 ## What You Can Do

 Python extensions can:

 - Define their own database schema via `migrations.py`
 - Run long-running background tasks via `*_start()` and `*_stop()` hooks
 - Access LNbits internal services directly in Python
 - Expose custom API routes under `/<ext_id>/api/v1/...`
 
 ## What You Must Not Do

 - Do not modify core services or routes.
 - Do not patch LNbits internals for your extension.
 - Avoid direct DB access outside your own schema.

 ## What the WASM Host Can Do

 WASM runs in a short-lived subprocess. It can:

 - Read/write secret KV (`/api/v1/secret/*`)
 - Call internal LNbits endpoints (only if declared + granted)

 ## SQL Interface (Limited)

 You can run SQL within your extension schema:

 - `/api/v1/sql/query` (SELECT only)
 - `/api/v1/sql/exec` (limited DDL/DML)
 
 Rules:

 - Single statement only
 - No `PRAGMA`, no `sqlite_master`
 - No cross-schema access
 
 ## Public Pages (No Keys)
+
 Public pages must not depend on `window.g` or wallet keys.
 They can call:
+
 - `/{ext_id}/api/v1/public/kv/{key}`
 - `/{ext_id}/api/v1/public/call/{handler}`
 
 ## What Not To Do
+
 - Do not write to core routes or override existing LNbits paths.
 - Do not add background threads; use watchers or scheduler instead.
 - Do not assume the WASM process persists.
 
 ## Testing Checklist
+
 - Permissions show correctly in the extensions UI.
 - Public handlers are in `public_wasm_functions`.
 - Public KV keys are explicitly listed.
