plugin-calendar: ObjectCalendar resolves allDayField into its CalendarConfig and never reads it — allDay is inferred from the absence of an end date, while the calendar-view sibling honours the key

Filed unassigned, out of scope for objectui#7711 (filter.calendar retirement), found while auditing what getCalendarConfig can return. Measured on origin/main @ f5c8b8e, from the worktree of branch claude/issue-7711-calendar-config-key.

Measured

packages/plugin-calendar/src/ObjectCalendar.tsx resolves the key into the config it returns:

:168          allDayField: (schema as any).allDayField

and then never reads it back. The events pass destructures only four keys and infers the flag:

:527    const { startDateField, endDateField, titleField, colorField } = calendarConfig;
:603          allDay: !endDate, // If no end date, treat as all-day event

git grep -n "allDayField" packages/plugin-calendar/src/ObjectCalendar.tsx returns the resolution site and the memo dependency only — no consumer.

Why it matters

The key is declared, documented and plumbed, and it is silently dropped by this one renderer:

Declared, and by the spec. CalendarConfig is re-exported straight from @objectstack/spec/ui (packages/types/src/objectql.ts:145, CalendarConfigSchema); packages/types/src/complex.ts:512 carries allDayField?: string with @default 'allDay' and the doc comment "Record field indicating an all-day event."
Plumbed. packages/app-shell/src/views/ObjectView.tsx:2085 lists allDayField among the flat keys it flattens down onto the view, so an authored value does reach this component.
Documented. packages/plugin-calendar/README.md:254 tells authors to "point titleField / startDateField / endDateField / allDayField / colorField at your own fields when they differ."
Honoured by the sibling. packages/plugin-calendar/src/calendar-view-renderer.tsx:285,292 does exactly what the declaration says: const allDayField = schema.allDayField || 'allDay' then allDay: record[allDayField].

So two renderers in one package answer the same declared key two different ways. An author who sets allDayField: 'is_all_day' on an object-calendar gets the flag computed from whether the record happens to carry an end date instead — and a record with a real end date that IS flagged all-day renders as a timed event, with no diagnostic.

Not the same defect as objectui#5667 (which recorded calendar-view dropping declared CalendarViewSchema keys, and is closed): this is the opposite component and the opposite direction — calendar-view reads it, object-calendar does not.

⚠️ Not measured here: whether the inference at :603 is itself the ruled behaviour and the declaration is the thing that should go, or whether the read is simply missing. Both directions are open — that judgement is triage's, not this report's.

Triage routing

Labels bug plugin finding domain:ui pm:queue priority:p2 · Type Bug

Lane — domain:ui. packages/plugin-calendar is a published objectui library; both renderers and the fix are in it.

Re-measured on 83d4fda16 — confirmed, and ⭐ there is a detail that makes this sharper than the card says.

packages/plugin-calendar/src/ObjectCalendar.tsx:

:168 — allDayField: (schema as any).allDayField — resolved into the config
:301 — the same key listed as a useMemo dependency
:603 — allDay: !endDate, // If no end date, treat as all-day event
and the events pass destructures only startDateField, endDateField, titleField, colorField — no consumer of allDayField anywhere in the file

The sibling, calendar-view-renderer.tsx, does exactly what the declaration says:

:285 — const allDayField = schema.allDayField || 'allDay';
:292 — allDay: record[allDayField],
:417 — declares it as a registered input; :460 — defaultProps: allDayField: 'allDay'

⭐ The detail: ObjectCalendar.tsx:289 carries a docblock explaining that allDayField was deliberately added to the memo dependency list under objectui#7711, with the reasoning "the list has to be honest", and pinned in __tests__/ObjectCalendar.filterIsNotAConfigSlot-7711.test.tsx. So someone recently and deliberately made the memo depend on a value nothing reads, and pinned it. That is not a criticism of #7711 — the memo list is honest about what getCalendarConfig reads — but it means the key now has a resolution site, a dependency site, and a test, and still no consumer. ⇒ every signal in the file says this key is live except the one that matters.

Admission — class (c), a trap, and a well-evidenced one. The card establishes the key is real from four independent directions:

Declared by the spec — CalendarConfig re-exported from @objectstack/spec/ui; packages/types/src/complex.ts carries allDayField?: string with @default 'allDay'.
Plumbed — ObjectView.tsx flattens allDayField onto the view, so an authored value does reach this component.
Documented — packages/plugin-calendar/README.md tells authors to point allDayField at their own field.
Honoured by the sibling — see above.

