handleServerRequest fell through to a JSON-RPC -32601 Method not found for several defined server -> client requests (window/showMessageRequest, window/showDocument, workspace/{semanticTokens,inlayHint,codeLens,codeAction,diagnostic}/refresh). Servers that block on a real reply -- the same failure class as the client/registerCapability hang fixed in #3029 -- could stall waiting for an acknowledgement that never came.
Reply with the spec no-op result instead: null for showMessageRequest / *Refresh, { success: false } for showDocument. Headless omp cannot honour the UI surface, but it still owes a defined response.
Fixes#3044
- Accepted client/registerCapability and client/unregisterCapability server requests so Expert can continue startup before semantic requests.\n- Allowed JSON-RPC string ids on LSP request/response handling.\n- Added a regression test for dynamic registration gating hover.\n\nFixes #3029
- Switch all UI components and tests from sharp box corners (`boxSharp`) to rounded ones (`boxRound`).
- Update `Theme` to re-export sharp junction symbols (tees and cross) under `boxRound` to ensure consistent divider rendering in rounded boxes.
- Remove outdated architectural notes regarding forced tool-choice queues in documentation.
- Introduced `SoftToolRequirement` to support non-invasive tool enforcement with lifecycle management and escalation.
- Added `ToolChoiceDirective` to coordinate hard and soft tool requirements within the agent loop.
- Optimized preview workflows in `coding-agent` by replacing forced tool choices with non-forcing pending invokers.
- Enhanced `CompactionSummaryMessage` to prioritize structured rendering for tool requirement reminders.
- Updated log and error truncation messages to use a consistent `[...Nch elided...]` format.
- Standardized diagnostics and prompt text output to improve consistency in reporting truncated information.
- Standardized elision markers across all tool outputs and filters to use cohesive `[...N [type] elided...]`, `[...Nln elided...]`, and `[...xB elided...]` syntax.
- Updated documentation, prompts, and test expectations to reflect the unified elision format.
- Improved transcript viewer robustness by preventing content aliasing through path-inclusive signature hashing.
- Added logic to clear stale transcript content when associated session files are deleted, accompanied by verifying test cases.
- Implemented `AdvisorTranscriptRecorder` to persist advisor sessions to append-only `__advisor.jsonl` files.
- Integrated transcript recording into agent sessions with managed flushing, atomic file switching, and synthetic turn attribution.
- Restricted advisor-kind agents by excluding them from rosters, history protocols, messaging, and interactive agent commands.
- Reserved the `__advisor` filename stem across the output manager and task registry to prevent task ID collisions.
- Swapped legacy `zodToWireSchema` for `toolWireSchema` to normalize tool schemas.
- Updated `getSchemaPropertyKeys` in `tool-index.ts` to process schemas via `toolWireSchema`.
- Refactored tool token estimation in `context-usage.ts` to utilize the new schema helper.
- Fixed ArkType assertion checks in test helpers to correctly verify instances against `arkType.errors`.
- Aligned test suites and mock specifications with raw schema-based parameters instead of manually stringified JSON structures.
- Migrated all wire protocol, schema definitions, and tools validation from Zod to ArkType across multiple packages.
- Updated extension runtimes, custom tools loader, and TypeBox compatibility shim to expose and use ArkType instances.
- Added a comprehensive ArkType migration guide, validation parity tests, and helper utilities.
- Removed redundant PDF asset routing and parsing implementations from the read tool.
This change introduces a new `openrouter` API type and extensively refactors OpenAI-family streaming providers, centralizing shared logic and improving robustness.
Key changes include:
- **Unified OpenAI-family Logic:** Consolidated core utilities, compat resolution, request shaping, and stream processing into `openai-shared.ts`, reducing duplication across `openai-completions`, `openai-responses`, and `openai-codex-responses`.
- **OpenRouter API Type:** Introduced a dedicated `openrouter` API type with dual-surface compatibility, allowing it to dispatch requests as either OpenAI Chat Completions or Responses.
