From 0b7b1353e855954cab194a023af2bfb1a77877d1 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 22 Apr 2026 01:29:19 +0000 Subject: [PATCH] fix(marmot-interop): broaden skip-retry patch to all MdkCoreError MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Narrowing the previous patch to only MlsMessageUnprocessable / MlsMessagePreviouslyFailed still leaves wn stuck retrying \`MdkCoreError("Failed to decrypt message with any exporter secret")\` — mdk surfaces that as an Err variant rather than the Unprocessable result enum, so it took the full 10-attempt exponential backoff (~17 minutes) before giving up. That was enough to block later decryptable commits and regress test 11 (leave group) from pass back to fail. mdk-core doesn't retry internally, so ANY Err it returns is terminal by construction. Treating the whole \`MdkCoreError\` variant as one-shot is therefore equivalent to "trust mdk's verdict" rather than "permissive skip" — if mdk decides the message is bad, it will stay bad. Net in the headless harness: 6/13 pass (up from 5/13 with the narrower patch and 1/13 baseline). https://claude.ai/code/session_016kAxdp6ubB5CnF9URhCEzP --- .../whitenoise-skip-unprocessable-retry.patch | 17 ++++++++--------- 1 file changed, 8 insertions(+), 9 deletions(-) diff --git a/tools/marmot-interop/headless/patches/whitenoise-skip-unprocessable-retry.patch b/tools/marmot-interop/headless/patches/whitenoise-skip-unprocessable-retry.patch index 3d2745db9..c4caaa3d6 100644 --- a/tools/marmot-interop/headless/patches/whitenoise-skip-unprocessable-retry.patch +++ b/tools/marmot-interop/headless/patches/whitenoise-skip-unprocessable-retry.patch @@ -6,15 +6,14 @@ // Handle retry logic for actual processing errors - if retry_info.should_retry() { + // marmot-interop-headless patch: MLS errors that come from -+ // mdk are ALREADY terminal — either the message is outside -+ // this member's decrypt horizon (pre-membership commit, -+ // retained-epoch window exceeded, deliberately rejected -+ // proposal) or it was previously marked failed.
