── SYSTEM ──
Do NOT include `uofa:residualRiskJustification`, `uofa:consideredAlternative`,
or `uofa:knownLimitation` in the generated package. These are reserved for
v0.6 rules and should not appear in v0.5-era test data.

You generate synthetic simulation-credibility evidence in JSON-LD for ASME
V&V 40 analysis. Packages are used to test a weakener-detection system.

Requirements:
1. Structurally complete. All required fields populated.
2. Passes SHACL validation against the vv40 pack.
3. Contains exactly the targeted weakness described below.
4. Plausible on a quick read. The flaw must be subtle, not trivial.

Output ONLY the JSON-LD package as a single valid JSON object. No commentary.
No markdown fences. No trailing text. Close every brace.

Task: generate a UnitOfAssurance package whose `bindsClaim` IRI resolves to an inline Claim node that does NOT carry `prov:wasDerivedFrom`. The claim should look meaningful (purpose, statement, scope) but lack the structured derivation link to Evidence.

The Claim is brief (one sentence) and has no provenance fields at all. The package text mentions evidence in passing but does not link any IRI to the claim.

W-EP-01 TRIGGER (CRITICAL — do not skip):
Emit `bindsClaim` as an IRI on the UnitOfAssurance and include an inline Claim object in the package (or referenced by IRI) that has `type: "Claim"` and a `name` and `description` but does NOT have `prov:wasDerivedFrom` (or `wasDerivedFrom`). Other package nodes (ValidationResult etc.) MAY have wasDerivedFrom; the Claim itself must lack it.

SCHEMA RULES (non-negotiable — deviations fail SHACL):
- type values are JSON strings (not arrays except for the top-level `type`).
- `requiredLevel` and `achievedLevel` are INTEGERS 1..5. Never strings like
  "Gradation 2". Emit `"requiredLevel": 2`, not `"requiredLevel": "Gradation 2"`.
- `factorStatus` must be one of: "assessed", "not-assessed", "scoped-out",
  "not-applicable". Never "Met", "Complete", "Passed", etc.
- `factorStandard` stays as "ASME-VV40-2018".
- `hasContextOfUse`, `hasDecisionRecord`: inline objects with `id` field.
- `hasValidationResult`: array of inline objects, each with `id` and `type`.
- `bindsRequirement`, `bindsModel`: IRI strings.
- `bindsDataset`: array of IRI strings.
- `hasWeakener`: empty array [].
- `generatedAtTime`: ISO-8601 string, e.g. "2026-04-19T00:00:00Z".
- `hash`: "sha256:" followed by exactly 64 lowercase hex chars.
- `signature`: "ed25519:" followed by lowercase hex chars.

Profile dispatch (Phase 2.5 v0.5.15.1):
- If `conformsToProfile` is `https://uofa.net/vocab#ProfileMinimal`: emit
  ONLY the minimal-required fields above. DO NOT emit Complete-profile-only
  fields like `hasSensitivityAnalysis` (that triggers SHACL violations on
  Minimal profiles).
- If `conformsToProfile` is `https://uofa.net/vocab#ProfileComplete`: in
  addition to the minimal fields, also emit:
    `hasSensitivityAnalysis: true` (BOOLEAN, not an inline object — the
        v0.5 schema declares this as xsd:boolean per W-AL-02. A boolean
        true value indicates a sensitivity analysis is documented as
        part of the package),
    `hasContextOfUse.hasApplicabilityConstraint` (inline object with
        id/type/name/description),
    `hasContextOfUse.hasOperatingEnvelope` (inline object with
        id/type/name/description).
  Mixing Minimal-only fields with Complete-profile declarations is the
  most common SHACL `sh:or` violation; Phase C holdout showed CE specs
  hit this 21% of the time.

Required top-level fields (emit EXACTLY these values):
  "@context": "https://raw.githubusercontent.com/cloudronin/uofa/main/spec/context/v0.5.jsonld"
  "synthetic": true
  "type": ["UnitOfAssurance", "uofa:SyntheticAdversarialSample"]
  "conformsToProfile": "https://uofa.net/vocab#ProfileMinimal"
