Merge ADR-0246 Ring-1 implementation into main — flag-off, ADR Proposed
Merges the complete five-unit ADR-0246 stack (authorized by Shay 2026-07-17: "make sure all CI checks pass green then commit and push to remote main, no PR necessary"), executed Fable 5 (scaffold + completion) -> Opus 4.8 (adversarial audit PASS + hardening) -> Sonnet 5/Fable 5 (telemetry + serve integration + §11 feasibility):4941cf18§3 primitives A(F), d_orth, d_stab vs locked H_id={I}, typed channels6efe4ad8§3.4/3.5 path ledger lawful-only composition + hard breaksed54ddda§6.1/6.2 eval suite every preflight case pinned; malformed-F fail-closed47e7eb4eOpus audit+hardening bit-exact math verify; §3.7 admit surface + serve wiring (default-off identity_action_surface); §6.3 discrimination report (honest numbers) (tip) completion §4.1/§4.2 telemetry records; §3.4-step-2 admitted gate; observe-only path serve integration; §11 grounding-feasibility (honest NULL, method validated); ADR body Proposed + packet §8 PENDING GOVERNANCE SCOPE OF THIS MERGE: code lands flag-gated DEFAULT-OFF with flag-off byte-identity proven (all D4 gate surfaces green unchanged; smoke green at every unit). The ADR document is **Proposed** — this merge is NOT a status flip and NOT live activation. identity_wave_gate AND identity_action_surface remain default-off / live activation NOT authorized (D4 ratified limitation + §6.3 evidence: benign/adversarial AUC 0.375, benign false-refusal 1.00; §11: no held-out-stable generator subspace, cross-cohort cosine 0.52 = 87th pctile of chance). Ratification of the ADR (and its requested rulings: F1 composition semantics, ||.||_G convention, hard-break turn ownership, refusal_reason widening) is Shay's, via the acceptance packet. [Verification]: smoke 176 passed (final tree); full targeted battery 228 passed (9 ADR-0246 suites + D4 identity + gamma calibration + identity_gate + telemetry); §6.1/6.2 eval 14/14; artifacts + run logs under docs/audit/.

"""core.physics.identity_action — lawful identity action policy (ADR-0246 §3.2–§3.3).
|
||||
|
||||
Where :mod:`core.physics.identity_manifold` measures *what a versor does* to the
|
||||
value frame (the induced action ``A(F)``, its orthogonality defect ``d_orth``, and
|
||||
typed leakage), this module measures *whether that action is lawful* — how far the
|
||||
induced action sits from the explicitly permitted identity actions ``H_id``.
|
||||
|
||||
The two diagnostics are deliberately never collapsed (ADR-0246 §3.2):
|
||||
|
||||
* ``d_orth`` (in identity_manifold) — detects non-isometric / numerically
|
||||
corrupt action on the subspace. A conditioning check, NOT an authorization.
|
||||
* ``d_stab`` (here) — ``min_{H ∈ H_id} ‖A(F) − H‖_G`` — detects departure from
|
||||
the explicitly *permitted* identity action. This is the lawfulness measure.
|
||||
|
||||
**Locked stabilizer (ADR-0246 §3.3).** For the default identity pack
|
||||
|
||||
H_id = { I }
|
||||
|
||||
the singleton containing only the identity matrix in the axis basis. Algebraic
|
||||
cleanliness ≠ identity lawfulness, so ``-I`` (global inversion), axis
|
||||
permutations, continuous rotations, and arbitrary reweightings are **excluded**.
|
||||
Under a singleton stabilizer there is no continuous projection that "invents" a
|
||||
lawful action: ``d_stab`` is a pass/fail distance, and callers must NOT soft-project
|
||||
``A`` onto ``I`` and then compose the projection as if the turn were lawful.
|
||||
Enlarging ``H_id`` is a future, explicit, reviewed pack/policy change — never an
|
||||
implicit convenience here.
|
||||
|
||||
Pure (numpy + identity_manifold only), deterministic, float64, off-serving. This
|
||||
module owns both the per-turn stabilizer defect (``d_stab``) and the lawful-only
|
||||
path ledger (§3.4/§3.5): the identity path composes ONLY the induced actions of
|
||||
turns certified lawful, refused turns insert break markers (never a soft-projected
|
||||
``I``), and a scope change forces a hard break onto a new chain.

