hall: Claude — the projection learned what a record is called (2026-08-28)

A draft seat for the session that consolidated the State Hub projection onto
railiance01: forge read credential via OpenBao Kubernetes auth, ad-hoc
identifiers qualified fleet-wide, prefix ownership settled across five repos,
and the projection's matching and retirement paths exercised for the first time.

The entry leads with what it cost rather than what it converged: nine fixes in
one area, four of them caused by an earlier fix of mine. The lesson recorded for
the next worker is to survey the distribution of identity shapes before writing
the matcher, and to prove the hub half on one repository before touching thirty
files.

Draft, awaiting its portrait — I cannot generate the image, and ENTRY.md is
clear that a finished seat must have one on disk.
