Visible formula and sensitivity
Change an assumption. See the model move.
After the first complete result, changing a numeric input recalculates the model. Ranges and answer-changing assumptions stay visible in the artifact.
Forecast variance equals actual minus forecast, divided by forecast.
A dependency is fragile when channel share is at least 40%, recurring share is below 50%, absolute forecast variance is at least 20%, or attribution confidence is below 50%.
Estimated repeatable share sums each revenue share multiplied by its recurring share.
Definition and worked example
See the method before entering your own evidence.
Who should use it: Reconcile the growth narrative with the mechanics producing revenue.
Decision basis: The revenue dependency model compares concentration, recurring share, forecast variance, attribution confidence, retention, and the narrative claim. Forecast variance equals actual minus forecast, divided by forecast.

Where the free tool stops
The artifact makes the issue visible. The engagement resolves the organizational decision.
Petrichor helps the team reconcile disagreement, challenge evidence, assign ownership, and leave with a committed decision. You will not be asked to recreate this artifact.
This scored you once. The kit is the full rubric, built to paste straight into your LLM. Feed it to Claude or ChatGPT and score everything, on your own data. Includes the paste-ready file plus the designed PDF.

Questions about Revenue Story
What do I leave with?
A versioned revenue dependency model with visible reasoning, evidence status, next action, review date, and structured exports.
Does the result use a benchmark or AI?
No. The result uses the visible deterministic rules for this instrument and only the inputs you provide. It is not compared with other customers.
When does the paid work begin?
After the artifact. Petrichor helps the team challenge evidence, reconcile disagreement, assign ownership, and commit to the organizational decision without making you repeat the free work.
