Handover for the next domain:ui execution-seat PM — what will burn you, what I got wrong, and what is waiting #7233
Description
Written at the end of a domain:ui dispatch shift (session session_012wwHa4aaFybxXrfmfHioDM, 2026-09-01). Successor to objectui#7089, whose §6 is still the most useful paragraph written about this seat.
documentation + domain:ui + pm:queue + priority:p1 on purpose, and linked from the seat post #5560. objectui#7089 carried domain:ui and nothing else — no pm:*, no priority:* — so no query a successor runs returned it. I found it by accident, five hours into my shift, in a sweep I was running for an unrelated reason, and by then I had independently re-derived its central lesson four times. That was the single most expensive thing that happened today. If you write a handover, label it.
Ordered by what will cost you, not by topic.
1. ⭐ The one thing to carry forward: put YOUR OWN readings in the premise-verification gate
objectui#7089 §6 says it, and I proved it six more times. Six PM premises of mine were falsified by the lanes I dispatched, every one caught because the dispatch order told the dev to verify the PM's claims, not just the card's:
| my premise | what it was |
|---|---|
the grid builds $select at one site |
two, and each fails alone — a one-site fix ships with a green suite and a broken surface |
description was the only read-but-unrelayed key |
three of 46 relayed keys; fieldOrder and rowColor too |
| the grid's paging footer discloses page-scoping | it belongs to plugin-list; a standalone grouped grid renders no footer at all |
| a gantt issues two requests per load | three — one paged, two unbounded |
| ZONE 1 RULING: raise the Start/End threshold, the dates survive as a sublabel | the sublabel is display:none above 640px — the "fix" would have deleted the dates |
ZONE 1 RULING: gate the column list feeding buildExpandFields |
gating the input widens the leak, because the helper reads an empty list as "no restriction"; the gate belongs on the output |
Two of those were rulings, not mechanism notes. Both were withdrawn on measurement. Write your orders so a lane can overturn you, and say explicitly that a clean stop on a falsified premise is a full success — one lane returned with no PR and no code, and it was the most valuable result of its round.
And the worst one: I filed objectui#7225 asking for work a standing maintainer ruling on #6482 already forbids. I had read #6482's body and not its comments. My stated reason for filing new rather than reopening ("a five-week-old snapshot") was also false — it was six days old. ⇒ Read the comments. Every time. #7089 §1 says the same thing and I still did not do it.
2. Probe discipline — I produced FOUR false zeros in one shift
A probe can fail in two directions and I hit both:
Cannot match anything (reads as "clean"):
- wrong path, twice —
ObjectStackAdapter.tsdoes not exist (the class lives inindex.ts); a script run from outside the repo - in ERE,
(a|b)consumes group 1, so a\1backreference meant for a later group silently matches nothing and exits 0
Matches BOTH sides (reads as "landed" — the harmful direction):
- I probed
scrollPos/xToDateto check whether PR fix(plugin-gantt): derive the toolbar period label from the visible window, and wire the period steppers #7227 had landed. Both already existed on main — that is precisely why the lane could reuse them. It would have reported a landing that had not happened, and I would have posted a landing note and closed the card against absent code.
⇒ Before trusting any landing probe, verify it is 0 on main AND non-zero on the branch. Derive it from the diff; never guess a symbol name. Two names I guessed (periodStartFor, labelPeriodFor) return 0 on both sides — they do not exist, and either would have been a permanent false negative.
Also standing: git grep -c counts LINES, not entries — use grep -o … | wc -l. And probe for the REPLACEMENT's presence, not the removed token's absence: house style states what was wrong before stating what is right, so a removed phrase is systematically still present in the very file that removed it. When the file's own prose quotes the old form, count whole lines.
3. Environment traps, all measured today
- ⭐ happy-dom / jsdom report
clientWidth0 and therefore NEVER fire container-size effects. A gantt's auto-scroll-to-Today is its whole first-paint reproduction and is unmeasurable in the DOM harness — not unreliable, unmeasurable. They also apply CSS@mediarules regardless ofinnerWidth, sogetComputedStylereturns the same value at 500 and 1440. One lane would have concluded "this element is never visible" from that. Use the preinstalled Chromium at/opt/pw-browsers; ⛔ never runplaywright install. enable_pr_auto_mergeechoesmethod: MERGEeven when SQUASH is requested and correctly applied. Seven times today. Ignore the echo; verify by parent count after landing (1 parent = squash).- The angle-bracket sanitizer eats issue and PR BODIES — a
<followed by a letter is stripped, and if unclosed it takes everything to the end of the body. Backticks do NOT protect it. Comments are safe. Six bodies lost evidence to it today, including two cards' own JSX snippets. Read your posted body back as rendered. - The closing-keyword parser ignores negation. There is no safe way to write "does not close #N" — omit the number.
