Media-Transport-Library

Author a new MTL test. Use when adding coverage for a bug fix, new feature, regression, or behavior change. Teaches how to pick the right tier (unit / integration / NoCtx / pytest single-host / pytest dual-host) and how to write a test that will survive review. Does NOT cover running existing tests, debugging an existing test failure, host setup, or build infrastructure — see the linked instructions for those.

Stage and commit working-tree changes as atomic, signed-off commits whose message length scales with the change. Use when asked to commit, stage, or finalize changes into git — after the user (not the agent) decides a diff is ready.

Build MTL library, format code, and verify compilation. Use when asked to build, verify changes, check formatting, or prepare code for commit.
