docs: add a guide to rotating API keys without downtime - #5095
Adds docs/rotate-api-keys.mdx, a how-to for replacing a Trigger.dev API key so that both keys work at the same time and no request fails while you switch over.
It covers:
Individual API keys: create a replacement, roll it out, check Last used, then revoke the old key.
Root key: regenerate with Keep the previous key working for 24 hours, roll out within the window, and use the Vercel sync checkbox.
A key that may have leaked: for a leaked root key, move services to an individual API key first, then regenerate with Revoke the previous key immediately. That revokes the key straight away and nothing goes down.
Deployed tasks: we inject TRIGGER_SECRET_KEY into each run, so they don't need a redeploy after a root key rotation.
The page is registered next to apikeys in docs.json. The "Expire and revoke keys" section of apikeys.mdx now links to it.
Related: #5050 adds a short "Regenerate the root key" section to apikeys.mdx. The two don't conflict: this page is the step-by-step procedure, and #5050 describes the dialog options.
Open questions for review
Runs already executing at rotation time: they keep the previous root key in their environment. Do runs that use the SDK with that key fail if the root key is revoked immediately, or does the per-attempt run token cover them? The same question applies to runs that last longer than the 24-hour window. The page avoids making a claim either way.
Root key row: is Last used shown for the root key too, or only for individual keys? The page only relies on it for individual keys.

Review comments at @docs/rotate-api-keys.mdx:
- Line 41: **Note that an unchanged Last used time does not prove an infrequent
service has switched.**
Step 3 uses **Last used** as the check before revocation. A service that runs
rarely, such as a monthly job or a scheduled CI workflow, may not send a request
for a long time after you deploy the new key. Its old key then shows no
activity, even though the service still uses it. If you revoke at that point,
the service fails on its next run.

- Line 78: **Document the immediate-revocation trade-off for leaked individual
keys.**
The root-key guidance already covers immediate revocation when services cannot
be updated quickly and states that those services fail until they receive the
replacement. Add the same conditional choice to the individual-key guidance
without changing the routine rotation procedure.

- Line 88: **Disable the Vercel sync before you regenerate the root key.**
The leaked-root procedure does not tell readers to clear **Also update
TRIGGER_SECRET_KEY in Vercel**. The guide's root-key section leaves that box
checked by default. If it stays checked, regeneration writes the new root key to
Vercel. That replaces the individual key from the replacement step. The next
Vercel deployment then runs with a root key, which contradicts the step's
statement that services no longer use the root key.

Walkthrough
The documentation adds a guide for rotating individual API keys and root keys. It describes replacement, rollout, verification, and revocation steps, including the default 24-hour validity period for a previous root key after regeneration. It also covers leaked keys and possible authentication failures. The guide is added to the Fundamentals navigation and linked from the existing API key revocation guidance.
Merge Risk: Low · up to b5de4
The new guide is helpful, but three steps could lead readers to an unintended outcome during rotation. In the leaked-root procedure, Vercel could be switched back to the root key. Revoking an individual key based only on Last used could break a rarely running service. The individual-key leak guidance does not mention immediate revocation. These are quick wording fixes worth making before merge.

Explanation
The title "docs: add a guide to rotating API keys without downtime" matches the main change, which adds docs/rotate-api-keys.mdx, a how-to for rotating API keys so both keys work during the switch. It follows the conventional docs: prefix and names the primary change specifically.
Full details: Description check
Explanation
The description follows the repository template in substance. It explains what the new page covers (individual keys, root key, leaked keys, deployed tasks), notes the docs.json registration and the apikeys.mdx link, and lists open questions for review. It does not fill in the template's Closes #<issue> line, the checklist, the Testing section, the Changelog section, or the Screenshots section, and it does not state whether the checklist items were completed. The description covers the content well but leaves several template sections blank.
Resolution
Consider adding the Closes #<issue> reference, completing the checklist (contributing guide, PR title convention, testing), and filling in the Testing, Changelog, and Screenshots sections or marking them not applicable. Note that the template's Closes line and checklist are the parts still missing.

**The root key leaked.** Regenerating with a 24-hour overlap leaves the leaked key valid for up to a day. Revoking it immediately breaks every service that still uses it. To avoid both, move your services off the root key first:
