**Blocker: no approved pieces to schedule.** Evidence gathered: - `~/content-queue/week-2026-W17/_review-state.json` → `status: awaiting_review`, `pieces: {}` (zero approvals recorded) - Week dir contains 7 composed LinkedIn pieces (lun/mar/mié/jue/vie + 2 extras) per `slots.yaml` (publish 14:00 CDMX, Mon 2026-04-20 → Fri 2026-04-24) - `~/content-queue/week-2026-W18/` only has 1 extra piece, nothing to schedule - `~/bin/buffer-post.sh` present; not invoked — externally-visible, requires approved pieces first No `buffer-post.sh` calls were made.
