No visual change until stage 9 unless stated. |---|---|---| | 0 | GUI capture goldens: a handful of scenes rendered hidden in capture mode, PPM hashes checked in (same machine/driver) | the safety net the GUI stages need; machine- and driver-specific, so a LOCAL gate only, never CI | | 1 | pure moves: render → `src/draw.zig`; Presentation/animation out of layout.zig | no behaviour | -| 2a | clock plumbing: `now_ns` into pump/events, `nextWake`, `advance`, deadlines for linger/hover; all shells pass now and sleep to the wake; six tick drivers deleted; ack moves into pump; capturePrevious only when transitions are on. Animations still compute `frame = floor(elapsed / 16 ms)`, so every curve is identical | pacing is corrected (144 Hz no longer ~25% slow, ssh no longer drifts): a bug fix allowed in this phase. Unit tests step an injected clock by exactly 16 ms, so their numbers do not change. The snapshot harness runs the binary with `--test-clock` (each core-time step is exactly 16.67 ms per tick request, as today), so goldens see the same sequence and `stable` (test/snapshot.zig ~861) is unaffected by wall-time pacing | +| 2a | clock plumbing: `Host.now` (the shell's monotonic ns) and `Pardes.advance(now)`, which runs one `.tick` per whole 16 ms frame since core time last stood still; `nextWake()` lists every core animation and answers the next frame while anything moves, the wait's end while something only waits (message linger, look-hover delay), null when idle; the pump sleeps to it and draws only stepped frames. No shell posts `.tick` any more (tty's timer thread only wakes the wait; GUI's AnimationClock, web's JS tick bank and the detached server's and the board's ticks are gone; grid mode moves its virtual clock straight to the next wake). `acknowledgePanelPresentation` stays in the shells (revisit at stage 8: grid mode acks `&.{}` on purpose). capturePrevious only when transitions are on. `.tick` stays as the one-frame step `advance` and the unit tests use, so every curve and every asserted number is unchanged | pacing is corrected (144 Hz no longer ~25% slow, ssh no longer drifts): a bug fix allowed in this phase. PARDES_TEST_CLOCK (set by the snapshot harness): tty and the detached server answer a virtual clock that a timed-out wait moves exactly to the core's next wake, so goldens replay the same frame sequence on any machine load. Review fixes: tty's wake timer is interruptible (a newer, shorter request cuts short an older sleep); a wait (linger, hover delay) is jumped to its end in one step, never counted against the 240-frame catch-up cap; an overshoot under 1.5 ms after a step is let go, so 60 and 120 Hz take exactly one step per display frame. Known exceptions: the GUI still polls every 16 ms when idle (SDL events, gamepad, fs tick, smooth scroll depend on it; revisit at stage 8); a minimized GUI renders every stepped frame of a running animation (stage 8) | | 2b | (on `fx`, feel-reviewed) Tween/Spring curves, settle rules, OKLab crossfades, new durations from §8.1 | a look change, kept apart from 2a so either can be bisected | | 3 | paint functions take `s: *Surface`; delete the swap hack | mechanical, wide | | 4 | PLACE: Region list built once; renderPane/tags/notices read their rects from it | wait for tag→Text; the refactor is already replacing BOX_H with `pane.tag_rows` and `p.tagTop/bodyTop(pane, r)` — PLACE absorbs those into the region rects | |
