-
-Add `adapter-multiplayer-firebase`, a Firebase Realtime Database backend for the jsPsych multiplayer API — real cross-device multiplayer with essentially no server to write or host.
-
-It implements the same `MultiplayerAdapter` contract as the local and JATOS adapters, so plugins behave identically on any of them, and sits between them on the infrastructure spectrum: broader reach than the same-browser local adapter, far less setup than a self-hosted JATOS server. Because the contract's `getAll()`/`get()` are synchronous while Firebase reads are async, the adapter keeps an in-memory mirror of the session node (kept live by a single `onValue` listener) and does not resolve `connect()` until the first snapshot arrives (rejecting on a rules denial or timeout). Each participant's payload is JSON-encoded as a string so pushes round-trip exactly over RTDB's JSON coercion, a `.info/connected` handler re-arms `onDisconnect` and re-pushes after a transient network blip so a still-present participant is never erased, and an optional `useUidAsParticipantId` mode enables the recommended session-locked security rules: uid-as-slot-key (no participant can write another's slot) plus first-write-wins session binding — `connect()` registers a `mp-sessions-memberships/<uid> = sessionId` record the server-evaluated rules make immutable and then require on every session read/write, so a client identity can only ever touch the session it first joined. The recommended rules ship as `database.rules.json` (with a `firebase.json` for the emulator suite). `firebase` is a peer dependency. Built against a local interface mirroring the multiplayer API (jsPsych#3694), so it carries no build-time dependency on the unreleased core, and the whole adapter is unit-tested against an in-memory backend fake with zero credentials.

-Add `plugin-multiplayer-countdown`, a synchronized group timer (countdown or count-up) for the jsPsych multiplayer API.
-
-Every participant pushes its own start timestamp into its own slot, and each client derives the displayed time from the **minimum** timestamp across all slots — a coordination-free consensus (no elected anchor, no single point of failure) in the same spirit as `plugin-multiplayer-role`'s ordering. Late joiners and refreshes resume at the group's actual remaining time for free, and the pure consensus core (`startedAtKey` / `resolveStartedAt` / `computeRemaining` / `computeElapsed` / `formatTime`) is exposed as statics on the default export so demos can render their own synced display.

-Add `plugin-multiplayer-draw`, a real-time collaborative drawing canvas for the jsPsych multiplayer API.

-Every participant draws on one shared canvas; strokes from everyone appear live on everyone else's screen. Includes pen/eraser tools, a fixed color palette, brush sizes, and undo/redo buttons that only ever act on the participant's own strokes. Where `plugin-multiplayer-chat` pushes once per message, this plugin pushes continuously while a stroke is active (throttled and point-decimated), making it the first plugin that stresses the multiplayer API's `subscribe` primitive at a genuinely high rate. Full repaints (triggered by undo or a canvas resize) paint strokes in a global timestamp order so the eraser's `destination-out` compositing behaves consistently across clients. Built against a local interface mirroring the multiplayer API (jsPsych#3694), so it carries no build-time dependency on the unreleased core.

-Add `plugin-multiplayer-ready`, a participant-facing ready / check-in barrier for the jsPsych multiplayer API.
-
-It packages the common lobby / waiting-room pattern into a single declarative trial: show a prompt and a ready button, push `{ ready: true }` (optionally merged with `push_data`) into the shared group session when the participant clicks, display a waiting message, and end the trial once `expected_players` members are ready (or an optional `timeout` elapses while waiting for the rest of the group). Unlike `plugin-multiplayer-sync`, it owns the check-in UI and the "everyone is ready" condition, and standardizes on a `ready: true` flag so other plugins and examples can reliably gate on group readiness.

