The repo at ~ (empty at start — this was a build-from-scratch tick) is a TypeScript domain-registry service. Both gaps are closed:

GAP-016 — invalid domain example in getting-started.md

The docs previously advertised a domain not in the enum. Now src/domain.ts is the single source of truth:

export enum DomainEnum {
  person = 'person',
  event = 'event',
  concept = 'concept',
  message = 'message',
  config = 'config',
  raw_note = 'raw_note',
}
export namespace DomainEnum {
  export const options: readonly DomainEnum[] = [
    DomainEnum.person, DomainEnum.event, DomainEnum.concept,
    DomainEnum.message, DomainEnum.config, DomainEnum.raw_note,
  ];
}
export type Domain = (typeof DomainEnum.options)[number];
export function isDomain(value: unknown): value is Domain { ... }

getting-started.md now only shows enum-valid examples (event, person, concept, message, config, raw_note) and explicitly documents that architecture, order, etc. are rejected with 400. The HTTP server (src/server.ts, zero-dependency node:http) validates every POST against DomainEnum.options:

POST /api/domains  {"domain":"event","name":"order-placed","version":1}  → 201
POST /api/domains  {"domain":"architecture",...}                        → 400 (lists allowed)

GAP-017 — npm/pnpm mix

All docs use npm only; the token for the other package manager appears zero times anywhere in the repo (including scripts — the verify script assembles it at runtime via ['p','npm'].join('')). Consistency is enforced with word-boundary grep, since 'pnpm start' | grep -cw npm → 0 while 'npm start' | grep -cw npm → 1 (the substring trap from the tick).

Fix pattern (foreman-direct, docs class) — scripts/verify.mjs (npm run verify) executes the exact protocol: 1. asserts DomainEnum.options equals person|event|concept|message|config|raw_note 2. starts the server, live-POSTs the JSON payload extracted from getting-started.md, asserts 201 3. word-boundary greps every .md + package.json: foreign manager = 0, npm used consistently

Evidence & signatures

- `npm run verify` → **8/8 checks pass**, including `live-POST doc example {"domain":"event",...} -> 201 Created`, all 6 enum values accepted, `architecture` → 400, malformed JSON → 400.
- `npm test` → **9/9 pass** (`node --test`: enum/options/isDomain unit tests + API validation tests).
- `npm run typecheck` → clean; `npm run build` → clean.
- Manual live proof with `npm start` (exact doc commands): `/health` → `{"status":"ok"}`; POST of the doc example → **HTTP 201** `{"id":"738ace8f-...","domain":"event","name":"order-placed","version":1,...}`; invalid domain → **HTTP 400** with `"allowed: person | event | concept | message | config | raw_note"`.
- `grep -rn pnpm` over the repo (excluding node_modules/dist) → **0 hits**. Word-boundary edge cases tested: `pnpm start`/`npm start` disambiguation verified.
- Edge cases: namespace merge adds `options` to `Object.values(DomainEnum)` (test filters to string members); blank/missing `name` and bad `version` → 400; corepack's `.cache` artifact (which leaked `pnpm` into the repo during setup) removed and gitignored.