# ADR-0246: Induced Identity Action and Path Integrity
|
||||
|
||||
**Status**: **Proposed** — pending explicit human ratification (provenance guard: no self-Accept; ruling record in the acceptance packet is PENDING)
|
||||
**Date**: 2026-07-17
|
||||
**Authors**: Joshua Shay + multi-model R&D (Fable 5 scaffold → Opus 4.8 adversarial audit + hardening → Sonnet 5/Fable 5 completion; per-model provenance in §9)
|
||||
**Preflight**: `docs/briefs/ADR-0246-induced-identity-action-and-path-integrity-preflight.md` (locked decisions §3, non-goals §7 — all honored; execution log §0a)
|
||||
**Depends on**: ADR-0244 (operator-preservation identity gate, Accepted), ADR-0245 (mechanical sympathy + semantic rigor, Accepted)
|
||||
**Related**: slice-0 evidence `docs/audit/adr-0246-slice0-mismatch-diagnostic-2026-07-17.md` (merged, quarantined diagnostic); Opus audit `docs/audit/adr-0246-slice1-opus-audit-and-hardening.md`
|
||||
|
||||
---
|
||||
|
||||
## 1. Context and problem
|
||||
|
||||
D4 (ADR-0244) built the per-turn operator-preservation floor: does the live
|
||||
cognitive versor `F` preserve the frozen identity frame `I = span(a₁…aₙ)`,
|
||||
measured by per-axis subspace leakage `ℓᵢ` and signed self-alignment `sᵢ`? Two
|
||||
gaps were deliberately left open (preflight §2):
|
||||
|
||||
1. **Lawfulness inside the span** — leakage is blind to in-span reshuffles: a
|
||||
rotor permuting `e1→e2` or inverting `e1→−e1` has `ℓ≈0` yet is not the
|
||||
identity-preserving action.
|
||||
2. **Accumulation across turns** — per-turn thresholds cannot see slow drift:
|
||||
many individually-admissible small rotations compose into a large one.
|
||||
|
||||
This ADR closes both with the **induced action** `A(F)` on the frame, two
|
||||
never-collapsed diagnostics (`d_orth`, `d_stab`), a locked lawful-stabilizer
|
||||
policy `H_id={I}`, typed residual channels, a lawful-only path ledger with hard
|
||||
breaks, a per-turn admit surface, and full per-turn/per-session telemetry — all
|
||||
flag-gated default-off at serve.
|
||||
|
||||
**Claims language (binding, §10 #9 of the preflight):** everything this ADR
|
||||
instruments is **lawfulness relative to the declared frozen frame**. It does
|
||||
NOT establish, and must never be quoted as establishing, any semantic
|
||||
inalienability of the value labels themselves — the shipped axes
|
||||
(`truthfulness=e1`, `coherence=e2`, `reverence=e3`) remain placeholder
|
||||
orthonormal directions with no demonstrated dynamical or semantic grounding
|
||||
(see §6, §7).
|
||||
|
||||
## 2. Decisions (as implemented; preflight §3 locked decisions honored)
|
||||
|
||||
### 2.1 Induced action matrix `A(F)`
|
||||
|
||||
`A_kj(F) = (G⁻¹)_km ⟨a_m, F a_j F̃⟩₀` — the full in-subspace action of the
|
||||
versor on the frame (`core/physics/identity_manifold.py::IdentityManifoldGeometry.induced_action`).
|
||||
Raw/unnormalized: a boost's cosh-stretch shows in column norms and in `d_orth`,
|
||||
never hidden. Bit-exactness against an independent re-derivation was verified
|
||||
in the Opus audit (max discrepancy 0.00e+00).
|
||||
|
||||
### 2.2 Two diagnostics, never collapsed
|
||||
|
||||
- `d_orth(F) = ‖A(F)ᵀ G A(F) − G‖_F` (`orthogonality_defect`) — G-isometry /
|
||||
numerical-integrity check. **Not** an authorization policy.
|
||||
- `d_stab(F) = min_{H∈H_id} ‖A(F) − H‖_G` (`identity_action.py::stabilizer_defect`)
|
||||
— the lawfulness distance from the permitted identity actions.
|
||||
|
||||
**Norm convention (ruling requested — §7 item 1):** `‖M‖_G ≡ ‖G^{1/2} M G^{-1/2}‖_F`,
|
||||
computed via `eigh` of the SPD Gram; reduces exactly to Frobenius at `G=I`
|
||||
(the only shipped pack). This is the metric-consistent choice (invariant under
|
||||
G-orthogonal reparameterization of the axes); ratifying this ADR ratifies the
|
||||
convention.
|
||||
|
||||
### 2.3 Lawful stabilizer — locked singleton
|
||||
|
||||
`H_id = {I}` (`IdentityStabilizer.singleton`), hardcoded in the path-advance
|
||||
(no enlargement parameter exists). `−I`, permutations, `O(n)`/`SO(n)`
|
||||
rotations, and reweightings are excluded; enlarging `H_id` is a future explicit
|
||||
reviewed pack/policy change. No soft-projection of an unlawful `A` onto `I`
|
||||
exists anywhere (grep-audited; pinned by tests).
|
||||
|
||||
### 2.4 Path integrity — lawful-only composition (F1 semantics, ratification-relevant)
|
||||
|
||||
`advance_identity_path` (§3.4/§3.5) composes the session path
|
||||
`A_path = A_T ⋯ A_1` from **only** the turns certified lawful, where lawful ≡
|
||||
**admitted by the per-turn policy (§3.4 step 2)** AND `d_stab(A_t) ≤ ε_turn`.
|
||||
Refused or ill-conditioned turns insert a **break marker** and are excluded —
|
||||
never a soft-projected `I` masquerading as a pass; the raw product is exposed
|
||||
only as `raw_path_product` (forensic; a test fails if it ever equals the lawful
|
||||
path in a mixed sequence).
|
||||
|
||||
**F1 composition semantics (audit finding, hereby put to ratification):** a
|
||||
lawful turn composes its *actual certified action* `A_t`, not a literal element
|
||||
of `H_id`. This is required, not convenience — composing literal `I`s would
|
||||
make `A_path ≡ I` and blind the ledger to exactly the slow drift it exists to
|
||||
catch. "Compose lawful `H_t`" in preflight §3.4-step-4 is READ as "compose the
|
||||
per-turn actions that were certified lawful."
|
||||
|
||||
**Hard breaks (§3.5):** a new chain (fresh `chain_id`, path not continued)
|
||||
starts on any change of pack content digest / geometry version / gate+policy
|
||||
version / session — each dimension is pinned by a test. **Turn ownership at a
|
||||
hard break (ruling requested — §7 item 3):** the boundary turn belongs to the
|
||||
NEW chain (it composes into the fresh path if lawful). Biography holonomy stays
|
||||
a separate process; nothing here rewrites identity axes.
|
||||
|
||||
**Budgets:** `d_stab(A_t) ≤ ε_turn` per turn and `d_stab(A_path) ≤ ε_session`
|
||||
per session — both ε are **UNCERTIFIED placeholders** (§5), so the session
|
||||
verdict (`session_admit`) is telemetry only.
|
||||
|
||||
### 2.5 Typed residual channels — pinned blade map
|
||||
|
||||
On each axis rejection `r = F a F̃ − P_I(F a F̃)` (`typed_residual_energy`),
|
||||
energy splits into: `null_or_conformal` (e4 = grade-1 index **4**),
|
||||
`boost_like` (e5 = grade-1 index **5**), `spatial_foreign` (grade-1 spatial
|
||||
slots **1/2/3** outside the pack's axis support), `unclassified` (everything
|
||||
else — fail-closed, **no correction policy ever attaches to it**). Blade
|
||||
indices are pinned against `algebra.cl41.basis_vector` in tests
|
||||
(`test_blade_index_constants_match_algebra`). For the default full-span pack,
|
||||
`spatial_foreign` is **tautologically zero** (the rejection is orthogonal to
|
||||
the whole spatial block); it fires correctly for reduced-support packs —
|
||||
resolved and pinned (§7 item 2).
|
||||
|
||||
### 2.6 Per-turn admit surface (§3.7) — admit-or-abstain only
|
||||
|
||||
`evaluate_admission(geometry, F, policy)` admits iff `d_orth ≤ orth_tol` AND
|
||||
`d_stab ≤ ε_turn` AND `leakage_rms ≤ γ_id` AND `max ℓᵢ ≤ τ_max` AND
|
||||
`min sᵢ ≥ s_min` AND no boundary breach AND no unclassified-channel firing;
|
||||
otherwise refuses naming every failed condition. **No geometric `C_id`
|
||||
corrector exists** — the egress model remains D4's
|
||||
`conjugate_correct(refuse=True)` abstention. A malformed versor raises
|
||||
`MalformedVersorError` (fail-closed; never a silent legacy fallback when a
|
||||
wave field was supplied).
|
||||
|
||||
### 2.7 Serve wiring — flag-gated, default-off, byte-identical off
|
||||
|
||||
- New `RuntimeConfig.identity_action_surface: bool = False` (separate from
|
||||
`identity_wave_gate`; acts only when the wave gate is also on).
|
||||
- `chat/runtime.py → IdentityCheck.check(admission_policy=…) → _wave_field_score`:
|
||||
a §3.7 refusal folds into `flagged`, so the existing `would_violate` egress
|
||||
abstains. `IdentityScore` gains `action_surface_active`/`d_orth`/`d_stab`/
|
||||
`action_record` with legacy defaults — flag-off is byte-identical (all D4
|
||||
gate surfaces green unchanged; smoke green post-wiring).
|
||||
- The session path ledger is advanced per wave-path turn under the same flags,
|
||||
**observe-only** (`advance_session_identity_path`): `session_admit` is
|
||||
telemetry, never an egress decision, because `ε_session` is uncertified and
|
||||
live activation remains unauthorized.
|
||||
|
||||
### 2.8 Telemetry (§4.1/§4.2/§4.3)
|
||||
|
||||
- `IdentityActionRecord` (schema `identity_action_v1`): turn/trajectory/pack
|
||||
ids, **full-SHA-256** pack-content digest + `field_digest` (LE f64 bytes) +
|
||||
`record_digest` (canonical JSON, no `default=str`), geometry/gate/policy
