I/O-free statistics, budget policy, and host mismatch logic for perfgate
Documentation

perfgate-domain

Pure, I/O-free policy and statistics logic for perfgate.

Responsibilities

  • Computes summary statistics from samples (median, min, max).
  • Compares baseline vs current stats against metric budgets.
  • Produces per-metric deltas and verdicts (pass/warn/fail).
  • Derives structured findings/reports from compare receipts.
  • Detects host mismatch signals between baseline and current runs.
  • Provides paired-benchmark math (compute_paired_stats, compare_paired_stats).

Boundaries

  • No process spawning.
  • No filesystem or network I/O.
  • No CLI parsing or formatting concerns.

Why This Layer Exists

The crate is intentionally pure so it stays easy to test, deterministic, and reusable from both CLI and higher-level orchestration code.

Workspace Role

perfgate-domain sits above perfgate-types and below perfgate-app:

perfgate-types -> perfgate-domain -> perfgate-app
