-- 32_samplerequestimport.sql
-- Sample Request Import
--
-- GENERATED by _gen/pack.py from ../step/. DO NOT EDIT -- edit the source
-- there and re-pack, or the sha256 in MANIFEST.md stops matching.
--
-- 5 table(s), 20 ledger step(s).
--
-- ⚠ IMPORT ORDER: 01_system.sql, then all seven 1x masters, then this file. Order among
--    transactions does not matter. Re-importing costs nothing.
--
-- ⚠ STOP ON THE FIRST ERROR. Do not use `mysql --force`, and do not tick any
--    "continue on error" box. Each step records itself in `_migration_ledger`
--    immediately after its statement runs, WITHOUT checking that the statement
--    succeeded -- that is inherited from step/, where run.sh guarantees a stop by
--    running mysql without --force. Continue past an error here and a step that
--    failed is marked applied: 99_finalize.sql will then seed `migrations`, and
--    `php artisan migrate` will skip the work still owed. Both default clients
--    stop on error; the danger is turning that off.
--
-- ⚠ phpMyAdmin: UNTICK "Allow the interruption of an import".
--    If it fires, the import resumes on a NEW CONNECTION: SQL_MODE reverts to the server
--    default and every @variable dies, mid-file. Two things then break. NO_ZERO_DATE is
--    back, so any ALTER that rebuilds a table holding '0000-00-00' fails with ERROR 1292.
--    And @step / @todo / @sql are NULL, so the guard around the next payload stops meaning
--    anything. The SET SQL_MODE before every unit below limits the damage when someone
--    forgets the checkbox; it does not replace unticking it.
--
--    (STRICT_TRANS_TABLES is forced for a third case -- a value too big for its new column
--    is CLAMPED silently rather than refused. Measured on the tree as it stands, no column
--    narrows: all 674 MODIFY COLUMNs widen or are no-ops. It stays forced because the next
--    regeneration is under no obligation to keep that true.)
--
-- ⚠ Take a full backup first. The `20_cleanup` steps change data and nothing here
--    reverses them. `../audit_bukanmain_before_migrate.sql` only reads.
