Add line-ending self-check; file findings from a real Windows Sandbox debugging session - #433
Conversation
…l Windows Sandbox debugging session A raw download of run_setup.bat (GitHub's Raw button, raw.githubusercontent.com) serves the file with LF-only line endings instead of the CRLF a real git checkout produces (.gitattributes' text=auto eol=lf normalizes the stored blob to LF; the *.bat eol=crlf override only affects checkout, never what GitHub serves raw). cmd.exe's goto/call label-seeking silently misbehaves on the result, producing a confusing partial run with no clear error -- confirmed as the root cause of a real debugging session (multiple pauses, a PyInstaller build loop with no environment behind it, some files written and others not). - run_setup.bat: new self-check as literally the first thing the script does (before any other goto/call, so it stays reliable even on a corrupted copy), failing fast with a clear, actionable message instead of a silent partial run. - README.md: TL;DR bullet recommending git clone over a raw download. - docs/open-questions.md: pro/con on fixing the distribution channel itself (gitattributes options vs. a verified-CRLF release asset), left for the maintainer to decide. - CLAUDE.md: Active Backlog Items 44-52 -- the line-ending finding plus several smaller, independently-verified findings surfaced while tracing false leads during the same debugging session (a :die non-halting cascade, a PowerShell capability preflight gap, a false "another instance running" lock message, a connectivity-prompt CI-safety gap, and two lower-confidence pipreqs/pyproj_deps errorlevel-handling findings, flagged with their actual verification status). - docs/agent-cold-storage.md: two lower-priority, trigger-gated items from the same session (a repair-loop attempt budget cap; broader binary-presence guards).

There was a problem hiding this comment.
On a normal git checkout this command still exits 1: [string]@([char]13,[char]10) casts a two-element array to a string by joining the characters with the default space separator, so the regex looks for CR-space-LF rather than an actual CRLF sequence. As a result every valid CRLF copy falls into the new error block and exits before bootstrap, leaving run_setup.bat unusable when dropped next to an app; use a literal CRLF pattern or build the string without array-to-string conversion.

This LF-only failure path is new observable bootstrap behavior, but no tests, NDJSON checks, or workflow artifacts changed in this commit, and the ordinary Actions checkout always produces CRLF so it will not exercise this path accidentally. If the self-check regresses, CI can still stay green; add a dedicated LF-copy/HP_* lane with an NDJSON row asserting the emitted error before shipping this branch.
Useful? React with 👍 / 👎.

Agreed this branch (LF-only copy) has no dedicated CI test today -- actions/checkout always normalizes to CRLF per .gitattributes, so CI can exercise the happy path on real cmd.exe every run but can never organically produce a broken file to test the failure branch against. This would need a dedicated HP_TEST_*-style hook (this repo's established pattern) plus a new selfapps scenario and NDJSON row.
Deliberately deferred rather than built into this PR: tracked explicitly in CLAUDE.md's Active Backlog Item 44 ("Known gap" note), alongside the same gap for the other two preflight branches (PowerShell absent, PowerShell-execution-fails). Filed as real, scoped future work rather than left silent.

distinguish powershell.exe execution failure from the subsequent line-ending
check. Capture the exit status of the -NoProfile -Command invocation separately,
report that PowerShell failed when it cannot execute, and perform the CRLF
validation only after successful execution.
- Around line 56-57: Update the PowerShell invocation in the CRLF check to pass

exit-status behavior used by the following errorlevel branch.
- Around line 56-57: Fix the PowerShell self-check in the run_setup validation
block by explicitly binding the batch-file path passed to -Command (for example
through a script-block parameter), then validate that line endings are
exclusively CRLF: reject bare LF, bare CR, and mixed endings while accepting
CRLF-only content. Add Windows CI coverage for CRLF-only, LF-only, and
mixed-ending inputs.

