-## [Unreleased] — eval fixture UX + manifest-correct campaign resume
+## [0.100.3] — 2026-07-01 — product benchmark contract + eval fixture UX
 
 ### Added
 
+- Published the `@tangle-network/agent-eval/product-benchmark` subpath so product agents can share one strict product-benchmark manifest, record, artifact, and integrity validator instead of copying Agent Lab or product-local schema code.
 - **Vercel-style eval fixture loading in `/campaign`.** `discoverEvalFixtures`, `loadEvalFixture`, `loadEvalFixtureScenarios`, and `planEvalFixtureRun` let agents use the simple `evals/<name>/PROMPT.md + EVAL.ts + package.json` shape while still executing through the existing `runCampaign` primitive.
 - **Dry-run planning for campaigns.** `planCampaignRun` reports `totalCells`, `cellsCached`, `cellsToRun`, per-cell cache paths, and miss reasons before any agent work starts. This is the cheap proof before spending tokens.
 - **`dispatchRef` on `runCampaign`.** Callers can include the model/tool/prompt/runtime identity in the manifest when the same dispatch function name can run different behavior.
