ObjectCalendar's standalone object fetch never injects $expand — same empty-ref read objectui#6419 removed from ObjectView #6453
Description
Surfaced while implementing objectui#6419 (ObjectView's non-grid fetch never injecting $expand). Filed separately: different package, and this one affects the standalone calendar rather than the six views ObjectView hosts.
The defect
ObjectCalendar carries the identical shape objectui#6419 removed from ObjectView — a render-body ref write, read by a fetch effect that omits the schema from its dependency list:
packages/plugin-calendar/src/ObjectCalendar.tsx:242 objectSchemaRef.current = objectSchema;
:283 const expand = buildExpandFields(objectSchemaRef.current?.fields);
The effect's dependency list is
}, [hasExternalData, dataConfig, dataSource, hasInlineData, schema.filter, schema.sort, refreshKey]);
— objectSchema is not in it, and it is resolved by a separate effect. So on the one run this effect makes, objectSchemaRef.current is still null, buildExpandFields returns [], and the object provider's query goes out with no $expand; nothing re-runs the effect when the schema lands.
Scope — narrower than it looks
A calendar hosted by ObjectView or ListView receives its rows as data from the parent and never reaches this path, so objectui#6419's fix already covers that composition. What is left is the standalone object-calendar with dataConfig.provider === 'object': its lookup / master_detail / user / tree fields render from raw foreign-key ids.
Evidence class
Read from source, not measured — the instrumented run behind objectui#6419 exercised ObjectView, not this component. Whoever picks this up should measure it here before adopting a shape, exactly as objectui#6419 was required to: this effect's dependency set is again different (dataConfig, hasInlineData, schema.filter, schema.sort), so neither the kanban's numbers (objectui#6271) nor ObjectView's transfer.
Prior art for the fix
objectui#6271 (ObjectKanban) and objectui#6419 (ObjectView) both replaced the ref with a settled-and-keyed resolution — { key, def } | null — that GATES the record query. The part worth carrying over is that the gate is on the read having settled, not on a truthy schema: an adapter exposing no getObjectSchema, or a read that threw, must still fetch, or the view is empty forever.

MEASURED FIRST, on this component's own dependency set, before any fix: an instrumented adapter over three latency profiles showed origin/main issues 1 find with $expand NEVER present in any profile, so a standalone object-calendar paints raw foreign-key ids and keeps them. The alternative (objectSchema in the deps) issues 2 finds and — when the schema read is the slower of the two — paints raw ids, reverts to the 'Loading calendar...' placeholder, then swaps: a THREE-step paint, which is where this component parts company with #6419's two-step, because `loading` is an early return that replaces the whole grid and the re-run calls setLoading(true). When the schema read is faster, the first response is instead discarded on arrival — the kanban's regime. So this component spans BOTH prior verdicts depending on relative latency, and gating is the only shape correct in all three profiles. Replaced the ref with one settled-and-keyed resolution ({key, def} | null) that gates the record query; gated it is 1 find carrying $expand the first time in every profile, one paint, at 107/88/78ms vs 108/94/79ms via the deps. JUDGEMENT CALL, DECLARED: wrote the THIRD HAND COPY, not an extraction. Read what the two existing copies actually share first — the resolution half is genuinely common, but the gate half is not: this component keys on dataConfig.object ?? schema.objectName rather than schema.objectName, and gates one provider branch rather than the whole effect, because an inline `value` set issues no metadata read and a whole-effect gate would hold its query open on a resolution nothing was going to produce. A helper would also have to be a NEW EXPORT on the published @object-ui/react (AGENTS.md bars React from @object-ui/core) — a permanent public-surface widening — while refactoring two already-landed fixes inside a bug PR. Filed #6482 to ask the convergence question deliberately, with the divergence evidence. CLAUSE-2 CHECK, EXPLICITLY: NO PUBLIC SURFACE CHANGE. No **/src/index.ts is in the diff (0 matches) and no export line is added or removed (git diff -U0 | grep '^[+-].