Two real bugs in the PowerShell one-liner, both confirmed by CI (every
lane failed within ~2 minutes) and independently caught by CodeRabbit
and Codex review, then reproduced and verified fixed against a real
locally-built PowerShell 7 binary (not just reasoned through again):
1. With a string-valued -Command, the trailing "%~f0" argument is NOT
bound into $args -- PowerShell parses it as additional command text,
not positional data. $args[0] was always empty, so ReadAllText()
threw on every single run. Fixed by passing the path through an
environment variable (HP_SELF_PATH) instead of a trailing argument.
2. [string]@([char]13,[char]10) does not concatenate the two chars --
PowerShell's default array-to-string conversion joins with $OFS,
which defaults to a space, producing "CR SPACE LF" instead of CRLF.
So even a correctly-passed path would never have matched. Fixed by
using plain single-quoted regex literals ('\r\n', etc.) instead --
simpler than the array-cast approach, and it lets the check reject
bare LF and bare CR too, not just confirm at least one CRLF exists.
Also addresses two more review findings, both real:
- Both pause calls now skip under HP_CI_LANE, matching the pattern
:die already uses elsewhere in this file (unconditional pause could
hang a non-interactive run whose stdin isn't closed/redirected).
- A genuine PowerShell execution failure (as opposed to a real LF-only
file) now gets its own distinct message via a third exit code,
instead of being misreported as a line-ending problem.
Verified via a real PowerShell 7 binary built for this sandbox: the
exact command string now in the file correctly exits 0 against this
repo's actual CRLF-checked-out run_setup.bat, and exits 1 against a
genuine LF-only copy of the same file.
Also: two lone apostrophes in new echo text (introduced while writing
this) each desynced check_delimiters.py's own quote-tracking the same
way the first one did in the previous commit -- fixed the same way.
CLAUDE.md Items 49-52 reworded to cite stable labels/subroutine names
instead of line numbers, per AGENTS.md's explicit convention (missed
in the previous commit), and Item 51's fenced code block now has the
blank lines markdownlint expects around it.

Thanks both — these were real, and the CI failure across every lane confirmed it immediately (the check was failing on a valid CRLF checkout too, which is worse than not having it at all). Pushed a fix in d6c6b1f, verified against a real PowerShell 7 binary built for this sandbox rather than reasoned through again:

Real Windows execution of the fixed check also still hasn't happened (noted in the PR description); the pwsh-7-on-Linux verification above is the closest available substitute for the PowerShell-semantics half of that gap, not a substitute for a real Generated by Claude Code |

Separate from the LF-only path, this new errorlevel 2 branch is observable startup behavior for cases where PowerShell is present but the line-ending probe cannot run, yet this commit adds no NDJSON assertion or forced CI lane for it. Normal Actions checkouts only exercise the CRLF happy path, so a future quoting/errorlevel regression here could silently remove or bypass the diagnostic without CI noticing; add an HP_* hook or dedicated lane that forces this branch and asserts the emitted message.

Same situation as the LF-only branch: no dedicated CI test exercises the "PowerShell present but the check's own invocation fails" (errorlevel 2) exit today. Needs its own HP_TEST_* hook to force this deterministically, plus a selfapps scenario asserting the emitted message and exit code.
Tracked in CLAUDE.md's Active Backlog Item 44 ("Known gap" note) alongside the other two preflight branches -- deliberately deferred as real test-authoring scope rather than built inline with the fix that was already in flight.
Generated by Claude Code
Both external PR reviews (Codex, citing AGENTS.md directly) correctly flagged that the new self-check has no dedicated CI test of its own -- a normal Actions checkout only ever exercises the CRLF happy path, so a future regression in either the LF-only or PowerShell-failure branch could go unnoticed. Real test-authoring scope, deliberately deferred rather than bolted onto the fix that was already in flight; recorded here so it does not get lost in a PR comment thread. Held locally rather than pushed immediately: batch-check.yml's cancel-in-progress concurrency group would cancel the CI run currently verifying the actual fix (d6c6b1f) if pushed now.

