# GAL-FINGERPRINT-I Chamber v0.2.2 — Gate C finalization path repair

## Defect

Gate C v0.2.1 correctly checkpointed all 121 deterministic-thinning profiles, but attempted to write long loose export filenames directly under an already deeply nested Windows project path. The resulting paths reached 289–345 characters. Windows raised a filesystem `FileNotFoundError`, and the API incorrectly presented that error as `Unknown run`.

## Repair

- All loose JSON, CSV, manifest, and record artifacts are assembled under the short runtime run folder.
- They are packaged into one complete ZIP under the short runtime path.
- Only a compact outer ZIP name is copied to the canonical branch export folder.
- Gate C ZIP-aware readiness and analysis continue to read the complete package without extraction.
- Finalization failures retain `AWAITING_FINALIZATION` and report the real error; they are no longer relabelled as an unknown run.
- Export provenance distinguishes the controller that executed the measurements from the version that finalized the package.

## Scientific impact

The STRUC-I v1.0.4 JavaScript kernel, registered branch definitions, 2,000 Monte Carlo trials per κ, all 121 deterministic-thinning checkpoints, and all Gate C analysis rules are unchanged.

## v0.3 project interpretation

This document contributes to the galaxy structural-fingerprint programme. Numerical, technical, protocol, or provenance content above is preserved. The canonical interpretation is that the fingerprints are reproducible, organized, and galaxy-specific; sampling, coverage, and baryonic-preparation dependence describe the transformation of fingerprint expression and do not erase the structural finding.
