  "name": "Room Reference Planner",
  "status": "Free, ad-free availability beta; public discovery and human outcomes unmeasured; no MCP integration",
  "purpose": "Prepare identified rectangular furniture in two alternatives, correct finished interior measurements, inspect references and conservative gap intervals, then save/reopen one editable project.",
  "interface": "Ordinary HTML labelled controls; no callable remote service",
  "inputs": "Millimetres; finished-interior room faces, south door/north window, wall-anchored obstacle, furniture dimensions/uncertainties, wall or same-arrangement item-edge references and signed offsets, two intents/memberships, household gap preference and notes.",
  "outputs": "North-up footprint plans, nominal geometry warnings, horizontal gap and conservative contributing-input interval, change history, explicit local JSON project save/open and derived SVG download.",
  "rules": "Axis-aligned rectangles only; shared uncertain parameters cancel algebraically. Item-edge references must exist and be placed in that arrangement. Cycles, unknown/wrong-axis references, nonfinite dimensions and unsupported JSON are rejected. Preference is not a standard. No physical fit, delivery, heat/service, accessibility or purchase approval.",
  "price": "Free; no ads, accounts, paid API or runtime service",
  "data": "Room inputs stay in tab memory until explicit local JSON/SVG download. Native selected local JSON only, 256 KiB limit. No automatic persistence, room-data upload, analytics, ads, credentials or external assets. A hosting provider receives page/asset requests and associated network metadata. Closing/reloading loses unsaved work.",
  "return_workflow": "Save a JSON project, deliberately open the selected file, change inputs through labelled controls, Apply, inspect both alternatives and save. New/Example/valid Open request an explicit replacement decision when current work exists; Keep preserves current project and drafts. A download request is not confirmation that a copy reached disk.",
  "test_limits": "Selected synthetic Firefox desktop and390 CSS iframe tasks, sixteen preservation/file-return checks, native saved JSON return, exact UTF8 boundaries and qualified SVG output are recorded. One optional WebDriver U+E007 activation is unresolved. Physical phone/OS-picker/spoken-reader/full-keyboard usability, accessibility conformance, security certification, MCP compatibility, human benefit and measured public discovery are unverified."