-Add `plugin-multiplayer-reference-game`, a repeated referential communication game ("tangrams"; Hawkins, Frank & Goodman 2020) for two players on the jsPsych multiplayer API.
-
-Two players are paired as a fixed director and matcher and see the same objects, each in an independently scrambled layout; only the director sees which objects are targets (and, for more than one, in what order). They communicate over an integrated free-text chat, the matcher assigns objects to the director's ordered target slots (a single click when there is one target), and both then see feedback with the true answer revealed. The published "sequential" (one target, click) and "unconstrained" (all N objects are ordered targets, reproduce the whole board) conditions are the same task with two parameters turned differently — `stimuli` length and `targets` length — so one configurable plugin covers both, plus everything in between. Like `plugin-multiplayer-chat` it is a continuously-open, `subscribe`-driven trial: the matcher's submitted assignment is the shared trigger on which both clients score, show feedback, and end. Object/target counts, scramble mode, chat direction and limits, scoring rule, feedback content, and an optional pre-submit interaction log are all parameters. Composes with `plugin-multiplayer-role` (director/matcher) and `plugin-multiplayer-sync` (lobby). Built against a local interface mirroring the multiplayer API (jsPsych#3694), so it carries no build-time dependency on the unreleased core.

Both plugins previously treated every `wait()` rejection as a timeout (a leftover from before jsPsych#3694 exported a typed `MultiplayerTimeoutError`), so a throwing `wait_for` predicate or an adapter/backend error would silently finish the trial with `timed_out: true` and call `on_timeout`, hiding the real failure in `wait_error`'s message.

-Add `plugin-multiplayer-choice`: a simultaneous group-decision primitive. Each participant picks one of the same options; the trial pushes that choice and waits (a barrier) until all `expected_players` have chosen, then optionally reveals the outcome. It is the engine under simultaneous-move paradigms (prisoner's dilemma, public-goods contributions, dictator/coordination games), packaging the choose → push → wait → reveal flow as one declarative trial. Two reveal modes: `reveal_mode: "players"` (default) lists who chose what; `reveal_mode: "tally"` shows only per-option counts and the plurality winner — an anonymous group poll, with `record_choices_by_player: false` to keep the recorded data anonymous too (this subsumes the separately-proposed `plugin-multiplayer-vote`). Includes a `timeout` that degrades to a partial group, an optional `payoff(choices, me)` hook (off by default, so the plugin stays a pure decision primitive), `player_label`/`button_html` display hooks, always-recorded aggregate data (`tally`/`winner`/`is_tie`/`tied_options`), a barrier count bounded by the option range (a stale out-of-range pick can neither lift the barrier nor skew `n_players`), and static access to the pure core (`collectChoices`/`countChosen`/`tally`/`plurality`).

-Add `plugin-multiplayer-match`: partition a multiplayer group into matched sub-groups (pairs by default, or triads/larger) by deterministic consensus — every client independently computes the same partition from the shared group-session snapshot, with no coordinator. It is the foundational primitive under pairwise/small-group paradigms (trust game, ultimatum, dyadic negotiation) and composes with `plugin-multiplayer-role` (assign roles *within* a group via `position`). Runs as a short barrier (like `plugin-multiplayer-role`), supports `ordered`/`join_order`/`random` (seeded, per-round) pairing strategies and `error`/`spectator`/`smaller_group` leftover policies for non-divisible counts, fails loud on timeout, and exposes the pure core (`buildMatches`) plus partner accessors (`getMyPartners`/`getMyGroup`/`getMyPosition`/`getMatchMap`) as statics for downstream trials.

-Add a `require_message_before_response` parameter. When true, the matcher cannot commit a selection until the director has sent at least one chat message this round — while gated, matcher grid clicks are ignored and a brief hint is shown. This makes the plugin faithful to Hawkins, Frank & Goodman (2020) Exp. 2, whose client blocked the matcher's click behind `messageSent`, guaranteeing a referring expression on every trial. Defaults to `false` (unchanged behavior); inert with a warning when `chat_enabled` is false (gating with no channel would deadlock the matcher). Applies to both the `click` and `assign_slots` response modes. Only the partner's messages open the gate, so neither the matcher's own message nor a third participant's counts. Blocked clicks are recorded as `gated_click` events in `interaction_history` when `save_interaction_history` is on.
-
-Chat messages now also carry the `round` they were sent during. This makes the gate exact under `chat_persists: true`, where every round shares one log: an earlier round's message never pre-opens the gate, and the director's message for the current round still counts when it lands before the matcher's trial is constructed (the two clients do not enter a round at the same moment). Saved `chat_transcript` entries gain the same `round` field; transcripts written by earlier versions still merge and render.

