bare-os-protocol
Shared wire format and constants for the Bare operating system monorepo: Hyperswarm topic, 512-byte MBR layout, and Protomux bare-os-v1 seed-channel message shapes.
When to use: depend on this package when building a compatible seeder or booter, fuzz-testing MBR/topic stability, or reusing kernel feature bit masks in tooling.

What it provides
PROTOCOL_NAME,TOPIC_STRING— Protomux channel name and swarm topic input string (bare-os-v1)topicKey()— 32-byte topic forswarm.join()BLOCK_SIZE,MBR_MAGIC— 512-byte MBR, magicBIOSat offset 0buildMbr/parseMbr— Pack/unpack primary + optional failover Hyperdrive keyssetupSeedChannel— Wire Protomux messages 0–6 for RAM block reads, gossip bitfield, manifest path search, RPC (incl.bare_os.capabilitieswithbits…bits11when non-zero, typed errors for unknown RPC methods,bare_os.replication_status,bare_os.replication_queue, extended RPC short names inseed-rpc-methods.js,bare_os.gossip), anddrive.replicate. Message 0/1 is role-agnostic: any peer withlocalRAMblock0can answer MBR reads.
Subpath exports: bare-os-protocol/constants.js, bare-os-protocol/messages (compact-encoding schemas), bare-os-protocol/kernel-feature-bits.js (documented booter capability words BARE_OS_KERNEL_FEATURES_STOCK_WORD_*; BARE_OS_KERNEL_FEATURE_BITS_DOC — see source; surfaced in /proc/bare_os_features and /proc/bare_os/), bare-os-protocol/lib/seed-rpc-methods.js (authoritative bare_os.* RPC name list for kernel_info), bare-os-protocol/protocol-meta.js (BARE_OS_PROTOCOL_PACKAGE_VERSION for the seed handshake).
Consumers
- bare-os-seeder — builds MBR, serves block 0 over the channel, replicates the system Hyperdrive.
- bare-os-booter — parses MBR from
SwarmDisk, opens system drives, uses the same channel on the client side, and can mirror block0plus captured seed RPC snapshots after successful boot and eligibility checks.
Tests
npm test -w bare-os-protocol
Runs brittle-bare against test.js (topic stability, MBR roundtrip, encodings).
Dependencies
b4a, compact-encoding, hypercore-crypto (via constants/topic). No Hyperdrive or Hyperswarm here — this package stays small and testable.
