The four identity fields (tracking_number/title/revision/status) come from the
filename — the single source of truth that the register/WORM/ACL key off, never
the front matter. But they must stay in the front matter for the converter's
title block. Resolve the long-standing "front matter disagrees with filename"
nag without coupling the system to ZDDC naming:
- Sync-on-open: when the filename is ZDDC-parseable, mirror its identity into
the front matter on open; if that corrects anything the buffer opens dirty so
a save bakes it in. No-op for non-ZDDC names — the editor stays fully usable
on arbitrary directories, where the front matter is the sole source.
- A manual edit to an identity field is treated as a cue to RENAME the file
(the filename owns identity), not a value to keep: the old "filename wins,
ignored" warning is replaced by an explicit "Rename file & reopen" button
that saves, renames to the implied ZDDC name, and reopens it (server mode via
the ?file deep-link; FS-Access via the moved handle).
- Reword the RecognizedFrontMatter hints from "the filename wins on mismatch"
to "mirrors the filename — rename the file to change it".
