Capstone 02 · Maple Pantry

Carry the method somewhere new.

The setting changes. The questions and reasoning travel with you.

Our question

How many people participated, in which roles, during September 14–20?

Fictional teaching records. Start with a purpose; the starter sketch includes assumptions for you to inspect.

03 / Evidence & revision

A source tells us where a claim came from. Validation tells us how far we have checked it.

Noor’s question

Participant accountsupported

For September 14–20, how many people volunteered, how many people collected food, how many households received it, and how many distributions did we make?

Fictional reporting definitions for this exercise; not universal pantry rules. Noor is outside the counted population.

The first records

Supplied recordsupported

Ana and Ben volunteered in V1–V3. Distributions D1–D4 reached H1, H2, and H3. The summary does not show who collected them.

Two volunteers, three volunteer participations, three households, four distributions. Recipient people and unique people remain unknown.

Your model’s working assumption

These links can represent the people and roles needed by the report.

Working assumptionunchecked

If your model already fits the new fact, explicitly validate this assumption with the new evidence.

04 / Inspect the revision

What changed, and why?

No evidence-linked revision yet. Read the new fact, inspect your model, and make or validate a change.

Undo restores the model and its evidence state together.

These are evidence counts. Check whether your chosen model can explain them.

What does this report count?

A volunteer is a person with at least one recorded volunteer participation during September 14–20.
Recipient people means the distinct people recorded collecting food. It does not count every household member who may eat it.
A household is counted once if it received at least one distribution in the period.
A distribution is one completed food handoff to one household. A repeat visit is another distribution.
Unique participants means distinct people who volunteered or collected food. Combine their identities once; do not add role totals.

Leaving someone out of a role they performed understates activity; inventing a role unsupported by records overstates it. The model must support accurate records and explainable counts.
