 ## État final validé `0.7.56` — `meteora_dbc` + socle `fee_event_amounts`
 La tranche `0.7.56 meteora_dbc` est clôturée côté decoder local maximal, coverage, tests synthétiques, matérialisation prudente et validation SQL sur base dédiée. Le programme traité est :
 ```text
 dbcij3LWUppWqq96dh6gJWwBifmcGfLSB5D4DuSMaqN
 ```
 Source IDL locale prioritaire :
 ```text
 idls/meteora_dbc.dbcij3LWUppWqq96dh6gJWwBifmcGfLSB5D4DuSMaqN.json
 ```
 Surface couverte : `28` instructions, `23` events Anchor, `9` accounts et `59` types. Les instructions `swap` et `swap2` sont les seules candidates trade/candle directes, uniquement lorsque les montants et les mints base/quote sont fiables. Les initialisations de virtual pool, migrations, lockers, metadata/config/operator et transferts de créateur alimentent les tables non-trade adaptées ou restent decoded-only avec raison explicite. Les transactions failed restent audit-only.
 Validation locale finale rapportée :
 ```text
 cargo test -p kb_lib -> 446 passed / 0 failed

 Total meteora_dbc                 89 fee parents / 96 amount legs
 ```
 La tranche introduit le socle générique `k_sol_fee_event_amounts` :
 - `k_sol_fee_events` reste l'événement fee parent ;
 - `k_sol_fee_event_amounts` stocke les legs de montants, avec `fee_event_id`, `leg_index`, `token_mint`, `amount_raw`, comptes source/destination et `amount_source` ;
 - tout parent fee avec `fee_token_mint + fee_amount_raw` crée automatiquement un leg scalaire ;
 - les fees multi-mint/multi-leg laissent le parent sans montant scalaire et stockent les montants fiables dans les legs ;
 - une recovery `allowlisted_inner_spl_transfer` existe pour les anciens DEX validés, mais aucun futur décodeur ne l'hérite par défaut ;
 - tout futur décodeur doit déclarer explicitement sa policy de récupération des montants fee.
 Checks de fermeture `0.7.56` :
 - fallback `upstream_git` `meteora_dbc` pour entrées couvertes localement : vide ;
 - decoded `meteora_dbc` sans coverage : vide ;
 - successful non-materialized sans `skip*Reason` ou policy explicite : vide ;
 - failed transaction avec business materialization : vide ;
 - multi-target materialization : vide ;
 - non-swap vers trade/candle : vide ;
 - parent fee avec `fee_token_mint + fee_amount_raw` mais sans `k_sol_fee_event_amounts` : vide ;
 - legs fee orphelins : vide ;
 - recovery générique `allowlisted_inner_spl_transfer` non appliquée à `meteora_dbc`, qui reste couvert par ses chemins spécifiques.
 Contrôles croisés réalisés sur anciennes bases : `raydium_launchpad`, `raydium_cpmm`, `pump_swap`, `pump_fees`, `pump_fun`, `raydium_amm_v4`, `raydium_clmm`, `raydium_stable_swap`. Les parents fees scalaires ont des legs ; les events sans transfert exploitable restent documentés par `fee_instruction_has_no_actual_transfer` ou `fee_instruction_has_only_zero_amount_transfers`.

 - La recovery par CPI SPL inner transfer n'est pas globale : chaque futur décodeur doit déclarer explicitement sa policy et ses event kinds autorisés.
 - Les `amount_source` connus à préserver : `parent_fee_event_amount`, `fee_event_amounts`, `inner_spl_transfer`, `lamport_balance_delta`, `allowlisted_inner_spl_transfer`.
 - Les cas sans transfert exploitable doivent écrire une raison explicite : `fee_instruction_has_no_actual_transfer` ou `fee_instruction_has_only_zero_amount_transfers`.

 # Database Event Model Review — `khadhroony-bobobot` `0.7.47-1FE5`
 ## Note `0.7.56` — modèle fee parent + amount legs
 `0.7.56` ajoute `k_sol_fee_event_amounts` comme table enfant de `k_sol_fee_events`. Cette table est obligatoire dès qu'un event fee porte plusieurs montants, plusieurs mints ou plusieurs destinations. Le parent `k_sol_fee_events` reste l'ancre logique liée au `decoded_event_id`; les legs portent `leg_index`, `token_mint`, `amount_raw`, comptes source/destination et `amount_source`.
