Read `docs/onboarding/START_HERE.md`\n3. Run the minimal example path\n\n## Public API\n\n- `FMT.Graph`\n- `FMT.Logic`\n- `FMT.Game`\n- `FMT.Types`\n- `FMT.Invariants`\n\n## URF routing\n\nThis repository is a finite-model-theory library and formalization surface within the broader URF program.\n\nCanonical URF definitions, theorem statements, dependency ledgers, and closure claims remain in `urf-core`.\n\nCommunity-additive examples, tests, implementations, and non-canonical extensions belong in `urf-core-community`.\n\n## External status\n\nThis repository is governed by [`docs/status/EXTERNAL_STATUS_LOCK.md`](docs/status/EXTERNAL_STATUS_LOCK.md). Build success, CI success, dashboards, ledgers, axioms, admits, `sorry`, or placeholder witnesses do not constitute theorem-level closure.\n\n\n## Lean proof portfolio classification\n\nThis repository is governed by [`docs/status/LEAN_PROOF_PORTFOLIO_CLASSIFICATION.md`](docs/status/LEAN_PROOF_PORTFOLIO_CLASSIFICATION.md). Its role in the portfolio is explicitly classified as proof-facing, conditional frontier, infrastructure/documentation, or legacy/scaffold.\n## Formal Status\n\nStatus: Clean Formal Scaffold / Needs Theorem Audit\n\nBuild status:\n- A successful build means the checked root target compiles.\n- It does not imply that the repository contains a final solve.\n\nTheorem status:\n- A `Prop` specification is not a proof.\n- A target statement is not a proof.\n- No final-solve claim is asserted at repository level.\n- A final theorem claim requires an identified file name, theorem name, dependency chain, and proof status.\n\nCurrent status:\n- Strongest verified theorem: not asserted at repository level\n- Weakest missing object: exported-theorem audit separating definitions, specifications, verified lemmas, conditional theorems, and final theorems\n- Theorem-surface audit: `docs/status/THEOREM_SURFACE_AUDIT_2026_04_27.md`\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Finaciovasquez2020%2Fcslib-fmt","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Finaciovasquez2020%2Fcslib-fmt","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Finaciovasquez2020%2Fcslib-fmt/lists"}
