about

AUTHORED BY THE NISHI BUILDER (nx_module_author_data sqlite-read template) -- ELDERMIG E1 rung 1. Sovereign READ-ONLY SQLite reader: header check, table-btree walk (leaf 0x0D / interior 0x05), sqlite_master record decode (type/name/rootpage), per-table row counts. Additive law: read-only. HONEST LIMIT (raised hand for rung 2): local payload only -- overflow pages not followed yet; fine for sqlite_master scans of Elder DBs; full row/column reads = rung 2.
