Build a Preferred Financing Backsolve and Identification Console
Investigate total equity values consistent with a financing price and specified investor rights. Separate primary financing evidence from secondary sales and unsupported valuation shortcuts.
What you are building
A preferred financing raises 50, but its rights differ from common stock. Build a calibration tool that shows which equity values fit the round under stated assumptions. The starter subtracts a hypothetical rights adjustment of 10 and divides by 40%, giving 100. Expose alternative fits. That shortcut is not a general preferred-stock pricing formula.
Rules
The linear fixture is a toy calibration, not an economically complete preferred-stock pricing formula. 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 bounded calibration service using the approved allocation engine. A financing evidence memo with a complete parameter and rights history. 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.

Learning goals
Determine which transaction terms are supported by evidence.
Calibrate a forward allocation model to the observed security price.
Test parameter bounds and alternative rights interpretations.
Export residuals and an identification limitations report.
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.
