Portfolio Hub Interface Contract

• Baseline Mode: observed
• Baseline Seed: .stagepilot/bootstrap/baseline.yaml
• Status: confirmed
• Owner: repository-maintainers
• Last Updated (KST): 2026-05-21 00:00
• Source Discovery / Batch: bootstrap-baseline, bat-001, bat-006, bat-008, bat-010, bat-003, bat-004, bat-005, BAT-006(dcy-004), BAT-007(dcy-004), BAT-008(dcy-004)
• Primary Runtime: mixed

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.

Purpose

• This document captures the approved external and cross-boundary interface contracts for the project.
• It is a cross-cutting reference for REQ drafting, batch design, implementation, verification, and handoff.

Scope

• Covers externally visible APIs, CLI surfaces, events, files, or batch I/O contracts.
• Does not duplicate full business requirements already owned by REQ documents.
• Does not replace low-level code references or generated API artifacts.

Interface Summary

• Primary HTTP API :: manage authentication, portfolios, strategy sets, and users over JSON HTTP endpoints
• PortfolioHub CLI :: provide command-line access to health checks, database setup, users, portfolios, strategies, and service tokens

Interface: Primary HTTP API

• Type: http-api
• Consumers / Producers: authenticated clients, operators, and downstream services
• Purpose: manage authentication, portfolios, strategy sets, and users over JSON HTTP endpoints
• Stability: internal

Inputs

• Authorization: Bearer :: required for protected routes and mapped to read, trade-write, or admin permissions
• JSON request bodies :: carry login, token issuance, user CRUD, strategy-set CRUD, portfolio mutations, comments, and tags
• Route and query parameters :: select users, tokens, portfolios, filters, recent history windows, comments, and tags

Outputs

• JSON response models :: responses are shaped by app/schemas/auth.py, app/schemas/user.py, and app/schemas/portfolio.py
• HTTP 201, 200, and 204 status codes :: create, read or update, and delete semantics respectively
• GET /health payload :: returns {"status": "ok", "service": "portfolio-hub", "version": "<semver>", "checked_at": "<ISO8601 KST>", "db_enabled": <bool>} for readiness checks. db_enabled exposes the PORTFOLIOHUB_DB_ENABLED setting value (not an actual DB connectivity ping); see docs/runtime-flows.md for the readiness semantics (REQ-035, dcy-005).

Error Contract

• 401 Unauthorized :: invalid credentials, invalid token, or missing token on protected routes
• 403 Forbidden :: insufficient permission or token issuance policy violation
• 404 Not Found :: missing user, token, portfolio, comment, tag, or strategy set
• 422 Unprocessable Entity :: FastAPI or Pydantic request validation failure

Compatibility Rules

• Route prefixes /health, /auth, /users, /strategy-sets, and /portfolios define the current internal API surface.
• Permission semantics read, trade-write, and admin must stay aligned across auth guards and token metadata.
• Breaking route or schema changes require REQ and Batch documentation updates before release.

Interface: PortfolioHub CLI

• Type: cli
• Consumers / Producers: operators and automation
• Purpose: provide command-line access to health checks, database setup, users, portfolios, strategies, and service tokens
• Stability: internal

Inputs

• pfhub subcommands :: include user, portfolio, strategy, tag, service-token, daemon, credential, health-check, init-db, and migrate-db command families
  • service-token subcommands: issue, rotate, rebind (BAT-007: --daemon-id 변경), revoke, list, migrate-null-daemon --dry-run (BAT-007: NULL daemon_id 진단 CLI)
  • daemon subcommands: create, list, update (BAT-007: --deactivate --force 시 바인딩 service token 자동 revoke)
• Flags and options :: include --format table|json, --force confirmations, and operation-specific mutation arguments
• Environment configuration :: app/core/config.py resolves PORTFOLIOHUB_* and TIMESCALEDB_* values before command execution
• Portfolio identification (bat-006) :: all portfolio mutation commands accept <name> (positional) + --user <username> instead of raw portfolio_id; comment sub-commands accept portfolio_id (UUID) directly
• Tag commands (bat-005) :: pfhub tag create/list/deactivate/apply/remove operate on the tags master table; pfhub portfolio tag add/list/remove has been removed (breaking change)

Outputs

• Table or JSON console rendering :: read flows emit structured operator output suitable for manual review or automation
• One-time token reveal :: issued client or service tokens are shown once and then only masked metadata remains
• Process exit status :: command success or failure is communicated through standard CLI exit behavior

Error Contract

• Typer validation errors :: invalid arguments or missing required options stop the command before execution
• Confirmation refusal :: write commands abort unless the operator confirms or passes --force
• Persistence and auth failures :: disabled DB mode, connectivity issues, or permission problems surface as command errors

Compatibility Rules

• Command names and primary flags should remain stable for internal automation.
• Write commands require explicit confirmation unless --force is present.
• JSON output should remain machine-readable across additive command evolution.

