# Enable Reachability — Draft Skeleton (2025-12-05 UTC)

Status: draft placeholder. Inputs pending: DOCS-SIG-26-007, notifications hooks (058_NOTY0101), rollout telemetry contract.

## Purpose
- Describe why reachability is being enabled and expected outcomes.

## Rollout Phases
- Phase 0: prerequisites (feature flags, config keys).
- Phase 1: limited tenants / canaries.
- Phase 2: org-wide rollout with monitoring gates.

## Fallbacks
- How to disable/revert; config toggles; cache/queue drains.

## Monitoring & Alerts
- Metrics to watch (ingest lag, signal volume, error ratios).
- Alert thresholds and runbooks (link when available).

## Controls & Policy
- Imposed rule reminder; RBAC/tenant scope considerations.

## Open TODOs
- Fill concrete config keys and examples when DOCS-SIG-26-007 lands.
- Add notification hook wiring details from 058_NOTY0101.
