Caravan workflow coverage

Every offered strategic choice remains a separate Jev decision. Recognizing an arrival does not deliver cargo, add shields, infer revenue, or establish a route.

caravan.py covers three original GAME resources:

Stage	Required native choices
CARAVANBUILT	Every offered commodity, including Food, plus the actual Supply And Demand button
CARACONFIRM	Confirmed, Reconsider, and the actual Confirm and Zoom button
CARAVANMENU	Keep moving and every actually offered trade-route or wonder option

The commodity catalog must match the original sixteen RULES @CARAVAN entries; Food and the arrival labels are independently bound to original LABELS entries. The completion prompt must name an original land trade unit (role7). The prompt, all foreground text, each visible option and every required button must agree with the source. No commodity or available destination is filled in from state.

A PNG hash check precedes native-frame and radio checks. The complete black frame, its original light/dark bevel, and the full option band are inspected. Every detected original radio must match one observed option in the same column and at the original row spacing. An OCR-missed option whose radio remains visible therefore rejects the dialog. Any extra foreground row, missing control, damaged frame, unknown commodity or changed source also rejects it. The model selects a radio followed by normal Enter, or an actual button click without extra Enter.

These caravan layouts currently have original-source and synthetic frame tests. The shared frame/radio primitives also pass a retained original Foreign Minister capture; that is not live caravan calibration. No caravan encounter was available in the retained debug campaigns, and no campaign inputs were issued for this implementation. A differing real layout remains unsupported until it is observed and reviewed.

The resulting CARAVAN, FOODCARAVAN, CARAVANOTHER and CARAVANHOME notices require complete exact original bodies and a sole observed OK. Acknowledgement records the visible statement; subsequent native observations establish state.

Production of an offered Caravan/Freight already uses the existing production chooser. Ordinary movement already permits an original role7 unit to request entry into an occupied, known foreign city. Transport boarding/landfall remains separate native input and decision handling. The original manual describes city entry, naval carriage, trade and wonder contribution (local transcription lines6973–7014); GAME resources2943–2984 supply the dialogs.

The planner separately offers trade_delivery and assist_wonder objectives to living original Caravan/Freight units. Delivery uses owned or remembered city coordinates on explored land, excluding the current square and the uniquely observed home city. Wonder assistance uses an owned city's exact current wonder production and the public not_built status. Original unit rules and observed HP are corroborated. Unknown cargo demand, prospective revenue and foreign ownership are never supplied as facts.

The existing category/target selection retains each offered leaf and its full label. The candidate budget still reserves Hold and uses the same documented round-robin ordering and omission counts. Objectives do not prune or execute movement commands. Reaching the target completes only the travel objective; the original arrival choice remains a separate model decision. Changed wonder production, lost city/home identity or removed unit slots invalidate the plan without claiming delivery or shield contribution. Offline verification binds each new target to the native records and the actual model request.

Trade entry into an occupied remembered city no longer requires a foreign-owner field: the native observation deliberately withholds that field. It requires a unique remembered city coordinate on observed land and excludes an owned city. The move label explicitly states that the present owner is unverified. An enemy unit on a bare square does not enable a civilian trade interaction.

The Supply And Demand inquiry/report (SUPPLYSEARCH/SUPPLYSHOW) still lacks live layout support and will pause if encountered. No home-city change is introduced; the original game rejects changing a trade unit's home city.
