 ## 23. Validation command proof rule
 
+Before any diff, test, or compile validation, record in the same command
+transcript or final report:
+
+* `pwd` or explicit working directory
+* `git rev-parse HEAD`
+* `git status --short --branch`
+* expected PR head SHA (candidate head SHA)
+
+Validation commands must use one of:
+
+* `git -C <review_worktree> ...`
+* `cd <review_worktree> && ...` in the same command
+* tool-provided explicit working-directory metadata
+
+Do not rely on inferred shell cwd from a prior command in a different block.
+
+`gitea_validate_review_final_report` rejects validation claims without
+cwd/HEAD proof when `validation_session` is supplied.
+
+Baseline validation must document baseline worktree path, baseline target SHA,
+cwd proof, exact baseline command, and baseline result using the same rules.
+
 Report the exact validation command as executed.
 
 Report the working directory where validation ran.
