Crisis BFT consensus protocol — Go PoC, Python recorder, and CrisisViz: a native macOS scrubbable curriculum visualizer (10 chapters, ~18 minutes at 1×, signed-speed slider with reverse playback).

Replaces the parallel-beats GossipScript with a strictly serial Ch01
timeline (~75 micro-beats over ~5.5 minutes at 1×). Pedagogical
principle: the learner's eye can only follow serial events, so even
though Crisis is parallel by design we serialize for teaching.
Every micro-event is its own beat with its own narration sentence:
think → select payload → select parents → grind PoW → seal → choose
recipient → fly (one at a time) → arrive → open → read body → read
parents → resolve each parent against the receiver's own local view →
verify hash → accept into view. The asymmetry beat (Carl writes γ
before β reaches him) is the centerpiece of the chapter.
Architecture:
- `Ch01Timeline.state(at: t)` is a pure function — replaying every
beat up to t produces the world state. This makes the chapter
scrub-able and reverse-play-able cleanly later.
- The 7 existing scenes become navigation labels — windows of the
same continuous timeline. Arrow keys still let you jump between
them. Scene durations are now per-scene overrides matching each
scene's window in the timeline.
- `Ch02_Graph.swift` rewritten end-to-end (1506 → ~470 lines): one
timeline-driven render path, no per-scene switch, no dense graph
rendering for scenes 4-6 (their content folds into the main
timeline as resolveParent / verifyHash / acceptIntoView beats).
- `ImmersiveView`'s narration overlay now wraps in its own
TimelineView so the displayed text updates at frame rate to
match the active beat. Ch01 reads from
`Ch01Scenes.narrationAt(scene, localTime)`; other chapters fall
back to the static per-scene SceneNarrations.
- `GossipScript.swift` deleted. Old helpers in Ch02_Graph
(renderStagedBeat, renderHashOneWayVignette,
renderLocalDAGDeterminismVignette, renderAncestorConeWalk,
drawCastBubble + view-bubble + composing box) are gone.
- SceneEngine + SceneVideoCapture duration overrides updated for
the 7 new scene windows.
Cast members fade onto the stage only when the timeline introduces
them — Ben isn't on screen during "Aaron writes α", Carl isn't on
screen until "Aaron decides to send α to Carl". No ghosted lanes.
Build clean, harness still 55/55 invariants, 0 audit errors,
281 PNGs, 36/36 MP4 written.
