Landing claims ledger (every sentence on the public surface, traced to the code a customer can actually use)
Read-only. Classifies every claim on an org's public surface (copy, captions, tables, alt text, metadata, share card) and traces it to the mechanism at a named commit, with a verdict and a customer-usable-today test. Field-derived from traceo.cat (2026-10-21), where code existed for most false claims.

notes
Field-derived. traceo.cat, 2026-10-21, read at traceo-mcp-server d93efce.
CODE EXISTING IS NOT A FEATURE. Every false capability claim had code behind it: MCP tools (no customer token to
connect), baseline diff (tenant allowlist under decision 0104), a diff screen (browser fixture, route hidden),
RBAC (decorators no-op while ENABLE_RBAC is unset), Team "unlimited seats" (no invite path). Ask "can a self-serve
signup use this today", not "is there code for this".
DOCS ARE CLAIMS, NOT EVIDENCE. A first pass took features from the org's strategy docs (YAML↔git sync, audit-log
export, per-tool MCP permissions) and recommended promoting them. None was implemented for customers. Verify every
feature against source, including ones you "know" from documentation.
QUANTITIES NEED A RUN. "1,000 rows" traced to a 60-row capture fixture and a 1,000-row mocked smoke test, never a
workspace. "Every state colour is checked against WCAG AA" traced to a CI script checking its own hard-coded copy of
the palette, with the brand colour in no required pair (the CTA failed at 3.93:1).
TRANSCRIPTS ARE CLAIMS. A code sample showed traceo.requirements.search { baseline: "v3.2" }; the real tool is
search_requirements with no baseline parameter, returning a JSON envelope, not a table.
description
Use when checking whether a landing page, pricing page or docs index says only what the product does: "build the claims ledger for traceo.cat", "which landing claims are false", "does the site oversell". Read-only. Every sentence becomes a row with a claim class, a file:line mechanism, a TRUE / PARTLY TRUE / FALSE / NOT ESTABLISHED verdict, the true wording where one exists, and whether a self-serve customer can use it today. NOT for rewriting the copy (landing-truth-sweep) and NOT for funnel or layout checks (landing-funnel-integrity-audit).