On machines where powershell is absent from PATH, this new startup branch emits a new error, optionally pauses, and exits before the normal harness/logging path, but the usual Windows CI image will not exercise that absence naturally. Without a forced HP_TEST_* hook or dedicated lane plus an NDJSON assertion for this message/exit path, this observable branch can be deleted or broken while CI stays green, just like the LF-only and probe-failure branches already noted.

Same gap, third branch: no CI test forces "PowerShell not found on PATH at all" today. Would need a hook that hides/redirects PATH resolution for powershell deterministically (harder to simulate cleanly than the other two, since it's an environment-presence check rather than a behavior override) plus a selfapps scenario.
Tracked alongside the other two in CLAUDE.md's Active Backlog Item 44 ("Known gap" note) -- all three preflight branches are called out together as the same class of deferred work, not overlooked individually.
Generated by Claude Code
Codex flagged the same missing-CI-coverage gap a third time, this round against the PowerShell-absent-from-PATH branch specifically (distinct from the PowerShell-present-but-invocation-fails branch already named). All three are the same underlying gap; the backlog note now names all three so a future pass has a complete checklist instead of two out of three.

…ll line The corrected check's negative lookbehind/lookahead regex, '(?<!\r)\n' and '\r(?!\n)', contain literal ! characters. tests/harness.ps1's batch.bang.scan does a blanket per-line scan for ! in any non-rem/ non-echo line of run_setup.bat (guarding against this repo's own delayed-expansion !-collision hazard) -- it has no awareness that these particular !s sit inside a PowerShell string nested inside a cmd.exe double-quoted argument, so it flagged the line regardless.// Confirmed as the actual CI failure via the job logs for run 31765143582 (contract-uv-fail lane): "##[error]NDJSON failures: batch.bang.scan". Since this is a static text scan (not lane-specific runtime behavior), it very likely also failed in the gating real/conda-full lanes, not just the one that happened to report first. Replaced the lookaround regex with an equivalent check using .Replace() instead: strip every CRLF pair, then confirm no bare LF or bare CR remains in what's left. Zero ! anywhere in the line now (verified via a script mirroring batch.bang.scan's own logic directly, not just reasoning that the rewrite avoids the character). Re-verified against a real PowerShell 7 binary with the exact same five cases as before (CRLF-only, LF-only, mixed, bare-CR, PowerShell-failure) -- all still pass.

run_setup.bat:run_setup.batmust function as a single bootstrapper when dropped beside the application, without requiring committed helper files.
Every branch added torun_setup.bator its related helpers must have a CI test, including feature flags, fallbacks, recovery paths, and fast/full paths.
Keep bootstrapper log messages synchronized with CI parsers; update workflow checks whenever messages or status summaries change.
All embedded helpers must remain base64-encoded under:define_helper_payloads; changing one requires synchronizing the matchingHP_*line and rerunning delimiter checks.
Do not remove tilde prefixes from runtime artifact paths such as~bootstrap.status.json,~setup.log,~environment.lock.txt, and~env.state.json.

…cy, status file
Three real, verified findings against the current preflight code, all fixed:
1. The errorlevel-2 (PowerShell-probe-failure) branch returned exit /b 1,
identical to both the PowerShell-missing branch and the invalid-line-endings
branch -- defeating the whole point of using a distinct internal errorlevel
(2) for this case. Now exits /b 2, so a caller checking the process exit
code alone (not just the console message) can also distinguish it.
2. The failure message said "Unix-style line endings (LF)" specifically, but
the check (correctly, per the earlier batch.bang.scan fix) also rejects
bare CR and mixed CRLF/LF -- a copy with one of those would get an
inaccurate diagnosis. Reworded to describe the actual, general contract
("every line ending must be CRLF") rather than the single most common
cause, while keeping the "usually happens when..." explanation as
guidance since raw download really is the realistic trigger.
3. All three preflight failure branches exit before %STATUS_FILE% is ever
set (that happens later, after cd /d) and before :write_status is safe to
call (it's call-based, and call is exactly what an LF-only copy of this
file cannot reliably do -- the whole reason this preflight avoids call/goto
in the first place). A stale ~bootstrap.status.json from an earlier
successful run in the same folder would therefore survive a failed
preflight untouched, silently misreporting state=ok to anything that
reads that file (including this repo's own test harnesses) after a run
that never got past its own first check. Fixed with a script-rooted
HP_PREFLIGHT_STATUS path (via %~dp0, reliable before cd) and a direct
JSON write (matching :write_status's own format) in each of the three
failing branches, before pause/exit.
Verified: check_delimiters.py clean, ASCII sweep clean, a script mirroring
batch.bang.scan's own logic clean, and the PowerShell command string
(unchanged by this commit) re-confirmed byte-identical to what was already
verified against a real PowerShell 7 binary.

