    Place Research Data Intentionally

    Decide where fictional project data belongs: who owns it, who may see it, where it must survive and where it will be used. Move no real data.

    Before you start#

    Research data includes measurements, derived results and records explaining them. The main approved copy is the version the owner treats as correct. Sensitivity describes disclosure/access restrictions; durability describes survival; retention states how long a copy must be kept.

    Fictional beam item Recovery need Decision
    Measurements Cannot be reconstructed Owner approves classification and durable main copy
    Derived report Useful result with provenance Collaborators need an approved recoverable copy
    Mesh cache Can be rebuilt from recorded inputs Compute location and safe cleanup condition

    A checksum is a calculated fingerprint comparing contents. It establishes neither permission nor durability. Keep code separate from data and results.

    A copy is readable and its checksum matches. Which placement decisions remain? Try the decisions before opening the explanation.

    Separate a verified copy from an approved main copy

    Verify contents, then confirm the owner's approved service, access, backup/recovery and retention. Temporary work does not replace the durable main copy. Stage high-I/O inputs to approved compute storage; verify needed output back before owner-approved cleanup.

    Choose storage by ownership, access, recovery and lifetime; a filename does not establish those properties.

    Steps

    Use the fictional beam project. Decide approval, durability, computation and retention before choosing a location. Move or delete no real data.

    1. 01

      Classify sensitivity

      Read and answer on this web page

      Use the fictional measurements, report and replaceable mesh above. Classification comes from the information owner and context, not a file extension. Do not use real project details here.

      Look forThe classification is explicit and justified.

      Explanation and help
      What this means
      Name an information owner.
      Safe recovery
      Stop placement until the project owner resolves the classification.
    2. 02

      Name the owner

      Read and answer on this web page

      The fictional project owner decides access and retention. Holding a downloaded copy does not make the analyst the information owner.

      Look forOne accountable owner is named.

      Explanation and help
      What this means
      Decide durability and collaboration needs.
      Safe recovery
      Ask the supervisor; do not self-authorize access.
    3. 03

      Decide how long it must survive

      Read and answer on this web page

      The measurements cannot be reconstructed; the mesh can. Compare recovery needs before assigning a location. A checksum verifies equal contents, not backup or authorization.

      Look forIrreplaceable material is assigned to approved durable storage.

      Explanation and help
      What this means
      Decide where collaborators and compute need it.
      Safe recovery
      Do not leave the only copy in scratch, Blade D:, or a laptop.
    4. 04

      Match collaboration and compute locality

      Read and answer on this web page

      Keep code in a separate Git clone. Choose approved shared storage for measurements/report and approved compute storage for high-I/O working copies. Do not put data or checkpoints in Git.

      Look forThe location supports the actual collaborators and workload.

      Explanation and help
      What this means
      Define retention and cleanup.
      Safe recovery
      Do not run high-I/O Euler work directly against external NAS.
    5. 05

      Record retention and cleanup

      Read and answer on this web page

      Cleanup is safe only after required outputs reach verified durable storage and the owner-approved retention rule permits removal. No actual deletion is performed.

      Look forEvery temporary copy has an end condition.

      Explanation and help
      What this means
      Complete the fictional placements.
      Safe recovery
      Keep the file or result unchanged until the person responsible for retention has decided what must happen.
    6. 06

      Complete each placement

      Read and answer on this web page

      Answer the six fictional decisions. This assessment checks choices; any extra location map is optional private practice, not a public upload.

      Look forNo sensitive or durable file or result is assigned to unapproved temporary storage.

      Explanation and help
      What this means
      Run Check my work.
      Safe recovery
      Correct the first placement with an unresolved owner or durability rule.

    Practise

    One practice question. It does not affect your progress.

    01A report copied into temporary storage has the same checksum as its source. Is its placement safe for handover?
    See an explanation

    Checksums compare contents. They do not establish approval, backup, access or retention. Verify the needed result in owner-approved durable storage before removing other copies.

    If Blocked#

    Do not create another ad hoc copy. Record the unresolved owner, classification, or storage decision and ask the supervisor. Use the NAS guide only after the assigned supervisor folder is known.

    Understand Before Accepting AI Output#

    An agent cannot decide ownership, classification, retention, or approved services. It must not scan or reorganize real project data to complete this exercise.
