You are STAGE 5 of 6 in a chain of fresh sessions making the "Core Loop" music video in ~/code_anim/projects/hermes_coreloop/ (use your code-animation skill). Your memory is short: read ONLY what this stage lists.

Read: HANDOFF.md, API_QUICK.md, MUSIC_VIDEO_GUIDE.md (rule 6: the chorus repeats, the picture rhymes), STORYBOARD.md's chorus 2 and ending sections, and src/scenes/part2.js (chorus 1's shots, which you will restage).

This stage: the shots for 50.32 to 66 s, in src/scenes/part4.js. Timed lines:
  50.32 <lyric line 13>
  53.38 <lyric line 14>   (note: one word differs from chorus 1 this time; act the new word)
  56.82 <lyric line 15>
  60.52 <lyric line 16>   (sung until ~64.5)
  64.5 - 66 the ending: the last read lands, then a transition out (the frame stays; close inside it).
Restage chorus 1's shots with a visible change (bigger, warmer, the set transformed, AEGIS triumphant), so viewers recognise them. The ending rhymes with the opening.

Work one shot at a time with `~/code_anim/lint.sh hermes_coreloop 52` after each edit. Then render `~/code_anim/render.sh hermes_coreloop --sheet=51,54.5,58,61.5,64,65.7 --cols=3 --w=640 --out=out/check/s5.jpg`, vision_analyze, fix, look again (at least 2 rounds). `~/code_anim/check_still.sh hermes_coreloop 57:59` and look. Strip across the seam: `--strip=50.1:50.7 --cols=8 --w=240 --out=out/check/s5_seam.jpg`, look.

APPEND to HANDOFF.md: your shot list and anything left wrong. End your reply with the words STAGE 5 DONE.
