- Added a SessionFocusController to switch transcript and input context between main and subagent sessions.
- Added agent-hub Enter activation and double-left return behavior for focused local agents.
- Added view-session-based event and render logic to avoid stale focus-session state.
- Added status-line focused agent display with ghost icon and focused-mode border dimming.
- Recomputed `tools.discoveryMode: "auto"` in the deferred MCP closure in `sdk.ts` once the real tool count is known: a toolset crossing the threshold now flips discovery on, registers and activates `search_tool_bm25`, and skips `activateAll` instead of force-activating every MCP tool.
- Guarded the deferred MCP task against disposed sessions: added `AgentSession.isDisposed` and `enableMCPDiscovery()`, and the late connect now calls `disconnectAll()` instead of refreshing tools onto a dead session.
- Cleared `#fastPathKey`/`#fastPathItems` in `AssistantMessageComponent.invalidate()` so theme/symbol changes rebuild reused Markdown children instead of keeping stale captured themes.
- Memoized unusable read summaries as a `false` sentinel in `read.ts` so the per-session LRU no longer retains full sources of unsummarizable files.
- Broadened `HAS_REF_DEF` in `markdown.ts` to match backslash-escaped reference labels (`[a\]b]: x`) and cleared frozen stream-lex state on blank `setText()`.
- Added regression tests: deferred auto-discovery flip and mid-connect dispose (`sdk-mcp-auto-discovery.test.ts` + `many-tools-mcp.ts` fixture), fast-path child rebuild on invalidate, and escaped-ref-def incremental-lex equivalence.
Dynamically assigns segment colors by sweeping across the full HSV hue spectrum based on their track position. This ensures each segment has a distinct, predictable hue and removes the need for explicit `color` assignments.
- Added commit-stability signaling to transcript blocks and marked tool previews as unstable until expanded or finalized.
- Updated transcript scrollback promotion to derive live commit state only for blocks reporting commit-stable rows.
- Added tests ensuring provisional pending edit previews are never committed while durable live rows still promote after the stability window.
- Replaced global search query mutation logic with a dedicated `Input` instance so typing now supports cursor movement, word deletion, and other editor hotkeys.
- Updated search banner rendering to display the embedded input line with live cursor while preserving match-count formatting and prompt width handling.
- Extended `Input` with a configurable prompt and end-of-value cursor placement, then updated memory-search tests for the new hotkey-driven editor behavior.
- Added fuzzy search preprocessing to normalize case, camelCase, and punctuation.
- Added token and phrase scoring for exact, prefix, substring, acronym, and compact hits.
- Added fuzzyRank to return {item, score}-ranked matches and delegated fuzzyFilter to it.
- Updated settings search tabs to sort by best score, keep original-order ties, and mute unmatched tabs.
- Detached async task progress rows stopped running a redraw driver and task progress rendering switched running/pending rows to static task-icon text.
- Background task snapshots were frozen once blocks left the transcript live region, preventing later partial snapshots from repainting commit-eligible rows.
- Updated task-progress and detached-background-task tests to validate static task rows and the new freeze behavior.
- Ensured flattened chain rows under a `└─` branch are anchored by a vertical line one level right of the suppressed gutter (below the branch head's content), never in the `└─` corner column itself, resolving visual issues #2298 and #2325.
Fixes#2325.
- Updated `settings-selector-memory-refresh.test.ts` to assert the cross-tab search banner's cursor rendering (`b▌`) instead of the old `Search: b` label when verifying Escape clears the search before closing the selector.
Also normalizes setting labels/descriptions and carries the package changelog entries for this batch (adjacent unreleased bullets are not splittable per commit), restoring section placement disturbed by the two prior changelog hunks.
- Caught and logged npm `PluginManager.list()` rejections in `PluginSettingsComponent`, returning an empty plugin list so the settings tab no longer stays blank when plugin listing fails.
- Added tests covering Escape handling while lists are loading and marketplace rendering when npm listing rejects.
Removed the dead settings selector submenu guard so Escape reaches the active settings or plugins child component. Added a regression test for closing an open settings submenu before the parent selector.
Fixes#2331
- Added transcript and assistant block version tracking for finalized segments.
- Changed committed block reuse logic to require prior finalization and same version.
- Fixed rerendering of committed finalized blocks when version values changed.
Only chain rows should force their nearest connector gutter back to vertical.
Inherited gutters from older last-sibling ancestors must stay suppressed so
linear continuations under nested branched grandchildren do not draw floating
vertical lines below unrelated branch connectors.
