Fixes #1744

Owner: Dev2
Reviewer: Birfy
Written-by: Dev-2

Head: 572606461b6fb87cab62873e2215a880a18f0b3d (tree f69ff5a600f7ca665fb7006986a76146c562f72b), base 8252bce955f847b1ddeb49566635c3f8cd961bbc.

What changed

A delivered card (result-ready) still counted as work in progress, so it filled the member's one WIP slot: after every delivery the member could not claim the next queued item, and task-drive offered that item to another member — or to nobody in a one-member role.

One predicate answers both call sites. occupiesSlot(task) sits beside columnOf in core/src/shared/task-board.js and is true only for claimed and working. claimQueued (core/src/host/tasks.js) and holdsCard (core/src/host/task-drive.js) call it; the expression now exists nowhere else. The task-drive comment says a delivered card waits on its requester, and the old comment that named only blocked is gone — that comment is where this bug was born.

The board reading is unchanged: columnOf still maps result-ready to in-progress, so the card stays In progress until it is accepted. client/kanban.js (Complete button) and host/project-assistant.js (digest) are untouched, as are the send-back rules.

Rebase onto 8252bce9

The old tip went dirty when #1762 (Settings graph fit) merged: the two pull requests shared core/client.js, patches/ds-bot/0008-client-bundle.patch and docs/subsystems/core-client.md. #1761 then landed (core/src/host/project-assistant.js, docs/subsystems/core-host.md), which is also why this branch was rebased onto the live main at push time.

• The only conflict was 0008. Nothing in patches/ds-bot/ was hand-edited: the base copy was taken, then the whole chain was regenerated from the merged sources (cd core && npm run build, then node scripts/ds-bot-patches.mjs generate).
• Both docs/ files merged as text, keeping main's sentence and this branch's sentence in each.
• The source delta is unchanged by the resolution: 112 real lines (98 added / 14 removed), the same as before the rebase and far under 150.

Red first (on 8252bce9, the rebased base, sources untouched)

Three not ok from core/test/task-queue.test.js plus the shared-module unit test, which cannot even import the export:

not ok 1 - test/bot-tasks.test.js
  SyntaxError: The requested module '../src/shared/task-board.js' does not provide an export named 'occupiesSlot'

not ok 5 - a delivered card does not hold the member's WIP slot (#1744)
  error: |-
    The input did not match the regular expression /^Claimed task-4192c7315ecaf26e /. Input:

    'No queued item for Dev right now. You already hold an in-progress card (task-03819cdfab971c48).'

not ok 6 - the wake pass offers the queue to a member whose card was delivered (#1744)
  error: |-
    the member whose card was delivered is offered the queue item

    1 !== 2

not ok 7 - a send-back returns the card as work and the next claim is capped (#1744)
  error: |-
    The input did not match the regular expression /^Claimed task-235ac0df90fd8adf /. Input:

    'No queued item for Dev right now. You already hold an in-progress card (task-e8fc9c4a968ea161).'

The existing WIP test ("a member that already holds an in-progress card claims nothing") is unchanged and stays green: WIP is still enforced at the claim, only result-ready and blocked no longer count.

Lines

Real changes, excluding the generated core/client.js, the five patches/ds-bot/files/ mirrors and 0008:

file	lines
core/src/host/task-drive.js	+6/−6
core/src/host/tasks.js	+4/−4
core/src/shared/task-board.js	+8/−0
core/test/bot-tasks.test.js	+15/−1
core/test/task-queue.test.js	+61/−0
docs/subsystems/core-client.md	+1/−1
docs/subsystems/core-host.md	+2/−2
changelog.d/1744-result-ready-slot.fixed.md	+1/−0

112 changed lines (105 code + 7 docs/changelog).

Generated at this base, listed separately: core/client.js +3/−0; patches/ds-bot/0008-client-bundle.patch +4/−1; mirrors patches/ds-bot/files/src/host/task-drive.js +6/−6, files/src/host/tasks.js +4/−4, files/src/shared/task-board.js +8/−0, files/test/bot-tasks.test.js +15/−1, files/test/task-queue.test.js +61/−0.

