From 4941cf188ee317c4f11b211315b75bb13354f503 Mon Sep 17 00:00:00 2001 From: Shay Date: Fri, 17 Jul 2026 21:36:57 -0700 Subject: [PATCH 1/5] =?UTF-8?q?feat(adr-0246):=20=C2=A73=20induced-action?= =?UTF-8?q?=20primitives=20(pure,=20off-serving)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 · _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.

I + implemented `‖M‖_G = ‖G^{1/2} M G^{-1/2}‖_F` (metric-consistent; reduces exactly + to Frobenius at `G=I`, which is the only shipped pack). **Needs review/ratification.** +2. **§3.6 `spatial_foreign` channel.** For the default pack (support = e1/e2/e3) it + is structurally ~0 (projection removes in-span components). Implemented generally + (residual energy on grade-1 spatial slots outside the axis support) but it cannot + fire until a non-default pack exists. Untested against a real non-default pack. +3. **§4.1 `IdentityActionRecord` full telemetry** (per-turn `field_digest`, + `record_digest`, gate/policy versions, admitted/refusal_reason) is **not built**; + only the §4.2 `IdentityPathLedger` (with `ledger_digest`, `chain_id`) is. The + per-turn record belongs to the gate-surface/telemetry unit (§3.7), out of scope + here. `advance_identity_path` returns a lightweight per-turn dict, not the full record. +4. **§6.1 "Malformed F → never silent legacy when wave field was supplied."** The + "silent legacy" clause is about the D4 gate's dual-mode fallback in + `identity.py` (untouched here, owned by D4). This scaffold adds a fail-closed + `MalformedVersorError` at the *pure primitive* boundary (`induced_action` / + `typed_residual_energy`). Whether the gate should route malformed-F to this same + typed error is a gate-wiring decision, deferred. +5. **Path budget semantics under a hard break.** I treated a scope change as: start + a fresh chain, and the triggering turn is turn 1 of the new chain (its own action + composes into the fresh `I`). The brief (§3.5) specifies a new `chain_id` and + that the old path is not continued, but does not pin whether the boundary turn + belongs to the old or new chain. Chose new-chain. **Confirm.** + +--- + +## 5.

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.

Slice 0 and the §6.3 discrimination report both showed +that NO fixed spatial 3-frame (declared or random) is dynamically preserved by +benign cognition. This study asks the prior, narrower, and answerable question: + + Does *any* held-out-stable, low-dimensional structure exist in what the + live versor's generator actually does — independent of which frame we + declare — and if so, does it discriminate benign traffic from adversarial + geometric attacks? + +This is explicitly a FEASIBILITY STUDY, not an implementation. Per the Opus +handoff (§4c item 4) it is "the only path to a gate that discriminates"; the +brief's own instruction (research-question authority, not this module) is that +only a positive, held-out-stable, safety-relevant finding here would justify +drafting a revised ADR-0246 implementation contract. This module does not +draft one — it reports what the data shows, honestly, including a null result. + +**Method (fixed cohort splits, no resampling of the same pool):** + + * TRAIN — benign versors from ``LIVE_PROBE_SEQUENCE`` (D4 Phase 3 / slice-0's + pinned probe set), n≈13. + * HELD-OUT — versors from ``PARAPHRASE_PROBE_SEQUENCE`` (independently worded, + same semantic register), n≈12. A genuine generalization test: any structure + found on TRAIN must ALSO appear on HELD-OUT, not merely be re-discovered by + refitting the same pool. + * ADVERSARIAL — the existing crafted geometric-attack cohort (tilts, boosts, + inversions, permutations), n=8, reused from ``evals.adr_0246_discrimination``. + +**Generator proxy (no scipy; numpy-only per the routing instruction).** Rather +than a matrix logarithm, this study uses the versor's own GRADE-2 (bivector) +coefficient vector (Cl(4,1) indices 6..15, 10 dims) as the generator proxy: for +a versor close to a simple exponential ``F = exp(B/2)``, the bivector block of +``F`` is proportional to ``B`` to leading order, and it is EXACT for the single- +plane simple rotors/boosts used throughout D4/ADR-0246 (this is the same +quantity ``versor_plane_occupancy`` already groups by plane in the slice-0 +diagnostic).
