From b5140e6ff24a8c95c71c998ead0cfc0cc243fe6d Mon Sep 17 00:00:00 2001 From: "Jonathan D.A. Jewell" <6759885+hyperpolymath@users.noreply.github.com> Date: Sun, 17 May 2026 06:50:21 +0100 Subject: [PATCH 1/6] fix(reconcile): --verify no longer crashes on JSON-encoding its result MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ScorecardReconciler.verify/2 returns {:ok, summary} | {:error, reason} whereas reconcile/3 returns a bare map. The mix task fed the raw result straight to Jason.encode!/2, which cannot encode a tuple, so `mix hypatia.reconcile owner/repo --verify` crashed on output (the verify logic itself ran correctly — recurrence_defects were computed, just never printed). Surfaced by the live modshells reconcile run while closing the Scorecard epic (hypatia#260). Normalise verify to a bare map at the task boundary (matching reconcile/3's convention): {:ok, summary} -> summary; {:error, reason} -> %{repo, verified: false, error: reason}. Both the success and the no-token error path now emit clean JSON. Task-wrapper only; no change to verify/2 or any tested code path; reconciler suite green. Refs #260 #263.

Pre-existing on main; fixed here so #272 can clear governance / Security policy checks. The Language/anti-pattern (Python) red was a stale run against the pre-escape governance-reusable; the bench scripts already carry both .hypatia-ignore entries and inline hypatia:ignore pragmas, so it resolves on re-run against current standards/main.

Behaviour verified across advisory / regression / no-regression / empty-input / usage-error cases. - tests.yml + benchmarks/README.md rewired to 'cargo run --manifest-path'. - Removed the now-moot exemptions: .hypatia-ignore lines, .hypatia-exemptions.md rows, and the stale .hypatia-baseline.json banned_language_file entries — so the carve-out can't become drift. Unblocks #272's governance / Language anti-pattern by eliminating the Python rather than suppressing it.
