Create a branded LCV Ultrabrain reasoning session and optionally seed the first thought.

Canonical LCV reasoning gate for code work, branching, revisions, quality metrics, bias checks, confidence, and meta checkpoints. Protocol: state evidence and assumptions before conclusions; set step_type honestly (analysis, hypothesis, verification, conclusion...); attach evidence[] for any factual claim; branch when a materially different path exists and revise when an earlier step was wrong; adjust total_thoughts when scope changes instead of forcing a fit; only set next_thought_needed to false once a verification step has checked the conclusion. Close each step by asking: what am I missing or need to reconsider?

Update an existing thought with stronger evidence, confidence, risks, actions, or quality metrics.

Create or continue an Ultrabrain branch from a prior thought.

Merge one or more branch insights into a synthesis, best-evidence path, or decision note.

Check a reasoning session for evidence, alternatives, verification, bias, and closure gaps.

Analyze quality, confidence, bias counts, label counts, unresolved questions, and recommendations.

Render a reasoning session as a summary, linear chain, tree, markdown, or JSON.

Return session status, thought count, branches, and latest quality score.

Return recent normalized thought records for a session.

Export a session as markdown, text, or JSON.

Return aggregate session, thought, branch, quality, confidence, bias, mode, and step metrics.
