+# ADR-0242: Hyperbolic Atlas Golden-Angle Packing and Fibonacci Search
+
+**Status**: Proposed — packing + Fibonacci search green on branch; acceptance path: Joshua review + merge  
+**Date**: 2026-07-14  
+**Deciders**: Joshua Shay + multi-model R&D (Gemini implementation pass)  
+**Traceability**: PR #37, parent ADR-0241 / cohesion master plan  
+**Related**: ADR-0003, ADR-0238, ADR-0241, `docs/analysis/core_cohesion_master_plan.md`, `docs/briefs/ADR-0242-atlas-packing-and-fibonacci-brief.md`  
+**Canonical path**: `docs/adr/`
+
+---
+
+## Context
+
+ADR-0241 established `WaveManifold` and `HolographicVaultStore`. Entity cohesion still needed:
+
+1. **Uniform resonant-mode packing** without resurrecting pointwise `core_ha` node IDs or Poincaré as runtime memory truth (ADR-0003).
+2. **Fixed-budget unimodal scalar search** for construction/calibration (e.g. GoldTether κ brackets) without scipy-as-truth or stochastic optimizers.
+
+## Decision
+
+### 1. Golden-Angle packing (`core/physics/atlas_packing.py`)
+
+For \(k = 0 \ldots n-1\):
+
+\[
+\theta_k = 2\pi k / \varphi,\qquad r_k = \tanh(\alpha\sqrt{k})
+\]
+
+Lift \((r\cos\theta, r\sin\theta, 0)\) via `algebra.cga.embed_point` to Cl(4,1) **null points**.
+
+**Separation pin:** CGA null-point distance from `cga_inner` contract \(\langle P,Q\rangle = -d^2/2\):
+
+\[
+d = \sqrt{-2\langle P,Q\rangle}
+\]
+
+Fail-closed (`AtlasPackingError`) if any pair has \(d < d_{\min}\) (default \(0.12\)).
+
+**Honest scope:** this \(d\) is the Euclidean distance of the embedded \(\mathbb{R}^3\) points (null-cone isometric readout), not a full hyperbolic \(H^2\) geodesic solver. Sufficient for the cohesion packing density gate.
+
+**No attribute leaks:** returned modes are pure `float64` 32-vectors. No stored θ/r.
+
+**Not holographic seals:** packed null points are session mode-registry geometry; `HolographicVaultStore.seal_mode` still requires closed unit versors.
+
+### 2. Fibonacci section search (`core/physics/fibonacci_search.py`)
+
+- `BoundedUnimodalObjective(lower, upper, evaluation_budget, objective_id, objective_version)`
+- `fibonacci_section_search(objective, func) -> SearchTrace`
+- Exactly `evaluation_budget` evaluations
+- Fail-closed on nonfinite, bounds violation, sampled unimodality violation
+- Certificate carries budget, ids, bounds, best value, n_evals
+
+### 3. Serve quarantine (A-04)
+
+Neither module may be imported from `chat/runtime.py`. Pinned in `tests/test_third_door_cohesion.py`.
+
+## Consequences
+
+### Benefits
+
+- Deterministic atlas packing for standing-wave mode placement
+- Algebra-native fixed-budget scalar search for κ / residual brackets
+- Continues `core_ha` deprecation (no node IDs / Poincaré runtime store)
+
+### Trade-offs
+
+- Separation is CGA null-point Euclidean distance, not full hyperbolic geodesic
+- Unimodality check is sample-based (only evaluated points), not a global oracle
+- Packing modes are null points, not unit versors — durable vault seal path remains separate
+
+## Validation
+
+- `tests/test_adr_0242_atlas_packing.py`
+- `tests/test_adr_0242_fibonacci.py`
+- `tests/test_third_door_cohesion.py` (serve quarantine + κ integration)

+# CORE AGI/ASI Unified Wave-Field Substrate and Entity Cohesion Master Plan
+
+**Status**: Proposed (acceptance path: green verification suite + Joshua review)  
+**Date**: 2026-07-14  
+**Authors**: Multi-model R&D + Joshua Shay  
+**Traceability**: Notion R&D (Engineering Reference Vault Interconnection: `core_ha` Patterns)  
+**Related**: ADR-0003, ADR-0238, ADR-0239, ADR-0240, ADR-0241, ADR-0242, `core-rs/src/vault.rs`

+
+**Doctrine note (AGENTS.md):** R-01 “dual-correction fallback to nearest exact versor” must **not** be implemented as hot-path drift repair. Unitary residual breaches **fail-closed**. Any close/unitize is allowed only at owned construction / admit boundaries (`wave_manifold` exp construction, holographic admit, biography construction). Silent nearest-versor repair in `field/`, `generate/`, or vault hot paths is forbidden.
