# Auction Socket-Only Bidding Report

**Branch:** `auction-lifecycle-delivery`
**Date:** 2026-07-30
**Classification: READY AFTER MANUAL QA**

---

## 1. Classification

READY AFTER MANUAL QA — public bidding is Socket.IO-only in code; live staging Socket lifecycle not executed.

## 2. `/place-bid` status

**Removed** from the public Auction contract.

| Artifact | Action |
|---|---|
| `BidRoute` POST `/place-bid` | Removed |
| `bidController.placeBid` | Removed |
| `Bid.placeBid` HTTP helper | Removed |
| OpenAPI `/place-bid` | Removed |
| Postman | Regenerated without `/place-bid` |
| `placeBidAtomic` | **Kept** (canonical internal service) |

**Client dependency search:** no in-repo mobile/web app called HTTP `/place-bid`. Admin dashboard already used Socket `auction:enter` + `auction:bid-updated`. No temporary deprecated HTTP compatibility route retained.

## 3. Socket event inventory

| Event | Direction | Authentication | Service | Ack | Broadcast | Tested |
|---|---|---|---|---|---|---|
| `auction:enter` | C→S | handshake | Auction load + join | `{success,data:snapshot}` | `auction:entered` to joiner | unit |
| `auction:leave` | C→S | handshake | room leave | `{success,data}` | none | unit wiring |
| `auction:bid` | C→S | handshake client | `placeBidAtomic` | success/replay/fail | after new Bid only | unit + Mongo |
| `auction:bid-updated` | S→C | room | — | — | canonical | unit |
| `auction:extended` | S→C | room | — | — | when extended | unit |
| `auction.bidAccepted` / `auction.priceUpdated` / `auction.extended` | S→C | room | — | — | legacy aliases | unit |
| `auction:ended` | S→C (cron) | room | after `finalizeAuction` | — | post-commit | source test |
| `auction:ended` / `auction:sync-ended` | C→S | handshake | observe only | snapshot if finalized | none | unit |
| live overlay | C↔S | handshake | liveHelper | — | live:* | documented optional |

## 5. Client migration

| Old HTTP usage | Migrated client | Socket event | Status |
|---|---|---|---|
| `POST /place-bid` | none found in-repo | `auction:bid` | N/A — no caller |
| Admin live price UI | `auction-operations.js` | listens `auction:bid-updated`, `auction:extended`, `auction:ended` | Updated |

External mobile apps (outside this repo) must migrate to Socket per `docs/AUCTION_SOCKET_EVENTS.md`.

## 6. Idempotency

Unchanged core rules + Socket-required key; replay/conflict as before.

## 7. Acknowledgement

`{ success: true, data }` / `{ success: false, error: { code, message, ... } }` aligned with `auction:error`.

## 8. Broadcasts

Canonical `auction:bid-updated` + `auction:extended`; legacy aliases retained; no emit on replay.

## 9. Finalization

Client cannot finalize. Cron → `finalizeAuction` → persist → `auction:ended` (skipped on `alreadyFinalized`). Observe-only client events remain.

## 10. Legacy Haraj

Overlay only; no independent bidding/settlement.

## 11. Agora

Optional / partial; not a merge blocker.

## 12–13. Tests

| Suite | Result |
|---|---|
| `auctionSocketContract.test.js` | **812 pass / 0 fail** (812 tests)
| Mongo concurrency | **4 / 4** |
| Full `npm test` | **812 pass / 0 fail** (812 tests)

## 14. Documentation

- `docs/AUCTION_SOCKET_EVENTS.md`
- `docs/AUCTION_MANUAL_QA.md` updated
- OpenAPI/Postman: `/place-bid` removed

## 15. Remaining staging checks

Socket enter → bid → idempotent replay → stale → extension → reconnect → cron `auction:ended` → wallet/Order; confirm no HTTP place-bid callers in deployed mobile builds.

## 16. Merge recommendation

Keep **READY AFTER MANUAL QA**. Do not merge as READY TO MERGE until authenticated staging Socket lifecycle passes.
