Fix red develop a70e3ad3de8c

The merge lane found `develop` red at `a70e3ad3de8ce56158a7ac4a1a5d61399128b1bf` on its own: no queued PR merges until it is fixed. Failing (tests and gate stages): - `mirror-trees-strict` - `community-edition-tooling-suite` - `org-transfer-rule-tables` - `nodevault-interop-guard` The whole gate log: artifact `13759` on lane task 12311. Make `develop` pass its full gate again. Open a PR as usual: the merge lane merges a PR that fixes some of these and adds no failure even while `develop` is red.

Fixed red develop: restored NodeVault interop seams deleted by Task 12306; named Production QA stubs and outcome_ledger/tick.py as CE entrypoints; transfer rules already fixed by 6b824dd45. Quick gate + 4 stages green; PR #7610 queued. Memory: none applied.