+
+---
+## 1. Executive Summary & The Unified Substrate Cohesion Thesis
+
+The Continuous Orthogonal Resonance Engine (CORE) represents a paradigm shift where cognitive states are represented as coordinate-free fields of meaning over a manifold rather than static points in a flat embedding space. To realize this vision with complete mathematical and system-level cohesion, this master plan details the unification of the **Hyperbolic Atlas** into the **$Cl(4,1)$ Conformal Wave-Field ($\psi$)** substrate.
+
+By compiling all multi-modal sensory inputs (text, audio, vision, motor) down to the same wave-field substrate, we establish a **single, cohesive, living-system entity**. This document resolves the remaining engineering gaps, provides end-to-end topological trace diagrams, defines a rigorous entity-level invariants checklist, outlines a unified test suite, and establishes a safe migration and deprecation plan for the legacy `core_ha` codebase.
+
+---
+
+## 2. End-to-End Invariant Trace Diagrams
+
+The cognitive lifecycle of the living entity is mapped across two primary closed-loop cycles, ensuring that every transition is mathematically bound and audit-logged.
+
+### Trace A: Sensory Ingestion and Memory Cycle (Information Flow)
+

+
+---
+
+## 3. Entity-Level Invariants Checklist (AGI/ASI Living-System Audit)
+
+To treat the cognitive manifold as a cohesive, single living system, we enforce five **Entity-Level Invariants**. Any transaction, self-authorship loop, or optimization that violates these checks is refused at the hardware boundary.
+
+- [ ] **I-01: Identity Holonomy Persistence**: The biography holonomy blade ($\mathcal{H}_{\t\text{bio}} \in Cl(4,1)$) must remain structurally closed ($	\text{versor_condition} < 10^{-6}$) and invariant across system reboots, reconstructed purely from the canonical, content-addressed ledger.  
+- [ ] **I-02: Substrate Round-Trip Replay-Determinism**: A wave-field $\psi_1$ compiled into a CRDT-delta, sharded to the vault, and recalled via the teaching-chain must reconstruct the identical, bit-pattern wave-field $\psi_2$ under the exact boundary conditions: $$|\psi_2 - \psi_1|_F < 10^{-12}$$  
+- [ ] **I-03: No Self-Mutation in Self-Authorship**: Speculative self-authorship loops or miners (`core/physics/self_authorship.py`) are strictly prohibited from directly modifying the active manifold or writing `COHERENT` vault states. Every self-authored change must be written as a `SPECULATIVE` proposal, routed through the one-mutation-path, and require explicit human-gated ratification.  
+- [ ] **I-04: Non-Stochastic Multimodal Resonance**: Cross-modal pattern matching (aligning audio to text, or vision to motor) must be purely algebraic, mediated through the metric-exact phase correlation ($\langle \psi_A \widetilde{\psi}_B + \psi_B \widetilde{\psi}_A \rangle_0$) in $Cl(4,1)$ CGA. Traditional stochastic nearest-neighbor, cosine similarity, or probabilistic search models are forbidden.  
+- [ ] **I-05: Unitary Propagator Amplitude Conservation**: Every wave-field transition $\psi \to R \psi$ must preserve the wave's normalized amplitude density. The GoldTether coherence residual must act as the absolute boundary guard: $$R_{	\text{GoldTether}} = \\sup_{X \in M} \left| \psi(X, t) \widetilde{\psi}(X, t) - 1 ight|_F < 10^{-6}$$
+
+---
+
+## 4. Falsifiability & Benchmark Framework (Vector-Specific Tests)
+
+To prevent R&D from collapsing into descriptive architecture prose, every Fibonacci and wave-field operator must be validated against concrete comparison classes and workloads.
