From 8c1c02e0e608a604d64f2107ce9c81d197635279 Mon Sep 17 00:00:00 2001 From: jedarden Date: Fri, 22 May 2026 23:57:23 -0400 Subject: [PATCH] feat(pdftract-1wfp): implement SHA256SUMS aggregate file generation Add compute-sha256sums step to pdftract-ci publish-if-tag that produces an aggregate SHA256SUMS file covering all distributed artifacts: binary archives, Python wheels, sdist, and CycloneDX SBOM. Key changes: - Glob-based artifact collection (tar.gz, zip, whl, cdx.json) - Deterministic sorting with LC_ALL=C sort -k 2 for reproducibility - Local verification via sha256sum --check before publishing - Dynamic artifact upload array instead of hardcoded EXPECTED_ARTIFACTS - SBOM added as optional input artifact The SHA256SUMS file format matches GNU coreutils sha256sum output, enabling one-command verification with cosign verify-blob.
