Plugin loading mechanism documented

When the plugin loading mechanism is undocumented, a developer who has built a working plugin cannot install it. They do not know whether to place files in a plugins/ directory, add an entry to a config file, or call a registration function. ISO 25010 maintainability.modularity requires that the extension point be clearly defined; an undocumented loading mechanism makes the extension point inaccessible despite technically existing. The barrier affects plugin users as much as plugin authors — a correctly built plugin that cannot be installed provides no value.

Document the full loading flow in src/plugins/README.md or docs/plugins.md, covering file placement, naming conventions, configuration entries, and activation sequence. Include a working import pattern.

// src/plugins/loader.ts — dynamic plugin loading
const plugins = await import(`./plugins/${name}/index.ts`);

Also document whether plugins can be hot-loaded after startup or require a restart.

• ID: loading-mechanism

• Severity: high

• What to look for: Check that the mechanism for discovering, loading, and activating plugins is clearly defined and documented. Plugin authors and users need to know: where do plugins live, how does the host find them, and how are they activated? Look for documentation or clear code covering:

  1. File system discovery — "Place plugins in the plugins/ directory" or "Plugins are npm packages matching my-app-plugin-*"
  2. Configuration-based — "Add plugin names to the plugins array in config.json" or "Add to plugins field in package.json"
  3. Registry-based — "Install from the plugin marketplace at..."
  4. Programmatic — "Call app.register(plugin) in your setup file" Also check that the loading sequence is documented: when do plugins load relative to the host's startup? Can plugins be loaded after startup (hot-loading)?

• Pass criteria: Count all plugin loading strategies. The plugin loading mechanism is documented. A new user can understand: where to put a plugin, how the host discovers it, and when it gets activated. The mechanism is consistent (not three different undocumented ways to load plugins). At least 1 dynamic loading mechanism must exist (lazy import, worker, iframe).

• Fail criteria: No documentation on how plugins are discovered or loaded. A new user cannot determine: where to put a plugin file, how the host finds it, what triggers loading. OR multiple loading mechanisms exist and none is documented as the primary approach.

• Skip (N/A) when: Never — every plugin system has a loading mechanism. If it's undocumented, this check should fail.

• Detail on fail: "No documentation explains how plugins are loaded. The source code shows plugins are loaded from a plugins/ directory via dynamic import, but this is not documented anywhere. A user looking to install a third-party plugin would not know where to place it or what file naming convention to follow."

• Remediation: Document the loading flow in src/plugins/README.md or docs/plugins.md:

  // src/plugins/loader.ts — dynamic plugin loading
  const plugins = await import(`./plugins/${name}/index.ts`)
