Module wrappers 

Wrapper tracking — NIP-59 gift wrap dedup + NIP-77 negentropy.

Constants

TRANSPORT_CONCORD

TRANSPORT_NIP17

Transport carriers for the shared outer-event ledger — stored as a small INTEGER discriminator (cheaper than a per-row string, and the ledger can grow large). Never renumber an existing value.

Functions

load_negentropy_items

Load all processed wrappers as (EventId, Timestamp) pairs for negentropy (NIP-77).

load_processed_wrappers

Load all processed wrapper IDs as raw bytes for the dedup cache.

load_recent_wrapper_ids

Load recent wrapper IDs from events table (last N days) as raw bytes.

processed_wrapper_exists

Sync existence check against the ledger (any transport) — the DB half of the outer-event dedup for callers that can’t reach the async WRAPPER_ID_CACHE (e.g. the synchronous Concord ingest). Returns false on a missing/closed DB so a dedup failure never drops a genuinely-new event.

save_processed_wrapper

Persist an outer-event id for cross-session dedup (INSERT OR IGNORE), tagged by transport so the ledger is shared across transports while negentropy stays NIP-17-scoped.

update_wrapper_timestamp

Upsert a wrapper timestamp (backfill for pre-migration-17 wrappers).
