Two raw injections: (1) workspace-context plugin with meta.kind='workspace-instructions' (typed shape — version + changes[]); (2) unknown-kind raw injection so the fallback generic card path is exercised. Interleaved with a tagged (envelope='context') plugin inject so a reviewer can visually A/B them side by side. Kernel wire seat: packages/core/session/src/types.ts:239-251 (envelope + meta fields) plus packages/core/session/src/index.ts:236-243 (raw = no <context> tag wrap). Audited @ deepseek-harness-dev fa2065872."
