+## Fee model final DBC
+
+```text
+k_sol_fee_events meteora_dbc        = 89 parents
+k_sol_fee_event_amounts meteora_dbc = 96 legs
+parent scalar without leg           = empty
+orphan fee amount legs              = empty
+allowlisted recovery on DBC          = empty by design
+```
+
+## Cross-base fee recovery checks
+
+| Base | Result |
+|---|---|
+| `meteora_dbc` | stable, no regression, 89/96 fee parent/legs. |
+| `raydium_launchpad` | allowlisted CPI recovery enriched all observed claim/collect fee parents in tested corpus. |
+| `raydium_cpmm` | creator fee recovered; fund/protocol fee explicit no-transfer in tested corpus. |
+| `pump_swap` | coin creator fee mostly recovered; zero/no-transfer cases explicit. |
+| `pump_fees` | donation and sweep buyback recovered when CPI SPL transfers are present. |
+
+## Closure decision
+
+`0.7.56 meteora_dbc` is closed. Next tranche: `0.7.57 meteora_dlmm` full decode + full materialization.
