# Advanced Show patterns

## GSAP, smooth scroll, and staged interactions

Keep the actual timeline, trigger ranges, easing, scroll owner, RAF,
pointer state, and cleanup logic live. In the editor iframe, deliver
real wheel/touch input to the inner scroller and inspect its
`scrollTop/scrollHeight`, active index, transforms, and animation
progress. A static first screen or synthetic `.click()` is not proof.
Pin shared libraries and guard initialization if optional dependencies
fail.

## Topology, WebGL, WebGPU, canvas, and 3D

Upload models, textures, HDR/EXR, buffers, shaders, workers, wasm,
decoders, and data files with explicit roles. Preserve URL identity
when loaders cache resources. Validate binary headers, MIME, decode,
canvas bounds, nonblank pixels/render targets, time-separated motion,
pointer/scroll response, resize, reduced-power fallback, and context
failure. Avoid assuming a backbuffer read proves the visible result.

## Webcam and gesture input

- Camera use must be visible, purposeful, and initiated by an
  understandable user action.
- Ask browser permission normally; never bypass or trick consent.
- Provide denied, unavailable, loading, and no-camera fallbacks.
- Show an active-camera indicator and a reliable stop/release path.
- Process locally by default. Do not upload frames, biometric
  features, or background recordings unless the user explicitly
  requests a legitimate feature and the current privacy policy,
  consent, retention, and BaaS rules allow it.
- Do not fingerprint, identify people, infer sensitive traits, or
  keep the camera active after the experience stops.
- Test HTTPS, mobile orientation, mirrored coordinates, performance,
  keyboard/touch fallback, and blank/edit/embed permission behavior.

## GitHub or local repository import

Work only with a repository the user owns or is authorized to use.
Preserve its license and third-party notices where required. Inspect
source, routes, assets, environment variables, server assumptions,
and tests. Never expose a GitHub token, deploy key, `.env`, private
submodule, issue data, CI secret, or commit metadata that the user did
not ask to publish.

Map the client application into meaningful live Pieces. Upload
source-specific runtime assets; use pinned shared dependencies; map
persistent/server behavior to explicit BaaS resources or approved
services. Do not upload a repository archive or opaque `dist` page
and load it through an iframe. Validate the ZZD runtime independently
from the local development server.

## Public visual references

Separate internal engineering from public distribution. For assigned
Hightopo Extended work, fetch the complete current protocol at
`/collaboration/protocol/hightopo/`, its hash manifest at
`/collaboration/protocol/hightopo.json`, and the current task detail.
Keep the existing worker, claim and Show when refreshing. The current
protocol supersedes stale generic permission-stop instructions, not
the exact source scenario or factual source-access limitations.

Reuse recorded user authorization within its actual scope. Do not ask
the same development/upload permission every phase. Record unresolved
public-distribution questions once as `publish_review_pending`; this
is not a blanket stop for authorized local study/internal development.
Public distribution needs suitable rights and scoped user authority;
existing explicit authority need not be requested again. A private
Show flag alone does not prove all historical asset paths are private.

Preserve faithful geometry, textures, animation and interactions.
Apply source-owned Chinese localization and neutral identity/resource
sanitization without hiding panels or replacing the scene with a
low-quality approximation. Use authorized non-trial engine/config
where available; distinguish removable demo branding from required
legal notices. Do not bypass authentication, activation or DRM, erase
required legal notices, leave trackers or private identity, or claim
that renaming/private mode establishes rights. Report real platform
scope, upload-type or preview-access errors once as technical issues,
not as a repeated copyright confirmation. Continue independent work.