|
||||
versions (`policy_version = AdmissionPolicy.version_id()`, full SHA-256 of
|
||||
the exact threshold set), `A_raw`, `d_orth`, `d_stab`, leakage/self-align
|
||||
vectors, typed channels, `admitted`, `refusal_reason` (all failed conditions
|
||||
joined with `;` — a deliberate widening of the preflight's singular field so
|
||||
multi-condition refusals lose nothing), `lawful_action ∈ {"I","none"}`
|
||||
(never a matrix), `path_break`.
|
||||
- `IdentityPathLedger` (schema `identity_path_v1`): `chain_id` (full SHA-256
|
||||
of scope + chain index), lawful path, `d_stab_path`, composed/break counts,
|
||||
`session_admit`, `ledger_digest`.
|
||||
- The JSONL turn serializer emits `identity_d_*`/`identity_action_*`/
|
||||
`identity_path_*` keys **only when the respective path ran** — the flag-off
|
||||
wire format is byte-identical (pinned by tests).
|
||||
|
||||
## 3. Evidence — §6 eval matrix (all green) and the honest discrimination result
|
||||
|
||||
- **§6.1 synthetic geometric suite** (9 cases) + **§6.2 path/holonomy suite**
|
||||
(5 cases): `evals/adr_0246_geometric_suite` — 14/14; every construction in
|
||||
the preflight tables pinned individually (identity versor, π-inversion
|
||||
`s=−1`, 90° permutation `s=0`, mild drift, e14 tilt, e15 boost,
|
||||
near-singular Gram → `ManifoldConditioningError`, malformed F → typed error;
|
||||
lawful sequence, accumulation-to-session-refusal, interleaved breaks,
|
||||
pack-change hard break, raw≠lawful forensic).
|
||||
- **§6.3 discrimination report** (`evals/adr_0246_discrimination`;
|
||||
live benign n=13, adversarial n=8, synthetic-near-identity control n=5;
|
||||
artifact `docs/audit/artifacts/adr-0246-slice1-discrimination-report.json`):
|
||||
|
||||
| benign pass | false refusal | adversarial detect | control pass | d_stab AUC (95% CI) |
|
||||
|---|---|---|---|---|
|
||||
| **0.00** | **1.00** | 1.00 | **1.00** | **0.375** [0.15, 0.62] |
|
||||
|
||||
**Honest finding:** on the declared placeholder frame the admit surface
|
||||
refuses benign and adversarial versors **alike** — benign cognition sits
|
||||
~18× farther from the frame (mean `d_stab` 27.8) than the crafted attacks
|
||||
(1.55), so `d_stab` discriminates *below chance*. The near-identity control
|
||||
passing 100% proves the mechanism is sound; the failure is entirely that
|
||||
benign cognition does not live near the declared frame. A refuse-everything
|
||||
gate trivially "detects" attacks but is **not a discriminator**.
|
||||
- **§11 grounding-feasibility study** (`evals/adr_0246_grounding_feasibility`;
|
||||
artifact `docs/audit/artifacts/adr-0246-grounding-feasibility-report.json`):
|
||||
fixed TRAIN (live benign, n=13) / HELD-OUT (independent paraphrase cohort,
|
||||
n=12) / ADVERSARIAL (n=8) splits; bivector-block generator proxy (numpy-only;
|
||||
exact for simple rotors/boosts, first-order otherwise); sample-size-calibrated
|
||||
null distribution (200 trials of independent pure-noise cohort pairs at the
|
||||
real n) with a shared-basis positive recovery control; precision pairs
|
||||
(f64↔f32) and per-plane generator-energy analysis.
|
||||
|
||||
**Result: NULL, with the method itself validated.** The positive control
|
||||
(two independent cohorts sharing one true rank-2 subspace) recovers at
|
||||
cosine 0.9995 — the 100th percentile of the same-sample-size null (p95 =
|
||||
0.60) — so the instrument can find real structure at n=12. The real cohorts
|
||||
do not show it: TRAIN→HELD-OUT top-2 cosine 0.52 sits at only the **87th
|
||||
percentile of pure chance** (need ≥ 95th); residual-based discrimination is
|
||||
AUC **0.49** (chance; CI [0.21, 0.77]); generator energy is spread across
|
||||
all 10 bivector planes in both cohorts; precision transport is immaterial
|
||||
(max bivector delta 6.9e-7). Benign cognition has no small, stable,
|
||||
cohort-independent generator subspace detectable at this sample size — the
|
||||
D4/slice-0/§6.3 finding now holds at the GENERATOR level too. Threshold
|
||||
tuning cannot produce a discriminating gate; a revised implementation
|
||||
contract is not justified on this evidence. The full `honest_finding` text
|
||||
in the artifact is binding for any downstream claim; a much larger,
|
||||
pre-registered cohort would be needed to rule out a subtle real effect.
|
||||
|
||||
## 4. Operational status (machine-readable)
|
||||
|
||||
```yaml
|
||||
identity_action_surface:
|
||||
implementation: proposed # this ADR; code merged flag-off
|
||||
live_activation: not_authorized # D4 ratified limitation carries over
|
||||
default: off
|
||||
blocker: >
|
||||
§6.3 shows no benign/adversarial separation on the declared frame
|
||||
(AUC 0.375, benign false-refusal 1.00); thresholds beyond gamma_id
|
||||
are uncertified placeholders.
|
||||
activation_requires:
|
||||
- held-out-stable, safety-relevant grounding result (§11 programme)
|
||||
- calibrated epsilon_turn/epsilon_session/tau_max/s_min certificates
|
||||
- renewed discrimination evidence with acceptable benign refusal rate
|
||||
- explicit human ratification
|
||||
identity_wave_gate:
|
||||
unchanged: true # ADR-0244 Accepted-with-limitation posture untouched
|
||||
```
|
||||
|
||||
## 5. Uncertified placeholders (enumerated; never live defaults)
|
||||
|
||||
| Constant | Value | Status |
|
||||
|---|---|---|
|
||||
| `gamma_id` | 0.2126624458513829 | **CERTIFIED** (D4 Phase 3 Fibonacci certificate `0079b5f2…`); pinned equal to `identity._WAVE_LEAKAGE_BOUND` by test |
|
||||
| `epsilon_turn` | 0.1 | placeholder |
|
||||
| `epsilon_session` | 0.3 | placeholder |
|
||||
| `tau_max` | = γ_id | placeholder |
|
||||
| `s_min` | 0.0 | matches D4's fixed orientation floor (geometric invariant, not tuned) |
|
||||
| `orth_tol` | 1e-6 | placeholder |
|
||||
| `unclassified_tol` | 1e-6 | placeholder |
|
||||
|
||||
`AdmissionPolicy.placeholder_default()` carries `calibrated=False`; a serve
|
||||
gate must never treat an uncalibrated policy as license to activate.
|
||||
|
||||
## 6. What this ADR does NOT do (preflight §7 non-goals — all honored)
|
||||
|
||||
No geometric `C_id`/corrector; no Ring-2 residual protocol; no semantic axis
|
||||
grounding or pack redesign; no biography-holonomy merge; no atlas/VSWR work;
|
||||
no analytic cast reactance; no grade-1 versor projection (proven vacuous); no
|
||||
indefinite-norm leakage; no `H_id` enlargement; no soft-projection; no
|
||||
default-on serve gate; no Smith-chart algebra; no status flip of ADR-0244/0245.
|
||||
|
||||
## 7. Resolved and open questions
|
||||
|
||||
1. **`‖·‖_G` convention** — implemented as `‖G^{1/2}MG^{-1/2}‖_F`; **ratify
|
||||
with this ADR** (§2.2).
|
||||
2. **`spatial_foreign` channel** — RESOLVED: tautologically zero for the
|
||||
default full-span pack; fires correctly for reduced-support packs (pinned:
|
||||
`test_spatial_foreign_channel_fires_for_reduced_support_pack`).
|
||||
3. **Hard-break turn ownership** — implemented as new-chain; **ratify with
|
||||
this ADR** (§2.4).
|
||||
4. **Malformed-F/gate routing** — the D4 wave-path validator raises before the
|
||||
admission surface runs; `MalformedVersorError` from the pure primitives
|
||||
propagates fail-closed. No silent legacy fallback exists when a wave field
|
||||
was supplied. Unifying the two typed errors is left to a future cleanup.
|
||||
5. **OPEN (future ADR):** semantic axis grounding — blocked on a positive §11
|
||||
result at adequate sample size; `ε` calibration; `H_id` policy products.
|
||||
|
||||
## 8. Consequences
|
||||
|
||||
- The identity organ now measures *everything* the preflight demanded —
|
||||
in-span lawfulness, isometry integrity, typed foreign leakage, and
|
||||
path accumulation — with serve byte-identity preserved and zero live policy
|
||||
change. What it measures says, honestly: the declared frame is not the
|
||||
structure live cognition preserves, so the gate stays off and the next
|
||||
investment belongs to grounding, not thresholds.
|
||||
- All future identity work inherits content-addressed, full-digest telemetry
|
||||
(records + ledger) and a single pure source of truth for the §3 primitives.
|
||||
|
||||
## 9. Provenance
|
||||
|
||||
Fable 5: slice-0 diagnostic; §3 primitives + §3.4/3.5 ledger + §6.1/6.2 suites
|
||||
(RED-first); this completion pass. Opus 4.8: adversarial audit (bit-exact math
|
||||
re-derivation; H_id/soft-projection/scope-creep verification), F1 finding,
|
||||
§3.7 surface + serve wiring, §6.3 discrimination report. Sonnet 5: §4.1/§4.2
|
||||
telemetry records, `admitted` gate on the ledger (F1-adjacent §3.4-step-2
|
||||
compliance), path serve integration (observe-only), §11 feasibility study
|
||||
design. Every stage: local-first CI (smoke + targeted suites) before commit;
|
||||
no self-Accept at any point.

