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:

• U6 SHIPPED (v0.6.0) with a late fix (v0.6.1). PUSHED. main and both tags are on origin as of 2026-09-22 — the tree is no longer single-copy. → persistent-memory.d/2026-09-22-u6-benches-released.md
• THE OPERATOR RULED ON EVERYTHING OUTSTANDING (2026-09-22, "accept all recs"). Four of five settled and executed; one blocked by the permission layer. Nothing is waiting on him. → persistent-memory.d/2026-09-22-operator-ruled-on-the-open-five.md
• U7 IS THE ONLY WORK LEFT, AND IT IS NOW UNBLOCKED. The three ratified components (rail, filters, grid keyboard) are landed at a306e2d. The fourth — filename-prefix groups replacing subfolder sections — is APPROVED and NOT yet built. That is the next session's first job. → persistent-memory.d/2026-09-22-u7-three-quarters-and-one-ruling.md
• ⚠ tests/test_navigation.py::test_no_group_rail_is_shipped_yet IS NOW A STALE GUARD. It exists to stop an UNAPPROVED group rail; the rail is approved, so whoever builds it must DELETE that test in the same commit. It will otherwise read as a real invariant and block correct work.
• 623 tests green. Tree clean and pushed. Deployed; 19/19 booths 200.
• 🛑 STANDING RULING — NO ANNOUNCEMENTS OUT OF THIS REPO, AND THE OPERATOR SENDS THE EVENTUAL ONE HIMSELF (operator, 2026-09-22). Verbatim: "no announcements until the entire arc is done, and even then i'll do it myself." Two clauses, both binding: (a) no althing announcement of any kind ships from booth-dev until the v1 arc is COMPLETE — not per-unit, not at the 1.0 tag, not "just the peers who consume it"; (b) when the arc IS done, the announcement is HIS to send, not a thing to ask permission for. This is STRICTER than ~/.claude/CLAUDE.md's broadcast gate, which merely requires approval — here the send is not the agent's to make at all, so asking is also out of scope. Do not offer, draft-and-await, or surface it as a pending decision; it is settled and not a standing question. The 17-handle booth link note is consequently REASSIGNED, not blocked. The full draft + recipient list stays at docs/pending/fleet-note-booth-link-refusal.md as MATERIAL FOR HIM. It is no longer an open loop, no longer awaiting approval, and no longer a thing to raise. Same for anything U4's keep-semantics change would have warranted telling peers.
• ⚠ NOT SEEDED, and this survives the blanket ruling. "No seeding yet" was a SPECIFIC prior instruction, not a recommendation of mine, so "accept all recs" does not override it. .benches.json does not exist in ~/booth-data.
• A U7 directive (D-0011) misrouted to infra-ops and is SUPERSEDED. Miranda confirmed directly. Nothing to act on. → persistent-memory.d/2026-09-22-a-directive-misrouted-by-pane-title.md
• ⚠ THE 17 CONSUMING HANDLES WERE NEVER TOLD that keep stopped meaning "waiting on an answer" — and the note above does not tell them either; it is about booth link. This CHANGES HOW THE 2026-10-06 RE-COUNT READS: a flat .forever rate does NOT falsify the diagnosis.
• Two dated predictions pending, not to be run early. U5's adoption re-measure 2026-09-29; the .forever re-count on or after 2026-10-06.
• FIVE /heid* methodology proposals sit with the operator, untracked by his choice.
• The booth set churns hard: 26 → 24 → 25 → 23 → 19. Re-count rather than trusting any number here.

