- Remove legacy_tasks.py, hybrid_state.py, render.py - Remove old task modules (analyze, execute, execute_sexp, orchestrate) - Add streaming interpreter from test repo - Add sexp_effects with primitives and video effects - Add streaming Celery task with CID-based asset resolution - Support both CID and friendly name references for assets - Add .dockerignore to prevent local clones from conflicting Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

;; stream-process-pair template (streaming-compatible)

|
;; Macro for processing a video source pair with full effects.
|
|
;; Reads source, applies A/B effects (rotate, zoom, invert, hue), blends,
|
|
;; and applies pair-level rotation.
|
|
;;
|
|
;; Required context (must be defined in calling scope):
|
|
;; - sources: array of video sources
|
|
;; - pair-configs: array of {:dir :rot-a :rot-b :zoom-a :zoom-b} configs
|
|
;; - pair-states: array from (bind pairs :states)
|
|
;; - now: current time (t)
|
|
;; - e: audio energy (0-1)
|
|
;;
|
|
;; Required effects (must be loaded):
|
|
;; - rotate, zoom, invert, hue_shift, blend
|
|
;;
|

;; Usage:
|
|
;; (include :path "../templates/stream-process-pair.sexp")
|
|
;; ...in frame pipeline...
