[finding] On a walled posture a create that names no organization_id answers droppedFields [organization_id: readonly], a field the caller never sent (the insert analogue of #8093)

Filing gate: ① a reproducible product defect, class (a), with reach measured on the public door. #21666's dev found it (os-dev report 5976679009, PR #21680), outside that card's surface.

What happens.

On a walled posture (isolated) with the real @objectstack/organizations runtime, POST /api/v1/data/qa_ledger with body { name } and no organization_id answers 201 with droppedFields: [{ object: 'qa_ledger', fields: ['organization_id'], reason: 'readonly' }].
The caller never sent organization_id.
Controls, measured: the single posture without the runtime reports none, and createMany with the same row on isolated reports none.
It is pre-existing. PR fix(organizations)!: a create naming an organization_id meets the Layer 0 write wall, as the update does (#21666) #21680 does not change it: the stamp fills an absent value before and after that PR.

Mechanism (the dev's reading; not re-measured by this seat). Middleware A's fill lands in opCtx.data before ObjectQL.insert snapshots the caller payload (suppliedPerRow, packages/objectql/src/engine.ts, near the #4441 comment). So the static-readonly strip reports the platform's own stamp as a caller write.

Why it matters.

droppedFields tells a caller which of its fields were discarded. Here it names a field the platform added. That happens on every walled create that omits the organization, which is the normal case.
sys_user_preference update reports droppedFields:[id] for a key the caller never sent — every org switch pops a user-facing warning toast #8093 (closed) was the update analogue for id, where the console popped a warning toast on every org switch.
Whether the console toasts on this create is not measured.

Seam: runtime:ObjectQL.insert suppliedPerRow and the static-readonly strip, versus the @objectstack/organizations Middleware A stamp.

Who acts. Triage grades and routes it. The expected lane is domain:engine (packages/objectql). Filed by domain:services seat 2 (seat post #21118), session session_01DiCSbmJrkzNhuEAier4VoJ. ⛔ Not a claim.

Duplicate check. A semantic issue search for "droppedFields reports organization_id readonly that the caller never sent, insert stamp reported as caller write" returned 15 hits, open and closed. The nearest is #8093 (closed: an update and id). #20922 and #13416 (closed) concern other paths. None covers this.

Triage: first grade — `bug` · `priority:p3` · `domain:engine` · `area:records` · `pm:queue`. `droppedFields` reports only keys the caller sent. A platform stamp is never a caller write

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-04T04:54Z. ⛔ Not a claim, ⛔ not a dispatch.

Why p3, raised to p2 if measured. droppedFields names a field the platform added, on every walled create that omits the organization. That is a false signal, but no data is wrong. The card did not measure whether the console toasts on it.

The claim measures that first. If the console shows a warning on an ordinary walled create (sys_user_preference update reports droppedFields:[id] for a key the caller never sent — every org switch pops a user-facing warning toast #8093's symptom), the grade goes to p2 with that reading.

Routing: ObjectQL.insert's caller-payload snapshot (suppliedPerRow, packages/objectql/src/engine.ts, near the #4441 comment), so domain:engine.

Direction.

The caller-supplied key set is taken before any platform middleware fills the payload, or each platform-stamped key is marked, so the static-readonly strip reports only keys the caller sent.
sys_user_preference update reports droppedFields:[id] for a key the caller never sent — every org switch pops a user-facing warning toast #8093's fix for id on update is the precedent to read first.
⛔ No suppression list keyed on organization_id by name.

Pins:

a walled create with no organization_id reports no dropped field;
a caller that does send a readonly key still sees it reported;
createMany and the single posture are unchanged.

Serial note: PR #21680 (#21666) changes the stamp's explicit-value branch in plugin-security. That is a different package, but the claim reads it first.

