Canyon River native outlet colour repair

Canyon River V4 (WOG-A-003757) and its named-export alias WOG-A-007873 retain their exact originals, approvals and existing actions. New WOG-A-009255 repairs 879 purple-stained RGB pixels in the finite lower outlet at native 1,024 × 1,536. All original alpha bytes, outside-mask RGBA pixels, cliff strata, needles, waterfalls and healthy foam remain exact; per-pixel luminance changes stay below 0.46. Native complete source/output and light/dark crop pairs were directly reviewed. Grey outlet residue remains; this is a preferred partial repair, with role, topology, relief/contact, scale, desktop/phone Region/Hex, performance, lifecycle and live-world gates open. The local catalog has 9,188 files and the ledger 9,211 records. The initial-review backlog stays 318 from WOG-A-007940; all 75 priority corrections and the complete pending ledger remain in scope. No source admission, world activation, gameplay change or quality waiver is introduced.

The source-specific polygon and colour thresholds correct purple chroma using nearby healthy original water while retaining each target pixel luminance. The grey edge/spray residue is deliberately retained for further inspection. No automatic edge deletion or repeated texture is introduced. The selected bitmap is kept only at its canonical library path; the source PNG is unchanged. Exact SHA-256, dimensions and counts are in canyon-water-chroma-repair.json. Browser measurements and publication status are separate receipts.
