 ## Details
 
-### 126. Decide whether `.oxlintrc.json` may hold the import boundaries, and hold them there.
-
-Two boundaries in `docs/decisions.md` §The source parts by ADF and format hold by convention only:
-`src/markdown/parse/` imports from `src/markdown/emit/` only `emit/spelling-questions.ts`, and
-`src/markdown/directive/` imports neither `emit/` nor `parse/`. The technical principles refuse a
-test that scans the source: principle "Assert the outcome" bans it. oxlint 1.89.0 can hold both
-boundaries with `overrides` carrying `no-restricted-imports`. Verified: a forbidden import fails
-the `size-ratchet` leg in each form, as `from '…'`, as a bare `import '…'`, with a double-quoted
-specifier and as a dynamic `import()`. An import of `../emit/spelling-questions.ts`, listed as the
-exception, passes.
-
-But the maintainer's §The size ratchet gives `.oxlintrc.json` a single rule and says no second
-lint rule joins it. The question for the maintainer: may the config hold a second kind of rule, the
-import boundaries? If so, amend that entry's "single rule" and "no second lint rule", and rename the
-`size-ratchet` script and `ci.sh` leg, whose name would no longer say what they hold.
