Vithia
Verifiable long-horizon agents. Vithia turns long-running agent work into independently addressable evidence, bounded context, cryptographic breakpoints, and restartable successor state.
Golden route
Each boundary is explicit. Evidence, scoring, context selection, model-visible bytes, action, and observation are not collapsed into one opaque trace. Hashes establish identity and inclusion; they do not establish truth or causality.
Executed sponsor lanes
PASS + PARTIAL successor
1.2B tool-selection health passed. A fresh 2.6B bounded-classifier run was PARTIAL (0/6) and is preserved rather than promoted.
PASS
Live-source acquisition returned three source URLs; the successful receipt preserves the failed predecessor attempt.
PASS via RawTree backend
Fresh insert/query readback matched (HTTP 200/200). Direct Tinybird ingest remains NOT_TESTED/PARTIAL.
PASS
State visualization generated, downloaded, content-hashed, and linked into the governed evidence route.

Vithia model
Vithia is the sole model identity used for this submission. The public Hugging Face model card documents the FCO/FCG custody package, verification files, DOI anchors, and its explicit claim boundary.

What was observed
PASS
Golden-route breakpoint recomputation is recorded as passing through the sponsor successor.
PASS
The MVP supports reconstruction from committed object/graph state rather than replaying the original conversation.
PRESERVED
Failed sponsor attempts remain addressable predecessors instead of being overwritten by later successes.
EXPLICIT
Integrity receipts prove byte identity/inclusion, not scientific correctness or causal attribution.
