The jscpd gate flags the deliberately mirrored open/stamp sequence against session-persistence-sqlite and session-query-sqlite. The copy is the settled this-phase choice — this group is the third user and the shared medium helper is deferred to the log-facet migration so the session packages stay untouched (reuse audit in the design note); mark the span accordingly.
storage/ — non-session storage family
The storage family persists everything that is not a session event log: a hub where named backends and typed data forms meet. Design record: domain KV storage Agent Note.
| Package | Role | ctx key |
|---|---|---|
storage/ |
The hub: named backend registry + merge-extensible data-form mounts, backend facet vocabulary, shared conformance suite | ctx.storage |
storage-json/ |
JSON backend: one human-readable file per unit, atomic whole-file rewrite | registers backend json |
storage-sqlite/ |
SQLite backend: one database hosting all routed units, document-per-row | registers backend sqlite |
domain/ |
Domain data form: zod-validated records, per-domain write chain, domain/changed events, backend routing by configuration |
mounts ctx.storage.domain |
Backends own one medium each and expose data-shape facets (kv today; an append-log facet is reserved for the future session-backend migration). Consumers never touch backends directly — they open declared domains through the domain form.
