Covers permission test matrices, audit evidence, migration checks, and incident investigation for public and private resources. It fixes adoption boundaries and observable failure evidence while keeping environment-specific limits configurable.
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 Public and private resources, adopt a centralized server-side policy decision using authenticated subject and resource context. Treat the block as a release and regression contract built from representative positive, boundary, denial, failure, and recovery cases. This package is a reference contract: the adopting team must choose numeric limits, providers, jurisdictions, and operational owners from evidence in its own environment.
Scope
- The Public and private resources actors, inputs, outputs, states, policy or schema versions, and externally visible outcomes described by this testing block.
- Primary and alternate interfaces, background work, caches, integrations, support paths, and evidence that can exercise the same boundary.
- Adoption-specific configuration, rollout, recovery, and verification responsibilities needed to apply the reference safely.
Outside this block
- Choosing a universal vendor, framework, jurisdiction, numeric threshold, retention period, or service-level objective for every adopter.
- Claiming that packaged scenarios have run against a downstream implementation or that this reference grants legal, security, or accessibility certification.
Contract
- Deny by default when subject, action, resource ownership, tenant, or policy version is missing or contradictory.
- Apply the same resource scope to primary records, indexes, caches, files, jobs, exports, aggregates, and support tooling.
- Do not treat a hidden UI control, client claim, route name, or hard-to-guess identifier as authorization evidence.
- Record policy version, subject, resource, action, result, and safe reason for privileged and denied decisions.
- Record fixture version, environment, configuration, observed result, and evidence location for every decision-bearing run.
- Separate product failure, dependency failure, test-infrastructure failure, and inconclusive evidence in reports.
- Represent visibility as an explicit server-owned policy state with subject, tenant, audience, grants, effective version, and transition history rather than as an untrusted URL property.
- Propagate privacy changes to caches, search, previews, counts, exports, shares, notifications, and background jobs and fail closed while any authoritative projection is stale.
Implementation guidance
- Build the smallest deterministic fixture set that spans risk classes, then add production-derived cases only after privacy-safe review.
- Model Public and private resources inputs, outputs, actors, states, invariants, side effects, and evidence before selecting framework or vendor details.
- Store the applicable Public and private resources contract or policy version with material state so migrations, replay, and support decisions remain attributable.
- Introduce the path behind controlled rollout, compare expected and observed outcomes, and keep a tested recovery route until adoption evidence is complete.
Failure handling and safeguards
- Policy service or context failure denies the protected operation and emits a bounded, non-sensitive investigation signal.
- Invalid or contradictory Public and private resources state is rejected or quarantined; the implementation never guesses a value that broadens authority or duplicates an effect.
- Retries are bounded and use durable identity; after exhaustion, work reaches an inspectable terminal state with an accountable owner.
Verification and operations
- Run the suite twice from a clean state and confirm that ordering, retries, and parallel execution do not change the verdict.
- Monitor Public and private resources success, denial, validation failure, dependency failure, retry exhaustion, and recovery by contract version without sensitive payload dimensions.
- Re-run paired positive and negative fixtures after policy, schema, dependency, migration, or boundary changes and preserve the resulting evidence.
Adoption assumptions
- Names and values in the example are a concrete fixture, not universal defaults; adopters replace them through documented evidence and ownership.
- The adopting system can provide authenticated identity, durable operation or record versions, bounded telemetry, and a controlled path for change.
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.
