Merge-workspace review of PR #43 (codex R1-R4, claude R1/R2).
- R1: envfile.parse raises EnvFileError when the file exists but cannot be
read or decoded as a whole; `--shell` prints the cause and exits 1, so the
wrapper stops (rc 1, as before #26) instead of running on defaults, and
mqtt_common's entry points stop on the same error. A bad single line is
still a warning. The wrapper's message no longer claims a read failure
when the cause is elsewhere ("cannot load ... see the line above").
- R2: lib.sh mam_int spells out the ASCII blanks and digits instead of
[[:space:]]/[0-9], which follow the locale: U+2003 30 U+2003 was 30 in the
wrapper and invalid in the runner under en_US.UTF-8. The test oracle
_expected uses the same ASCII rule.
- R3: an integer flag given explicitly with an empty value is refused like
any other invalid value; only an absent flag keeps its default.
- R4: a line holding a NUL byte is skipped with a warning by both loaders;
before, the wrapper read "leftright" and the Python loader died.
- .mam.env.example states the format: no expansion, `export` and bash's own
variables skipped, a trailing `# ...` is part of the value, the environment
wins, an unreadable file is an error.
Tests: unreadable (0000) and invalid-UTF-8 files stop the wrapper and the
Python loader; a NUL line is skipped by both; Unicode blanks/digits are
invalid for mam_int, _positive_int, the wrapper and the runner under C and
en_US.UTF-8; explicit empty values for the five integer flags are refused.
All of them fail on b58edac.