*\\bexport\\b' is empty); ObjectCalendar's props are untouched and the change is entirely component-internal state.", "tests": "All gate results quoted from each tool's own verdict line; exit codes captured before any pipe (redirect-then-capture), never through `tail`. Union run on the FINAL commit 6b1f48ba0. Every heavy command went through `bash scripts/pm/os-verify-lock.sh -c '...'` (objectstack copy; objectui has no scripts/pm/) — waits of 4m53s / 2m31s / 2m41s / 2m49s / 2m08s / 7m08s / 8m02s were spent doing lock-free work, never by ending a turn.\n\n(1) DEPENDENCY CLOSURE BUILT FIRST, before any judgement, so a stale dist/ could not lie in either direction: `pnpm --workspace-concurrency=2 --filter '@object-ui/plugin-calendar^...' build` -> BUILD_EXIT=0.\n(2) `pnpm exec vitest run packages/plugin-calendar/` (repo-root invocation with a path filter, per AGENTS.md — NOT `pnpm --filter <pkg> test`, which is the silent-green trap objectui#3378) -> `Test Files 14 passed (14)` / `Tests 101 passed (101)`, TEST_EXIT=0.\n(3) `pnpm --filter '@object-ui/plugin-calendar' run type-check` (hyphenated script name in this repo) -> TYPECHECK_EXIT=0, and the run echoed `> @object-ui/plugin-calendar@17.6.0 type-check` / `> tsc --noEmit && tsc -p tsconfig.test.json`, so this was not a zero-match filter passing as green. NOT-MEASURED check done rather than assumed: `tsc -p tsconfig.test.json --listFiles` hits the new pin file 1 time and ObjectCalendar.tsx 1 time, so typecheck really covers the new test.\n(4) `node scripts/check-changeset-presence.mjs` -> its own line: `2 source file(s) of 1 released package(s) changed, and this change declares 1 changeset(s): .changeset/6453-calendar-expand-gate.md.` `node scripts/check-changeset-no-major.mjs` -> `No changeset declares a 'major' bump.`\n(5) Control-byte self-scan over all three touched files: `grep -naP '[\\x00-\\x08\\x0b\\x0c\\x0e-\\x1f\\x7f]'` -> exit 1, no matches.\n\nMEASUREMENT (before the fix existed). Instrumented probe rendering the real ObjectCalendar standalone with dataConfig.provider==='object'; rows tagged with the query that produced them; observations read from the DOM (MutationObserver over container.textContent) and from real child commits (useEffect inside the CalendarView double), never from a last-delivery proxy. Three latency profiles x three adapter cases.\n A origin/main : 1 find, $expand null in ALL profiles. Final DOM `Site visit|raw|acct=\"acc-1\"`. getObjectSchema=1. Timeline shows find:issued BEFORE schema:issued.\n B objectSchema in deps : 2 finds, [null, ['owner','account','parent_visit','line_item']]. schema-slower(find=20,schema=60): DOM:LOADING -> raw@30ms -> DOM:LOADING@71ms -> expanded@94ms (three-step). equal(30,30): child:COMMIT[raw]@71ms but the raw and loading commits coalesced — a coin flip. schema-faster(find=60,schema=10): NO child:COMMIT[raw] at all — discarded on arrival.\n C gated : 1 find carrying $expand first, ALL profiles; single child:COMMIT[expanded] at 107/88/78ms; no-getObjectSchema -> 1 unexpanded find, paints at 37ms; schema-rejects -> 1 unexpanded find, paints at 66ms. Neither waits forever.\nRegime B's mutation was proven on disk, not by an editor exit code: deleted-text count 1->0 and injected-text count 0->1 by `grep -cF` on both strings, with an explicit ANCHOR-MISS abort. Restore proven by `git hash-object` == `git rev-parse HEAD:<path>` plus an empty `git diff HEAD`.\n\nREVERSE VERIFICATION — direction PREDICTED BEFORE THE RUN: 6 red, 3 green (pins 1,2,3,4,6,7 red). OBSERVED: `Tests 6 failed | 3 passed (9)` — the same six. Real excerpts:\n - `AssertionError: expected 'Site visit|raw' to be 'Site visit|expanded'` (the defect in one line)\n - `AssertionError: expected [ 'find', 'schema:issued' ] to deeply equal [ 'schema:issued', 'schema:settled', 'find' ]` (proves the query goes out before the schema is even requested)\n - `AssertionError: expected [] to have a length of 1 but got +0` (x3 — the expanded call never happens; including the object-switch pin, where the base sends visit's expand set at note)\nThe fix was COMMITTED FIRST (cf2728e68) so the restore had a real commit to return to. Mutation = restoring the file to the PINNED BASE b0236259e (never the moving name origin/main, which sibling agents advance). Mutation proven on disk by BOTH directions of text (fixed-text 1->0, base-text 0->1) AND by blob identity: worktree `git hash-object` == `git rev-parse $BASE:<path>` = 7f97229e364. Restore proven the same way against HEAD (45ccff06a94) plus an empty `git diff HEAD`, under `trap ... EXIT INT TERM` holding ABSOLUTE paths derived from `git rev-parse --show-toplevel`. The restore leg used `git checkout HEAD -- <path>`, never a bare `git checkout -- <path>`.