THE MEMORY ATLAS / INTERACTIVE ILLUSTRATIONOne document.
One document.
More than one place.
A deletion response is the beginning of the story. Follow the copies, then explore what a complete check needs to observe.
Baseline established. The document has more than one representation.
01 / THE EXPERIENCEFrom “deleted”
From “deleted”
to “here’s the evidence.”
A workflow that asks you to observe, not just assume.
Your workflow.
A more deliberate check.
Keep your local tools. Use the local dashboard for reference fixtures. The CLI and MCP also support configured staging runs, persistent evidence, and saved regression contracts.

Keep the boundaries.
Missing observations stay inconclusive. An unrelated control must survive. A pass covers the declared fixture contract.

Small defects. Different lifecycles.
Each one has a broken and a corrected reference implementation.
SQLite reference PATTERN 01 / INDEX CLEANUPThe source is gone.
The source is gone.
The vectors aren't.
A successful source deletion can leave derived records searchable. Check the index independently.
SQLite reference PATTERN 02 / BULK BOUNDARIESOne page deleted.
One page deleted.
More pages waiting.
The first 100 records disappear. The last 25 don't. Trace enumerates the complete fixture inventory.

Restored by a worker.
A worker reads an old snapshot and publishes after deletion. The fixture controls that exact interleaving.

Source and vectors are empty. Repeating the query can still return a cached synthetic canary.

NEW IN v0.3.2 / STAGING WORKFLOWOne contract.
One contract.
Every replay.
Run synthetic checks against an application you configure. Keep the assertions fixed as the implementation changes.
Connect a
staging target.
Register the application locally. Establish retrieval, inspect declared inventories, and preserve an unrelated synthetic control through the observation window.
Save the failure.
Keep the contract.
Persist evidence and an immutable regression definition. Checkpoints record synthetic IDs before writes, so interrupted runs leave a cleanup record.
Replay.
Compare the evidence.
Rerun the same lifecycle with fresh synthetic records. Compare compatible runs and their cleanup outcomes through CLI or MCP.
Validated locally with unmodified Mem0 2.2.1 and embedded Qdrant, using synthetic records. Active-memory deletion passed; audit history remained. This is a scoped local integration. Copies appearing after the observation window or in undisclosed stores can still be missed; this is not proof of complete erasure.

List registered external targets and inspect the plan for my-staging. Run its synthetic deletion contract and poll for final evidence and cleanup status. Save a confirmed failure. After I fix the staging app, replay the saved regression and compare without changing the assertions.
Eight tools cover reference fixtures; seven cover registered staging targets. Register endpoints locally first. MCP does not automatically inspect your repository or other tools.
04 THE BUILD RECEIPTS
RECORDED NOVEMBER 3, 2026A small release.
Verified locally.
The release suite checks both reference backends, external history and regression replay, and official-SDK MCP workflows. The release adds adversarial HTTP and interrupted-process checks. A separate seeded benchmark matched 170 expected labels, and ten Mem0 load lifecycles passed across 397 created records. These local results are not a production accuracy percentage.

A FEW IMPORTANT DETAILS
Good questions.
Clear boundaries.
Can I run it without funding?
Yes. The base engine, CLI, and dashboard use Python's standard library and run on your existing computer. No paid model API, GPU, cloud database, or subscription is required. Optional MCP and Qdrant support use downloadable open-source packages. Hardware, electricity, and internet access are still resources; an assistant client may have its own fees.
Will this scan my live application?
Version 0.3.0 can test a configured staging application through its documented HTTP adapter, using synthetic records. It requires explicit local setup and declared inventory coverage. The integration has been verified against a local Mem0-backed staging service. Its audit history is retained and outside the active-memory contract; customer and hosted deployments remain unvalidated. Production scanning is not supported.
Is Trace already a self-learning AI?
The current engine can prioritize tests using a transparent frequency-based heuristic from its local history. It does not train a model or demonstrate generalization. Adaptive generation and prioritization need evaluation against a strong fixed suite before we claim measurable learning.
What does a passing test establish?
It establishes that the selected reference or staging test met its stated API-visible deletion contract at the sampled observations, with an unrelated synthetic control preserved. It does not establish physical erasure, deletion from backups or model weights, legal compliance, or absence from unobserved systems.
Does the browser demo run the actual engine?
No. It is a labelled, simplified JavaScript simulation designed to explain the failure patterns. The downloadable Python engine executes real local source, vector, and cache operations and exports its own evidence.
