fix: update lockfile signatures and Nix hash

- Remove orphaned PID lock code from bootstrap (moved to supervisor)
- Fix worktree archive adapter to look up workspace by directory
- Replace registerWorktreeWorkspaceRecord with inline SQLite implementation
- Remove unused imports (stat, createPersistedWorkspaceRecord, PersistedProjectRecord)

+# Storage Revamp Plan
+
+Status: active rollout, phases 1 and 2 complete
+
+This document now tracks the storage revamp as it exists today, not as a speculative design exercise.
+The DB foundation and the project/workspace identity cutover have landed. What remains is the explicit
+creation/archive surface cleanup, timeline durability cutover, and final removal of legacy paths.
+
+## Goals
+
+- make structured records durable in Drizzle + SQLite
+- make projects and workspaces explicit first-class records
+- stop deriving project/workspace identity from agent `cwd`
+- keep agent snapshot persistence behind clear ownership
+- move committed timeline history to storage-owned rows
+- remove legacy JSON and in-memory authority once the DB path is proven
+
+## Out of scope
+
+- moving config, keypairs, push tokens, or server identity into the DB
+- persisting raw provider deltas or transport-only chunk streams
+- designing a hosted/remote database story beyond keeping the schema portable
+- durable reasoning history unless product explicitly asks for it later
+
+## Current state
+
+The storage revamp is no longer hypothetical.
+
+Completed:
+
+- Drizzle + SQLite database bootstrap is in place
+- `projects`, `workspaces`, and `agent_snapshots` use integer primary keys
+- `workspaces.project_id` and `agent_snapshots.workspace_id` cascade on delete
+- `agent_snapshots.workspace_id` is `NOT NULL`
+- legacy JSON import feeds the DB-backed structured records
+- project/workspace records use explicit `directory` fields instead of path-as-identity
+- session read paths now use persisted workspace/project rows instead of cwd/git derivation
+- `workspace-reconciliation-service.ts` is deleted
+- `workspace-registry-bootstrap.ts` is deleted
+- `workspace-registry-model.ts` is reduced to `normalizeWorkspaceId`
+
+Still pending:
+
+- explicit `create_project` / `create_workspace` API cleanup
+- final archive cascade behavior for descendants and live agents
+- committed timeline storage cutover
+- removal of remaining legacy JSON and in-memory committed-history authority
+
+## Converged decisions
+
+### Structured record authority
+
+Projects, workspaces, and agent snapshots are DB-backed structured records.
+The server should not recreate project/workspace identity from:
+
+- git remotes
+- worktree main-repo roots
+- normalized cwd strings
+
+Temporary exception:
+
+- agent creation may still find-or-create a workspace by directory if the UI has not yet provided
+  `workspaceId` explicitly
+
+That fallback is transitional and should be deleted once the client always sends the workspace id.
+
+### Storage seams
+
+The useful seams remain concrete and domain-shaped:
+
+- `ProjectRegistry`
+- `WorkspaceRegistry`
+- `AgentSnapshotStore`
+- `AgentTimelineStore`
+
+There is no reason to reintroduce a reconciliation service layer for project/workspace identity.
+
+### Timeline contract
+
+The long-term timeline contract remains:
+
+- committed rows are durable, canonical history
+- provisional live updates are transient subscription state
+- committed history is fetched by seq
+- provider history replay is not the durability mechanism
+
+The structured-record cutover is complete before the timeline cutover so timeline rows can rely on
+stable DB-backed agent and workspace identity.
+
+## Remaining phases
+
+### Phase 3: Explicit creation and archive cleanup
+
+Goal:
+Remove the last transitional write paths that still infer state from directories.
+
+Required work:
+
+- add explicit `create_project` handling
+- add explicit `create_workspace` handling
+- make agent creation require `workspaceId` once the UI is ready
+- finish archive semantics for workspaces/projects and any descendant agent state
+- remove the temporary find-or-create-by-directory fallback from agent creation
+
+Exit gate:
+
+- project/workspace creation is explicit end to end
+- no normal creation path infers identity from cwd or git metadata
+- archive flows behave consistently for structured records and live runtime state
+
+### Phase 4: Timeline storage cutover
+
+Goal:
+Make committed history durable and storage-owned.
