Composes v2-EN's connective grammar (if/then, or, and, either) with
v3-MEM's singular-membership sentence reading over one shared
per-individual atom space, so "If Socrates is a man then Socrates is
mortal. Socrates is a man. Therefore Socrates is mortal." decides — the
exact gap ADR-0258 §6.1 reserved. Genuinely fuses the two mechanisms: a
bare universal's instantiated atom can unify (via the same closed
morphology relation) with a connective leaf's atom, deciding arguments
neither band alone could.
- generate/proof_chain/cond_member.py: new reader. A sentence is checked
for a connective token BEFORE the universal-lead check (so a stray
connective can never leak into an opaque name/class run); reuses v3-MEM's
own _parse_singular/_parse_universal verbatim (already negation-aware,
so no separate negation layer is needed, unlike v2-EN's opaque minter).
Four new shape-bands (fused/disjunctive/chain/conditional), each earning
its own SERVE license.
- chat/deduction_surface.py: new fallback tier tried strictly after v3-MEM
— pure widening, every previously-served argument stays byte-identical.
- evals/deduction_serve/practice/gold.py: 4 new synthetic template groups
(20 templates), reusing the v3-MEM case generator; intended formulas
cross-checked against the independent oracle (INV-25).
- evals/deduction_serve/v2_condmem/: 26 hand-authored real-English cases,
content-disjoint from the synthetic corpus.
- ds-mem-0024 promoted declined -> unknown (not entailed — the antecedent
is never asserted in that text; this is the first promotion in the
corpus that doesn't land on entailed).
- Ledger re-sealed to 17 bands; deduction_serve_v1 lane SHA re-pinned
(surgical single-line edit, not a blanket --update).
Verification: core test --suite deductive 160 passed (31 new reader

CORE now decides natural-English deductive arguments end-to-end:
'If it rains then the ground is wet. It rains. Therefore the ground
is wet.' -> ENTAILED, rendered over the user's own clauses. Both of
ADR-0256's documented boundary cases (multiword conditional, nested-
negation contraposition) are now decided; their lane gold updated
declined->entailed.
- generate/proof_chain/english.py (new): closed function-word grammar
over OPAQUE clause-atoms (minted ids); if/then, [either] or, and,
three negation forms (leading not / sentential / copular incl.
contractions); typed refusals; honesty caps. Soundness: positive
verdicts are substitution-closed; UNKNOWN is scoped + guarded
(quantifier-led, is-a membership, unnormalizable negation refuse
out of the opaque band).
- render_entailment_english: verdicts quoted back verbatim; UNKNOWN
phrasing explicitly scoped to the opaque reading.
- chat/deduction_surface.py: v2-EN fallback tier AFTER v1/v1b —
monotone widening, byte-identical on previously-served arguments.

Pins the arc's original goal against the ACTUAL serving spine (ChatRuntime,
the driver core chat constructs), not just the composer: a user asks a basic
logic question -> CORE decides -> an articulated, deterministic, telemetered
response comes back. Covers propositional + categorical, flag-off byte-identity
across both bands, honest reader-refusal on out-of-regime input (INV-34), and
the peripheral-systems wiring.
Peripheral systems verified (nothing to build, all automatic): deduction
turns are well-formed served turns (turn_log grows, _context.turn advances)
so ADR-0255 discovery-yield counts them; they carry grounding_source=
'deduction' on ChatResponse + TurnEvent and an observable DispatchAttempt;
they emit no discovery candidates (decided answer, not a would-have-grounded
gap) so they lift the yield denominator without inflating the numerator.
Scope-out doc (docs/research/deduction-serve-arc-completion-and-scope-outs-
2026-07-23.md) records the whole arc + everything deliberately deferred with
rationale: multi-word English reader relaxation (risky, shared reader, its
own pass), multi-step proof recap (Phase-6 core_logos), accrue_realized_
knowledge default, ADR-0246 s3.7 (blocked on research evidence not wiring),
Tier-2 (waits for field reader), Hamiltonian compiler (eval-side), and the
GroundingSource enum registration.

