transactql
Compose a multi-step write to a Clef app as a single atomic Transaction using transactQL (the EdgeQL-style DSL) or transact(ops:) (the explicit Op[] form). Use whenever a fix touches >1 concept / >1 file / requires a precondition / would otherwise be a stack of separate Edit/Write calls. Atomic, idempotent on retry, dryRun-previewable, rolls back on failure.
