v1.8.9 — Replay Determinism & Observable Outcome Validation

EdgeNetSwitch v1.8.9

v1.8.9 adds replay-verifiable determinism to the runtime.

This release introduces:

• ReplayRecorder and ReplayPlayer
• ReplayOutcome and ReplayOutcomeCollector
• Replay equivalence validation based on observable terminal history
• Lifecycle-keyed deterministic failure replay

Replay validation now verifies:

• terminal event ordering
• lifecycle ordering
• drop attribution
• deterministic failure reproducibility

Replay records remain ingress-only. Terminal outcomes are regenerated by the runtime and compared against the original execution history.

The test suite now covers replay equivalence, deterministic failure replay, and lifecycle-aware observable outcome validation.
