Defines actors, content states, rules, review paths, messages, appeals, and edge cases for moderation queues. This reference fixes the adoption boundary, failure behavior, and observable evidence while leaving 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 Moderation queues, adopt a versioned content record and moderation state machine. Make the user-visible promise, exclusions, authority, and failure response explicit while leaving measured thresholds as adoption choices. 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 Moderation queues actors, inputs, outputs, states, policy or schema versions, and externally visible outcomes described by this requirements 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
- Store original input separately from normalized or rendered output and identify the transformer and policy version used.
- Sanitize for the actual output context; parsing, Markdown conversion, and MIME labels do not make active content trusted.
- Authorize create, edit, publish, moderate, appeal, and delete actions independently and retain the material decision trail.
- Represent pending, allowed, restricted, rejected, appealed, and removed states explicitly rather than overloading visibility flags.
- State which actor receives which outcome under each material state, including unavailable, unauthorized, empty, and partial conditions.
- Mark configurable limits and policies as choices with owners; do not present sample values as universal requirements.
- Create immutable review items with content and policy versions, reason, priority source, jurisdiction, risk class, eligibility, and service target.
- Lease work to one reviewer, prevent duplicate final decisions, expose backlog age and override history, and keep automated priority from concealing starvation or appeals.
Implementation guidance
- Review the contract with product, implementation, operations, security, and affected users before promoting it beyond review.
- Model Moderation queues inputs, outputs, actors, states, invariants, side effects, and evidence before selecting framework or vendor details.
- Store the applicable Moderation queues 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
- Unsafe or unclassifiable content remains unavailable by default and enters a bounded review or rejection path.
- Invalid or contradictory Moderation queues 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
- Map each promise and exclusion to at least one observable scenario and confirm that no two states require contradictory outcomes.
- Monitor Moderation queues 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.
