Question#
Which film lenses ship first?
Recommendation#
Adopt the proposal's recommended set (§26.6): playback/annotation, camera, performance, narrative, and sound — with costume and animation following. These five cover the learner-filmmaker journey end to end while limiting analyzer surface; costume (Aglaea) and animation (Aja) follow once media-region grounding and real extraction exist.
Options considered#
- All lenses at once — rejected: violates YSD-0019 (automation only after correction/calibration exist) and spreads evaluation thin.
- Narrative-only start — rejected: leaves the workspace text-shaped and under-serves performance/camera personas.
Consequences#
- Section 9 lens items are sequenced by this set; the prohibited-inference analyzers flagged in section-29-evidence.md stay excluded regardless of lens order.
Machine-enforced outcome (once approved)#
Lens registry feature flags (YSD-1014) enable exactly the approved set; unapproved lenses return unsupported.
