## When to Use

Use this skill in production deployment pipelines, Site Reliability Engineering (SRE) release controls, and CI/CD deployment gateways for quantitative trading systems. Code deployments during major macro economic announcements (FOMC Rate Decisions, CPI, Non-Farm Payrolls) or daily market open/close volatility windows carry extreme operational risk. A minor deployment glitch during a market volatility surge can cause massive financial losses. This module intercepts deployment requests and enforces automated freeze buffers.

## Prerequisites

- Macro Event Schedule (`event_name`, `event_timestamp_iso`, `pre_event_buffer_minutes`, `post_event_buffer_minutes`).
- Daily Market Open/Close freeze parameters (e.g. 15 min before/after Market Open/Close).

## Workflow

1. **Macro Calendar & Market Open/Close Registration**:
   - Register scheduled macro events and daily volatility freeze windows.
2. **Deployment Request Audit**:
   - Inspect deployment request timestamp, target environment (`PRODUCTION` vs `STAGING`), and service name.
3. **Freeze Window Interception**:
   - Check if request timestamp falls within any active pre/post event freeze buffer.
   - If freeze active & `is_emergency_hotfix == False` $\implies$ Block deployment (`DEPLOYMENT_BLOCKED_FREEZE_ACTIVE`).
4. **Break-Glass Emergency Protocol**:
   - If `is_emergency_hotfix == True`, require dual sign-off (`risk_officer_approval` AND `head_of_trading_approval`).
5. **Audit Report Generation**: Output structured `DeploymentFreezeAuditReport`.

## Common Pitfalls

- **Deploying Right Before FOMC Releases**: Shipping routine algorithm updates 10 minutes before an FOMC rate decision, causing execution engine crashes during peak volatility.
- **Single-Person Emergency Bypasses**: Allowing single developers to bypass deployment freezes without Risk Officer and Head of Trading dual authorization.
- **Blanket Freezes Halting Non-Production Builds**: Applying strict production freezes to staging/research environments, blocking developer research.

## Verification

- Instantiate `DeploymentFreezeGuardEngine`. Register FOMC Rate Decision on June 12 at 14:00 EST with 60-min pre/post buffers (13:00 to 15:00 EST freeze). Submit production deployment request for 13:30 EST. Verify engine blocks deployment (`DEPLOYMENT_BLOCKED_FREEZE_ACTIVE`). Submit emergency hotfix request with dual sign-off. Verify engine approves break-glass deployment.
- Run `python scripts/test_deployment_freeze_guard.py`.
