Subject: [PATCH 07/12] feat(api): register queue routes and add
 push/stats/peek/purge handlers

Implements POST /queues/{name}/push, GET /queues/{name}/stats,
GET /queues/{name}/peek, and DELETE /queues/{name} endpoints,
including queue name validation (alphanumeric + hyphens, max 64 chars).

Subject: [PATCH 09/12] feat(scheduler): add Queue trigger type wired into
 strategy, API, and CLI

Adds TriggerConfig::Queue variant, QueueStrategy factory wiring in
create_strategy(), API validation, template variables (queue_name,
queue_task_id, queue_priority), client methods, and CLI subcommands
(queue-stats, queue-peek, queue-purge) with --trigger-type queue support.

From a965cff0ed54bb756160e0acb4be411b76d0c744 Mon Sep 17 00:00:00 2001
From: Geoff Johnson <geoff.jay@gmail.com>
Date: Sat, 28 Mar 2026 13:39:04 -0700
Subject: [PATCH 11/12] test+docs: add comprehensive tests and documentation
 for queue trigger

Adds unit tests for queue storage (FIFO, priority ordering, visibility
timeout, retry/dead-letter, stats, peek, purge), QueueStrategy unit
tests, 8 integration tests in queue_trigger.rs, CLI argument parsing
tests for queue subcommands, and docs/public/queue-trigger.md covering
API, CLI, template variables, retry semantics, and architecture patterns.

+# Queue-Based Trigger
+
+The `queue` trigger type allows workflows to consume tasks from a named internal
+queue. Producers push work via the REST API; the workflow's agent processes items
+one at a time with visibility timeout and automatic retry semantics.
+
+## Overview
+
+```

