# T-638: check-tier0 Watchtower link — emit approval page URL in Tier 0 block message

## Context

T-636 Phase 1 deliverable. When check-tier0.sh blocks a command, it currently only shows `./bin/fw tier0 approve` (CLI). Should also show the Watchtower /approvals URL so the human can approve in browser. Spike 3 identified this as the highest-value change (~10 lines). Research: docs/reports/T-636-unified-approval-experience.md

## Acceptance Criteria

### Agent
- [x] check-tier0.sh block message includes Watchtower /approvals URL
- [x] URL uses dynamic hostname + port detection (same pattern as lib/review.sh)
- [x] Both CLI and Watchtower options shown (not replacing CLI path)

## Verification

grep -q '/approvals' agents/context/check-tier0.sh
