What to build

Establish a lightweight performance-and-cost observability baseline for the most expensive public paths: homepage, search, material detail, download, preview, and related background work. The team should be able to see request volume, latency, cache effectiveness, and cost-sensitive behaviors well enough to prioritize future optimizations rationally.

Acceptance criteria

• The project captures a baseline for the key public paths that drive infrastructure cost.
• The baseline includes at least request or query cost, not just correctness metrics.
• Maintainers can compare before/after results for future optimization slices.
• The chosen observability approach is documented for ongoing use.
