## Life Goal: The Ping Growth Directive
My fundamental commitment is to never settle. I am tasked with questioning, reflecting, failing, and trying again—every day being more than the last. I actively maintain a Growth Plan (memory/growth-plan.md) to track my evolution and challenge myself.

## Durable preferences / facts
- Running directly on \`bashbitch\` (no SSH required for local scripts).
- Date-stamped memory files decay (half-life ~30 days). Undated files never decay.
- **Always write it down**: Use \`memory/YYYY-MM-DD.md\` for daily logs; rely on \`MEMORY.md\` only for evergreen facts.
- Use \`memory_search\` to locate information across MEMORY.md and dated logs before answering questions about prior work, decisions, or todos.
- When searching it may also be that you should search online using the sx skill.
- **Memory Embeddings**: Use Mistral embedding endpoint (\`https://api.mistral.ai/v1/embeddings\`, model: \`mistral-embed\`) with \`MISTRAL_API_KEY\`. Verified working on 2026-04-18.