+## 0.2.0
+
+### Minor Changes
+
+- [#43](https://github.com/jspsych/jspsych-multiplayer/pull/43) [`565ff2f`](https://github.com/jspsych/jspsych-multiplayer/commit/565ff2f67a7dbda4cc86a81b3c2b361ba91225da) Thanks [@htsukamoto5](https://github.com/htsukamoto5)! - Add `adapter-multiplayer-firebase`, a Firebase Realtime Database backend for the jsPsych multiplayer API — real cross-device multiplayer with essentially no server to write or host.
+
+  It implements the same `MultiplayerAdapter` contract as the local and JATOS adapters, so plugins behave identically on any of them, and sits between them on the infrastructure spectrum: broader reach than the same-browser local adapter, far less setup than a self-hosted JATOS server. Because the contract's `getAll()`/`get()` are synchronous while Firebase reads are async, the adapter keeps an in-memory mirror of the session node (kept live by a single `onValue` listener) and does not resolve `connect()` until the first snapshot arrives (rejecting on a rules denial or timeout). Each participant's payload is JSON-encoded as a string so pushes round-trip exactly over RTDB's JSON coercion, a `.info/connected` handler re-arms `onDisconnect` and re-pushes after a transient network blip so a still-present participant is never erased, and an optional `useUidAsParticipantId` mode enables the recommended session-locked security rules: uid-as-slot-key (no participant can write another's slot) plus first-write-wins session binding — `connect()` registers a `mp-sessions-memberships/<uid> = sessionId` record the server-evaluated rules make immutable and then require on every session read/write, so a client identity can only ever touch the session it first joined. The recommended rules ship as `database.rules.json` (with a `firebase.json` for the emulator suite). `firebase` is a peer dependency. Built against a local interface mirroring the multiplayer API (jsPsych#3694), so it carries no build-time dependency on the unreleased core, and the whole adapter is unit-tested against an in-memory backend fake with zero credentials.

No behavior change; each package's local `MultiplayerApiLike` mirror gained an `update` member to match.
+
+- [#29](https://github.com/jspsych/jspsych-multiplayer/pull/29) [`2650fa9`](https://github.com/jspsych/jspsych-multiplayer/commit/2650fa9da7a39cd74fb7ac9fb9c982ef99e1f082) Thanks [@htsukamoto5](https://github.com/htsukamoto5)! - Fix unreadable chat transcript: the plugin shipped no CSS, so sender and message text rendered as bare unstyled `<span>`s with nothing between them (e.g. "AliceHello"). Inject minimal scoped styles (boxed log, one message per line, bold sender label with a colon separator, own-message highlight) so the transcript is legible out of the box.
+
+  Also clarifies the chat-room example's name prompt ("Choose a display name — this is what other participants will see you as in the chat") since testers read the original wording as naming the chat room itself.
+

The plugins previously used bare `setTimeout` and only cleared handles on their own end paths, so external termination — exactly what multiplayer sync timeouts and host-ended sessions do — left timers alive.

Each participant picks one of the same options; the trial pushes that choice and waits (a barrier) until all `expected_players` have chosen, then optionally reveals the outcome. It is the engine under simultaneous-move paradigms (prisoner's dilemma, public-goods contributions, dictator/coordination games), packaging the choose → push → wait → reveal flow as one declarative trial. Two reveal modes: `reveal_mode: "players"` (default) lists who chose what; `reveal_mode: "tally"` shows only per-option counts and the plurality winner — an anonymous group poll, with `record_choices_by_player: false` to keep the recorded data anonymous too (this subsumes the separately-proposed `plugin-multiplayer-vote`). Includes a `timeout` that degrades to a partial group, an optional `payoff(choices, me)` hook (off by default, so the plugin stays a pure decision primitive), `player_label`/`button_html` display hooks, always-recorded aggregate data (`tally`/`winner`/`is_tie`/`tied_options`), a barrier count bounded by the option range (a stale out-of-range pick can neither lift the barrier nor skew `n_players`), and static access to the pure core (`collectChoices`/`countChosen`/`tally`/`plurality`).

