* **New Features**
* Added configurable mapping stages for `mapping.yml`: `processing` (default) and `after_epg`.
* `after_epg` mappings now run after EPG enrichment and can react to enriched EPG fields.
* **Bug Fixes**
* Stage-aware playlist mapping: if no mappings match, the source is left unconsumed.
* Mapping directory merges now reject conflicting stages for the same mapping id and report both files clearly.
* **Documentation**
* Updated mapping DSL and target `processing_order` docs to describe stage timing and guarantees.
* **Tests**
* Added coverage for stage-restricted mapping behavior, merge conflicts, and AfterEpg timing.
