Everything else from the pair session was either shipped or ticketed with its
rationale in git. These two were design decisions Jeroen made, living only in
a scratchpad under /tmp, one cleanup away from gone.
D-259 — ENCLOSED SETTLEMENTS. Open-air requires atmosphere == standard;
everything else is enclosed, as point locations on the Atlas with interiors
deferred to a separate generator and handled like embedded stations. Branch on
an explicit `enclosed` property rather than the atmosphere string, so enclosed
settlements on breathable worlds (hostile-biome posts, undersea, arcologies)
need no second code path. NULL defaults to enclosed, which fails safe.
The load-bearing claim is that D-220's density model is PHYSICALLY
INAPPLICABLE to a pressure vessel, not mistuned: it measures people per km2 of
footprint driven by utility cost per metre of street, so run airless it yields
1,500 ppl/km2 of open-air streets in vacuum. The handoff mechanism was already
planned — D-166's door boundary contract, where a dome's airlock IS that door.
Atmosphere keeps its full range for the surface-expedition layer; the binary
collapse applies to settlement layout only, and the record says so to stop the
collapse being read as atmosphere not mattering.
D-260 — GENERATOR SCOPE. Sol is encoded as Authored { deepest_rung: Global }
rather than excluded by convention. The DLC gate is a DEPTH, not a boolean, so
a Sol expansion changes one value instead of unpicking an exclusion. No new
wire status: "viewable at Global, no deeper" IS the existing rung-liveness
path. Sol art is an authored data canvas, not a finished image, so it rides
the existing wire and is drawn by the same map-art function as all 269
procedural bodies.
The hazard that made encoding necessary is recorded: systems.db still carries
terrain_reference rows for Sol bodies pointing at heightmaps deliberately never
baked, so a real Earth DEM dropped at that exact path would silently start
generating a procedural homeworld. The importer comment said Sol was excluded;
nothing enforced it.
Also files the last three parked items, which were likewise /tmp-only:
T-1233 tiled/interlaced map loading (workshop-sized D-255 revision, blocked in
spirit on the rung-0.5 cost numbers), T-1234 enumerate the flow tweaks the
fetch panel exposed but which were never written down, T-1235 zoom
discoverability — the person who specified wheel-only zoom could not find it.
T-1231 closed.