 Invariants :
 - tout parent fee avec `fee_token_mint + fee_amount_raw` doit avoir un leg scalaire automatique ;
 - un fee multi-leg/multi-mint ne doit pas agréger artificiellement le parent ;
 - les replays doivent supprimer/remplacer les legs avec le parent ;
 - les transactions failed restent audit-only ;
 - la recovery `allowlisted_inner_spl_transfer` est strictement allowlistée et ne s'applique pas par défaut aux futurs decoders.
 Le contrôle standard `parent scalar without leg` doit être vide sur toute base de validation. Voir `docs/reports/FEE_EVENT_AMOUNTS_MODEL_NOTE_0_7_56.md`.
 ## Conclusion courte
 La base actuelle est **suffisante pour continuer le décodage exhaustif en audit-only**, parce que `k_sol_dex_decoded_events` garde les events décodés avec `payload_json`.

 ## 1. Archive et fichiers à fournir
 Utiliser l'archive la plus récente après application des docs `0.7.56 final`.
 Fichiers à lire en priorité :
 - `README.md` ;
 - `ROADMAP.md` ;
 - `CHANGELOG.md` ;

 - `kb_lib/src/non_trade_event_materialization.rs` ;
 - `kb_lib/src/db/queries/fee_event_amount.rs`.
 Ne pas supposer que l'ancien support `0.7.45 meteora_dlmm` est suffisant : il était partiel. `0.7.57` doit viser la parité IDL/corpus complète.
 ## 2. État validé avant cette version
 `0.7.56 meteora_dbc` est clos.
 Build final :

 parent scalar without leg           = empty
 orphan fee amount legs              = empty
 ```
 Règles fee à préserver :
 - parent fee scalaire -> leg `k_sol_fee_event_amounts` automatique ;
 - fee multi-leg/multi-mint -> parent sans agrégation artificielle, legs explicites ;
 - pas de montant depuis `maxAmount`, `u64::MAX`, bornes ou limites de claim ;
 - recovery CPI SPL générique uniquement si policy/allowlist explicite ;
 - aucun futur decoder ne doit hériter de `allowlisted_inner_spl_transfer` par défaut.
 ## 3. Objectif de `0.7.57 meteora_dlmm`
 Program id cible :
 ```text
 LBUZKhRxPF3XUpBCjp4YzTKgLccjZhTSDM9YuVaPwxo
 ```
 IDL locale prioritaire :
 ```text
 idls/meteora_dlmm.LBUZKhRxPF3XUpBCjp4YzTKgLccjZhTSDM9YuVaPwxo.json
 ```
 Nom IDL : `lb_clmm`.
 Surface IDL :
 ```text
 76 instructions
 30 events Anchor
 12 accounts
 ```
 Objectif : **full decode + full materialization**.
 Règle forte :
 > Tout ce qui peut être décodé doit être décodé. Tout ce qui peut être matérialisé de façon fiable doit être matérialisé. Ce qui ne peut pas être matérialisé doit rester decoded-only/audit-only avec `skip*Reason` explicite. les instructions/events/anchors/discriminator non observés aprés backfill sur une base de donnée vierge devront avoir des tests syntetiques.
 ## 4. Méthode obligatoire
 Créer une nouvelle DB dédiée à `0.7.57 meteora_dlmm`.
 Après chaque backfill ou patch decoder :
 ```text
 skipDexDecode=no
 forceDexDecode=yes
 deferInstructionObservations=yes
 ```
 Puis : refresh catalog, replay local, SQL validation, note des compteurs.
 Ne pas rouvrir `meteora_dbc`, Pump ou Raydium sauf bug prouvé par SQL.
 ## 5. Sources à comparer
 Comparer au minimum :
 - IDL locale `idls/meteora_dlmm.LBUZKhRxPF3XUpBCjp4YzTKgLccjZhTSDM9YuVaPwxo.json` ;
 - Carbon Meteora DLMM decoder ;
 - Pinax/Substreams Solana IDLs ;
 - Solana Streamer / sol-parser-sdk si DLMM y apparaît ;
 - code local historique `kb_lib/src/dex/meteora_dlmm.rs` ;
 - coverage existante `k_sol_dex_event_coverage_entries` ;
 - corpus SQLite neuf ;
 - anciens rapports `0.7.45` et matrices pour comprendre ce qui était déjà validé.

 ## 9. SQL de validation attendu
 Créer/mettre à jour :
 ```text
 validation_sql/SQL_VALIDATION_METEORA_DLMM_0_7_57.sql
 ```
 Le fichier doit vérifier au minimum :

 2. instruction observations DLMM ;
 3. coverage DLMM ;
 4. decoded DLMM sans coverage ;
 5. successful non-materialized sans skip reason ;
 6. failed tx materialization ;

 9. fee parent/legs ;
 10. orphan fee legs ;
 11. reward/fee separation ;
 12. orderbook/limit-order sans double-count ;
 13. watchlist globale.
