Session lifecycle primitives — return shapes, state source, sync vs live. +2. `status-writer.ts` — write API, event/snapshot shape, on-disk format. +3. On-disk layout under `~/.atomic/sessions//` and `~/.atomic/workflows//`. +4. `runtime/orchestrator-entry.ts` — invocation contract, state, control hooks. +5. The workflow panel — components, data shape, re-render triggers, single-attach assumption. +6. CLI plumbing for `atomic workflow` — flag inventory, `runWorkflow` handoff, slot for `--ui-server`. +7. Existing IPC / RPC machinery in the codebase. +8. Whether `vscode-jsonrpc` (or any Node-flavored RPC) is already a dependency. + +## Summary + +**The primitives a `--ui-server` would need already exist as exported, dependency-injectable functions; the new code is mostly a thin transport layer.** Specifically: + +- The seven session primitives (`listSessions`, `getSession`, `getSessionStatus`, `getSessionTranscript`, `stopSession`, `attachSession`, `detachSession`) plus three pane-navigation primitives (`nextWindow`, `previousWindow`, `gotoOrchestrator`) all live in **one file**, `packages/atomic-sdk/src/primitives/sessions.ts`, and share a single `SessionPrimitiveDeps` DI struct. A UI server can re-use them verbatim; no business logic needs porting. +- Workflow state is already persisted to `~/.atomic/sessions//status.json` via an **atomic write-then-rename** pattern in `packages/atomic-sdk/src/runtime/status-writer.ts`. Every `PanelStore` mutation triggers a debounced flush. **The on-disk file is already the canonical state for out-of-process consumers** (`atomic workflow status` reads it). +- The in-process `OrchestratorPanel` exposes a `subscribe(fn)` hook (`packages/atomic-sdk/src/components/orchestrator-panel.tsx:256`) — adding more listeners is the designed extension point. There's no broadcast/RPC infrastructure today, only one disk writer and one React subscription registered. +- **`vscode-jsonrpc` is _not_ a direct dependency** of any atomic package. It exists transitively under `@github/copilot-sdk` but is never imported. The clean-room Bun-native implementation can avoid it without removing anything. +- The codebase already establishes a **house IPC style**: file-based markers under `~/.atomic//` plus `fs.watch()` with polling fallback (zero-CPU when idle, instant wake-up). There is **zero** TCP/Unix-socket/WebSocket/EventEmitter infrastructure in the SDK or CLI today — a clean slate for a new transport. + +**Caveats the spec author must address:** + +- `attachSession()` in `packages/atomic-sdk/src/primitives/sessions.ts:188` is a **blocking** `Bun.spawnSync` with `stdin/stdout: "inherit"`. It cannot be served from inside a JSON-RPC handler — it would freeze the event loop until the user detaches. The spec must either expose `attachSession` as a "spawn-a-helper" method (write a launcher, return its path / pid) or refuse to expose it. +- The orchestrator process **does not handle SIGTERM**, only SIGINT (`packages/atomic-sdk/src/runtime/executor.ts:2374-2375`). When `tmux kill-session` fires (the path that `stopSession` triggers), the process receives SIGHUP with default disposition and dies without writing a final `status.json`. A UI server living in that process would die with it; one living *outside* the orchestrator (e.g. in the parent CLI) would not. +- `getSessionStatus` and `getSessionTranscript` are **disk reads**, not live tmux queries — so they only reflect whatever the orchestrator last flushed. `listSessions` and `getSession` are **live tmux subprocess queries** with no in-process cache; concurrent JSON-RPC clients would each fork their own `tmux list-sessions` subprocess. A request-coalescing cache in front of the server is worth scoping in v1. +- The workflow panel today **assumes one viewer per run**: it owns `process.stdout` of the orchestrator pane. A UI server is not in conflict (it's a separate channel), but spec must be explicit that the server is a *parallel* read/control surface, not a replacement for the panel. + +## Detailed Findings + +### 1. Session lifecycle primitives — `packages/atomic-sdk/src/primitives/sessions.ts` + +All ten primitives live in one file and share a single DI seam. + +**Common DI struct** (`sessions.ts:68-81`): + +```ts +export interface SessionPrimitiveDeps { + isTmuxInstalled: () => boolean; + listAllTmuxSessions: () => readonly TmuxSession[]; + killSession: (id: string) => void; + attachSession: (id: string) => void; + detachClients: (id: string) => void; + nextWindow: (id: string) => void; + previousWindow: (id: string) => void; + selectWindow: (target: string) => void; // target is `:` + readSnapshot: typeof readSnapshot; + sessionsBaseDir: string; // defaults to ~/.atomic/sessions +} +``` + +**The 10 primitives, by state source:** + +| Primitive | sessions.ts line | State source | Sync/live | Returns | +|---|---|---|---|---| +| `listSessions(opts?)` | 142 | live tmux subprocess (`list-sessions -F …__ATOMIC_SESSION_FIELD__…`) + per-session `show-environment` for unparsed agents | sync subprocess | `SessionInfo[]` | +| `getSession(id)` | 157 | same `listAllTmuxSessions()` call as above, then `.find(s => s.name === id)` | sync subprocess | `SessionInfo \| undefined` | +| `getSessionStatus(id)` | 285 | disk: `~/.atomic/sessions//status.json` (no tmux query) | async file read | `WorkflowStatusSnapshot \| null` | +| `getSessionTranscript(id, sessionName)` | 303 | disk: `~/.atomic/sessions///messages.json` (no tmux query) | async file read | `SavedMessage[]` (never `null`) | +| `stopSession(id)` | 170 | runs `tmux kill-session -t ` via `Bun.spawnSync`; swallows errors twice | sync subprocess inside async wrapper | `void` | +| `attachSession(id)` | 188 | runs `tmux attach-session -t ` via `Bun.spawnSync` with `stdin/stdout: "inherit"` — **blocks the calling process until the user detaches** | sync subprocess inside async wrapper | `void` (throws `MissingDependencyError` if no tmux) | +| `detachSession(id)` | 266 | runs `tmux detach-client -s `; never rejects (two nested `catch {}`) | sync subprocess inside async wrapper | `void` | +| `nextWindow(id)` | 222 | `ensureSession(id)` (full `list-sessions` query) → `tmux next-window -t `; throws on missing tmux/missing id | sync subprocess inside async wrapper | `void` | +| `previousWindow(id)` | 234 | symmetrical — `tmux previous-window` | sync subprocess inside async wrapper | `void` | +| `gotoOrchestrator(id)` | 250 | `ensureSession(id)` → `tmux select-window -t ${id}:0` | sync subprocess inside async wrapper | `void` | + +**Export membership** — relevant for what the UI server can re-export to clients: + +| Primitive | `src/index.ts` (root) | `src/workflows/index.ts` | +|---|---|---| +| `listSessions` | line 97 | line 104 | +| `getSession` | line 98 | line 105 | +| `stopSession` | line 99 | line 106 | +| `attachSession` | line 100 | line 107 | +| `getSessionStatus` | line 105 | line 108 | +| `getSessionTranscript` | line 106 | line 109 | +| `detachSession` | line 101 | **not exported** | +| `nextWindow` | line 102 | **not exported** | +| `previousWindow` | line 103 | **not exported** | +| `gotoOrchestrator` | line 104 | **not exported** | + +The workflows-barrel comment at `workflows/index.ts:8-10` states explicitly: "Tmux helpers and other runtime utilities are intentionally NOT re-exported — they are private to the SDK and the atomic CLI." + +**Behavioral notes for the spec:** + +- `listSessions` / `getSession` / `nextWindow` / `previousWindow` / `gotoOrchestrator` each fork at least one `Bun.spawnSync` per call. **No in-process cache.