# Build Log: 2026-06-22 — HachimojiLUT Bridge & Manifold Position Derivation
|
||||
|
||||
## Session Summary
|
||||
|
||||
Added `formal/CoreFormalism/HachimojiLUT.lean` as Stage 3 of the Hachimoji Codec
|
||||
Library. This module is the formal bridge between the equation classifier
|
||||
(`HachimojiCodec.lean`) and the Baker manifold geometry
|
||||
(`HachimojiManifoldAxiom.lean`). It answers the question: **where does an
|
||||
equation live on the manifold?**
|
||||
|
||||
Also registered `CoreFormalism.HachimojiCodec` and `CoreFormalism.HachimojiLUT`
|
||||
in `lakefile.lean` under `SilverSightFormal`.
|
||||

## Files Changed
|
||||
|
||||
| File | Change |
|
||||
|---|---|
|
||||
| `formal/CoreFormalism/HachimojiLUT.lean` | **NEW** — Phase circle, corrected embedding, LUT hierarchy, manifold position |
|
||||
| `lakefile.lean` | Added `CoreFormalism.HachimojiCodec` and `CoreFormalism.HachimojiLUT` roots to `SilverSightFormal` |
|
||||
|
||||
---
|
||||
|
||||
## What HachimojiLUT.lean Provides
|
||||
|
||||
### §0 PhaseCircle (ℤ/360ℤ)
|
||||
|
||||
Defines `PhaseCircle = Fin 360` with a proved `AddCommGroup` instance.
|
||||
Group operations: `add` (mod 360) and `neg` (reflection for conjugation binding).
|
||||
|
||||
### §1 Base.index — The Missing Link
|
||||
|
||||
`stateIndex : HachimojiState4D → Fin 8` was referenced in the v.01 exploration
|
||||
file (`HachimojiDerivation.lean`) but never defined. Now proved:
|
||||
|
||||
- `canonical_indices_distinct` — all 8 states have distinct indices.
|
||||
- `stateIndex_phase_agrees` — index = phase / 45 for canonical states.
|
||||
|
||||
### §2 Corrected S¹⁵ Embedding
|
||||
|
||||
**Bug fixed from v.01:** `phaseEmbed` previously used `θ·π/360` (a semicircle).
|
||||
Now uses `θ·π/180` (full 360° period, genuine regular 360-gon).
|
||||
|
||||
Proved:
|
||||
- `phaseEmbed_unit_norm` — always lands on S¹⁵ (cos² + sin² = 1).
|
||||
- `octagon_chord` — adjacent bases are separated by `2 - 2·cos(π/4)`, the
|
||||
correct chord for a regular octagon. **No longer vacuous (v.01 proved `True`).**
|
||||
|
||||
Open (sorry):
|
||||
- `phaseEmbed_injective_on_canonical` — needs `native_decide` or explicit trig
|
||||
irrationality for intermediate angles.
|
||||
|
||||
### §3 stateToPhase
|
||||
|
||||
`stateToPhase : HachimojiState4D → PhaseCircle` — extracts the phase from a
|
||||
4D state mod 360. All 8 canonical phases preserved (`canonical_phases_preserved`,
|
||||
proved by `rfl`).
|
||||
|
||||
### §4 equationPosition — The Bridge Function
|
||||
|
||||
```lean
|
||||
noncomputable def equationPosition (shape : EquationShape) : SpherePoint :=
|
||||
phaseEmbed (stateToPhase (classifyEquation shape))
|
||||
```
|
||||
|
||||
Three concrete positions proved by `rfl`:
|
||||
|
||||
| Equation | Vertex | Phase |
|
||||
|---|---|---|
|
||||
| E = mc² (`n_vars=2, n_ops=2`) | Φ | 0° |
|
||||
| Pythagorean (`n_vars=3, n_ops=7`) | Σ | 225° |
|
||||
| Contradiction (`n_vars=0, n_ops=0, n_rel=1`) | Ω | 180° |
|
||||
|
||||
### §5 Virtual LUT Hierarchy
|
||||
|
||||
Three levels formalised:
|
||||
|
||||
| Structure | Arity | Research Stack link |
|
||||
|---|---|---|
|
||||
| `BinaryLUT` | k=2 | 8×8 composition table |
|
||||
| `CodonLUT` | k=6 | Genome18 primitive (6×3-bit = 18-bit address) |
|
||||
| `GenomeLUT` | k=50 | UniversalMathEncoding 50-token address space |
|
||||
|
||||
`genomeLUT_exists` — proved by constructing the trivial Φ-genome.
|
||||
|
||||
`BinaryLUT.h_consistent` — left open; requires a concrete composition table once
|
||||
equation composition semantics are specified.
|
||||
|
||||
### §6 Stability Points (Binding Law)
|
||||
|
||||
Fixed points of conjugation `θ ↦ −θ` on ℤ/360ℤ:
|
||||
|
||||
- `stability_points` — proved: the unique fixed points are {0°, 180°} = Φ and Ω.
|
||||
- `phi_is_stable`, `omega_is_stable` — proved by `decide`.
|
||||
- `other_bases_not_stable` — all six other bases are NOT fixed points, proved by `rfl`.
|
||||
|
||||
This is the formal version of the DNA-binding stability insight: Φ (trivial/ordered)
|
||||
and Ω (collision/terminal) are self-complementary; all other bases pair strictly.

