The pre-flight auth check in resolveModelOverrideWithAuthFallback called
getApiKey without a session id. For providers with session-sticky OAuth
credentials, this returned undefined even though the credential was
usable once the subagent session started, causing the auth fallback to
silently replace the configured model with the parent's (#5325).
The subagent's id is now forwarded as the session id so session-sticky
credentials resolve during the pre-flight check. Genuinely broken auth
(stale OAuth, revoked tokens) still falls back as before.
Also propagate model resolution warnings through resolveModelOverride
and log them in the executor so users see why a pattern didn't match.
- Exported ensureChromiumExecutable so the test can probe launchability.
- CI runner holds the downloaded Chrome but lacks libnspr4 & co., so the
binary fails at dynamic-link time; probe --version and skipIf instead
of failing the release run.
- Added `tui.scrollbackRebuild` configuration with interactive startup/controller wiring to apply `setScrollbackRebuild`.
- Exposed prewalk session state in `SegmentContext` and rendered a dedicated prewalk segment/icon in the status line.
- Added divergence-aware TUI full-paint logic that enables scrollback erase-and-replay rebuilds for non-multiplexer divergence cases.
- Updated rendering and streaming tests to verify rebuild behavior (`3J`) and eliminate stale marker expectations under drift scenarios.
- Replaced legacy `pi/` role alias prefix with canonical `@` syntax across model resolution, documentation, and tests.
- Added support for bare `*` default alias and multiple alias prefix detection with custom role resolution in `resolveConfiguredRolePattern()`.
- Enhanced thinking suffix parsing to accept unambiguous abbreviations (minimum 2 characters) for effort and level selectors.
- Extended `resolveCliModel()` and `filterAvailableModelsByEnabledPatterns()` to accept settings parameter for role alias resolution from `--model` flag.
- Changed daemon log reads to return both sanitized display text and a raw `terminalText` slice, and included it on log RPC responses for PTY runs when grep was not used.
- Extended the logs result contract and launch tool rendering to consume `terminalText`, reconstruct terminal output, and display it in framed, preview-capped sections.
- Kept terminal row layout stable by writing space characters for empty cells when reading rows, preserving spacing during output reconstruction.
- Bounded expanded partial edit diff rendering in `formatStreamingDiff` to `previewWindowRows()` instead of an unbounded budget, preventing runaway preview growth during live updates.
- Updated streaming diff tests to simulate terminal height and verify expanded previews stay full only within the viewport, then switch to a truncated tail with the `more lines above` marker when too tall.
- Reinitialized in-memory `Settings` before each initial-messages test since the test suite reads global display configuration and needs isolation.
- Added `isAcceptedElicitation` in the ACP agent to narrow accepted elicitations before accessing response content.
- Added `isFormElicitation` in ACP tests and used it to narrow form-mode requests before assertions.
- Initialized in-memory settings in the repro issue test by resetting settings before theme setup.
- Reduced the UI/TUI CI test bucket chunk size from 10 to 5 to avoid cumulative Bun GC heap aborts.
