Route overlapping executions through owned Shell instances so timeout and interrupt paths can explicitly abort native child-process cleanup.
Fixes#5389
- 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.
- Added a process-wide `__harborManagerHooks` flag on `globalThis` so signal and unhandled-rejection handlers are registered only once during Bun `--hot` re-execution.
- Added `isDevStreamTeardown` handling to ignore `ERR_STREAM_RELEASE_LOCK` unhandled rejections from dev stream teardown while rethrowing all other unhandled rejections.
- Added `react-refresh` to the Harbor Manager package manifest and lockfile dependencies.
- 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.
- Refined the coding-agent prewalk-plan system prompt to require 5-9 meaningful todo steps with concrete targets and verification, and removed the requirement for a super-detailed single-reply plan format.
- Added a `hot-reload-probe` marker comment at the end of Harbor Manager's `server.ts`.
- 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.
- Upgraded `@agentclientprotocol/sdk` from `0.25.0` to `1.2.1` and `@ark/schema` from `0.56.1` to `0.56.2` in `package.json` and `bun.lock`, updating `patchedDependencies` and override entries accordingly.
- Updated lockfile package metadata to match new manifest versions, including TypeScript `7.0.2`, arktype `2.2.3`, and several related dependency/version dependency-tree entries.
- Added a new `@agentclientprotocol/sdk@1.2.1` patch that extends the package exports with `./dist/schema/zod.gen.js` including type and default import mappings.
- Removed the Google Interactions transport and deleted interaction-specific request options from the shared AI stream typing/API surface.
- Simplified Google provider routing to eliminate interactions auto-selection logic and keep `streamGoogle` on the `:streamGenerateContent` path.
- Updated Vertex request handling to use resolved stream hosts without `/interactions`/`Api-Revision` and removed related interaction constants.

- Added system prompt templates and runtime checks to facilitate message handling for boomerang transitions.
- Included unit tests to verify context management and validation pass requirements during the boomerang process.
- Included the todo tool in downshift action triggers, gated on the plan nudge being in context — a post-nudge todo init is the planning-complete signal, while a turn-one todo remains bookkeeping.
