Hypothesis-driven debugging replaces that with an explicit method — and the difference in speed compounds dramatically on hard bugs.","## What hypothesis-driven debugging actually means\n\nWatch a junior engineer debug and a senior engineer debug the same problem and the difference is usually not in the tools or the knowledge of the codebase. It's in the *method*.\n\nA junior engineer typically does this: read the error, form a guess about the cause, change something they think might fix it, run again, see what happens, adjust the guess, repeat. The loop is fast but unstructured. Each iteration generates noise without necessarily generating signal. A bug that has multiple possible causes can take hours of this before the right one is found, sometimes by accident.\n\nA senior engineer does something different. They form an explicit list of plausible hypotheses up front, then design a specific test for each that could *rule it out*. They run the tests in order of cheapness — eliminating the easy-to-check hypotheses first — until the search space has shrunk to one. The loop is slower per iteration but converges fast, because each iteration eliminates real possibilities instead of just trying things.\n\nThis is hypothesis-driven debugging. It's not a tool. It's a discipline that's transferable.\n\n## The five principles\n\n**1. Separate symptoms from hypotheses.**\nA symptom is what you observe: \"the request returns 500 errors when the user has a specific account state.\" A hypothesis is a candidate explanation: \"the cache is returning stale data for accounts in that state.\" Conflating them is the source of most debugging dead-ends. Write the symptom down, then list hypotheses *under* it.\n\n**2. Enumerate before testing.**\nThe hypothesis you guess first is rarely the right one. Before running any test, list every plausible hypothesis you can think of. The act of listing forces you to consider categories of causes you'd otherwise skip.\n\n**3. Design tests that falsify, not tests that confirm.**\nA confirmation test (\"if I assume X, the system behaves as expected\") is weak evidence — many hypotheses could be consistent with the same behavior. A falsification test (\"if X were the cause, this specific check would fail; the check passes, so X isn't the cause\") eliminates hypotheses cleanly.\n\n**4. Cheapest tests first.**\nSome hypotheses are expensive to test — they require deploying to staging, simulating production load, or instrumenting code. Others are cheap — a log query, a single curl, a database lookup. Run the cheap tests first regardless of which hypotheses you think are most likely. You'll often eliminate three hypotheses for the cost of testing one.\n\n**5. Stop when one hypothesis explains everything.**\nThe debugging is done when you have one hypothesis that explains every observed symptom, *and* a verification step that confirms it. \"Fixing it\" before you've reached this point is how you ship the wrong fix and discover six months later that the real bug was something else and you were masking it.\n\n## Why this matters more for hard bugs\n\nFor easy bugs, hypothesis-driven debugging is overkill. The unstructured guess-and-check loop converges fast because there's really only one plausible explanation.\n\nFor hard bugs, the unstructured loop is catastrophic. The hypothesis space is large, and most guesses are wrong. Without explicit enumeration and falsification, the team chases the same wrong hypothesis for days, each test giving ambiguous results that get interpreted as supporting whichever hypothesis the team currently prefers.\n\nThe discipline of writing hypotheses down and designing falsifiable tests is what prevents this. It's slow to start and fast to finish.\n\n## How AI assistance amplifies the method\n\nReloadium Edge Case Debugger is structured around exactly this discipline. The generated output is not a single answer — it's an enumerated list of hypotheses, each with a designed verification step, ordered roughly by cost. The team's job becomes running the tests and updating the hypothesis list as evidence comes in.\n\nThis amplifies what senior engineers already do and makes the method accessible to engineers who haven't internalized it yet. The biggest gain is in the enumeration step: the AI surfaces hypothesis categories the team hadn't thought of, which is the failure mode that turns a half-day bug hunt into a week-long slog.",{"title":21,"summary":22,"body":23},"Débogage piloté par hypothèses — la discipline qui sépare les ingénieurs seniors du reste","La plupart du débogage est du pattern matching non structuré contre l'expérience personnelle. Le débogage piloté par hypothèses remplace ça par une méthode explicite — et la différence de vitesse se compose dramatiquement sur les bugs difficiles.","## Ce que veut dire le débogage piloté par hypothèses\n\nObservez un junior et un senior déboguer le même problème : la différence n'est pas dans les outils ou la connaissance du code. C'est dans la *méthode*.\n\nUn junior : lit l'erreur, devine une cause, change quelque chose, relance, ajuste. La boucle est rapide mais non structurée.\n\nUn senior forme une liste explicite d'hypothèses plausibles, puis conçoit un test spécifique pour chacune qui pourrait l'*éliminer*. Il les exécute par ordre de coût.\n\n## Les cinq principes\n\n**1. Séparer symptômes et hypothèses.** Le symptôme est ce que vous observez. L'hypothèse est une explication candidate.\n\n**2. Énumérer avant de tester.** L'hypothèse devinée en premier est rarement la bonne.\n\n**3. Concevoir des tests qui falsifient, pas qui confirment.** Un test de confirmation est une preuve faible. Un test de falsification élimine proprement.\n\n**4. Les tests les moins chers d'abord.** Vous éliminerez souvent trois hypothèses pour le coût d'en tester une.\n\n**5. S'arrêter quand une hypothèse explique tout.** \"Le réparer\" avant ce point, c'est livrer le mauvais correctif.\n\n## Pourquoi ça compte plus pour les bugs difficiles\n\nPour les bugs faciles, c'est overkill. Pour les bugs difficiles, la boucle non structurée est catastrophique : l'espace d'hypothèses est large, la plupart des devinettes sont fausses, et sans falsification explicite l'équipe poursuit la même mauvaise hypothèse pendant des jours.\n\n## Comment l'assistance IA amplifie la méthode\n\nReloadium Edge Case Debugger est structuré autour de cette discipline.
