+# Scheduled Actions Design
+
+## Goal
+
+Allow CorePHP Actions to declare their own schedule via PHP 8.1 attributes, persist schedules to the database for runtime control, and auto-discover them during deploy — replacing the need for manual `routes/console.php` entries and enabling admin visibility.
+
+## Architecture
+
+**Attribute-driven, database-backed scheduling.** Actions declare defaults with `#[Scheduled]`. A sync command persists them to a `scheduled_actions` table. The scheduler reads the table at runtime. Admin panel provides visibility and control.
+
+**Tech Stack:** PHP 8.1 attributes, Laravel Scheduler, Eloquent, existing CorePHP module scanner paths.
+
+---
+
+## Components
+
+### 1. `#[Scheduled]` Attribute
+
+**File:** `src/Core/Actions/Scheduled.php`
+
+```php
+#[Attribute(Attribute::TARGET_CLASS)]
+class Scheduled
+{
+    public function __construct(
+        public string $frequency,            // 'everyMinute', 'dailyAt:09:00', 'weeklyOn:1,09:00'
+        public ?string $timezone = null,     // 'Europe/London' — null uses app default
+        public bool $withoutOverlapping = true,
+        public bool $runInBackground = true,
+    ) {}
+}
+```
+
+The `frequency` string maps to Laravel Schedule methods. Colon-separated arguments:
+- `dailyAt:09:00` → `->dailyAt('09:00')`
+- `weeklyOn:1,09:00` → `->weeklyOn(1, '09:00')`
+- `everyMinute` → `->everyMinute()`
+- `hourly` → `->hourly()`
+- `monthlyOn:1,00:00` → `->monthlyOn(1, '00:00')`
+
+### 2. `scheduled_actions` Table
+
+```
+scheduled_actions
+├── id                    BIGINT PK
+├── action_class          VARCHAR(255) UNIQUE  — fully qualified class name
+├── frequency             VARCHAR(100)         — from attribute, admin-editable
+├── timezone              VARCHAR(50) NULL
+├── without_overlapping   BOOLEAN DEFAULT true
+├── run_in_background     BOOLEAN DEFAULT true
+├── is_enabled            BOOLEAN DEFAULT true — toggle in admin
+├── last_run_at           TIMESTAMP NULL
+├── next_run_at           TIMESTAMP NULL       — computed from frequency
+├── created_at            TIMESTAMP
+├── updated_at            TIMESTAMP
+```
+
+No tenant scoping — these are system-level platform schedules, not per-user.
+
+### 3. `ScheduledAction` Model
+
+**File:** `src/Core/Actions/ScheduledAction.php`
+
+Eloquent model with:
+- `scopeEnabled()` — where `is_enabled = true`
+- `markRun()` — updates `last_run_at`, computes `next_run_at`
+- `frequencyMethod()` / `frequencyArgs()` — parses `frequency` string
+
+### 4. `ScheduledActionScanner`
+
+**File:** `src/Core/Actions/ScheduledActionScanner.php`
+
+Scans module paths for classes with `#[Scheduled]` attribute using `ReflectionClass::getAttributes()`.
+
+Reuses the same scan paths as `ModuleScanner`:
+- `app/Core`, `app/Mod`, `app/Website` (application)
+- `src/Core`, `src/Mod` (framework)
+
+Returns: `array<class-string, Scheduled>` — map of class name to attribute instance.
+
+### 5. `schedule:sync` Command
+
+**File:** `src/Core/Console/Commands/ScheduleSyncCommand.php`
+
+```
+php artisan schedule:sync
+```
+
+- Runs `ScheduledActionScanner`
+- Upserts `scheduled_actions` rows:
+  - **New classes** &rarr; insert with attribute defaults
+  - **Removed classes** &rarr; set `is_enabled = false` (don't delete)
+  - **Existing rows manually edited** &rarr; preserve the override (only overwrite if frequency matches the previous attribute default)
+- Prints summary: `3 added, 1 disabled, 12 unchanged`
+- Run during deploy/migration
+
+### 6. `ScheduleServiceProvider`
+
+**File:** `src/Core/Actions/ScheduleServiceProvider.php`
+
+Registered in framework boot, console context only.
+
+- Queries `scheduled_actions` where `is_enabled = true`
+- For each row:
+  ```php
+  Schedule::call(fn () => $row->action_class::run())
+      ->$frequencyMethod(...$frequencyArgs)
+      ->withoutOverlapping()  // if set
+      ->runInBackground()     // if set
+      ->timezone($timezone)   // if set
+  ```
+- Updates `last_run_at` via `after()` callback
+
+---
+
+## Flow
+
+### Deploy/Migration
+
+```
+artisan schedule:sync
+    ├── ScheduledActionScanner scans #[Scheduled] attributes
+    ├── Upsert scheduled_actions table
+    └── Summary: "3 added, 1 disabled, 12 unchanged"
+```
+
+### Runtime (every minute)
+
+```
+artisan schedule:run
+    └── ScheduleServiceProvider
+            ├── Query scheduled_actions WHERE is_enabled = true
+            ├── For each: Schedule::call(fn () => ActionClass::run())
+            └── After each: update last_run_at, compute next_run_at
+```
+
+### Admin Panel (future, not MVP)
+
+Table view of `scheduled_actions` with enable/disable toggle, frequency editing, last_run_at display.
+
+---
+
+## Usage Example
+
+```php
+<?php
+
+declare(strict_types=1);
+
+namespace Mod\Social\Actions;
+
+use Core\Actions\Action;
+use Core\Actions\Scheduled;
+
+#[Scheduled(frequency: 'dailyAt:09:00', timezone: 'Europe/London')]
+class PublishDiscordDigest
+{
+    use Action;
+
+    public function handle(): void
+    {
+        // Gather yesterday's commits across repos
+        // Summarise changes
+        // Post to Discord webhook
+    }
+}
+```
+
+No Boot registration needed. No `routes/console.php` entry. The scanner discovers it, `schedule:sync` persists it, the scheduler runs it.
+
+---
+
+## Migration Strategy
+
+- **Existing `routes/console.php` commands** stay as-is. No breaking changes.
+- **New scheduled work** uses `#[Scheduled]` actions going forward.
+- **Over time**, existing commands can be migrated to actions at natural touch points.
+
+## First Consumers
+
+- Discord daily digest (summarise repo changes, post to Lethean Discord)
+- Social media scheduled posting triggers
+- Image resizing queue triggers (VIP feature)
+- AltumCode cron replacements (longer term — wget loops work for now)
+- Sync operations (biolinks, analytics data, etc.)
+
+## Non-Goals (MVP)
+
+- Per-tenant scheduling (system-level only for now)
+- Admin panel UI (just the table/model/command/provider)
+- Caching scanner results (premature optimisation)
+- Replacing existing `routes/console.php` entries (gradual migration)
