📊 Code Quality Score: 5/100

20 (base) × 0.25 (Micro ESF) = 5.0

Category	Score	Factors
🔭 Scope	5/20	5 files touched across preprod and prod environments; version bumps across multiple container types; promotion tracking files updated
🏗️ Architecture	2/20	No architectural changes; purely version/config value substitutions; session-id file addition has no architectural significance
⚙️ Implementation	2/20	Simple value replacements in YAML/text files; no logic, algorithms, or code patterns; auto-generated JSON file
⚠️ Risk	8/20	50% reduction in prod web replicas (12→6) is significant operational risk with no justification; large version jump (7 minor versions) without changelog; mixed prod and preprod changes in single PR
✅ Quality	2/15	No tests applicable for infra changes; no PR description explaining changes; no justification for prod replica reduction; no rollback plan documented
🔒 Perf / Security	1/5	Replica reduction has performance/availability implications but no capacity analysis or load testing evidence provided
