+Recommended replay settings used:
+
+```text
+skipDexDecode=no
+forceDexDecode=yes
+deferInstructionObservations=yes
+```

+## Final SQL gates
+
+| Gate | Result |
+|---|---:|
+| Upstream fallback for local DLMM coverage | empty |
+| Local `instruction_audit` observed | `0` |
+| Decoded DLMM without coverage | empty |
+| Successful non-materialized without explicit skip/policy | empty |
+| Failed transaction business materialization | empty |
+| Multi-target materialization | empty |
+| Non-swap trade/candle safety | empty |
+| Fee parent scalar without amount leg | empty |
+| Orphan fee amount legs | empty |
+| Reward/fee collision | clean separation |
+| Limit/orderbook trade/candle double-count | empty |
+| Logical duplicate coverage rows | empty |
+
+## Final materialization counters
+
+```text
+trade events      = 106
+liquidity events  = 664
+lifecycle events  = 1107
+candles           = 424
+```
+
+## Important decisions
+
+- `swap_event` and `swap2_evt` are materialized as lifecycle `swap_log`, not as trades.
+- `initialize_preset_parameter_v2` was added from corpus evidence for discriminator `75c73e67068e1fcb`.
+- `close_bin_array` has `16` observations but only `14` materializations because `2` transactions failed with `Custom 6015`.
+- `initialize_reward` and `initialize_reward_event` remain without amounts because they are configuration/init events, not transfers.
+- No observed useful DLMM event remains decoded-only.
+
+## Closure decision
+
+`0.7.57 meteora_dlmm` is considered closed for the validated corpus. Future changes require new corpus evidence.
