wcl diff (WAD usage)

command

Diffs two WAD revisions over the evaluated views — the seam the change workflow builds on.

wcl diff <rev>:wad.wcl wad.wcl compares the *evaluated* documents: the git side materialises that revision's whole tree (so imports — including committed generated data — resolve from it), and formatting-only churn produces no diff. Entities key as kind:label; field edits report by path with old/new values; --format json for tooling.

For change management it is one of the delta sources the spec-writing LLM reads (alongside git diff, and seeded by wcl wad spec --from <rev>), and it is the fast answer to “what changed since the review?”. General diff semantics live in the wcl wskill.