- API rate limit hit three times, recovering in a few minutes each. Git reads cost zero quota — queue state,
main, PR diffs and file contents are all readable. ⛔/rate_limitreporting quota remaining is not evidence the channel is open; a lane proved that while its search was still refusing. - Merge queue: confirm enqueue by
git ls-remote origin 'refs/heads/gh-readonly-queue/main/pr-NNNN-*'— positives only, ref-absent proves nothing. Judge landing bygit merge-base --is-ancestor QUEUE_BUILD_SHA origin/main, never a branch head. - ⭐ Pre-check conflicts against what
mainis ABOUT to become, not only what it is. I caught fix(app-shell,plugin-list): relay and resolve a list view's own description #7220 conflicting with fix(grid,list,core): union a grid's grouping fields into the query projection #7214's queue build before the queue did, and disarmed it — an ejection rebuilds every entry and taxes whoever else is waiting.mainmoved seven times in three hours today.
4. Landed this shift
| PR | card | note |
|---|---|---|
| #7213 | #6943 | a red gate on main (check:published-dist), found in the unlabelled sweep |
| #7214 | #7179 | grid $select blind to grouping.fields[] — both sites |
| #7223 | #7210 | gantt paging footer — halves 1 and 3 only |
| #7220 | #7199 | per-view description relay + i18n locale map |
| #7226 | #7189 | grouped-grid partial disclosure — disclosure half only |
| #7227 | #7203 | gantt toolbar period label + steppers |
| #7229 | #7215 | $expand FLS gate — in the queue as this was written |
$select projection gated its columns and then re-added the expand roots unconditionally, justified in-comment as "known-valid because buildExpandFields() derived them from the object schema" — valid, yes; readable, never asked. A denied lookup walked straight back in. If you audit FLS, do not trust #6898 as settled history.
5. Open on purpose — do NOT close these as done
- A gantt lens fetches its rows twice — once paged (which feeds the footer) and once unbounded (which feeds the chart), so the footer misdescribes the chart and the real fetch has no ceiling #7210 half 2 — may a non-grid view fetch unbounded? Halves 1 and 3 shipped; this is untouched.
- Grid grouping and its per-group counts are computed over the fetched page, so a group can be missing entirely with nothing on screen saying so #7189 — server-side grouping. ⭐ The disclosure that landed is honest and tells users about records they cannot reach:
useServerPagination = !hasInlineData && !isGrouped(ObjectGrid.tsx:3224), so a grouped grid owning its fetch has no server pager at all. Records past the first window are unreachable, not merely undisclosed. Disclosure is a ceiling here, not a floor. - plugin-gantt: the task list is capped at 320px and its Start/End columns take 160px of that, so task names get 53px and truncate to ~7 characters while 864px of chart sits empty #7204 + plugin-gantt: between 640px and 1023px the task-list rows carry NO dates at all — the Start/End columns are gated off and the date sublabel is display:none from 640px up #7224 + finding(plugin-gantt):
columnWidthForContainerbranches on container width and returns 110 from all three arms — the breakpoints it documents do nothing #7228 — three gantt container-width helpers, one decision. plugin-gantt: between 640px and 1023px the task-list rows carry NO dates at all — the Start/End columns are gated off and the date sublabel is display:none from 640px up #7224 is live onmain: between 640px and 1023px a task row shows no dates at all, because one gate reads a container width and the other a viewport media query and neither is the other's complement. - The grid's inline cell editor scopes a
dependsOnlookup by the SAVED row, not the staged one — carry the pending record across therenderCellEditorseam (option B of #7165) #7188 + finding(types): 18 schemas narrow inheriteddisabledtobooleanwhile 0 narrow its twinvisible— no ruling says which is intended #7087 — ⛔ both maintainer-ruled AND build-ready, blocked only by the exhaustedCONTRACT_REVIEW_TIER. The analysis is finished on both; only the review gate is missing. This is the seat's binding constraint. - finding(cli/vscode/core): the
bodydialect has PRODUCERS and generic readers outside objectui#6771's population —objectui initscaffolds every new project in it #7181 — an ordering constraint on finding(sdui-parser/components): the manifest tier reportsunknown-proponbody— the one child-list key 10+ registrations actually honour #6771's already-ruled retirement:objectui initemits 53bodynodes, so step 4 cannot land before producers move, or every freshly scaffolded project fails its own firstvalidate. useSettledSchemawas extracted and published with ONE adopter — the convergence #6482 asked for is 1 of 4, and the gantt's ungated double fetch is still live #7225 — answered-by-ruling; the A/B/C amendment question is on [PM seat] domain:ui @ objectui — 🟢 sunhaolin · session_0188TsgPV8kQXfuRuKmkj2ks · batch 3 · dev #12490 #5560.
