Shay bd7005c786 feat: ADR-0112 runnable expert-demo showcase (core demo expert --domain <id>) 
Closes the asymmetry between the `expert-demo` ledger status (audit
artifact only) and the actual `core demo` surface (runnable
walkthroughs producing HTML + JSON). Until this commit the word
"demo" in `expert-demo` was aspirational; now it corresponds to
something a reader can open.

What it does

- Reads the signed expert_demo_claims entry from docs/reviewers.yaml
- Loads latest on-disk result files for each attached lane × split
- Re-derives the evidence-bundle digest and asserts byte-for-byte
  match against the signed claim_digest — this is the load-bearing
  audit step, now exercised at two independent enforcement points
  (ledger gate + showcase)
- Runs each lane's metrics through the ADR-0109 lane-shape registry
  and surfaces the verdict
- Picks the first three cases from each split verbatim (deterministic
  by file order) and renders them as HTML for inspection
- Emits expert_demo.json (canonical bytes, deterministic) + expert_demo.html

Surface

  core demo expert --domain mathematics_logic
  core demo expert --domain physics
  # → evals/expert_demos/<domain>/latest/expert_demo.{json,html}

Read-only by construction: cannot mutate docs/reviewers.yaml or any
lane result file. Tested. Unpromoted domains raise ValueError —
no silent fallback, no "preview" mode that fakes a showcase.

Generated artifacts are gitignored — the inputs they derive from are
already committed, so duplicating the renders would just churn the
tree.

Tests: 16 new cases pinning all five ADR-0112 invariants. Smoke suite
still 67/67 green.

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 They are permanent records — superseded ADRs are archived, not deleted.

- `physics` Expert-Demo Promotion (second successful) — ADR-0111
- Runnable Expert-Demo Showcase (`core demo expert --domain <id>`) — ADR-0112
ADR-0080 has also landed: Contemplation Loop Phase 1 adds a read-only frontier-compare miner that emits `SPECULATIVE` findings only.
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-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.
2. **[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.
ADR-0080 (Contemplation Loop, Phase 1), ADR-0110 (math expert-demo), and ADR-0111 (physics expert-demo) have all landed — `mathematics_logic` and `physics` are at `expert_demo=true`; the contemplation loop emits read-only `SPECULATIVE` findings from `frontier_compare` reports. The remaining two ratified domains (`systems_software`, `hebrew_greek_textual_reasoning`) need their own promotion ADRs.
### 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 and the contract refused; ADR-0109 amended the threshold rules; ADR-0110 then successfully promoted `mathematics_logic` (the first domain at `expert_demo=true`); ADR-0111 promoted `physics` second without further contract change, retiring the "math-only" objection. The other two ratified domains remain at `reasoning-capable` pending their own promotion ADRs.
| Domain | Ratification ADR | Pack(s) | Evidence summary |
|---|---|---|---|
| `mathematics_logic` | ADR-0097 + ADR-0110 | `en_mathematics_logic_v1` | All nine ADR-0091 predicates pass; ledger row is **`expert-demo`** (first such promotion, ADR-0110); all three attached lanes meet ADR-0109 shape thresholds on public + holdout. |
| `physics` | ADR-0100 + ADR-0111 | `en_physics_v1` | All nine predicates pass; causal/modal operator coverage meets threshold; ledger row is **`expert-demo`** (second such promotion, ADR-0111); `foundational_physics_ood` 117/117 public + 39/39 holdout; shares `inference_closure` + `fabrication_control` results with math (distinct digest via `domain_id`). |
| `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-0111
ADR-0091 through ADR-0111 establish the current domain-ratification substrate and the expert-demo promotion gate that distinguishes contract-passing from demonstrated:
```text
contract definition (0091)
↓
reviewer trust root (0092)
↓
validator / ledger enforcement (0093)
↓
negative-control fabrication lane (0096)
↓
reasoning-capable domain ratification (0097 / 0100 / 0101 / 0102)
↓
language-specific fluency lane attachment (0103)
↓
expert-demo promotion contract (0106 + 0109 amendment)
↓
worked expert-demo promotion (0110 — mathematics_logic, first)
↓
worked expert-demo promotion (0111 — physics, second; no contract change)
```
No domain claim should be treated as mature merely because a pack exists. `reasoning-capable` means the nine ADR-0091 predicates pass; `expert-demo` requires a reviewer-signed evidence-bundle digest that reproduces byte-for-byte from on-disk lane results.
The contract has been demonstrated end-to-end: refused once honestly (ADR-0107), amended once cleanly (ADR-0109), succeeded against `mathematics_logic` (ADR-0110), and succeeded against `physics` without further contract change (ADR-0111).