core chat now decides Aristotelian syllogisms end-to-end -- the marquee
'basic logical work' widening. Closes Phase 0's fork: the ONLY categorical
decider was evals/syllogism/oracle.py (the sealed independence oracle serving
must not import; INV-25). This ships a production decider.
generate/proof_chain/categorical.py lowers a categorical argument to the
propositional regime (one Boolean atom per term-membership profile) and rides
the already-verified ROBDD engine -- no new decision procedure, soundness
inherits from the flagship. Sound AND complete for the modern/Boolean reading
(Darapti + existential-import-only forms correctly INVALID), with no reliance
on a lucky domain size. Independent of the eval oracle by mechanism (ROBDD-
over-profiles vs brute-force finite-model enumeration); proven by case-for-case
agreement with it across the whole syllogism gold lane.
New: generate/proof_chain/categorical.py, render_syllogism (deterministic
valid/invalid/inconsistent templates), CATEGORICAL shape-band, arena
categorical band (4 valid forms + 2 invalid, by-construction gold cross-checked
vs the independent syllogism oracle), tests/test_categorical_decider.py (8
tests incl. the independence-by-agreement proof).
Changed: chat/deduction_surface.py (categorical branch, license-gated via a
shared _license_gate helper; propositional path byte-identical), arena
DeductionSolver dual-path in lock-step with the composer, re-sealed ledger (5
bands, categorical earns SERVE at 0.99087 wrong=0), Phase-2 lane decide()
mirrors the dual path with the 3 categorical cases reclassified to their true
valid/invalid verdicts + 1 invalid case (n 27->28), report+SHA regenerated.
Honest wrinkles: irregular plurals ('fish') decline with unknown_morphology
(a reader limit, correctly not a wrong); surfaces read in singularized terms
('all whale are animal') -- the exact ids the engine reasoned over, no cosmetic
re-pluralization that could drift from the decision.

Deduction serving stops being a bare flag and becomes an EARNED capability
governed by the ADR-0175 reliability gate over the ADR-0199 learning arena
-- the arena's second concrete instance (GSM8K math is the first) and the
reliability substrate's first non-estimation serving consumer, a concrete
dent in that zone's standing 'designed, not wired' critique.
Non-circular thesis: the ROBDD engine is sound+complete (never wrong on the
problem it's handed), so the license does NOT certify it. It certifies the
full pipeline (reader -> projector -> engine) per argument shape -- the
FALLIBLE part is the template reader, which can misparse an argument and
hand the engine the wrong problem. The arena catches that as a 'wrong' by
comparing the pipeline's committed outcome to by-construction gold.
New: generate/proof_chain/shape.py (4 exhaustive structural shape-bands, the
capability axis, shared by arena + serving), evals/deduction_serve/practice/
(the deduction arena instance: deterministic synthetic corpus, by-construction
gold independent of the reader per ADR-0199 L-2, cross-checked against the
INDEPENDENT truth-table oracle before sealing), chat/data/deduction_serve_
ledger.json (committed SHA-sealed ledger, 4 bands x 720 correct/0 wrong),
chat/deduction_serve_license.py (tamper-evident serving reader, mirrors
estimation_license.py), tests/test_deduction_serve_license.py (13 tests),
docs/adr/ADR-0256 (+ resolves the ADR-0206 numbering collision in doc form).
Changed: chat/deduction_surface.py (composer consults the license: earned
band -> authoritative Phase-1 surface; unearned/stripped ledger -> same sound
answer served DISCLOSED/hedged -- authority now rests on committed evidence,
not a boolean), core/config.py (flag docstring: enables an EARNED path),
core/cli_test.py (deductive suite runs the license test).
All four structural bands earn SERVE at reliability 0.99087 (>= theta_SERVE
0.99) with wrong=0, so Phase-1 behavior is preserved byte-for-byte; the
gate's teeth are proven by injecting an empty ledger (the same sound answer
degrades to a disclosed hedge). Did NOT reuse the ADR-0206 govern_response
bridge (its STRICT/APPROXIMATE 'widen-past-strict' semantics are the opposite
shape from deduction's always-sound answer); did NOT rewrite report.json's
stale adr field (SHA-pinned bytes, documented in ADR-0256 s2a instead).

