# PROGRESS — Reference Parity Project

> Read this file FIRST at the start of every session and after every `/compact`.
> Rules live in `CLAUDE.md` (workspace root). Method lives in the `reference-parity-audit` skill.

## Current state

| Field | Value |
|---|---|
| **Phase** | Phase 0 ✅ passed → **Phase 1 starting** |
| **Branch** | `parity/phase-0` (next: `parity/phase-1-admin`) |
| **Status** | Gate passed. Decisions D0–D12 recorded in `DECISIONS.md`. Urgent traces (percent, @Public, login leak) done and delivered. |
| **Next step** | Show the user the `percent` trace + `@Public` list (done), get approval on (a) protecting the 5 ledger routes and (b) the `percent` schema change → then build `01-ADMIN-MATRIX.md` **field-by-field** (D12) |
| **Blocked on** | user approval for: the 5 `@Public` ledger routes (D7), the `percent` column (D9), the D0 migration file (approval required before running) |
| **Last updated** | 2026-09-21 |

## ⚠️ Read `DECISIONS.md` before doing anything

All user rulings live there (D0–D12). Highlights that change how work is done:

- **D12 — the matrix is FIELD-BY-FIELD, not page-by-page**, and a 4-step
  round-trip test per entity is mandatory. Both rules were added to the
  `reference-parity-audit` skill (Step C rule C0, Step E rule E0).
- **D0** — split `fullName` into `firstName`/`lastName` via an additive migration;
  **show the migration and get approval before running it**.
- **D4** — never port broken behaviour, but match calculations/rounding/messages
  exactly; annotate each non-replication «عمداً تکرار نشد — ISSUE #n».
- **D2** — target-only features get status ➕ and are left alone.

## Phase checklist

- [x] P0.1 — All 3 reference folders readable (`henza_server`, `henza_admin`, `henza_pwa`)
- [x] P0.2 — Branch `parity/phase-0` + `docs/parity/` created
- [x] P0.3 — Inventory all 7 projects → `_inv-*.md` (8111 lines total) → consolidated in `00-INVENTORY.md`
- [x] P0.4 — Mapping tables, missing list, extra list (`00-INVENTORY.md` §2–4)
- [x] P0.5 — Draft `PROTECTED.md`
- [x] **P0.6 — GATE passed** — `PROTECTED.md` confirmed, D0–D12 recorded
- [x] P0.7 — Urgent traces delivered: `percent`, `@Public` list, login leak
- [x] P0.8 — Skill updated with rules C0 (field-by-field) and E0 (round-trip test)
- [ ] **P1.0 — user approves: 5 ledger routes, `percent` column, D0 migration** ← HERE
- [ ] Phase 1 — Admin parity (branch `parity/phase-1-admin`, `01-ADMIN-MATRIX.md`)
- [ ] **GATE:** "Admin parity is complete and tested. Shall we move on to the apps (user-app & user-app-v2)?"
- [ ] Phase 2 — Apps parity (`02-APPS-MATRIX.md`, both user apps)
- [ ] Phase 3 — Work through `ISSUES.md` (only when user asks)

## Answered — see `DECISIONS.md` for the full text

| # | Ruling |
|---|---|
| D0 | Split `fullName` → `firstName`/`lastName`, additive migration, backfill, sync, report multi-token rows. Approval needed before running. |
| D1 | Target's stricter auth stands. Build the "reference operation ↔ rid" matrix; explain 172 vs 174. |
| D2 | Audit only what the reference has. Target-only features → ➕, untouched. |
| D3 | Build the 5 missing screens in Phase 2, both apps, plus analytics, `isLoaded`/`sts_verify_step_two` guards, guest toast+home, and v2's cart ceiling. |
| D4 | Don't port breakage; do match calculations/rounding/messages. Unit-test the price formula. |
| D5 | Leave the stray folder; delete last, own commit. |
| D6 | **OTP must verify** — parity gap, fix it (plus expiry + attempt limits, which exceed the reference). |
| D7 | `@Public` ledger routes: list delivered, awaiting approval to protect. |
| D8 | Login leak: **target**, full customer book incl. national IDs and debts. |
| D9 | `percent`: trace delivered — **the target's implementation is wrong**. |
| D10 | Sales expert: keep `AdminUser`; investigate the 5 missing fields; propose `SalesExpertProfile`. |
| D11 | `singleCustomer.vue` → diff-send. |
| D12 | **Field-by-field matrix + mandatory round-trip test.** Added to the skill. |

## Open — awaiting user approval

1. **Protect the 5 `@Public` ledger-write routes** (`DECISIONS.md` group A).
2. **`percent` schema change** — add `makingChargeOffsetPercent` to `Customer`.
3. **D0 migration file** — must be shown and approved before it runs.

## Key context (survives context loss)

- **Domain correction:** the reference is a **gold-jewellery B2B/B2C e-commerce**
  system, not a gold bank. No buy/sell order book, no spread, no deposit/withdraw,
  no P2P transfer, no KYC levels, no daily limits (only `gram_level`), no payment
  callback route, no cron, no websockets. See `00-INVENTORY.md` §0.
- **The gold price formula** (Phase 1 row #1) —
  `henza_server/app/Models/ProductVariant.php:183-190`: `+extra%` → `+7%` margin →
  `+9%` VAT **on the non-metal portion only** → `×grams` → `floor(/1000)*1000`.
  Three superseded commented-out variants above it apply VAT to the whole price —
  do **not** port those.
- **A large prior port already happened** — see `docs/ADMIN-PORT-PLAN.md` and
  `docs/CHANGELOG-PORT-HISTORY.md` (80 views, 25 Nest modules, 29 Prisma models,
  154 admin routes, 144/144 rids). Prior port notes **no view was ever visually
  verified in a browser**.
- **Stack changed across the port:** Laravel→NestJS/Prisma, Vue2/Vuesax→Vue3/antd.
  Port behaviour, not code style.
- **Reference scale is inflated:** 541 admin `.vue` files but only ~69 reachable
  (rest are Vuexy template demos); 9 reference router files are dead (not imported);
  ~28 legacy Django-era DB tables have no migrations.
- **v1 ⇄ v2 logic gaps** (5, all v2 behind v1) are parity work, not design:
  `ISSUES.md` MON-01, V2-01..05.
