Captain Landseed

Origin

Landseed's credibility depends on publishing verifiable claims, not marketing copy. The content arm needed to ingest peer-reviewed literature, extract claims with citations, and publish posts that any reader could trace back to primary sources. That pipeline needed to run autonomously — not as a scheduling tool, but as a system that internalizes the company's methodology, evidence standards, and voice and enforces them programmatically. An Embodied Company Agent.

Problem

Most corporate social media is assertion without citation. Most science communication strips the methodology to fit a character limit. The result is a public discourse where rigorous and casual claims are indistinguishable at the unit of a post. What's needed is infrastructure that carries its evidence chain — that will refuse to publish what it cannot verify.

Approach

A ten-stage pipeline: Fetch → Curate → Rank → Draft → Verify ↔ Revise → Review → Publish → Interact, with Outreach and Reflect stages running autonomously. Twenty-two data adapters ingest from arXiv, PubMed, Crossref, bioRxiv, RSS, and social platforms. A multi-persona council — sixteen cognitive stances including a fact-checker, compliance guard, and evidence rater — deliberates on each post before it reaches the publish gate.

Methodology

Citation-first by design. The evidence protocol requires every post to carry source references; banned phrases are enforced programmatically. Safety defaults are ON: approval mode, dry-run mode, and a hard publish-disable switch all default to preventing accidental posting. Maximum three posts per day, weekdays only. The system can run unattended but will not publish without clearing its own evidence threshold.

Selected milestones

• Ten-stage pipeline operational end-to-end
• Twenty-two data adapters ingesting across academic, news, social, and environmental sources
• Sixteen-persona deliberation council with voting and operator approval
• Mission Control dashboard with real-time SSE streaming and command palette
• Deployed on Fly.io as captain-planet
