docs: daily update 2026-08-07 — release v4.192.1

Release covered

v4.192.0...v4.192.1 (compare: v4.192.0...v4.192.1)

Note: the tagged release commit d2900ef is a [release]: bump squash, but the two-dot range v4.192.0..v4.192.1 (commits reachable from the new tag but not the old one) contains one real commit bundled into that same SHA:

• d2900ef57d42f375ae87640bafb8aa59748e1d7e — sandbox: renew a watched claim's TTL from open preview event streams, so a sandbox a user is actively viewing is never reaped by the idle housekeeper just because its agent is idle (apps/api/src/api/routes/sandbox-events-handler.ts, packages/sandbox/server/provider/agent-sandbox/runner.ts, packages/sandbox/server/provider/types.ts). Docs update warranted — this changes documented self-hosting behavior of the idle housekeeper / claim-activity refresh.

Everything else in the diff (Casks/deco-studio.rb, package.json versions, Helm chart/appVersion bumps) is release-version bumping only — no docs impact.

Depends on

This PR is stacked on top of #5838 (docs/auto-update-2026-08-07-release-4.192.0), which was still open when this run started. Merge #5838 first, then this one.

Files changed

• apps/docs/client/src/content/deco-studio/en/studio/self-hosting/deploy/kubernetes.mdx — clarified the "Idle housekeeper" section: claim activity is now refreshed by two sources (agent runs and any open preview stream), and an open preview's heartbeat renews the claim TTL every 5 minutes without ever shortening an existing shutdown commitment.
• apps/docs/client/src/content/deco-studio/pt-br/studio/self-hosting/deploy/kubernetes.mdx — matching translation.

Consistency notes

• Checked architecture.mdx, overview.mdx, concepts.mdx, agents.mdx, and decopilot/* for other references to sandbox idle/TTL/shutdown behavior — none describe housekeeper mechanics in enough detail to be contradicted by this change, so no further edits made.
• selfhost/production (outside apps/docs/) also documents housekeeper defaults but is out of scope for this automation (only apps/docs/ is in scope).

Translation

pt-br translated for the changed file; all other pt-br files are unaffected.

Summary by cubic

Updates docs for v4.192.1. Open preview streams now renew a sandbox claim’s TTL so any sandbox you’re actively viewing isn’t reaped by the idle housekeeper. Also adds Task Board docs and several self‑hosting clarifications.

• New Features

  • Idle housekeeper: preview-stream heartbeats refresh claim TTL every 5 minutes and never shorten a scheduled shutdown
  • Added Task Board guide (kanban tracking with comments and review)
  • Agent UX and providers: “Files & skills” with a 25MB per-file limit, blocks-form description tooltip option, and linking your own Claude Pro/Max plan for sandbox coding runs

• Self-hosting

  • Authentication is configured via AUTH_* env vars only (no auth-config.json)
  • Kubernetes: per‑org tenant warm pools to pre‑warm pods for specific repos
  • Docker Compose: STUDIO_TOPUP_FEE_PERCENT (supports 0 fee), task‑quota envs (STUDIO_TASK_QUOTA_ENFORCED, STUDIO_FREE_TASKS)
