Replace the entity slugs on organizations, workspaces, resource pools,
and
plan ladders with nullable `key` columns and add keys to products,
prices,
and entitlement sets. Rename `providers.slug` to `provider` and add
partial
unique indexes for system and org role names.
Assign invoice numbers per billing account from a gapless transactional
counter; Stripe's number moves to the invoice mapping as an external
reference.
Seeds, fixtures, and the operator lookup address rows by key, and the
returning-login resync no longer blanks a display name when the IdP
sends
no `name` claim.
Enforce 10j's verified gaps (schema-hardening change):
- Migration 00010: partial unique indexes for one default pool and one
primary assignment per workspace, plus CHECKs pinning
pool/provider/subscription vocabularies and provider lifecycle
timestamps.
- Workspace creation shares a transactional provisioning function;
extension validates its target pool; last-tier deletion of a defaulted
ladder is guarded; signup completes plan-less on a broken ladder.
- Boot asserts integration slug parity and validates declared config
enums; Stripe invoice amounts are range-checked; domain cancellation
runs a final evidence probe; rule authoring is additive-only.
