tests/determinism.rs (3 cases):
- same input across 2 isolated tempdirs → byte-identical output
- same input across 10 isolated tempdirs → all byte-identical
(catches HashMap iteration nondeterminism a 2-run check can miss)
- reordering blocks in the manifest changes output, but only in the
block region — frontmatter + role + trailing sections are stable
tests/roundtrip.rs (2 cases):
- every manifest string (name, model, tools list, all domain_in /
forbidden_domain / handoff.target / handoff.trigger entries)
appears verbatim in the generated output; no field silently dropped
- two consecutive runs in the SAME tempdir produce identical bytes
(defence against caching / mutable-global drift)
tests/validator_negative.rs (6 cases):
- unknown block ref → error mentions the bad name
- missing obligatory block (memory-protocol removed) → error names it
- empty handoff array → error mentions "handoff"
- whitespace-only role → error mentions "role"
- empty domain_in → error mentions "domain_in"
- --validate flag on a valid manifest: exit 0, no file written
Not covered: unsubstituted `{{placeholder}}` check — that validator
rule is being added in a parallel PR (fix/remaining-findings) and is
not yet on this base branch. Add a case for it when the check lands.
