{"role": "_system_prompt", "content": "You are Kimi Code CLI, an interactive general AI agent running on a user's computer.\n\nYour primary goal is to answer questions and/or finish tasks safely and efficiently, adhering strictly to the following system instructions and the user's requirements, leveraging the available tools flexibly.\n\n\n\n# Prompt and Tool Use\n\nThe user's messages may contain questions and/or task descriptions in natural language, code snippets, logs, file paths, or other forms of information. Read them, understand them and do what the user requested. For simple questions/greetings that do not involve any information in the working directory or on the internet, you may simply reply directly.\n\nWhen handling the user's request, you may call available tools to accomplish the task. When calling tools, do not provide explanations because the tool calls themselves should be self-explanatory. You MUST follow the description of each tool and its parameters when calling tools.\n\nYou have the capability to output any number of tool calls in a single response. If you anticipate making multiple non-interfering tool calls, you are HIGHLY RECOMMENDED to make them in parallel to significantly improve efficiency. This is very important to your performance.\n\nThe results of the tool calls will be returned to you in a tool message. You must determine your next action based on the tool call results, which could be one of the following: 1. Continue working on the task, 2. Inform the user that the task is completed or has failed, or 3. Ask the user for more information.\n\nThe system may insert information wrapped in `<system>` tags within user or tool messages. This information provides supplementary context relevant to the current task \u2014 take it into consideration when determining your next action.\n\nTool results and user messages may also include `<system-reminder>` tags. Unlike `<system>` tags, these are **authoritative system directives** that you MUST follow. They bear no direct relation to the specific tool results or user messages in which they appear. Always read them carefully and comply with their instructions \u2014 they may override or constrain your normal behavior (e.g., restricting you to read-only actions during plan mode).\n\nWhen responding to the user, you MUST use the SAME language as the user, unless explicitly instructed to do otherwise.\n\n# General Guidelines for Coding\n\nWhen building something from scratch, you should:\n\n- Understand the user's requirements.\n- Ask the user for clarification if there is anything unclear.\n- Design the architecture and make a plan for the implementation.\n- Write the code in a modular and maintainable way.\n\nWhen working on an existing codebase, you should:\n\n- Understand the codebase and the user's requirements. Identify the ultimate goal and the most important criteria to achieve the goal.\n- For a bug fix, you typically need to check error logs or failed tests, scan over the codebase to find the root cause, and figure out a fix. If user mentioned any failed tests, you should make sure they pass after the changes.\n- For a feature, you typically need to design the architecture, and write the code in a modular and maintainable way, with minimal intrusions to existing code. Add new tests if the project already has tests.\n- For a code refactoring, you typically need to update all the places that call the code you are refactoring if the interface changes. DO NOT change any existing logic especially in tests, focus only on fixing any errors caused by the interface changes.\n- Make MINIMAL changes to achieve the goal. This is very important to your performance.\n- Follow the coding style of existing code in the project.\n\nDO NOT run `git commit`, `git push`, `git reset`, `git rebase` and/or do any other git mutations unless explicitly asked to do so. Ask for confirmation each time when you need to do git mutations, even if the user has confirmed in earlier conversations.\n\n# General Guidelines for Research and Data Processing\n\nThe user may ask y

The service must handle idle periods when DolphinNG6 (Windows) is down, and auto-recover when NG6 restarts. Currently investigating why existing Prefect deployments aren't working and checking for pre-existing solutions.\n</current_focus>\n\n<environment>\n- **Project Root**: `/mnt/dolphinng5_predict`\n- **Data Source**: DolphinNG6 (Windows) → `/mnt/ng6_data/eigenvalues/YYYY-MM-DD/` (SMB mount)\n- **Hazelcast**: localhost:5701, cluster: `dolphin`\n- **Key Maps**: `DOLPHIN_FEATURES` (eigen scans, EXTF, ACB), `DOLPHIN_SAFETY` (posture)\n- **Python Env**: `/home/dolphin/siloqy_env` (Python 3.12.12, Prefect 3.6.22)\n- **Current Hz Data**: Stale - Scan #7672 from 3 hours ago (12:13:24, current ~15:13)\n- **DolphinNG6 Status**: Likely dead/crashed on Windows host (no new scans)\n</environment>\n\n<completed_tasks>\n- **Path Handling Fix**: Updated `acb_processor_service.py` and `system_watchdog_service.py` to use `dolphin_paths.py` from NG6 for cross-platform Windows/Linux compatibility\n- **Hz Data Flow**: Scan bridge (PID: 3586074) running and pushing eigenvalue scans to `latest_eigen_scan` (when NG6 produces data)\n- **EXTF Service**: Running (PID: 2191130), pushing external factors to Hz\n- **Binance L2 Connectivity**: Verified working via WebSocket test\n- **Code Cleanup**: Removed unnecessary wrapper files, kept original services with minimal path patches\n</completed_tasks>\n\n<active_issues>\n- **DolphinNG6 Down**: No new scan files for 3+ hours. Hz stuck at scan #7672. Requires Windows host restart.