 # ADR-0100 — Physics Reasoning-Capable Ratification
 
-**Status:** Proposed
+**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 `physics` became a mechanically ratified `reasoning-capable` ledger row:
+
+- `language_packs/data/en_physics_v1/manifest.json` carries Domain Pack Contract v1 fields.
+- `teaching/domain_chains/physics_chains_v1.jsonl` supplies reviewed active chains.
+- `tests/test_adr_0100_0102_sibling_ratifications.py` pins:
+  - all nine predicates pass for `en_physics_v1`
+  - the ledger row status is `reasoning-capable`
+  - provenance points at `adr-0100:reviewed:*`
+  - `expert_demo` remains false
+  - claimed operators `causal` and `modal` meet chain coverage
+  - declared lanes include `foundational_physics_ood`, `inference_closure`, and `fabrication_control`

 ## Context
 
 The physics substrate is structurally complete:
 
 - `language_packs/data/en_physics_v1/` ships with manifest, lexicon, glosses.
 - `teaching/domain_chains/physics_chains_v1.jsonl` exists.
-- `evals/foundational_physics_ood/` exists with dev/public/holdouts.
+- `evals/foundational_physics_ood/` exists with dev/public/holdout coverage.
-- `docs/gaps.md` marks every physics gap closed:
+- `docs/gaps.md` marks physics gaps closed.
-  `gap:physics_pack_absent`, `gap:physics_causal_chains_below_threshold`,
+- Chain coverage and intent-shape coverage satisfy ADR-0091 predicates.
-  `gap:physics_modal_chains_below_threshold`,
-  `gap:physics_intent_shapes_below_threshold` — all `[x]`.
-- Chain coverage: causal=8, modal=8 (≥8 per claimed operator family ✓);
-  five intent shapes populated (cause, comparison, correction, procedure,
-  verification — ≥3 ✓).

 ## Decision
 
 Ratify `en_physics_v1` as `reasoning-capable` under ADR-0091 by emitting

+- Second ratified `reasoning-capable` domain.
-- Invariant proved: `physics_reasoning_capable_ledger_row`.
+- Demonstrates the ADR-0091 contract is not math-only.
-- Hidden normalization / stochastic fallback / approximate recall / unreviewed mutation: none.
+- Provides an additional domain source for later showcase composition.
-- Trust boundary: manifest edit through reviewed flow; checksums unchanged.
