/**
|
|
* Daily change digest (PRODUCT.md P1.1) — diff today's signal snapshots
|
|
* against the previous ones, join with stored news catalysts, and post to
|
|
* Discord (DISCORD_WEBHOOK_URL) or print to the terminal.
|
|
*
|
|
* RUN ORDER MATTERS — screen first, digest second:
|
|
* 30 16 * * 1-5 cd /path/to/app && npm run screen:daily && npm run digest:daily
|
|
*
|
|
* Usage:
|
|
* npm run digest:daily # today
|
|
* npm run digest:daily -- 2026-06-09 # specific day