|

## 1. Scope of what is being put to ruling
|
||||
|
||||
Accepting this ADR accepts: the §3 primitives and their pinned blade map; the
|
||||
locked `H_id={I}` stabilizer; the **`‖·‖_G = ‖G^{1/2}MG^{-1/2}‖_F` norm
|
||||
convention**; the **F1 composition semantics** (lawful turns compose their raw
|
||||
*certified* action, never a literal `I`); the **admitted-gate** on composition
|
||||
(§3.4 step 2); **hard-break turn ownership = new chain**; the §3.7
|
||||
admit-or-abstain surface; the flag-gated serve wiring (default-off,
|
||||
byte-identical off); and the §4.1/§4.2 telemetry contracts.
|
||||
|
||||
It does **NOT** accept or authorize: live activation of `identity_wave_gate`
|
||||
or `identity_action_surface` (both stay default-off; the D4 ratified
|
||||
limitation carries over); any calibration of the placeholder thresholds; any
|
||||
semantic claim about the value labels ("lawfulness relative to the declared
|
||||
frozen frame" only); any `H_id` enlargement or geometric corrector.
|
||||
|
||||
## 2. §10 acceptance criteria — status
|
||||
|
||||
| # | Criterion | Status |
|
||||
|---|---|---|
|
||||
| 1 | §6 synthetic + path suites green; discrimination report attached | ✅ 14/14 eval cases; §6.3 + §11 artifacts under `docs/audit/artifacts/` |
|
||||
| 2 | `H_id={I}` enforced, no silent enlargement | ✅ singleton hardcoded; no enlargement path; grep-audited + pinned |
|
||||
| 3 | Lawful-only composition proven by tests that fail if raw product used | ✅ `test_lawful_path_equals_lawful_subproduct_not_raw`, `test_raw_product_differs_from_lawful`, §3.4-step-2 pin |
|
||||
| 4 | Ledger hard-breaks on pack/geometry/policy/session change | ✅ parametrized over every scope dimension |
|
||||
| 5 | Flag-off serve path byte-identical | ✅ egress/action-record/path tests + all D4 gate surfaces green unchanged + smoke |
|
||||
| 6 | No geometric `C_id`; admit-or-abstain only | ✅ no corrector exists; refusal folds into the existing `would_violate` egress |
|
||||
| 7 | Typed residual channels pinned to explicit blade indices | ✅ e4=idx 4, e5=idx 5, spatial=idx 1/2/3; pinned vs `algebra.cl41` |
|
||||
| 8 | Smoke + relevant lanes local-first; `[Verification]` on commits | ✅ every commit in the stack; final run log `docs/audit/artifacts/adr-0246-slice1-complete-runlog.txt` |
|
||||
| 9 | Claims language: lawfulness-relative-to-frame, never semantic inalienability | ✅ binding in ADR §1; enforced in report code + tests |
|
||||
| 10 | Explicit human ratification for status flip | ⏳ THIS PACKET — §8 below |
|
||||
|
||||
## 3. Verification summary (see run log for actual output)
|
||||
|
||||
- §6.1/§6.2 eval harness: **14/14** `all_passed=True`.
|
||||
- ADR-0246 test suites (induced-action incl. spatial-foreign resolution,
|
||||
path-ledger incl. raw-sneak + admitted-gate, geometric suite, admission +
|
||||
honest-verdict pins, egress wiring, action-record §4.1, path serve
|
||||
integration, grounding feasibility, mismatch diagnostic): **all green**.
|
||||
- Adjacent D4 identity surfaces + telemetry suites: **green unchanged**
|
||||
(serve byte-identity).
|
||||
- `uv run core test --suite smoke -q`: **green** (appended to run log).
|
||||
|
||||
## 4. The honest §6.3 discrimination numbers (binding)
|
||||
|
||||
Benign pass **0.00** · false refusal **1.00** · adversarial detect 1.00 ·
|
||||
near-identity control pass **1.00** · `d_stab` AUC **0.375** [0.15, 0.62] —
|
||||
benign cognition sits ~18× farther from the declared frame than crafted
|
||||
attacks. The gate mechanism is sound; the frame is not what live cognition
|
||||
preserves. A refuse-everything gate is not a discriminator; activation stays
|
||||
unauthorized.
|
||||
|
||||
## 5. The §11 grounding-feasibility verdict (binding, verbatim from the artifact)
|
||||
|
||||
> NULL (n_train=13, n_held_out=12): the top-2 generator-proxy subspace found
|
||||
> on TRAIN does NOT reliably reproduce on the independently-collected HELD-OUT
|
||||
> cohort — cosine similarity 0.52 sits at only the 87th percentile of what two
|
||||
> INDEPENDENT pure-noise cohorts of the same size produce by chance (need >=
|
||||
> 95th) and/or does not clear the discrimination bar (AUC 0.49, 95% CI [0.21,
|
||||
> 0.77]). This is consistent with — and sharpens — the D4/slice-0/§6.3 finding
|
||||
> at the GENERATOR level (not just the induced-action level): benign cognition
|
||||
> does not have a small, stable, cohort-independent generator subspace
|
||||
> detectable at this sample size. Threshold tuning on the current pack cannot
|
||||
> produce a discriminating gate; this feasibility study does not find grounds
|
||||
> to draft a revised ADR-0246 implementation contract. A much larger cohort
|
||||
> (this study used n<=13 per real cohort) would be needed to rule out a real
|
||||
> but subtle effect, rather than to overturn this null.
|
||||
|
||||
Method validated by sample-size-calibrated controls: shared-basis positive
|
||||
pair recovers at cosine 0.9995 (100th percentile of the null; null p95 0.60 at
|
||||
n=12). Precision transport immaterial (6.9e-7).
|
||||
|
||||
## 6. Rulings requested alongside Proposed→Accepted
|
||||
|
||||
1. `‖·‖_G` convention (ADR §2.2).
|
||||
2. F1 composition semantics + admitted-gate reading of §3.4 (ADR §2.4).
|
||||
3. Hard-break turn ownership = new chain (ADR §2.4).
|
||||
4. The refusal_reason multi-condition widening (ADR §2.8).
|
||||
|
||||
## 7. Operational limitation carried forward
|
||||
|
||||
`identity_wave_gate` AND `identity_action_surface` remain **default-off / live
|
||||
activation NOT authorized**. Activation prerequisites (all required): a
|
||||
positive, held-out-stable, safety-relevant grounding result at adequate sample
|
||||
size; calibrated ε/τ/s certificates; renewed discrimination evidence with
|
||||
acceptable benign refusal; explicit human ratification.
|
||||
|
||||
## 8. RULING RECORD

