Stabilize tar extraction in download-fw-headless-project

[myieye]

[Claude, autonomous]

GNU tar (Git Bash) reads the colon in D:\... as host:path, so task k8s:download-fw-headless-project never extracted there. Pass a relative posix path instead.

Which tar you get depends on PATH order, so both were checked on Windows:

tar	old (absolute)	new (relative posix)
C:\Windows\System32\tar.exe (bsdtar, first on PATH in pwsh)	OK	OK
C:\Program Files\Git\usr\bin\tar.exe (GNU tar, first on PATH in Git Bash)	fails	OK

📝 Walkthrough

Walkthrough

The download script now uses a relative POSIX extraction path. It tracks extraction success and preserves the local tar file when extraction fails, allowing cleanup to support retries without another download.

Changes

Archive handling

Layer / File(s)	Summary
Relative archive extraction deployment/download-fw-headless-project.js	extractTarFile passes a relative POSIX-normalized destination path to tar.
Retry-aware cleanup deployment/download-fw-headless-project.js	main tracks extraction success. cleanup preserves the local tar after failed extraction and deletes it otherwise.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 27b09

Windows extraction is improved, but retrying after extraction failure still downloads the archive again and requires pod availability. The retry flow should reuse the preserved local tar before merge.

Poem

A rabbit checks the tar by moonlit light
The path turns tidy, slash by slash, just right
If unpacking fails, the bundle stays
For one more try on future days
Then cleanup hops along its way
