Module tables 

fz tables diff and fz tables drift — what a declaration change costs, and what a database differs from the declaration by.

Both halves of this landed without a way to run one against the other: a manifest can declare [tables] (#354) and cratefield_introspect::drift can compare a declaration against a live catalog (#353). This is the command that makes the pair reachable by a person, which is the only form in which either is worth anything.

Read-only, always. It opens the database, reads its catalog and prints; there is no --fix, because what a drift costs is the author’s decision and three of the four answers are not “apply this”.

Functions

diff

fz tables diff: what changed between two versions of a manifest’s declaration, and what each change costs.

diff_report

Reports the differences and answers how many there were.

drift

fz tables drift: report, then fail when there was anything to report.

drift_report

Reports drift between the manifest at manifest_path and the database url names, and answers how many differences there were.
