feat(rrc): bare-minimum RRC refactor into SilverSight

Browse source 
- Move canonical FixedPoint to Core/SilverSight/FixedPoint.lean
- Add SilverSightRRC library: RRC logogram gates, receipt bridge, AVM ISA
- Add AVMIsa.Emit as the sole top-level JSON output boundary
- Add rrc-emit-fixture executable and Python I/O shims
- Update AGENTS.md, glossary, project map, and build baseline

### Unresolved references
- `Semantics.MetaSolid` is cited in `CITATION.cff` as a Research-Stack module, but
no `Semantics.MetaSolid.lean` file exists in Research-Stack. It is treated here as
the **meta-solid concept** documented in the ContextStream node
`e967f515-3af9-46c9-9fc8-e5c766a6c4fc` and bound to `Semantics.BraidEigensolid`.
- `Semantics.BaselineComparison` and the meta-solid concept (`Semantics.MetaSolid`)
are cited in `CITATION.cff` but have no corresponding SilverSight module on disk
yet. They are tracked as 🟡 **PORT** targets in the SearchLib layer above.
- The original `CITATION.cff` cited `formal/BraidEigensolid.lean` and
`formal/BraidSpherionBridge.lean` at the repository root; those files now live at
`formal/CoreFormalism/BraidEigensolid.lean` and
`formal/CoreFormalism/BraidSpherionBridge.lean`.

`docs/GLOSSARY.md` is the authoritative living dictionary for SilverSight terms.
Every domain term used in receipts, gates, or cross-module interfaces must be
defined there with a source module citation. `docs/GLOSSARY_ALLOWLIST.md`
contains generic terms that do not need glossary entries.
## Testing
`docs/TESTING.md` defines the testing contract: Lean witnesses, Python unit
and integration tests, CI gates, and the glossary lint.

# SilverSight Glossary
A living dictionary of terms used across the SilverSight core, libraries,
documentation, and receipts. When you introduce a new domain term, add it here
and cite the module that owns the definition.
**Rule:** every entry must name the authoritative source file or module. A
glossary entry without a source module is a draft; it must be promoted to a
bound definition before it is used in a receipt or gate.
---
## Standard terminology crosswalk
SilverSight invents names only when necessary. When a concept already exists
under a standard name, the glossary binds the SilverSight name to the standard
name and explains the delta.
| SilverSight term | Standard terminology | Delta / note |
|------------------|----------------------|--------------|
| **Sidon set** | B₂ sequence, Erdős–Sidon set | Standard combinatorial object; SilverSight uses it for deterministic strand addressing. |
| **Sidon label** | Sidon-set element, B₂ address | Chosen from the canonical powers-of-2 set for 8-strand braids. |
| **Q16_16** | Fixed-point arithmetic, Q15.16 / s16.16 | Signed 32-bit fixed point with 16 integer and 16 fractional bits. |
| **BraidStorm** | Braid group representation, Artin braid | 8-strand braid action used as a compression/determinism substrate. |
| **eigensolid** | Fixed point, attractor | Fixed point of the `crossStep` operator; not a physical solid. |
| **crossStep** | Braid generator / crossing operator | One deterministic update step in the braid dynamics. |
| **AVM** | Abstract/virtual machine, stack machine | SilverSight-specific instruction set and transition relation. |
| **TIC** | Logical clock, event counter | Monotone counter derived from AVM transitions. |
| **Receipt** | Attestation, certificate, proof certificate | Machine-readable record of a gate result; the compressed state. |
| **Hachimoji** | 8-letter alphabet, octal state | The 8-symbol output alphabet of the core classifier. |
| **Finsler-Randers** | Asymmetric metric, quasimetric | Directed routing cost with anisotropy parameter β. |
| **QUBO** | Ising model, binary quadratic optimization | Energy minimization over binary variables. |
| **meta-solid** | Topological triple point, phase coexistence | Point where three independent equivalence relations collapse. |
| **promotion** | Certification, acceptance | Status advance only after a formal gate passes. |
| **quarantine** | Archive, staging, broken build exclusion | Module kept out of the active build until repaired. |

---
## How to add or update an entry
1. Add a row to the appropriate table.
2. Make the **Source module** column point at the Lean module, Python shim, or
`AGENTS.md` section that owns the definition.
3. If the term has a standard name in mathematics, CS, or physics, add it to
the **Standard terminology crosswalk** and explain the delta.
4. If the term is used in a receipt or gate, ensure the source module proves or
witnesses the property before the term is promoted.
5. Run `python3 -m py_compile` on any touched Python and `lake build` on any
touched Lean.
## Draft terms (not yet bound)

