 ## Summary
 
-The branch adds comment-only telemetry hook markers on the authoritative `POST …/skill-progression` path after a successful `TryApplyXpDelta`, plus a second marker on the level-up branch. Behavior and JSON contracts are unchanged; documentation (implementation plan, manual QA, E2.M2 module note, Bruno doc string) matches the comments-only kickoff decision. Server tests pass. One documentation-tracking row should be refreshed when this merges so the implementation alignment table stays consistent with `E2_M2_XpAwardAndLevelEngine.md`.

 ## Nits
 
-- **Nit:** The implementation plan’s technical approach for `level_up` mentions “deltas” in the payload sketch; the in-code comment lists `playerId`, `skillId`, `previousLevel`, `newLevel` but not XP/total deltas. Optional one-word addition (`prevXp`/`newXp` or total XP) if you want comment parity with the plan.
