Discover the configured Sleeper user's league, roster, and draft for a season.

    A single discovered league is selected automatically. If several exist, this returns
    concise choices without guessing; call it again with league_id. The selected context is
    persisted locally and becomes the default for all league-aware tools.
    

Get the persisted Sleeper user, league, roster, and draft defaults.

Synchronize broad Sleeper league state for setup and season-long operation.

    With weeks omitted, the current NFL week is captured automatically. Pass an explicit list
    for historical/backfill work or an empty list for core state only. Set include_players only
    when the large NFL catalog needs refreshing; Sleeper recommends caching it.
    

Refresh only live draft details, picks, and traded-pick ownership.

    This low-latency path detects picks made during its read. Call it immediately before a
    draft decision, then use the returned sync provenance from get_draft_state.
    

Backfill every week while following Sleeper's previous-league renewal chain.

Get the current local league format, rosters, managers, and sync provenance.

Inspect recent season/draft synchronizations and retained projection failures.

Get draft settings, picks, next-pick context, and an optional roster's local queue.

List active Sleeper players absent from current rosters and this league's draft picks.

This is an availability query, not a ranking or recommendation. Sleeper's search rank only provides stable result ordering until independent valuations exist.

Conflict-safely insert or update one player in the local draft queue.

    Copy expected_queue_revision and expected_state_token from get_draft_state. A stale write is
    rejected so a pick or another queue edit cannot be silently overwritten.
    

Conflict-safely remove one player from an agent-managed local draft queue.
