Add --name/--sport filters to the QP backfill script

The reported bug was scoped to Wimbledon, and men's/women's majors share the
same tournament name ("Wimbledon") with gender only distinguished by the
sport, so a name-only filter can't isolate one gender. Add --sport (matched
against the sport's name, e.g. "Tennis - Men") alongside --name, and log the
sport name per tournament in --dry output so the target is easy to verify
before running for real.

-/**
- * Bracket geometry, derived from the real feeder graph.
- *
- * The renderer used to place cards by index within a round — match i at
- * `i * (height / roundSize)` — and drew connectors assuming matches 2k and 2k+1 feed
- * match k. That holds only when each round is an exact halving of the previous one.
- *
- * The LLWS winners bracket is not a halving: two of the four Opening Round games skip
- * Winners Round 2 entirely and go straight to the semifinals (see LLWS_ADVANCEMENT).
- * Under index math those games get pulled to the bottom of column one with nothing
- * above them in column two, and the connectors confidently join the wrong pairs.
- *
- * So lay out from the graph instead:
- *   column = depth from the group's final, counted backwards
- *   vertical order = the parent's slot order (participant1 above participant2)
- *   connectors = actual feeder edges
- *
- * Counting columns back from the final is what makes a printed bracket line up: a team
- * entering late sits in the column where it actually plays, not the column its round
- * name suggests. For the LLWS International side this reproduces the official bracket
- * exactly, including putting the Australia/Mexico game alongside Winners Round 2.
- *
- * Pure — no React, no DB — so the geometry can be asserted against the printed bracket
- * in tests.

-/**
- * Little League Baseball World Series (20 teams, 2025+ double-elimination format)
- *
- * Two independent 10-team double-elimination brackets — United States and
- * International — each producing a side champion, then a World Championship game and
- * a Consolation Third Place game between the two side runners-up.
- *
- * Rounds are shared across both sides: U.S. matches take the low match numbers and
- * International the high ones (see llwsMatchNumber). The phases/groups config splits
- * them back apart for display.
- *
- * A loss in the winners bracket is NOT an elimination — it drops the team into the
- * elimination bracket at a specific slot (see advanceLLWSWinner in models/playoff-match).
- * A loss in the elimination bracket is final.
- *
- * There is deliberately NO "if necessary" game: the winners-bracket champion is out if
- * it loses the Bracket Championship, dropping to the Consolation game rather than
- * forcing a rematch. This is the official LLWS modified double-elimination format.
- *
- * Placement tiers (only 8 teams score — the field is exactly 8 when Elim R4 begins):
- *   1st / 2nd  World Championship
- *   3rd / 4th  Consolation Third Place (real game, so positions are distinct)
- *   5th / 6th  Elimination Final losers
- *   7th / 8th  Elimination Round 4 losers
- *   0 pts      the 12 teams eliminated in Elimination Rounds 1–3
- *
- * Participant array layout (20 slots):
- *   [0–7]   U.S. Opening Round teams, two per game (M1..M4)
- *   [8, 9]  U.S. bye teams, entering Winners Round 2 M1 / M2 at participant1
- *   [10–17] International Opening Round teams, two per game (M5..M8)
- *   [18,19] International bye teams, entering Winners Round 2 M3 / M4 at participant1

- * Resolve which bracket template a sports season's placements should be scored against.
- *
- * A sports season can own several scoring events — a bracket plus schedule events, or a
- * re-created bracket alongside a stale one — and only some of them carry a
- * bracketTemplateId. Picking an arbitrary row is not harmless: calculateBracketPoints
- * falls back to the standard single 5th–8th tier when the template id is null, which
- * silently collapses the two-tier templates (llws_20, afl_10) so a team locked into
- * 5th–6th and one locked into 7th–8th both score the flat 5–8 average. The 3rd/4th
- * distinction that llws_20 and fifa_48 have goes the same way.
- *
- * So: only events that actually carry a template are considered, most recent first —
- * matching the "a re-created event wins over a stale one" rule the LLWS simulator uses
- * when it picks its bracket event.
- *
- * Every requested season gets an entry, null when it has no bracket event, so callers

