 1. Read this WorkUnit's section at the end of the user prompt. It lists your `rawFiles`, any unchanged `dependencyPaths` you may need to resolve references, the `peerFileIndex` (paths only; you CANNOT read them), the source's `skillNames`, and any `priorProvenance` rows telling you what earlier syncs produced from these files.

 3. If the system prompt includes `<canonical_pins>`, read those pins before choosing artifact keys. A pin's `canonicalArtifactKey` is the preferred artifact for its `contestedKey`: prefer editing the pinned canonical artifact when it already exists or when this raw file clearly updates it. Do not create a duplicate contested artifact when a pin says another artifact is canonical; use a specific disambiguated key only when the raw file describes a genuinely different domain.
-4. For each raw file: call `read_raw_file` (or `read_raw_span` for slicing large files) to load content. Before writing a new SL source or wiki page, call `discover_data` for each candidate source, table, metric, or topic name to find prior-WU writes, existing wiki pages, SL sources, and raw warehouse matches; apply `ingest_triage` when you hit one, and apply any matching canonical pin before deciding whether to edit, rename, or skip.

 5. For every `wiki_write`, `wiki_remove`, `sl_write_source`, or `sl_edit_source` call, include `rawPaths` with only the raw file paths that directly support that action. If one artifact synthesizes several files, list each contributing raw file. Do not include unrelated files from the same WorkUnit.
 6. When `priorProvenance` names an existing artifact for one of your raw files, prefer `sl_edit` over `sl_write` for that artifact: the re-ingest change rule says expression-only changes replace silently, grain/column/filter changes replace and flag.
 7. When a raw file cannot map to normal SL and you use a fallback path, call `emit_unmapped_fallback` exactly once for that raw file and reason. Use `fallback: "sql_standalone"` for a standalone SQL source, `fallback: "wiki_only"` for documentation-only capture, and `fallback: "flagged"` when no reliable artifact can be written.

 - Do not invent physical column names or grain keys. For table-backed SL sources, every `columns:`, `grain:`, `joins:`, `segments:`, and `measures[].expr` column must come from raw-file column declarations or warehouse-backed discovery (`discover_data`, `sl_discover`, `entity_details`). If column names are not confirmed, capture the business context in wiki instead of writing a full SL source.
 - Do not write context-source overlays into the context source connection just because that is the current WorkUnit connection. Use `sl_discover` across data sources and write the SL artifact to the warehouse/data-source connection that owns the matching manifest. If there is no confirmed target connection, use `emit_unmapped_fallback` and wiki capture.
 - Do not duplicate an artifact that prior provenance says you already produced; update it.