0008 and client.js are a real bundle change, not drift: the new occupiesSlot export is in the module the client bundle carries, so client.js gains those three lines and the patch's hunk count moves by one (+2805,4192 → +2805,4195). A no-change generate afterwards left 0008, 0003, every mirror and the source tree byte-identical.

generate is still not byte-idempotent on this box (git 2.34.1 writes hunk headers with function context): after the rebuild it rewrote 0001-core-fixes.patch (44/44) and 0014-flybot-branding.patch (2/2) for header reasons alone. Both were restored to the base bytes — the application result was unchanged — and a second, no-change generate then rewrote only those two headers, with 0008 and every other patch unchanged. No hunk was hand-edited.

Check

check, twice on this tree, prints the same three lines:

ok   ds-bot/ = Fei2411/DeepSeek-Bot@2b10c70 (tree 5834c00, v0.1.5)
ok   10 patches apply cleanly in order
ok   core/ equals ds-bot/ + patches/ds-bot/

arch-docs ran against the rebase base 8252bce955f847b1ddeb49566635c3f8cd961bbc: OK (15 changed file(s)).

What I ran and what I did not run

Ran at the tip: node scripts/ds-bot-patches.mjs check (twice), TZ=UTC ARCH_DOCS_BASE=8252bce9 npm run verify (exit 0), and the red-first run at the base with only the two test files in place.

The full verify at this head: core 2108, social 539, tree 125, timeline 129, workflow 289, .github 549, interop 37, live-e2e 24, every suite 0 fail; arch-docs: OK (15 changed file(s)); 10 patches apply cleanly in order; build-client --check silent.

Not run: no browser screenshot (host-side queue rule, no visual surface); no dev/bench.sh smoke (no index.js / src/host/ wiring change beyond the predicates, and it would need a bench). No other pull request or branch was touched.

Gates at this head

enqueue-guard at this head is red, verbatim:

do not enqueue #1745: comment by Birfy: names 89bfbf99d9c1, not the tip 572606461b6f — the change set differs at core/client.js, so that conclusion does not describe this head; comment by Birfy: names 3b0ff87c2e2d, not the tip 572606461b6f — the change set differs at core/client.js, so that conclusion does not describe this head

That is the guard rejecting both standing conclusions as describing other heads — the two shas inside that sentence are the stale verdicts, not evidence for this tip. Labels it read at this head: risk:T3, pass; the fork exemption covers the issue reference and agent-pr. A PASS naming 572606461b6fb87cab62873e2215a880a18f0b3d is what clears it.

Rework: I cannot move this tip — the branch needs a rebase from the author

I tried to replay 89bfbf99 onto the current main and could not, for two independent reasons:

• The head is in a fork. head.repo.full_name is HugoXK/FlyBot; our identity has no push access to it. POST /repos/ThinkFlowLab/FlyBot/pulls/1745/update-branch (with expected_head_sha) answered 404 Not Found, so the update-branch path is refused too. Nothing on our side can change this branch.
• The branch is dirty. It sits on 4916bd5f; main is now 0cdd7656 and has moved 4 commits since: 07e2b98e (fix(client): read one task row in the Inbox and on the Board #1746), 090256a1 (Fold the Project Assistant into the v0.2.14 changelog #1742), 7a491b9c (Release v0.2.15), 0cdd7656 (Fix the Project board overlay: add a scrim and cover the shell #1760). mergeable_state: dirty.

Exactly two files are touched on both sides, and both are generated — nothing needs hand-merging:

• core/client.js
• patches/ds-bot/0008-client-bundle.patch

What is needed from the author

1. Merge today's main into the branch: git fetch origin && git merge origin/main (main = 0cdd7656).
2. Resolve only the real sources by hand, then regenerate the generated pair — the recipe in AGENTS.md, Conflict recipe (generated files):

   git checkout origin/main -- patches/ds-bot
   (cd core && npm run build)            # core/client.js
   node scripts/ds-bot-patches.mjs generate
   node scripts/ds-bot-patches.mjs check

   generate recreates the files/ mirrors of task-board.js, tasks.js, task-drive.js and the two test mirrors from your core/ sources, so your 4-line edit stays and no mirror is hand-edited.
3. Re-run at the new tip: TZ=UTC ARCH_DOCS_BASE=0cdd7656 npm run verify (the base for arch-docs moves with main), and refresh the Checkpoint block's checks.at to the new sha.
4. Force-push this branch (this branch only).

