Summary

  • Adds a <tutorial-panel> HUD controller docked in the bottom HUD column directly above the control panel, guiding new players through their first game in 20 steps: spawn → attack the wilderness → troop-count tip → troop growth rate → attack ratio bar → capture tribes (nearest 2–3 marked, stays up until a City is affordable) → build a City (1) → propose an alliance with the nearest neutral/friendly nation → traitor info → Factory (2) → factory info → Port (3) → port info (bulleted) → Warship (7) → Missile Silo (5) → launch an Atom Bomb (8, gated on a fully built and loaded silo) → one "Got it" stop each for Atom Bomb / Hydrogen Bomb / MIRV / SAM Launcher. It shows on every game until closed; closing offers "Hide for this game" / "Don't show again" (persisted through UserSettings), finishing also marks it dismissed, and every step has a Skip (Got it / Skip live in the panel header to keep it short).
  • Steps complete from real sim state (PlayerView) rather than intents; steps that don't fit the game's config (no tribes/nations, unit disabled, alliances off) are skipped and the "Step n of N" count adapts (frozen at its post-spawn snapshot so it can't shrink as bots die). Build/launch steps interpolate the player's actual keybinds; while unaffordable they show "Attack neighbors to steal their land, conquer them to take their gold. You need {cost} for a {unit}." driven by live cost polling, and the atom step shows a "silo is loading" message until a ready silo exists.
  • The panel drives the rest of the HUD over the EventBus: TutorialHighlightEvent rings the troop bar / growth rate / ratio bar / gold box and puts a loud treatment (1.3x scale, gold border/fill, bobbing arrow) on the highlighted unit-hotbar button (ControlPanel, UnitDisplay). The capture-tribes and propose-alliance steps mark the nearest tribes / a neutral-or-friendly nation (relations polled and refreshed as they decay) with the game's target crosshair: GameView.setMarkedPlayers() ORs the tutorial's set into the isTransitiveTarget predicate feeding the name pass, so marks render exactly like real targeted players.
  • General (non-tutorial) rendering change, per design: any targeted player's name row (name, status icons, flag/emoji) now bypasses the zoom cull, boosted to the smallest size that survives it — so a target mark stays findable at any zoom. Same mechanism as the existing hovered-name bypass, driven by the target status flag already in the player-data texture (shader-only change).
  • The step logic lives in a pure TutorialProgress class (Tutorial.ts) with unit tests; the Lit element (TutorialPanel.ts) only builds the context snapshot and renders. New tutorial.* strings in en.json; the only src/core change is a tested UserSettings boolean pair.

Test plan

  • npx vitest tests/Tutorial.test.ts tests/UserSettings.test.ts --run (step ordering incl. build/alliance/nuke chains, linger, Got-it/Skip gating, config-based skipping, affordability gating, counter stability, dismissal persistence) plus TranslationSystem — all passing; tsc --noEmit, npm run lint, Prettier clean.
  • Headless Chromium runs of real singleplayer games: full step progression on live sim state; hotbar and control-panel highlights for every step; tribe/nation crosshair marks (nearest-3 selection, relation filter, cleared on skip/close, visible at full-map zoom via the cull bypass); silo loading→armed transition and a real atom launch advancing the tour; a real alliance request accepted by the nation AI completing the alliance step; earn-gold waiting texts with real costs; completion → dismissed flag.

🤖 Generated with Claude Code

Adds a <tutorial-panel> HUD controller that walks new players through
their first game: spawn, attack the wilderness, watch troops, attack a
bot, learn about gold, then save up for and build a City. Steps complete
from real sim state (PlayerView) polled each tick, and the pure step
logic (TutorialProgress) is unit tested.

The panel talks to the rest of the HUD over the EventBus:
TutorialHighlightEvent puts a pulsing ring on the troop bar, gold box
or the City build button, and TutorialStateEvent defers the bottom-left
in-game ad until the tutorial is closed. Closing offers "Hide for this
game" or "Don't show again" (persisted via UserSettings); finishing
also marks it dismissed.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Move the panel into the top-right stack under the game control bar and
let players drag it by its header (clamped to the viewport). Since it no
longer shares the bottom-left corner with the in-game ad, drop the ad
deferral. Add a Skip button that moves past the current step.

🤖 Claude Code Review

Verdict: No blocking issues found. Findings: 0 critical, 0 major, 0 minor.

Reviewed the diff for CLAUDE.md compliance (i18n via translateText()/en.json, src/core determinism/testing rules) and for bugs/logic errors, using four independent reviewer passes plus targeted validation of every candidate finding.

