published. Three lanes: Skills (new skills from /skill-forge, CATALOG changes),
Products (business cases, retros, RCAs, comms showing active system usage), and
Prototypes (overnight builds, hackathon outputs, new repos). Feeds live at Skillz
Portal or GitHub Pages. Execs subscribe via Outlook, SharePoint, Slack, or browser
with zero behavior change. Auto-triggered by /skill-forge and /overnight-build.
Generates weekly Friday digests. Teams channels subscribe natively via RSS.
Commands: add, generate, digest, status.
