 Run `npm run build` before any live `bench:run` if you want `src/` changes reflected; the bench does not run from source.
 
 Prefer this project's own CLI for pull requests — it is the tool being built, so opening its PRs with it is the dogfood path:
-`npm run build && node dist/main.js pr create --login axi --base main --head <branch> --title <text> --body-file <path>`.
-The login profile is named `axi`, not `alexion` — passing `--login alexion` fails with `VALIDATION_ERROR`.
-It reuses the `tea` login profiles, so it needs no separate credentials.
-Fall back to `tea pr create --login axi --base main --head <branch>` only for what gitea-axi cannot do yet; `tea pr` still lists PRs until `pr list` lands (task 0008).
+`npm run build && node dist/main.js pr create --login alexion --base main --head <branch> --title <text> --body-file <path>`.
+It reuses the `tea` login store, which here holds exactly `alexion` and `csv-reviewer` — there is no `axi` profile.
+`selectLogin` matches the `--login` value against those names exactly, so `--login alexion` works and an unknown name like `--login axi` fails with `VALIDATION_ERROR` ("Login profile "axi" not found").
+Fall back to `tea pr create --login alexion --base main --head <branch>` only for what gitea-axi cannot do yet; `tea pr` still lists PRs until `pr list` lands (task 0008).
+
+The same login store backs the benchmark: `npm run bench:run -- --arm <arm> --login alexion --task <id>` (or set `GITEA_AXI_BENCH_LOGIN=alexion`).
+
+The `bench/` unit tests only run under their own Vitest project config: `npx vitest run --config vitest.bench.config.ts bench/<file>.test.ts`.
+Plain `npx vitest run bench/<file>.test.ts` reports "no tests" because the default `vitest.config.ts` includes only `test/**`.
 
 Task branches are merged into `main` on the remote, so the local `main` goes stale.
 Always `git fetch origin` and cut a task branch from `origin/main`, not from whatever local `main` happens to point at.