New evals/deduction_serve/ lane scores the PRODUCTION serving decider
(the exact comprehend -> to_deductive_logic -> evaluate_entailment_with_trace
pipeline chat/deduction_surface.py runs) end-to-end from raw text --
distinct from evals/deductive_logic (bare engine vs formula strings) and
evals/comprehension/propositional_runner.py (reader fidelity vs the
independent oracle, not the production engine). This is the only lane
proving the capability core chat actually serves.
27 hand-authored cases (gold computed by independent logical reasoning,
not copied from a first engine run), 4 classes: entailed/refuted/unknown/
declined. 27/27 correct, wrong=0. Wired into core test --suite deductive
(tests/test_deduction_serve_lane.py) and SHA-pinned in
scripts/verify_lane_shas.py (deduction_serve_v1).
Honesty check during authoring: a case intended as 'entailed'
(contraposition, 'Therefore if not q then not p') actually declined --
tracing why found a genuine reader-grammar boundary (negation cannot
nest inside an if/then clause; generate/meaning_graph/reader.py's _chunk
rejects it). Reclassified to declined/out_of_band_nested_negation
(documented in contract.md) rather than forcing an artificial pass, and
added a replacement entailed case (three-hop chain) to keep coverage.
Out-of-scope finding (documented, not fixed here): running
scripts/verify_lane_shas.py --update to compute this lane's pin also
re-executed every OTHER registered lane and surfaced two pre-existing,
unrelated problems on main -- miner_loop_closure/curriculum_loop_closure/
demo_composition regenerate non-deterministic content IDs (their
committed pins don't reproduce even on a clean checkout), and public_demo
errors outright (matches the known env-timeout flake in project memory).

falling through once the vault warmed -- pack/teaching/oov are cold-start-

Weekly-audit 2026-07-22, T13 decision (2) ruling (Shay). The Shadow Coherence
Gate hard-refused open-geometry surfaces even when the surface was pack-grounded
and the openness was a geometric-coherence residual the pack never claimed to
certify — a false refusal (the warmed "What is doubt?" case:
"To doubt means to think maybe not. pack-grounded (en_core_meta_v1)." was
replaced by "I cannot certify an answer: ... contract is open (goldtether_residual).").
Fix the reading, not the question: route open-geometry-but-pack-grounded
surfaces to a hedge arm (authoritative=False), discriminated purely by grounding
provenance (structural), never by question type. The query-type classifier
bypass was rejected as a fail-open cue-table (ADR-0252 / INV-34).
- core/cognition/surface_resolution.py: the decision lives INSIDE the gate.
Predicate: pack_grounded (grounding_provenance in {pack, teaching}) AND every
open token in {versor_condition, goldtether_residual}. The ¬hazard clause is
enforced structurally by that residual allowlist — any unrecognized open token
(where a genuine safety/harm/imperative hazard lands), non-pack grounding, or a
None assessment falls through to the unchanged fail-closed refusal. New
authority tag grounded_open_hedge; hedged=True; walk/compose folds suppressed.
- core/cognition/pipeline.py: thread grounding provenance into resolve_surface
(read once at the gate seam, reused for the OOV telemetry).
- docs/adr/ADR-0254: the serving-physics decision + fail-closed argument.
- tests/test_grounded_open_hedge_arm.py: RED->GREEN unit suite + real-data
warmed-session integration.
Genuine safety/harm hazards are unaffected: they ride separate axes
(SafetyVerdict refusal, logos-morph override) that supersede this surface.

