D-258 invariant 2 asks the map to show the minority the orbital summary
suppressed — clearings, marsh, rock, scrub inside a cell that reads "forest" from
space. composition.rs goes to real trouble to invent it, and the conservation
harness measures it: over a District patch on Ferrath the tally is {Barren: 175,
Forest: 16209}, so 1.07% of that ground is exposed rock.
The renderer was averaging it back out. One test, `veg >= Scrub`, at one density
and one strength: Forest, Scrub and both Riparian classes drew the IDENTICAL
mark, and Barren drew none at all. A wood looked like scrub, and bare rock was
invisible by construction — on the rungs whose whole purpose is to show what the
summary hid.
Each class now has its own grammar, differing on the three axes a mark has:
density (how much of the class's ground carries it), strength (how far it moves
the base colour), and lattice (the block size marks are decided on — bigger reads
as a clump, smaller as grain). Rock LIGHTENS where everything else darkens, which
is the point rather than a flourish: bare stone catching the light is the one
cover type brighter than the ground around it, so it separates from vegetation by
sign alone and can never read as "denser plants". It gets its own ScatterField
salt so an outcrop does not preferentially land where a copse already did.
Tuned against captures, not guessed. A first pass gave Forest a 4x4 lattice at
52% density, which produced visibly axis-aligned dark SQUARES — a 4-cell block is
8 screen px at District — and read as an artefact laid over the hillshade. It
also mistook the background for a feature: Forest is 98.9% of this frame, so
marking half of it dark is not "the occasional copse", it is a second colour
layer. Pulled back to grain at a 2x2 lattice, and the occasional thing is now the
thing that catches the eye: the outcrops read as scattered pale clusters of
exposed ground, exactly the "occasional copse/tree/rocky outcropping" that was
missing.
District holds its form through the change (lum p1-p99 74.15, against 74.43
before the cover marks and 13.72 when the rung was flat).

# Version scheme: 0.{phase}.{n} — phase = active Development Cascade phase (D-166).
|
|
# Phase 4 (deterministic world generation) is active.
|
|
# 0.4.1-tagged step canvases carried lake_margin_q's flat absolute-ceiling
|
|
# semantics (pre-per-basin-normalization) and were written to real disk
|
|
# caches during T-1188 eyeball runs — 0.4.2 forces those entries to miss.
|
|
# 0.4.2-tagged Global/Region-rung step canvases sampled the coastline
|
|
# position raw (no coast_warp_px) — T-1160 applies the warp at orbital
|
|
# sampling, changing orbital-rung canvas bytes (elev_q/temperature_dc/
|
|
# moisture_q shift near coasts) — 0.4.3 forces those cached entries to miss.
|
|
# 0.4.3-tagged canvases predate the D-255 extent inversion (a rung now fixes
|
|
# the canvas EXTENT and the gridunit spacing falls out, rather than the
|
|
# reverse). District/Quarter/Block/Chunk kept the same 960x540 cell counts
|
|
# through that change, so their cache keys are byte-identical while a District
|
|
# canvas now covers 3.6 km of ground instead of 1,966 km — a warm cache would
|
|
# silently serve pre-inversion canvases. 0.4.4 forces those entries to miss.
|
|
# 0.4.4-tagged GLOBAL canvases are all 2x1 — `serve_step_canvas_request` was
|
|
# still zeroing Global's wire extent (a pre-extent-inversion sentinel), so
|
|
# every Global request resolved to a two-cell canvas regardless of viewport.
|
|
# Those entries were also cached under a key that ignored extent, so they
|
|
# answered every later request forever. 0.4.5 forces them to miss.
|
|
# 0.4.5-tagged canvases carry pre-T-1237 river courses: one course per D8 HOP
|
|
# rather than one per river (build_paths walks whole headwater->mouth rivers
|
|
# now). The hop-shaped entries survived that fix because it changed only server
|
|
# and client code, never this version — so Ferrath Global replayed 375 fragments
|
|
# with a 106 km longest run, all of them below D-261's read-as-a-line floor, and
|
|
# drew NOTHING, while a cold cache on the same build produced 73 whole rivers
|
|
# with a 1,644 km trunk and drew 18. Diagnosed as T-1239. 0.4.6 forces them to
|
|
# miss.
|
|
#
|
|
# THE PATTERN, now four bumps deep: a change to how a canvas is GENERATED is
|
|
# only half the change — the other half is this line. Nothing enforces the
|
|
# pairing, so a canvas-generation commit that leaves this version alone ships a
|
|
# silent regression that reproduces only on machines with a warm cache. The
|
|
# capture harness no longer hides it (tests/run-visual isolates user:// per run,
|
|
# T-1239), but a real player's cache is still governed by this number alone.
|
|
# 0.4.7 carries NO canvas-generation change — it is the gate that enforces the
|
|
# pairing described above, arriving (T-1242). tooling/canvas_sources.py lists the
|
|
# paths, tooling/check-canvas-version rejects a push that touches them without
|
|
# moving this line, and the registry includes ITSELF so that narrowing it and
|
|
# changing a canvas file in one push still demands a bump. That self-inclusion is
|
|
# why this bump exists: adding the registry trips its own rule. The version is
|
|
# spent rather than special-cased, because "this change is obviously harmless" is
|
|
# the reasoning that produced all five regressions above.
|
|
# 0.4.8 also carries NO canvas-generation change: a test-only edit to
|
|
# composition.rs (its conservation assertion was a tautology) tripped the T-1242
|
|
# gate, because that gate is path-based and cannot tell test code from generator
|
|
# code. Second no-op bump in two days — the false-positive rate is real, and is
|
|
# the price of the ruling that a false negative costs a week. Revisit if it
|
|
# becomes noise; do NOT add an override to dodge it.
|
|
# 0.4.9 is a REQUIRED bump, not a gate formality (T-1213). The disk cache stores
|
|
# the DECODED canvas, and the decode was silently dropping the `relief_q` plane —
|
|
# so every 0.4.8-and-earlier entry physically lacks the field, and would keep
|
|
# rendering the deep rungs as a flat wash even against a build that reads it.
|
|
# This is the first bump in the series where a warm cache is wrong about CONTENT
|
|
# rather than merely stale.
|
|
# 0.4.10 changes how a canvas is PAINTED, not how it is derived, so cached
|
|
# entries are still valid content — but the client step_canvas cluster is in the
|
|
# T-1242 registry and the rule is bump-when-touched, so it moves. Cheap: one
|
|
# round of misses against a map that now reads as terrain.
|
|
# 0.4.11 — per-class cover marks (copse, thicket, rocky outcrop). Paint again,
|
|
# not derivation; bumped because the client step_canvas cluster is in the T-1242
|
|
# registry.
