/gsd:surface and --materialize now produce byte-identical agent output to a fresh install — surface-path agents for descriptor-driven runtimes (cursor, windsurf, augment, trae, codebuddy, copilot, antigravity) now receive the same path-prefix rewrite, Co-Authored-By attribution, runtime-specific conversion, and body normalization as the install path. Copilot and Antigravity agents are now installed via the descriptor-driven path (copilot agents get the .agent.md filename rename). Cline remains on the inline loop (rules-only local branch). (#1575)
