- Resolve 14 conflicts from popping local stash on top of origin'seed1e88+8d3352fdoc-comment additions (11 mechanical, plus version.rs, DashboardAuthenticatorTests.cs, DashboardGalaxyProjector.cs) - Fix 4 test files that used AGENTS.md as the repo-root sentinel (now use CLAUDE.md, since AGENTS.md was removed in4731ab5) - Redirect 10 doc citations from AGENTS.md to the matching gateway.md sections (Value Model, Status Model, Security, STA Worker Thread Model, gRPC Layer rule, cancellation rule) Verified: solution build clean, x86 worker build clean, 266/266 gateway tests passing, 121/121 worker tests passing.
