The operator's yes to take-over was refused twice (2026-10-26 13:48 and
2026-10-27 21:19 UTC) because 41 users differ, every difference a right the
grants part's list adds. The controller's list is not changed (ADR 0547 §1),
so ADR 0547 §8's equality could never hold again. ADR 0562 changes it:
take-over is allowed when no user is added or dropped, no loaded user loses a
publish, subscribe or responses right and every hash is held; the ask names
the added rights by user and kind, and a yes after they changed is refused.
Tests: rows from the captured live comparison of 21:19 (testdata, no
hashes) in the compare table, and rows in the take-over table for a right
removed, added rights changed since the ask, and only added rights recorded.
issue 1945
The user list of 2026-10-27 09:21 granted no holder for nine seats: the seeded
placements hold only the seats the controller had on record, and the grants part
read those holds as every holder (records.go heldWherePlaced). A placement's
holds are now the holders on record, as catalogue.World's Holdings are: a mesh
seat no placement holds is held by derivation, wherever its claimant is placed.
The membership loss guard (Losses) did not cover the user list: after take-over
the list that lost those seats went out. UserLosses applies the same guard per
user against the loaded list, and holdsBack holds a list that would lose a grant,
or whose loaded grants cannot be read, raising the held warning.
Quick fix chosen over moving the on-record rule into mesh-sdk: mesh-grants is the
only part reading placement holds itself; the others pass them to the catalogue.