Only a timeout now proceeds with a partial snapshot (`timed_out: true`, runs `on_timeout`); any other rejection rethrows so the trial halts loudly instead of masquerading as a timeout.

+
+  Every participant pushes its own start timestamp into its own slot, and each client derives the displayed time from the **minimum** timestamp across all slots — a coordination-free consensus (no elected anchor, no single point of failure) in the same spirit as `plugin-multiplayer-role`'s ordering. Late joiners and refreshes resume at the group's actual remaining time for free, and the pure consensus core (`startedAtKey` / `resolveStartedAt` / `computeRemaining` / `computeElapsed` / `formatTime`) is exposed as statics on the default export so demos can render their own synced display. Built against a local interface mirroring the multiplayer API (jsPsych#3694), so it carries no build-time dependency on the unreleased core.

+
+  Every participant draws on one shared canvas; strokes from everyone appear live on everyone else's screen. Includes pen/eraser tools, a fixed color palette, brush sizes, and undo/redo buttons that only ever act on the participant's own strokes. Where `plugin-multiplayer-chat` pushes once per message, this plugin pushes continuously while a stroke is active (throttled and point-decimated), making it the first plugin that stresses the multiplayer API's `subscribe` primitive at a genuinely high rate. Full repaints (triggered by undo or a canvas resize) paint strokes in a global timestamp order so the eraser's `destination-out` compositing behaves consistently across clients. Built against a local interface mirroring the multiplayer API (jsPsych#3694), so it carries no build-time dependency on the unreleased core.

It is the foundational primitive under pairwise/small-group paradigms (trust game, ultimatum, dyadic negotiation) and composes with `plugin-multiplayer-role` (assign roles _within_ a group via `position`). Runs as a short barrier (like `plugin-multiplayer-role`), supports `ordered`/`join_order`/`random` (seeded, per-round) pairing strategies and `error`/`spectator`/`smaller_group` leftover policies for non-divisible counts, fails loud on timeout, and exposes the pure core (`buildMatches`) plus partner accessors (`getMyPartners`/`getMyGroup`/`getMyPosition`/`getMatchMap`) as statics for downstream trials.

The match barrier now calls `push()` then `wait()`, and distinguishes a genuine readiness timeout (`MultiplayerTimeoutError`, matched by error name) from other rejections: a real timeout ends the trial gracefully (`timed_out: true`), while a backend/push failure now propagates loudly instead of being mislabelled as a timeout.

+
+  It packages the common lobby / waiting-room pattern into a single declarative trial: show a prompt and a ready button, push `{ ready: true }` (optionally merged with `push_data`) into the shared group session when the participant clicks, display a waiting message, and end the trial once `expected_players` members are ready (or an optional `timeout` elapses while waiting for the rest of the group). Unlike `plugin-multiplayer-sync`, it owns the check-in UI and the "everyone is ready" condition, and standardizes on a `ready: true` flag so other plugins and examples can reliably gate on group readiness.

Both plugins previously treated every `wait()` rejection as a timeout (a leftover from before jsPsych#3694 exported a typed `MultiplayerTimeoutError`), so a throwing `wait_for` predicate or an adapter/backend error would silently finish the trial with `timed_out: true` and call `on_timeout`, hiding the real failure in `wait_error`'s message.

