Replace the sun-driven Stefan-Boltzmann temperature with the D-240 class-envelope
model. Temperature derives only from authored fields — no orbit/star physics.
- [planet_class_temperature] envelope table in climate_constants.toml (approved
bands: frozen [-90,-25] .. hot_arid [20,58] .. volcanic [30,90]); cold_/hot_/
warm_ prefix parsing; temperate fallback for unknowns.
- derive_temperature_c(params, constants, body_seed): band = envelope(planet_class);
latitude lerps across it (equator=warm, pole=cold); atmosphere greenhouse +
elevation lapse modulate within; small seed nudge for per-body variety; CLAMP to
band — a body can never escape its class. Airless -> None.
- Delete the dead astrophysics: derive_distance_au, ClimateConstants::luminosity(),
the [star_luminosity] table. Strip orbital_period_days/spectral_class/star_type/
axial_tilt_deg from BodyParams + BodyParamsReader (read 3 cols from bodies, no
star_systems join). DB columns left in place (no regen).
- New every_planet_class_derives_within_its_band test (13 classes x 5 atmo x 19 lat
x 4 seeds, all in band) — the D-240 consistency guard.
Verified on 25 diverse real bodies: the worlds that derived to +356C now sit inside
their class bands (temperate capped at 28C). cargo test passes, clippy -D warnings
clean, fmt clean.

- Hoshe: body_without_system_row test inserted a NULL system_id, impossible
under production schema (system_id NOT NULL REFERENCES star_systems). Rewrite
as body_with_orphan_system_id_* — non-NULL system_id with no matching
star_systems row (the real case the LEFT JOIN guards) + NOT NULL in the test
schema + corrected comment.
- Tyre: cascade.rs PERF/TODO comment said the region path 'defers to T-1032';
T-1032 IS this PR, so production dispatch is now live. Update to track T-1028
only and note the cost is live in production.
No production logic change. cargo test body_params_reader 7 pass, clippy clean.

The D-239 carrier layer (T-1023/1024/1026) only ran in tests because every
production AnalyzeBody enqueue passed body_params: None. Wire the real path:
- New BodyParamsReader (server/src/atlas/body_params_reader.rs): read-only
systems.db reader, joins bodies -> star_systems (LEFT JOIN) for the climate/
tectonic inputs. SQL verified against systems-schema.sql. All fields Option,
NULLs handled; tectonic_activity absent from schema -> None (derives from
planet_class). 5 unit tests.
- layer_proxy.rs: on cache miss, read the body's params and pass
Some(Box::new(..)). On read error, warn + fall back to None (cascade stops at
Settlement, no panic) — graceful degradation.
- plugin.rs / main.rs: register BodyParamsReaderResource (CityContextReader
pattern) and thread it through serve_atlas_requests.
BodyWorldState.regions now populates for real bodies in the D-206 background
pass. End-to-end tests cover wired (regions populated) + unwired (empty) paths.
cargo test 1504 pass, clippy -D warnings clean, fmt clean.