  * Monte Carlo simulation of the AFL regular season and finals for 2026.
  *
- * Two modes:
- *   1. Pre-bracket mode: no afl_10 bracket exists yet, or it carries no seeds. The ladder is
- *      re-projected from Elo every iteration and its top 10 are seeded 1-10, so the draw is
- *      modelled as still uncertain.
- *   2. Bracket-aware mode: a seeded afl_10 bracket exists. Its slots are the seeding, fixed
- *      across every iteration, and games already played are replayed from their recorded
- *      result instead of being re-simulated.
- *
- * Bracket-aware mode is what makes a banked floor hold. afl_10 is the only template that
- * awards points on seeding alone (entryFloor: seeds 1-4 bank 5th, seeds 5-6 bank 7th), and a
- * simulator that re-draws the ladder every iteration puts those teams back in the Wildcard
- * Round — or out of the finals entirely — where they score 0, pulling EV below points the
- * league has already paid out. Reading the real draw removes that by construction: a team
- * seeded into an Elimination Final is in that game in 100% of iterations, so its worst
- * outcome is the 7th-8th tier.
- *
  * Algorithm:
  *   1. Load all participants for the sports season from DB
  *   2. Load Elo ratings from participantExpectedValues.sourceElo (admin-maintained)

  *   3. Load current regular season standings (wins, gamesPlayed) — if available
- *   4. Load the afl_10 bracket, if one has been generated, for its draw and results so far
- *   5. For each simulation:
- *      a. Pre-bracket mode only: for each team, simulate remaining regular season games

