Orchestrates per-purpose subject resolution + binding conflict
resolution + per-binding writes per RFC Q4/Q7/Q9. Per-binding failures
captured in BindingPassResult, not thrown — partial failures are
expected and recoverable. Catastrophic failures (no transaction,
unknown purpose, missing schema) throw FormBindingApplicatorException
and bubble.
Per-strategy null-winner matrix implemented via a NO_OP sentinel:
overwrite=write null, append=noop, replace=conditional, first_write_wins=
write only into null target. Append is collection-only with set-merge
semantics (deduplicated array_merge).
Identity-key bindings are skipped during apply — the subject resolver
already used them for lookup/provisioning; re-writing is a no-op or a
clobber.
Activity log hierarchical: one bindings_pass_completed parent +
N binding_applied children with parent_activity_id linkage (RFC Q12).
Failed bindings get error_class/error_message in their activity entry
in addition to their FormSubmissionActionFailure row (deliberate
dual source of truth).
