PR 29251 runtime verification, Linux x86_64
main: a036489016 (github/main)
PR: 19ffe9c20e1c499faa2abc00d49471a27a9e1b9b

Both checkouts: timeout 600 vp i
Both: vp run dev in a captured background process; only one dev server at a time.
Playwright 1.60.0 + /usr/bin/google-chrome: added /home/user/cache-verification through Add project > Local folder; selected Codex gpt-6.1-sol; sent a real README tool-read turn. Both returned CACHE_PATH_OK compile cache verification.

Both: timeout 1500 vp run dist:desktop:artifact --platform linux --target AppImage --arch x64 --keep-stage
AppImage and DEB artifacts built successfully. DEB installation was not exercised.

Server then listened on http://127.0.0.1:17774; authenticated client and persisted thread loaded.

Packaged main web client: real Codex gpt-6.1-sol README tool turn -> CACHE_PATH_OK compile cache verification.
Packaged PR web client: same turn -> CACHE_PATH_OK compile cache verification.
After new FUSE mount and backend restart, same thread and follow-up -> RELOCATED_OK compile cache verification.
After removing manifest only in the unpacked build, same thread and follow-up -> FALLBACK_OK compile cache verification. Reload retained all three responses.
AppImage temporary writable cache directories were removed on graceful exit.

Blacksmith: vp test run scripts/lib/server-compile-cache.test.ts: 5 passed.
Blacksmith: vp run check:changed 47f2c8d29e981c7723467efe137ee19e91df924e --concurrency 1: format, lint, both knip steps, 6-package typecheck and 6 selected tests passed.

No source changes, commits, or pushes.
Not verified: end-to-end startup speedup, desktop renderer interactions (CDP endpoint did not answer), DEB install, non-Linux and ARM64 execution, mobile clients, remote/relay connections, other providers, damaged-bytecode real-client fallback. Existing focused tests cover malformed cache behavior.
