# POTS Workspace Phase 6 - Intake Progress Model

## Goal
Track answer-state progress across intake questions and compute completion by section and overall.

## Data Model
- Question status enum:
  - `answered`
  - `unknown`
  - `deferred`
  - `needs_owner`
- Payload model:
  - `questions[]` with `question_id`, `section_id`, `status`
- Persisted project fields:
  - `progress_questions`
  - `progress_summary.sections`
  - `progress_summary.overall`

## API
- `POST /api/pots_workspace/projects/{project_id}/progress`
  - accepts progress payload.
  - computes section and overall completion percentages.
  - sets lifecycle from `draft` -> `discovery` when progress entries are first added.

## Completion Formula
- `completion_pct = answered / total * 100`
- Calculated per section and overall.

## Verification
- `python3 -m pytest -q backend/app/test_pots_workspace_api.py`
  - includes progress-summary regression test.
