# Engineering infographic manifest

These 1600 × 900 PNGs are historical deterministic documentation artwork. They use the retired NYTSHIFT compass without changing its geometry, colour, crop or aspect ratio. The compass is no longer an active product mark.

## Production record

The source SVGs are retained in the adjacent NYTSHIFT launch-kit source bundle under `gitbook/artwork-v2/`. They are not duplicated in this repository.

## Embedded product-capture provenance

The approval and paper infographics embed two time-specific product captures from the launch-kit `assets/captures-v2/` evidence bundle:

| Embedded capture             | SHA-256                                                            | Source evidence                                                          |
| ---------------------------- | ------------------------------------------------------------------ | ------------------------------------------------------------------------ |
| `terminal-approval-live.png` | `9b0c880ec1f86cb1d6153f6b8f3c3b6cc9c6dd142b05f6c706285a0be79b7528` | Production origin `https://nytshift.xyz`; terminal approval state        |
| `terminal-paper-live.png`    | `79ec24d60869406a02ecf762835bb937a7a2ee1be2badfb855359f986ecba5a2` | Production origin `https://nytshift.xyz`; terminal live-book PAPER state |

The source report was captured at `2026-07-15T05:20:44.949Z` with a `1600 × 900` viewport and has SHA-256 `dfdc8b1ace0f23f045a7e6675a048515b644406014c598bd4731bd9d95aefbd0`. That report records no issue notes, but it does not retain the exact deployed commit, final route URL, console count, horizontal-overflow result or zero-mutation audit. Those fields therefore remain **unknown** and this artwork must not be used as release, runtime-readiness or execution evidence.

## Validation

Each source SVG passed `brand_guard.py validate-svg`; each rendered PNG passed `brand_guard.py validate-png` and was inspected at its original resolution. The retired compass SHA-256 used by every historical frame is:

`ab961b34fb6e0e89a5e21030b67e3c6834b6c1330054926d1105ecb1bccd1d51`

The approved product mark that superseded it on 2026-07-29 is `nytshift-symbol-dark-master.svg`, SHA-256 `99639263b15ab38d6fc48fbc1d6e13cfda0765551c4b9bffa65622c3e85255fb`. The retired compass product files are retained under `docs/assets/brand/legacy/` for provenance only and must not return to active UI.

The terminal captures are historical presentation evidence, not a promise that the displayed price remains current. Execution remains locked unless the independent signer, eligibility, policy and user-authority gates all pass.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://nytshift.gitbook.io/nytshift-docs/evidence-and-handoff-records/infographics.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
