- tests/unit/test-migration-0004.php: wrap error_log() stub in function_exists() guard -- prevents PHP fatal redeclaration on PHP Lint (8.1/8.2/8.3) which runs php -l on all .php files. - tests/bootstrap.php: update wp_json_encode stub to accept int $flags = 0 second arg (matches production call signature wp_json_encode($clean, JSON_UNESCAPED_UNICODE)); guard with function_exists(). - class-pr-core-migration-0004-backfill-peptide-meta.php: add code comment near idempotency check documenting the all-or-nothing limitation (post with legitimately empty aliases will re-run). - CONVENTIONS.md: one-line note under migration conventions item 5 documenting the idempotency caveat. - CHANGELOG.md: add Fixed section under v0.6.0 for CI/test-stub fix. Agent-Session: peptide-schema-backfill v0.6.0 P1 fix
