// SeedRepository is the seed aggregate: bootstrap ingest (seeds/*.yaml →
// DB) and the inverse export (DB → seeds/*.yaml for DR / version
// control).
//
// Each Ingest method is one transaction — parse, validate against the
// ontology, write, and record the file's content hash in seed_versions —
// and a no-op (applied=false) when the hash is unchanged, so re-running
// `oikos seed` is idempotent. Validation failures roll back the whole
// file. Ingest order across files (ontology before inventory) is a
// SeedService concern; within inventory, default checks derive only after
// relationships exist (a service inherits its container's address).
//
// Export regenerates the three structural seed YAMLs deterministically
// (sorted maps, ordered lists) so export → ingest → export is
// byte-stable. Runtime state (cognition layer) is excluded.