+
+Required work:
+
+- make `AgentTimelineStore` authoritative for committed history
+- write one committed row per finalized logical item
+- support tail, before-seq, and after-seq queries from storage
+- stop treating provider history hydration as the normal refresh/load path
+- keep provisional live updates in memory only
+
+Exit gate:
+
+- committed history survives daemon restart
+- reconnect uses committed catch-up plus future live events without gaps or duplicates
+- unloaded agents can serve committed history from storage alone
+
+### Phase 5: Legacy cleanup
+
+Goal:
+Remove compatibility paths after the DB-backed model is fully authoritative.
+
+Required work:
+
+- remove legacy JSON authority for structured records
+- remove in-memory committed-history ownership
+- remove provider-history rehydrate compatibility paths
+- trim dead protocol and reducer logic from the pre-storage model
+- update architecture docs to match the final model
+
+Exit gate:
+
+- there is one durable storage path for structured records
+- there is one durable storage path for committed timeline history
+- the runtime no longer depends on the removed JSON/in-memory model
+
+## Data model summary
+
+### Projects
+
+- integer primary key
+- `directory` is unique
+- `display_name`
+- `kind`: `git | directory`
+- optional `git_remote`
+- timestamps and archive state
+
+### Workspaces
+
+- integer primary key
+- belongs to a project by `project_id`
+- `directory` is unique
+- `display_name`
+- `kind`: `checkout | worktree`
+- timestamps and archive state
+
+### Agent snapshots
+
+- `agent_id` remains the primary key
+- belongs to a workspace by integer `workspace_id`
+- `workspace_id` is required
+- timestamps, lifecycle state, persistence metadata, attention metadata, archive state
+
+### Timeline rows
+
+Target shape once Phase 4 lands:
+
+- `agent_id`
+- committed `seq`
+- committed timestamp
+- canonical finalized item payload
+
+Not part of durable history:
+
+- raw streaming chunks
+- provisional assistant text
+- provisional reasoning text
+
+## Verification requirements
+
+Every remaining phase should keep the same bar:
+
+- `npm run typecheck`
+- targeted tests for the touched storage/session/runtime paths
+- migration/import coverage when storage authority changes
+- reconnect and catch-up scenario coverage when timeline behavior changes
+
+At minimum, timeline cutover must explicitly prove:
+
+- `fetch-after-seq`
+- `fetch-before-seq`
+- restart durability
+- no-gap/no-duplicate reconnect behavior
+
+## Main risks
+
+- timeline work reintroduces provider-history replay as hidden authority
+- archive behavior diverges between stored records and live in-memory agents
+- explicit creation work leaves the transitional cwd fallback in place too long
+- cleanup stalls after compatibility paths stop being exercised
+
+## Rule of thumb
+
+If a new change needs to ask "what can we infer from this cwd?" for project or workspace identity,
+it is probably moving in the wrong direction.

+# Terminal Mode — Implementation Plan
+
+## Concept
+
+Terminal mode wraps an agent TUI (Claude Code, Codex, OpenCode, Gemini, etc.) in a Paseo agent entity. The agent is tracked in sessions, has a provider/icon/title, and can be archived — but instead of rendering a structured chat view, it renders a terminal running the agent's CLI.
+
+**Key principle:** `agent.terminal` is a boolean flag on the agent entity. If `true`, the panel renders a terminal. If `false` (default), it renders the current structured AgentStreamView.
+
+## What Changes
+
+### Phase 1: Server — Data Model & Provider Interface
+
+#### 1.1 Add `terminal` flag to `ManagedAgentBase`
+
+**File:** `packages/server/src/server/agent/agent-manager.ts`
+
+```typescript
+type ManagedAgentBase = {
+  // ...existing fields...
