Phase as the $[\hat X,\hat K]$ commutator

These are sparse samples decoded from the current MP4, not newly rendered illustrations. They can support checks of the sampled states and labels, but cannot establish continuous motion, timing, transitions, or the absence of problems between samples. Use the full MP4 when judging those properties.

Caption
Phase as the $[\hat X,\hat K]$ commutator
Image description
A complex spiral follows an x–k loop and returns to its original magnitude envelope with a quarter-turn of phase remaining
Before the animation
Chapter lines 986–990
Chapter lines 992–996
After the animation
Chapter lines 1004–1004
The infinitesimal closed $x$-$k$ loop is generated by $[\hat X,\hat K]$. Because the finite loop leaves a phase translation, and phase translations are generated by $iI$, we have:
Chapter lines 1006–1010
Generation source
Main script --render draws the ordered +k,+x,-k,-x loop and uses the imported packet-phase script for shared artwork, math, and encoding libraries. --check and --encoded-check produce companion checks; there is no input movie.
Mapping evidence and limits
Exact NAME match. Matching validation records the -pi/2 residual phase, 480 frames, 30 fps, 1440 x 900, 16 s, and final hold after 13 s. Matching encoded-validation.json confirms the frame count and renderer comparisons.
Source SHA-256 values identify the exact downloadable bytes in this packet. The source mapping and recorded checks explain the likely generation pipeline; they do not prove that these exact source bytes produced the movie. A GitHub link pinned to a commit is provided only when the delivered source bytes exactly match that path at the build's Git HEAD.

Existing generator checks (2 reports)
These are existing author-produced generator reports, copied without changes. Their checks were not rerun for this packet and are not independent certification. A report may describe an earlier generation run; inspect its contents before applying its claims to the current movie.

Decoded contact sheet
Extraction method: Twelve evenly spaced decoded frame indices, including first and last. Native-resolution JPEGs from the encoded MP4; timestamps read from FFmpeg showinfo. No source rerendering. Frame indices are zero-based. Sparse samples do not establish continuous motion or capture every transition.. Frame indices are zero-based.
