Build a Chain-Linked GDP Growth Contribution Explorer
Explain real GDP growth using published contribution measures. Prevent analysts from treating chained-dollar component levels as an additive accounting identity.
What you are building
Published contributions of 1.2, 0.5, and 0.4 percentage points explain 2.1 points of growth. Build a contribution chart that reconciles the published figures and flags incompatible release dates. Block a chart that mixes vintages. Adding chained-dollar component levels is not a substitute for using compatible contribution measures.
Rules
The fixture checks arithmetic reconciliation only, not the complete chain-index calculation. No fabricated records, source citations, professional endorsements, or expert-adjudication claims. No future-data leakage into dated decisions, model fitting, or historical valuation inputs. No unauthorized payments, account restrictions, regulatory filings, or production changes. No automated appraisal certification, tax-compliance determination, or unsupported fraud accusation. No concealed uncertainty or silently invented inputs required for a numerical conclusion.
How work is evaluated
100-point weighted review with safety gates. Visible starter cases do not establish full application correctness.
A release-linked decomposition dataset. A chart export that identifies contribution units and rounding differences. Runnable local application, setup commands, and a dependency lockfile. Versioned input data, data dictionary, acquisition instructions, and rights notes. Calculation traces, source references, assumption records, and exported review artifacts. A deterministic baseline and tests for normal, incomplete, contradictory, and failure-recovery cases. A recorded complete workflow with a reproducible manifest and explicit limitations.
Datasets
Public datasets, plus the private datasets you have access to.
How submissions are scored
Learning goals
Align release versions and component definitions.
Build contribution waterfalls from published contribution tables.
Calculate and disclose rounding residuals.
Export an explanatory chart with rejected invalid aggregations.
Resources
2 attached datasets, including two visible synthetic starter cases. The fixture ZIP supplies synthetic exercise inputs. It does not supply independently verified real-world records.