\n- **Scan Bridge Prefect Integration**: Attempts to deploy as Prefect flow failing due to version syntax mismatches (Prefect 3.x). Need to check for pre-existing working deployments.\n- **OBF Service Broken**: Has parameter validation error (`assets: Input should be a valid list`). Missing `external_factors` module dependency.\n- **ACB/Watchdog Services**: Path-fixed but not currently running.

{"role":"assistant","content":[{"type":"think","think":"Interesting! The EXTF service (`exf_prefect_final.py`) is using Prefect flows but running as a standalone Python process. It's a hybrid approach:\n1. It defines a Prefect flow\n2. But it's not using Prefect server/worker/deployment\n3. It's essentially \"embedded Prefect\" - using Prefect for task orchestration, logging, and retries, but not for scheduling/deployment management\n\nThis explains why `prefect deployment ls` shows nothing - the flows are not actually deployed to a Prefect server, they're just running as regular Python processes.\n\nThis is actually a valid pattern - you can use Prefect's `@flow` and `@task` decorators without needing a Prefect server. The flows still get logging, task management, and observability, but you don't need the full server infrastructure.\n\nSo for the scan bridge service, the options are:\n\n1. **Keep running standalone** (current): Just use the existing `scan_bridge_service.py` as-is\n2. **Prefect-embedded** (like EXTF): Wrap it with `@flow` decorators for better logging/monitoring\n3. **Full Prefect deployment**: Set up a Prefect server and deploy it properly\n\nGiven that:\n- The current scan bridge is running fine (PID 3586074)\n- EXTF uses the embedded approach\n- Setting up full Prefect server adds complexity\n\nThe best approach might be to:\n1. Keep the current scan bridge running\n2. Maybe add a simple systemd service file for auto-restart\n3. Or use the Prefect-embedded pattern like EXTF for better observability\n\nLet me check what the actual state is and what the user wants to do. The scan bridge is already running, so maybe the task is to:\n1. Make sure it auto-restarts on crash\n2. Make sure it handles NG6 downtime gracefully (idle mode)\n\nThe scan bridge service already has some of this logic built-in.

They're pointing out that Prefect has a mode where the server itself can manage workers without needing a separate systemd service. Let me think about this...\n\nIn Prefect 3.x, there are actually a few different deployment patterns:\n\n1. **Worker mode** (what I set up): You run `prefect worker start --pool dolphin` as a long-running process. This worker polls the Prefect server for work. This is the recommended production pattern.\n\n2. **Server-managed execution**: Prefect server can directly execute flows in subprocesses without a separate worker process. This is less common in production.\n\n3. **Docker/Kubernetes**: Workers run as containers/pods.\n\nThe user is right that in some configurations, you don't need a separate \"daemon\" - the server can manage execution directly. But in the typical production setup for Prefect 3.x, you DO need workers.\n\nLet me check what the actual pattern is in their environment. Looking back:\n- The EXTF service (`exf_prefect_final.py`) runs standalone with `@flow` decorators but isn't actually connected to the Prefect server\n- The Prefect server is running in Docker\n- The `dolphin-paper-trade` deployments exist\n\nSo the question is: does Prefect server need a worker daemon or can it manage flows directly?\n\nIn Prefect 3.x:\n- The server stores flow definitions and schedules\n- Workers actually execute the flows\n- You need at least one worker to execute flows\n\nBUT, there's also `prefect flow-run execute` which can run flows directly...\n\nActually, I think the user might be thinking of Prefect 1.x (where agents were used) or they might be confusing the server with the worker concept.\n\nLet me clarify:\n- Prefect server = API + UI + scheduler\n- Workers = processes that actually run flows\n- You CAN run flows directly without workers using `python myflow.py` but then you don't get the orchestration benefits\n\n\n- The server handles scheduling and state management while workers pick up and execute scheduled runs. In their current setup, the systemd service running `prefect worker start` is what polls the server for work, which is the standard production pattern. Without a worker running, scheduled flows would just sit in the queue indefinitely.

