# ADR-0244 — D4 Acceptance Packet for Joshua

**Arc:** ADR-0244 Wave-Field Identity Manifold & Inalienable Geometric Alignment (D4 Phases 0–6), built on the ADR-0243 lifecycle + the ADR-0245 mechanical-sympathy foundation.
**Evidence base:** `feat/adr-0244-d4 @ 8ef80daa` (Phases 0–5 pushed direct-to-`main` per your sole-worker authorization; Phase 6 = this packet + the ADR-0245 packet).
**Status of ADR-0244:** **Accepted (with a ratified live-activation limitation)** — ratified by Joshua Shay on 2026-07-17. Accepted as an implemented mechanism; `identity_wave_gate` stays **default-off** and live activation is **NOT authorized** pending ADR-0246. §8 is RATIFIED; see §5 for the caveat that shaped the ruling.

## 1. Evidence summary (what is proven, and how)

| ADR § | Claim | Built as | Evidence | Verdict |
|-------|-------|----------|----------|---------|

| §2.2 | Fail-closed spectral-leakage gate + `C_id` + `IdentityGateRefusal`; `boundary_ids` active | dual-mode `IdentityCheck.check(..., wave_field=, violated_boundary_ids=)`, `_validate_wave_field`, admit-or-abstain `conjugate_correct`, wave telemetry; flag-gated wiring in `chat/runtime.py` | `test_adr_0244_identity_gate_wave.py` (16) + `_runtime.py` (3) + `_eval.py` (6): fail-closed on malformed ψ; boundary intersection; flag-off byte-identity; ablation separates geometric attacks 6-vs-0 over legacy | **Built + validated; NOT live (D-2, see §5)** |
| §2.3 | `Q_top` topological-charge conservation at egress | Proven **vacuous** on the versor manifold; retired from egress | `evals/adr_0244_qtop_vacuity` + `test_adr_0244_qtop_vacuity.py`: `Q_top ≡ 0` on every rotor/boost; aligned + adversarial both read 0 | **Retired (D-3), kept as diagnostic** |
| §2.4 | Bracketed-local Fibonacci search calibrates `γ_id` | `evals/adr_0244_gamma_calibration/` — certified `γ* = 0.2126624458513829` (cert `0079b5f2…`), pinned `identity._WAVE_LEAKAGE_BOUND` | `test_adr_0244_gamma_calibration.py` (9): certificate reproducible/deterministic; separates the geometric attack set | **Machinery supported; live flip NOT authorized (D-2)** |
| §2.5 | Governed f64→f32 serving-boundary cast | `serving_cast(...) → ServingState` in `cognitive_lifecycle.py` | `test_adr_0244_serving_cast.py` (10): casts only certified/admitted/digest-matched; precision-checked; f64 stays source of truth | **Supported** |

| §2.8 | `eigh` memoization | `_cached_eigh` (D2) | `test_adr_0244_mechanical_sympathy.py` | **Supported** |
| §2.9 | Low-discrepancy mode allocator / order-independence | **Proven** (not wired): recall = Gram lstsq onto span → permutation-invariant to ~1e-15; allocator ordinal-reconstructible | `test_adr_0244_mode_order_independence.py` (3) | **Supported, restated (D-4)** |
| §2.10 | Quasi-periodic Fibonacci-word scheduler reduces phase-locking | audit-confirm the load-bearing claim | `test_adr_0244_scheduler_quasiperiodicity.py` (32): golden-ratio density, no `BB`/`AAA`, aperiodicity | **Supported** |

