Saving creates its counters at 0. `setCounter` takes a whole number from 0 to 1,000,000,000 (`invalid_counter_name`, `invalid_counter_value`); deleting a command keeps its counter.

 - A quick duel (the default, and always the case for StreamElements commands) is rolled at once: turns alternate, challenger first; a d6 per swing gives a crit of 50% maxHp on 6, a hit of 34% on 5, a miss on 3-4 and a defender counter of 34% on 1-2. After 12 rolls more hp wins; equal hp goes to sudden death (the next blow wins). A winner at full hp gets +3 Elo (flawless). The result stays off chat until the stream has shown it: the duel gets `revealAt` = settle time + 2200 ms + 1800 ms per roll + 500 ms + `streamDelayMs` (the channel's stream delay, 6000 by default). Until then the StreamElements reply is only "Fight on: A vs B! Watch the stream for the winner.", and `!elo`, `!ranks`, `/api/leaderboard`, `/api/profile` and `/api/looks` show both fighters' numbers from before the fight (their rank is worked out on those numbers), with full hp and no `respawnAt`; `POST /api/profile` answers with the same masked numbers. Any challenge that involves either fighter answers `result_hidden` ("That fight is still playing on stream."), the same for winner and loser, so a third viewer can't probe who lost; the pair itself gets `rematch_cooldown`. The overlay shows the knockout and the Elo change at the end of the replay (no winner banner); where the PixFray bot reads chat (`chat.bot`), it posts the result line. `/api/state`, the live websocket and the admin snapshot are not masked, because the overlay and mods need them, so anyone who opens the overlay page sees the result before the stream does. The masking keeps chat replies and ranks from spoiling the stream; it does not keep the result secret.

+- Unrated duels: the room asks whether the channel is live (`currentStream`, cached 60 s) before each `!challenge`,
+  `!fight` or `!rematch` and passes the answer as the command's `stream`; game.ts keeps it in `state.stream`

+  ranked again next stream."
 - An active duel with no action for `inactivityMs` is cancelled without scoring. Cancelled duels
   return both players to maxHp.
 - Upgrades (server/upgrades.ts): every win earns one point and check-ins add more (`bonus`), with no cap. Points buy levels in power (damage dealt), guard (damage taken), luck (the chance a quick-duel miss lands as a hit), crit (the chance a hit becomes a crit; in an HP fight, that a strike or heavy deals +50%), dodge (the chance a quick-duel hit or crit on you misses), counter (quick duels: +counter damage, and the chance a foe's miss becomes your counter) and vitality (+4 max hp a level, ceiling +60, in both duel kinds; the duel keeps each fighter's full hp in `duel.maxHp`, heals cap there, a flawless win needs it, and blows stay sized on the channel's base `maxHp`). Levels 1-8 cost 1 point each and give 4% each (counter: 2% damage and 2% chance); the cost doubles every 8 levels (9-16 cost 2, 17-24 cost 4), and above level 8 the effect closes in on a ceiling (power, guard and counter damage 60%, luck, crit, dodge and counter chance 50%; a 4% stat at level 16 gives about 44.2%). A quick-duel swing checks, in order and each with its own roll (`rolls[k * 24 + i]`, slot k: die 0, luck 1, crit 2, dodge 3, counter 4; the room sends 120 rolls): the attacker's luck, the attacker's crit, the defender's dodge, the defender's counter. Stored levels stop at 200. The channel's `maxStatLevel` caps the levels that count in its duels; levels above it stay saved. A rank reset that leaves too few points takes levels off vitality, then counter, dodge, crit, luck, guard and power. Profiles carry `bonus` (check-in points), `checkins` and `streak`; the profile answer's `upgrades` has `points`, `fromWins`, `fromCheckins` and `maxLevel`. The fighter page offers suggested builds (`PRESETS`) that fill the levels from the points; the viewer still saves. Points can be moved while the fighter is not in a duel. Hats are cosmetic; some unlock at a number of wins. A rank reset clears Elo and wins but keeps `bonus`.
-- Dollars: every finished ranked duel pays `winDollars` to the winner and `lossDollars` to the loser, saved fighters only. game.ts records it as `duel.payout` and the room adds it to `profiles.dollars` once, in the same transaction (`duel.paid`). Like Elo, a payout stays out of `!wallet`, `/api/profile` and the leaderboard until the stream has shown the fight. Profiles carry `dollars` (at most 1,000,000). Check-ins give points, not dollars. A rank reset, a profile save and a re-save keep dollars; removing a viewer deletes them.
+- Dollars: every finished ranked duel pays `winDollars` to the winner and `lossDollars` to the loser, saved fighters only (a `pair_cap` duel pays half, other unrated duels nothing). game.ts records it as `duel.payout` and the room adds it to `profiles.dollars` once, in the same transaction (`duel.paid`).

