From 0ab6bc4a733aaeaee9d22da519c11209b968360c Mon Sep 17 00:00:00 2001 From: shankar0123 Date: Tue, 12 May 2026 14:02:04 +0000 Subject: [PATCH] =?UTF-8?q?feat(ci):=20item-1=20complete-path=20config-cov?= =?UTF-8?q?erage=20guard=20(PARTIAL=20=E2=80=94=20sandbox=20could=20not=20?= =?UTF-8?q?verify=20Go=20test)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Shell guard verified working in sandbox: - Green on clean repo: 'OK — every CERTCTL_* env var (194) has at least one non-config-package consumer.' - Red on injected orphan: '::error::Orphan env vars — defined in config.go but no consumer found outside internal/config/' with three remediation paths listed. Go test internal/config/coverage_test.go written but NOT verified — sandbox Go 1.25.9 < go.mod's 1.25.10 requirement; toolchain auto-download fails (disk full). Operator must run `make verify` from workstation before merge. Allowlist scaffold at scripts/ci-guards/complete-path-config-coverage-exceptions.yaml. Every entry requires name + justification + expires fields; expired entries fail the guard. Catches the lying-field bug class — env var defined in config.go that no business-logic code reads. The 2026-04-29 SCEP MustStaple Phase 5.6 gap (domain field shipped, service layer never read profile.MustStaple) is the canonical case this guard would have caught at commit time.
