Research Brief Map Selection

Research Task: Map/DLC Selection Logic

Goal: Investigate how TNC decides between Base and DLC Mapspecs when they share the same map name, and determine whether Savegame/Map metadata determines selection before the container mount.

Context: Retail DLCs primarily use chunkid 20/22/24; the custom dlc_4 spec for c02p0 is found. The Canary container is structurally valid, but the final real priority test failed due to the +0x08 Hash Gate or the unexecuted start command.

Scope: Read statically only: all Retail and Probe packagemapspec.json, Savegame game.details/checkpoint_mapstart.dat, Logs, Parser code, and existing Reports. No game starts, no installation changes.

Acceptance Criteria: Clear decision conditions for a single run, including an indication of whether refchunks/layer/basechunkid or Savegame data influences priority. Report exclusively to re_probes/agent_reports/map_selection.md.