+
+### 4.1 Benchmark Metrics and Objectives
+
+- **Fidelity Score**: Measures the final interval/bracket width under a fixed budget of $N$ evaluations.  
+- **Surprise Separation**: Measures the distance between the surprise energy of in-distribution inputs versus out-of-distribution (OOD) pathological inputs.  
+- **Insertion Cost**: CPU cycles and memory allocations required to register a new mode centroid in the Atlas.  
+- **Drift Under float32**: The accumulation of numerical rounding errors over a trajectory of $T = 1000$ steps under single-precision floating-point arithmetic.
+
+### 4.2 Benchmark Execution Plan and Failure Thresholds
+
+1. **Synthetic Unimodal Objective**: A convex quadratic $f(x) = (x - x_0)^2$ and a highly non-unimodal function (e.g., Rastrigin) are evaluated.  
+2. **Replayable GoldTether/Procrustes Snapshots**: Extract actual coordinate traces from previous runs on `main` and run the benchmarks under identical evaluation budgets.  
+3. **Failure Thresholds**:  
+   - Any nonfinite value (`NaN`, `inf`) or bounds-violation instantly raises `OptimizationFailure`.  
+   - If the stable, coordinate-sorted trace detects multiple local extrema, the validator flags a `unimodality_violation_multiple_extrema_detected` and rejects the run.  
+   - If the Golden-Angle allocator results in a pairwise geodesic separation of less than $d_{	\text{min}} = 0.12$ on the horosphere, it is rejected.
+
+---
+
+## 5. Hardware and Rust/CGA Bindings Depth
+
+To maintain "Mechanical Sympathy" and avoid sub-optimal performance in Python, the wave-field and Fibonacci operations are compiled directly into the Rust hot-path (`core-rs/src/`).

+
+- **`cl41::wedge`**: High-performance Rust implementation of the exterior product. This is utilized for signature-aware PCA blade construction and boundary calculations.  
+- **`diffusion.rs::expm`**: A custom, unitarity-exact matrix exponential solver implemented in Rust. It computes $R = \exp(B \Delta t)$ with zero floating-point accumulation drift by enforcing the rotor manifold constraint on intermediate series sums.  
+- **`versor_unit_residual`**: A highly optimized, SIMD-parallelized C-level FFI binding that evaluates the GoldTether unit-norm supremum across the entire wave manifold in sub-millisecond execution cycles, utilizing the Apple Silicon Unified Memory Architecture (UMA) lanes.

+## 7. Migration Safety Net & Pre-Deprecation Grep Audit
+
+To ensure the removal of `core_ha` does not introduce dangling references or silent compiler breakages, a **Pre-Deprecation Safety Net** is enforced:
+
+### Step 1: Pre-Deprecation Grep Audit
+
+Before deleting the legacy `core_ha` codebase, run the following automated workspace scans to identify and document every file-level import and reference:
+
+# Locate all Python imports of core_ha or its child modules
+
+grep -rn "import core_ha" .
+
+grep -rn "from core_ha" .
+
+# Locate all references to hyperbolic_primitives or poincare coordinates
+
+grep -rn "hyperbolic_primitives" .
+
+grep -rn "poincare" .
+
+### Step 2: Migration Branching & Rollback Tagging
+
+1. Create a secure pre-migration git tag on the current repository head:  
+     
+   git tag -a v1.99-pre-wave-unification -m "Stable baseline before core_ha deprecation and wave-field migration"  
+     
+   git push origin v1.99-pre-wave-unification  
+     
+2. Checkout a dedicated migration branch `feat/wave-unification-and-ha-deprecation` to perform the changes.
