Downstream-consumer run (roles 5/6b, public interface only) over the
document-authoring loop: canonicalization byte-exact and stable across
reformatting (F8), intrinsic validation thorough and path-addressed (F9),
referential tier correct across the project boundary with progressive
resolution (F10). Findings: one bug (F2: introspect --block advertises an
identity_id process ref the validator refuses), four frictions (F1 envelope
not derivable from introspection incl. the block-id/field-name mismatch and
the un-blocked seed; F3 content:-prefixed id vs bare-hash refs breaking
referential resolution silently; F4 --unwired only reports omitted refs,
which validate then fails; F5 strategy refs unresolvable from the public
surface — no blueprint register/file-content-id/param-space verbs), one
doc-gap (F6 no worked examples, metric vocabulary unlisted), and the
spec-gap F7: a valid, registered campaign has no run path — the
intent-persistence re-test the executor decision waited on.
