Manifest version: v3-tenant-mode-pak-chunking.v1

This gate locks the UE mobile install policy from §67.1: pak files are chunked by tenant and mode Game Feature Plugin, the base shell plus the selected Tara tenant install first, and the Lilith Commons and Saraswati Stage tenants stream from signed CDN manifests on demand.

Install-First Set#

The Tara mobile install contains exactly these install-first chunks:

Chunk Game Feature Plugin Delivery
pakchunk0-base-shell V3Core install-first
pakchunk20-tenant-tara-studio V3Tenant_TaraStudio install-first
pakchunk21-mode-tara-live-class V3Mode_TaraLiveClass install-first
pakchunk22-mode-tara-on-demand V3Mode_TaraOnDemand install-first
pakchunk23-mode-tara-private V3Mode_TaraPrivate install-first
pakchunk24-mode-tara-cohort V3Mode_TaraCohort install-first

Projected install sizes (hand-authored from the chunk manifest, not measured — no real-device cook has run, per V3/VERIFICATION_AUDIT_2026-05-31.md §67; real-device measurement pending). These figures cover only the base-shell + Tara install-first chunk subset above; the full projected first-launch payload (adding the Commons Atrium and Tier-2 avatar gallery content) is 2.31 GB iOS / 2.37 GB Android — see V3/MOBILE_ON_DEMAND_ASSET_STREAMING.md. The 2.5 GB install budget is normative:

Platform Package Base shell + Tara Budget Headroom
iOS / iPadOS iOS IPA + Iostore paks 1.98 GB 2.5 GB 0.52 GB
Android Android App Bundle + Play Asset Delivery 2.05 GB 2.5 GB 0.45 GB

Streamed Tenants#

V3Tenant_LilithCommons, V3Tenant_SaraswatiStage, and all of their mode Game Feature Plugins are stream-on-demand. Each streamed chunk declares a signed HTTP/3 CDN manifest URL and a SHA-256 integrity value. The release gate fails if any non-selected tenant is marked install-first for the Tara mobile package.

UE Packaging Contract#

The mobile cook profiles point at V3/ue/Build/Chunking/tenant-mode-pak-chunking.json. DefaultGame.ini enables chunk generation, hard-reference-only chunk assignment, and HTTP chunk install data with v3-tenant-mode-pak-chunking.v1 as the chunk install data version.

The verifier is pnpm verify:v3 tenant-mode-chunking. It checks the UE config, asset presets, cook profiles, plugin descriptors, chunk manifest, analytics manifest, tests, and TODO lock. The gate fails closed for budget overruns, missing tenant/mode chunks, non-selected tenant install-first leakage, or streamed chunks without CDN integrity.