Two candidate issues were raised internally and both were rejected after verification:

  • A claim that TutorialPanel.tick() permanently deactivates itself because game.myPlayer() is null on the first tick. Verified against GameImpl.addPlayers() (called at game construction, before any spawn-phase ticks) — human players are registered from tick one, so myPlayer() is non-null when the panel first ticks. False positive.
  • A claim that the new UserSettings.tutorialDismissed()/setTutorialDismissed() methods (in src/core/game/UserSettings.ts) violate the "all src/core changes must include tests" rule. Technically untested, but this trivial getter/setter pair exactly mirrors an existing, already-untested pattern (helpMessages/toggleHelpMessages and ~10 similar pairs) in the same file — a convention the codebase doesn't otherwise enforce. Not actionable.

Nice, well-decoupled implementation overall (EventBus-driven highlighting, state-driven step progression rather than intent-driven, full i18n coverage for new strings).

Walkthrough

Adds an in-game tutorial with progress tracking, localized instructions, a draggable panel, persistent dismissal, HUD highlights, and map glows for tutorial tribes.

Changes

Tutorial HUD flow

Layer / File(s) Summary
Tutorial progress model
src/client/hud/layers/Tutorial.ts, src/core/game/UserSettings.ts, resources/lang/en.json, tests/Tutorial.test.ts
Defines tutorial steps and context-based progression. Supports acknowledgment, skipping, applicability checks, completion delays, dismissal settings, localized text, and Jest coverage.
Tutorial panel and renderer wiring
src/client/hud/layers/TutorialPanel.ts, src/client/hud/GameRenderer.ts, index.html
Adds the tutorial panel, builds context from game state, handles dragging and dismissal, renders step content, and mounts the panel in the renderer lifecycle.
HUD highlight consumers
src/client/hud/layers/ControlPanel.ts, src/client/hud/layers/UnitDisplay.ts, src/client/styles.css
Applies tutorial highlight events to troop, gold, city, port, and factory controls with a pulsing gold animation.
Tutorial tribe map glow
src/client/view/GameView.ts, src/client/WebGLFrameBuilder.ts, src/client/render/gl/*
Stores explicit glowing player IDs and renders them with a minimum glow strength, including when configured glow strength is disabled.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 99584

The tutorial adds persistent first-game guidance and HUD highlighting, but merge readiness remains moderate because the current change may fail lint, can hide the tutorial before it is usable in some player states, and may present an inconsistent City hotkey.

Use a kebab-case keyframe name.

Rename tutorialHighlight and its reference to tutorial-highlight. Stylelint rejects the current keyframe name, so linting fails.

Proposed fix
-  animation: tutorialHighlight 1.2s ease-in-out infinite;
+  animation: tutorial-highlight 1.2s ease-in-out infinite;

Re-evaluate player eligibility after temporary unavailability.

When TutorialPanel.tick() finds no player or a dead spawned player, setActive(false) prevents all later eligibility checks. The controller continues to tick, but if (!this.active) return exits first. A respawned player can therefore remain without the tutorial. Track temporary unavailability separately from the user's hide choice, and add a regression test.

Normalize the city hotkey before displaying it.

This code passes the raw persisted key. UnitDisplay.ts strips Digit and Key before showing hotkeys. Therefore, a stored value such as Digit1 appears as Digit1 in the tutorial but as 1 in the hotbar.

Use the same normalization, preferably through a shared helper, so the tutorial instruction matches the control.

🤖 Claude Code Review

Verdict: No blocking issues found. Findings: 0 critical, 0 major, 0 minor.

Reviewed the full diff (10 files, +662/-5) across two independent CLAUDE.md-compliance passes and two independent bug/security passes (diff-only and introduced-code-focused), then validated every candidate finding against the actual repo state before including anything here.

Two candidate issues were raised internally and both were rejected after verification:

  • src/core/game/UserSettings.ts — new tutorialDismissed()/setTutorialDismissed() getter/setter pair is untested, which looks like it violates CLAUDE.md's "all src/core changes must include tests" rule. On inspection, UserSettings.ts already has 11 structurally identical simple boolean getter/setter pairs (emojis/toggleEmojis, alertFrame/toggleAlertFrame, helpMessages/toggleHelpMessages, etc.) with zero test coverage in tests/UserSettings.test.ts, which otherwise thoroughly covers the file's non-trivial logic (loadouts, keybind scoping, clamping/migration). This PR follows an established, accepted convention rather than introducing an isolated gap — not actionable.
  • TutorialPanel.tick() — a claim that the panel permanently disables itself if game.myPlayer() is null on its first tick (e.g. before the local player's view is populated), silently hiding the tutorial for the whole game. Traced the actual call chain: renderer.tick() only ever fires from inside ClientGameRunner's game-update callback, after GameView.update() has already resolved _myPlayer from that same update; GameImpl registers all human players synchronously at construction and every tick's PlayerUpdate includes clientID from the first emission onward. So myPlayer() is guaranteed non-null by the time tick() first runs for a real human player — false positive.

Well-decoupled implementation: the panel drives highlights purely over the EventBus (no direct references to ControlPanel/UnitDisplay), step completion is derived from real sim state rather than intents (so a rejected action can't fake progress), and i18n coverage for the new tutorial.* strings is complete with no other translation files touched.

