  "markdown": "# Concordance 2.0\n\nA deterministic verification engine. It checks what is true and hands you a **receipt you can\nre-verify** — a verdict, the worked reasoning, and a permanent content-addressed seal. It\neliminates what is not the answer so that what survives stands on its own.\n\n> Rebuilt like a watch (the Calibre 44 discipline): one bounded, counted movement; serviceable by\n> any competent hand; machine-honest — the accuracy *is* the finish. See\n> [`docs/V2_DEFINITION.md`](docs/V2_DEFINITION.md).\n\n## The floor — seven primitives\n\nEvery answer is a `(verdict, trail, seal)` — three things, each independently checkable.\n\n1. **Claim** — a structured assertion `{domain, spec}` (or text the router resolves)\n2. **Verifier** — a pure deterministic function `spec → verdict + worked trail` (no I/O, no LLM)\n3. **Verdict** — `PASS | REJECT | QUARANTINE` + the worked math (the elimination trail)\n4. **Seal** — content-addressed (SHA-256) record of `{claim, verdict, trail}`\n5. **Ledger** — append-only hash chain of seals\n6. **Ranker** — IDF/full-text retrieval over the keeping\n7. **Surface** — the face over the shared foundation (`secular` reach / `witness`)\n\nThe measure: **reproducibility, zero false-positives on the published benchmark (docs/BENCHMARK.md), re-checkability.**\n\n## One foundation, two surfaces\n\nThe foundation is the Bible ([`FOUNDATION.md`](FOUNDATION.md)) — Christ at the center. From it the\nengine reaches the world two ways: a secular `.com` (the reach) and an explicit-witness `.org`.\nOne engine, one foundation, selected by config — never a fork.\n\n```python\nfrom concordance import EngineConfig\nEngineConfig(\"secular\").identity   # the reach — no religious wording\nEngineConfig(\"witness\").identity   # the witness — the foundation named\n```\n\n## Run it\n\n```bash\nPYTHONPATH=src python -m concordance serve          # the .com reach (secular) — API + site, same-origin\nPYTHONPATH=src python -m concordance serve --surface witness   # the .org witness face\n```\nThen open `http://127.0.0.1:8000/` — bring a claim, get a receipt. (Data — the keeping, the WEB\nBible, Strong's — is generated by `tools/migrate_*.py` and gitignored; the engine runs without it,\njust with less to retrieve.)\n\n## Status\n\nThe 2.0 engine is built end to end — floor 7/7, the derivation moat (0 false-positives), the\ntamper-evident ledger + precedent overlay, 62 verifiers, the witness overlay (theology / witness /\nscripture / canon), the shared corpus + ranker, scripture ref-resolution + original-language word\nstudy, the axes grid, a sovereign HTTP API, and the site. 13 test suites green. Sovereign,\nstdlib-first; heavy deps (`sympy`/`scipy`/`numpy`) are optional, lazy-loaded. Port progress:\n[`PORT_PLAN.md`](PORT_PLAN.md).\n\n1.0 is frozen (`v1.0-frozen` in the Lighthouse repo) — the shape that taught us the floor.\n",
