Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. db.NewTransaction creates read-write transaction that persists key-value entries upon Commit
  2. db.NewTransaction creates read-only transaction that retrieves values via Txn.Get and Item.ValueCopy
  3. Txn.Get returns badger.ErrKeyNotFound for non-existent keys
  4. Read-only transactions return badger.ErrReadOnlyTxn on write operations Set and Delete
  5. Txn.Delete removes existing entries in a read-write transaction upon Commit
  6. Txn.Discard aborts uncommitted modifications without altering the database
