Documentation

README

Excerpt

Step 1 -- Reproduce

State the failure in one line: what was expected vs. what happened. Confirm reproducible before proceeding. If intermittent, note conditions.

Step 2 -- Check recent changes

Call ijfw_memory_recall with the symptom. Scan .ijfw/memory/ for decisions or changes from the past 7 days that touch the affected area.

If a recent change correlates with the regression, offer revert first:

Regression likely from <change> on <date>. Revert first? (y/n)

Step 3 -- Isolate

Narrow to the smallest reproducing case (file, function, line range).
Determine if failure is input-dependent, environment-dependent, or logic-dependent.
Read only the specific lines relevant to the hypothesis. No full-file reads.

This is the opening of the README. Read the full README on GitHub.
