Knowledge that can be traced, attested,
and replayed.
SHIVA is a provenance-first, graph-native, policy-executable system for clinical and scientific work. It turns raw information into claims that survive audit — and tools that can be rerun a year later with the same hash, the same figure, the same conclusion.
The SVF Clinical Platform
ships as a paid product.
A separate, licensed bundle for clinical partners delivering stromal vascular fraction cell therapy. Seven capsules — patient selection, clinical pathways, OSCE stations, business & regulatory framing, and a working developer engine. Two are free to read in the browser right now; the full clinical bundle ships as a single download under a single-clinic license.
Most systems store information.
A few can reason over it.
SHIVA can be audited.
“No high-stakes action without ontology, provenance, attestation, policy, and auditability.”
What does it mean?
Every claim is bound to an ontology version. No silent vocabulary drift, no ambiguous terms passed between humans and machines.
Where did it come from?
Event-sourced lineage from raw artifact to deployed conclusion. Every transformation appended, never overwritten.
Can we replay it?
ProofPacks bundle the data, code, prompts, and environment needed to regenerate any output — bit-identical, hash-matched.
Each tool ships as a self-contained capsule — one HTML file, no dependencies, runs offline.
Spine planning, manuscript sealing, dataset audit, knowledge mapping — each capsule embeds its own code, schemas, tests, and integrity manifest. Open in a browser. Works on an airplane.
SPIN-THA
Open, deterministic, browser-based spinopelvic THA planning support. Rotation-matrix cup orientation, Monte Carlo, FHIR R4 + DICOM SR (TID 1500), Ed25519-signed manifest. Surgeon-supervised — not a diagnostic device.
SHIVA Spine Toolkit
Trust the math. Ship in 90 s. Agree within ±2°. 8-phase roadmap targeting Surgimap-grade quality.
SHIVA TraceProof
Deterministic execution + attested agents + Codex workspace. 100% receipt coverage or the run is rejected.
SHIVA ArticleMap
Deterministic scientific release bundling. ship · verify · capsule. Python CLI + self-contained HTML capsule.
SHIVA Supply Chain
11-stage deterministic release pipeline. DSSE Ed25519, MerkleCommit, deterministic ZIP, SQLite audit, in-toto/Cosign/Rekor/PAR2/OTS adapters.
Validation Bundle
Clinical data sanity + meta-analysis verifier + verifiable eval suite + Valida Pro workbench.
Sagittal Load Corridor
Per-patient mechanical envelope. ΔLL → ΔSVA from geometry, not regression. PI–LL band, SVA target, ΔSLL breakdown.
SHIVA AS
Spinopelvic toolkit specialized for ankylosing spondylitis. AS-specific landmarks, compensation collapse, osteotomy framing.
Energy-Aware Alignment
Alignment as energy minimization. Capsule + manuscript core + SAP + risk register + codebook + synthetic validation set.
SHIVA DomainWorks
Convert difficulty into simplicity. 9-agent mesh, 8 product categories. The multi-domain productization engine.
SHIVA Spine Biomech
Verified open-resource registry + clinical-FE longitudinal release framework + synthetic SQLite cohort. Open longitudinal dataset scaffolded.
That's the 11 canonical projects (per the SHIVA Portfolio Control Panel).

Twelve engines.
One audit trail.
SHIVA OS is built around a set of cooperating engines — each with explicit responsibilities, hard invariants, and replayable outputs. Nothing here is a black box.
Identity
DID binding, role scopes, attestor eligibility. No anonymous execution.
Ontology
Schema, vocabulary, claim types. No executable claim without binding.
Ingestion
Artifacts → typed candidate claims. Raw source remains immutable.
Provenance
Event-sourced lineage DAG. Every mutation appended, never overwritten.
Evidence Vault
Content-addressed, encrypted, optionally anchored. Tombstone with proof.
Graph Core
Semantic graph with conflict edges. Contradictions coexist, with status.
Attestation
Signed witness events. Multi-party for high-stakes claims. Revocable.
Policy
Rule execution, jurisdiction overlays. No execution without verdict.
Execution
Authorized knowledge → action. Every action references its claims.
Governance
Proposals, voting, disputes. Constitutional invariants are protected.
Reflection
SHIVA inspects and repairs itself. Recursion bounded by policy.
Checkpoint
Merkleized digests, anchored roots. Replayable system state.
Built on a few rules
that don't bend.
SHIVA is opinionated by construction. These aren't aspirations — they're invariants enforced by the engines themselves.
Everything is clickable.
Every kernel ID links to its kernel page. Every claim links to its evidence. No floating assertions.
Every claim has a context.
No context → the report labels it context missing, and it cannot be used for recommendations.
Uncertainty is first-class.
Every recommendation carries an evidence grade and explicit fork conditions. No false confidence.
Contradictions are shown, not hidden.
Conflicting claims surface as folds — explicit unresolved tension, not silently overwritten.
Sheets have identity.
Every artifact displays lineage_id, sheet_hash, version, and diffs from previous versions.
Replay or it didn't happen.
If a result can't be regenerated bit-for-bit from the ProofPack, it's not a result yet.

Collaboration, licensing, clinical pilots, press, grants — all welcome. The contact page has lanes that help me triage, but the fastest path is email. I read everything.
