 # 02 — Project Architecture
 
-**Status: Draft**
+**Status: Complete**
 
 - **Scope:** Project modules, targets, Build.cs dependencies, plugins (engine + project-local), gameplay-relevant configuration (maps, tags, input, networking, GAS-related settings), engine vs project boundaries.
 - **Inspection method:** Read-only inspection of `.uproject`, Target.cs, Build.cs, module startup, plugin descriptors, `Config/*.ini`, and PluginToolset (`ListEnabledPlugins`, `GetPluginInfo`, `IsEnabled`).
 - **Evidence classifications used:** Observed Implementation, Documented Intent, Inferred, Unknown.
 - **Tool or visibility limitations:** PluginToolset `ListEnabledPlugins` returns the full editor-enabled set (engine + project). No `OnlineSubsystem` / Steam settings found under `Config/` (Pass 4 reconfirmed). Map World Settings GameMode not in asset-registry tags — inferred from package dependencies. SemanticSearch not used.
 - **Last updated:** 2026-07-16
-- **Current phase:** Phase 1 — Static Architecture
-- **Last completed pass:** Pass 4 + Pass 10 (Batch 4D)
-- **Next pass expected to contribute:** Pass 11 when authorized
+- **Current phase:** Phase 1 — Static Architecture (complete)
+- **Last completed pass:** Pass 11 (Batch 5) — status close; static content from Pass 4 + Pass 10
+- **Next pass expected to contribute:** Phase 2E (OSS/runtime config) when authorized

+## Completion notes
+
+Static Phase 1 scope for this document is exhausted. Remaining items (OSS runtime defaults, JoinSession travel, live plugin usage) are **Requires Runtime Inspection** / Manual Editor — tracked in `13-Unknowns-And-RuntimeQuestions.md`.

 - CoreRedirects (GAS* → RIR* rename evidence)
 - **Pass 4:** Per-map GameMode via deps; GameDefaultMap/EditorStartupMap; GI unwired; OnlineSubsystem INI negative inventory; production AdvancedSessions node consumers
 
-### Pending sections
+### Deferred to runtime / Phase 2
 - Confirmation of which other enabled engine plugins are referenced by live gameplay content
 - Runtime OnlineSubsystem default platform when INI keys absent
-
-### Evidence still required
 - Whether JoinSession travels without explicit ClientTravel pin
 - Steam runtime defaults
 
-### Tool or visibility limitations
-- Map World Settings GameMode tags unavailable; dependency inference used
-- Full enabled-plugin list is large
-
-### Unknowns requiring later verification
-- `GI_Dungeoneer` not assigned via `GameInstanceClass` and has 0 referencers — Present but Unconnected
-- GlobalDefaultGameMode absent — per-map overrides only
-- No project OnlineSubsystem INI under `Config/`
