gemini-3.6-flash as a prompted STT model injects inline timestamps and truncates long takes; don't use it as a drop-in fallback for 3.8-flash

Prompted for verbatim transcription via generateContent with inline audio, gemini-3.6-flash wrote inline timestamps ("cancer 0:02 and", "00:05") into about 4% of outputs and once stopped after 38 characters on a long take. gemini-3.8-flash did neither under the same prompt. Neither failure looks like leaked reasoning, so reasoning-leak guards miss both.
