Package	Description
me.ahoo.cosid	The generator interfaces (IdGenerator and its kinds) and the exceptions a generator throws.

Class	Description
AcquireReason	Which step of the slot choice (05-machine-lease.md §2.1) gave the slot; the store reports it, for observation only.
AcquireResult	The outcome of SlotLeaseStore.acquire(java.lang.String, me.ahoo.cosid.lease.Owner, int, java.time.Duration, java.time.Duration, int, java.util.OptionalInt).
AcquireResult.Acquired	A slot was acquired.
AcquireResult.Acquired.Builder	Builds an AcquireResult.Acquired.
AcquireResult.Exhausted	Every slot below the limit is held.
LeaseKeeper	Holds the slot lease of a runtime (05-machine-lease.md §4.2): acquires it at LeaseKeeper.start(), renews it every ttl/3 with backoff, re-acquires a lost slot and publishes each holding as a SlotBinding.
Owner	Who holds a slot lease (05-machine-lease.md §2).
SlotBinding	One holding of a slot and its time window (05-machine-lease.md §4.1).
SlotHandle	The machine slot of a runtime, shared by its time-based generators (D18, 05-machine-lease.md §4.1).
SlotLease	A lease of a time window (floor, ceiling] on a slot (05-machine-lease.md §2).
SlotLease.Builder	Builds a SlotLease; SlotLease.Builder.build() checks the fields.
SlotLeaseStore	Leases time windows on machine slots, the lease primitive of a store (05-machine-lease.md §2).
StaticSlot	A slot the user keeps unique (manual or StatefulSet ordinal), with a time window from a local file (05-machine-lease.md §4.4): the file holds the ceiling, written ahead and fsynced before use, so a crash followed by a clock regression cannot repeat ids.
