"""Satori Release Builder & Per-Agent Skill Mirror Synchronizer (scripts/build_release.py): v6.5.4.

1. Reads `version` dynamically from `package.json`.
2. Cleans up any stale v6.5.1 or older zip archives from `dist/`.
3. Syncs canonical root `SKILL.md` byte-for-byte into the Category B per-agent
   skill mirror paths (.agents, .cursor, .opencode, .hermes).
4. Updates the SHA-256 integrity digest of `references/SOUL.md` in `openclaw.plugin.json`.
5. Normalizes all line endings to LF (`\n`) for cross-platform archive determinism.
6. Builds clean Claude.ai web-uploadable zip archives:
   - `dist/SatoriSkill-Full-v{version}.zip`: Complete Full edition with all reference shards
   - `dist/SatoriSkill-Compact-v{version}.zip`: Self-contained Compact edition (<=7,800 chars)
   - `dist/SatoriSkill-v{version}.zip`: Backward-compatible alias for automated tools
7. Generates `dist/SHA256SUMS.txt` with SHA-256 digests of all built archives.
8. Runs clean-room upgrade and uninstall verification test (Metric 30), writing `evals/upgrade_test_report.json`.
9. Executes `scripts/validate_skill.py` to ensure all verification checks pass before finishing.