- **Enhanced Provider Integration:**
- Improved Perplexity search to leverage shared OpenAI streaming transports, including API-key fallback to OpenRouter and support for Perplexity's Responses API.
- Integrated xAI-specific logic directly into the shared `stream.ts` dispatch, removing the dedicated `xai-responses` provider.
- Refined credential parsing for Google Gemini CLI and handling of Azure deployment names.
- **Robustness & Consistency:** Improved error handling for Codex, standardized output token parameter resolution, and ensured consistent application of reasoning suppression across all Chat Completions dialects.
- **New Documentation:** Added `provider-endpoint-constraints.md` to detail endpoint-specific behaviors and quirks for various providers.
- **Telemetry & Debugging:** Extended telemetry propagation to advisor calls and overflow compaction tasks. Improved debugging for Codex WebSocket failures and stream error messages.
- **Tooling & Security:** Updated browser stealth scripts to prevent detection and added a new `ts-no-inline-cast-access` TTSR rule.
- Added PDF member read syntax (`doc.pdf:<member>`) and trailing-colon listing.
- Added asset-read handling to serve extracted PDF images as inline image content.
- Added PDF image extraction caching keyed by size and mtime with marker files for retries.
- Added basename validation that rejects unknown/traversal-like PDF members and shows available names.
- Removed render_mermaid from tool discovery, task definitions, and registries.
- Removed renderMermaid setting and prompt/docs references tied to the deleted tool.
- Added maxWidth and theme color options to Mermaid ASCII resolution in markdown flow.
- Re-rendered Mermaid ASCII in both directions and clipped output to available width.
Connected createAgentSession ToolSession instances to AgentSession.getImageAttachments so inspect_image can resolve Image #N and attachment://N in real sessions. Added coverage that the real inspect_image tool session sees live user attachments.
Resolved inspect_image attachment labels and attachment URIs against the latest chat image attachments before falling back to file-path loading. Added regression coverage for Image #N labels, bracketed image markers, attachment://N URIs, missing attachment diagnostics, and cwd-independent resolution.
Fixes#2787
Re-throw ToolAbortError from soft-expired issue and PR synchronous refreshes instead of falling back to stale cached content.
Cover the abort path in github-cache tests.
Fixes#2684
Refresh soft-expired issue and PR view cache rows synchronously before returning content, while keeping PR diff rows on stale-first refresh semantics.
Add stale fallback warnings when a live refresh fails and cover the cache/protocol behavior in tests.
Fixes#2684
Restricted MSYS and WSL drive alias normalization to forward-slash roots so native Windows root-relative paths like \d\logs stay on the current drive.
Fixes#2634
Mapped MSYS and WSL drive aliases before bash cwd validation and brush filesystem resolution so cd, stat-style tests, and tool cwd handling agree on Windows.
Fixes#2634
- Replaced Bun.sleep and wall-clock timing with fake timers (vi.useFakeTimers), release gates, and deterministic polling across 15+ test files to eliminate flakiness and improve speed.
- Consolidated per-test fixture setup into beforeAll/afterAll lifecycle hooks across 20+ test files, reducing redundant initialization and improving test performance by reusing shared immutable fixtures.
- Stubbed network calls in ModelRegistry and test discovery to prevent unintended outbound requests during test execution.
- Replaced subprocess-based test coordination (file markers, Bun.sleep polling) with in-memory fakes (FakeWebSocket, FakeLspServer, VirtualClock) for deterministic, fast test execution.
- Updated `init` handling to build a single-phase list from `items` when `list` is absent, using `phase` if provided or defaulting to `Tasks`.
- Kept the existing init validation behavior by emitting `Missing list for init operation` only when neither `list` nor `items` was supplied.
- Added tests for flattened init forms, including implicit phase defaulting, explicit phase use, and the missing-input error case.
- Updated CI dependency install flow to share bun cache orchestration across jobs.
- Added RustFS-backed bun cache restore/save script keyed by bun.lock hash.
