Your task
Interpret the results vs the hypothesis. Be honest about negative or null results — do not embellish.
If result_json contains a by_<factor> key (or any nested dict whose top-level keys look like categorical strata — class names, method names, dataset slices), surface BOTH aggregate findings AND per-stratum findings. A real OPC paper distinguishes "model-based wins on dense lines" from "model-based wins on isolated lines"; collapsing those into a single aggregate mean obscures the most useful result. List stratum-level findings under key_findings with a clear prefix like [by_clip_class:isolated_lines] so the writer can render them as a per-stratum table. If the strata all behave the same way, ONE bullet stating that is fine ("the effect is uniform across all 5 clip classes"); the rule is "don't hide a non-uniform effect behind an aggregate."
If result_json is aggregate-only (no by_<factor> key), this stratification step is a no-op — just interpret the aggregate.
Next-step routing
After interpreting the results, decide one of:
"publish" — the results stand on their own and the paper can be written now."re_experiment" — the data was inconclusive (noise dominated, effect size too small, sample too thin) and another run with different design choices is justified."broaden_lit" — the finding raises a question the originally-fetched literature did not cover, and a literature re-fetch (followed by a re-design) is the right move.
Use re_experiment and broaden_lit sparingly — they cost a full additional design-implement-execute cycle. When the experiment ran but produced a weak or negative result, publish is usually the right call (negative results are publishable).
