system-mapping

To map system context before modifying unfamiliar code, run a 5-point pre-flight protocol covering architecture, execution flow, logging, dependencies, and environment variables. This produces a concise readiness summary of what you will affect and what to observe during verification.

The best way to trace execution flow and dependencies for a multi-file code change is to apply a pre-flight checklist that uses index-enhanced or structural search methods. This identifies entry points, call chains, imports, and configuration signals to prevent change blindness.

You need a full system context analysis for multi-file, unfamiliar-area, external-integration, and data-flow changes. A partial mapping or skip is sufficient for single-file fixes where the runtime context is already known, guided by decision-tree rules based on change size and familiarity.

Yes, you can use structural search to inventory logging and scan environment variables before editing. When structured index data is unavailable, the system mapping protocol falls back to code-search approaches to find configuration signals and trace logging statements.

Understanding architecture and runtime configuration prevents change blindness by ensuring you know the execution flow, dependency relationships, and environment variables before modifying code. This pre-flight mapping reveals hidden impacts and observability gaps before you commit changes.

Yes, system mapping works for single-file fixes with known context by applying a lightweight partial mapping. The protocol scales from focused checks for simple edits to full architectural, dependency, and execution flow tracing for complex modifications.
