Run the Social Media Calendar standing cycle now.

At the morning run, rebuild today's engagement opportunities, verify today's links and append only the far-end Calendar day when fewer than seven future days remain. At the afternoon run, touch tomorrow only for material trend replacements and refresh stale engagement links.

Use the exact row mix, channel voice, source rules and writing shapes in skill.md. Check Used Sources before choosing anything. Never publish, schedule, send or spend. Read back every changed row and report the lineup, engagement URLs, ready/blocked/replaced counts and next fixed check. If nothing changes, log a clean no-op.
