Status: BLOCKED (3rd consecutive day)

Same OAuth refresh-token failure as 2026-04-22 and 2026-04-23. No ads changes made.

TL;DR

The daily-negatives tune-up did not run. The Google Ads refresh token in vault.env and Notion "A - Passwords" returns invalid_grant: Token has been expired or revoked. Root cause is unchanged: OAuth consent screen on project-claude-489923 is stuck in Testing mode, which forces a 7-day token expiry. The fallback lunar-arc-493119-a6 client has no refresh token on file.

New finding today. The Cowork Bash sandbox ENOSPC blocker from yesterday has been worked around. Python 3.14 at C:\Python314\python.exe now executes cleanly via Desktop Commander with shell pinned to Git Bash (C:\Program Files\Git\bin\bash.exe). Backend 1 (google-ads-python) runs end-to-end. The only thing stopping the daily run is a valid refresh token.

What was attempted

• Backend 1 (google-ads-python). Executed. Called CustomerService.list_accessible_customers(). Returned RefreshError: invalid_grant: Token has been expired or revoked. Definitive.
• Notion "A - Passwords" cross-check. Same expired token mirrored there. lunar-arc client has client_id/secret but no refresh token.
• Backend 2 (google-ads-mcp). Not attempted. Would inherit the same token.
• Backend 3 (Pipedream). Not registered in this session's MCP list.
• Backend 4 (Adspirer). Not attempted. Would inherit the same token.

What did NOT run

• Pass 1 — Search-term blocklist.
• Pass 2 — Cross-campaign cannibalization (brand/Spanish/geo).
• Pass 3 — Existing-negatives audit (Categories A–F).

Root cause

Unchanged across 3 days. project-claude-489923 consent screen is in Testing mode → weekly token expiry. vault.env was last modified 2026-04-16, exactly 8 days ago. Token died on schedule.

Permanent fix (15 minutes, Sam-only)

1. Google Cloud Console → lunar-arc-493119-a6 project → APIs & Services → OAuth consent screen → Publishing status → In production.
2. Complete verification if Google requests it for scope https://www.googleapis.com/auth/adwords.