+
+---
+
+## 8. Phase 0 Pre-Implementation Audit Checklist
+
+Every developer agent or engineer must verify the following five pre-requisites before executing the migration code:
+
+- [ ] **A-01: Branch Parity Check**: Compare `r&d/generalized-agent` and all `feat/third-door-*` branches against `main` to identify and resolve any conflicting bivector or dynamic manifold modifications.  
+- [ ] **A-02: Local File Integrity**: Execute a full `get_file_content` scan on `core/physics/dynamic_manifold.py` and `core/physics/surprise.py` to confirm they contain the latest, uncorrupted, and correctly imported WaveManifold bindings.  
+- [ ] **A-03: Dependency Verification**: Trace the imports in `tests/conftest.py` and `tests/invariants/` to ensure no active test suites contain hardcoded, non-CGA Euclidean projection assertions.  
+- [ ] **A-04: Serve-Path Containment**: Confirm that no new wave-field calculation or Fibonacci search operator is wired into the active serving path (`chat/runtime.py`). They must reside strictly inside the `evals/` and `calibration/` quarantine zones.
+
+---
+
+## 9. Risk Register Table
+
+The foreseeable architectural risks associated with this major wave-field and optimization unification are documented below, along with their respective mitigation protocols:
+
+| Risk ID | Foreseeable Architectural Risk | Impact | Mitigation Protocol |
+| :---- | :---- | :---- | :---- |
+| **R-01** | **Numerical Drift in Long Horizons**: Accumulation of rounding errors in `expm` bivector calculations during long-horizon spinor transports, breaking the unitary condition. | High | **Dual-Correction Fallback**: Embed strict `versor_unit_residual` and `chiral_charge` checks at every boundary. If drift exceeds $\epsilon = 10^{-6}$, trigger a dual-correction fallback to the nearest exact versor. |
+| **R-02** | **Performance Bottlenecks in Python**: Scalar integrals and matrix exponential calculation in Python introduce latency overhead in active contemplation loops. | Medium | **FFI Compilation**: Implement the `expm` kernels and multivector multiplications directly in the Rust `core-rs/src/lib.rs` and compiled FFI, leveraging the Apple Silicon UMA lanes. |
+| **R-03** | **Dangling Legacy References**: Legacy `core_ha` or pointwise coordinate references are missed during deprecation, causing runtime `ImportError` inside auxiliary evaluation suites. | Low | **Pre-Deprecation Grep & CI Gate**: Run the automated pre-deprecation grep audit step, run the migration test suite locally, and gate the final pull request on a clean CI build. |
+| **R-04** | **Overhead in Hot-Path Loops**: Cryptographic trace generation and domain-separated hashing introduce CPU cycle overhead during high-frequency search evaluations. | Low | **Gated Observability**: Limit trace generation strictly to the calibration and training-loop pipelines. Active execution and hot-paths must receive only the pre-ratified, frozen scalar values. |
+
+---
+
+## Appendix A: Pre-Deprecation Grep & Phase 0 Audit Checklists
+
+To guarantee that the removal of legacy codebase structures is completely safe and introduces no compilation or import breakages, we execute the following Phase 0 checklists and audits.
+
+### 1. Pre-Deprecation Grep Scan
+
+Run these scans across the local workspace to identify and document every file-level import or coordinate reference to the old Poincar models:  
+- Locate all Python imports of core_ha:  
+`grep -rn "import core_ha" .`  
+`grep -rn "from core_ha" .`  
+- Locate all Poincare/Hyperbolic coordinate references:  
+`grep -rn "hyperbolic_primitives" .`  
+`grep -rn "poincare" .`
+
+### 2. Phase 0 Pre-Implementation Checklist
+
+Every developer agent or engineer must verify the following five pre-requisites before executing the migration code:
+
+- **A-01: Branch Parity Check**: Compare `r&d/generalized-agent` and all `feat/third-door-*` branches against `main` to identify and resolve any conflicting bivector or dynamic manifold modifications.  
+- **A-02: Local File Integrity**: Execute a full `get_file_content` scan on `core/physics/dynamic_manifold.py` and `core/physics/surprise.py` to confirm they contain the latest, uncorrupted, and correctly imported WaveManifold bindings.  
