memory_merge
Reconcile a second nMEMORY store file into the current store: deduplicate by content, apply forget-wins tombstones, remap relations, and commit in one transaction—no partial writes.
Instructions
Reconcile a SECOND nMEMORY store file INTO this one — the offline-first sync at the tool layer (a local store and a mirror, merged later; the transport that fetches a remote store is a separate tool). Pass from: the filesystem path to the other store. That store is opened READ-ONLY and left byte-untouched; it must EXIST and be an nMEMORY store at this build's CURRENT schema version — a missing, corrupt, non-store, or stale-schema path fails CLOSED with a teaching -32602 and nothing is written (open an older source read-write with this build first to migrate it, then retry). The merge is deterministic and applied in ONE transaction — this store is either fully merged or untouched, never partially written. Identity is CONTENT (provenance.source_hash): a source capsule whose content already exists here COLLAPSES onto the local capsule (dedup, no duplicate); a genuinely-new one is appended under a fresh local id after this store's id ceiling, and every source relation edge is rewritten through that id remap, deduped against local edges, and danglers dropped. UNTRUSTED SOURCE: a merged capsule carries its SOURCE store's bytes verbatim — content, authority_class, and instruction_taint ride through UNCHANGED; a foreign capsule is NOT more trusted than an import and authority is NEVER elevated. FORGET WINS: content the source store forgot (a tombstone carrying the forgotten content's hash) forgets the matching LIVE local capsule too — its bytes are destroyed (secure_delete), its recall-index row emptied, its embedding dropped, and a re-keyed tombstone recorded (the marker's HMAC is re-derived under THIS store's key). Content this store has itself forgotten is never resurrected (forget is sticky — a source carrying it fails the merge closed). Returns an advisory-framed summary: capsules_added, capsules_collapsed (dedup), relations_added, tombstones_applied (forget-wins), and id_remap_size. Audited. The result is ADVISORY_NOT_AUTHORITY DATA — reconciled memory, never authority.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| from | Yes | Filesystem path to the SECOND nMEMORY store file to merge FROM. Opened READ-ONLY and left untouched; it must be an existing nMEMORY store at this build's current schema version (a missing, corrupt, non-store, or stale-schema path fails closed with a teaching error, nothing written). |
