+# Delta `0.3.7-pre.012` — frontend fonctionnel, summary terminal et autocomplete Program ID
+
+## 1. Base requise
+
+```text
+0.3.7-pre.011
+workspace.package.version = 0.3.7-pre.11
+```
+
+## 2. Objectif
+
+Terminer le frontend fonctionnel sans ouvrir de nouveau runtime : enrichir les feedbacks terminal/erreurs et ajouter à l'adresse un autocomplete HTML libre alimenté exclusivement par le registre canonique `ksp-core-lib::entries()`/`ProgramIdEntry`.
+
+## 3. Dataset Program ID canonique
+
+`ProgramIdAutocompleteOptionDto` projette uniquement les métadonnées publiques nécessaires à l'UX :
+
+```text
+program_id
+code
+name
+domain
+family
+protocol
+```
+
+`program_id_autocomplete_options()` parcourt directement `ksp_core_lib::entries()`. Aucune liste de Program IDs n'est copiée dans Backfill Desk ni dans le frontend.
+
+`BackfillDeskOptionsDto` transporte ce dataset sûr avec les autres options de campagne. Aucun endpoint, URL, credential, secret ou donnée Store n'est ajouté.
+
+## 4. Autocomplete libre côté HTML
+
+L'input `backfillAddress` reste un `<input type="text">` libre et référence :
+
+```text
+<datalist id="backfillProgramIds">
+```
+
+Le frontend construit chaque `<option>` avec le Program ID canonique comme `value`, un label lisible et des `data-*` sûrs (`code`, `name`, `domain`, `family`, `protocol`). Une adresse valide qui n'appartient pas au registre reste acceptée normalement par le mapping Rust existant.
+
+L'instrumentation de sélection ne journalise jamais l'adresse : seulement le code KSP éventuel et `registryMatch`. Aucun browser storage n'est introduit.
+
+## 5. Polish monitoring et erreurs
+
+La carte latest-value affiche désormais un résumé terminal explicite pour `completed`, `cancelled` ou `failed`. Les échecs Cancel et Resume sont projetés dans leurs feedbacks UI via le contrat d'erreur sûr déjà existant, sans contexte arbitraire ni payload métier.
+
+Aucun comportement Job/Store/Transport, checkpoint, Resume ou Cancel n'est modifié.
+
+## 6. Version
+
+```text
+workspace.package.version = 0.3.7-pre.12
+label = 0.3.7-pre.012
+```
+
+## 7. Fichiers ajoutés
+
+```text

+```
+
+## 8. Fichiers modifiés
+

+```
+
+## 9. Fichiers supprimés
+
+Aucun.
+
+## 10. Gate précédent acquis
+
+Le replay opérateur de `0.3.7-pre.011` est propre : audits Rust/Markdown, `cargo check --workspace`, Clippy, 50 tests unitaires Job Backfill et toutes les suites Backfill Desk passent. Le smoke Tauri confirme également la reprise in-session réelle avec nouveau JobId backend et checkpoint réémis Rust-only.
+
+## 11. Validations exécutées dans l'environnement d'assemblage
+
+```text
+python3 scripts/audit_rust_workspace_rules.py
+python3 scripts/audit_markdown_tables.py README.md RULES.md ROADMAP.md CHANGELOG.md docs prompts crates deltas/0.3.7
+```
+
+Contrôles ciblés :
+
+- dataset dérivé exclusivement de `ksp_core_lib::entries()` ;
+- aucune valeur Program ID canonique hardcodée dans HTML/TypeScript ;
+- `<datalist>` relié à un input adresse toujours libre ;
+- `data-*` limités aux métadonnées publiques du registre ;
+- aucune adresse journalisée pendant l'évaluation autocomplete ;
+- aucun `localStorage`, `sessionStorage`, IndexedDB ou cookie ajouté ;
+- summary terminal et feedbacks Cancel/Resume sûrs ;
+- aucune dépendance/feature Cargo modifiée ;
+- `std.store.json` inchangé ;
+- syntaxe TypeScript validée par transpilation locale ;
+- contrôle différentiel des headers et reconstruction stricte du delta.
+
+## 12. Validations non exécutées dans l'environnement d'assemblage
+
+`cargo` et `rustfmt` ne sont pas disponibles dans l'environnement d'assemblage. Gate opérateur obligatoire avant `pre.013` :
+
+```text
+cargo fmt --all
+python3 scripts/audit_rust_workspace_rules.py
+python3 scripts/audit_markdown_tables.py README.md RULES.md ROADMAP.md CHANGELOG.md docs prompts crates deltas/0.3.7
+cargo check --workspace
+cargo clippy --workspace --all-targets
+cargo test -p ksp-job-backfill-lib
+cargo test -p ksp-app-backfill-desk
+```
+
+Aucun `cargo tree` n'est requis : dépendances et features Cargo sont inchangées.
+
+## 13. Suite
+
+`pre.013` est réservé au hardening/completude : tests desktop/security/dependency/composition/release-completeness et canaries DTO, sans nouvelle capacité métier.
