## Overview

#### Purpose and Scope
This repository currently contains product-definition material rather than an implemented application. The primary artifact is `PRD.md`; supporting external-reference notes live under `references/`.

#### Entry Points
There are no executable entry points, services, packages, or runtime manifests in the supplied tree. Work should begin from the requirements in `PRD.md`.

#### Product Requirements Boundary
`PRD.md` is the authoritative source for intended behavior, user flows, domain rules, and acceptance criteria. It should drive subsequent implementation decomposition and architecture decisions.

#### Reference Material
The `references/paprika/` subtree isolates notes related to Paprika rather than mixing them into the core product document:
- `references/paprika/paprika_url.md`

This indicates Paprika URLs may be an external integration, import/export format, deep-link target, or compatibility constraint; its exact role must be established from the referenced document before designing that boundary.

#### Intended Architecture Stages
No concrete source modules exist yet. A future implementation will likely need to separate:
1. Requirement-derived application/domain behavior from `PRD.md`.
2. Paprika-specific URL parsing, generation, or integration logic based on `references/paprika/paprika_url.md`.
3. Any application interface, persistence, API, or deployment layers implied by the PRD.

#### Data and Control Flow
The only visible flow is documentation-driven: product requirements in `PRD.md` define the system, while Paprika URL semantics in `references/paprika/paprika_url.md` constrain an external-format boundary. No implemented data stores, APIs, queues, authentication systems, cloud infrastructure, or third-party SDKs are present.

#### Current Architectural Constraints
Treat the repository as pre-implementation. Do not infer a web, mobile, CLI, or backend runtime from the tree alone. Before adding code, extract explicit actors, entities, workflows, integration direction, and nonfunctional requirements from `PRD.md`, then define an adapter boundary around Paprika URL behavior.

Main entry points: [`PRD.md`](https://github.com/tomfromtomsk/rhiori/blob/dev/PRD.md) (Product requirements), [`references/paprika/paprika_url.md`](https://github.com/tomfromtomsk/rhiori/blob/dev/references/paprika/paprika_url.md) (Paprika URL notes)

## Components

### Product Definition

Authoritative inputs for implementation planning.

- [Product requirements](https://github.com/tomfromtomsk/rhiori/blob/dev/PRD.md): requirements document · Defines intended behavior, flows, rules, and acceptance criteria. · `PRD.md`

### External Format Boundary

Paprika-specific compatibility material.

- [Paprika URL notes](https://github.com/tomfromtomsk/rhiori/blob/dev/references/paprika/paprika_url.md): reference document · Defines URL semantics that must be clarified before integration design. · `references/paprika/paprika_url.md`
- **Paprika URL adapter**: future integration boundary · Parsing, generation, or compatibility logic determined from the reference notes.

### Future Implementation

Architecture to be derived before code is added.

- **Requirements analysis**: planning stage · Extract actors, entities, workflows, integrations, and nonfunctional requirements.
- **Domain behavior**: future application layer · Requirement-derived product rules and workflows.
- **Application layers**: future architecture · Interface, API, persistence, and deployment choices only where required by the PRD.
