Pure analysis over the ERODED render map: changes zero terrain, adds zero water. Priority-flood (task-03 family, Barnes heap+pit, 8-connected) with a one-ulp epsilon so every filled pit keeps a strictly descending routing path — the ~16.5k erosion pits route through; depressions >= 2 m deep and >= 10k px survive as terminal basins (70 on the working seed). D8 flow directions on that routing surface (D8 as a COMPUTATION, not the reverted carving use), Kahn-propagated flow accumulation, then promotion: TRUE-ocean outlets (WBID 1 only — two of the first draft's three 'sea-reaching' trunks actually ended in enclosed lagoons, which is exactly the overclaim the gate must not inherit) ranked by drainage area, top ~3 with outlet separation become trunks; max-accumulation stems; mountain-exit from sustained along-stem grade; lean deduped tributaries; lean endorheic terminals credited with per-basin TOTAL inflow (acc at the deepest cell undercounts flat lagoon beds 10x — measured). Output: console report + a JSON plan sidecar next to the source blueprint — deliberately NOT a blueprint section, so the plan cannot masquerade as realized water. The source .dat is never written (md5-verified). Headless tool, ~21 s analysis on 8K; RIVERPLAN_* env dials. Seed 1280587109 findings for the gate: 3 ocean trunks spread west/north/east (436k/409k/325k px); the island's five LARGEST systems (1.1M-2.3M px) are all endorheic — three end in big enclosed lagoons (classify lakes, 19-20 m basins), two in dry pans; 62.9% of land does not drain to the open ocean, the drainage restatement of task 18's 'erosion cannot cut the lowlands'. The 2.27M-px giant terminates in the SE lagoon ~1.1k px from the southernmost town (filed south report, not enforced). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