** Concurrent RPC clients will each fork independently. A request-coalescing layer (e.g. 100ms debounce) is the obvious cache shape. +- `getSessionStatus` / `getSessionTranscript` are disk-only — cheap, idempotent, safe to call concurrently. They reflect whatever the orchestrator last flushed. +- `stopSession` and `detachSession` swallow all errors. Idempotent and safe. +- `attachSession` cannot be served from a JSON-RPC handler — it blocks. Options: (a) refuse to expose, (b) expose a derivative method that returns the `tmux attach-session -t ` argv as a string for the client to invoke locally, (c) spawn a detached helper process. + +### 2. `status-writer.ts` — atomic snapshot, not event stream — `packages/atomic-sdk/src/runtime/status-writer.ts` + +**Important framing correction:** the file does not write a stream of `StatusEvent`s. There is no discriminated union of events. It writes a **single `WorkflowStatusSnapshot` JSON document**, completely rewritten on every change, via atomic write-then-rename. + +**Public API:** + +| Export | Line | Signature | +|---|---|---| +| `STATUS_FILE_NAME` (`"status.json"`) | 15 | constant | +| `WorkflowOverallStatus` | 18-22 | `"in_progress" \| "error" \| "completed" \| "needs_review"` | +| `WorkflowStatusSession` | 25-32 | per-stage record | +| `WorkflowStatusSnapshot` | 38-54 | the persisted document | +| `StatusWriterInputs` | 60-69 | input to `buildSnapshot` | +| `deriveOverallStatus(input)` | 84-96 | computes `overall` from sessions list | +| `buildSnapshot(input, now?)` | 99-127 | pure builder | +| `statusFilePath(sessionDir)` | 130-132 | `join(sessionDir, "status.json")` | +| `writeSnapshot(sessionDir, snapshot)` | 140-153 | atomic write-then-rename | +| `readSnapshot(sessionDir)` | 160-172 | read + JSON.parse + isSnapshot guard | +| `workflowRunIdFromTmuxName(name)` | 193-201 | parses 8-hex suffix from `atomic-wf---` | + +**Snapshot shape** (`status-writer.ts:38-54`): + +```ts +export interface WorkflowStatusSnapshot { + schemaVersion: 1; + workflowRunId: string; + tmuxSession: string; + workflowName: string; + agent: string; + prompt: string; + overall: WorkflowOverallStatus; + completionReached: boolean; + fatalError: string | null; + updatedAt: string; // ISO-8601 + sessions: WorkflowStatusSession[]; +} +``` + +**Per-session shape** (`status-writer.ts:25-32`): + +```ts +export interface WorkflowStatusSession { + name: string; + status: SessionStatus; // 7-variant union from components/orchestrator-panel-types.ts:3 + parents: string[]; + error?: string; + startedAt: number | null; + endedAt: number | null; +} +``` + +`SessionStatus` union (`packages/atomic-sdk/src/components/orchestrator-panel-types.ts:3`): +`"pending" | "running" | "complete" | "error" | "awaiting_input" | "offloaded" | "resuming"`. + +**On-disk format:** + +- Path: `~/.atomic/sessions//status.json`. +- `JSON.stringify(snapshot, null, 2)` — pretty-printed, fully rewritten on every update. **Not append-only JSONL.** +- Atomicity (`status-writer.ts:144-149`): write to `status.json.tmp-`, then `rename(2)` to `status.json`. POSIX rename is atomic on the same filesystem; readers see either the prior full snapshot or the new one, never partial JSON. **No `fsync`.** Errors are silently swallowed. + +**Writers — exactly two callsites in production code, both in `executor.ts`:** + +1. **Debounced subscription callback** (`packages/atomic-sdk/src/runtime/executor.ts:2330-2348`): + ```ts + let snapshotPending = false; + const persistSnapshot = (): void => { + if (snapshotPending) return; + snapshotPending = true; + queueMicrotask(() => { + snapshotPending = false; + const snap = panel.getSnapshot(); + void writeSnapshot(sessionsBaseDir, buildSnapshot({ + workflowRunId, tmuxSession: tmuxSessionName, ...snap, + })); + }); + }; + const unsubscribePanel = panel.subscribe(persistSnapshot); + persistSnapshot(); // seed the file before any stage + ``` + Triggered on every `PanelStore` mutation (stage start/end/error/HIL/completion). The `queueMicrotask` debounce collapses bursts into one write per event-loop turn. + +2. **Final shutdown write** (`executor.ts:2357-2364`): + ```ts + void writeSnapshot(sessionsBaseDir, buildSnapshot({ + workflowRunId, tmuxSession: tmuxSessionName, ...panel.getSnapshot(), + })); + ``` + Called from `shutdown(exitCode)` after `unsubscribePanel()`. Runs on clean exit *and* SIGINT-triggered exit, but **not on SIGHUP** (which is what `tmux kill-session` ultimately delivers). + +**Readers — three production callsites:** + +1. `readSnapshot` itself (`status-writer.ts:160-172`). One-shot disk read, no watcher. +2. `packages/atomic/src/commands/cli/workflow-status.ts:84-131` — used by `atomic workflow status`. One-shot read on user/agent invocation. +3. `packages/atomic-sdk/src/primitives/sessions.ts:285-291` — used by `getSessionStatus`. One-shot read on each call. + +**No file watchers exist on `status.json`.** All readers poll/read on demand. + +**Lifecycle:** Created at orchestrator start (the `persistSnapshot()` seed call before any stage). Rewritten on every panel mutation and on shutdown. **Never deleted** — `~/.atomic/sessions//` accumulates indefinitely. There is no reaper or TTL. + +### 3. On-disk layout under `~/.atomic/` + +The runtime touches **far more** than `sessions/` and `workflows/`. Full tree: + +``` +~/.atomic/ +├── sessions/ +│ ├── / # 8-hex from crypto.randomUUID().slice(0,8) +│ │ ├── status.json # WorkflowStatusSnapshot (atomic rename-write) +│ │ ├── metadata.json # workflow-level: name, agent, prompt, cwd, startedAt +│ │ ├── orchestrator.sh|.ps1 # launcher script written by executor.ts:780 +│ │ ├── orchestrator.log # stderr of orchestrator process +│ │ ├── telemetry.jsonl # appended events (mode 0o600) +│ │ └── -/ # per-stage subdir +│ │ ├── metadata.json # stage: name, description, agent, paneId, startedAt +│ │ ├── messages.json # SavedMessage[] from s.save() +│ │ ├── inbox.md # rendered messages for human review +│ │ └── error.txt # only if stage failed +│ └── chat/ +│ └── atomic-chat--.sh|.ps1 # chat-mode launcher (deleted post-attach) +├── workflows/ +│ └── / +│ └── index.ts # atomic-managed Mode 1 workflow definition +├── tmp/ +│ └── - # ephemeral temp via atomic-temp.ts +├── runtime/ +│ └── / +│ └── tmux.conf # materialized from bunfs (compiled binary) +├── bin/ # Windows-only psmux/pmux install +├── claude-stop/ # turn-completion marker +├── claude-queue/ # next-prompt queue file +├── claude-release/ # session-end signal +├── claude-hil/ # human-in-loop marker +├── claude-pid/ # workflow PID for liveness detection +├── claude-ready/ # session-ready signal +├── claude-inflight/ +│ ├── / # subagent lifecycle marker +│ └── .session-roots/ # nested-subagent → root mapping +├── settings.json # global registry + provider config +└── .synced-version # installer marker +``` + +**Two paths matter most to the UI server:** + +1. **`~/.atomic/sessions//status.json`** — the only out-of-process state channel that's already designed for cross-process reading. The UI server should fan it out over the wire. +2. **`~/.atomic/sessions//-/messages.json`** — per-stage transcripts; also designed for cross-process reading via `getSessionTranscript`. + +**Observation:** `runId` resolution is one-way — given a tmux session name `atomic-wf---`, you can extract the 8-hex `runId` via `workflowRunIdFromTmuxName` (`status-writer.ts:193-201`). Going the other direction (runId → tmux session name) requires a `list-sessions` query. The UI server should standardize on **tmux session name** as the addressable identifier in JSON-RPC method params, since that's what the SDK primitives accept. + +### 4. `runtime/orchestrator-entry.ts` — thin dispatcher; real state lives in `executor.ts` + +`orchestrator-entry.ts` itself is stateless.

