Use this page when you are about to move on and want an honest readiness bar. Reading a module once is not the same thing as being ready for the next one. These checkpoints are meant to tell you whether the next module will build on stable understanding or on vague recognition.

How to use this page

For each module:

  1. answer the checkpoint question without looking at the text
  2. run the listed proof or inspection route
  3. stop if you still cannot explain the result in plain language

If you need to reread, reread the narrowest lesson that matches the gap instead of the whole module.

Readiness table

Module You are ready to move on when you can explain... Quick proof or inspection route Go back when...
Module 01 why rerunning commands is weaker than explicit state contracts Capstone Guide or make PROGRAM=reproducible-research/deep-dive-dvc capstone-tour you are still treating "it runs again" as the whole reproducibility story
Module 02 why paths locate content while pointers identify it, and why identity can survive after recoverability is lost make PROGRAM=reproducible-research/deep-dive-dvc capstone-data-identity-audit you cannot identify which layer supplied restored bytes or explain the pointer-only failure
Module 03 why declared runtime drift triggers a rebuild while hidden process state can preserve stale meaning make PROGRAM=reproducible-research/deep-dive-dvc capstone-runtime-contract-audit you treat empty status or forced execution as proof that the runtime contract is complete
Module 04 why declared file and parameter changes become stale while hidden influences and undeclared output loss remain invisible make PROGRAM=reproducible-research/deep-dive-dvc capstone-stage-contract-audit you cannot connect each status receipt to the semantic value or missing artifact it leaves behind
Module 05 why the same numeric movement can be accepted or rejected when population, controls, schema, units, or evidence change make PROGRAM=reproducible-research/deep-dive-dvc capstone-metric-contract-audit you treat arithmetic, matching keys, or row counts as proof that two metric claims are comparable
Module 06 why successful execution, valid comparison, policy value, and authorized promotion are separate experiment gates make PROGRAM=reproducible-research/deep-dive-dvc capstone-experiment-comparability-audit you rank candidates before verifying baseline, intent, changed controls, population, and metric continuity
Module 07 why discovery, object availability, Git completeness, recorded execution, review authority, and result meaning must all survive a cache-cold handoff make PROGRAM=reproducible-research/deep-dive-dvc capstone-reviewer-handoff-audit you treat successful pull or reproduction as proof that the submitted handoff was complete and reviewable
Module 08 what survives local loss and what only looked durable make PROGRAM=reproducible-research/deep-dive-dvc capstone-recovery-review you still blur local convenience with remote-backed recovery guarantees
Module 09 what is safe for downstream trust and why it is smaller than the whole repository make PROGRAM=reproducible-research/deep-dive-dvc capstone-release-review the promoted bundle still feels like a raw dump of internal state
Module 10 how to improve or migrate the repository without losing proof and trust make PROGRAM=reproducible-research/deep-dive-dvc capstone-confirm your migration plan is mostly taste instead of preserved evidence

Common false positives

Do not call a module done just because:

  • the commands looked familiar
  • you can repeat the vocabulary
  • the strongest route passed once
  • you can follow the capstone without naming why the evidence matters

Those usually mean you have seen the surface, not learned the boundary.
