Model the collections from the spec and open each one explicitly in firestore.rules, proven by emulator tests.
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
# Data model and security rules The spec has a table per collection: who may read, create, update and delete. That table IS the rules. 1. For each collection, add a `match` block above the final deny-all. Open only what the table says. 2. On create, pin ownership (`request.resource.data.ownerUid == request.auth.uid`) and the fields a client may set (`request.resource.data.keys().hasOnly([...])`). 3. On update, forbid changing ownership and any field the table does not let that role change (`diff(resource.data).affectedKeys().hasOnly([...])`). 4. Write `test/blueprint/rules.spec.ts` with BOTH directions for every row of the table: the allowed operation succeeds (`assertSucceeds`) and every other role is refused (`assertFails`). A rule with only a success test is not tested. 5. If the table is ambiguous, ask — do not open more than it says. Done when the check passes: `emulator-test.sh rules`. ## Always - Read `.blueprint/spec.md` first. It is the agreed specification; do not widen it. - When you need a decision, ask it through the blueprint question tool and stop. Do not guess. …

How to install
mdr add receptron/mulmoterminal/blueprint-firebase-data-rules@sha256:fe4b659b0dfb3da2The line at the top of this page pins the label git:20260925.6ec9326, 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.
