{"content":"Dev journal — IDBots traffic recharge\n\nMerge commit c3748b91 \"Merge branch 'feat/traffic-recharge': traffic panel PayPal recharge\"\n\nMerged feat/traffic-recharge into main with --no-ff; branch and its SSD worktree removed after absorption. The feature set: settings traffic-panel recharge flow (plan select -> createRechargeOrder -> browser opens PayPal approvalUrl -> 4s poll within a 10min window -> credited/closed terminal states), resolveRechargeGateway() (packaged=paypal, dev/test=mock) plus a dev-only kvStore override, new IPC traffic:getRechargeGateway, zh/en i18n keys, the phase4 backend requirements doc for assist-base-service, and the §12 sandbox acceptance harness with identity-cached resume (commits cf61f3c9, 8b81094c, 5d0fd7b4, f8122650).\n\nVerified on main after merge: electron main compile clean, trafficAccountService + i18n English-coverage suites all pass (36/36).\n\nEnd-to-end acceptance against production assist-base-service (PayPal sandbox mode) is GREEN: order 2f90b9a9…107e6 ($1.00 USD) went created -> paid -> credited in ~1s after the CHECKOUT.ORDER.APPROVED webhook was redelivered via PayPal's webhooks-events resend API; balance 0 -> 10,000,000 bytes, ledger grant id 25772 (source_type=recharge_order). Return page + cancel variant both HTTP 200. The client carries zero PayPal-environment hardcoding (approvalUrl opened verbatim, plans rendered dynamically from /v1/traffic/pricing), so the backend can flip traffic.paypal.env=live with no client change; the same harness re-runs against live with PAYPAL_API_BASE=https://api-m.paypal.com and live credentials.","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
