Document Transcription System Requirements (Version 4)
This document defines the baseline requirements for the document transcription system.
Requirements Model
| ID | Category | Requirement | Verify Method |
|---|---|---|---|
| REQ-0 | System | Provide end-to-end multi-page document transcription with persistent, inspectable async job states. | demonstration |
| REQ-1 | Functional | Allow users to upload one or more images as ordered Source pages under a Document. |
test |
| REQ-2 | Functional | Process page transcription asynchronously using an asyncio worker pool bounded by rate limits. |
test |
| REQ-3 | Functional | Persist submission-time request provenance and accurately labeled page-level SDK evidence; V4.2 adds exact OpenRouter-boundary transport evidence for new attempts. | test |
| REQ-4 | Functional | Support job states queued, processing, completed, partial_success, and failed, plus page states pending, transcribed, and failed. |
inspection |
| REQ-5 | Functional | Allow users to manage historical Person records and link multiple people per role to a Document. |
test |
| REQ-6 | Functional | Support an extensible role taxonomy for document-person relationships. | inspection |
| REQ-7 | Policy Constraint | Enforce deterministic relationship-role writes with uniqueness on (document_id, person_id, role_id) and explicit conflict responses for invalid duplicate link attempts. |
test |
| REQ-8 | Functional | Use set-based synchronization for document-person mutations so updates add and remove only the intended links. | test |
| REQ-9 | Functional | Maintain immutable machine output on Source.raw_transcription while permitting inline human edits on Source.revised_text. |
test |
| REQ-10 | Functional | Support a UUID-identified DocumentType taxonomy with unique user-facing labels and active/inactive lifecycle control. |
test |
| REQ-11 | Data Constraint | Store Document type as a controlled reference to DocumentType. |
test |
| REQ-12 | Interface | Render multi-page transcriptions sequentially by page_number with document, people, and document-type metadata. |
demonstration |
| REQ-13 | Interface | Document create/edit UI must support selecting multiple people per role and selecting an active document type from the registry. | demonstration |
| REQ-14 | API Constraint | Expose additive, role-aware retrieval and write behavior for document-person links and UUID-based selection for document types. | test |
| REQ-15 | Data Constraint | Calculate and store cryptographic file hashes (SHA-256) and file sizes for uploaded source images. | test |
| REQ-16 | Data Constraint | Preserve a portable relational model across supported backends using SQLModel, SQLAlchemy, SQLite, and PostgreSQL. | inspection |
| REQ-17 | Reliability | Ensure delete and update flows for documents, people, and relationship links remain deterministic and safe. | test |
| REQ-18 | Operations Constraint | Keep canonical development, testing, restore, and recovery workflows OS-independent; for AI-run unit tests, require a pre-test backup of ./data and an always-shown post-success confirmation prompt before any restore action. |
inspection |
| REQ-19 | Quality | Provide automated coverage for async transcription workflows, relationship-role enforcement, document-type selection, and regression behavior. | test |
Clarifying Constraints
DocumentType.idis its sole identity; labels are unique ignoring case and surrounding whitespace.PersonRole.codeis a stable machine identifier;PersonRole.labelmay evolve.- Relationship-write policy and conflict handling must be consistent across UI, API, services, and persistence.
- Many-per-role behavior is required for document-person links.
- Relationship conflicts must fail deterministically without partial mutation.
Element Satisfaction Mapping
- UI (NiceGUI): Satisfies REQ-0, REQ-1, REQ-5, REQ-9, REQ-12, REQ-13.
- API (FastAPI): Satisfies REQ-1, REQ-4, REQ-5, REQ-7, REQ-8, REQ-14.
- Worker (
asyncio): Satisfies REQ-2, REQ-3, REQ-4. - Persistence (SQLModel / SQLAlchemy): Satisfies REQ-3, REQ-9, REQ-10, REQ-11, REQ-15, REQ-16, REQ-17.
- Test Suite: Verifies all test-marked requirements and satisfies REQ-19.
