Resolves #5758

Stacked on #5726 (levels and the end-of-game XP reveal). The base is that PR's branch, so this diff shows only this change. GitHub moves the base to main once #5726 merges. The API side is openfrontio/infra#896.

Description:

Most players die before a game ends, so today they see "XP is awarded when the game ends" and never see the reveal. With this change, the moment a player is out the client works out their XP provisionally and plays the full reveal: source cards, bar, level-ups, milestone cards and Legend. When the game ends it reconciles with the server's figure. The server stays the only authority: the client never sends its figure anywhere, and XP is still scored once, at ingest.

The provisional figure

  • The formula. src/client/ProvisionalXp.ts is a line-for-line copy of infra's computeXp.

    • Every rule value comes from /public/progression/config (xp), and nothing is hard-coded.
    • It only runs when the API's formula is 1, the revision it implements. Otherwise it falls back to the old "awarded when the game ends".
    • It passes infra's 263 reference cases (tests/testdata/progression/xp-reference-cases.json). These are generated by the real computeXp and cover every eligibility reason, game kind, lobby size, the first game of the day, team wins, leavers and multipliers.
  • Inputs at death (src/client/ProvisionalXpAtDeath.ts) come from a read-only snapshot of the simulation's own stats. They are the same per-player stats the archived record carries, and infra scores from them:

    • time alive, from the player's death tick;
    • spawned humans, for the lobby factor;
    • FFA opponents outlasted: everyone who went out before the player, which can't change after their death;
    • the first game of the day and the subscriber boost, from /users/@me (progress.daily, progress.subscriberPermille). progress.daily.day says which UTC day those counts are for, so a death after midnight UTC starts the new day from none used, as the API scores it;
    • the game config.

    For an FFA death the provisional figure is therefore exact. In team and Humans-vs-Nations games, the team's win isn't known yet, so it shows as pending.

  • When it doesn't show: if any input can't be read (no formula 1, no rules, a worker that doesn't answer, stats that never show the death), the player sees the old "awarded when the game ends".

  • Singleplayer: a singleplayer game never carries the end-of-game stats vote. The API scores it anyway (0.25×, at most 5 a day) and says so with scoresSingleplayer: true on the config (the API-side change is in the infra repo), and then the figure shows at the singleplayer rate. An API that sends neither scoresSingleplayer nor requireStatsAgreed: false predates singleplayer scoring, so no figure is shown rather than one the server would take away. Multiplayer games still need the vote in production (requireStatsAgreed).

On screen

  • At death:
    • the full reveal plays straight away, so most players now see their level-ups and milestones;
    • a small "Provisional — confirmed when the game ends" label sits above it;
    • in team games, a line notes the possible team-win bonus.
  • When the game ends the server's figure is fetched as before ("Confirming your XP…"):
    • Match: a quiet "XP confirmed", with no second reveal or celebration.
    • Higher (for example a team win): the server's numbers with the reason, and only the extra levels celebrate.
    • Lower (rare: unverified game, daily allowances, drift): the server's numbers with the reason and nothing replayed. If a celebrated level wasn't reached, it says "Adjusted to level N".
    • A gap the known reasons don't explain is logged with both totals and the inputs (no names or IDs), so a drift between the two formula copies shows up.
    • The server never answers: the figure stays, still labelled provisional.
  • Reduced motion and the existing on-screen and off-screen handling are respected.

The simulation

src/core/game/HumanStats.ts adds one read-only query, humanStats(), reached through a new worker message. It returns:

  • a copy of the humans' stats;
  • the current tick;
  • when each disconnected human disconnected.

It writes no state, uses no randomness and adds nothing to the turn stream. Game.ts and PlayerImpl.ts are untouched. The worker answers it between batches of ticks, so it always sees a whole tick.

Performance and determinism

Tick speed. The full-game benchmark (npm run perf:game) was run three times on each branch: world map, 400 bots, 3,000 ticks.

Before (#5726) This branch
Mean tick 1.98–2.15 ms 1.93–2.16 ms
p95 / p99 4.0–4.5 / 6.9–7.5 ms 3.8–4.4 / 6.7–7.2 ms
Over the 100 ms budget 0 0

There is no measurable change, which is expected: nothing is added to the tick loop.

The snapshot, taken once at the player's death: 0.03 ms with 10 humans, 0.16 ms with 50, and 0.37 ms with 125.

