Price a throwaway sandbox across AWS, GCP, Azure, Vercel, Fly.io, Railway, Replit, Codespaces and Gitpod, then audit what forgetting to tear it down actually costs per forgotten day.

Drop any game save file — Minecraft NBT, Unreal Engine GVAS, Palworld containers, JSON/XML/INI/Lua text saves, SQLite profiles — and get the detected format, engine versions, key progress fields and a bounded structural tree.

Validate W3C Trace Context propagation headers end to end: traceparent (version / 16-byte trace-id / 8-byte parent-id / trace-flags), tracestate (≤32 list members, tenant keys), baggage (percent-encoded values + opaque properties), OTLP export Content-Type, the gRPC grpc-trace-context-bin 25-byte binary context — plus a two-header correlation round-trip with a random child span-id collision check.

Decompose a directed or undirected graph with Tarjan's 1972 iterative SCC algorithm cross-checked against Kosaraju's two-pass; find articulation points and bridges via low-links; build the condensation DAG with a Kahn topological order; report cycles (nodes on cycles, self-loops) and depth-limited BFS/DFS traversals.

Parse RFC 8288 Link headers with the spec appendix-B algorithm, resolve relative URI-references against a base URL, classify rel types against the IANA registry, validate preload/prefetch hints, and simulate how a rel="next" pagination crawler walks your responses — including cycle detection.
