tournament(participants, auto_advance = TRUE) creates a
live tournament runtime ready for result entry.spec() creates a reusable blueprint without
participants; materialize it with
build(spec, participants).validate(spec, n) runs a preflight feasibility check
before building.Pipe stage types onto tournament() or
spec() to define the competition structure:
round_robin(id, ...) — round-robin stage; supports
groups = for parallel group play.single_elim(id, ...) — single-elimination bracket.double_elim(id, ...) — double-elimination bracket.swiss(id, ...) — Swiss-system stage.two_leg(id, ...) — two-leg knockout stage.group_stage_knockout(id, ...) — combined group stage
and knockout.Each verb accepts from = previous_stage() (implicit in
linear chains; explicit from = required only when
branching) and take = for routing.
Selectors sit in take = and resolve against the source
stage’s standings at transition time:
top_n(n), bottom_n(n),
slice_range(from, to) — flat ranking cuts.top_per_group(n), bottom_per_group(n),
slice_per_group(from, to) — per-group cuts; require a
grouped source stage.remaining() — participants not yet consumed by a prior
transition.losers() — eliminated participants.filter_by(fn) — custom predicate on the standings data
frame.result(trn, stage, match, score = c(x, y)) enters a
single match result. For best-of series, pass per-game scores as a
longer vector.results(trn, stage, df) batch-enters results from a
data frame with columns match, score1,
score2.auto_advance = FALSE and trigger manually with
advance(trn, stage).teardown(trn, stage) un-materializes a stage and all
downstream dependents, preserving source-stage results.matches(trn, stage, status) — match table, filterable
by stage and status ("pending", "complete",
"all").standings(trn, stage) — standings table for one or all
stages.stage_status(trn) — per-stage overview with columns
stage, status, complete,
total, materialized.winner(trn) — tournament winner, or NA if
incomplete.rankings(trn) — final placement table.routing_log(trn) — transition audit trail.
