It\nreplaces the reusable intent of the former general basics/contact workflow\nwithout restoring newer-major command files.\n\n## When To Use\n\n- start or audit a PFC2D/PFC3D 5.0 case;\n- create domains, walls, balls, clumps, groups, or ranges;\n- plan current-contact versus future-contact model assignment;\n- organize build, compaction, contact installation, equilibrium, and save stages;\n- classify accepted, restart-only, diagnostic-only, failed, and obsolete states;\n- detect unsupported-version syntax in a PFC5 source tree.\n\nRoute detailed gradation/void closure to `pfc-asphalt-mixture`, FISH to\n`pfc5-fish`, servo/calibration to `pfc5-servo-calibration`, and migration or recovery\nof an existing private case to `pfc5-case-handoff`.\n\n## Required Inputs\n\n- PFC2D/PFC3D 5.0, units, sign convention, and runtime route;\n- specimen/domain dimensions and boundary behavior;\n- particle/clump size and shape abstraction;\n- material/contact pair table;\n- seed, equilibrium criterion, save/output contract.\n\n## Workflow\n\n1. Freeze version, dimension, units, axes, seed, and object abstractions.\n2. Create a clean model and domain before domain-sensitive objects.\n3. Define future-contact defaults with PFC5 top-level `cmat`.\n4. Create boundaries, particles/clumps, groups, and reusable ranges.\n5. Form contacts, then audit counts/types before changing existing contacts.\n6. Compact or equilibrate to an explicit criterion.\n7. Install final contacts transactionally: save, apply, cycle, audit, solve, save.\n8. Initialize measurements before loading.\n9. Run `scripts/audit_pfc5_case.py` and an actual PFC5 syntax probe.\n\nFor an existing project, restore and audit the last claimed accepted state before a\nfull rebuild. A restart-only state may seed a recovery branch only when its object and\ngeometry invariants are known; re-run the original final gates without weakening them.\n\nRead [stage-gates.md](references/stage-gates.md) for lifecycle checks and\n[pfc5-command-boundary.md](references/pfc5-command-boundary.md) when auditing\nsyntax.\n\n## Non-Negotiable Rules\n\n- Do not infer PFC5 compatibility from an extension or old filename.\n- Separate future defaults from existing-contact reassignment.\n- Do not delete all contacts as a generic model-switch recipe.\n- A fixed cycle count does not prove equilibrium.\n- Source audit is static evidence only; runtime acceptance remains required.\n\n## Output Contract\n\nReturn the PFC5 stage map, object/group/range map, contact assignment table,\nequilibrium criteria, save map, audit report, and `runtime_validated` status.\n\n## Local Contents\n\n- `references/stage-gates.md` — build-to-delivery gates.\n- `references/pfc5-command-boundary.md` — syntax-family boundary.\n- `scripts/audit_pfc5_case.py` — deterministic source-tree audit.\n- `agents/openai.yaml` — interface metadata.\n","tagline":"Build and audit PFC2D/PFC3D 5.0 model foundations for asphalt cases, including lifecycle, domain, balls, walls, clumps, groups, ranges, top-level cmat, staged saves, and source-version purity.","category":"security","tags":["agent-skill"],"author":"Echo-aloha","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"recursive skill source sync","sourceDetail":"Echo-aloha/asphalt-codex-skills-5","creatorName":"Echo-aloha","creatorUrl":"https://github.com/Echo-aloha","sourceUrl":"https://github.com/Echo-aloha/asphalt-codex-skills-5/tree/main/skills/pfc5-core-modeling","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/echo-aloha-pfc5-core-modeling#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
