[Vatsal2005]

What and why

Hold Act to raise the chair and block frontal one-cell damage. Guard becomes active at the first forward-leg pose (02), loops the hold clip, and plays impact poses with a 14px kinematic push on a successful block. A blocked rover recoils without losing HP, preventing the charge from passing through into a back hit. Rear damage still hits normally.

Two-cell heavy damage breaks the guard and uses normal life damage/knockback. The four break poses survive the knockback state; death takes priority. A quick release remains a sweep, an engaged release consumes the input, and a hold begun during another attack raises guard when that attack finishes. Directional attacks keep priority.

Acceptance and remaining integration

• Held Act blocks frontal damage with a small push; verified against the real tutorial rover

• Rear hits cost health despite holding guard

• Two-cell heavy damage breaks guard and plays four authored break poses; verified in the pure guard/life test

• Actual Jenny charge integration and browser playthrough when [M4-S5] Jenny: rev, charge, crash, debris, stunned – three phases #57 reaches this stack

Verification

• Node 22: npm run typecheck, npm test (128 tests), npm run build; includes main integration at e8577ab

• py -3.13 scripts/check_docs.py

• git diff --cached --check

• Tests cover exact pose/FPS activation, hold loop, quick versus engaged release, cancelled taps, front/back in both directions, blocked rover recoil without HP loss, heavy guard break, 14px push over three frames and wall clipping

• Browser: holding J through the first real rover charge leaves 5/5 cells, increments the block counter to 1 and moves the hero from x676 to x662 (14px). Rover remains at 3/3 HP

• Browser: facing away while holding J takes a rear charge, leaves 4/5 cells and records zero blocks

• Browser: a 5ms tap followed by a long hold leaves one fixture hit; guard release adds no sweep. No console errors

• Physical gamepad and Vercel preview: existing deployments require the owner to grant Vatsal2005 project access

Reference comparison

Plan: docs/02 chair guard.

Reproduce: python scripts/compare.py lineup chair-block:guard-up-00 chair-block:guard-up-01 chair-block:guard-up-02 chair-block:guard-up-03 chair-block:guard-hold-00 chair-block:guard-impact-00 chair-block:guard-break-00 --out game/verification/41-guard-pose-compare.png.

Pose 02 is the first raised pose with forward-pointing legs, so activation is 2/12s. Standing raise/hold poses measure 76px; the approved impact crouches to 72px and break extends to 92px including the raised arms. Runtime preserves native atlas sizes. Push distance is half the documented 28px body width and uses the existing wall/floor solver.

Browser proof shown in chat and retained in ignored tmp/verification/41-front-guard.png, 41-rear-hit.png and 41-tap-then-hold.png. The front capture is after the block/release and before the next unguarded charge; its persistent block counter and unchanged five cells identify the successful block.

Short-tap correction

The pool integration check exposed a lost-tap case: Phaser's Key.onUp clears the press flag, so a complete tap between rendered frames can leave only the release flag. Guard routing now reconstructs that tap when no down state was observed. A held guard release stays a release and does not restart an attack.

The regression test routes that exact key state through the real guard and sweep models into a rover contact. Node 22 typecheck, 128 tests, build and docs pass. In the browser, two separate 5ms taps both connect and the fixture records two hits without console errors (tmp/verification/41-retained-short-taps.png, shown in chat).
