Portfolio Hub Project Structure

• Baseline Mode: observed
• Baseline Seed: .stagepilot/bootstrap/baseline.yaml
• Status: confirmed
• Owner: repository-maintainers
• Last Updated (KST): 2026-04-30 22:13
• Source Discovery / Batch: bootstrap-baseline

Project Summary

• PortfolioHub exposes portfolio management and trading ledger workflows through a FastAPI service and a companion CLI.

Primary Domain

• Portfolio management and trading ledger services.

Tech Stack

• Python 3.12
• FastAPI
• Typer
• Pydantic Settings
• Psycopg
• Alembic
• PostgreSQL/TimescaleDB
• Docker Compose

Primary Runtime

• Type: mixed
• Planned Entry Points:
• uvicorn app.main:app :: serve the authenticated HTTP API, OpenAPI docs, and startup bootstrap hooks
• pfhub :: run operational CLI commands for health, users, portfolios, strategies, and service tokens
• alembic upgrade head :: apply ordered database schema migrations for persistent environments

Purpose

• This document is the current approved repository and package structure baseline.
• It is a cross-cutting reference document for Discovery, REQ, Batch Design, Batch Verification, and implementation updates.

Scope

• Covers the top-level repository layout and package or module boundaries.
• Does not duplicate detailed business rules, acceptance criteria, or implementation-only function signatures.

Package / Module Responsibilities

• .github/
  • Hosts StagePilot skills, document templates, and helper scripts such as stagepilot-doctor and stagepilot-bootstrap-seed.
• app/api/
  • Defines FastAPI route surfaces for health, authentication, users, strategy sets, and portfolios.
• app/cli/
  • Defines the Typer entrypoint, command groups, output helpers, and operator-facing command flows.
• app/core/
  • Owns configuration loading, auth guards, security helpers, and shared error handling.
• app/domain/
  • Holds framework-light domain models shared by services, routes, and repositories.
• app/repositories/
  • Provides the repository protocol, repository factory, and concrete Postgres persistence implementation.
• app/schemas/
  • Defines request and response schemas for HTTP contracts.
• app/services/
  • Implements business logic for auth, portfolios, strategy sets, and users.
• migrations/
  • Stores Alembic environment files and ordered schema revisions for persistent database changes.
• tests/
  • Covers API behavior, auth flows, CLI behavior, domain services, portfolio comments, tags, ownership, and users.
• docs/
  • Stores active SDLC indices and cross-cutting baseline documents.

Dependency Rules

• Interface layers in app/api/ and app/cli/ should reach persistence through app/services/ and app/repositories/factory.py rather than importing database code directly.
• app/domain/models.py remains the shared contract between services, repositories, and interface adapters.
• app/repositories/postgres.py owns SQL details; migrations/versions/ owns ordered schema evolution history.
• app/core/config.py is the shared configuration source for both the FastAPI app and the Typer CLI.
• tests/ should prefer public API, CLI, or service entrypoints over asserting against private persistence details unless a regression requires it.

Shared Boundaries

• PortfolioRepository is the abstraction boundary between business logic and concrete persistence.
• Settings and auth primitives are shared across API requests, CLI commands, and startup bootstrap behavior.
• docs/ holds SDLC source-of-truth artifacts, while temp/ remains scratch or legacy material outside the active document flow.
• .vendor/stage-pilot/ is a vendored upstream toolkit and should not be treated as the active host source of truth.

Current Gaps / Planned Changes

• No active Discovery, REQ, Batch, or Release units exist yet; this baseline only bootstraps the document structure.
• The non-DB repository path intentionally raises a feature-not-ready error when persistence is disabled.
• Redis and Loki settings exist, but their runtime ownership and module boundaries are not yet represented in active docs.

Update Triggers

• Update this document when package boundaries change.
• Update this document when new top-level runtime or domain modules are added.
• Update this document when a batch changes the approved structure baseline.

Change Log

• 2026-04-30 KST: Bootstrap baseline created from repository observation for initial StagePilot adoption.