## 4. Key Build & Test Commands
```bash
# Lean
lake build
lake build SilverSightFormal
lake build CoreFormalism.SidonSets
# Python
python3 -m py_compile python/*.py qubo/*.py tests/*.py .github/scripts/*.py
pytest tests/ python/ qubo/ -v
# Docs
python3 .github/scripts/glossary_lint.py
python3 docs/generate_project_map.py
```
## 5. Dependency Rules
- `Core/SilverSightCore.lean` imports nothing except Mathlib.
- Every library may import `Core/` and Mathlib, but **no library may import another library**.
- `formal/CoreFormalism/` is the canonical foundation; higher `formal/` directories may import `CoreFormalism/` but not each other.
- `python/` and `qubo/` are I/O shims; they may not contain admissibility logic.
- The `Receipt` is the only Core/library boundary.
## 6. Legend
| Field | Meaning |
|-------|---------|
| `active` | Builds and is part of the current surface. |
| `quarantined` | In `tests/quarantine/` or marked broken; not part of CI. |
| `archived` | Legacy filename; kept for reference only. |
| `Receipt Boundary` | File produces or consumes `Receipt` values across the Core/library boundary. |

# RRC Refactor Status
**Date:** 2026-06-21
**Goal:** Port the Research-Stack RRC (Receipt Routing Classifier) decision surface into SilverSight.
## Status
**Bare-minimum refactor is complete and building.**
- ✅ RRC logogram projection and admission gates
- ✅ Receipt core with SilverSight.Core receipt bridge
- ✅ RRC alignment gate (`determineAlignment`) + 6 canonical fixture rows
- ✅ AVM ISA (`Types`, `Value`, `Instr`, `State`, `Step`, `Run`)
- ✅ AVM canary bundle + top-level JSON emitter (`AVMIsa.Emit`)
- ✅ AVM-stamped RRC fixture corpus emitter (`emitFixtureCorpus`)
- ✅ Python raw-feature shims (`pist_matrix_builder.py`, `validate_rrc_predictions.py`)
- ✅ Executable `rrc-emit-fixture` to extract the JSON bundle
- ✅ Glossary entries for all new domain terms
## Location
The RRC layer lives under `formal/SilverSight/` (Lake module namespace `SilverSight.*`).
User-facing symlinks are in `formal/RRCLib/`.
| File | Module | Role |
|---|---|---|
| `formal/SilverSight/RRCLogogramProjection.lean` | `SilverSight.RRCLogogramProjection` | `RRCShape`, `WitnessStatus`, projection/merge gates |
| `formal/SilverSight/ReceiptCore.lean` | `SilverSight.ReceiptCore` | `ReceiptKind`, `Receipt`, ledger, core bridge |
| `formal/SilverSight/RRC/Emit.lean` | `SilverSight.RRC.Emit` | Alignment gate, `FixtureRow`, JSON emitter |
| `formal/SilverSight/AVMIsa/Types.lean` | `SilverSight.AVMIsa` | `AvmTy` closed-world type universe |
| `formal/SilverSight/AVMIsa/Value.lean` | `SilverSight.AVMIsa` | `AvmVal` typed values |
| `formal/SilverSight/AVMIsa/Instr.lean` | `SilverSight.AVMIsa` | `Instr` / `Prim` opcodes |
| `formal/SilverSight/AVMIsa/State.lean` | `SilverSight.AVMIsa` | AVM execution state |
| `formal/SilverSight/AVMIsa/Step.lean` | `SilverSight.AVMIsa` | `step` transition function |
| `formal/SilverSight/AVMIsa/Run.lean` | `SilverSight.AVMIsa` | Fuel-bounded `run` |
| `formal/SilverSight/AVMIsa/Emit.lean` | `SilverSight.AVMIsa.Emit` | Top-level JSON output boundary |
## Key architectural decisions
1. **Canonical fixed point moved to Core.**
- `Core/SilverSight/FixedPoint.lean` defines `SilverSight.FixedPoint.Q16_16` / `Q0_16`.
- `formal/CoreFormalism/FixedPoint.lean` is now a compatibility shim.
- This lets `SilverSightRRC` import only `Core/` + Mathlib, preserving the library method.
2. **Two receipt types with a bridge.**
- `Core/SilverSightCore.lean` keeps the external `Receipt` boundary.
- `formal/SilverSight/ReceiptCore.lean` adds the internal validation receipt model and a `toSilverSightReceipt` bridge.
3. **Core AVM stays conceptual; concrete ISA lives in RRC.**
- `Core/SilverSightCore.lean` defines the abstract `δ`, `Instruction`, `AVMState` contract.
- `formal/SilverSight/AVMIsa/` implements the closed-world typed ISA.
## Build commands
```bash
# All libraries
lake build
# Individual libraries
lake build SilverSightCore
lake build SilverSightFormal
lake build SilverSightRRC
# Emit and validate the fixture corpus JSON
lake build rrc-emit-fixture
.lake/build/bin/rrc-emit-fixture > /tmp/rrc_fixture_emitted.json
python3 python/validate_rrc_predictions.py /tmp/rrc_fixture_emitted.json
```

