What changed

Adds optional object_type context to the existing runner_v1 dagcbor_validate operation. Rust and TypeScript now validate the complete selected v0.1 CDDL production for all 14 top-level object types; WASM consumes the same Rust implementation. The selector-free legacy path is unchanged.

Adds 103 shared object vectors (17 positive, 86 negative), including every object type, both union-heavy shapes, full CID links, numeric domains, set arrays, limits, Manifest diagnostics, and selector/byte-validation precedence.

Why

Canonical DAG-CBOR alone did not prove that bytes matched the known object type a caller intended to use. Required fields, nested records, unions, fixed widths, and full CID structure therefore lacked one shared cross-language validation boundary. ADR-0012 records the bounded, additive contract.

Docs sync (required)

  • Read and updated docs/llm/DOC_SYNC.md and matching LLM docs
  • Updated human implementing and porting docs
  • Maintainer runbooks and CI workflow names remain unchanged
  • Code, vectors, diagnostics, ADR, NES, CDDL profile, and docs describe the same behavior

Scope

  • Protocol (NES / CDDL / CBOR profile)
  • Conformance (vectors / additive runner input)
  • Core (Rust / TypeScript / WASM consumption)
  • SDK
  • Docs (human / LLM)
  • Tooling (vector/spec drift validation; CI workflow files unchanged)

Invariants and vectors

  • Invariants: INV-OBJ-001 through INV-OBJ-006
  • Added: POS-OBJ-001..017; NEG-OBJ-001..007, 010..023, 030..047, 050..078, 080..086, 089..099
  • Removed: none

Compatibility

This is an additive input to an existing operation. Without object_type, observable dagcbor_validate behavior is preserved. The operation list, output schema, encoded object bytes, and protocol schema major v=1 do not change.

NutrientProfile.uncert remains governed by the existing NES/profile requirement that variance is non-negative. ADR-0012 now explicitly documents migration for producers that used the old ambiguous CDDL comment to store signed metadata there.

Review corrections

  • Clarified uncert compatibility/migration, E2E diagnostic precedence, and the bounded ADR-location exception

  • Made the Rust and TypeScript schema registries exhaustive and drift-resistant; prototype-inherited selectors are rejected

  • CodeRabbit incremental review of bcaa107..1511a31: PASS, no new actionable comments; active unresolved threads: 0

Migration and runtime safety

No database, persisted-state, or wire-format migration changed. Parsing remains bounded by existing depth/map/array/string/payload limits. No locks, queues, network calls, cryptographic changes, or invariant removals were added. No invariant regression introduced.

📝 Walkthrough

Walkthrough

Typed Object Validation v1 adds optional object_type support to dagcbor_validate. Rust and TypeScript validators cover fourteen v0.1 productions, including nested schemas, CID links, limits, unions, set arrays, numeric domains, and deterministic diagnostics. Conformance vectors and synchronized specifications document the behavior.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to 1511a

Typed validation now rejects malformed objects when a caller supplies an object type while preserving the legacy selector-free behavior; this improves input correctness without changing existing callers. The current head still awaits mandatory CI and protected approval, so it is not merge-ready until those gates pass.

Add a positive del ManifestRecord case.

This assertion only covers the rejection path, where op is del and cap_id, chash, and size are still present. No test in this file accepts a well-formed del record. A regression that rejects every valid del record would still pass the suite.

     let del = replace_field(&manifest, "op", text("del"));

Assert that name and literal_t agree with object_type.

The registry keeps object_type, name, and literal_t as three hand-maintained fields. If name drifts from object_type, schema_for_object_type routes a selector to the wrong validator, and the current test still passes. Add a consistency assertion.

Consider keying the registry by ObjectTypeV1 for compile-time completeness.

The array type readonly ObjectSchemaV1[] does not require an entry for every member of OBJECT_TYPES_V1. If an entry is omitted, schemaForObjectTypeV1 returns undefined and a valid selector produces GRAIN_ERR_SCHEMA at runtime instead of failing the build. A Record<ObjectTypeV1, ObjectSchemaV1> makes an omission a type error.

