Local repro confirms the SDK build + runtime pipeline serves nested src/web/public/<subdir>/* assets correctly:

• agentuity build copies them into .agentuity/client/tac/{Logo,Icon}.svg
• They show up in agentuity.metadata.json assets list
• They're included in the deploy zip
• Running the production bundle locally (bun .agentuity/app.js), GET /tac/Icon.svg returns 200 with image/svg+xml

So the SDK side looks healthy. The 404 most likely originates in the deploy/serve layer (CDN path mapping or ion proxy). Tracking that on the infra side: agentuity/infra#491.
