Module 01 advanced
Enforce boundaries around model execution
Connect model loading, request parsing, retrieval access, tool permissions, and output handling to deployment controls with independently testable security properties.
- 01
Authorize an artifact before interpreting its model representation
Distinguish tensor-format restrictions, restricted unpickling, executable model code, artifact identity, and the remaining runtime trust boundary.
30 min - 02
Bound the full loading path before reserving a device
Apply independent download, archive expansion, metadata, tensor, host-memory, device-memory and concurrency budgets instead of treating file size as peak load cost.
30 min - 03
Validate bounded representations before expensive inference work
Combine transport, decoded media, tensor, tokenizer and generation limits while keeping syntactic validation separate from authorization and model behavior.
30 min - 04
Authorize the resolved tenant, model, version and adapter on every path
Bind authenticated caller context to canonical serving resources across streaming, batch, fallback, adapter activation and result retrieval paths.
30 min - 05
Recheck document permissions when retrieval evidence is consumed
Bind retrieval, reranking, prompt construction, citations and cached answers to current document policy rather than ingest-time visibility or query-text similarity.
30 min - 06
Let a trusted broker issue only the authority a tool action needs
Keep credentials out of model context and bind short-lived tool access to the authenticated caller, approved resource, action, audience and current policy.
30 min - 07
Keep generated text and structured proposals outside interpreter authority
Validate output representations, authorize proposed operations, and use the correct boundary for HTML, SQL, shell arguments and other downstream consumers.
30 min - 08
Reserve physical work as well as counting incoming requests
Combine tenant/account request limits, concurrency, token/work reservations and verified cancellation so distributed retries and variable-cost inference cannot bypass the intended budget.
30 min - 09
Attribute serving decisions without turning logs into a secret store
Capture trusted actor/resource/policy context, distinguish authorization decisions from completed effects, and protect bounded event delivery and retention.
30 min - 10
Validate enforcement independently of model cooperation
Use controlled allowed/denied pairs, backend canaries, policy-change fixtures and bounded fault injection to state what each serving control actually establishes.
