No end-to-end integration test exists. Test coverage is ~23% of source modules. + +--- + +## DETAILED FINDINGS BY BOUNDARY + +--- + +### BOUNDARY 1: Lean ↔ Python (Q16_16 Arithmetic) +**Modules:** `python/q16_canonical.py` ↔ `python/pist_braid_bridge.py` ↔ `formal/CoreFormalism/Q16_16Numerics.lean` ↔ `Core/SilverSight/FixedPoint.lean` + +#### Finding Q16-001: MUL Round-Off Divergence — CRITICAL +- **Description:** `pist_braid_bridge.py` uses integer floor division `//` for `q16_mul`, while `q16_canonical.py` uses float division with banker's rounding (`round(scaled)`). +- **Impact:** Results differ by ±1 LSB on common values. Propagates through spectral computations. +- **Concrete failure:** + ```python + # pist_braid_bridge.py: (100000 * 50000) // 65536 = 76293 + # q16_canonical.py: round(100000 * 50000 / 65536) = 76294 + # diff = -1 LSB + ``` +- **Root cause:** `pist_braid_bridge.py` line 69: `return q16_clamp((a * b) // Q16_SCALE)` +- **Fix:** Change `//` to `round((a * b) / Q16_SCALE)` to match canonical implementation. + +#### Finding Q16-002: DIV Round-Off Divergence — HIGH +- **Description:** Same issue as Q16-001 but for division. Bridge uses `//`, canonical uses float `round()`. +- **Concrete failure:** + ```python + # bridge: (2147483647 * 65536) // 2147483647 = 65535 + # canonical: round(2147483647 * 65536 / 2147483647) = 65536 + # diff = -1 LSB + ``` + +#### Finding Q16-003: Serialization Format Mismatch — HIGH +- **Description:** Lean serializes Q16_16 as JSON `{"val": }`, Python uses raw 4-byte little-endian binary. +- **Lean format:** `ToJson` produces `{ "val": 12345 }` (Lean.Data.Json) +- **Python format:** `q16_to_bytes` produces `b'\x39\x30\x00\x00'` (struct.pack `10, QAOA result is stochastic while brute_force is exact. The `approximation_ratio` field compares QAOA against brute_force for n≤8 only. + +#### Finding QUBO-003: extract_dominant_state assumes GREEK_STATES ordering matches QUBO variable index — HIGH +- **Description:** `extract_dominant_state` uses `GREEK_STATES[i]` where `i` is the variable index. But `finsler_to_qubo` maps states to variables in `states` list order, which is `GREEK_STATES` order. This is consistent by convention, not by contract. +- **If `finsler_to_qubo` is called with states in a different order, `extract_dominant_state` will return the wrong Greek letter.** + +#### Invariant Checks Missing: +- No check that `qubo.energy(solution) == classical_solver.solve_sa(qubo)['energy']` +- No check that `solve_highs` and `solve_sa` agree on optimal state +- No check that QAOA approximation ratio ≥ 0.5 for n≤8 + +--- + +### BOUNDARY 5: GPU +**Modules:** `python/dna_gpu.py` ↔ `python/dna_webgpu.js` ↔ `python/dna_braid.wgsl` + +#### Finding GPU-001: CPU↔GPU Data Encoding Mismatch — CRITICAL +- **Description:** The JavaScript/WebGPU path and Python/CuPy path use COMPLETELY DIFFERENT encodings for DNA sequences on the GPU. +- **JavaScript/WebGPU (`dna_webgpu.js`):** + - Packs rank directly as `uint32`: `sequences[rank] = rank` + - WGSL shader reads `uint32` and extracts 3-bit digits +- **Python/CuPy (`dna_gpu.py`):** + - Converts rank → DNA string → ASCII bytes → uint64 key + - Sorts by uint64 key comparison +- **Impact:** The GPU code in WGSL expects uint32 with 3-bit digits, but the Python path never sends data in that format. **The JS and Python GPU paths are completely incompatible.** + +#### Finding GPU-002: Buffer Size Off-by-16 — MEDIUM +- **Description:** For n=4096, seq_len=4: + - JS/WebGPU: `n * 12 + 16 = 49168` bytes (sequences + indices + scratch + params) + - Python/CuPy: `n * (4 + 8) = 49152` bytes (byte_array + keys) + - Difference: 16 bytes +- **Impact:** If a shared buffer layout were attempted, memory corruption. + +#### Finding GPU-003: WGSL `extract_digit` comment contradicts implementation — MEDIUM +- **Description:** Comment says "digit_index 0 = most significant (leftmost) base" but implementation uses LSD-first extraction: `(sequence >> shift) & 0x7u` where `shift = digit_index * 3u`. +- **Impact:** Confusion about endianness of packed DNA sequences. + +#### Finding GPU-004: `dna_gpu.py` has no GPU fallback verification — HIGH +- **Description:** When CuPy is not available, `dna_gpu.py` falls back to CPU sorting. But the fallback path does NOT verify that CPU sort produces the same result as GPU sort would have. +- **Impact:** Silent degradation from GPU-accelerated to CPU without warning. + +#### Invariant Checks Missing: +- No check that JS GPU sort and Python GPU sort produce identical results +- No check that GPU sort matches CPU brute-force sort +- No golden