+# Absurd-SQLite
+
+Absurd-SQLite is a SQLite based durable execution engine designed for personal / homelab / edge computing environments.
+
+This project is based on the PostgreSQL implementation from [absurd](https://github.com/earendil-works/absurd).
+
+## Key Concepts
+
+A task is subdivided into steps that act as checkpoints. Tasks can suspend (for sleep or events) and resume without data loss.
+State data is stored in the SQLite tables below:
+
+- Queues: `absurd_queues` scopes all durable execution by `queue_name`.
+- Tasks: `absurd_tasks` stores task definitions, parameters, headers, retry/cancel info, idempotency keys, and task state.
+- Runs: `absurd_runs` represents per-attempt execution for a task with claim/lease timing, availability, and results/failures.
+- Checkpoints: `absurd_checkpoints` tracks named task checkpoints with optional state and run ownership.
+- Events: `absurd_events` stores emitted events with JSON payloads scoped by queue and event name.
+- Waits: `absurd_waits` records task steps waiting on events or timeouts.
+
+To interact with the system, a SQLite extension is provided and exposed various SQL functions.
+
+## Repository Structure
+
+- `absurd-sqlite-extension`: Core Rust crate providing the SQLite extension, engine logic, and schema migrations.
+- `standalone`: Tauri + SvelteKit desktop app.
+- `sdks`: Client SDKs for different languages.
+- `samples`: Example applications demonstrating usage.
+
+## Development
+
+General rule: please make sure to lint, format, and test code after making changes. No need to ask for human confirmation
+before running linters / formatters / tests.
+
+Please follow the sub-project README.md / AGENTS.md for detailed instructions.
