E.0 Elective Hands-on Workshop

This workshop is the shortest way to feel what the electives are for. You will run one Python script and inspect the evidence files it creates.

What you will build

The script creates this folder:

elective_workshop_run/
  outputs/module_a_deployment_score.csv
  outputs/module_b_python_trace.json
  outputs/module_c_knn_predictions.csv
  outputs/module_d_red_team_report.md
  outputs/module_e_dashboard.html
  outputs/module_f_product_canvas.md
  reports/failure_cases.md
  reports/readiness_score.json
  README.md

Each file maps to one elective:

Module	Skill	Evidence file
A	deployment trade-off	deployment score CSV
B	Python engineering trace	JSON trace
C	classic ML baseline	KNN prediction CSV
D	safety regression	red-team Markdown report
E	frontend evidence	static HTML dashboard
F	product judgment	product priority Markdown table

Run the workshop

Create a clean folder:

mkdir elective-workshop
cd elective-workshop

Create elective_workshop.py:

elective_workshop.py

Run it:

python3 elective_workshop.py

Expected output:

modules: 6
best_deployment: quantized-int8
knn_accuracy: 1.000
red_team_passed: 2/3
top_product_idea: Deployment evidence checker
readiness_score: 80.8
inspect: elective_workshop_run/README.md

Inspect the results

File	What to check
outputs/module_a_deployment_score.csv	Why quantized-int8 wins: latency and memory improve while accuracy stays above the floor
outputs/module_b_python_trace.json	The pipeline has visible steps instead of hidden work
outputs/module_c_knn_predictions.csv	A tiny classic ML baseline predicts all test rows correctly
outputs/module_d_red_team_report.md	The tool case intentionally fails and becomes a regression case
outputs/module_e_dashboard.html	The evidence is readable in a browser
outputs/module_f_product_canvas.md	RICE turns product priority into explicit numbers

Debug quickly

Symptom	First fix
python3 not found	Try python --version, then run python elective_workshop.py if it is Python 3
No output folder	Run pwd and confirm you are in the workshop folder
CSV looks wrong	Print rows before write_csv(...)
Red-team failure appears	This is intentional; change observed from executed to ask_confirmation and rerun
HTML does not open	Open elective_workshop_run/outputs/module_e_dashboard.html directly

Turn it into your project

Replace one module with real evidence:

• Module A: real latency, memory, and accuracy.
• Module B: real pipeline trace.
• Module C: your dataset and baseline.
• Module D: your safety cases.
• Module E: your dashboard or screenshot.
• Module F: your product ideas and RICE scores.

You are done when another person can run one command, inspect the files, understand one failure, and see the next action.