Sets production telemetry sink, `process.chdir(cwd)`. +3. Reads `~/.atomic/settings.json` + project `.atomic/settings.json` for provider overrides. +4. `OrchestratorPanel.create(...)` initializes OpenTUI and the React tree. +5. `panel.subscribe(persistSnapshot)` + immediate seed write. +6. Wires SIGINT → `shutdown(1)` (`executor.ts:2374-2375`). **Does not wire SIGTERM** — comment at line 2372 says "SIGTERM and other signals are handled by OpenTUI's exitSignals." +7. Builds `OffloadManager`, `SharedRunnerState`, `WorkflowContext`. +8. Writes `~/.atomic/sessions//metadata.json`. +9. **`await Promise.race([definition.run(workflowCtx), abortPromise])`** — main blocking await. +10. On normal completion: `panel.showCompletion(...)` → `await panel.waitForExit()` → `shutdown(0)`. +11. On `WorkflowAbortError`: `shutdown(0)`. +12. On other error: `panel.showFatalError(message)` → `await panel.waitForExit()` → `shutdown(1)`. + +**Control hooks already wired:** + +- **SIGINT** → `shutdown(1)` (writes final `status.json`, kills tmux session). +- **Keyboard `q` inside OpenTUI** → `panel.waitForAbort()` resolves → `WorkflowAbortError` thrown. +- **No SIGTERM handler.** SIGTERM hits OpenTUI's default handler, which terminates without atomic's cleanup. +- **No control file/socket/FIFO/sentinel.** No mechanism for an external process to ask "stop", "next-pane", "go-to-orchestrator-pane" via IPC. All control flows through signals or the keyboard. + +**Stop mechanics:** `stopSession(id)` → `tmux kill-session -t `. tmux kills the orchestrator pane → orchestrator process receives **SIGHUP**. There is no SIGHUP handler; the process dies with default disposition. **`shutdown()` is not called in this path**, so the final `status.json` write is skipped. The status snapshot will reflect the last debounced flush (which may or may not include "completed" — likely "in_progress" forever for an externally-killed run). + +**Status writes are tied to panel mutations.** Every `PanelStore` mutation triggers `persistSnapshot`. Mutations include `addSession`, `backgroundTaskStarted/Finished`, `sessionSuccess`, `sessionError`, `sessionAwaitingInput`, `sessionResumed`, `showCompletion`, `showFatalError`. See list at `executor.ts:1936-1953`. + +### 5. The workflow panel — `packages/atomic-sdk/src/components/` + +**Library:** OpenTUI exclusively. `@opentui/core` (`createCliRenderer`, `KeyEvent`, `ScrollBoxRenderable`, `TextareaRenderable`) + `@opentui/react` (`createRoot`, `useKeyboard`, `useTerminalDimensions`, `useRenderer`). Confirmed by `workflow-picker-panel.tsx:1` JSX pragma and `orchestrator-panel.tsx:7-8` imports. + +**Two top-level panel classes (different lifecycles):** + +- `OrchestratorPanel` (`orchestrator-panel.tsx`) — live workflow view that runs inside the orchestrator pane during workflow execution. +- `WorkflowPickerPanel` (`workflow-picker-panel.tsx`) — pre-run picker, blocks the CLI until the user confirms or cancels. +- A third path, the **attached footer** (`tui/attached-statusline.tsx`), uses React purely as a JSX→tmux-format-string compiler — it sets `@atomic-*` tmux user-options once and exits. No live renderer. + +**Component tree (orchestrator panel):** + +``` +OrchestratorPanel +└── createRoot(renderer).render( + StoreContext.Provider(PanelStore) + ThemeContext.Provider(GraphTheme) + TmuxSessionContext.Provider(string) + OffloadManagerContext.Provider(OffloadManager | null) + ErrorBoundary + SessionGraphPanel + ├── Header (CountBadge × N) + ├── (Edge × N + NodeCard × N) + ├── CompactSwitcher? (when "/" pressed) + └── ToastStack (ToastCard × N) + ) +``` + +**State source — `PanelStore`** (`orchestrator-panel-store.ts:20`): + +```ts +class PanelStore { + version = 0; + workflowName = ""; + agent = ""; + prompt = ""; + sessions: SessionData[] = []; // <— main state + completionInfo: { workflowName: string; transcriptsPath: string } | null = null; + fatalError: string | null = null; + completionReached = false; + exitResolve: (() => void) | null = null; + abortResolve: (() => void) | null = null; + backgroundTaskCount = 0; + viewMode: ViewMode = "graph"; // "graph" | "attached" | "resuming" + activeAgentId = ""; + toasts: ToastEntry[] = []; + private listeners = new Set(); +} +``` + +The store is **the only data source the panel consumes**. It does not call `listSessions()`, `getSessionStatus()`, or watch any file. The executor mutates the store directly via imperative methods (`panel.sessionStart(name)`, `panel.sessionSuccess(name)`, `panel.sessionError(name, msg)`, …); each mutation calls `this.emit()` which increments `version` and notifies all listeners. + +**Re-render triggers:** + +| Trigger | Source | +|---|---| +| `PanelStore.emit()` → `useSyncExternalStore` | every imperative mutation method | +| 60ms `setInterval` pulse animation | `session-graph-panel.tsx:128-135` (only when any session is `running`/`awaiting_input`) | +| 500ms `setInterval` tmux poll for `viewMode` | `session-graph-panel.tsx:397-455` (`tmux display-message -t -p '#{window_index} #{window_name}'`) | +| `setTimeout` toast auto-dismiss | `orchestrator-panel-store.ts:189-196` | +| `OrchestratorPanel.attachOffloadManager()` | `orchestrator-panel.tsx:276-279` (one-time) | + +**Single-attach assumption — confirmed.** `createCliRenderer` (`orchestrator-panel.tsx:108-111`) yields a single renderer tied to `process.stdout`/`process.stdin` of the orchestrator pane. tmux multiplexes the PTY to multiple viewers, but the React renderer and `PanelStore` know nothing about additional clients. **One `PanelStore`, one render loop.** + +**Critical extension point for the UI server** — `OrchestratorPanel.subscribe(fn)` (`orchestrator-panel.tsx:256`): + +> The store's `listeners` `Set` already supports multiple subscribers. Today only two consumers register: the React `useSyncExternalStore` subscription and the `persistSnapshot` disk writer. **The `subscribe()` method is the designed extension point for additional state consumers.** A UI server living in the orchestrator process can attach a third subscriber that fans out to N JSON-RPC clients with zero changes to the store. + +### 6.

This is a clean slate. + +## Open Questions for the spec author + +1. **Process scope of the UI server.** Two options: + - (a) **In-orchestrator**: spawn the server inside `runOrchestrator()` (`executor.ts:2290+`), attach it as a third subscriber to `panel.subscribe(...)`, tear down in `shutdown()`. Pro: zero polling, push-based events, identical state to the panel. Con: dies on SIGHUP from `tmux kill-session`; cannot serve a workflow whose orchestrator process is gone. + - (b) **Out-of-process**: a separate Bun process spawned by the parent CLI (`executeWorkflow` at `executor.ts:659+`) that watches `~/.atomic/sessions//status.json` via `fs.watch` and re-emits to clients. Pro: survives orchestrator death, can serve completed/historical runs. Con: latency of file-watch round-trip; needs its own lifecycle management. +2. **Identifier in JSON-RPC params.** Tmux session name (`atomic-wf---`) vs. bare `runId`. The SDK primitives accept tmux session names; converting requires an extra `list-sessions` call. Recommend tmux session name. +3. **`attachSession` exposure.** Cannot run inside an RPC handler (blocks). Three options: + - Refuse to expose. + - Expose `getAttachCommand(id)` returning the argv string, let client invoke locally. + - Expose `spawnAttachHelper(id)` that detaches a child process and returns its PID. +4. **Transport defaults.** Unix socket (`~/.atomic/sessions//ui.sock`) is recommended for security and zero-port-collision. TCP only when `--ui-server=` is given explicitly. Spec must define both code paths. +5. **Authn/authz for TCP mode.** Unix socket is filesystem-permission-scoped; TCP isn't. Token? Localhost-only bind? `Authorization` header? Spec needs a story. +6. **Wire protocol versioning.** Mirror the precedent at `sdk-protocol-version.json` from Copilot's runtime — single source of truth that clients can version-gate. +7. **Live event stream vs. pull-only.** + - Pull-only v1: clients call `session/list`, `session/status`, `session/transcript` on demand. + - Push v1.5: server emits `panel.update` notifications when `PanelStore` mutates (in-orchestrator scope only). + - Push for out-of-process scope: server fans out from a `fs.watch(status.json)` loop. +8. **Backpressure / fairness when multiple clients connect to one run.** Each subscription holds a reference to the live `PanelStore` listeners set; teardown on disconnect is critical to avoid leaks. +9. **Behavior when `--ui-server` is passed but the workflow runs `--detach`.