finding(app-shell): Studio's Interfaces rail keeps nav editing open after the package answers read-only, so edits are taken on screen and never saved

[objectstack-fleet]

Filing-gate category: ① a product defect with a named site, class (a). reach: a public door, measured: the Studio Interfaces rail's Edit toggle.

• The sequence. The toggle is clicked while the surface's package-list request (GET /api/v1/packages) is still in flight, and the request then answers writable: false.
• Measured. The objectui#11153 dev ran an uncommitted probe on PR objectui#11164's harness: a happy-dom mount of the real StudioDesignSurface, with the package list resolved by hand after the click. After the read-only answer the toggle hides, but nav editing stays open: AppNavCanvas with "Add nav item" remains on screen. The nav autosave is blocked on readOnly, so edits are accepted on screen and never sent. The probe ran once, in happy-dom, not in a live browser.
• Confirmed at source. PR objectui#11164's contract review (5902516373, ③ out-of-scope (a)) confirmed it real at the head and pre-existing. It also found that PR objectui#11164 neither improves nor worsens it.

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#11164 (objectui#11153), from the dev report's out_of_scope_findings[0] (5902396944). It is the objectui#11124 / objectui#11136 class: an editor that accepts edits its autosave will not send. ⛔ Not graded here.

The site (read at PR objectui#11164's head c262d51ee, packages/app-shell/src/views/studio-design/StudioDesignSurface.tsx; re-read by content after it lands)

• The toggle renders under appStatus === 'ready' && !readOnly. readOnly is pkgWritable === false, which is false while the package list is in flight.
• editNav is turned off only by the toggle's own onClick. Its other writer, the deep link's apply, only ever sets it to true.
• The nav autosave is blocked: … || readOnly.
• The result. A click inside the window, then a read-only answer, hides the toggle, leaves the canvas open, and blocks every save.

PR objectui#11164 makes pkgWritable tri-state: undefined while asking, and null when it could not find out. A fix can therefore tell "still asking" from "answered".

Direction (for triage, not a ruling)

• When readOnly becomes true, nav editing closes, for example an effect that sets editNav to false on the transition. Alternatively, the toggle is withheld until the write state settles.
  • PR objectui#11164's whole-surface race pin asserts the toggle is on offer while the state is unsettled. That is the surface's documented "unknown writability stays ungated" contract, so withholding the toggle would loosen that one assertion.
  • Closing on the transition keeps the contract.
• Pins:
  • Edit clicked while the list is in flight, then writable: false: nav editing closes and no edit is left on screen unsaved;
  • writable: true: editing stays open (the control).

Dedupe

The 1000 most recently updated objectui issues and PRs (down to #10338) were grepped:

• pkgWritable and nav autosave: only PR objectui#11164 (the source).
• editNav: PR objectui#11164, objectui#11153 (the deep link), PR objectui#11152 (page inspectors' readOnly, a different editor), and PR objectui#10617 (an unrelated key list).
• Edit navigation: 0 hits.

No card covers this.

Path: studio — a read-only package offers no edit it will throw away | 缺项 (Edit clicked while the package list is in flight, then writable: false: the toggle hides, but nav editing stays open and its autosave is blocked, so edits are taken on screen and never saved) | P2

Triage: first grade — bug · priority:p2 · domain:ui · area:studio · pm:queue. Direction: nav editing closes on the transition to read-only. That keeps the surface's "unknown writability stays ungated" contract

Triage: lands in packages/app-shell/src/views/studio-design/StudioDesignSurface.tsx ⇒ domain:ui. It is the objectui#11124 / objectui#11136 class.

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-09-30T02:54Z. ⛔ Not a claim, ⛔ not a dispatch.

Why p2. It takes objectui#11124's and objectui#11136's grade (p2): an editor that accepts edits its autosave won't send, so an author's work is silently lost. It is reached only inside the in-flight window of the package-list request, which keeps it below p1.

Direction.

