Status: BLOCKED — same OAuth failure as 2026-04-22, plus Cowork bash sandbox is out of disk.

TL;DR

Today's daily-negatives run did not execute. Two stacked blockers:

1. OAuth refresh token still invalid. The token in vault.env was already confirmed dead in yesterday's audit. No new SAIL_GOOGLE_ADS_REFRESH_TOKEN has been minted against the lunar-arc client since, so Backends 1 (google-ads-python), 2 (google-ads-mcp), and 3 (Pipedream) remain unreachable.
2. Cowork Bash sandbox is out of disk. Every Bash tool call returns ENOSPC. Even echo test fails. Independent blocker: even with a valid token, the sandbox cannot run google-ads-python or curl.

Additional constraint: the scheduled-task rules explicitly forbid Desktop Commander start_process with powershell.exe, pwsh, cmd.exe, .ps1, or .bat. That closed every Windows-side fallback path.

No budgets, bids, keywords, or negatives were changed. Report-only outcome per the "when in doubt, produce a report" rule.

What was attempted today

Backend 1 — Direct Google Ads API (google-ads-python)

• Bash sandbox required for pip install google-ads and python gads_client.py. Sandbox is ENOSPC. Cannot install or run.
• Even if the sandbox were healthy, the refresh token in vault.env is the same value that returned invalid_grant on 2026-04-22.

Backend 2 — Local google-ads-mcp (FastMCP)

• Source exists at C:\Users\SAguiar\Documents\Projects\_repo-staging\google-ads-mcp.
• Launch path requires pipx run --spec ... google-ads-mcp. The only available process launcher today (Desktop Commander) defaults to powershell and is disallowed by task rule.
• Same OAuth refresh token, same expected result.

Backend 3 — Pipedream MCP connector

• Pipedream Google Ads connector is not currently registered in the Cowork MCP list for this session.
• search_mcp_registry with keywords ["google ads", "pipedream", "adwords"] returned results: [].
• Cannot install without user present to authorize.

Backend 4 — Adspirer MCP (last resort)
