# Verification

Use the lowest verification level that proves the requested result:

| Level | Required evidence |
|---|---|
| L0 | Static checks such as the focused verification script, `npx tsc --noEmit`, tests, and build. |
| L1 | A real Agent run against the editor at `localhost:5199`, followed by structural and rendered evidence. |
| L2 | The packaged desktop app completing the user scenario, including human visual review where automation is insufficient. |

Runtime behavior changes require L0 + L1. Release and desktop-only changes also
require L2 when the packaged app is the behavior under test.

Prefer two signals:

1. `read_project` for structure: assets, tracks, items, frame placement, timeline duration.
2. A visual capture path for rendered evidence at exact frames.

Use `view_timeline_frames` for composed timeline proof. This verifies the edited OpenChatCut timeline: trims, layers, captions, effects,
markers, placeholders, crops, transitions, and layout.

For raw source-asset frame inspection, choose the cheapest path based on where
the bytes live:

- The agent in this build has no local filesystem access; all source bytes live
  in the project media store (`/media/uploads/`). Use `view_asset_frames` with
  the project asset id, the server takes an ffmpeg contact-sheet fast path
  automatically, so it is already the cheapest source-frame route.
- `view_timeline_frames` renders the composed timeline (the editor-truth check);
  `view_asset_frames` samples raw source frames. Pick by what you are verifying.
- There is no separate `get_contact_sheet` tool in this build, the contact
  sheet is what `view_asset_frames` / `view_timeline_frames` already return.

Use local/remote source-frame artifacts only for source understanding, moment
selection, and rough trim decisions, not as edited output or timeline proof.
