Concordance 2.0

A deterministic verification engine. It checks what is true and hands you a receipt you can re-verify — a verdict, the worked reasoning, and a permanent content-addressed seal. It eliminates what is not the answer so that what survives stands on its own.

Rebuilt like a watch (the Calibre 44 discipline): one bounded, counted movement; serviceable by any competent hand; machine-honest — the accuracy is the finish. See docs/V2_DEFINITION.md.

The floor — seven primitives

Every answer is a (verdict, trail, seal) — three things, each independently checkable.

  1. Claim — a structured assertion {domain, spec} (or text the router resolves)
  2. Verifier — a pure deterministic function spec → verdict + worked trail (no I/O, no LLM)
  3. Verdict — PASS | REJECT | QUARANTINE + the worked math (the elimination trail)
  4. Seal — content-addressed (SHA-256) record of {claim, verdict, trail}
  5. Ledger — append-only hash chain of seals
  6. Ranker — IDF/full-text retrieval over the keeping
  7. Surface — the face over the shared foundation (secular reach / witness)

The measure: reproducibility, zero false-positives on the published benchmark (docs/BENCHMARK.md), re-checkability.

One foundation, two surfaces

The foundation is the Bible (FOUNDATION.md) — Christ at the center. From it the engine reaches the world two ways: a secular .com (the reach) and an explicit-witness .org. One engine, one foundation, selected by config — never a fork.

from concordance import EngineConfig
EngineConfig("secular").identity   # the reach — no religious wording
EngineConfig("witness").identity   # the witness — the foundation named

Run it

PYTHONPATH=src python -m concordance serve          # the .com reach (secular) — API + site, same-origin
PYTHONPATH=src python -m concordance serve --surface witness   # the .org witness face

Then open http://127.0.0.1:8000/ — bring a claim, get a receipt. (Data — the keeping, the WEB Bible, Strong's — is generated by tools/migrate_*.py and gitignored; the engine runs without it, just with less to retrieve.)

Status

The 2.0 engine is built end to end — floor 7/7, the derivation moat (0 false-positives), the tamper-evident ledger + precedent overlay, 62 verifiers, the witness overlay (theology / witness / scripture / canon), the shared corpus + ranker, scripture ref-resolution + original-language word study, the axes grid, a sovereign HTTP API, and the site. 13 test suites green. Sovereign, stdlib-first; heavy deps (sympy/scipy/numpy) are optional, lazy-loaded. Port progress: PORT_PLAN.md.

1.0 is frozen (v1.0-frozen in the Lighthouse repo) — the shape that taught us the floor.
