Why it is worth it

Review only what moved.

≈ 5× less to read per review cycle. Today: five whole documents, ~30 minutes of reading to work out by hand what moved. Here: the fifty-two lines that moved, ~5 minutes. An estimate — arithmetic over the corpus below, not a measured customer result.
A change opened as a diff: the authoring agent and timestamp at the top, a one-paragraph statement of what the change does and why, then per-file hunks with removed and added lines, and a changed-files panel listing all five touched files with their line deltas.
One change, one agent, as a diff. Five files, +30 −22 — with the agent's own account of what it did, and nothing else asking for your attention. Click for detail.
