# Admission from experimental artifacts The runner never writes to `canon/` or `patterns/`. A model critique is evidence for a reviewer, not approval to promote. FEP-WP-0002-T01 owns the final metadata contract; this mapping is provisional until that task resolves the open schema issues. | Experimental representation | Repository representation | | --- | --- | | `source/source.md` plus SHA-256 and bibliography | SourceCatalog entry and source-review record | | Claim C01 scoped by workspace and source | Claim citation: review path + C01 + original locator | | Candidate P01 scoped by workspace | CandidateCatalog row; reviewed stable FEP ID only upon admission | | Candidate Definition/Solution sections | PatternSchema prose with reviewed frontmatter | | Relation proposal between local candidate IDs | Canonical typed relation between stable pattern IDs | | Generated critique pass/revise/unknown | Input to a named reviewer; not evidence maturity | For each promotion, write a review under `research/reviews/` with: - reviewer, date and whether it is a self-review; - source workspace, digests and source claim locators; - candidate IDs mapped to existing/new stable FEP IDs, with merge/split/reject reasons; - checks against the current pattern schema and at least two competing forces; - known uses and counterexamples, marking missing evidence explicitly; - relation endpoints, direction and rationale; prerequisites kept distinct; - evidence maturity, quality constraints and unresolved questions; - disposition and links to the changed catalog/pattern files and follow-up tasks. Synthetic fixtures cannot establish known uses or satisfy evidence admission. Do not infer recurrence from one source. Draft patterns may retain hypothesis maturity; do not silently raise it because a model gave a favorable critique. Cross-source patterns should retain all source-specific candidate mappings. For later bench graph inspection, materialize reviewed candidates as `kind: entity` artifacts with a Definition section and a preserved canonical ID, and relations as typed Subject/Predicate/Object artifacts whose endpoints resolve. This graph-export adapter remains part of FEP-WP-0004; proposal tables are not a graph export.
