## Issue 1: Restore diffuser node implementation
**Labels:** `enhancement`, `node`
**Priority:** Medium
The `nodes/diffuser/` directory contains only `.git`, `LICENSE`, and `README.md` — no implementation. There was a previous experimental version. Needs:
- Retrieve original diffuser logic from user/backup
- Rebuild to current three-layer architecture (wrapper `.js` + `src/nodeClass.js` + `src/specificClass.js`)
- Use `require('generalFunctions')` barrel imports
- Add config JSON in `generalFunctions/src/configs/diffuser.json`
- Register under category `'EVOLV'` with appropriate S88 color
- Add tests
**Blocked on:** User providing original diffuser logic/requirements.

## Issue 2: Relocate prediction/ML modules to external service
**Labels:** `enhancement`, `architecture`
**Priority:** Medium
TensorFlow-based influent prediction code was removed from monster node (was broken/incomplete). The prediction functionality needs a new home:
- LSTM model for 24-hour flow prediction based on precipitation data
**Note:** monster_class.js is ~500 lines of domain logic. Keep sampling_program(), aggregation, AQUON integration intact.

## Issue 4: Clean up inline test/demo code in specificClass files
**Labels:** `cleanup`
**Priority:** Low
Several specificClass files have test/demo code after `module.exports`:
-`pumpingStation/src/specificClass.js` (lines 478-697): Demo code guarded with `require.main === module` — acceptable but could move to `test/` or `examples/`
-`machineGroupControl/src/specificClass.js` (lines 969-1158): Block-commented test code with `makeMachines()` — dead code, could be removed or moved to test file

## Issue 5: DashboardAPI node improvements
**Labels:** `enhancement`, `security`
**Priority:** Low
- Bearer token now relies on `GRAFANA_TOKEN` env var (hardcoded token was removed for security)