Recent decisions

• [2026-09-22] 🛑 STANDING: no announcements out of this repo until the arc is done, and he sends that one himself — verbatim "no announcements until the entire arc is done, and even then i'll do it myself." Stricter than the house broadcast gate: the send is not the agent's to make, so asking is also out of scope. The drafted 17-handle note is REASSIGNED to him, not blocked — see the in-flight row above; do not raise it again.
• [2026-09-22] The operator ruled on all five open items at once — four executed incl. the first push; the broadcast was blocked by the permission layer and is drafted at docs/pending/ → persistent-memory.d/2026-09-22-operator-ruled-on-the-open-five.md
• [2026-09-22] U7 is three-quarters built and blocked on one word — the ratified three landed; the sections-vs-groups departure is NOT built and is the operator's call, tracked at docs/contracts/u7_navigation.contract.md → persistent-memory.d/2026-09-22-u7-three-quarters-and-one-ruling.md
• [2026-09-22] An approved directive misrouted because pane_find addresses by a rolling pane title — resolved; the MECHANISM is the durable part, reported to infra-ops, untracked by booth-dev → persistent-memory.d/2026-09-22-a-directive-misrouted-by-pane-title.md
• [2026-09-22] U7 re-measured before scoping — sections are dead, filename prefixes are not — PRE-WORK ONLY, no unit started; read before writing U7's contract → persistent-memory.d/2026-09-22-u7-remeasured-before-scoping.md
• [2026-09-22] The last open defect closed, and building its falsifier found another — the wrong-shaped answer fixed at _hydrate; _safe_fragments lost its natural trigger and its handler could not survive the failure it handled → persistent-memory.d/2026-09-22-a-wrong-shaped-answer-500s-the-gallery.md
• [2026-09-22] U6 released as v0.6.0 — benches, and the number that was two defects — six of seven v1 units landed, NOT PUSHED → persistent-memory.d/2026-09-22-u6-benches-released.md
• [2026-09-22] Three cold panels on one unit, and what each lens could only see alone — READ BEFORE DECIDING TO SKIP A GATE; all five passes found something the others structurally could not → persistent-memory.d/2026-09-22-three-cold-panels-on-one-unit.md
• [2026-09-22] U6 landed — three surfaces, three jobs, one predicate — the seam review caught three real contract defects incl. a per-row resolve_booth that would have 404'd the board → persistent-memory.d/2026-09-22-u6-benches-landed.md
• [2026-09-22] The 69% link-board rot was two defects wearing one number — READ BEFORE SCOPING ANY LINK-BOARD WORK; U5 closed the larger half and full-URL-vs-origin identity is a measured call → persistent-memory.d/2026-09-22-one-number-was-two-defects.md
• [2026-09-22] U3 landed — the page declares the seam, the Booth mounts into it — ten regexes against author HTML replaced by a substring test and a + → persistent-memory.d/2026-09-22-u3-declared-embed-seam-landed.md
• [2026-09-22] A wrong-shaped answer 500s the gallery and the marks page — PRE-EXISTING (measured at 42ea67f), NOT U3; the v0.2.2 lesson is only half-implemented → persistent-memory.d/2026-09-22-a-wrong-shaped-answer-500s-the-gallery.md
• [2026-09-22] The browser became a test surface — READ BEFORE TOUCHING playwright IN pyproject; the pinned upper bound is the foot-gun, and these tests SKIP rather than fail → persistent-memory.d/2026-09-22-the-browser-became-a-test-surface.md
• [2026-09-22] A vacuity pass that tries the contract's own mutation agrees with itself — U3 ran one, reported 7/7, and a cold panel then showed one of the seven was vacuous; READ BEFORE WRITING A Falsifiable: LINE → persistent-memory.d/2026-09-22-seven-of-seven-falsifiers.md
• [2026-09-22] U4 landed — lifetime is derived, not declared — three states, viewing is activity, and no new arithmetic anywhere → persistent-memory.d/2026-09-22-u4-derived-lifetime-landed.md
• [2026-09-22] The .forever diagnosis got a live positive control — 3 of the 4 booths awaiting an answer were ALSO hand-pinned — RE-COUNT 2026-10-06 → persistent-memory.d/2026-09-22-forever-had-a-live-positive-control.md
• [2026-09-22] No fleetwide notice for U4, and what that does to the prediction — READ BEFORE THE 2026-10-06 RE-COUNT; a flat rate does not falsify the diagnosis → persistent-memory.d/2026-09-22-no-notice-and-what-it-does-to-the-prediction.md
• [2026-09-22] Four independent paths to one fail-open delete — the bug-hunt panel's class, and the zsh word-splitting trap that shipped an empty bundle → persistent-memory.d/2026-09-22-four-paths-to-one-fail-open-delete.md
• [2026-09-22] Two reads of one file are not one read of one state — a TOCTOU seam that composes two correct readers into a fail-open delete → persistent-memory.d/2026-09-22-two-reads-are-not-one-state.md
• [2026-09-22] Five of seven INV falsifiers did not falsify anything — read before writing a Falsifiable: line; a green test cited one rather than being one → persistent-memory.d/2026-09-22-vacuous-falsifiers.md
• [2026-09-22] The third one-branch template miss — this repo's recurring blind spot; read before adding a fact to any template → persistent-memory.d/2026-09-22-third-one-branch-template-miss.md
• [2026-09-22] The size cap opened a service-wide hang — a FIFO has st_size 0; a bound that trusts it inherits what it does not mean → persistent-memory.d/2026-09-22-size-cap-opened-a-hang.md
• [2026-09-22] An existing test stopped me retiring documented behaviour — the clean fix for the mtime race would have silently changed TTL doctrine → persistent-memory.d/2026-09-22-doctrine-not-defect.md
• [2026-09-22] Two U5 panels, and prose reached a released outage — read the detail before assuming a conformance finding stops at its own module → persistent-memory.d/2026-09-22-u5-panels-reached-a-released-bug.md
• [2026-09-22] U5's adoption prediction split in two — the handle rides for free, the why must be learned — RE-MEASURE 2026-09-29 → persistent-memory.d/2026-09-22-u5-adoption-split-in-two.md
• [2026-09-22] The U2 bug-hunt panel was not ceremony — the lock-unlink race and the TTL guard that was failing at its own job → persistent-memory.d/2026-09-22-u2-bug-hunt-panel.md
• [2026-09-22] The lenient reader's blast radius was the whole service — marks_for runs per booth per index load; a raise there is an outage → persistent-memory.d/2026-09-22-lenient-reader-blast-radius.md
• [2026-09-22] booth marks / booth answer got real exit codes — read it before changing anything the 17 consuming handles call → persistent-memory.d/2026-09-22-cli-exit-codes.md
• [2026-09-22] scripts/booth went from zero tests to five — they run the real script under system python3, so they also check INV-1 → persistent-memory.d/2026-09-22-scripts-booth-got-tests.md
• [2026-09-21] v0.2.0 was tagged while a gate was in flight — the sequencing lesson: if a gate is outstanding, the tag waits → persistent-memory.d/2026-09-21-v020-tagged-with-a-gate-in-flight.md

• [2026-09-21] A partially-answered pick counts as OPEN — declared, not smuggled; it is the reading that makes U4 correct → persistent-memory.d/2026-09-21-partial-answer-counts-as-open.md
• [2026-09-21] The U2 seam review earned its place, and how — inline.place indexes by subscript — the miss a cold panel cannot see → persistent-memory.d/2026-09-21-u2-seam-review-earned-it.md