Wire observed-HE morph constraint into CognitiveTurn answer path and

Close residual answer-authority debt: typed CoherenceRefusal/ContractViolation/
FieldFailure, structured ProofTrace (atoms→operators→closure), and Shadow Gate
paths that refuse certified answers when contract_assessment is None or geometry

unitize in generate/), three field outcomes, and an articulation firewall that
blocks payload-value citation bypass and uncertified content.
Non-admissible candidates no longer enter work/derived. Only admissible

Discharges Josh's Q3 ruling: defer the q:difference capability, close the
hazard now. _pattern_b_comparative_candidates is inert by construction
(returns []), so 'how many more/fewer … than …' questions refuse end-to-end
even when every statement injects cleanly. This suite LOCKS that so a future
D.5 wiring cannot reopen the guessed-direction hole without positively
determining the more/fewer direction. Verified inert-safe by 5 direct tests.
Two shapes (PR ruling) pinned compiler-side with tests — reader direction errors
surface as refusals, never wrongs:
- Chained / ordering: a compare whose reference is neither seeded nor
already-defined at that point refuses (compare_reference_not_a_register).
Pinned explicitly with a test (story order != dependency order), not left to
fall out of existing checks.
- Inverse mis-direction: a compare that would DEFINE an already-known (seeded or
earlier-defined) register refuses (compare_redefines_register) — the reader
must bind the unknown side as the target with a fraction factor; the compiler
never overwrites a known quantity.
The 5 real compare cases still solve wrong=0. 27/27 (2 new guards + 25).

Amendments (PR #76):
1. Summation registers-driven: MultiRegisterProgram.register_order (seed order
then compare-defined order); execute sums ALL registers in that order, so a
compare-DEFINED register (no seed) is included in totals. compile validates
the answer target AFTER ops (a concrete unknown may be compare-defined) and
propagates the defined register's unit from the reference.
2. Compare record: RegisterTurn.reference; MultiRegisterRecord.source_entity
(the reference) + operand_source_digest (reference state digest), both
CONDITIONAL in the payload so affine/transfer/summation record digests are
byte-identical to before compare. Re-verification reconstructs the source
register from records alone.
Compare CREATES a quantity (not a transfer) -> exempt from the conservation pin.
fraction direction folded in (factor < 1). compare_additive is a later increment

A total-like unknown (unknown.entity is None, 'how many altogether') is no longer
refused — it compiles to a certified summation over all registers (ruling #1:
summation stays in the substrate). The distinction is the explicit typed signal
(None entity), not an inferred op-sequence pattern.
Each addition is a certified relaxation turn; the operand is the decode of a
certified register state, bound by operand_source_digest (= that state's
psi_digest convention). Deterministic re-execution reproduces the state and its
decode, so the Python layer cannot tamper with the intermediate value — the
chain-of-custody design (Shay's Q), now with no trusted-Python assumption.
operand_source_digest is added conditionally to the record payload, so
non-summation (T2a) record digests are unchanged.
Capstone: Tier-1 (26) + T2a single-entity (18) + summation (6) = full GSM8K dev
holdout 50/50, wrong=0. The reader->Hamiltonian compiler now solves the entire

Multi-entity arithmetic as a product of independent conformal lines: one
register (null point) per entity; per-register affine ops reuse Tier-1 transport;
transfer = coupled T-k/T+k on disjoint registers (exact by P1 per-line exactness).
Transactional atomicity: immutable register mapping, prepare->validate->commit —
both candidate states relaxed into locals, validated (both converged AND
conservation), then a NEW mapping only on full success. Failure anywhere = new
mapping never built, original untouched (no partial mutation, no rollback); abort
raises typed MultiRegisterError and aborts the whole program (fail-closed).
Conservation pin = hard-reject, RELATIVE (|after-before| <= rtol*max(1,|before|)):
decoded-quantity error scales with magnitude (found via gma-050 chaining to 222),
so absolute tol is wrong; relative still catches real violations (off by whole k).
Content-addressed MultiRegisterRecord chain carries entity + certificate id +
step, never a decoded value; GENESIS-linked; verify_multi_register_chain mirrors
verify_replay_chain. Tier-2a fail-closed taxonomy: total-unknown (needs summation

unknown endpoints. Off-serving (A-04).

