+```
+

+
+## Objet
+
+Figer la surface backend-neutral requise par le cycle de vie complet des variantes/conflits avant toute migration PostgreSQL V004.
+
+Cette tranche reste strictement dans `ksp-store-api` et ajoute :
+
+```text
+inspection des variantes
+inspection des conflict cases
+participant ledger DTO
+historique append-only DTO/query
+actions compare-and-set à double revision
+outcomes stale/idempotent explicites
+StoreErrorClass Transient/Terminal
+StoreErrorClassifier backend-neutral
+```
+
+Elle ne modifie encore :
+
+```text
+aucune migration SQL
+aucun backend PostgreSQL
+aucun ksp-store-lib
+aucun Worker
+aucun Transport/Config
+aucun Job Backfill
+aucune application Desk
+```
+
+## Version workspace
+
+`Cargo.toml` :
+
+```text
+header version : 652 -> 653
+workspace      : 0.3.17-pre.1 -> 0.3.17-pre.2
+```
+
+## Fichiers ajoutés

+```
+
+## Contrats variantes
+
+La lecture opérateur des variantes est portée par :
+
+```text
+RawTransactionVariantInspectionQuery
+RawTransactionVariantSummary
+RawTransactionVariantDetail
+RawTransactionVariantInspectionRead
+```
+
+La query est random-access bornée via `RawInspectionPageRequest`, exige un network et accepte seulement un filtre transaction exact cohérent avec ce network.
+
+Le summary reste payload-free et expose uniquement les métadonnées nécessaires :
+
+```text
+variant reference
+origin
+slot / block_time
+format id/version
+retention state
+payload size si disponible
+is_current_canonical
+observation_count
+created_at
+```
+
+`RawTransactionVariantDetail` peut porter la transaction RAW complète uniquement dans la lecture explicite d'un variant. Le constructeur vérifie transaction identity, slot, block time, format et taille déclarée ; un variant `Purged` ne peut pas prétendre contenir encore le payload.
+
+## Contrats conflict case
+
+Identité :
+
+```text
+RawTransactionConflictReference
+  -> RawTransactionReference
+```
+
+Inspection :
+
+```text
+RawTransactionConflictInspectionQuery
+RawTransactionConflictSummary
+RawTransactionConflictParticipantSummary
+RawTransactionConflictDetail
+RawTransactionConflictInspectionRead
+```
+
+La projection courante conserve explicitement :
+
+```text
+status Open/Resolved
+conflict revision > 0
+canonical variant
+canonical selector revision > 0
+latest incoming variant
+latest Conflict/Incomparable relation + reason
+resolved canonical variant si Resolved
+latest resolution action si Resolved
+participant_count >= 2
+created_at / updated_at
+```
+
+Les références canonical/incoming/resolved doivent appartenir à la même transaction que le conflict case.
+
+Le detail valide que le participant ledger :
+
+```text
+contient exactement participant_count entrées
+n'a aucun variant_id dupliqué
+reste dans le même scope transaction
+n'annonce aucun first_seen_revision > current conflict revision
+contient canonical/latest incoming/resolved target requis
+```
+
+## Historique append-only
+
+Types ajoutés :
+
+```text
+RawTransactionConflictEventKind
+RawTransactionConflictEventOrigin
+RawTransactionConflictEventSummary
+RawTransactionConflictHistoryQuery
+RawTransactionConflictHistoryRead
+```
+
+Event kinds figés :
+
+```text
+Opened
+ParticipantAdded
+ResolvedKeepCanonical
+ResolvedPromoteVariant
+ResolvedRestoreVariant
+Reopened
+```
+
+Origins sûres :
+
+```text
+Automatic
+Operator
+```
+
+Aucun acteur libre, texte backend, SQL ou payload RAW n'entre dans le DTO d'historique.
+
+Une transition de résolution exige exactement le `RawTransactionConflictResolutionAction` correspondant. `Opened` et `ParticipantAdded` exigent une comparaison durable `Conflict` ou `Incomparable`.
+
+## Actions compare-and-set
+
+Types :
+
+```text
+RawTransactionConflictResolutionAction
+RawTransactionConflictResolution
+RawTransactionConflictAction
+RawTransactionConflictActionRequest
+RawTransactionConflictActionOutcome
+RawTransactionConflictActionWrite
+```
+
+Actions disponibles :
+
+```text
+KeepCurrentCanonical
+PromoteVariant(target)
