broker: expand member groups to ancestor paths at drain time (pull model)
- @flexicar message reaches peers in @flexicar/core, @flexicar/output, etc.
- Resolved at drainForMember — no DB changes, fully backward-compatible
- Any depth: flexicar/team/backend also matches @flexicar and @flexicar/team
cli: wire --role all the way through to session config + env
- Config.role field added
- launch.ts stores role in sessionConfig, passes CLAUDEMESH_ROLE env var
- mcp/server.ts includes role in identity string
- manager.ts auto-joins groups from config on WS connect (--groups flag now works)

Node.js stdout to a pipe is buffered. Without periodic event loop
activity, WS callback → server.notification() → stdout.write() may
not flush until the next I/O event. A 1s setInterval (NOT unref'd)
keeps the event loop ticking so notifications flush immediately.
This is why claude-intercom worked: its 1s HTTP poll kept the event
loop active as a side effect. Claudemesh's passive WS listener let
the event loop settle, causing stdout to buffer indefinitely.

Files: MinIO-backed file sharing built into the broker.
share_file for persistent mesh files, send_message(file:) for
ephemeral attachments. Presigned URLs for download, access
tracking per peer.
Broker infra: MinIO in docker-compose, internal network.
HTTP POST /upload endpoint. WS handlers for get_file,
list_files, file_status, delete_file.
Multi-target: send_message(to:) accepts string or array.
Targets deduplicated before delivery.
Targeted views: MCP instructions teach Claude to send
tailored messages per audience instead of generic broadcasts.

Phase B + C + message delivery status.
State: shared key-value store per mesh. set_state pushes changes
to all peers. get_state/list_state for reads. Peers coordinate
through shared facts instead of messages.
Memory: persistent knowledge with full-text search (tsvector).
remember/recall/forget. New peers recall context from past sessions.
message_status: check delivery status with per-recipient detail
(delivered/held/disconnected).
Multicast fix: broadcast and @group messages now push directly to
all connected peers instead of racing through queue drain.
MCP instructions: dynamic identity injection (name, groups, role),
comprehensive tool reference, group coordination guide.

Phase A of the claudemesh spec. Peers can now join named groups
with roles, and messages route to @group targets.
Broker:
- @group routing in fan-out (matches peer group membership)
- @all alias for broadcast
- join_group/leave_group WS messages + DB persistence
- list_peers returns group metadata
- drainForMember matches @group targetSpecs in SQL
CLI:
- join_group/leave_group MCP tools
- send_message supports @group targets
- list_peers shows group membership
- PeerInfo includes groups array
- Peer name cache for push notifications
Launch:
- --role flag (optional peer role)
- --groups flag (comma-separated, e.g. "frontend:lead,reviewers")
- Interactive wizard for role + groups when flags omitted
- Groups written to session config for broker hello
Spec: SPEC.md added with full v0.2 vision (groups, state, memory)

Write displayName into tmpdir config.json so the MCP server reads
it directly. Env vars from claudemesh launch may not propagate to
MCP child processes spawned by Claude Code. Config file is reliable.

Each WS connection generates its own ed25519 keypair (sessionPubkey)
sent in the hello handshake. The broker stores it on the presence
row and uses it for message routing + list_peers. This gives every
`claudemesh launch` a unique crypto identity without burning invite
uses — member auth stays permanent, session identity is ephemeral.

Remove ALL Payload imports, withPayload wrapper, and (payload)
routes. Blog index + changelog are now static data arrays.
Blog post at /blog/peer-messaging-claude-code is static TSX.
Payload CMS stays as a dev dependency for future local admin
but has zero presence in the production build.

The private setStatus(ConnStatus) conflicted with the public
setStatus("idle"|"working"|"dnd") method, causing TS2393 under strict
typecheck. Rename the private one to setConnStatus and update all
internal call sites.

The push handler previously fell through to base64-decoding the
raw ciphertext whenever decryptDirect() returned null. For direct
(crypto_box) messages that produces garbage binary which surfaces
as garbled bytes in Claude's <channel> reminder. Limit the base64
fallback to legacy broadcast/channel messages (no senderPubkey),
and emit a clearer "⚠ message from <pubkey> failed to decrypt"
warning when direct decryption fails.

