Lazily retry lichess token fetch; demand-load lichess package

gpg-agent may not have a cached passphrase yet when the top-level setq
runs at Emacs startup, so a cold agent makes 'pass' fail silently
(stderr redirected) and leaves lichess-token permanently empty for the
session. Retry the fetch right before each use instead of only once
at startup.

+Features are auto-discovered by `import-tree` — no central imports file. Each feature's
+`default.nix` registers itself via `config.flake.modules.homeManager.<name>`. Modules are
+then explicitly imported in `home-manager/home.nix` via `suiteModules.homeManager.<name>`.
+
+**Where to put a new feature:**
+- Shared / reusable across machines → `azos-core/features/<name>/default.nix`
+- Machine-specific → `azos/features/<name>/default.nix`
+
+## Code Style Guidelines
 
 ### Nix Module Template
 
+All features follow this flake-parts registration pattern:
+
 ```nix
-{
+{...}: {
+  config.flake.modules.homeManager.<name> = {
     lib,
     config,
     pkgs,
     ...
-}: let
+  }: {
-  isEnabled =
+    options.azos.<name>.enable = lib.mkOption {
-    config.azos.<module-name>.enable;
+      default = false;
-in {
-  options.azos.<module-name>.enable = lib.mkOption {
-    default = true;
       example = true;
       type = lib.types.bool;
     };
 
-  config = lib.mkIf isEnabled {
+    config = lib.mkIf config.azos.<name>.enable {
-    home.packages = with pkgs; [ pkg1 pkg2 ];
+      home.packages = with pkgs; [pkg1 pkg2];
+    };
   };
 }
 ```
 
 ### Naming Conventions
-- Option paths: `config.azos.<module-name>.<option>`
+- Option paths: `azos.<module-name>.<option>`
-- Enable option: `enable` (bool), default `true`
+- Module names: kebab-case (`git-config`, `claude-memory`)
-- Module names: kebab-case (`libreoffice.nix`, `git-config.nix`)
+- Feature directories: kebab-case, one `default.nix` per feature
-- Option names: may differ from filename (e.g., `git.nix` uses `azos.git-config`)
+- Variables: kebab-case
-- Variables: kebab-case (`isEnabled`)
 
 ### Formatting
 - Indentation: 2 spaces
-- Let bindings: multi-line with `isEnabled` on its own line
+- Packages: `with pkgs; [pkg1 pkg2]` (no trailing semicolon inside list)
-- Packages: Use `with pkgs; [ ... ]` syntax
 
 ### Imports
-- Always include `{...}` for module args
+- Always include `{...}` for the outer module args
-- Standard args: `lib, config, pkgs, ...`
+- Inner module args: `lib, config, pkgs, ...`
-- NixOS config args: `inputs, outputs, lib, config, pkgs, ...`
-- Use `./relative/path.nix` for local imports
 
 ### Option Patterns
-- Boolean enable: `lib.mkOption { default = true; example = true; type = lib.types.bool; }`
+- Boolean enable: `lib.mkOption { default = false; example = true; type = lib.types.bool; }`
-- Conditional config: `lib.mkIf isEnabled { ... }`
+- Conditional config: `lib.mkIf config.azos.<name>.enable { ... }`
-- User-overridable: `lib.mkDefault`
+- Auto-enable a dependency: `azos.<dep>.enable = lib.mkDefault true;`
 - Force value: `lib.mkForce` (sparingly)
 
+### Extensible Options
+For options that multiple modules should be able to contribute to, use attrset options:
+
+```nix
+options.azos.<name>.things = lib.mkOption {
+  default = {};
+  type = lib.types.attrsOf lib.types.path;  # or lines, str, etc.
+};
+```
+
+Any module can then add entries without modifying the owning feature. Examples in use:
+- `azos.claude.globalSkills` — attrset of skill name → markdown file path
+- `azos.claude.globalMdSections` — attrset of key → markdown string (merged into `~/.claude/CLAUDE.md`)
+
 ### Home-Manager vs NixOS
 - Home-manager: `home.packages`, `home.file`, `programs.<program>`
 - NixOS: `config.services`, `environment.systemPackages`
 
