+# Retired Scripts
+
+The `scripts/` directory previously contained one-shot authoring helpers
+that were used to bootstrap the initial 16 modules and 379 topics. Those
+scripts have been retired (issue #6) and removed because:
+
+- They referenced internal generation contexts that no longer apply.
+- None were imported by other scripts, workflows, or Makefile targets.
+- They are not maintained tools — re-running them would not reproduce
+  current content.
+
+## What was retired
+
+The following scripts were removed in the chore PR that closed #6:
+
+- `complete_module_content.py`
+- `complete_module_readmes.py`
+- `fix_remaining_placeholders.py`
+- `generate_modulo_14.py`
+- `generate_modulo_16.py`
+- `generate_patrones.py`
+- `populate_content.py`
+- `update_readmes.py`
+- `update_references.py`
+
+If you need to look at what they did, fetch the parent SHA of the chore
+PR's first commit from git history.
+
+## Canonical authoring flow today
+
+To author or extend a topic, follow the workflow in `AGENTS.md` and
+`docs/CHARTER.md`. The maintained tools in `scripts/` are:
+
+- `progress.py` — read-only progress tracking
+- `generate_structure.py` — create a new module/topic skeleton
+- `validate_all_modules.py` — module structure validator (CI gate)
+- `validate_ci_gate.py` — gold-quality validator
+- `link_check.py` — external-link verification
