Description

_constitution_provenance_matches_preset() already treats missing, invalid JSON, and undecodable provenance as a non-match, but an OSError while reading the same metadata escapes and can interrupt preset handling.

This fails closed for read errors as well: unreadable provenance never authorizes a preset match.

Testing

  • Tested locally with uv run specify --help
  • Ran existing tests with uv sync && uv run pytest (6,652 passed, 177 skipped)
  • Added a direct unreadable-provenance regression using a targeted Path.read_text failure
  • uvx ruff@0.15.0 check src tests clean

Implemented autonomously by GitHub Copilot CLI (model: GPT-5.6 Sol) under human direction; a failing regression was added before the fix, then the full suite and lint were run locally. Commit includes Assisted-by and Co-authored-by trailers.