A rank reset, a profile save and a re-save keep dollars; removing a viewer deletes them.
 - `!wallet` (the StreamElements `wallet` action, also while duels are paused): "@x: $N PixFray dollars, P upgrade points, S-stream streak." Reasons: `wallet`, `no_fighter`.
 - Pets and the shop (server/pets.ts): 14 built-in pets in 5 tiers, plus up to 24 uploaded per channel. A fighter owns any number of pets (`owned_items`) and brings one (`profiles.pet`); hats can be bought too. A pet's boost is added after the channel's `maxStatLevel` cap: common and uncommon +1 to one stat, rare +2, epic +2 and +1 to a second stat (those use power, guard or luck), legendary +1 to 4 different stats out of all 7, rolled for each owner at purchase (`owned_items.roll`; legendaries bought before rolls existed get one when the room starts). Each owner may reroll a legendary once for free (`owned_items.rerolled`); the new set always differs, and it's refused while the fighter is in a challenge or duel. Pets cost `petPrice<Tier>` dollars; a hat whose wins aren't reached costs `hatPricePerWin` times the wins it needs. The overlay draws the pet behind its fighter at about 40% of its height; epic and legendary pets sparkle, legendary pets hover. Snapshot players and `/api/looks` carry `pet` and `petTier`; players also carry `petBoost`.
 - Cosmetics and builds (server/cosmetics.ts, drawn by src/served/cosmetics.ts): recolor (a CSS filter on the fighter), pet color (the same 8 tints on the pet), accessories, walking trails, win effects (about 3 s over the winner when the overlay shows the result), win taunts (a speech bubble then) and titles (under the nameplate). Each kind has one config price. Owned cosmetics are `owned_items` rows; the worn ones are profile columns. Build slots: 1 free, the 2nd costs `buildSlotPrice`, the 3rd to 5th `buildSlotPriceMore` each. Each slot keeps its own loadout in the `builds` table; saving to a slot makes it the one on stream, and every build can spend the full point pool. Removing a viewer deletes their builds; a rank reset keeps them.
 - `!pet [@name]` (the `pet` action): "@x's pet: Fox (rare), +2 power." Reasons: `pet`, `no_pet` (with the site link for the sender's own), `no_fighter`.
-- `!stats [@name]` (the `stats` action): "@x: Power 10, Guard 8, Crit 4. 12 points unspent. Pet: +2 power." The levels are those that count in duels (capped by `maxStatLevel`), from shown results only; "no upgrades yet" with none. Reasons: `stats`, `no_fighter`.
+- `!stats [@name]` (the `stats` action): "@x: Power 10, Guard 8, Crit 4. 12 points unspent. Pet: +2 power." The levels are those that count in duels (capped by `maxStatLevel`), from shown results only; "no upgrades yet" with none. With @name and a pair limit, it adds "N ranked duels left between you this stream." Reasons: `stats`, `no_fighter`.
 - `!pay @name amount` (the `give` action; on a channel the PixFray bot reads, it's `!give` and `!pay` stays an alias; `a=` is `20` or `$20`): moves dollars between two saved fighters while the channel is live (the same Twitch check as check-ins). In order it refuses with `give_off` (config `giveEnabled` false), `no_fighter`, `give_usage` (no target or no whole amount of at least 1), `target_not_found`, `self_give`, `twitch_error`, `not_live`, `too_few_duels` (fewer than `giveMinDuels` finished duels, `{duels, need}`), `give_cap` (already gave `giveMaxPerStream` this stream), `over_cap` (`{left}`), `not_enough` (`{dollars}`) and `target_full` (`{to, room}`: the receiver's wallet can't hold the amount, so nothing moves). Hidden duel results and payouts don't count yet. The limit is per Twitch stream id (`profiles.give_stream`, `given_in_stream`). Success is `given` with `{amount, to, dollars, left}`; the command log stores the amount.
 - Check-ins (the StreamElements `checkin` action; the test site's dev chat also takes `!checkin`, Twitch EventSub chat does not): once per stream, only while Twitch's Helix `/streams` says the channel is live (cached 60 s; a Twitch error answers "try again" and is not cached). Gives `checkinPoints` (bonus capped at 1,000,000). The streak counts the channel's streams in a row that had any check-in; one missed stream is forgiven once every 7 days. With `streakBonus`, a streak of 3, 7, 14 or 30 gives +1 more, 60 gives +2, 100 gives +3, 200 gives +5 and 365 gives +10. The reply names the total and what is unspent: "@x checked in: +2 points (7-stream streak, streak bonus). 18 points, 3 unspent. Spend them at <link>", or "…, all spent." with no link. Reasons: `checked_in`, `already_checked_in`, `not_live`, `no_fighter`, `twitch_error`. On the test Worker, `POST /api/devtools/<ch>/live` with `{live, streamId?}` (DEV_TOOLS_TOKEN only) replaces the Twitch answer: `true` is live, `false` is offline, and `null` goes back to asking Twitch.