Determinism:

  • Every benchmark run on both branches ended on the same final game-state hash.
  • A new core test plays two identical games, one snapshotting after every tick, and checks that every tick and the final stats match.

Media

Dying with a milestone. A 9-minute FFA, the first public game of the day: +366 XP, from level 9 to 11 through the level 10 milestone. At death the full reveal plays under the provisional label. When the game ends it is quietly confirmed.

provisional-milestone.webm

At death, with the milestone card:

The full XP reveal at death with the level 10 milestone card, under the provisional label

Confirmed when the game ends:

XP confirmed when the game ends

The game behind is a real local solo game. The XP is sample data fed to the end screen, because the local dev API doesn't serve the new fields yet. Every state is covered by tests.

Testing

  • New tests:
    • the formula against all 263 reference cases;
    • inputs at death: FFA placement from deaths so far, team wins left pending, leavers, the first game of the day, fallbacks;
    • the end screen: the reveal at death including a milestone card, a match with no second celebration, a higher figure celebrating only the new levels, a lower figure with the adjustment line, unverified, drift, and the fallback without formula 1;
    • humanStats, including the determinism test;
    • the worker message and the new schema fields.
  • Full suite: 7,728 passed, 1 skipped. The only failures are the two UpdateRegister tests, which shell out to update.sh and fail the same way on Windows without this change.
  • Checks: tsc, oxlint, eslint and prettier are clean.

Please complete the following:

  • I have added screenshots for all UI updates
  • I process any text displayed to the user through translateText() and I've added it to the en.json file
  • I have added relevant tests to the test directory

A level badge (level bands, prestige emblems, the Legend crown) and an XP
bar for the account menu, player profiles and the game stats modal.

On the end-of-game screen, the game's XP is revealed a source at a time:
a caption per source rolls in over a segmented bar that climbs, pausing
with an animation at each level reached, while each source's card lands
below. Multipliers then wipe across the cards in the bonus's colours, a
subscription tier's own (Sovereign, Warlord, Vanguard), and a milestone
or Legend gets its own card. Tapping skips to the end. The modal's
buttons get the store's texture and a hover.

Every API state is handled (signed out, calculating, ineligible, result),
and nothing shows while the API reports progression is off.

Resolves #5725

CodeQL flags the regex (incomplete multi-character sanitization). These
tests only compare SVG markup, but removing the comment nodes through the
DOM is simpler to read and leaves nothing to flag.

- Parse a malformed /users/@me progress object as absent instead of
  failing the whole profile (which made the player look signed out).
- Decide "signed out" for the XP panel from auth state: a /users/@me
  failure with a live session now hides the panel rather than telling a
  signed-in player to sign in. The rule lives in ProgressionAccount and
  is shared by WinModal and GameStatsModal, so both accept a CrazyGames
  session.
- Show a player who was already a Legend with the Legend frame for the
  whole reveal.
- Remove each poll wait's abort listener when its timer fires.
- Load the profile's level independently of the profile itself, still
  dropping a response for a superseded load.
- Add a keyboard-reachable skip button for the reveal, and give the XP
  progress bars an accessible name and value text.
- Translate the prestige tab's "P{prestige}" label.

…, abortable XP fetch

- Explain games recorded ineligible as "unverified" (stats the votes did
  not agree on) instead of the generic line.
- Only play the XP reveal while the win modal is on screen: a result that
  lands after it is dismissed shows in its final state, and dismissing it
  mid-reveal jumps to the end. A panel removed mid-reveal also ends it, so
  it never comes back half-revealed and aria-busy.
- Pass pollGameXp's abort signal into the request itself (combined with its
  timeout via AbortSignal.any), so aborting cancels a request in flight.
- Default the breakdown's per-source fields and leftEarly, so XP rows
  scored under the first XP rules (no `played`/`leftEarly`) still parse.
- Read your own profile's level from the public endpoint, not the
  /users/@me copy cached at page load.
- Put the level in the nav account button's accessible name, which its
  aria-label otherwise hid from screen readers.
- Drop xpBar's unused animate/durationMs options and fix the milestone
  comment that mentioned a share button.

