Erosion: "off"|"v1" gate (default off, pending the developer's gate). Output-only: applied to the render map after detail, before the crater carve; the classify path reads pre-erosion heights, so biomes/water stay byte-identical (verified: OFF run bit-identical to the task-14 reference; ON run BIOM/WBID identical to OFF). Governors: droplet count / lifetime / per-cell carve cap (ledger-enforced, thrown on violation). Sea clamp: below-sea cells read-only, land never carved below sea+margin — rendered coastline provably fixed (asserted per generation). Crater excluded at 1.2×R. Deterministic from resolvedSeed+9271 (PCG32). New EROS blueprint section (writer/parser/harness/format doc). Supersedes the reverted D8 approach with the organic droplet model.
