Specifies least privilege, validation, isolation, budgets, retries, cancellation, audit evidence, and safe failure handling for governed analytics tool gateway, so adopters can expose narrow metric operations through one authorization, validation, budgeting...
Package status: reference context ready for human review. The contract and test scenarios are complete, but no claim is made that an adopting implementation has passed them.
Decision
For Governed analytics tool gateway, implement the interface with independent access and resilience controls so adopters can expose narrow metric operations through one authorization, validation, budgeting, compilation, and audit boundary. The gateway accepts semantic metric requests only; raw SQL, database object names, credentials, and write operations are not part of its public contract. This is a reference contract: database products, numeric budgets, jurisdictions, retention, organizational defaults, and accountable owners remain explicit adoption choices.
Scope
- The Governed analytics tool gateway actors, inputs, outputs, states, versions, and externally visible outcomes needed to expose narrow metric operations through one authorization, validation, budgeting, compilation, and audit boundary.
- The role-specific focus of this block: implement the interface with independent access and resilience controls, including primary, cached, asynchronous, export, support, and recovery paths where applicable.
- Adoption-specific configuration, ownership, rollout, evidence retention, and review responsibilities needed to use the contract safely.
Outside this block
- The gateway accepts semantic metric requests only; raw SQL, database object names, credentials, and write operations are not part of its public contract.
- Choosing a universal database, model, renderer, vendor, numeric threshold, retention period, timezone, jurisdiction, or service-level objective.
- Claiming that packaged scenarios ran against a downstream implementation or that this reference grants security, privacy, accessibility, analytical, or legal approval.
Contract
- The implemented Governed analytics tool gateway boundary enforces this rule: Public operations are allowlisted metric discovery, description, query, comparison, breakdown, freshness, and result retrieval; no generic execute statement operation exists.
- The implemented Governed analytics tool gateway boundary enforces this rule: The gateway derives identity, tenant, role, assignments, and purpose from trusted authentication context and treats model arguments only as requested scope.
- The implemented Governed analytics tool gateway boundary enforces this rule: It validates metric version, subject, periods, dimensions, filters, grain, minimum population, and budgets before compiling any connector request.
- The implemented Governed analytics tool gateway boundary enforces this rule: Authorization is applied before aggregation and again before result delivery, cache reuse, export, drill-down, or asynchronous retrieval.
- The implemented Governed analytics tool gateway boundary enforces this rule: A database-specific compiler generates parameterized queries against curated analytical objects; generated text is never accepted back from the model.
- The implemented Governed analytics tool gateway boundary enforces this rule: Results follow one schema containing metric descriptions, values, units, periods, quality, freshness, access trimming, warnings, and provenance.
- The implemented Governed analytics tool gateway boundary enforces this rule: Error codes distinguish invalid, ambiguous, unauthorized, unsupported, over-budget, stale, partial, dependency, and internal failures without leaking protected existence.
- The implemented Governed analytics tool gateway boundary enforces this rule: Every operation has a correlation ID, bounded deadline, cancellation path, rate and cost accounting, safe audit evidence, and a terminal state.
Implementation guidance
- Layer host authentication, gateway authorization, compiler allowlists, connector controls, and database privileges so no single hint grants safety.
- Keep credentials outside prompts and model-visible state, rotate them through the adopting platform, and scope them to curated resources.
- Apply hard limits before external work and propagate deadline, cancellation, correlation, and terminal status through every hop.
- Redact errors and telemetry while retaining safe references that an operator can correlate with backend evidence.
Failure handling and safeguards
- For Governed analytics tool gateway, Any request containing SQL, unknown operators, unregistered fields, or caller-asserted authority is rejected before connector routing.
- For Governed analytics tool gateway, If a connector exceeds its deadline or budget, the gateway cancels where supported and returns a terminal structured error with no partial false success.
- For Governed analytics tool gateway, A cache key or async handle that does not match current caller policy returns a non-enumerating denial and cannot reveal prior results.
Verification and operations
- For the security evidence of Governed analytics tool gateway, fuzz schemas, identifiers, filters, encodings, handles, and tool errors to prove that no input crosses into an executable SQL position.
- For the security evidence of Governed analytics tool gateway, run a role-by-operation-by-subject matrix across direct, cached, asynchronous, export, and drill-down paths.
- For the security evidence of Governed analytics tool gateway, inject connector timeout, cancellation failure, stale catalog, partial data, and audit sink failure and verify bounded terminal behavior.
Adoption assumptions
- The adopting product has authenticated identity, a versioned authorization policy, owned metric definitions, bounded telemetry, and a controlled path for change.
- Names and values in the example are fictional adoption fixtures, not universal defaults, production credentials, performance promises, or business targets.
- Referenced specifications constrain protocol, security, accessibility, or vendor behavior; the adopting team must confirm current applicability before promotion.
The executable-looking examples in this package are fixtures and acceptance contracts. Run the collection validator to check structure and metadata, then translate and execute the scenarios in the target repository before recording implementation evidence.
