chore: snapshot working tree - pty_exited notifications + in-flight inference WIP

feat(booterm): structured pty_exited WS notifications. Plan-validated, impl-validated, code-reviewed green (contracts build clean, contracts test 29/29, booterm + web typecheck clean).

wip: in-progress inference/provider refactor (agents.ts, provider.ts, new llama-providers.ts, removed llama-args-validator), plus arena, dispatcher, compaction, schema changes.

openspec: pty-exit-notifications complete; x-agent-flags planned (not yet implemented).

+# Paseo-like Orchestrator — Implementation Plan
+
+> **Goal:** Transform BooCode into a Paseo-style thin-client orchestration layer with observability, dynamic workflows, resumability, background subagents, multi-modal, and cache shape telemetry.
+>
+> **Architecture:** Durable agent execution engine beneath thin chat/coder frontends. Trace system as foundation, workflow engine as the structural addition, everything else layered on top.
+>
+> **Inspired by:** Paseo (agent lifecycle, worktree isolation), Whale (workflow engine, cache telemetry), OpenCode (session resume), Claude Code (workflow script format).
+
+---
+
+## TL;DR
+
+> **Quick Summary**: Build a durable orchestration layer with trace observability, dynamic JS workflows, session persistence, background subagents, and multi-modal support over 5 phases.
+>
+> **Deliverables**:
+> - Trace system with DB persistence + viewer UI
+> - Dynamic workflow engine (JS sandbox, agent/parallel/pipeline)
+> - Workflow resumability (hash-based step caching)
+> - Background subagent runtime
+> - Session persistence across refreshes
+> - Cache shape telemetry (DeepSeek KV cache viz)
+> - Multi-modal attachment support
+>
+> **Estimated Effort**: XL — 5 phases, ~2-3 weeks total
+> **Parallel Execution**: YES — phases 1-2 can partially overlap
+> **Critical Path**: Trace system → Workflow engine → All downstream features
+
+---
+
+## Context
+
+### Original Request
+User wants BooCode to become "like Paseo — a thin client" with observability, dynamic workflows, session persistence, background agents, multi-modal, cache shape telemetry, and workflow resumability. They invoked skills across model evaluation, long context, SGLang, LangChain, LangSmith, agentic eval, agent harness construction, agent governance, and chat SDKs — indicating broad ambition for a production-quality AI coding platform.
+
+### Key Decisions
+- **Trace system first**: Foundation for all debugging and optimization
+- **isolated-vm for workflow sandbox**: Node-native, no external deps
+- **DB-backed sessions**: Postgres for trace store + session state
+- **Existing WS frames + new `tool_trace` frame**: Live streaming to frontend
+- **Phase ordering**: Foundation (trace) → UX (persistence) → Power (workflows) → Polish (background/multi-modal/cache)
+
+---
+
+## Phases
+
+### Phase 1: Trace System + Observability
+**Est. effort**: 3-4 days
+
+Core observability infrastructure. Every tool call gets timed, logged, and persisted.
+
+**Deliverables**:
+- `tool_traces` DB table (id, session_id, chat_id, turn_number, tool_name, input, output, started_at, finished_at, latency_ms, tokens_used, cache_tokens, reasoning_tokens, error, outcome)
+- Instrumentation in `tool-phase.ts` wrapping `executeToolCall` with start/end timing
+- `tool_trace` WS frame type for live streaming to frontend
+- GET `/api/chats/:id/traces` endpoint (paginated)
+- Trace viewer pane (collapsible tree, timing bars, expand/collapse per call)
+
+**Files to create**: 5-7 files across server + web + contracts
+**Dependencies**: None — standalone feature
+
+---
+
+### Phase 2: Session Persistence + Resume
+**Est. effort**: 2-3 days
+
+Agent state survives browser refresh. Active sessions can be resumed.
+
+**Deliverables**:
+- Serialize active agent state to DB on each turn boundary
+- Restore state on WS reconnect (existing `snapshot` frame enhanced)
+- Agent session timeline view (history of all turns in a session)
+- Coder pane rehydrates from persisted state
+
+**Files to modify**: ws.ts, useSessionStream.ts, session store, dispatcher
+**Dependencies**: None — standalone, but benefits from Phase 1 trace data
+
+---
+
+### Phase 3: Dynamic Workflow Engine
+**Est. effort**: 5-7 days
+
+JS sandbox for multi-agent orchestration. Claude Code compatible.
+
+**Deliverables**:
+- `isolated-vm` sandbox (or Node `vm` module with restricted context)
+- Workflow API: `agent()`, `parallel()`, `pipeline()`, `phase()`, `budget()`, `log()`, `args`
+- Workflow file discovery (`.boocode/workflows/*.js` → project, `~/.boocode/workflows/*.js` → global)
+- Built-in workflow catalog (deep-research, multi-review, etc.)
+- Workflow manager with concurrency limits, token budgets
+- Integration with existing Orchestrator panel for UI
+
+**Files to create**: 10-15 files (workflow runtime, scheduler, tool bridge, manager, catalog)
+**Dependencies**: Phase 1 traces feed into workflow observability
+
+**Workflow Resumability** (within Phase 3):
+- SHA-256 hash of agent spec (prompt + options)
+- Cache completed results by hash
+- On re-run, skip cached agents, only execute new/changed ones
+- In-memory cache for current session, optional DB persistence
+
+**Est. effort**: 1-2 days within Phase 3
+
+---
+
+### Phase 4: Background Subagents
+**Est. effort**: 2-3 days
+
+Non-blocking subagent execution. `spawn_subagent` returns immediately, results collected later.
+
+**Deliverables**:
+- Background task queue (reuses existing `tasks` table)
+- `spawn_subagent` tool that creates a task and returns immediately
+- `subagent_status` tool to poll completion
+- `subagent_result` tool to retrieve output
+- Background agent pane showing running/completed subagents
+- Notifications via hooks when background tasks complete
+
+**Files to create**: 3-5 files across server + web
+**Dependencies**: Phase 1 traces, Phase 2 session persistence
+
+---
+
+### Phase 5: Multi-modal + Cache Shape (Polish)
+**Est. effort**: 2-3 days
+
+Image/file attachment support + DeepSeek cache hit visualization.
+
+**Deliverables (Multi-modal)**:
+- Image/file attachment storage (tmpfs, referenced in message)
+- Forward image content through DeepSeek API's multimodal support
+- Render attached images in message bubble
+- Model can "see" screenshots, diagrams, UI mocks
+
+**Deliverables (Cache Shape)**:
+- Extract `prompt_cache_hit_tokens` from DeepSeek provider metadata
+- Build cache segment visualization (system prompt, tool schema, conversation)
+- Per-turn cache hit rate in trace viewer
+- Cumulative cache stats in session view
+
+**Files to create**: 3-5 files
+**Dependencies**: Phase 1 traces (for cache shape), existing DeepSeek integration
+

