feat: scaffold Week 6 assignment (Deploy to Azure)

[lassebenni]

Summary

• Replaces the empty task-1 / task-2 placeholder stubs with a real scaffold derived from Data Track/Week 6/week_6__8_assignment.md.
• Students build a Container App Job pipeline that uploads raw JSON to Azure Blob Storage and upserts rows into Azure Database for PostgreSQL, then verify the deployment with an Execution-history screenshot.
• Auto-grader verified end-to-end against a local working solution: scaffold = 13/100 (pass=false), working solution = 100/100 (pass=true).

Why static analysis (no live Azure check)

The Week 6 assignment requires live Azure resources (Storage Account, Postgres flexible server, ACR, Container Apps environment) that the GitHub Actions runner cannot reach without credentials. The grader therefore verifies code shape, not deployment success: the patterns Chapters 3-5 teach (env-var reads, contextlib.closing(), the ON CONFLICT ... DO UPDATE upsert, sslmode=require, BlobServiceClient usage, the azure SDK logger silencing) plus the artefact deliverables (AI report, Execution-history screenshot, README Verification section).

Scoring ladder (100 pts total, passing 60)

Points	Level	What the grader checks
10	1	Required files exist (Dockerfile, requirements.txt, src/pipeline.py, AI_ASSIST.md, README.md, docs/)
10	2	requirements.txt pins azure-storage-blob AND psycopg2-binary (5 pts each)
10	3	Dockerfile uses python:3.11 base, copies requirements before src, has a real CMD (3 + 5 + 2)
15	4	pipeline.py reads both env vars (5), wraps with closing() (5), silences azure logger (5)
15	5	pipeline.py has ON CONFLICT ... DO UPDATE (10) and %s placeholders inside execute(...) (5)
10	6	Repo mentions sslmode=require (5) and pipeline imports BlobServiceClient (5)
10	7	AI_ASSIST.md has all 3 sections AND ≥ 1800 chars AND no TODO lines (all-or-nothing)
10	8	README has ## Verification heading AND embeds an image from docs/ (all-or-nothing)
10	9	docs/execution_history.{png,jpg,jpeg} exists and is > 5000 bytes (PNG full, JPG half)

Test plan

• Scaffold (bare): 13/100, pass=false (Level 1 + Dockerfile base image only)
• Working solution at ~/Documents/github/hyf/data-assignment-week-6-test: 100/100, pass=true
• Grader runs cleanly (exit 0) in both cases
• Scoring ladder is monotonic: every Level the solution passes scores full points
• No scaffold comment / docstring accidentally pre-satisfies a grep check (verified by the 13-point ceiling)
• Code patterns verified: os.environ[...], from contextlib import closing, with closing(, logging.getLogger("azure").setLevel, ON CONFLICT, DO UPDATE, %s in multi-line execute(...), sslmode=require, BlobServiceClient

Build workflow followed: .agents/workflows/build_assignment_repo.md.

Pull request overview

Scaffolds the Week 6 “Deploy to Azure” assignment repository, including a starter pipeline module plus an autograder that performs static checks (no live Azure access) for expected implementation patterns and deliverables.

Changes:

• Added Week 6 starter files: src/pipeline.py stubs, Dockerfile, requirements.txt, .env.example, AI_ASSIST.md, and docs placeholder.
• Replaced placeholder README with Week 6-specific instructions and local-grading guidance.
• Implemented a points-based autograder in .hyf/test.sh with shared helpers in .hyf/grader_lib.sh.
