Who it is for
Agent builders, enterprise AI teams, and partners that need durable judgment retrieval without exposing raw memory.
Problem it solves
It gives agents a governed way to retrieve cited evidence from durable decisions, wiki graph context, hot cache, scoped brain memory, and specialist brains without silent fallback or route-local search drift.
Activation model
Self-serve reader license for public/catalog-safe retrieval, with assisted enterprise install profiles for custom tenant scope, audit destination, data-tier ceiling, allowed/denied brain regions, and search-depth policy.
Proof and source paths
- Governed retrieval finish spec exists
- MCP tool wrapper exposes stackfast.judgment.retrieve
- Retrieval supports canonical-answer exact returns, explicit-miss metadata, and progressive depth
- Specialist-brain federation is ratified and executed
- Shared context loader supports dual search, graph, Hebbian, wiki cache, and tier confidence

Capabilities
judgment retrieve
mcpRetrieve scoped evidence packs from durable StackFast judgment memory with visible miss, depth, and source metadata.
Agent use
Calls stackfast.judgment.retrieve through the governed MCP rail using tenant scope, rail profile, data-tier ceiling, MASK profile, canonical-answer exact-return detection, progressive search depth, explicit-miss semantics, trace IDs, and bounded specialist-brain federation.
Connector proof
Catalog is not the same as customer-ready.
This product only becomes market-ready after a real host mounts the entitled tools, a safe call succeeds, metering records the event, and a customer-safe receipt exists. Until then, the page shows the strongest proven status without rounding up.
Catalog
Runtime registry and product manifest are present.
Entitlement
Execution requires OAuth or storefront entitlement scope.
Callable
Callable tool proof is incomplete.
Metering
Metering waits on callable execution.
Customer validated
Pending fresh host-surface call receipt.
Runtime registry status
Primary registry
stackfast.ai/api/mcp
Status
partial public mcp
Install gate
Governed Brain Query remains inquiry-only until tenant audit, BYOC install profiles, customer auth contracts, and non-retrieval write/feed rails are exposed or explicitly deferred.
Callable tools

- Retrieval is live and callable with canonical-answer exact returns, progressive depth, explicit-miss metadata, rail profiles, and specialist federation.
- Generation, deliberation, decision-close, and feed/write operations remain separate product-spec capabilities, not public MCP retrieval tools.