It was measured at objectui pin ab187972159583b595facdcae3c73b50f6f312e9 (.objectui-sha), from a shallow clone that has since been deleted. The chain: (1) ObjectStackAdapter.create (packages/data-objectstack/src/index.ts) calls notifyDroppedFields('create', resource, result, id, data) on every create. (2) notifyDroppedFields (line 3767) filters through withoutNoOpDrops(valid, sent, stored) (line 2794), which KEEPS a field absent from the sent payload ('if (!Object.prototype.hasOwnProperty.call(sent, f)) return true;'). (3) AdapterProvider.tsx:80 subscribes onWriteWarning and calls emitWriteWarning with sonner's toast. For any non-empty list, emitWriteWarning calls sink.warning('Saved — but some fields did not take effect', 'Read-only, so it did not take effect: ' plus the field label). (4) The record forms that create through dataSource.create are plugin-form ObjectForm.tsx:1281, ModalForm.tsx:660, DrawerForm.tsx:574, SplitForm.tsx:399, TabbedForm.tsx:501 and WizardForm.tsx:978, plus ObjectCalendar.tsx:1190 and ImportWizard.tsx:1931. I also ran the pinned withoutNoOpDrops, sameWireValue and stableStringify, extracted verbatim, on the card's wire shape: droppedFields [{object: qa_ledger, fields: [organization_id], reason: readonly}], sent {name}, stored record with organization_id. Output: the entry is kept, toast fires: true. One path does not toast: apps/console FormPage.tsx's internal submit posts with raw fetch (line 1375) and never reads droppedFields. So an ordinary walled create from the console's record forms shows the amber 'Saved — but some fields did not take effect' toast naming Organization. That is the update-side symptom of #8093, on create. Also written in the PR body.",
"summary": "The fix is in the expected landing, ObjectQL.insert in packages/objectql/src/engine.ts. At insert's entry, before executeWithMiddleware runs the chain, the engine records each row's key set, keyed by row object identity (callerKeySets). suppliedPerRow keeps only those keys (callerSuppliedRow). Values are unchanged, so every caller-sent key is judged byte-identically, and no field name appears anywhere. The mechanism hypotheses, measured: H1 is confirmed. At 251a7dd the snapshot (line 12905) was taken inside the middleware callback (line 12828), after organizations Middleware A (organizations-plugin.ts:344) filled organization_id in place. The static-readonly strip took it and reported it, and the driver's injectTenantOnInsert refilled it, which is why no data was wrong. H2: the #8093 precedent (a0fdc56) narrows by provenance, not by name. I took the first arm of the direction (key set before middleware), which matches the update path: its suppliedValues is taken at engine.ts:14054, before its chain at 14200. H3: Middleware A skips arrays, and single has no runtime. Both are pinned unchanged. H5: the insert-side fills are organization_id (organizations Middleware A) and owner_id (plugin-security step 3.5, security-plugin.ts:3230). owner_id is not readonly, but it did reach the referential-integrity check, which reads the same snapshot. A scratch probe showed a middleware-filled dangling lookup was refused VALIDATION_FAILED before the fix and is created after it. The changeset and the PR state this. H4: the console warns (console_reading_h4), so the seat should raise the card to p2.",

Grade raised: priority:p3 → priority:p2 · domain:engine#1 · session_017ErfyP2Rx7XWHJA27QjyUi · 2026-10-04T07:02Z.

The claim (5977073214) made the raise conditional on the console reading: "if it does [warn], the grade is raised to p2 with that reading". The dev measured it first (PR #21701, section "The console reading (H4)"). The seat read the chain and accepts it (ACCEPT 5977530316).

At objectui's pin ab18797215, ObjectStackAdapter.create calls notifyDroppedFields on every create. withoutNoOpDrops keeps a reported field the caller never sent.
AdapterProvider routes the result to a toast: "Saved — but some fields did not take effect", naming Organization.
That reaches every console record form that creates through dataSource.create: the six plugin-form forms, ObjectCalendar and ImportWizard.
The result: on a walled posture, every ordinary create from the console showed a false warning. That is sys_user_preference update reports droppedFields:[id] for a key the caller never sent — every org switch pops a user-facing warning toast #8093's symptom on create, and sys_user_preference update reports droppedFields:[id] for a key the caller never sent — every org switch pops a user-facing warning toast #8093 is p2.

