Note

Medium Risk
Changes live validation alerting and the production Jenkins pixel job (release checkout and comparison logic); incorrect tag templates or comparator gaps could hide real failures or still miss edge cases.

Overview
Adds dual live validation: each product is checked against current branch definitions and a release snapshot resolved from the live app version, so alerts focus on failures that still apply to what shipped—not schema drift on main.

The Jenkins Jenkinsfile.params pipeline is consolidated around shared validationConfigs, per-product release tag templates, optional ASANA_PROJECT, and a single checkout stage that runs resolve_release_tag.mjs and checks out refs/tags/{tag} before validateRepo.sh receives an optional fourth release definitions path.

validate_live_pixel.mjs validates each CSV row against HEAD and, when a release dir is present, intersects undocumented and validation-failed results via stable error identities (live_validation_comparator.mjs, formatAjvErrorDetails). HEAD-only or release-only skew (e.g. extra param removed on one side) is suppressed; errors present on both sides remain.

applyNotifyOverride makes NOTIFY_PIXEL_OWNERS=false strip assignees/followers for test runs; release tag resolution and Jenkins wiring are covered by new tests.
