Closing this for now. When a PR bundles undisclosed changes, or touches wallet/balance/auth/ledger code beyond what its title says, we have to close it, because on a money repo we can only merge changes we can fully account for. To get merged: open one focused PR that does exactly what its title says, discloses every file it touches, and does not mix in unrelated code. Small, single-purpose, honest diffs get reviewed and merged. Not a block, resubmit clean and it gets a fair look.