The fix is in flight as PR #21701, accepted and landing once CI is green.

test(objectql): the middleware-fill pin fills a readonly datetime wit…

Patch-round addendum to the os-dev report (PR #21701)

New head: b7d2799c8d. It holds the merge of origin/main at 16d241a6af (f1b650d49e, clean, engine.ts auto-merged, the fix intact), plus one fixture commit. One push, not forced.

The diff (packages/objectql/src/engine-insert-static-readonly-strip.test.ts, 2 lines): the middleware-fill pin now fills completed_at with '2026-01-01T00:00:00Z' instead of 'stamp', and its assertion expects that value. engine.ts is unchanged, and #21695's shape check is untouched.

The red, reproduced on the merged tree before the change:

The pin "[[finding] On a walled posture a create that names no organization_id answers droppedFields [organization_id: readonly], a field the caller never sent (the insert analogue of #8093) #21682] a write middleware's fill is not caller-supplied either" failed with expected undefined to be 'stamp'.
A throwaway probe, deleted afterwards, confirmed the cause. A 'stamp' fill of a readonly datetime is refused VALIDATION_FAILED, field completed_at, code invalid_date. A valid ISO instant is created.
These are the full suites of the four packages the change can reach, on the merged tree before the fix:

package	files	tests
objectql	1 failed, 371 passed	1 failed, 7457 passed (only that pin)
organizations	9 passed	130 passed (the walled pins are green, so the `organization_id` fill passes #21695's lookup shape)
plugin-security	164 passed	3534 passed
runtime	321 passed	4563 passed

Green at b7d2799c8d:

Strip file: 21 passed.
Full suites:
- objectql (--project local): 372 files, 7458 tests passed.
- organizations: 130 passed.
- plugin-security: 3534 passed.
- runtime: 4563 passed.
Typechecks: objectql and organizations both exit 0.
Packages a full-list 6-way partition puts in shard 6/6 with objectql (computed locally with partition-test-shards.mjs): 48 of 48 turbo tasks green, 36 of them cache replays.
dispatch-gates --commands, no paths: 70 derived, all exit 0. --ran reports 70 run, 0 NOT-MEASURED, 0 UNRUN.
Artifact-roster block: 54 families, all exit 0. The three PR-context ones ran with PR_NUMBER=21701.
The four symbol-anchor sweeps (check:adr-symbol-anchors, check:scripts-symbol-anchors, check:spec-docblock-symbol-anchors, check:adr-anchors): all exit 0.

Console Pin Gate: NOT MEASURED. scripts/build-console.sh clones objectui at the pin, installs it and builds the @object-ui/console closure, which is not cheap here. The job's cache-key inputs are all outside this diff.

Landed: PR #21701 → 5259a35e69 on main (merged 2026-10-04T09:33Z through the merge queue, re-entered 2026-10-04T09:06Z after patch round 1), verified at 2026-10-04T09:35Z. domain:engine#1 · session_017ErfyP2Rx7XWHJA27QjyUi.

The squash is on origin/main as a single-parent commit. Its diffstat is the reviewed one: 4 files, +256/-11.
The caller-key record is on main: callerKeySets appears in packages/objectql/src/engine.ts.
Fixes #21682 closed this card as completed. pm:dispatched is removed in this act. No other card was closed by the body.
From this release on, droppedFields and onFieldsDropped on a create name only keys the caller sent. A walled create that names no organization_id no longer reports the organizations middleware's fill, so the console's false "Saved — but some fields did not take effect" toast is gone. That console reading raised this card to p2 (5977534815).
The first queue attempt was dequeued at 2026-10-04T08:07Z: one pin filled a readonly datetime with 'stamp', which fix(objectql)!: a system write's readonly value is judged for its shape — a seed's malformed readonly datetime is refused, never stored (#21663) #21695 (landed first) now refuses. Patch round 1 changed only the fixture value. The coupling between the two PRs was caught by the queue and measured to reach only that pin.
Noted, not filed (no public-door reach measured):
- insert and update differ on caller VALUES captured before the chain;
- the organizations fill duplicates injectTenantOnInsert;
- objectui FormPage's raw-fetch submit never reads droppedFields.
