+# Cross-region shard epidemic
+
+Erasure shards use **regional S3 keys** and **fleet gossip** so seeders prefer same-region peers before cross-region recovery.
+
+## S3 object layout
+
+- Key: `shards/{token}/{region}/{index}-{shard_hash}.bin`
+- Metadata: `region`, `shard-index`, `token`, `shard-hash`, `shard-advert` (`region:shard_index`)
+
+## Gossip
+
+`have_shard` records include `region` and `shard_advert` (`us-east-1:2`). Agents rank peers: LAN → same region → other regions → CloudFront → C2.
+
+## CRR (operator-applied)
+
+1. Set in `data/config.json` under `server`:
+   - `aws_s3_shard_bucket`, `aws_s3_shard_region`
+   - `aws_s3_crr_dest_bucket`, `aws_s3_crr_dest_region`
+   - `aws_s3_replication_role_arn` (optional)
+   - `aws_cloudfront_domain` (edge fetch before C2)
+2. Fetch generated rule: `GET /api/v1/spread/aws-s3-crr-template`
+3. Apply the JSON to the **source** bucket replication configuration (AWS console or CLI).
+4. Standalone template reference: `templates/spread/aws/s3-crr-rule.json`
+
+No server-side AWS API calls are made; the operator owns IAM and replication setup.
+
+## Agent region
+
+Agents resolve region from EC2 IMDS (`placement/region`), falling back to `aws_s3_shard_region` in `spread_policy` at auth.