+- **A-03: Dependency Verification**: Trace the imports in `tests/conftest.py` and `tests/invariants/` to ensure no active test suites contain hardcoded, non-CGA Euclidean projection assertions.  
+- **A-04: Serve-Path Containment**: Confirm that no new wave-field calculation or Fibonacci search operator is wired into the active serving path (`chat/runtime.py`). They must reside strictly inside the `evals/` and `calibration/` quarantine zones.
+
+---
+
+## Appendix B: Entity Living-System Invariants (AGI/ASI Cohesion Audit)
+
+To treat the cognitive manifold as a cohesive, single living-system entity, we enforce five **Entity-Level Invariants**. Any transaction, self-authorship loop, or optimization that violates these checks is refused at the hardware boundary:
+
+- **I-01: Identity Holonomy Persistence**: The biography holonomy blade ($\mathcal{H}_{\t\text{bio}} \in Cl(4,1)$) must remain structurally closed ($\text{versor\\_condition} < 10^{-6}$) and invariant across system reboots, reconstructed purely from the canonical, content-addressed ledger.  
+- **I-02: Substrate Round-Trip Replay-Determinism**: A wave-field $\psi_1$ compiled into a CRDT-delta, sharded to the vault, and recalled via the teaching-chain must reconstruct the identical, bit-pattern wave-field $\psi_2$ under the exact boundary conditions: $$\|\psi_2 - \psi_1\|_F < 10^{-12}$$  
+- **I-03: No Self-Mutation in Self-Authorship**: Speculative self-authorship loops or miners (`core/physics/self_authorship.py`) are strictly prohibited from directly modifying the active manifold or writing `COHERENT` vault states. Every self-authored change must be written as a `SPECULATIVE` proposal, routed through the one-mutation-path, and require explicit human-gated ratification.  
+- **I-04: Non-Stochastic Multimodal Resonance**: Cross-modal pattern matching (aligning audio to text, or vision to motor) must be purely algebraic, mediated through the metric-exact phase correlation ($\langle \psi_A \widetilde{\psi}_B + \psi_B \widetilde{\psi}_A \r\rangle_0$) in $Cl(4,1)$ CGA. Traditional stochastic nearest-neighbor, cosine similarity, or probabilistic search models are forbidden.  
+- **I-05: Unitary Propagator Amplitude Conservation**: Every wave-field transition $\psi \to R \psi$ must preserve the wave's normalized amplitude density. The GoldTether coherence residual must act as the absolute boundary guard: $$R_{\t\text{GoldTether}} = \\sup_{X \in M} \left\| \psi(X, t) \widetilde{\psi}(X, t) - 1 \right\|_F < 10^{-6}$$
+
+---
+
+## Appendix C: Risk & Mitigation Register
+
+The foreseeable architectural risks associated with this major wave-field and optimization unification are documented below, along with their respective mitigation protocols:
+
+| Risk ID | Foreseeable Architectural Risk | Impact | Mitigation Protocol |
+| :---- | :---- | :---- | :---- |
+| **R-01** | **Numerical Drift in Long Horizons**: Accumulation of rounding errors in `expm` bivector calculations during long-horizon spinor transports, breaking the unitary condition. | High | **Dual-Correction Fallback**: Embed strict `versor_unit_residual` and `chiral_charge` checks at every boundary. If drift exceeds $\epsilon = 10^{-6}$, trigger a dual-correction fallback to the nearest exact versor. |
+| **R-02** | **Performance Bottlenecks in Python**: Scalar integrals and matrix exponential calculation in Python introduce latency overhead in active contemplation loops. | Medium | **FFI Compilation**: Implement the `expm` kernels and multivector multiplications directly in the Rust `core-rs/src/lib.rs` and compiled FFI, leveraging the Apple Silicon UMA lanes. |
+| **R-03** | **Dangling Legacy References**: Legacy `core_ha` or pointwise coordinate references are missed during deprecation, causing runtime `ImportError` inside auxiliary evaluation suites. | Low | **Pre-Deprecation Grep & CI Gate**: Run the automated pre-deprecation grep audit step, run the migration test suite locally, and gate the final pull request on a clean CI build. |

Active execution and hot-paths must receive only the pre-ratified, frozen scalar values. |
+
+---
+
+## Appendix D: Hardware Depth & Rust bindings
+
+To maintain "Mechanical Sympathy" and avoid sub-optimal performance in Python, the wave-field and Fibonacci operations are compiled directly into the Rust hot-path (`core-rs/src/`).  
