In-flight workspace UX work.
- Extract a shared PaneHeaderActions cluster (+/Split/Reopen/History/Close)
used by ChatTabBar + the Workspace coder/terminal pane headers, replacing the
divergent per-header copies; SessionLandingPage history + useWorkspacePanes
tweaks.
- Fix coder-side correctness bug: resolveChatId read sessions.workspace_panes as
a bare WorkspacePane[] but v2.6.5 widened it to a WorkspaceState envelope, so
it mis-read panes and clobbered tabNumbers/nextTabNumber/closedPaneStack on
every pane-chat write. New normalizeWorkspaceState handles either shape and
preserves the envelope (+ regression test).
- CLAUDE.md doc-sync (coder vitest suite, deploy-by-surface, dual-remote push,
in-flight-web-WIP staging, release-branch naming).
Web tsc + coder build + coder tests green. Builds on v2.7.6.
pending_changes.agent stamped at every queue site (native -> 'boocode', dispatched external -> task.agent, manual RightRail -> NULL) + flows through listPending. New GET /api/sessions/:id/agent-sessions -> [{agent,status,has_session,last_active_at}] per (chat,agent). opencode warm server consumes session.next.step.ended, accumulating input_tokens/output_tokens/cost onto agent_sessions (new idempotent columns) via a pure opencode-usage.ts mapper. Tests: agent-sessions.routes (3) + opencode-usage (6); tsc clean.
GET/PATCH /api/providers/config, subset POST /refresh, and
GET /api/providers/:id/diagnostic (JSON { diagnostic }, §6.4). PATCH order
is validate→save→reload→clear; a malformed body or invalid merged config
returns 422 without writing, and a save failure returns 500 without
reloading (no file/registry divergence). Web client + types extended.
