Build a Point-in-Time Economic Release Terminal
Reconstruct the economic information available at a chosen decision time. Let analysts compare original releases, later revisions, and the conclusions each version supports.
What you are building
What could an analyst actually see at noon on February 1? Build a release browser that reconstructs the record at a chosen instant, then shows what changed later. Include an observation released at 11:59:59 UTC and exclude one released after noon. The starter tests the clock rule. A current snapshot alone cannot supply the historical releases.
Rules
Do not claim that currently available observations were known historically. 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.
Versioned observation store and as-of query API. A note that separates release surprise from historical revision. 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
Store immutable release snapshots with hashes.
Apply the decision-time filter before selecting observations.
Recompute changes using only eligible vintages.
Export a dated note with cell-level evidence links.
Resources
3 attached datasets, including two visible synthetic starter cases. MAC-01 and MAC-03 prototype release records. Not real employment data. The fixture ZIP supplies synthetic exercise inputs. It does not supply independently verified real-world records.