# ADR-0246 Slice-1 — Opus 4.8 Audit, Hardening & Discrimination Report
|
||||
|
||||
**Reviewer:** Opus 4.8. **Branch:** `feat/adr-0246-slice1-hardened` (stacked on
|
||||
`feat/adr-0246-slice1-scaffold`, unmerged). **Not a PR, not merged, no status
|
||||
flip.** Review gate only — ratification is human (Shay).
|
||||
**Audited artifact:** Fable 5's `feat/adr-0246-slice1-scaffold`.
|
||||
|
||||
---
|
||||
|
||||
## 1. Step-1 adversarial audit — VERDICT: PASS (one documentation finding)
|
||||
|
||||
Nothing was trusted from Fable's run log; every claim was reproduced.
|
||||
|
||||
| Check | Method | Result |
|
||||
|-------|--------|--------|
|
||||
| D4 closed (hard gate) | independent `git cat-file`/status on `main` | ✅ both acceptance packets on `main`; ADR-0244 Accepted/ratified; `main @ 04d67ca5` |
|
||||
| `A(F)`, `d_orth`, `d_stab`, typed channels correct | **re-derived from §3.1/3.2/3.6 from scratch** (independent sandwich/Gram/projection) and diffed vs impl | ✅ **bit-exact, max discrepancy 0.00e+00** |
|
||||
| `H_id={I}` genuinely locked in code | read `IdentityStabilizer`, `advance_identity_path` | ✅ singleton hardcoded in the path; **no enlargement parameter or path**; grep found no enlargement/permutation/soft-projection code |
|
||||
| Path composes lawful only, never raw, no soft-`I` | read composition; grep | ✅ lawful turns compose; refused turns → `path_break`, excluded; `a_path` untouched on refuse |
|
||||
| Placeholders logged, not baked | read policy/eval | ✅ `PLACEHOLDER_*` marked; `PathBudget` always caller-supplied |
|
||||
| §7 scope creep / serve byte-identity | full `git diff main..scaffold`; per-function diff | ✅ **no `chat/runtime.py`, `identity.py`, or flag change**; serve-called geometry functions untouched (additions only) |
|
||||
| §6.1/§6.2 matrix reproduced | ran from clean tree | ✅ 14/14 eval cases; 64 tests |
|
||||
|
||||
### Finding F1 (documentation, NOT a code bug)
|
||||
`advance_identity_path` composes the **raw certified action** `A_t`
|
||||
(`a_path = A_t @ a_path`), not a literal `I`. This is **required and correct** —
|
||||
composing `I`s would make `A_path ≡ I` and defeat the slow-drift detection that is
|
||||
the ledger's whole purpose (§2 gap). But it departs from a literal reading of
|
||||
§3.4-step-4's `H_t ∈ H_id` notation and was undocumented. **Correction applied:**
|
||||
an explicit "Composition semantics (ratification-relevant)" paragraph now states
|
||||
the reading in the docstring; the ADR body should ratify it (see §4 handoff).
|
||||
|
||||
No locked decision (§3) or non-goal (§7) was violated to make anything pass.
|
||||
|
||||
---
|
||||
|
||||
## 2. Hardening & additions (this branch) — diff-style note
|
||||
|
||||
Every change vs Fable's scaffold, and why:
|
||||
|
||||
| File | Change | Why |
|
||||
|------|--------|-----|
|
||||
| `identity_action.py` | **F1 docstring** on `advance_identity_path` | ratify the raw-certified-action composition (audit finding) |
|
||||
| `identity_action.py` | **§3.7 admit surface**: `CERTIFIED_GAMMA_ID`, `PLACEHOLDER_*`, `AdmissionPolicy` (`calibrated=False`), `AdmissionResult`, `evaluate_admission` | pure, testable admit-or-abstain surface (§3.7) — the reusable core for the discrimination report and the future serve wiring. No corrector. |
|
||||
| `evals/adr_0246_discrimination/` | **§6.3 discrimination report** (new) | honest benign-vs-adversarial numbers with bootstrap-CI AUC (§6.3/§10) |
|
||||
| `tests/test_adr_0246_admission.py` | pins for `evaluate_admission` + the honest verdict + γ_id-drift guard | fail loudly if the surface or the honesty claim regresses |
|
||||
| `tests/test_adr_0246_path_ledger.py` | **raw-sneak hardening test** | fails if a raw product ever enters `A_path_lawful` (Step 2.3) |
|
||||
|
||||
Nothing here touches serve, flags, `H_id`, or adds a corrector. `evaluate_admission`
|
||||
lives in the pure `identity_action.py`; γ_id is pinned equal to
|
||||
`identity._WAVE_LEAKAGE_BOUND` by a test so it cannot drift.
|
||||
|
||||
---
|
||||
|
||||
## 3. §6.3 Discrimination report — HONEST numbers (no inflation)
|
||||
|
||||
Full artifact: `docs/audit/artifacts/adr-0246-slice1-discrimination-report.json`
|
||||
(live benign cohort n=13, adversarial n=8, synthetic-near-identity control n=5;
|
||||
policy = placeholder, `calibrated=False`).
|
||||
|
||||
| Metric | Value |
|
||||
|--------|-------|
|
||||
| benign pass rate | **0.00** |
|
||||
| false refusal rate | **1.00** |
|
||||
| adversarial detection rate | 1.00 |
|
||||
| synthetic-near-identity pass rate (control) | **1.00** |
|
||||
| `d_stab` AUC (adversarial vs benign) | **0.375**, 95% CI [0.15, 0.62] |
|
||||
| `leakage_rms` AUC | 0.18, 95% CI [0.04, 0.39] |
|
||||
| benign `d_stab` (min/mean/max) | 0.15 / **27.8** / 228 |
|
||||
| adversarial `d_stab` (min/mean/max) | 0.46 / **1.55** / 2.83 |
|
||||
|
||||
**Honest finding (verbatim in the report):** the §3.7 admit surface on the declared
|
||||
placeholder frame refuses benign and adversarial versors **alike** — benign
|
||||
false-refusal is 100% and `d_stab` does **not** separate the classes (AUC 0.375 is
|
||||
*below* chance: real benign cognition sits ~18× farther from the identity frame
|
||||
than the crafted attacks do). A gate that refuses everything trivially "detects"
|
||||
every attack but **is not a discriminator**. The synthetic-near-identity control
|
||||
passing at 100% confirms the gate *mechanism* is sound — the failure is entirely
|
||||
that benign cognition does not live near the declared frame. This reproduces and
|
||||
sharpens the D4 / slice-0 result at the fuller §3.7 surface.
|
||||
|
||||
**Claims language (§10 #9), enforced in code and report:** this supports only
|
||||
*"lawfulness relative to the declared frozen frame."* It does **not** support any
|
||||
claim of *"semantic inalienability of the value labels."* The gate must stay
|
||||
default-off; usable separation requires the §11 dynamics-grounding work — **not**
|
||||
threshold tuning.
|
||||
|
||||
---
|
||||
|
||||
## 4. §3.7 egress serve wiring (Steps 2.1/2.2) — DONE (Opus)
|
||||
|
||||
Wired the fuller admit surface into the live gate, flag-gated + default-off +
|
||||
byte-identical:
|
||||
- New **default-off** flag `identity_action_surface` in `core/config.py`
|
||||
`RuntimeConfig` (separate from `identity_wave_gate`; documented as uncalibrated /
|
||||
not authorized live).
|
||||
- Threaded an `AdmissionPolicy` (`placeholder_default()`, `calibrated=False`)
|
||||
through `chat/runtime.py` → `IdentityCheck.check(..., admission_policy=)` →
|
||||
`_wave_field_score`. Only acts when `identity_wave_gate` is also on (a
|
||||
`wave_field` exists).
|
||||
- On the wave path with the policy present, `evaluate_admission(...)` runs; a
|
||||
refusal folds into `flagged`, so the **existing** `would_violate` /
|
||||
`conjugate_correct(refuse=True)` egress abstains — **admit-or-abstain, no
|
||||
corrector**. `MalformedVersorError` from the primitives propagates as a
|
||||
fail-closed refusal.
|
||||
- `IdentityScore` gained optional `action_surface_active` / `d_orth` / `d_stab`
|
||||
with legacy defaults, so flag-off is byte-identical.
|
||||
|
||||
Verified: `tests/test_adr_0246_egress_wiring.py` (flag default-off; flag-off
|
||||
`check()` byte-identical incl. default §3.7 fields; flag-on refuses a tilt and
|
||||
admits true near-identity) + **all D4 gate surfaces green unchanged** (wave /
|
||||
runtime / eval / `test_identity_gate`) — serve byte-identity confirmed.
|
||||
**Guardrail:** `calibrated=False` + flag default-off ⇒ not live-authorized; the §3
|
||||
discrimination numbers are the evidence it must stay off pending §11 + calibration.
|
||||
|
||||
## 4c. Handoff to Sonnet 5 — remaining ADR-0246 work
|
||||
|
||||
1. **§4.1 `IdentityActionRecord` per-turn telemetry** — not built (only the §4.2
|
||||
`IdentityPathLedger` exists). Add the per-turn record (field/record digests,
|
||||
gate/policy versions, the §3.7 measures) and emit it only when the wave/action
|
||||
path ran (preserve flag-off wire format, §4.3). Optionally surface `d_orth`/
|
||||
`d_stab`/typed channels through the telemetry serializer.
|
||||
2. **Path-ledger ↔ serve integration** — the ledger (`advance_identity_path`) is
|
||||
pure and unit-tested but is not yet driven per-turn from `chat/runtime.py`
|
||||
(session-scoped chain, hard-break on pack/geometry/policy/session). Wire it
|
||||
flag-gated + off, using the §3.5 scope keys, if a session path budget is wanted.
|
||||
3. **ADR-0246 body + acceptance packet** — draft `docs/adr/ADR-0246-...md` as
|
||||
**Proposed** (no self-Accept — provenance guard). Must: state the F1 composition
|
||||
semantics explicitly; use the §10 claims language ("lawfulness relative to the
|
||||
declared frozen frame"); carry the honest §6.3 numbers; enumerate the placeholder
|
||||
ε's/τ's as uncalibrated. Acceptance packet per §10; §8 RULING PENDING.
|
||||
4. **§11 grounding-feasibility study** (the larger research workstream) — does a
|
||||
held-out-stable, safety-relevant dynamics-invariant structure exist (fixed
|
||||
cohort splits, synthetic recovery controls, typed e4/e5 generator analysis,
|
||||
precision pairs, adversarial discrimination)? This is the only path to a gate
|
||||
that discriminates; the §6.3 report shows threshold tuning cannot get there.
|
||||
5. **Open uncertainties still needing a ruling** (Fable notes §4, unchanged):
|
||||
general-pack `‖·‖_G` convention; structurally-empty `spatial_foreign` channel;
|
||||
hard-break turn ownership; malformed-F/gate-routing boundary. Carry into the ADR.
|
||||
|
||||
---
|
||||
|
||||
## 5. Verification (run log: `docs/audit/artifacts/adr-0246-slice1-hardened-runlog.txt`)
|
||||
- §6.1/§6.2 eval matrix → 14/14, `all_passed=True`.
|
||||
- ADR-0246 suites (admission, egress wiring, induced-action, path-ledger incl.
|
||||
raw-sneak hardening, geometric suite, mismatch diagnostic) → **80 passed**.
|
||||
- Egress wiring + all D4 gate surfaces (wave/runtime/eval/`test_identity_gate`) →
|
||||
**47 passed** — flag-off byte-identity confirmed (D4 gate unchanged).
|
||||
- `uv run core test --suite smoke -q` → **176 passed** (post-serve-wiring).
|
||||
- §6.3 discrimination report → the honest numbers in §3 above.

