Alert reps on account signals (watch the list, post the event, name the owner)

The insight, in the author's words: a rep should not have to go looking — when something happens at an account they own, the event should find them where they already are, with the account and the owner named in the first line. So the list is loaded once, the watches run on their own, and every event becomes one Slack line shaped like "@owner — a key new hire has been filled at Acme: Jane Doe, VP Sales." Nothing here scores, enriches or writes outreach; the rep decides what to do.

Declared inputs

Nothing here ships with a value. Each one is the installer's, not the author's: ask for it, never substitute a plausible default, and where an answer does not exist say which step becomes unavailable rather than guessing. Where a default IS defensible it is named below, and using it means saying so in the output.
