 ### Fase 3g — IPC + bgbash
 **Sumber Rust:** `apps/infrastructure/src/ipc/{frame,protocol,server,client,conn}.rs`, `apps/infrastructure/src/bgbash/{job,control}.rs`
 
-- [ ] `ipc/frame.ts` — length-prefixed framing via `node:net` (kirim/terima bingkai biner)
-- [ ] `ipc/server.ts` + `ipc/client.ts` — Unix socket server + attach client; protocol message (NLJSON/binary)
-- [ ] `bgbash/job.ts` — `BashJob` (pid, output file, log), `spawn_bash_job`
-- [ ] `bgbash/control.ts` — registry job global: `register`, `cancel(job_id)`, `is_running`
-- [ ] Wire `bash` tool `run_in_background` → `spawn_bash_job` + `register`; `bash_kill` → `cancel`
-- [ ] Update `bash_output` untuk baca dari registry/output dir