+## v2.8.25-codecontext-removal — 2026-06-08
+
+Removes all remaining Go codecontext sidecar references. The 17 native codecontext tool wrappers (`get_codebase_overview`, `search_symbols`, `get_blast_radius` etc.) have been deleted from the source tree. Code analysis tools are now provided entirely by the boocontext MCP server, discovered at startup via `appendMcpTools()`. All 9 previously unavailable boocontext MCP tools (`get_summary`, `scan`, `get_coverage`, `get_schema`, `get_env`, `get_events`, `get_knowledge`, `get_wiki_index`, `lint_wiki`) are now wired into every relevant agent's tool list in `data/AGENTS.md`. Stale entries removed from `STANDARD_TOOL_NAMES`, `BUILT_IN_TOOLS`, `SYNTHESIS_TOOLS`, and `ToolCallLine.tsx`. Guidance files (`CLAUDE.md`, `BOOCHAT.md`) updated. 22 files deleted (~2,400 lines removed). Pairs with v2.8.20-sidecar-teardown which removed the Docker service.
+
+## v2.8.24-memory-supervisor-streaming — 2026-06-08
+
+Ships the inference state-graph and supervisor architecture — a non-blocking step machine with `StateGraph` nodes and edge transitions, replacing the single-path inference loop. Adds a Supervisor agent (tools: '*' wildcard) for dynamic request routing. Integrates the TypeScript boocontext MCP server for tree-sitter code analysis (health, impact, types). Adds memory management tools (`extract_memory`, `manage_memory`, `search_memory`) for cross-session context persistence. Extends `ws-frames.ts` with `agent_message` channel for inter-agent messaging. PTY sessions gain rich metadata (`description`, `parentAgent`) threaded through the full stack. Web: message-parts components (ActionRow, CompactCard, SummaryCard, ReasoningBlock, StatsLine), ComparePane, Memory page, MCP permission dialog, keyboard shortcuts, ErrorBoundary. Booterm: `sweepExpired()` for idle/absolute timeouts. Conductor: `collision-detector` + `conflict-index` tests. Guidance audit: resolution order, failure modes, refusal discipline across all guidance files.
+
+## v2.8.23-wave2-complete — 2026-06-08
+
+Parallel batch execution and SWITCH branching step for the conductor. `buildBatchState` and `getReadyInBatch` gate agent dispatch concurrency. `SwitchCase` with `resolveSwitch` lets flow steps route via conditionals. Prepares the scheduler for DO_WHILE and FORK_JOIN steps.
+
+## v2.8.22-wave1-complete — 2026-06-08
+
+Paseo hub integration: `paseo-client.ts` (thin HTTP+CLI client) and `backends/paseo.ts` (AgentBackend implementation) for dispatching to Paseo agents. Collision detection: `collision-detector.ts` with `ConflictVerdict` scoring, `conflict-index.ts` with register/sweep lifecycle, `collision_warning` WS frame. PTY search: `search.ts` route with regex-based ring buffer search across PTY session output. Backported from the earlier Wave 1 branch.
+
+## v2.8.21-state-machine — 2026-06-08
+
+Extended the flow-runner task state machine with `TIMED_OUT` status and retriable step support. Steps with `max_retries` auto-retry on failure; `retry_count` tracks attempts. `timedOut` set in SchedulerState gates downstream dependents from running while the timed-out step is retried.
+
+## v2.8.20-paseo-orchestrator-ph3-5 — 2026-06-08
+
+Completes the Paseo-like Orchestrator with phases 3–5. Phase 3 ships a Dynamic Workflow Engine built on Node's `vm` sandbox — Claude Code compatible JavaScript workflows with `agent()`, `parallel()`, `pipeline()`, `phase()`, and `budget()` primitives. Includes a built-in workflow catalog (`deep-research`, `review-code`, `find-issues`) with SHA-256 hash-based resumability cache that skips completed steps on re-run. Phase 4 adds background subagents — `spawn_subagent` returns immediately, `subagent_status` and `subagent_result` tools let the model poll and collect results. Phase 5 adds a cache shape telemetry badge to the trace viewer (colored bar + hit rate percentage) and a multi-modal attachment stub. Also ships inline diff snippets in the chat stream after write tool calls, and the `run_command` tool with auto-fix loop that detects build failures after edits and injects errors for self-correction.
+
+## v2.8.19-paseo-orchestrator-ph1-2 — 2026-06-08
+
+Ships the trace system and session persistence backbone. Every tool call is now timed via `tool_traces` DB table with latency, token counts, cache/reasoning breakdowns, and WS frames streamed live to a new trace viewer pane. Agent sessions survive browser refresh — `agent_snapshots` table persists state on turn boundaries and restores on WebSocket reconnect. A session timeline view shows agent turn history with scroll-to and restore. New frontend components: `TraceViewer` (collapsible panel with timing bars) and `SessionTimeline` (vertical timeline).

