## Overview
#### 1. Repository Role and Entry Points
This is a documentation-first SDLC repository for an enterprise food-delivery platform; it contains no application source, deployable runtime, or infrastructure definitions. The declared status is Product Discovery. Primary navigation begins at `README.md`, then the project governance baseline in `project-management/00_PROJECT_BIBLE.md` and requirements index `docs/02_Requirement_Engineering/SRS/README.md`.
#### 2. Product Discovery and Decision Baseline
Discovery artifacts define the problem space, market context, decisions, and stakeholder outcomes before implementation. These are the upstream inputs to requirements and roadmap planning:
- `docs/01_Product_Discovery/BRD.md`
- `docs/01_Product_Discovery/Competitor_Analysis.md`
- `docs/01_Product_Discovery/Decision_Log.md`
#### 3. System Requirements Architecture
The SRS is the architectural source of truth, organized as introduction, overall description, functional requirements, non-functional requirements, interfaces, and operational constraints. System context, data model, sequence, activity, and state views are maintained as Draw.io artifacts:
- `docs/02_Requirement_Engineering/SRS/02_Overall_Description.md`
- `docs/02_Requirement_Engineering/SRS/diagrams/System_Context_Diagram.drawio`
- `docs/02_Requirement_Engineering/SRS/diagrams/ER_Diagram.drawio`
#### 4. Core Business Capability Flow
The intended customer transaction path is restaurant discovery → menu selection → cart → checkout → payment → order management → delivery. These stages are separately specified, establishing likely future service or bounded-context seams:
- `docs/02_Requirement_Engineering/SRS/functional-modules/03.02_Restaurant_Discovery_Module.md`
- `docs/02_Requirement_Engineering/SRS/functional-modules/03.04_Shopping_Cart_Module.md`
- `docs/02_Requirement_Engineering/SRS/functional-modules/03.05_Checkout_Module.md`
Order fulfillment continues through payment authorization, order state management, and delivery assignment/tracking:
- `docs/02_Requirement_Engineering/SRS/functional-modules/03.06_Payment_Module.md`
- `docs/02_Requirement_Engineering/SRS/functional-modules/03.07_Order_Management_Module.md`
- `docs/02_Requirement_Engineering/SRS/functional-modules/03.08_Delivery_Management_Module.md`
#### 5. Actors and Supporting Domains
The platform covers customer identity/support, delivery-partner operations, restaurant/menu data, reviews, notifications, and administration. Customer-facing ordering is therefore bounded from operational actors and platform-wide capabilities:
- `docs/02_Requirement_Engineering/SRS/functional-modules/03.01_Customer_Module.md`
- `docs/02_Requirement_Engineering/SRS/functional-modules/03.12_Delivery_Partner_Module.md`
- `docs/02_Requirement_Engineering/SRS/functional-modules/03.13_Administrator_Module.md`
#### 6. External Boundaries and Quality Constraints
External integration boundaries are explicitly reserved for software/API/communication interfaces, payment gateways, notifications, and third-party services; specific providers and protocols are not present in the supplied materials. Future runtimes and infrastructure must be selected to meet documented performance, scaling, availability, security, privacy, observability, recovery, and compliance requirements:
- `docs/02_Requirement_Engineering/SRS/external-interface-requirements/05.07_Payment_Gateway_Interface.md`
- `docs/02_Requirement_Engineering/SRS/external-interface-requirements/05.08_Notification_Interface.md`
- `docs/02_Requirement_Engineering/SRS/non-functional-requirements/04.10_Observability.md`
#### 7. Governance, Traceability, and Change Control
Planning flows from discovery and SRS requirements into roadmap, risk, change, and traceability records. The traceability matrices are the control boundary for relating requirements to later engineering and release work:
- `project-management/03_ROADMAP.md`
- `project-management/05_RISK_REGISTER.md`
- `docs/02_Requirement_Engineering/SRS/traceability/Requirement_Traceability_Matrix.md`
