🤖 Kimi Code Review

This PR only contains documentation changes (README.md updates). No code changes were provided for review.

The changes are:

• Updates devnet version references from pq-devnet-2 to pq-devnet-3 (now current) and pq-devnet-3 to pq-devnet-4 (in development)
• Updates the roadmap section with new priorities including devnet-4 support, spawned P2P event loop, state pruning, and ZK proving

These are purely documentation updates with no security, correctness, or performance implications. The changes appear accurate and consistent.

🤖 Codex Code Review

No findings affecting correctness, security, performance, or consensus behavior.

• This PR only updates documentation in README.md (not runtime Rust/consensus code), so there is no direct impact on fork choice, attestation validation, justification/finalization, STF, XMSS verification, or SSZ handling.
• The updated devnet sections at README.md:89, README.md:93, and README.md:99 are internally consistent.

Residual risk/testing gap:

• No code paths changed, so there’s nothing to test at runtime; only risk is documentation drift if devnet status changes again.

Review: docs: update roadmap and devnet sections

Scope: Documentation-only changes to README.md (+9/-8 lines). No code, logic, or configuration changes.

Summary

The PR advances the devnet versioning narrative:

• Promotes pq-devnet-3 from "in progress" to "running"
• Introduces pq-devnet-4 as the new in-progress target
• Adds devnet3 to the older devnets example list
• Updates the roadmap to reflect current priorities

Observations

Correctness:

• The devnet progression (devnet-3 now active, devnet-4 in progress) is internally consistent throughout the diff.
• The "Older devnets" example list is correctly updated to include devnet3.

Wording consistency:

• The pq-devnet-3 section now reads "We are running the ... spec" while pq-devnet-4 reads "We are working on adding support for..." — this asymmetry is intentional and appropriate.
• The Docker tag note for devnet-3 drops the future tense ("will be published") and uses present tense ("is available"), which is correct.

Roadmap hygiene:

• Three completed/superseded issues (73, 91, 78) are removed and replaced with four new ones (155, 165, 166, 156). The new issue links look well-scoped and correctly ordered by priority as described.
• Issue 103 (non-finalization hardening) and 76/75 are retained — appropriate since those are still open.

Minor nit:

• The pq-devnet-3 section no longer mentions a deprecation notice / timeline for when it moves to "older devnets", unlike the original pq-devnet-2 section which said "Support... will be ending soon". This is probably fine since the deprecation lifecycle is covered by the "Older devnets" paragraph, but adding a brief note about when devnet-3 support ends (i.e., once devnet-4 ships) could improve clarity for external readers.

Verdict

Changes are accurate, internally consistent, and appropriately scoped. The minor nit above is optional. Ready to merge.
