Your included PR review attempts over the past 7 days set your current allowance at 10 reviews per hour. 📝 WalkthroughWalkthroughThe change centralizes report metadata parsing, profile file loading, Blob storage operations, compressed artifact publishing, and daily pointer writes. AWFY, benchmark, JetStream, Test262, and Web Tooling publishers now use the shared utilities. Tests cover fallbacks, attachments, read errors, and upload failures. ChangesReport publication
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: ⚪ Minimal · up to This change centralizes report-publication helpers and adds timestamp-range validation. No unresolved issue indicates a current risk to report publishing or users. Sequence Diagram(s)sequenceDiagram

Suite TimingTest Runner (interpreted: 12,818 passed; bytecode: 12,818 passed)
MemoryGC rows aggregate the main thread plus all worker thread-local GCs. Test runner worker shutdown frees thread-local heaps in bulk; that shutdown reclamation is not counted as GC collections or collected objects.
Benchmarks (interpreted: 440; bytecode: 440)
MemoryGC rows aggregate the main thread plus all worker thread-local GCs. Benchmark runner performs explicit between-file collections, so collection and collected-object counts can be much higher than the test runner.

- Line 20: Update the Unix-seconds conversion in the timestamp helper to detect
dates outside the valid Date range and return null instead of allowing
toISOString() to throw RangeError. Preserve valid timestamp conversion so
currentRunMetadata can use its fallback when conversion fails.

89c3b7e61873fb92867e1554c4d821324bc9b16bpassed all 49 checks, including the full interpreter and bytecode suites, native/CLI checks, test262, benchmark guards, and website checks../format.pas --check: 463 files pass.The timestamp parser now returns
nullfor positive integer timestamps outside JavaScript’s Date range, preserving the existing fallback instead of throwing. Boundary coverage accepts the inclusive maximum and rejects larger safe integers; the real profile publisher CLI verifies fallback behavior. The full website suite, TypeScript, Biome (127 files), formatter (463 files), and ordinary hooks passed again for89c3b7e61873fb92867e1554c4d821324bc9b16b; all 49 independent CI checks also passed on this updated head.A separate manual diff review checked storage paths, access selection, timestamp semantics, upload ordering, report-specific validators, and unchanged history retrieval. Live Blob publication and a production website deployment were not performed.
Follow-up #1232 depends on this PR and targets
codex/audit-report-publishing, keeping its history retrieval and snapshot changes in a separate review.
