Solution Package Builder

Purpose

Create the writer's single source package and immutable numerical snapshot. Do not manufacture missing judgments or freeze unapproved claims.

Preconditions

• rigor_profile is submission.
• Final method explanation, final result analysis, robustness report, and figure plan exist.
• Human method, result, stability, and claim-scope decisions exist in qx_decisions.jsonl.
• Canonical sources are current.

Workflow

1. Collect final method structure, result claims, limitations, figures, tables, and decision provenance.
2. Draft results/Qx/reports/qx_solution_package_for_writer.md.
3. Flag every proposed top-line claim with:
   • value and unit;
   • canonical source path and location;
   • robustness support;
   • decision ID for claim scope or rationale;
   • confidence/limitation.
4. Invoke one final choice card when package sign-off is missing:
   • keep;
   • downgrade;
   • drop.
5. Route the human answer to modeler-decision-logger as package_signoff.
6. Only after sign-off, generate results/Qx/reports/frozen_numbers.json.
7. Verify every numerical package claim resolves to the freeze and every judgment claim resolves to a human decision ID.

Frozen Number Contract

Each entry contains:

{
  "claim_id": "q1_main_rmse",
  "value": 2.4,
  "unit": "units",
  "source_file": "results/Q1/experiments/final/metrics/main.json",
  "source_locator": "$.rmse",
  "frozen_at": "ISO-8601",
  "frozen_by_skill": "solution-package-builder",
  "decision_id": "q1_package_signoff"
}

Use a source line only for stable text files; use a JSON path, table key, or row/column identifier for structured data.

Rules

• Do not create solution-package-builder_modeler_decision.md.
• Do not emit frozen_numbers.json before human package sign-off.
• Never edit an existing freeze by hand.
• Transcribe human rationales; do not re-compose them as stronger claims.
• The package may cite the compact method-card history but must not depend on a separate iteration log.
• Do not copy raw exploratory outputs into the package without final validation.

Change and Re-freeze

When a canonical source changes after freeze:

1. append the reason to freeze_change_log.md;
2. update and rerun the canonical source;
3. obtain renewed human judgment when the evidence changed materially;
4. regenerate the freeze;
5. run scoped consistency for Qx.

Verification

• All prerequisites are final and current.
• Package sign-off exists in the JSONL ledger.
• Every frozen value has a real canonical source and stable locator.
• Every package number matches the freeze.
• Every modeling judgment traces to a human decision.
• Writer can use the package without searching scattered results.
