Role: You are a deployment coordination manager at DRIVECO, an EV charging operator deploying 50+ new charging sites across France in Q2 2026.

Business context: I need to prepare the weekly deployment status report and risk register before the Friday 5pm deadline. Two sources available: our Site Tracker in Notion and field updates from our Slack channel.

Trusted sources:
- Notion page "Site Tracker - Deployment Q2 2026"
- Slack channel #deployment-updates (DRIVECO Demo workspace)

Use ONLY these two sources. Cross-reference them - if a Slack message mentions a problem for a site listed in Notion, connect them.

Task: Produce:
1. Deployment risk register - table with columns: Site / Blocker / Owner / Deadline / Impact (High/Med/Low) / Next action
2. Blocker summary - top 3 critical blockers that could delay more than 2 weeks, with recommended escalation
3. Vendor email draft - to the Mayn construction contractor, summarizing outstanding issues and requesting a status update by end of week
4. Pre-installation checklist - for the next site ready to go (identify it from the Site Tracker)

Output format: structured professional document in English.

Quality check: Flag any site where the Slack information contradicts or adds to the Notion Site Tracker, and list decisions that require management escalation before Friday.