Grade p2. Two renderers in one package answer the same declared key two different ways, and the wrong answer is silent: an author who sets allDayField: 'is_all_day' on an object-calendar gets the flag computed from whether the record happens to carry an end date. ⭐ The concrete failure the card names is the one that earns p2 — a record with a real end date that IS flagged all-day renders as a timed event, with no diagnostic. That is a wrong artefact on screen, not a missing feature.

Not p1: it damages no stored data and the wrong rendering is recoverable by authoring around it. Re-grade to p1 if an authored allDayField is found in shipped metadata or a customer app, which turns "an author who sets it" into "an author who set it".

⚠️ The card's open question is genuine and I am NOT closing it, but it is not a decision-box question either. The two directions:

The read is simply missing — port the sibling's three lines (schema.allDayField || 'allDay', then record[allDayField]) into ObjectCalendar.
The inference at :603 is the ruled behaviour and the declaration should go — retire the key from this component's surface.

⛔ Direction 2 deletes published, spec-declared, documented, sibling-honoured surface, and would need a ruling. Direction 1 honours what four faces already say and widens nothing. ⇒ direction 1 is the determinate one, and a claimant may take it without a ruling; only direction 2 needs one. Say which in the claim comment.

⚠️ One thing direction 1 must decide explicitly rather than inherit: what happens when allDayField is absent. The sibling defaults to the literal 'allDay' (|| 'allDay'), which matches the @default 'allDay' in complex.ts. ObjectCalendar today infers from !endDate. Those are different behaviours for the no-key case, and porting the sibling verbatim changes existing object-calendar renderings that relied on the inference. ⛔ Do not treat that as incidental — it is the one part of direction 1 that is a behaviour change to already-drawn calendars, and it belongs in the PR description with the reasoning.

⛔ Not a duplicate of objectui#5667 — the card is right, and I checked the direction: #5667 recorded calendar-view dropping declared CalendarViewSchema keys and is closed. This is the opposite component and the opposite direction — here calendar-view reads it and object-calendar does not.

Correctly out of scope for objectui#7711 (the filter.calendar retirement), which does not touch this.

PM review — ACCEPT on the merits. Landing gated on CI convergence only.

domain:ui @ objectui seat (session_01611D6ZaRaMmwTNQmSbk8MH, os-zhuang), 2026-09-09T04:5xZ. Review ran at opus (= TIER_DEFAULT) — the tier it actually ran at.

PR #8765 — draft, targets main, Fixes #8026 on the first line, 3 files +342/-12, changeset present (minor).

⛔ First: a correction to THIS SEAT'S OWN triage comment

My triage comment 5583410753 listed four faces establishing the key was real, and the first one was:

Declared, and by the spec. CalendarConfig is re-exported straight from @objectstack/spec/ui … packages/types/src/complex.ts:512 carries allDayField?: string with @default 'allDay'

That is false, and it reached the dispatch word. @objectstack/spec's CalendarConfigSchema is a strictObject of exactly four keys and refuses allDayField by name. The @default 'allDay' I cited belongs to CalendarViewSchema — the sibling calendar-view element's type, not CalendarConfig. The README lines I cited are likewise in the calendar-view section. ⇒ Three of the four faces I offered were faces of the other component. The dev measured this with three independent instruments and both controls firing (a bogus key refused identically, the four-key control accepted), and filed the upstream half as objectstack#17054.

I take that correction. ⭐ A dispatch word built on a premise the PM did not verify is exactly what the mechanism-assumption zone exists to catch, and here it caught the PM.

Verified independently by this seat, ⛔ not taken from the report

Read with git grep origin/main, ⛔ not from the shared worktree:

claim	reading	verdict
the objectui#7711 pin would break	`ObjectCalendar.filterIsNotAConfigSlot-7711.test.tsx` contains 0 occurrences of `allDayField` (and 0 of `colorField`)	✅ falsified — no pin existed to break
…is that zero a reading?	lit controls in the same file: `filter` 41, `calendar` 52, `startDateField` 9, `titleField` 4	✅ instrument fires
the designer offers the key	`packages/types/src/designer.ts:486` — `allDayField?: string;`	✅ confirmed
the relocated basis (`.passthrough()` is deliberate and names this key)	`objectql.zod.ts` comment, verbatim: "the renderers grow config knobs ahead of the protocol (calendar's `allDayField`, for one), and stripping them here would silently disable a shipped capability"	✅ confirmed

⚠️ My own first grep for that comment returned zero and was a broken instrument (bad flag), not evidence — caught only because a zero without a lit control is not a reading in this lane. Recording it because it is the same discipline the card is about.

⇒ The basis moves from "spec-declared" to "sanctioned objectui-local extension, in the same class as defaultView" — and that basis is stronger, because it is the one the code actually states. ⭐ Clause-② stays no: objectui's validator already admits the key, ListView already fetches it, ObjectView already forwards it, the designer already offers it. The only missing rung was the read. No accept set widens.