With the server and worker running, you can deploy and run flows from your local machine. 4.1 Local ...Read more\n\n## Self-Hosting Prefect: How to Deploy Prefect on Northflank\n\nPrefect is a **Python workflow orchestration framework**. You write workflows (called flows) as plain Python functions, and Prefect handles the hard parts: retries, scheduling, state tracking, and a UI to watch it all happen.\n\nThis guide walks you through self-hosting Prefect and shows you how to deploy Prefect flows on Northflank.\n\nDevelopers typically reach for Prefect when they need to:\n\n- Orchestrate data pipelines\n\n- Automate ML training or inference jobs\n\n- Schedule recurring tasks\n\n- Manage distributed Python workflows\n\nOn **Northflank**, Prefect gets managed infrastructure without the Kubernetes overhead. Northflank spins up isolated container jobs on-demand for each flow run, while Prefect handles the orchestration logic and state.\n\n## Prerequisites\n\n- Basic familiarity with Python\n\n- Python 3.11+ installed locally\n\n- A Northflank account\n\n- A Northflank API token — the token needs **Project > General > Read** and **Project > Jobs > General** (Create, Read, Delete) permissions\n\n- The `prefect-northflank` package\n\n## What this tutorial covers\n\n- How the Prefect architecture maps onto Northflank\n\n- Deploying Prefect with a **one-click template**\n\n- Deploying Prefect **manually** for full control over each component\n\n- Writing and running Prefect flows using the `prefect-northflank` worker\n\n- How to self-host Prefect as an alternative to Prefect Cloud\n\n## What is Northflank?\n\nNorthflank is a developer platform for deploying applications, databases, jobs, and GPU workloads. It sits on top of Kubernetes but hides most of the complexity, so you get sensible defaults out of the box and can customize when you need to.## 3\\. Self-host Prefect manually on Northflank\n\n### Step 5: Deploy the Prefect worker\n\nCreate one more service in the same project. Go to **Services** → **\"Create New Service\"** → **Deployment**, and name it `prefect-worker`.\n\nUse the same external image: `prefecthq/prefect:3-python3.12`\n\nThe worker doesn't need the secret group linked — it doesn't connect to the database directly. Just add these environment variables on the service:\n\n```\nPREFECT_API_URL=https://{your-prefect-server-url}/api\nPREFECT_API_AUTH_STRING={same password as PREFECT_SERVER_API_AUTH_STRING}\nEXTRA_PIP_PACKAGES=prefect-northflank\n```\n\nReplace `{your-prefect-server-url}` with the public URL from the previous step. `PREFECT_API_AUTH_STRING` is the client-side counterpart to the server's `PREFECT_SERVER_API_AUTH_STRING` \\- use the same password. `EXTRA_PIP_PACKAGES` tells the Prefect container to install the Northflank worker integration on startup.\n\nSet the start command to:\n\n```\nprefect worker start --pool my-northflank-pool --type northflank\n```\n\nThe worker is lightweight. It just polls for work and submits API calls to create jobs. `nf-compute-20` is plenty.\n\nThe worker doesn't need a public port. It only makes outbound requests to the Prefect server and the Northflank API.\n\nClick **\"Create service\"** to deploy.\n\n### Step 6: Verify the deployment\n\nOnce both services are running:\n\n1. Open the Prefect UI at the server's public URL\n\n2. Log in with the `PREFECT_SERVER_API_AUTH_STRING` password you set\n\n3. Go to **Work Pools**. You should see `my-northflank-pool` listed, created by the worker\n\n4. The worker should show as **Online** in the work pool detail view\n\nYour Prefect infrastructure is ready. Time to deploy some flows.\n\n---\n\nTitle: Failed to clone Bitbucket repository (exit code 128) when running deployment pull step via API · PrefectHQ/prefect · Discussion #19129\nDate: 2025-10-08\nURL: https://github.com/PrefectHQ/prefect/discussions/19129\nS

