On console warnings and the things we don't remove
Removing unused documentation tooling and fixing prop type warnings: small changes that don't ship features but keep the console's warnings meaningful.

Three kinds of drift: currency, ghost flags and passenger types
A currency display bug, a feature flag that never existed in the flagging service, and a passenger type code nobody resolved: three kinds of drift that fail silently.
The shape of shared libraries
A shared library is defined by the shape it presents to its dependents. Two cases make that concrete: an icon component used through an undeclared path, and a one-line logging change that broke a numeric assumption.
Three bugs hiding in a cross-service feature
Building a feature across four services meant coordinating an AI backend, a fare search service, and two frontend components. Along the way: a silent configuration bug, a duplicate event contract, and an HTML injection path.
The scaffolding tax: getting a new service properly bootstrapped
Bootstrapping a new service from a template isn't just renaming things; it's wiring it into the deployment pipeline, getting dependency management right, and building the scaffolding that makes all future work faster.
Folding a conversational search selection into a basket
Saving an option from a conversational flight search into a booking basket needed a new route: a partial update that has to merge a selection into whatever is already there. Plus privacy-aware MCP observability, Copilot context hooks and a naming cleanup.