Wires the turn-program executor into the generalized-lift instrument and
measures it against the REAL GSM8K dev holdout (evals/gsm8k_math/dev, never the
templated cases), using each problem's ground_truth_graph. Baseline is a
symbolic fold of the SAME compiled turn program: both paths consume identical
problems, the corridor relaxes each step, the baseline folds it numerically.
Honest result on the sealed 50-case dev holdout: 26 problems are Tier-1 affine
single-accumulator ingestible and solved wrong=0; the corridor matches the
symbolic fold on every one (PARITY, delta=0) — the field matches arithmetic, it
does not beat it, so this is real-holdout coverage, NOT a manufactured lift. The
24 refused (all not_single_accumulator / multi-entity) are the recorded Tier-2
frontier, never silently dropped.
Corrects the now-stale scope-limitation note ('no reader-to-Hamiltonian compiler
exists…') — the compiler exists as of this arc; the note now records real-data
Tier-1 coverage and the multi-entity frontier. wrong_zero_guard_held extended to
bind both exact-regime domains (deductive flagship + arithmetic).
10/10 pins (5 new + 5 existing instrument tests still green).

The composition frontier: multi-step arithmetic compiled from a MathProblemGraph
into an ordered turn program (one affine relation-well per step) and executed as
a chain of certified relaxation turns. The accumulator flows turn-to-turn as a
field STATE, decoded only once at the end (anti-hollow) — the substrate performs
every step and composition depth lives in the certified chain, not matrix size.
Verified: ((5+3)*2)-4=12, (10/2+7)*3=36, (100-40)/4=15, all turns
ground_state_certified.
Ring-2 correction (verified in-tree): run_residual_protocol is zero-bound /
non-mutating — stage-5 recertification refuses if the witness moved — so it
certifies a FIXED state's admissibility, not a state TRANSITION. Arithmetic turns
mutate. So the per-turn certificate is the relaxation's own RelaxationCertificate,
and the tamper-evident SEQUENCE is recorded with the Ring-2 chain-integrity
PATTERN (content-addressed TurnRecord, GENESIS-linked, verify_turn_chain mirrors
verify_replay_chain) rather than forcing mutating turns through the zero-bound
protocol. Turn records carry certificate ids + step provenance, never a decoded
value; tamper on any non-terminal record breaks the successor link.
Tier-1 (ruling #1): single-accumulator add/subtract/multiply/divide, constant
Quantity operands, positive scale. Multi-entity/transfer/rate/comparison/
fraction/partition/non-positive-scale/unit-mismatch refused and recorded, not
silently dropped. Off-serving (A-04).
15/15 pins green.

Closes the deduction leg: propositional formula strings (as emitted by
meaning_graph.to_deductive_logic, or any logic_canonical-parseable syntax) →
corridor CNF PropositionalProblem + query Clause, consumable by
propositional_entails.
Structural, not truth-table (spike §4.1): reuses the production ROBDD parser
(generate.logic_canonical — never re-implemented) for the AST, then the standard
sound rewrite — eliminate iff/implies, NNF, distribute OR over AND — with
constant folding, tautological-clause elimination, and a clause budget. The
converter never enumerates assignments and never decides entailment; that stays
the corridor's job.
Soundness proved against the ROBDD oracle: for a 14-formula panel, the compiled
CNF rendered back to a formula has the same canonicalize() identity as the
source. End-to-end entailment through propositional_entails agrees with the
ROBDD gold (evaluate_entailment) wrong=0 on consistent premises; ex-falso
handled per the corridor's own contract (entailed + satisfiable_premises=False,
where the ROBDD path returns REFUSED for inconsistent premises).
Fail-closed: conjunctive/constant queries, formulas reducing to false, and CNF
budget refuse with typed CnfCompileError; >5 atoms surfaces the corridor's
HamiltonianCompileError(atom_count_out_of_range); out-of-regime propagates
LogicRegimeError. Off-serving (A-04), import-guard pinned.
32/32 pins green.

