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. assert sqlite driver connects to in-memory database and executes JSON functions including json_extract, json_object, json_array, and json_patch
  2. assert STRICT table schema enforces strict column type checking on INSERT operations
  3. assert STORED and VIRTUAL generated columns automatically compute derived column values from base row expressions
  4. assert INSERT, UPDATE, and DELETE statements with RETURNING clause return modified row columns without secondary queries
  5. assert json_each table-valued function expands JSON arrays and key-value objects into relational rows
  6. assert UPSERT with ON CONFLICT DO UPDATE correctly updates existing rows using the EXCLUDED pseudo-table
