-refusal + true-ground pair, dense-branch (eigh) refusals, iterate-collapse,
Hamiltonian/egress shape must-rejects, E2 hold route, hardcoded canonical
entailment verdicts independent of the gold function's code shape).
