Optional integration secrets are now vault-only in the server runtime. GitHub App, Slack, Daytona, Brave Search, and LLM provider secrets no longer fall back to process environment variables or server.env when Fabro is running as a server.To migrate:
  1. Store optional integration credentials with fabro secret set.
  2. Re-run the GitHub App install flow if you want Fabro to write GitHub App secrets into the vault for you.
  3. Remove any server-runtime dependency on optional integration secrets coming from process env or server.env.
POST /api/v1/demo/toggle was removed. Demo mode remains available through the X-Fabro-Demo: 1 request header or a manually set fabro-demo=1 browser cookie.To migrate:
  1. Stop calling POST /api/v1/demo/toggle.
  2. Send X-Fabro-Demo: 1 on demo requests that should use fixture-backed behavior.

Provider-backed sandbox inventory

Fabro can now list managed sandboxes directly from configured providers instead of relying only on run projections. The new inventory API queries Docker and Daytona, returns partial provider failures in metadata, and can retrieve a specific provider-native sandbox ID when exactly one provider owns it. 
GET /api/v1/sandboxes
GET /api/v1/sandboxes/{id}
This gives operators a live view of the sandbox fleet even when a run record is missing, stale, or no longer the easiest way to answer “what is running right now?”

​
Settings can test models in place

Settings > Models now has a real model table, default and priority provider labels, and a Test models sweep that checks configured providers from the UI. The server exposes a provider test endpoint that returns per-provider results without turning one provider failure into a failed request. 
POST /api/v1/providers/test
The Settings area also gained a linked overview page and a cleaner navigation structure. Model configuration, integrations, monitoring, security, storage, and sandboxes now sit in a more predictable operations surface.

​
Run approvals are available everywhere

Pending runs can now be approved or denied from the CLI and MCP run tools, not only from the web app. That lets operators and agents move approval-gated workflows forward from automation scripts, terminals, or MCP clients. 
fabro approve <run-id>
fabro deny <run-id> --reason "Not approved for execution"
The runs list also exposes approval and delete actions closer to the rows you are already reviewing. Children now use the shared runs list view, with size sorting, per-row actions, and a simpler sub-tab toolbar.
