StellaOps.Audit.ReplayToken

Deterministic replay token generation used to make triage decisions and scoring reproducible and audit-ready.

Token format

v1 (no expiration):

replay:v1.0:<algorithm>:<sha256_hex>

Example:

replay:v1.0:SHA-256:0123abcd...

v2 (includes expiration):

replay:v2.0:<algorithm>:<sha256_hex>:<expires_unix_seconds>

Create a ReplayTokenRequest with feed/rules/policy/input digests.
Call IReplayTokenGenerator.Generate(request) to get a stable token value.
Store the token's Canonical string alongside immutable decision events.
ReplayToken.Parse uses DateTimeOffset.UnixEpoch for GeneratedAt because the canonical format does not include generation time.
