When a multi-strategy hedge fund or a sovereign-adjacent allocator sends proprietary OHLCV data to an external research vendor, the legal and compliance footprint is non-trivial. Data-use attestations, lifecycle certificates, and demonstrable zero-retention architecture are the table-stakes that retail backtesting platforms have never had to meet. Student One was built around these requirements from day one.

## What "Ephemeral Compute" Actually Means

      Most "cloud backtesting" services run on shared infrastructure where your data lands in a persistent database, sits in cache layers, transits CDN edge nodes, and is logged for telemetry. Even when the vendor claims privacy, your data has touched many surfaces and exists in many places — backup snapshots, replication targets, audit logs, debug dumps.

      Ephemeral compute means none of that happens. The pipeline is:

- Client uploads data to a per-job isolated S3 bucket via signed URL

- A fresh compute instance is provisioned (RAM-only for enterprise tier; no instance store, no EBS persistence)

- The instance pulls the data into RAM, runs the statistical engine, writes only the result bundle

- The instance is destroyed; the S3 ingress bucket is purged; the egress bundle is delivered to the client; the egress bucket is purged after delivery confirmation

- A cryptographic lifecycle certificate is signed, documenting every state transition with timestamps and hashes

## The Lifecycle Certificate

      Every job produces a signed JSON manifest containing:

- SHA-256 hash of the input data (computed at ingress, before any processing)

- Instance ID and provisioning timestamp

- Engine version, gate configuration, and seed values

- SHA-256 hashes of every output artifact

- Destruction timestamp for input data, intermediate state, and compute instance

- Cryptographic signature from a hardware-backed key

      This certificate is the audit trail. A compliance officer can independently verify: input data existed only between timestamp X and timestamp Y; no human accessed the instance; no data was replicated; output hashes match what was delivered.

## 72-Hour Maximum Retention (Dojo Tier)

      The free Dojo tier uses ephemeral compute with a hard 72-hour retention ceiling for result bundles — after which they are purged from the egress bucket regardless of whether the user downloaded them. This is enforced at the storage policy level, not by application code. Users who need longer retention export the bundle within the window.

## RAM-Only Enterprise Compute

      The ESER™ and SlipStream™ enterprise tiers run on instances with no persistent storage at all — no instance store, no EBS volume, no swap. Data exists in RAM during the job and nowhere else. When the instance terminates, the data is gone in the most physical sense possible: the RAM is wiped during instance teardown and the underlying hypervisor reclaims the memory pages.

## Why This Matters for Regulated Allocators

      SEC-registered investment advisers, FCA-regulated firms, MAS-licensed asset managers, and SEBI-registered entities all face data-handling rules that prohibit sharing client-derived strategy data with third parties who cannot demonstrate destruction. A lifecycle certificate that cryptographically attests to destruction is the difference between "we used an external vendor" being a compliance footnote versus a multi-month remediation project.

      The same applies to family offices managing UHNW capital, sovereign wealth funds with statutory data-locality requirements, and banks subject to operational risk frameworks (Basel III, equivalent regional regimes).

## What Ephemeral Compute Does Not Mean

      It does not mean "we promise not to look at your data." It does not mean "we encrypt at rest and at transit." Those are baseline security hygiene that every credible vendor provides. Ephemeral compute means the data physically does not persist beyond the compute window — there is no "at rest" because there is no rest. There is only execute-and-destroy.

## Comparison to Conventional Cloud Backtesting

| Property | Conventional Cloud Backtesting | Student One Ephemeral Compute |
| --- | --- | --- |
| Data persistence | Database + cache + logs | RAM only (enterprise) / 72h cap (Dojo) |
| Lifecycle certificate | No | Yes — cryptographically signed |
| Instance reuse | Shared / pooled | Per-job isolated, destroyed after |
| Backup snapshots | Routine | None |
| Compliance posture | Vendor attestation only | Independently verifiable hashes |

## Summary

      For institutional research, "we won't share your data" is not a security model — it is a press release. Ephemeral compute with cryptographic lifecycle certificates is a security model: it converts vendor trust into auditable computation. That is why Student One built the engine this way from the first commit, and why enterprise allocators can engage without month-long legal reviews.
