 ## 2026-10-20 — RE-627 Trace retry unlink stack and ten-attempt boundary (separate task commit)
 
 Each retry captures unlink−32, appends the target pointer and increments count; the tenth target exits to restoration instead of issuing another trace. 30 count/target fixtures independently check stack writes, exact retry boundary and native call ABI. Full suite: 994 tests pass. Report regenerates byte-identically (48984 bytes). Storage/filter, links and whitespace checks pass. No assets/Rust runtime/shared VM evaluator changed; native/reference/legal/full platform scope remains open.

+The skipped-target cleanup issues native−31 in insertion order and preserves duplicate entries; empty lists issue no relink request. Eight empty/reordered/duplicate/ten-entry cases independently verify pointer order, loop cursor and untouched list contents. Full suite: 997 tests pass.

+RE-628. Reproduce with `python3 scripts/analyze_qvm_trace_relink.py`; check with `python3 scripts/test_qvm_trace_relink.py`. The [machine report](qvm-trace-relink.json) retains source identity and bounded fixtures.
+
+Actual292299–292325 initializes the list cursor and issues one captured native−31 per local56+4×index entry through local52. There is no sorting, reverse traversal or deduplication. Explicit fixtures cover zero, one, reordered pairs, repeated pointers and ten entries. The source list remains intact, and the final cursor equals count. These are source call-order findings; captured native requests do not establish engine relink effects or prove repeated targets are legal live collision outcomes. Candidate bound restoration and shooter rewind restoration are later parts of291641.

+No original executable/full QVM/native collision/physics/rendering executes. Native responses and legal input domains are supplied or unverified where stated; full runtime/macOS/Linux Rust/Bevy/Solari gameplay remains open.
