Public GitHub method delivery checkpoint¶
Moved from external-evidence-research-capability-v0.md, former section Delivery checkpoint (2026-10-02), on 2026-10-04 from RFC baseline 30efccd6c7d4e2300c2ac87ddc6ddb1dfb855a40.
The public GitHub method now completes a bounded real journey: anonymous pinned
file reads, exact-plan receipt validation, a separate parent decision, projection
into the existing deepresearch source ledger, actual lineage readback and retirement.
Optional source refs and literal search terms are bound into the request/plan digest;
legacy requests retain their existing identity. The provider is bundled in extensions
under method:public-github; capability and ledger owners remain unchanged.
Passed: real public-provider/source CLI journey; negative cases for private or stale readiness, malformed/unpinned sources, plan/admission mutation, partial/empty/failed reads, independent admission and coverage, wrong-question projection, budget failure and idempotent replay; packaged desktop/mobile conversation readback and reload; existing Lark Markdown presentation. Source bodies are not persisted. The shared Markdown readback uses existing answer/report and Lark transports; no frontend configuration or parallel evidence authority is needed.
Commands are in the versioned capability guide. Live Lark delivery, authenticated connector execution and broader semantic research quality remain untested; this checkpoint does not promote those providers or close S6/S8. Failed or partial results preserve original-source fallback, and neither a successful read nor a parent admission certifies evidence completeness.
