Zapier is one ingress. Direct web, customer API, and S2S leaf nodes are their own services. Every hop to an internal subject must pass verae.access.authz.check (default deny by plane).

# verae-access-authz
|
|
|
|
Authorization step on the NATS **address path**. Zapier is only **one** access plane. Direct web, customer API, and server-to-server leaf nodes are separate, and each is default-deny against internal subjects.

## Address path
|
|
|
|
```text
|
|
client
|
|
→ verae.access.<plane>.<area>.<resource>.<action> (ingress, that plane only)
|
|
→ verae.access.authz.check (allow / deny)
|
|
→ verae.<area>.<resource>.<action> (internal bus)
|
|
```
|
|
|
|
Internal subjects (`verae.billing.*`, `verae.archive.*`, `verae.zapier.jobs.*`) stay stable. Planes never publish them until `authz.check` returns `allow`.
|
|
|
|
| Plane | Who | May reach |
|
|
|-------|-----|-----------|
|
|
| `zapier` | Zapier Platform HTTPS | jobs.*, webhooks.deliver, billing.usage.recorded |
|
|
| `web` | Customer browser portal | statement.get, balance.adjust kind=reload\|payment |
|
|
| `api` | Customer `x-api-key` (not Zapier) | statement.get, usage.recorded, jobs.watch |
|
|
| `leaf` | S2S NATS leaf / mTLS | archive.*, jobs.*, webhooks — **not billing** |
|
|
| `staff` | CS / sales / admin | statement, balance.adjust (credits) |
|
|
|
|
A leaf node cannot credit an account. A Zapier hop cannot read a customer statement. A browser cannot `archive.put`.
