fix(plugin): lift calendarScheduler to module scope (multi-register singleton)

Trying the prior multi-agent-handle fix in dind-t2 surfaced a second bug
that PR #7 didn't reach: `harborforge_calendar_status` still returned
`Calendar scheduler not running` even though the gateway log showed the
scheduler had started 30+ seconds before the agent's call.

## Root cause

`register()` is invoked once per agent — `grep -c "HarborForge plugin
registered" /tmp/gw-stdout.log` reports 5 for a 5-agent claw. Every
invocation creates its own `let calendarScheduler` closure binding. But
`gateway_start` fires once and we only call `startCalendarScheduler()`
through that single hook, so exactly one of the five closures sees the
handle and the other four keep their bindings at `null`.

The host's tool router picks one of the five duplicate
`harborforge_calendar_status` registrations to dispatch to — most of the
time it's one of the four "null" closures, which is why every wakeup the
agent saw `Calendar scheduler not running`.

## Fix

Lift `let calendarScheduler` out of `register()` and into module scope.
All five register-call closures now reference the same binding; once the
single `gateway_start` initialises it, every tool sees it.

`startCalendarScheduler()` now early-returns when `calendarScheduler` is
already set, so duplicate `gateway_start` firings (if the host ever does
that) don't double-install intervals.

Bumps version 0.3.2 → 0.3.3.

 # HarborForge OpenClaw Plugin
 
-OpenClaw 插件，将服务器遥测数据流式传输到 HarborForge Monitor。
+OpenClaw plugin that exposes OpenClaw-side metadata to the HarborForge Monitor, provides an optional local Monitor bridge, drives the HarborForge Calendar scheduler, and can optionally install the `hf` CLI.
 
-## 项目结构
+Part of the [HarborForge](../README.md) platform.
 
-```
+- Role: OpenClaw integration layer for HarborForge (registered plugin id: `harbor-forge`).
+- Talks to the HarborForge backend (`backendUrl`, default `https://monitor.hangman-lab.top`) for Calendar APIs.
+- Talks to a local HarborForge.Monitor bridge over `127.0.0.1:<monitor_port>` (no fixed default; commonly `9100`).
+
+## Current State
+
+- Plugin registration id: `harbor-forge` (was `harborforge-monitor`)
+- Plugin version: `0.2.0` (package manifests); telemetry reports `pluginVersion` `0.3.1`
+- Legacy sidecar `server/` architecture removed — telemetry is served directly by the plugin
+- Monitor bridge runs over the local `monitor_port`
+- Calendar scheduler integration (PLG-CAL-001 / 002 / 004)
+- Installer supports `--install-cli` and an optional managed Monitor (`--install-monitor`)
+- `skills/hf/` is installed only with `--install-cli`

+If `managedMonitor` points to an installed HarborForge.Monitor binary, the `gateway_start` hook spawns it (passing `--backend-url`, `--identifier`, `--api-key`, `--monitor-port`, `--report-interval`, `--log-level` from the plugin config) and `gateway_stop` terminates it. Use `install.mjs --install-monitor yes` to build and wire this automatically.
 
-### 构建插件
+## Calendar Scheduler
+
+When `calendarEnabled` is true, on gateway start the plugin starts a Calendar scheduler that heartbeats the backend (`/calendar/agent/heartbeat`, `/calendar/agent/status`, `/calendar/agent/notify`) to receive and run scheduled TimeSlots, waking/spawning agents via the OpenClaw `spawn` API (with a notification fallback). Scheduler state is persisted to a state file; gateway restarts can be requested by the backend (PLG-CAL-004).

