 StreamHive is a **Go library and CLI** for experimenting with distributed, content-addressed storage. It ships a production-minded **TCP transport** (context-aware listen/dial, TLS hooks, framing, metrics, limits), a **length-prefixed wire format** (`SHV1`), a typed **blob replication protocol**, memory and file-backed **blob stores**, and operational endpoints (`/livez`, `/readyz`, `/metrics`, `/metrics/prometheus`).

 # Release Checklist
 
-Use this checklist for StreamHive `v0.3.0`, the first release with static blob replication, reconnect/backoff, and file-backed storage.
+Use this checklist for StreamHive releases. The current target is `v0.4.0`, the first release with content-addressed CLI puts, startup anti-entropy sync, Prometheus text metrics, and a CI-verified 3-node Compose rehydration demo.
 
 ## Preflight
 
 ```bash
 go test ./...
 go test -bench=. -benchmem -run '^$' ./...
 P2P_ADDR=127.0.0.1:17070 HEALTH_ADDR=127.0.0.1:18080 make demo-replication

+2. Move completed [CHANGELOG.md](../CHANGELOG.md) entries from `[Unreleased]` into `[MAJOR.MINOR.PATCH] - YYYY-MM-DD`.
 3. Commit the version bump:
 
 ```bash
 git add internal/version/version.go CHANGELOG.md
-git commit -m "chore: release v0.3.0"
+git commit -m "chore: release v0.4.0"
 ```

 ## Release Notes
 
 Highlight:
 
-- Static `blob.put` replication over SHV1 frames.
-- CLI demo path with `-replicate`, `-put-key`, `-put-data`, and `-exit-after-put`.
-- Durable receiver storage with `-store-dir`.
-- Static peer lists plus reconnect/backoff via `-peers` and `-peer-reconnect`.
-- `/metrics` counters for replication and transport behavior.
-- `FileStore` behind the `storage.BlobStore` interface.
+- SHA-256 content key helpers and `-put-content-key`.
+- `blob.has`, `blob.get`, and `blob.missing` anti-entropy messages.
+- Startup anti-entropy sync for static `-replicate` peers.
+- Durable receiver storage with `-store-dir` and `-list-keys`.
+- `/metrics` JSON counters and `/metrics/prometheus` text format.
+- 3-node Docker Compose demo with node restart rehydration, verified in CI.