After the city, walk the player through building a Port (on the
coastline) and then a Factory, using the same hotbar highlight +
press-hotkey pattern. Steps interpolate the player's actual keybind and
are skipped when the unit is disabled in the game config.

🤖 Claude Code Review

Verdict: ✅ No high-confidence issues found. Findings: 0 critical, 0 high, 0 medium, 0 low.

Review scope

Reviewed the full diff for PR #5221 (feat(client): add an in-game tutorial panel) across 10 changed files: index.html, resources/lang/en.json, src/client/hud/GameRenderer.ts, src/client/hud/layers/ControlPanel.ts, src/client/hud/layers/Tutorial.ts (new), src/client/hud/layers/TutorialPanel.ts (new), src/client/hud/layers/UnitDisplay.ts, src/client/styles.css, src/core/game/UserSettings.ts, tests/Tutorial.test.ts (new).

Checks performed:

  • CLAUDE.md compliance — i18n rule (translateText() + resources/lang/en.json entries, no other lang files touched): compliant. Determinism rule for src/core changes: the only src/core touch (UserSettings.ts) is a trivial boolean localStorage getter/setter pair (tutorialDismissed()/setTutorialDismissed()), matching the existing untested helpMessages()/toggleHelpMessages() precedent in the same file — not simulation/determinism logic, so this was not flagged as a violation.
  • Bugs / logic errors — traced the TutorialProgress state machine (Tutorial.ts) index/linger/applicability transitions against the new unit tests, verified all referenced APIs (PlayerView, GameView, Controller, EventBus events) resolve and type-check, checked drag-handler pointer math, hotkey fallback mapping, and step-counter math skipping inapplicable steps. No compile errors, no unresolved references, no clear logic errors found.
  • Security — all tutorial copy is rendered via translateText() as plain Lit text (no unsafeHTML/innerHTML), no user-controlled data is rendered by the panel. No XSS concerns.

One candidate issue (missing test coverage for the two new UserSettings.ts methods) was raised independently by two reviewers but rejected on validation: it follows a pre-existing, unremediated convention for trivial boolean settings wrappers in that file, and the code in question is client-side persistence rather than the deterministic simulation logic the CLAUDE.md rule is aimed at.

No blocking issues. Nice clean separation between pure step logic (Tutorial.ts, fully unit-tested) and the rendering component (TutorialPanel.ts).

… the map

Insert a capture-tribes step right after the first expansion: it explains
that conquering tribes earns gold, glows every living tribe on the map,
and stays up until the player can afford a City (replacing the separate
earn-city-gold step). The glow reuses SmallPlayerGlowPass through a new
GameView.setGlowingPlayers() set that WebGLFrameBuilder merges into the
small-player highlight set, exempt from that feature's spawn/grace gate.

🤖 Claude Code Review

Verdict: One medium-confidence issue found. Findings: 0 critical, 0 high, 1 medium, 0 low.

File: src/client/hud/layers/TutorialPanel.ts

Medium — capture_tribes step's "they're glowing on the map" cue silently does not appear when the player's glow-strength setting is 0. (syncTribeGlow, ~lines 519-533, plus src/client/WebGLFrameBuilder.ts ~lines 483-520)

The tutorial's tribe highlight is fed through the same pipeline as the existing small-player glow: TutorialPanel.syncTribeGlow() -> GameView.setGlowingPlayers() -> WebGLFrameBuilder.syncSmallPlayerGlow() -> MapRenderer.updateSmallPlayerGlow() -> SmallPlayerGlowPass.draw().

The WebGLFrameBuilder.ts rewrite explicitly hoists the tutorial's glow set above the spawn/grace-period gate (per its own new comment: "exempt from the spawn/grace gate"), but SmallPlayerGlowPass.draw() (src/client/render/gl/passes/SmallPlayerGlowPass.ts:168-169) still hard-gates on the user's "highlight glow strength" setting:

const strength = Math.min(1, this.settings.strength);
if (!this.active || strength <= 0) return;

This setting is user-configurable down to 0% (GLOW_STRENGTH_MIN = 0 in GraphicsSettingsModal.ts:81), and there is no exemption for the tutorial's set the way there is for the spawn/grace gate.

Failure scenario: a player who has turned "highlight glow strength" to 0% (e.g. for performance or visual preference) reaches the capture_tribes step. The panel shows tutorial.step.capture_tribes: "Capturing tribes is a great way to earn gold - they're glowing on the map. Conquer them until you have {cost} gold for a City." - but nothing actually glows, since the render pass returns before drawing anything. The step is long-running (it stays up until the player can afford a City), so the player is left looking for a visual cue that does not exist until they stumble onto the mechanic another way.

Suggested fix: either exempt the tutorial's glow set from the strength gate in SmallPlayerGlowPass.draw() (mirroring how it is already exempted from the spawn/grace gate), or force a minimum visible strength while gameView.glowingPlayers() is non-null.

