RPC mode iterated readJsonl(Bun.stdin.stream()), where JSON parsing runs
inside the generator. A parse error thrown from the generator escaped the
frame loop's try/catch (which only wrapped dispatch), unwound runRpcMode,
and exited the process on any non-JSON stdin line.
Read raw lines via readLines and JSON.parse each inside the existing
try/catch so a malformed line emits a Failed to parse command error frame
and the loop keeps running. Shared readJsonl stays strict for session-file
reads.
Fixes#5194
Plugin/custom tool renderers can return a component whose render() throws
(e.g. a plugin styling its header off an object without a bold method,
producing TypeError: th.bold is not a function). ToolExecutionComponent only
caught the renderCall/renderResult factory, not the child component's later
render() pass, so the exception escaped and crashed the transcript.
Wrap every renderer-returned call/result component in SafeToolRendererComponent,
which catches render() errors and falls back to the tool label (call) or raw
result text (result), logging once per component.
Fixes#4978
Registered ACP session disposal with postmortem and replaced the hard EOF exit with the awaited graceful shutdown path.
Classified stdio-write EPIPE separately from worker IPC EPIPE so ACP peer loss exits successfully after cleanup.
Fixes#4788
- Normalized completed image_generation_call results into assistant image blocks.
- Persisted image bytes through the session blob store and rendered them in live, replay, ACP, proxy, telemetry, and HTML paths.
- Added response normalization, persistence, and TUI rendering regressions.
Fixes#4768
Plugins subclass CustomEditor/Editor and forward the upstream-pi
super(tui, theme, keybindings) constructor, which is the arg order
setEditorComponent's factory contract advertises. omp's base
constructor is constructor(theme), so the TUI landed in the theme
slot and every render threw
"undefined is not an object (evaluating 'this.#theme.symbols.boxRound')".
CustomEditor now resolves the real EditorTheme by shape rather than
position and captures a leading TUI so plugin overrides calling
this.tui.requestRender() keep working.
Fixes#4766
- 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.
Global settings proxy throws "Settings not initialized" when accessed
without Settings.init(), which breaks interactive-mode-status tests
under certain test ordering. Use this.ctx.settings like all other
access points in the method.
- 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.

- Updated the server to default to apple-container when the container CLI is detected.
- Removed unused auto_compaction_end event handling in the coding-agent print mode.
- Sanitized CLI JSON output by stripping sensitive payload data and implementing incremental delta extraction.
- Optimized log parsing in the harbor-manager by using tail-scanning and streaming file handles to prevent OOM errors.
- Enhanced process management to support persistent runs across manager restarts and improved orphan process handling.
- Added incremental cost probing for live trials and verified status transitions for runner lifecycle events.
- Removed the `downshift.boomerang` feature, including CLI flags, configuration schema settings, and internal session state logic.
- Deleted the associated prompt definition file and all unit tests related to the boomerang validation flow.
- 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.
- Introduced `--downshift-boomerang` CLI flag and `downshift.boomerang` configuration setting.
- Integrated boomerang validation hand-back logic and context cutting within the agent session.
- 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.
- Clear inherited todo list state and persist empty edit at fork creation to prevent parent task reminders from affecting the tangential session.
- Re-inject the fork notice after each auto-compaction event to ensure the boundary between the parent and child session survives history summarization.
- Align the provider cache key with the parent's actual pinned key to correctly mirror cached session context.
- Update `AgentSession` to perform a full entry rewrite during tool result pruning to ensure session files match pruned state for reliable resuming and branching.
- Implemented a consolidated TUI renderer for launch tool operations to unify status headers and metadata.
- Added tracking for unfulfilled readiness conditions to distinguish between timeout causes and daemon states.
- Enhanced timeout reporting to explicitly surface specific unmet log or port conditions.
- Included comprehensive unit and regression tests for tool rendering and start-timeout diagnostics.
- Added a system prompt to define boundaries for tangential agent forks.
- Injected the context-switch notice into new clones to prevent task leakage from parent sessions.
- Added support for role switching via `@` search prefix in the model picker.
- Implemented `quickRoles` configuration and logic to handle role-specific selections via the session API.
- Updated the model browser to support preserving query order and custom label coloring for improved navigation.
- Integrated role cycle tracking and updated UI hints to support the new role-browsing workflow.
- Redesigned agent hub entries as two-line cards, separating identity and status from task descriptions.
- Added explicit model and thinking level badges to agent status information.
- Updated agent hub rendering to support multi-line entries and adaptive vertical scrolling based on row height.
- Simplified status display by using glyphs instead of redundant status labels.
- Adjusted rendering logic to prioritize displaying agent task summaries on an independent indented line.
- Added `StrippedToolCallsMarker` to identify assistant messages with dangling tool calls that were removed during context building.
- Updated `buildSessionContext` to preserve turn entries in transcripts even when all content is stripped, marking them with the count of elided calls.
- Updated `UiHelpers` to render a dim, italicized placeholder in the TUI when an assistant message has elided tool calls, preventing silent activity gaps.
- 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.
- Integrated visual indicators for dead-ends into the `CompactionSummaryMessageComponent`, surfacing warnings directly on the compaction divider and detail block.
- Updated `AgentSession` logic to re-evaluate progress after each rescue tier and emit recovery notices, ensuring transparent reporting of automated history rewrites.
- Replaced markdown-style headings with concise `¶user:`, `¶think:`, `¶ai:`, and `¶call:` scope markers.
- Updated the serializer to merge consecutive messages or blocks of the same type under a shared prefix.
- Updated the documentation prompt to reflect the new compact formatting and scope rules.
- Added regression tests verifying scope merging and correct formatting of tool calls and intents.
- Updated transcript session context to use display.collapseCompacted setting instead of a hardcoded boolean.
- Enabled user-defined control over whether compacted history is collapsed during live rendering sessions.
- Introduced conditional scrollback clearing during UI renders when transcript compaction is enabled.
- Updated `CommandController` and `EventController` to respect the `display.collapseCompacted` setting.
- Configured `SelectorController` to trigger a chat rebuild and UI reset when the compaction setting changes.
- Updated `InteractiveMode` to dynamically toggle between collapsed and full inline history based on user settings.
- Initialized session metadata including system prompt, task, and toolset within the controller.
- Added session initialization tracking to the clone creation flow to ensure session state visibility.
- Updated unit tests to verify that session initialization data is correctly appended when a tan is created.
- Stop propagating real-time updates for backgrounded Bash jobs to avoid UI flickering once a job enters the background.
- Refine background task tracking in `EventController` to distinguish between persistent background tasks and transient backgrounded Bash commands.
- Update UI rendering to display cleaner background job metadata in the footer instead of inline text notices.
- Introduced ModelPickerComponent to enable temporary, floating model selection overlays.
- Centralized role management logic using a new resolveRoleAssignments function in the browser.
- Streamlined model hub by removing legacy pick-mode logic and defaulting to fullscreen views.
- Synchronized model picker state with the registry to ensure accurate offline refreshes.
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.
Applied explicit thinking suffixes from matching configured model roles when the temporary model picker switches the session model.
Added regression coverage for the Alt+P temporary picker resolution path.
