Move skill discovery and transcript preparation off the input and render paths. Reuse indexed snapshots for menu queries and full transcript viewports. Read authentication presence without loading stored secrets. Add a ReleaseSafe percentile gate for the affected surfaces.

Resolve the Security.framework metadata lookup at runtime so Linux-hosted macOS cross-target builds do not require framework SDK paths.
Keep installed full transcript pages borrowed across frame commits, reject stale static revisions, and retain a valid live page while its replacement is building.
Keep the PGSO production manifest expectation synchronized with the opt-in terminal performance test exclusion.
Retain the last prepared page while a visible full transcript refreshes, without relaxing exact-revision requirements for an initial static open.
Retain the last prepared page for the duration of an open full-transcript session while newer content is prepared, preventing loading frames from replacing the reader's selection.
Fence skills and authentication actions on current background generations, protect catalog readers, and bound Ctrl-O preparation to reusable viewport windows. Strengthen performance and stress oracles so stale first paint cannot satisfy content-ready budgets.
Allow six temporary descriptors during the active resource phase while continuing to require an exact return to the pre-action descriptor baseline.
Permit legitimate multi-megabyte command descriptors in the immutable page handoff while keeping retained prepared windows capped. Wait for actual Ctrl-O readiness before asserting alternate-screen cancellation.
Use the bootstrap or host-provided skill catalog for WASM prompts instead of requiring a native HOME-backed filesystem refresh.
Fix background page ownership, auth presence, overlapping skill actions, pending Ctrl-O input, and replacement rendering. Expand percentile coverage to modal, catalog, manager, and hosted-terminal surfaces.
Queue both commands in one terminal transaction and keep the overlap flow as a focused always-on E2E regression.
Retain percentile and timeout evidence for direct tmux panes without treating capture-process scheduling as fx frame latency.
Defer restored child readers until their exact page is ready, retain the saved visual offset, and repaint only same-width prepared pages during replacement.
Use the 1 ms cadence for pending opens and scroll-window refills while live full-transcript refresh keeps the normal bounded event-loop cadence.
Freeze the installed full-transcript page while command output is active, but build one current page for an explicit pending open and refresh after completion.