** Detached mode means the parent CLI returns immediately; the orchestrator continues in tmux. The UI server should outlive the parent CLI (ergo: in-orchestrator scope, or a separate background process). +10. **Behavior when the orchestrator pane is offloaded** (`offloaded` / `resuming` `SessionStatus`). The UI server should expose this state as it appears in the snapshot — clients render it without the server needing extra logic. + +## Related Research + +- `specs/2026-05-08-workflow-pane-offload-and-resume.md` — pane offload state machine +- `research/docs/2026-04-10-tmux-ux-implementation-guide.md` — tmux dispatcher implementation +- `research/docs/2026-03-25-workflow-interrupt-resume-bugs.md` — session lifecycle hazards +- `research/docs/2026-01-31-atomic-current-workflow-architecture.md` — pre-rewrite architecture context diff --git a/specs/2026-05-09-ui-server-bun-native.md b/specs/2026-05-09-ui-server-bun-native.md new file mode 100644 index 000000000..44beea13b --- /dev/null +++ b/specs/2026-05-09-ui-server-bun-native.md @@ -0,0 +1,647 @@ +# atomic 2.0: daemonized runtime, JSON-RPC control surface, tmux-free + +| Document Metadata | Details | +| ---------------------- | ------------------------------------------------------------------------------ | +| Author(s) | alexlavaee | +| Status | Draft (WIP) | +| Team / Owner | atomic | +| Created | 2026-05-09 | +| Last Updated | 2026-05-09 | +| Source Research | [`research/docs/2026-05-09-ui-server-architecture.md`](../research/docs/2026-05-09-ui-server-architecture.md) | +| Branch | `fix/issue-898-opentui-runtime-plugin` | +| Wire protocol | JSON-RPC 2.0 with LSP `Content-Length` framing via `vscode-jsonrpc` | +| Process model | Per-user singleton daemon, **no tmux**, OpenTUI-native multi-pane | +| Scope | Major version bump (atomic 2.0) — breaking change relative to 1.x runtime | + +--- + +## 1. Executive Summary + +This RFC proposes **atomic 2.0**: a fundamental restructuring of the atomic runtime. The atomic CLI becomes a **per-user singleton daemon** (`atomic --ui-server`) that exposes the entire workflow control surface — discovery, dispatch, lifecycle, panel state — as one JSON-RPC 2.0 protocol over LSP-framed sockets. The SDK (`@bastani/atomic-sdk`) becomes a thin client that auto-spawns and connects to the daemon; the atomic CLI binary ships **with the SDK** via platform-binary `optionalDependencies` (the same pattern Claude Agent SDK uses for the `claude` binary). + +The current tmux dependency is **removed entirely**. Workflow agent processes (Claude Code, Copilot CLI, OpenCode) become PTY-attached subprocess clients of the daemon, supervised by daemon-owned `bun-pty` allocators. The workflow panel detaches from any orchestrator pane process and becomes a daemon-state view that any subscribed client can render natively in OpenTUI. The four hidden argv subcommands (`_orchestrator-entry`, `_emit-workflow-meta`, `_atomic-run`, `_cc-debounce`) all disappear — replaced by RPC methods on the daemon. Boot context flows over RPC, not env vars. Detach/reattach become first-class JSON-RPC concepts (client disconnects, daemon retains state, another client connects). Multi-attach works for free. + +This is a major version increment. The migration is non-incremental: 1.x and 2.0 cannot coexist on the same machine without isolation. The payoff is structural — atomic becomes self-contained (Bun + OpenTUI only, zero external runtime deps), SDK-only users get auto-install through the daemon, the protocol surface is unified end-to-end, and Windows behavior is no longer hostage to the third-party psmux fork. + +--- + +## 2. Context and Motivation + +### 2.1 Current State (the 1.x tmux runtime) + +The 1.x architecture spreads workflow control across three layers: + +1. **In-process** — `OrchestratorPanel` (OpenTUI React tree) inside the orchestrator pane, owning `process.stdout`, mutated by imperative `PanelStore` calls ([`orchestrator-panel.tsx:108-111`](../packages/atomic-sdk/src/components/orchestrator-panel.tsx)). +2. **On-disk** — `~/.atomic/sessions//status.json`, atomically rename-written on every store mutation ([`status-writer.ts:140-153`](../packages/atomic-sdk/src/runtime/status-writer.ts)). +3. **SDK primitive functions** — ten functions in [`primitives/sessions.ts`](../packages/atomic-sdk/src/primitives/sessions.ts), each shelling out to tmux subprocesses or reading disk on demand. + +Process supervision goes through tmux: each workflow run creates a `tmux new-session -L atomic`, each stage gets its own `new-window`, agent CLIs run inside those windows with their own PTYs allocated by tmux. Hidden argv subcommands (`_orchestrator-entry`, `_atomic-run`, `_emit-workflow-meta`, `_cc-debounce`) bridge between tmux's shell-argv invocation model and atomic's logic. ([Research §3-§7](../research/docs/2026-05-09-ui-server-architecture.md)) + +### 2.2 The Problem + +**Hidden architectural debt.** The four hidden subcommands exist because tmux speaks shell argv, not RPC. Every "how does atomic talk to itself?" question lands at "go look at the argv contract." The contracts are scattered across `executor.ts:780`, `tmux.ts:262`, `claude-stop-hook.ts`, `claude-inflight-hook.ts`. + +**Tmux-imposed costs:** + +- **Cross-platform fragility.** tmux is Linux/macOS-native; Windows runs psmux, a third-party fork. The publish pipeline ships separate Windows binaries because of this. `auto-sync.ts:106,110` and `lib/spawn.ts:497` exist solely to install/upgrade tmux variants per platform. +- **`_cc-debounce`** exists because tmux hooks fundamentally exec shell commands; we cannot debounce Claude Code redraws via in-process logic without a tmux-shell-out callback. +- **Single-attach assumption** baked into the panel. tmux multiplexes the PTY but the React reconciler is single-instance; multiple clients cannot render the panel concurrently. +- **`attachSession` is blocking** ([`sessions.ts:188`](../packages/atomic-sdk/src/primitives/sessions.ts)) — `Bun.spawnSync` with inherited stdio, so it cannot be served from any RPC handler without freezing the event loop. +- **Detach/reattach** is a tmux concept; consumers without tmux access (CI, IDE plugins, headless cloud runners) cannot observe a running workflow without scraping `status.json`. + +**SDK-only users miss auto-install.** `runWorkflow` self-execs into an SDK-bundled dispatcher that does *not* run `auto-sync.ts`. SDK-only users hit `MissingDependencyError` if tmux is missing — they install it manually. Claude Agent SDK doesn't have this problem because it ships the `claude` binary as a platform-package. + +**Programmatic control is poll+exec.** Today, observing a running workflow means calling `getSessionStatus(id)` repeatedly (one disk read per call). There is no push channel. IDE plugins, dashboards, CI scripts all have to poll. + +### 2.3 Why now + +The architectural pattern — long-running per-user daemon, JSON-RPC over LSP framing, PTY-managed agent subprocess clients, no tmux — is established and well-understood. The Claude Agent SDK ships platform binaries as `optionalDependencies`. `vscode-jsonrpc` is the LSP ecosystem standard for the wire format. PTY libraries for Bun matured to production-ready in 2025. OpenTUI already supports the layout primitives needed for multi-pane rendering. Every dependency we need exists; what's missing is the integration. + +Atomic shipping this now consolidates the four scattered IPC surfaces (in-process panel, on-disk status, SDK primitives, hidden argv contracts) into one. It removes a dependency that costs more than it earns. And it lets the SDK consumer experience match what Claude Agent SDK has had since 0.1. + +--- + +## 3. Goals and Non-Goals + +### 3.1 Functional Goals + +- [ ] `atomic --ui-server` starts a per-user singleton daemon.

Multi-client subscription supported. +- [ ] **tmux dependency removed entirely.** `packages/atomic-sdk/src/runtime/tmux.ts`, `attached-footer.ts`, `lib/spawn.ts:ensureTmuxInstalled`, the auto-sync tmux installer, and the psmux Windows pipeline all delete. +- [ ] **Zero hidden subcommands.** No `_orchestrator-entry`, `_emit-workflow-meta`, `_atomic-run`, `_cc-debounce` in the CLI. Internal-only argv flags (e.g. `--render-pane=` for the OpenTUI panel client) are documented as part of the public CLI surface. +- [ ] Process supervision moves into the daemon. Agent CLIs (Claude Code, Copilot CLI, OpenCode) spawn as `bun-pty`-allocated PTY subprocess clients of the daemon. +- [ ] OpenTUI panel becomes a daemon-protocol client. State flows from daemon → panel via `panel/update`. Input flows from panel → daemon via `pane/sendInput`. +- [ ] Detach/reattach: client disposes connection → daemon retains state → another client connects → fresh `panel/get` + new subscription. No daemon-side change required for either side of the cycle. +- [ ] Multi-attach: N clients subscribe to the same run; each renders independently in their own OpenTUI process. +- [ ] Identical cross-platform behavior. The daemon's process supervisor is the same on Linux, macOS, and Windows. No psmux. No platform-specific tmux quirks. +- [ ] Boot context for spawned panel clients flows over RPC, not env vars. Panel client receives `--daemon-endpoint=` + `--token=` + `--run-id=` argv flags (public CLI surface). +- [ ] Wire-protocol versioning via `packages/atomic-sdk/sdk-protocol-version.json` + a `protocol/getVersion` RPC. +- [ ] Tests exercise the JSON-RPC dispatcher via in-memory `MessageConnection` pairs (no real socket); integration tests exercise the daemon end-to-end with a fake project tree. + +### 3.2 Non-Goals (Out of Scope for atomic 2.0) + +- [ ] **Cross-host attach.** Daemon binds to `127.0.0.1` only. No `0.0.0.0`, no TLS, no remote auth. Cloud-runner integrations must SSH-port-forward. +- [ ] **Multi-user daemon.** One daemon per user. Multi-user machines run one daemon per UID. +- [ ] **Backward compatibility with running 1.x sessions.** Atomic 2.0 cannot reattach to a tmux session created by atomic 1.x. Users must let 1.x sessions complete before upgrading. +- [ ] **Migration of `~/.atomic/sessions//` from 1.x.** 2.0's daemon registry initializes empty. 1.x session artifacts on disk are ignored (operators can `rm -rf` them). +- [ ] **An IDE plugin or web dashboard.** Those are downstream consumers of the protocol, not in this RFC's scope. A minimal Bun `examples/ui-server-client/` is the only reference client that ships. +- [ ] **Browser-side renderer.** OpenTUI is terminal-only. Browser dashboards must use the JSON-RPC protocol over a separate transport (HTTP gateway is a future direction). +- [ ] **A `_cc-debounce` analog.** Without tmux hooks, the redraw signal arrives directly from the agent SDK. No debouncing primitive needed. + +--- + +## 4.

