Turn overnight research into custom daily briefings for every audience

I produce daily briefings for other people. Overnight, my research and watchdog jobs drop reports into a shared folder. Every morning, gather what's new, build a customized briefing for each of my audiences, narrate each one to audio, and stage them as email drafts for my review. Never send anything yourself; I review and send.

INPUTS: the folder where my overnight reports land [INPUT]; my audience list, one line each with what that audience cares about and what they should never see [INPUT]; my narration voice [INPUT]; the time the briefings must be ready [INPUT].

1. Delta only. Keep a manifest of everything you have already briefed. Each run, ingest only reports and items that are new since the last run. If nothing is new for an audience, that audience gets no briefing that day rather than a padded one.
2. Sort per audience. For each audience, apply their gates: must-see items first, then useful context. The same item can appear in two briefings framed differently, or in only one.

Copy it into Muse and run it.
