Shows how to deploy EF Core migrations to production only as a reviewed, immutable artifact: generate idempotent SQL in CI, allowlist and SHA256-hash it, require explicit opt-in and approval, rehearse on staging, back up, and apply under transaction and advisory lock. Use for gated production EF Core releases. Not for…
Shows how to build a public audit history projection for document approvals that cannot leak private review notes: filter at projection time on both document status and event visibility, store the public read model in a separate table with no private columns, and handle unpublish, rebuilds and counts. Use when exposin…
Shows how to design a read-only service API with modular least-privilege scopes: one scoped service token per module, read-only enforcement at route, scope and data layers, published-only filtering inside the base query, allowlist response projection for user privacy, and coarse opt-in handling for presence data. Use …
Shows how to build an approval workflow in ASP.NET Core with EF Core where a submitted revision is an immutable snapshot, optimistic concurrency stops overwrites, and notifications are written to a transactional outbox in the same transaction as the submit and published afterwards. Use when approvers must approve exac…
Fixes this failure: judge VM patch compliance from inside the guest after the snapshot revert point: tag snapshots taken for patching, alert when a patched VM is reverted. Use when the exact error or symptom in the title appears. Not for a different error, tool, or a manual process with no such failure.
forget cannot remove snapshots from a repository mounted read only, whether by filesystem mount options, an object store bucket policy, or a storage appliance presenting a locked tier: determine which layer enforces the read-only state and move the maintenance operation to where writes are allowed, or adjust the mount…
Fixes this failure: pin the production page ID in the automation's production configuration, add a startup check that the page ID matches the environment. Use when the exact error or symptom in the title appears. Not for a different error, tool, or a manual process with no such failure.
Fixes an agent whose pagination missed the newest backup when listing restic snapshots, causing the check to test a stale point. Use when the agent verifies an older snapshot than the latest. Not for a repository where the newest snapshot genuinely failed to be created.
Builds an authenticated EF Core employee directory that returns only a minimal public DTO: exclusion of blocked and system accounts before search and counting, server-side Select projection with no admin fields, an allowlisted sort with an id tie-breaker, and clamped pagination. Use when a directory endpoint returns u…
