Extract the CI Matrix Before a Model Reviews Your OSS Patch

说明与用途

提取 CI 矩阵并重放最旧的单元格，使模型能够在真实运行时环境下审查补丁，避免与旧工具链不匹配的问题。

问题

A contributor’s local test passes but the PR fails on older CI matrix cells because the model review ignores the repository’s actual runtime matrix.

结果

By pinning the CI matrix and replaying the oldest failing cell locally, contributors avoid model reviews that overlook runtime mismatches, leading to smoother PR merges.

工作流

• Clone the upstream repo with a named remote and create a topic branch
• Copy the workflow file and extract the matrix using a helper script
• Create ASSUMPTION_LEDGER.md with workflow, matrix, install commands, and first cell to replay
• Write a replay script that runs a single matrix cell locally
• Run the replay script to confirm the patch passes the oldest matrix cell
• Provide the ledger and replay evidence to the model for review

证据

The model never lied about the diff. It simply never saw the runtime the project actually ships.

Create ASSUMPTION_LEDGER.md with four blocks before any model sees the diff
