+# ntfy Notification Module Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add a `my.profiles.ntfy` NixOS module that runs an auth-required self-hosted ntfy server on jupiter, exposes a homepage tile, and wires a Home Assistant `rest_command` for publishing notifications.
+
+**Architecture:** A single profile module under `modules/environments/ntfy/`, following the repo's `my.profiles.<name>` pattern. It configures `services.ntfy-sh` with `auth-default-access = deny-all`, opens the firewall, registers a homepage tile, and — when the home-assistant profile is enabled — merges a `rest_command.ntfy_send` into `services.home-assistant.config`. No secrets touch the Nix store; credentials are provisioned manually by the operator, and the only secret lives in HA's `secrets.yaml`.
+
+**Tech Stack:** Nix (flake-parts NixOS config), nixpkgs `services.ntfy-sh`, `services.home-assistant`, nixfmt-rfc-style.
+
+## Global Constraints
+
+- Follow the profile pattern exactly: `let cfg = config.my.profiles.<name>; in { options.my.profiles.<name>.enable = lib.mkEnableOption "..."; config = lib.mkIf cfg.enable { ... }; }`.
+- Namespace is `my.profiles.ntfy`.
+- Homepage self-registration uses `my.homepage.services` (list of `{ group; name; description; href; icon; }`).
+- `hostName` is bound from `config.networking.hostName`, matching sibling modules.
+- All `.nix` files must be formatted with `nixfmt-rfc-style`.
+- No secret values may appear in any `.nix` file (nothing enters the Nix store). The only secret is `ntfy_password` in `/var/lib/hass/secrets.yaml`, provisioned by hand.
+- Evaluation check used throughout (runs on darwin without a Linux builder):
+  `nix eval '.#nixosConfigurations.jupiter.config.system.build.toplevel.drvPath'`
+- Do NOT run `nixos-rebuild` or SSH to jupiter; deploy + provisioning are operator steps the user runs on the host.
+
+---
+
+### Task 1: Create the ntfy server module (server + homepage tile)
+
+**Files:**
+- Create: `modules/environments/ntfy/default.nix`
+- Modify: `modules/environments/default.nix` (add `./ntfy` to `imports`)
+- Modify: `machines/jupiter/environments.nix` (enable the profile)
+
+**Interfaces:**
+- Consumes: `config.networking.hostName`; `services.ntfy-sh` (nixpkgs); `my.homepage.services` (repo homepage module).
+- Produces: option `my.profiles.ntfy.enable` (bool), `my.profiles.ntfy.port` (port, default 2586), `my.profiles.ntfy.topic` (str, default "ha"), `my.profiles.ntfy.haIntegration.enable` (bool, default true). Later tasks rely on `cfg.port`, `cfg.topic`, and `cfg.haIntegration.enable`.
+
+- [ ] **Step 1: Create the module file**
+
+Create `modules/environments/ntfy/default.nix`:
+
+```nix
+# self-hosted push notification server (ntfy)
+{
+  config,
+  lib,
+  ...
+}:
+let
+  cfg = config.my.profiles.ntfy;
+  hostName = config.networking.hostName;
+in
+{
+  options.my.profiles.ntfy = with lib; {
+    enable = mkEnableOption "ntfy notification server";
+
+    port = mkOption {
+      type = types.port;
+      default = 2586;
+      description = "HTTP port ntfy listens on.";
+    };
+
+    topic = mkOption {
+      type = types.str;
+      default = "ha";
+      description = "Topic Home Assistant publishes notifications to.";
+    };
+
+    haIntegration.enable = mkOption {
+      type = types.bool;
+      default = true;
+      description = "Wire a Home Assistant rest_command that publishes to ntfy.";
+    };
+  };
+
+  config = lib.mkIf cfg.enable {
+    services.ntfy-sh = {
+      enable = true;
+      settings = {
+        base-url = "http://${hostName}:${toString cfg.port}";
+        listen-http = ":${toString cfg.port}";
+        auth-file = "/var/lib/ntfy-sh/user.db";
+        auth-default-access = "deny-all";
+      };
+    };
+
+    networking.firewall.allowedTCPPorts = [ cfg.port ];
+
+    my.homepage.services = [
+      {
+        group = "Services";
+        name = "ntfy";
+        description = "Push notifications";
+        href = "http://${hostName}:${toString cfg.port}";
+        icon = "ntfy.svg";
+      }
+    ];
+  };
+}
+```
+
+- [ ] **Step 2: Register the module in the environments import list**
+
+In `modules/environments/default.nix`, add `./ntfy` to the `imports` list (place it near the other service modules, e.g. after `./home-assistant`):
+
+```nix
+    ./home-assistant
+    ./ntfy
+```
+
+- [ ] **Step 3: Enable the profile on jupiter**
+
+In `machines/jupiter/environments.nix`, inside the `my.profiles = { ... }` block, add:
+
+```nix
+    ntfy.enable = true;
+```
+
+- [ ] **Step 4: Format the new file**
+
+Run: `nixfmt-rfc-style modules/environments/ntfy/default.nix`
+Expected: exits 0, no diff on re-run.
