Ruby / Integration: data, resources, runtime evidence, and trust

Ruby โ€” Integration: data, resources, runtime evidence, and trust

Connect validated JSON, IO ownership, dependencies, concurrency, controlled loading, and an offline archive capstone.

What you will learn

  • Explain each guaranteeโ€™s owner, environment, and evidence without overstating local examples.

  1. Turn decoded JSON into a validated archive record

    Separate syntax decoding, String-keyed structure, domain limits, explicit field selection, and safe rejection.

    Start learning

  2. Own IO lifetimes and text boundaries

    Use block-owned resources, StringIO fixtures, byte and encoding checks, and bounded consumption without claiming real filesystem execution.

    Start learning

  3. Make checks deterministic and dependencies explicit

    Separate Ruby syntax, behavior checks, gem resolution, runtime version, and platform evidence in an isolated project.

    Start learning

  4. Choose concurrency with explicit state and lifetime ownership

    Distinguish threads, mutex-protected invariants, cooperative fibers, and version-scoped Ractor boundaries without universal parallelism claims.

    Start learning

  5. Keep loading and dispatch separate from untrusted data

    Use fixed load paths, closed action maps, explicit data parsing, and bounded inputs without turning user text into executable Ruby.

    Start learning

  6. Review a typed archive-import policy and its limits

    Combine strict conversion, explicit result objects, pattern handling, complete rejection counts, and honest evidence in an offline capstone.
