 The coding pilot used Terminal-Bench 2.0, a four-attempt limit, and the `claude/sonnet/low` selector. Its [method and interpretation](https://github.com/hraness/algal/blob/0c458a95ee04a01f16265dd9825c202b75b929d9/docs/coding-harness-pilot-results.md) describe the small sample, policy selection, and unavailable token and subscription-cost attribution. Receipt verification checks recorded execution integrity; task grading measures task success. The selected policy remained the original policy. This pilot demonstrated no performance benefit.

 The follow-up calibration used three fresh corpora with labeled training examples and training-only feedback. Two seeds passed validation and the third exhausted eight generations, so no confirmatory arm ran. Fixed calibration tests passed 2/8 and 3/8; one recorded transport failure had uncertain external completion and missing usage. Runtime work and charged-attempt totals are reported, while provider billing remains unavailable.
 
+The second calibration added a fourth corpus, a separate development batch whose pass indicator was the only new signal the seed writer received, and a fixed schedule of eight revision modes. Two seeds passed validation and two exhausted eight generations. All 22 scored development batches failed, so the writer's score history never varied. Both fixed seeds passed 4/8 tests. One recorded transport failure again had missing usage. The fresh draws provide no paired comparison with the previous calibration.

 ## Files and reuse
 
 The JSON files preserve the published result records byte for byte, including recorded failures, null usage values, source identities, and limitations. Their schemas differ because the studies answer different questions. Use Python's `json` module or another JSON reader to inspect a study; this archive does not define a combined training split.
