The reap_old_logs reset command continues if reset fails. check_node.sh now combines command exit status with output matching for normal checks, while inverted checks evaluate output regardless of exit status. On timeout, it prints the last command’s exit status.

No correctness problems found. set -e is in the right blocks, and the assertions that now gate match what both agents write (log paths under package_name, the START flag, the step flag names, history/<pkg>.json). Both operator-agent jobs are green.
A few minor notes, inline plus one here. None of them block this PR, and any of them can be a follow-on ticket rather than a change here. Happy to file them if that's easier.
reap_old_logs/chainsaw-test.yaml:31, not in the diff: the pre-runnodewright reset ... --confirmlacks the2>/dev/null || trueguard thatsimple/has. The current CLI returns 0 when the CR is absent, so it passes today, but the two scenarios handle the same reset differently, and nothing in the suite would catch a CLI change that makes it exit non-zero.

Chainsaw runs script.content as `sh -c` with no `set -e`, so only the last command's exit status reaches the test and every check_node.sh call above it is decorative. Three blocks in the pre-existing scenarios had this: - simple/: five assertions -- log content twice, the START flag, the step flag path and the history file -- of which only the final `ls .../history` gated. The log-content and flag-path checks, the ones that would notice a format drift between the two agents, could not fail the test. - reap_old_logs/: the survivor block's `^5$` count did not gate; only the `newest` content check after it did. The seed block's `^7$` count already gated, since the check_node.sh call was that block's only command; `set -e` goes in there too so a second check added later is gated from the start. interrupt/, dont_write_logs/ and the scenarios added in #605 and #673 already set it. This is the remainder. The cleanup blocks (`rm -rf ... || true`) are intentionally non-gating and are unchanged. reap_old_logs/'s pre-run `nodewright reset` gains the `2>/dev/null || true` guard simple/ has, so the two scenarios treat an absent CR the same way. check_node.sh also stops counting a positive match when the command itself exited non-zero: `cat a.log b.log` prints a.log and fails on an unreadable b.log, and that output must not pass a check. Inverted checks assert absence, where a command with nothing to list exits non-zero by design, so they keep matching on output alone. The failure diagnostic now prints the exit status. This suite is the parity contract the Go cutover (#222) leans on; until now "the suite passes" meant one of five simple/ assertions passed. Closes #680 Signed-off-by: Riley Rice <rrice@nvidia.com>

Description
Closes #680.
Chainsaw runs
script.contentassh -cwith noset -e, so only the last command's exit status reaches the test and everycheck_node.shcall above it is decorative. Three blocks in the pre-existing operator-agent scenarios had this:simple/— five assertions (log content ×2,STARTflag, step flag path, history file), of which only the last,ls .../history, gated. The log-content and flag-path checks — exactly the ones that would notice a format drift between the Python and Go agents — could not fail the test.reap_old_logs/— the seed block (^7$count) and the survivor block (^5$count and thenewestcontent check): two of three gated.interrupt/,dont_write_logs/, and the scenarios from #605 and #673 already set it; this is the remainder. Cleanup blocks (rm -rf … || true) are intentionally non-gating and untouched. The change isset -eas the first line of each of the three blocks.This is the same class of defect Brian identified reviewing #605's new scenarios; these are the pre-existing instances flagged there and left alone because they are contract scenarios. The suite is what #222's cutover argument rests on, and until now "the suite passes" meant one of five
simple/assertions passed.Review changes. The
reap_old_logs/seed block was already gated (itscheck_node.shcall was the block's only command), so it is two of three there, not one; the^5$survivor count was the hidden check. From review: thesimple/block carries the same one-lineset -ecomment its siblings do;reap_old_logs/'s pre-runnodewright resethas the2>/dev/null || trueguardsimple/has; andcheck_node.shcounts a positive match only when the command exited 0 (inverted checks keep matching on output alone, sincedont_write_logs/asserts absence by listing a directory that may not exist). Follow-ons in #686.Checklist

Locally: all scenario YAML parses, a scan confirms zero remaining ungated
check_node.shblocks across the suite,make license-header-checkclean. The e2e itself needs a cluster and runs in CI here against both agents — if any of the newly gating assertions fails, that is a real finding the suite had been hiding.
