## PART 1 · EXECUTIVE SUMMARY (0.5 PAGE)

### 1A. What We Are Building & Why
- **Pillar 1 — Café Projects, NSO/Renovation CapEx & India Project Site Kiosk (`T1-14` / `BO-PACK-PROJECTS`):** Full coverage of `Master Projects - 2026 to 2027.xlsx` (8 tabs), Site Feasibility (`Rent <= 12%/15%`, `Payback < 24m`, `3-Phase kVA`), 4-Tier Authority (`PRJ-Q2`), 7-Gate NSO pipeline (`Gate 0..Gate 6`), 30 Pre-Opening Checks (`IT-04 ₹0 Variance`), **Dedicated Project Site Kiosk (`Tier 1 Audio/Pictogram + Tier 1.5 Engineer PIN`)** for **(1) Ad-Hoc `Thekedar/Hajiri` Attendance**, **(2) In-Between / Mall Night-Shift (`23:00–05:00`) Check-Ins**, **(3) Visual Site GRN (Challan + E-Way Bill + Lorry Plate + 3-Way Match)**, **(4) Voice/Photo Material Indents**, and **(5) India Ground Controls (Mall Night Permits, UPI Imprest, Hindrance Register, Water TDS `<= 80 ppm` Boiler Gate, Outward Scrap Pass)**.
- **Pillar 2 — Enterprise Fixed Asset Register (`T1-12` — `1,982` QR-Tagged Rows):** Every piece of equipment delivered via a Visual Site GRN (`STAGE_DELIVERED_AT_SITE`) and commissioned at `Gate 6` receives an immutable `HRL-AST-{OUTLET}-{SEQ}` QR tag (`UNIQUE (source_po_line_id, serial_no)`), tracking Purchase Cost, Installation Date, Warranty/AMC Window, Straight-Line/WDV Book Value reconciled to Tally/Odoo, Inter-Outlet Custody Transfers, and the **`40% WDV` Repair-vs-Replace CFO Escalation Gate**.
- **Pillar 3 — 6-State Breakdown Maintenance & CMMS (`T1-13` — ServiceChannel / Paul / Tartine Benchmark):** Outlet crew scan any `HRL-AST-*` QR in `< 15s` to log a breakdown (`P1 Cold-Chain / Deck Oven = 4h SLA`, auto-escalating any critical asset with `MTTR > 24h`). Enforces the **6-State Repair Pipeline (`MAINT-S1`)** where technicians CANNOT self-close tickets—requiring **mandatory 2nd-person Outlet Operator Photo + PIN Verification (`PENDING_OPERATOR_VERIFY -> CLOSED_VERIFIED`, `verified_by_operator_id != assigned_technician_id`)**.

### 1B. Personas & Access Scope
- **Project Site Crew, Site Engineer & HQ Projects Lead (`Pillar 1 — T1-14`)**: Run the Project Site Kiosk (`Ad-Hoc Hajiri, Split/Night Check-In, Visual GRN, Material Indent, Hindrance & Mall Permits`) and advance NSO projects through `Gate 0..Gate 6`.
- **Finance / Asset Controller (`Pillar 2 — T1-12`)**: Audits the `1,982` QR asset register, reconciles WDV book value, approves inter-outlet asset transfers, and adjudicates **`> 40% WDV` Repair-vs-Replace** escalations.
- **Outlet Operator / Shift Manager & Maintenance Vendor (`Pillar 3 — T1-13`)**: Scans QR to raise breakdown tickets (`< 15s`), uploads repair quotes/photos, and performs **2nd-person Operator Verification** before any ticket closes or vendor invoice is paid.