Interface: v1 Consumer API (trex-basic)

• Type: http-api
• Consumers / Producers: trex-basic service (Consumer-Driven Contract, dcy-002, dcy-006)
• Purpose: provide daemon-scoped asset listing, user info with daemon_id diagnostic, and daemon-assignment-authorized trade ledger recording
• Stability: internal (versioned under /v1)

Authentication

• All /v1 endpoints require Authorization: Bearer <token> header.
• Token must be DB-issued (token_source="db"); env tokens are rejected with HTTP 403.
• Admin catalog endpoints (POST /v1/assets, PATCH /v1/assets/{id}, PATCH /v1/assets/{id}/deactivate) require admin permission.
• POST /v1/portfolios/{portfolio_id}/ledger/trades additionally requires trade-write permission and a DB service token with non-NULL daemon_id.

Token Type Branching

• token_type="service": daemon-scoped endpoints. daemon_id must be non-NULL (NULL → HTTP 403 fail-closed).
• token_type="session": user-scoped (login token). Endpoints return owner's own data.
• token_type="client": Deprecated/Removed (REQ-016/BAT-006). 발급 경로 제거. 잔존 DB row는 읽을 수 있으나 신규 발급 불가. v1 API 호출 시 HTTP 403 fail-closed.
• env token (token_source="env"): admin-scoped. May query other users' data via ?user_id=<id> param. DB /v1 endpoints에서는 HTTP 403 (DB token만 허용).

Daemon Authorization Model

• Service tokens are bound to a daemon at issuance via daemon_id field. Legacy/unbound tokens have daemon_id=NULL.
• GET /v1/assets (service token) and POST /v1/portfolios/{portfolio_id}/ledger/trades are daemon-scoped. NULL token daemon_id → HTTP 403 (fail-closed).
• GET /v1/user_info is available to any service token; returns daemon_id: null as diagnostic for unbound tokens.
• Each asset (portfolio) may be assigned to exactly one daemon via portfolios.managed_by_daemon_id. Mismatch or unassigned asset → HTTP 403 on ledger writes.
• Token rebind (BAT-007/REQ-023): pfhub service-token rebind <name> --daemon-id <id> — daemon_id 변경, runtime_id 불변. 대상 daemon은 active이어야 하고 token 소유 user와 일치해야 한다.
• Daemon deactivation (BAT-007/REQ-022): pfhub daemon update <daemon_id> --deactivate --force — daemon is_active=false + 바인딩된 모든 service token 즉시 revoke.
• NULL daemon migration CLI (BAT-007/REQ-023): pfhub service-token migrate-null-daemon --dry-run — NULL daemon_id active service token inventory 출력 + user별 candidate daemon 목록. --dry-run 없이 실행 시 exit code 1 + 수동 안내.

Endpoint: GET /v1/assets

• Auth: DB token required; behavior branches by token_type
  • service: returns portfolios where managed_by_daemon_id = token.daemon_id; NULL daemon_id → 403
  • user: returns caller's own portfolios (owner_user_id = token.user_id)
  • admin: returns caller's own portfolios; ?user_id=<id> overrides to specified user
• Query Params: ?status=<value> (optional portfolio status filter), ?market=<code> (optional market code filter), ?user_id=<id> (admin only)
• Response: HTTP 200

}

• Error: HTTP 401 if no token; HTTP 403 if not a service token

Endpoint: POST /v1/assets/{asset_id}/ledger/trades

• Auth: service-token bearer (trade-write); token must have daemon_id bound; asset must be assigned to that daemon
• Path Param: asset_id — must be a valid UUID portfolio_id
• Authorization: portfolios.managed_by_daemon_id must equal token.daemon_id; NULL token → 403; unassigned asset → 403; mismatch → 403

  "recorded_at": "<ISO8601|null>",
  "status": "new"
}

• Response HTTP 200 (idempotent duplicate with identical payload): same body with "status": "duplicate"
• Error: HTTP 401 if no token; HTTP 403 if not service token, daemon_id NULL, asset unassigned, or daemon mismatch; HTTP 404 if asset_id not found; HTTP 409 if duplicate key with different payload

Idempotency Contract

• Deduplication key: (asset_id, order_id, execution_id) — enforced by uq_ledger_trades_idempotency DB unique constraint
• Identical payload re-send → HTTP 200 + status="duplicate", no new row created
• Same key, different payload → HTTP 409 Conflict

Deployment Constraint (bat-006)

• trex-basic and portfolio-hub must be deployed simultaneously when BAT-006 is released.
• After BAT-006, all asset_id values in GET /v1/assets responses change from TEXT to UUID format.
• trex-basic consumers must handle UUID-format asset_id before the coordinated deployment is completed.

