Two harness-side bugs that made a broken wn silently look like a working one:
1. whitenoise-skip-unprocessable-retry.patch's hunk header declared
`@@ -178,7 +178,23 @@` but the new side only has 22 lines. GNU patch
bails with "malformed patch at line 26" and leaves the target file
untouched. Fix the count to +178,22 so the patch actually applies.
2. setup.sh's patch-apply loop piped `patch` through `tee`, which
masked patch's exit code behind tee's. A miscounted hunk therefore
still touched the `.headless-patched-*` marker and the next run
skipped the "patch" step entirely, so the resulting wn ran the
stock 10-retry exponential backoff on every MlsMessageUnprocessable
— ~17min per event, which pegs the per-account serial event
processor and makes every later test timeout "just because".
Check patch's real exit status; fail preflight loudly instead.
Same class of bug was also hiding cargo build failures: the
`cargo build ... | tee` pipeline reported success even when rustup
couldn't fetch the toolchain manifest (503 from static.rust-lang.org)
or cargo couldn't hit the crates.io index (503 from fastly). setup.sh
then `info`-logged the expected binary paths and happily moved on —
until the daemon launch tripped over `nohup: No such file or directory`.
Now each cargo build runs in a 4-attempt retry loop that terminates
only when the binary actually exists on disk, and fails preflight
loudly if it never materialises. Matches the jitpack 503 retry
behaviour already in place for `:cli:installDist`.
