+## 2026-10-29: t96 wake new-world lakes and keep trees off their banks (Codex)
+
+- Wake water after startup reset; omit whole tree candidates on wet/water-connected low banks.
+  Original mat+temp hashes match for seeds 7/42/424242; pinned settling, physics and save format unchanged.
+- Files: src/sim/worldgen.js, test/t_lakes.js, docs/{DESIGN,TESTING,PROJECT_MAP}.md, tasks/t96* and this log.
+- Tests failed first; all 38 headless suites pass (23 lake checks; /tmp/t96-headless.log).
+  Only browser test: /tmp/playwright-test-t96.py (fresh/reloaded seed 7, pixel, two helpers, no page errors;
+  /tmp/t96-browser-final.log). Inspected shots/t96-{fresh,fresh-settled,reloaded-settled}.png.
+  Sandbox graphics startup stalled; outside-sandbox run passed. No full browser suite.
+- Lake moves on tick 1; levels within two grains by 6,000 ticks (100 seconds). Later snowmelt
+  can flood other trees; that behavior is unchanged. Owner playtest pending. No commit.
