## What this file is

A downloadable record of the two-margin collision. It documents the six-step method, input boundary, labeled percents, and artifact inventory. The companion [aggregate CSV](https://infinisynapse.com/blog-media/data-knowledge-base/downloads/aggregate-KB-MARGIN-20260822.csv) contains only the published aggregate rows—not 14,000 raw rows.

## Verification materials

- [Verify the published aggregate CSV](https://infinisynapse.com/blog-media/data-knowledge-base/downloads/verify-KB-MARGIN-20260822.py)
- [External-source check](https://infinisynapse.com/blog-media/data-knowledge-base/downloads/external-source-check-KB-MARGIN-20260831.md)
- [Independent-reproduction protocol](https://infinisynapse.com/blog-media/data-knowledge-base/downloads/independent-reproduction-protocol-KB-MARGIN-20260831.md)

**Independent reproduction:** No qualifying unaffiliated report was known as of 2026-08-31. Running the verify script checks only the two published aggregate rows; it does not reproduce the private sanitized composite. **DOI:** none; this package is not registered with DataCite or another DOI agency.

## Six-step method (reproducible)

1. Pick one source you are authorized to read. Prefer a replica or sanitized extract.
2. Write or export a small pack: ten field notes and one approved report.
3. Upload the pack, then bind it to that source. Binding is a separate click from upload.
4. Ask one goal with the source selected—not a request for a SQL snippet.
5. Open the task artifacts and confirm the retrieved passages match the report you trust.
6. Ask the same goal again. If the bind held, the definition should not drift.

## Source and goal

| Field | Value |
|---|---|
| Source | Sanitized 14,000-row orders extract the desk is authorized to read |
| Source grain | One row per sanitized order record |
| Source version | Fixed desk extract dated 2026-08-22 |
| Collision | Sales `invoice − COGS` vs finance fees vs ops returns-after-fill |
| Pack metadata | First-party sanitized composite; owner: InfiniSynapse Data Team; hashes and source documents are not published |
| Bind mapping | Finance notes + signed report ↔ named orders extract |
| Retrieval configuration | Bound-pack retrieval; configuration values not published |
| Unbound baseline | Same goal and source with column names only |
| Goal asked twice | “What is last-month margin?” |

## Labeled percents

| Team definition | Formula in the notes | Unbound answer | Bound answer |
|---|---|---|---|
| Sales | invoice − COGS | 24.0% | 24.0% |
| Finance | invoice − COGS − marketplace fees | 24.0% (one number) | 18.5% |
| Ops | invoice − COGS − returns after fill | 24.0% (one number) | 21.0% |

The extract did not change. The notes changed what was allowed to count as “margin.” Wall-clock for the bound rerun was 22 minutes (warehouse time excluded).

## Task artifacts

| Retrieval state | SQL | Memo | Chart | CSV | Retrieved passages |
|---|---|---|---|---|---|
| Unbound (column names only) | 1 | 0 | 0 | 0 | 0 |
| Bound (finance pack + signed report) | 1 | 1 | 2 | 1 | 3 |

## Minimum disclosure for independent replication

Disclose source grain, row count, and version; pack and report hash, version, date, and owner; the three formulas; bind mapping; retrieval configuration; query, SQL, and passages; unbound baseline; all outputs and failures; run time; and conflicts of interest. Publish confirming and conflicting results.

## What you may cite

- Grain, collision, 24.0% / 18.5% / 21.0%, artifact counts 1 / 1 / 2 / 1, retrieved passages 0 → 3, run ID, ~22 min wall-clock

## What you may not claim

- Customer uplift, named-logo case, independent benchmark, certification, raw dataset, official EEAT score, or external validation
