Borrow the exact prior-completed landscape visibility transaction and S2 CELLARRAY owner for the opt-in IA-24 directional-shadow pack. Select terrain by authored 1..64 cells, ordinary casters by CELLARRAY, and buildings by outdoor EffectCellId with no fallback.
Keep retained caster/material/terrain topology stable across visibility-only frames. Publish exact arbitrary active instance runs and bounded terrain commands through separate selection sequences; preserve transform-journal, fade/retry, deferral, shader/RHI, ordinary world, and pack-off behavior. Amend IA-24 and the S5 ledger.
Pre-commit gates: Release solution build 0 warnings/0 errors; focused visibility/frame/caster/prepared/GPU/terrain/pack lane 137/137; warmed caster/prepared/terrain selectors 0 B; git diff --check clean. Official hermetic and InstalledDat evidence intentionally run post-commit from this exact clean tree.
Mutation evidence (each restored exactly): (1) CELLARRAY->Parent first failed PriorLandscapeSelection expected [201,202,203,205], actual [204,205]. (2) all resident terrain first failed Assert.Single with 3 commands. (3) building EffectCell->anchor first failed expected trailing 205, actual 206. (4) admit missing membership first failed with extra 204. (5) completed->building scratch first failed completed-view Assert.True, expected true/actual false. (6) selection advanced BuildSequence first failed expected 1/actual 2. (7) alternating->prefix first failed active command count expected 3/actual 1.
