fix(dl,#12992): retirer le doublon orphelin 3.1-Retropropagation-From-Scratch.ipynb by myia-po-2023 · Pull Request #12996 · jsboige/CoursIA

myia-po-2023 · 2026-08-25T18:19:57Z

Grain: CLEAN/depot — lane myia-po-2023:CoursIA-2 — prev: DEEP/notebook-dl #12995

Summary

Suppression du doublon orphelin MyIA.AI.Notebooks/ML/DataScienceWithAgents/03-DeepLearning/3.1-Retropropagation-From-Scratch.ipynb.

Provenance (audit §E pendant la PR #12995) : deux notebooks 3.1 coexistent sur main —
From-Scratch (livré par #12468) et Retropropagation (livré par #12736, fresh rebase des
mêmes issues #12407/#12408). La PR #12736 a livré la version renommée sans retirer l'ancienne.

Vérifications :

0 référence entrante dans tout le dépôt (grep md/ipynb/json/yml + scripts/ + .github/ + docs/) — la seule occurrence est le fichier lui-même.
Absent du README série et du README parent : aucun lien à retoucher.
COURSE_CATALOG.generated.json : 0 mention → suppression sans churn catalogue (catalogue intact).

Aucun changement de navigation, de README ni de catalogue.

Closes #12992

…-Scratch.ipynb (superséde #12736) Audit §E : deux notebooks 3.1 coexistent sur main — From-Scratch (livré #12468) et Retropropagation (livré #12736, fresh rebase du même #12407/#12408). Le From-Scratch est orphelin : 0 référence entrante (grep md/ipynb/json/yml + scripts/.github/docs), absent de tous les READMEs et du COURSE_CATALOG. Suppression sans ajustement de navigation ni de catalogue. Co-Authored-By: Claude-Code <noreply@anthropic.com>

→ WITHDRAW — cette PR serait une régression de contenu ; #12760 la fait correctement

Relu à froid (clone-sweep + anti-régression), cette PR supprime le seul exemplaire du Capstone Jacobiennes + des Références :

Orphelin 3.1-Retropropagation-From-Scratch.ipynb (main) : 15 occurrences capstone/jacob/Rumelhart/Glorot — il porte la section « Capstone : la backward comme composition de Jacobiennes », les Références (Rumelhart 1986, Glorot & Bengio 2010, Nielsen, Baydin 2018) et l'Exercice 3 capstone.
Canonique 3.1-Retropropagation.ipynb (main ET branche) : 0 occurrence — il ne les a pas.
Diff de cette PR : uniquement l'orphelin supprimé, canonical non modifié.

Donc le diff perd le Capstone Jacobiennes + Références sans les absorber — exactement l'anti-pattern de anti-regression (« cellule # Solution / # Exemple résolu supprimée = régression INTERDITE »), et le point précis documenté par #12753.

#12760 (po-2024, fix/12753-dl31-reconcile) fait la bonne chose : absorbe d'abord le Capstone Jacobiennes + Références + Exercice 3 dans le canonique, puis supprime l'orphelin dans le même commit (Consolider != Archiver). Je retire cette PR en sa faveur — la réconciliation #12753/#12992 appartient à la lane qui a écrit les deux notebooks (po-2024).

Je referme #12996 (redundante + regression). #12992 sera résolue par le merge de #12760.

G-VAR-2/3 GENRE signals (advisory, non bloquant, #10020).
La lane `myia-po-2023:CoursIA-2` voit ces signaux actifs sur les mergees du jour (UTC 2026-08-26) :

GENRE-UNKNOWN : le genre canonise `depot` est hors enumeration close -- trou d'adjacence G-VAR-3, requalifier le genre dans le body (Un genre hors énumération passe silencieusement : canonicalize_genre le rend tel quel, aucun signal, adjacence G-VAR-3 inatteignable #12158)

G-VAR-2 plafonne a max(1, grains_mergees_du_jour // 3) LIGHT par lane et par jour, toutes categories LIGHT confondues -- un RATIO, pas un plafond plat ; le cap calcule du jour est dans le tally ci-dessus. G-VAR-3 interdit deux genres LIGHT consecutifs. Les signaux ci-dessus rendent le fait VISIBLE (labels variation-tier-inflation, `variation-genre-run`, `variation-genre-cap-exceeded`, `variation-genre-mismatch`, `variation-genre-unknown`) -- la decision de merge reste au coordinateur.
