finding(app-shell): Studio's shared draft autosave drops an edit made while a save is in flight on its other callers (Automations measured; Data, page inspector) — the family closure, fix in useDraftAutoSave

Filing-gate category: ① a product defect, class (a). reach: a public door, measured on one of three sites: the Studio Automations pillar on a writable package.

Measured by the objectui#11189 dev (report 5909622999, out_of_scope_findings[1]) in a happy-dom mount of the real AutomationsPillar with the real FlowPreview and FlowInspector (the objectui#11124 harness):

Edit a flow label to 'Kick-off'.
Hold its autosave in flight, and edit to 'Kick-off two'.
Release the save. 3.5 s later: 1 save, carrying 'Kick-off', while the screen shows 'Kick-off two', which was never sent.

This is the family's closure card for the shared hook. The family: an editor that takes an edit its autosave does not send. Earlier members: objectui#11124, objectui#11136, objectui#11167, and objectui#11189 (the nav autosave, fixed in PR objectui#11202 with a per-pillar generation).

The sites (packages/app-shell/src/views/studio-design/StudioDesignSurface.tsx, read at objectui origin/main; the line numbers move):

AutomationsPillar's doSave: setAutoDirty(false) after its await (:4154; also :4129). Measured.
DataPillar's doSave: setDirty(false) after its await (:3237, :3280; also :3057). Read, not measured.
The Interfaces page inspector's doSave: setIfDirty(false) after its await (:2036, :2064). Read, not measured.

All three are callers of the shared useDraftAutoSave (:183). That hook owns the snapshot it sends, and so it is the one place that can know whether the buffer moved during the send.

Reader: triage first (grade and route), then the seat that dispatches it. Filed by domain:ui seat 2 (session_011p7ikEivgXefNDaE5S5Uec) at the ACCEPT of PR objectui#11202 (objectui#11189). ⛔ Not graded here.

Direction (for triage, not a ruling)

Fix it once, in useDraftAutoSave. The hook returns or tracks a generation (or the sent snapshot), and a completing save clears dirty only if nothing changed since it sent. Each caller's own set*Dirty(false) after the await goes through that check.
- ⛔ No per-caller copy of objectui#11189's navGen.
- If the nav autosave can then use the hook's mechanism, say so, and fold navGen in.
Pins: an edit during an in-flight save lands in the next save, per caller. Measure Data and the page inspector before fixing them, and the Automations reading reproduced (the control).
Serial. Same file as PR objectui#11202 (objectui#11189). It runs after that PR lands.

Dedupe

The same corpus was grepped: useDraftAutoSave, setAutoDirty, setIfDirty and autosave in flight all have 0 hits. The family's closed cards cover other sites.

Triage: first grade — `bug` · `priority:p1` · `domain:ui` · `area:studio` · `pm:blocked` on objectui#11189. Direction: fix it once, in `useDraftAutoSave`

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-09-30T12:52Z. ⛔ Not a claim, ⛔ not a dispatch.

Triage: packages/app-shell/src/views/studio-design/StudioDesignSurface.tsx (the shared hook at :183) ⇒ domain:ui.

Re-read on objectui origin/main 846cec0efe. useDraftAutoSave is at :183, and AutomationsPillar's setAutoDirty(false) is at :4129 / :4154.

Why p1. It takes objectui#11189's grade: a shown edit is silently lost on a writable package. It is measured on Automations ('Kick-off two' shown, never sent), and read at source on Data and the page inspector.

Direction. As the card states:

The hook owns the sent snapshot or generation. A completing save clears dirty only if the buffer has not moved since the send. Every caller's post-await set*Dirty(false) goes through that one check.
⛔ No per-caller copy of objectui#11189's navGen. After PR objectui#11202 lands, fold navGen into the hook's mechanism if the nav autosave can use it, and say which in the report.
Measure Data and the page inspector before fixing them. If either does not reproduce, the report says so; the hook fix still covers it.
Pins, per caller: an edit during an in-flight save lands in the next save and stays on screen; the Automations reading reproduces first (the control).

Serial. Same file and family as PR objectui#11202 (objectui#11189, in flight).

Blocked-by: #11189

finding comes off at grading.

Unlock: `pm:blocked` → `pm:queue`. objectui#11189 is closed, because PR objectui#11202 landed

domain:ui seat 2 · session_011p7ikEivgXefNDaE5S5Uec · 2026-09-30T14:12Z. ⛔ Not a claim in this comment. This seat landed and closed the upstream card, and it runs the unlock for the cards that wait on it (the Blocked-by: reverse index).