Interface: v1 Portfolio API (BAT-009/010)

• Type: http-api
• Consumers / Producers: authenticated users and admin services
• Purpose: CRUD for user-owned portfolios; tag and comment sub-resources; ownership and disabled-state enforcement
• Stability: internal (versioned under /v1)

Authentication

• All /v1/portfolios endpoints require Authorization: Bearer <token> header.
• token_type ∈ {service, client} → HTTP 403 fail-closed for all write operations and GET sub-resources.
• permission='admin' → access to all portfolios. permission ∈ {read, trade-write} → own portfolios only.
• Comment and portfolio CRUD routes: DB token or env token; POST/PATCH/DELETE require user or admin token type.
• Tag POST/DELETE routes additionally require token_source="db" (DB token).

Endpoint: POST /v1/portfolios

• Auth: any valid token; service/client → HTTP 403
• Body: {"asset_id": "<uuid>", "broker": "<str>", "name": "<str|null>", "cash_balance": <float>, "asset_quantity": <float>, "asset_price": <float>, "profit_buffer": <float>, "strategy_name": "<str|null>", "strategy_params": {<dict>}, "managed_by_daemon_id": "<str|null>", "user_id": "<str|null> (admin only)"}
• Response: HTTP 201 PortfolioItem {"portfolio_id": "<uuid>", "asset_id": "<uuid>", "symbol": "<assets.symbol|null>", "owner_user_id": "<str|null>", "broker": "<str>", "status": "<str>", "name": "<str>", ...}
• Note: symbol is populated from the server-side joined asset row (portfolios.asset_id -> assets.asset_id -> assets.symbol), not from client-side catalog reconstruction.
• Error: HTTP 422 if asset not found or inactive; HTTP 403 if service/client token

Endpoint: PATCH /v1/portfolios/{portfolio_id}

• Auth: any valid token; service/client → HTTP 403; ownership required
• Body: {"broker": "<str|null>", "status": "<str|null>", "name": "<str|null>", "strategy_name": "<str|null>", "strategy_params": {<dict|null>}, "asset_price": <float|null>, "managed_by_daemon_id": "<str|null>"}
• Response: HTTP 200 PortfolioItem {"portfolio_id": "<uuid>", "asset_id": "<uuid>", "symbol": "<assets.symbol|null>", ...}
• Note: response symbol is emitted from the joined asset row referenced by asset_id.
• Error: HTTP 403 if service/client or ownership mismatch; HTTP 404 if portfolio not found; HTTP 409 if portfolio is disabled and non-status fields are provided

Endpoint: DELETE /v1/portfolios/{portfolio_id} (Soft Delete)

• Auth: any valid token; service/client → HTTP 403; ownership required
• Body: none
• Response: HTTP 200 PortfolioItem with status="disabled", managed_by_daemon_id=null, symbol="<assets.symbol|null>"
• Note: soft delete does not break the asset join; symbol remains the linked assets.symbol value in the HTTP 200 response.
• Dependent data: portfolio_comments and tag_ids are preserved on soft delete; only status and daemon assignment change
• Error: HTTP 403 if service/client or ownership mismatch; HTTP 404 if not found

