Semester 5 Common Failure Modes

Use this page during weekly review and before the checkpoint gate. These are the ways a learner can appear busy while still failing the semester's real intent.


Failure Mode Table

Failure modeRepair evidence
Explaining concurrency with slogans instead of interleavings and invariants.Add one concrete artifact proving the opposite: a trace, test, proof, benchmark, review note, or decision record.
Treating network calls as local function calls.Add one concrete artifact proving the opposite: a trace, test, proof, benchmark, review note, or decision record.
Ignoring timeouts, retries, cancellation, and backpressure.Add one concrete artifact proving the opposite: a trace, test, proof, benchmark, review note, or decision record.
Reading protocol docs without capturing packets or logs.Add one concrete artifact proving the opposite: a trace, test, proof, benchmark, review note, or decision record.

Weekly Review Prompt

At the end of each week, answer these in writing:

  1. Which failure mode was most tempting this week?
  2. What evidence shows you avoided or repaired it?
  3. What will you change in next week's study plan?
  4. Which older semester skill did this weakness depend on?

Do Not Advance If

  • you can only describe the topic using resource titles rather than examples
  • your artifact has no tests, traces, diagrams, or written reasoning
  • you cannot explain the hardest mistake you corrected
  • your checkpoint answers depend heavily on copied notes or solution videos
