What problem does it solve? Evidence queries in Fianu are keyed on a series (digest, commit, tag, release, time period), and querying the wrong series returns empty results even when evidence exists. This Skill teaches how to target the correct series so attestations, violations, and findings are actually found. ## Core Features & Use Cases - Series Model Reference: Covers the full series catalog (digest/uri/commit/tag/release/timestamp/period_*), and disambiguates seriesName vs seriesCode vs seriesId vs seriesType. - Four Query Modes: Single-series snapshot and violations endpoints, cross-series association queries, series discovery via by-series, and the commit-scoped export endpoint returning full raw notes. - Use Case: A user asks why Artifact Signature or SBOM controls return empty for a commit. The Skill explains these controls land on the digest series, and directs using the by-series discovery endpoint or the export endpoint to locate the digest-keyed evidence. ## Quick Start Ask the agent to list all control results for an asset at a specific git commit, including failing violation details, using the Fianu attestations export endpoint.