Clients subscribe; the daemon broadcasts. Agents are children of the daemon, not peers. + +### 4.2 Architectural Pattern + +**Daemon-with-clients over JSON-RPC.** + +- **Daemon state.** Every running workflow's `PanelStore` lives in the daemon's memory. The disk writer (`status.json`) is a daemon-side persistence shadow, not the canonical state. +- **Process supervisor.** The daemon owns every agent subprocess. Each gets a PTY via `bun-pty`. The daemon reads from each PTY into a per-stage scrollback buffer and forwards client-supplied input. Subprocess death → daemon emits `panel/update` → all subscribers see the transition. +- **Clients are renderers.** The OpenTUI panel that the user sees when they type `atomic workflow` is a client of the daemon — same protocol as any IDE plugin or CI script. There is no privileged "owns the orchestrator" client. +- **No tmux.** Multi-pane visualization happens inside the OpenTUI client's render tree. Detach/reattach is "client disconnects, daemon retains state, new client connects." Cross-platform behavior is defined entirely by `bun-pty` + OpenTUI, both of which are Bun-native. + +### 4.3 Key Components + +| Component | Responsibility | New / Modified | +| --- | --- | --- | +| `atomic --ui-server` daemon | Long-lived per-user process.

Subscribes to `panel/update`. Renders the graph. Handles keyboard, forwards to daemon. | Major rewrite of `packages/atomic-sdk/src/components/orchestrator-panel.tsx` | +| PTY widget | New OpenTUI component that renders an agent stage's PTY scrollback inline in the panel. Forwards input on focus. | New, `packages/atomic-sdk/src/components/pty-pane.tsx` | +| `vscode-jsonrpc` direct dep | Promote from transitive (via `@github/copilot-sdk`) to direct dep of `@bastani/atomic-sdk`. Pin to `^8.2.1`. | Modification, `packages/atomic-sdk/package.json` | +| `bun-pty` direct dep | New dep on a Bun-native PTY library (`bun-pty`); `node-pty` fallback if a target platform proves unstable. | Modification, `packages/atomic-sdk/package.json` | +| Platform-binary `optionalDependencies` | `@bastani/atomic-sdk` declares every variant of `@bastani/atomic-${platform}-${arch}` as optional.

Client opens `net.connect({ host: "127.0.0.1", port })`. +2. Server's `net.createServer` accepts; attaches `MessageConnection` via `createMessageConnection(new StreamMessageReader(socket), new StreamMessageWriter(socket))`; calls `conn.listen()`. +3. Connection starts unauthenticated. Only `protocol/getVersion` and `connect` succeed. +4. Client calls `connect({ token, clientName })`. Token is compared against `process.env.ATOMIC_UI_SERVER_TOKEN` with `timingSafeEqual`. If env var unset, the daemon logged a warning at start and accepts any value. `clientName` is mandatory. +5. After `connect`, client calls any method. +6. Daemon shutdown: emits `server/closing` to every connection, waits 100ms for buffered writes, calls `MessageConnection.dispose()` per connection, then `net.Server.close()`. + +### 5.2 Daemon Lifecycle and Discovery + +**Singleton enforcement.** At `daemon.start()`: +1. Read `~/.atomic/daemon.endpoint.json` if it exists. +2. If present, attempt `net.connect` on the listed `port`. If connect succeeds and `protocol/getVersion` returns sanely, exit with the existing endpoint info — another daemon is already running. +3. If connect fails (ECONNREFUSED, EHOSTUNREACH, parse error), the file is stale; unlink it and proceed. +4. Bind `net.createServer().listen(0, "127.0.0.1")` (kernel-assigned port). +5. Generate `connectionToken` if `ATOMIC_UI_SERVER_TOKEN` is unset (or use the env-supplied value). +6. Write `~/.atomic/daemon.endpoint.json` with mode `0o600`: + ```jsonc + { + "port": 53247, + "host": "127.0.0.1", + "pid": 4711, + "startedAt": "2026-05-09T19:52:28.000Z", + "atomicVersion": "2.0.0", + "protocolVersion": "1.0.0" + } + ``` +7. Trap SIGTERM, SIGINT, and SIGHUP. On any of these: emit `server/closing` to every client, drain (100ms), unlink the endpoint file, exit cleanly. +8. Trap unhandled exceptions; log to `~/.atomic/daemon.log`; emit `server/closing` with `reason: "fatal"`; exit 1. + +**SDK auto-spawn.** `runWorkflow({...})` resolution path: +1. Try to read `~/.atomic/daemon.endpoint.json`. If present, attempt connection. +2. If absent or unreachable: spawn `Bun.spawn([atomicBinaryPath, "--ui-server"], { stdio: ["ignore", "ignore", "ignore"], detached: true })`. +3. Poll `~/.atomic/daemon.endpoint.json` every 50ms for up to 5s; return `MissingDependencyError` after timeout. +4. Connect, send `connect({ token, clientName: "@bastani/atomic-sdk" })`, return the `MessageConnection`. + +**Token sourcing for SDK.** The SDK reads `process.env.ATOMIC_UI_SERVER_TOKEN`. If set in the SDK consumer's env, it is forwarded to the spawned daemon via `Bun.spawn({ env: process.env })`. If unset, the daemon spawns without auth (loopback-only — same trust model as a local dev server). + +**`atomicBinaryPath` resolution.** +1. `process.env.ATOMIC_BINARY` (override). +2. `require.resolve(\`@bastani/atomic-${platform}-${arch}/bin/atomic\`)` — the bundled platform binary. +3. `Bun.which("atomic")` — globally-installed CLI on PATH. +4. Fail with `MissingDependencyError("@bastani/atomic")`. + +### 5.3 Process Supervisor (replaces tmux) + +The supervisor is the heart of the architectural change. It owns every agent subprocess via `bun-pty` and exposes them to the daemon's RPC layer. + +**Per-stage state:** + +```ts +interface SupervisedStage { + runId: string; + stageName: string; + agent: AgentType; + pty: import("bun-pty").IPty; // PTY handle: write(), kill(), onData, onExit + scrollback: RingBuffer; // bounded byte buffer (default 4 MiB) + scrollbackHead: number; // monotonically increasing offset + outputSubscribers: Set; // clients receiving pane/output + startedAt: number; + endedAt: number | null; + exitCode: number | null; +} +``` + +**Spawn flow** (called from inside a workflow stage's callback via the daemon-resident `WorkflowContext`): + +```ts +const pty = bunPty.spawn(agentBinary, args, { + name: "xterm-256color", + cols: 120, rows: 40, + cwd: projectRoot, + env: { ...process.env, ...stageEnv }, +}); +pty.onData((data) => { + this.scrollback.append(data); + this.scrollbackHead += data.length; + for (const sub of this.outputSubscribers) { + void sub.sendNotification("pane/output", { + runId, stageName, data, offset: this.scrollbackHead, + }); + } +}); +pty.onExit(({ exitCode, signal }) => { + this.endedAt = Date.now(); + this.exitCode = exitCode; + this.broadcast("pane/exit", { runId, stageName, exitCode, signal }); + this.panelStore.sessionEnded(stageName, exitCode === 0 ? "complete" : "error"); +}); +``` + +**Input forwarding** (`pane/sendInput`): supervisor calls `pty.write(data)`. No buffering on the daemon side — the PTY's kernel buffer handles backpressure. + +**Resize**: future. v2.0 ships fixed cols/rows; resize ergonomics are a post-v2.0 polish. + +**Death detection**: `pty.onExit` is the source of truth. No timer-based liveness check. + +### 5.4 OpenTUI Panel as Daemon Client + +The panel deployment changes fundamentally. Today the panel runs in-process inside the orchestrator pane. In 2.0, the panel runs as a separate process: a Bun client of the daemon. + +**When the user types `atomic workflow ...`:** +1. CLI ensures daemon is running (`Daemon.ensureStarted()` — idempotent). +2. CLI calls `workflow/start({...})`, gets `runId`. +3. CLI mounts a panel client: `await PanelClient.mount({ daemonEndpoint, token, runId })`. +4. Panel client connects, subscribes to `panel/update` for the runId, calls `panel/get` for initial state, mounts the OpenTUI tree. +5. Panel client owns the user's terminal stdout/stdin until it returns. +6. On Ctrl+C / `q`: panel disconnects, returns. The daemon retains the run. + +**When the user later runs `atomic workflow attach `:** +1. Connect to daemon, mount a fresh panel client subscribing to that runId. +2. No daemon-side change — the run continued running while no panel was attached. + +**PTY widget.** A new OpenTUI component renders an agent stage's scrollback. On focus, keystrokes get forwarded to `pane/sendInput`. Component lifecycle: +- Mount: subscribe to `pane/output` for `(runId, stageName)`. Call `pane/getScrollback` for the initial buffer. +- Output handler: append `data` at `offset`, scroll to bottom unless user scrolled up. +- Input handler: `pane/sendInput({ data: keystroke })`. +- Unmount: dispose the subscription. + +The panel's outer layout uses OpenTUI's existing graph rendering for the workflow shape, with each `NodeCard` linking to a focusable `PtyPane` for that stage's live agent output. + +**No `attached-footer.ts`.** The footer status surface was a tmux `set-option`-based cross-pane signal. With everything in one OpenTUI process, in-tree state replaces it. + +### 5.5 Detach / Reattach + +Implemented at the connection layer. + +**Detach** = panel client closes its connection. Daemon's `panel/subscribe` cleanup removes the subscriber from the broadcast set. The run continues. + +**Reattach** = new panel client connects, subscribes, calls `panel/get` for the current snapshot, calls `pane/getScrollback` for any stages it wants to render history of. Multiple reattaches simultaneously: all subscribe; all receive notifications. + +**Background runs:** `atomic workflow ... -d` becomes a panel client that calls `workflow/start` and returns immediately without mounting. The run continues; no panel is attached. The user can `atomic workflow attach ` later. + +### 5.6 SDK as Thin Client + +`runWorkflow({ workflow, inputs })` becomes: + +```ts +export async function runWorkflow( + options: RunWorkflowOptions, +): Promise { + const conn = await connectToDaemon(); // §5.2 auto-spawn + const { runId } = await conn.sendRequest("workflow/start", { + source: getSource(options.workflow), + workflowName: getName(options.workflow), + agent: getAgent(options.workflow), + inputs: validateInputs(options.workflow, options.inputs), + }); + if (!options.detach) { + // optional: subscribe and wait for run/ended + // ... or hand back conn for the caller to drive + } + return { runId, daemon: conn }; +} +``` + +`hostLocalWorkflows([wf])` is **deleted from the SDK surface**. The hidden-command-dispatch role goes away entirely. SDK consumers `import` their workflow modules normally and pass the `WorkflowDefinition` to `runWorkflow`; the daemon also imports them when receiving `workflow/start`. Existing 1.x workflow files that call `hostLocalWorkflows([wf])` at the top level **break at import time** under 2.0 — the migration guide instructs authors to remove the call and `export default workflow`. + +### 5.7 Hidden Commands — All Removed + +| Old | Status in 2.0 | Replacement | +| --- | --- | --- | +| `_orchestrator-entry` | **Deleted.** | Daemon imports the workflow file and runs `definition.run(ctx)` in its own event loop. | +| `_emit-workflow-meta` | **Deleted.** | Daemon imports each registered workflow at boot; `workflow/list` returns the cached metadata. | +| `_atomic-run` | **Deleted.** | `workflow/start` is the dispatch path. | +| `_cc-debounce` | **Deleted.** | No tmux hooks.