+  terminal: boolean;  // NEW — if true, this agent renders as a terminal TUI
+};
+```
+
+This flag is set at creation time and never changes. A terminal agent is always a terminal agent.
+
+#### 1.2 Add `terminal` to `AgentSessionConfig`
+
+**File:** `packages/server/src/server/agent/agent-sdk-types.ts`
+
+```typescript
+export type AgentSessionConfig = {
+  // ...existing fields...
+  terminal?: boolean;  // NEW — create as terminal agent
+};
+```
+
+#### 1.3 Add `terminal` to the Zod schema
+
+**File:** `packages/server/src/shared/messages.ts`
+
+Add to `AgentSessionConfigSchema`:
+```typescript
+terminal: z.boolean().optional(),
+```
+
+Add to the `AgentStateSchema` (the wire format sent to clients):
+```typescript
+terminal: z.boolean().optional(),
+```
+
+#### 1.4 Add terminal command builders to `AgentClient`
+
+**File:** `packages/server/src/server/agent/agent-sdk-types.ts`
+
+```typescript
+export type TerminalCommand = {
+  command: string;
+  args: string[];
+  env?: Record<string, string>;
+};
+
+export interface AgentClient {
+  // ...existing methods...
+
+  /**
+   * Build the shell command to launch this agent's TUI for a new session.
+   * Only available if capabilities.supportsTerminalMode is true.
+   */
+  buildTerminalCreateCommand?(config: AgentSessionConfig): TerminalCommand;
+
+  /**
+   * Build the shell command to resume an existing session in the agent's TUI.
+   * Only available if capabilities.supportsTerminalMode is true.
+   */
+  buildTerminalResumeCommand?(handle: AgentPersistenceHandle): TerminalCommand;
+}
+```
+
+#### 1.5 Add `supportsTerminalMode` capability
+
+**File:** `packages/server/src/server/agent/agent-sdk-types.ts`
+
+```typescript
+export type AgentCapabilityFlags = {
+  // ...existing flags...
+  supportsTerminalMode: boolean;  // NEW
+};
+```
+
+Also add to the Zod schema in `messages.ts`:
+```typescript
+supportsTerminalMode: z.boolean(),
+```
+
+#### 1.6 Implement terminal command builders in providers
+
+**Claude** (`packages/server/src/server/agent/providers/claude-agent.ts`):
+```typescript
+buildTerminalCreateCommand(config: AgentSessionConfig): TerminalCommand {
+  const args: string[] = [];
+  if (config.modeId === "bypassPermissions") {
+    args.push("--dangerously-skip-permissions");
+  }
+  if (config.model) args.push("--model", config.model);
+  // mode mapping: default → nothing, plan → --plan, etc.
+  return { command: "claude", args, env: {} };
+}
+
+buildTerminalResumeCommand(handle: AgentPersistenceHandle): TerminalCommand {
+  return {
+    command: "claude",
+    args: ["--resume", handle.sessionId],
+    env: {},
+  };
+}
+```
+
+**Codex** (`packages/server/src/server/agent/providers/codex-app-server-agent.ts`):
+```typescript
+buildTerminalCreateCommand(config: AgentSessionConfig): TerminalCommand {
+  const args: string[] = [];
+  if (config.model) args.push("--model", config.model);
+  if (config.modeId) args.push("--approval-mode", config.modeId);
+  return { command: "codex", args, env: {} };
+}
+
+buildTerminalResumeCommand(handle: AgentPersistenceHandle): TerminalCommand {
+  return {
+    command: "codex",
+    args: ["--resume", handle.nativeHandle ?? handle.sessionId],
+    env: {},
+  };
+}
+```
+
+**OpenCode** (`packages/server/src/server/agent/providers/opencode-agent.ts`):
+```typescript
+buildTerminalCreateCommand(config: AgentSessionConfig): TerminalCommand {
+  return { command: "opencode", args: [], env: {} };
+}
+// No resume support for OpenCode initially
+```
+
+Capabilities for each provider:
+- Claude: `supportsTerminalMode: true`
+- Codex: `supportsTerminalMode: true`
+- OpenCode: `supportsTerminalMode: true`
+
+#### 1.7 Handle terminal agent creation in `AgentManager.createAgent()`
+
+**File:** `packages/server/src/server/agent/agent-manager.ts`
+
+When `config.terminal === true`:
+1. Do NOT call `client.createSession()` — there is no managed session
+2. Call `client.buildTerminalCreateCommand(config)` to get the command
+3. Create a `TerminalSession` via `terminalManager.createTerminal()` with the command
+4. Register the agent with `terminal: true`, `lifecycle: "idle"`, `session: null`