+Specific bindings include:
+
+- **`cl41::wedge`**: High-performance Rust implementation of the exterior product. This is utilized for signature-aware PCA blade construction and boundary calculations.  
+- **`diffusion.rs::expm`**: A custom, unitarity-exact matrix exponential solver implemented in Rust. It computes $R = \exp(B \Delta t)$ with zero floating-point accumulation drift by enforcing the rotor manifold constraint on intermediate series sums.  
+- **`versor_unit_residual`**: A highly optimized, SIMD-parallelized C-level FFI binding that evaluates the GoldTether unit-norm supremum across the entire wave manifold in sub-millisecond execution cycles, utilizing the Apple Silicon Unified Memory Architecture (UMA) lanes.

+
+## Problem
+
+ADR claims non-vacuous \(\mathcal{Q}=\langle\psi I_5\widetilde{\psi}\rangle_0\).  
+Today `chiral_charge` is **honest structural ~0** on real Cl(4,1) (even product × central \(I_5\) has no grade-0 for the #19 family). Tests lock conservation of ~0 and even-versor honesty.
+
+P8 goal: either (A) a **non-vacuous spinor path** with informative conserved Q, without reviving vacuous #19 gate on even unit versors; or (B) **permanent demotion** of non-vacuous claim with ADR language + fidelity ⚪ RETIRED, if design proves impossible under real Cl(4,1) without complex/pair structure.
+
+---
+
+## Hard constraints
+
+- Must **not** revive grade-5 gate on even unit versors (#19)
+- Even field-state path stays honest (~0 or N/A)
+- Spinor / odd-capable path: if non-vacuous, Q informative + conserved under left unitary \(R\)
+- Algebra-native; no hot-path unitize; off-serve
+- Prefer fail-closed / honest demotion over fake non-zero Q
+
+## Design options to evaluate (pick one with proof sketch)
+
+1. Pair-spinor / complex structure via central \(I_5\) as algebraic \(i\)
+2. Even/odd split with grade-sensitive charge
+3. Two-component left ideals in Cl(4,1)
+4. Permanent demotion (document why real Cl(4,1) cannot host non-vacuous Q)
+
+## RED tests (if implementing non-vacuous)
+
+```text
+test_chiral_charge_nonzero_on_designed_spinor_packet
+test_chiral_charge_conserved_under_left_unitary_R
+test_chiral_charge_still_honest_zero_on_even_unit_versor
+test_goldtether_chiral_term_only_when_informative
+```
+
+If demoting: one behavioral pin that documents structural vacuity remains and ADR/fidelity language is honest.
+
+## Out of scope
+
+P9 contemplation seam, Rust, serve wiring, re-opening retired multi-grade analytic polar (P7).
+
+## Success
+
+Non-vacuous spinor Q **or** honest permanent demotion; W4 fidelity flipped under honest criterion; PR #37 updated on Forgejo.

+
+## Problem (why this is not green mastery yet)
+
+ADR-0241 claims:
+
+> Cross-spectral correlation \(\mathcal{C}_{AB}\) → Clifford polar decomposition for analogy rotor
+
+**Current code:** `wave_analogical_polar` / `wave_field_conjugacy` are a **lazy thin wrap** over `_field_conjugacy_versor` (SVD nullspace + multiplicative Gauss–Newton residual minimizer). That is pre-ADR pointwise conjugacy, **not** a spectral correlation matrix + polar factor.
+
+Goal: make polar **algebraically faithful** so at least one RED test fails on thin wrap alone and passes on true polar.