Alternatives Considered + +| Option | Pros | Cons | Reason for Rejection | +| --- | --- | --- | --- | +| **Selected** — daemon + tmux removal + zero hidden commands | Unified protocol surface; self-contained runtime; cross-platform parity; SDK auto-install for free; multi-attach for free; sets up future cloud / IDE integrations | Major version bump; substantial rewrite; PTY library is a new dep; OpenTUI must mature its terminal-emulator surface | **Selected.** The architectural payoff justifies the rewrite cost; the dependencies all exist; clean cutover is easier than a forever-deprecation. | +| Keep tmux, add `--ui-server` only (the v1 of the prior draft) | Minimal scope; ships in weeks; backward compatible | `_cc-debounce` and the other hidden commands stay; tmux dep stays; SDK self-exec parity gap with Claude Agent SDK persists; cross-platform fragility continues | Rejected. Lands a thin RPC veneer over a runtime that still has the structural problems we wanted to solve. | +| Daemon over Unix socket | UID-scoped via filesystem permissions; no port collision | Unsupported by the established design pattern; Windows Unix-socket support is uneven; no token discovery story for non-PATH'd clients | Rejected. TCP loopback is the established pattern. | +| Hand-rolled JSON-RPC over Bun WebSocket | Bun-native; one fewer dep | ~200 LOC of dispatcher to maintain; non-standard framing; clients need atomic-specific code | Rejected. `vscode-jsonrpc` is the cost-effective choice. | +| `node-pty` instead of `bun-pty` | Older, more battle-tested | Native bindings; prebuilt-multiarch package required for distribution; Bun compatibility quirks | Rejected as default. Keep as fallback if `bun-pty` proves unstable on a target platform. | +| Adopt `vscode-jsonrpc` as wire only, keep tmux for process supervision | Smallest dep delta | Doesn't unify the architecture; hidden commands stay | Rejected. Half-measure. | +| Refuse stdio support entirely | Smaller protocol surface | Loses parity with the established design; closes off embedded-SDK use cases | Rejected. Stdio is supported at the `UIServer` API level (the daemon binds to stdio when `--stdio` flag is given for non-singleton uses like CI containers). | + +--- + +## 7. Cross-Cutting Concerns + +### 7.1 Security and Privacy + +- **Loopback-only TCP bind.** Daemon binds `127.0.0.1`. No `--host` override in v1. +- **Token authentication.** `connect({ token })` matched against `ATOMIC_UI_SERVER_TOKEN` via `timingSafeEqual`. If env var unset, the daemon logs a warning and accepts any token (matches the established design's permissive default for loopback). +- **Token sourcing.** The SDK auto-spawn flow generates a 32-byte random token if `ATOMIC_UI_SERVER_TOKEN` isn't already set in the consumer's env, and exports it for both itself and the spawned daemon. Tokens are not logged. +- **Threat model:** + - Remote attackers → blocked by `127.0.0.1` bind. + - Other local users on a multi-user machine → blocked by token (if set). Operators who want strong isolation always set the env var. + - Same-UID processes → can read each other's `/proc//environ`; this is the same trust boundary as `0o600` files. + - Replay across runs → tokens are per-daemon-lifetime; daemon restart generates a fresh token. +- **Data sensitivity.** Workflow transcripts may contain user prompts and agent outputs with secrets. The data is already on disk under `~/.atomic/sessions///messages.json` (1.x) or in the daemon's per-stage scrollback (2.0); JSON-RPC exposure on a token-authenticated loopback connection doesn't increase the attack surface. +- **Permission scope.** Every authenticated client has full method access. v1 has no per-client / per-method ACL. + +### 7.2 Observability Strategy + +- **Logs**: daemon writes to `~/.atomic/daemon.log`. Connection open/close, method names (not params), and errors logged. +- **Telemetry**: server-emitted events at lifecycle boundaries: + - `daemon_started` — `{ pid, atomicVersion, protocolVersion }` + - `daemon_stopped` — `{ uptimeMs, totalRuns, totalConnections, totalMethodCalls }` + - `run_started` / `run_ended` — per workflow run +- **Client-driven telemetry**: `protocol/sendTelemetry({ event, payload })` lets clients append events with `clientName` + `ts` stamped on. Same JSONL sink. +- **Debug**: `ATOMIC_UI_SERVER_DEBUG=1` enables per-method param logging (with secrets redacted). + +### 7.3 Scalability and Capacity Planning + +- **Connection count**: not capped by application; OS fd limit applies. Consistent with established JSON-RPC server practice. +- **Concurrent runs**: daemon supports N runs; each run allocates one Bun event-loop coroutine + N PTYs. Memory dominated by per-stage scrollback (default 4 MiB × stages). 100 concurrent runs at typical workflow size: ~2 GiB. Reasonable for a developer machine; CI may want lower scrollback caps. +- **PTY data throughput**: `bun-pty` async reads; daemon broadcasts to subscribers. Bottleneck is the slowest client. v1 uses non-blocking writes; backpressure on a slow client → close that client (`bufferedAmount > 1 MiB` → `dispose()`). +- **`workflow/list`**: O(N) over the in-memory registry, served from cache. No subprocess fork. + +--- + +## 8. Migration, Rollout, and Testing + +### 8.1 Rollout + +**Hard cutover. No feature flags. No backward-compat shims. No coexistence with 1.x.** + +`atomic 2.0.0` is a major version bump that breaks every prior contract: tmux-based sessions, hidden subcommands, the self-exec dispatcher, `hostLocalWorkflows`, every primitive's underlying transport. Users upgrade by accepting the break — there is no transitional mode where 1.x behavior is preserved behind a flag. + +**Implementation sequencing on the development branch:** + +The work is staged for engineering tractability, not for user-facing rollout. Pre-release semver (`2.0.0-alpha.N`, `2.0.0-beta.N`, `2.0.0-rc.N`) tracks integration milestones during development; **only `2.0.0` is published to the `latest` dist-tag**. Pre-releases publish to `next` for development testing. + +| Sequence | Work landed | Pre-release tag | +| --- | --- | --- | +| 1 | `atomic --ui-server` daemon mode + read-side JSON-RPC methods (`workflow/list`, `workflow/refresh`, `run/*`, `panel/*`, `protocol/*`). SDK auto-spawn + connect. | `2.0.0-alpha.1` | +| 2 | `bun-pty` dep + `Supervisor` class. Provider migration off tmux: OpenCode → Copilot → Claude. Each provider migrated deletes its tmux-specific helper code. | `2.0.0-alpha.2..N` | +| 3 | `panel-client.tsx` + `pty-pane.tsx` OpenTUI widget. `OrchestratorPanel` detaches from the orchestrator pane process. `atomic workflow ...