+# CalendarScheduler Refactor Plan (v2)
+
+> Updated 2026-04-19 based on architecture discussion with hang
+
+## Current Issues
+
+1. `process.env.AGENT_ID` doesn't exist in plugins subprocess — always 'unknown'
+2. Heartbeat is per-agent but should be per-claw-instance (global)
+3. Scheduler only handles one agent — should manage all agents on this instance
+4. wakeAgent used api.spawn (non-existent) → now uses dispatchInboundMessage (verified)
+
+## Target Design
+
+### Plugin State
+
+```typescript
+// Local schedule cache: { agentId → [slots] }
+const schedules: Map<string, CalendarSlotResponse[]> = new Map();
+```
+
+### Sync Flow (every 5 min)
+
+```
+1. GET /calendar/sync?claw_identifier=xxx
+   - First call: server returns full { agentId → [slots] }
+   - Subsequent: server returns diff since last sync
+2. Update local schedules map
+3. Scan schedules for due slots:
+   for each agentId in schedules:
+     if has slot where scheduled_at <= now && status == not_started:
+       getAgentStatus(agentId, clawIdentifier) → busy?
+       if not busy → wakeAgent(agentId)
+```
+
+### Heartbeat (every 60s)
+
+Simplified to liveness ping only:
+```
+POST /monitor/server/heartbeat
+  claw_identifier: xxx
+  → server returns empty/ack
+```
+
+No slot data in heartbeat response.
+
+### Wake Flow
+
+```
+dispatchInboundMessage:
+  SessionKey: agent:{agentId}:hf-wakeup
+  Body: "You have due slots. Follow the hf-wakeup workflow of skill hf-hangman-lab to proceed. Only reply WAKEUP_OK in this session."
+
+Agent reads workflow → calls hf tools → sets own status to busy
+```
+
+### Agent ID Resolution
+
+- **Sync**: agentId comes from server response (dict keys)
+- **Wake**: agentId from local schedules dict key
+- **Tool calls by agent**: agentId from tool ctx (same as padded-cell)
+
+## Backend API Changes Needed
+
+### New: GET /calendar/sync
+
+```
+GET /calendar/sync?claw_identifier=xxx
+Headers: X-Claw-Identifier
+
+Response (first call):
+{
+  "full": true,
+  "schedules": {
+    "developer": [slot1, slot2, ...],
+    "operator": [slot3, ...]
+  },
+  "syncToken": "abc123"
+}
+
+Response (subsequent, with ?since=abc123):
+{
+  "full": false,
+  "diff": [
+    { "op": "add", "agent": "developer", "slot": {...} },
+    { "op": "update", "agent": "developer", "slotId": 5, "patch": {...} },
+    { "op": "remove", "agent": "operator", "slotId": 3 }
+  ],
+  "syncToken": "def456"
+}
+```
+
+### Existing: POST /calendar/agent/status
+
+Keep as-is but ensure it accepts agentId + clawIdentifier as params:
+```
+POST /calendar/agent/status
+  { agent_id, claw_identifier, status }
+```
+
+## Implementation Order
+
+1. Backend: Add /calendar/sync endpoint
+2. Plugin: Replace CalendarBridgeClient single-agent design with multi-agent
+3. Plugin: Replace CalendarScheduler with new sync+check loop
+4. Plugin: wakeAgent uses dispatchInboundMessage (done)
+5. Plugin: Tool handlers get agentId from ctx (like padded-cell)
+
+## Files to Change
+
+### Backend (HarborForge.Backend)
+- New route: `/calendar/sync`
+- New service: schedule diff tracking per claw_identifier
+
+### Plugin
+- `plugin/calendar/calendar-bridge.ts` — remove agentId binding, add sync()
+- `plugin/calendar/scheduler.ts` — rewrite to multi-agent sync+check
+- `plugin/calendar/schedule-cache.ts` — already exists, adapt to multi-agent
+- `plugin/index.ts` — update wakeAgent, getAgentStatus to accept agentId

+# PLG-CAL-001 — Calendar Heartbeat Format Specification
+
+> **Task:** HarborForge OpenclawPlugin / Monitor 联动  
+> **Subtask:** PLG-CAL-001 — 插件侧定义 Calendar 心跳请求格式  
+> **Status:** ✅ Implemented (types + client + spec)  
+> **Date:** 2026-04-01
+
+---
+
+## Overview
+
+This document specifies the request/response format for the Calendar heartbeat
+communication between the OpenClaw HarborForge plugin and the HarborForge backend.
+
+Heartbeat direction: **Plugin → Backend**
+
+The plugin sends a heartbeat every minute (aligned with the existing Monitor
+heartbeat interval). The backend returns today's pending TimeSlots for the agent.
+
+---
+
+## 1. How `claw_identifier` is Determined
+
+`claw_identifier` identifies the server/claw instance. It is the same value used
+in the Monitor heartbeat system (`MonitoredServer.identifier`).
+
+**Priority order:**
+
+1. **`config.identifier`** — if set in the plugin config (`harbor-forge.identifier`)
+2. **`os.hostname()`** — auto-detected from the machine hostname (fallback)
+
+```typescript
+// In plugin/calendar/calendar-bridge.ts
+const clawIdentifier = baseConfig.identifier || hostname();
+```
+
+---
+
+## 2. How `agent_id` is Determined
+
+`agent_id` is the OpenClaw agent identifier (`$AGENT_ID`).
+
+- Set by OpenClaw at agent startup as an environment variable
+- The plugin reads it via `process.env.AGENT_ID`
+- Globally unique within a single OpenClaw gateway deployment
+
+```typescript
+// In plugin/index.ts (caller)
+const agentId = process.env.AGENT_ID || 'unknown';
+```
+
+---
+
+## 3. Heartbeat Request
+
+**Endpoint:** `GET /calendar/agent/heartbeat`
+
+### Headers
+
+| Header | Value | Notes |
+|--------|-------|-------|
+| `Content-Type` | `application/json` | Always set |
+| `X-Agent-ID` | `$AGENT_ID` | OpenClaw agent identifier |
+| `X-Claw-Identifier` | `claw_identifier` | Server identifier |
+
+### Request Body (JSON)
+
+```json
+{
+  "claw_identifier": "srv1390517",
+  "agent_id": "developer"
+}
+```
+
+### Field Definitions
+
+| Field | Type | Source | Notes |
+|-------|------|--------|-------|
+| `claw_identifier` | string | Plugin config or `hostname()` | Identifies the OpenClaw server instance |