The API now pays +100 XP for the first eligible public game each UTC day,
win or lose, instead of +200 for the first win, and reports it as
`firstGame` in the XP breakdown. Rename the schema field, the line key and
its label ("First game of the day"). Feats stay in the breakdown but are
always 0 for now; zero lines are already left off the cards.

The subscription tiers' XP multipliers move from 1.2x / 1.3x / 1.5x to
1.25x / 1.5x / 2x, so the client now recognises Vanguard at 1250,
Warlord at 1500 and Sovereign at 2000 permille. The bonus line's percent
is still derived from the multiplier ("+100% XP (Sovereign bonus)"), and
any other value, the old ones included, shows as a plain subscriber bonus.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Most players die before the game ends, and until now the end screen only
said "XP is awarded when the game ends". The client now works out a
provisional figure the moment the local player dies, with a copy of the
API's computeXp, and swaps in the server's authoritative figure once the
game ends. Nothing is sent anywhere: the server stays the only authority.

- ProvisionalXp.ts: a faithful port of computeXp (integer math, permille
  multipliers, rounding) and ffaOutlasted. Pinned by the API-generated
  reference cases in tests/testdata/progression/xp-reference-cases.json.
- A read-only worker query (human_stats -> HumanStatsSnapshot) returns the
  humans' stats as the end-of-game record carries them, plus who is
  disconnected and since when, so the client reads the same killedAt,
  attacks/builds/conquests and FFA deaths the server will.
- ProvisionalXpAtDeath.ts derives the XpContext at death (no win, no feats,
  no leave; FFA placement from opponents out before the player; daily state
  and subscriber multiplier from /users/@me), projects the level bar, and
  reconciles the server's figure: team win / feats / unverified / daily cap
  explained, anything else logged as possible formula drift.
- ApiSchemas: optional `formula`, `xp` (XpRules) and `prestige` on the
  progression config; optional `daily` and `subscriberPermille` on
  progress. The client only shows a provisional figure for formula 1.
- GameXpPanel/WinModal: the provisional reveal stops short of any level it
  would cross (levels shown as pending); on a match the result is marked
  confirmed and only the level-up celebration plays; on a mismatch the
  server's numbers show with a line saying why. No formula or rules, or
  stats that never show the death: the old "awarded when the game ends".

A game snapshotted after every tick plays out tick for tick like one that
never was, with identical stats at the end.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Follows the API's v3 rules: the first public game of the day (ranked
included, won or lost, unscaled, not when left early) pays in place of the
first win, and feats pay 0.

- ProvisionalXp.ts: the first-game rule as the API's computeXp has it;
  firstWinClaimed -> firstGameClaimed, firstWin -> firstGame. Feat math kept.
- ApiSchemas: xp.firstWinOfDay -> firstGameOfDay; progress.daily
  .firstWinClaimed -> firstGameClaimed (an old-shape block reads as absent).
- The first game is known at death (/users/@me's daily state and the game
  type), so it is part of the provisional figure. "Feats are added when the
  game ends" only shows while the rules pay for feats.
- The provisional figure now gets the full reveal: level-ups, milestone
  cards and the Legend moment, still labelled provisional. When the server
  answers: a match is a quiet "XP confirmed" with nothing replayed; a higher
  figure (a team win) climbs on and celebrates only the levels past those
  already celebrated; a lower one shows the server's numbers with nothing
  replayed and, if it ends below a celebrated level, "Adjusted to level N".
- reconcileXp: a first-game difference is put down to the day's allowances
  (daily_cap), not drift; team_win is the win line alone.
- Reference cases regenerated from the API (263; feat cases also run with
  their own rules, featXp 50).

Walkthrough

The change adds a client-side provisional XP calculation based on human-stat snapshots. The win modal displays provisional XP when a player is out, then presents and reconciles the server result when the game ends.

On a phone the bar under the XP reveal is under 200px wide, so the
centred "+1,150 XP" counter ran straight into the truncated
"444 / 2,41…" at its right end. Below a 16rem bar (a container query on
the bar's column) the two now stack, centred, at a fixed height so
nothing moves during the reveal. Wider bars keep today's layout.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The stats modal's compact reveal panel becomes a static card between the
game summary and the tabs: the total, the level change (with a Milestone
chip and glow at 10/25/50/75/100) or the level and progress, each source at
its base value in three columns (one on a phone), and each multiplier as its
own line with the XP it added.