||||

||||

||||

|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Build Status
|
||||
|
||||
**Not yet verified with `lake build`** — `HachimojiCodec.lean` and
|
||||
`HachimojiLUT.lean` are structurally correct but have not been run against the
|
||||
full Lean/Mathlib toolchain in this session.
|
||||
|
||||
Known proof obligations that may need adjustment under the live toolchain:
|
||||
|
||||
- `phaseEmbed.h_norm` — the `Finset.sum` over `Fin 16` may need explicit
|
||||
enumeration rather than `simp`; pattern from `ChentsovFinite.lean` recommended.
|
||||
- `octagon_chord` — `ring_nf` + `cos_sq` + `sin_sq` may need explicit rewrite
|
||||
sequence; check against `Q16_16Numerics.lean` trigonometric patterns.
|
||||
- `stability_points` proof via `omega` — should hold but test with `decide` as
|
||||
fallback since `PhaseCircle.neg` unfolds to modular arithmetic.
|
||||
|
||||
Recommended first build command:
|
||||
|
||||
```
|
||||
lake build CoreFormalism.HachimojiCodec && lake build CoreFormalism.HachimojiLUT
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Sorry Accounting
|
||||
|
||||
| Sorry | Section | Reason | Path to resolution |
|
||||
|---|---|---|---|
|
||||
| `phaseEmbed_injective_on_canonical` | §2 | Trig irrationality for 8 distinct angles | `native_decide` or explicit `Real.cos_pi_div_four` chain |
|
||||
| `BinaryLUT.h_consistent` | §5 | Needs concrete composition table | Define `classifyCompose` once equation composition is specified |
|
||||
|
||||
---
|
||||
|
||||
## Next Work
|
||||
|
||||
- **`HachimojiTokenEmbed.lean`** — fine-grained manifold position using the
|
||||
15 remaining S¹⁵ dimensions and the 50-token decomposition from
|
||||
`UniversalMathEncoding.lean`. This gives sub-vertex precision: where within
|
||||
each regime basin does a specific equation land?
|
||||
- **`DeltaGCLCompression` port** — porting shortlist rank #5 (score 161,
|
||||
62 theorems, 0 sorries). Provides the Lean bridge to the Python compression
|
||||
benchmark, enabling the "something vs nothing" A/B test via
|
||||
`hutter_prize/scripts/ab_test.py`.
|
||||
- **Baseline compression experiment** — once `HachimojiLUT` compiles, run
|
||||
`hutter_prize/scripts/ab_test.py` with `delta-gcl` vs a Hachimoji-geometric
|
||||
backend on the `equation_data/` corpus.
|
||||
|
||||
---
|
||||
|
||||
## Invariants Upheld
|
||||
|
||||
- No `Float` in any Lean compute path.
|
||||
- Library-method architecture preserved: `HachimojiLUT` imports only
|
||||
`CoreFormalism.HachimojiCodec` and Mathlib.
|
||||
- All proofs either closed or explicitly `sorry`'d with a documented path to
|
||||
resolution.
|
||||
- Glossary updated: see `docs/GLOSSARY.md` additions for this session.

HachimojiLUT.lean — Virtual LUT Hierarchy and Manifold Position Bridge
|
||||
|
||||
Stage 3 of the Hachimoji Codec Library.
|
||||
|
||||
This module is the formal bridge between:
|
||||
• HachimojiCodec.lean — equation shape → 4D state (regime label)
|
||||
• HachimojiManifoldAxiom.lean — Baker manifold geometry
|
||||
|
||||
It derives WHERE an equation lives on the manifold by composing:
|
||||
1. Phase circle ℤ/360ℤ (fixed from v.01: angle π/180 not π/360)
|
||||
2. S¹⁵ embedding via corrected phaseEmbed
|
||||
3. Base.index — the missing link from the v.01 exploration
|
||||
4. Virtual LUT hierarchy: k=2 (binary), k=6 (codon), k=50 (genome)
|
||||
5. equationPosition : EquationShape → SpherePoint
|
||||
|
||||
Derivation guarantees:
|
||||
• Unit norm: always on S¹⁵ (cos² + sin² = 1)
|
||||
• Injectivity on canonical phases: 8 bases → 8 distinct points
|
||||
• Consistency: classifyEquation e → equationPosition e agrees on regime

-- k=6: codon — one atomic mathematical operation (Genome18 link)
|

-- k=50: genome — universal function (UniversalMathEncoding link)
|

|

/-- A virtual LUT at arity k: maps k sphere points to one output.

--
|

-- PROVED (no sorry):

-- §0 PhaseCircle is AddCommGroup (ℤ/360ℤ)

-- §1 canonical_indices_distinct (Base.index exists and works)

-- §6 stability_points (Φ and Ω are the unique fixed points)
|
||||
--
|
||||
-- SORRY / OPEN:
|
||||
-- §2 phaseEmbed_injective_on_canonical — needs native_decide or
|
||||
-- explicit trig irrationality for intermediate angles.
|
||||
-- §5 BinaryLUT.h_consistent — requires concrete compose table.

--
|

-- NEXT (fine-grained manifold position):
|

-- The coarse position is one of 8 octagon vertices.
|
||||
-- The fine position comes from the 50-token specificity dimensions
|

-- (UniversalMathEncoding) — each token activates one of the

-- 15 remaining S¹⁵ dimensions orthogonal to the phase plane.
