Summary

• Regenerated the Java SDK from the current Voice Agent Think Live API-reference branch.
• Aligns conversational_behavior with the source contract: the server always sends it, while the SDK preserves existing fluent builders and Optional APIs by emitting default when older callers omit it.
• Reapplies all manual compatibility, WebSocket, hashCode, union-default, and model-catalog patches; Fern does not yet cover them.
• Preserves conditional Agent unknown-frame compatibility and all existing Think Live controls/events.
• Deletes all transient .bak files.

Validation

• ./gradlew spotlessCheck test compileExamples

Content looks right and the Docker gate passes (spotlessCheck compileJava compileExamples unitTest, 2m52s). Prod probe today shows conversational_behavior on every ConversationText and History frame, Think Live off and on, so required is correct.

Should-fix

1. A wire "conversational_behavior": null now NPEs inside the swallowed catch and the frame falls through to onAgentV1History instead of onConversationText, with no onError. On 0.11.2 it parsed as empty. Restore the null policy on the setter at AgentV1ConversationText.java:244:

@JsonSetter(value = "conversational_behavior", nulls = Nulls.SKIP)

and add a wire test next to dispatchesConversationTextWithoutBehaviorAsDefault that sends null and asserts DEFAULT. Prod never sends null today, so this is latent, but it is a wrong-handler delivery.

2. The AGENTS.md freeze note says the shim "preserves source and binary compatibility". Signatures are unchanged, but conversationalBehavior(null) now throws NPE (both overloads) and Optional.empty() resolves to DEFAULT. One sentence saying so keeps the note honest.

Nits

• ConversationalBehaviorStage is public and implemented by the Builder but no stage ever returns it. Dead API that a future regen could silently drop; either leave it out of the hand patch or note it as intentionally dead.
• .fernignore lists CLAUDE.md, which does not exist in the tree (pre-existing, not from this PR).
• The PR title becomes the 0.11.3 release bullet. Suggest squashing as fix(agent): ConversationText always carries conversational_behavior so it tells a developer something.

Approving content; I'd hold release PR #135 until deepgram-docs #1283 merges so docs and SDK ship together.

Re-reviewed at 5fdeba7. The null case is handled (nulls = Nulls.SKIP on the setter) and the new MockWebServer wire test proves a null on the wire reaches onConversationText as DEFAULT. The retained ConversationalBehaviorStage is now documented. Docker gate at this head: spotlessCheck compileJava compileExamples unitTest, BUILD SUCCESSFUL in 2m49s.

One wording nit left in AGENTS.md: the note still says the shim "preserves source and binary compatibility" but conversationalBehavior(null) (either overload) now throws NullPointerException. One sentence saying so is enough; not holding on it.

Approving. Hold release PR #135 until deepgram-docs #1283 merges so docs and SDK ship together.