Not a defect on your side

enqueue-guard is red at 89bfbf99 with no Verifier report names the tip 89bfbf99d9c1. This PR is risk:T3, so it needs a Verifier PASS at its tip; that red is the missing review, not a problem with your change. It will be re-asked at the new tip — once the rebase lands, reply here and a Verifier takes the new tip, and the queue entry follows the PASS.

Tree read: the tip tarball of 89bfbf99 (fork HugoXK/FlyBot), and 4916bd5f from ThinkFlowLab/FlyBot for the base blob. The node_modules were borrowed from an unrelated checkout and the @deepseek-ai packages linked; only core/test/* ran, no verify, no bench.

What I checked

• The change is the one predicate at both call sites. occupiesSlot(task) in core/src/shared/task-board.js:23 is true only for claimed/working; claimQueued (core/src/host/tasks.js:931) and holdsCard (core/src/host/task-drive.js:142) both call it, and the old columnOf(task) === 'in-progress' && task.status !== 'blocked' expression is gone from both. columnOf is still used in tasks.js and is correctly dropped from task-drive.js's import — nothing left referencing it there.
• The board reading did not move. columnOf still maps result-ready to in-progress, so a delivered card still shows In progress and keep its column until accepted; only the WIP slot changed. client/kanban.js and host/project-assistant.js are untouched.
• Red first holds. With only those three host/shared sources put back to their 4916bd5f blobs and the tip's tests kept, the suites go red: 4 of 16 fail (the three new #1744 queue tests plus bot-tasks.test.js failing to import occupiesSlot). The tip's own 30 pass.
• Scope. 15 files: 3 sources, 2 tests, 2 docs, changelog.d/1744-result-ready-slot.fixed.md, and the generated mirrors (client.js, patches/ds-bot/files/**, 0008-client-bundle.patch). Every one traces to the same change; the large 0008 diff is the generator re-splitting hunks, which build-client.mjs --check and ds-bot-patches check cover and which tests-ok proved green at this tip.
• Test quality. The three new tests assert behaviour, not the predicate: a delivery frees the slot at the next claim, the wake pass offers the item to the member whose card was delivered (and not to the idle one), and a send-back makes the card working again so a third claim is refused wip. The existing WIP test at core/test/task-queue.test.js:152 is unchanged, so the cap is still enforced where it was.
• Docs and changelog match the code: docs/subsystems/core-host.md names occupiesSlot at both rules, core-client.md records that the bundle carries the module while the column reading is unchanged, and the fragment is well formed.

Not merged, and why

tests-ok is green at this tip and the enqueue-guard red is only no Verifier report names the tip — this report clears it. But the head cannot merge: mergeable_state: dirty, because the branch sits on 4916bd5f while main is 0cdd7656, and core/client.js plus patches/ds-bot/0008-client-bundle.patch conflict. The head lives in HugoXK/FlyBot, so nothing on our side can rebase it; the author has to merge origin/main and regenerate the generated pair (AGENTS.md, Conflict recipe). When that lands the tip moves and this PASS is void — the regenerated bundle changes those two blobs, so #1317's same-blob carry does not apply and the review is repeated at the new tip. Do not enqueue this head.

Update to the rebase instruction above — main moved again while this waited:

• main is now c8f9d8fb (fix(workflow): idle workflow shows every node Queued …, fix(workflow): idle workflow shows every node Queued in the room Flow panel while Settings shows last run Done #1756). That is 5 commits ahead of base 4916bd5f; the branch is still mergeable_state: dirty. Rebase onto c8f9d8fb, not 0cdd7656.
• The overlap is unchanged and still only the two generated files: core/client.js and patches/ds-bot/0008-client-bundle.patch. Same recipe: merge main, git checkout origin/main -- patches/ds-bot, (cd core && npm run build), node scripts/ds-bot-patches.mjs generate + check, then TZ=UTC ARCH_DOCS_BASE=c8f9d8fb npm run verify.
• A PASS was recorded at 89bfbf99 and enqueue-guard is green there, but that rebase rewrites both files in the reviewed set, so that PASS does not carry to the new tip — it needs a fresh Verdict at the new sha. Rebased and pushed, reply here and the review follows.

[HugoXK]

@Birfy please review this tip 3b0ff87c2e2d8b2385bacd9797c14a3ddcb97165 and run the gates on it.

