Phase 7 of S2b.
- API.md: "Form Builder" section rewritten with every new route
(schemas / fields / submissions / values / delegations / templates /
field library / webhooks / filter registry / public token flow).
Calls out §22.8 typed-confirmation deletes, §6.5 binding-change guard,
§9 signature hash on submit, §7.4–§7.5 FilterQueryBuilder contract,
and that FormSubmissionSubmitted is the trigger for the §31.10
TAG_PICKER sync listener.
- BACKLOG.md: FORM-02 marked done with the shipped artefacts and the
deferred §31.9 contract tests spelled out.
- ARCH-FORM-BUILDER.md §31.10 already rewrote authoritatively in Phase 2.
