Distinguish skipped background coordination from real load results and promote foreground demand without resetting coordination deadlines or loader budgets. Add deterministic SWR/XFetch race regressions and document the resulting semantics. Validation: full offline build, 568 tests passing, core branch coverage 92.05%.

Prepare TierCache 2.0.0 with isolated Redis keyspace v2 and the accumulated cache correctness, recovery, resource-lifecycle, async adapter and observability fixes. Existing 1.x deployments require a drained cold-cache cutover; the release documentation describes migration and rollback.
Release preparation also updates dependency baselines and binds resolved dependency scans to exact publication files. Six-instance Docker testing of the same runtime code completed a 60-minute 6000 RPS run and exercised Sentinel failover, partitions, Redis/source outages and recovery. Sentinel remains eventually consistent and can temporarily restore older cached values after failover.
Validation: run the full CI matrix and nightly release gates for this candidate before publication. Final dependency evidence and Maven Central publication follow after these checks pass.
