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.

R1 (P1): a quoted export still ran code when the key was a bash special
variable (RANDOM=a[$(cmd)] is evaluated arithmetically on assignment).
envfile.RESERVED (bash's own variables, plus BASH_/COMP_/READLINE_
prefixes) is skipped with a line-numbered warning by both loaders; a test
keeps it covering every variable a clean bash defines. The wrapper also
hands SCRIPT_DIR/REPO_ROOT/TARGET_ENV to the parser as environment, so the
file cannot replace the variables it has already set.
R2 (P2): SKS_QUIESCENT_TRIES reached `for ((i < tries))` through a function
argument; it is normalised at the call site (minimum 0). B5 now requires
every integer-looking env default in the shell code to be normalised or
listed in NOT_ARITHMETIC with where it goes, and exercises _pane_quiescent.
R3 (P2): _positive_int strips leading zeros and rejects more than nine
significant digits before int(), like mam_int; 5000-digit inputs no longer
raise in the runner.

bash read MAM_JOB_TIMEOUT_S=0700 as octal 448 (and failed on 0900) while
the loop runner read 700. One rule now, with a per-knob minimum:
lib.sh mam_int / mam_int_knob and runner._positive_int (blanks allowed,
digits only, decimal, min <= n <= 999999999).
- minimum 1: MAM_JOB_TIMEOUT_S, MAM_HEARTBEAT_SEC, MAM_HEARTBEAT_MISSES,
MAM_ACK_TIMEOUT_S (invalid env: warning + default) and the wrapper's
--timeout/--idle-timeout/--heartbeat/--heartbeat-misses/--ack-timeout
(invalid: rc 1); the runner's job_budget, --job-timeout, contract_args.
- minimum 0 (0 = check once): MAM_INJECT_ACK_GRACE_S,
delegate_wait_started's ack_s, SKS_DIALOG_TIMEOUT, SKS_BUSY_TIMEOUT,
SKS_DELIVERY_GRACE_S.
- tests/test_issue26_ints.py: INT_KNOBS is the one table of minimums; a
static guard keeps env defaults out of arithmetic and checks each
normalised knob against it.
