⚠ BREAKING CHANGES

• caching: key on the request, not on the machine (#26)
• caching: exec provider and exec grader cache entries are re-keyed by the switch from mtime to content digests. Existing entries are not served and will age out; no action is needed beyond expecting one cold run per suite. Network providers are unaffected.

Features

• caching: key exec identity on content, correct the cache_salt docs (#24) (80479dc)

• server: authenticated MCP endpoint, dual-era and read-only (#27) (88739d3)
