About ProofMark Studio

ProofMark Studio is a working hub for proofing, converting, signing, and transforming PDFs. It composes independent sibling apps behind a single catalog UI, so every tool keeps its own repo, test suite, and release cadence while the hub stays thin.

What ships today

• A React catalog of 49 tool tiles across Organize, Convert, Edit, Sign, Proof, AI, and Workflow groups.
• Per-tile feature flags (TOOL_<SLUG>_ENABLED=false) that demote a live tile to a paused stub in under a minute — no redeploy required.
• A structured /api/tools contract that the React catalog reads at runtime, so the UI can never drift from the registry.

Philosophy

• Composition over monolith. ProofMark PDF, Text Inspection, and future siblings are independent FastAPI processes; the hub routes and redirects, nothing more.
• Small verifiable steps. Every phase has a failing test first, a promotion commit, and a tag when the exit gate is met.
• Observability over cleverness. Every decision point logs [tag] message so silent failures have nowhere to hide.
