Commits reviewed

• ✅ Warranted a docs change: 139ce7a — feat(task-board): task comments, persisted (feat(task-board): task comments, persisted #5688). Adds a persisted comment feature to Task Board cards: one level of replies, resolve/unresolve on the thread root, scoped per organization. (Note: the shipped version dropped @-mentions and the subscribe toggle from the original UI-only draft, since neither had a backend to make them meaningful — docs reflect only what shipped.)
• ⏭️ Skipped: 6df58ce — [chore]: bump homebrew cask to 4.171.1 — release automation, no user-facing change.
• ⏭️ Skipped: 7f9e053 — [release]: bump changed workspace versions — version bump only.

Commits reviewed: 3 (1 warranted a doc change, 2 skipped)

Files changed

• en/studio/task-board.mdx — added a "Comments" section documenting threaded, persisted comments (one level of replies, resolve/unresolve).
• pt-br/studio/task-board.mdx — translated the same section.

Consistency notes

• concepts.mdx and architecture.mdx reference Task Board only in passing (a cross-link and an unrelated sandbox note) — no changes needed there.
• No built-in-tools.mdx file exists in this repo's docs tree, so the new TASK_BOARD_COMMENT_* tools were not added to a tools reference page. Flagging in case such a page is added later.

Translation

pt-br content was auto-translated; product terms (agent, task, comment, thread) and UI labels kept in English where the UI itself is in English.

Labels: documentation

Summary by cubic

Daily docs update for v4.172.0. Adds Task Board docs with threaded, persisted comments and automated reviewers, and updates architecture, agents, connections, and self‑hosting guides.

• New Features

  • Task Board: new page; threaded comments with one level of replies and resolve/unresolve; QA Agent and Code Reviewer with optional auto-merge; “Ship to production” when reviews pass.
  • Agents: “Files and skills” attachments with a 25MB cap and warning; repo picker shows forks and enforces GitHub App access.
  • Studio Native: choose a coding-agent terminal per brand-new thread (Claude Code, Codex, OpenCode); reclaim local worktree on archiving the last thread on a branch. CMS: optional tooltip layout for field descriptions. Decopilot: “Requires action” is set only by pending tool calls, not text heuristics.

• Self-hosting & Infra

  • Auth: configuration is AUTH_* env vars only; added docs for Google/GitHub login, email providers, magic link, and email OTP. Compose and Kubernetes guides updated.
  • Architecture: desktop tier removed from flow; documented hosted-run harnesses — default Decopilot and opt-in claude-code running inside the sandbox pod; clarified NATS live-tail role.
  • Kubernetes: added sandbox-daemon OTLP metrics opt-in and guidance on using a collector ClusterIP; sandbox is Go-only (ghcr.io/decocms/studio/studio-sandbox-go) with updated values.
  • Connections: block private/internal-network URLs at creation and health checks.
