Phase 9: Code Reviewer

Correctness Fixes Applied

removed better-sqlite3 from the desktop runtime and replaced it with node:sqlite
fixed packaged runtime resolution for electron-log/main.js
bundled local adapter workspace packages into the main-process build instead of leaving broken runtime imports behind after packaging
hardened trusted-sender checks for IPC invocation
pinned connector commands to audited runtime defaults instead of accepting arbitrary renderer overrides
scoped secrets to companies and resolved secret bindings by companyId
validated worker messages at runtime instead of trusting unchecked casts
closed a test coverage gap where *.test.ts files were present but excluded from Vitest

renderer responsiveness is acceptable for the current feature set, but continued extraction of shell sections into smaller components remains a maintenance priority
heavy agent execution stays out of the renderer through the utility process boundary
background database work is local and bounded; privileged tasks do not run directly in the renderer
critical run lifecycle writes now execute transactionally
lint baseline is now warning-free via eslint.config.mjs and pnpm lint

the renderer bundle is still large enough that future work should split heavier sections and defer rarely used surfaces
cross-platform production profiling has not yet been run on Windows and Linux hardware

renderer JS bundle (out/renderer/assets/index-*.js): 1,162,405 bytes (~1.11 MB)
renderer CSS bundle (out/renderer/assets/index-*.css): 43,344 bytes (~42.3 KB)
main bundle (out/main/index.js): ~142.9 KB
main connector chunk (out/main/chunks/connectors-*.js): ~146.2 KB
preload bundle (out/preload/index.js): ~137.7 KB

The primary optimization target remains renderer bundle splitting and lazy-loading of low-frequency surfaces.
