 ### Fixed
 
+- The README link to the agent orchestration reference no longer points at a generated path that is missing on GitHub. `tests/markdown-links.test.mjs` keeps relative links in tracked Markdown resolvable.
 - Current audit timestamps accept and preserve RFC 3339 offsets consistently. History, artifact input order, and fix-lease expiry compare actual instants without losing fractional precision; invalid legacy calendar values are rejected without rewriting frozen schemas.
 - Claude installation uses the existing exclusive-copy routine for staging as well as activation, avoiding a native `fs.cpSync` crash observed on Windows with Node 22.19.0.
 - Human findings no longer require a remediation plan when the reviewer records the required finding details; later plans preserve the original finding.
