[Vatsal2005]

What and why

Up plus Act now selects the six-pose overhead attack, with contact only on poses 02/03. Airborne Down plus Act winds up, descends with the chair and bounces off a living enemy or hazard using the full jump impulse. A swept tip probe prevents thin-target tunnelling. Pogo recovery buffers one directional press; plain-floor landing, damage and death clear it.

Special input takes priority over climbing and coffee. Accepted hits retain the existing spark, sound and 60ms stop; enemy contact resolves after the chair so a pogo can snap to the target top before body damage. Defeated wrecks are excluded. Plain floors play the remaining slam poses without adding a crack or shockwave.

Acceptance and remaining playthrough

• Up + Act selects up attack
• Airborne Down + Act slams; enemy and hazard contacts produce pogo
• Tests perform three fresh pogos against the three-health rover model and strike a 40px crab fixture through its authored one-way deck
• Browser: four successive slam hits and bounces on the stationary rover fixture, one initial Jump press and five cells retained; the explicit slam 4 counter distinguishes these from sweeps
• Full moving tutorial rover clear and actual crab through-deck playthrough when [M2-S7] Crab: creep, rear, stab #46 is integrated. The moving-rover attempt did not clear and is not reported as complete
• Browser hazard fixture, physical gamepad and Vercel preview

Verification

• Node 22: npm run typecheck, npm test (119 tests), npm run build; includes main integration at e8577ab
• py -3.13 scripts/check_docs.py
• git diff --cached --check
• Unit coverage: actual clip metadata, exact contact bounds in both directions, active pose windows, one strike per target, three rover pogos, full 95–97px bounce without Jump held, thin hazards, rising rejection, wreck exclusion, armour bounce, input buffer/cancellation and plain-floor recovery
• Browser Up + Act beside the real coffee machine renders up-04 while feet stay grounded; the four-pogo fixture shows pogo-00 and hits 4 | slam 4. No console errors
• Existing Vercel deployments require Vatsal2005 to be granted project access by the owner

Reference comparison

Plan and mask measurements: docs/02 overhead attacks.

Reproduce: python scripts/compare.py lineup chair-overhead:up-02 chair-overhead:up-03 chair-overhead:slam-03 chair-overhead:slam-04 chair-overhead:pogo-00 chair-overhead:pogo-02 --out game/verification/40-overhead-pose-compare.png.

The atlas cell is 108×126 with foot pivot 54,126. Dark chair-leg pixels in up-03 occupy x51–78/y12–37: the contact envelope is x−3…24 and 89…114px above the feet. Slam-03 lower legs span x65–91, giving 11…37px forward. The downward probe sweeps previous/current feet with a two-pixel grain margin. Runtime preserves native pose sizes; the ruler is 13px/foot. The chair extends beyond the 76px body in overhead poses.

Browser evidence shown in chat and saved in ignored tmp/verification/40-counted-pogos.png and 40-up-at-coffee.png. The live repeated-pogo check uses the pre-existing stationary combat-test fixture, not a completed moving-rover clear. No art or collision annotations changed.
