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.

- NewV7FromReader
- Created
- 2026-08-19T02:48:25Z
Contract
- uuid.NewV7FromReader generates valid UUID v7 with crypto/rand.Reader
- uuid.NewV7FromReader returns UUID with Version 7 and RFC4122 variant
- uuid.NewV7FromReader generates deterministic UUID v7 using custom byte reader with version and variant bits applied
- uuid.NewV7FromReader returns error and Nil UUID when reader returns EOF or error
- uuid.NewV7FromReader generates time-ordered UUIDs with monotonic sequence ordering
- uuid.Validate and uuid.Parse confirm validity of UUID v7 generated by uuid.NewV7FromReader
