Note

Part of native stack #8411 (feature tracking: #8412). Merges bottom-up through the GitHub stacked-PR UI once the type-migration stack (#8398) is in.

Each PR is file-partitioned: every file appears in exactly one PR in its final sharing_tab form, so each PR's diff is byte-identical to that branch. Regenerated deterministically by just bar::sharing-split.

Summary (LLM-generated, claude-opus-4-6)

Wires the sharing policy system into the unsynced UI layer: the advanced players list, top bar, selected-units shader, chat widget, team stats, and unit-share command all now read PolicyResult from the TeamTransfer module instead of using raw Spring.ShareResources calls and a flat sharingTax constant. Share buttons render enabled/disabled per-resource and per-unit PolicyResult fields (canShare, amountSendable), tooltips are generated by TooltipText helpers with full tech-progression and tax-rate context, and hovering a player row highlights invalid units in red via a new g_invalid flag in the DrawPrimitiveAtUnit shader pipeline. A new SharePolicyChanged widget call-in (registered in barwidgets.lua) triggers policy repack and validation invalidation so the UI stays consistent when policies change mid-game (e.g. on tech-up). Column-module definitions are extracted from gui_advplayerslist.lua into a gui_advplayerslist_modules.lua factory, and i18n strings are expanded into base/tech variants covering disabled, taxed, invalid, buildDelay, and stunDelay states.

Superseded by the modules stack: sharing now ships as one de-noised PR — #8463 (modules — multiplayer 2/2: sharing v2), tracked in #8412. Closing this chain; the branch stays for reference.
