- Removed `#compactedChildStart` state, `compactable` segment field, and `#compactCommittedPrefix()` method, stopping the local-frame pruning of committed finalized rows.
- Post-finalize mutations now surface on every render via version tracking, instead of requiring a destructive replay to rehydrate the compacted block.
- Changed `print-mode.ts` to use `session.getLastAssistantMessage()` instead of array tail read, fixing access to terminal assistant messages after compaction removal.
- Kept tall-preview pages inside the selected option row.\n- Compared cached overflow output against the initial width-adjusted render.\n\nNote: pre-existing repository formatting failures in bun check are not addressed by this PR.
Ask dialogs accepted the configured cancel binding but always advertised Escape. Derive the compact footer label from the active binding so the displayed key remains actionable.
Rich ask options previously exposed preview content only for the highlighted row. Render every preview beneath its option and keep long content reachable without reviving the split-pane layout.
TranscriptContainer gated committed-prefix compaction on version === undefined, so version-tracked AssistantMessageComponent history never compacted and every stream tick re-walked all N sealed blocks (depth-linear compose).
Compact fully-committed finalized blocks regardless of post-finalize version tracking: their rows are immutable native scrollback the terminal owns. A post-commit mutation no longer recommits on ordinary frames (no duplication) and rehydrates on the next destructive full replay (no loss). Adds the permanent bench/transcript-compose.bench.ts fixture; ratio(N5000/N500) drops 2.30 -> 0.90.
Fixes#5930
Instead of including the xd:// device inventory in the system-prompt signature, mount/unmount events now inject a steered `xdev-mount-notice` message so the system prompt (and its provider cache prefix) stays byte-stable across MCP connects and disconnects. Full device docs are picked up opportunistically on the next unrelated rebuild.
Also caps external (dynamic-mount) device descriptions to 200 chars in `docsAll` to prevent server-controlled prose from consuming prompt budget; built-ins keep their full curated docs, and `read xd://` always returns the untruncated text.
Legacy `discoveryMode: "off"` → `tools.xdev: false` migration is removed; the setting keeps its own default without inference from the deprecated key.
- Added the `xd://` virtual device protocol (`internal-urls/xd-protocol.ts`, `tools/xdev.ts`): tools declaring `loadMode: "discoverable"` are unmounted from the request tools array and driven via `read xd://` (list/docs+schema) and `write xd://<tool>` (execute), gated by the `tools.xdev` setting (default on) and inlined into the system prompt.
- Merged the `irc`, `job`, and `launch` tools into a single `hub` tool (`tools/hub/`, `async/job-manager.ts`): messaging keeps `send`/`inbox`/`list`, job control maps to `wait`/`cancel`/`jobs`, process supervision keeps `start`/`logs`/`stop`/`restart`/`describe` with `ps`, and the unified `wait` races background jobs against peer messages; SDK `IrcTool`/`JobTool`/`LaunchTool` are replaced by `HubTool`.
- Removed the hidden `resolve` tool in favor of the `xd://resolve`/`xd://reject`/`xd://propose` resolution devices, auto-including `write` whenever a deferrable tool or plan mode is present.
- Removed the BM25 tool-discovery system: the `search_tool_bm25` tool, the `tool-discovery` module, the `tools.discoveryMode`/`mcp.discoveryMode`/`mcp.discoveryDefaultServers`/`tools.essentialOverride` settings, per-tool MCP selection, and the `mcp_tool_selection` message type.
- Unified tool presentation on `ToolLoadMode` (`essential`|`discoverable`), replacing the custom-tool `xdev?: boolean` opt-out; custom, extension, MCP, RPC host, image-generation, and TTS tools now default to `discoverable`, and added a `satisfies` predicate to `SoftToolRequirement`.
- Removed the standalone `ssh` command tool and `ssh/ssh-executor` (the `ssh://` read/write/search protocol stays), and made `--tools` address hidden built-ins.
- Updated collab-web to render `xd://` dispatches and `hub` op families, dropped the `search_tool_bm25`/`ssh`/`report-finding` renderers, refreshed tool docs and prompts, and migrated the affected tests and changelogs.
The /omfg generated-rule path validated conditions with raw new RegExp in normalizeConditionRegex and isValidRegexCondition, so a generated rule with a leading (?i)/(?m)/(?s) inline flag was rejected as "Invalid condition regex" before reaching TtsrManager.addRule. Route all three validation sites through compileRuleCondition.
Fixes#4796
The /todo rm reminder was a generic "user manually modified" message
showing an empty list, so the model read the cleared list as missing and
re-populated it on the next turn. buildSystemReminder now emits an explicit
do-not-recreate / do-not-re-add directive for removals while keeping
status mutations (done/drop) neutral.
Fixes#5258
- 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
- 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 comprehensive tests for downshifting model behavior, including plan nudge injection and completion safety mechanisms.
- Verified session persistence accuracy by validating that from-disk rebuilds match the live agent state.
- Confirmed correct cache key propagation during tan commands to ensure provider caching is preserved.
- Removed obsolete reasoning slide tests.
- 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.
- 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.
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.
- pickWeightedTip now takes the tip list and a uniform sample, exported for tests.
- Weighted-selection test sweeps a synthetic tip list, so shipping zero [NEW] tips no longer fails the suite.
- Enabled granular task execution by allowing batches to interleave blocking items with non-blocking async background spawns.
- Updated task orchestration to support simultaneous inline result collection and persistent background job tracking.
- Improved agent visibility in the job tool by reporting running subagents even when not explicitly linked to a backing job ID.
- Enhanced terminal state handling to prevent premature tool block closures while async background operations remain active.
- Replaced the legacy model selector with a full-screen Model Hub, introducing mouse support and a fuzzy-searchable browser.
- Integrated comprehensive model management, including role assignment, thinking-level visualization, and manual provider discovery.
- Implemented a cancellable OAuth login flow and integrated it directly into the Model Hub for provider authentication.
- Centralized model logic and migrated existing tests to support the new component architecture.