♻️ Proposed typing change
-const OBJECT_SCHEMAS_V1: readonly ObjectSchemaV1[] = [
-  {
-    objectType: "IngredientRef",
+const OBJECT_SCHEMAS_V1: Readonly<Record<ObjectTypeV1, ObjectSchemaV1>> = {
+  IngredientRef: {
+    objectType: "IngredientRef",

Then simplify the lookup:

 export function schemaForObjectTypeV1(name: string): ObjectSchemaV1 | undefined {
-  return OBJECT_SCHEMAS_V1.find((schema) => schema.objectType === name);
+  return Object.prototype.hasOwnProperty.call(OBJECT_SCHEMAS_V1, name)
+    ? OBJECT_SCHEMAS_V1[name as ObjectTypeV1]
+    : undefined;
 }

The hasOwnProperty guard is required. A plain index lookup would let selectors such as "constructor" or "toString" resolve to inherited prototype members.

In `@adr/protocol/0012-typed-object-validation-v1.md`:
- Around line 82-89: The compatibility section of the typed-object validation
ADR must address NutrientProfile.uncert explicitly: either preserve acceptance
of the previous negative-integer form in the validator, or revise the claim that
all valid v0.1 objects remain valid and document migration for values previously
described as variance or metadata.

In `@conformance/vectors/object/NEG-OBJ-085.json`:
- Around line 6-16: Both limit vectors currently encode the exact maximum rather
than an over-limit value. In conformance/vectors/object/NEG-OBJ-085.json lines
6-16, regenerate body to at least 32,769 bytes; in
conformance/vectors/object/NEG-OBJ-086.json lines 6-16, regenerate ext.pad to at
least 8,193 bytes, preserving the expected GRAIN_ERR_LIMIT rejection.

In `@conformance/vectors/object/POS-OBJ-016.json`:
- Line 6: Update the ManifestRecord payload in POS-OBJ-016 to use the allowed
chash key instead of echash, and re-encode the map with chash preceding cap_id

In `@core/ts/grain-ts-core/src/ops/e2e.ts`:
- Around line 46-50: Update the e2e_decrypt diagnostic precedence documentation
in errors.md to state that the size-limit check occurs first, followed by

GRAIN_ERR_TAG_FORBIDDEN, GRAIN_ERR_BAD_CID_LINK, GRAIN_ERR_UNKNOWN_TOPLEVEL_KEY,
GRAIN_ERR_SET_ARRAY_ORDER, GRAIN_ERR_SET_ARRAY_DUP, and GRAIN_ERR_SCHEMA. Do not
change the Rust or TypeScript validation paths.

In `@docs/llm/CHANGE_POLICY.md`:
- Around line 63-68: The ADR location requirement is inconsistent with the Typed
Object Validation v1 policy. Update the policy around “Typed Object Validation
v1” and the corresponding DOC_SYNC entry to explicitly establish whether the
conformance ADR is required or protocol ADR-0012 is the approved exception,
ensuring both documents reflect the same decision.

In `@tools/validate_vectors.py`:
- Around line 243-244: Update the positive coverage tracking around
is_object_vector so object_type is added to positive_object_types only when the
vector is accepted, requiring expect.pass to be true in addition to the POS-OBJ-
vector ID check. Preserve the existing coverage validation behavior for rejected
vectors.

Validation
* Validation tier: Tier 2R — narrow same-task correctness and review corrections after prior Tier 4 conformance proof; mandatory remote full CI remains the final gate.
* git diff --check: PASS
* git diff --cached --check: PASS
* mise exec -- python3 tools/validate_vectors.py: PASS
* mise exec -- python3 tools/check_spec_drift.py: PASS
* mise exec -- python3 tools/check_llm_docs.py: PASS
* mise exec -- python3 tools/ci/check_runner_contract_compat.py: PASS
* mise exec -- python3 tools/ci/check_docs_links.py: PASS (82 Markdown files)
* mise exec -- python3 tools/ci/check_docs_flow.py: PASS
* rustup run 1.86.0 cargo test --manifest-path core/rust/Cargo.toml -p grain-core: PASS (38 unit, 3 property, 10 typed-object tests)
* npm --prefix runner/typescript run build --silent: PASS
* Shared object vectors: Rust 103/103; TypeScript 103/103 PASS
* WASM subset: PASS (25/25)
* Positive-coverage mutation test: PASS — rejected POS-OBJ-001 with expect.pass=false and reported missing IngredientRef coverage.
* Ledger: not applicable — no ledger/change-record requirement applies to this protocol/conformance change family.
* Version: PASS — ADR-0012 classifies the additive runner_v1 input as PATCH; schema major remains 1 and no package bump is required.
* Not run: ./scripts/verify — not required for the Tier 2R correction; mandatory remote CI will provide final-SHA full proof.

Rollback
* git revert HEAD