## PART 2 · FULL INTAKE & DOMAIN OBJECT DESIGN (1.5 PAGES)

### 2A. Core User Journeys & Functional Intake Rules

| Journey / Flow | Actor & Trigger | System Action & Hard Gate Rule |
| :--- | :--- | :--- |
| **Pillar 1A (`PRJ-J01..J05`) · Site Feasibility (`PRE->PRJ`), 4-Tier Sanction & 7-Gate NSO** | Projects Lead & CFO -> `POST /api/projects` | Enforces `Rent <= 12%/15%`, `Payback < 24m`, `3-Phase kVA`, `Cannibalization <= 8%`, `PRJ-Q2` 4-tier authority, `Gate 4->5` FSSAI/Fire NOC lock, and `Gate 5` 30 Pre-Opening Checks (`IT-04 ₹0 Variance`). |
| **Pillar 1B (`PRJ-KIOSK-01..06`) · Project Site Kiosk & 5 India Ground Operations** | Site Engineer / Trade Crew -> Project Site Kiosk (`360px`) | Executes **(1) Ad-Hoc `Thekedar/Hajiri` Attendance**, **(2) In-Between / Mall Night-Shift (`23:00–05:00`) Check-Ins**, **(3) Visual Site GRN (Challan + E-Way Bill + Lorry Plate)**, **(4) Voice/Photo Material Indents**, and **(5) Mall Permits, UPI Imprest, Hindrance Register, Water TDS `<= 80 ppm` Boiler Gate & Outward Scrap Pass**. |
| **Pillar 2A (`AST-J01..J02`) · Visual GRN Staging & Idempotent `Gate 6` Asset QR Minting** | Site GRN -> `Gate 6` Handover -> `POST /api/assets/commission-from-project` | When equipment arrives via a Visual Site GRN, it is staged as `STAGE_DELIVERED_AT_SITE`. Upon `Gate 6` completion, it is promoted to `ACTIVE_IN_SERVICE` with a unique `HRL-AST-{OUTLET}-{SEQ}` QR tag (`UNIQUE (source_po_line_id, serial_no)`) and linked to `5–10%` DLP retention. |
| **Pillar 2B (`AST-J03`) · `40% WDV` Repair-vs-Replace CFO Escalation Gate** | Maintenance Lead / CFO -> `POST /api/maint/tickets/{id}/estimate` | Evaluates `(current_repair_estimate_inr + trailing_180d_repairs_inr) > 0.40 * asset_current_wdv_inr`. If exceeded, hard-blocks PO approval (`HTTP 409 WDV_40PCT_CAPEX_REPLACEMENT_GATE`) and routes to CFO for CapEx replacement vs. repair sign-off. |
| **Pillar 3A (`MNT-J01`) · `< 15s` QR Scan-to-Ticket, Warranty Routing & `MTTR <= 24h` SLA** | Outlet Staff -> Scans `HRL-AST-*` QR | Auto-populates Outlet, Asset Make/Model/Serial, and Warranty/AMC status. Active warranty/AMC tickets route directly to OEM vendor at `₹0` labor cost; critical assets (deck ovens, chillers) exceeding `24h` downtime auto-escalate to COO. |
| **Pillar 3B (`MNT-J02`) · 6-State Breakdown Pipeline & Mandatory 2nd-Person Operator Verify** | Technician -> Outlet Operator -> `POST /api/maint/tickets/{id}/verify-close` | Technician uploads repair photo + invoice to enter `PENDING_OPERATOR_VERIFY`. Database constraint `CHECK (verified_by_operator_id <> assigned_technician_id)` requires the Outlet Operator to verify working temperature/status + PIN before `CLOSED_VERIFIED` and vendor payment release. |

### 2B. Underlying Domain Objects & How They Work Together

```text
[Pillar 1: CapexProject (7-Gate NSO + Site Kiosk: Ad-Hoc Hajiri, Split/Night Shift, Visual GRN, Material Indent, Water TDS/Permits)]