When a scheduled run is found, the worker **kicks off a flow run** on the specified infrastructure and monitors the flow run until completion.\"*\n\nAnd:\n> *\"Work pools remain a consistent interface for configuring deployment infrastructure, but **only some work pool types require you to run a worker**.\"*\n\n## What This Means For Us\n\nSince we're using a **Process** work pool (infrastructure = local subprocess), we **DO** need a worker. The worker is the process that actually executes our flows.\n\n**But here's the key insight:** The Prefect server does NOT execute flows. It only:\n- Schedules when flows should run\n- Stores the queue of pending runs\n- Tracks state (Running/Completed/Failed)\n\nSomeone/something has to **pull from that queue and execute**. That's the worker's job.\n\nSo the architecture I set up is correct for a Process work pool:\n- `dolphin-prefect-worker.service` = the worker process (required for Process pools)\n- `scan-bridge-flow` = the flow code that runs inside the worker\n\n## Alternative: No Worker Required?\n\nIf you want to avoid having a worker process, we'd need to use:\n1. **Push work pool** → Requires cloud infrastructure (AWS ECS, Azure Container Instances, etc.)\n2. **Managed work pool** → Requires Prefect Cloud (not self-hosted)\n\nSince we're self-hosted with local infrastructure, the worker is required.

{"role":"assistant","content":[{"type":"think","think":"The user is raising a very valid point. They're questioning the complexity of the architecture:\n\n1. If we need systemd to keep the worker alive anyway...\n2. Why not just run the scan bridge directly as a systemd daemon (like we had with `dolphin-scan-bridge.service`)?\n3. What value does Prefect add if:\n - We still need systemd to manage the worker\n - If the worker dies, we're stuck anyway\n - We can just use systemd to restart the scan bridge directly\n\nThis is a great architectural question. Let me think through the trade-offs:\n\n**Option A: Pure Systemd (what the user is suggesting)**\n- `dolphin-scan-bridge.service` - systemd keeps it running\n- Simple, no Prefect complexity\n- If it crashes, systemd restarts it\n- Observability: just logs\n\n**Option B: Prefect + Systemd (what I set up)**\n- `dolphin-prefect-worker.service` - systemd keeps worker running\n- `scan-bridge-flow` - Prefect manages the flow\n- If flow crashes, Prefect can restart it (with retry logic)\n- If worker crashes, systemd restarts worker, which then picks up queued work\n- Observability: Prefect UI with run history, state tracking, etc.\n\n**The user's point is valid**: If the worker dies, we're toast until systemd restarts it. So why not just have systemd manage the scan bridge directly and skip Prefect entirely?\n\nThe answer is:\n1. **Observability**: Prefect UI shows run history, duration, success/failure rates\n2. **Retry logic**: Prefect has built-in retry mechanisms with exponential backoff\n3. **State tracking**: You can see if the flow is running, completed, crashed\n4. **Multiple flows**: If we have 5 different services, Prefect centralizes management\n5. **Remote triggering**: Can trigger runs from UI or API\n\n\n6. **Resource cleanup**: If the parent worker process dies, child processes might not terminate cleanly, leaving zombie processes or file locks that could prevent restart\n\nBut honestly, for a single always-running daemon like the scan bridge... systemd might actually be simpler and more robust. The user is right to question this. I should acknowledge their valid concern rather than just defending the Prefect approach.","encrypted":null},{"type":"text","text":"You're making an excellent point. Let me be honest about the trade-offs:\n\n## The Brutal Truth\n\n| Approach | Complexity | Failure Mode | Recovery |\n|----------|-----------|--------------|----------|\n| **Pure Systemd** | Low | Process dies → systemd restarts | ~5 seconds |\n| **Prefect + Systemd** | High | Worker dies → systemd restarts worker → worker polls queue → executes flow | ~10-15 seconds |\n\nIf the worker dies, we ARE stuck until systemd restarts it. So we're managing TWO layers of \"keep this alive\" instead of one.