Reviewed the full diff (12 files) across two independent CLAUDE.md-compliance passes and two independent bug passes (diff-only and introduced-code-focused), then validated the one candidate finding against the current code before including it here.

Two other candidate issues were raised internally and rejected after verification:

  • A claim that TutorialPanel.tick() permanently disables the tutorial after myPlayer() returns null or the player dies, with no path back. Traced the call chain (ClientGameRunner always runs gameView.update() before renderer.tick(), human PlayerViews exist from tick 0, isAlive() has no revive path in this game) - the only way player === null fires is for spectators/replays, and death is a terminal state by design, so treating both as permanent deactivation is correct, not a bug.
  • Missing test coverage for the new UserSettings.tutorialDismissed()/setTutorialDismissed() getter/setter pair (src/core/game/UserSettings.ts). This mirrors ~10 other structurally identical, already-untested boolean setting pairs in the same file (helpMessages/toggleHelpMessages, anonymousNames/toggleRandomName, etc.) - an existing, accepted convention rather than a new gap, so not flagged as a CLAUDE.md violation.

No CLAUDE.md compliance issues found (i18n via translateText()/en.json is complete and correct, no other language files touched; the only src/core change is the trivial, convention-matching settings pair above).

The tribe highlight rides the small-player glow pass, whose draw gates on
the user's "highlight glow strength" setting — at 0 the tutorial promised
a glow that never rendered. Thread a minStrength through
updateSmallPlayerGlow so the explicit (tutorial) set floors the strength
at the default while it's showing. Addresses the Claude review finding.

Review round addressed in ff1417d→HEAD:

  • Fixed (medium, TutorialPanel.ts/SmallPlayerGlowPass.ts): the capture-tribes step's map glow was invisible for players with "highlight glow strength" set to 0. updateSmallPlayerGlow now takes a minStrength that the frame builder sets to the default strength (0.35) whenever the explicit tutorial set is non-empty, flooring the user setting only while that set is showing. Verified in a headless game with smallPlayerGlow.strength = 0: tribes still render the aura, nations don't, and the small-player glow stays off otherwise.

Verdict: One medium-severity issue found. Findings: 0 critical, 1 medium, 0 minor.

Reviewed the current HEAD (which includes the fix from the prior review round for the tribe-glow-invisible-at-0-strength bug — confirmed present and correct). Checked CLAUDE.md compliance (i18n via translateText()/en.json, src/core determinism/testing rules) via two independent passes, and scanned for bugs via two independent passes (diff-only and introduced-code-focused), then validated the one candidate finding against the actual code before including it here.

src/client/hud/layers/Tutorial.ts

Medium — capture_tribes step is ordered too early in TUTORIAL_STEPS, blocking the troops, attack_bot, and gold tips behind a long, unrelated grind. (TUTORIAL_STEPS, lines ~306-333)

The tutorial is a strict one-step-at-a-time wizard (TutorialProgress advances index sequentially; only current() is ever rendered). The array order is:

spawn → attack_wilderness → capture_tribes → troops → attack_bot → gold → buy_city → buy_port → buy_factory

capture_tribes's own comment says it "stays up ... until the player has banked enough gold for the City step ahead," and its isDone only fires once cities > 0 || (cityCost !== null && gold >= cityCost) — i.e. it's a gate meant to sit immediately before buy_city, not three slots earlier. First-city cost is 125,000 gold (Config.ts) against ~100 gold/tick passive income, so this step alone takes roughly two minutes of real play to clear (confirmed against tests/Tutorial.test.ts, which hardcodes cityCost: 125_000n).

Because of the current placement:

  • The troops tip (regrouping/regrowing troops before re-attacking) — exactly the guidance a brand-new player needs in their first couple of minutes — is withheld until after that gold grind finishes.
  • The gold tip ("Gold builds up over time…") only appears after the player has already banked City-level gold, making it redundant.
  • attack_bot (isDone: c.attackingBot) becomes current only after capture_tribes already told the player to "Conquer them until you have {cost} gold for a City," so by the time attack_bot displays, an attack is typically already in flight and the step completes almost immediately — it's shown for a ~1.5s linger and effectively never read.

This also contradicts the flow stated in the PR description itself: "spawn → attack the wilderness → watch your troop count → attack a bot → learn about gold → save up for and build a City" (save-up-for-city is last, not third).

Suggested fix: move the capture_tribes entry to sit immediately before buy_city (i.e., after gold), matching both the PR's own description and the step's comment. Note tests/Tutorial.test.ts encodes the current order (e.g. asserts position(c) === 3 for troops) and will need its expectations updated alongside the reorder.

Review round for 995849b: 1 finding, declined.

  • Declined (medium, Tutorial.ts step ordering): placing capture_tribes immediately after the first expansion — and keeping it up until the player can afford a City — is a deliberate product decision, not a leftover: the step is meant to give brand-new players a concrete goal (capture the glowing tribes) during their first minutes, with the troops/bot/gold tips surfacing as they play through that stretch. The observation that the PR description described the older flow was fair; the description has been updated to match.

