PR Summary

Low Risk
Low risk: a config-only change that restricts dynamic routes to generateStaticParams output, affecting routing/404 behavior but not core business logic or data handling.

Overview
Landing dynamic routes now reject unknown slugs. Adds export const dynamicParams = false to the blog post, integration, and model provider/model pages so only slugs returned by generateStaticParams are valid.

This makes invalid /blog/[slug], /integrations/[slug], and /models/[provider]/[model] (and /models/[provider]) URLs return the app’s 404 page rather than attempting to render and throwing client/runtime errors.

Greptile Summary

Adds export const dynamicParams = false to all four landing page dynamic routes (blog, integrations, provider, and model detail). With this export, Next.js returns a 404 for any slug not emitted by generateStaticParams instead of attempting to render the page and throwing a client-side exception.

Confidence Score: 5/5

Safe to merge — minimal, targeted change that applies the standard Next.js pattern for 404-on-unknown-slugs across all landing dynamic routes.

All four files receive only the single-line export const dynamicParams = false addition, which is the idiomatic Next.js mechanism for this use case. Each route already had a correct generateStaticParams implementation, so the new export slots in without any other changes needed. No logic, state, or data-fetching is affected.

No files require special attention.

Important Files Changed

Filename	Overview
apps/sim/app/(landing)/blog/[slug]/page.tsx	Added dynamicParams = false to statically gate blog post slugs; correct and consistent with the existing generateStaticParams + revalidate setup.
apps/sim/app/(landing)/integrations/[slug]/page.tsx	Added dynamicParams = false; the existing notFound() guard inside the render function is now unreachable but harmless defensive code.
apps/sim/app/(landing)/models/[provider]/[model]/page.tsx	Added dynamicParams = false to the model detail route; pairs correctly with generateStaticParams iterating ALL_CATALOG_MODELS.
apps/sim/app/(landing)/models/[provider]/page.tsx	Added dynamicParams = false to the provider listing route; pairs correctly with generateStaticParams iterating MODEL_PROVIDERS_WITH_CATALOGS.
