Face redaction is compliance plus framing: huge blocks look like stickers, tiny ones still look familiar
`face-privacy-mosaic` fits press walls, school activities, retail camera stills, and volunteer archives. Mosaics reduce identifiability, yet missed temples, jaw shadows, or mask top edges can leave profile cues a colleague still matches. Hair on dark backgrounds often shows gray halos where cells blend into untouched pixels—fine on a phone, obvious in CMS hero crops. Heavily compressed JPEG sources plus coarse cells can beat against 8×8 compression grids and look dirty in thumbnails. Masking only the hero face while leaving bystanders untouched can still break minor-protection or consent policies. Batch jobs need one cell size and alignment policy or mixed outputs look careless. Re-cropping a horizontal master to a vertical cover can shift cells off faces—revalidate per aspect ratio. Compared with pure blur, hard squares signal intentional redaction, useful when internal training keeps originals while externals get marked scope notes.
Face privacy mosaic workflow
- In `face-privacy-mosaic`, list every face including partial profiles, then preview a few cell sizes.
- Check hairlines, mask rims, and glasses glare for leftover cues; review at thumbnail scale.
- Export, quarantine masters, and note redaction scope and date on the publish record.