 ## 10. Invariants de fermeture
 `0.7.57 meteora_dlmm` ne peut être clôturé que si :
 - les `76` instructions et `30` events Anchor IDL sont dans la coverage ou explicitement non observés avec tests synthétiques ;
 - aucun fallback upstream DLMM ne reste pour les entrées couvertes localement ;
 - aucun decoded DLMM local sans coverage ;
 - aucune tx failed n'alimente une table métier ;
 - aucun event multi-target incohérent ;
 - aucune ligne successful non-materialized sans `skip*Reason` ou policy explicite ;
 - aucun non-swap ne produit trade/candle ;
 - aucun fee parent scalaire sans leg ;
 - aucun leg fee orphelin ;
 - aucun reward n'est classé fee par défaut ;
 - aucun limit/order event ne produit une candle sans fill exact ;
 - la watchlist globale ne contient plus de backlog dominant `meteora_dlmm`.
 ## 11. Contraintes de code à respecter
 - Rust 2024 ;
 - async-first ;
 - tracing obligatoire ;
 - pas de `?`, pas de `unwrap/expect` en production ;
 - pas de `anyhow` / `thiserror` ;
 - pas de `mod.rs` ;

 - pas de macro DB/coverage ;
 - après modification DB : re-exports `kb_lib/src/db.rs` et `kb_lib/src/lib.rs` ;
 - après modification decoder : vérifier `kb_lib/src/dex.rs`, `kb_lib/src/lib.rs`, coverage et tests synthétiques.
 ## 12. Format de livraison attendu
 Livrer des deltas successifs :

 # Note technique — `k_sol_fee_event_amounts` et policy fees — `0.7.56`
 ## Objectif
 La table `k_sol_fee_events` était suffisante pour un fee mono-montant, mais insuffisante pour les cas multi-mint, multi-destination ou multi-composant. `0.7.56` ajoute donc `k_sol_fee_event_amounts` comme table de legs rattachée au parent fee.
 ## Modèle
 ```text
 k_sol_fee_events
  id
  transaction_id
  decoded_event_id
  fee_token_mint      nullable / vide si multi-leg
  fee_amount_raw      nullable / vide si multi-leg
  payload_json
 k_sol_fee_event_amounts
  id
  fee_event_id
  transaction_id
  decoded_event_id
  leg_index
  fee_component_kind
  token_mint
  amount_raw
  source_account
  destination_account
  amount_source
  payload_json
 ```
 ## Règles invariantes
 1. Un parent fee scalaire avec `fee_token_mint + fee_amount_raw` doit toujours avoir un leg `0`.
 2. Un parent multi-leg ou multi-mint ne doit pas agréger artificiellement ses montants dans le parent.
 3. Les legs doivent pointer vers le même `transaction_id` et `decoded_event_id` que le parent.
 4. Les legs doivent être supprimés/remplacés lors du replay/cleanup parent.
 5. Les transactions failed ne doivent pas créer de parent ou leg fee métier.
 6. Les bornes d'instruction (`maxAmount`, `minAmount`, `u64::MAX`) ne sont pas des montants exécutés.
 ## Sources de montant acceptées
 | `amount_source` | Usage |
 |---|---|
 | `parent_fee_event_amount` | Leg généré automatiquement depuis un parent scalaire déjà fiable. |
 | `fee_event_amounts` | Source explicite reconstruite par un matérialisateur spécialisé. |
 | `inner_spl_transfer` | CPI SPL vérifié dans un matérialisateur spécialisé. |
 | `lamport_balance_delta` | Delta lamports prouvé et contextualisé. |
 | `allowlisted_inner_spl_transfer` | Recovery générique mais strictement allowlistée pour event kinds déjà validés. |
 ## Recovery allowlistée
 La recovery `allowlisted_inner_spl_transfer` n'est pas une règle globale. Elle s'applique seulement aux event kinds explicitement autorisés dans le code. Cette restriction protège les futurs décodeurs : une nouvelle surface ne doit jamais créer des legs fee à partir de transferts internes tant que la sémantique n'a pas été inspectée.
