Problem statement

OpenSRE currently lacks a first-class Confluence integration. That leaves a gap for teams that keep runbooks, architecture notes, and operational procedures in Confluence and want the investigation agent to pull that context directly into RCA.

Proposed solution

Add a first-class Confluence integration that supports:

• onboarding, authentication, and connectivity verification
• searching and retrieving relevant runbooks and operational documentation
• pulling evidence from Confluence into investigation reports with clear citations
• using Confluence content during investigative planning and next-step generation

Acceptance criteria

• the integration is usable from the investigation workflow end to end
• setup and usage are documented clearly
• the implementation is backed by end-to-end tests in tests/e2e or equivalent
• the PR includes a screen video showing setup plus a successful investigation flow using Confluence
• vibecoding without testing will not be allowed; PRs without working end-to-end coverage and screen-video proof should be rejected