• Close on the transition. When readOnly becomes true, nav editing closes. editNav goes to false on the transition, so no canvas is left open that accepts edits its autosave will refuse.
• Keep the toggle's contract. ⛔ Don't withhold the toggle until the state settles. That would loosen PR objectui#11164's documented "unknown writability stays ungated" race pin. The card's own analysis prefers the transition, and so does triage.
• One writer. The deep link's apply (objectui#11153) and this transition both read readOnly through the same flag. ⛔ No second read-only mechanism.
• Pins:
  • Edit clicked while the list is in flight, then writable: false: nav editing closes, and no edit is left on screen unsaved;
  • writable: true: editing stays open (the control);
  • PR objectui#11164's race pin stays green.

Serial. It sits on PR objectui#11164's tri-state pkgWritable (objectui#11153, ACCEPTed and still open), so it is dispatched after that PR merges. The same file carries objectui#11158 (queued): whichever lands second rebases.

When readOnly is true, open nav editing closes the way the toggle closes it: editNav goes false and navSel null, which is the toggle's whole close path, and the nav-item inspector goes with them. A dirty nav buffer is put back to the document as last loaded or saved (navBaselineRef) and navDirty is cleared, so no edit stays on screen that a read-only package refuses. The toggle stays on offer while the write state is unknown. The effect is declared before useNavSelDeepLink, so a pending ?sel=nav: link settled by the same answer keeps its read-only selection. The deep-link apply was already gated: it waits while readOnlySettled is false and applies with enterEditing = readOnly === false. Five pins: three read-only cases and two writable controls. objectui#11164's race-pin file is byte-unchanged and green. Each of the two ablation legs turns exactly the predicted pins red. The PR assignee write was refused by the auto-mode classifier and is left to the seat (see deviations).",

(2) The closure build, pnpm exec turbo run build --filter='@object-ui/app-shell^...' --concurrency=2, gave exit 0 with Tasks 28 successful, 28 total. Then pnpm --filter @object-ui/app-shell type-check (tsc --noEmit && tsc -p tsconfig.test.json, script name echoed) gave exit 0. tsc -p tsconfig.test.json --listFilesOnly lists the new pin file once; its first attempt was exit 99 queue-timeout, NOT MEASURED, and the retry on the same slot gave exit 0. (3) pnpm exec eslint on the 2 changed source files gave exit 0: 0 errors and 18 warnings. The same file at base also gives 18, each shifted by exactly the lines inserted above it, and the test file gives 0. (4) Ablation used objectstack scripts/ablation-replace.mjs in wrap mode with the fix committed first. The subject is imported by a relative path from src, so there is no dist leg. Each leg ran the new pin file plus the 11153 file. Leg 1 deleted the effect (anchor 1 to 0, blob c0bf6632f309 to 43df0da4beae): 3 failed and 8 passed, all three read-only pins red on navEditingOpen() staying true, both controls and all six 11153 pins green. Restore was proven: blob equals HEAD c0bf6632f309 and git diff HEAD is empty. Leg 2 moved the effect after useNavSelDeepLink (blob to ecc2a7c6b11b): 1 failed and 10 passed, only the pending-link pin red, on selParam(). Restore was proven the same way. A first leg-2 run also reddened the writable control. The cause was the test's server double returning a bare draft instead of the item envelope, so a re-read landing before the assertion fell back to the published layer. It was fixed in 7c7f285d5, and both legs were re-run from that commit; the numbers above are the re-run.",

Deviations, answered.

• The buffer put-back diverges from the toggle, which keeps a dirty buffer. It is right, and the card requires it: on a read-only package no autosave can reach the buffer, and keeping it would hold navDirty (the leave guard and the copilot refresh hold) for good.
• The three-key effect: right. It never clears a read-only deep-link selection.
• The PR assignee is unset. The dev's label-write --assign on PR objectui#11187 was refused by its session's permission layer. The seat does ⛔ not re-route a write a subagent's permission layer refused. It has been surfaced to the maintainer and is not a landing gate.

Out of scope, one line each:

• Two measured class-a sites in the nav autosave: (1) Done inside the debounce leaves the edit unsent; (2) an Add while a save is in flight is silently dropped. filed objectui#11189 as the objectui#11124 / objectui#11136 family's nav closure card, one card for both sites, as the review judged.
• No notice is shown when an unsaved nav edit is put back on a read-only answer: Acceptance notes. It is a residual, not a defect, and a toast needs new strings in every locale pack.

Next on this file: objectui#11181 and objectui#11189 both edit StudioDesignSurface.tsx's InterfacesPillar, so they run one after the other, after this PR lands.
