+# Global Regex and ReDoS Policy
+
+Whenever you are writing, modifying, or reviewing Regular Expressions (Regex) in this codebase, you **MUST** adhere to the project's structural-extraction accuracy and ReDoS immunity standards.
+
+1. **ReDoS Immunity & Boundary Correctness**: You must read and follow the 12 engine rules defined in `gitgalaxy/standards/how_to_add_a_language.md`. 
+2. **Hardening Process**: You must follow the 5-stage pipeline checklist and avoid the recurring bug classes outlined in `tests/extraction/how_to_harden_extraction.md`.
+3. **Use the Tooling**: Always verify regex empirically against the real compiled regex using `tests/extraction/tools/verify_candidates.py` and run the scaling checks. Do not guess whether a payload matches or scales.
+4. **Skills**: If you are deepening or fixing a language's structural-extraction accuracy (e.g. `func_start`, `args`), you must activate and follow the `harden-language-extraction` skill.
+
+# Core Engine Modification CI Checklist
+
+When you are preparing to push a fix or open a PR that touches GitGalaxy's core parsing logic (`language_standards.py`, `detector.py`, `prism.py`), you **MUST** ensure the CI validation gauntlet is handled.
+
+1. **Invoke the ci-push-checklist skill**: You must activate and follow the `.claude/skills/ci-push-checklist/SKILL.md` before pushing to ensure all Golden Masters, Tri-Comparison, and Tree-Sitter baselines are accurately regenerated and validated.

+### Description
+<!-- Describe your changes in detail -->
+
+### Core Engine Modification Checklist
+If your PR changes the core parsing engine (`language_standards.py`, `detector.py`, `prism.py`), you **MUST** complete the following validation gauntlet before merging:
+
+- [ ] **Golden Master Verification**: Ran `crucible_check.py` to verify diffs, and ran `crucible_check.py --update --yes` if the baseline changed due to intentional parsing improvements.
+- [ ] **Tri-Comparison Audit**: Handled by CI automatically, but you should run `python tests/tools/tri_comparison_chart.py --all --ci` locally first. If you intentionally improved precision, regenerate the baseline: `python tests/tools/tri_comparison_chart.py --regenerate --languages <lang>`.
+- [ ] **Tree-Sitter Accuracy**: Ran `python tests/tools/tree_sitter_accuracy_audit.py --ci --all`. If ground truth drifted for valid reasons, regenerated the baseline with `python tests/tools/tree_sitter_accuracy_audit.py --regenerate --lang <lang>`.
+
+> **Note for AI Agents**: If you are an AI agent generating this PR, you MUST invoke the `ci-push-checklist` skill to ensure these steps are completed properly.

+## 🔒 CI Pipeline & Baselines
 
-`tests/golden_master_audit.json` and `tests/golden_master_zero_dep_audit.json` are the accepted-good snapshots that every PR's output is diffed against (see the `crucible-audit` check). A failing diff means GitGalaxy's output changed -- that's either a bug you should fix, or an intentional improvement whose new baseline needs to be deliberately re-blessed.
+When you modify GitGalaxy's core engine, several CI workflows will rigorously test your changes against established baselines. If your changes intentionally improve parsing precision, you must regenerate the corresponding baselines.
 
-**Never** hand-copy fresh output over these files. Always use:
+1. **Golden Crucible Baselines (`tests/golden_master_audit.json`)**
+   This validates exact extraction output.
+   - Run `python tests/tools/crucible_check.py` to view structural drift.
+   - To re-bless the new state: `python tests/tools/crucible_check.py --update --yes`
 
-```
-python tests/tools/update_golden_master.py
-```
+2. **Tri-Comparison Ledger (`docs/self_scan/tri_comparison_ledger.json`)**
+   This compares GitGalaxy precision against ctags and tree-sitter.
+   - Run `python tests/tools/tri_comparison_chart.py --all --ci` to test.
+   - If you improved precision, lock it in: `python tests/tools/tri_comparison_chart.py --regenerate --languages <lang>`
+
+3. **Tree-Sitter Accuracy (`docs/self_scan/tree_sitter_accuracy_history.csv`)**
+   This audits AST accuracy against tree-sitter ground truth. 
+   - Run `python tests/tools/tree_sitter_accuracy_audit.py --ci --all`.
+   - If your regex fix legitimately drops false positives causing ground truth drift, regenerate the baseline: `python tests/tools/tree_sitter_accuracy_audit.py --regenerate --lang <lang>`
 
-It shows you exactly what's about to change before writing anything, and requires explicit confirmation. If your PR touches either fixture, **explain why in the PR description** (e.g. "improved the Rust parser, now correctly detects async trait bounds") -- a CI check flags any PR that modifies these files so it's never invisible in a large diff.