+
+- [ ] **Step 5: Evaluate the configuration**
+
+Run: `nix eval '.#nixosConfigurations.jupiter.config.system.build.toplevel.drvPath'`
+Expected: prints a `/nix/store/...-nixos-system-jupiter-*.drv` path with no evaluation errors. (This forces full module-system evaluation, catching option/type mistakes, without building a Linux derivation.)
+
+- [ ] **Step 6: Confirm the ntfy settings evaluate as expected**
+
+Run: `nix eval --json '.#nixosConfigurations.jupiter.config.services.ntfy-sh.settings'`
+Expected JSON includes `"auth-default-access":"deny-all"`, `"listen-http":":2586"`, and `"base-url":"http://jupiter:2586"`.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add modules/environments/ntfy/default.nix modules/environments/default.nix machines/jupiter/environments.nix
+git commit -m "feat(ntfy): add self-hosted notification server module
+

+```
+
+---
+
+### Task 2: Wire the Home Assistant rest_command
+
+**Files:**
+- Modify: `modules/environments/ntfy/default.nix` (add HA integration block)
+
+**Interfaces:**
+- Consumes: `cfg.port`, `cfg.topic`, `cfg.haIntegration.enable` (Task 1); `config.my.profiles.home-assistant.enable`; `services.home-assistant.config` (nixpkgs / repo home-assistant module).
+- Produces: `services.home-assistant.config.rest_command.ntfy_send`, callable from HA automations as `service: rest_command.ntfy_send`.
+
+- [ ] **Step 1: Add the HA integration block to the module**
+
+The module currently has a single `config = lib.mkIf cfg.enable { ... };`. Change it to merge two conditional configs with `lib.mkMerge` so the HA wiring is gated independently. Replace the `config = lib.mkIf cfg.enable { ... };` assignment with:
+
+```nix
+  config = lib.mkMerge [
+    (lib.mkIf cfg.enable {
+      services.ntfy-sh = {
+        enable = true;
+        settings = {
+          base-url = "http://${hostName}:${toString cfg.port}";
+          listen-http = ":${toString cfg.port}";
+          auth-file = "/var/lib/ntfy-sh/user.db";
+          auth-default-access = "deny-all";
+        };
+      };
+
+      networking.firewall.allowedTCPPorts = [ cfg.port ];
+
+      my.homepage.services = [
+        {
+          group = "Services";
+          name = "ntfy";
+          description = "Push notifications";
+          href = "http://${hostName}:${toString cfg.port}";
+          icon = "ntfy.svg";
+        }
+      ];
+    })
+
+    (lib.mkIf (cfg.enable && cfg.haIntegration.enable && config.my.profiles.home-assistant.enable) {
+      services.home-assistant.config.rest_command.ntfy_send = {
+        url = "http://${hostName}:${toString cfg.port}/${cfg.topic}";
+        method = "POST";
+        payload = "{{ message }}";
+        content_type = "text/plain";
+        username = "homeassistant";
+        password = "!secret ntfy_password";
+        headers = {
+          Title = "{{ title | default('Home Assistant') }}";
+          Priority = "{{ priority | default('default') }}";
+        };
+      };
+    })
+  ];
+```
+
+(The first `mkIf cfg.enable` block is identical to Task 1's config body — it is repeated here because the whole `config` assignment is being replaced with the `mkMerge` form.)
