Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

HOW- Goal
- create and manage a generic resource pool with puddle.NewPool
- Packages
- Created
- 2026-08-21T00:44:46Z
Contract
- puddle.NewPool initializes a type-parameterized resource pool with constructor and MaxSize config
- pool.Acquire creates and leases a resource handle whose Value is accessible and increments AcquiredResources
- resource.Release returns the resource to the pool making it available as an idle resource
- resource.Destroy removes the resource from the pool invoking the Destructor callback
- pool.Close closes the pool and causes subsequent Acquire calls to return ErrClosedPool