+```
+
+Tasks are dequeued in **priority-descending, FIFO** order:
+
+- Tasks with higher `priority` values are processed first.
+- Among tasks with equal priority, the oldest is taken first.
+
+While a task is processing, it is invisible to other consumers for
+`visibility_timeout_secs` seconds (default 300 / 5 minutes).
+
+---
+
+## Configuration
+
+### `TriggerConfig` variant
+
+```json
+{
+  "type": "queue",
+  "queue_name": "work-items",
+  "poll_interval_secs": 5,
+  "visibility_timeout_secs": 300
+}
+```
+
+| Field                    | Type     | Required | Default | Description                                         |
+|--------------------------|----------|----------|---------|-----------------------------------------------------|
+| `queue_name`             | `string` | yes      | —       | Name of the queue to consume from                   |
+| `poll_interval_secs`     | `u64`    | no       | `5`     | How often to poll when the queue is empty (seconds) |
+| `visibility_timeout_secs`| `u64`    | no       | `300`   | Visibility timeout for dequeued tasks (seconds)     |
+
+**Queue name rules:** alphanumeric characters and hyphens only, 1–64 characters.
+
+---
+
+## Creating a Queue-Triggered Workflow
+
+### Via REST API
+
+```bash
+curl -X POST http://localhost:7006/workflows \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "name": "report-processor",
+    "agent_id": "<agent-uuid>",
+    "trigger_config": {
+      "type": "queue",
+      "queue_name": "reports",
+      "poll_interval_secs": 5,
+      "visibility_timeout_secs": 300
+    },
+    "prompt_template": "Process report: {{title}}\n\nDetails: {{body}}\n\nQueue: {{queue_name}}, Task ID: {{queue_task_id}}"
+  }'
+```
+
+### Via CLI
+
+```bash
+agent orchestrator create-workflow \
+  --name report-processor \
+  --agent-name reporter \
+  --trigger-type queue \
+  --queue-name reports \
+  --queue-poll-interval 5 \
+  --queue-visibility-timeout 300 \
+  --prompt-template "Process report: {{title}}\n\nDetails: {{body}}"
+```
+
+---
+
+## Pushing Tasks
+
+### REST API
+
+```bash
+curl -X POST http://localhost:7006/queues/reports/push \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "title": "Process Q4 report",
+    "body": "{\"report_id\": 42, \"format\": \"pdf\"}",
+    "priority": 5
+  }'
+```
+
+**Response (201 Created):**
+
+```json
+{
+  "id": "3fa85f64-5717-4562-b3fc-2c963f66afa6",
+  "queue_name": "reports",
+  "status": "pending",
+  "created_at": "2026-03-28T12:00:00Z"
+}
+```
+
+| Field      | Type     | Required | Default | Description                          |
+|------------|----------|----------|---------|--------------------------------------|
+| `title`    | `string` | yes      | —       | Short description of the task        |
+| `body`     | `string` | no       | `""`    | Task payload (JSON, text, etc.)      |
+| `priority` | `i32`    | no       | `0`     | Higher values processed first        |
+
+---
+
+## Queue Management
+
+### Statistics
+
+```bash
+# REST
+GET /queues/{name}/stats
+
+# CLI
+agent orchestrator queue-stats reports
+```
+
+**Response:**
+
+```json
+{
+  "pending":    3,
+  "processing": 1,
+  "completed":  42,
+  "failed":     2,
+  "dead":       1
+}
+```
+
+### Peek (non-destructive view)
+
+```bash
+# REST
+GET /queues/{name}/peek?limit=10
+
+# CLI
+agent orchestrator queue-peek reports --limit 5
+```
+
+Returns up to `limit` pending tasks without claiming them. Default limit: 10, max: 100.
+
+### Purge
+
+```bash
+# REST
+DELETE /queues/{name}
+
+# CLI
+agent orchestrator queue-purge reports
+```
+
+**Response:**
+
+```json
+{ "deleted": 7 }
+```
+
+Removes **all** tasks from the queue regardless of status. Use with care.
+
+---
+
+## Template Variables
+
+Queue workflows have access to these `{{placeholder}}` variables in addition to
+standard task fields:
+
+| Variable          | Description                             |
+|-------------------|-----------------------------------------|
+| `{{queue_name}}`  | Name of the queue the task came from    |
+| `{{queue_task_id}}`| Internal UUID of the queue task        |
+| `{{queue_priority}}`| Priority value assigned at push time  |
+| `{{title}}`       | Task title (from push request)          |
+| `{{body}}`        | Task body / payload (from push request) |
+
+---
+
+## Retry and Dead-Letter Semantics
+
+When a task fails to dispatch (agent unavailable, network error, etc.):
+
+1. The task's `retry_count` is incremented.
+2. If `retry_count < max_retries` (default 3), the task is moved back to `pending`.
+3. If `retry_count >= max_retries`, the task is moved to `dead` (dead letter).
+
+Dead-letter tasks are not retried automatically. They remain in the queue for
+inspection via `queue-stats` and `queue-peek` (visible in stats but not in peek,
+which only shows pending tasks). Purge the queue to remove them.
+
+---
+
+## Architecture Patterns
+
+### Simple background work queue
+
+```
+Agent A (producer) → POST /queues/bg-tasks/push
+Agent B (worker)   → queue trigger workflow consuming bg-tasks
+```
+
+### Priority queue for tiered processing
+
+```bash
+# High priority bug fix
+curl -X POST .../queues/work/push -d '{"title":"Critical bug","priority":100}'
+
+# Normal feature request
+curl -X POST .../queues/work/push -d '{"title":"New feature","priority":10}'
+```
+
+### Multi-producer pattern with webhooks feeding the queue
+
+```
+GitHub webhook → webhook-workflow → POST /queues/gh-issues/push
+Linear webhook → webhook-workflow → POST /queues/gh-issues/push
+Queue workflow → consumes gh-issues → agent processes unified stream
+```
+
+---
+
+## Troubleshooting
+
+**Tasks are not being picked up:**
+- Verify the workflow is enabled: `agent orchestrator get-workflow <id>`
+- Check that `queue_name` in the trigger config matches the name used in `POST /queues/{name}/push`
+- Confirm the agent is running: `agent orchestrator list-agents`
+
+**Tasks stay in `processing` state:**
+- The agent may be busy or disconnected.
+- After `visibility_timeout_secs` have elapsed, the task will become visible again
+  and be retried automatically (up to `max_retries`).
+
+**Queue grows unboundedly:**
+- The consumer workflow may be disabled or the agent may be unavailable.
+- Monitor with `queue-stats` and adjust producer rate.
+
+**Dead-letter tasks:**
+- Check agent logs for error details.
+- Use `queue-purge` to clear dead-letter tasks after investigation.

Subject: [PATCH 12/12] fix(scheduler): wire queue task lifecycle into
 notify_complete

Complete the QueueStrategy lifecycle by calling complete_queue_task or
fail_queue_task in notify_complete when a queue-sourced dispatch finishes.
The source_id format 'queue:{name}:{id}' is parsed to extract the task ID.
This also resolves the clippy dead_code warning on these storage methods.