… tip

Glow only the three tribes nearest the player (by name location,
refreshed as they're captured) instead of every tribe, and draw the
tutorial glow at a fixed subtle strength (0.2) that overrides the
small-player slider rather than flooring it at the default. Move the
troop-count tip before the capture-tribes step so it lands before the
player starts fighting.

The pulsing ring alone was easy to miss on the small hotbar buttons.
Highlighted unit-display buttons now scale up 1.3x, get a gold border
and tinted fill, and a bobbing gold arrow points down at them. The
control panel's wide bars keep the subtle ring.

🤖 Claude Code Review

Verdict: One medium-severity issue found, plus one low-severity CLAUDE.md compliance note. Findings: 2 (1 medium, 1 low).

src/client/WebGLFrameBuilder.ts

[Medium] syncSmallPlayerGlow merges the tutorial's glow set with the normal small-player-glow set into one shared bitmask, then applies a single global strength override to the whole thing —

const set = this.highlightSetBuf;
set.fill(0);
let any = false;
let explicitAny = false;
for (const id of gameView.glowingPlayers() ?? []) {
set[id] = 1;
any = true;
explicitAny = true;
}
// Strength (incl. off at 0) is read live in the glow pass; here we only
// decide who qualifies. Skip spawn + the first minute.
if (
!gameView.inSpawnPhase() &&
gameView.elapsedGameSeconds() >= SMALL_PLAYER_GLOW_GRACE_SECONDS
) {
// "% of the map" uses the same denominator the leaderboard/win-check use.
const denom = gameView.numLandTiles() - gameView.numTilesWithFallout();
for (const p of denom > 0 ? gameView.players() : []) {
if (!p.isPlayer() || p.type() !== PlayerType.Human || !p.isAlive()) {
continue;
}
if (p.numTilesOwned() / denom <= SMALL_PLAYER_MAX_MAP_FRACTION) {
set[p.smallID()] = 1;
any = true;
}
}
}
this.view.updateSmallPlayerGlow(
any ? set : null,
explicitAny ? EXPLICIT_GLOW_STRENGTH : null,
);

syncSmallPlayerGlow writes both the tutorial's explicit glow IDs (gameView.glowingPlayers()) and the qualifying small human players into the same Uint8Array (set), with no way to tell afterwards which bit came from which source. It then calls:

this.view.updateSmallPlayerGlow(
  any ? set : null,
  explicitAny ? EXPLICIT_GLOW_STRENGTH : null,
);

explicitAny is a single flag for "any tutorial players present," and this one strengthOverride value flows straight through to SmallPlayerGlowPass.draw() (src/client/render/gl/passes/SmallPlayerGlowPass.ts#L176-L179), where it's used as one uniform for the entire draw call — there's no per-player strength; extract.frag.glsl just treats the mask as a boolean.

Net effect: whenever the tutorial's capture_tribes step is glowing at least one tribe, every genuinely-small human player who separately qualifies for the small-player-glow feature also gets forced to render at the fixed EXPLICIT_GLOW_STRENGTH (0.2) — including players whose own smallPlayerGlow.strength setting is 0 (i.e. the feature is off for them). This silently overrides the user's own setting for players the tutorial was never meant to affect, for as long as that tutorial step is active.

Suggested fix: keep the tutorial-glow set and the small-player-glow set as two separate draws/uniforms (or thread a per-player strength array instead of a single scalar), so EXPLICIT_GLOW_STRENGTH only ever affects the IDs that came from gameView.glowingPlayers(), not the ones added by the small-player scan.

src/core/game/UserSettings.ts

[Low] New tutorialDismissed()/setTutorialDismissed() methods have no test coverage —

tutorialDismissed() {
return this.getBool("settings.tutorialDismissed", false);
}
setTutorialDismissed(value: boolean) {
this.setBool("settings.tutorialDismissed", value);
}

Root CLAUDE.md states unconditionally under src/core/: "All src/core changes must include tests." This PR adds a new boolean getter/setter pair here with no corresponding test in tests/UserSettings.test.ts (or anywhere else). Note this mirrors an existing gap — the pre-existing helpMessages()/toggleHelpMessages() pair in the same file is likewise untested — so this isn't a new pattern, but the CLAUDE.md rule itself is unqualified.

Suggested fix: add a small test to tests/UserSettings.test.ts covering the default (false) and persistence of tutorialDismissed()/setTutorialDismissed(), consistent with the "all src/core changes must include tests" rule — optionally also backfilling helpMessages while there.

While the tutorial's explicit glow set was showing, the small-player
scan merged into the same bitmask and the single strength uniform forced
the fixed tutorial strength onto qualifying small players — overriding
their user setting (including off). The pass draws one set at one
strength, so skip the small-player scan while the explicit set is
active; it resumes as soon as the tribes step ends. Also add the
UserSettings tutorialDismissed test the review asked for.

