name: PR Pipeline — Authorize → Validate → Review → Merge
# TRIGGER IS INTENTIONALLY UNFILTERED — DO NOT RE-ADD A `paths:` FILTER.
#
# This workflow previously carried `paths: ['**.prose.md', 'scripts/**.sh',
# '**.yaml', '**.yml']` on both `push` and `pull_request`. Any PR whose diff
# touched none of those patterns (for example a `deliverables/`-only PR, or a
# `scripts/*.py` / `bin/*` change) therefore produced NO Gitea Actions run at
# all: validation, lint, ai-review and the merge gate were silently skipped.
# Validation must run for every pull request and every push to master, so the
# trigger is deliberately unconditional.