Updated the TUI renderer, mirrored the HTML export renderer, regenerated the
HTML template, and extended the #2298 regression to cover nested branched
grandchildren with linear continuations.
Fixes#2298
The /tree selector and HTML session export rendered chain rows (flattened
user/assistant turns) with bare spaces when their nearest branched ancestor
was the last sibling, breaking the visual connection back to the branch
parent.
Cause: tree-selector.ts and export/html/template.js propagated
`show: !isLast` to descendant gutters, so any chain row under a `└─`
ancestor rendered the gutter as space instead of `│`. Branched
grandchildren correctly need that space to keep standard tree drawing, but
chain-flattened conversation rows lost their anchor.
Fix: at render time, when the row has no connector of its own (chain row),
force the gutter to `│` regardless of the ancestor's `show` flag. Rows
with their own connector still respect the `show` flag so a `│` never
floats below an unrelated `└─` for branched descendants.
Applied identically in tree-selector.ts (TUI) and export/html/template.js
(HTML export, regenerated into template.generated.ts).
Fixes#2298
The session-observer overlay is gone. The Agent Hub (ctrl+s, alt+a, or double-tap left arrow on an empty editor) presents one overlay with two views: a live registry table (status, unread irc count, current task, last activity; j/k to navigate, r to revive, x to abort/release) and per-agent chat (transcript + input line) — submitting revives a parked agent and steers it via the normal prompt path. Main is the ambient chat and stays out of the table.\n\nrenderInitialMessages no longer takes a prebuilt context: every redraw now reaches for AgentSession.buildTranscriptSessionContext() (full-history transcript with each compaction emitted inline at the point it fired, snapcompact frames re-attached on rebuild). UiHelpers drops the deferred-compaction render and the IRC autoreply branch that the new mailbox bus deprecated. CompactionSummaryMessage renders as a slim divider (── 📷 compacted · ctrl+o ──), expanding to the summary + snapcompact frame count. session-manager.buildSessionContext gains a { transcript: true } mode; an exported buildSessionContextFromFile() reads a session file without taking the writer lock so the hub chat view can tail any agent (parked or live). Theme picks up icon.camera + tool.irc symbol entries.
- Added type-to-search filtering across setting labels, IDs, values, and descriptions.
- Preserved selected item focus by ID when replacing settings during an active filter.
- Displayed search status, empty-filter hints, and no-match messaging while searching.
- Updated Escape handling to clear an active query before cancelling the list.
- Applied selection and navigation to filtered items to keep behavior consistent under search.
- Removed terminal risk mode toggles from config, terminal state collection, and render controllers.
- Dropped snapshot freezing, thaw tracking, and finalized-block replay in transcript rendering.
- Removed clear-on-shrink settings and initialization hooks from selector and interactive mode flows.
- Simplified render scheduling by using requestRender() without mutation flags or stream checkpoints.
- Defer MCP server discovery off the first-paint critical path for UI
sessions; tools and slash commands stream in through the existing
live-refresh channel once each server connects (non-UI modes keep the
blocking path). ~290ms off first paint with MCP servers configured.
- Build the model catalog's canonical-equivalence index lazily on first
read instead of eagerly in the ModelRegistry constructor. A default
interactive launch never reads it pre-paint, moving the ~210ms build
(over ~3,200 models) off the critical path: ~244ms (~16%) off cold boot.
- Memoize per-session read summaries (tree-sitter parse) on the content
hash of the freshly-read bytes; the file is still read fresh each call
so results stay correct. Repeat same-file summary read 17ms -> 2.4ms.
- Reuse the Markdown subtree across streaming reveal ticks, memoize
grapheme counting, and stop re-highlighting finalized thinking blocks.
- Attribute the previously-unlabeled synchronous boot region in the
PI_TIMING table and add a bench:guard boot-regression target.
- Dropped blank lines, capped at 8 lines, and width-truncated each line so a proxy 502's HTML body can't flood the transcript.
- Mirrored the pinned error banner's preview behavior; full text still kept in the persisted session.
- Derived descriptors, default-model map, env keys, login list, and refresh dispatch from one ProviderDefinition per provider.
- Disabled OpenAI Codex stream obfuscation and interrupted whitespace-only tool-call argument deltas.
- Derived auth-broker callback ports and paste-code login set from the registry.
- Added atomicTokenPattern support to treat image and paste markers as indivisible tokens, enabling atomic deletion on backspace and forward-delete instead of character-by-character removal.
- Extended image marker format to include pixel dimensions [Image #N, WxH] and updated paste marker format to [Paste #N, +X lines] or [Paste #N, Y chars] with consistent comma-separated metadata.