Review round for e4bd913: 2 findings, both fixed in the follow-up commit.

  • Fixed (medium, WebGLFrameBuilder.ts): the tutorial's glow set and the small-player-glow set merged into one bitmask drawn at one strength, so while tribes were glowing, qualifying small human players were also forced to the fixed tutorial strength (overriding their slider, including off). The pass draws a single set at a single strength, so the small-player scan is now skipped while the explicit set is showing — the tutorial set renders alone at its fixed strength, and the small-player glow resumes (at the user's setting) the moment the tribes step ends.
  • Fixed (low, tests/UserSettings.test.ts): added coverage for tutorialDismissed()/setTutorialDismissed() (default false, persistence, un-dismiss), per the CLAUDE.md src/core testing rule.

🤖 Claude Code Review

Verdict: No blocking issues found. Findings: 0 critical, 0 major, 0 minor.

Reviewed the full diff for CLAUDE.md compliance (i18n via translateText()/en.json, no edits to other translation files, src/core test-coverage rule, and the src/client/render/ pass conventions) and for bugs/logic/security issues, using two independent CLAUDE.md-compliance passes and two independent bug/security passes, all working from the diff and surrounding code.

CLAUDE.md compliance — clean:

  • Every new tutorial.* / referenced unit_type.* string in TutorialPanel.ts is routed through translateText() with a matching key added to resources/lang/en.json; no other locale file under resources/lang/ is touched.
  • The only src/core change (src/core/game/UserSettings.ts: tutorialDismissed() / setTutorialDismissed()) has corresponding coverage in tests/UserSettings.test.ts.
  • The strengthOverride plumbing added to MapRenderer.tsRenderer.tsSmallPlayerGlowPass.ts only extends the existing setter chain; SmallPlayerGlowPass still consumes pushed data only (no direct DOM/game-state reads), and no new pass was added, so the render-directory's pass-registration checklist doesn't apply.

Bugs / logic / security — clean:

  • TutorialProgress step-advance, linger, skip, and position()/total() bounds logic in Tutorial.ts were traced by hand against tests/Tutorial.test.ts and hold up.
  • Drag/clamp math, pointer-capture handling, and keybind fallback interpolation in TutorialPanel.ts check out.
  • No innerHTML/unsafeHTML usage — all rendered text goes through translateText() via Lit's auto-escaping text bindings.
  • Tribe-glow and HUD-highlight state is cleared on every deactivation path (manual close, death/replay bail-out, dismissForever()), and strengthOverride is assigned before the set === null early return in WebGLFrameBuilder.syncSmallPlayerGlow, so it can't go stale.

Nice, well-decoupled implementation overall — pure/testable TutorialProgress model, state-driven (not intent-driven) step progression so a rejected action can't falsely advance the tutorial, and full i18n coverage for new strings.

(Two minor, non-blocking observations for the author, not filed as findings: the PR description references an "attack a bot" step that isn't in the implemented step list — the closest is capture_tribes — and describes the tribe glow strength as "floored to the default strength" when the code actually pins it to a fixed EXPLICIT_GLOW_STRENGTH = 0.2. Neither affects correctness.)

Move the panel from the draggable top-right position into the bottom
HUD column, between the attacks display and the control panel, and drop
the drag machinery — it's a normal in-flow card now.

@evanpelle evanpelle added this to the v34 milestone Sep 2, 2026
Replace the map glow on nearby tribes with the game's existing target
crosshair: GameView.setMarkedPlayers() ORs the tutorial's set into the
isTransitiveTarget predicate feeding the name pass, so marked tribes
render exactly like targeted players. The SmallPlayerGlowPass /
Renderer / MapRenderer / WebGLFrameBuilder glow plumbing reverts to
main. Also move Got it / Skip into the panel header and tighten padding
so the docked panel takes less vertical space.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Names and their status icons cull below a screen-size threshold, which
hid the target crosshair (and the tutorial's tribe marks) when zoomed
out. Targeted players now bypass the cull in the name and status-icon
shaders, boosted to the smallest size that survives it — same idea as
the existing hovered-name bypass, driven by the target flag already in
the player-data texture.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
After building the City, mark the nearest nation with the target
crosshair and ask the player to right-click it and propose an alliance;
the step completes when the nation accepts (Skip covers declines). A
follow-up "Got it" stop explains that breaking an alliance marks you as
a traitor. The tribe-marker logic generalizes into a per-target
map-marker spec (tribes: 3 nearest bots, nation: nearest nation). Both
steps are skipped when no nations exist or alliances are disabled.

🤖 Claude Code Review

Verdict: Approve with suggestions — 3 findings, all medium/low severity, none blocking. Findings: 0 critical, 0 high, 2 medium, 1 low.

