exploderous #33: detailed technical mutation-findings report, retained as reference

Core mutation findings: remediation proposals for maintainer approval

Recommendation: approve focused behavior tests for simultaneous Character contact and the minimum-Footprint upward sweep, plus a fail-fast rewrite of the existing tick-waiting test. Investigate RNG guarantees separately. Consider only the two precisely scoped equivalence candidates below; approve each individually before any exclusion. No production defect in the unmutated core is established by this review.

This is the report-only deliverable for #33, using both #32 and the delivered manual workflow from #34. Nothing has been fixed, excluded, retuned, or rerun. Proposed checks below are future validation plans, not newly executed tests.

1. Evidence, coverage, and interpretation

ZuriHac 2020 hatrace: syscalls to implement

Easy

FS

  • change directory: chdir, fchdir
  • change permissions: chmod, fchmod, fchmodat
  • change ownership: chown, fchown, lchown, fchownat
  • duplicate file descriptors: dup, dup2, dup3
  • create file descriptor for even notifications: eventfd, eventfd2, the latter is used by GHC RTS
  • FS synchronization: fdatasync, fsync, sync, syncfs - could be useful for checking if writes done by a program are durable