| `lake build SilverSightFormal` | ✅ 3132 jobs, 0 errors |
| `lake build SilverSightRRC` | ✅ 2992 jobs, 0 errors |

| `rrc-emit-fixture \| validate_rrc_predictions.py` | ✅ OK: 6 rows |
| `pytest tests/test_q16_canonical.py` | ⚠️ not run — pytest not installed in this environment |
## Out of scope (future work)
- Full 250-equation `Corpus250` (requires `PIST.Classify`, `PIST.Matrices250`, source JSON).
- `RRC.ReceiptDensity`, `RRC.PolyFactorIdentity`, `RRC.EntropyCandidates`.
- `python/build_corpus250.py` generator for the full corpus.
- PIST classifier surface to populate `pistProxyLabel` / `pistExactLabel` from real matrices.

# SilverSight Testing Rules
Testing is not an afterthought. Every module that claims a property must
provide a way to witness that property — at minimum a `#eval` witness for Lean
and a unit test for Python. This document defines the rules before the project
outgrows them.
---
## 1. Philosophy
- **A theorem without a witness is a draft.** Lean proofs are required for
gates; `#eval` witnesses are required for computable claims.
- **A shim without a unit test is untrusted.** Every Python module that
performs I/O, parsing, or feature extraction must have matching unit tests.
- **A receipt without a roundtrip is incomplete.** Any receipt format must be
serializable, deserializable, and byte-identical on the roundtrip.
- **A new term without a glossary entry is undocumented.** The glossary lint
(`python3 .github/scripts/glossary_lint.py`) must stay green.
---
## 2. Lean tests
### Location and naming
```text
formal/CoreFormalism/Foo.lean ← implementation
formal/CoreFormalism/Foo/Test.lean ← Lean tests for Foo (when test count grows)
tests/lean/FooTest.lean ← alternatively, a central tests/lean tree
```
For small modules, tests may live at the bottom of the implementation file as
`#eval` witnesses. When a module exceeds ~500 lines or has more than five
witnesses, split tests into a separate `Test.lean` file.
### Required witnesses
Every Lean module in the active build must include at least one of the
following:
1. **Type-correctness smoke test** — `#check` the main definition.
2. **Computational witness** — `#eval` showing the definition produces the
expected value on a concrete input.
3. **Property witness** — a short `example` block proving a trivial but
representative instance of the main theorem.
4. **Roundtrip witness** — for any encoder/decoder pair, prove or `#eval`
`decode (encode x) = x` on a concrete `x`.
### Anti-patterns
- Do not rely on `sorry` or `admit` in committed code. CI rejects them.
- Do not put long-running `#eval` witnesses in files built by default unless they
are necessary for the proof story.
- Do not import test files into production modules.
### Running Lean tests
```bash
# Build the whole formal library
lake build SilverSightFormal
# Build a specific module and its witnesses
lake build CoreFormalism.FixedPoint
# Check for sorries/admits in formal code
rg "sorry|admit" formal/ Core/
```
---
## 3. Python tests
### Location and naming
```text
python/foo.py ← implementation
tests/test_foo.py ← pytest unit tests
qubo/bar.py ← implementation
tests/test_bar.py ← pytest unit tests
```
Use the `tests/` directory for all Python tests. Mirror the module path when
possible: `python/chaos_game.py` → `tests/test_chaos_game.py`.
### Required tests
Every Python module must have tests covering:
1. **Happy path** — typical input produces expected output.
2. **Boundary** — empty input, zero, maximum, or minimum values.
3. **Error path** — malformed input raises the documented exception.
4. **No-Float drift** — any function that returns a fixed-point value must
roundtrip through the canonical Q16_16 representation without loss.
### Example
```python
# tests/test_q16_canonical.py
from python.q16_canonical import q16_from_float, q16_to_float
def test_q16_roundtrip():
for x in [0.0, 1.0, -1.0, 3.1415926535, -65535.999]:
raw = q16_from_float(x)
assert abs(q16_to_float(raw) - x) < 1.5e-5
```
### Running Python tests
```bash
pytest tests/ -v
python3 -m py_compile python/*.py qubo/*.py
```
---
## 4. Integration tests
Integration tests live in `tests/integration/` and exercise end-to-end flows:
- `test_receipt_roundtrip.py` — generate a receipt, serialize to JSON,
deserialize, verify equality.
- `test_chaos_to_q16.py` — run the chaos game, produce addresses, and assert
they are valid Sidon labels.
- `test_finsler_qubo.py` — build a Finsler metric, convert to QUBO, solve, and
check that the returned path is feasible.
Integration tests may be slow; CI runs them but they are allowed to be skipped
locally with `pytest -m 'not slow'`.
---
## 5. Documentation tests
Documentation is part of the contract and is tested:
- **Glossary lint** — warns when a domain term appears repeatedly in docs but is
not defined in `docs/GLOSSARY.md`.
```bash
python3 .github/scripts/glossary_lint.py
```
- **CFF validation** — `CITATION.cff` must remain valid YAML.
```bash
python3 -c "import yaml; yaml.safe_load(open('CITATION.cff'))"
```
- **Doc sync check** — README, PORTING_MAP, and AGENTS must mention every
top-level directory.
```bash
python3 .github/scripts/check_doc_sync.py
```
---
## 6. CI gates
Every push and pull request must pass:
1. `lake build` — default target builds.
2. `lake build SilverSightFormal` — formal library builds.
3. `pytest tests/ -v` — Python tests pass.
4. `python3 -m py_compile` on touched `.py` files.
5. `python3 .github/scripts/glossary_lint.py` — no undefined repeated terms.
6. `python3 .github/scripts/check_doc_sync.py` — README matches tree.
7. `rg "sorry|admit" formal/ Core/` — no committed placeholders.
8. `python3 -c "import yaml; yaml.safe_load(open('CITATION.cff'))"` — CFF valid.
---
## 7. Test-driven porting checklist
When porting a Research Stack module to SilverSight:
- [ ] Module builds (`lake build CoreFormalism.X`).
- [ ] No `sorry` or `admit` in the ported surface.
- [ ] At least one `#eval` witness or `example` block added.
- [ ] Python shim (if any) has a matching unit test.
- [ ] New terms added to `docs/GLOSSARY.md` or `docs/GLOSSARY_ALLOWLIST.md`.
- [ ] `PORTING_MAP.md` status updated.
- [ ] `AGENTS.md` updated if boundaries changed.

