Three delivery modes compared on the axes teams ask about first. Builder lane stays the default recommendation for individual engineers who want grading and certificates.
| Capability | Observer | Builder Recommended | Guild |
|---|---|---|---|
| Mentor feedback | Read-only notes | Graded labs + two critiques | Shared SLA channel |
| Certificates | Not available | After rubric pass | Per contract |
| Customization | None | Optional add-ons a la carte | Design tokens + templates |
| Cohort pacing | Self-paced viewing | Published weekly cadence | Aligned to your release train |
| Live seat cap | N/A | Published per block to keep ratios | Negotiated per guild |