The XP endpoint only returns the caller's own record, so any 200 is shown,
including why a game didn't earn XP and the coming before_progression
reason. A 404 shows "Calculating XP…" and polls only for the player's own
game (account history or own profile) that ended in the last 10 minutes;
otherwise it shows nothing, as before.

The API rounds once over subtotal x game x subscriber, so a multiplier's
amount is total - subtotal only when it is the only one; with both, the
lines show no amount rather than a guessed split.

Keeps both new progression keys (xp_before_levels, xp_confirmed) in sorted
order, and drops the provisional reveal's check for the panel's compact mode,
which the base removed when the past-game card replaced it.

Main moved src/core into packages/ (#5805). Resolves the two import
conflicts (PlayerProfileModal, NavAccountMenu) by keeping this branch's
extra types on the new @openfront/shared/ApiSchemas path, and points the
levels code and tests this branch added at the new packages:
ApiSchemas -> @openfront/shared, EventBus -> @openfront/engine-lib,
GameUpdates -> @openfront/engine-api.

Brings in main's move of src/core into packages/ (#5805) via
player-levels-ui.

- HumanStats: the snapshot type, HumanStatsSnapshot, moves to
  engine-api's game/GameTypes next to PlayerProfile/PlayerBorderTiles, so
  the worker protocol (engine-api) and WorkerClient (client) can name it
  without importing the engine. humanStatsSnapshot() stays in the engine
  as packages/engine/src/game/HumanStats.ts.
- GameRunner, WorkerClient, WinModal: keeps this branch's additions
  (humanStats(), the human_stats worker message, Progress and
  invalidateUserMe) on main's new imports.
- Points the provisional-XP code and tests at the new packages.

Re-synced with main (69f0703). GameXpPanel.ts and WinModal.ts take this branch's side after confirming main's copy equals #5726's last head (812cc15), so #5726's review fixes are already in them; the line_other residual and the config-memo TTL live in Progression.ts and ProgressionApi.ts, identical to main. ApiSchemas.ts and en.json merged cleanly with #5778's changes. The diff against main is now this PR's own 19 files.

🟡 Minor · Suppress provisional XP when progress inputs are unavailable. · ProvisionalXpAtDeath.ts:189-190

src/client/ProvisionalXpAtDeath.ts:189-190
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Suppress provisional XP when progress inputs are unavailable.

ProgressSchema accepts progress without daily or subscriberPermille. provisionalXpContext then supplies NO_DAILY_XP and 1000, so buildProvisionalXp can display a figure based on assumed values. The schema tests cover tolerant parsing, but they do not define omitted values as valid provisional-XP inputs. Return the existing null fallback before calling provisionalXpContext.

Suggested fix
   const rules = provisionalXpRules(input.progression);
   if (rules === null || !apiScoresGame(input.progression, input.config)) {
     return null;
   }
+  if (
+    input.progress.daily === undefined ||
+    input.progress.subscriberPermille === undefined
+  ) {
+    return null;
+  }
   const derived = provisionalXpContext(input);

- WorkerClient.humanStats rejects after 5 s and drops its handler, as
  playerInteraction does; the worker has no error reply for it, so a
  failure there surfaces as the timeout.
- buildProvisionalXp returns null when /users/@me's progress lacks the
  day's allowances or the subscriber boost: the API always sends both, and
  reading their absence as a fresh day at 1x could overstate the figure.

The provisional figure at death asked for a fresh /users/@me by dropping
the page's cached copy. A failed ask then cached `false` for the session,
so the XP section went quiet and the game-end figure never showed. It now
asks past the cache (fetchUserMeUncached), falling back to the page's
progress, and the game-end path reads the cached copy as before.

A provisional figure that arrived while the panel was off screen, or whose
reveal was cut short by closing the modal, never played; the server's
figure then skipped the levels and milestones it assumed were seen. The
panel now remembers which provisional figure revealed on screen, and only
then confirms quietly or celebrates just the extra levels; otherwise the
server's figure plays in full.

