🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Reject exact command text that is not executable.
hasExactShellCommand checks only trimmed text lines. It returns true for a command inside a PowerShell block comment, an uncalled function, or a disabled shell branch. For example, this Windows step contains the exact line but does not run the test:
run: |
<#
bun test --isolate tests --shard=${{ matrix.shard }}/4
#>The step has no if, so lines 182-184 accept it. The Windows workflow currently uses a single-line run, so compare the trimmed run value directly in this Windows-specific check. If multiline scripts must remain supported, add shell-aware parsing and regression coverage for non-executable blocks.
Proposed fix
- const windowsTestSteps = winSteps.filter(step => hasExactShellCommand(step.run, windowsTestCommand));
+ const windowsTestSteps = winSteps.filter(
+ step => step.run?.trim() === windowsTestCommand,
+ );Also applies to: 176-184

When the Windows Test step wraps the command in a PowerShell block comment such as <#\nbun test ...\n#>, this filter retains the command line and hasExactShellCommand returns true, even though the step executes no tests; the step has no explicit shell, so Windows uses PowerShell. This leaves the same silent no-test regression the new assertion is intended to prevent. Compare the trimmed run value directly with the expected single-line command, or otherwise account for PowerShell block comments rather than filtering only lines beginning with #.

CI here is blocked by a base-branch problem, not by this diff, and I've stopped rerunning it. Both attempts on The stall is always the same shape: output stops right after a test that starts a proxy listener, then nothing for ~14 minutes, then cleanup reports I had been calling this flake all day — five occurrences across four unrelated branches plus Holding this PR rather than rerunning until green. The change itself is test-only and verified locally (full suite 10009 pass, both ablations reproduced), but merging on a retry-until-green would be exactly the habit #1302 warns about. |

…ng (#1316) Published devlog 028/029 as #1314, rebased #1301 onto current dev, and reported #1244's new conflict to its author. The part worth keeping is a retraction, and its own correction. I claimed two CI runs shared a stall signature -- cli-native-profile handing off to cli-restart-health with 'killed 1 dangling process' last -- and posted it to #1302 as a narrowing. False: run 31152916419 never hung at all. It hit the Bun epoll_ctl error while loading autostart-health, kept running, and finished as a failure in 85 seconds. I had compared two logs by memory of what one of them said. Then the retraction itself was wrong twice. It named claude-messages-endpoint as the first affected file in 31263738953, when that is where output stops and baseten-provider is where the error first appears -- two different questions I had collapsed into one column. And it said the EEXIST has 'two outcomes', which asserts causation the logs do not establish: the error appears in all three runs, one of which completed normally. Three passes to state three sentences accurately. Both corrections are public on #1302 with the chain left visible. Also corrected here: 'two cancelled runs at the exact head' was wrong -- they were consecutive heads, before and after the rebase.
…1185) The assertion that the Windows leg shards the suite used `.includes()` on the step's `run` text, so any occurrence of the command anywhere in the script satisfied it — including inside an `echo`, or in a comment. A Windows job that printed the command instead of running it kept the suite green. `hasExactShellCommand` splits the script into lines, drops blanks and comments, and requires the exact command as a whole line. The negative assertion against `echo <command>` pins that behaviour so a future loosening back to substring matching fails here rather than silently. Republished from #1185 by luvs01, whose branch was 324 commits behind dev. Rebased onto 14e9485 with no conflicts; authorship preserved below. Co-authored-by: luvs01 <luvs01@hanmail.net>
Maintainer-added coverage for the #1185 republish. Binding the assertion to an executable line closes the echo/comment hole, but a step carrying the exact command still runs nothing under `if: false` — the suite would stay green against a Windows leg that never tests. Ablated both ways against current dev: replacing the run line with `echo <command>` fails the contributor's assertion, and adding `if: false` to that same step fails this one. Neither mutation is caught by dev today.

… closed (#1322) Two of the four contributor-held PRs resolved. @Wibias met every condition on #1244 -- rebase, Russian locale parity, two completed non-cancelled CI runs at the same SHA -- including resolving the conflict I created by merging #1305. Verified independently: two CI successes at d5e70a2 and a local full suite of 10120 pass / 0 fail on that head. Landed as c75e68e, 58 files. #241 closed with its chain named, since #1244 references #1056 rather than #241. #1301 rebased again after drifting 33 behind, then merged with --admin over a red test 1/4. The failure is a 5000ms timeout in tests/crash-guard.test.ts, which my one-file diff to tests/ci-workflows.test.ts cannot reach, and which passes 14/14 locally three times. Logged as MERGE-DESPITE-CI with the reason rather than as a clean green -- and recorded that this is the same shape of reasoning I criticised as 'rerun until green' earlier. #1272 hit a tenth #1302 occurrence and was rerun but NOT merged: it is still a draft and those boxes are the contributor's attestation. A broken CI is not a reason to tick them -- it is a reason not to, since they assert what CI can no longer confirm. Method note: rerun-failed-jobs overwrites the job log, so I destroyed the #1302 evidence by fetching it after the rerun. Capture first, then rerun.

Binding the assertion to an executable line closes theechohole but not the neighbouring one: a step carrying the exact command still runs nothing underif: false, and the suite would stay green against a Windows leg that never tests.
