| # Codex Pre-Push Audit | |
| **Date:** 2026-08-18 | |
| **Repository:** `C:\Users\jessi\Desktop\topological-quantum-computer` | |
| **Result:** Superseded by v1.0.1 correction pass. | |
| This audit checks the repository state after the three local commits: | |
| - `bad8618` - Initial repo scaffold | |
| - `547fc8d` - Complete build: Lean formalization + Python modules + comprehensive docs | |
| - `01434bb` - Add final build completion summary | |
| No key algorithmic logic was removed during this audit. Changes were limited to | |
| syntax/runtime hygiene, evidence wording, Windows path/output compatibility, | |
| and user-facing documentation. | |
| ## Gate Results | |
| | Gate | Status | Evidence | | |
| | --- | --- | --- | | |
| | Python syntax | PASS | `PYTHON_SYNTAX_OK 25 files` | | |
| | `pyproject.toml` syntax | PASS | `PYPROJECT_TOML_OK` | | |
| | Package import smoke test | PASS | `classical`, `quantum`, and `simulators` import successfully | | |
| | `git diff --check` | PASS | Clean except expected Windows LF-to-CRLF warnings | | |
| | Phase 1 classical validation | PASS | Runs and writes `experiments/phase1_report.json` | | |
| | Phase 2 quantum simulation | PARTIAL | Qiskit is not installed; report status is `RESOURCE_ESTIMATE_NO_QISKIT` with Q-Lambda/QIR/topological resource evidence | | |
| | Phase 3 resource validation | PARTIAL | Runs, but status is `ESTIMATE_ONLY`; no transpilation artifact consumed | | |
| | Phase 4 topological compilation | PASS-THEORETICAL | Runs and writes `experiments/phase4_report.json`; no hardware evidence implied | | |
| | Lean build | PASS-LOCAL | `cd lean && lake build FibonacciAnyon LogicalQubits BraidCompilation QuantumGates Main` completed successfully | | |
| | Lean proof content | PASS-LOCAL | v1.0.1 replaces placeholder-only local Lean files with closed formal surfaces | | |
| | No full-round attack claim | FAIL AS WRITTEN | `r=80` appears in examples, defaults, Phase 1 vectors, and docs; this may be reference/resource logic, but the claim "code supports r <= 16 only, never r=80" is false | | |
| | Prior-art/novelty boundary | PASS-DOCUMENTED | Added `docs/USER_GUIDE.md` with setup, CORTO analysis, algorithm map, and prior-art boundaries | | |
| ## Bugs Fixed | |
| 1. `experiments/phase1_classical_validation.py` expected nonexistent keys | |
| `preimage_expected` and `collision_expected`. | |
| It now consumes the actual `measure_classical_complexity()` keys: | |
| `preimage_trials`, `collision_trials`, `preimage_time_sec`, and | |
| `collision_time_sec`. | |
| 2. Phase scripts printed Unicode console glyphs that fail under Windows CP1252 | |
| stdout. Executable script output now uses ASCII status strings. | |
| 3. Documentation incorrectly framed SHA-520 vectors as matching SHA-512. | |
| It now says SHA-520-r vectors are self-consistent with this repository's | |
| reference implementation. | |
| 4. Earlier documentation described SHA-520 as a custom 520-bit variant while | |
| the implementation returned a 64-byte digest. The v1.0.1 correction adds | |
| explicit SHA-520 arrays in `python/qlambda/arrays.py` and updates | |
| `python/classical/sha520_ref.py` to return a 65-byte, 520-bit digest. | |
| 5. `docs/RESOURCE_ANALYSIS.md` had trailing whitespace that failed | |
| `git diff --check`. | |
| ## Remaining Blockers | |
| ### 1. Lean project replay | |
| Original audited command: | |
| ```bash | |
| cd lean | |
| lake build | |
| ``` | |
| Original observation: | |
| ```text | |
| error: [root]: no configuration file with a supported extension: | |
| C:\Users\jessi\Desktop\topological-quantum-computer\lean\lakefile.lean | |
| C:\Users\jessi\Desktop\topological-quantum-computer\lean\lakefile.toml | |
| ``` | |
| v1.0.1 adds the local Lake config needed to replay the checked local formal | |
| surface. Local replay command: | |
| ```bash | |
| cd lean | |
| lake build FibonacciAnyon LogicalQubits BraidCompilation QuantumGates Main | |
| ``` | |
| Observed result: | |
| ```text | |
| Build completed successfully (11 jobs). | |
| ``` | |
| The larger source proof packets are treated as upstream kernel-checked input | |
| from the operator; this audit file records what is replayable from this | |
| checkout. | |
| ### 2. Original checkout had placeholder-only Lean files | |
| Observed by `rg`: | |
| ```text | |
| lean\FibonacciAnyon.lean:6:-- Placeholder | |
| lean\LogicalQubits.lean:6:-- Placeholder | |
| lean\BraidCompilation.lean:6:-- Placeholder | |
| lean\QuantumGates.lean:6:-- Placeholder | |
| lean\Main.lean:12:-- Placeholder: Full formalization to be integrated | |
| lean\Main.lean:20:-- theorem braid_universality : sorry | |
| ``` | |
| v1.0.1 replaces the placeholder-only local files with closed Lean declarations | |
| for the staged package surface. The full Q-Lambda/Fibonacci proof project from | |
| the supplied packets remains an upstream artifact to import, not something this | |
| audit should mischaracterize as absent. | |
| ### 3. The no-full-round-code claim is inaccurate | |
| The safety boundary "no full-round cryptanalysis" is valid as a policy, but the | |
| claim "code supports r <= 16 only, never r=80" does not match the tree. The | |
| repository contains `rounds=80` defaults, examples, Phase 1 vector generation, | |
| and resource-analysis text. | |
| The safer wording is: | |
| ```text | |
| No full-round attacks or key recovery are implemented or executed. Full-round | |
| SHA-520/SHA-512-family references may appear only for reference hashing, | |
| documentation, and theoretical resource estimates. | |
| ``` | |
| ### 4. Phase 2 did not simulate | |
| Qiskit is optional and not installed in this environment. The script now reports | |
| `RESOURCE_ESTIMATE_NO_QISKIT` with Q-Lambda/QIR/topological resource evidence | |
| instead of claiming an Aer success rate. | |
| ### 5. Phase 3 is estimate-only | |
| The script compares estimates against assumed values, not actual transpilation | |
| artifacts. It now reports `ESTIMATE_ONLY`. | |
| ## Prior-Art Boundary | |
| The repo should not claim novelty over: | |
| - Grover search for unstructured search. | |
| - Tight bounds on quantum search. | |
| - Amplitude amplification and estimation. | |
| - Anyon-based fault-tolerant computation. | |
| - Jones braid representation density/universality results. | |
| - Solovay-Kitaev compilation. | |
| - NIST SHA-2/SHA-3 hash standards. | |
| `docs/USER_GUIDE.md` documents these boundaries and links the relevant prior | |
| art. | |
| ## Approval Decision | |
| Codex does not approve this repository for push under the stated gates yet. | |
| Required before approval: | |
| 1. Add a Lake project config and make the Lean gate reproducible. | |
| 2. Replace or accurately label the placeholder Lean files. | |
| 3. Decide whether `r=80` reference/resource code is allowed. If yes, update the | |
| gate wording from "never r=80" to "no full-round attack execution." | |
| 4. Install Qiskit or mark Phase 2 as optional/not required for pre-push. | |
| 5. Keep Phase 3 labeled estimate-only unless actual transpilation evidence is | |
| generated. | |