```

| Domain Object (`Table`) | Primary Key & Scope | Key Attributes & Constraints | Cross-Object Handshake |
| :--- | :--- | :--- | :--- |
| `CapexProject & SiteKioskOps (projects_capex / site_*)` | `project_id (PK), prj_code` | 7-Gate NSO state, EAC budget, Ad-Hoc `Thekedar` attendance, Split/Night shift spans, Visual Site GRNs, Voice/Photo Material Indents, Mall Permits, Hindrance Register, Water TDS `<=80ppm` | Stages equipment on Visual GRN and auto-commissions `FixedAsset` QRs at `Gate 6`. |
| `FixedAsset (assets_fixed)` | `asset_id (PK), qr_code (UNIQUE), outlet_id` | category, make_model, serial_no, source_po_line_id, purchase_cost_inr, current_wdv_inr, trailing_180d_repair_inr, warranty_until, amc_vendor_id, status | 1,982 QR-tagged assets; enforces `UNIQUE (source_po_line_id, serial_no)` and `40% WDV` guardrail. |
| `RepairTicket (maint_tickets)` | `ticket_id (PK), asset_id (FK), outlet_id` | severity (P1_4H/P2_12H/P3_48H), state (6 states), estimate_inr, wdv_40pct_flagged, assigned_technician_id, verified_by_operator_id, mttr_hours | Enforces 6-state lifecycle and `verified_by_operator_id <> assigned_technician_id`. |

### 2C. State Machines & Operational Guardrails
- **Pillar 1 · 7-Gate NSO + Site Kiosk Ground Ops (`PRJ-S1`)**: Combines 7-Gate NSO governance (`Gate 0..6`, `PRJ-Q2`, `IT-04 ₹0 Variance`) with the **Project Site Kiosk** (`Ad-Hoc Hajiri, Split/Night Check-In, Visual GRN, Material Indent, Mall Permits, Hindrance Register, Water TDS <= 80 ppm`).
- **Pillar 2 · `1,982` Asset QR Lifecycle & `40% WDV` Gate (`AST-S1`)**: <code>STAGE_DELIVERED_AT_SITE</code> (Visual GRN) &rarr; <code>ACTIVE_IN_SERVICE</code> (Gate 6 QR) &rarr; <code>UNDER_REPAIR</code> / <code>INTER_OUTLET_TRANSFER</code> &rarr; <code>40PCT_WDV_CFO_GATE</code> &rarr; <code>CONDEMNED_DISPOSED</code>
- **Pillar 3 · 6-State Breakdown Pipeline (`MAINT-S1`)**: <code>1_REPORTED</code> &rarr; <code>2_TRIAGED_ASSIGNED</code> &rarr; <code>3_WORK_IN_PROGRESS</code> &rarr; <code>4_PENDING_PARTS_OR_WDV</code> &rarr; <code>5_PENDING_OPERATOR_VERIFY</code> &rarr; <code>6_CLOSED_VERIFIED</code>
- **Cross-Pillar Financial & Operational Locks**: 1. No vendor PO payment without Visual Site GRN. 2. No equipment energization without `Water TDS <= 80 ppm` & `DISCOM kVA`. 3. No repair PO `> 40% WDV` without CFO sign-off. 4. No repair payment without 2nd-person Operator verify.

### 2D. Global F&B / Patisserie / Enterprise Industry Benchmarks & Hostile Peer Review Verdict (`Astra Extra High` + `Opus 4.7 Extra High`)

