# Technical documentation — footprint-lambda

Evidence date: 2026-10-14. Source: `git@bitbucket.org:overdrive/footprint-lambda.git`, `master` at `351a5ca129d32c1a91550dbd2b7f3be8b7656b25`.

Provenance labels: **Documented**, **Implemented**, **Inferred**, **Planned**, **Unknown**.

No technical document existed in the repository or in `silicon_ark/footprint-lambda/` before this file.

## What this repository is

A Bitbucket Git repository in the `overdrive` workspace with slug `footprint-lambda`. On 2026-10-14 `master` contained one commit and one file.

Provenance: **Implemented** (clone, `git log`, `git ls-tree`, `git ls-remote`).

It is not the application documented under `silicon_ark/FootPrintLive/`, the match centre under `silicon_ark/matchcentre.footprintapp.net/`, the stub under `silicon_ark/tournaments.footprintapp.net/`, or the heading-only repository under `silicon_ark/Footprint-Not-Used/`. Those are separate repositories. This tree does not name them.

## Inspection method

1. `git clone --depth 50 git@bitbucket.org:overdrive/footprint-lambda.git` on 2026-10-14. History is a single commit, so the shallow clone is the full history. `git rev-list --all --count` printed `1`.
2. `git ls-remote --heads --tags origin` printed `351a5ca129d32c1a91550dbd2b7f3be8b7656b25` for `refs/heads/master` only.
3. `git branch -a` listed `master`, `origin/master`, and `origin/HEAD -> origin/master`.
4. `git tag -l` printed nothing.
5. `git ls-tree -r HEAD` listed `.gitignore` only. `git rev-parse HEAD:.gitignore` is blob `b24d71e22373e5147f3c05c68a8742714a89b5d6`. `git cat-file -s` reports 624 bytes. The raw blob has 50 LF bytes and 0 CR bytes, and starts with `# These are some examples`.
6. The scan-host path `~/projects/sonar_scan/repos/footprint-lambda` does not exist on this machine (`%USERPROFILE%\projects\sonar_scan\repos\footprint-lambda` is absent). The two Sonar filenames in OVER-126 were therefore not opened.
7. Bitbucket repository metadata through the Bitbucket API client returned HTTP 401, so project settings, default-branch configuration beyond `origin/HEAD`, and permissions were not read. Git's `origin/HEAD` still points at `origin/master`.

A Windows working copy of `.gitignore` was 674 bytes with CRLF (50 CR + 50 LF). That is the checkout conversion of the 624-byte LF blob (624 + 50 = 674). The committed object is the LF blob.

## Application structure

```text
footprint-lambda/
└── .gitignore
```

No `app/`, `src/`, `public/`, tests, pipeline, `serverless.yml`, or infra directory exists in the remote. Local `.git/` after the clone is client metadata and is not a project source file.

## The only file

`.gitignore` at `351a5ca`, blob `b24d71e22373e5147f3c05c68a8742714a89b5d6`, 624 bytes, 50 lines, LF in git.

The header says:

- "These are some examples of commonly ignored file patterns."
- "You should customize this list as applicable to your project."
- A link to `https://www.atlassian.com/git/tutorials/saving-changes/gitignore`.

Patterns that follow, grouped as the file comments group them:

| Comment in the file | Patterns |
|---|---|
| Node artifact files | `node_modules/`, `dist/` |
| Compiled Java class files | `*.class` |
| Compiled Python bytecode | `*.py[cod]` |
| Log files | `*.log` |
| Package files | `*.jar` |
| Maven | `target/`, `dist/` (second time) |
| JetBrains IDE | `.idea/` |
| Unit test reports | `TEST*.xml` |
| Generated by MacOS | `.DS_Store` |
| Generated by Windows | `Thumbs.db` |
| Applications | `*.app`, `*.exe`, `*.war` |
| Large media files | `*.mp4`, `*.tiff`, `*.avi`, `*.flv`, `*.mov`, `*.wmv` |

Provenance: **Implemented** (file contents at `351a5ca`).

**Inferred:** this is a host-generated starter ignore file. The commit message is `Initial commit`, the commit contains nothing else, and the header tells the reader to customize the examples. That file does not select a language. Node, Java, Python, and Maven patterns appear together because the template lists them together.

`sonar-project.properties` and `sonarqube_scan.bat` are not among the patterns. If those files were present and untracked, this ignore list would not hide them.

The blob hash is the same hash recorded for `IOSApp` (`ee54dfb`), `smart_overdrive` (`1b27efb`), `intersect_cloud_v2` (`6dd7641`), and `im_flutter_app` in their Silicon Ark technical documents. Same Git blob hash means the file bytes are identical. That is a template comparison only. Those pages record other remotes and other dates. This repository does not name them. The other blobs were not re-hashed in this session; the comparison is against the hashes those documents already publish, which match the hash computed here.

## Frameworks and languages

None are implemented. There is no source file and no dependency manifest.

| Signal | What it is | Provenance |
|---|---|---|
| Node, Java, Python, Maven, media, and binary patterns in `.gitignore` | Example ignore groups in one starter file | **Documented** as comments and patterns. A selected stack is **Unknown** |
| Slug `footprint-lambda` | Repository name | **Implemented** as the remote URL. An AWS Lambda runtime is **Unknown** |
| `serverless.yml`, `package.json`, `composer.json`, `*.py`, `*.java`, `*.js` | Would identify a stack. None are in git | **Unknown** whether any stack was intended |

## Runtime configuration

None. There is no `.env`, config file, or settings class. `.env` is not an ignore pattern in this file.

## Authentication

None in the tree. No login route, token, session, or secret store.

Git commit identity is `Jaco Brits <jaco@overdrive.co.za>`. That is author metadata on `351a5ca`, not an authentication mechanism.

Bitbucket access control for push and admin was not listed (API client returned 401). **Unknown / Requires Confirmation.**

## Data

No database, schema, migration, or seed. No product records are stored in git.

## APIs

No HTTP route, client, OpenAPI file, or Lambda event mapping.

## Background work

No worker, queue, cron, or pipeline definition. There is no `bitbucket-pipelines.yml`.

## Storage

No bucket, disk path, or upload handler.

## Build, environments, and scripts

No build script. No `Dockerfile`, `docker-compose`, `Makefile`, `template.yaml`, or host-specific config.

## Testing

No test runner and no tests. `TEST*.xml` is an ignore pattern in the starter file. No such report is in git. There is nothing to execute.

## Security notes (observed, not a pentest)

No application surface is present, so there is no route or dependency to review. No credential file was in the tree. The ignore list does not contain a secret.

## Deployment and operations

**Unknown / Requires Confirmation.** Nothing in git names a host, a region, a pipeline, a document root, or a monitoring system.

OVER-126 lists `sonar-project.properties` and `sonarqube_scan.bat` on the scan-host working tree. They are not in the remote, and their contents were not read. A Sonar project key, server URL, or scan command cannot be stated.

## Human confirmation

- Intended language, framework, and host, if this repository is still a planned codebase.
- Whether "lambda" was meant to mean AWS Lambda.
- Bitbucket project permissions.
- Contents of the scan-host Sonar files, if they are considered part of the project.
- Whether any other Footprint or Lambda repository was meant to replace this one.
