The bitcoin app vanished from updated nodes: the container exited instantly
with 'sh: Syntax error: "fi" unexpected'. My 1.7.124 change added an
explanatory comment INSIDE the manifest's folded YAML scalar (>-), where
'#' is not a comment — it is literal text that reaches the shell. Folding
joins lines with spaces, so the comment swallowed the 'if ... then' while
the more-indented echo survived as its own line, leaving an orphan 'fi'.
bitcoind never ran, the container exited, and the app disappeared from the
UI because detection is container-based.
Explanations now live above the '- >-' line where YAML really treats them
as comments. The loopback-conf tolerance (-allowignoredconf=1) is unchanged
and still needed.
Adds scripts/check-manifest-shell.py to the release gate: it runs 'sh -n'
over every embedded manifest script and rejects '#' inside these scalars.
Nothing validated this shell before — no YAML parse or Rust test could have
caught it, and it only failed on the node, after signing.
