81 client examples that harnesses run become modules of examples/probe:
harnesses run `probe <name> ...` (or `cargo run --example probe -- <name>`),
and the shared helpers (audio_common, hud_fixture, chat_screen_fixture)
move with them. The benchmarks and manual tools stay standalone examples.

lab.VERSION, lab.GAME (.local/minecraft/<version>) and lab.RESOURCES
(.local/horizon-client/<version>) come from the lock, and lab.version_info()
reads the pinned client jar's version.json. Every harness, generator and
tool that named 26.3 (resource folders, jar and source paths, result
records, the vanilla client's --version and asset index, the bare login
client's protocol, the benchmark's options.txt data version, the packet id
table's header) uses them, so a candidate worktree pinned to another version
runs them unchanged.

Choosing packs in the Resource Packs screen only reloaded the GUI atlas
(and only when it kept its size), item models and languages; block
textures and models changed after a restart, and sounds, clouds and the
world border never did. Block textures were also squeezed to 16x16, and
the pack overlay took every file from the top pack, so a pack's own
en_us.json, sounds.json, font or atlas definition replaced vanilla's
instead of adding to it (all other text, or every vanilla sound, gone).
- Minecraft.reloadResourcePacks: rebuild block sprites and models, mesh
tables, the shared atlas, item models, sounds, languages, GUI
metadata, clouds.png and forcefield.png from the new overlay; swap the
mesher's context (workers read it per job), mesh every loaded section
again (LevelRenderer.allChanged) and build a renderer with the new
textures. Nothing switches if loading fails.
- The block sprite array takes the largest texture's resolution (power
of two, at most 256 MiB), so 32x/64x packs keep their detail;
animations upload at that size.
- Files vanilla reads as resource stacks are merged in the overlay:
ClientLanguage (keys override), SoundManager (sounds add up unless an
event replaces; a sounds.json Gson rejects is skipped whole),
FontManager (top pack's providers first), SpriteSourceList (sources
bottom up). Languages are read from every namespace, not only
minecraft.
- Missing or broken block textures use vanilla's missing texture; packs
that still break startup fall back to the default resources
(Minecraft.rollbackResourcePacks).
- Open Pack Folder opens the folder on macOS and Windows too.
tools/test_resource_pack_parity.py checks pack discovery, overlays,
filters, which pack provides a file and the merged languages, sounds,
fonts and atlases against vanilla's FolderRepositorySource,
MultiPackResourceManager and reload listeners.
