PR Review: "chore: move code"

Summary

Three files changed (+5/-13). Two independent refactors: a timestamp capture fix in ping.rs and a config-computation encapsulation in ping_task.rs.

---

Correctness — ping.rs

The ping.rs change has real behavioral significance beyond what "move code" implies.

FDB transaction closures passed to .run(|tx| async move { ... }) are retried on conflict. Previously, util::timestamp::now() was called inside the closure, so each retry wrote a different timestamp to LastPingTsKey. By capturing now before the closure, the timestamp is stable across retries and correctly represents when the ping measurement was taken, not when the transaction finally committed.

Suggestion: Update the PR description or add a brief comment noting the retry-stability motivation, so future readers understand this is not a purely mechanical move.

---

Encapsulation — ping_task.rs

Moving Duration::from_millis(ctx.config().pegboard().runner_update_ping_interval_ms()) into ping_task::task() is a clean simplification. The config is already accessible via ctx, the call site loses one parameter, and behavior is identical. No concerns.

Convention Checks

Check	Result
Logging (tracing, no eprintln!)	Pass
Concurrency (no Mutex<HashMap>)	Pass
Error handling (anyhow + .context())	Pass
Commit message (conventional commits)	Pass
No docs/limits drift	N/A

---

CI Note

The CI failures visible on this PR (Railway deploys for kitchen-sink, frontend-inspector, ladle) appear to be pre-existing frontend issues unrelated to the Rust changes here.

---

Verdict

Changes are correct and convention-compliant. The one actionable item is clarifying the correctness motivation for the ping.rs timestamp capture in the PR description or a code comment.