+
+- [ ] **Step 2: Format the file**
+
+Run: `nixfmt-rfc-style modules/environments/ntfy/default.nix`
+Expected: exits 0, no diff on re-run.
+
+- [ ] **Step 3: Evaluate the configuration**
+
+Run: `nix eval '.#nixosConfigurations.jupiter.config.system.build.toplevel.drvPath'`
+Expected: prints a `.drv` path, no evaluation errors (confirms the `rest_command` merges cleanly into the HA config the home-assistant module already defines).
+
+- [ ] **Step 4: Confirm the rest_command evaluated into HA config**
+
+Run: `nix eval --json '.#nixosConfigurations.jupiter.config.services.home-assistant.config.rest_command.ntfy_send'`
+Expected JSON includes `"url":"http://jupiter:2586/ha"`, `"username":"homeassistant"`, and `"password":"!secret ntfy_password"`.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add modules/environments/ntfy/default.nix
+git commit -m "feat(ntfy): wire Home Assistant rest_command publisher

+```
+
+---
+
+## Operator steps (run by the user on jupiter — not part of the agent's task loop)
+
+These require the host and manual credentials, so they are performed by the user after the branch is merged/deployed:
+
+1. Deploy: `sudo nixos-rebuild switch --flake '.#jupiter'`
+2. Create ntfy users:
+   ```bash
+   ntfy user add homeassistant            # set a password
+   ntfy access homeassistant ha write-only
+   ntfy user add --role=admin admin
+   ```
+3. Add the publisher password to Home Assistant secrets:
+   ```yaml
+   # /var/lib/hass/secrets.yaml
+   ntfy_password: <the homeassistant user's password>
+   ```
+4. Restart Home Assistant, then test from an automation / Developer Tools:
+   ```yaml
+   service: rest_command.ntfy_send
+   data:
+     message: "ntfy test"
+     title: "Home Assistant"
+     priority: high
+   ```
+5. Subscribe from the ntfy app as `admin` to receive the message.

+## Self-Review
+
+**Spec coverage:**
+- Module structure + options → Task 1. ✔
+- Server config (deny-all, port, firewall) → Task 1 (steps 1, 6). ✔
+- Homepage tile → Task 1. ✔
+- Registration in `default.nix` + enable on jupiter → Task 1 (steps 2–3). ✔
+- HA `rest_command` wiring, gated on HA profile, `!secret` password → Task 2. ✔
+- Manual provisioning runbook → Operator steps section. ✔
+- Verification (eval/build + nixfmt) → per-task steps. ✔
+- Out-of-scope items (no seeding, no sops, no reverse proxy) → honored; no tasks added for them. ✔
+
+**Placeholder scan:** No TBD/TODO/"handle edge cases". The one "similar to Task 1" note is accompanied by the full repeated code, per the no-placeholders rule. ✔
+
+**Type consistency:** `cfg.port`/`cfg.topic`/`cfg.haIntegration.enable` defined in Task 1 and used identically in Task 2. `rest_command.ntfy_send` name consistent across Task 2 and operator steps. Homepage tile shape matches sibling modules. ✔

+# ntfy self-hosted notification module — design
+
+Date: 2026-07-05
+Target machine: jupiter
+
+## Purpose
+
+Add a NixOS profile module that runs and configures a self-hosted
+[ntfy](https://ntfy.sh) notification server on jupiter, with authentication
+required, a homepage dashboard tile, and out-of-the-box plumbing so Home
+Assistant automations can publish push notifications.
+
+## Scope decisions (from brainstorming)
+
+- **Service:** ntfy (self-hosted server), not Apprise/Gotify/HA-only.
+- **Access control:** authentication required (`auth-default-access = deny-all`).
