e49ee381c — refactor(shared): remove dead Event Bus tool category (#5692)	Removes the empty "Event Bus" entry from the shared ToolCategory union/registry (dead code — the category was always populated with []). Also allows STUDIO_TOPUP_FEE_PERCENT=0 to waive the AI Gateway top-up fee for self-hosted deployments (previously 0 threw a validation error).	Partial — see below
c5f3054	[release]: bump changed workspace versions	none (version bump only)

Skipped / no docs change:

• Event Bus tool-category removal — already accurately documented as a dormant feature in studio/architecture.mdx ("The event bus is dormant..."). Removing the empty UI grouping doesn't change that guidance; no edit needed.

Warranted change:

• STUDIO_TOPUP_FEE_PERCENT now accepts 0 to disable the top-up fee entirely, explicitly called out in the code comment as useful for self-hosted deployments. This env var wasn't previously documented anywhere, so added it to the self-hosting Docker Compose environment-variable reference (the only existing home for this kind of self-hosting env var doc).

Files changed

• studio/self-hosting/deploy/docker-compose.mdx (en) — added STUDIO_TOPUP_FEE_PERCENT row to the "Environment variables" table plus a short callout clarifying it only matters when Stripe billing is enabled.
• studio/self-hosting/deploy/docker-compose.mdx (pt-br) — mirrored translation.

pt-br was auto-translated (prose translated; code, URLs, component names, and product terms like "self-hosted", "MCP" kept as-is per convention).

Consistency notes

• Checked quickstart.mdx, concepts.mdx, overview.mdx, ai-providers.mdx, self-hosting/quickstart.mdx, and self-hosting/deploy/kubernetes.mdx for stale references to "Event Bus" or top-up/fee behavior — none reference STUDIO_TOPUP_FEE_PERCENT, STRIPE_SECRET_KEY, or STRIPE_ORG_PRICE_ID, so no other page needed changes. ai-providers.mdx's "top up" mention is about the hosted Deco AI Gateway credit flow, unrelated to the self-hosted fee-percent env var — no change needed there.
• No contradictions found elsewhere.

Dependency note

This branch is based on the HEAD of #5690 (docs/auto-update-2026-08-04-release-4.172.0), the most recently created open docs-auto-update PR at the time this ran. Please merge #5690 first, then this one, to avoid conflicts.

Summary by cubic

Docs refresh for v4.173.2 adding the Task Board guide, the hosted claude-code harness, and Studio Native coding-agent terminals, plus self‑hosting and safety updates. Also documents sandbox daemon telemetry, Go-only sandbox image, new UX options, and the STUDIO_TOPUP_FEE_PERCENT=0 fee waiver.

• New Features

  • Task Board: new page; threaded comments; QA/Code Reviewer and auto‑merge options.
  • Agents: documented hosted claude-code harness; Studio Native coding-agent terminals; branch worktree reclaim on archive.
  • UX: “Files and skills” with a 25MB per-file limit; blocks-form field descriptions can show as tooltips.
  • Connections: block private/internal-network URLs for health and safety.
  • Architecture: simplified to cloud-only overview; clarified NATS’ live role.

• Migration

  • Self-hosting auth is AUTH_* env-vars only (no auth-config.json); see Authentication for variables.
  • Docker Compose: added STUDIO_TOPUP_FEE_PERCENT (0–100); set 0 to waive top-up fees for self-hosted.
  • Kubernetes: optional sandbox-daemon OTLP metrics (requires collector ClusterIP); sandbox image is now ghcr.io/decocms/studio/studio-sandbox-go.
