feat(adr): ADR-0107 mathematics_logic expert-demo promotion deferred (#114) 
The ADR-0106 contract correctly refused promotion. ADR-0107 records the
deferral and reserves two follow-up ADRs:

- ADR-0109 (lane-shape-aware threshold amendment): ADR-0106 \xc2\xa71.2
  prescribes cognition-pack-shape metrics uniformly, but math /
  physics / systems / hebrew-greek lanes carry native shapes
  (accuracy, passed_rate, all_pass_rate). Prerequisite for any future
  expert-demo promotion.
- ADR-0110 (math re-attempt): conditional on ADR-0109 landing and
  inference_closure substantively passing (currently all_pass_rate=0.4
  on public).

tests/test_adr_0107_deferral.py pins adr_0107_no_silent_promotion: math
stays at reasoning-capable, has no expert_demo_claims entry, and the
ledger row carries a named refusal reason.

No change to core/capability/expert_demo.py or reporting.py -- the
contract is honored, not amended. README sequencing updated to reflect
ADR-0107 acceptance and the new ADR-0109/0110 prerequisites.

# 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 They are permanent records — superseded ADRs are archived, not deleted.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..0105 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_logic` reasoning-capable ratification — ADR-0097
- Demo Composition Contract — ADR-0098
- Public Showcase Demo — ADR-0099
- `physics` reasoning-capable ratification — ADR-0100
- `systems_software` reasoning-capable ratification — ADR-0101
- `hebrew_greek_textual_reasoning` multi-pack reasoning-capable ratification — ADR-0102
- Hebrew/Greek fluency lane attachment for ADR-0102 — ADR-0103
- Curriculum-Sourced Teaching Proposals — ADR-0104
- Sealed Holdout Encryption via age — ADR-0105
Seven 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`
- `curriculum_loop_closure`
- `fabrication_control_summary`
- `demo_composition`
- `public_demo`
### Proposed-but-unimplemented ADRs
Sequencing per ADR-0108. Listed in priority order:
1. **ADR-0109 (reserved) — ADR-0106 lane-shape-aware threshold amendment.** ADR-0107 surfaced that ADR-0106 §1.2 prescribes cognition-pack-shape metrics uniformly, but math/physics/systems/hebrew-greek lanes carry their own native shapes (`accuracy`, `passed_rate`, `all_pass_rate`). Prerequisite to any future expert-demo promotion.
2. **ADR-0110 (reserved) — `mathematics_logic` expert-demo re-attempt.** Conditional on ADR-0109 landing AND `inference_closure` substantively passing (currently `all_pass_rate=0.4` on public).
3. **[ADR-0080](ADR-0080-contemplation-loop.md) — Contemplation Loop.** Sandboxed, read-only Phase 1 self-interrogation; emits `SPECULATIVE` findings from `frontier_compare` reports. Converts gap-finding from human-driven to system-emitted-and-reviewed.
4. **[ADR-0084](ADR-0084-definitional-layer.md) — Definitional Layer for Lexicon Packs.** Optional per-entry definitional block. Deferred — value surfaces during a worked expert promotion that needs definitional depth.
5. **[ADR-0087](ADR-0087-rhetorical-style-axis.md) — Rhetorical Style Axis.** A third substantive selection axis sibling to anchor-lens. Lowest current priority — no active downstream consumer; register + anchor-lens already demonstrate the orthogonality pattern.
### Open candidate directions (no ADR yet)
- **Multi-reviewer holdout governance and threshold signing.** ADR-0105 seals holdout payloads with a single recipient identity; multi-reviewer governance remains future work.

## Accepted reasoning-capable domains
Per ADR-0106, `expert_demo` is **contract-gated**, not threshold-only: a domain row may carry `expert_demo=true` only when a reviewer-signed `expert_demo_claims` entry exists whose evidence-bundle digest reproduces byte-for-byte. ADR-0107 attempted the first worked promotion (`mathematics_logic`) and the contract refused — recording two evidence-side blockers now reserved for follow-up as ADR-0109 (lane-shape amendment) and ADR-0110 (re-attempt). All four ratified domains sit at `expert_demo=false`.
| 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 + ADR-0103 | `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; ADR-0103 attaches Hebrew and Koine Greek fluency lanes with `dev/public/holdout` coverage. |

## 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.
1. **ADR-0022** establishes `AdmissibilityRegion` and the contract that a region restricts the admissible token set at generation time.
2. **ADR-0023** records proof evidence that the admissibility region is honored at the region-intersection level.
3. **ADR-0024** adds destination-side per-step admissibility and honest `InnerLoopExhaustion` when all admissible candidates are rejected.
4. **ADR-0025** adds rotor/frame admissibility when a region carries a `frame_versor`.
5. **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`](../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-0103
ADR-0091 through ADR-0103 establish the current domain-ratification substrate:
```text
contract definition
↓
reviewer trust root
↓
validator / ledger enforcement
↓
negative-control fabrication lane
↓
reasoning-capable domain ratification
↓
language-specific fluency lane attachment
```
No domain claim should be treated as mature merely because a pack exists. Capability status belongs to the generated ledger and its evidence predicates.