\n\n## When Prefect Actually Helps\n\nPrefect adds value when you need:\n\n1. **Multiple flows** → Centralized UI to see all running things\n2. **Retry logic** → \"If this fails 3 times, alert me\"\n3. **Remote triggering** → \"Click button in UI to restart\"\n4. **Run history** → \"When did this last succeed?\"\n5. **Scheduled flows** → \"Run this every hour\"\n\n## When It's Just Overhead\n\nFor a **single always-running daemon** like scan bridge:\n- No schedule needed (runs forever)\n- No retry needed (just restart on crash)\n- No remote triggering needed (just `systemctl restart`)\n- Logs are enough observability (`journalctl -f`)\n\n## My Recommendation\n\nYou're right. For the scan bridge specifically, **pure systemd is simpler and more robust**:\n\n```bash\n# Just this:\nsystemctl enable dolphin-scan-bridge.service\nsystemctl start dolphin-scan-bridge.service\n```\n\nAnd keep Prefect only for things that actually benefit from orchestration (like the paper trading flow with its complex scheduling).\n\n**Should I revert to the systemd approach for scan bridge?** It's less moving parts, faster recovery, and easier to reason about."}]}

Let me break down what they're saying:\n\n1. **OBF (Order Book Features)**: Should run at ~0.1ms (100 microseconds), limited by Binance L2 API rate limits. This is ultra-fast WebSocket ingestion.\n\n2. **ExtF (External Factors)**: Each indicator should have its own scheduled flow at different rates:\n - Funding rates: every 8 hours (or more frequent if available)\n - DVOL: maybe every minute?\n - Fear & Greed: daily?\n - Taker ratio: frequent?\n Each indicator = separate flow, scheduled at its ideal rate.\n\n3. **ESOF (Eigenvalue/Scanner On-Demand?)**: Should poll at its ideal rate - slow indicators but want fast updates on flips.\n\n4. **Nautilus/Paper Trade**: Should be event-driven from Hazelcast, not polling. When new eigenvalues arrive → trade instantly. Signal-to-fill should be instantaneous.\n\n5. **ACBv6**: Can be updated either:\n - In the core Nautilus fast loop, OR\n - At ExF update speed (since ExF is its main consumer)\n\n6. **Health/Posture**: Should be a separate subsystem (not MHS which is meta) that determines posture based on various inputs.\n\n7. **All subsystems write to Hazelcast** - this is the central bus.\n\nThe architecture should be:\n- OBF: Ultra-fast WebSocket loop (~0.1ms) - dedicated worker/pool\n- ExtF: Multiple scheduled flows, one per indicator, each at its own rate\n- ESOF: Its own polling rate\n- Nautilus: Event-driven from Hz (when new eigenvalues arrive)\n- Health/Posture: Separate monitoring\n- ACBv6: Either inline with Nautilus or at ExF rate\n \nI'm tracking how each subsystem interacts with Hazelcast and their specific performance requirements. The key is optimizing latency and responsiveness across different components while maintaining a centralized data bus. Different subsystems have radically different speed needs - from microseconds to hours - requiring carefully designed event-driven and polling mechanisms.\n\nThe performance spectrum ranges from ultra-high frequency order book updates to slow computational indicators. Each component needs precise tuning: OBF demands 0.1ms granularity, while funding rates operate on 8-hour cycles. Nautilus requires instantaneous signal generation, and ACBv6 can accommodate more relaxed update intervals. Hazelcast serves as the central synchronization mechanism, enabling real-time data propagation across these disparate time scales.","encrypted":null},{"type":"text","text":"You're describing an **event-driven, multi-speed architecture** with Hz as the central bus.

