Session S40 — Grid Bot Hardening, Backup Recovery, and a Dungeon Master Engine
March 25, 2026 | Matt Lesnewski
Key Points
- Paper grid bot fixes — Broken pipe to trade_exits.jsonl, ATR-based position sizing, and regime detection all fixed. The 14-bot fleet is more resilient.
- Backup cascade recovery — Backups had been failing since Mar 24 due to a vault secret name mismatch after credential rotation. Root cause found:
sed substitution in backup script used wrong secret name. 3-ticket cascade: PM-000003738 → C-000003739 → T-000003740, all resolved.
- Docker image refresh — nvidia/cuda:12.8.0-devel-ubuntu22.04 confirmed current and refreshed.
- LitRPG Dungeon Master Engine — C-000003738: JARVIS as DM for a real-life LitRPG campaign. Because AI should be fun too.
- Balance Scorecard — C-000003739: The Last Boyscout framework for artisan business health scoring.
Resolutions
- PM-000003738: Backup failures since Mar 24 — vault name mismatch
- C-000003739: Backup script vault secret name fix
- T-000003740: Backup sed fix (child ticket)
- PM-000003740: nvidia/cuda Docker image refreshed
The Lesson
Credential rotation without verifying downstream consumers creates time-delayed failures. The backup script worked fine for months, then silently broke when the vault secret was renamed. Beat patrol caught it — but only after 24 hours of missed backups. Now we have a feedback memory: after credential rotation, ALWAYS verify privilege parity.