Compiles output = scale*input + offset (Tier-1: scale > 0) into a quadratic-well
constraint Hamiltonian, reusing the ratified compile_quadratic_well +
HamiltonianCompileError contracts.
Anti-hollow (spike §4.1): the compiler never evaluates scale*input+offset in
Python — it embeds the input (P1) and applies the relation's structure as
versor operators (dilator for scale, translator for offset), so the substrate's
geometric product performs the arithmetic. The returned well is a bare
projector carrying no answer and no coefficients (metadata = {curvature,
target_digest} only); relaxation + projective readback recover the output.
Verified end-to-end: multiply/add/subtract/divide/negative-input all decode
exactly; ablation confirms the start decodes to the input and only the relaxed
state to the answer.
Fail-closed on non-positive scale (outside positive-dilation Tier-1) and
non-finite coefficients. Golden-bytes canary pins the compiled matrix.
Serve-quarantined (A-04). Single-relation primitive; state-chaining is P4.
21/21 pins green.
[Verification]: uv run python -m pytest tests/test_adr_0249_relation_compiler.py -q
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).
1) chiral_conservation_precondition composed into integrate_validated_biography
(ADR-0241 §2.4C): sgn(Q_top) latch over the RAW trajectory before versor
validation + blade post-check; provenance schema v2 carries the chiral
proof. Honesty theorem pinned: I5 is central in odd Cl(4,1) so closed
versors have Q = 0 exactly — vacuous by theorem on admissible
trajectories (same disclosed-inertness contract as the GoldTether chiral
wiring), while LIVE against raw non-versor mirror flips (refusal pinned).
2) First real caller: evals/analogical_transfer/biography_session.py — runs
the ADR-0240 harness, recomputes the lived trajectory (recovered transfer
versors of CORRECT cases; reconstruction-over-storage), integrates on
PASS. I-01 reboot-invariance pinned BIT-IDENTICAL across runs.
3) biography.py trajectory digest now explicit '<f8' LE bytes (ADR-0245
§2.3); byte-identical on LE targets, platform-independent everywhere.
31 passed across wiring/session/holonomy/readback suites.
Egress route readback_eligible now flows into geometric token selection
(resonance = <psi psi~_T>_0 via the I-04 phase correlation; cga_inner is
the un-reversed grade-0 product and is wrong for versor states — pinned in
tests) plus the hearing-ourselves-think round-trip: articulated tokens are
re-ingested through the same sensorium boundary and phase-locked agreement
is measured with the same metric. Fail-closed typed ReadbackRefusal when no
token resonates (decoding, not generating — no fallback strings). Vocab
access is structural (VocabLike) to avoid a core.physics->vocab cycle; the
real VocabManifold satisfies it (proven in tests). 10 new pins, lifecycle
suite untouched (48 passed).
Rings 2 and 3 of the ADR-0246 preflight §9, built exactly as the brief bounds
them. ADR-0247 + ADR-0248 both **Proposed** — no self-Accept.
Ring 2 (core/ports/residual_protocol.py — ADR-0247):
the 7-stage shared control grammar: witness -> typed residual decomposition
-> permitted operator selection -> bounded operation or abstention ->
re-certification -> action decision -> append-only replay record.
Port-agnostic (no registry, no unified scheduler — §7 non-goal #2 honored);
v1 operators are ZERO-BOUND only (nonzero fails closed — no-silent-correction
doctrine); unaccounted residual fails closed; re-certification RAISES on
witness drift during a zero-bound pass; replay chain is append-only,
full-SHA-256 content-addressed, tamper-evident (verify_replay_chain).
NOTE: named core/ports/ because core/protocol/ is the existing CTP v0 wire
format (collision checked before naming).
Ring 2 adapters (core/ports/adapters.py): IdentityPort (ADR-0246 grade-1
geometry; typed channels travel IN the witness so decompose is a pure
re-shaping, no hidden state; admit = evaluate_admission, single source of
truth) + PrecisionPort (ADR-0244 §2.5 cast transport; ServingState subjects)
— two genuinely non-identical native geometries + a synthetic third port
proving grammar agnosticism.
Ring 3 (core/ports/integrity_handoff.py — ADR-0248):
the coordination seam ('Integrity coordinates handoffs; it does not replace
content-bearing cognition'): fuses Ring-2 port decisions + existing
EpistemicState/NormativeClearance into content-free proceed/hedge/abstain
(conjunctive, strongest-restriction-wins; fail-closed on missing/invalid
evidence; binds replay-chain tip digest; handoff itself content-addressed).
Weak epistemic standing hedges (mirrors hedge doctrine) — only integrity
violations silence a turn. OBSERVE-ONLY: no serve consumer yet; that is a
future flag-gated unit. Remaining Ring-3 programme honestly listed open
(world-model, governed-learning consumption, discourse widening).
Both pure/deterministic/off-serving (A-04 pinned); brief §0a/§9 updated.

