  "implementation": [
    "SessionEnv now captures XDG_DATA_HOME and the current platform.",
    "Linux/macOS resolve sessions under an existing $XDG_DATA_HOME/omp/sessions or $XDG_DATA_HOME/omp/profiles/<profile>/sessions, flattening the legacy agent/ segment.",
    "Windows/other platforms, empty or missing XDG values, and unmigrated app/profile roots retain legacy HOME/USERPROFILE + PI_CONFIG_DIR paths.",
    "Explicit --session-dir remains first; default-profile PI_CODING_AGENT_DIR remains ahead of XDG; named profiles ignore stale agent overrides; OMP_PROFILE remains canonical over PI_PROFILE even when empty, whitespace, or default."
  ],
  "tests_added": [
    "Default-profile XDG resolution and actual session lookup on simulated Linux and macOS.",
    "Named-profile flattened XDG resolution and actual session lookup.",
    "Platform and selected-root existence gates, including base-root-only named-profile fallback.",
    "PI_CODING_AGENT_DIR and explicit --session-dir conflict precedence over existing XDG roots.",
    "OMP_PROFILE empty/whitespace/default suppression of PI_PROFILE, plus PI_PROFILE legacy/default normalization cases."