 /**
  * Little League World Series (LLWS) Bracket Simulator
  *
- * Monte Carlo simulation of the LLWS (20-team double-elimination format, 2025+).
- *
- * The tournament is two independent 10-team double-elimination brackets — United
- * States and International — each producing a side champion, then a World
- * Championship game and a Consolation game between the side runners-up. There is no
- * pool play. This mirrors the llws_20 bracket template so simulated placements line
- * up with the bracket admins actually score.
- *
- * Two modes:
- *   1. Pre-bracket mode: no llws_20 bracket exists yet (or it has no participants
- *      seeded). Each side is shuffled into the 10 bracket slots every iteration, so
- *      the draw is modelled as random.
- *   2. Bracket-aware mode: a seeded llws_20 bracket exists. Teams sit in their real
- *      slots and completed match results are honored rather than re-simulated, so a
- *      team that has already lost carries that loss into every iteration.
+ * Monte Carlo simulation of the LLWS (20-team format, 2022–present).
  *
  * Algorithm:
  *   1. Load all 20 participants for the sports season from DB
- *   2. Load the llws_20 playoff bracket, if one exists, to get the real draw and
- *      whatever results have been recorded so far
- *   3. Load championship futures odds from participantExpectedValues.sourceOdds
+ *      (must be exactly 10 US + 10 International, identified by externalId)
+ *   2. Load championship futures odds from participantExpectedValues.sourceOdds
  *      (entered via Admin → Futures Odds; American format)
- *   4. Convert those futures to Elo via the shared probability engine, then drive
- *      each game with the Elo win probability (see "Why Elo" below)
+ *   3. Convert odds to normalized championship probabilities (vig removed).
+ *      These drive per-game win probability: p1 / (p1 + p2). Falls back to 50/50.
+ *   4. Determine pool assignment mode from externalId:
+ *      - Fixed pools: externalId is "US:A", "US:B", "Intl:A", or "Intl:B"
+ *        → use these exact pool assignments every simulation.
+ *      - Randomized pools: externalId is "US" or "Intl" only
+ *        → randomly shuffle each side into Pool A / Pool B each simulation.
  *   5. Per simulation:
- *      a. Place each side's 10 teams into the bracket slots (real draw when known,
- *         otherwise shuffled)
- *      b. Simulate the 10-team double-elimination bracket for each side, replaying
- *         completed games from their recorded result (see simulateSideBracket)
- *      c. Consolation game: US side loser vs Intl side loser → 3rd / 4th
- *      d. World Championship: US champion vs Intl champion → 1st / 2nd
- *   6. Track placement counts across all simulations
- *   7. Convert counts to probability distributions
+ *      a. Assign pools (fixed or random)
+ *      b. Simulate pool play round-robin within each pool (10 games/pool)
+ *         Top 2 by W-L record advance. Ties broken randomly.
+ *      c. Simulate 4-team double-elimination bracket per side:
+ *           G1: A1 vs B2  (WB)
+ *           G2: B1 vs A2  (WB)
+ *           G3: G1W vs G2W  (WB Final)
+ *           G4: G1L vs G2L  (LB R1 — loser eliminated)
+ *           G5: G3L vs G4W  (LB Final — loser eliminated)
+ *           G6: G3W vs G5W  (Side Championship — loser eliminated)
+ *      d. Consolation game: US loser vs Intl loser → 3rd / 4th
+ *      e. World Series: US champion vs Intl champion → 1st / 2nd
+ *   6. Track placement counts across all simulations.
+ *   7. Convert counts to probability distributions.
  *
- * Why Elo rather than raw futures:
- *   A championship future already bakes in the ~6 wins needed to lift the trophy, so
- *   using it directly as a single-game strength (p1 / (p1 + p2)) makes every
- *   individual game as lopsided as the whole tournament and compounds the favorite's
- *   edge over and over. buildLLWSElos undoes that compression first (the empirically
- *   calibrated cube-root step in decompressProbability) before mapping to an Elo
- *   scale, and LLWS_PARITY_FACTOR then widens the Elo curve to reflect how much
- *   single-game variance there is in six-inning Little League baseball. Unlike the
- *   shared convertFuturesToElo helper, the mapping preserves how spread out the board
- *   actually is — see buildLLWSElos for why that matters.
+ * Pool assignment (externalId format):
+ *   "US:A" / "US:B" / "Intl:A" / "Intl:B" → fixed pools (post-draw mode)
+ *   "US" / "Intl"                           → randomized pools (pre-draw mode)
+ *   Mixed: if ANY US or Intl team has a pool suffix, ALL teams on that side must
+ *   have one (throws otherwise). Sides can differ — US fixed while Intl randomized.
  *
- * Side assignment (externalId): "US" or "Intl". The legacy pool suffixes
- * ("US:A", "US:B", "Intl:A", "Intl:B") are still accepted and read as the side
- * alone, so seasons configured for the old pool-play format keep working — pools
- * no longer exist, so the suffix has no effect. When a seeded bracket exists the
- * bracket's own slots decide the sides and externalId is not consulted.
- *
- * Placement tiers → SimulationProbabilities mapping (matches llws_20's scoring):
- *   probFirst            = World Championship winner   (1 per sim)
- *   probSecond           = World Championship loser    (1 per sim)
- *   probThird            = Consolation winner          (1 per sim)
- *   probFourth           = Consolation loser           (1 per sim)
- *   probFifth/probSixth  = Elimination Final losers    (2 per sim — 1 per side)
- *   probSeventh/probEighth = Elimination Round 4 losers (2 per sim — 1 per side)
- *   Everyone else        → all 0 (12 teams out in Elimination Rounds 1–3)
+ * Placement tiers → SimulationProbabilities mapping:
+ *   probFirst              = World Series Champion (1 per sim)
+ *   probSecond             = World Series Runner-up (1 per sim)
+ *   probThird              = Consolation game winner / 3rd place (1 per sim)
+ *   probFourth             = Consolation game loser / 4th place (1 per sim)
+ *   probFifth–probEighth   = Double-elim bracket losers before side championships
+ *                            (4 per sim — split evenly: 2 US + 2 Intl)
+ *   Pool play losers       → all 0 (12 teams, did not advance from pool play)
  *
  * Admin setup:
  *   1. Create a Sport with simulatorType = "llws_bracket"
  *   2. Create a Sports Season and add exactly 20 participants (10 US, 10 International)
- *   3. Set externalId on each participant via Admin → Manage Participants to "US" or
- *      "Intl" (optional — names starting with "US " infer US, all others infer Intl).
- *      Once the bracket is generated and seeded this is no longer used.
+ *   3. Set externalId on each participant via Admin → Manage Participants (optional if names follow the convention):
+ *      Pre-draw:  "US" or "Intl"  (or leave null — names starting with "US " infer US, all others infer Intl)
+ *      Post-draw: "US:A", "US:B", "Intl:A", or "Intl:B"
  *   4. Enter championship futures odds via Admin → Futures Odds (sourceOdds)
  *   5. Run simulation via Admin → Simulate

