Strix Security ReviewNo security issues found. Review summaryReviewed all six changed files: the new request-correlated diagnostics helper, its inclusion in the Railway services watch list, the failure-message and post-publication logging changes in seed-natural-events.mjs, and the three test files. The change is privacy-conscious and introduces no security issues. The diagnostics helper records only primitive counters (wire byte counts, timing deltas, boolean readiness flags, request count) and never request/response content, URLs or query strings, headers, or addresses. The error-message and console.warn interpolations are limited to hardcoded source names (eonet, gdacs:, nhc), allowlist-filtered error name/code/syscall fields, a boolean IP-family flag, and internal health timestamps/status/record counts — no secrets, tokens, or untrusted input reach these sinks. Source and URL values are hardcoded or config-derived, not attacker-controlled, and no new endpoints or authorization paths are introduced. The added tests explicitly assert that response content, tokens, and local addresses are not logged. Static analysis (semgrep, 68 rules) reported zero findings on the changed source files.

undici:request:bodyChunkReceived listener so missing body-chunk events do not
report wireBodyBytes as zero or produce misleading byte timings; use a transport
that publishes the event or represent measurements as unknown when telemetry is
unavailable, preserving zero only when the transport confirms no bytes arrived.

- Line 40: Update the byte-count assertions for complete, partial, gzip, and
redirected responses to accept unknown measurements when telemetry is
unavailable, while retaining exact-byte checks when a value is reported;
alternatively, use a transport that emits the required Undici event for those
checks.

Summary
Natural-event source timeouts currently report the request/body phase but cannot show whether a request was sent locally, whether body bytes arrived, or whether the HTTP body completed. Add passive, request-correlated Undici measurements to existing failure messages, plus failed-source last-success and remaining-retention context after publication.
Counters cover the latest redirect hop and encoded payload bytes. A local send observation does not prove remote receipt; HTTP completion does not prove valid JSON. Unobserved transports remain explicitly unknown. Successful attempts emit no new diagnostics; retries, deadlines, dispatchers, payloads and freshness metadata remain unchanged. Include the helper in the climate bundle deployment watch list.
Verification
git diff --checkand commit Unicode check passed.Local tests use Node 24.20.0. Production Node 24.10.0 / bundled Undici 7.16.0 hook compatibility was checked against upstream source, but this change has not been deployed or accepted through a natural production run. It improves failure evidence; it does not claim to prevent upstream outages. No UI or public API contract changes.

Review follow-up
Body byte counts now remain
nulluntil a chunk event is observed. Request/header/completion hooks alone do not establish byte telemetry support. A regression test reproduces the missing-hook case; native transfer tests still verify measured byte counts.Summary by CodeRabbit
