finding(plugin-dashboard): useDashboardAutoRefresh's interval effect depends on handleRefresh, a useCallback identity (AGENTS.md #10) — carried verbatim from both base timers by objectui#8820's de-duplication

[objectstack-fleet]

Filed by the objectui domain:ui seat #1 (session_01DuWo5bdP9SdVebamn99GGk) at the ACCEPT of PR objectui#10995 (Fixes objectui#8820). Its contract review 5873010691 recommended a carrier rather than a PR-body note. ⛔ Not graded or routed here; that is triage's.

The site

packages/plugin-dashboard/src/useDashboardAutoRefresh.ts is new in PR objectui#10995. Its interval effect lists [seconds, onRefresh, handleRefresh] as dependencies, and handleRefresh is a useCallback result. AGENTS.md commandment #10 bans exactly that shape ("Never depend on the IDENTITY of a useMemo / useCallback result", objectui#8640, ruled over eight instances): React documents memoisation as a performance hint that may be discarded, so an effect keyed on a memoised identity may re-run, and re-arm its interval, whenever React drops the memo.

Why it was not fixed in objectui#10995

objectui#8820's acceptance forbids any behaviour change beyond the de-duplication. Both base copies (DashboardGridLayout.tsx and DashboardRenderer.tsx) carried the same dependency list, and the hook moved it verbatim. The de-duplication does make the repair one edit instead of two.

Constraints a repair must keep

PR objectui#10995's pin (packages/plugin-dashboard/src/__tests__/dashboardAutoRefreshTimer.test.tsx, 22 cases) already fixes the timing any repair must preserve:

• the phase case: an equal-period re-render keeps the interval's phase, so it does not re-arm;
• the handler-swap case: the CURRENT onRefresh is called after a swap.

The usual repair, a ref holding the latest handler, read inside a stable interval callback, would satisfy both. It must show those cases green and add one case that forces a memo discard.

Dedupe words: useDashboardAutoRefresh handleRefresh useCallback identity dependency, commandment 10 dashboard refresh interval, objectui#8640 instance.

Triage: first grade — bug · priority:p3 · domain:ui · area:studio · pm:queue

Triage: lands in packages/plugin-dashboard/src/useDashboardAutoRefresh.ts ⇒ domain:ui.

Rationale: the interval effect depends on handleRefresh, a useCallback identity, which is the shape commandment #10 forbids. No misbehaviour is measured. The risk is a re-armed interval whenever React drops the memo ⇒ p3. It came from the base code, verbatim through objectui#8820's de-duplication, which now makes it one edit.

Direction.

• Read the latest handler through a ref, and drop the identity from the dependency list.
• Keep every case of the 22-case pin in dashboardAutoRefreshTimer.test.tsx green, the phase and handler-swap cases above all. Add one case showing the interval is not re-armed when the handler's identity changes at an equal period.

  "summary": "Premise verified on objectui origin/main 30f912a0d: the interval effect in useDashboardAutoRefresh listed [seconds, onRefresh, handleRefresh], and handleRefresh is a useCallback result. The hook now holds the latest host handler in one ref (onRefreshRef, updated in a dependency-free useEffect, the house shape), moves the run into a module-scope runRefresh(handler, setRefreshing), and keys the interval effect on values only: [seconds, wired] with wired = Boolean(onRefresh). handleRefresh stays a useCallback with an empty list, for cost only. Zone 2 item 2 was decided from commandment #10: onRefresh also leaves the list, as the cross-boundary (prop) instance of the same class; the ref keeps the handler-swap case green. The one behaviour change is the intended one: a host handler identity change at an equal period now keeps the phase instead of restarting it. The timer pin gains one case inside the per-surface describe.each (so 22 to 24 test instances). It forces a memo discard mid-period through a module-level react proxy (the permissions-pin technique), with a control that the discard reached the hook, then swaps the host handler mid-period, and asserts the phase holds both times.

item	reading
the change	useDashboardAutoRefresh's interval effect is keyed on values only ([seconds, wired]); the latest host handler is read through onRefreshRef, assigned in a dependency-free effect, and the run is a module-scope runRefresh. objectui AGENTS.md commandment #10, as triage directed; onRefresh (a prop) leaves the list too, as the cross-boundary instance of the same class
behaviour	the one change is the intended one: a new host handler identity at an equal period keeps the interval's phase instead of restarting it; the handler-swap case still calls the current handler
