- .wob v3: class records carry an index tail (flags bit0 = unique, col_cnt, columns) -- @table(index:[a,b]) entries plus one unique single-column entry per @unique field; loader validates columns in range and scalar/Text-kinded; emitter validates the declarations (unknown column, un-indexable kind => diagnostic) - engine: db_index hash multimap per table, built from the class table at first touch, maintained ONLY inside wo_row_insert/ wo_row_remove; unique checks re-compare actual column values (a hash is a hint); replay re-indexes via wo_row_raw_commit AFTER slots are filled, so recovered tables carry their indexes - WO_T_UNIQUE = 10; a violating insert is un-applied whole (bitmap, hash, count, and the never-observable id reclaimed) and traps catchably -- the employee SEED-DUP pattern - wo_row_insert gains err_kind so db.c maps UNIQUE/OOM/other to the right trap; test images and the runner's loader mirror speak v3 - fixtures: trap/db-unique-violation (code 10 exact) and run/db-unique-catch (catchable dup, composite index accepts duplicates, next id dense after a refusal) - gates: oop-e2e 73/0, all 15 runtime suites, woc-test green, log-watcher 7/0 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

-- iteration 9 Task 4, the other half: the unique trap is catchable (the

|
-- employee sample's SEED-DUP pattern), a NON-unique @table composite index
|
|
-- accepts duplicates, and a distinct key inserts freely beside the taken
|
|
-- one. (Key release after delete joins the corpus with Task 5's delete.)