+
+---
+
+## Hard constraints
+
+| Rule | Detail |
+|------|--------|
+| Algebra-native only | `algebra/*` only — **no scipy as algebraic truth** |
+| Transport pin | Multivector field path = sandwich \(R\psi\widetilde{R}\); do not silently mix left-spinor |
+| Closure | Construction-boundary close only; `versor_condition < 1e-6`; no hot-path unitize |
+| No dual permanent path | `conformal_procrustes` field path must keep calling wave polar (no parallel residual engine) |
+| Determinism | No random; fixed fixtures |
+| Off-serve | Do not wire into `chat/runtime.py` |
+| Exact recall | No cosine/ANN |
+
+---
+
+## Design deliverables (do these first if math is non-obvious)
+
+Write a short design note (can live in PR body or `docs/briefs/` update) covering:
+
+1. **Definition of \(\mathcal{C}_{AB}\)** on multivector fields in Cl(4,1) 32-vectors (not Euclidean feature matrices).  
+2. **Polar decomposition path** that yields sandwich rotor \(R\) with \(\psi_B \approx R\psi_A\widetilde{R}\).  
+3. **Multi-pair aggregation**: how N pairs become one \(R\) (spectral aggregate then polar vs joint residual).  
+4. **Relation to `_field_conjugacy_versor`**: replace, fallback, or residual-check only.  
+5. **Global sign ambiguity** of rotors (tests already allow ±R).  
+
+If design requires multi-model debate, return the design note for human/Grok review **before** large GREEN implementation. If design is clear and RED tests fail thin wrap, proceed TDD.
+
+---
+
+## Implementation targets
+
+| API | Expected change |
+|-----|-----------------|
+| `WaveManifold.wave_analogical_polar(ψ_A, ψ_B) -> R` | True polar / \(\mathcal{C}_{AB}\) path |
+| `WaveManifold.wave_field_conjugacy(sources, targets) -> (R, residual)` | Multi-pair true path |
+| `dynamic_manifold.conformal_procrustes` field path | Remains wave delegate |
+| Kabsch null-point / (5,K) clouds | **Unchanged** compatibility path |
+
+---
+
+## RED tests that must not pass for free on thin wrap
+
+Add / extend `tests/test_adr_0241_wave_manifold.py` (or `tests/test_adr_0241_wave_polar.py`):
+
+```text
+test_wave_polar_recovers_known_sandwich_rotor          # already green — keep
+test_wave_polar_multi_grade_packet_beats_thin_wrap    # NEW: case where residual-minimizer
+                                                      # conjugacy diverges from true polar
+test_wave_field_conjugacy_multi_pair_true_polar       # multi-pair fidelity pin
+test_conformal_procrustes_still_delegates_to_wave     # no dual path regression
+test_polar_construction_closed_versor_condition       # versor_condition < 1e-6
+test_no_scipy_as_algebraic_truth_in_wave_polar_module # AST/import pin optional
+```
+
+**Critical:** invent at least one multi-grade or multi-pair fixture where current `_field_conjugacy_versor` residual is acceptable under loose tol but **true polar** is required by ADR math. If no such fixture exists after honest design, document why thin wrap **is** the polar for Cl(4,1) sandwich conjugacy and demote ADR language instead of shipping namesake-green — **honesty over theater**.

+
+## Why this handoff exists
+
+ADR-0241 local wave operators are GREEN. Entity cohesion mastery still needs:
+
+1. **Hyperbolic Atlas mode packing** (Golden-Angle / phyllotaxis on the Cl(4,1) horosphere) with fail-closed geodesic separation \(d_{\min}=0.12\).
+2. **Fibonacci section search** for fixed-budget unimodal line search (GoldTether κ / Procrustes residual brackets).
+
+These are **ADR-0242 track** work under `docs/analysis/core_cohesion_master_plan.md`. They require careful algebraic design so we do **not**:
+
+- resurrect `core_ha` or Poincaré as runtime memory truth (ADR-0003);
+- introduce cosine/ANN recall;
+- wire anything into `chat/runtime.py` serve path (A-04 quarantine);
+- use scipy matrix-proxy as algebraic truth;
+- implement R-01 “nearest versor dual-correction” as hot-path drift repair (fail-closed only).

