-# Fix ntfy Nix Version
-
-Override the nixpkgs ntfy-sh derivation to build v2.17.0 from the forge mirror, aligning the nix-built container with the Dockerfile version.
-
-## Context
-
-Discovered during [[add-container-version-sync-check]]: the ntfy container has both a Dockerfile and a `default.nix`. The Dockerfile builds v2.17.0 from `forge.ops.eblu.me/mirrors/ntfy.git`, but the nix derivation uses `pkgs.ntfy-sh` from nixpkgs which is pinned at 2.15.0. The version sync check currently excludes ntfy from nix version validation as a workaround.
-
-## What Was Done
-
-Replaced the nixpkgs `pkgs.ntfy-sh` reference in `containers/ntfy/default.nix` with a custom derivation that builds v2.17.0 from the forge mirror using `fetchgit`, `buildNpmPackage` (web UI), and `buildGoModule` (server). Docs are skipped (placeholder for `go:embed`, matching the Dockerfile approach).
-
-The `container-version-check` script was updated to extract versions from local nix files via regex (`version = "X.Y.Z"`) before falling back to the Dagger `nix-version` function for unmodified nixpkgs packages. This avoids the issue where `nix eval nixpkgs#ntfy-sh.version` returns the upstream 2.15.0 instead of our overridden 2.17.0.

-| `containers/ntfy/default.nix` | Custom derivation building v2.17.0 from forge |
-| `mise-tasks/container-version-check` | Regex-based local nix version extraction |
-
-## Verification
-
-- [x] `dagger call build-nix --src=. --container-name=ntfy` produces a working image
-- [x] Version extractable from local `default.nix` via regex (2.17.0)
-- [x] `mise run container-version-check --all-files` passes with ntfy included