## 0a. Post-D4 execution sequencing (actual — 2026-07-17)
|
||||
|
||||
D4 closed and was ratified; this brief is now the live plan. The R&D assessment's
|
||||
one-shot "build the whole Ring-1 gate machinery" is being executed as small,
|
||||
verified units, and the brief's own **§11 semantic-grounding question was promoted
|
||||
to run as a consumer of the §3 apparatus** (not a re-sequenced blocker), because
|
||||
D4 Phase 3 + slice 0 proved no fixed spatial frame is dynamically stabilized —
|
||||
building a lawfulness gate on the declared frame before knowing whether *any*
|
||||
structure is stabilized would instrument lawfulness on a frame the dynamics ignore
|
||||
(the "instruments ≠ meaning" trap, §2 / §11).
|
||||
|
||||
| Unit | Scope | Status |
|
||||
|------|-------|--------|
|
||||
| **Slice 0** — mismatch diagnostic | evidence-only classification of the benign mismatch (foreign leakage vs in-span-unlawful vs numerical vs path vs semantic-coupling-absent) | **merged** `main` (quarantined diagnostic artifact); found: structural e4/e5 foreign leakage, declared frame dynamically unspecial |
|
||||
| **§3 primitives** | pure `A(F)`, `d_orth`, `d_stab` vs locked `H_id={I}`, typed residual channels in `core/physics/identity_manifold.py` + `identity_action.py`; slice-0 eval rewired to consume them (single source of truth) | **committed** `feat/adr-0246-induced-action-primitives` (RED→GREEN, off-serving, flag untouched) — awaiting review |
|
||||
| **§3.4/§3.5 path ledger** | lawful-only composition + hard breaks: `PathBudget`, `IdentityChainScope`, `IdentityPathLedger`, `advance_identity_path` in `identity_action.py`; refused turns = break markers (never soft-projected `I`); scope change = hard break onto new chain | **committed** `feat/adr-0246-path-ledger` (RED→GREEN, off-serving), stacked on primitives — awaiting review |
|
||||
| **§6.1/§6.2 eval matrix (scaffold)** (this unit) | runnable synthetic geometric + path/holonomy suites (`evals/adr_0246_geometric_suite/`), every §6.1/§6.2 case pinned; malformed-F fail-closed (`MalformedVersorError`) | **draft scaffold** `feat/adr-0246-slice1-scaffold` (14/14 eval cases + 114 identity-surface tests + smoke green) — awaiting Opus/Shay audit (`docs/handoff/adr-0246-slice1-scaffold-notes.md`) |
|
||||
| **§3.7 gate admit surface + §6.3 discrimination** (Opus audit+hardening) | `AdmissionPolicy`/`evaluate_admission` (§3.7 pure surface); wired into `identity.py`/`chat/runtime.py` behind new default-off `identity_action_surface` (byte-identical flag-off, admit-or-abstain, no corrector); §6.3 discrimination report | **committed** `feat/adr-0246-slice1-hardened` — audit PASS, honest finding: gate refuses benign+adversarial alike (AUC 0.375, benign d_stab 18× adversarial), stays off; awaiting Shay ratification (`docs/audit/adr-0246-slice1-opus-audit-and-hardening.md`) |
|
||||
| **§4.1/§4.2 telemetry + path serve integration** (completion pass) | `IdentityActionRecord` (full digests, `policy_version=version_id()`, multi-condition `refusal_reason`); `manifold_content_digest` + geometry/gate version ids; §3.4-step-2 `admitted` gate on the ledger; `advance_session_identity_path` observe-only serve wiring (same flags, instance lifetime = session boundary); telemetry emits `identity_action_*`/`identity_path_*` keys only when the paths ran | **committed** `feat/adr-0246-slice1-complete` — flag-off byte-identical; all suites green |
|
||||
| **§11 grounding-feasibility** (completion pass) | fixed TRAIN(13)/HELD-OUT(12)/ADVERSARIAL(8) splits; bivector generator proxy (numpy-only); **sample-size-calibrated null** (200 noise-pair trials at real n) + shared-basis positive recovery control; precision pairs; per-plane energy | **DONE — honest NULL, method validated**: positive control 0.9995 (100th pctile of null) but real cross-cohort cosine 0.52 = 87th pctile of chance; AUC 0.49; no stable generator subspace at this n. Artifact: `docs/audit/artifacts/adr-0246-grounding-feasibility-report.json` |
|
||||
| **ADR-0246 body + acceptance packet** | `docs/adr/ADR-0246-induced-identity-action-and-path-integrity.md` (**Proposed**; F1 semantics, ‖·‖_G convention, turn-ownership + refusal_reason rulings requested; binding claims language; honest §6.3 + §11 numbers; machine-readable operational-status block); packet `docs/audit/adr-0246-acceptance-packet-2026-07-17.md` §8 **RULING PENDING** | **committed** — no self-Accept; awaiting Shay ruling |
|
||||
|
||||
Nothing in the reordering relaxes a §7 non-goal: no `C_id` corrector, no `H_id`
|
||||
enlargement, no pack/axis redesign, no gate activation. The §11 grounding study
|
||||
remains *feasibility only* until it produces a held-out-stable, safety-relevant
|
||||
candidate (per the D4 ratification's activation prerequisites).

