Report readiness by dependency instead of waiting blindly
Bootstrap sleeps thirty seconds, then starts the application even if object storage is still initializing or the database failed permanently.

Project context
A fictional support portal requires a database, cache, object store, and mail catcher. Setup lives in personal notes, reset scripts sometimes target shared resources, and offline work fails after package caches are cleared. Build a local-only development contract with synthetic data; no shared staging system or production credentials are supplied.
Setup prerequisites
- Environment variables
- Service health
- Database migrations
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
Acceptance criteria
- Each dependency has a bounded identity-aware readiness probe
- Transient and terminal failures have separate retry behavior
- Overall report shows ready, waiting, failed, and skipped dependencies
Implementation constraints
- Use injected time and local probes; fixed sleep is not readiness.
Verification to include
- Start dependencies with staggered readiness and complete when all required services pass.
- Return a permanent schema error and stop retrying with an actionable report.
Deliverables
- Dependency readiness graph and timing tests
Rollout and recovery
Display reports beside the existing startup path before enforcing them.
Value of the work
For the engineer: Practice developer-environment automation, safe reset boundaries, portability, and diagnostic quality.
For the team: Reduce onboarding and support cost while making local dependencies and destructive operations explicit.
Evidence boundaries
Outcome Evidence: Tests, patches, and runbooks are requested deliverables. They become Outcome Evidence only through a qualified Mission and immutable Evidence IDs.
Ownership Evidence: Independent adaptation must be observed under a declared verification policy and cite immutable Evidence IDs. Completing a planning ticket establishes no Ownership Evidence.
