Chaos Engineering & Fault Injection Page

Create an Angular page for managing chaos engineering experiments using the existing chaos module.

Backend Endpoints Needed

GET    /admin/chaos/experiments        — List experiments
POST   /admin/chaos/experiments        — Create experiment
PUT    /admin/chaos/experiments/{id}   — Update experiment
POST   /admin/chaos/experiments/{id}/start  — Start experiment
POST   /admin/chaos/experiments/{id}/stop   — Stop experiment
GET    /admin/chaos/experiments/{id}/status — Status & results
DELETE /admin/chaos/experiments/{id}   — Delete experiment

UI Requirements

Experiment Templates

• Latency injection (add delay to read/write)
• Error injection (X% of operations fail)
• Disk full simulation
• Connection drops
• Slow compaction
• Memory pressure

Experiment Creation

• Name, fault type, target operations
• Intensity slider (0-100%)
• Duration and optional schedule

Active Experiments

• Status cards with remaining time
• Live metrics (error rate, latency impact)
• Emergency stop button
• Past experiment history table

Safety Features

• Explicit confirmation before starting
• Auto-stop after configured duration
• Cannot affect admin endpoints
• Full audit log

Acceptance Criteria

• Experiment list displays correctly
• Can create experiment from template
• Experiment starts and stops correctly
• Live metrics update during experiment
• Auto-stop works on duration expiry
• Safety confirmations present