Both findings were real and are fixed in 2628ee8:

  1. Failed /users/@me at death: the death-time refresh no longer invalidates the shared cache. A new fetchUserMeUncached() reuses getUserMe's request and parsing without reading or writing the cache; loadProvisionalXp uses its fresh progress and falls back to the cached copy if it fails. The game-end path reads the cached copy exactly as before. Tests: fresh allowances are used; a failed fresh fetch falls back to cached progress and the game-end poll still shows the server's figure; the cache is never replaced by a failure.
  2. Celebrations when the provisional figure arrives off screen: GameXpPanel records the provisional figure whose reveal actually started on screen (revealedProvisional), and clears it if the panel goes off screen mid-reveal. The matched/higher/lower shortcuts apply only when that's the figure being reconciled; otherwise the server's figure gets the full reveal. Tests: off-screen provisional then a matched result, then a higher team-win result, and a reveal cut short by closing the modal: each plays the full reveal with its milestone card. The on-screen matched case still confirms quietly.

Confirming CodeRabbit's finding above — it is real, and it is a consequence of the fix for the off-screen high rather than something pre-existing.

revealedProvisional records that the reveal started on screen, not that it finished. In willUpdate:

if (reconciled.outcome.matched) {
  // Confirmed as shown. A reveal still playing carries on.
  return;                               // <- correctly preserves an active reveal
}
if (s.data.breakdown.total > shown.breakdown.total) {
  this.startReveal(s.data, {
    kind: "celebrate",
    from: samePrestige ? endPosition(shown) : 0,
    celebrated: samePrestige ? shown.after.level : 0,
    ...
  });                                   // <- no check on this.reveal !== null
}

The matched branch explicitly handles the still-playing case. The higher-result branch doesn't: it calls startReveal, which clears the provisional's timers and restarts at endPosition(shown) with celebrated: shown.after.level.

Failure scenario: a team win reconciles higher while the provisional reveal is mid-animation at, say, level 13 of a 12→15 climb. The reveal is torn down, restarted from the end of the provisional, and every level up to 15 is marked already-celebrated — so the player never sees 14 or 15 land, despite the animation never having reached them.

Narrow (it needs a higher reconciliation to land inside the animation window, which is the team-win case), hence minor rather than more.

Both of CodeRabbit's suggestions work. The one that fits the existing shape best is probably to track completion separately from start — revealedProvisional is set when startReveal runs; a second field (or clearing reveal to null on completion and testing that) would let the higher-result branch distinguish "seen in full" from "seen so far". Deferring the reconciliation until the reveal finishes is the other option, but it delays the server's figure behind an animation, which is the thing the reveal machinery generally tries to avoid.

For the record, the two highs from the previous round both look properly fixed to me:

  • fetchUserMeUncached() gets the fresh profile without touching the shared __userMe cache, so a failed death-time refresh can no longer poison the session and strand the server's figure. invalidateUserMe is gone from WinModal.ts.
  • Tracking revealedProvisional as the figure rather than a boolean is stronger than the flag that was suggested — it also covers the case where a different provisional was the one on screen.

…l got to

A server figure above the provisional one that arrives while the provisional
reveal is still playing now picks up from that reveal's bar, counter and
level, so levels it hadn't reached yet still get their moment.

@Celant this crossed with 68d3f11, which fixes it. The higher-result branch now reads the live provisional reveal (this.reveal, before startReveal resets it), and the celebration starts from that frame's bar position, counter, level and Legend state. It only falls back to the provisional figure's end when no reveal is playing. So in your 12→15 example, cut off at 13, the celebration picks up at 13, plays 14 and 15, then the team win's levels, and nothing is celebrated twice. The server's figure isn't deferred. Regression test: the game ends at the provisional reveal's first level-up (10) and a team win comes back; 11, 12 and 13 all play (without the fix, only 13 does). Thanks for confirming the two highs.

🤖 Claude Code Review

Verdict: No issues found. Checked for bugs and CLAUDE.md compliance.

Findings: 0 critical · 0 high · 0 medium · 0 low

What was checked:

  • Engine import rules and determinism: HumanStats.ts, GameRunner.humanStats() and the worker's human_stats case import only engine-api. They don't use Math.random, Date.now or the inexact Math functions, and they only read game state. The client reaches the engine only through the worker.
  • i18n: every new string goes through translateText() and has an entry in en.json. No other translation files are changed.
  • Logic: worker request/response pairing and timeout cleanup; the xpPolling guards when the game ends while the provisional figure is still loading; reconciliation of match, higher and lower server figures, including the higher case continuing from the live reveal frame; the UTC day rollover and the FFA "outlasted" count.
