+
+## Git Commit Policy
+
+> Concise rules for this repository.
+> Details: <https://www.conventionalcommits.org/>
+### Format
+
+```txt
+<type>: <subject>
+<body>
+<footer>
+```
+
+* **type**: use one of:
+
+  * `feat` — new feature or change in behaviour (e.g., `feat: add new feature`)
+  * `fix` — bug fix (e.g., `fix: correct validation logic`)
+  * `perf` — performance improvement, no behaviour change (e.g., `perf: improve
+    response time`)
+  * `refactor` — internal code change, no behaviour change. Includes
+    formatting-only changes. (e.g., `refactor: reorganise module structure`)
+  * `test` — adding missing tests or correcting existing tests (e.g., `test: add
+    smoke test`)
+  * `docs` — documentation (e.g., `docs: update guide`)
+  * `ci` — CI configuration/jobs (e.g., `ci: increase job timeout`)
+  * `build` — build system or artefacts (e.g., `build: update dockerfile`)
+  * `chore` — maintenance (e.g., `chore: update dependencies`)
+  * `revert` — revert (e.g., `revert: rollback previous change`)
+* **subject**: imperative, no full stop, does not start with a capital letter,
+  **≤ 50 characters (including type)**
+* **body**: wrap at **72 characters**; explain **what & why** (not how)
+* **footer**: optional notes
+
+### Commit template
+
+A commit template with 50/72 visual guides is provided in
+[.gitcommit](/.gitcommit). Set it with:
+
+```sh
+git config commit.template .gitcommit
+```
