feat(broker): port routing + status model from claude-intercom to postgres
Ports the proven claude-intercom broker logic into apps/broker with SQLite → Drizzle/Postgres translation. Core state engine kept verbatim: source-priority writes (hook > manual > jsonl), fresh-gating, TTL sweeper for stuck-working, pending-status race handler, priority delivery gates (now/next/low), Windows path encoding (5-candidate fallback incl. Roberto's H:\Claude → H--Claude rule). New modules: - broker.ts (492 lines): writeStatus, handleHookSetStatus, sweepers, presence lifecycle, message queueing + drainForMember, sourceRank + isHookFresh / isSourceFresh logic, findMemberByPubkey (WS auth hook). - paths.ts (141): cwdToProjectKeyCandidates + findActiveJsonl + inferStatusFromJsonl — JSONL fallback inference for peers without hooks installed or with stale hook signals. - types.ts (111): WS protocol envelopes (hello/send/push/ack/error/ set_status), HookSetStatusRequest/Response, ConnectedPeer view. - index.ts (323): HTTP on BROKER_PORT+1 for /hook/set-status + /health; WebSocket on BROKER_PORT for authenticated peer connections with hello/send/set_status handlers; connections registry; heartbeat ping/pong every 30s; graceful SIGTERM/SIGINT that marks all active presences disconnected. Mesh scoping: every query/mutation includes meshId. Peer identity is split between mesh.member (stable) and mesh.presence (ephemeral). WS hello authenticates by pubkey against mesh.member (signature verify is stubbed — libsodium wiring lands in client-side package later). Broker never sees plaintext: nonce + ciphertext are opaque text fields passed through. Routing happens on targetSpec (pubkey | "#channel" | "tag:xyz" | "*"), resolved against currently-connected peers. Dependencies not installed; no tests run. Verified via static review of imports against @turbostarter/db exports. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

// TODO: port from ~/tools/claude-intercom/broker.ts in step 8
|
||||
//
|
||||
// That implementation carries the battle-tested pieces we'll migrate:
|
||||
// - status_source column (hook > manual > jsonl) + writeStatus rules
|
||||
// - TTL sweeper for stuck-"working" peers
|
||||
// - Pending hook statuses (first-turn race handler)
|
||||
// - /hook/set-status endpoint for Claude Code hook scripts
|
||||
//
|
||||
// The port swaps SQLite prepared statements for Drizzle queries against
|
||||
// the `mesh` pgSchema (see packages/db/src/schema/mesh.ts). All logic
|
||||
// and test patterns are ported verbatim — only the persistence layer
|
||||
// changes.

/**
|

* MeshBroker — core state engine for claudemesh.
|
||||
*
|
||||
* Ported from ~/tools/claude-intercom/broker.ts with the SQLite layer
|
||||
* translated to Drizzle/Postgres against the `mesh` pgSchema. The

||||
* status model (hook > manual > jsonl priority, fresh-gating, TTL
|
||||
* sweeper) and priority delivery logic are kept verbatim — they're the

|
||||
*
|
||||
* Differences from claude-intercom:
|
||||
* - Peer identity is split: mesh.member (stable, mesh-scoped) vs
|
||||
* mesh.presence (ephemeral, one per WS connection).
|
||||
* - Every query/mutation is scoped by meshId.
|
||||
* - Message envelopes are opaque ciphertext (client-side crypto).
