Merge Risk: ⚪ Minimal · up to No actionable issue remains in the reviewed changes. Join relocation and nearest-first grave placement appear mergeable after normal checks. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to A successful rescue can briefly lift a player's movement restriction even when it exists for a reason unrelated to being stuck, including a Discord-link requirement. The restriction is checked again shortly afterward, but the rescue does not preserve its ownership. Retained concerns

- Around line 105-106: Validate the `getHighestBlockAt` fallback in the
join-unstuck flow with `canStand` before teleporting; if it is unsafe, handle
the absence of a safe destination without teleporting the player onto it.
- Line 51: In the JoinUnstuckListener flow, check the result of
player.teleport(target) and return if it fails; only send MOVED_MESSAGE and
write the successful move log after a successful teleport.

A player logged in inside planks someone had built where they logged out and suffocated while the resource pack loaded. On join, anyone whose head is in a suffocating block and who cannot crawl is moved to the nearest safe spot. Graves that cannot go at the death spot now use the nearest free block instead of the first corner of the 5x5 search. Co-Authored-By: Claude Opus 5.5 (1M context) <[email protected]>
A teleport inside PlayerJoinEvent was lost when the client's first position synced (seen on TFMCDev01: logged as moved, still suffocated). Run it on the next tick, which is before the player ticks, and let PlayerManager re-capture the no-character freeze spot after the move.

Why
On 2026-09-26 at 19:48 UTC, Jamjam10626 logged in at 4079, 196, 1663 and died of suffocation 13 seconds later, while their resource pack was still loading. CoreProtect shows that Todik placed planks at 4079,196,1663 and 4079,197,1663 at 09:16 and 09:35 that day. That was after Jamjam logged out at that spot at 02:49, so they logged back in inside a wall.
Their grave was placed at 4077,196,1661. The nearby search checks the (-2,-2) corner first, even though free blocks closer to the death spot were there.
Changes
JoinUnstuckListener(LOWEST priority, so PlayerManager stores its no-character freeze spot after the move). On join it runs the same eye-level test vanilla uses for suffocation. If the player is in a wall and can't fit even crawling, it moves them to the nearest spot with a solid floor and two open blocks (within ±8 blocks), falling back to the top of the column. The player gets a chat message and the move is logged to the console. Creative, spectator and mounted players are skipped.GraveManager.searchNearbynow tries offsets nearest first, so the grave lands next to the death spot.Testing
mvn verify: 255 tests pass locally.CharacterPlaytimeSaveTestwas excluded because it fails on Windows with a file lock, with or without this change.🤖 Generated with Claude Code
