## Why
When a nested code-mode call's recorded arguments were truncated and attached to an output before its result arrived, the recorder could no longer attach the result metadata to that call.
## What changed
Retain validated call bindings so late result metadata updates the original output across retries and subsequent waits. Keep truncated arguments and incomplete call inventories intact, and apply existing metadata budgets.
Invalidate late metadata bindings when duplicate IDs, reused cells, conflicting outputs, or changed call inventories make attribution ambiguous. Clear stale pending calls when a cell ID is reused, and avoid counting duplicate pending IDs against capacity more than once.
## Testing
Add recorder regression tests for late metadata across retries, compaction, waits, and cell closure, plus ambiguous bindings and budget limits. Add a code-mode integration test that delays a tool result until its truncated call has been recorded and verifies metadata remains attached to the original output across later waits.
