+# OpenSpec Change: crypto-curve-spec-conformance
+
+- **Change ID**: crypto-curve-spec-conformance
+- **Package**: `@suaveplan/crypto-curve`
+- **Status**: PROPOSED
+- **Date**: 2026-04-26
+
+## Summary
+
+Add `**Verified by:**` lines to every requirement in `openspec/specs/crypto-curve/spec.md` and pin previously-unverified structural scenarios (per-primitive replaceability, GENERATED-banner check, Phase-0.5 consistency gate, dangerous-tier flip-gate runtime reflection, native-stub state) with `tests/spec-conformance.test.ts`. No public-API or behavioural changes.
+
+## Current state
+
+`@suaveplan/crypto-curve` ships secp256k1, ed25519, x25519, p256 with the per-primitive replaceability layout. Each primitive has a `noble.ts` (active) and a `native.ts` stub that throws `PrimitiveNotImplemented`. Per-feature unit tests cover sign/verify, ECDH, RFC vectors, malformed-input rejection, and `verify` boolean contract. The structural scenarios (impl-file presence, GENERATED banner, vendored noble Phase-0.5 gate, dangerous-tier flip gate, constant-time stub state) were not pinned, and no requirement carried a `**Verified by:**` annotation.
+
+## What changes
+
+1. Annotate every requirement in the folded `openspec/specs/crypto-curve/spec.md` with a `**Verified by:**` line.
+2. Add `tests/spec-conformance.test.ts` covering layout, banner, Phase-0.5 consistency, native-stub state, and the dangerous-tier runtime reflection.
+3. `bun scripts/openspec-conformance.ts @suaveplan/crypto-curve` exits 0.
+
+## Impact
+
+- Public API unchanged.
+- One new test file (~120 lines).
+- `openspec/specs/crypto-curve/spec.md` gains 5 `**Verified by:**` blocks.
+- Coverage stays 100/100/100/100.