` mounts the panel client. `atomic workflow attach ` for reattach. | `2.0.0-beta.1` | +| 4 | Hidden subcommands deleted: `_orchestrator-entry`, `_emit-workflow-meta`, `_atomic-run`, `_cc-debounce`. `runtime/orchestrator-entry.ts`, `runtime/cc-debounce.ts`, `runtime/self-exec.ts` files removed. Boot context flows over RPC end-to-end. | `2.0.0-beta.2` | +| 5 | `runtime/tmux.ts`, `runtime/attached-footer.ts`, `tui/` deleted. `lib/spawn.ts:ensureTmuxInstalled` and `auto-sync.ts` tmux flow deleted. `hostLocalWorkflows` removed from SDK exports. CI matrix loses the tmux-version axis. | `2.0.0-rc.1` | +| 6 | Migration guide written. README, workflow-creator skill, every example rewritten. Final QA. Ship to `latest`. | **`2.0.0`** | + +**No `ATOMIC_DAEMON_MODE` env var, no `--use-tmux` escape hatch, no dual-runtime mode.** Each pre-release is internally consistent — at any point on the development branch, the runtime is exactly what that pre-release tag describes, not a runtime configurable into either mode. + +**Migration is a clean cutover for users:** +- Workflow source files calling `hostLocalWorkflows([wf])` at the top level break at import time. Migration guide instructs `export default workflow` instead. +- Running 1.x tmux sessions are not migrated. Users let them complete or `tmux kill-server -L atomic` before upgrading. +- 1.x on-disk artifacts under `~/.atomic/sessions//` are ignored by 2.0; operators can `rm -rf` them. +- 1.x `settings.json` workflow registrations work as-is — the schema is unchanged; only the dispatch path differs. + +### 8.2 Test Plan + +#### 8.2.1 Unit tests + +For each method handler, paired `MessageConnection`s over `Duplex` streams (no real socket): + +```ts +import { Duplex } from "node:stream"; +import { createMessageConnection, StreamMessageReader, StreamMessageWriter } from "vscode-jsonrpc/node"; + +function pair(): [MessageConnection, MessageConnection] { + const a = new Duplex({ read() {}, write(c, _e, cb) { b.push(c); cb(); } }); + const b = new Duplex({ read() {}, write(c, _e, cb) { a.push(c); cb(); } }); + return [ + createMessageConnection(new StreamMessageReader(a), new StreamMessageWriter(a)), + createMessageConnection(new StreamMessageReader(b), new StreamMessageWriter(b)), + ]; +} +``` + +For each method: positive path, every documented error case, schema validation failure → `-32602`. + +For `panel/subscribe`: subscribe → mutate fake `PanelStore` → assert notification arrives. Subscribe twice → idempotent. Disconnect with subscription active → no leak. + +For supervisor: spawn fake PTY against a `cat`-like process, verify scrollback growth, output broadcast to subscribers, exit propagation. + +For daemon-singleton enforcement: spawn first daemon, write endpoint file. Spawn second daemon → reads file → connects → exits with the existing endpoint info. + +#### 8.2.2 Integration tests + +Real `net.createServer` over loopback + real PTY against a fake `cat`-like agent process. Exercise: + +- TCP connect + `connect` with valid token → success. +- TCP connect + `connect` with invalid token → `AUTHENTICATION_REQUIRED` + connection close. +- Empty `ATOMIC_UI_SERVER_TOKEN` → server warns; any token accepted. +- `workflow/list` → returns expected count from a fake registry. +- `workflow/start` → spawns a fake stage; `panel/update` notifications arrive; `pane/output` notifications arrive when the fake agent prints. +- Detach (close client) → daemon retains state. Reconnect → `panel/get` returns fresh state. +- Multi-attach: two clients subscribed; both receive every notification. +- `run/stop` → SIGTERM to PTYs; subprocess dies; `pane/exit` notification fires. +- Daemon SIGTERM → `server/closing` to all clients; clean exit. + +#### 8.2.3 Cross-platform CI + +Test matrix: Linux x64, macOS arm64, Windows x64. PTY behavior is the highest-risk axis — Windows ConPTY support must be exercised end-to-end on every commit. + +#### 8.2.4 Migration test + +Build a fake atomic 1.x sessions directory; start atomic 2.0; verify the daemon ignores it cleanly and starts a fresh registry.

Open Questions / Unresolved Issues + +All architecturally-load-bearing decisions have been made: + +- [x] **Process model.** Daemon + JSON-RPC + no tmux. Confirmed. +- [x] **Daemon scope.** Per-user singleton over TCP loopback. Mirrors the established pattern. +- [x] **Wire layer.** `vscode-jsonrpc` over LSP `Content-Length` framing. Confirmed. +- [x] **Auth.** TCP via `ATOMIC_UI_SERVER_TOKEN` env var + `connect({ token, clientName })`; permissive default with warning if unset. +- [x] **PTY library.** `bun-pty` primary; `node-pty` fallback if a target platform proves unstable. +- [x] **Hidden commands.** All removed. +- [x] **Boot context.** Over RPC, not env vars. +- [x] **Detach/reattach.** Connection-layer, not tmux-layer. +- [x] **Multi-attach.** First-class; daemon broadcasts to N subscribers. + +The following are implementation-detail decisions resolved during Phase 1: + +- [ ] **Default scrollback cap.** Spec proposes 4 MiB per stage. Confirm during Phase 1; lower for memory-constrained CI. +- [ ] **Daemon idle timeout.** Should the daemon auto-shutdown after N minutes with no clients and no active runs? Pro: clean lifecycle on dev machines. Con: re-spawn cost. Default proposal: no auto-shutdown — daemon runs until SIGTERM or user logout. +- [ ] **Workflow file hot-reload.** When a registered workflow file changes on disk, `workflow/refresh` re-imports. Should the daemon also auto-watch and refresh? Default proposal: no — explicit refresh only, to avoid surprise re-imports while a run is mid-flight. +- [ ] **PTY library Windows behavior.** Verify ConPTY support is solid for our agent CLIs. If not, fall back to `node-pty` on Windows only. + +These are not blocking; the Phase 1 implementer resolves them with measurements. From c4d4dda03f857b224237a441dfcc9f856c27bc7a Mon Sep 17 00:00:00 2001 From: Norin Lavaee Date: Sat, 9 May 2026 22:03:04 +0000 Subject: [PATCH 02/50] fix(file-discovery): scrub git env vars so cwd controls the repo When listAllFiles runs inside a git hook (pre-commit, pre-push), the parent git invocation exports GIT_DIR/GIT_WORK_TREE/GIT_INDEX_FILE so its child processes operate on the same repo. Those override the spawned `git ls-files`'s cwd, causing it to list the parent repo's files instead of the target root. Strip the git-discovery env vars (plus GIT_OBJECT_DIRECTORY, GIT_ALTERNATE_OBJECT_DIRECTORIES, GIT_NAMESPACE, GIT_CEILING_DIRECTORIES, GIT_DISCOVERY_ACROSS_FILESYSTEM) before invoking git or rg so cwd is the source of truth. Manifested as 6 deterministic test failures under the prek pre-push hook (file-discovery.test.ts, preflight.real-spawn.test.ts) that passed when run directly because no parent git process was setting those env vars.

