PR 29241, head ee54c481a85486eda2c58a0e8b96c9bceb9da163
Linux x86_64, 4096-byte pages. Real GitHub release 0.1.6; no mock executable or release mirror.

BEFORE: github/main 55e2538561
cwd=/tmp/t3-verify/main
T3CODE_HOME="relative home" T3CODE_INSTALL_BIN_DIR=/tmp/t3-verify/bin-main T3CODE_VERSION=0.1.6 sh /home/user/main/scripts/install.sh
Installed T3 Code 0.1.6
readlink: relative home/runtime/versions/0.1.6/t3
cd /tmp; /tmp/t3-verify/bin-main/t3 --version
No such file or directory (exit 127)

AFTER: exact PR head
Same cwd and T3CODE_HOME, separate absolute bin directory, PR installer.
Installed T3 Code 0.1.6
readlink: /tmp/t3-verify/main/relative home/runtime/versions/0.1.6/t3
cd /tmp; /tmp/t3-verify/bin-pr/t3 --version
t3 v0.1.6 (exit 0)

Fresh real downloads also passed for default home, absolute home with spaces,
relative home with spaces and newline, and a cwd ending in newline.
Each exact absolute symlink target matched; --version from /tmp passed;
reinstall reused the downloaded version and passed.

Installed CLI project add against PR dev server: exit 0, project created.
Chrome/Playwright: paired with PR dev server, submitted actual provider turns.
Codex app-server protocol: turn/start model=gpt-6.1-sol; turn/completed status=completed.
Agent ran pwd and git branch --show-current; replied "sol provider follow-up verified".
Reloaded client: completed reply persisted and composer returned to idle.

Blacksmith: installer tests 7/7 passed.
check:changed against PR base 47f2c8d29e98: format, lint, both knip passes,
scripts typecheck, and installer tests passed.

LIMIT: release 0.1.6 fails its own --version check when the install home contains
an actual backslash: ERR_INVALID_MODULE_SPECIFIER in @cursor/sdk module resolution.
The fake-executable test cannot establish full runtime support for that pathname.
No source changes made for this separate release-runtime limitation.
macOS, Windows, native mobile, Electron shell, and long-term service pruning unverified.
