From b9c54e771306746c140747e5cc4773755108b404 Mon Sep 17 00:00:00 2001 From: Shay Date: Fri, 17 Jul 2026 21:00:11 -0700 Subject: [PATCH] =?UTF-8?q?feat(adr-0246):=20slice=200=20=E2=80=94=20benig?= =?UTF-8?q?n=20nominal-frame=20mismatch=20diagnostic=20(evidence-only)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Diagnostic-only first slice of the ADR-0246 programme: classify WHY benign trajectories mismatch the declared identity frame, using the preflight brief §3 instruments implemented eval-side (induced action A(F), d_orth, d_stab vs locked H_id={I}, typed e4/e5/unclassified residual channels, plane occupancy). No gate, threshold, axis, flag, or corrector changes; serving untouched. Verdict (docs/audit/adr-0246-slice0-mismatch-diagnostic-2026-07-17.md): all 25 live benign/paraphrase turns = foreign_leakage; precision transport immaterial (<=3.6e-5); path accumulation ruled out (per-turn d_stab already 0.15-813); declared frame statistically unspecial vs 32 random control frames => semantic coupling absent, confirming + sharpening the D4 root cause. Two benign sub-populations resolved: 18/25 boost-involved (e5, non-isometric), 7/25 pure e4 conformal tilts (near-isometric). [Verification]: uv run core test --suite smoke -q => 176 passed; tests/test_adr_0246_mismatch_diagnostic.py 16 passed; adjacent identity surfaces (gamma_calibration, identity_manifold, identity_gate wave/runtime/ eval) 75 passed.

The dynamics do not prefer the declared frame over arbitrary alternatives | + +### 3.2 The foreign leakage has two distinct benign sub-populations + +The typed channels + plane occupancy of F resolve structure D4's scalar leakage +could not see: + +**Population A — boost-involved (18/25 turns; the high-leakage cluster).** +ℓ_rms 0.47–0.81, `boost_like` (e5) channel 0.17–0.50, F carrying substantial +grade-2 energy in the **e5-mixing planes** (e15/e25/e35, often ≈ 0.5 of grade-2 +energy), `d_orth` from 0.84 up to 6.6×10⁵ — the action is non-isometric, +cosh-stretching from boost content — and self-alignment frequently driven +negative (to −0.71). Several of these versors also carry O(1) grade-4 energy +(up to 11.1) — general even-grade versors, not simple rotors. + +**Population B — pure e4 tilt (7/25 turns; the moderate cluster).** +ℓ_rms 0.14–0.33, `null_or_conformal` (e4) channel fires with `boost_like` +**exactly 0**, e4-mixing plane occupancy up to 0.98, `d_orth` small (0.06–0.26 — +the action is near-isometric), self-alignment positive (0.80–0.89). These are +genuine conformal/null-direction tilts, not stretches. + +**In both populations the residual is fully accounted for by the typed e4/e5 +channels** — `unclassified` ≤ 1e-9 everywhere. The sandwich output stays exactly +grade-1; there is no numerical contamination. The mismatch is a *lawful property +of the dynamics acting in conformal/boost planes*, not corruption. + +### 3.3 What this pins down mechanistically + +The live cognitive versor's generators live substantially in the spatial↔e4/e5 +mixing planes (e14/e24/e34, e15/e25/e35, e45). Any spatial 3-frame — the declared +one or a random one — gets tilted toward e4 and stretched along e5 by ordinary +benign cognition. That is why: + +- leakage is large and broadband on benign traffic (D4's measurement), +- no threshold separates benign from geometric attacks (D4's 0.346 balanced error), +- and the declared frame is statistically unspecial (this slice's control ensemble). + +The D4 root-cause hypothesis is **confirmed and sharpened**: the failure is not +that the frame is merely mislabeled within the spatial block (an in-span rotation +of labels would show `in_span_unlawful` with ℓ≈0 — observed zero times); it is +that *no fixed spatial grade-1 frame is dynamically stabilized at all*. Identity +preservation as posed by ADR-0244 §2.1 is not a property the current field +evolution possesses with respect to any nominal spatial frame. + +## 4. Consequences for ADR-0246 proper (no decisions taken here) + +Measurement-driven implications, recorded for the ADR-0246 design — explicitly +**not** acted on in this slice: + +1. **An induced-identity action must couple to what the dynamics actually + stabilize, not to a declared spatial frame.** Candidate identity carriers + should be sought among structures the evolution preserves (e.g. invariant + subspaces/eigenmodes of the observed `A(F)` family), then given semantic + assignment — the reverse of the current nominal-label direction. +2. **The e5/boost channel is the dominant benign departure mode** and is + non-isometric (huge `d_orth`); any future lawfulness metric that assumes + isometric action on a fixed frame will misclassify ordinary cognition. + The brief's separation of `d_orth` from `d_stab` is validated by live data. +3. **Path integrity is not the missing piece for the benign story** — per-turn + action is already far from I. The §3.4 ledger remains right for its own + threat model (slow drift), but it will not explain or fix benign refusal. +4. **Precision transport is immaterial** at the current scale (3.6e-5 ceiling); + the f32 serving cast is not implicated in the mismatch. +5. The typed-channel + plane-occupancy instruments transfer directly into the + future `IdentityActionRecord` (brief §4.1) with zero unaccounted residual on + real traffic — the fail-closed `unclassified` channel is empirically quiet. + +## 5. Verification + +- `tests/test_adr_0246_mismatch_diagnostic.py` — 16 passed (ground-truth + classification pins, blade-index pins, A-04 non-import pin, gate-surface + untouched pin: `identity_wave_gate` default off, `_WAVE_LEAKAGE_BOUND` + unchanged at 0.2126624458513829). +- Live capture via instance-local `IdentityCheck` recording subclass on a fresh + empty-vault `ChatRuntime(identity_wave_gate=True, no_load_state=True)` — + measurement-only;
