# Which issue does this PR close? Refs #1359 (AQE epic). Documents the newly-filed limitation issues #1986, #1987, #1988, #1989. # Rationale for this change The AQE "Current limitations" list in the tuning guide described four known gaps but had no tracking issues, and pointed at the old closed issue #387 instead of the live epic #1359. Discrete issues now exist for each gap, so the docs should link to them. The contributor guide also had no material on AQE, even though it is a non-trivial part of the scheduler. # What changes are included in this PR? - **User guide (`tuning-guide.md`):** each of the four AQE limitation bullets now links to its tracking issue (#1986–#1989), and the stale #387 reference is corrected to the AQE epic #1359. - **Contributor guide (`architecture.md`):** new "Adaptive Query Execution (AQE)" section covering the static vs adaptive execution graphs, how re-optimization runs optimizer rules after each stage (and why rule idempotency matters), the optimizations implemented today (join reordering, empty-stage elimination), the code layout under `ballista/scheduler/src/state/aqe`, and the current limitations with links to the tracking issues. # Are there any user-facing changes? Documentation only. No code or API changes. -- This is an automated message from the Apache Git Service.