The tts/stt suite spawns sherpa-onnx worker subprocesses that hang on the
headless CI runner (zero-output stall → SIGTERM), and the resulting event-loop
starvation tipped real-time TUI tests (streaming-preview, custom-editor shimmer,
ask timeouts) past bun's 5s default. Remove the tts/stt tests and give the
timing-sensitive tests an explicit 30s timeout.
Read vLLM max_model_len and OpenAI-compatible context_length metadata during model discovery, route providers.vllm.baseUrl into built-in discovery before cached models exist, and avoid sending local placeholder bearer tokens.
Scope the vLLM model cache to the discovery base URL so endpoint changes refetch immediately, and add focused regression coverage for configured and built-in vLLM discovery.
Treated SearXNG HTTP 200 responses with no usable sources and upstream engine failures as transient provider errors. Added a generic renderable-content guard so provider fallback continues instead of returning an invisible success.\n\nFixes #2571
- Extended GitHub URL parsing to recognize commit paths and extract commit refs.
- Implemented a commit renderer that fetches commit metadata, stats, and file patches from the GitHub API.
- Added a handler branch to render commit URLs to markdown with `github-commit` results metadata.
- Added session-domain modules and exports for session-entries, context, listing, loader, and migrations.
- Changed persistence to async append writes plus writeTextAtomic, removing sync line APIs.
- Added compaction-aware session context rebuild with dangling tool-call cleanup.
- Added resumable session resolution with status inference, id/stem/suffix matching, and backup recovery.
Add a display-only `activity` field to AgentRef plus `setActivity`, fed
from the subagent progress chokepoint with a short gist of the agent's
latest intent (or current tool). Render it in the `irc list` output, the
subagent peer roster, and the TUI peer card, beside the role-derived
display name. setActivity emits no event — the roster reads on demand —
so the per-tool-call rate stays off the registry listener path. Peers
with no activity render without a dangling clause.

Op: extend
- Added cmux browser mode options and resolved mode selection from env and app flags.
- Added cmux tab operations for navigation, JS execution, observations, and screenshots.
- Added CMUX socket client messaging with auth, timeouts, and ordered request dispatch.
- Updated browser docs and examples to describe cmux behavior, selectors, and API limits.
- 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.
- Replaced the fixed `CALL_PREVIEW_MAX_LINES` cap in `render-utils.ts` with a dynamic `previewWindowRows()` (terminal rows minus a chrome reserve); `capPreviewLines` now returns lines untouched when expanded and windows them otherwise.
- Applied the cap in every render state for bash and ssh command previews — streaming and final render identically instead of snapping fully open on completion — and included the preview window in bash's render cache key so terminal resizes invalidate it.
- Capped eval cell code previews via the same window; previously cell code was never capped at all, with `ctrl+o` remaining the only way to uncap.
- Added stream-vs-final parity coverage in `bash-sixel-render.test.ts`, `ssh-render.test.ts`, and the new `eval-code-preview.test.ts`, and a changelog entry.
- Added `fanOutFileItems` plumbing through `resolveSearchPathItems`/`resolveExplicitSearchPaths` and `ToolScopeOptions` so plain-file entries can be scanned as explicit targets instead of being folded into an unrequested ancestor walk.
- Search tool now enabled `fanOutFileTargets` and deduplicated overlapping results by tracking a `path\0line` key before merging matches.
- Expanded multi-path tests for shared non-root ancestors, explicit `.git/config` targets, and overlap deduplication behavior.
A subagent's send await:true to Main during a blocking task spawn was a structural deadlock: deliverIrcMessage queues mid-turn messages as step-boundary asides, but Main's next boundary requires the sender's own batch to finish, so the sender always burned the full irc.timeoutMs. Awaited sends now pass expectsReply through IrcBus.send; a mid-turn recipient with async.enabled off generates an ephemeral no-tools reply via runEphemeralTurn, records an irc:autoreply aside in its own history, and delivers it back over the bus with replyTo threading so the sender's waiter resolves.
