Schema Normalization and Fingerprinting

Series draft — Part 10 of 15 in Hardened Agentic Stack. Outline only; expand before un-drafting.

Phase 3: Telemetry & Observability

The Problem

Noisy unique logs hide injection and abuse signals from automated systems.

The Infrastructure Fix

Standardize schemas in Alloy/OTel; strip volatile tokens so similar errors fingerprint together.

The Architecture Pattern

Data Normalization for Machine Consumption.

Planned sections

1. The “Oh No” moment — concrete incident or near-miss that makes the risk visceral.
2. ClawQL context — how this control protects a high-privilege local/edge agent.
3. Technical how-to — concrete configs, policies, or snippets a builder can apply.
4. Safety check — what “trusted enough” looks like once this layer is in place.
