Task 2.1 (Req 1.1, 1.2, 1.5, 2.5).
- semantic/seed.py: export_mechanisms seeds only seeded/reviewed,
non-known-limit, parsing pairs with cached excerpts; every skip carries
a reason (tier, known_limit, parse_failed, language unsupported with a
degradation, pointer not cached, no labeled sink call site); runs
offline over the vendored catalog.
- variants.derive_shape: labels that name only a function and a mechanism
resolve to the fact-sink call inside that function (CWE match and a
non-constant argument first); line and sink intersect when both exist;
container reads are subscript or .get( only.
- append_from_pair keeps the strongest review tier and accumulates
provenance tags when a shape is re-seeded.
- CLI: `ousast mechanisms export --slice S [--store P] [--json]`.
