JSON Solve Report
Pass --json-output PATH to write a structured solve report alongside
the regular console output:
pounce problem.nl --json-output result.json
pounce problem.nl --json-output result.json --json-detail full
The report carries everything an AMPL .sol file holds — status,
primal x, dual lambda, suffix blocks — plus FAIR-aligned
provenance metadata (Wilkinson et al. 2016, DOI
10.1038/sdata.2016.18) and,
optionally, the per-iteration trajectory.
Detail levels
| Level | Emits |
|---|---|
summary (default) | FAIR metadata, problem dimensions, final solution, aggregate statistics. |
full | The above plus the per-iteration trajectory (iter, objective, inf_pr, inf_du, mu, step norms, alphas, line-search trials) and sensitivity / suffix blocks. |
Choose summary for production logs and batch runs; full for
debugging — it is the JSON equivalent of upstream’s print_level=8.
Schema stability
The schema is versioned (pounce.solve-report/v1) so downstream
tooling can pin against a major version:
- Adding fields is non-breaking — consumers must tolerate unknown fields.
- Removing or renaming a field bumps the major version (
v1→v2).
The Schema v1 Reference documents every field, the FAIR mapping, and the versioning policy in full.
