 ## Gotchas
 
-- `npm run build-css` copies `src/style/override/theme.config` into `node_modules/semantic-ui-less/` before compiling (mutates `node_modules`); output goes to `public/static/ui-render.built.css`. **`src/style/__tests__/setup.js` makes the same copy**, so an ordinary `npx jest` mutates `node_modules` too — which used to matter more than it looks: the webpack builds depended on that copy existing, because `theme.config` is aliased to our own file and its `@import "theme.less"` resolves relative to the importing file, where no `theme.less` exists. `verify` passed only because `test:coverage` runs before `build`; a job going straight from `npm ci` to a build failed. Fixed 2026-09-02 by giving less-loader `paths` in both webpack configs, so a build no longer needs the copy — but the test-time mutation is still there.
+- `npm run build-css` compiles `src/style/index.less` to `public/static/ui-render.built.css`. **It no longer mutates `node_modules`,** and neither does `npx jest`: both used to copy `theme.config` into `node_modules/semantic-ui-less/` because Semantic's definitions import it from inside their own package. §9.7-F1 step 4 removed the package, so the copy, the shared helper that made it and the three webpack `theme.config` aliases are all gone. The jest `setupFiles` entry survives as a documented no-op.
 - Jest has no path-alias mapping (`jest.config.js`) — only relative imports resolve in tests.
 - `isFunction()` from core utils rejects cross-realm functions such as `jest.fn()` — use plain functions in tests.

   **AND ONE TRAP IN THE GATE ITSELF, worth recording because it looked exactly like a product bug.** Two separate false alarms came from the measurement, not the CSS. The generator detects live imports by line shape; it did not recognise `@import (multiple) "..."`, so the baseline compile kept our overrides while the full compile also had them — 47 rules subtracted themselves away and the gate reported them MISSING FROM THE OUTPUT when they were only missing from the MEASUREMENT. Earlier, two of the four apparent "duplicates" turned out to occur twice on master as well; chasing them cost real time. A gate that measures by difference needs its difference to be exact, and both lessons are now comments in `generate-semantic-css-fixture.js`.
 
-  What remains of step 4: deleting `semantic-ui-less` and its `theme.config` machinery — three webpack aliases (the plan names two; `webpack.watch.config.mjs` is the third), the `node_modules` copy in `scripts/install-theme-config.js` and its three call sites, and the now-unreferenced `override/` tree.
+  **THE DEPENDENCY IS GONE — STEP 4 COMPLETE (2026-09-15).** `semantic-ui-less` is out of `devDependencies` and out of `package-lock.json`, and the published `static/all.css` still has the SAME sha256 (`dcdb0a40…`) it had before any of step 4 — the whole exit is invisible to a consumer's rendering.
+
+  What went with it: **three** webpack `theme.config` aliases (this plan named two — `webpack.watch.config.mjs` was the third), the `node_modules` `lessOptions.paths` entries in the demo and library configs, `scripts/install-theme-config.js` and its three call sites, and **89 of the 97 files** under `src/style/override/`.
+
+  **The deletion was decided by the import graph, not by reading.** `less.render` reports the files it actually read; run against `index.less` it showed 0 `semantic-ui-less` files and only 4 live files under `override/`. Eight are kept: those four plus the four inputs the vendoring compile reads (`globals/reset.variables`, `globals/site.variables`, `modules/dropdown.variables`, `theme.config`) — kept deliberately so `scripts/vendor-semantic-css.js`'s stated recipe (`npm i --no-save semantic-ui-less@2.5.0 && node scripts/…`) remains TRUE rather than becoming a note about git history. Vendored third-party code without a reproducible derivation is a dead end.
+
+  **`npx jest` no longer mutates `node_modules`** — the gotcha CLAUDE.md carried for months. The jest `setupFiles` entry survives as a documented no-op.
+
+  **The LESS 3 pin does NOT dissolve with the package**, which this plan predicted it would (R8, §9.8). Both anchors turn out to be ours, measured: `javascriptEnabled` is required by `_variables.less:23` and `less-plugin-functions` by `round()` at `_variables.less:264`. Unpinning LESS is separate work with two named targets.
+
+  One thing CI caught that a local check had missed: `lint:css` globs `src/style/**/*.less`, so the vendored files entered it and reported 2,295 violations of conventions upstream never followed. `.stylelintignore` excludes `src/style/vendor/` — generated third-party CSS is not where style decisions are made. The local check had been `npm run lint:css | tail -1`, which shows output and hides the exit code; gates are verified by exit code now.
 
 - **Step 5 — cleanup + release.** The `semantic-ui-react` dependency is already gone (Step 3½); this step drops `semantic-ui-less`, finishes changelog + supported-prop documentation, and records the bundle delta (−30 KB+ per the source's own estimates: 27 KB Dropdown + 4 KB Table + Popup). **SEMVER — DECIDED (2026-09-11): this ships as a MINOR.** The maintainers' call, and it is recorded here so the earlier reasoning is not mistaken for the decision. What the plan said before: Step 0 found no unsupported passthrough props in the wild, so on that evidence a minor — with the tier-2 decision as what could turn it major, since dropping a published propType is breaking even when nothing observed uses it. Steps 2 and 3 then did drop published propTypes (19 tooltip names, and `search`/`multiple`/`allowAdditions` with their companions), and the analysis in those steps argued for a major on that basis. The owners weighed it against the evidence that nothing in either corpus or the consumer-only record declares any of them, and chose minor. `docs/SUPPORTED-PROPS.md` still carries the full `Dropped` inventory per component, which is where a consumer looks regardless of the version number.

+  `semantic-ui-less` at build time. Their output now lives in this repository, and the package is
+  removed.
+
+  The evidence that this is invisible to you is the strongest kind available: the published
+  `static/all.css` is **byte-for-byte identical** — same SHA-256 — before and after. Not "looks the
+  same"; the same file.
+
+  What this means in practice: installing this library no longer pulls Semantic UI in any form,
+  and the LESS toolchain no longer writes into your `node_modules` during a build or a test run.
+  Attribution for the vendored CSS is in `THIRD-PARTY-NOTICES.md`, which ships with the package.

+ * Semantic's definition files import `'../../theme.config'` from inside their own package and the
+ * package ships only `theme.config.example`. That made an ordinary `npx jest` MUTATE `node_modules`
+ * — a gotcha this repository documented in CLAUDE.md and worked around in three places.
  *
- * What this file keeps is the note about WHERE it runs: once per jest WORKER, which is why the
- * shared helper skips the write when the destination is already correct and renames a
- * process-unique temp file into place when it is not.
+ * §9.7-F1 step 4 removed the need: the CSS those definitions produced is vendored under
+ * `src/style/vendor/`, nothing imports `semantic-ui-less` any more, and the package is gone from
+ * `devDependencies`. No test writes to `node_modules`.
+ *
+ * The file stays because `jest.config.js` names it in `setupFiles`, and an empty hook is a cheaper,
+ * more obvious place for the next global test-time setup than a config edit plus a new file. If
+ * none arrives, delete both together.

+  WHAT THIS FILE IS NOW. It began as semantic-ui-less's own "import the modules you need" manifest,
+  a list of ~50 commented-out `@import`s reaching into `node_modules`. §9.7-F1 step 4 finished the
+  exit: the two modules that were still live are compiled into `src/style/vendor/`, the package is
+  gone from `devDependencies`, and the commented list went with it — leaving it would have offered
+  a menu of imports that can no longer resolve.
+
+  What remains is the seam: the vendored CSS, each followed by OUR overrides for it. The
+  `(multiple)` on those imports is load-bearing, not decoration — see the note beside them.