## 2. Deviations submitted for ruling (implementation vs. ADR prose)

- **D-1 — operator-preservation reframe (the core-mechanism correction; ratified 2026-07-17).** §2.1/§2.2's literal "project ψ_traj onto the grade-1 value subspace" is **vacuous** on the real runtime object: `final_state.F` is a **versor (even-grade operator, grades 0/2/4, zero grade-1)**, so `P_id(F) = 0` identically — it would flag every trajectory. Resolution: measure whether the versor *preserves* the value subspace via its action on the axes `F aᵢ F̃` — subspace leakage (tilt toward e4/e5) + signed self-alignment (in-subspace inversion). Both verified necessary and non-redundant. Governance annotation item 12 + §4a. **You ratified this reframe on 2026-07-17.**
- **D-2 — the identity gate is validated scaffolding, NOT a live gate (the honest headline).** See §5. `identity_wave_gate` stays **OFF**.
- **D-3 — `Q_top` dropped from the egress condition.** Proven vacuous (central `I₅` in odd Cl(4,1); the #19 pseudoscalar failure mode). Egress is leakage-based; `Q_top` kept only as a diagnostic. The §2.3 conservation claim is scoped to versors.
- **D-4 — §2.9 proven, not wired.** Recall is already insertion-order-independent by construction (Gram projection onto a span). Wiring the allocator into the durable content-seal path would be a category mismatch (that path seals content ψ, not packing positions), so the honest deliverable is the proof.

## 3. Deferred items (explicitly NOT completion blockers, but scoped)

- **The LIVE identity gate → ADR-0246.** Flipping `identity_wave_gate` on is deferred because the current engine gives the identity subspace no dynamical anchoring (§5). The induced-identity-action programme (ADR-0246 preflight brief, already merged) is where identity becomes dynamically load-bearing so the gate separates live traffic.
- **Real identity eigenmodes.** The shipped value axes (`truthfulness=e1`, `coherence=e2`, `reverence=e3`) are nominal basis vectors, not eigenmodes fit from an identity-preserving-vs-violating trace corpus. Fitting them is future work (a data/encoder concern, not a D4 mechanism gap).
- **Bounded corrective `C_id` displacement.** v1 is admit-or-abstain (zero displacement — the conservative bound). A bounded geometric corrective step is a future enhancement.

## 5. Requested action — and the one caveat that shapes it

**Rule on the ADR-0244 arc.** Every §-mechanism is built, proven, or audited (§1). The arc is honest and complete **as scaffolding**. There is exactly one thing you must weigh:

> **The identity wave-gate is BUILT and VALIDATED but is NOT wired live** (`identity_wave_gate = False`), and D4 does **not** flip it on. Phase 3 measured the reason directly: real benign turns do **not** preserve `span(e1,e2,e3)` — their leakage spans 0.14–0.81, self-alignment swings negative, and the best achievable balanced error separating benign from attacks is **0.346**. Flipping the flag would mass-refuse benign traffic. Root cause: the pack value axes are *nominal basis vectors, not dynamically-preserved eigenmodes* — the field evolution gives identity no dynamical anchoring. Making identity dynamically load-bearing is the **ADR-0246** programme.

So the ruling is on the ADR **as a specification and a validated mechanism**, with the explicit, recorded understanding that the live gate awaits ADR-0246. If you rule **Ratify**, the follow-up one-line governance commit flips `**Status**: Proposed → **Accepted** — ratified by Joshua Shay <date>` and records the ruling in §8. The four deviations (D-1…D-4) and the "validated-but-off" scope are submitted for acceptance as recommended. **I have not flipped the status; it awaits your explicit word.**

## 8. RULING RECORD

**RATIFIED — Joshua Shay, 2026-07-17.** ADR-0244 accepted **as an implemented mechanism** — the operator-preservation manifold, fail-closed gate capability, `γ_id` calibration record, telemetry, and lifecycle contracts — **not** as authorization to enable live identity enforcement. **The Phase-3 calibration explicitly did NOT authorize a production flip:** it measured that benign traffic is not separable at the frozen nominal frame (best balanced error 0.346). `identity_wave_gate` remains **default-off** and live activation is **NOT authorized**, blocked pending a **separately ratified ADR-0246** (induced identity action, lawful stabilizer `H_id`, path integrity, semantic-frame discrimination) **plus** renewed discrimination evidence, an acceptable benign refusal rate, and explicit human ratification. Status flipped `Proposed → Accepted` on 2026-07-17 with provenance inline (+ machine-readable `identity_wave_gate:` ledger block in the ADR header). "Accepted" here means implemented, **not** safe-to-activate.
