Architecture

Network Tools is a static React/Vite application wrapped in the shared Toolbox shell. Workbench.tsx owns only transient view state and delegates to small pure modules:

• network/url.ts resolves and decomposes URLs with the platform URL parser and returns a password-redacted display value.
• network/dns.ts constructs one bounded zone-file record; IPv4 and IPv6 parsing comes from @add-ideas/toolbox-helpers.
• network/http.ts parses a pasted header block and constructs an explicit CSP from source tokens.
• network/mime.ts is a project-authored offline reference table.

All version 0.1 operations are short, bounded and synchronous, so the app does not create a worker. There is no server API, service worker, persistence layer or runtime lookup. Relative entry and asset URLs keep the production build relocatable below a nested portal path.
