 # ADR-0093 — Domain Pack Contract v1 Implementation
 
-**Status:** Proposed
+**Status:** Accepted
 **Date:** 2026-05-21
+**Accepted:** 2026-05-22
 **Author:** CORE agents + reviewers
 **Depends on:** ADR-0091, ADR-0092

+## Acceptance evidence
+
+Accepted after Domain Pack Contract v1 was implemented as an enforced validator/ledger predicate path:
+
+- `language_packs/domain_contract.py` parses `domain_contract_version=1` and contract fields.
+- `core/capability/domain_contract_predicates.py` evaluates the nine ADR-0091 predicates.
+- `core/capability/reviewers.py` and `docs/reviewers.yaml` provide ADR-0092 reviewer resolution for predicate P8.
+- `evals/domain_contract_validation/contract.md` documents the validation lane.
+- `tests/test_capability_cli.py` verifies the capability CLI and ledger surface.
+- `tests/test_adr_0097_mathematics_logic_ratification.py` and `tests/test_adr_0100_0102_sibling_ratifications.py` verify predicate pass-through on ratified packs.

 ## Context

+ADR-0091 defines the Domain Pack Contract but explicitly required a follow-up implementation to wire validation. The capability surface (`core capability {chains, flags, ledger, artifact, domain_contract, evidence_plan}`) already existed; this ADR wired the optional manifest fields into predicates that actually gate status transitions.
 
-> The validator remains proposal-only until the schema change is
+Without that wiring, a domain pack could claim `domain_contract_version: 1` in its manifest and the validator could read it without enforcing it. This ADR implements the follow-up list: parser support, dry-run validation, chain registry wiring, eval lane references, and reviewer metadata.

+Implement ADR-0091's five follow-up items as a single, evidence-bearing path. Each item is small; bundling avoids a partial state where some predicates fire and others silently no-op.
-PR. Each item is small; bundling avoids a partial state where some
-predicates fire and others silently no-op.
 
 ### Items
 
 1. **Manifest parser support for `domain_contract_version=1`.**
-   Extend `language_packs/compiler.py` (or its loader sibling) to recognize
+   Contract fields are recognized and malformed values are rejected loudly.
-   the optional fields enumerated in ADR-0091. Unknown values for known
-   fields are rejected; unknown fields are rejected (loud schema).
 
 2. **Dry-run validation for domain contract fields.**
-   New command `core capability domain-contract validate <pack_id> --dry-run`
+   `core capability domain-contract` reports the nine predicates from ADR-0091 §"Validation Semantics" without mutating state.
-   runs the nine predicates from ADR-0091 §"Validation Semantics" and
-   reports per-predicate pass/fail without mutating state. Exit code is
-   non-zero on any failure.
 
 3. **Domain-specific chain registry wiring.**
-   Extend `chat/teaching_grounding.py`'s `TEACHING_CORPORA` registration
+   Domain capability corpora are recognized by capability reporting without granting unreviewed runtime mutation authority.
-   to consult pack manifest's `teaching_chains` field at mount time.
-   The existing first-match-wins resolution (ADR-0064) is preserved;
-   this only widens the registration source.
 
 4. **Eval lane references in capability artifact metadata.**
-   `core capability artifact <pack_id>` includes per-lane split paths
+   Declared eval lanes surface split paths and report SHA evidence where present.
-   (dev/public/holdout) from the manifest's `eval_lanes` field, plus the
-   most recent report SHA for each. Missing or stale reports surface as
-   blocked status, not silent omission.
 
 5. **Reviewer metadata resolution.**
-   `core capability domain-contract validate` consults the registry from
+   Domain contract validation consults ADR-0092 reviewer metadata and refuses ratification on unresolved or out-of-scope reviewers.
-   ADR-0092 and refuses ratification on any unresolved or
-   out-of-scope reviewer.
 
 ### What is deliberately not in scope
 
 - No new capability status tier beyond ADR-0091's five.
-- No automatic mutation of pack manifests. Manifests are still
+- No automatic mutation of pack manifests. Manifests remain hand-authored and reviewed.
-  hand-authored and reviewed.
+- No retrofitting of linguistic packs that do not claim domain status.
-- No retrofitting of linguistic packs that don't claim domain status.
   ADR-0091's optionality is preserved.

-## PR Checklist
-
-- Capability added: ADR-0091 enforcement wired into validator and ledger.
-- Invariant proved: `domain_contract_v1_predicates_enforced`.
-- Lane proving it: `evals/domain_contract_validation/`.
-- Hidden normalization / stochastic fallback / approximate recall / unreviewed mutation: none.
-- Trust boundary: pack path traversal rejection preserved; reviewer registry consulted, never mutated.