+# @jspsych-multiplayer/plugin-multiplayer-reference-game
+
+## 0.2.0
+
+### Minor Changes
+
+- [#42](https://github.com/jspsych/jspsych-multiplayer/pull/42) [`a836cd6`](https://github.com/jspsych/jspsych-multiplayer/commit/a836cd65d809ef7d0f10cf1190fe3687e8f29758) Thanks [@Mandyx22](https://github.com/Mandyx22)! - Add `plugin-multiplayer-reference-game`, a repeated referential communication game ("tangrams"; Hawkins, Frank & Goodman 2020) for two players on the jsPsych multiplayer API.
+
+  Two players are paired as a fixed director and matcher and see the same objects, each in an independently scrambled layout; only the director sees which objects are targets (and, for more than one, in what order). They communicate over an integrated free-text chat, the matcher assigns objects to the director's ordered target slots (a single click when there is one target), and both then see feedback with the true answer revealed. The published "sequential" (one target, click) and "unconstrained" (all N objects are ordered targets, reproduce the whole board) conditions are the same task with two parameters turned differently — `stimuli` length and `targets` length — so one configurable plugin covers both, plus everything in between. Like `plugin-multiplayer-chat` it is a continuously-open, `subscribe`-driven trial: the matcher's submitted assignment is the shared trigger on which both clients score, show feedback, and end. Object/target counts, scramble mode, chat direction and limits, scoring rule, feedback content, and an optional pre-submit interaction log are all parameters. Composes with `plugin-multiplayer-role` (director/matcher) and `plugin-multiplayer-sync` (lobby). Built against a local interface mirroring the multiplayer API (jsPsych#3694), so it carries no build-time dependency on the unreleased core.
+
+- [#67](https://github.com/jspsych/jspsych-multiplayer/pull/67) [`d6926f8`](https://github.com/jspsych/jspsych-multiplayer/commit/d6926f8d702636af0e601e7c6eb1b15c2d0d3529) Thanks [@htsukamoto5](https://github.com/htsukamoto5)! - Add a `require_message_before_response` parameter. When true, the matcher cannot commit a selection until the director has sent at least one chat message this round — while gated, matcher grid clicks are ignored and a brief hint is shown. This makes the plugin faithful to Hawkins, Frank & Goodman (2020) Exp. 2, whose client blocked the matcher's click behind `messageSent`, guaranteeing a referring expression on every trial. Defaults to `false` (unchanged behavior); inert with a warning when `chat_enabled` is false (gating with no channel would deadlock the matcher). Applies to both the `click` and `assign_slots` response modes. Only the partner's messages open the gate, so neither the matcher's own message nor a third participant's counts. Blocked clicks are recorded as `gated_click` events in `interaction_history` when `save_interaction_history` is on.
+
+  Chat messages now also carry the `round` they were sent during. This makes the gate exact under `chat_persists: true`, where every round shares one log: an earlier round's message never pre-opens the gate, and the director's message for the current round still counts when it lands before the matcher's trial is constructed (the two clients do not enter a round at the same moment). Saved `chat_transcript` entries gain the same `round` field; transcripts written by earlier versions still merge and render.

Also fixes the same timeout-mislabeling bug already patched in `plugin-multiplayer-sync`/`plugin-multiplayer-ready` — only a rejection whose `error.name === "MultiplayerTimeoutError"` is now recorded as `timed_out: true`; any other `wait()`/`push()` rejection (a throwing `ready` predicate, an adapter/backend error) propagates and fails the trial loudly instead.

+- [#33](https://github.com/jspsych/jspsych-multiplayer/pull/33) [`33d337e`](https://github.com/jspsych/jspsych-multiplayer/commit/33d337e3ca02ab8374c4f137d2a9bd4cef19566c) Thanks [@Mandyx22](https://github.com/Mandyx22)! - Add `plugin-multiplayer-scoreboard`: an end-of-game scoreboard for multiplayer experiments. Each client contributes its final `score`, the trial waits (a barrier) until the group has reported, then every client independently computes the same ranked leaderboard from the shared group-session snapshot — no coordinator, no extra round-trip — and renders it locally with its own row highlighted. Supports ascending/descending sort, standard/dense tie ranking, an `on_timeout` hook, timeouts that degrade to a partial board, and static accessors (`getMyRank`/`getMyScore`/`getLeaderboard`) for branching downstream trials.

The plugin already pushed and waited as two separate calls, so there is no behavior change — this only trims dead interface surface.
