DOC-6836 Rename resolveCredentials() to resolveCredentialsAsync() in Lettuce AMR docs [PARKED]

[andy-stark-redis]

Updates the Lettuce Azure Managed Redis (AMR) / Entra ID auth page for the upcoming
credential-provider SPI rename in Lettuce: RedisCredentialsProvider →
CredentialsProvider, and its resolveCredentials() method → resolveCredentialsAsync().
Two call sites in amr.md are updated to the new
async name.

⚠️ DO NOT MERGE YET. This is written against unmerged upstream PRs
(redis/lettuce#3838,
#3829,
#3837) that currently target a
feature/reactor-optional-1 branch, not main. The rename only reaches our readers once
the separate redis-authx-entraid artifact rebuilds against the new Lettuce SPI and
releases. Merging now would leave the page documenting a method name that no released
artifact exposes. Pick up with /pickup <this PR> when the trigger fires.

Park manifest

Ticket: DOC-6836
Parked at: 2026-07-13
Trigger to pick up: redis-authx-entraid publishes a release (tag > v0.1.1-beta2) whose
TokenBasedRedisCredentialsProvider exposes resolveCredentialsAsync() — i.e. it has adopted
the renamed Lettuce SPI. (Precursor: the Lettuce PRs below merge to main and ship in a Lettuce release.)
Labels: parked, do not merge yet

jvm-redis-authx-entraid — the artifact our page actually pins	no formal releases; latest tag v0.1.1-beta2; page pins 0.1.1-beta1 (still exposes resolveCredentials())	gh api repos/redis/jvm-redis-authx-entraid/tags --jq '.[0:5][].name'

Observed shape the page assumes (confidence: LOW)

• The credential-provider SPI method is renamed resolveCredentials() → resolveCredentialsAsync()
  (return type unchanged: CompletionStage<RedisCredentials> / reactive Mono chain still .doOnNext(...).block()).
  LOW — taken from the unmerged #3838 diff against a feature branch, not a released artifact.
• TokenBasedRedisCredentialsProvider (the class our page uses) keeps its name; only its
  method is renamed. LOW — same source; the class in the diff lives in Lettuce core
  (io.lettuce.authx), whereas our page consumes it from the separate redis-authx-entraid
  package (redis.clients.authentication). The rename must propagate across that repo boundary
  before it's real for us; that propagation is unverified.
• Three overlapping PRs with divergent verbs (#3837 deprecate on main, #3838 remove on
  the feature branch): the end-state exposed to users — remove vs. deprecate-with-alias — is not
  yet settled.

Re-check checklist

• (highest risk) Confirm which redis-authx-entraid release exposes resolveCredentialsAsync(), and bump the pinned version at amr.md lines ~43 and ~51 (currently 0.1.1-beta1) to match. The page is intentionally inconsistent while parked — new method name, old version.
• Confirm the method rename resolveCredentials() → resolveCredentialsAsync() actually landed (not renamed again, e.g. resolveAsync()), and that the return-type / .doOnNext(...).block() usage in the two snippets still compiles.
• Determine whether resolveCredentials() survives as a deprecated alias (#3837 "deprecate") or is removed (#3838 "remove"). If it survives, our edit is preferred-not-required and there's no reader-facing break — note this in the finalize commit.
• Confirm TokenBasedRedisCredentialsProvider (and EntraIDTokenAuthConfigBuilder) class names are unchanged in the released artifact; the page uses them ~10 times.
• Sweep the rest of content/develop/clients/lettuce/ for any newly-relevant SPI mentions (CredentialsProvider, subscribeToCredentials, supportsStreaming) introduced by the wider "reactor-optional" refactor — none today, but the umbrella change is broad.

On pickup, then

When the trigger fires, run /pickup <this PR>: it re-fetches each pinned source, diffs it
against the snapshots above, reconciles the docs, and takes the PR through the normal
/reflect → /finalize pipeline to merge. The do not merge yet guard holds until
/finalize completes.

Note

Low Risk
Documentation-only renames in example snippets with no runtime or security impact; merge timing depends on matching released client APIs.

Overview
Updates the Lettuce Azure Managed Redis (AMR) / Entra ID page so sample code matches the upcoming Lettuce credential-provider SPI rename: resolveCredentials() → resolveCredentialsAsync().

Both Java snippets in amr.md are touched—the standalone “test credentials” example and the commented optional test in the full connection sample. The reactive chain (.doOnNext(...).block()) is unchanged.

Note: The PR description marks this as parked until redis-authx-entraid ships against the new SPI; the doc still pins dependency version 0.1.1-beta1, so method names and artifact version may be intentionally out of sync until pickup.
