# Known limitations

These are current product boundaries, not footnotes.

## Context conflicts are incomplete

`include: ["memories"]` materializes cited, temporally eligible Memories whose complete lineage is
contained in the selected evidence window. `include: ["conflicts"]` still returns an empty array. The current Memory
atom allows one active value per single-valued slot and has no unresolved-dispute state, so Brain
will not mislabel ordinary historical changes as conflicts. Use `listMemories` for browsing and do
not present Context conflicts as complete.

## Objects do not arbitrate Context

Accepted Objects are stored and readable, but they do not yet resolve competing Memory claims
inside `createContext`.

## Ownership arbitration is partial

Ownership claims are returned, but ownership is not enforced inside every retrieval window.
The private spine does enforce operation scopes and forced row-level tenant isolation; those
controls do not make an unresolved ownership claim safe to promote to self.

## Trace durability depends on the engine

The public `InMemoryStore` sandbox keeps bounded process-local traces. Private `SpineStore`
deployments persist bounded trace receipts in Postgres and tombstone deleted Record pointers.

## Record deletion follows source custody

`forgetRecord` permanently erases API-origin Records and quarantines partially supported derived
rows. Externally reconciled Records return `403 record_not_erasable`: delete at their origin and
let Brain reconcile, or forget the whole Brain. `forgetBrain` performs the terminal tenant
cascade and leaves one content-free durable receipt.

## Sandbox and spine are different

The public Cloud Run sandbox uses `InMemoryStore`. It proves request/response behavior and the
developer experience, never durable or real-corpus memory.

## Latency is a live trade

Warm and cold latency depend on the selected retrieval/rewrite path and the backing corpus. Treat
all published numbers as dated, dataset-tagged measurements rather than an SLA.

## Brain Mac is a bounded customer slice

Brain Mac's read-only four-operation migration is ready. The visible Ask/Search experience and
write paths have not moved onto the Memory API yet.
