-# Pattern Schema
+# Pattern schema 0.1
 
-Each pattern consists of structured metadata plus explanatory prose.
+Status: working contract · 2026-09-24 · FEP-WP-0002-T01
 
-## Canonical metadata
+[Pattern template](../templates/Pattern.md) is the authoring skeleton;
+[vocabulary.yaml](vocabulary.yaml) owns serialized enum values and force IDs.
+The template is intentionally incomplete and is not a pattern record.
+
+## Identity and lifecycle
+
+- `schema_version: '0.1'` identifies this metadata contract.
+- `id`: `FEP-` followed by four digits, allocated once when creating a pattern file.
+  IDs do not encode families or scale; moving or renaming a pattern retains its ID.
+  Never reuse a retired ID. Check all pattern frontmatter before allocating the next
+  unused number. Candidate P01 identities remain scoped to their source workspace.
+- `name`: human-readable name; `family`: nonempty list of family keys; `scales`:
+  nonempty list of distinct L0–L7 keys. Do not serialize `cross-scale` or `L3/L6`.
+- `status`: draft, reviewed or deprecated. Reviewed means an editorial review is
+  recorded in Evidence; it does not establish empirical maturity. Deprecation must
+  explain the replacement or reason, and existing references remain resolvable.
+- `evidence.maturity`: hypothesis (untested generalization), emerging (traceable
+  support and contrasting cases with explicit gaps), established (independent known
+  uses and documented limits), canonical (established evidence plus explicit corpus
+  review for reference use). None means universally desirable. Promotion requires
+  a linked review, never a model score or a count of citations alone.
+
+## Context, prerequisites and forces
+
+`context` and `prerequisites` are lists of explanatory strings. Prerequisites are
+conditions such as identifiable commands or a durability requirement. They are
+not unresolved pattern names. Use a `requires` relation only when another pattern
+is genuinely required, with its ID and a rationale.
+
+`forces.improves` and `forces.worsens` contain vocabulary keys such as
+`interaction-latency` and `implementation-complexity`. At least two distinct forces
+must be present overall, with both benefits and costs explained in prose. A force
+may appear on both sides only when the Forces section explains the conditions.
+Do not infer direction just from a label (lower latency is generally favorable).

-## Human-readable structure
+The nine pattern relation types in vocabulary.yaml target a `pattern` by stable ID.
+`implemented-by` targets `technology`; `observed-in` targets `system` or
+`architecture`. External targets use a repository-relative Markdown path to an
+existing mapping or case record. A product label or URL alone is not a graph node.
+`rationale` is required. `evidence` contains local evidence-entry IDs, or is empty
+when the relation is explicitly marked as a hypothesis in its rationale.
 
-Every pattern should contain:
+Use kebab-case relation names everywhere. Relations are recorded from this pattern
+to the target. Do not infer inverse edges, transitivity or symmetric closure.
+In particular, a cycle of complements is not itself an inconsistency. Requires
+cycles warrant review; a generic graph cycle count is not a correctness verdict.

-## Requirements
+Source IDs resolve in `research/catalog/SourceCatalog.md`. Each review path exists;
+claim IDs resolve within that review. E1 is local to the pattern, not a global ID.

-- describe a recurring problem,
-- expose at least two meaningful forces,
-- propose a reusable configuration,
-- explain consequences,
-- identify failure modes,
-- create or refine a context in which other patterns apply.
+## Prose and admission
 
-A useful technique is not automatically a pattern.
+All sections in the template are required. Explain a recurring problem, competing
+forces, reusable solution, dynamics, resulting context, consequences and failure
+modes. State unknowns explicitly rather than leaving misleading empty claims.
+A technique or framework feature alone does not establish a reusable pattern.
 
-A framework feature is not automatically a pattern.
-
-A pattern name should identify a reusable architectural idea rather than a product-specific API.
+[Worked fixtures](../research/examples/schema-contract.yaml) demonstrate resolution
+in a deliberately isolated synthetic corpus. Their IDs are not reserved in the
+real corpus and their contents provide no research evidence. The fixture check is
+an acceptance check for this contract, not the future full corpus validator.

+
+## Investigation question (editorial)
+
+What distinguishes a primary local copy from a subordinate cache? What additional
+sources or passages are needed to establish persistence, concurrency and recovery?
+
+## Excerpt boundary
+
+Do not infer that this fragment defines merge semantics or makes every copy an
+unrestricted writer. Its parent essay's domain and exceptions need separate review.

+# Schema and source preparation review
+
+Date: 2026-09-24 · Reviewer: codex (self-review)
+
+## Schema decisions
+
+The working 0.1 contract resolves the initial review's representation issues:
+
+- Stable FEP-NNNN pattern identities independent of mutable family/scale labels.
+- Editorial status separated from evidence maturity; seed remains a catalog label.
+- Explicit scale lists and registered kebab-case force IDs.
+- Conditions in prerequisites; pattern dependencies use typed requires edges.
+- Typed relation targets with justification and local evidence references.
+- Source IDs, review paths and claim labels form a traceable citation chain.
+
+The isolated synthetic examples exercise two pattern IDs, a relation endpoint,
+force lookup and a source/review/claim reference. No example becomes a corpus
+pattern. `make schema-test` checks agreement and resolution. A comprehensive
+validator and migrations for future versions remain in FEP-WP-0004.
+
+Outcome for FEP-WP-0002-T01: complete. This settles serialization for the first
+cycle; it does not validate the nine-responsibility theory or any candidate pattern.
+
+## Primary-source preparation
+
+SRC-0001 is the author's DEV publication, linked from Ryan Carniato's profile.
+Its displayed date is Sep 22; the API metadata request was denied, so the year
+has not been independently verified. The packet pins the accessed web edition.
+SRC-0002 is the authors' Ink & Switch essay, dated April 2019; it supplies a
+conference citation and DOI. We use the web edition, not an assumed identical PDF.
+
+Both packets retain short original passages, exact section/sentence locators,
+clear editorial boundaries, source URLs and SHA-256 digests. They isolate authority
+placement rather than attempting full article extraction. No existing research stub
+was used as a substitute for a primary source. Each workspace has a four-call plan;
+neither has been executed or independently reviewed.
+
+## Next evidence work
+
+Run the two bounded investigations, inspect claim fidelity and negative results,
+then extend source review to mutation, persistence, reconciliation and recovery.
+Do not complete FEP-WP-0002-T02 on the basis of these excerpts. The full case reviews,
+independent known uses, six-to-ten-pattern synthesis and VC-01/VC-02 remain open.
+No provider/model was chosen and no paid generation was started in this preparation.