+## v2.8.18-deepseek-whale-lift — 2026-06-08
+
+Integrates DeepSeek API directly into BooChat and BooCoder via `@ai-sdk/deepseek`, replacing the generic `openai-compatible` wrapper. DeepSeek V4 models (`deepseek-v4-flash`, `deepseek-v4-pro`) with configurable thinking effort levels appear in both chat and coder pane model pickers. Full token tracking — cache hit tokens and reasoning tokens — flow from the API through new DB columns and WS frames into the UI message stats line. Lifts three high-value features from the Whale codebase: a schema-based tool input repair system that coerces types and unwraps markdown autolinks before Zod validation, a shell-based lifecycle hooks system (PreToolUse, PostToolUse, Stop, PreCompact, PostCompact) with JSON stdin/stdout contract, and per-MCP-server permissions (allow/ask/deny) gating tool execution.
+
 ## v2.8.0-fork-lifts — 2026-06-07
 
 Completes the eight fork-lift integrations from `/opt/forks` into BooCode: boocontext sidecar upgrade, LSP code intelligence, DCP clean-room pruning, institutional memory, subagent protocol enhancements, plugin hook host, inference reliability (tool-shim + loop detectors), and TokenScope token breakdown. Backfills edit safety guards (truncation + dropped imports) and the TokenScope analyzer/persist module. Closes the fork-lifts-mit epic.

-- `os/exec` child supervisors must call `child.Wait()` in a goroutine and `os.Exit` on child death. `Signal(0)` returns nil on zombies and is NOT a liveness check.
