WHAT HAPPENS WHEN APDD IS WRONG - OR AN APPLICATION FAILS?
Make the failure visible. Make the correction earn its place.
APDD does not define reliability as never failing. Failures, contradictions, unexpected results, and weak claims become inspectable inputs to correction. A technically completed artifact is not automatically a successful result.
The difference is evidence.
If the intended result differs from reality, APDD should not hide the gap or quietly replace the story. Ask what failed, under what conditions, what survived, what evidence exposed the failure, what correction is justified, whether the correction survives retesting, and what remains uncertain.
OBSERVE -> COMPARE INTENTION WITH RESULT -> LOCATE THE FAILURE -> PRESERVE WHAT SURVIVED -> CORRECT ONLY WHAT EARNED CORRECTION -> RETEST -> TRIAL-OF-FIRE -> UPDATE ONLY IF EARNED
THE CORRECTION PATH
Failure is investigated, not merely replaced.
1. Evidence
What actually happened? Separate the observed result from the expected result and from the explanation.
2. Failure Region
Locate what failed without assuming everything failed. Preserve what still survives examination.
3. Limits
State where the result should stop. A result earned under one condition does not automatically transfer to another.
4. Correct
Change what the evidence earns. Do not rewrite working parts merely because one part failed.
5. Retest
A better explanation is not enough. Run the corrected behavior again and look for regression or a new failure.
6. Trial-of-Fire
Give the weakness a meaningful chance to reveal itself. Confidence rises only when behavior survives examination.
WHAT REAL WORK HAS TAUGHT APDD
Correction changes practice.
A file is not the result.
Producing an artifact does not prove that the intended human result was achieved. APDD now separates technical completion from outcome verification.
Limit: Verification must match the actual use case.
A demonstration is not reliability.
One successful run can establish possibility. Reliability requires repeated performance, varied conditions, failure examination, correction, and regression testing.
Limit: A prototype should remain labeled as a prototype until stronger evidence exists.
Risk is not timing.
Evidence that conditions are risky does not automatically establish when an event will occur. APDD separates those claims instead of collapsing them.
Limit: Historical evidence does not guarantee a future event or its timing.
Movement is not understanding.
Animation can attract attention without explaining a relationship. APDD treats motion as useful only when it helps the viewer understand what changed and why it matters.
Limit: Visual behavior still requires human comprehension testing.
REASONING AND OUTCOME ARE NOT THE SAME THING
APDD tests APDD itself.
A correct outcome does not automatically prove that the reasoning was good. A wrong outcome does not automatically prove that every part of the reasoning was bad. APDD examines the relationship between the method, the evidence, the result, and the conditions under which the result occurred.
No dead-end conclusions. A failure should leave the next useful investigative question visible.
FAILURE HAS TO BE DEFINED
You cannot correct a result if success was never made clear.
Correction begins before something breaks. The intended result, important conditions, meaningful boundaries, and evidence of completion should be clear enough that reality can disagree with them. Otherwise almost any outcome can be explained afterward as acceptable. APDD treats that ambiguity as a problem because a system cannot learn reliably from a target that moves whenever the evidence becomes inconvenient.
Different failures also require different responses. A broken link is not the same as a false factual claim. A rendering defect is not the same as an authorization failure. A useful prototype that cannot yet repeat its result has demonstrated possibility but not reliability. By naming the kind of failure, APDD can investigate the relevant region instead of rewriting everything around it.
SEPARATE OBSERVATION FROM EXPLANATION
What happened comes before the story about why it happened.
When something fails, the first useful record is the observed condition: what was attempted, what was expected, what occurred, and under what known circumstances. Explanations can follow, but they should not quietly replace observation. This distinction matters because the first explanation is often incomplete. A network problem may resemble an application defect. A stale file may resemble a failed deployment. A cached page may resemble a missing correction.
APDD therefore treats hypotheses as hypotheses until evidence distinguishes among them. The investigation can compare alternatives, remove variables where practical, reproduce the condition, or test the suspected correction. That reduces the chance of fixing the wrong thing and creating a second defect while the first remains.
PRESERVE WHAT SURVIVED
A local failure does not automatically invalidate the whole system.
Correction should be proportional. If navigation failed but the content remained accurate, the content does not need to be rewritten merely to make the correction feel comprehensive. If one integration failed while independent functions survived, those surviving functions remain evidence. Preserving what works protects both reliability and learning: it shows which relationships actually depended on the failed component.
This is also a form of change control. Smaller justified corrections are easier to inspect, compare, reverse, and retest than broad unbounded rewrites. When a larger architectural change is genuinely required, the evidence should explain why the smaller boundary was insufficient.
RETEST THE CORRECTION, NOT THE INTENTION
A plausible fix is still only a candidate until behavior changes.
Editing code, replacing a file, changing an explanation, or adjusting a workflow can create a correction candidate. Completion requires evidence that the relevant result now behaves as intended. Where consequences justify it, retesting should also look for regression: did the correction repair one path while damaging another?
The test should match the claim. A page returning an HTTP success code does not prove that its navigation is usable. A file existing on a server does not prove that the public version contains the intended content. A successful demonstration does not prove repeated reliability. APDD tries to choose evidence that reaches the level of the statement being made.
WHEN THE CORRECTION FAILS
The failed fix becomes new information.
A correction can be wrong, incomplete, or aimed at the wrong failure region. When that happens, APDD should not protect the correction merely because time was spent producing it. The new result is compared with the previous evidence. What changed? What did not? Did the suspected cause survive the test? Did another dependency become visible?
This is where a failed correction can be valuable. It may eliminate an explanation, reveal an interaction that was hidden, or show that the original boundary was too narrow. The next investigation begins from that evidence rather than from a desire to defend the previous attempt.
VISIBLE LIMITS PROTECT TRUST
Correction includes saying what has not been established.
A corrected result may still have boundaries. It may have been tested on particular devices, under particular data conditions, against a limited sample, or only for the failure that was observed. Those limits should remain visible when they materially affect interpretation. Reliability grows by surviving broader examination; it does not grow because uncertainty was omitted from the description.
That is why APDD distinguishes possibility, tested behavior, and stronger reliability claims. Each can be useful when labeled accurately. Trust is better served by a smaller claim supported by evidence than by a larger claim that testing has not earned.
YOU REMAIN IN CONTROL
Do not accept a correction merely because APDD made it.
Inspect the evidence. Compare the intended result with the observed result. Examine the stated limits. Challenge the correction. Retest where practical. The purpose is not to replace critical thinking, but to make more of the reasoning available for examination.
