Credential rule: Temporary AWS credentials belong only under the workspace secrets/ directory and are never copied into this wiki.

Challenge tasks

Status: Chain-of-thought-style operational prompt completed and exercised on 2026-09-09.
Method: Numbered parse, reservation-conflict, exact menu-membership, dietary/allergen, prioritization, resolution, and cross-check stages; output exposes only concise evidence and decisions rather than private reasoning.
Controls: Per-reservation validation matrix, exact menu-name set membership, exact allergen-set intersection, vegan-label validation, safe escalation, and fixed issue/action schema.
Model exercise: Nova Micro followed the required structure and detected the table conflict and vegan mismatch; the prompt was strengthened after the small model showed weak exact-membership reasoning. Titan Premier was authorized but invocation was denied by the lab role.
Submission prompt: /opt/data/channels/aws-jam-2026-challenge-10/challenges/task-010/submission-prompt.txt
Evidence: /opt/data/channels/aws-jam-2026-challenge-10/challenges/task-010/

Status: Prompt completed and tested on 2026-09-09.
Method: Two-example few-shot prompt with a fixed flight-confirmation schema and fail-safe handling for missing, conflicting, corrupted, and additional values.
Model test: Amazon Nova Micro in us-east-1 was AUTHORIZED; invocation succeeded.
Verification: The generated confirmation preserved every supplied passenger and flight detail, maintained the exact field order, and retained an extra meal preference under Additional details.
Submission prompt: /opt/data/channels/aws-jam-2026-challenge-10/challenges/task-009/submission-prompt.md
Evidence: /opt/data/channels/aws-jam-2026-challenge-10/challenges/task-009/

Status: Prompt completed and tested on 2026-09-09.
Method: COSTAR prompt with explicit Context, Objective, Style, Tone, Audience, and Response requirements.
Model test: Amazon Nova Micro in us-east-1 was AUTHORIZED and AVAILABLE; invocation succeeded.
Verification: Sample output included the customer name, dates, room type, total cost and currency, complete cancellation terms, and all hotel contact methods without inventing values.
Submission prompt: /opt/data/channels/aws-jam-2026-challenge-10/challenges/task-008/submission-prompt.md
Evidence: /opt/data/channels/aws-jam-2026-challenge-10/challenges/task-008/

Status: Completed and verified on 2026-09-09.
Translation: Amazon Translate converted the English data-center query to German (de).
RAG result: Nova Lite returned a German response describing three Tier IV data centers across the United States, Europe, and Asia, with 150,000 square feet of combined raised-floor space and resilient cooling, power, and networking.
Submission: The translated response was entered in the required widget; the unchanged Task 4 cell completed successfully; task4.json exists and contains a 256-value Titan embedding. No later code cells were executed.
Evidence: /opt/data/channels/aws-jam-2026-challenge-10/challenges/task-007/

Status: Completed and verified on 2026-09-09.
Knowledge Base sync: First ingestion job reached COMPLETE; 18 new documents were indexed and 2 documents failed processing.
Prompt: Requested an English summary of Octank Financial Corp.'s data-center locations, capacity, infrastructure, reliability, and operations.
RAG result: Returned a grounded English response describing three Tier IV data centers across the United States, Europe, and Asia with 150,000 square feet of combined raised-floor space and resilient cooling, power, and networking.
Submission: The unchanged Task 3 cell completed successfully; task3.json exists and contains a 256-value Titan embedding. No later code cells were executed.
Evidence: /opt/data/channels/aws-jam-2026-challenge-10/challenges/task-006/

Status: Completed and verified on 2026-09-09.
Knowledge Base: aws-KB-jam-317783770379, ID Z10DYJHIPA, discovered as the single active Knowledge Base in us-east-1.
Notebook: Rendered the Knowledge Base widget, set its value to the discovered ID, and executed through the unchanged submit_your_answer('task2.json', kb_id.value) cell.
Verification: Submission cell returned ok; generated task2.json contains the exact Knowledge Base ID; no code cells after Task 2 were executed.
Evidence: /opt/data/channels/aws-jam-2026-challenge-10/challenges/task-005/

Status: Completed and verified on 2026-09-09.
Region: us-east-1; SageMaker notebook instance SageMakerNotebookInstance-zCn04RrlkgD6.
Models: Amazon Nova Lite and Titan Text Embeddings V2 both reported AUTHORIZED and AVAILABLE; both notebook invocation tests passed.
Notebook: Executed code cells 6, 8, 10, 12, and 14, ending with submit_your_answer('task1.json', 'task1'); no later code cells were executed.
Submission: task1.json was listed in the notebook submission bucket with last-modified time 2026-09-09T10:47:28Z.
Evidence: /opt/data/channels/aws-jam-2026-challenge-10/challenges/task-004/

Status: Completed and verified on 2026-09-09.
Test: Uploaded a fresh JPEG object and matched its exact S3 key to the resulting DynamoDB ProductId.
Result: DynamoDB item count increased from 1 to 2; the new item category is Home Decor.
CloudWatch constraint: The lab session policy denies logs:FilterLogEvents; successful downstream DynamoDB creation proves the Lambda pipeline processed the upload.
Evidence: /opt/data/channels/aws-jam-2026-challenge-10/challenges/task-003/

Status: Completed and verified on 2026-09-09.
Function: product-categorization-function in eu-west-2.
Change: Timeout increased from 3 to the Lambda maximum of 900 seconds.
Verification: Function is Active; LastUpdateStatus is Successful; code hash and execution role are unchanged.
CloudWatch constraint: The lab session policy denies logs:FilterLogEvents; configuration was verified through the permitted Lambda API.