\nNO DIST REBUILD APPLIES TO THIS LEG, and that is a fact about this repo rather than a skipped step: the root vitest.config.mts aliases every @object-ui/* specifier to packages/*/src (lines 255-275), so the tests never resolve through dist/ and a stale build cannot make a mutation leg read green. The dist build (step 1 above) is required only for `tsc`, which resolves through package exports, and it was run first for exactly that reason.\n\nPINS THAT STAY GREEN IN BOTH DIRECTIONS, and why they earn their place (also stated in the test file's own docstring, which I CORRECTED after the reverse run — it had claimed the REJECTS pin was non-discriminating and the measurement showed otherwise):\n - 'adapter exposes NO getObjectSchema': cannot discriminate against the base, which has no gate and queries here anyway. It guards a FUTURE wrong shape — it goes red the moment anyone simplifies the gate to `if (!objectSchema) return;`.\n - 'inline value data set' and 'hosted calendar takes rows from the parent': controls proving this change turned neither composition into a fetching one; the first is also the deadlock pin for the provider-scoped gate.\n - NOT in this list, contrary to my first draft: the REJECTS pin, whose ordering assertion is discriminating.\nGHOST-ASSERTION GUARDS: every count is reached only after waiting for a real call; test 1's `waitFor` targets the EXPANDED call specifically, so zero fetches TIMES OUT rather than reading as success; $expand is asserted against the fixture's expandable fields derived through core's own EXPANDABLE_FIELD_TYPES in BOTH directions (4 expandable present, 3 plain absent) rather than a hand-copied list; and rows are asserted to actually reach CalendarView.\n\nLINT — NARROWED, AND THE NARROWING IS MEASURED (three pieces, all present):\n (i) Population read from ESLINT'S OWN CONFIG via `ESLint#isPathIgnored`, not from my guess about which files count: 3808 of 3809 tracked lintable-extension files are selected.\n (ii) Files actually linted here, counted from `--format json` output: 22 — the whole packages/plugin-calendar package (a superset of my 2 changed files). ESLINT_PKG_EXIT=0, 0 errors, 118 warnings; my two files carry 0 errors (67w on ObjectCalendar.tsx under --no-inline-config, 14w on the test file). The 66w->67w delta versus an earlier run is --no-inline-config re-enabling one PRE-EXISTING `eslint-disable-next-line react-hooks/exhaustive-deps` at line ~198 that I did not touch.\n (iii) Invariance: `parserOptions.project`, `parserOptions.projectService` and `EXPERIMENTAL_useProjectService` all resolve to null for this file, so TYPE-AWARE LINTING IS NOT ENABLED. Every rule verdict in this config is file-local, so a 2-file diff cannot move the verdict on any of the 3786 files outside the narrowing.\nWhy narrowed rather than full: the repo-wide `eslint . --no-inline-config` does not fit this container's ~10-minute foreground cap alongside the shared verify-lock queue — one attempt was SIGTERM'd at exactly 10m (exit 143) after an 8m02s lock wait. CI runs the farm regardless. Reported as a measured narrowing, not as a run.\n\nTWO INVOCATION TRAPS HIT AND CORRECTED, reported so neither reads as a gate result: a `/usr/bin/time` that does not exist in this image (exit 127) and a `require('eslint')` resolving against the scratchpad instead of the repo (MODULE_NOT_FOUND, exit 1). Both are mis-pathed invocations that never reached the tool body; both were re-run correctly and are excluded from every count above.", "open_questions": [], "out_of_scope_findings": [ "filed as #6481 (Bug): ObjectTree's schema-settled latch is a bare boolean never keyed by object, so the query fired right after an object switch carries the PREVIOUS object's $expand set — same family as this card, keying half rather than missing-gate half. Its `finally` correctly settles every exit, so it does NOT carry the wait-forever hazard. Read from source, not measured; the card says so and asks the implementer to measure that component's own dependency set.", "filed as #6482 (finding): the schema-settled gate is now FOUR hand copies (kanban #6271, view #6419, calendar #6453, plus tree #6014's divergent two-state variant), and four more views — plugin-gantt:536, plugin-map:708, plugin-timeline:208, plugin-list/ObjectGallery:354 — resolve the schema but only list it in the deps rather than gating on it, so they carry regime B's cost. Carries the convergence question and the divergence evidence behind this PR's third-copy decision.

