Your Mac's filesystem,
with clearance.
Turn selected folders into a private, encrypted semantic index. Search by meaning, answer from cleared results, and keep a hash-chained local log of file activity when compliance matters.
Search is not enough when the record matters.
Spotlight tells you a file exists. Metatron Enclave tells you which file you meant, by meaning, and only ever shows results the caller is cleared to see.
In healthcare, legal, medical dispatch, finance, and other regulated fields, teams also need a record. If a client, auditor, or regulator asks what was read, written, or used to justify a decision, the organization needs a log of file activity to point to.
You need private semantic memory, clearance enforcement, and a hash-chained log of file activity.
Three layers of filesystem intelligence.
The index moves at syscall speed.
The Endpoint Security extension watches file change events in selected folders. Each relevant delta is deduplicated by content hash, embedded locally or through your configured provider, classified by sensitivity, and merged into an encrypted .meb vector store.
Answers only from what you can see.
Every vector carries a clearance level from path and content classification. Local Q&A cites only cleared results.
A hash-chained log of file history.
Enclave watches file activity through Apple's Endpoint Security notify events. Enterprise Mode snapshots changed files into a compressed archive and appends hash-chained metadata to a local compliance-ledger.jsonl, with a signed export for auditors.
A file changes. Enclave remembers.
Delta captured.
The privileged system extension detects a meaningful file event, filters by watched folders, extension, and size, then sends the change to the host app over XPC.
Meaning classified.
The file is embedded, deduplicated, classified by path and content, and written into the encrypted local store. Secrets, PII, legal, finance, and customer material round up to the more restrictive clearance.
Activity logged.
In Enterprise Mode the same delta is compressed with Apple's native Compression framework, stored by SHA-256 content hash, and linked to the prior ledger entry by SHA-256 hash.
Two modes. One serious upgrade path.
Developer Mode is the free standard tier: selective folder indexing, local Q&A, transparency, and encrypted storage. Enterprise Mode adds the hash-chained activity log, file archiving, signed auditor export, and central sync.
