+## IndeeHub native login and registration repair — 2026-10-09 follow-up
+
+ngit proposal `9d6de783f5022b3b859e0b1f3e881e389da4482dd5dd15ff29a40b4e25dafcb8`
+was reviewed and merged once as
+`83feb1806336a1204ea0d6232de5220d4f6656ad`. It retains installed/running
+parent, existing node identity/pin, installed origins and legacy API component
+checks while accepting managed stacks without a separate API package record.
+See the latest checkpoint in `post-1.8.22-regressions-20261001.md` for exact
+deployed hashes, preserved-state checks, backups and the failed earlier probes.
+
+Yaya's authenticated registration-context RPC now passes on the optimized
+candidate backend. Real native **Home Serve** authentication passes after
+IndeeHub frontend `7b18912` and API profile correction `08586e3`: chosen node
+key, signed session subject and API profile key match, with native consent and
+normal signer dismissal. Frontend 21 focused tests, API two DTO tests, and both
+production builds pass. The isolated Rust regression build is still running;
+no unit-test pass is inferred from the live check.
+
+The frontend/API module changes are running-container UAT patches, not a new
+durable pinned app image. Full upload/publication and cached-identity-switch
+acceptance remain open. No payment, public listing, identity replacement, fleet
+catalog, OTA or ISO publication was performed by this repair.