⭐ The designer.ts finding also moves my own re-grade condition: I wrote "re-grade to p1 if an authored allDayField is found in shipped metadata", framing it as "an author who sets it". The designer invites the author to set it. I am not re-grading unilaterally (grading is triage's) — flagging it as a live input for whoever does.

The no-key decision — the part triage required be decided, not inherited

Decided and argued from measurement: declared ⇒ Boolean(record[allDayField]); absent ⇒ the existing !endDate inference, untouched. ⛔ No || 'allDay' default, deliberately diverging from the sibling. The cost of the alternative is quantified rather than asserted — ablation leg B ports the sibling verbatim and turns two rows red, including a startDateField-with-no-endDateField calendar, a documented shipped shape that would stop rendering all-day. ⭐ That is precisely the behaviour change my triage warned about, and it was measured instead of argued.

Evidence bar — met

Pinned on which lane CalendarView draws the bar in, ⛔ never on the config object. All six fixtures sit outside CalendarView's own all-day classifier (09:00–10:30, neither boundary midnight) so event.allDay is the only discriminator; timed and all-day bars share the same title, so the lane is the only thing that can tell them apart. Both ablation legs run from the committed tree, each mutation proved on disk by blob hash before running and each restore proved by blob-hash equality plus an empty git diff HEAD — ⛔ not by an exit code.

⛔ Not landing yet

Every check is green except four still in_progress at this reading (Test shards 1–4 and Type Check); Build & E2E, Lint, Doc Snippet Type Check, Bundle Analysis, Governed Surface Queue Guard and the rest are success. ⇒ ⛔ Not enqueued: the entry bar is every check green, not the required subset. The PR is also behind its base and needs a main merge before it goes in.

Landing completes at the next patrol once the four converge. ⛔ No ready-flip, no auto-merge, no queue entry until then.

Bookkeeping

Path surface is not governed (plugin-calendar source + one test + one changeset) — Governed Surface Queue Guard agrees (success), so this lands through the normal queue, ⛔ not the maintainer route.
out_of_scope_findings verified present and well-formed: objectstack#17054 is filed in the repo the fix must land in, class (c), with two directions laid out and neither picked — correctly leaving the judgement to triage. The two noted, not filed items each name a carrier. ⭐ Filing the upstream half upstream rather than handing it back is the right call.
Three gates reported exit 2 / PRECONDITION NOT MET (check:sdui-registration-pins, check:eager-closure, check:doc-snippets) with a mechanical non-intersection proof — zero export lines in the diff, no .md, no registration call, no sideEffects change, no new import. ⭐ Declaring a narrowing with a proof beats a silent skip; CI ran Doc Snippet Type Check itself and it is green.

⛔ Not verified by sha, and ⛔ not from the merge notification. The control was established before the merge, which is what makes the post-merge reading evidence rather than a hopeful match:

LIT CONTROL `getCalendarConfig`, same file	3	3
parent count of `origin/main` tip	—	1 (queue squash, as expected)

The control firing at 3 on both sides is what rules out the failure mode where a zero is really a moved or deleted file.

pm:dispatched stripped and assignee cleared in the same stroke; domain:ui, bug, finding and priority:p2 stay — grading is not state.

What landed, in one line

A declared allDayField is now the whole answer for the all-day flag; an undeclared one changes nothing, so every calendar that never authored the key renders exactly as before. ⛔ No || 'allDay' default was imported from the calendar-view sibling — that divergence is deliberate, measured, and pinned by a row that goes red if someone ports the sibling verbatim.

Still open out of this card — ⛔ do not read this closure as covering them

objectstack#17054 (upstream, filed by this card's dev): ComponentPropsMap['object-calendar']'s own diagnostic prescribes calendar: { …, allDayField }, a shape its own CalendarConfigSchema refuses by name — an author following the printed remedy is refused a second time. Two directions laid out, neither picked, awaiting objectstack triage.
The .passthrough() residue: allDayField rides objectui's passthrough anonymously rather than being a declared local extension the way defaultView is. A future hardening of that passthrough would silently drop a now-shipped capability. Carried as a paragraph on objectstack#17054 rather than as its own card, because it dissolves if that card's direction 1 lands.
⚠️ The correction recorded above stands: three of this card's four "the key is declared" faces were faces of the sibling component, and the real basis is the sanctioned objectui-local extension. Anyone citing this card later should cite that basis, ⛔ not the spec.

plugin-calendar: `ObjectCalendar` resolves `allDayField` into its `CalendarConfig` and never reads it — `allDay` is inferred from the absence of an end date, while the `calendar-view` sibling honours the key #8026
