vh c5ac49356f memory: snapshot — U6 released at v0.6.0, six of seven v1 units landed
Nothing in flight. The in-flight section is rewritten to the post-release
state and carries the five things a fresh session must not do: push (main is 8
ahead of origin/main), seed the registry, send the 17-handle note, run either
dated prediction early, or start U7 without re-counting the booths first.

Two new detail files: the release itself, and what each of the five review
passes could only see alone -- the strongest evidence this repo has for running
all of them rather than picking one. The earlier U6 entry is reconciled; it was
written while the gates were still out and said NOT TAGGED.

Restored in the rewrite: the warning that the 17 handles were never told `keep`
stopped meaning "waiting on an answer", which is load-bearing for how the
2026-10-06 re-count reads, and the fact that a remote now exists.

# Persistent memory — booth

## 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:_
- **NOTHING IS IN FLIGHT.** U6 (benches) landed, all four review gates closed,
**released as `v0.6.0`** and deployed. Tree clean at `3296a86`, 607 tests
green, 19/19 booths 200 live. ⚠ **NOT PUSHED** — push is the operator's call
and he did not give it this session; `main` is ahead of `origin/main`.
→ `persistent-memory.d/2026-09-22-u6-benches-released.md`
- **v1 is gated on seven units. SIX ARE LANDED. U7 IS THE LAST ONE.** U1
`ce598b3`; U2 → `v0.2.0`/`v0.2.1`/`v0.2.2`; U5 → `v0.3.0`; U4 → `v0.4.0`;
U3 → `v0.5.0`; U6 `1c3ce5d` → `v0.6.0`.
- ⚠ **Before starting U7, read
`persistent-memory.d/2026-09-21-u7-section-premise-half-wrong.md` AND
re-count the booths first.** Its premise has degraded twice over: every booth
that needs navigation is FLAT, and on 2026-09-22 the four large booths it was
sized against (`pancake-v3-full`/`pancake-v4-full` at 270 items,
`sindra20-engines`, `sindra-finalists`) had ALL been swept. Largest live booth
is `miranda-is` at 92 items. Two of 19 booths have subfolders and both are
reports. Sections buy close to nothing; the rail, filters and grid keyboard
are the unit.
- ⚠ **ONE DEFECT IS OPEN, AND THE OPERATOR HAS NOW BEEN ASKED TWICE.** A
`.marks.json` that is well-formed JSON with a wrong-shaped `answer` 500s **the
gallery page and the marks page**. Predates U3 (measured at `42ea67f`). No
issue, no tracking surface — untracked by operator choice. Session
recommendation is `_hydrate` (one predicate, one place, every surface
inherits it). Read
`persistent-memory.d/2026-09-22-a-wrong-shaped-answer-500s-the-gallery.md`
before touching marks rendering anywhere.
- ⚠ **TWO OPERATOR DECISIONS ARE OUTSTANDING AND BOTH ARE DELIBERATELY NOT
DONE.** (1) The single althing note to the 17 handles about `booth link`
refusing booth URLs — gated as multi-recipient, drafted nowhere, NOT SENT.
(2) Seeding the bench registry from the board — he said "no seeding yet", so
`booth bench import --apply` has NOT been run against live data and
`.benches.json` does not exist in `~/booth-data`.
- ⚠ **THE 17 CONSUMING HANDLES WERE NEVER TOLD that `keep` stopped meaning
"waiting on an answer"** — operator decision 2026-09-22, no broadcast, and it
still stands. **This 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 the diagnosis. Read its entry before measuring.
- **A remote exists and `main` is AHEAD of it.** `origin` is
`git@gitea.phasefinal.com:vh/booth.git`; the first push of this repo's history
was 2026-09-22 (26 commits, `v0.2.0`–`v0.5.0` in one motion). As of this
snapshot `main` is **8 commits ahead of `origin/main`** — the whole of U6
including `v0.6.0`. Pushing is the operator's call.
- **Two dated predictions are pending and must not be run early.** U5's adoption
re-measure on **2026-09-29**; the `.forever` re-count **on or after
2026-10-06**. Before the second, read
`persistent-memory.d/2026-09-22-no-notice-and-what-it-does-to-the-prediction.md`.
- **FIVE methodology proposals sit with the operator, untracked by his choice**
— four from earlier rounds plus Kimi's new one: promote "the falsifiable test
is weaker than the invariant it guards" to its own ambiguity class in
`/heid-contract-review`. It now has two data points in this repo (five of
seven U4 falsifiers vacuous; U6 shipped a tie-break falsifier that could not
fail). They are `/heid*` skill changes, not this repo's work.
- The booth set churns hard: 26 → 24 → 25 → 23 → **19** across five sessions.
Re-count rather than trusting any number written here.
