ADR-0102 — Hebrew-Greek Textual-Reasoning Reasoning-Capable Ratification

Status: Accepted Date: 2026-05-21 Accepted: 2026-05-22 Author: CORE agents + reviewers Depends on: ADR-0091, ADR-0092, ADR-0093, ADR-0096, ADR-0097

Acceptance evidence

Accepted after hebrew_greek_textual_reasoning became a mechanically ratified multi-pack reasoning-capable ledger row:

grc_logos_micro_v1, grc_logos_cognition_v1, he_logos_micro_v1, and he_core_cognition_v1 carry uniform Domain Pack Contract v1 fields.
teaching/domain_chains/hebrew_greek_textual_reasoning_chains_v1.jsonl supplies reviewed active chains.
tests/test_adr_0100_0102_sibling_ratifications.py pins:
- all nine predicates pass for each of the four packs
- the ledger row status is reasoning-capable
- provenance points at adr-0102:reviewed:*
- expert_demo remains false
- claimed operators causal and contradiction meet chain coverage
- declared lanes include inference_closure and fabrication_control
- all four contracts are identical modulo pack identity

Context

The hebrew_greek_textual_reasoning substrate is structurally complete across four packs:

grc_logos_micro_v1, grc_logos_cognition_v1, he_logos_micro_v1, he_core_cognition_v1.
teaching/domain_chains/hebrew_greek_textual_reasoning_chains_v1.jsonl.
docs/gaps.md marks relevant Hebrew/Greek textual-reasoning gaps closed.
Chain coverage and intent-shape coverage satisfy ADR-0091 predicates.

Unlike mathematics_logic, physics, and systems_software, this is a multi-pack domain. ADR-0091 predicates evaluate per pack; the ledger row aggregates. Each of the four packs must carry the same domain contract so per-pack validation passes uniformly.

Decision

Ratify all four Hebrew/Greek packs as reasoning-capable under ADR-0091 by emitting the contract fields into each manifest. Each pack declares the same domain_id, teaching_chains, eval_lanes, and reviewers, with a uniform provenance trail for this ratification.

Manifest additions (all four packs)

{
  "domain_contract_version": 1,
  "domain_id": "hebrew_greek_textual_reasoning",
  "axioms": null,
  "rules": null,
  "teaching_chains": ["hebrew_greek_textual_reasoning_chains_v1"],
  "eval_lanes": [
    {"lane": "inference_closure", "version": "v1", "splits": ["dev", "public", "holdout"]},
    {"lane": "fabrication_control", "version": "v1", "splits": ["dev", "public", "holdout"]}
  ],
  "reviewers": ["shay-j"],
  "known_gaps": [],
  "provenance": "adr-0102:reviewed:2026-05-21"
}

Claimed operator families: causal, contradiction. axioms and rules stay null at v1.

Eval lane scope

Only universal lanes (inference_closure, fabrication_control) are declared. The language-specific fluency lanes currently ship dev/public only; without sealed holdout splits they are not part of this reasoning-capable ratification. A future ADR may add holdouts and attach those lanes.

Invariant

hebrew_greek_reasoning_capable_ledger_row — core capability ledger emits a row for domain_id: hebrew_greek_textual_reasoning with status: reasoning-capable, provenance pointing at this ADR, and expert_demo: False until a future ADR attaches audit-tour-equivalent reports.

hebrew_greek_pack_contracts_uniform — all four packs declare identical contract fields so multi-pack ratification cannot drift between packs without an explicit ADR.

Lane

Existing lanes carry the evidence:

inference_closure/ — composition
fabrication_control/ — negative control
evals/domain_contract_validation/ — predicate validation on each pack

Consequences

First multi-pack reasoning-capable domain ratification.
Demonstrates the contract works for both single-pack and multi-pack domains.
Future language-specific eval lanes can be added once they ship holdout splits.
