Summary

Stacked on !1199 / #711. Keeps Swap /?from=&to= in sync after picker, flip, and amount (replace, not push).
Direct-pair reverse quotes via exactField=output and reverseSimulateSwap. Execute stays offer-in + min received. Multihop / wrap-mapper stay pay-sided.
Swap header Share (buildCanonicalSwapShareUrl) — Web Share on coarse+narrow, copy otherwise. Never window.location.href.
/create?a=&b= prefills listed or checksum custom (C542-11). /trade?from=&to= replaces to the unique factory pair path.

Closes #713.

Test plan

make verify-issue-713
make verify-issue-711 (inbound parse still green)
make verify-issue-542 (Create Pair catalog + prefill)
Swap: change tokens after /?inputCurrency= and confirm the bar rewrites to from/to without a history entry
Direct pair: exactField=output fills You Receive; You Pay is reverse sim; Swap still sends offer-in
Share copies canonical /?from=&to= (no leftover Uniswap keys)
/create?a=&b= prefills listed CW20s and does not auto-submit; hostile/native ignored
/trade?from=&to= navigates to /trade/{pair} when exactly one factory pair matches
Playwright e2e/swap-url-sync-713.spec.ts with a live VITE_FACTORY_ADDRESS (make deploy-local)

## Summary - Stacked on !1199 / #711. Keeps Swap `/?from=&to=` in sync after picker, flip, and amount (`replace`, not push). - Direct-pair reverse quotes via `exactField=output` and `reverseSimulateSwap`. Execute stays offer-in + min received. Multihop / wrap-mapper stay pay-sided. - Swap header Share (`buildCanonicalSwapShareUrl`) — Web Share on coarse+narrow, copy otherwise. Never `window.location.href`. - `/create?a=&b=` prefills listed or checksum custom (C542-11). `/trade?from=&to=` replaces to the unique factory pair path. Closes #713. ## Test plan - [ ] `make verify-issue-713` - [ ] `make verify-issue-711` (inbound parse still green) - [ ] `make verify-issue-542` (Create Pair catalog + prefill) - [ ] Swap: change tokens after `/?inputCurrency=` and confirm the bar rewrites to `from`/`to` without a history entry - [ ] Direct pair: `exactField=output` fills You Receive; You Pay is reverse sim; Swap still sends offer-in - [ ] Share copies canonical `/?from=&to=` (no leftover Uniswap keys) - [ ] `/create?a=&b=` prefills listed CW20s and does not auto-submit; hostile/native ignored - [ ] `/trade?from=&to=` navigates to `/trade/{pair}` when exactly one factory pair matches - [ ] Playwright `e2e/swap-url-sync-713.spec.ts` with a live `VITE_FACTORY_ADDRESS` (`make deploy-local`)
