YES
## What kind of change does this PR introduce?
Docs update. Restructure, mostly moved lines, plus a tense fix in a
shared partial.
## What is the current behavior?
Context, procedure, and reference material are interleaved, so
background reading interrupts the action path.
- The page never states which key to use as an answer. You infer it from
a five-column reference table.
- Finding a key is a fragment inside an admonition, placed above the
page's own definition of an API key.
- Rotating a leaked key, the only procedure on the page, is the last H3.
- The "Changes to API keys" notice narrates a past change in future
tense, and "They will be deprecated" has no antecedent in its paragraph.
## What is the new behavior?
Group the guide into context, procedure, and reference sections, per
CONTRIBUTING § Guides on mixed information types.
- Lead with "Which key do you use?", a decision table keyed on where the
code runs. Section navigation sits directly below the intro.
- Collect the conceptual sections under "How API keys work" and give
publishable and secret keys parallel headings.
- Promote both procedures into "Find and use your keys". Rotation is now
an ordered procedure.
- Move the enumerated secret key rules into "Security reference",
grouped under bold labels by the kind of mistake each prevents, and
leave a short danger admonition where secret keys are introduced.
- Promote the five-sentence coexistence admonition to its own section.
Admonitions are for short warnings.
- Rewrite the shared deprecation partial for timeless documentation:
present tense, no dangling "They", no "now". The partial renders on five
pages.
- Pin a stable anchor on the rotation heading and update the one inbound
link, in the rotating-anon-service-and-jwt-secrets troubleshooting
entry.
- Align link text across docs for this guide. Twenty-one links pointed
at it under fourteen labels, including two that named the wrong
destination. Rule: when a link means the guide, the text is "API keys";
when it means a specific key or section, the specific text stays. Twelve
now share "API keys", up from three.
Review with `git diff --color-moved=zebra`.
## Additional context
PR 2 of 4. Base is #49795. Includes the link-text alignment previously
opened as #49866.
## Manual testing
1. Open the API keys guide on the deploy preview.
2. Check the table of contents. It shows three groups: How API keys
work, Find and use your keys, Security reference.
3. Open the rotating-anon-service-and-jwt-secrets troubleshooting entry
and follow "Rotate a leaked or compromised key" under Further readings.
It lands on the renamed heading.
4. Open the Realtime Broadcast guide and check the "Changes to API keys"
notice. It reads in present tense there too.

## Summary by CodeRabbit
- **Documentation**
- Updated API key guidance to explain the transition from legacy `anon`
and `service_role` keys to publishable and secret keys by the end of
2026.
- Reorganized the API keys guide with clearer key-selection guidance,
security recommendations, usage examples, and rotation steps.
- Updated troubleshooting references to point to the revised leaked-key
rotation guidance.

YES
## What kind of change does this PR introduce?
Resolves MDX linting errors related to "simple" where it applies.
There was a couple cases that did not apply. For example, a product with
"Simple" in the name.
These changes are made in context, either by removing or using a more
descriptive synonym like "minimal" or "basic".
## Tophatting
1. Read each of the diffs.
2. See that the text still makes sense in context.
For extra due diligence, you can run `pnpm lint:mdx` locally and see the
'simple' errors that remain and whether they are worth addressing.

## Summary by CodeRabbit
* **Documentation**
* Updated many guide, tutorial, and troubleshooting pages with clearer
“basic”/“minimal” wording across setup steps, local testing
instructions, security cautions, and RLS guidance.
* Refined headings, example descriptions, and inline comments for
consistency (including deployment, MCP, metrics API, and search/function
phrasing).
* Improved readability with small snippet formatting tweaks (whitespace
plus import/comment ordering) and added a self-hosting debugging note
for Envoy admin endpoints via a short-lived `curl` container.

Pretty simple change, we are still referencing legacy service role API keys in the docs. This only updates to reference the current preferred solution with secret API keys