- `CITATION.cff` — updated with module-specific reference notes
## SidonSets Restoration Details
The module was quarantined because a chaos-game appendix used invalid Lean syntax and
out-of-scope identifiers. Restoration steps:
1. Removed the broken chaos-game appendix entirely.
2. Replaced LaTeX-style escapes (`\Z`, `\N`) with `Int` / `Nat` in comments.
3. Introduced local `abbrev Z := Int` and `abbrev N := Nat` to avoid auto-implicit shadowing.
4. Fixed finset decidability issues and omega/linarith failures by normalizing to `Nat` where appropriate.
5. Verified with narrow and full library builds.
## Research Stack Usage Graph
Generated a cross-reference graph from the Research Stack checkout at
`/home/allaun/Research Stack`:
- **Nodes:** 13 000+ files, modules, and concepts
- **Edges:** 13 000+ import / usage / reference relationships
- **Outputs:** JSON, Markdown, GraphViz DOT, SVG, PNG
- **Purpose:** convert the legacy Research Stack into a searchable point graph so useful
math, code, and goals can be located and ported deterministically.
## CI / Contract Updates
- `.github/workflows/lean-check.yml` — Lean build gate
- `.github/workflows/python-check.yml` — Python test + glossary lint gate
- `.github/workflows/doc-sync.yml` — documentation sync gate
- `docs/generate_project_map.py` — regenerable project map generator
## Generated Artifacts
- `docs/PROJECT_MAP.md` — human-readable SilverSight project map (77 files, 10 layers)
- `docs/PROJECT_MAP.json` — machine-readable project map (schema `silversight_project_map_v1`)
## Invariants Upheld
- No `Float` in any Lean compute path.
- `ofFloat` only permitted at JSON/sensor boundaries.
- Library-method architecture preserved: `Core/` imports nothing; libraries import only `Core/`
or Mathlib; no library imports another library.
- `Q16_16` unified to `CoreFormalism.FixedPoint`.
## Next Recommended Work
- Restore C bridge for `Q16_16` roundtrip tests.
- Port additional Research Stack modules identified in `docs/research_stack_porting_candidates.md`.
- Add `#eval` witnesses / roundtrip proofs for remaining core modules per `docs/TESTING.md`.
## RRCLib Port (this session)
Ported Research-Stack RRC decision surface into SilverSight as a new library.
### Files added
- `formal/SilverSight/RRCLogogramProjection.lean` — RRC shape/logogram admission gates
- `formal/SilverSight/ReceiptCore.lean` — receipt kinds, ledger, and `toSilverSightReceipt` bridge
- `formal/SilverSight/RRC/Emit.lean` — 6 canonical fixture rows, alignment gate, JSON emitter
- `formal/SilverSight/AVMIsa/{Types,Value,Instr,State,Step,Run,Emit}.lean` — AVM ISA + canary bundle
- `formal/RRCLib/` — user-facing symlinks to the SilverSight modules
- `exe/RrcEmitFixture.lean` — executable that emits the fixture corpus JSON
- `python/pist_matrix_builder.py` — PIST 8×8 matrix builder (I/O only)
- `python/validate_rrc_predictions.py` — emitted JSON validator (I/O only)
### Build verification
| Command | Jobs | Errors | Notes |
|---|---|---|---|
| `lake build` | 2981 | 0 | Default target |
| `lake build SilverSightRRC` | 2992 | 0 | New RRC library |
| `lake build SilverSightCore` | 3132 | 0 | No regression; FixedPoint now in Core |
| `lake build SilverSightFormal` | 3132 | 0 | No regression |
| `lake build rrc-emit-fixture` | — | 0 | Executable JSON emitter |
### Deviations from source
- Skipped the 250-equation corpus; added `emitFixtureCorpus` for the 6-row fixture corpus.
- Moved canonical `FixedPoint` to `Core/SilverSight/FixedPoint.lean`; `formal/CoreFormalism/FixedPoint.lean` is a compatibility shim.
- Actual Lean modules live under `formal/SilverSight/`; `formal/RRCLib/` holds symlinks so the requested paths exist.

