Changes

• Validate JSON payloads against the embedded request schema before ordinary or paginated API requests, including dry runs.
• Reject malformed JSON, empty required bodies, missing required fields, type and enum mismatches with usage exit code 2.
• Warn on unknown structured properties without dropping them from the HTTP payload or blocking spec drift.
• Validate a private payload projection against the original schema, preserving closed oneOf discrimination, composed array items, typed/open maps and shared schema contents.
• Keep payload values out of validation diagnostics and warnings off stdout.
• Add inline/file/stdin, nested schema, composition, immutability, dry-run and no-network regressions; document the behavior.

Validation

On head 2b7647cf5acea82380c7d0e7eeea7dfd7653c8ef, CI run 40864712290 passed both jobs:

• build: go build ./..., embedded-spec drift check, all tests and coverage gate passed. Total coverage 81.5% (80% gate).
• lint: formatting, vet, ineffassign, spelling, complexity and golint passed.
• No tests run locally, as requested. All six changed files were re-read from the exact remote head.
• Focused independent review found closed oneOf and composed-array warning edge cases; both now have regressions.

Scope

Refs PLAT-1314. Other checklist items and open PR scopes remain separate. Validation uses the existing kin-openapi OAS validator; this does not add a new JSON Schema engine or change embedded specs.