6. Queued and ready, rulings already recorded in their triage comments
#7173 · #7096 · #7216 · #7218 · #7217 · #7230 · #7231 · #7232
Each has a triage comment with the disposition already argued, so dispatch is short.
7. The unlabelled pool — measure it, do not estimate it
55 of 307 open issues carry no labels, measured repo-wide with a count cross-check (100 + 100 + 100 + 7 = 307, final page hasNextPage: false) and controls in both directions. All 55 are numbered ≥ #6790 — pages 3 and 4, 107 issues over five weeks, are 100% triaged.
⇒ This is filing outrunning triage right now, not chronic debt. Do not plan a burn-down; the failure is that a card can be filed into a state no sweep returns.
I worked ~19. ~36 remain unread. ⛔ Never grade from titles — that shortcut is what #6318 cost a lane.
That pool has already yielded: a red gate on main (#6943), this seat's own handover (#7089), an ordering constraint on a ruled retirement (#7181), and a second build-ready tier-blocked card (#7188). It is the highest-yield thing to do with spare capacity.
8. Two rulings of mine you may want to overturn
① Split a card when one half is invariant to the open question. #7210's footer fix shipped while its unbounded-fetch decision stayed open, because "whichever way it is settled, the footer and the chart should describe the same fetch." Same for #7189. This got work moving without pre-empting a maintainer — but it does leave cards open with a landed PR attached, which reads oddly in a sweep. Make sure the landing note says loudly what is still open.
② File a narrow card rather than reopening a stale one. I did this for #6482 → #7225 and it was wrong (§1). The reopen-vs-file test I would use now: reopen when the original card's asks are undischarged; file new when the tree has moved past its description. I applied the second test without checking whether the first applied.
9. Seat mechanics worth keeping
- A claim is assign PLUS a claim comment carrying session ID and branch — all agents share one GitHub identity, so the assignee field alone proves nothing. Re-read comments before writing code.
- Dispatch orders in three zones: ZONE 1 ruling (not re-adjudicable) · ZONE 2 the PM's own assumptions, falsify freely · ZONE 3 suggested route. The zone-2 block is where every one of §1's six corrections came from.
- File-overlap is a real scheduling constraint. Three queued cards were held today not on priority but because they touch a file a running lane was editing.
- Landing verification is by CONTENT with a live control, never by sha (squash makes a new commit). The control is what catches a probe that would pass against a deleted feature.
Good luck. The lanes on this repo are very good — four of them corrected me today, and every correction improved the result. Write your orders so they can.

Completion note — §4's table is now final

67dadd602—$expandFLS-gated at both projection sites. Verified by content with three live controls (#7214, #7223, #7220 markers all still present inListView.tsx, which four PRs touched in sequence today), and squash confirmed by parent count.Final tally: 7 landed
39d69ad53a6d8b8d445015fcf52f626808d48952395b4231d1b93c67dadd602Plus #7225, which correctly produced no PR — a standing maintainer ruling on #6482 forbade its shape, and the lane found it because the dispatch order told it to verify the PM's premises. That is §1's sixth entry and the one I would most want a successor to read.
One addition to §1, from #7229
The count in §1 stands at six, but the second withdrawn ZONE 1 ruling deserves its detail recorded here rather than only in the table: I ruled the
$expandgate onto the input column list. Gating the input would have widened the leak —buildExpandFieldsreads an empty column list as "no column restriction" and falls back to every declared relation — and the no-columns case has no input to gate at all, which is the default shape of three surfaces. Both failure modes are pinned as tests in PR #7229.One addition to §4, worth its own line
objectui#6898 was believed closed and had a live bypass. The
$selectprojection gated its columns and then re-added the expand roots unconditionally, justified as "known-valid… derived them from the object schema" — valid, but readability never asked. Measured pre-fix, a denied lookup was present in$select. Anyone auditing field-level security should treat #6898 as reopened-and-reclosed by #7229, not as settled history.The same ungated pattern survives at five more build sites (#7230) — calendar, gantt and record-detail pass no column list at all.

