Read the first diagram as a timing map: this guide is for a named pressure, not for wandering the whole course-book. Read the second diagram as the guide loop: arrive with a concrete question, use only the matching sections, then leave with one smaller and more honest next move.

This page exists because strong module titles are not enough. A learner should be able to ask, for every module, “what is this module promising me, and how will I know it was delivered?”

Use this guide when a title sounds right but still feels too broad, too compressed, or too weakly tied to proof.

How To Read This Page

Each row names four things:

  • the module promise
  • the boundary of that promise
  • the learner outcome the module should leave behind
  • the first honest capstone corroboration route

If a module page drifts away from this contract, the drift should become visible here.

Promise Table

Module Promise Boundary Learner outcome First corroboration
01 Why Reproducibility Fails teach why reruns are weaker than explicit state contracts failure modes, trust questions, state layers explain why “it runs again” is not enough capstone-tour
02 Data Identity teach why content-addressed identity matters more than paths workspace, cache, remote, lockfile identity distinguish location from durable state identity capstone-verify
03 Environments As Inputs teach runtime context as part of declared state environment, toolchain, repo code, validation routes explain why execution context belongs in the reproducibility story capstone-verify
04 Truthful Pipelines teach dvc.yaml and dvc.lock as one explicit execution contract stages, deps, outs, params, and recorded execution state review whether a pipeline edge is truly declared capstone-repro
05 Metrics, Parameters, And Meaning teach semantic comparability instead of metric folklore params, metrics, reports, publish evidence say what a metric comparison is allowed to mean capstone-verify
06 Experiments Without Chaos teach controlled variation without baseline damage experiment runs, baseline, params, comparison routes explain how changed runs stay comparable to the baseline capstone-experiment-review
07 Collaboration And CI teach social contracts around state and verification reviewability, CI gates, handoff trust, repo policy explain what another person should be able to rerun and review capstone-confirm
08 Incident Survival teach production recovery and durability boundaries cache loss, remote-backed restore, crisis review explain what survives local loss and why capstone-recovery-review
09 Promotion And Auditability teach promotion as a smaller trusted boundary publish surfaces, manifests, release review, promotion evidence review what is safe for downstream trust capstone-release-review
10 Tool Boundaries teach stewardship, migration, and handoff judgment governance, anti-patterns, limits, migration review decide whether DVC should keep owning the concern capstone-confirm

Promise Failures This Page Guards Against

When module titles are strong but unchecked, courses usually fail in one of four ways:

  • the title promises judgment, but the module only delivers commands
  • the title promises operations, but the proof routes stay abstract
  • the title promises promotion or recovery, but the capstone surface never corroborates it
  • the title promises governance, but the repository review route remains blurry

This page makes those failures visible before they harden into course drift.