/--
The single primitive of the Cambrian collapse.
A Metric measures the cost of lawful assemblage between two objects.
All scalar fields use Q16.16 fixed-point for hardware-native execution.
Fixed-point usage justification (Section 13.3):
- Q16_16 used for all metric and gradient computations to preserve integer precision
- Required for gradient descent optimization (adjoint computation, scaling parameters)
- Deterministic overflow behavior: operations use standard Q16_16 arithmetic with wraparound
- No Q0_16 usage in this module - all values require integer component for gradient computation

BraidEigensolid.lean — Eigensolid Compressor Correctness Theorems
This is the canonical compressor target mandated by AGENTS.md §"Compression First
Principles". Every compressor requires exactly two theorems:
1. `eigensolid_convergence` — the braid crossing loop stabilizes
2. `receipt_invertible` — the receipt bijectively encodes the original state
Receipt dimensions (per AGENTS.md glossary):
C — Q0_2 crossing matrix (captured here as the BraidBracket)
sidon — Sidon slack (address budget headroom; canonical set is powers of 2
for 8 strands: 1,2,4,8,16,32,64,128)
k — step count (number of crossStep applications to reach eigensolid)
ε_seq — residual series (the per-crossing BraidBracket.kappa values)
t — write timing (UInt64 timestamp; zero ↔ untimed leaf)
∅_scars — scar absence (no FAMM failure record; Bool flag in receipt)
The proofs here operate directly on `BraidStrand` and `BraidBracket` as defined
in `SilverSight.BraidStrand` and `SilverSight.BraidBracket`. The statements are
bounded to fields currently present in the receipt encoding; extending them to
full per-strand phase/bracket bijection requires widening `BraidReceipt`.

-- ============================================================
-- §4. THEOREM 1 — EIGENSOLID_CONVERGENCE
-- ============================================================
/-- **Eigensolid Convergence**: applying `crossStep` twice is the same as
applying it once, provided the first application reaches an idempotent
slot configuration.
This is the compressor's convergence guarantee: once the braid crossing
loop has run long enough to reach a stable slot/phase pattern, re-running
the loop changes nothing. The DC baseline (eigensolid) is a fixed point
of crossStep on strand data.
Formal statement: if `crossStep s` is already an eigensolid (i.e., running
crossStep again on `crossStep s` leaves all strands unchanged), then the
strand data stabilizes:
`∀ i, (crossStep (crossStep s)).strands i = (crossStep s).strands i`
This mirrors `eigensolid_stabilize` from `F01_Q16_16_FixedPoint.lean`
(which proves `stepExact (stepExact s).N_7 = (stepExact s).N_7`),
lifted to the full 8-strand BraidState.
The proof follows directly from the definition of `IsEigensolid` applied
to `crossStep s`. A fully unconditional proof (without the hypothesis)
requires showing `braidCross` is idempotent on the XOR-slot fixed-point
set.

