Changes: Bedrock protocol and player state
Layer / File(s)
Summary
Game-mode forwarding and refresh patches/viabedrock/upstreamable/0007-forward-local-game-mode-updates.patch, patches/viabedrock/upstreamable/0007-forward-local-game-mode-updates.pr.md
Local player-list refreshes use the local actor’s current mode. Remote profiles use cached modes with the world default as fallback. Packet tests and validation notes cover these cases.
Score removal and prediction event coverage patches/viabedrock/upstreamable/0026-remove-score-ids-across-objectives.patch, patches/viabedrock/upstreamable/0092-retain-completed-client-prediction-frames.patch
Score removals now target the named objective or all objectives. Prediction tests check mode-event payload negotiation and frame pairing.
Skin and player-profile updates docs/skin-flow.md, patches/viabedrock/upstreamable/0047-encode-current-bedrock-skin-packets.patch, patches/viafabricplus-bedrock/upstreamable/0002-native-entities-and-skins.patch, patches/viafabricplus-bedrock/upstreamable/0002-native-entities-and-skins.pr.md
The skin-flow guide adds a validation link. Native rendering connections refresh player profiles after list updates; the validation notes describe protocol replay checks.
Local physics replay

Local mode handling during physics replay patches/viafabricplus-bedrock/upstreamable/0025-send-completed-local-physics-to-viabedrock.patch, patches/viafabricplus-bedrock/upstreamable/0025-send-completed-local-physics-to-viabedrock.pr.md
Replay mode queries use recorded modes for the local player and live modes for remote players. Bedrock mode changes skip Java’s vertical-motion reset. Tests and validation notes cover these behaviors.
Native UI and rendering
Layer / File(s)
Summary
Native UI and authored presentations patches/viabedrock/upstreamable/0095-integrate-authored-native-ui-presentation.patch, patches/viafabricplus-bedrock/upstreamable/0029-present-authored-native-containers.patch, patches/viafabricplus-bedrock/upstreamable/0029-share-native-ui-scene-rendering.patch
Patch metadata and configuration references change for native UI presentation, containers, and shared scene rendering.
Native world rendering and block appearance patches/viafabricplus-bedrock/upstreamable/0030-use-supported-native-world-actor-definitions.patch, patches/viafabricplus-bedrock/upstreamable/0026-apply-native-fence-geometry-in-bedrock-sessions.patch, patches/viafabricplus-bedrock/upstreamable/0040-preserve-native-occlusion-with-moreculling.patch
Patch metadata or mixin configuration references change for native world actors, fence geometry, and block occlusion.

Merge Risk: Low · up to 40528
The patch series is largely safe to merge. Add the missing PR description sidecar for the remote-player-location patch, and make the game-mode patch's skin test fixture match the skin data shape available at that point in the series, so each patch applies and tests cleanly on its own.

Full details: Title check
Explanation
The title "chore: continue compatibility maintenance" is generic and does not name any specific change. The changeset covers many Bedrock compatibility patches, and the PR objectives describe three specific changes: refreshing cached Bedrock player modes after Java profile replacement, using the local player's game mode during physics replay, and preserving falling motion on spectator entry. The title does not mention any of them. The title is vague and uses non-descriptive wording, so the check is inconclusive.
Resolution
Replace the title with a specific summary of the main change. For example: "fix: refresh Bedrock player game modes after profile replacement" or a title that names the primary change, such as local game mode handling during physics replay.

Keep local profile modes from the authoritative actor when PlayerList
recreates a Java profile. Refresh Bedrock entities' cached PlayerInfo so
their mode predicates agree with the movement controller after replacement.
Fold both fixes into their owning patches and refresh dependent context.
Validate with a failing-before packet regression, full builds, complete
direct/proxy replays, and cold application of all four stacks.
Keep local player game-mode predicates aligned with the controller's replay
state. Java 26.3 reads them from a live profile that can have a later mode.
Limit the override to the local player and the active replay scope.
Fold the fix into the owning physics patch. Cover local ownership, remote
fallback and scope cleanup in a regression, and check installed direct and
proxy clients with the same bounded historical-query matrix.
Suppress Java's unconditional vertical-motion reset for Bedrock mode updates. Keep the native small-motion boundary in BedrockPlayerModes.
Validated with a full add-on build, fresh replay of all four patch stacks, and native/direct/proxy walking and falling controls. Exact trajectories and transition timing remain unverified.

- Around line 468-469: Shorten the `SkinData` fixture in the
`BedrockTypes.SKIN.write` call to match the 19-component record shape available
at the `0007` patch state by removing the two trailing empty-string arguments.
Ensure the later `0047` patch restores those arguments when it adds
`trustedSkinFlag` and `profileHash`.

Shorten the 0007 skin fixture to the pre-0047 SkinData shape.
0007 precedes 0047 in the same upstreamable section. Before 0047, SkinData has 19 components. The fixture passes 21 arguments, so this test source does not compile at the 0007 state. The final stack state is not affected. Only 0047 adds trustedSkinFlag and profileHash.
Pass the 19 components that exist at this point. 0047 must then restore the two trailing "" arguments in this fixture when it changes the record.

Add the required .pr.md sidecar.
This patch is under upstreamable/, but the reviewed revision has no sibling 0013-translate-remote-player-locations.pr.md. Add a non-empty sidecar with the patch purpose, design constraints, validation, and remaining limits before creating or updating the upstream PR. ()
Based on learnings: upstreamable patches require a same-named, non-empty .pr.md sidecar. As per coding guidelines, keep that sidecar focused on purpose, design constraints, validation, and remaining limits.

Validated with full builds, fresh stack replay, and native/direct/proxy controls. Exact trajectories and transition timing remain unverified.