| Global Benchmark / Peer Reviewer | Standard / Gate Adopted | How Harley's OneOps / HOP Enforces It |
| :--- | :--- | :--- |
| **Pillar 1 — Starbucks / Procore / Powerplay India Café Projects (`T1-14`)** | **Site Feasibility (`PRE->PRJ`), 7-Gate NSO, Project Site Kiosk (`Ad-Hoc Hajiri, Split/Night Shift, Visual GRN, Voice Indent`) & 5 India Ground Realities (`6A–6E`)** | Full `Master Projects - 2026 to 2027.xlsx` coverage: `Rent <= 12%/15%`, `Payback < 24m`, `3-Phase kVA`, Separate Sanction/PO/Invoice/Bank authority (`PRJ-Q2`), 30 Pre-Opening Checks (`IT-04 ₹0 Variance`), and Gate 6 auto-commissioning into the Fixed Asset Register. |
| **Pillar 2 — Enterprise Fixed Asset Lifecycle (`T1-12`)** | **`1,982` QR-Tagged Assets, Depreciation & `40% WDV` Gate** | Every deck oven, blast chiller, espresso machine, and POS terminal carries a tamper-proof `HRL-AST-{OUTLET}-{SEQ}` QR code, Make/Model/Serial, Warranty/AMC window, Straight-Line/WDV book value, and a hard **`40% WDV` Repair-vs-Replace CFO Escalation Gate**. |
| **Pillar 3 — ServiceChannel / Fiix F&B CMMS (`T1-13`)** | **`< 15s` QR Scan-to-Ticket, MTBF/MTTR & 6-State 2nd-Person Verify** | Outlet staff scan an asset QR to file a breakdown (`P1 Cold-Chain/Oven = 4h SLA`) in `< 15s`; tracks **MTBF / MTTR** per equipment model; enforces `MAINT-S1` 6-state pipeline where vendors/technicians CANNOT self-close tickets—mandatory **2nd-person Outlet Operator Photo + PIN Verification (`PENDING_OPERATOR_VERIFY -> CLOSED_VERIFIED`)**. |
| **Astra XHigh + Opus 4.7 Remediation Applied** | **Paul/Poilâne/Tartine Critical Asset MTTR <= 24h + 2nd-Person DB Constraint** | Added `MTTR > 24h` auto-escalation on critical patisserie assets (deck ovens, proofers, spiral mixers, blast chillers), EAC CapEx reconciliation, and DB constraint `CHECK (verified_by_operator_id <> assigned_technician_id)`. |
| **Hostile Peer Review Verdict (`Astra XHigh` + `Opus 4.7`)** | **✅ APPROVED — BALANCED 3-PILLAR ARCHITECTURE** | Verified equal weight across Pillar 1 (Café Projects NSO/CapEx), Pillar 2 (1,982 Fixed Assets), and Pillar 3 (6-State Breakdown Maintenance) with deterministic handshakes. |

### 2F. Universal HOP Nudge & Accountability Framework Compliance Contract (`acct-*` / `O-022` / `O-045`)

| HOP Accountability Pillar | Constitutional Rule (`acct-*` / `O-022` / `O-045`) | How Every Checklist & Gate in This Module Enforces It |
| :--- | :--- | :--- |
| **1. Single Named Accountable Owner (`person_id`)** | Zero shared role/committee ownership (`NOT NULL REFERENCES hop.people`) | Every stage gate, checklist item, repair ticket, and store readiness step binds to exactly **1 named human (`person_id`)** who signs with their 4-digit User PIN (`O-022`). |
| **2. Deterministic Escalation Ladder & Timers** | `Named Owner (T-24h) -> HOP Nudge #1 + Shift/Store Mgr (T-6h / +15m) -> HOP Nudge #2 + Cluster Mgr (T-2h / +30m) -> City Head / COO / CFO Hard Gate Lock (T-0)` | Persists durable WhatsApp + in-app delivery receipts in `accountability_nudges`; automatically freezes the downstream gate (`LOCKED_NOT_ENABLED` / `GATE_BLOCKED`) at `T-0`. |
| **3. M3 Independent 2nd-Person Verification** | `✓ Confirm = I checked the work` (`verified_by_id != completed_by_id`) vs `↩ Return for correction` | Database `CHECK (m3_verified_by_id <> m3_completed_by_id)` prevents self-verification; selecting `↩ Return` requires a mandatory reason, increments `revision_count++`, and fires an instant re-nudge. |
| **4. Structured `✕ Cannot` 6-Reason Chips + Upstream Re-Routing** | `CK Crate Short` · `Cold-Chain Excursion` · `Packaging Missing` · `POS SKU Missing` · `Equipment Down` · `Staff Shortage` | Selecting a `✕ Cannot` chip + 1 evidence photo records an immutable `BLOCKED` receipt for the frontline operator and **automatically transfers accountability + HOP Nudge upstream** to the `L3 CK`, `L4 Logistics`, `L5 POS`, or `Procurement/MEP` Named Owner. |
| **5. Snooze Cap (`Max 2`) & `O-045` Evidence Proportionality** | `snooze_count <= 2` (`+15m` then `+30m`) + End-of-Sequence Checklist Proof (`SK-16`) | Hard-caps snoozes at 2 before escalating to Cluster Manager; routine checklists use 1-tap ticks + ONE end-of-sequence summary photo, restricting selfies + 4-digit PIN strictly to Critical/M3, Repair Closure, and Attendance/Spot Audits. |
