Transactions

Instant transaction builders and the commitTransaction contract.

Transactions

Commit helper

commitTransaction(transact, transaction, { onError }) → ok() or fail(message, error).

Pair with command-result.js: ok, fail, isOk.

Builders (`src/db/tx/`)

Module	Exports
`boards.js`	`boardTx`, `patchBoardTx`, `deleteBoardTx`, `deleteEventRowsTx`
`events.js`	`createEventTx`, `patchEventTx`, `saveEventTx`, `deleteEventTx` (+ optional ruleParams)
`prefs.js`	`upsertBoardPrefsTx`
`shares.js`	`createShareTx`, `patchShareTx`, `deleteShareTx`, `replaceShareTxs`
`theme.js`	`persistThemeTx` (null if no settings row)
`todos.js`	`checkTodoTx`, `uncheckTodoTx`

Invariants

boardTx creates board id + event txs and links owner
repeatEvery only written when truthy (schema rollout compatibility)
Patches whitelist fields
colorLabels object patches serialize to JSON string
Share editor mutations must include ruleParams.secret
replaceShareTxs deletes/recreates so editSecret cannot survive viewer demotion

Hooks

Feature hooks and what each one owns.

Testing

Vitest suites and the invariants they lock in.