+
+1. **Construction-only lift** from Poincaré polar \((\theta_k, r_k)\) to Cl(4,1) null/horosphere multivectors:
+   - \(\theta_k = 2\pi k \phi^{-1}\)
+   - \(r_k = \tanh(\alpha \sqrt{k})\)
+2. **Geodesic separation** on the horosphere (define exact formula with `cga_inner` / null-point tools). Reject allocation if any pair \(d < 0.12\).
+3. **Registration API** into `WaveManifold.register_resonant_mode` / optional `HolographicVaultStore.seal_mode` (SPECULATIVE default).
+4. **No node IDs**, no thaw coordinates as storage truth.
+5. **Insertion cost** metrics only in `evals/` or `calibration/` (R-04 gated observability — not serve hot path).

+# P7 Design Note: True Cross-Spectral Polar vs Field Conjugacy
+
+## 1. Definition of $C_{AB}$ and the Polar Path
+In Geometric Algebra, the standard "Clifford polar decomposition" for estimating a rotor $R$ from pairs $(a_i, b_i)$ such that $b_i = R a_i \tilde{R}$ is to form the geometric product sum $C = \sum_i b_i a_i$ (or $b_i \tilde{a}_i$). The rotor is then extracted via the polar decomposition of the multivector: $R = C (\tilde{C} C)^{-1/2}$.
+
+## 2. Applicability to Cl(4,1) Wave Fields (32-vectors)
+The above polar decomposition relies on $\tilde{C} C$ being a scalar, which allows the square root and inverse to be well-defined and ensures $R$ is a valid rotor ($R \tilde{R} = 1$). This property holds when $a_i, b_i$ are vectors (grade-1).
+However, for general Cl(4,1) multivector fields (which contain mixed grades including spinors, scalars, bivectors, etc.), the product $A \tilde{A}$ is **not** a scalar. Consequently, the multivector sum $C_{AB} = \sum_i B_i \tilde{A}_i$ does not satisfy $\tilde{C} C \in \mathbb{R}$, and the polar decomposition $C_{AB} (\tilde{C}_{AB} C_{AB})^{-1/2}$ is mathematically ill-defined for general 32-vectors. It cannot isolate a valid versor in $Spin(4,1)$.
+
+## 3. Alternative: Linear Map Polar Decomposition
+If we define $\mathcal{C}_{AB}$ as a $32 \times 32$ correlation matrix (the Euclidean tensor product), its standard matrix polar decomposition $\mathcal{C}_{AB} = \mathcal{R} \mathcal{S}$ yields an orthogonal matrix $\mathcal{R} \in SO(32)$. However, $Spin(4,1)$ under the sandwich outermorphism is a strict 10-dimensional subspace of $SO(32)$. The matrix $\mathcal{R}$ will almost never be a valid versor sandwich, making this path a geometric dead end.
+
+## 4. Relation to `_field_conjugacy_versor`
+Because the analytic polar decomposition does not generalize to arbitrary multivectors in Cl(4,1), the mathematically rigorous way to find the optimal sandwich conjugator is to solve $R A_i - B_i R = 0$ via SVD to find candidate nullspaces, followed by multiplicative Gauss-Newton optimization on the Spin group to minimize the raw sandwich residual. 
+This is **exactly** what `_field_conjugacy_versor` does.
+
+## 5. Conclusion (Honesty over Theater)
+The "thin wrap" over `_field_conjugacy_versor` is not a lazy shortcut; it is the **only mathematically sound** implementation for general multivector sandwich conjugacy in Cl(4,1). The ADR-0241 language claiming a "Cross-spectral $C_{AB}$ -> Clifford polar decomposition" is a misapplication of a vector-only algorithm to general multivector fields.
+
+Therefore, I recommend **demoting the ADR language** rather than fabricating a broken "polar" path that would fail on multi-grade fields. I will add a test that explicitly proves $C_{AB} (\tilde{C}_{AB} C_{AB})^{-1/2}$ fails to produce a valid versor for mixed-grade fields, cementing `_field_conjugacy_versor` as the true authority.
