Lists recommended PureIntent blocks, project structure, implementation sequence, tests, and launch checklist for the job board solution. 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 Job board, adopt a bounded product scope and an explicit composition of independently adoptable blocks. Implement the behavior through one authoritative write path, typed interfaces, explicit state, and idempotent side-effect handling. This implementation block focuses specifically on starter bundle and delivery. 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 Job board actors, inputs, outputs, states, policy or schema versions, and externally visible outcomes required for the starter bundle and delivery focus of this implementation 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
- Identify target actors and core journeys before selecting infrastructure; every included block traces to a journey or cross-cutting risk.
- Separate MVP commitments, later capabilities, and non-goals so the starter does not imply an unlimited product scope.
- Define service, data, permission, integration, and operational boundaries without forcing one vendor or deployment topology.
- List the verification and launch evidence required from each composed block and keep its review status visible.
- Validate inputs once at the boundary and preserve the normalized representation used by downstream logic.
- Persist the business transition before or atomically with an outbox record; consumers deduplicate by durable operation identity.
- Represent listings with owner, employer, location or remote policy, compensation disclosure, employment type, publication state, opening and closing times, moderation, and expiry.
- Authorize employer and applicant actions separately, protect application and demographic data, prevent duplicate or deceptive listings, and preserve status and communication evidence through withdrawal or closure.
- For the starter bundle and delivery variant, enforce this declared boundary: lists recommended pureintent blocks, project structure, implementation sequence, tests, and launch checklist for the job board solution.
Implementation guidance
- Ship additive storage and interface changes first, backfill observably, then retire old paths after compatibility evidence.
- Model Job board inputs, outputs, actors, states, invariants, side effects, and evidence before selecting framework or vendor details.
- Store the applicable Job board 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
- If a required block or launch control is unresolved, the pack reports the gap and does not label the solution production-ready.
- Invalid or contradictory Job board 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
- Inject dependency failure before and after persistence and prove that retry converges on one externally visible outcome.
- Monitor Job board 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.
