require both an `@claude` mention and the GitHub pull-request discriminator on
issue_comment events. Preserve the existing comment-body check while adding

- Around line 247-253: Update the diagnostic flow around the od/head pipeline so
the human-readable sanitize-echo reason is emitted first and the hex dump
remains the final value detail. Prevent SIGPIPE or pipefail from propagating to
the caller when truncating output at STRINGS_BSH_REPORT_MAX, while preserving
the existing byte-oriented, capped hex representation.
- Around line 211-216: Add an argument-presence guard at the start of
validate_safe_filename before expanding "$1", matching the sibling validators’
behavior: emit the established missing-name error and return 1 when no variable
name is supplied, while preserving the existing validation flow for provided

…llback CodeQL on PR #78: 1 high (py/tarslip) + 1 note (py/unused-import), both in this file, which arrived via the merge of #69. extractall(filter="data") is safe, but the 'except TypeError' fallback for interpreters predating that argument extracted with NO validation at all, so a member named '../x' or an absolute path escaped the temporary directory. The fallback now validates every member: the resolved path must stay inside the destination, and a link member is refused outright -- an OVA is a flat archive of .ovf/.vmdk/.mf files, so a link is never legitimate. Verified each hostile member type is refused ('../escaped.txt', '/abs.txt', and a symlink to /etc/passwd) and that a benign archive still yields its members. Also drops the unused 'sys' import. Co-Authored-By: Claude <noreply@anthropic.com>
Three of four taken. validate_safe_filename now rejects a missing argument, like its two siblings. It expanded "$1" unguarded, so a no-argument call aborted the caller with '$1: unbound variable' under nounset instead of returning 1. Reproduced. The hex dump moves AFTER the human-readable reason. It was printed first, which contradicts the reason-FIRST/value-LAST contract documented at the top of the file and buried the explanation under hex digits. consumer-claude-code.yml: - the concurrency group gains an '@claude' term. Concurrency is evaluated BEFORE the job-level 'if:', so an unrelated comment on the same PR joined the group of an in-flight review and cancelled it, while its own job was then skipped. - the job now requires a pull-request context. 'issue_comment' fires for ISSUES too, and an issue carries no PR for the reviewer to check out. Written as an alternation because github.event.issue.pull_request is absent for pull_request_review_comment, which is always a PR. NOT taken: the SIGPIPE half of the od|head finding. Not reproducible -- with a 200 KB value the pipeline still reports PIPESTATUS=(0 0) under pipefail, because GNU head --bytes drains its input rather than closing the pipe early. The ordering half of that same finding is fixed above. Co-Authored-By: Claude <noreply@anthropic.com>

Header-phase curl_prgrs_content_length is expected_header_size (an estimate); enforce_final_size ran it as a hard ceiling, failing a legitimate large-header response (long redirects, big Set-Cookie) of 8001..32000 bytes with 114. Enforce only maximum_http_header_size there; the body phase keeps the advertised length.
- Match software markers (llvmpipe/swrast/"Software Renderer"/"Basic Render Driver") before the vendor list, and vendor tokens whole-word: else "Apple Software Renderer", WARP D3D12 and "ATI" inside "NATIVE" read as accelerated. - LIBGL_ALWAYS_SOFTWARE is Mesa-only; do not short-circuit to software when an NVIDIA node is present (NVIDIA ignores it) -- probe the real renderer instead.

LIBGL_ALWAYS_SOFTWARE is a deliberate user/admin directive (nothing in the OS sets it); honor the intent regardless of driver -- report software without probing. Matches the consumer (forces software QML) and is crash-safe.
Pull the header-vs-body content-length ceiling selection out of curl_download into content_length_ceiling_for_phase, so it is source-able and formally verifiable (dist-ai T4). Behavior-preserving.
