# Systems Index

## Core Components

- [fid4.md](./fid4.md)
  Consumer app and the most important real-world validation environment.

- [xflowsdk.md](./xflowsdk.md)
  Backend-driven flow engine and the center of most Fidelity behavior analysis.

- [xflowviewmaker.md](./xflowviewmaker.md)
  Adapter layer historically involved in version bumps, release coupling, and removal evaluation.

- [ftframeworks.md](./ftframeworks.md)
  Consumer-side feature modules that often mediate whether XFlow changes can be validated in Fid4.

- [CogStore](./cogstore.md)
  Flow-configuration publishing and version-comparison platform used to verify what is live in QA/Production.

---

## Internal Apps And Tools

- [iosinstaller.md](./iosinstaller.md)
  Internal build-inspection app that can expose App Store/internal builds and their `Podfile.lock`.

- [artifactory.md](./artifactory.md)
  Artifact distribution surface used in release and build-validation workflows.

- [splunk.md](./splunk.md)
  Internal logging/observability tool for debugging distributed behavior.

- [discourse.md](./discourse.md)
  External issue/reporting surface that often feeds Fidelity triage and communication.

- [confluence.md](./confluence.md)
  Internal documentation/wiki surface.

- [jira.md](./jira.md)
  Primary work-tracking system for stories, sprint state, and planning.

- [miro.md](./miro.md)
  Shared whiteboarding/collaboration tool.

- [myaccess.md](./myaccess.md)
  Internal access/authentication-related tool.

- [trackit.md](./trackit.md)
  Internal tracking tool from the Fidelity toolset.

- [fidelity-central.md](./fidelity-central.md)
  Internal portal/entry-point app.

- [wukong.md](./wukong.md)
  Internal test-data-related tool.

- [xq1-portfolio-summary.md](./xq1-portfolio-summary.md)
  Internal XQ1 environment summary page/tool.

- [vault.md](./vault.md)
  Internal Fidelity tool named Vault.

- [vault-preprod.md](./vault-preprod.md)
  Pre-production variant of the internal Vault tool.

- [slate.md](./slate.md)
  Internal tool from the current Fidelity bookmark/tool set.

- [almx-toolbox.md](./almx-toolbox.md)
  Internal ALM/process-related tool.

- [nexus-fidelity.md](./nexus-fidelity.md)
  Internal Fidelity tool identified from the current bookmark/tool set.

- [launchdarkly.md](./launchdarkly.md)
  Feature-flag platform used broadly across the Fidelity workflow for rollout and environment-controlled behavior.

- [github-copilot.md](./github-copilot.md)
  Fidelity-side AI tool used broadly when richer product-side context is available on the development machine.

## Guidance

- Start with `xflowsdk.md` for backend-driven behavior questions.
- Start with `fid4.md` or `ftframeworks.md` for consumer validation and release flow questions.
- Open `xflowviewmaker.md` when the question involves version bumps, transitional architecture, or pipeline friction.
- Open `cogstore.md` when the question involves published flow-definition versions, config diffs, or whether a service/config change is live in QA vs Production.
- Open `iosinstaller.md`, `artifactory.md`, or the [Fidelity Apps Map](../../07-maps/fidelity-apps.md) when the question is about internal tools, build inspection, or where to look next.
