[Vatsal2005]

What and why

The hero has five cells, one-cell normal damage and two-cell heavy damage, white flash, 64.5px knockback and one second of invulnerability with flicker. Death plays the supplied collapse clip and pixel dust, then restores full health at the checkpoint. Orange hazards damage and reset to safe ground; black no-go regions reset without damage. Actors can register respawn callbacks; defeated boss ids survive scene restarts. The public checkpoint/healing hooks are ready for coffee and food interactions.

Closes #42

Base: feature/31-animation-state-machine. Human merges bottom up; retarget the next PR to main and merge origin/main into every open branch, never rebase.

Acceptance criteria

• Five cells, normal damage 1 and heavy charge damage 2
• White flash, about 1.5m knockback, one-second invulnerability and flicker
• Collapse/dust and full-health checkpoint respawn; normal actor reset callbacks and persistent defeated bosses
• Hazard damage and safe-ground reset; no-go reset is free

Verification

• Node 22: npm run typecheck, npm test (93 tests), npm run build; includes main integration at e8577ab
• py -3.13 scripts/check_docs.py — 650 files
• git diff --cached --check
• Pure tests cover costs, immunity duration, both knockback directions, checkpoint copies, full-health respawn, actor resets, defeated-boss protection, hazard/no-go reset semantics and healing cap
• Browser: 1-cell hit moved x=90 to x=154.5; immediate second hit ignored; heavy hit costs 2; hazard costs 1 and no-go costs 0
• Browser: death clip then respawn at x=90 with all five actual battery sprites restored; no console errors
• Browser: stepped off the real first Creek deck into its authored no-go area; returned to last safe x=438.1 with all five cells, rather than the entry spawn
• Actual coffee activation follows [M2-S5] Coffee machine save point #43; real rover contact/defeat reset follows [M2-S6] Rover: patrol, spot, charge #45, and defeated Jenny stays dead after [M4-S5] Jenny: rev, charge, crash, debris, stunned – three phases #57. The checkpoint and actor-registry behavior is tested here.
• Vercel preview: GitHub states Vatsal2005 needs project access on Vercel to create deployments. A project owner must grant access; local checks pass.

Integration

The six agreed event payloads remain intact. Hit/death/save use the existing bus; healing and respawn update the HUD through its public model API. Development F5 exercises a hit, Shift+F5 heavy damage, Ctrl+F5 a hazard reset and Alt+F5 a free reset. F5 is captured by the game and these controls are omitted from production. Attacking is locked while dead, knocked back or climbing.