+- **Home Assistant:** the module wires an HA `rest_command` so automations can
+  send notifications out of the box.
+- **Credentials:** fully manual. The module runs the server and wires the HA
+  plumbing, but does **not** seed users or store any secret. The operator
+  provisions ntfy users/passwords by hand, and the only secret lives in Home
+  Assistant's `secrets.yaml` — never in the world-readable Nix store.
+
+## Module structure
+
+New module at `modules/environments/ntfy/default.nix` following the repo's
+standard profile pattern (`my.profiles.<name>` with `options` +
+`config = lib.mkIf cfg.enable { ... }`).
+
+Registration:
+1. Add `./ntfy` to the `imports` list in `modules/environments/default.nix`.
+2. Enable via `my.profiles.ntfy.enable = true;` in
+   `machines/jupiter/environments.nix`.
+
+### Options
+
+```nix
+options.my.profiles.ntfy = with lib; {
+  enable = mkEnableOption "ntfy notification server";
+
+  port = mkOption {
+    type = types.port;
+    default = 2586;
+    description = "HTTP port ntfy listens on.";
+  };
+
+  topic = mkOption {
+    type = types.str;
+    default = "ha";
+    description = "Topic Home Assistant publishes notifications to.";
+  };
+
+  haIntegration.enable = mkOption {
+    type = types.bool;
+    default = true;
+    description = "Wire a Home Assistant rest_command that publishes to ntfy.";
+  };
+};
+```
+
+## Server configuration
+
+```nix
+config = lib.mkIf cfg.enable {
+  services.ntfy-sh = {
+    enable = true;
+    settings = {
+      base-url            = "http://${hostName}:${toString cfg.port}";
+      listen-http         = ":${toString cfg.port}";
+      auth-file           = "/var/lib/ntfy-sh/user.db";
+      auth-default-access = "deny-all";
+    };
+  };
+
+  networking.firewall.allowedTCPPorts = [ cfg.port ];
+
+  my.homepage.services = [
+    {
+      group = "Services";
+      name = "ntfy";
+      description = "Push notifications";
+      href = "http://${hostName}:${toString cfg.port}";
+      icon = "ntfy.svg";
+    }
+  ];
+};
+```
+
+`hostName` is bound from `config.networking.hostName`, matching the pattern in
+the home-assistant and paperless modules.
+
+## Home Assistant wiring
+
+Applied only when ntfy, the HA integration flag, and the home-assistant profile
+are all enabled:
+
+```nix
+lib.mkIf (cfg.enable && cfg.haIntegration.enable
+          && config.my.profiles.home-assistant.enable) {
+  services.home-assistant.config.rest_command.ntfy_send = {
+    url = "http://${hostName}:${toString cfg.port}/${cfg.topic}";
+    method = "POST";
+    payload = "{{ message }}";
+    content_type = "text/plain";
+    username = "homeassistant";
+    password = "!secret ntfy_password";
+    headers = {
+      Title = "{{ title | default('Home Assistant') }}";
+      Priority = "{{ priority | default('default') }}";
+    };
+  };
+};
+```
+
+Notes:
+- `services.home-assistant.config` is an attrset that NixOS merges, so adding
+  `rest_command.ntfy_send` from this module composes with the config the
+  home-assistant module already defines.
+- `password = "!secret ntfy_password"` is a whole-value `!secret` reference. The
+  upstream home-assistant module unquotes such values when rendering the config
+  (the same mechanism the repo already relies on for `!include`), so the secret
+  resolves from `/var/lib/hass/secrets.yaml` at runtime and never enters the
+  Nix store. See `reference_nixos_ha_yaml_includes`.
+- `rest_command` is chosen over the `notify` REST platform because ntfy's
+  per-topic URL path plus header-based metadata map cleanly onto rest_command,
+  whereas the notify platform's fixed JSON payload fights ntfy's format.
