Use when creating, migrating, updating, or superseding a genrt architecture decision. Do not use for local implementation notes or backlog items that do not change durable ownership, ABI, lifecycle, or determinism policy.
Use for nontrivial genrt features, refactors, and hardening that require discovery, implementation, independent verification, and documentation sync. Do not use for typos or isolated local documentation edits.
Use when behavior or documentation changes require README, project-memory, command, and link synchronization. Do not use to duplicate deep subsystem details into the root README.
Use when adding, changing, debugging, or reviewing genrt AArch64 QEMU contract tests and test artifacts. Do not use for ordinary interactive QEMU demos without machine assertions.
Use for reviewing a genrt patch, branch, PR, or uncommitted diff for current defects and test gaps. Do not use as a broad redesign or backlog-generation exercise.
Use before completing a genrt implementation or review to select and run evidence-based checks. Do not claim checks that were not executed or substitute this matrix for task-specific acceptance tests.
