Read expected source master
Synthetic placement requires rendition from master M2. File R34 is labelled “M2-square” but build record says derived from M1; R35 is labelled “M2-wide” and derived from M2. Local acceptance requires actual source M2. There is no authorised equivalence between masters and no image is generated here.
| Rendition | Declared/derived source | Action |
|---|---|---|
| R34 square | M2/M1 | Regenerate from M2 |
| R35 wide | M2/M2 | Keep source evidence |
Compare derivation evidence
- Match placement requirement to M2
- Read build source for each rendition
- Reject R34 relabelling
- Request M2 regeneration and new evidence
If derivation evidence is absent, source lineage remains unknown even with an M2 filename.
How many renditions require regeneration?
Show the worked answer
One, R34. R35 already has the supplied M2 derivation evidence.
Request actual regeneration
| Case | Decision or result | Reason |
|---|---|---|
| Rename R34 only | Reject | Build source stays M1 |
| New R34 built from M2 | Candidate eligible | Actual source matches |
Keep old rendition and new derivation identities distinct. Compare the regenerated content with the placement brief before closing.
