Executes the explicit in-session 'Ratify' ruling on the D10 acceptance packet (docs/audit/adr-0241-0242-acceptance-packet-2026-07-15.md §8 ruling record added): - ADR-0241 status: Proposed → Accepted (P7 demote-with-proof accepted as honest per the #19 precedent; T1/T2 serve-boundary reconciliation ratified; chiral sign-gate enforced on the accepted state via PR #41). - ADR-0242 status: Proposed → Accepted (memo fidelity slice closed with no new defects; V5 anyons remain claim-quarantined/not built; V2 production promotion stays benchmark-gated). - CRDT determinism ruling (PR #42) ratified: single-writer bit-exact now; CRDT behind an explicit multi-writer gate. - Checklist header, fidelity-ledger §12 status, and living summary §12 updated to the ratified state. Post-Accept work remains tracked (W5 backlog + packet §7 carry items); none are conditions of this Accept.

ADR-0242: Deterministic Fibonacci Operators and Evidence-Gated Optimization
Status: Accepted — ratified by Joshua Shay 2026-07-15 (explicit "Ratify" ruling on the D10 acceptance packet, docs/audit/adr-0241-0242-acceptance-packet-2026-07-15.md; memo fidelity slice closed §7, no new defects). V1 cert + V3 packing + V2 research helpers + V4 word schedule + sensorium feed landed; V5 anyons NOT built (claim-quarantined per the packet); V2 production promotion stays benchmark-gated per §3.2.

Context
ADR-0241 establishes continuous wave-field \psi. Optimization, scheduling, and multi-scale allocation still need deterministic, reconstructible operators that earn their place under CORE’s evidence discipline — not sacred-geometry dogma.
Drive ADR-0242 defines five Fibonacci vectors. An earlier in-repo draft understated that thesis as packing + section search only. This document restores the full scope and records honest landing status.
Sovereignty invariant (absolute)
Fibonacci operators may optimize search parameters, set observation scale, or schedule background checks; they must NEVER dictate proposition truth, safety policy, identity, or authorize autonomous COHERENT promotion.
Active reasoning, vault standing, and serve remain governed by versor closure, CRDT exactness, and human-gated review.
Decision — five vectors
Vector 1 — Bounded Fibonacci-section search (production Phase 1) 🟢
Module: core/physics/fibonacci_search.py
BoundedUnimodalObjectivefibonacci_section_search(objective, func) -> FibonacciSearchCertificate | OptimizationFailure- Never returns a bare float
- Certificate is content-addressed (
cert_id= SHA-256 of ordered trace + ids) - Fail-closed: nonfinite, bounds, unimodality multi-extrema →
OptimizationFailure - κ seam:
propose_kappa_from_search/goldtether.propose_kappa_line_search- success → proposed κ = minimizer (telemetry; no auto state mutation)
- failure → baseline κ = 1.0
Vector 2 — Multi-scale temporal basis (research helpers) 🟢 research / 🟡 production
Drive:
[ E_n(t) = E_n(t_0),\exp\bigl(-(t-t_0)/(F_n\tau_0)\bigr) ]
wave_energy_boundary.fibonacci_tau_schedule/recency_band_index(constants table)multi_scale_energy.py:multi_scale_energy_vector,dyadic_tau_schedule,comparative_residual_separation
Not production default insideFieldEnergyOperator. Flip requires comparative benchmark + Joshua gate.
Vector 3 — Golden-Angle mode allocator 🟢
Module: core/physics/atlas_packing.py
- Golden-Angle polar lift via
embed_point→ null 32-vectors - Fail-closed if pairwise CGA null-point
d < d_{\min}(default 0.12) - Honest metric: Euclidean null-cone readout, not full
H^2geodesic - Reconstruction-over-storage:
ALLOCATOR_VERSION = golden_angle_v1+allocator_layout_descriptor - Not holographic seals (null points ≠ closed unit versors)
Vector 4 — Fibonacci-word observability choreography 🟢
Module: core/physics/fibonacci_word_schedule.py
Drive: W_0=B, W_1=A, W_{n+1}=W_n W_{n-1} for telemetry / sealed-holdout sampling.
Outside cognitive truth path — pure schedule only; no vault/field mutation.
Vector 5 — Topological anyon / braid holonomy 🟢 quarantine box
Package: algebra/topological_reasoning/ (README + FUSION_RULE stub).
Production AST pin: chat/, core/physics/, generate/, vault/, teaching/ must not import it.
No fusion/braid logic until proofs + human Accept.
Phase order (Drive §5)
| Phase | Vector | Status |
|---|---|---|
| 1 | V1 search + κ cert gate | 🟢 |
| 2 | V2 multi-scale energy study | 🟢 helpers; 🟡 not production default |
| 3 | V3 packing | 🟢 |
| 4 | V4 word scheduler | 🟢 |
| 5 | V5 anyons | 🟢 quarantine only (no logic) |
Serve quarantine (A-04)
fibonacci_search, atlas_packing, wave_energy_boundary must not be imported from chat/runtime.py (AST pin in tests/test_third_door_cohesion.py).
Consequences
Benefits
- Evidence-gated optimizers (typed cert/failure)
- Deterministic packing without
core_hanode IDs - Clear multi-vector roadmap without dogma
Trade-offs
- Sample-based unimodality (not global oracle)
- Packing separation not full hyperbolic geodesic
- V2 production promotion deferred pending benchmarks

Acceptance path
Joshua review may Accept after Phase 1 (V1+V3) is verified in merge.
V2/V4/V5 need not block Phase 1 Accept if status rows remain honest RESEARCH/staged.
Agents must not self-Accept.