+
+## 5. Slot Update Requests (Plugin → Backend after execution)
+
+After attending / finishing / deferring a slot, the plugin calls:
+
+**Real slot:** `PATCH /calendar/slots/{slot_id}/agent-update`
+**Virtual slot:** `PATCH /calendar/slots/virtual/{virtual_id}/agent-update`
+
+### Headers
+
+Same as heartbeat (see §3).
+
+### Request Body
+
+```json
+{
+  "status": "ongoing",
+  "started_at": "09:02:31",
+  "actual_duration": null
+}
+```
+
+| Field | Type | Required | Notes |
+|-------|------|----------|-------|
+| `status` | `SlotStatus` | **Required** | New status after agent action |
+| `started_at` | string | On attending | ISO time `HH:MM:SS` |
+| `actual_duration` | number | On finishing | Real minutes |
+
+### Status Transition Values
+
+| Action | `status` value |
+|--------|---------------|
+| Agent begins slot | `ongoing` |
+| Agent finishes slot | `finished` |
+| Agent defers slot | `deferred` |
+| Agent aborts slot | `aborted` |
+| Agent pauses slot | `paused` |
+
+---
+
+## 6. Backend Endpoint Summary
+
+| Method | Path | Auth | Description |
+|--------|------|------|-------------|
+| GET | `/calendar/agent/heartbeat` | X-Agent-ID + X-Claw-Identifier | Fetch pending slots for today |
+| PATCH | `/calendar/slots/{id}/agent-update` | X-Agent-ID + X-Claw-Identifier | Update real slot status |
+| PATCH | `/calendar/slots/virtual/{vid}/agent-update` | X-Agent-ID + X-Claw-Identifier | Update virtual slot status |
+| POST | `/calendar/agent/status` | X-Agent-ID + X-Claw-Identifier | Report agent status change |
+
+---
+
+## 7. Error Handling
+
+- **Backend unreachable:** Plugin logs warning, returns `null` from heartbeat.  
+  Agent continues to operate without Calendar integration.
+- **Invalid credentials (401/403):** Logged as error. No retry on same interval.
+- **Rate limiting (429):** Plugin should mark agent as `Exhausted` and not retry
+  until the `Retry-After` header indicates.
+
+---
+
+## 8. TypeScript Reference
+
+Full type definitions are in `plugin/calendar/types.ts`:
+
+```typescript
+// Request
+interface CalendarHeartbeatRequest {
+  claw_identifier: string;
+  agent_id: string;
+}
+
+// Response
+interface CalendarHeartbeatResponse {
+  slots: CalendarSlotResponse[];
+  agent_status: AgentStatusValue;
+  message?: string;
+}
+
+// Slot update
+interface SlotAgentUpdate {
+  status: SlotStatus;
+  started_at?: string;   // ISO time HH:MM:SS
+  actual_duration?: number;
+}

 ## Current design
 
-The plugin uses:
+The plugin and Monitor communicate over a local bridge port (`monitor_port` / `MONITOR_PORT`).
 