+5. Store the terminal ID in the agent's metadata or a new field
+6. The agent's persistence handle can be populated later (the CLI will create its own session file)
+
+```typescript
+async createAgent(config: AgentSessionConfig, agentId?: string, options?: { labels?: Record<string, string> }): Promise<ManagedAgent> {
+  const resolvedAgentId = validateAgentId(agentId ?? this.idFactory(), "createAgent");
+  const normalizedConfig = await this.normalizeConfig(config);
+  const client = this.requireClient(normalizedConfig.provider);
+
+  if (normalizedConfig.terminal) {
+    // Terminal mode — no managed session, just build the command
+    const buildCmd = client.buildTerminalCreateCommand;
+    if (!buildCmd) {
+      throw new Error(`Provider '${normalizedConfig.provider}' does not support terminal mode`);
+    }
+    const cmd = buildCmd.call(client, normalizedConfig);
+    return this.registerTerminalAgent(resolvedAgentId, normalizedConfig, cmd, {
+      labels: options?.labels,
+    });
+  }
+
+  // ...existing managed agent flow...
+}
+```
+
+New method `registerTerminalAgent()`:
+- Creates a ManagedAgent with `terminal: true`
+- Stores the `TerminalCommand` in agent metadata for later use (resume, reconnect)
+- Sets lifecycle to `"idle"` (the terminal itself manages the agent's internal state)
+- Does NOT have an `AgentSession` — the `session` field is `null` (like closed agents)
+- Broadcasts `agent_state` event so clients know about it
+
+#### 1.8 New message: create terminal for agent
+
+The client needs a way to request a terminal for a terminal agent. Options:
+
+**Option A:** Extend `createTerminal` to accept an agent ID. When provided, the server looks up the agent, gets the command, and creates a terminal pre-configured with that command.
+
+**Option B:** New message type `create_terminal_agent_request` that combines agent creation + terminal creation in one step.
+
+**Recommendation: Option A.** Add optional `agentId` to `CreateTerminalRequestMessage`. If provided:
+- Look up the agent (must be a terminal agent)
+- Use the agent's stored command to create the terminal
+- Associate the terminal with the agent
+
+**File:** `packages/server/src/shared/messages.ts`
+
+```typescript
+const CreateTerminalRequestMessageSchema = z.object({
+  type: z.literal("create_terminal_request"),
+  cwd: z.string(),
+  name: z.string().optional(),
+  agentId: z.string().optional(),  // NEW — if provided, create terminal for this terminal agent
+  requestId: z.string(),
+});
+```
+
+#### 1.9 Terminal → Agent lifecycle binding
+
+When a terminal associated with a terminal agent exits:
+- Set agent lifecycle to `"closed"`
+- Attempt to detect the agent's session file for persistence handle
+- Broadcast state update
+
+When a terminal agent is opened from the sessions page:
+- Server calls `buildTerminalResumeCommand(handle)` if persistence handle exists
+- Otherwise calls `buildTerminalCreateCommand(config)`
+- Creates a new terminal with that command
+
+#### 1.10 Extend `createTerminal()` to support command + args
+
+**File:** `packages/server/src/terminal/terminal.ts`
+
+```typescript
+export interface CreateTerminalOptions {
+  cwd: string;
+  shell?: string;
+  env?: Record<string, string>;
+  rows?: number;
+  cols?: number;
+  name?: string;
+  command?: string;   // NEW — if provided, run this instead of shell
+  args?: string[];    // NEW — arguments for command
+}
+```
+
+In `createTerminal()`:
+```typescript
+const spawnCommand = options.command ?? shell;
+const spawnArgs = options.command ? (options.args ?? []) : [];
+
+const ptyProcess = pty.spawn(spawnCommand, spawnArgs, {
+  name: "xterm-256color",
+  cols, rows, cwd,
+  env: { ...process.env, ...env, TERM: "xterm-256color" },
+});
+```
+
+---
+
+### Phase 2: App — Draft UI & Terminal Toggle
+
+#### 2.1 Add terminal toggle to draft tab
+
+**File:** `packages/app/src/screens/workspace/workspace-draft-agent-tab.tsx`
+
+Add a toggle switch in the draft UI: **"Chat" / "Terminal"**
+
+State:
+```typescript
+const [isTerminalMode, setIsTerminalMode] = useState(false);
+```
+
+The toggle should be persistent per draft (stored in the draft store or as a preference).
