Danijel Martinek 1108e24ea0 chore(deps): backfill library traces for un-cited cluster

Add approved trace files for payload, @trpc/server, @trpc/client, zod,
superjson, @payloadcms/db-postgres, @payloadcms/richtext-lexical, globals,
react, react-dom, vitest, @tanstack/react-query, and all @testing-library/*
packages. All traces dated 2026-05-14, decision: approved, adr: null.

Establishes the baseline so the pre-commit library-decisions gate is
additive (new deps require traces) rather than disruptive (old deps fail
immediately). All 34 trace files pass validateTrace() from schema.mjs.

npm view superjson license

npm view superjson version

pnpm audit --audit-level=moderate

Filter: license

npm view superjson license returns MIT. MIT is on the allowlist.

Filter: types

superjson is authored in TypeScript and ships its own .d.ts declaration files. No separate @types/superjson package is needed.

Filter: maintenance

Actively maintained. Last release < 18 months. Used widely in the tRPC and Next.js ecosystem.

Filter: boundary-fit

superjson is the serialization transformer used by the tRPC layer (@repo/core-shared) to handle non-JSON-serializable types (Dates, Maps, Sets) over the wire. core-testing uses it for mock tRPC client setup. No boundary rules restrict superjson to a specific tier.

Filter: shadow-check

superjson is the sole tRPC-compatible serialization transformer in the workspace. No competing serializer (devalue, msgpackr, etc.) is present.

Filter: eu-residency

superjson is a pure serialization library with no network communication, telemetry, or data transmission. EU residency does not apply.

Filter: cve-scan

pnpm audit --audit-level=moderate reports no advisories against superjson at the time of this trace.

Filter: named-consumer

@repo/core-shared uses superjson as the tRPC transformer. @repo/core-testing uses superjson for mock tRPC client configuration. Named, non-hypothetical consumers exist today.

Prompt: replaces

superjson replaces the default JSON-only serialization in tRPC, which would fail silently when Date objects or other non-JSON types are passed through procedure calls.

Prompt: migration-cost-out

Low. superjson is used as the transformer option in the tRPC router and client configuration — two call sites in core-shared. Replacing it requires swapping the transformer and ensuring the replacement handles the same non-JSON types. No feature package references superjson directly.

Prompt: alternatives-considered

devalue — Supports more types but is less mature in the tRPC ecosystem; superjson is the de-facto tRPC transformer standard.
JSON-only (no transformer) — Rejected because it silently loses type fidelity for Dates and breaks any use case that returns or receives a Date value.
