 ## Details
 
+### 42. Lower the reading cost of the files a chunk reads most before its first commit.
+
+`reading-cost` (`docs/reading-cost.md`) reports the figure rising: the last 5 chunks' median is
+98975 new input tokens before their first commit, the 5 before them 80251. Read most over the last
+5 chunks (opens and searches): `README.md` 27, `todo.md` 24, `src/http/app.test.ts` 10,
+`examples/plugins/admin/admin-users.ts` 8, `e2e-tests/full-flow.spec.ts` 7, `ci.sh` 5,
+`CHANGELOG.md` 4, `e2e-tests/visual.spec.ts` 3, `examples/plugins/admin/admin-groups.ts` 3,
+`examples/plugins/admin/admin-users.test.ts` 3. Make the most-read files cheaper to find one's way
+in, such as splitting `src/http/app.test.ts` by concern, and run `reading-cost --reset` in the chunk
+that ships this.

 ### 3. Guard the group paths against self-lockout, or accept the gap explicitly.
