    "headline": "Browser-local construction takeoff that records how every measurement was made — by a person, by one click, or by an agent — which is the right provenance model for a document that ends up in a bid.",
    "body": "OpenTakeoff is an Apache-2.0 quantity-takeoff tool that runs entirely in the browser: drag in a PDF, an image or a whole zip plan set, set or auto-detect the scale, and trace areas, cut-outs and markups against named conditions. Two decisions stand out on the captured surface. First, 'nothing leaves your browser' — for contractors, plan sets are commercially sensitive and often under NDA, so a local-only tool removes a real adoption blocker rather than a theoretical one. Second, and more interesting for an agent register: the app states that every measurement keeps its scale and how it was made — a person, one click, or an agent — over one shared engine. That is provenance at the measurement level, and it is exactly what a takeoff needs, because a quantity that feeds a bid has to be auditable regardless of who or what produced it. Most tools bolting on AI assistance treat human and machine output as interchangeable; recording the difference is the more honest design. The surface is the running application rather than a marketing page, so what Hlido could verify is the UI itself: conditions, waste percentages, fill styles, scale setting, voice command, zone and snap aids, and a sample medical-centre floor-finish plan for first use. What is not visible anywhere is the agent interface it advertises — no MCP endpoint, API documentation or integration guide was reachable — along with no accuracy evidence, no version and no adoption. The agent claim is therefore stated but unverified.",
