Records controller v0.188.0 across the four coupled artifacts.
07-backup-architecture.md is the owning doc:
- new 7.4 = the recovery chain AFTER D5 (7.1 leg 1 superseded; leg 2,
the living-app dependency, explicitly unchanged so this is not read
as more than it is)
- 7.3 collapsed to history, with the correction that the target as
written (data_key-only) was tested in Part 0 and rejected
- 3 records that the two-lane split is now real, not just intended
- matrix rows 3 / 3c (new) / 13; 10.1 D5 itself shipped
Also: new capability-map row, D5 collapsed in ROADMAP + OPEN-ITEMS,
and R-127 filed in both (data_key flag unreliable; O4 can regenerate a
DB password that no longer matches the restored data directory).
The audit is named D5-drive-alone-restore rather than "...secrets..."
because .gitignore blocks *secret* -- a guard worth respecting, not
forcing past.