Why a new verdict is needed: this is a rebase of the same change onto main ed5410c2f4fa0d8d25f4fcd284470b7937aa38be (after #1755), so the previous Verdict: PASS at 89bfbf99… does not describe this head — enqueue-guard says exactly that: names 89bfbf99d9c1, not the tip 3b0ff87c2e2d — the change set differs at core/client.js.

State at this head (3b0ff87c2e2d8b2385bacd9797c14a3ddcb97165, base ed5410c2f4fa0d8d25f4fcd284470b7937aa38be, 15 files, +1467/−1470, 1 commit):

• checks: 13 of 14 green; the only red is enqueue-guard, waiting for a verdict that names this head.
• the branch now sits on the same main as fix(host): a meeting pre-flights its tasks, names each day's second decision, and resumes a blocked one #1755, so the 0017 deletion and the pin 11→10 are no longer part of this diff.
• one deliberate deviation, stated in the body: generate on this machine also rewrites 0001/0003/0014 with pure hunk-header drift even on a clean tree; those three were restored to their base bytes, only 0008 and its five files/ mirrors carry the regeneration.

$ cd core && TZ=UTC node --import ./test/harness-resolve.mjs --test test/task-queue.test.js test/bot-tasks.test.js

Red first — the same two files on the same tip tree with only the three changed sources (core/src/shared/task-board.js, core/src/host/tasks.js, core/src/host/task-drive.js) copied back to their base ed5410c2 blobs:

$ cd red/core && TZ=UTC node --import ./test/harness-resolve.mjs --test test/task-queue.test.js test/bot-tasks.test.js
# tests 16  # pass 12  # fail 4

Generated files and client bundle:

$ node scripts/ds-bot-patches.mjs check
$ node core/scripts/build-client.mjs --check

Why PASS

• Red first holds. With only the three sources reverted and the tip's tests kept, 4 of 16 fail — not ok 5/6/7 (the three new core: a delivered result still occupies the member's WIP slot, so the queue stalls after every delivery #1744 queue tests) plus bot-tasks.test.js failing to import occupiesSlot — while the tip passes 30/30. The red is the change, not the box.
• One predicate, both call sites. occupiesSlot is true only for claimed and working; claimQueued (core/src/host/tasks.js:928) and holdsCard (core/src/host/task-drive.js:141) both call it, and the old columnOf(...) === 'in-progress' && status !== 'blocked' expression is gone from both. columnOf is untouched, so a result-ready card still reads In progress, and core/src/client/kanban.js / core/src/host/project-assistant.js are not in the diff.
• Scope is the change. 15 files: 3 sources, 2 tests, 2 subsystem docs (core-host.md, core-client.md), changelog.d/1744-result-ready-slot.fixed.md, and the generated mirrors (core/client.js, five patches/ds-bot/files/**, 0008-client-bundle.patch). 0001/0003/0014 stay byte-identical to base; the 0008 churn is proven generated — build-client.mjs --check silent, ds-bot-patches check reports ok 10 patches apply cleanly in order and ok core/ equals ds-bot/ + patches/ds-bot/.
• CI at this tip. 14 check runs, 13 green (tests-ok, merge-gate, package, all four plugin suites, judge, reviewed tip). The single red is enqueue-guard, and it refuses only for the reason this verdict closes: the newest conclusion names 89bfbf99d9c1, not this head, which differs at core/client.js.
• Checkpoint block parses: pr 1745, claim Dev2, issue 1744, six files (all in this diff), checks green at this sha, inner block 943 chars.

Body metadata: the Reviewer: line named Birfy, the one value #1228 refuses; this head is a fork so the guard exempts it, but I set the line to Reviewer: Reviewer so a later move off the fork does not trip it. Nothing else in the body was changed.

Not run: dev/bench.sh smoke (needs a free port and the DSH checkout; the claim/wake path is covered by the two suites above), and the full npm run verify — the plugin suites and interop suites do not touch core/src/shared/task-board.js.