+RestoreVariant(target)
+Resolve(explicit canonical resolution)
+Reopen
+```
+
+Chaque request transporte obligatoirement :
+
+```text
+conflict reference
+expected_conflict_revision > 0
+expected_canonical_revision > 0
+action
+```
+
+Tout target variant doit appartenir à la transaction du conflict case.
+
+Outcomes backend-neutral :
+
+```text
+Applied
+AlreadyAtTarget
+StaleRevision
+ConflictNotOpen
+ConflictNotResolved
+VariantNotParticipant
+VariantPayloadUnavailable
+```
+
+`AlreadyAtTarget` et `StaleRevision` restent volontairement distincts : une répétition idempotente n'est pas une perte de compare-and-set concurrente.
+
+## Classification Store error
+
+`ksp-store-api` expose désormais :
+
+```text
+StoreErrorClass::Transient
+StoreErrorClass::Terminal
+StoreErrorClassifier
+```
+
+Le classifier reçoit une `ksp_core_lib::Error` déjà projetée/redacted. Le Worker futur consommera ce contrat au lieu de comparer des codes PostgreSQL ou des chaînes libres.
+
+Cette tranche ne classe encore aucun SQLSTATE concret : le raffinement physique reste réservé à `pre.006`. La politique fail-closed définie par le plan reste inchangée : tout code non explicitement reconnu par l'implémentation future sera `Terminal`.
+
+## Frontières préservées
+
+Le manifest `ksp-store-api` reste inchangé :
+
+```text
+runtime dependency exacte = ksp-core-lib uniquement
+```
+
+Aucun nouveau crate externe n'est introduit.
+
+Tous les nouveaux items publics sont réexportés depuis la racine `ksp-store-api`; aucun `pub mod` n'est ajouté. Les enums évolutifs sont `#[non_exhaustive]`.
+
+Les capabilities restent object-safe et implémentables par un backend externe sans dépendre de `ksp-store-lib` ou PostgreSQL.
+
+## Tests/canaris ajoutés ou étendus
+
+La tranche couvre statiquement et par tests Rust :
+
+```text
+network coherence des queries variant/conflict
+double revision strictement positive
+scope transaction des targets d'action
+status Open/Resolved et projection resolution cohérente
+relation conflict/incomparable requise pour le conflict current
+participant ledger complet, unique et revision-safe
+history event/action consistency
+outcomes Applied/AlreadyAtTarget/StaleRevision distincts
+codes event/origin/resolution stables
+variant detail payload debug redacted
+object safety des quatre nouvelles capabilities + classifier
+inventaire exact crate-root/module/capability
+frontière dépendances backend-neutral
+#[non_exhaustive] des nouveaux enums
+```
+
+## Validation locale de l'assemblage
+
+L'environnement d'assemblage ne fournit toujours pas `cargo`, `rustc` ou `rustfmt`. Aucun PASS Cargo n'est inventé pour `pre.002`.
+
+Audits réellement exécutés après les changements Rust :
+
+```text
+General Rust rule audit                 clean
+Rust export completeness audit          0 candidate(s)
+KSP workspace Rust rule audit           clean
+Markdown table audit                    clean (352 table(s), 966 file(s))
+```
+
+Le gate Cargo utilisateur reste autoritaire pour confirmer compilation, rustfmt, Clippy et tests.
+
+## Gate requis après application

+
+Ne pas lancer de test PostgreSQL live pour cette tranche : aucune migration ni implémentation backend n'est encore modifiée.
+
+## Prochaine tranche
+
+Après gate propre :
+
+```text
+0.3.17-pre.003
+```
+
+Objet prévu : migration PostgreSQL V004 additive pour participants, historique append-only, projection de résolution et bootstrap legacy, avec canaris garantissant l'immuabilité byte/checksum de V000/V001/V002/V003.

+
+Ce gate ferme `pre.001` et autorise `0.3.17-pre.002`. Aucun test runtime/live supplémentaire n'était requis par le delta `pre.001`.
+
+## 24. Assemblage `0.3.17-pre.002`

+```text

+append-only history DTO/query
+double-revision action request
+stale/idempotent outcomes
+StoreErrorClass + StoreErrorClassifier
+```
+
+Aucune migration V004, implémentation PostgreSQL, façade Store, politique Worker retry ou reconnexion Transport n'est introduite.
+
+Audits locaux après assemblage :
