 ### Fixed
 
+- Documentation a reader could not follow. 98 curl examples single-quoted
+  `$TOKEN`, so the shell never expanded it and the server answered 422; a JSON
+  body carried a `//` comment, which made the server report a missing hostname
+  about a body that has one; the IIS install omitted `flask plugin upgrade-all`,
+  which is the 1054 error a deploy hits days later; a pilot loop exited 1 on
+  every iteration; and the external-plugin guide pinned a contract version six
+  releases stale, so a plugin built by following it is refused at startup. Nine
+  documents now point at the generated project map rather than typing a version,
+  and a test enforces that. The API inventory gained the 22 routes that were
+  serving traffic undocumented, with a parity test against the live URL map so
+  the next one cannot slip in silently.

 - **Every plugin migration chain re-ran its head on each MySQL deploy.** Core's
   Alembic env got a `connection.commit()`; the per-plugin template did not, so
   the last migration of every run lost its version stamp while its DDL survived.
