Overlay doctrine for captions in HyperFrames videos — the caption MODEL (drop / rail / embed) and the rule that captions are an OVERLAY composited on top of the film, never a reserved bottom band you shift content up to avoid. Load when adding captions/subtitles to a talking-head or launch video, when deciding whether a phrase should be dropped, ride the verbatim rail, or be promoted to a scarce embedded climax, when laying out a composition that will carry captions…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Captions Overlay Doctrine > **Overlay doctrine — supplements the upstream `/hyperframes` skill's `references/captions.md`. Applies ON TOP of it; do not expect it folded into the upstream skill.** Two ideas combine here. First, the **caption model** — every spoken phrase is `drop`, `rail`, or `embed`, and embed is the scarce earned peak, not the default. Second, the **overlay law** — a caption line is composited ON TOP of the film as an overlay; it is NOT a reserved zone, so you never shift content up or leave a dead band to "make room" for it. The two reinforce each other: because captions ride as an overlay (the verbatim rail in front, the occasional embed behind the subject), the composition keeps its full frame and centers on the true vertical center. ## The caption model — drop / rail / embed Every spoken phrase is one of three things: | | What | How it's shown | …

How to install
mdr add heygen-com/hyperframes/captions-overlay@sha256:95edff863c75088bThe line at the top of this page pins the label git:20261021.6882293, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
