docs: daily update 2026-07-31

[deco-cms]

Summary

Daily docs check for release v4.155.1 (range v4.155.0...v4.155.1).

Depends on: #5493 — this branch is stacked on docs/auto-update-2026-07-31-v2 (the most recently-created open docs PR at the time of this run) to avoid merge conflicts. Please merge #5493 first, then this PR.

Commits reviewed (v4.155.0...v4.155.1)

Warranted a docs change:

• b27fac05c — fix(settings): validate DUCKDB_THREADS instead of silently producing NaN (fix(settings): validate DUCKDB_THREADS instead of silently producing NaN #5505). DUCKDB_THREADS is a documented self-hosting env var; its startup validation behavior changed from "silently becomes NaN" to "fails fast with a clear error", which is worth documenting.

Skipped (reviewed, no docs impact):

• 80377b4ac — perf(task-board): batch activity-log inserts in TASK_BOARD_ITEM_UPDATE (perf(task-board): batch activity-log inserts in TASK_BOARD_ITEM_UPDATE #5507). Internal performance refactor; same activity-log entries are produced, just written in one batched insert instead of several sequential ones. No user-facing or API behavior change.
• 32ff201c6 — fix(daemon): stop BranchStatusMonitor watchers in branch-status tests (fix(daemon): stop BranchStatusMonitor watchers in branch-status tests #5504). Test-only fix.
• 14edc36, b723739, 77a199c — chore/release bump commits (homebrew cask bump, workspace version bumps). Not user-facing.

Files changed

• apps/docs/client/src/content/deco-studio/en/studio/self-hosting/monitoring.mdx — added a troubleshooting bullet and updated the DUCKDB_THREADS env var table row to document the new startup validation (positive-integer check, fails fast on abc/0/-1/1.5).
• apps/docs/client/src/content/deco-studio/pt-br/studio/self-hosting/monitoring.mdx — matching translation, auto-translated from the English change (code, URLs, and the DUCKDB_THREADS variable name kept in English).

Consistency notes

Searched all deco-studio docs for other references to DUCKDB_THREADS / DUCKDB_MEMORY_LIMIT / DuckDB env vars — studio/self-hosting/monitoring.mdx is the only file that documents them, so no other pages needed updates.

Summary by cubic

Daily docs refresh across English and Portuguese to cover new product behavior and self-hosting validation. Highlights include sections editor improvements, shared cloud sandbox, Mac desktop app install, AI Gateway top-up cap, Decopilot subagent concurrency, seat billing, and DUCKDB_THREADS validation.

• New Features

  • Sections editor: reorder and preview variants; map picker for Location matchers (requires a Google Maps API key).
  • Agents: cloud sandbox shared per branch; local runtime via deco link stays isolated.
  • Desktop app (Mac): install via curl or “Install on Mac”; Apple Silicon only for now.
  • Billing & providers: seat management for invoiced orgs with staged apply; AI Gateway top-ups capped at $10,000 per request.
  • Decopilot: DECOPILOT_MAX_CONCURRENT_SUBAGENTS limits concurrent subagents; invalid values fail at startup; extra calls queue.

• Bug Fixes

  • Self-hosting monitoring: DUCKDB_THREADS must be a positive integer; added a troubleshooting note and updated the env var table.
