Builds admin-configurable navigation in ASP.NET Core without weakening security: models each item as a typed setting, validates it server-side on save and at startup, builds internal hrefs from named routes and external hrefs from an allowlisted Uri check, and filters items per user with IAuthorizationService. Use 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 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…
Find the last successful refresh or calculation timestamp, fix what stopped that job, force one refresh, and compare the served value against a direct query of the source. Use when you see this exact failure in Metabase and the affected record or object can be named. Not for a different Metabase error with another mes…
Walk the chain in order and test each hand off with one known record, fix the first hand off where the record disappears, and add a log line at that hand off. Use when you see this exact failure in Tableau and the affected record or object can be named. Not for a different Tableau error with another message, or for ge…

Fixes a Tableau extract refresh failing with hyper unable to open the database file so the renewal dashboard stops going stale, by repairing the extract file, path, and refresh environment. Use when scheduled refreshes fail on the extract. Not for a data source connection failure to the live database.
Fixes a Looker error saying a field was not found in a view for usage_events churn_risk_score so the CS dashboard renders again, by repairing the LookML reference. Use when one dashboard or tile errors on the field. Not for a field that never existed in the data.
Explains why backup verification passes while a real restore fails, and closes the gap with boot, application, and full-chain restore tests. Use when SureBackup, check, or verify jobs are green but production restores break. Not for verification jobs that already report errors.
Fixes a Tableau extract refresh that fails because the data source cannot be found by reconnecting the workbook to the published source or the moved file. Use when a scheduled refresh fails after a file or source move. Not for a live connection query error inside a view.

Fixes yum failing with rpmdb open failed (and related rpmdb errors), where the RPM database is corrupt or locked after a killed yum process, a crashed host, or stale Berkley DB locks. Use when every yum and rpm command fails at database open. Not for a single package that fails to install.

Finds the shared file handle behind the I/O operation on closed file flake in parallel pytest runs. Use when the error appears intermittently with xdist. Covers finding module-level or module-scoped file handles, giving each test its own file via tmp_path, and rerunning in parallel. Not for single-process occurrences.
Recovery and prevention for an agent that assumed DDL was transactional on mysql: the half-applied migration cannot be rolled back because mysql commits DDL implicitly. Use when a mysql migration failed midway and left a partial schema. Not for postgres, where transactional DDL usually allows rollback.
How to specify the DSN for pt-online-schema-change's "Cannot connect to MySQL" error: the DSN part syntax, authentication options, and a working command template. Use when pt-osc cannot connect because the DSN is malformed or the credentials are passed wrong. Not for connection failures with a correct DSN (check netwo…
A recovery playbook for golang-migrate's Dirty database version error: how to inspect what the failed migration partially applied, finish or undo it by hand, clear the dirty flag with migrate force, and verify the chain is clean. Use when migrate refuses to run because a version is marked dirty. Not for migrations tha…
Fixes sqlmap's corrupt session file that refuses to resume. Use when sqlmap reports unable to resume previous session on an authorized scan. Not for session files from a different target or sqlmap version.
Fixes Chroma persistent-client crashes when SQLite reports the database is locked. Covers the single-writer requirement, serializing writes across threads and processes, and moving to client/server mode when concurrency is real. Use when a persistent Chroma collection raises OperationalError on writes.
Fixes grype's offline database install when the local archive will not install. Use it when grype db install fails on an airgapped host with a hand-carried tarball. Key trigger: a truncated download or a DB schema version that does not match the grype build.
A fix for Java's 'PKIX path building failed': why the JVM rejects certificate chains that browsers accept (the JVM uses its own cacerts truststore, not the OS store), how to import the missing CA with keytool, and how to verify you hit the right truststore. Use when Java services fail on HTTPS calls, after proxy CA ch…
Fixes DuckDB IOException: Could not open file errors. Use when duckdb cant open a database or data file, when an agent uses a relative path from the wrong working dir, or when the file is locked by another process. Not for SQL errors, for type conversion failures, or for out-of-memory issues.
Fixes a Prisma migration blocked by a failed row in _prisma_migrations after a lost database connection. Use when migrate deploy refuses to run until the failed migration is resolved. Key trigger: a row with finished_at null in _prisma_migrations; choose migrate resolve --applied vs --rolled-back.