Opus 4.8 audit of Fable's slice-1 scaffold + authorized hardening (Step 2).
Stacked on feat/adr-0246-slice1-scaffold. Not a PR, not merged, no status flip.
AUDIT (Step 1) — VERDICT PASS. Re-derived A(F)/d_orth/d_stab/typed channels from
§3.1/3.2/3.6 independently: BIT-EXACT vs impl (0.00e+00). Confirmed in code (not
just comments): H_id={I} locked (singleton hardcoded, no enlargement path); path
composes lawful only, refused=break marker, never raw, never soft-I; no §7 scope
creep; serve byte-identity. Finding F1 (doc, not bug): composition uses the raw
CERTIFIED action (required for §6.2 accumulation, else A_path≡I detects nothing) —
now documented for ADR ratification.
HARDENING (Step 2):
§3.7 pure surface (identity_action.py): AdmissionPolicy (calibrated flag),
evaluate_admission (admit-or-abstain, no corrector); CERTIFIED_GAMMA_ID pinned
== identity._WAVE_LEAKAGE_BOUND; all other bounds UNCERTIFIED placeholders.
§3.7 SERVE WIRING (Steps 2.1/2.2): new default-off flag identity_action_surface
(config); threaded chat/runtime -> check -> _wave_field_score; refusal folds
into flagged -> existing would_violate/conjugate_correct abstains; IdentityScore
gains action_surface_active/d_orth/d_stab (legacy defaults). Flag-off is
byte-identical (D4 gate surfaces green unchanged; smoke 176 post-wiring).
§6.3 DISCRIMINATION REPORT (evals/adr_0246_discrimination) — HONEST numbers:
benign pass 0.00, false refusal 1.00, adversarial detect 1.00, control pass
1.00; d_stab AUC 0.375 (95% CI [0.15,0.62]) — BELOW chance. Benign cognition
sits ~18x farther from the frame (mean d_stab 27.8) than the attacks (1.55).
The gate refuses everything and does NOT discriminate; must stay off; usable
separation needs the §11 grounding work, not threshold tuning. Claims language
enforced: 'lawfulness relative to the declared frozen frame', NOT 'semantic
inalienability'.
Ledger raw-sneak hardening test (Step 2.3): mixed lawful/refused sequence must
equal the lawful sub-product, fails if raw sneaks into A_path_lawful.
Handoff to Sonnet: §4.1 per-turn record, path-ledger serve integration, ADR-0246
body + acceptance packet (Proposed, no self-Accept), §11 grounding-feasibility.
