A controller restart lost every call's outcome, `status` composed the mesh
while its caller waited (18.6s live on 2026-10-06, past the 10s window), a
repair by hand left no trace, and the core's bounds had nothing measured to
be set from.
- calls: kept in the controller's bucket mesh-controller_calls (last 1000 or
14 days, answers bounded to 64 KiB), read by id across a restart; a
controller starting marks a stopped one's running calls abandoned; each
call names its caller from the inbox its answer goes to.
- status: the serving controller composes it at start, after news from a
machine, a build or an acting verb, and every minute; the verb answers the
last composition at once with when and how long it took. Composing resolves
each machine once instead of twice.
- hand-act log in mesh-controller_hand-acts: push (required through the seat),
plans stop/close, broker consumer-reset and the new hand-act record take
--why/--cause/--condition; `hand-acts` lists them and repeated causes;
status counts the week's.
- durations (migration 0066): apply (send to first report), heartbeat gap,
plan tier and build, recorded as heard; `durations` summarises them.
- the controller's seat row takes this binary's definition of its own verbs,
so the console no longer judges calls against an older build's schema.
- the controller is granted its two buckets' subjects.
Phase 1 made the set data; a rename still broke every reference to the old
name. This adds the stable identity: a seat's canonical name changes and its
old name becomes an alias that resolves to it forever. SeatNamed and the holder
and display matching resolve a name (former or current) to its seat, so a
manifest's claim, a held record, the git-seat lookup and the build machine's
embedded set all go on working unchanged after a rename. seat_alias table
(migration 0035), inventory Aliases/RenameSeat, openInventory loads them, and a
'seat rename <from> <to>' command does the whole thing — one operation, no
rebuild, no re-registration, no freeze. Behaviour-neutral until a seat is
renamed. Validated against postgres.
The seat set was a Go slice compiled into the controller and referenced by
name everywhere, so changing it meant a rebuild and a freeze-prone deploy. It
is now a table: catalogue keeps the shipped set as defaultSeats (the seed and
the fallback) and a loadable working set; inventory adds the seat table
(migration 0034), Seats to read it, and SeedSeats to fill it idempotently
without overwriting an operator's edit; migrate seeds it; openInventory loads
it, and an empty or unreadable table leaves the compiled defaults in force so
it can never brick the control plane's boot.
Behaviour-neutral: the seeded table equals the defaults. Phase 2 (reference by
a stable id so a rename touches no manifest or code, and the builder reads the
set from the mesh) follows.
