Architecture Decision Records
This directory contains the Architecture Decision Records (ADRs) for the CORE project.
ADRs record significant architectural decisions: what was decided, why, what alternatives were considered, and what consequences follow. They are permanent records — superseded ADRs are archived, not deleted.

Current frontier
The ADR-0091..0102 slate is fully accepted and mechanically evidenced:
- Domain Pack Contract v1 — ADR-0091
- Reviewer Registry v1 — ADR-0092
- Domain Contract v1 enforcement — ADR-0093
- Proposal Source Provenance — ADR-0094
- Miner-Sourced Teaching Proposals — ADR-0095
- Fabrication-control negative eval lane — ADR-0096
mathematics_logicreasoning-capable ratification — ADR-0097- Demo Composition Contract — ADR-0098
- Public Showcase Demo — ADR-0099
physicsreasoning-capable ratification — ADR-0100systems_softwarereasoning-capable ratification — ADR-0101hebrew_greek_textual_reasoningmulti-pack reasoning-capable ratification — ADR-0102
Six lanes are SHA-pinned in scripts/verify_lane_shas.py and gated by the lane-shas GitHub Actions workflow: reviewer_registry, domain_contract_validation, miner_loop_closure, fabrication_control_summary, demo_composition, public_demo.
The next implementation frontier is open. Candidate directions include:
- Curriculum-sourced proposals. ADR-0094 reserved
ProposalSource(kind="curriculum"); a curriculum ADR can introduce it without secondary schema churn. - Holdout splits for language-specific lanes. ADR-0102 currently relies on universal lanes (
inference_closure,fabrication_control); language-specific fluency lanes (evals/hebrew_fluency/,evals/koine_greek_fluency/) need sealed holdout splits before they can attach toreasoning-capableclaims. - Expert-demo ratification. All ADR-0097/0100/0101/0102 ledger rows currently sit at
reasoning-capablewithexpert_demo=false. The next status tier requires evidence beyond the universal lanes.
No ADR currently sits in a "Proposed but unimplemented" state.
Accepted reasoning-capable domains
| Domain | Ratification ADR | Pack(s) | Evidence summary |
|---|---|---|---|
mathematics_logic |
ADR-0097 | en_mathematics_logic_v1 |
All nine ADR-0091 predicates pass; ledger row is reasoning-capable; expert_demo remains false; lanes include positive coverage, inference closure, and fabrication control. |
physics |
ADR-0100 | en_physics_v1 |
All nine predicates pass; causal/modal operator coverage meets threshold; ledger row is reasoning-capable; expert_demo remains false. |
systems_software |
ADR-0101 | en_systems_software_v1 |
All nine predicates pass; transitive/causal operator coverage meets threshold; ledger row is reasoning-capable; symbolic_logic is the v1 closest-fit eval lane. |
hebrew_greek_textual_reasoning |
ADR-0102 | grc_logos_micro_v1, grc_logos_cognition_v1, he_logos_micro_v1, he_core_cognition_v1 |
First multi-pack ratification; all four packs carry uniform contract fields; causal/contradiction operator coverage meets threshold; universal lanes are declared until language-specific holdouts land. |
ADR chain notes
Forward Semantic Control closure — ADR-0022 through ADR-0026
ADR-0022 through ADR-0026 form a single coherent chain that closes forward semantic control as a non-stochastic, replay-deterministic, trace-evidenced mechanism.
- ADR-0022 establishes
AdmissibilityRegionand the contract that a region restricts the admissible token set at generation time. - ADR-0023 records proof evidence that the admissibility region is honored at the region-intersection level.
- ADR-0024 adds destination-side per-step admissibility and honest
InnerLoopExhaustionwhen all admissible candidates are rejected. - ADR-0025 adds rotor/frame admissibility when a region carries a
frame_versor. - ADR-0026 replaces static threshold tuning with ranked admissibility and a scale-invariant margin gate.
Runtime contracts for the chain are pinned in docs/runtime_contracts.md.
Pack-layer chain — ADR-0027 through ADR-0045
ADR-0027 through ADR-0045 establish the identity / safety / ethics pack architecture with deterministic remediation, audit completeness, telemetry, operator readout, audit-tour demo, pack measurements, a worked-example medical ethics pack, and long-context comparison measurements.
Evidence-governed domain chain — ADR-0091 through ADR-0102
ADR-0091 through ADR-0102 establish the current domain-ratification substrate:
contract definition
↓
reviewer trust root
↓
validator / ledger enforcement
↓
negative-control fabrication lane
↓
reasoning-capable domain ratification
No domain claim should be treated as mature merely because a pack exists. Capability status belongs to the generated ledger and its evidence predicates.
