 The following Phase 8 slices have local implementation and verification evidence in this document: 8.29 dynamic allocated launch flags and endpoint handling; 8.30 allocator claim/reconciliation; 8.31 signed assignment/roster validation; 8.35 initial-connect no-show and casual bot policy; 8.36 controlled drain and shutdown acknowledgment; 8.39–8.43 client state, assignment, profile, recovery, and idempotent action retry; 8.44 structured observability and content-aware redaction; 8.45 bounded API metrics export plus optional Prometheus scrape/alert rules; 8.46 normal/race/vet/fuzz coverage; and 8.47–8.48 offline testkit coverage. Their remaining acceptance text is infrastructure or production dependent where explicitly noted below the corresponding row.
 
-The following are not locally certifiable from this workspace and remain open prerequisites rather than silently “done”: Valve/GodotSteam credentials and hosted SDR (7.1–7.8), live PostgreSQL/Redis execution where Docker is unavailable, live Agones/kind lifecycle (8.30–8.38, 8.49), public-network chaos/load/cost/release gates (8.50–8.53), and real-hardware graphics profiling (0.15b onward). `TODO.md`’s AI-training and presentation tasks remain separate from multiplayer and are not marked by this index.