+
+When terminal mode is selected:
+- The provider/model pickers still work (same UI)
+- The mode picker still works
+- The "send" button label changes to "Launch" or "Start"
+- The initial prompt input may be hidden or optional (terminal agents don't need an initial prompt — the user types directly into the TUI)
+
+#### 2.2 Modify agent creation to pass `terminal: true`
+
+When the user submits a draft in terminal mode:
+
+```typescript
+const config: AgentSessionConfig = {
+  provider: selectedProvider,
+  cwd: workspaceId,
+  model: selectedModel,
+  modeId: selectedMode,
+  terminal: true,  // NEW
+};
+```
+
+The `CreateAgentRequestMessage` already carries `config`, so no new wire message needed.
+
+#### 2.3 Terminal mode in `AgentStatusBar`
+
+**File:** `packages/app/src/components/agent-status-bar.tsx`
+
+When rendering a draft's status bar, filter the capability:
+- If `supportsTerminalMode` is false for a provider, disable the terminal toggle when that provider is selected
+- The terminal toggle can live next to the provider selector or as a segmented control above the input area
+
+---
+
+### Phase 3: App — Agent Panel Rendering
+
+#### 3.1 Branch rendering in `AgentPanel`
+
+**File:** `packages/app/src/panels/agent-panel.tsx`
+
+```typescript
+function AgentPanelContent({ agentId, ... }) {
+  const agent = useAgentState(agentId);
+
+  if (agent?.terminal) {
+    return <TerminalAgentPanel agentId={agentId} agent={agent} />;
+  }
+
+  return <AgentPanelBody agent={agent} ... />;
+}
+```
+
+#### 3.2 New component: `TerminalAgentPanel`
+
+**File:** `packages/app/src/panels/terminal-agent-panel.tsx` (new file)
+
+This component:
+1. Gets the terminal ID associated with the agent (from agent metadata or a new field)
+2. Renders a `TerminalPane` connected to that terminal session
+3. If no terminal exists yet (agent from sessions page), requests terminal creation via `createTerminal({ agentId })`
+4. Handles terminal exit → agent close lifecycle
+
+Essentially: it's the existing `TerminalPane` component, but associated with an agent entity instead of a standalone terminal.
+
+#### 3.3 Tab descriptor for terminal agents
+
+**File:** `packages/app/src/panels/agent-panel.tsx` → `useAgentPanelDescriptor`
+
+The tab descriptor (icon, label) already comes from the agent's provider. Terminal agents get the same icon/label as managed agents — that's the whole point. No changes needed here unless we want a "terminal" badge.
+
+Optional: add a small terminal icon badge to distinguish terminal agents from managed agents in the tab bar.
+
+---
+
+### Phase 4: Sessions Page
+
+#### 4.1 Terminal agents appear in sessions list
+
+No changes needed for listing — terminal agents are real agents, they already show up via `AgentManager.getAgents()`.
