Marivo 0.4.15

Marivo 0.4.15 makes analysis and datasource contracts more actionable, renders typed findings as bounded bilingual evidence, and hardens bounded probes and time-window execution.

Highlights

Section titled “Highlights”
  • Focused marivo.help("analysis.<target>") now exposes exact parameter construction routes for non-family values, including closed policy vocabularies and retained PatternStep values from a journey artifact. Agents can continue from Prerequisites and Parameter construction without reconstructing typed inputs.
  • Finding.render() and FindingPage.render() now produce bounded, one-line evidence statements in English or Chinese. Page rendering retains canonical finding_id values, and delta statements can show exact half-open comparison windows for follow-up reads.
  • md.connect() and md.test() now enforce a Marivo-side connection/round-trip deadline (30 seconds by default, configurable with keyword-only timeout_seconds). Timeout results distinguish the connection handshake from the SELECT 1 round-trip and provide structured repair guidance.
  • md.raw_sql() now injects its probe limit into the same top-level SELECT or set operation, preserving user ORDER BY ... LIMIT Top-N semantics while retaining truncation detection.

Changed

Section titled “Changed”
  • Analysis capability registries now describe exact construction and selection routes and closed value contracts for shape, anomaly strategy, ranking, normalization, and normalization baselines; dynamic artifact contracts retain derivable values for recovery.
  • Evidence delta payloads retain exact comparison windows, and finding rendering covers typed variants without querying Session state or fabricating labels.
  • Datasource failures expose timeout configuration and phase-specific codes; thread-affine SQLite connections remain on the caller thread while network backends fail closed on deadline.

Fixed

Section titled “Fixed”
  • Hour-precision partition scans now treat end bounds as half-open at the exact hour, avoiding inclusion of the end bucket and preventing pairing shortfalls.
  • Trino native percentile attribution reuses equivalent percentile fields and coalition predicates within a batch, preventing regex-derived expression traversal recursion while preserving results.

Documentation

Section titled “Documentation”
  • Updated the analysis workflow, evidence, semantic-layer, and API documentation, and documented the progressive semantic authoring help design.
