Complete procedures with a way back.

Create one concise canonical project policy, accurate adapters and path scopes for Codex, Claude Code, Gemini CLI and GitHub Copilot, then secure, test, version and roll back the resolved bundle.

Engineer a production prompt as a versioned, evidence-grounded application contract with explicit instruction hierarchy, safe abstention, representative evals, deterministic gates, controlled rollout, observability, and atomic rollback.

Build minimal, privacy-reviewed few-shot demonstrations for classification, extraction, and constrained generation; prove their value against zero-shot baselines, sealed holdouts, slices, ablations, permutations, counterfactuals, adversarial tests, and reversible rollout.
