Turtle Sanctuary upper-leaf cleanup:three rejected local drafts
The complete original remains authoritative. Three localized alpha-mask studies preserve every original RGB value and every RGBA pixel outside their masks,but native light/dark detail inspection still finds stippled exterior residue. None is accepted or registered. v1 changes1,733 alpha values;v2 changes2,192;v3 changes2,482. All three preserve every row223 onward,including reef,water,turtles and ground-contact shadow. An independent PNG decoder verifies the v1 mask invariants;v2/v3 have decoded generation-time checks but no independent acceptance check.
The next mask must preserve original chromatic paint and actual dark outlines while resolving detached residue. Do not generalize the mask by clearing all gray or black pixels. Full native-candidate,role/context,performance,lifecycle,integration and live-use gates remain open.