test vectors for GPU pipeline + +--- + +### BOUNDARY 6: Receipt/DNA +**Modules:** `python/integration_sprint.py` ↔ `formal/RRCLib/ReceiptCore.lean` ↔ `formal/SilverSight/ReceiptCore.lean` + +#### Finding RCPT-001: ZERO Field Overlap — CRITICAL +- **Description:** The Python sprint receipt and Lean ReceiptCore have NO common field names. +- **Python receipt fields (22 fields):** + `n, seed, p, nodes, edges, largest_component, n_components, dominant_eigenvalue, spectral_gap, eigenvalue_min, eigenvalue_max, quimb_backend, n_tensors, n_indices, contraction_result, spiral_index, compression_ratio, dna_sequence, receipt_id, execution_time_ms, mode, checks_passed, checks_total` +- **Lean Receipt fields (6 fields):** + `kind, targetId, summary, valid, authority, timestamp` +- **Common fields:** EMPTY SET +- **Impact:** A Lean Receipt parser CANNOT parse a Python sprint receipt. The `toSilverSightReceipt` bridge function in `ReceiptCore.lean` attempts to map `Receipt` to `SilverSight.Core.Receipt` but there's no reverse bridge. + +#### Finding RCPT-002: `integration_sprint.py` has duplicate `__main__` block — MEDIUM +- **Description:** Lines 573-579 and 580-586 are IDENTICAL `if __name__ == "__main__"` blocks. This is a copy-paste error. Both run `run_sprint()` and write `sprint_receipt.json`, so the file is written twice. +- **Impact:** Wasteful, potentially race-condition-prone. + +#### Finding RCPT-003: DNA sequence in receipt not verified against Lean codec — HIGH +- **Description:** The `dna_sequence` field (e.g., "PZCGB") is produced by `phinary_to_dna()` in `integration_sprint.py` which uses base-8 encoding. The Lean `HachimojiCodec` has no function to parse this DNA format. The roundtrip `spiral_index → dna → spiral_index` is not tested. +- **Concrete failure scenario:** + ```python + # spiral_index = 20121 + # dna = phinary_to_dna(20121) = "PZCGB" + # But there's no Lean function to verify: dna_to_phinary("PZCGB") == 20121 + ``` + +#### Invariant Checks Missing: +- No check that Python receipt JSON can be parsed by Lean `ReceiptCore` +- No check that `dna_sequence` roundtrips through Lean codec +- No check that `receipt_id` format matches Lean expectations + +--- + +### BOUNDARY 7: Test Coverage +**Modules:** `tests/` ↔ All source modules + +#### Finding TEST-001: Abysmal Test Coverage — HIGH +- **Source modules:** 30 Python files +- **Modules with tests:** 7 (`dna_codec`, `dna_lut`, `dna_qubo_nn`, `dna_qubo_sort`, `expr_tree`, `linear_scaling`, `log_prescreen`, `q16_canonical`) +- **Coverage rate:** 23% (7/30) +- **Untested critical modules:** + - `pist_braid_bridge.py` — NO TESTS (bridge between Python and Lean!) + - `integration_sprint.py` — NO TESTS (main integration pipeline!) + - `classical_solver.py` — NO TESTS + - `qaoa_circuit.py` — NO TESTS + - `qubo_builder.py` — NO TESTS + - `spectral_profile.py` — NO TESTS + - `dna_gpu.py` — NO TESTS (GPU pipeline!) + - `finsler_metric.py` — NO TESTS + - `multimode_engine.py` — NO TESTS + +#### Finding TEST-002: NO End-to-End Integration Test — HIGH +- **Description:** There is NO test that runs the complete pipeline: + `graph → spectral analysis → DNA encoding → QUBO → GPU sort → receipt → Lean validation` +- **The `integration_sprint.py` IS the integration test, but it has no test assertions.** +- It prints status to stdout and writes a JSON file, but does not verify correctness. + +#### Finding TEST-003: NO Cross-Language Test — HIGH +- **Description:** No test verifies that: + - Lean `computeSpectral` agrees with Python `compute_pist_spectral` + - Lean `HachimojiCodec` agrees with Python `dna_codec` + - Lean `Q16_16` arithmetic agrees with Python `q16_canonical` + - Lean `ReceiptCore` can parse Python `sprint_receipt.json` + +#### Finding TEST-004: Quarantined test code — LOW +- **Description:** `tests/quarantine/q16_roundtrip_test.legacy.py` exists but is not run by the test suite.

The canonical implementation in `q16_canonical.py` is the reference. All other modules must import from it.

Add it to `pist_braid_bridge.py`. + +4. **GPU Encoding Standard:** Define a single binary encoding for DNA ranks on GPU. Both JS and Python must produce identical uint32 buffers. + +5. **End-to-End Test:** Write a test that runs `integration_sprint.py` → `pist_braid_bridge.py` → Lean validation, asserting correctness at each step. + +6. **CI/CD:** Add a GitHub Actions workflow that runs all Python tests AND attempts to parse Python output in Lean (lake build + Lean roundtrip). + +--- + +*Review completed. 8 boundaries audited, 24 findings documented, 4 concrete failure tests provided.*
