vh 8f81d8f9d0 memory: no fleetwide notice for U4, and the measurement caveat it creates

Operator decision 2026-09-22: no broadcast to the 17 consuming handles. Same
posture as U5 — adoption gets told apart from design because nobody was primed.

The consequence is a measurement one and it needed writing down before it was
lost. U4's two halves have different adoption costs: the hold rides for free
(a session runs `booth ask` and its booth is held, knowing nothing), but NOT
pressing `keep` has to be learned. So a flat `.forever` rate on 2026-10-06 is
exactly what 'the mechanism works and nobody was told' looks like, and reading
it as a falsification would retire a correct diagnosis on an uncontrolled
measurement.

Records the three counts to report instead, and states the sensitivity floor:
only 4 of 24 booths carry marks at all, so the hold can touch at most a sixth
of the fleet and an effect below one or two booths is not resolvable.

Raw Blame History

Persistent memory — booth

Last updated: 2026-09-22

Always check for /tmp/booth-dev-handoff.md — if it exists and its Written: stamp is under 8 hours old, read it (it carries the in-flight handoff from the previous session), then delete it. Older than 8 hours: stale — delete it unread.

Repo purpose

The Booth is the fleet's operator-review surface: agents post work by making a folder under ~/booth-data, the operator looks at it and judges it in the browser, and the judgment gets back to the agent that posted it. It was built as a file-shuttle and is being converged, unit by unit, onto the review loop it turned out to actually be.

Current state / in-flight

As of 2026-09-22:

v1 is gated on seven units in ROADMAP.md, dependency-ordered U1 → U2 → {U3, U4, U5} → U7, with U6 independent.
U1, U2, U4 and U5 are landed. U1 ce598b3; U2 c7f9437 → v0.2.0, 5e41108 → v0.2.1, 026a1fc → v0.2.2; U5 c015a91 + 95beede → v0.3.0. U4 landed 2026-09-22 — 396 tests green (341 → 396), deployed and verified live, 24/24 booth pages 200, layout probe clean.
U4 released as v0.4.0 (operator approved the minor on 2026-09-22). c3a97c1 is the unit; the release commit carries the pre-existing fixes the bug-hunt panel surfaced in touched files. The tag waited for the last gate to close, per the v0.2.0 lesson — see Tried and abandoned.
⚠ The 17 consuming handles are NOT being told that keep no longer means "waiting on an answer" — operator decision, 2026-09-22, no broadcast. This is deliberate and it CHANGES HOW THE 2026-10-06 RE-COUNT READS: the hold rides for free, but not-pressing-keep has to be learned, so a flat .forever rate does not falsify anything. Read its entry before measuring.
THE NEXT UNIT IS THE OPERATOR'S CALL. U3 (declared embed seam) and U6 (benches) are both unblocked; U7 waits on the rest. U6 is independent of everything and was conceptually unblocked by U5 giving job 5 a home; U3 is where verbatim-booth provenance was deferred to, and U4 added a fourth reason to want it — a verbatim booth has no Booth-rendered header, so its lifetime line lives only on the index card and the marks page.
No gate is outstanding. All three ran on U4 and were folded in: the /heid-contract-review panel (01M34VX0SH23Y3VC92E7GM4S70), the /heid-code-review panel (01M34WAFJC3RTERFYBBZJN1SVG) and the /heid-bug-hunt (01M34Y2R0RAJRSN36Q8K4KAB36). All loops closed with heid. The U5 round's three are also closed (01M340PNVRS21HPASZT38PXQPN, 01M341E9XAPZEFBSPK9HPGAM0S, 01M343SXX27Z47C3STXXRC7M42).
Two dated predictions are pending and must not be forgotten. U5's adoption re-measure on 2026-09-29 (two counts, see its entry — already at 3 of 24 announced and 2 with a why, all from peers told nothing), and the .forever re-count on or after 2026-10-06, a fortnight after U4 landed, which is U4's success criterion. ⚠ Only 4 booths carry marks at all, so the hold's live blast radius is small and the prediction rests on both halves of U4 — see its entry for what a null result would and would not mean.
Three methodology proposals from this session sit with the operator, routed by heid rather than decided unilaterally: reshaping the paraphrase gate toward a drift-check for narrative-heavy contracts, a standing "green-tests-prove-nothing" direction for the code-review gate, and regin's table-vs-signature consistency pass. They are changes to the /heid* skills, not to this repo.
The booth set churns hard: 26 → 24 during this session as the sweeper ran. Re-count rather than trusting any number written here.