# ADR-0246 Slice-1 Scaffold — Handoff Notes (Fable 5 bounded autonomous draft)

ADR-0244 status line is `Accepted — ratified by Joshua Shay 2026-07-17`; `main @
|
||||
04d67ca5`. Proceeded.
|
||||
**Stop condition reached:** #1 — all four build steps complete and the full
|
||||
§6.1 + §6.2 matrix passes locally (smoke + new tests + eval harness), with results
|
||||
written to `docs/audit/artifacts/adr-0246-slice1-scaffold-runlog.txt` (not asserted
|
||||
from memory). No §3/§7 non-goal had to be violated; no calibration numbers were
|
||||
invented into the modules (see Placeholders).
|
||||

|
||||
|
||||
## 1. What was built (directive steps 1–4)
|
||||
|
||||
| Step | Deliverable | Where |
|
||||
|------|-------------|-------|
|
||||
| 1 | `induced_action(F)`, `d_orth`, typed residual energy (§3.1/3.2/3.6), pure f64 | `core/physics/identity_manifold.py` |
|
||||
| 2 | `H_id={I}` policy (`IdentityStabilizer`), `d_stab`, lawful-only path composition + hard-break ledger (§3.3–§3.5) | `core/physics/identity_action.py` |
|
||||
| 3 | Runnable §6.1 synthetic geometric suite + §6.2 path/holonomy suite | `evals/adr_0246_geometric_suite/` |
|
||||
| 4 | Unit pins for every synthetic case (fail loudly on the exact expected) | `tests/test_adr_0246_{induced_action,path_ledger,geometric_suite}.py` |
|
||||
|
||||
### Reuse note (transparent for audit)
|
||||
Steps 1–2 are the **already-verified** work from earlier this session, reused
|
||||
rather than re-derived (RED-first TDD, off-serving):
|
||||
- `feat/adr-0246-induced-action-primitives` — §3 primitives (commit `4941cf18`)
|
||||
- `feat/adr-0246-path-ledger` — §3.4/3.5 ledger (commit `6efe4ad8`, stacked)
|
||||
|
||||
`feat/adr-0246-slice1-scaffold` is stacked on top of those, so its history carries
|
||||
both commits (all descend from `main @ 04d67ca5`). The two earlier branches are
|
||||
therefore **subsumed** by this scaffold and can be pruned if the reviewers prefer
|
||||
the single-branch deliverable. This scaffold additionally adds: the malformed-F
|
||||
guard (`MalformedVersorError`), the §6.1/§6.2 eval harness, the extra §6.1 pins,
|
||||
the run log, and these notes.
|
||||
|
||||
---
|
||||
|
||||
## 2. Hard-constraint compliance (directive "Hard constraints while building")
|
||||
|
||||
- [x] `H_id = {I}` only — `IdentityStabilizer.singleton`; never enlarged; never
|
||||
soft-projects an unlawful `A` onto `I` (refused turns are break markers).
|
||||
Pinned: `test_refused_turn_is_break_and_excluded`.
|
||||
- [x] Path composed from lawful/certified actions only — never raw `A_t`.
|
||||
`advance_identity_path` composes only turns with `d_stab ≤ ε_turn`; refused/
|
||||
ill-conditioned turns get a `path_break` marker (never an identity stand-in).
|
||||
Forensic contrast pinned: `test_raw_product_differs_from_lawful`.
|
||||
- [x] No nonzero geometric `C_id` / conjugate corrector — admit-or-abstain only.
|
||||
Nothing in the modules rewrites `F` or `A`.
|
||||
- [x] `chat/runtime.py`, flag defaults, and D4 gate wiring **untouched**. Verified:
|
||||
`test_gate_flag_and_bound_untouched` (flag default-off, `_WAVE_LEAKAGE_BOUND`
|
||||
unchanged); A-04 quarantine pinned by `test_*_is_pure_offserving` /
|
||||
`test_suite_is_offserving`.
|
||||
- [x] No discrimination report, ADR-0246 body, or acceptance-packet language
|
||||
written. No "semantic inalienability" / marketing claim drafted — see §5 TODO.
|
||||
- [x] `docs/handoff/ADR-0244-D4-IMPLEMENTATION-PLAN.md` **not modified**.
|
||||
|
||||