-- **HTTP heartbeat** to `/monitor/server/heartbeat-v2`
-- **API Key authentication** via `X-API-Key`
-- **Gateway lifecycle hooks**: `gateway_start` / `gateway_stop`
+### Data flow
+
+1. **Monitor → Plugin** (GET): Plugin queries `GET /telemetry` on the bridge for host hardware data.
+2. **Plugin → Monitor** (POST): Plugin pushes OpenClaw metadata via `POST /openclaw` to the bridge.
+3. **Monitor → Backend**: Monitor heartbeats to `POST /monitor/server/heartbeat-v2` with `X-API-Key`, enriched with any available OpenClaw metadata.
+
+### Bridge endpoints (on Monitor, 127.0.0.1:MONITOR_PORT)
+
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `/health` | GET | Health check, returns monitor version and identifier |
+| `/telemetry` | GET | Latest hardware telemetry snapshot |
+| `/openclaw` | POST | Receive OpenClaw metadata from plugin |
+
+### Plugin behavior
+
+- On `gateway_start`, plugin begins periodic metadata push (aligned with `reportIntervalSec`).
+- Initial push is delayed 2s to allow Monitor bridge startup.
+- If bridge is unreachable, pushes fail silently. Plugin remains fully functional.
+- On `gateway_stop`, periodic push is stopped.
 
 ## No longer used
 
 The following design has been retired:
 
-- challenge UUID
-- RSA public key fetch
-- encrypted handshake payload
-- WebSocket telemetry
+- challenge UUID / RSA handshake / WebSocket telemetry
+- Plugin-side `server/` sidecar process
 
-## Runtime flow
-
-1. Gateway loads `harborforge-monitor`
-2. Plugin reads config from OpenClaw plugin config
-3. On `gateway_start`, plugin launches `server/telemetry.mjs`
-4. Sidecar collects:
-   - system metrics
-   - OpenClaw version
-   - plugin version
-   - configured agents
-5. Sidecar posts telemetry to backend with `X-API-Key`
-

+ * Background
+ * ----------
+ * The old single-agent path used `CalendarScheduler` which kept a "current

+ * In multi-agent mode the plugin doesn't own a single cursor — one plugin

+ * with `calendarScheduler.<method> is not a function`.
+ *
+ * This handle restores the same surface area (`isRunning / getCurrentSlot /
+ * completeCurrentSlot / …`) but resolves the "current slot" per caller via
+ * the agentId/sessionKey supplied by the OpenClaw tool-factory context. The
+ * scheduler records the slot it just dispatched to each agent in
+ * {@link recordWoken}; the tool resolves the caller, looks up the last woken
+ * slot, and PATCHes the backend via the shared bridge.
+ *
+ * Tools must pass the calling agentId (from `OpenClawPluginToolContext.agentId`)

+# hf - HarborForge CLI
+
+`hf` is the Go-based CLI for HarborForge. It manages users, projects, tasks, milestones, meetings, support tickets, proposals, and server monitoring.
+
+## Quick Start
+
+```bash
+# See all available commands (including those you may not have permission for)
+hf --help
+
+# See only the commands you're permitted to use
+hf --help-brief
+
+# Check API health
+hf health
+
+# Show CLI version
+hf version
+```
+
+## Configuration
+
+```bash
+# Set the HarborForge API URL
+hf config --url https://your-harborforge.example.com
+
+# View current config
+hf config
+```
+
+## Usage Tips
+
+- Use `hf --help-brief` to quickly see what you can do — it hides commands you don't have permission for.
+- Use `hf <group> --help` for the full subcommand list of any group (e.g. `hf task --help`).
+- Add `--json` to any command for machine-readable JSON output.
+- Resources use **codes** (not numeric IDs) — e.g. `hf task get TASK-42`.
+
+## Authentication
+
+If `pass_mgr` is available (padded-cell mode), authentication is automatic — no flags needed.
+
+Without `pass_mgr` (manual mode), pass `--token <token>` to authenticated commands.
+
+## Command Groups
+
+| Group       | Description                        |
+|-------------|------------------------------------|
+| `user`      | Manage user accounts               |
+| `role`      | Manage roles and permissions       |
+| `project`   | Manage projects and members        |
+| `milestone` | Manage project milestones          |
+| `task`      | Manage and track tasks             |
+| `meeting`   | Manage meetings and attendance     |
+| `support`   | Manage support tickets             |
+| `propose`   | Manage proposals                   |
+| `monitor`   | Monitor servers and API keys       |
+| `config`    | CLI configuration                  |
+| `health`    | API health check                   |
+| `version`   | Show CLI version                   |
