+# Tech-Debt Audit — intsoc-transactor — 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:** `LOW`.
+
+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 | `MPL-2.0` |
+| Body classifier | `Palimp-MPL-2.0` |
+| Severity | `ok` |
+
+**Recommended next move:** none for licence.
+
+## 3. Documentation debt
+
+| Field | Value |
+|---|---|
+| README lines | 100 |
+| `docs/` files | 13 |
+| `docs/` LoC | 1413 |
+| CHANGELOG.md | Y |
+| CONTRIBUTING.md | Y |
+| CODE_OF_CONDUCT.md | Y |
+| SECURITY.md | Y |
+| Severity | `LOW` |
+
+**Recommended next move:** `docs/` has only 13 file(s). Aim for ≥10 organised docs (architecture, usage, contributing-guide, troubleshooting, design-decisions). The user's bar for a "heavily-developed and well-organised wiki" is ≥10 files with topical organisation.
