🔭 fix: Attach to Runs This Pane Did Not Start (#15074)
* 🔭 fix: Attach to Runs This Pane Did Not Start

A run started somewhere else — another tab, another device, a scheduled
trigger — announces itself to this client only through the user-scoped active
job list. Nothing consumed it for attachment: `useActiveJobs` feeds the
sidebar's generating indicators and a `hasActiveJob` hint inside the messages
query, and that is all.

That left the status query as the only path to an attachment, and it closes
for the rest of a conversation's mount the moment it has answered inactive
once, because `processedConvoRef` is set on that answer. So a pane already
sitting on a conversation when a run begins elsewhere never attaches, never
refetches (the messages query disables refetch on focus, mount and reconnect),
and shows history it cannot see has moved on — until a reload or a navigation
remounts the query. Worse than the stale render: a send from that pane derives
its parent from the stale tail and forks a sibling branch. The two send-time
staleness guards in `useChatFunctions` do not fire, because nothing invalidated
this pane's cache, so it looks fresh.

Re-arm the status query when the viewed conversation appears in the active
list. The announcement is consumed once per run rather than held open — a job
stays listed for its whole lifetime, and re-opening on every poll would turn a
five-second heartbeat into a five-second status read — and released when the
run leaves the list so the next one re-arms in turn.

* 🩺 fix: Make the External-Run Re-Arm Survive Warm Caches and Back-to-Back Runs

Five gaps between the announcement and the attachment it was supposed to
produce, none of which the happy-path test could see.

The announcement could never arrive. `useActiveJobs` disables its interval
while nothing is listed and `refetchOnWindowFocus: true` refetches only stale
queries, so a run another client started inside the five-second `staleTime`
window was invisible on return to the tab — the exact sequence this is for.
Focus refetches unconditionally now.

Re-arming could consume a stale answer. Toggling `enabled` only fetches when
the cached data is stale, and `useStreamStatus` holds `staleTime: 1000`, so an
inactive status answered moments earlier was replayed as "nothing running" and
recorded as handled. The re-arm invalidates the status query rather than
trusting the toggle.

Attaching could graft onto a hole. An external client may have completed whole
turns this pane never saw before starting the one now running; the resume
submission and `finalHandler` both build on the local snapshot. And when the
announced run turned out to be already terminal, nothing refreshed history at
all — the messages query disables refetch on focus, mount and reconnect, so
those turns simply stayed missing and a send from here still forked. The
re-arm invalidates history too, which also re-gates `messagesLoaded` so the
check waits for it.

Consecutive runs could be missed. A latch released by observing the list empty
never releases when a second run starts before the next poll, since the list
reads the same throughout. Rate-limit to the list's own heartbeat instead,
keyed on `dataUpdatedAt` — structural sharing keeps the payload reference
stable across identical refetches, so only the fetch stamp moves.

Wiring, found by these tests rather than by review: clearing a ref neither
schedules a render nor re-runs an effect, so the arm is a state value the
check depends on.

🚀 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 .potx templates 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.
