Roam 1.3.0

Added

• Exploration-gated biome unlocks (opt-in, biome-finder.unlock.enabled): /rtp biome — new alias /rtp biomes — only accepts biomes the player has physically discovered. First contact grants an advancement toast, a chat notice and a sound. Staff bypass via roam.biome.bypass-unlock. Existing discoveries are honoured on upgrade.
• Biome collection GUI: undiscovered biomes render as sealed crystal cards that flip to each biome's own icon once explored — 54 curated textured heads bundled, plus a description and a "You'll find:" line for all ~110 shipped biomes, and a Discovered: N/M progress counter. Custom heads via icon: "head:<base64>" in biomes.yml.
• /rtp location <name>: teleport to admin-defined spawn-point presets, gated per-preset with roam.location.<name>.
• Four new languages: Russian, Simplified Chinese, Romanian and German join EN/ES/PT_BR — seven bundled translations covering chat and GUI (gui_<lang>.yml), switched together by language:.

Performance

• Chunk-free candidate screening on Iris worlds: water and biome checks now run against Iris' own noise streams instead of generating a chunk per rejected candidate — the single biggest cost of RTP on custom generators is gone.
• Adaptive mode (on by default): an MSPT probe classifies the server as RELAXED / BUSY / STRESSED — background generation throttles down to zero under load, and search parallelism clamps so /rtp never piles chunk loads onto a struggling tick loop. Each world also learns its own search difficulty and borrows extra parallel candidates only where they pay off.
• Demand-gated location cache: idle worlds stop generating terrain in the background entirely (one bootstrap entry kept); active worlds refill as a slow trickle. With warm-chunks, a cache hit costs a disk read instead of fresh generation — effectively instant /rtp, even on Iris.
• Two-phase chunk preload: teleports block only on the 9 chunks around the player; the outer ring loads in the background after arrival.
• Per-candidate slot timeouts with replacement: one stuck chunk generation no longer freezes the whole search, and late-finishing winners are rescued instead of discarded.
• Cached biome rosters and engine handles: tab-complete and the biome menu no longer walk registries/reflection on every keystroke.

Fixed

• GUI pagination dying after the first page navigation; border/footer clicks could resolve to a real biome; world menu broke with customised item names.
• "Searching..." boss bar stuck on screen after teleporting — full lifecycle rework (kind-tagged bars, exception-safe teleport tail, quit cleanup) plus a self-healing watchdog.
• Search slot timeouts discarding valid locations found moments later on slow hardware.
• Citizens biome NPCs bypassed the biome-finder toggle and the unlock gate.

Changed

• Iris integration flagged experimental: works without server lag, but chunk loading on Iris teleports is still slow. Mitigations documented in the README.
• Unified teleport pipeline (seven entry points over four shared gates) backed by a 21-test suite that gates every build.
• Professional text pass: emojis removed from every player-facing surface (GUI, boss bars, titles, messages in all languages).

Removed

• /rtp structure — out of scope for Roam's design.

No config migration needed — every new key ships with a sensible default.