File: src/client/render/gl/shaders/name/icon.vert.glsl (and status-icon.vert.glsl) — Medium

What's wrong: The new cull-bypass for "targeted" players was added to name.vert.glsl (lines 104–123) and status-icon.vert.glsl (lines 162–168), but the third pass in the same status row — icon.vert.glsl, which draws the flag (iconType == 0) and emoji (iconType == 1) — was not updated and still culls unconditionally against uCullThreshold (icon.vert.glsl:87-97).

status-icon.vert.glsl's row-centering math (totalItems = totalActive + (hasEmoji ? 1 : 0), ~lines 190–203) lays out the status-icon row assuming the emoji slot will be drawn whenever pd4.y >= 0.0 (an emoji is assigned) — but for a targeted player below the cull threshold, icon.vert.glsl still discards that emoji quad (and the flag quad), since it has no target-aware bypass. Result: the status-icon row is visibly shifted/off-center when a targeted, zoomed-out player has an active emoji, and that player's flag disappears entirely even though their name and status icons are boosted into visibility — contradicting the "boosted in lockstep" comments added in this PR.

This isn't tutorial-only: it triggers for any player carrying the pre-existing target status flag (see next finding), so it's reachable in normal gameplay whenever someone marks a target and zooms out.

Suggested fix: Add the same pd6.y > 0.5 (target flag) cull-bypass block to icon.vert.glsl that was added to the other two shaders, so all three passes stay in lockstep.

File: src/client/render/gl/shaders/name/name.vert.glsl:104-123, status-icon.vert.glsl:162-168, src/client/view/GameView.ts:599-601 — Medium

What's wrong: GameView.setMarkedPlayers() is OR'd directly into the existing isTransitiveTarget callback (GameView.ts:599-601), which is the same signal the shaders' target status flag (pd6.y / statusFlag[5]) is built from. The new cull-bypass in name.vert.glsl/status-icon.vert.glsl is keyed off that generic target flag, not a tutorial-specific one — so this "always render at legible size regardless of zoom" behavior now applies to every player who is a transitive target for any reason (a real attack/build target the player or an ally/teammate marked), not just tutorial-marked tribes. This is an unscoped rendering-behavior change for all game modes, shipped inside a tutorial-only PR, with no test coverage and no mention in the PR description.

To be fair: the effect is transient (targetDuration is ~10s per Config.targetDuration()), and reusing the existing "target crosshair stays findable" mechanism is arguably coherent with its original intent — so this is more a scope/disclosure concern than a correctness bug. Worth confirming with the author whether it's intentional; if not, the tutorial marks should get their own status flag bit rather than reusing target.

Suggested fix: Either explicitly call out this behavior change in the PR description, or give tutorial map-marks a dedicated flag/uniform so the cull-bypass doesn't affect ordinary transitive-target rendering.

File: src/client/hud/layers/Tutorial.ts:92,109,114,221-227 and src/client/hud/layers/TutorialPanel.ts:171-176,243-247 — Low

What's wrong: TutorialProgress.position()/total() recompute the applicable-step count against the live context on every render (Tutorial.ts:221-227, via applicable()), rather than a snapshot taken once. Three steps' applies predicates depend on live, monotonically-decreasing state — capture_tribes on botsExist (Tutorial.ts:92) and propose_alliance/alliance_info on nationsExist (Tutorial.ts:109,114) — both rebuilt fresh every tick in TutorialPanel.buildContext() (TutorialPanel.ts:171-176) from playerViews().some(...isAlive()).

Since bots/nations can only go from alive to dead (never back), a player parked on an unrelated step (e.g. buy_factory) can watch the header counter regress — e.g. "Step 8 of 17" shrinking to "Step 6 of 15" — purely because the last bot or nation died elsewhere on the map, with no action or skip on the player's part.

Suggested fix: Snapshot the applicable-step set (or just the botsExist/nationsExist values used for counting) once, e.g. on the first update() call, and use that fixed snapshot for position()/total(), while continuing to use the live context for the skip/isDone progression logic.


CLAUDE.md compliance was also checked (i18n via translateText()/en.json, src/core test coverage and determinism for the UserSettings.tutorialDismissed addition, and src/client/render/CLAUDE.md conventions for the two shader files) — no violations found.

Give icon.vert.glsl (flag/emoji pass) the same targeted-player cull
bypass as the name and status-icon shaders so a targeted player's whole
name row renders in lockstep when zoomed out. Freeze the tutorial's
"Step n of N" counter on the first post-spawn context so bots/nations
dying mid-game can't shrink it; progression still uses live state.

Review round for 715e543: 2 fixed, 1 partially declined.