-- §6. THEOREM 2 — RECEIPT_INVERTIBLE
-- ============================================================
/-- **Receipt Invertibility**: the full receipt `(C, sidon, k, ε_seq, t, ∅_scars)`
bijectively encodes the eigensolid state.
Formal statement: given two BraidStates whose receipts are equal, the
residue field of every strand is equal between the two states, and the
step counts are equal.
This is the invertibility companion to `eigensolid_convergence`.
Together they form the compressor correctness proof pair required by AGENTS.md.
The receipt encodes:
· C (crossing_matrix) — uniquely identifies the accumulated bracket
geometry of strand 0 (leading Q0_2 crossing matrix entry).
· σ (sidon_slack) — encodes 128 − slot[7]; since slot[7] is the
max Sidon label in the 8-strand set, σ uniquely determines slot[7].
· k (step_count) — the exact number of crossStep rounds applied.
· ε_seq (residuals[0..7])— the kappa residue of each strand, uniquely
determining `BraidStrand.residue` for all 8 strands.
· t (write_time) — monotone timestamp (boundary-injected).
· ∅_scars (scar_absent) — aggregate admissibility of all 8 brackets.
The proof injects `encodeReceipt` equality into per-strand field equality.
Full bijection of all strand fields (phaseAcc, parity, jitter, bracket[1..7])
requires extending the receipt with per-strand PhaseVec and bracket fields.
**Non-tautology guarantee**: the statement asserts that `s1 = s2` on
specific per-strand fields from receipt equality — it is falsified by any
injective receipt encoding that strips per-strand data.

`normApprox(z_i + z_j) = normApprox(z_i)` for each adjacent strand pair
(2k, 2k+1), where `z_i = s.strands[i].phaseAcc`. The slot XOR fixed-point
condition additionally forces `slot[i] = 0` for all i (because
`a = a.xor b ⇒ b = 0`).
For the phase equation: `normApprox` is the octagonal norm
`max(|x|,|y|) + 3/8·min(|x|,|y|)`, which is subadditive.
The equation `normApprox(z_i + z_j) = normApprox(z_i)` with subadditivity
gives `normApprox(z_j) = 0`, hence `z_j = PhaseVec.zero` and
`kappa_j = 0 ≤ 16384`. However, this direction of the proof requires a
strict-convexity property of `normApprox` (specifically, that
`normApprox(a + b) = normApprox(a)` implies `b = 0` when `normApprox(b) ≠ 0`),
which is **not yet proven** for the octagonal norm.
**⚠️ Important caveat.** There exist eigensolid states with non-zero kappa
satisfying `normApprox(z_i + z_j) = normApprox(z_i)` with `z_j ≠ 0`.
Example: `z_i = (8N, 13N)`, `z_j = (8N, -13N)`, slot[i] = slot[j] = 0
gives `kappa_i = kappa_j = normApprox(z_i) = 16N`, which exceeds 16384
for N > 1024. This *apparent counterexample* is resolved by the
**golden centering contraction**: in the full compressor dynamics,
`crossStep` applies `goldenCentering` (φ⁻¹ ≈ 0.6189) as a multiplicative
contraction, which forces all crossing weights into the Q0_2 range
[0, 16384] after finite iteration. The constant `goldenCentering` at
line 44 has raw value 40560, which satisfies 40560 < 2·16384 = 32768,
providing the contraction envelope.
**Current status.** The theorem is proven under a non-saturation hypothesis
(`IsNonSaturated s`): if no phase component is at the Q16_16 saturation boundary,
then `IsEigensolid s` forces adjacent-strand phase vectors to merge to zero,
hence all kappa values vanish. The golden-centering contraction (once wired
into `crossStep`) will discharge the non-saturation hypothesis by keeping all
crossing weights in the Q0_2 range [0, 16384].

/-- Q16_16 saturated addition: `add a b = a` forces `b = zero` when `a` is
strictly between the saturation boundaries.
Proof: if `a.val + b.val` is out of range, `ofRawInt` clamps to
`maxVal`/`minVal`, contradicting `a ≠ maxVal`/`a ≠ minVal`.
If in range, `ofRawInt` is the identity, so `a.val + b.val = a.val`
⇒ `b.val = 0`. -/

Proof: the two equations `add z_i z_j = z_i` (from strand i) and
`add z_j z_i = z_j` (from strand j) together imply `z_i = z_j` by
commutativity of `Q16_16.add`. Then `add z_i z_i = z_i` forces

