+# Python 3.14 Nixpkgs Compatibility Overrides
+
+Document and implement the `packageOverrides` needed to build authentik's Python dependency tree under `python314` on nixos-25.11.
+
+## Problem
+
+Authentik 2026.2.0 requires Python 3.14 (`requires-python = "==3.14.*"`). The nixos-25.11 channel's `python314` package set has two issues:
+
+1. **`astor` 0.8.1** — test suite uses `ast.Num`, `ast.Str`, and `ast.NameConstant`, which were removed in Python 3.14. Build fails during `pytestCheckPhase`.
+2. **`django` defaults to 4.2.x** — Django 4.2 does not support Python 3.14. The `python314.pkgs.django` attribute points to `django_4` (4.2.28), not `django_5`.
+
+Both failures cascade through the dependency graph, breaking `trio` → `anyio` → `httpcore`/`azure-core`/etc. and ultimately `authentik-django`.
+
+## Research Findings
+
+### astor
+
+Current nixpkgs (unstable/newer 25.11 snapshots) already fixes this:
+
+- Uses an **unstable git snapshot** `df09001112f079db54e7c5358fa143e1e63e74c4` (2024-03-30), not the 0.8.1 release
+- Carries `python314-compat.patch` from upstream PR [#233](https://github.com/berkerpeksag/astor/pull/233)
+- The patch replaces removed `ast.Num`/`ast.Str`/`ast.NameConstant` with `ast.Constant` and guards affected tests with version checks
+- Hash: `sha256-VF+harl/q2yRU2yqN1Txud3YBNSeedQNw2SZNYQFsno=`
+
+Ringtail's nixos-25.11 registry pin predates this fix. Rather than updating the system-wide nixpkgs (which has broader implications), we carry the override in our derivation.
+
+### django
+
+The nixpkgs authentik `package.nix` (2025.12.4) includes `django = final.django_5;` in its `packageOverrides`. This is still needed for 2026.2.0 — `python314` does not default to Django 5.x.
+
+### Dependency chain (astor failure cascade)
+
+```
+astor (test failure)
+├── trio (nativeCheckInputs)
+│   └── anyio
+│       ├── httpcore → httpx → msgraph-sdk, azure-core, ...
+│       └── azure-core → azure-identity, azure-storage-blob
+├── djangoql (runtime dep of authentik)
+└── django 4.2.28 (also broken, separate issue)
+    └── authentik-django (1 dependency failed)
+```
+
+## What to Do
+
+Add these overrides to `authentik-django.nix`'s `packageOverrides` block:
+
+1. **`django = final.django_5;`** — same as nixpkgs authentik does
+2. **`astor`** — override to use the patched git snapshot with the python314-compat.patch, matching what current nixpkgs does (NOT just disabling tests)
+
+The override for astor should use `fetchFromGitHub` with owner `berkerpeksag`, repo `astor`, rev `df09001112f079db54e7c5358fa143e1e63e74c4`, and carry the patch from nixpkgs PR #233. This is a proper fix, not a test skip.