 Résultats de validation croisée en `0.7.56` :
 | Base / surface | Effet observé |
 |---|---|
 | `meteora_dbc` | Aucun usage de l'allowlist générique ; chemins spécialisés DBC conservés. |
 | `raydium_launchpad` | `212` parents enrichis en legs : `claim_creator_fee`, `claim_platform_fee`, `claim_platform_fee_from_vault`, `collect_fee`. |
 | `raydium_cpmm` | `collect_creator_fee` enrichi ; `collect_fund_fee` / `collect_protocol_fee` explicités sans transfert exploitable. |
 | `pump_swap` | `collect_coin_creator_fee` et un `transfer_creator_fees_to_pump_v2` enrichis ; autres cas zero/no-transfer explicités. |
 | `pump_fees` | `crank_donation_fee_pda` et `sweep_buyback` enrichis ; events déjà scalaires conservés. |
 ## Contrôles SQL obligatoires
 ### Parent scalaire sans leg

    ON fee.id = fea.fee_event_id
 WHERE fee.id IS NULL;
 ```
 Attendu : vide.
 ### Résumé parent/legs par event
 ```sql
 SELECT
    de.protocol_name,
    de.event_kind,
    COUNT(DISTINCT fee.id) AS fee_parent_count,
    COUNT(DISTINCT CASE
        WHEN COALESCE(TRIM(fee.fee_token_mint), '') <> ''
         AND COALESCE(TRIM(fee.fee_amount_raw), '') <> ''
        THEN fee.id
        ELSE NULL
    END) AS parent_with_scalar_amount_count,
    COUNT(DISTINCT fea.id) AS fee_amount_leg_count,
    MIN(tx.signature) AS sample_signature

 GROUP BY
    de.protocol_name,
    de.event_kind
 ORDER BY
    de.protocol_name,
    de.event_kind;
 ```
 ## Règles pour `0.7.57 meteora_dlmm`
 - Les instructions `claim_fee`, `claim_fee2`, `withdraw_protocol_fee`, `zap_protocol_fee`, `CompositionFee`, `ClaimFee`, `ClaimFee2` doivent utiliser `k_sol_fee_event_amounts` dès qu'un montant/mint fiable est disponible.
 - Les rewards (`claim_reward*`, `fund_reward`, `withdraw_ineligible_reward`) vont vers `k_sol_reward_events`, pas vers fees, sauf sémantique contraire prouvée.
 - Les `composition_fee` de swap/liquidity ne doivent pas être double-comptés si déjà inclus dans le trade/liquidity effectif.
 - Toute recovery générique doit être déclarée par policy explicite et tests synthétiques ; ne pas ajouter DLMM à l'allowlist sans audit par event kind.

 ## Décisions métier verrouillées
 ### Swaps
 - `meteora_dbc.swap` et `meteora_dbc.swap2` sont les seules entrées candidates trade/candle directes.
 - Les trades/candles ne sont produits que si les montants exécutés et les mints base/quote sont fiables.
 - Les montants de `swap2` doivent être dérivés du layout et/ou des CPI SPL effectifs ; ne pas utiliser naïvement les bornes d'instruction.
 - Les events Anchor `EvtSwap` / `EvtSwap2` restent decoded-only s'ils ne portent pas un contexte mint/pair suffisant ou s'ils doublonnent l'instruction matérialisée.
 ### Lifecycle / migration / lockers
 - `initialize_virtual_pool_with_spl_token` et `initialize_virtual_pool_with_token2022` alimentent lifecycle/catalog lorsque les comptes pool/base/quote/config sont fiables.
 - `create_locker`, `migrate_meteora_damm_claim_lp_token`, `migrate_meteora_damm_lock_lp_token`, `migration_damm_v2*` et `migrate_meteora_damm*` sont lifecycle, pas liquidity artificielle.
 - Les metadata-only restent decoded-only avec raison explicite si elles n'apportent pas de cible métier fiable.
 ### Admin/config
 - `create_config`, `create_operator_account`, `close_*operator*`, metadata, `transfer_pool_creator` et events config/admin alimentent `k_sol_pool_admin_events` uniquement si l'acteur et la cible sont fiables.
 - Les payloads génériques ou incomplets restent audit/decoded-only.
 ### Fees
 - Les fees DBC utilisent le modèle parent+legs : `k_sol_fee_events` + `k_sol_fee_event_amounts`.
 - Les maxima d'instruction (`maxAmount*`, `u64::MAX`, bornes de claim) ne sont pas des montants exécutés.
 - Les montants fiables proviennent des CPI SPL, des legs explicitement reconstruits ou des lamport balance deltas prouvés.
 - Les events Anchor fee sans mint restent decoded-only avec `skipFeeReason`.