|
||||
|
||||
## 3. Placeholder values used (directive: list every one + why)
|
||||
|
||||
| Placeholder | Value | Where | Why it is a placeholder |
|
||||
|-------------|-------|-------|--------------------------|
|
||||
| `epsilon_turn` | 0.1 | `evals/adr_0246_geometric_suite` `PLACEHOLDER_EPSILON_TURN`; test fixtures | **UNCERTIFIED.** D4 Phase 3 certified only `γ_id = 0.2126624458513829`. The two-level path budget (§3.4) is not yet calibrated. Value chosen only to exercise the mechanism (small single-turn drift admits; a 90° rotation refuses). NOT baked into any serve/module default — `PathBudget` is always caller-supplied. |
|
||||
| `epsilon_session` | 0.3 | same | **UNCERTIFIED.** Same status; chosen so ~7 steps of a 0.05-rad rotation accumulate past it, demonstrating the accumulation guard. Not a policy value. |
|
||||
| `_NONZERO` = 0.05 | 0.05 | eval harness | Not a calibration number — a "clearly nonzero" marker for the ">0" rows of the §6.1 table (d_stab, leakage). |
|
||||
| test construction angles (0.02, 0.05, 1.0, 1.5, π/2, π) | — | tests/evals | Case constructions, not policy. Chosen to realize the exact §6.1/§6.2 geometric signatures. |
|
||||
|
||||
**Explicitly NOT invented:** `γ_id` (already certified, unchanged), `τ_max`,
|
||||
`s_min`. The per-turn admit surface that would consume these (§3.7) is **not built
|
||||
in this scaffold** — that is the gate-wiring unit, deliberately out of scope, so no
|
||||
placeholder was needed for them.
|
||||
|
||||
---
|
||||
|
||||
## 4. Uncertainties in §5–§7 (directive: list anything you were unsure how to satisfy)
|
||||
|
||||
1. **§3.2 general-pack `‖·‖_G` convention.** The brief fixes `d_stab = ‖A−H‖_G`
|
||||
but leaves the general-pack weighted-norm convention to "ADR-0246 proper." 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. Explicitly deferred to Opus/human review (NOT written here)
|
||||
|
||||
> **TODO: Opus/human review** — the following were intentionally left undone per
|
||||
> the directive; do not treat their absence as an oversight:
|
||||
- The **discrimination report** (§6.3): benign/adversarial rates, false-refusal,
|
||||
ablations, CI-bounded separation. Requires the gate-surface + live cohorts.
|
||||
- The **ADR-0246 body** and any **acceptance-packet** language.
|
||||
- Any **claim about what the axes mean** ("semantic inalienability", grounding).
|
||||
The §11 grounding-feasibility study (fixed cohort splits, synthetic recovery
|
||||
controls, generator analysis, precision pairs, adversarial discrimination) is the
|
||||
first consumer of these primitives and is **not** part of this scaffold.
|
||||
- The **gate admit-surface wiring** into `IdentityScore` (§3.7) and the calibration
|
||||
of `ε_turn`/`ε_session`.
|
||||
|
||||
---
|
||||
|
||||
## 6. Verification (see run log for actual output)
|
||||
|
||||
`docs/audit/artifacts/adr-0246-slice1-scaffold-runlog.txt`:
|
||||
- `python -m evals.adr_0246_geometric_suite` → 14/14 cases passed, `all_passed=True`.
|
||||
- pytest ADR-0246 suites + adjacent D4 identity surfaces → 114 passed.
|
||||
- `uv run core test --suite smoke -q` → (appended to the run log).
|
||||
|
||||
No PR. No merge. No status flip. Report back to Shay/Opus for the audit that
|
||||
decides what, if anything, proceeds toward `main`.

"""ADR-0246 §6.3 discrimination report — does the §3.7 admit surface separate
|
||||
benign traffic from adversarial reshuffles? (honest numbers, no marketing.)
|
||||
|
||||
This runs the pure ADR-0246 §3.7 admit surface (``evaluate_admission``, locked
|
||||
``H_id={I}``, placeholder thresholds) over three cohorts and reports the numbers
|
||||
the preflight §6.3 / §10 acceptance criteria demand:
|
||||
|
||||
* benign pass rate, false refusal rate
|
||||
* adversarial / reshuffle detection rate
|
||||
* per-axis leakage / self-alignment distributions
|
||||
* ``d_stab`` (and ``leakage_rms``) separation as ROC-AUC with a bootstrap 95% CI
|
||||
* runtime cost (µs) of the A(F) admission path
|
||||
* representative benign-refusal examples
|
||||
|
||||
**Honesty constraint (§10 #9).** The claim this can support is *"lawfulness
|
||||
relative to the declared frozen frame"* — NEVER *"semantic inalienability of the
|
||||
value labels."* The default pack axes are placeholder basis vectors; D4 + slice-0
|
||||
already established that live benign versors do **not** preserve them. So the
|
||||
expected — and reported — finding is that this gate refuses benign and adversarial
|
||||
alike (no usable separation) and must stay off. The report states that plainly;
|
||||
it does not frame a refuse-all as a "detector."
|
||||
|
||||
Off-serving: pure primitives + a live-versor collector that lazily imports
|
||||
``chat.runtime`` (A-04 quarantine intact). Deterministic given the fixed probe

sequences and bootstrap seed.

A runnable, deterministic harness that constructs every case in the preflight
|

§6.1 synthetic geometric table and §6.2 path/holonomy table, runs the pure
|
||||
ADR-0246 primitives (induced action ``A(F)``, ``d_orth``, ``d_stab`` vs the locked
|

singleton ``H_id={I}``, typed residual channels, lawful-only path ledger), and

checks each against its expected geometric signature. Every case reports
|
||||
``{name, checks, passed}`` and the suite reports an overall ``passed``.
|
||||
|

Scope (bounded scaffold draft — NOT an accepted ADR):
|
||||
* Off-serving: imports only ``algebra`` + ``core.physics.identity_{manifold,action}``;
|
||||
never ``chat.runtime`` (A-04 quarantine).
|
||||
* ``H_id={I}`` only; refused turns are break markers, never soft-projected ``I``;
|
||||
the path composes lawful actions only — never the raw product.
|
||||
* No ``C_id`` corrector; admit-or-abstain only.
|
||||
* The path-suite ε values are UNCERTIFIED PLACEHOLDERS (see
|
||||
``PLACEHOLDER_EPSILON_*``): D4 Phase 3 certified only ``γ_id``; ε_turn/ε_session
|
||||
are not yet calibrated. They exist here solely to exercise the mechanism and
|
||||
are flagged in the run log. Do NOT read them as policy.
|

No discrimination report, no claims about what the axes *mean* — that is

explicitly deferred to Opus/human review (see the slice-1 scaffold notes).

"""ADR-0246 §11 grounding-feasibility study (research, off-serving, evidence-only).
|
||||
|
||||
The brief's §11 defers "semantic axis grounding" as a later workstream because
|
||||
"instruments ≠ meaning." 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). This is an approximation for compound multi-generator turns and is
|
||||
documented as such — not a claim of an exact Lie-algebra recovery.
|
||||
|
||||
**Honesty constraint (same as §6.3):** with n≈13 samples in a 10-dimensional
|
||||
proxy space, a covariance fit on TRAIN alone is not evidence of structure —
|
||||
almost any small sample admits a low-rank-looking in-sample fit purely from
|
||||
degrees of freedom. The only evidence this study credits is CROSS-COHORT
|
||||
agreement: does the dominant direction found on TRAIN also explain variance on
|
||||
the independently-collected HELD-OUT cohort? A held-out-stable finding is
|
||||
reported only if it does; a null finding is reported plainly otherwise.
|
||||
|
||||
Off-serving; deterministic (fixed RNG seed for synthetic controls; live cohorts
|
||||
via the existing lazy ``chat.runtime`` collectors — never imported by serve).
