Shopping. Photo in → Spotter (colour, garment, pattern, fabric) → Finder searches (≤3, ≤12 candidates) → Checker verifies price/stock in the page, JSON-LD or a confirmed quote → Ranker picks best verified price first. Ask-the-seller shows the exact message before Send. Place order is a confirmation screen (item, seller, price, delivery, name/address from Setup); the seller gets the address only on Confirm. Picker picks cheapest/fastest/arrive-by delivery, Buyer rejects a stale price or seller, Tracker chases confirmed orders every 6 hours and needs eyes after 3 unanswered reminders. Construction. Plan in → Plan Reader extracts rooms (user corrects, per-room accuracy shown) → Quantity Surveyor builds a BOQ in plain code (whole-building per-sqft rates +7.5% wastage, tiles +10%, paint by perimeter) → House Artist (Muse Image, ≤5/hunt, labelled concept-only) → user Approves BOQ + image by hash (any edit clears approval, vendor search/calls refuse without it) → vendor search (≤10 items, 20 searches, 8 vendors/item, city in the query) → Quote Caller → Compare (Best/Cheapest per item, running total, no house total until all quoted). Safety. Untrusted page/seller text never picks recipients or prices — only code acts, from DB values, after a logged-in click. Only opted-in sellers are messaged (STOP flips opt-in off instantly); everyone else gets an invite link from the user's own WhatsApp. Pages refuse to run before robots/captcha/login, fetch politely (10 s, 2 MB, ≤3 redirects), and never save others' images.