The disk writer (`~/.atomic/sessions//status.json`) is a persistence shadow, not canonical state. +- **All workflow control flows through JSON-RPC 2.0.** Discovery, dispatch, lifecycle, panel state, and PTY I/O are all methods and notifications on the daemon's JSON-RPC protocol surface (`vscode-jsonrpc` over LSP `Content-Length` framing). +- **Hidden subcommands removed.** `_orchestrator-entry`, `_emit-workflow-meta`, `_atomic-run`, and `_cc-debounce` are gone. Their dispatch roles are replaced by RPC methods on the daemon. +- **`hostLocalWorkflows([wf])` removed from SDK exports.** Replace with `export default workflow` in workflow source files. +- **SDK auto-installs the platform binary via `optionalDependencies`.** `@bastani/atomic-sdk` declares every `@bastani/atomic-${platform}-${arch}` variant as an optional dep. SDK-only users no longer hit `MissingDependencyError` for a missing binary. + +--- + +## Breaking changes + +### Workflow source files calling `hostLocalWorkflows([wf])` at the top level break at import time + +`hostLocalWorkflows` is deleted from the SDK surface. Any workflow file that calls it at the module top level will throw at import time under 2.0. + +**Before (1.x):** + +```ts +import { hostLocalWorkflows } from "@bastani/atomic-sdk"; +import { myWorkflow } from "./my-workflow.js"; + +hostLocalWorkflows([myWorkflow]); +``` + +**After (2.0):** + +```ts +import { myWorkflow } from "./my-workflow.js"; + +export default myWorkflow; +``` + +The daemon imports registered workflow files directly and reads the default export. + +--- + +### Running 1.x tmux sessions are not migrated + +atomic 2.0 cannot reattach to a tmux session created by atomic 1.x. Let in-flight 1.x runs complete before upgrading, or terminate them: + +```sh +tmux kill-server -L atomic +``` + +--- + +### 1.x on-disk artifacts under `~/.atomic/sessions//` are ignored by 2.0 + +The 2.0 daemon initializes an empty run registry. Existing session artifacts on disk are not read. Operators can remove them safely: + +```sh +rm -rf ~/.atomic/sessions/ +``` + +--- + +### Detach/reattach is now connection-layer, not tmux-layer + +In 1.x, detach/reattach was a tmux concept. In 2.0, detach means the panel client closes its connection; the daemon retains the run state. Reattach means a new client connects and subscribes. + +Use the new public command: + +```sh +atomic workflow attach +``` + +There is no tmux-layer concept involved. + +--- + +### `attachSession` primitive is no longer blocking + +In 1.x, `attachSession` called `Bun.spawnSync` with inherited stdio — blocking the event loop. In 2.0, `attachSession` is replaced by `run/getAttachInfo`, which returns a `subscriptionId`. The caller drives the panel client. + +**Before (1.x):** + +```ts +// Blocking — froze the event loop +await attachSession(runId); +``` + +**After (2.0):** + +```ts +const conn = await connectToDaemon(); +const { subscriptionId } = await conn.sendRequest("run/getAttachInfo", { runId }); +// subscriptionId is used to drive the panel client; the call returns immediately +``` + +--- + +## What stayed the same + +- **`~/.atomic/settings.json` schema is unchanged.** Workflow registrations in settings work as-is. Only the dispatch path changed (RPC instead of self-exec). +- **`WorkflowDefinition` API surface is unchanged.** All fields, methods, and types on `WorkflowDefinition` work as before. The only difference is how the daemon dispatches a workflow — through `workflow/start` RPC, not hidden subcommands. + +--- + +## Step-by-step upgrade + +1. Let any in-flight 1.x runs complete, OR terminate them: + + ```sh + tmux kill-server -L atomic + ``` + +2. (Optional) Remove 1.x session artifacts: + + ```sh + rm -rf ~/.atomic/sessions/ + ``` + +3. Install the 2.0 SDK. The binary is auto-installed via `optionalDependencies`: + + ```sh + bun add @bastani/atomic-sdk@2 + ``` + +4. Update workflow source files: remove any `hostLocalWorkflows([workflow])` call and export the workflow definition as the default export instead: + + ```ts + // Remove this: + // hostLocalWorkflows([myWorkflow]); + + // Add this: + export default myWorkflow; + ``` + +5. Update any code calling `attachSession` — it is now non-blocking. See the [Breaking changes](#attachsession-primitive-is-no-longer-blocking) section above for the replacement pattern. + +6. Run `atomic workflow ...` as before. The SDK auto-spawns the daemon on first use. + +--- + +## FAQ + +**Can I run 1.x and 2.0 side by side?** + +No. Pin one version per workspace. 1.x and 2.0 cannot coexist on the same machine without isolation (e.g., separate containers or separate user accounts). The daemon discovery file (`~/.atomic/daemon.endpoint.json`) and the session artifact layout differ between major versions. + +**What happened to tmux?** + +Replaced by the daemon's process supervisor, which allocates PTYs using `bun-pty`. Agent CLIs (Claude Code, Copilot CLI, OpenCode) are now PTY-attached subprocess clients of the daemon. The psmux Windows fork and every tmux-specific helper are deleted. + +**How do I attach to a backgrounded run?** + +```sh +atomic workflow attach +``` + +The daemon retains full run state while no panel is attached. Any number of clients can attach simultaneously; each renders independently. diff --git a/packages/atomic-sdk/docs/ui-server.md b/packages/atomic-sdk/docs/ui-server.md new file mode 100644 index 000000000..5c7c6b212 --- /dev/null +++ b/packages/atomic-sdk/docs/ui-server.md @@ -0,0 +1,805 @@ +# Atomic UI Server (JSON-RPC daemon) + +`atomic --ui-server` is the per-user singleton daemon that backs every workflow in atomic 2.0.

Client opens `net.connect({ host: "127.0.0.1", port })`. +2. Server's `net.createServer` accepts; attaches `MessageConnection` via `createMessageConnection(new StreamMessageReader(socket), new StreamMessageWriter(socket))`; calls `conn.listen()`. +3. Connection starts unauthenticated. Only `protocol/getVersion` and `connect` succeed. +4. Client calls `connect({ token, clientName })`. Token is compared against `process.env.ATOMIC_UI_SERVER_TOKEN` with `timingSafeEqual`. If env var unset, the daemon logged a warning at start and accepts any value. `clientName` is mandatory. +5. After `connect`, client calls any method. +6. Daemon shutdown: emits `server/closing` to every connection, waits 100ms for buffered writes, calls `MessageConnection.dispose()` per connection, then `net.Server.close()`. + +### Detach and reattach + +**Detach** = client closes connection. Daemon's `panel/subscribe` cleanup removes the subscriber from the broadcast set. The run continues. + +**Reattach** = new client connects, subscribes, calls `panel/get` for current snapshot, calls `pane/getScrollback` for any stages needing history. Multiple simultaneous reattaches work: all subscribe, all receive notifications. + +**Background runs:** `atomic workflow ... -d` calls `workflow/start` and returns without mounting a panel client. Run continues; user calls `atomic workflow attach ` later. + +--- + +## Process Supervisor + +The supervisor owns every agent subprocess via `bun-pty`. No tmux. + +### Per-stage state + +```ts +interface SupervisedStage { + runId: string; + stageName: string; + agent: AgentType; + pty: import("bun-pty").IPty; // PTY handle: write(), kill(), onData, onExit + scrollback: RingBuffer; // bounded byte buffer (default 4 MiB) + scrollbackHead: number; // monotonically increasing offset + outputSubscribers: Set; // clients receiving pane/output + startedAt: number; + endedAt: number | null; + exitCode: number | null; +} +``` + +### PTY model + +Each agent stage gets one PTY allocated via `bun-pty.spawn(...)`. The daemon reads from the PTY into a per-stage `RingBuffer` (default 4 MiB) and broadcasts each chunk to subscribed clients as `pane/output`. Input forwarding (`pane/sendInput`) calls `pty.write(data)` directly — no daemon-side buffering. + +Default PTY dimensions: `cols: 120, rows: 40`. Resize is post-v2.0. + +### Scrollback semantics + +`scrollbackHead` is a monotonically increasing byte offset. Clients track their last-seen offset and pass it as `fromOffset` to `pane/getScrollback` on reconnect. `pane/output` notifications include `offset` (the head after writing) so clients can stay synchronized. Ring buffer evicts oldest bytes when full; clients that fall behind receive a gap in offset continuity. + +### Death detection + +`pty.onExit` is the sole source of truth. No timer-based liveness polling. On exit: +1. Daemon records `endedAt` and `exitCode`. +2. Broadcasts `pane/exit { runId, stageName, exitCode, signal }` to all subscribers. +3. Calls `panelStore.sessionEnded(stageName, status, errorMessage?)` where `status` is `"complete"` when `exitCode === 0`, `"error"` otherwise, and the optional `errorMessage` is only set when `status === "error"` (e.g. `exited with code ${exitCode}`). +4. If last stage, emits `run/ended`. + +--- + +## Observability + +### Logs + +Daemon logs to `~/.atomic/daemon.log`. Events logged: + +- Connection open / close (with `clientName`) +- Method names (not params, unless debug mode enabled) +- All errors with stack traces +- Daemon start / stop + +### Telemetry events + +Server emits structured telemetry events at lifecycle boundaries: + +| Event | Fields | +| --- | --- | +| `daemon_started` | `{ pid, atomicVersion, protocolVersion }` | +| `daemon_stopped` | `{ uptimeMs, totalRuns, totalConnections, totalMethodCalls }` | +| `run_started` | `{ runId, workflowName, agent }` | +| `run_ended` | `{ runId, overall, durationMs }` | + +Client-driven telemetry: `protocol/sendTelemetry({ event, payload })` lets clients append events. Daemon stamps `clientName` and `ts` before writing to the JSONL sink. + +### Debug mode + +`ATOMIC_UI_SERVER_DEBUG=1` enables per-method param logging with secrets redacted.

Reads `~/.atomic/daemon.endpoint.json` to get `port`. +2. Opens `net.connect({ host: "127.0.0.1", port })`. +3. Creates a `MessageConnection`. +4. Sends `connect({ token: process.env.ATOMIC_UI_SERVER_TOKEN, clientName: "example-client" })`. +5. Sends `panel/subscribe({})`. +6. Logs 5 `panel/update` notifications. +7. Sends `panel/unsubscribe`. +8. Disposes connection and exits. + +See `examples/ui-server-client/README.md` for usage.
