parallel_tests Railspike debug log

2026-11-04 — one-shot closeout

Necessary/useful instructions

• Shared verification rule ("a focused check does not establish a full-suite pass"): kept the record honest that the first full parallel run is still the maintainer's, even after two clean stress runs. Retain.

• "Record … discoveries": captured that test history had no durations, contradicting an earlier Step 1 claim, so the superseded plan is not trusted on that point later. Retain.

Redundant/unnecessary instructions

• No supported findings.

Inapplicable instructions

• Extended estimates per alternative/stage: none exist in this cycle.

Uncertain assessments

• The host's standing "agents don't run the full suite" rule and Railspike's "replay the reported condition" guidance pull in different directions for runner changes, whose real check is a full run. The record resolves it by deferring to the maintainer; a host note on how to verify test-infrastructure changes might help.
