# Ingest Triage - conflict classification and resolution This skill is loaded in two contexts: - By a Stage 3 WorkUnit agent when `sl_discover`, deterministic projection output, existing project memory, or prior provenance overlaps with what the current WorkUnit is about to write. - By the Stage 4 reconciliation agent for cross-WorkUnit sweeps, accepted patch overlap, and eviction decisions. Apply the rules below before every write that could collide with an existing artifact. ## Decision tree 1. **Is this the same artifact I'm producing now, or a different one with the same name?** Read both. If names match and content matches (modulo whitespace): no conflict - skip the write, the prior one stands. 2. **If content differs, is it an expression-only change (e.g. a different `sql:` body for the same measure name, same grain, same columns)?** Re-ingest change (expression-only): silently replace via `sl_edit_source`. No flag. 3. **If the difference is structural - grain, columns, filter, join shape - is the current bundle the re-ingest of a previously-ingested bundle (i.e. `priorProvenance` has a row for this raw file and artifact)?** Re-ingest change (semantic break): replace + flag. Record in the IngestReport's `conflicts_resolved` list with `flagged_for_human: true`. 4. **If reconciliation sees accepted patches from this same job with no prior-sync row, check for same-ingest contradictions:** | Kind | Detection | Resolution | |---|---|---| | Str...