Endpoint: GET /v1/portfolios

• Auth: any valid token; client → HTTP 403
• Query Params: ?include_disabled=true (default false); ?market=<code>; ?user_id=<str> (admin only)
• Branching by token type:
  • service: returns portfolios where managed_by_daemon_id = token.daemon_id; NULL daemon_id → HTTP 403
  • user/admin: returns owner's own portfolios; admin may override with ?user_id=<id>
• Response: HTTP 200 PortfolioListResponse {"portfolios": [{"portfolio_id": "<uuid>", "asset_id": "<uuid>", "symbol": "<assets.symbol|null>", "net_contributed_capital": <float>, "cumulative_profit_withdrawn": <float>, ...}], "total": <int>}
• Note: list items are serialized from the server-side portfolios JOIN assets result; symbol must equal the joined assets.symbol for each returned asset_id.
• Ledger aggregate fields:
  • net_contributed_capital (순투자현금) = 유효 manual INVEST 합계 - 유효 manual WITHDRAW 합계.
  • cumulative_profit_withdrawn (누적 수익 인출액) = 유효 manual PROFIT 합계. 매매상 실현손익 전체가 아니다.
  • REVERSAL.target_ledger_entry_id로 참조된 INVEST, WITHDRAW, PROFIT 원거래는 유효 집계에서 제외하며 REVERSAL 자체는 금액 action으로 합산하지 않는다.
  • 목록에 반환될 portfolio ID 집합만 한 번의 grouped aggregate로 조회한다. 해당 유효 manual ledger가 없는 항목은 두 필드 모두 0.0이다.
  • 이 필드들은 portfolio-hub가 소유한 ledger 집계값이다. 소비자는 ledger event를 재해석하지 않는다.

Endpoint: GET /v1/portfolios/{portfolio_id}/tags

• Auth: DB or env token; service/client → HTTP 403; ownership required

• Route POST /auth/tokens 및 CreateClientTokenRequest / IssuedClientTokenResponse 스키마 제거. 호출 시 HTTP 404 또는 405.
• token_type="client" 발급 경로는 코드에서 완전히 제거됨. 잔존 client token row는 DB에 읽기 전용으로 남을 수 있음.

POST /auth/service-tokens Body — daemon_id 추가 (BAT-006/REQ-018)

• Body daemon_id 필드가 서비스 토큰 발급 시 라우트 핸들러로 정상 forwarding됨. (이전: 누락으로 인해 daemon_id가 항상 NULL로 저장)
• Body: {"name": "<str>", "username": "<str>", "permission": "read|trade-write", "expires_in_days": <int|null>, "no_expiry": <bool>, "daemon_id": "<uuid|null>"}
• Response: HTTP 201 {"token": "<raw>", "runtime_id": "<str>", "daemon_id": "<str|null>", ...}

Token Issuance Authorization Matrix

(REQ-020/BAT-008 — dcy-004 FR-5, NFR-4)

매트릭스 위반 호출 → HTTP 403 fail-closed (모든 권한 미충족 케이스).

Token Type	Verb	admin	trade-write	read	비고
session	issue (POST /auth/login)	✓	✓	✓	유효 credential 필요
session	revoke (DELETE /auth/tokens/{id})	✓ 본인	✓ 본인	✓ 본인	타 user token 폐기 불가
session	list (GET /auth/tokens)	✓ 본인	✓ 본인	✓ 본인	—
service	issue (POST /auth/service-tokens)	✓	✗	✗	admin만 발급 가능
service	rotate (pfhub service-token rotate)	✓	✗	✗	CLI only
service	rebind (pfhub service-token rebind)	✓	✗	✗	CLI only
service	revoke (pfhub service-token revoke)	✓	✗	✗	CLI only
service	list (pfhub service-token list)	✓	✗	✗	CLI only
env	issued/managed	infra operator	✗	✗	PORTFOLIOHUB_ADMIN_TOKENS 환경 변수 직접 편집
client	—	✗	✗	✗	폐지됨 (REQ-016/BAT-006)

Admin 자기 발급 정책 (dcy-004 OQ-4): admin은 본인 user_id 대상으로 daemon-bound 또는 unbound service token 발급 가능. 관행상 최소 권한 원칙에 따라 운영 daemon 대상 발급을 권장.

코드 매핑: require_admin → admin 전용 게이트. require_read → read 이상 허용. AuthService.issue_service_token() → admin 권한 필요 (라우트에서 require_admin 의존성). 불일치 발견 시 별도 follow-up REQ로 분리.

Shared Constraints

• Token permission levels gate both HTTP and CLI mutations consistently.
• DB-backed endpoints and commands require PORTFOLIOHUB_DB_ENABLED=true plus valid TimescaleDB settings.
• Secret and token values are only revealed once at issuance time and are masked afterwards.

Current Gaps / Planned Changes

• External consumer versioning policy is still implicit and not published as a separate contract artifact.
• Service-token lifecycle and ownership rules may continue to evolve as authorization requirements mature.
• OpenAPI publication and CLI reference generation are not yet automated.

Update Triggers

• Update this document when an externally visible API, event, CLI, or file contract changes.
• Update this document when a batch changes compatibility, validation, or error behavior.
• Update this document when a new external consumer or producer is introduced.
