side-conversation

0.2.0 — 2026

• Board → /goal sync (button-only, never automatic): the board objective (plus
  the next-steps list) creates or CAS-edits the session goal through the client
  goals.create / goals.edit face; the board itself stays a pure record by default.
• Bare /side opens an empty side conversation: no question is injected, the
  child reports a ready status (own turns detected past the seed boundary), and
  the user asks directly in the panel composer.
• Model + reasoning-effort picker in side details: the child's advisory
  session.models directory (provider groups + adapter effort options) drives
  session.selectModel, persisting per child and applying to its next step.
• Unseen side-status notifications: the session-header toggle shows a warning
  dot when a side conversation settles (completed / failed / cleanup-failed); the
  side-list poller diffs snapshots, opening the panel marks events seen, and the
  first snapshot of a session is a silent baseline.
• Pinned summary board（置顶摘要小黑板 / ChatGPT-style Notes）: CAS patch engine
  (src/board.ts), atomic JSON persistence (src/board-persistence.ts), optimistic
  client store with serialized transport, conflict parking + idempotent retries,
  lost-but-applied detection, /plugins/dsh-side/board routes, header toggle and
  the board UI pinned at the top of the right workspace.
• Sidebar collapse hotzone (best-effort): drag strip inside the left sidebar's
  right edge — full collapse to the rail below the host's 264px clamp and re-expand,
  delegated to the host's own toggleSidebar().
• Integrated right workspace (Side / Subagents / Goal) — grouped list + per-resource
  detail pages in the shell's right details column (squeeze, not overlay), session-fenced
  pollers, reference-counted subagent catalog, action admission gates, Escape ladder.
• 165 unit tests (domain / persistence / client store / registry / transcript / panel …).
