# Pipeline 2 — Core Validation (target: < 5 min on PR)
#
# Two jobs, gated by a shared path-filter:
#
#   test-pr      — PR trigger only.
#                  Single runner (ubuntu-22.04, pinned Flutter).
#                  Only the packages that changed are tested, so a one-line
#                  fix in hyper_render_html doesn't re-run core/markdown/etc.
#
#   test-matrix  — Push to main/develop only.
#                  Full 3-OS × 2-channel matrix to catch platform regressions
#                  before the tag lands.
#
# What this job does NOT do (handled by Pipeline 1 — analyze.yml):
#   • dart format
#   • flutter analyze
