From 47e7eb4e65703b186e4cbfcccd0add25b625b0fa Mon Sep 17 00:00:00 2001 From: Shay Date: Fri, 17 Jul 2026 22:51:46 -0700 Subject: [PATCH] =?UTF-8?q?feat(adr-0246):=20Opus=20audit=20+=20=C2=A73.7?= =?UTF-8?q?=20admit=20surface=20+=20serve=20wiring=20+=20=C2=A76.3=20discr?= =?UTF-8?q?imination?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
