You are helping me build the following AI agent workflow.

## Goal
Game Player Segmentation and Churn Prediction: Ingests gameplay logs to segment players by behavior, predict churn risk, and simulate pricing adjustments for retention.

## Specification
- What it does: You automatically segment players by analyzing their gameplay logs to predict who is at risk of churning. This workflow simulates pricing adjustments so you can test retention strategies without manual data processing.
- Trigger: Triggered by an event (Event · on gameplay log webhook)
- Autonomy: Fully hands-off
- Expected setup effort: a few focused days
- Tools/services involved:
  - OpenAI Chat Model: LLM inference for agent reasoning
  - Embeddings OpenAI: Creating player behavior vectors
  - Simple Vector Store: Storing and retrieving behavioral embeddings
  - Calculator: Statistical analysis of metrics

## Known pitfalls, handle each one explicitly in your implementation
1. Vector store retrieval latency can slow down real-time responses so you should cache frequent player embeddings or use approximate nearest neighbor search.
2. Webhook payloads may contain malformed JSON from client-side errors so add a validation layer before passing data to the embedding pipeline.
3. Embedding drift over time can reduce segmentation accuracy so schedule periodic re-indexing of player behavioral vectors into the vector store.

## Reference implementation
https://n8n.io/workflows/14414 (workflow template)
Fetch and inspect this before building. If it matches my stack, adapt it;
if not, rebuild the pattern with my tools.

## Process requirements
1. Before building: ask me which of the listed tools I actually use and
   what my platform is (n8n / Make / code / other). Do not assume.
2. Adapt the pattern to my answers; do not force the reference stack.
3. Address every pitfall above; tell me how you handled each.
4. Provide a test plan I can run before letting this touch real data.
5. Ask before any step that sends messages, modifies data, or spends money.