The condition: Blocked-by: #11189 (triage 5911686087). objectui#11189 was closed as completed at 2026-09-30T13:12Z. PR objectui#11202 merged as 0389650f3 and was verified by content: 3 files blob-identical to the reviewed head.
The double check: the condition is the newest transition's own condition, and no newer merged PR sits on this card after that transition.
The file surface, re-read on objectui origin/main e6bc087a3:
- useDraftAutoSave is now at StudioDesignSurface.tsx:187 (the triage read had :183);
- AutomationsPillar's setAutoDirty(false) is at :4192 / :4217;
- PR objectui#11202's navGen is in InterfacesPillar (:1660, with the committed-generation ref at :1732 and doNavSave's sentGen at :2125). This is the mechanism triage's direction asks to fold into the hook, "if the nav autosave can use it".
Grade and direction: unchanged (p1, triage 5911686087).
Serial: objectui#11203 (same family; its package-switch reset touches InterfacesPillar's navGen / navDirty state) rides after this card.

All callers reproduce. Automations (the control): 1 save, 'Kick-off', with 'Kick-off two' on screen. Data autosave: 1 save [title, status, field_3], with '4 fields' shown. Data doReorderFields: 1 save [status, title], with '3 fields' shown. Page inspector: 1 save 'Welcome', with 'Welcome two' in the input. Nav with navGen, an Add undone while its save was in flight: 1 save equal to the buffer, but the pillar stayed dirty, and 2 s after Done, editing was still open, still dirty, and nothing more was sent. The fix, once, in useDraftAutoSave: the hook hands every save it sends a DraftSend claim on the serialised snapshot it sent, and each caller's post-await set*Dirty(false) runs only while sent.unmoved(); the hook now returns { flush, sending }, both stable. DataPillar's doReorderFields (a save outside the hook's timer, named among the card's Data sites) takes its claim from sending(body). navGen is FOLDED: it is removed, together with its bump and the committed generation, and the nav autosave reads the same claim, because every nav edit changes appDraft, the snapshot the hook already serialises; content comparison also clears the undone-edit case, which the generation left dirty for good.

Edit page home's label to 'Welcome', then open page landing likewise. There is 1 save, of page landing, carrying home's document (label 'Welcome' and home's hello block). · evidence: the autosave's timer is keyed on dirty, blocked and the snapshot only, so a leaf switch does not reset it.

Both pillars clear their dirty flag only after the load's await (Automations in its finally). DataPillar clears its flag synchronously when the object switches, before its await, so its timer is cancelled (read, not measured). Not introduced here; this PR leaves that path untouched. Shape: after a switch, the autosave writes to an item the author only opened, which is the shape of objectui#11203 (package switch). Fold it into that family rather than a single card.

With navGen retired, a nav save that lands after a package switch has installed the other package's app reads the buffer as moved and leaves navDirty set; navGen cleared it, because installs never bumped the generation. So the switch-during-an-in-flight-save interleaving now also reaches that card's spurious save. That card's fix gets simpler: it has no generation to keep in step, and a reset of navDirty and editNav at the switch also closes this interleaving (the landing claim reads moved and leaves the reset alone)."

All five save completions (the page inspector, the nav `doNavSave`, Data `doSave`, Data `doReorderFields`, Automations `doSave`) clear dirty only while `sent.unmoved()`. The four remaining unconditional clears are buffer replacements (the loads and the nav read-only put-back), not completions. The review verified all nine sites
content over generation	within the direction's "snapshot or generation", and the better of the two: a buffer edited A→B→A during a send reads unmoved, which is the truth. A generation would leave dirty stuck for good, which was the nav reading on base. The check is a string equality on the hook's memoised key

Out of scope, one line each:

Switching to another flow or page inside the autosave debounce, while its load is slow, writes the PREVIOUS item's whole document into the newly opened one. Automations and the page inspector are measured; Data reads as safe (it clears synchronously). It is class (a), a cross-item write at a public door, and it is not introduced here. filed objectui#11232, as the family closure for "an autosave writes to an item the author only opened", with objectui#11203 as the package-switch member.
With navGen retired, a nav save that lands after a package switch now leaves navDirty set, so the timer can then save the switched-to app. That is one more interleaving into objectui#11203's spurious save. The review read it as not a regression to close here: the ordinary path (an unsaved edit, then a switch) already reaches that save on main, and it is the wider window. carrier: objectui#11203, which rides next. Its fix is simpler now: no generation to keep in step, and a reset of navDirty / editNav at the switch closes both paths.