+
+## Manual provisioning (operator runbook)
+
+Because credentials are fully manual, after the first `nixos-rebuild switch`
+run these once on jupiter:
+
+```bash
+# Dedicated publisher for Home Assistant, scoped to the ha topic
+ntfy user add homeassistant            # prompts for a password
+ntfy access homeassistant ha write-only
+
+# Admin account for the app / web UI
+ntfy user add --role=admin admin
+```
+
+Then add the homeassistant password to Home Assistant's secrets:
+
+```yaml
+# /var/lib/hass/secrets.yaml
+ntfy_password: <the homeassistant user's password>
+```
+
+Restart Home Assistant. Automations can then publish with:
+
+```yaml
+service: rest_command.ntfy_send
+data:
+  message: "Garage door left open"
+  title: "Alert"
+  priority: high
+```
+
+Subscribers (phone/desktop ntfy app) log in as `admin` (or another user granted
+read access) to receive messages.
+
+## Testing / verification
+
+- Build check: `nix build '.#nixosConfigurations.jupiter.config.system.build.toplevel'`
+  must succeed with the module enabled.
+- `nixfmt-rfc-style` clean on the new file.
+- Post-deploy manual verification (documented, not automated): create the users
+  above, publish a test message from HA, confirm it reaches a subscribed client.
+
+## Out of scope
+
+- No automated user/token seeding (explicitly deferred to manual provisioning).
+- No sops-nix setup (repo has dangling `config.sops.secrets` references, but
+  wiring up sops is a separate change and not required here).
+- No reverse-proxy / TLS termination (`behind-proxy` left default; LAN-only via
+  firewall).

-# mibook: choose terminal-only vs desktop at boot
-
-## Goal
-
-Let mibook boot to a text console by default, with KDE fully installed and
-launchable on demand. The user decides after boot whether they need the
-graphical desktop, without rebuilding the system.
-
-## Behavior
-
-- mibook boots to a text console (`multi-user.target`). SDDM and Plasma do
-  **not** start automatically.
-- KDE (SDDM + Plasma 6) remains fully installed.
-- Running `desktop` in the terminal starts the SDDM display manager, which
-  presents the graphical login screen; logging in there enters a Plasma 6
-  session.
-- No reverse command. To return to a text console, stop the display manager
-  (`sudo systemctl stop display-manager`) or reboot.
-- Other machines that enable the `kde-desktop` profile are unaffected; their
-  desktop still starts on boot.
-
-## Implementation
-
-### `modules/environments/kde-desktop/default.nix`
-
-Add an opt-out option to the existing profile:
-
-- New option `my.profiles.kde-desktop.startOnBoot`, a boolean defaulting to
-  `true`. The default preserves the current behavior for every consumer.
-- The existing `config` block (SDDM, Plasma 6, user packages) stays enabled
-  whenever the profile is enabled, regardless of `startOnBoot`.
-- When `startOnBoot = false`, additionally apply:
-  - `systemd.services.display-manager.wantedBy = lib.mkForce [ ];` so SDDM is
-    defined but not pulled in by any boot target.
-  - `systemd.defaultUnit = "multi-user.target";` so the boot target is the
-    text console.
-  - A `desktop` command provided via
-    `pkgs.writeShellScriptBin "desktop" "exec sudo systemctl start display-manager.service"`,
-    added to `environment.systemPackages`.
-
-### `machines/mibook/environments.nix`
-
-Set `kde-desktop.startOnBoot = false;` alongside the existing
-`kde-desktop.enable = true;`.
-
-## Testing / verification
-
-- `nix build '.#nixosConfigurations.mibook.config.system.build.toplevel'`
-  builds without error.
-- After `nixos-rebuild switch` on mibook: system boots to a TTY, no SDDM;
-  running `desktop` brings up the SDDM login and a working Plasma session.
-- Confirm jupiter (or any non-mibook consumer) is unchanged: its evaluated
-  `systemd.defaultUnit` / display-manager wantedBy are not altered.
-
-## Trade-offs
-
-- `desktop` relies on `sudo`; the user has sudo access, so no extra
-  configuration is required.
-- Chose "boot to terminal, launch on demand" over a GRUB boot-menu entry
-  because it is more robust across NixOS generations and needs no fragile
-  static kernel entries.
