Limit sign-in to the company's email domain, twice: in blocking functions and in the rules.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Company domain only
0. Blocking functions need the projects upgraded to **Firebase Authentication with Identity Platform**. Run
`sh <usecase pack>/checks/identity-platform.sh dev prod` (with `BLUEPRINT_BASE` / `BLUEPRINT_USECASE` set to
the two pack paths): it reads each project and names only the ones not upgraded yet. Ask the user only if it
fails, giving them exactly the URLs it printed — the upgrade is free at this size, but it is a click only they
can make.
1. In `functions/`, add `beforeUserCreated` and `beforeUserSignedIn` (from `firebase-functions/v2/identity`).
Both throw `HttpsError("permission-denied")` unless `event.data.email` ends with `@<domain>` AND
`event.data.emailVerified` is true. Compare lower-cased.
2. If the spec says Google Workspace, also pass `hd: <domain>` to the Google provider. That is a hint to the
account picker, not a check — the functions are the check.
3. Copy `infra/firestore.rules` from the internal pack into the project, filling `{{DOMAIN_REGEX}}` with the
domain in lower case with its dots escaped. First check the domain is only DNS labels

How to install
mdr add receptron/mulmoterminal/blueprint-internal-domain-restriction@sha256:60e86b11f09f0329The line at the top of this page pins the label git:20260926.967190d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
