sync.js

// nb-web sync.js — extracted from main.js (tier-2d modularization, 2026-07-06).
// NbSync: git wire/log commands, generic run-command dispatch (cal/daily/info/
// weather).
//
// Cross-references rewritten during extraction (all other lines verbatim):
//   _showCmdOutput(cmd, text)  -> NbMain.showCmdOutput(cmd, text)
//   _showPreviewLoading()      -> NbMain.showPreviewLoading()
//     Both were NEWLY EXPOSED on NbMain's return object in this same commit
//     (bare-reference delegation to the existing private main.js functions,
//     NOT moved -- they're genuinely shared utilities also called by runGrep
//     (Grep section) and the import flow (Util section), both of which stay
//     inside NbMain's closure. Moving them would have required exposing them
//     publicly anyway for THIS module's sake, so they stay where multiple
//     callers already are: the kernel.
//
// Deleted rather than carried forward (unlike prior tiers' "defer dead code
// to tier-5" default): doSync(), _bindSync(), showNotebooksWelcome() were all
// confirmed zero-caller dead code via full-repo grep, same as tier-2b's
// openToday/showAddForm -- but this is a brand-new file with no pre-existing
// diff to preserve, and the deadness analysis was already fully done in this
// same review pass. Deleting cost nothing extra and left no dead public API
// surface (NbMain.doSync in particular would have read as a live entry point
// that silently no-ops). Tier-5's dead-function list is now just
// _setFilterBar/_injectRenderingNotice (both still genuinely in main.js).
