+# Capability Spec Delta: error (spec-conformance)
+
+**Package**: `@suaveplan/error`
+**Status**: PROPOSED
+
+This delta annotates each existing requirement in `openspec/specs/error/spec.md` with a `**Verified by:**` line. No requirement semantics change.
+
+## MODIFIED Requirements
+
+(See `openspec/specs/error/spec.md` for the full requirement bodies; this delta only records the verification mapping.)
+
+| Requirement | Verified by |
+|---|---|
+| Zero workspace and runtime dependencies | `tests/dep-graph.test.ts` AND `tests/no-disallowed.test.ts` |
+| SuaveplanError base class | `src/base/suaveplan-error.spec-conformance.test.ts` AND `src/base/suaveplan-error.test.ts` |
+| Stable error-code registry helper | `src/codes/define-codes.test.ts` AND `src/codes/define-codes.spec-conformance.test.ts` |
+| Cause-chain traversal is cycle-safe and depth-bounded | `src/causes/walk-causes.test.ts` |
+| Lossless wire serialization | `src/serialize/serialize.test.ts` |
+| Redaction at the serialization boundary | `src/serialize/serialize.test.ts` AND `src/redact/sensitive.test.ts` |
+| OTel span event adapter | `src/otel/to-span-event.test.ts` |
+| i18n-ready messages | `src/i18n/resolver.test.ts` AND `src/base/suaveplan-error.test.ts` |
+| Test coverage at 100% | `src/serialize/serialize.test.ts` (property-based) + coverage gate |
+
+## Newly added tests in this change
+
+- `src/base/suaveplan-error.spec-conformance.test.ts` — pins type-level "subclass narrows code union" and runtime "stack contains subclass name".
+- `src/codes/define-codes.spec-conformance.test.ts` — pins "code values are literal-typed" type-level scenario.