Summary
run_setup.bat(GitHub's "Raw" button, or araw.githubusercontent.comlink) serves the file with LF-only line endings instead of the CRLF a realgit clonecheckout produces..gitattributes'stext=auto eol=lfnormalizes the stored blob to LF; the*.bat text eol=crlfoverride only affects checkout-time conversion, never what GitHub serves raw. Confirmed directly: raw download is 447,375 bytes / 0 CRLF pairs; a real checkout is 452,917 bytes / 5,542 CRLF pairs -- exactly one byte per line.goto/calllabel-seeking silently misbehaves on the LF-only copy, producing a confusing, partial, undiagnosable run instead of a clear error. This was confirmed as the actual root cause of a real Windows Sandbox debugging session (multiplepauseprompts, a PyInstaller build loop with no environment behind it, some files written and others not) -- an initial PowerShell-restriction hypothesis turned out to be a red herring for that specific sandbox.run_setup.batnow self-checks its own line endings as literally the first thing it does (before any othergoto/callin the file, so the check stays reliable even on a corrupted copy) and fails fast with a clear, actionable message instead of a silent partial run.git cloneover a raw download.docs/open-questions.mdgets a new question laying out the pro/con on fixing the distribution channel itself (.gitattributesoptions vs. a verified-CRLF release asset) for the maintainer to decide -- no unilateral change to.gitattributeswas made, since the maintainer explicitly wants diffs to stay clean and one of the options trades that away.:die-doesn't-halt cascade (split into a small "gate the repair block onHP_PYexisting" slice and a larger, explicitly NOT-small structural item), a PowerShell capability preflight gap, a confirmed false "another instance is running" lock message, a confirmed connectivity-prompt CI-safety gap, and two lower-confidence pipreqs/pyproj_depserrorlevel-handling findings each flagged with their actual verification status (one plausible-but-unverified, one confirmed-but-lower-severity-than-originally-claimed).docs/agent-cold-storage.mdgets two lower-priority, trigger-gated items (a repair-loop attempt budget cap; broader binary-presence guards beyond PowerShell).A third, independently-raised finding (a dead trailing-backslash comparison in
HP_SCRIPT_ROOT) turned out to be an exact duplicate of already-tracked Active Backlog Item 40 -- not re-filed, just corroborated.Test plan
python tools/check_delimiters.py run_setup.bat-- clean (this caught and helped fix a real bug I introduced along the way: a lone apostrophe in an echo string desynced the checker's bracket tracking)git diff --statvsorigin/main-- purely additive, no unintended changestools/run_sanity_sweep.sh-- all checks that could run in this environment passed (compileall, delimiter check, ASCII sweep, diff stat); pyflakes/yamllint/actionlint/pwsh/pytest are not installed in this sandbox and were not exercised, but none of the changed files are Python/YAML/PowerShell, so they weren't in scope for this change anyway-Commandquoting/%-pairing hazards), but has not been run against a realcmd.exe. Recommend testing by downloading this branch'srun_setup.batviaraw.githubusercontent.comon a real Windows machine and confirming the new check fires with the expected message, then confirming agit clonecheckout runs past it silently as before.Generated by Claude Code
