- 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.

- 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.
- 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.

- Add `readTerminalRows` and `styleTerminalRow` in `tools/terminal-output.ts` to serialize terminal buffers while preserving safe ANSI styles.
- Update `broker.ts` to use standardized PTY dimensions and ensure terminal output is properly sanitized and well-formed during stream processing.
- Added an environment configuration option to choose between docker and apple-container backends.

- Cleaned up frontend forms and server request handling in the harbor-manager package to reflect the feature removal.
- Updated the downshift planning prompt instructions to maintain continuity in task creation.
- Modify downshift logic to ignore `todo` tool calls as triggers, requiring them instead to open a "gate" that permits switching only on subsequent `edit`/`write` actions.

- 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.

- Added `warning` field to `CompactionEntry` and `CompactionSummaryMessage` to persist dead-end status in session history.
- Introduced a multi-tier rescue mechanism in `AgentSession` that automatically performs `elide` and `dropImages` passes when maintenance fails to recover sufficient headroom.
