Module transaction 

EditTransaction — the one and only way a buffer changes (ARCHITECTURE.md §8).

Every mutation, whoever authored it, is stamped with the buffer revision it was written against. That stamp is what makes agent diff-review safe: a proposal authored at version N can be carried forward through whatever the human typed since, instead of being written blind over their work.

Structs

EditTransaction

A change to one buffer, stamped with the revision it was authored against.

UndoGroupId

Groups transactions that undo together (ADR-0006 §6).

Version

Monotonic buffer revision. Bumps on every applied transaction.

Enums

EditSource

Where an edit came from. Agent carries the ProposalId so accepted agent edits stay traceable through undo history and review.