ACCEPT — PR #6484, head
6b1f48ba0. Verified against the tree.⭐⭐ The measurement spans both prior verdicts, and that is why it had to be taken here
The charter demanded measuring this component rather than inheriting #6419's or #6271's answer. It turns out this component's regime depends on relative latency and covers both:
objectSchemain the depsLoading calendar…→ expandedThe three-step is worse than the view's two-step for a concrete structural reason the dev found rather than assumed:
loadingis an early return that replaces the whole grid, and the re-run callssetLoading(true). So the user watches content, then a placeholder, then content.Gating is the only shape correct in all three profiles. Neither sibling's measurement could have established that, which retroactively justifies the "measure-first, do not inherit" charter across this whole family.
And
origin/mainwas measured too, not just reasoned about: 1 find,$expandnever present in any profile,find:issuedbeforeschema:issued. The defect is not latency-dependent; only the cost of the wrong fix is.The third hand copy — the right call, declared, with the evidence
I handed this decision over deliberately and it came back argued rather than asserted. The resolution half is genuinely common; the gate half is not:
dataConfig.object ?? schema.objectName, notschema.objectName.:306—if (dataConfig?.provider === 'object' && !objectSchemaReady) return;), not the whole effect, because an inlinevalueset issues no metadata read at all and a whole-effect gate would hold its query open on a resolution nothing was ever going to produce. That is a deadlock, and there is a pin for it.Plus the cost I asked to be weighed: a shared helper would be a new export on the published
@object-ui/react— AGENTS.md bars React from@object-ui/core— so a permanent public-surface widening, while refactoring two already-landed fixes inside a bug PR. #6482 asks the convergence question deliberately instead.Clause-②: no public surface change, and measured rather than inferred —
git diff -U0 | grep '^[+-].*\bexport\b'is empty and no entry file is in the diff.⭐ The family is closed, with a positive sweep
#6482 does the thing this seat's catalogue keeps asking for — "ask are there others, not did one merge" — and answers it in the direction that closes the question: every
buildExpandFieldscall site in the repo was swept, and the four other views that resolve a schema already have it in their fetch effect's dependency list. So none of them carries the never-expands defect, this family is closed at three members, andObjectCalendarwas the last one. That is worth more than the fix.Those four still pay regime B's cost, and #6482 records it without conflating it with this defect. #6481 (ObjectTree's unkeyed boolean latch) is correctly marked read from source, not measured, and hands the measurement obligation to its implementer.
Three pieces of discipline worth naming
The dev corrected its own docstring after the reverse run. The draft had claimed the REJECTS pin was non-discriminating; the measurement showed otherwise, and the file was fixed rather than left with a comfortable claim. Self-correction against your own draft is harder than catching someone else's.
The mutation restored to the pinned base
b0236259e, never toorigin/main. That is exactly right and worth recording as a general rule:refs/remotes/*is shared across every worktree, so a sibling agent's fetch movesorigin/mainunder you mid-ablation. Pin the base by SHA before you mutate.Two invocation traps were reported so neither could read as a gate result —
/usr/bin/timeabsent from the image (exit 127) andrequire('eslint')resolving against the scratchpad (MODULE_NOT_FOUND). Both are mis-pathed invocations that never reached the tool body, both excluded from every count. A non-zero exit that never ran the tool is not measured, not red.Lint was narrowed and the narrowing measured three ways, including taking the population from eslint's own
isPathIgnoredrather than a guess, and explaining the 66→67 warning delta as--no-inline-configre-enabling a pre-existing disable comment.Enqueue held on CI: 29 checks, 0 failed, 8 pending.