+### Deploying Files
+- Static file: `home.file."dest".source = ./file;`
+- Generated text: `home.file."dest".text = "...";`
+- Runtime script (e.g. merging JSON at activation): `home.activation.<name> = lib.hm.dag.entryAfter ["writeBoundary"] ''...'';`
+
 ### Suites System
-Modules are organized into suites (defined in `azos-core/`):
+Top-level suites group related features (defined in `azos-core/`):
-- `azos.suites.base` - Base packages and config
+- `azos.suites.base` — base packages and config
-- `azos.suites.editor` - Editor tools
+- `azos.suites.editor` — editor tools
-- `azos.suites.dev` - Development tools
+- `azos.suites.dev` — development tools
-- `azos.suites.station` - Desktop applications
+- `azos.suites.station` — desktop applications
-- `azos.suites.exwm` - EXWM window manager
+- `azos.suites.exwm` — EXWM window manager
-- Enable in `home-manager/home.nix` with `azos.suites.<name>.enable = true;`
+
+The machine suite (`azos.suites.lauretta`) enables the relevant suites for this machine.

 ## Adding New Modules
 
-1. Create file in `modules/home-manager/` or `modules/nixos/`
+1. Create `features/<name>/default.nix` (machine-specific) or `azos-core/features/<name>/default.nix` (shared)
-2. Add import to `modules/<type>/default.nix` (alphabetical)
+2. Use the module template above
-3. Use module template above
+3. Add `suiteModules.homeManager.<name>` to the imports list in `home-manager/home.nix`
 4. Run `nix fmt`
 
+> **Submodule gotcha**: New files in `azos-core/` must be `git add`-ed inside the submodule
+> before `nix build` will see them — Nix flakes only evaluate git-tracked files.
+> ```bash
+> cd azos-core && git add features/<name>/
+> ```
+
+## Claude Integration
+
+Claude Code is integrated with this environment via several azos-core features:
+
+| Feature | Option | What it does |
+|---------|--------|--------------|
+| `azos-core/features/claude-memory` | `azos.claude-memory.enable` | Registers org-roam-mcp as a global MCP server in `~/.claude.json` |
+| `azos-core/features/claude-skills` | `azos.claude-skills.enable` | Deploys skills to `~/.claude/commands/` and content to `~/.claude/CLAUDE.md` |
+| `azos/features/claude` | `azos.claude.enable` | Installs claude-code, auto-enables the above two |
+
+### Adding Claude skills or standing instructions
+From any module — no need to touch azos-core:
+```nix
+azos.claude.globalSkills.my-skill = ./skills/my-skill.md;
+azos.claude.globalMdSections.my-rule = ''
+  # My Rule
+  Always do X when Y.
+'';
+```
+See `azos-core/features/claude-skills/README.md` for full documentation.

+# Homey Alert — sending ntfy notifications when tasks finish
+
+Use `homey-alert` to push notifications to Aner's homelab ntfy server when long tasks complete.
+
+## When to use proactively
+
+When running (or suggesting) a command that will take more than ~30 seconds — training runs,
+builds, deploys, downloads, test suites — append a notification automatically. Don't wait to
+be asked.
+
+## Local commands
+
+Append after the command so it fires on success only (`&&`) or always (`;`):
+
+```bash
+# Notify on success only
+long_cmd && homey-alert "Task done"
+
+# Always notify (even on failure) — prefer this for deploys/training
+long_cmd; homey-alert -t "Training" -p high -T "$([ $? -eq 0 ] && echo white_check_mark || echo x)" "Exited $?"
+```
+
+## Remote commands (SSH / training machines)
+
+Remote machines don't have `homey-alert`. Use `-r`/`--print-remote` to get a self-contained
+`curl` command with the token already embedded. The `$(...)` expands **locally**; the resulting
+command string is what the remote machine executes.
+
+```bash
+ssh user@host "python train.py && $(homey-alert -r -t 'Training' -p high -T white_check_mark 'Model finished')"
+```
+
+The remote machine only needs `curl` (universally available).
+
+## Flags
+
+| Flag | Short | Values / notes |
+|------|-------|----------------|
+| `--title TITLE` | `-t` | Notification title |
+| `--priority PRIO` | `-p` | `min` / `low` / `default` / `high` / `urgent` |
+| `--tags TAGS` | `-T` | Comma-separated emoji shortcodes: `white_check_mark`, `x`, `warning`, `rotating_light`, `tada` |
+| `--print-remote` | `-r` | Print curl command instead of running (embed token locally, run remotely) |
+
+## Choosing priority and tags
+
+- Routine completion (backup, build): `default` priority, `white_check_mark`
+- Training / long job: `high` priority, `white_check_mark` on success / `x` on failure
+- Something broke: `urgent` priority, `rotating_light`

