Module budget 

Shared limits for one public statement holding a write connection.

Both layers are required: an out-of-band watchdog calls sqlite3_interrupt, while SQLite’s progress callback enforces a VM-instruction ceiling and the same wall-clock deadline in-band. Every hook is stood down before return so an interrupt cannot bleed into the next statement on a pinned connection.

Constants

WRITE_DDL_TIME_BUDGET

DDL’s longer wall-clock fence while every other writer is quiesced.

WRITE_STATEMENT_TIME_BUDGET

Default public writer-statement wall-clock fence.

Functions

with_writer_statement_budget

Run one public writer statement under the standard DML or DDL limits.

with_writer_statement_limits

Run one public writer statement under caller-supplied limits. Exposed for deterministic boundary tests; production hosts normally use with_writer_statement_budget.
