Summary

P1 submit() 重构与 BackendArchitect 的 P0-B BatchGenerate() 接口对齐。

Interface Contract Check

Backend P0-B returns:

// SeatSkuService::BatchGenerate() returns:
'data' => [
    'total'            => count($seats),
    'generated'        => $generatedCount,
    'batch'            => $totalBatches,
    'spec_base_id_map' => ['A_1' => 2001, 'A_2' => 2002, ...]  // seatId => int
]

Frontend P1 uses:

// ticket_detail.html:417
var specBaseId = self.specBaseIdMap[seat.seatKey] || self.sessionSpecId;

Key format alignment:

Backend generates: seatId = rowLabel . '_' . colNum → "A_1", "B_10" etc.
Backend parses back via: preg_match('/^([A-Za-z]+)(\d+)排(\d)座$/') → extracts rowLabel and colNum
Frontend sets: seatKey = rowLabel + '_' + colNum (line: rowLabel + '_' + colNum)
✅ Format matches

Frontend accesses specBaseIdMap as flat integer:

// ticket_detail.html:417
var specBaseId = self.specBaseIdMap[seat.seatKey] || self.sessionSpecId;

✅ Fixed from (obj||{}).spec_base_id → flat integer (commit 96337bc84)

goods_params Structure Check

{
    goods_id: self.goodsId,
    spec_base_id: parseInt(specBaseId) || 0,  // ✅ seat-level SKU
    stock: 1,                                   // ✅ 1 per seat (ShopXO-native)
    extension_data: JSON.stringify({
        attendee: seatAttendee,
        seat: { seatKey, label, price, rowLabel, colNum, row, col }
    })
}

✅ stock: 1 — correct for seat-level inventory
✅ extension_data carries full seat context for onOrderPaid() validation
✅ Each seat gets its own goods_params entry → each becomes one order_goods row in ShopXO

Fallback Strategy

var specBaseId = self.specBaseIdMap[seat.seatKey] || self.sessionSpecId;

✅ Graceful degradation: if SKU not generated yet (Plan B transition), uses zone-level SKU
✅ Prevents checkout breakage during rollout

Seat Label Format

Frontend generates labels via: `${seat.rowLabel}排${seat.colNum}座` (e.g., "A排1座") Backend regex: /^([A-Za-z]+)(\d+)排(\d)座$/

Row: 1+ letters (A, AA, etc.) — captured by (\d+)
Col: single digit 1-9 — captured by (\d)
✅ Column numbers > 9 won't appear in {rowLabel}排{colNum}座 format
✅ Regex correctly handles standard seat labels

seat.price Source

Frontend sets seat.price during seat selection (likely from seatMap data). Backend BatchGenerate uses same price source: seatInfo['price'] → sectionPrices[zone] fallback.

✅ Price sources align between frontend (UI) and backend (SKU generation)

Findings

Minor: seat_key format note

The specBaseIdMap key format row_col (e.g., A_1) is consistent throughout. No issues.

Pending Verification (Container)

The following need live testing in ShopXO container:

initGoodsSpecs(112) → confirms is_exist_many_spec=1 + 4 spec_types
BatchGenerate(112, $templateId) → confirms seat-level SKUs in DB
Full checkout flow: seat selection → submit → BuyGoods → order creation

Verdict

[APPROVE] — P1 implementation correctly aligns with P0-B interface contract. The seat-level goods_params approach is sound and leverages ShopXO's native multi-row goods_params support. One minor note: ensure seatMap.sections (price source) is populated in the frontend seat data so BatchGenerate has price information.

Action Required: FrontendDev should sync worktree with latest main (a0690fdd5) to pick up bug fixes.
