# Self-license & tier gating

The daemon licenses **itself** via its own licensing scheme — the operator runs a
master Keysat that issues the license this instance validates.

## Always boots — no enforce mode

Enforce mode was **retired**: there is no `KEYSAT_LICENSE_ENFORCE` build flag and
`check_at_boot` (`license_self.rs`) always returns `Ok`. A missing/invalid
self-license logs a warning and the daemon runs at the free **Creator** tier
(`Tier::Unlicensed`, surfaced as "Creator" in the admin UI) with Creator caps —
**5 products, 5 policies per product, 10 active discount codes**. Activating a
license lifts those caps and unlocks `recurring_billing` + `zaprite_payments`.
Treat any "marketplace build refuses to start without a license" wording in code
comments or copy as stale.

## Live entitlements

Tier gates must read **LIVE** entitlements from `licenses.entitlements` (refreshed
hourly by `refresh_self_tier_from_db` in `license_self.rs`), **not** the
entitlements baked into the signed payload at issue time. The signed payload is a
point-in-time snapshot; entitlements can change after issuance.

## Never silently widen a tier

Do **not** expand entitlements in `tier::current()` (e.g. "patron implies pro").
Tried in `0.2.0:41`, reverted in `0.2.0:42`. When an operator is stuck on an
old-scheme self-license, the correct fix is: **re-issue** the license + run the
StartOS "Activate Keysat license" action — the new key overwrites
`/data/keysat-license.txt` and `self_tier` refreshes without a daemon restart.

## Entitlements in flight

`unlimited_merchant_profiles` (Creator = 1 merchant profile, Pro/Patron =
unlimited) still needs adding to the master Keysat's Pro/Patron policies — a data
action on the keysat.xyz admin, no code. See [payments](payments.md).
