regression 5

Behavior-drift reports for DeepSeek Harness agents: compare two session logs and see exactly how behavior changed — tool sequence, file operations, reasoning volume, timing, retries — no third-party dependencies, CI-ready.

DSH 试金石：给「自改造」补上评测这一环——用一套金标准用例，把改动前 vs 改动后跑一遍、打分、对比，好就留、不好就撤。

Measure whether a dsh setup change actually helped: register repeatable cases, run them, and diff the results before and after you change rules, skills, or models.

Retrospective agent-session evaluation for DeepSeek Harness: deterministic grade cards from persisted session logs, cross-session regression diffs, era comparison — no benchmark runs, no LLM judges.
