📝 Walkthrough📝 WalkthroughWalkthroughThe changes introduce a new architectural decision record (ADR) titled "ArNS Cache Timing" that outlines the caching mechanisms for ArNS resolution. It describes the balance between response latency and the freshness of responses through configurable caching levels. The document includes a flowchart detailing the resolution process, cache hit/miss conditions, and defines various caching-related timeouts and limits to aid gateway operators in optimizing their caching strategies.

22-58: Consider enhancing flowchart clarityThe flowchart effectively shows the caching layers, but consider adding:
- Notes linking "Up-to-date" states with their corresponding TTL parameters
- Visual indicators for the debouncing and concurrency limiting mechanisms
Example enhancement for the TTL relationship:
StateStatus -->|Up-to-date (within ANT state TTL)| Resolution([Resolution Returned])
64-65: Fix typo in timeout description-The miminum amount of time +The minimum amount of time
62-71: Consider adding parameter guidanceThe timeout parameters would benefit from:
- Default values or recommended ranges
- Examples of how different values might impact system behavior
- Guidance on tuning these parameters based on gateway operator needs
This would help operators make informed decisions when configuring their gateways.

3-6: Consider adding more context about the decision statusSince this is a proposed ADR, it would be helpful to include:
- Expected timeline for decision
- Prerequisites or dependencies for the decision
- Next steps in the decision process

23-59: Enhance flowchart documentationThe flowchart effectively illustrates the resolution flow, but would benefit from:
- A legend explaining the color coding (pink/blue nodes)
- Documentation about the expected behavior at each decision point
- Explanation of failure scenarios and retry mechanisms
63-74: Add operational context for timeout valuesConsider enhancing the timeout documentation with:
- Rationale behind the default values
- Impact of adjusting these values
- Recommendations for different deployment scenarios (e.g., high-traffic vs. low-traffic gateways)
- Monitoring recommendations for these parameters
1-79: Consider adding security implicationsThe ADR would benefit from a section addressing security considerations:
- Cache poisoning prevention
- DoS protection mechanisms
- Impact of caching on privacy
- Security implications of cache invalidation
