After #5239 compaction, a later render only fills segments from
#compactedChildStart, leaving undefined holes in the prefix. Iterating
those entries crashed when retiring IRC/ephemeral cards
(`segment2.component`). Guard undefined segment slots and cover the
sparse-hole path with a red/green regression.

Addresses the second review round (internal re-review + Codex on c38840482):
- Active-account matching (logout preselection, /usage in-use marker) is
org-decisive when EITHER side carries an org: a legacy bare-email active
row no longer flags org-scoped siblings via the shared email (reverse of
the previous fix). Both-org-less keeps the email/account fallback, so
providers without orgs are unaffected.
- Status-line usage context key includes orgId, so rotating between two
same-email subscriptions invalidates the cached quota immediately
instead of showing the previous org's numbers for the cache TTL.
- CredentialHealthResult carries orgId/orgName and auth-gateway check
labels rows with the org, so a failing row names the subscription.
- getOAuthAccountIdentity preserves org-only identities; the login
success message renders them.
- ACP /usage account-id fallback labels get the org suffix too.
- Regression tests for both matching directions (marker + logout).
- Implemented custom role creation within the Model Hub, including a virtual row for direct initiation and name stripping.
- Added quick-switch cycle editing functionality with persistent ordering and live preview of role membership.
- Optimized sidebar scope navigation to mute empty entries and improve keyboard focus stability during search.
- Updated the Model Hub sidebar UI to prioritize Roles and included comprehensive tests for new navigation and management flows.
- Implemented dynamic reordering of model providers in the sidebar to prioritize matches during active searches.
- Refactored model hub registry synchronization to maintain separate state for fixed, unlocked, and locked provider entries.
- Added a dedicated composition step to reassemble sidebar entries based on current search result counts.
- Added test coverage to verify that provider order reverts to alphabetical upon clearing the search query.
- Enable horizontal navigation between the scope sidebar and model list using left and right arrow keys.
- Update UI help strings to reflect the new spatial navigation controls.
- Replaced the legacy model selector with a full-screen Model Hub, introducing mouse support and a fuzzy-searchable browser.
- Integrated comprehensive model management, including role assignment, thinking-level visualization, and manual provider discovery.
- Implemented a cancellable OAuth login flow and integrated it directly into the Model Hub for provider authentication.

- Added a focused EventController regression test for text/toolCall/text Cursor-shaped turns.
Fixes#4871

Rendered the /move directory picker using the overlay layout width instead of the legacy fixed 68-column frame.
Added regression coverage for non-68-column overlay frames.
Fixes#5067
Reset the ask tool fallback timeout whenever the interactive selector resets its UI countdown, preventing late keypresses from falling back to the original recommended option.
Refs #4995
- Added auto-sealing logic to `FinalizableBlock` to finalize displaceable snapshots when they enter the scrollback area.
- Updated TUI frame emission to publish committed rows and clamp them to segment bounds, ensuring accurate component updates.
- Introduced component tracking and cleanup in event controller tests to prevent resource leaks during finalization.
- Validated state transitions and post-emit synchronization through comprehensive new test suites for transcript and TUI components.
The first-result viewport-repaint gate assumed only streamed
__partialJson placeholder shapes (SSH) could re-anchor; the write
renderer's collapsed pending preview paints a tail window from decoded
content, so its first partial result re-anchored to the top of the file
and left the committed tail rows stale above the new frame.
Resolve forceFirstResultViewportRepaint per renderer as a boolean or an
(args, options) predicate evaluated at paint time: write opts in when a
collapsed preview outgrew the streaming tail window, SSH stays scoped to
the streamed-placeholder shape it always covered.
Adopted from PR #4478 (roboomp) with an allocation-free line-count scan
and terminal-buffer regression coverage.
Fixes#4477
The v16.3.12 explicit `selector` field (ff3b0c795c) was consumed by the
read tool but never threaded into the TUI renderers: ReadRenderArgs in
both readToolRenderer (read.ts) and ReadToolGroupComponent only derived
selectors from path-embedded `:sel` suffixes, so split-arg calls like
{ path, selector: "2-3" } rendered bare paths without line ranges or
raw modifiers.
Joined the explicit selector (trimmed, leading colons stripped, non-string
guarded) back onto the display path in renderCall, renderResult error and
success branches, and the grouped read summary, keeping hyperlinks on the
base path only.
Adopted from PR #4904 (both commits squashed), minus its unrelated
workflow-notice.md prompt churn.
Fixes#4899