 - Les cas sans transfert réel portent `fee_instruction_has_no_actual_transfer` ou `fee_instruction_has_only_zero_amount_transfers`.
 ## Matérialisation fee finale
 | Event kind | Fee parents | Parents scalaires | Amount legs | Décision |
 |---|---:|---:|---:|---|
 | `meteora_dbc.claim_creator_trading_fee` | 8 | 8 | 8 | Mono-leg fiable. |
 | `meteora_dbc.claim_partner_pool_creation_fee` | 10 | 10 | 10 | Mono-leg fiable. |
 | `meteora_dbc.claim_protocol_fee` | 10 | 10 | 10 | Mono-leg fiable. |
 | `meteora_dbc.claim_protocol_pool_creation_fee` | 10 | 10 | 10 | Mono-leg/lamport delta fiable. |
 | `meteora_dbc.claim_trading_fee` | 11 | 6 | 18 | Mix mono-leg et multi-leg ; parent non agrégé pour multi-leg. |
 | `meteora_dbc.creator_withdraw_surplus` | 2 | 2 | 2 | Mono-leg fiable ; résiduels sans transfert réel explicités. |
 | `meteora_dbc.partner_withdraw_surplus` | 9 | 9 | 9 | Mono-leg fiable. |
 | `meteora_dbc.withdraw_leftover` | 10 | 10 | 10 | Mono-leg fiable. |
 | `meteora_dbc.withdraw_migration_fee` | 9 | 9 | 9 | Fee, pas migration target ; mono-leg fiable. |
 | `meteora_dbc.zap_protocol_fee` | 10 | 10 | 10 | Mono-leg fiable. |
 | **Total `meteora_dbc`** | **89** | n/a | **96** | Parent+legs validé. |
 ## Socle `k_sol_fee_event_amounts`
 La version `0.7.56` ajoute un modèle durable pour les fees composés :
 - `k_sol_fee_events` est le parent logique unique lié au `decoded_event_id` ;
 - `k_sol_fee_event_amounts` contient les legs de montants, avec `leg_index`, `fee_component_kind`, `token_mint`, `amount_raw`, comptes source/destination et `amount_source` ;
 - un parent avec `fee_token_mint + fee_amount_raw` crée automatiquement un leg scalaire ;
 - un parent multi-leg/multi-mint laisse les champs scalaires du parent vides et stocke tout dans les legs ;
 - les deletes/replays nettoient les legs avant ou avec le parent ;
 - la requête de contrôle `parent scalar without leg` doit rester vide.
 Sources `amount_source` connues en fin de tranche :
 ```text
 parent_fee_event_amount
 fee_event_amounts
 inner_spl_transfer
 lamport_balance_delta
 allowlisted_inner_spl_transfer
 ```
 ## Recovery fee allowlistée
 La recovery `allowlisted_inner_spl_transfer` est volontairement non globale.
 Elle a été testée sur anciennes bases pour enrichir les surfaces déjà connues :
 | Surface testée | Résultat |
 |---|---|
 | `raydium_launchpad` | `claim_creator_fee`, `claim_platform_fee`, `claim_platform_fee_from_vault`, `collect_fee` enrichis en legs depuis CPI SPL. |
 | `raydium_cpmm` | `collect_creator_fee` enrichi ; `collect_fund_fee` et `collect_protocol_fee` restent sans transfert réel exploitable dans le corpus testé. |
 | `pump_swap` | `collect_coin_creator_fee` et certains `transfer_creator_fees_to_pump_v2` enrichis ; cas zero/no-transfer explicités. |
 | `pump_fees` | `crank_donation_fee_pda` et `sweep_buyback` enrichis ; events déjà scalaires conservés. |
 | `meteora_dbc` | Non concerné par l'allowlist générique ; DBC conserve ses chemins spécifiques. |
 Règle pour les prochaines versions : tout nouveau decoder doit déclarer explicitement sa policy de récupération des montants fee. Aucun futur decoder ne doit hériter automatiquement de la recovery CPI SPL.
 ## Checks de fermeture
 Les contrôles de fermeture exigés sont propres :
 - fallback `upstream_git` `meteora_dbc` pour entrées couvertes localement : vide ;
 - decoded `meteora_dbc` sans coverage : vide ;
 - successful non-materialized sans `skip*Reason` ou policy explicite : vide ;
 - failed tx avec materialization métier : vide ;
 - multi-target materialization : vide ;
 - non-swap DBC vers trade/candle : vide ;
 - parent fee scalaire sans leg : vide ;
 - legs fee orphelins : vide ;
 - watchlist globale sans backlog dominant `meteora_dbc`.