WS handshake is now authenticated end-to-end. The broker proves that
every connected peer actually holds the secret key for the pubkey
they claim as identity — not just that they know the pubkey.
wire format change:
{type:"hello", meshId, memberId, pubkey, sessionId, pid, cwd,
timestamp, signature}
where signature = ed25519_sign(canonical, secretKey)
and canonical = `${meshId}|${memberId}|${pubkey}|${timestamp}`
broker verifies on every hello:
1. timestamp within ±60s of broker clock → else close(1008, timestamp_skew)
2. pubkey is 64 hex chars, signature is 128 hex chars → else malformed
3. crypto_sign_verify_detached(signature, canonical, pubkey) → else bad_signature
4. (existing) mesh.member row exists for (meshId, pubkey) → else unauthorized
All rejection paths close the WS with code 1008 + structured error
message + metrics counter increment (connections_rejected_total by
reason).
new modules:
- apps/broker/src/crypto.ts: canonicalHello, verifyHelloSignature,
HELLO_SKEW_MS constant
- apps/cli/src/crypto/hello-sig.ts: matching signHello helper
clients updated:
- apps/cli/src/ws/client.ts: signs hello before send
- apps/broker/scripts/{peer-a,peer-b}.ts (smoke-test): sign hellos
with seed-provided secret keys
new regression tests — tests/hello-signature.test.ts (7):
- valid signature accepted
- bad signature (signed with wrong key) rejected
- timestamp too old rejected (>60s)
- timestamp too far in future rejected (>60s)
- tampered canonical field (different meshId at verify time) rejected
- malformed hex pubkey rejected
- malformed signature length rejected
verified live:
- apps/broker/scripts/smoke-test.sh: full hello+ack+send+push flow
- apps/cli/scripts/roundtrip.ts: signed hello + encrypted message
- 55/55 tests pass

Direct messages between peers are now end-to-end encrypted. The
broker only ever sees {nonce, ciphertext} — plaintext lives on the
two endpoints.
apps/cli/src/crypto/envelope.ts:
- encryptDirect(message, recipientPubkeyHex, senderSecretKeyHex)
→ {nonce, ciphertext} via crypto_box_easy, 24-byte fresh nonce
- decryptDirect(envelope, senderPubkeyHex, recipientSecretKeyHex)
→ plaintext or null (null on MAC failure / malformed input)
- ed25519 keys (from Step 17) are converted to X25519 on the fly via
crypto_sign_ed25519_{pk,sk}_to_curve25519 — one signing keypair
covers both signing + encryption roles.
BrokerClient.send():
- if targetSpec is a 64-hex pubkey → encrypt via crypto_box
- else (broadcast "*" or channel "#foo") → base64-wrapped plaintext
(shared-key encryption for channels lands in a later step)
InboundPush now carries:
- plaintext: string | null (decrypted body, null if decryption failed
OR it's a non-direct message)
- kind: "direct" | "broadcast" | "channel" | "unknown"
MCP check_messages formatter reads plaintext directly.
side-fixes pulled in during 18a:
- apps/broker/scripts/seed-test-mesh.ts now generates real ed25519
keypairs (the previous "aaaa…" / "bbbb…" fillers weren't valid
curve points, so crypto_sign_ed25519_pk_to_curve25519 rejected
them). Seed output now includes secretKey for each peer.
- apps/broker/src/broker.ts drainForMember wraps the atomic claim in
a CTE + outer ORDER BY so FIFO ordering is SQL-sourced, not
JS-sorted (Postgres microsecond timestamps collapse to the same
Date.getTime() milliseconds otherwise).
- vitest.config.ts fileParallelism: false — test files share
DB state via cleanupAllTestMeshes afterAll, so running them in
parallel caused one file's cleanup to race another's inserts.
- integration/health.test.ts "returns 200" now uses waitFullyHealthy
(a 200-only waiter) instead of waitHealthyOrAny — prevents a race
with the startup DB ping.
verified live:
- apps/cli/scripts/roundtrip.ts (direct A→B): ciphertext in DB is
opaque bytes (not base64-plaintext), decrypted correctly on arrival
- apps/cli/scripts/join-roundtrip.ts (full join → encrypted send):
PASSED
- 48/48 broker tests green

broker-client: full WS client with hello handshake + ack, auto-reconnect
with exponential backoff (1s → 30s capped), in-memory outbound queue
(max 100) during reconnect, 500-entry push buffer for check_messages.
MCP tool integration:
- send_message: "slug:target" prefix or single-mesh fast path
- check_messages: drains push buffers across all clients
- set_status: fans manual override across all connected meshes
- set_summary: stubbed (broker protocol extension needed)
- list_peers: stubbed — lists connected mesh slugs + statuses
manager module holds Map<meshId, BrokerClient>, starts on MCP server
boot for every joined mesh in ~/.claudemesh/config.json.
new CLI command: seed-test-mesh injects a mesh row for dev testing.
also fixes a broker-side hello race: handleHello sent hello_ack before
the caller closure assigned presenceId, so clients sending right after
the ack hit the no_hello check. Fix: return presenceId, caller sets
closure var, THEN sends hello_ack. Queue drain is fire-and-forget now.
round-trip verified: two clients, A→B, push received with correct
senderPubkey + ciphertext. 44/44 broker tests still pass.