+
+#### 4.2 Opening a terminal agent from sessions
+
+**File:** `packages/app/src/screens/sessions/` (sessions screen)
+
+When the user clicks a closed terminal agent:
+1. Server calls `buildTerminalResumeCommand(handle)` if persistence exists
+2. Creates a new terminal with that command
+3. Opens agent tab in workspace
+
+If no persistence handle (session was ephemeral), show "Start new session" which calls `buildTerminalCreateCommand(config)`.
+
+---
+
+### Phase 5: CLI Gating
+
+#### 5.1 `paseo send` — error for terminal agents
+
+**File:** `packages/cli/src/commands/send.ts`
+
+```typescript
+if (agent.terminal) {
+  throw new Error("Cannot send messages to terminal agents. Open the terminal in the UI instead.");
+}
+```
+
+#### 5.2 `paseo run` — could support `--terminal` flag (future)
+
+Not in v1. For now, `paseo run` always creates managed agents. Terminal mode is UI-only.
+
+#### 5.3 `paseo ls` — show terminal flag
+
+Add a `terminal` column or badge to `paseo ls` output so users can distinguish terminal agents.
+
+---

+
+## Implementation Phases & Agent Assignments
+
+### Phase 1: Server data model (1 agent)
+- Add `terminal` to types, schemas, and agent manager
+- Add `TerminalCommand` type and `buildTerminalCreateCommand`/`buildTerminalResumeCommand` to `AgentClient`
+- Add `supportsTerminalMode` capability flag
+- Extend `createTerminal()` to support command+args
+- Implement terminal agent creation flow in `AgentManager`
+- Wire terminal exit → agent close lifecycle
+- Implement command builders in Claude, Codex, OpenCode providers
+- Typecheck must pass
+
+### Phase 2: App draft UI + terminal toggle (1 agent)
+- Add terminal mode toggle to `workspace-draft-agent-tab.tsx`
+- Pass `terminal: true` in config when toggle is on
+- Filter toggle based on `supportsTerminalMode` capability
+- Persist toggle preference
+- Typecheck must pass
+
+### Phase 3: App panel rendering (1 agent)
+- Branch `AgentPanelContent` on `agent.terminal`
+- Create `TerminalAgentPanel` component
+- Handle terminal creation for agent on open
+- Handle terminal exit lifecycle
+- Typecheck must pass
+
+### Phase 4: Sessions page + CLI gating (1 agent)
+- Terminal agents show in sessions with badge
+- Opening from sessions resumes or creates terminal
+- `paseo send` errors for terminal agents
+- `paseo ls` shows terminal badge
+- Typecheck must pass
+
+---
+
+## Feature Interaction Guards
+
+Terminal agents are explicitly excluded from automated dispatch paths:
+
+- **LoopService**: `buildWorkerConfig` and `buildVerifierConfig` set `terminal: false`
+- **ScheduleService**: `executeSchedule` rejects terminal agents with a clear error for agent-targeted schedules; new-agent schedules set `terminal: false`
+- **Voice mode / `handleSendAgentMessage`**: Guarded by `getStructuredSendRejection()` before send
+- **CLI `paseo send`**: Returns error for terminal agents
+- **MCP agent creation**: Programmatic paths don't pass `terminal: true`
+
+All session-specific operations (`runAgent`, `streamAgent`, `setMode`, `cancelAgentRun`, etc.) are guarded by the centralized `requireSessionAgent()` which rejects terminal agents.
+
+## What This Does NOT Change
+
+- The existing managed agent flow is untouched
+- Terminal sessions (non-agent) still work as before
+- The `AgentSession` interface is unchanged
+- Mobile experience is unchanged (terminal mode is web/desktop only for now)
+- No new providers are added (existing providers gain terminal command builders)
+- No hooks, no env injection, no process tree detection (v1 keeps it simple)
+
+## Future Work (Not In This Plan)
+
+- Auto-detect agent type from PTY process tree (for standalone terminals)
+- "Convert to chat" / "Convert to terminal" actions
+- Terminal title/icon from OSC sequences
+- `paseo run --terminal` CLI support
+- Mobile terminal mode (if xterm.js works well enough on mobile web)
+- Gemini / Aider / Goose provider definitions (terminal-only providers)
