[Vatsal2005]

What and why

Press Up/W or gamepad Up while grounded at a coffee machine to drink, refill all five cells and save the current foot position. The authored three-frame interact clip owns input for a quarter second; a held direction never repeats the save. Death returns to the new checkpoint with full health.

The real Rusty Creek machine is located through its collision annotation and chunk offset. Until lane A exports mensa-drinks, its atlas placeholder occupies the exact 40×80 box and flickers for one 12fps frame every two seconds. An explicit pending-art loader avoids requesting an absent real atlas. Checkpoints now copy position fields only.

Closes #43

Base: feature/39-chair-sweeps. Human merges bottom up; retarget the next PR to main and merge origin/main into every open branch, never rebase.

Acceptance criteria

• Up at the machine: drink, save, refill all cells
• Respawn point updates; the machine flickers while idle

Verification

• Node 22: npm run typecheck, npm test (108 tests), npm run build; includes main integration at e8577ab
• py -3.13 scripts/check_docs.py
• git diff --cached --check
• Real-file tests check the authored box, translated coordinates and approved drink metadata. Interaction tests cover edge triggering, entering with Up held, ineligible/air rejection, quarter-second input ownership, damage cancellation, refill and checkpoint copy followed by death/respawn. Flicker tests check the one-frame window.
• Browser: damaged from five to four cells, walked back into the real machine and pressed Up; HUD returned to five. Then two heavy hits and one lethal normal hit returned the hero to the saved x=3968.7, y=537 with five cells. No console errors.
• Physical gamepad and Vercel preview. Existing deployments require Vatsal2005 to be granted project access by the Vercel owner.

Reference comparison

Plan: docs/02 coffee save.

Made with python scripts/compare.py images art/stages/rusty-creek/collision/rc-1-0.anomaly.png@870,218,50,60 tmp/verification/43-coffee-respawn.png@573,338,78,93 --width 400 --grid 40 --out game/verification/43-coffee-box-compare.png. The annotation preview is half stage scale and the browser is fitted to the viewport; both crops cover the same roughly 100×120 stage-pixel area, shown at 4× for review. Exact 40×80 bounds are asserted by real-file tests. White is the hero body; purple is the coffee interaction box.

Made with python scripts/compare.py lineup hero-hurt:interact-00 hero-hurt:interact-01 hero-hurt:interact-02 --out game/verification/43-drink-pose-compare.png. The approved leaning poses measure 72px high against the 76px standing reference; runtime preserves them without scaling.

Full browser proof shown in chat and retained in ignored tmp/verification/43-coffee-refill.png and 43-coffee-respawn.png. The coffee-test development URL starts at the real authored machine without copying or moving collision data.

Scope and art hand-over

This saves the running game's death checkpoint, consistent with the existing life state. Disk persistence is not part of #43. Real idle/flicker/pour atlas integration follows the pending mensa-drinks export in #84. No art, collision annotations, shared event payloads or lane A files changed.
