 15. **Bundler3 swap route integrity**: Bundler3 swap leverage/deleverage must use adapter flashloan callbacks (not pre-swap borrow gating), with `callbackHash`/`reenter` wiring and adapter token flows matching on-chain contracts; before submit, verify aggregator quote/tx parity (trusted target, exact/min calldata offsets, and same-pair combined-sell normalization) so previewed borrow/repay/collateral amounts cannot drift from executed inputs; prefer exact-in close executors that fully consume the withdrawn collateral over max-sell refund paths that can strand shared-adapter balances, and only relax build-time allowance checks for adapter-executed paths when the failure is allowance-specific.
 16. **Quote, preview, and route-state integrity**: when a preview depends on one or more aggregator legs, surface failures from every required leg and use conservative fallbacks (`0`, disable submit) instead of optimistic defaults, but optional exact-close quote legs must not block still-valid partial execution paths; if a close-out path depends on a dedicated debt-close bound (for example BUY/max-close quoting) plus a separate execution preview, full-close / repay-by-shares intent must be driven by one explicit close-route flag shared by preview and tx building, the close executor must be satisfiable under the same slippage floor shown in UI, and if the current sell quote can fully close debt while the exact close bound is still unresolved the UI must fail closed rather than silently degrading to a dust-leaving partial path; for exact-in swap deleverage routes, the exact close bound is a threshold for switching into close mode, not a universal input cap, so valid oversell/refund paths must remain available and previews must continue to match the selected exact-in amount; preview rate/slippage must come from the executable quote/config, selected route mode must never execute a different route while capability probes are in-flight, and route controls/entry CTAs must stay consistent with capability probes without duplicate low-signal UI.
 17. **Permit2 time-units and adapter balance hygiene**: Permit2 `expiration`/`sigDeadline` values must always be unix seconds (never milliseconds), and every adapter-executed swap leg must sweep leftover source tokens from the adapter before bundle exit so shared-adapter balances cannot accumulate between transactions.
+18. **Smart-rebalance constraint integrity**: treat user max-allocation limits (especially `0%`) as hard constraints in planner output and previews, not soft objective hints; when liquidity/capacity permits, planner targets must not leave avoidable residual allocation above cap, and full-exit targets must use tx-construction-compatible withdrawal semantics so previewed and executed allocations stay aligned.
+19. **Monotonic transaction-step updates**: never call `tracking.update(...)` unconditionally in tx hooks; compute step order for the active flow and only advance when the target step is strictly later than the current runtime step, so auth/permit pre-satisfied states cannot regress the stepper backwards.
+20. **Share-based full-exit withdrawals**: when a rebalance target leaves only dust in a source market, tx builders must switch to share-based `morphoWithdraw` (full shares burn with expected-assets guard) instead of asset-amount withdraws, so "empty market" intent cannot strand residual dust due rounding.
