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.
[Verification]: uv run core test --suite smoke -q => 176 passed (post-wiring);
ADR-0246 suites 80 passed; egress wiring + D4 gate surfaces 47 passed
(byte-identity); §6.1/6.2 eval 14/14; discrimination report numbers above.
See docs/audit/adr-0246-slice1-opus-audit-and-hardening.md + run log.
BOUNDED AUTONOMOUS SCAFFOLD DRAFT (Fable 5) — not a PR, not merged, no status
flip, no main push. For Opus 4.8 + Shay audit before anything proceeds toward main.
Stacked on the verified §3-primitives + §3.4/3.5-ledger stack (reuse, not re-derive;
all descend from main @ 04d67ca5).
Adds (directive steps 3-4):
+ evals/adr_0246_geometric_suite/ runnable §6.1 synthetic geometric suite
(identity, pi-inversion, 90deg-permutation, mild drift, alien tilt e14,
boost e15, near-singular Gram, malformed F) + §6.2 path/holonomy suite
(lawful sequence, small-rotation session accumulation, interleaved refuse,
pack-change hard break, raw!=lawful forensic). 14/14 cases pass.
+ tests/test_adr_0246_geometric_suite.py pins every case + explicit §6.1 pins
(pi-inversion s=-1, 90deg s=0, near-singular Gram error, malformed-F error)
+ identity_manifold.py: MalformedVersorError + _validate_versor guard on
induced_action / typed_residual_energy (§6.1 fail-closed on malformed F)
+ docs/handoff/adr-0246-slice1-scaffold-notes.md placeholder list, §5-§7
uncertainties, constraint-compliance record, explicit Opus/human TODOs
+ docs/audit/artifacts/adr-0246-slice1-scaffold-runlog.txt actual run output
Constraints honored: H_id={I} only; no soft-projection of unlawful A; path
composes lawful actions only (never raw product); no C_id corrector; chat/runtime,
flags, D4 gate wiring untouched (A-04 quarantine pinned); no discrimination report,
no ADR body, no claims language (deferred TODO: Opus/human); D4 plan not modified.
epsilon_turn/epsilon_session are UNCERTIFIED PLACEHOLDERS, never baked into a
module default (PathBudget is caller-supplied) — flagged in notes + run log.
[Verification]: uv run core test --suite smoke -q => 176 passed;
python -m evals.adr_0246_geometric_suite => 14/14 all_passed;
ADR-0246 suites + adjacent D4 identity surfaces => 114 passed (see run log).
First implementation unit of ADR-0246 Ring-1 per the preflight brief §3/§13.
Promotes the induced-action apparatus from the slice-0 eval prototype into pure,
tested geometry — the single source of truth both the future gate surface and the
§11 grounding-feasibility study will consume.
core/physics/identity_manifold.py:
+ induced_action(versor) A(F) = G^-1 · <a_k, F a_j F~>_0 (§3.1)
+ orthogonality_defect(versor) d_orth = ||A^T G A - G||_F (§3.2)
+ typed_residual_energy(versor) e4/e5/spatial_foreign/unclassified (§3.6)
+ orthogonality_defect_of_action / SPATIAL_GRADE1_INDICES / E4,E5 index pins
core/physics/identity_action.py (new, pure):
+ IdentityStabilizer (locked singleton H_id={I}, §3.3)
+ stabilizer_defect d_stab = min_H ||A - H||_G (§3.2)
G-weighted norm reduces to Frobenius at G=I (default pack)
evals/adr_0246_mismatch_diagnostic: rewired to delegate to the canonical
primitives (removes the duplicate prototype copies; drops unused import).
Scope: off-serving (algebra-only, A-04 quarantine, pinned by test); no gate,
threshold, axis, H_id, corrector, or flag change. identity_wave_gate stays
default-off. Path ledger (§3.4/3.5), gate admit surface (§3.7), and the eval
matrix + §11 feasibility study are subsequent units (brief §0a records the
sequencing). No self-Accept.
[Verification]: uv run core test --suite smoke -q => 176 passed;
tests/test_adr_0246_induced_action.py 12 passed (RED-first);
identity surfaces (mismatch-diagnostic rewired, identity_manifold, identity_gate
wave/runtime/eval, gamma_calibration) 87 passed.
Freeze the post-D4 planning baseline for the next identity ADR series:
lawful stabilizer H_id={I}, induced action A(F), d_orth/d_stab split,
lawful-only path composition with hard ledger breaks, typed residual
channels, admit-or-abstain only, and explicit non-goals (no geometric
C_id, no multi-port framework in this slice).
Implementation starts only after D4 Phase 6 (or explicit waiver). Does
not expand or interrupt the live ADR-0244 D4 arc.
[Verification]: Smoke suite passed locally (314s, 176 passed)
- Proved that analytical Clifford polar C_AB = B~A is mathematically ill-posed
for multi-grade 32-vector fields, as ~C C is not a scalar.
- Cemented _field_conjugacy_versor (SVD + Spin Gauss-Newton) as the mathematically
optimal and honest way to extract sandwich conjugators.
- Updated ADR-0241 to demote the polar claim and favor the thin wrap.
- Updated third-door-blueprint-fidelity.md to flip W3 to GREEN (honest demotion).
- Added behavioral RED test to demonstrate the multi-grade breakdown of ~C C.
Land entity-cohesion foundation for ADR-0241 mastery: public VaultStore
get_versor/get_entry ABI (drop private _versors in holographic vault),
resonant_reconstruct + phase_correlation on WaveManifold, cohesion master
plan + Phase 0/serve quarantine suite, fidelity honesty pass, and Gemini
handoff brief for ADR-0242 atlas packing + Fibonacci search.
Two-session arc where engine derives connective+object from corpus
decomposition; operator ratifies rather than authors. Distinguishes
from learning-loop (operator-authored) and directly exercises W-018
checkpoint contemplation and W-017 auto-proposal provenance path.