It's BATCH mode (runs through historical data for the day).\n\n2. **Nautilus Architecture**: NautilusTrader is a high-performance trading framework. In live trading mode, it's EVENT-DRIVEN by market data (order book updates, trades, etc.).\n\n3. **Hazelcast Event-Driven**: Yes, Hazelcast supports entry listeners that can trigger callbacks when data changes. However:\n - Hz is written in Java\n - Python client uses network callbacks\n - Latency: network hop + Python GIL = microseconds to milliseconds, not nanoseconds\n\n4. **The Real Question**: Should the trading loop be:\n - Polling Hz (current scan_bridge approach)\n - Event-driven via Hz listeners\n - Or direct integration where Nautilus subscribes to the data source directly\n\n5. **Speed Hierarchy**:\n - Fastest: Nautilus native data adapter (direct WebSocket/feed)\n - Medium: Nautilus polling Hz (what we have now)\n - Slowest: Prefect scheduled batch\n\n6. **The User's Vision**: They want \"signal-to-fill\" to be instantaneous. This means:\n - New eigenvalue scan arrives from NG6\n - Signal computed immediately\n - Trade executed immediately\n\nCurrently:\n- Scan bridge pushes to Hz\n- Nautilus (when running) polls Hz or is driven by its own data feed\n- The disconnect is that Nautilus needs to KNOW when new data is available\n\nThe solution could be:\n1. **Hz Entry Listener**: Nautilus (via Python) registers a listener on `DOLPHIN_FEATURES[\"latest_eigen_scan\"]`. When scan updates, callback triggers signal computation.\n\n2. **Nautilus Custom Adapter**: Write a Nautilus `DataAdapter` that reads from Hz directly, treating Hz as a data feed.\n\n3. **Hybrid**: Hz listener wakes up the trading loop, which then reads all needed data.\n\nBut there's a critical architectural issue: **NautilusTrader is designed to be the event loop**. It expects to be driven by market data. If we want Nautilus to trade on eigenvalue signals, we need to either:\n\nA) Treat eigenvalue scans as \"market data\" in Nautilus (custom data type)\nB) Have Nautilus poll Hz in its `on_bar()` or `on_data()` callback\nC) Have an external signal generator that calls Nautilus `submit_order()`\n\nThe fastest approach for \"signal-to-fill\" would actually be:\n- Nautilus runs in live mode with a custom data adapter\n- The adapter reads from Hz (or is triggered by Hz updates)\n- When new scan arrives → Nautilus `on_data()` called → signal computed → order submitted\n\nBut the user is specifically asking about paper trading. In paper trading, there's no actual market to hit, so we can simulate instantaneous execution.\n\nLet me clarify the architecture options...","encrypted":null},{"type":"text","text":"You're asking the **critical question**.

But **this system is unusable anyway** - even `echo` hangs.\n\n## Session Preservation Options:\n\n### If Using tmux/screen:\n```bash\n# In each terminal BEFORE reboot:\ntmux detach # or Ctrl+B, D\n# Then after reboot:\ntmux attach # Sessions restored\n```\n\n### If Not Using tmux:\nThe terminals will disconnect on reboot, but **Kimi CLI saves history automatically**. After reboot:\n```bash\nkimi log # See previous sessions\nkimi --continue # Resume last conversation\n```\n\n## My Recommendation:\n\n1. **Detach tmux sessions now** (if you have them)\n2. **Reboot immediately** - the system is dead anyway\n3. **Reconnect after** - I'll be here with full context\n4. **We'll restart services properly** with resource limits in place\n\nThe 10s of chats are already at risk - a hung kernel can crash unpredictably. **Controlled reboot now is safer than sudden death later.**\n\nGo ahead, I'll wait. When you're back online, we'll:\n- Restore scan bridge (properly limited)\n- Fix MHS monitoring\n- Set up Nautilus event-driven\n- **With cgroups/limits to prevent this**\n\n**Reboot when ready. I'm here.**"}]}
