Client Skill Init Idempotency

Client Skill Init Idempotency

Status

client-skill-init-idempotency is source + maintained Vanilla propagated and smoke pending as of 2026-06-02. The patch removes the second Skill_Init.sqf call in client init while preserving the immediate WFBE_SK_FNC_Apply call. The earlier checkout-root blocker was removed by the LoadoutManager root-discovery patch, and propagation now works from this Codex checkout with A2WASP_SKIP_ZIP=1.

• Missions/[55-2hc]warfarev2_073v48co.chernarus/Client/Module/Skill/Skill_Init.sqf

• Vanilla Takistan Client/Init/Init_Client.sqf after LoadoutManager propagation.

What The Code Did

Before the patch, Init_Client.sqf ran Client\Module\Skill\Skill_Init.sqf twice:

Source	Behavior
Client/Init/Init_Client.sqf:547	First Skill_Init.sqf call. This is needed before default gear selection because :551 switches on WFBE_SK_V_Type.
Client/Init/Init_Client.sqf:571-572	Second Skill_Init.sqf call immediately before (player) Call WFBE_SK_FNC_Apply.
Client/Module/Skill/Skill_Init.sqf:10	Compiles WFBE_SK_FNC_Apply.
Client/Module/Skill/Skill_Init.sqf:39-49	Sets WFBE_SK_V_Type and multiplies local WFBE_C_PLAYERS_AI_MAX by 1.5 for Soldier class.
Common/Init/Init_CommonConstants.sqf:249	Default WFBE_C_PLAYERS_AI_MAX is 16.
Client/Functions/Client_PreRespawnHandler.sqf:5	Respawn reapply calls WFBE_SK_FNC_Apply without rerunning Skill_Init.sqf.

Because Skill_Init.sqf:49 has no applied flag or base-value reset, a Soldier client could compound the local AI cap from 16 -> 24 -> 36 during one init path. The likely intended one-time Soldier boost is 16 -> 24.

Patch Shape

The source mission patch removes only the second Skill_Init.sqf call:

• Keep Client/Init/Init_Client.sqf:547 so WFBE_SK_V_Type exists before class-based default gear selection.
• Keep (player) Call WFBE_SK_FNC_Apply in the later skill block so the selected class still gets skill effects/actions before play.
• Do not change Skill_Init.sqf internals, because a single init call is enough for the current path.
• Propagate with Tools/LoadoutManager so Vanilla Takistan matches source.

Changed source files:

• Missions/[55-2hc]warfarev2_073v48co.chernarus/Client/Init/Init_Client.sqf

Propagated maintained Vanilla file:

• Missions_Vanilla/[61-2hc]warfarev2_073v48co.takistan/Client/Init/Init_Client.sqf

Validation

Source/Vanilla validation done:

• Chernarus Init_Client.sqf has exactly one Skill_Init.sqf call and one immediate WFBE_SK_FNC_Apply call.
• Vanilla Takistan has the same single-init shape after the propagation run.
• Skill_Init.sqf still compiles WFBE_SK_FNC_Apply.
• Client_PreRespawnHandler.sqf still applies skill effects on respawn.
• git diff --check passes.
• dotnet run in Tools/LoadoutManager now works from work\a; use A2WASP_SKIP_ZIP=1 for propagation-only runs so missing 7za remains non-blocking.

Pending smoke:

• Local/hosted: join as Soldier and confirm the visible/local AI cap is the one-time boosted value, not the compounded value.
• Local/hosted: join as non-Soldier and confirm normal cap/class behavior.
• Respawn: confirm skill actions/effects are present after death/respawn.
• Dedicated/JIP: confirm no client init regressions in JIP join path.

Modded Mission Note

Modded mission folders also show duplicate Skill_Init.sqf calls in some variants, but those folders are divergent/generated/forked targets and several stale files contain merge-conflict markers. Per repo rules, do not patch modded folders by hand until the generated/forked mission maintenance model is resolved.

Handoff

For Codex/future code owner:

• Keep this as a small client-init cleanup unless future evidence shows another Skill_Init.sqf entrypoint can run more than once.
• If another path must call Skill_Init.sqf, guard only the Soldier AI-cap mutation or store a base cap before applying the 1.5x boost.
• Pair any future modded propagation with the generated mission cleanup work from Tools-And-Build-Workflow, DR-4 and DR-32.

For Claude:

• Good contradiction check: prove whether any UI or respawn path expects cooldown variables from the removed second init call. Current source evidence says respawn uses WFBE_SK_FNC_Apply only.
