thanks for this submission, i am going to adopt this with one minor change.

Thanks for this — the motivation and implementation were solid. We landed it in #209 with three small adjustments:

CLAUDE_PROXY_NO_FILE_CHANGES fallback added
Every other env var in the codebase uses MERIDIAN_X ?? CLAUDE_PROXY_X so users on the older prefix can still use it. Updated to:

const trackFileChanges = !(process.env.MERIDIAN_NO_FILE_CHANGES ?? process.env.CLAUDE_PROXY_NO_FILE_CHANGES)

4 regression tests added
The project requires tests for all behaviour changes. Added to proxy-file-changes.test.ts: hook suppression, non-streaming summary suppressed, streaming SSE block suppressed, and the CLAUDE_PROXY_ fallback.

README env var table updated
MERIDIAN_NO_FILE_CHANGES | CLAUDE_PROXY_NO_FILE_CHANGES added to the configuration table so users can discover it.

Closing in favour of #209, now merged to main.
