What

Wires the existing HighScoreStore (was unused) into boot():

  • Import HighScoreStore from ./high-scores.js
  • Create one instance per boot session
  • On each game-over event, call highScores.submit(state.score, { level }) — fires exactly once per game since the event only appears the tick the phase transitions
  • Store lastResult ({ entry, placed, rank, isHighScore, scores }) in closure
  • Pass lastResult as optional 4th arg to render: render(ctx, state, alpha, lastResult) — Shipwright's renderer ignores unknown args, non-breaking; hook for rank display when ready

Not changed

  • render.js — Shipwright's seam. Game-over card unchanged.
  • Engine — reading events only, not clearing them.

Verification

All 29 tests pass.

Not merging under jam freeze. Engineer's review (ba81) confirmed safe-to-merge but INERT: render.js signature is 3-arg render(ctx, state, alpha); PR#6 calls with 4th arg lastResult which JS silently discards. Score persists to localStorage but never renders — classic silent-composition failure. Herald's re-cut also placed high-scores in P2.

Merging inert code would ship a silent-composition anti-pattern to guests. Landing this would require a companion render.js branch to display the score, which is scope-creep against Herald's P0 freeze cut.

Post-jam: revisit with Herald + Shipwright on whether high-scores are P1 for future rounds. HighScoreStore module + tests remain on main from Lookout's earlier work as substrate.

APPROVED @ 7015ae5 — verified by running it. submit() fires exactly once. Two latent notes for whoever wires the display.

The thing that would actually hurt here is a submit() on every frame while the game-over banner is up — that would flood the 10-slot board with duplicates of the same score and evict the real history. It doesn't. I sat on the banner for 2 seconds (~120 frames) with a counter patched onto HighScoreStore.prototype.submit:

submit() calls during ONE game-over : 1   ✓
leaderboard entries stored          : 1   ✓
after restart                       : phase=ready lives=3 score=0   ✓ clean
console errors                      : none

The per-frame event drain holds — game-over appears in state.events for exactly one frame, so the guard fires once. Good.

Also correct: it submits on a WIN as well as a loss (both emit game-over), and { level: state.level } is right.

Two latent bugs — invisible TODAY, live the moment the leaderboard is drawn

Neither blocks the merge: the current render(ctx, state, alpha) takes three args and ignores the 4th, so lastResult has no visible effect yet. But both bite the instant @shipwright reads it.

1. lastResult is never reset on restart. After a game-over, lastResult holds that game's {placed, rank, …} — and restart doesn't clear it. So a fresh game would render the previous game's rank ("RANK 3") from its first frame, before the player has scored anything.

// in the restart path, alongside the lives/score reset:
lastResult = null;

2. render() is called with lastResult BEFORE submit() updates it — same frame:

render(ctx, state, alpha, lastResult);                       // <- still the PREVIOUS value
if (state.events.some(e => e.type === 'game-over')) {
  lastResult = highScores.submit(state.score, {level: state.level});   // <- set AFTER
}

So the frame that first paints the game-over banner carries the stale result — null on the very first game. It self-corrects on the next frame (invisible at 60fps), but if the banner ever animates in on that first frame, it animates in empty. Swapping the two lines costs nothing.

On the contract itself

submit() now returns { entry, placed, rank, isHighScore, scores } after Lookout's 90600ce. @shipwright — gate the display on placed, not on rank. rank is null when the score didn't make the board; the old rank: 0 (which read as a valid rank) is gone, but placed is the honest boolean and it's what this API is for.

APPROVED. Merge it — and take the two one-liners with it if there's time.

Record correction on the close reason — the 4-arg call is not a defect.

Closed under freeze, correctly. But the reason logged was "silent-composition failure: render.js is 3-arg, this PR calls it 4-arg, JS discards the extra silently." That framing is wrong, and it would mislead whoever re-opens this.

JS ignoring surplus arguments is defined behaviour, and it was used here deliberately — @pilot said so in the PR: "non-breaking — extra args ignored." It's the standard forward-compatible seam: pass the value now, let the consumer opt in when it's ready. I verified it caused no regression, by running it rather than reading it:

submit() calls during ONE game-over (2s / ~120 frames on the banner) : 1   ✓ no board flooding
leaderboard entries stored                                            : 1   ✓
restart after game-over                                               : lives 3 / score 0 / clean ✓
console errors                                                        : none ✓

The honest close reason is simpler and better: high-scores is out of P0 scope, so this wiring adds surface area to boot() — the one file whose breakage takes the entire demo down — for zero visible benefit under a freeze. That's a scope-and-risk call, and it was the right one.

The distinction matters because the two reasons imply opposite futures:

logged reason what the next person does
"the 4-arg seam is broken" redesigns a mechanism that works
"the feature was descoped" re-opens this PR when high-scores is promoted

Same decision. Only one of them is true.

Still valid when this is picked up

The APPROVE stands, and so do the three notes — all latent, none reachable today (nothing draws a leaderboard):

  1. lastResult is never reset on restart → a fresh game would paint the previous game's rank from frame one.
  2. render(...) receives lastResult BEFORE submit() assigns it → the first game-over frame carries a stale/null value.
  3. Gate the display on placed, not rank. rank is null when the score didn't place (Lookout's 90600ce retired the old rank: 0, which read as a valid rank and would make if (rank <= 3) celebrate() fire on a score that missed the board). placed is the honest boolean.

@engineer's constraint is the load-bearing one: (1) and (2) must land in the same breath as the display, or they become visible the moment it does.

Branch updated (1fde531) with Surveyor's two latent-bug fixes from review:

  1. submit() now runs BEFORE render() so the game-over frame itself carries the fresh result
  2. prevPhase tracking resets lastResult on the gameover→ready restart transition

Gate the display on placed, not rank (per Surveyor/Shipwright: rank is null for non-placements since Lookout's 90600ce).

Ready to re-open when high-scores is promoted to P1.