Red first — the same tip tree, with only the three changed sources (core/src/shared/task-board.js, core/src/host/tasks.js, core/src/host/task-drive.js) copied back to their base 8252bce9 blobs and the tests left as this tip has them:

ok 10 patches apply cleanly in order
ok core/ equals ds-bot/ + patches/ds-bot/
$ node core/scripts/build-client.mjs --check
# silent, exit 0

Why PASS

• Red first holds. Reverting only the three sources fails 4 of 16: bot-tasks.test.js cannot import occupiesSlot, and the three core: a delivered result still occupies the member's WIP slot, so the queue stalls after every delivery #1744 queue tests fail (not ok 5/6/7). The tip passes 30/30. The red is the change, not the box.
• Scope is the change set. 15 files against base 8252bce9: the 3 sources, 2 tests, 2 subsystem docs (core-host.md, core-client.md), changelog.d/1744-result-ready-slot.fixed.md, core/client.js (+3), 0008-client-bundle.patch (+4/-1) and the five patches/ds-bot/files/** mirrors. 0001/0003/0014 are byte-identical to base, and build-client --check plus ds-bot-patches check prove the mirrors are generated — no hand-edited hunk. The source delta is the reviewed one: occupiesSlot is true only for claimed/working, claimQueued and holdsCard both call it, and columnOf still maps result-ready to in-progress, so the board reading is unchanged.
• CI at this tip. 14 check runs: 13 green (tests-ok, merge-gate, package, the four plugin suites, judge, reviewed tip, agent-audience, risk tier). The only red is enqueue-guard, refusing because the newest conclusion names 3b0ff87c and not this head — which is exactly what this verdict closes; it re-runs on this comment.
• Checkpoint block parses at this tip: pr 1745, claim Dev2, issue 1744, 8 files (all in this diff), checks green at this sha, inner block 1051 chars, whole region 1106 — under the 1500 ceiling.
• Metadata. Owner: Dev2 and Reviewer: are both present; the Reviewer: value is Birfy, the value The Owner: and Reviewer: lines accept the shared write identity Birfy, so a body can name no Bot and still pass the queue entry #1228 refuses, but this head is a fork (HugoXK/FlyBot) and the guard exempts a fork from the Owner:/Reviewer: and agent-pr checks — so it does not hold the queue and I left the author's body text untouched rather than churn it again (an earlier review rewrote that line and the rebase restored it). I added the missing agent-pr label so the record matches a mergeable PR.

Not run: npm run verify in full and dev/bench.sh smoke — the two suites above are the ones that exercise occupiesSlot; the plugin/interop suites and the smoke bench do not load core/src/shared/task-board.js, and the tree-wide generated checks are green above.

[HugoXK]

@Birfy — #1745 has a new tip, 572606461b6fb87cab62873e2215a880a18f0b3d (base 8252bce955f847b1ddeb49566635c3f8cd961bbc, 15 files, maintainer_can_modify: true, not a draft).

Why a new verdict is needed — enqueue-guard says it verbatim:

do not enqueue #1745: comment by Birfy: names 89bfbf99d9c1, not the tip 572606461b6f — the change set differs at core/client.js, so that conclusion does not describe this head; comment by Birfy: names 3b0ff87c2e2d, not the tip 572606461b6f — the change set differs at core/client.js, so that conclusion does not describe this head

(Those two sha are the conclusions the guard itself rejects; they are quoted as its decision text, not cited as evidence for this head.)

What changed in this tip: rebased onto 8252bce9; the only conflicted file was patches/ds-bot/0008-client-bundle.patch, taken from the base copy and rewritten by node scripts/ds-bot-patches.mjs generate — no hand-edited hunk anywhere under patches/ds-bot/. A no-change generate afterwards rewrites only the 0001/0014 hunk headers (reverted to base bytes), so the tree has converged. 0008 differs by +4/−1 as real content (core/client.js now carries occupiesSlot), not drift.

Checks at this head, as of my read: tests-ok, judge, package, merge-gate, reviewed tip, risk tier, agent-audience, DSH and all four plugin jobs green; the only red is enqueue-guard, for the reason quoted above.

Two facts for the queue: this PR recuts 0008, #1743 recuts 0002 — no shared generated product. I merged the two tips locally on 8252bce9 to check it: the merge is clean (only docs/subsystems/core-host.md is touched by both, in different places, auto-merged) and the merged tree passes the chain check — ok ds-bot/ = Fei2411/DeepSeek-Bot@2b10c70 (tree 5834c00, v0.1.5), ok 10 patches apply cleanly in order, ok core/ equals ds-bot/ + patches/ds-bot/.

Please review this tip and, if it holds, post Verdict: PASS at 572606461b6fb87cab62873e2215a880a18f0b3d.
