A non-numeric MAM_READY_EMPTY_GIVEUP, SKS_EMPTY_GIVEUP, SKS_IDLE_RETRIES,
SKS_IDLE_RETRY_BACKOFF_S, MAM_LOCK_STEAL_RETRIES, MAM_DIFF_MAX_BYTES,
MAM_DIFF_MAX_LINES or RECONCILE_POLL_INTERVAL was a `[` error or a sleep
error at the point of use (PR #43 review claude R3). They now go through
mam_int_knob: decimal, a warning and the default for a bad value. Minimums
are in test_issue26_ints.py INT_KNOBS: 1 for the give-up counts (0 acts as
1), the diff caps (0 truncates every diff) and the poll interval (0 is a
busy loop); 0 for the retry counts (one attempt) and the retry backoff.
SKS_QUIESCENT_INTERVAL stays raw: its default is 0.5 s and sleep's
fraction is its meaning; NOT_ARITHMETIC says so.
loop_lock.sh and diff_collect.sh also run without lib.sh (the Python runner
and the tests source them alone), so mam_int / mam_int_knob move verbatim
to lib_int.sh, which lib.sh sources and those two source when the function
is missing. remove.sh's no-manifest fallback list names the new file
(install copies every file under .agents/skills). test_issue21_loop_b l15,
which builds a control root holding only diff_collect.sh, copies it too.
Tests: the table guard now reads every shell file; scripts sourced alone
read their knobs as decimal; _pane_quiescent with SKS_EMPTY_GIVEUP=abc
gives up with a warning and no `[` error (14 of the new cases fail at
0051fd6).

delegate_job writes the prompt to a temp file under the control root's .mam/
and hands the wrapper --prompt-file; the file is removed once the wrapper
returns. An OSError from starting the wrapper becomes a failed submit (rc 126)
that the existing error branch logs, so the session-busy retry no longer
dereferences a missing result. A retry that yields no job id, and a
compliance job that cannot be registered, are now logged instead of silent.
The collector caps are documented as the size of the evidence a reviewer is
shown; delivery has no cap of its own any more. The loop skill notes that a
pipeline hides the loop's exit code.

Active with --worktree/--base only; without them prompts, flow and promotion
are unchanged (a loop_id is recorded in the checkpoint either way).
- Every review round is pinned (B3): the source's HEAD and its working state
as a tree built through a temporary index (the real index/status/refs are
untouched); a dirty state becomes a ref-less snapshot commit on HEAD
(committed as mam-loop, not as the user). An untracked nested repository
cannot be pinned and is refused. identity = (loop_id, base, head, tree).
- Review isolation (B4): a detached review worktree of the snapshot under
TMPDIR (default), or `--review-isolation env` (the source root with env and
temp-dir instructions). Failing to open the tree refuses the round - the
isolation is never lowered silently. Trees are removed after the round and
on any exit (run() wraps the body; release_guard too).
- The reviewers' diff comes from the snapshot (B13):
diff_collect.sh takes an optional head commit for a commit-to-commit diff;
its two-argument form is byte-identical.
- Stale rounds (B7/B8): after the round the source is measured again; if it
changed, the round's approvals are discarded and the next iteration
re-reviews without a correction job (last iteration: rc 1). Only the last
non-stale round's PASSes are promoted.
- Records (B9/B15): review_rounds in the checkpoint with per-reviewer
transport/evidence, and report-<jid>.identity.json next to each promoted
report: evidence review-tree | source-tree | diff-only.
- Pre-promotion re-check (B10): a source changed after approval is not
promoted (rc 1).
- Remote reviewers (B14, Creator challenge 91c81095): they cannot reach this
host's review tree. Checked before anything is delegated: refused by
default; `--remote-review diff-only` admits them with the snapshot SHAs and
diff as their only evidence (no local path in their prompt), and refuses a
round whose diff is truncated or unavailable.
- run_loop.sh accepts both options (usage identical to the runner's); the
legacy shell loop refuses them before the lock.
Tests tests/test_issue21_loop_b.py L1-L16 (22).
