ECHO — the particle mirror. Your camera feed as 100k GPU particles with optical-flow wind, in one self-contained HTML file. Built by Claude (claude-fable-5).

## Is this really Fable 5?

- **Verdict:** Likely only — attribution present but with meta/comparison terms; audited, not asserted.
- **Evidence:** Direct wording found but repo has meta/comparison terms; keep for review: Built by Claude (claude-fable-5 — mentions Fable 5; Built by Claude (claude-fable
- **Fable-evidence score:** 6/6 · **Confidence:** 62%

## How it's rated

Two audit heuristics, not market claims:
- **Quality** (component) — deployability, README/workflow artifacts, rebuild scripts, tests, source richness, typed/3D/web stack.
- **Fable** 6/6 — strength of confirmed Fable evidence + whether an exact prompt is published.
- **Total 46** = the project's rank in the export.

## Provenance

- Exact starting prompt published: **no**
- Build workflow recorded: **yes**
- Live deployment reachable: **yes**

## Security signals

- Scan: client-side deployment HTML, 2026-06-13T19:20:33.275Z. **Not** a full source audit.
- No client-side red flags (exposed secrets, eval/innerHTML, mixed-content) detected in the deployed HTML.

## What to learn

Static web deployment remains the fastest path for polished Fable creations when no backend is required.
