qp-plan

# qp-plan — Prepare (inventory → MECE �� TCs) Input: a target that passed `qp_tools.sh target-class` (PUBLIC or PROFILE_OK) and an adapter line from `adapter-probe`. Optional: a plan/spec document path (`--plan <file>`). Optional profile. ## 1. Surface inventory — observe, do not guess Open the entry route with the adapter (web: navigate + accessibility snapshot; desktop: screenshot). Record every **navigable surface** you can see: links/routes, menu items, buttons that open a dialog, forms, tabs. One row each: ``` | id | kind (route·menu·dialog·form·tab) | label as shown | how reached (from which surface, which action) | observed? (yes/no) | ``` Rules: ⓐ **do not invent routes** — a surface is listed only if you saw its trigger; ⓑ parameterised routes (`/item/:id`) are listed as `ROUTE_PARAMETERIZED`, not filled with a made-up id; ⓒ if the entry route did not load → stop with `HARNESS_ERROR reason=entry-unreachable`. Write `qp/plan/inventory.md` with the header lines `target-class: …` (the tool's literal output), `ADAPTER=… evidence=dom|pixel` (the probe's literal output), `engine=mcp-fallback` (or `engine=capability:<id>` only if the `qp` router found a registered capability — never a browser name; a floor-tier sim wrote `engine=chromium` when this line did not say so, 2026-09-05), `plan_doc: <path|NONE>`. ## 2. MECE check Walk the inventory once more against the snapshot: any visible navigable element not in the list → add it (**missing**); any two rows reaching the sa...