+** Elfeed Nextcloud News Sync
+
+[[https://github.com/fasheng/elfeed-protocol][elfeed-protocol]] adds an =owncloud+= protocol that speaks the
+ownCloud News API, which the Nextcloud News app also implements, so
+it syncs elfeed's feed list and read/unread state with the Nextcloud
+News app instead of just reading a local feed list one-way.
+
+Reuses the same =zakobar.com= pass entry as the CalDAV sync above,
+since it's the same Nextcloud account.
+
+As of elfeed-protocol 1.0.0 (paired with elfeed >= 4.0.0), the
+credentials go directly on =elfeed-feeds= — the older
+=elfeed-protocol-feeds= variable is dead: setting it only logs a
+deprecation warning, and =elfeed-feeds= ends up with the bare URL
+and no =:password=, so requests silently authenticate with an empty
+password and nothing ever lands in the db.
+
+This =:config= block runs synchronously the first time =elfeed= is
+loaded (i.e. the first =M-x elfeed= of the session), with no user
+keypress behind it the way =azos/caldav-sync= has. Fetching the
+password with =shell-command-to-string= there used to deadlock
+Emacs whenever the GPG PIN cache had expired: that call blocks
+Emacs's single thread on the =pass|gpg= subprocess, but
+=pinentry-emacs= (see the GPG Pinentry section above) needs Emacs's
+command loop running to answer its loopback prompt — so Emacs waits
+on gpg-agent while gpg-agent waits on Emacs. Fetching the password
+with =make-process= instead keeps the command loop alive, so
+=pinentry-emacs= can prompt normally; =elfeed-feeds= and
+=elfeed-protocol-enable= are only set once the process sentinel
+fires. Same stderr-redirect reasoning as before, to keep a stray
+gpg/pass warning off the captured password.

+** Elfeed Full Article Fetch
+
+Many feeds only publish a short excerpt. elfeed >= 4.0 has built-in
+commands for this — =f= (=elfeed-show-fetch-link=) fetches the
+linked page and appends it to the show buffer, =R=
+(=elfeed-show-readable=) strips the fetched page down to
+article text via eww's readability scorer — and both can run
+automatically via =elfeed-show-update-hook=, gated on a feed's
+=:fetch-link=/=:readable= metadata.
+
+That gating keys off an exact match on the feed's URL/id in
+=elfeed-feeds=, which breaks for ownCloud/Nextcloud subfeeds:
+elfeed-protocol synthesizes a per-subfeed id of the form
+=<host-url>::<subfeed-url>= that never appears in =elfeed-feeds=
+(only the bare host URL does), so the metadata lookup always misses
+and the stock hooks never fire. Replacing them with unconditional
+versions makes full-text + readable-mode the default for every
+entry instead.

+** Lichess
+
+=lichess.org= in pass already holds the website login password, and

+the API token can't live under that same entry without colliding.
+Store it separately under =lichess.org/token= (=pass insert
+lichess.org/token=) and set the =lichess-token= variable directly —
+=lichess-token= (the function) checks this variable before falling
+back to =auth-source=, so this takes precedence without disturbing
+the existing =lichess.org= entry or its consumers (e.g. browserpass).
+
+=shell-command-to-string= merges stderr into its return value, so any
+gpg/pass warning on stderr (e.g. an unsafe-permissions notice) would
+otherwise get concatenated onto the token and break auth silently.
+Redirect stderr away so only the token itself is ever captured.
