Mechanism confirmed by code inspection: river_cells/mouths are filtered against the RAW 512x256 heightmap sea level (drainage.rs:258-259, elevation[i] >= sea_level), but the drawn ocean is the derived MORPHOLOGY verdict (district_profile.rs:1464-1465 open_water) — which post-T-1162 includes the coast-warp invention (the drawn coastline is deterministically displaced from the heightmap coast) and at Region rung aggregates at 204.8 km cells. Anywhere the two waterlines disagree, a raw-land river dot renders over painted ocean; mouths are worst-case by definition (last land cell on the RAW coast — wherever the drawn coast is displaced inland, mouths render offshore). Long ocean-crossing dot trails = low-lying raw-land chains the derived morphology paints as water. This is the Q-100 dual-artifact class Si''s wave-1 audit pre-flagged. Fix-layer options for Tyre''s ruling: (A) client-side clip against the arrived composite''s per-cell water class (cheap, presentational, keeps two truths but hides disagreement; needs a mouth rule — snap-to-drawn-land vs suppress); (B) server-side reconciliation — classify skeleton cells against the WARPED/derived coast at extraction (one truthful waterline per D-166 honesty; couples drainage to the invention layer, golden + cost implications); (C) fold into T-1170 course invention (courses terminate at the invented coast naturally) and accept the artifact until then.
TYRE RULING (2026-07-23, full text in PR record): option (D) — client-side draw-time clip now, retired into T-1170. Mechanism sizing corrected: WARP_AMPLITUDE_CAP_PX=0.75 (sub-pixel, ~57km max on Lendel) proves the warp is fringe-only — the ocean-crossing trails are Region morphology AGGREGATION painting low raw-land shelves as OpenOcean. Decisive architecture point: the drawn coast is RUNG-INDEXED (warp_fbm''s cutoff admits more octaves at finer rungs — a family of curves, not one), so no single server-side waterline is well-defined; option (B) rejected on well-definedness, not cost. Rules: (1) clip river dots + confluences against the arrived composite''s per-cell morphology water verdict (OpenOcean/Lake) at the rung being painted — strict drop, no snap; (2) Region 205km-cell amputation of final coastal dots accepted (invisible vs the trails it kills); (3) mouths in drawn-water cells SUPPRESSED, never snapped (snapping invents an uncomputed landmark; suppressed mouths return with real geometry in T-1170) — flagged to Jeroen as the one taste call, proceeding on Tyre''s recommendation; (4) basin boundaries NOT clipped (faint watershed overlay, legitimately grazes offshore pour-points — out of scope); (5) dot-pop across rungs is the honest consequence of the rung-indexed coast, not a regression; (6) retirement marker at the clip site, retired in the same change as T-1170''s coast-terminating courses.
