This PRs unifies the caching story across the docs, making Cache
Components the happy path, while still providing guidance to users in
the old model. However, instead of explaining the old model and its
caching layers, we've created a new guide focusing on what APIs to use
and when.
This follow-up PR aligns terminology across the docs:
https://github.com/vercel/next.js/pull/90589
## IA updates
Getting Started section:
- Improves Getting Started progression:
- **Before:** CC → Fetching Data → Updating Data → Caching and
Revalidating (old and new model mixed)
- **After:** Fetching Data (Dynamic) → Mutating Data (Dynamic) → Caching
with CC (Prerendering) → Revalidating with CC.
- New: `caching.mdx` (CC-first)
- Structure:
- Enabling Cache Components
- Data vs UI-level caching
- Working with request time APIs
- Passing request values to cached functions
- Working with non-deterministic operations
- Working with synchronous operations
- How rendering works (PPR and static shell story)
- New: `revalidating.mdx` (CC-first)
- Explains how to use `cacheLife` and `cacheTag`
Guides Section:
- New: `caching-and-revalidating.mdx` (Previous Model)
- For users who are not using CC, includes `fetch` options and route
segment config
- Moves route segment config options that don't apply to CC from API
reference to this guide (for easy archiving in the future).
- New: `migrating-to-cache-components.mdx` (WIP)
- Del: `caching.mdx` 😌
## Terminology
We should remove caching layers from the docs. Users only needed to be
exposed to them when they were configured independently, but the new CC
APIs work across layers.
To make it easier to review this PR, I'm consolidating terminology and
fixing broken links in a new PR:

This PR removes the deprecated sync access to Dynamic APIs.
- Removed UnsafeUnwrapped* types.
- Replaced `as unknown as UnsafeUnwrapped ` type casts to `as any` for
dev warning.
- Removed tests that expected sync access to not error.
- Removed `UntrackedExotic` functions.
- Modified tests that were accidentally doing sync access.
- Updated warnings to emphasize that it is a Promise and must be
awaited.
- Removed paragraph that states access is allowed from
`errors/sync-dynamic-apis.mdx`.
