SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill addresses the critical need to ensure that game replays remain consistent and accurate across code changes, schema updates, and gameplay modifications, preventing regressions and maintaining data integrity.

Core Features & Use Cases

Deterministic Replay Validation: Verifies that replays produce identical authoritative results when executed multiple times under the same conditions.
Cross-Version Compatibility: Ensures that replay fixtures from older versions can still be validated against current game states after schema migrations.
Divergence Isolation: Helps pinpoint the exact action or tick where replay data begins to diverge, simplifying debugging.
Use Case: After updating the networking code for a multiplayer game, use this Skill to re-run existing replay fixtures and confirm that the new code doesn't introduce desynchronization issues.

Quick Start

Use the replay-validation-workflow skill to validate replay integrity for the 'multiplayer-lobby-scenario' fixture.

FAQPage Schema

How do I validate deterministic replay integrity after a schema migration?▼

Validating deterministic replay integrity after schema migrations requires re-running existing replay fixtures against current game states to verify they produce identical authoritative results and isolate any divergence points to specific action or tick boundaries.

What is deterministic replay validation and when do I need it?▼

Deterministic replay validation verifies that replays produce identical authoritative results when executed multiple times under the same conditions. You need it after updating networking code, gameplay logic, or event-log loaders to prevent desynchronization regressions.

How do I isolate the exact tick where my gameplay replay starts to diverge?▼

Isolating the exact tick where gameplay replay diverges involves comparing deterministic boundaries across replay fixtures and validating them against identical authoritative results to pinpoint the specific action or tick boundary where divergence begins.

Can I use replay validation to check cross-version compatibility for older game state fixtures?▼

Yes, replay validation ensures that replay fixtures from older versions can still be validated against current game states after schema migrations by comparing deterministic boundaries and verifying identical authoritative results across code changes.

Why does my multiplayer replay desynchronize after updating networking code?▼

Multiplayer replay desynchronization after networking code updates occurs when new code introduces non-deterministic state transitions. Re-run existing replay fixtures through a validation workflow to compare authoritative results and isolate divergence to specific action boundaries.

What's the best way to test replay event-log modifications for deterministic consistency?▼

The best way to test replay event-log modifications for deterministic consistency is applying a validation workflow that compares deterministic boundaries, validates against identical authoritative results, and isolates divergence points to specific action or tick boundaries.
