 - **WHEN** the simulated microphone transport runs out of frames before the expected turn completes
 - **THEN** the command SHALL fail with a structured error instead of waiting indefinitely

+### Requirement: Real provider live fixture acceptance
+The system SHALL support scripted full-chain acceptance that drives the live pipeline with generated microphone PCM while using real local speech providers, the configured cloud LLM, and local TTS/playback capability.
+
+#### Scenario: Real provider fixture completes one turn
+- **WHEN** generated wake and formal question PCM frames are passed through the live pipeline
+- **THEN** the pipeline SHALL use the real local KWS, local VAD, local denoiser, local STT, configured cloud LLM, local TTS, and playback provider path to complete a wake-to-standby turn
+
+#### Scenario: Real provider fixture completes repeated turns with temporary context
+- **WHEN** two generated wake/question turns run in one process and the first turn gives a user fact
+- **THEN** the second LLM request SHALL include the first turn's user and assistant history from process-local memory
+- **AND** no history SHALL be read from disk or persisted after the process exits
+
+#### Scenario: Zero playback drain still flushes queued echo
+- **WHEN** ACK or TTS playback completes and `OWNER_POST_PLAYBACK_DRAIN_MS=0`
+- **THEN** the runtime SHALL call `flush_input()` once to clear already queued playback echo
+- **AND** it SHALL NOT perform an additional timed microphone read-and-discard loop
+
+#### Scenario: No acknowledgement playback is configured
+- **WHEN** `OWNER_WAKE_ACK_TEXT` is empty and no wake acknowledgement audio is played
+- **THEN** the runtime SHALL NOT run post-playback drain before capture starts
+
+#### Scenario: Fixture transport preserves future frames
+- **WHEN** a memory or fixture transport represents pre-generated future microphone frames
+- **THEN** tests SHALL be able to configure flush to record the cleanup call without deleting those future frames
+
 ### Requirement: Wake acknowledgement before recording
 The live runtime SHALL provide an audible local acknowledgement after local wake detection and before it starts recording the user's formal question.
