+# Tech-Debt Audit — ipv6-tools — 2026-05-26
+
+**Source:** estate-wide automated scan 2026-05-26.
+**Companion:** [`hyperpolymath/standards` 2026-05-26-estate-*-debt audits](https://github.com/hyperpolymath/standards/tree/main/docs/audits).
+**Combined severity:** `HIGH`.
+
+This file records the *raw findings* — it does not by itself fix the debt. Each section ends with a 'Recommended next move' line; closing the debt is follow-up work.
+
+## 1. Proof debt
+
+No proof-bearing files (`*.v`, `*.lean`, `*.agda`, `*.idr`, `*.idr2`, `*.fst`, `*.dfy`, `*.tla`, `*.ads`, `*.adb`) found in this repo.
+
+**Recommended next move:** none.
+
+## 2. Licence debt
+
+| Field | Value |
+|---|---|
+| LICENSE file | `LICENSE` |
+| SPDX header | `MPL-2.0` |
+| Manifest licence | `NONE` |
+| Body classifier | `Palimp-MPL-2.0` |
+| Severity | `ok` |
+
+**Recommended next move:** none for licence.
+
+## 3. Documentation debt
+
+| Field | Value |
+|---|---|
+| README lines | 17 |
+| `docs/` files | 0 |
+| `docs/` LoC | 0 |
+| CHANGELOG.md | N |
+| CONTRIBUTING.md | Y |
+| CODE_OF_CONDUCT.md | Y |
+| SECURITY.md | Y |
+| Severity | `HIGH` |
+
+**Recommended next move:** expand the stub README (currently 17 lines). Minimum: title, what-it-is in one paragraph, install/usage, link to deeper docs. Use `hyperpolymath/rsr-template-repo` as the reference.
+
+Additionally: **CHANGELOG.md is missing.** 65% of estate repos lack one — adopting a CHANGELOG (or auto-generating via `git-cliff`) is a recommended estate-wide follow-up.