- Implemented accent styling for paste markers in editor rendering while preserving hyperlinks for image markers, improving visual distinction between marker types.
- Refactored image reference handling to unified placeholder system supporting both image and paste markers with kind-aware rendering callbacks and regex patterns.
- Added a LateDiagnosticsMessageComponent to render delayed LSP diagnostics as grouped tree nodes in transcript messages.
- Updated message handling to use that component and honor tool-output expansion while reusing shared diagnostics formatting.
- Added tests for shared rendering output, collapsed/expanded limits, and empty diagnostics behavior.
- Handled SGR mouse motion reports in `PlanReviewOverlay` to set hovered options from hit-test rows and clear highlights outside option rows.
- Updated option rendering to paint a background band on hovered, non-disabled options while preserving keyboard selection behavior.
- Enabled any-motion mouse tracking for overlays and expanded regression coverage to verify hover tracking setup and teardown.
- Added `isUserInterruptAbort` and `shouldRenderAbortReason` helpers so interrupt handling can distinguish Esc-based aborts from other abort reasons.
- Updated assistant transcript rendering to suppress the `Interrupted by user` line while continuing to show generic or other abort labels.
- Updated plan-review and transcript container tests to assert interrupted assistant messages no longer render the redundant interrupt line.
- Added `getCredentialOrigin` and `getEnvApiKeyName` to classify auth source.
- Surfaced provenance tags in the `/login` and `/logout` provider picker.
- Made the picker search filter match credential origin and env var name.
- Added coverage for credential-origin precedence and env naming.
- Added optional `reason` parameters to `Agent.abort` and `AgentSession.abort` APIs.
- Passed abort reasons through interrupt flows into underlying agent cancellation.
- Replaced hard-coded abort text with `resolveAbortLabel` for streaming and replayed messages.
- Fell back to generic `Request was aborted` text when no abort reason was provided.
- Added SGR mouse input handling for wheel and click actions, mapped to option, ToC, and body targets.
- Added deleted-heading state to undo snapshots so removed titles persist and restore correctly.
- Updated the plan-mode active prompt to require decision-complete, implementation-ready plans.
- Enabled mouse tracking for fullscreen overlays and asserted mouse-on/off sequences in tests.
- Added section-based plan parsing with per-section delete, undo, and annotate.
- Added Tab/Shift+Tab focus regions and per-line scroll navigation.
- Added Refine feedback loop emitting annotations back to the model.
- Added `OverlayOptions.fullscreen` borrowing the terminal's alt screen buffer.
- Added ChatBlock and ChatBlockHost with mount, finish, and dispose lifecycle callbacks.
- Added InteractiveModeContext.present and resetTranscript APIs and used them to mount/repaint blocks.
- Reworked controller rendering paths to emit command, event, extension, and selector outputs via ctx.present.
- Implemented component and container dispose hooks in tui so loaders and child blocks cleanup timers/effects.
- Centralized transcript spacing by stripping blank edges and inserting separators.
- Removed per-component leading spacers and empty placeholders that added extra gaps.
- Introduced TranscriptBlock grouping so related outputs render as single transcript children.
- Updated transcript-related tests to validate one-row block separators and blank-line trimming.
- Replaced the plan review flow to open PlanReviewOverlay for approvals.
- Added scrollable markdown plan rendering with prompt, options, and footer in the overlay UI.
- Added disabled-option handling so cursor movement and confirmation skip unavailable rows.
- Added setPlanContent updates to refresh overlay text and reset scroll position on edits.
- Shared immutable model registries and auth storage via beforeAll/afterAll.
- Swapped fixed-delay settle sleeps for predicate polling and signals.
- Stubbed network/timers to drop wall-clock waits in registry and history tests.
- Added resetDisplay invalidation tests and startup-timing breakdown lines.
- Added a fullscreen /copy tree of recent assistant messages with nested code blocks and a live preview pane.
- Removed the /copy last|code|all|cmd subcommands in favor of tree selection.
- Extracted copy-target assembly into a testable util.
- Wrapped selector and overlay list windows in ScrollView for proportional right-edge scrollbars.
- Dropped numeric position/count footers in favor of the scrollbar.
- Simplified SelectList status line to search hints only.
- Added ED3-risk autocomplete repaint test for POSIX terminals.
- Cleared native scrollback on `omp`/`omp -c` so the resumed transcript no longer stacks on the prior run's welcome screen.
- Tracked assistant block finalization so aborted streaming messages stay repaintable when status rows land beneath them on ED3-risk terminals.