 ## Input Policies
 
-Direct ratings are preferred by default. If a simulator declares derived inputs, readiness may also pass with those alternatives:
+Direct ratings are always preferred. If a simulator declares derived inputs, readiness may also pass with those alternatives:
 
 - `projectedWins` can become Elo using `seasonGames` and `parityFactor` from season config.
 - `projectedTablePoints` can become Elo using `seasonGames`, `maxTablePoints`, and `parityFactor`.
 - `sourceOdds` can become Elo through the shared futures-to-Elo conversion.
 - `sourceOdds` can become a generic `rating` when the simulator declares `derivableInputs: { rating: ["sourceOdds"] }`.
 
-### Raw Elo vs. projections
-
-Raw Elo and projections are *substitutes*, not a blend: `inputPolicy.baseEloPriority`
-lists them in order and the first source a participant has wins outright. The
-default is `["sourceElo", "projectedWins", "projectedTablePoints"]`, so a stored Elo
-beats a projection. Set the Base Elo Source control on the simulator page (or
-`baseEloPriority` directly) to `["projectedWins", "sourceElo"]` when projections are
-the season's source of truth. Futures odds are separate — they blend on top of
-whichever base won, weighted by `inputPolicy.oddsWeight`.
-
-Whenever you write a projection without an explicit Elo, stamp
-`metadata.sourceEloMethod` (`"projectedWins"` / `"projectedTablePoints"`) on the
-row. `getParticipantSimulatorInputs` reads that flag and returns `sourceElo: null`
-so the Elo is re-derived from the projection on every run. Skip it and the
-non-destructive upsert leaves the previous Elo in place as a *direct* value, which
-then wins the priority race — the projection is stored and silently ignored. Both
-the Elo Ratings page's projections mode and the simulator page's CSV importer do
-this; any new importer must too.
-
-Projections are stored and displayed exactly as entered. Never round-trip one
-through its derived Elo for display: the conversion rounds to an integer Elo, and a
-run re-resolves that Elo through the input policy (clamping, plus any futures
-blend), so the number the admin sees drifts away from the number they typed.
-
-### Mid-season projections
-
-A projected win total is a projected *final* total. A simulator that seeds from
-projections mid-season must spread the difference over the games still to play —
-`(projectedWins - currentWins) / remainingGames` — rather than reusing the
-season-long rate the derived Elo encodes, or it will never reach the projection.
-See `seedingWinRateFor` in `mlb-simulator.ts` (config knob `projectedWinsWeight`,
-1 = the projection is authoritative) and `simulateRegularSeasonSeeds` in
-`nll-simulator.ts` (which additionally decays a preseason prior as the season
-completes).
-
-Two guards belong on any such rest-of-season rate:
-
-- **A target outside `(0, 1)` means the projection is stale** — the team has
-  already met it, or can no longer reach it. Fall back to the Elo rate. Clamping to
-  a floor or ceiling instead simulates a team to stop winning entirely, or to win
-  out, and collapses its seeding variance.
-- **Only apply a projection that actually produced the resolved Elo.** Check
-  `metadata.sourceEloMethod === "projectedWins"` (see `projectionForSeeding` in
-  `mlb-simulator.ts`). Any other method means the Elo represents something else: a
-  hand-entered Elo that won the `baseEloPriority` race, or a futures blend. Seeding
-  off the raw projection in those cases makes the projection simultaneously ignored
-  as the Elo source and authoritative for the standings, and runs seeding and
-  playoff matchups on two different strength scales.
-
 Missing tail participants must remain blocked unless the season config explicitly chooses an `inputPolicy.missingEloStrategy`:
