* 📐 docs: Record Who Owns Which Piece of Client State * 🔌 refactor: Give the Subagent Surface a Host Seam and Its Own Jotai State The subagent chat surface reached up into seven application atoms and could not be lifted anywhere, and the six atoms it owns were still Recoil while its sibling stores had already moved to Jotai. Feature-owned state converts to Jotai and stays where it is: the selection, per-task control receipts, live progress and the parent-stream fence. The control atom keeps its session-storage retry — restored per store rather than per family member, so a reload still sees what the last one persisted. App-global state now arrives through one `ChatSurface` value the host supplies: `enterToSend`, `maximizeChatSpace`, `showScrollButton`, the reader's composer bindings, a `claimForeground` command for the slot the panel and the artifacts panel share, and `handOffComposerText` for a continuation's unsent words. Two hosts mount the same adapter — the conversation view and the shared-link view. Opening the panel was three copies of "clear the artifacts slot, then select"; that is now `useOpenSubagentPanel`, and the three call sites say what they mean. Nothing under `Chat/Subagents/**` imports `~/store` or `recoil` any more, and its whole suite runs with no `RecoilRoot` at all. * 🧹 refactor: Move Subagent State Into the Feature and Free Its Drained Atoms Two review findings, both fair. The selection atom still lived in `~/store`, which handed the supposedly liftable surface an implicit dependency on the application store alongside its declared host interface — and contradicted the ownership rule this branch added to CLAUDE.md two commits ago. The module moves to `components/Chat/Subagents/state.ts`; the hosts that write it (the SSE step handler, the message renderers) now import from the feature, which is the direction that survives an extraction. The conversation-switch drain blanked its two atom-family members but left them cached. Every invocation key is unique, so a long-lived tab accumulated two atom configurations per subagent call it ever saw — exactly what the comment at that boundary says it exists to prevent. `removeSubagentProgressAtoms` releases them after the values are cleared, mirroring `removeUsageAtoms`. The new test fails without the release. * 🔎 fix: Let a Subagent Card Render Where There Is No Panel to Open Search results render the same card through `Part`, and that route is not beneath either chat surface — so a search hit containing a subagent tool call threw on `useChatSurface()` before it could render at all. Rendering the card and opening a panel are different requirements. The host stays required for the panel, the activity view and the event group, all of which only ever mount inside one. `useOpenSubagentPanel` reads the context optionally instead and answers `null` where there is no host, which is also the honest answer for search: there is no panel on that route to open, so the card renders with its details control disabled. The new test renders the card with no surface at all, and throws with the reported error when the hook is put back the way it was. * 🧮 fix: Enrol Read-Created Progress Atoms in the Drain Registry The read is what creates a family member, and only the streaming paths were registering their keys. A card rendering a conversation that finished streaming long ago — or a search result that never streams at all — created one the navigation drain could not see, so browsing history accumulated an atom configuration per card for the life of the tab. `useSubagentProgress` does both halves: it reads the invocation's progress and enrols its key, so every route into the family shares the one cleanup boundary. The panel and the parent card both read through it now. * 🧽 fix: Free a Read-Created Progress Atom at Its Own Card's Unmount Enrolling read-created keys in the drain registry only helps where something runs the drain, and `/search` is a standalone route that never mounts the chat event handlers. Scrolling a virtualised result list therefore kept minting members nothing would ever free. `useSubagentProgress` cleans up after itself instead: on unmount it frees the family members when the read is the only reason they exist. Two guards keep that from taking live history with it — a key the stream registered belongs to the drain, and a member holding folded activity is the record of what the child did, so reopening its card still shows it. * 🔗 fix: Free a Progress Atom Only After Its Last Reader Lets Go Opening a foreground panel before the first event gives one still-empty member two readers: the card that spawned the child and the panel showing it. Closing the panel freed it while the card was still subscribed — and a subscriber does not re-render just because its atom left the family, so the first SSE update landed on the replacement member and the card's ticker stayed dead. `useSubagentProgress` counts its mounted readers and frees only when the last one lets go, alongside the two claims that already blocked it: a key the stream registered, and a member holding folded activity. |

🚀 What's New in v0.8.8-rc1
- Agent run control: Interrupt or steer an Agent mid-run, queue follow-up messages, and reclaim, edit, or escalate pending steers.
- Human-in-the-loop Agents: Agents stream question progress, ask up to four related questions in one form, pause for input or tool approval, and resume.
- Unified Agent Builder: A redesigned Tools marketplace brings together Skills, MCP, Code Interpreter, orchestration, Programmatic Tool Calling, model-spec controls, and per-tool background and intent settings.
- Readable Agent activity: Generated activity-group headers, parent phase summaries, and live tool intent labels make long reasoning and tool runs easier to scan.
- Code Interpreter workflows: Code and shell tools can run in the background, sandbox images return as viewable artifacts, and highly experimental stateful sessions can reuse prewarmed conversation workspaces.
- Agent extensibility: Experimental Agent Plugins can bundle deployment Skills, MCP servers, and opt-in command hooks, while explicit subagents initialize only when selected.
- Memory, context, and identity: Agents can manage memory with optional per-agent isolation, expose support contacts safely, and show a more faithful Context Usage gauge.
- Sharing and files: Shared conversations show a badge and update at a stable URL, while signed-in viewers can continue them as personal copies.
- Artifact workflows: Open previews fullscreen, work with PowerPoint
.potxtemplates across upload, search, and code execution, upload shell scripts across common MIME variants, export Mermaid diagrams as SVG or PNG, and download original Office files from the artifact panel. - Models and reasoning: Added GPT-5.6 with Responses API reasoning controls, Claude Opus 5 and Sonnet 5, Gemini 3.7 and 3.6 Flash, and Gemini 3.5 Flash-Lite.
- Langfuse observability: Configure encrypted Langfuse connections in-app, let authorized admins open sampled sessions directly, optionally fan out traces by tenant, and suppress central export per run.
- Administration and security: Delegate config sections, encrypt registered secrets, enforce SSRF checks for speech, OCR, and web tools, and generate unique temporary credentials when secrets are blank.
- Messages and navigation: Right-aligned user turns, unified multi-part editing, full-message copy, a dock-style message rail, virtualized search, smooth streaming, and faster Agent startup.
- Streaming and tool reliability: Adaptive provider smoothing, Redis delta batching, dynamic MCP tool refresh, parsed MCP response media types, runtime OAuth recovery, and Agent stream circuit breakers improve long-running workflows.
- Deployment and reliability: Added configurable HTTP timeouts, Amazon DocumentDB 5.0+ support, low-noise Redis and browser observability, and a rolling-upgrade-safe generation protocol.