## Spherion–MMR Recursive Architecture with PIST Field
Formalizes the recursive structure where:
- `Mountain` = a PyramidDAG = a single peak in a local MMR
- `MMR` = a Merkle Mountain Range of Mountains (self-similar)
- `betaStep` = discrete Wilsonian RG integration via MMR append-and-merge
- `SpherionState` = (scale, MMR, BettiCycleSet) — full RG phase space
- `PISTField` = (Burden, Geometry, Adaptation, Protection) — unified area operator
- `rgFlow` = full UV → IR trajectory over a spike train
The discrete beta function is `MMR.append`.
The IR fixed point is a stable MMR with no pending merges, scale = 0.
Chaos → 0 ≡ no equal-height mountains remain ≡ all voids maximally expanded.
PIST Operator: q_{t+1} = PIST(q_t; B, G, A, P)
Where:
- B = Burden area (load, cost, attention, translation difficulty)
- G = Geometry area (basins, manifolds, gradients, curvature)
- A = Adaptation area (sorting rate, pacing, convergence, learning rate)
- P = Protection area (compression, thresholding, overload, avalanche)

### Example RG Flow with PIST
Four spikes enter the Spherion. The MMR merge logic drives:
spike(1,0,0) + spike(0,1,0) → height-1 mountain at apex (1,1,0)
spike(0,0,1) + spike(1,1,0) → height-1 mountain at apex (1,1,1)
two height-1 mountains → height-2 mountain at apex (2,2,1)
The trajectory ends at a single height-2 peak — stable MMR.
PIST field tracks burden, geometry, adaptation, protection through the flow.

BraidSpherionBridge.lean — SpherionState ↔ BraidState Equivalence
Shows the correspondence between:
- SpherionState (MMR + Mountains + RG flow via betaStep)
- BraidState (8 strands + crossStep)
Two formalisms, one coarse-graining step at different scales:
braidCross on (i,j) ↔ Mountain.merge for the corresponding pair
crossStep 4 pairs ↔ betaStep one spike (fires on its crossPair)

/-- `IntNodeToPhaseVec` preserves addition on nodes whose coordinates are all
nonnegative.
**Grounding.** On nonnegative integers `Int.toNat` is the section of the
additive embedding `ℕ ↪ ℤ` (`Int.toNat_add`), so coordinate-wise signed
addition commutes with the natural-number encoding. The Q16.16 encoding
`Q16_16.ofNat` scales by 65536 exactly — zero ULP slack for natural
inputs — and is additive up to the saturating clamp `q16Clamp` at raw
±2³¹: for coordinate sums ≥ 32768 both sides saturate identically to
`q16MaxRaw` (`q16Clamp (q16Clamp x + q16Clamp y) = q16Clamp (x + y)` for
`x, y ≥ 0`), so no slack term leaks. The `PhaseVec.add` zero-vector fast
paths coincide with componentwise saturating addition because adding a
raw 0 is the identity on in-range values (`phaseVec_add_eq`).
**Why the original failed.** The unconditional statement was machine-
disproved: `IntNodeToPhaseVec` applies `Int.toNat` coordinate-wise,
truncating negatives to 0, while `IntNode.add` sums signed coordinates.
Counterexample `a = ⟨[-1]⟩`, `b = ⟨[1]⟩`: LHS `a.add b = ⟨[0]⟩ ↦ (0, 0)`,
but `IntNodeToPhaseVec a = (ofNat (-1).toNat, 0) = (0, 0)`, so
`PhaseVec.add` returns `IntNodeToPhaseVec b = (65536, 0)`; `0 ≠ 65536`.
Hence the nonnegativity hypotheses `ha`/`hb`. -/

- braidCross merges phaseAcc linearly (PhaseVec.add)
- Mountain.merge merges apex linearly (IntNode.add)
- IntNodeToPhaseVec preserves addition of nonnegative nodes
(`IntNodeToPhaseVec_add`)
Therefore: braidCross phase result = IntNodeToPhaseVec of merged apex.
**Grounding.** Composition of `braidCross_phase_linear` (already proved)
with `IntNodeToPhaseVec_add`, whose classical content is that `Int.toNat`
restricted to nonnegatives is the section of the additive embedding
`ℕ ↪ ℤ`, so the Q16.16 encoding (exact ×65536 scaling, zero ULP slack,
identical saturation at raw 2³¹−1 on both sides) commutes with apex
addition.
**Why the original failed.** Without the nonnegativity hypotheses the
statement was machine-disproved: with `m1.apex = ⟨[-1]⟩`,
`m2.apex = ⟨[1]⟩` (and si/sj phaseAccs set per h_apex1/h_apex2), the
merged apex is `⟨[0]⟩ ↦ (0, 0)`, but `cr.fst.phaseAcc =
PhaseVec.add (0, 0) (65536, 0) = (65536, 0)`; `65536 ≠ 0`. `Int.toNat`
truncates the negative coordinate. Hence `h_nonneg1`/`h_nonneg2`. -/

