# File guide and reading routes

## For a mathematical reader

1. Read the root card and `CLAIMS_AND_SCOPE.md` to identify the exact endpoint problem and remaining gaps.
2. Read the manuscript abstract and introduction, then the elementary depth argument and universal metric limit.
3. For the v9 focus, read `noncentral_synthesis.tex`, `normal_holonomy.tex`, `regular_synthesis.tex`, and `orbitopic_synthesis.tex` in `SANCTUM-0/tex/`.
4. Compare R101–R108 in `SANCTUM-0/theorem_status.json` with the linked proof labels and audit files.
5. Review the claimed physical recovery separately from the auxiliary source computations.

## For a computational reader

| File or folder | Role |
|---|---|
| `SANCTUM-0/pyproject.toml` | Package metadata; experiments dependency extra |
| `SANCTUM-0/src/caelq_sig/tensor.py` and `lie.py` | Exact tensor/Lie arithmetic |
| `SANCTUM-0/src/caelq_sig/noncentral_carrier.py` | Rational source certificates and optional complete tensor development |
| `SANCTUM-0/src/caelq_sig/polynomial_curvature.py` | Exact Bernstein/Taylor curvature certificate |
| `SANCTUM-0/examples/verify_noncentral_carrier.py` | Both rational candidates; actual flags documented in reproduction guide |
| `SANCTUM-0/experiments/circle13_audit.py` | Symbolic restricted rank-13 audit |
| `SANCTUM-0/tests/` | Existing implementation tests |
| `SANCTUM-0/data/` | Exact certificates, numerical diagnostics, historical execution receipts |

The core uses exact rational arithmetic where declared. Lengths can involve radicals and rational enclosures. Numerical displays should be interpreted using their parent certificate or analytic proof.

## Important version-9 data

| Path under `SANCTUM-0/data/` | Interpretation |
|---|---|
| `rational_noncentral_carrier_v9_75.json` | Fixed rational 75-lower-edge source candidate |
| `rational_noncentral_carrier_v9_147.json` | Fixed rational strongest source candidate |
| `noncentral_carrier_v9_full_tensor_75.json` | Retained full 300-control endpoint execution receipt |
| `noncentral_carrier_v9_full_tensor_147.json` | Retained full 588-control endpoint execution receipt |
| `noncentral_carrier_v9_verification.json` | Source/moment/cost certificate results |
| `unit_test_log_v9.txt` | Original v9 test transcript |
| `unit_test_verification_v9.json` | Original frozen test verification record |
| `static_verification_v9.json` | Original source/label/registry static checks |
| `v9_numerical_search_status.json` | Local search diagnostics, including failed/infeasible runs |

The original verification and implementation reports give additional context for these execution receipts and their runtimes.

## Audits and provenance

`SANCTUM-0/docs/` preserves named historical audits from several versions. Their version labels and old working-directory paths are historical evidence, not instructions to access those paths now. References to other experimental research describe provenance; those archives are not execution dependencies.

`provenance/` holds this preparation's fresh computational receipt, the original manifest/README, exact comparison data, and an inventory. `original/` contains the unchanged input ZIP. Its internal duplicate case variants are intentionally retained inside the immutable ZIP; use the clean `SANCTUM-0/` folder for cross-platform work.
