# Discovery Log

Record *how a paper was discovered* — the optional `discovery:` block in a
citation sidecar's frontmatter (SOURCE-TRACKING schema). The read views
`by-source` / `by-curator` (#1492) consume this.

## How to run

```bash
aiwg corpus discovery-log --ref REF-640 --surface x-account --via "x.com/@askalphaxiv" --curator PROF-S-askalphaxiv          # dry-run (prints the block)
aiwg corpus discovery-log --ref REF-640 --surface x-account --via "x.com/@askalphaxiv" --curator PROF-S-askalphaxiv --write  # splice into the sidecar
aiwg corpus discovery-log --ref REF-641 --surface x-search --write    # surface only, no curator
```

- Adds or **replaces** the `discovery:` block in the sidecar frontmatter,
  preserving the rest of the file. Dry-run unless `--write`.
- `--surface` (required) vocab: `x-account | x-search | x-bookmarks | x-foryou |
  x-following | rss | newsletter | web | referral | direct`.
- `--curator` (optional) is a `PROF-S-` id; set it only when the source came
  through a named, repeatable curator. Omit for `direct`/search-found papers
  (`curator-id: null`). The block is OPTIONAL by design — absence is never an error.

> Distinct from radar `sources-searched` (surfaces queried during a freshness
> refresh): `discovery` records where a paper was *originally found*.