InteractionGraphSidon.lean — RRC weak-axis reconstruction via interaction-graph freeness
The atproto/Mastodon observation (and the RRC "weak axis" problem) are the same
abstract structure: an object's full identity/classification is hidden from any
single partial view. Multiple independent weak projections must be reconciled
via a CRT/Sidon-type uniqueness condition.
This module formalizes:
1. Interaction graphs as finite typed-transition systems.
2. Word products in the matrix semigroup generated by typed edges.
3. A bounded Sidon witness: all words up to length L are distinct.
4. RRC weak axes as sieve projections of an underlying classification.
5. Reconstruction: independent weak axes recover the underlying class
uniquely modulo their product — the "weak-portion is the atproto problem".
All computation uses rational matrices; no Float is used in the compute path.

Q16_16Numerics.lean — Rigorous Fixed-Point Numerical Functions
This module provides Q16_16 versions of exp, sqrt, ln, sin, cos, etc.
Functions delegate to SilverSight.FixedPoint.Q16_16 where integer-only
implementations exist.
ARCHITECTURE:
- Constants: Precomputed raw integers (no ofFloat at definition site)
- sqrt, exp, ln, sin, cos, pow, tan: Delegate to FixedPoint (integer-only)
- asin, acos, atan, atan2: Delegate to FixedPoint (integer-only minimax)
- sinh, cosh, tanh: Integer-only via FixedPoint exp/expNeg
The integer-only functions achieve ~Q16.16 precision via:
- Newton's method for sqrt/ln
- Taylor series for exp/sin
- Range reduction (exp: eˣ = 2ᵏ·eʳ, sin: quadrant mapping)
Error bound: |error| < 2^(-16) ≈ 1.5 × 10^(-5)
References:
- SilverSight.FixedPoint.Q16_16 (integer implementations)
- No Float in compute paths (all delegations to FixedPoint or precomputed constants)
Part of the OTOM TreeDIAT/PIST family.

SieveLemmas.lean -- Number-theoretic lemmas for coprime sieve observers
This module formalizes the CRT reconstruction principle referenced in
ImaginarySemanticTime.lean: two observers with coprime native sieve moduli
hold independent, complementary shadows of the same underlying manifold
coordinate. Neither observer can recover the other's view without a CRT
exchange, but together they reconstruct the coordinate modulo the product.
Key lemma: depth_token_coprime_intersect — the observations of two coprime
sieves intersect in exactly one residue class modulo ℓ₁·ℓ₂, which is the
original semantic coordinate's residue class.

-- AVM ISA v1 — Goal A: run a canary, construct an RRC record, emit JSON.
--
-- This module is the first end-to-end connection between:
-- AVMIsa.Run (fuel-bounded execution, Outcome State)
-- ReceiptCore (receipt ledger, leanBuildReceipt, hasProofReceipt)
-- RRCLogogramProjection (projection/merge admission gates, LogogramReceipt)
--
-- The #eval at the bottom is the "rainbow raccoon compiler" proof-of-life:
-- it runs the boolean-not canary through the AVM, checks the result, mints
-- a receipt, gates it through the RRC projection discipline, and prints the
-- whole bundle as a JSON string that a Python harness can validate.

-- This module ports the core decision logic of rrc_pist_shape_alignment.py
-- into Lean. It is the first step toward a Lean-only RRC compiler that can
-- replace shim-space Python for all admissibility and routing decisions.
--
-- Shim contract (mirrors rrc_pist_shape_alignment.py):
-- - promotion is always not_promoted at this stage
-- - all alignment/gating decisions happen in Lean, not in Python
-- - output is a JSON string that the Python harness can validate
-- - claim boundary: admissibility + routing pass only; not a proof of
-- the underlying mathematics

# Rainbow Raccoon Compiler Logogram Projection
This module formalizes the small claim proven by the current Python receipt:
* a logogram can be type-admissible as a `LogogramProjection`;
* a torn logogram can be projection-admissible after repair/quarantine;
* the same torn logogram is not merge-admissible.
This is intentionally not a proof that the source mathematics is true. It is a
proof that the routing discipline separates type admission, projection
admission, and merge admission.

- FixedPoint.lean: Q0_64 for receipt scoring
- SyntheticGeneticCoding.lean: AuthorityState alignment (HOLD / REVIEWED)
- SilverSight.Core: bridge to the SilverSight core receipt format
