# Contribution record

This document records internally verified portfolio attribution while keeping the production repository private.

## Method

On September 8, 2026, GitHub's contributors endpoint reported:

- Keenan Francisco ([keenanfrancisco](https://github.com/keenanfrancisco)): 286 authored commits
- Caleb Ponce ([calebponce](https://github.com/calebponce)): 228 authored commits

The selected entries below were also checked against the private repository's local Git history for author, date, subject, and affected surfaces. Short commit identifiers are included as private-history references; they do not expose or link to the underlying source, and an outside reviewer cannot independently verify them.

Counts can change after the stated date. They represent attributed commits, not lines of code, relative importance, or sole ownership of collaborative product decisions.

## Keenan Francisco

Selected authored work:

| Private reference | Date | Public-safe summary |
| --- | --- | --- |
| d47ee80 | 2026-09-05 | Tightened the capture-to-return accuracy contract across backend, web, and iOS surfaces |
| c916f70 | 2026-09-06 | Prevented ground-truth measurements from being derived from a reference frame that did not share the required datum |
| 0b05bcb | 2026-09-04 | Added an independent replay baseline for adversarial evaluation |

## What this proves—and what it does not

This record supports the claim that both founders made sustained, substantive engineering contributions to Hardline. It does not claim that every listed decision belonged to one person, that commit count measures impact, or that this showcase reproduces the private work.

For interview diligence, either founder can provide a private architecture walkthrough or screen-share relevant history without distributing the repository.
