Multi-Model Vision Verification Factory (atomic-media-generator)

Code: 02_ai-engineering-code/atomic-media-generator/scripts/run-vision-bridge.mjs + README.md

Problem. Generate learning media (infographics, step-flows, tables, formulas) at scale and verify each asset actually matches its spec.

What I built. A spec-driven asset factory with a two-model verification bridge:

Stage 1 — primary generation: ChatGPT via Playwright browser automation (zero marginal cost).
Stage 2 — secondary validation: Gemini API vision extraction with structured schema output.
Stage 3 — consensus: reconcile both with 85px Euclidean drift, fail-closed — disagreement halts the asset.
Stage 4 — finalize: schema-validated SVG/asset wrapper.

Hard invariants (from the repo). No legacy coordinate fallback · no heuristic pixel guessing · missing gate evidence = failure · spec-derived prompts are canonical · no idle waiting during API cooldown if other work is queued. 43 imported assets validate against a JSON schema (Zod/Ajv); Vitest-backed.

Why it matters. Multi-model consensus + fail-closed gating is exactly the "make the model trustworthy" problem applied-AI engineers get hired to solve. Also shows creative cost engineering (free primary, paid verify).
