# Architecture

  -> NZFC-GRAM runtime
  -> scoped SQLite memory
  -> static NZFC archive assets
  -> large-document SQLite FTS5 index
  -> tombstone guard
  -> exact slot mapper
  -> malicious-memory redaction
  -> bounded evidence pack
  -> optional DiffusionGemma generation
```

Memory is evidence, not instruction.
