The 168 horizon-world examples the parity harnesses run become modules of
one example, examples/probe, that dispatches on its first argument;
crate::args() gives each the command line its example saw. Linking ~170
binaries, each instantiating horizon-world's generics again, was most of
the parity job's probe build (review plan, section 1).
The harnesses build `--example probe` and run `probe <name> ...`.
tools/parity.py counts only the probes a harness ran, and the support
modules they name, as its dependencies, so editing one probe still reruns
only its own harnesses (and PARITY_RUST_SCOPE keeps working).
The six manual tools (benches, loot_fill, structure_blocks, vanilla_diff,
attribute_memory, behaviour_load_profile) stay separate examples.

A new harness decorates a 13x13-chunk area around each site, on both sides,
in the order vanilla's chunk scheduler uses around a player standing there
(chunk_dump HORIZON_LIST_ORDER prints decoration_order::vanilla_order), and
compares every block state, quart biome, block entity and scheduled tick:
the two reported spots on seed 1891623539983467248 (taiga trees at
204 -239; a stronghold with sculk and a geode at 4870 401), eleven tree-heavy
biomes and the nearest mineshaft, village, ancient city and trial chambers of
two seeds. 21 sites, 3,549 chunks, 0 differences.

Add version-bound core, world data, geometry, generation and feature implementations with native client/server comparison tools and scoped evidence reports. Apply Horizon project branding.
Workspace tests, Clippy and 147 Python tests passed. Full 51-family survival and expanded provider comparisons are still running; complete gameplay parity and a playable Rust client remain unfinished. Private game artifacts and the isolated simple-block placement work are excluded.