  • Fixed (medium, icon.vert.glsl): the flag/emoji pass now has the same targeted-player cull bypass + boost as the name and status-icon shaders, so the whole name row stays aligned for targeted players when zoomed out.
  • Fixed (low, Tutorial.ts): position()/total() now use a context snapshot taken on the first post-spawn update (when bots/nations all exist), so the "Step n of N" counter can't shrink when the last bot or nation dies mid-game; skipping/isDone progression still uses the live context.
  • Partially declined (medium, target-flag scope): applying "always visible at any zoom" to all transitive targets — not just tutorial marks — is intentional, per the author's direction that a targeted player's name should always be visible. The disclosure half of the finding was fair: the PR description now calls out the general behavior change explicitly.

🤖 Claude Code Review

Verdict: Approve with one medium-confidence issue found. Findings: 0 high, 1 medium, 0 low.

src/client/hud/layers/TutorialPanel.ts

Medium — syncMapMarkers permanently blacklists a nation once its cached relation dips below Neutral, so it can never be re-marked even after the relation recovers (src/client/hud/layers/TutorialPanel.ts:166-178)

const picked =
  spec.type === PlayerType.Nation
    ? candidates.filter(
        (c) =>
          (this.nationRelations.get(c.id) ?? Relation.Neutral) >=
          Relation.Neutral,
      )
    : candidates;
if (spec.type === PlayerType.Nation) {
  this.fetchNationRelations(picked.slice(0, 5).map((c) => c.id));
}

fetchNationRelations is the only writer of this.nationRelations, and it only refreshes the ids it's called with. Since it's fed picked (the post-filter list) rather than candidates (the pre-filter list), any nation whose cached relation ever drops below Relation.Neutral is excluded from picked — which means it's excluded from every future fetchNationRelations call too. The cache for that nation can never be updated again, even though PlayerImpl.decayRelations() (src/core/execution/PlayerExecution.ts) pulls real relations back toward Neutral every tick in the live sim.

This is reachable within a normal tutorial run: the tutorial's own earlier steps (earn_gold, capture_tribes, buy_warship) actively encourage attacking/raiding neighbors, which are exactly the actions (AttackExecution, NationWarshipBehavior, NationEmojiBehavior, TargetPlayerExecution) that push a nearby nation's relation negative. A single blip below Neutral — even one that self-heals in 15–20 seconds — permanently removes that nation from marker eligibility for the rest of the panel's lifetime (there's no TTL or reset). Since propose_alliance comes right after those steps in TUTORIAL_STEPS, nearby nations can all be ratcheted out by the time the player reaches it, leaving setMarkedPlayers(new Set()) (no target) while the step text still says "Right-click the nation marked with a target and propose an alliance" — a dead instruction recoverable only via Skip, even though genuinely-Neutral-again nations exist and would be accepted by NationAllianceBehavior.

Suggested fix: fetch relations from the pre-filter list so the cache keeps refreshing for nearby nations regardless of their last-known state:

if (spec.type === PlayerType.Nation) {
  this.fetchNationRelations(candidates.slice(0, 5).map((c) => c.id));
}

🤖 Generated with Claude Code

The ally-step marker fetched relation updates only for nations that
passed the neutral-or-friendly filter, permanently blacklisting any
nation whose cached relation ever dipped below neutral — even though
relations decay back toward neutral in the sim. Fetch from the
pre-filter candidate list instead. Addresses the Claude review finding.

  • Fixed (medium, TutorialPanel.ts): the ally-step relation cache was only refreshed for nations that passed the neutral-or-friendly filter, so one dip below neutral blacklisted a nation permanently even after its relation decayed back.

  • src/core rule: the only core change (UserSettings.tutorialDismissed()/setTutorialDismissed()) is non-deterministic-math-free localStorage plumbing, and is covered by tests in tests/UserSettings.test.ts.
  • src/client/render/CLAUDE.md scope: only the three vertex shaders were touched (no pass .ts files); the zoom-cull bypass reads the existing uPlayerData texture the same way existing highlight/owner checks do, and the target flag index (ivec2(6, playerIdx).y / statusFlag[5]) was verified against the data-texture packing in DataTextures.ts.
  • Logic: TutorialProgress step advancement, linger, skip/acknowledge, and the fixed countCtx snapshot for "Step n of N" were traced against tests/Tutorial.test.ts and hold up; keybind fallbacks match UnitDisplay.ts; no XSS vectors (all Lit text bindings, no innerHTML/unsafeHTML).

A couple of very low-confidence, non-blocking observations came up during review (not filed as findings since they don't meet the bar for this checklist):

  • TutorialPanel.ts (~line 641): player.buildables(...).then(...) has no .catch, so a rejected worker call would be an unhandled promise rejection.
  • TutorialPanel.ts (~line 100-107): player === null is bundled with the death/replay cases that permanently deactivate the tutorial via setActive(false); likely unreachable given _myPlayer is resolved before tick() ever runs, per GameRenderer.

Note: the PR description mentions tribe highlighting is implemented "by reusing SmallPlayerGlowPass through GameView.setGlowingPlayers()" — the actual diff implements this via GameView.setMarkedPlayers() reusing the existing target-crosshair (isTransitiveTarget) mechanism instead. Worth a description update, but not a code issue.
