- Added repeatable `--tag` argument parsing in `gen-npm-packages.ts` and threaded parsed tags into `generateNpmPackages` for targeted leaf publishing.
- Exported `prepareNativeCorePackage` and expanded package manifest typing to support scripted manifest rewrites used by release workflows.
- Reworked install-test smoke logic to pack the host leaf package, pack the rewritten natives core, and assert the platform leaf package resolves from the core optional dependency.
- Added `omp auth-gateway serve/token/status` — a forward-proxy injecting broker credentials for OpenAI Chat, Anthropic Messages, and OpenAI Responses wire formats.
- Added `GET /v1/usage` to auth-broker and auth-gateway; usage cache switched to 5-min per-credential TTL with jitter and last-good fallback on failure.
- Added `AuthStorage.setConfigApiKey/removeConfigApiKey/clearConfigApiKeys` so `models.yml` `apiKey` beats OAuth tokens without overriding `--api-key`.
- Added `omp auth-broker migrate --from-local` for idempotent upload of local SQLite/env credentials to the broker.
- Switched HL_EDIT_SEP initialization to read from process.env, trimming the value and defaulting to "~" when missing or invalid.
- Expanded the separator documentation with benchmark data and reliability notes explaining why "~" was selected as the fallback over other candidates.
