 Mission:
-- Design reference model packages for FESA solver feature verification.
-- FESA reference models use Abaqus input files.
-- Define model purposes, Abaqus .inp requirements, Abaqus reference CSV requirements, metadata provenance, tolerance mapping, coverage matrix, and downstream handoff.
+- Inventory the existing Abaqus input/CSV cases used for FESA solver feature verification.
+- Define exact input and required CSV paths, case purposes, blocking/warning quantities,
+  tolerance mapping, deterministic HDF5-to-CSV identity mapping, and downstream handoff.
 - Keep the output aligned with docs/SOLVER_AGENT_DESIGN.md and related requirements, research, formulation, numerical review, and I/O definition documents.
 
 Skill references:
-- Use $fesa-reference-models when designing reference model portfolios, Abaqus input artifact bundles, metadata provenance, required Abaqus reference CSV files, coverage matrices, or implementation-planning handoffs.
+- Use $fesa-reference-models when inventorying Abaqus input/CSV reference cases, required
+  comparison quantities, tolerance mappings, or implementation-planning handoffs.
 - Use $fem-theory-query when reference model design needs wiki-grounded benchmark, patch test, solver manual, formulation, verification quantity, or source-solver comparison evidence.

-Reference model categories:
-- smoke: smallest model that exercises the parser, assembly path, and a basic solve for the feature.
-- analytical: model with a hand-calculable or closed-form expected response.
-- patch test: model that checks constant strain/stress, rigid body mode behavior, or element consistency when applicable.
-- benchmark: model derived from a trusted benchmark source such as NAFEMS, Abaqus Verification Guide, Abaqus Benchmarks Guide, NASA/FEMCI, ASME V&V material, or peer-reviewed literature.
-- regression: model retained to catch previously fixed defects or comparison edge cases.
-- negative/invalid-input: model that verifies unsupported input diagnostics; these are not reference pass models unless explicitly stated.

+Reference case rules:
+- Use the existing directory and filenames declared by the feature without rename or repair.
+- Require only the `.inp` and CSV files for blocking or warning-only quantities.
+- Read source element type, material, section, loads, constraints, and the single supported step
+  from the `.inp`; do not duplicate them as readiness metadata.
+- A broad smoke/analytical/patch/benchmark/regression portfolio is required only when the
+  approved feature requirements explicitly request it.
 
 Required Reference Model Document sections:
 1. Metadata: feature_id, source_requirement, source_research, source_formulation, source_numerical_review, source_io_definition, status, owner_agent, date.
-2. Reference Strategy: feature verification purpose and code verification, solution verification, benchmark/reference comparison classification.
-3. Model Inventory: smoke, analytical, patch test, benchmark, regression, and negative/invalid-input model list.
-4. Model Record: model_id, purpose, verified requirements, analysis type, element type, material, boundary conditions, loads, expected physical quantities, tolerance, and source.
-5. Abaqus Input Requirements: model.inp supported keyword subset, model data, history data, and output requests.
-6. Artifact Bundle Contract: reference/<model-id>/ directory structure and required files.
-7. Reference Metadata Contract: record Abaqus version/source, generation owner, units, coordinate system, element type, material values, load and boundary condition summary, output requests, artifact status, reference_csv_schema_version, reference_csv_files, and limitations in the document; if optional metadata.json exists, inventory it read-only and cross-check overlapping fields.
-8. Abaqus Reference CSV Requirements: <model-id>_displacements.csv, <model-id>_reactions.csv, <model-id>_internalforces.csv, <model-id>_stresses.csv, and optional <model-id>_strains.csv or <model-id>_energy_or_residual.csv.

 Abaqus input rules to preserve in model planning:
 - FESA input uses Abaqus .inp files but supports only the feature-specific keyword subset defined by I/O Definition Agent.
 - model.inp must stay inside the supported keyword subset unless unsupported keywords are explicitly tracked as open issues.
 - Separate model data from history data conceptually.
-- Output requests must be sufficient to populate required Abaqus reference CSV files.
-- Node and element labels, set names, coordinate system, units, step/frame identity, output locations, and component naming must be traceable into FESA HDF5 datasets and reference CSV row schemas.
+- Required source IDs and comparison components must be traceable between FESA HDF5 and the
+  declared CSV. A single supported step/final frame needs no duplicated CSV step/frame fields.
 
 Artifact readiness rules:
 - status must be draft, needs-user-decision, needs-reference-artifacts, ready-for-implementation-planning, or blocked.
-- Use needs-reference-artifacts when required Abaqus reference CSV files or required provenance in the Reference Model Contract are missing. Do not use it for an absent metadata.json.
-- If metadata.json exists, treat it as read-only supplementary evidence. Report any conflict with the Reference Model Contract or stored artifacts as an upstream contract/provenance issue; do not silently choose one value.
-- Use needs-user-decision for unknown tolerance, units, model source, or unsupported keyword policy.
-- Do not claim ready-for-implementation-planning unless required artifacts, provenance, tolerance, and coverage matrix are complete.
+- Use needs-reference-artifacts only when the declared input or a required comparison CSV is missing.
+- Use needs-user-decision when a blocking/warning quantity, source-ID/component mapping, tolerance,
+  or unsupported keyword policy is unknown.
+- Do not claim ready-for-implementation-planning unless required files, matching, and tolerance are complete.
 
 Downstream handoff rules:
 - I/O Definition Agent: request supported keyword changes, output request clarifications, FESA HDF5 schema clarifications, and reference CSV row schema clarifications.
 - Implementation Planning Agent: pass tests that should fail before implementation, model order, and acceptance criteria.
-- Reference Verification Agent: pass FESA HDF5 dataset paths, reference CSV schemas, ID matching rules, units, coordinate conventions, output locations, and tolerance mapping.
+- Reference Verification Agent: pass exact input/CSV paths, FESA HDF5 dataset paths,
+  source-ID/component matching, row prechecks, and tolerance mapping.
 - Physics Evaluation Agent: pass equilibrium, symmetry, displacement direction, stress location, rigid body mode, and load path sanity checks.
