BS Cost Theory Opt

Use this skill when the task is to move from heuristic cost terms to a validated optimization model that can be promoted only after passing gates.

Background Knowledge Links

This skill must stay grounded in:

1. KB workflow and policy context, especially:

• docs/knowledge_base/80_BSCOST_THREE_SKILL_WORKFLOW_20260304.md
• docs/knowledge_base/84_REPLACE_COMPARISON_POLICY_20260304.md
• relevant backside judgment KB notes when applicable.

2. Paper-derived evidence already summarized into local notes or paper-summary artifacts.
3. Experiment-experience artifacts from eda-experiment-phenomenology-analyst when related local runs already exposed reusable results, conclusions, or repeated failure patterns.
4. Scoped retrieval from eda-context-accessor when the task needs refreshed KB or paper context before fitting or promotion judgment.

If current empirical evidence contradicts the linked background knowledge:

• keep the contradiction explicit,
• block promotion if the theory basis is no longer defensible,
• request KB update or overturn follow-up when needed.

Mandatory artifacts

1. *.dataset.tsv (dataset-level scorecard)
2. *.per_fold.tsv (fold-level evidence)
3. *.summary.md with final PASS/FAIL and open risks
4. include gate mode flag: region_exact vs proxy_mode

Operational References

1. Load references/background-knowledge-links.md when identifying which KB docs, paper summaries, and theory assumptions are authoritative for the current modeling task.
2. Load references/theory_formulation.md when locking metric contract, sign convention, and physically meaningful feature blocks.
3. Load references/optimization_and_gates.md when running repeated validation, HPWL comparison, and promotion gating.
4. Load references/internet_benchmark_notes.md when extending beyond current datasets and benchmark provenance must be refreshed from primary sources.
