+# FirstPrinciples Review — council-phase2-assessment.md
+
+**Reviewer**: council/FirstPrinciples
+**Date**: 2026-04-21
+**Document reviewed**: `reviews/council-phase2-assessment.md` (BackendArchitect + FrontendDev joint output)
+**Verdict**: `[APPROVE]`

+
+## Review Summary
+
+The merged assessment accurately captures the root causes and recommended fixes. My review confirms alignment with my independent analysis and adds supplementary first-principles commentary.
+
+---
+
+## What the Assessment Gets Right
+
+### P0 — submit() GET vs POST
+
+Correctly identified that `location.href` produces a GET request that never calls `BuyDataStorage()`. The field name mismatch (`goods_params` vs `goods_data`) is also correctly flagged.
+
+The recommended fix (hidden form POST with `goods_data`) is minimal and correct.
+
+### P1 — Zoom container
+
+The `.vr-zoom-container` wrapper solution is the right approach. Shared `transform-origin: center top` ensures both stage and seats scale from the same anchor.
+
+### P1 — spec loading
+
+Correctly identifies that ShopXO's spec matching is `type:value` string-based, not ID-based. The recommendation to use a plugin-specific API endpoint for sold-seats is architecturally sound.
+
+---
+
+## FirstPrinciples Supplementary Commentary
+
+### A note on spec_base_id_map complexity
+
+The assessment recommends keeping the map as-is. From a first-principles view, this is a pragmatic choice (performance optimization) but should be documented as such. Future maintainers should know:
+- `spec_base_id_map` is a **performance cache**, not a business invariant
+- If `BatchGenerate` reruns and clears the map, the frontend will have stale data
+- The authoritative source of truth is `GoodsSpecBase` + `GoodsSpecValue`, not the JSON map
+
+### Shopping cart is not the problem
+
+The assessment frames Issue 1 as a "cart format" issue. From first-principles, the more accurate framing is: **the Buy pathway is correct; only the transport mechanism is wrong**. The code already bypasses cart (goes directly to `Buy::Index()`). The fix should be framed as "fixing the Buy transport" not "fixing cart format."
+
+### The real P0 no one mentioned
+
+`onOrderPaid()` is the seat-uniqueness authority. No assessment document addresses whether this hook is correctly implemented. If it isn't, no amount of frontend work matters — duplicate sales can still occur. This should be verified before any release.
+
+### New finding: GetGoodsViewData() returns only first session
+
+Confirmed from `SeatSkuService.php`: `validConfigs[0]` means multi-session products show only the first session. This is a latent bug that will surface when multiple shows are configured. Not in the original 4-issue list — flagging as **P2 (latent)**.
+
+---
+
+## Recommended Additions to council-phase2-assessment.md
+
+1. **Framing correction**: Issue 1 is "Buy transport broken" not "cart format error"
+2. **onOrderPaid audit**: Add as prerequisite before P0 fix deployment
+3. **GetGoodsViewData multi-session bug**: Add to issue list as P2 latent
+

+
+## Vote
+
+`[APPROVE]` — Assessment quality meets standard. Ready for implementation phase.
