bracketeer 0.1.0

First release.

Tournament construction

• 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.

Stage verbs

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.

Routing selectors

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 entry

• 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 is on by default: when the last match in a stage is entered, all downstream stages materialize automatically. Disable with 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.

Inspection

• 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.