Addendum — the binding constraint lifted, seat resumed, and one correction to §5
domain:uiseat, sessionsession_012wwHa4aaFybxXrfmfHioDM, 2026-09-02T00:47Z.The constraint this handover was written under is gone
The maintainer restored Fable 5.1 (「Fable 5.1 恢复了 现在可以继续了」).
CONTRACT_REVIEW_TIERis open, and this seat is now running as the tier. The two cards §5 named as "maintainer-ruled AND build-ready, blocked only by the exhausted tier" were dispatched within the hour, both atmodel: fable, bothClause-②: yes, with the tier verdict quoted fromdispatch-gates.mjs --tierin each claim comment rather than recalled:disabledtobooleanwhile 0 narrow its twinvisible— no ruling says which is intended #7087 →claude/issue-7087-disabled-narrowingdependsOnlookup by the SAVED row, not the staged one — carry the pending record across therenderCellEditorseam (option B of #7165) #7188 →claude/issue-7188-pending-row-ctxPost-delivery Clause-② review is in-seat at tier (maintainer 2026-08-31 ruling): PASS ⇒ strip
needs:contract-review, ready, auto-merge; FAIL ⇒ patch round; ⛔ never release unreviewed; a real design fork still goes to the decision box.§5 says of #7188 and #7087: "both maintainer-ruled AND build-ready." Half right. #7087 carries a maintainer ruling (2026-09-01, 「同意」, option 1 scoped to
disabled). #7188 does not — its A/B split was this seat's ruling on #7165, and the card's own body defers the shape to the maintainer. I repeated the overstatement in the triage comment, the seat-post title, and here, and only caught it on re-reading the comments before dispatch. It is corrected on the card (comment 5502616875) and the shape is now ruled at tier there, with the reasoning for why it is not a design fork.The lesson is the one §1 already carries, applied to my own summary rather than a card: a claim I wrote yesterday is a reading, not a measurement, and it has to be re-verified before being acted on — even when I am the one who wrote it.
What the lift does NOT do
The #5560 standing list has other items that were also tier-blocked — #7206 option B, #6771 steps 2–5, #7181, #7212, #7194, #7182, #7071, #7183. ⛔ Most of those still need a maintainer ruling that has not arrived. The tier being open removes one blocker, not the other. Each must be re-read (body AND comments) before any is dispatched; none is to be dispatched from this list by memory.
For the record
The seat was idle roughly eight hours between the wind-down at ~16:20Z and the resume at 00:47Z. Nothing this seat owns moved in that window: all seven landings from the previous shift remain ancestors of

The raising seat's evidence that both documents are still live was specific and was accepted without re-derivation: it took working facts out of them this round (the premise-verification discipline that falsified two of its own premises on #8885 before dispatch, the docs-changeset shape carried into #8912, the
plaintext-fence blind spot that re-pointed #8912's acceptance tool at rendered output).Why the labels were there, and why removing them costs nothing now
⛔ This is not a finding that the previous seat was careless — the opposite. #7089 carried
domain:uiand nothing else, so no query a successor ran returned it, and it was found by accident five hours into a shift after its central lesson had been independently re-derived four times. That cost was real, it is documented on the cards, and labelling them was a deliberate repair of it.What has changed is that the repair now has a correct carrier. The raising seat restored the named handover pointer to seat post #5560's body as a titled section, so it is inherited by each rewrite instead of being dropped by one — which is exactly how the original pointer was lost. Findability no longer has to ride on a dispatch-queue label, so the conflict dissolves rather than being traded off.
Every successor
domain:uiseat that ran the card-selection total order hit these two at the top of its queue and had to read both in full to discover they were not work. That happened again this round, as entries 1 and 2. Two seats have now paid it.This is an instance, not the class
Both cards are instances of open lane card objectui#8680 — "
pm:queueis carrying two incompatible meanings — 'triaged' and 'ready for a dev'". Five of this fire's tenpm:retriagecards share that shape. #8680 is graded this round as the class card; these two are disposed of on their own facts and do not wait on it.Generated by Claude Code
