Secret Slide original castle entrance - VERIFIED 2026-10-25

Verified scope: original title/File A -> castle exterior1 -> lobby2 -> one-Star
side door -> character room50 -> Peach window -> Secret Slide29. Existing
isolated two-Star Mario QA save, normal controller inputs, native game rules.
No development level picker, teleport, forced state or edited save used.
This does not establish fresh-save character progression or full slide completion.

Fix: only private replay waypoints changed. The old eastward approach drifted
outside the window aperture. Original playroom collision has a sill at766.7/770
(room floor600), an inner opening roughly300 units wide, and diagonal wall normal
(-0.707,0,-0.707). Approach now passes(2000,600,-1800), then(2100,600,-1700),
then jumps toward(2350,-1450), lining up before takeoff and passing the exit.
Game source/physics/collision/door/exit behavior and executable unchanged.
The prior key-door/upper-floor route and door-freeze interpretation are obsolete.

Ends8500 alive/grounded/Wait with normal control and stable position on starting
platform; total Stars remains2. Both disk saves match seed byte-for-byte.
Process exit0; native mixer errors0; output muted with zero nonzero device samples.
Screenshot6500 shows entry window;7000 shows Mario at the slide start. Both
visually inspected and displayed in chat. No audio was played during testing.

Build-current-route-check-20261025.cmd: Ninja no work; all7 focused CTests pass
(clock/input/input state/history/session/stage graph/collision).
work/check-castle-secret-slide-entry-20261025.py PASS; case entrance-acceptance.json.
It checks actual level sequence, normal control, stable final position, exact
EXE hash, unchanged saves, muted clean exit and available post-entry screenshots.
Only one new runtime attempt was needed after geometric measurement this turn.
Earlier two failed window cases remain negative evidence, not relabelled passes.

Next bounded task: test leaving Secret Slide via the original menu and re-entering
through this accepted route, checking restored control/resources. Luna Medium is
suitable for that replay lifecycle check. The existing lifecycle helper only
recognizes castle levels2/4, so first inspect actual return level; if it returns50,
handle that explicitly rather than feeding an inappropriate lobby route.
Full slide descent/box/Star/save/repeat tests from development selection remain
separate prior evidence. Timer/finish HUD, Yoshi contact and other coverage remain
open. No public export, F install or stable promotion; full goal incomplete.
