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.

Tools/Scripts/README.md: the falloff dials and what they actually do --
including that IslandAxisX is a weak lever because the island is already
Trench-clamped at ~90% of the map width, so nobody re-derives that the hard
way. The spine crest fix, and an explicit note that the spine's AXIS is
still a straight line down the map centre: known, deferred, its own task.
BLUEPRINT_FORMAT.md config-knobs section: the three new dials, each labelled
with whether it moves biomes. CoastProfile does NOT (it cannot move the
waterline, so HGTS changes while BIOM/WBID/WBTB/WSRF stay bit-identical);
IslandAxis* and OffshoreIslandDensity DO, by design.

BLUEPRINT_FORMAT.md: TDTL rewritten for the v2 body (30 B) with the
version-skip rule spelled out -- this is the one section whose body is
VERSIONED rather than extended, because v1's layout was retired rather
than grown, and a reader that guesses would mint plausible nonsense.
Records edgeAmpM as APPLIED (post-clamp), so the file always describes
the terrain rather than the request. Config-knobs section updated:
ShelfEdgeVariation is metres of INPUT height -- a boundary displacement,
not an elevation.
Tools/Scripts/README.md: the two detail passes and why neither can breach
the red ceiling or the 420 m cap (K2/K6 do not move). Adds an explicit
"no rivers, no erosion, no flow routing anywhere in this pipeline" note
with the reverted D8 pass and its lesson on the record, so the next
reader does not re-derive it.

Both sea-level modes documented (flat default 0.15 / legacy field
Lerp); noted the blueprint does not record which model produced it —
the WBTB levels are the observable. Batch runner lives in /tmp
(throwaway), not in-repo.

Byte-accurate entries for the three water sections (transitional
per-body level rule, provisional salinity, WSRF sentinel/quantization),
updated size math (~576 MiB at 8K with water), the on-the-record
rationale for NOT serializing basins, and README updates for the new
pipeline stage, the 0_water snapshot, and the SkipRoads toggle.
