fix-forward #2836 (tsk-xqbcy2): add the fenced red run (S2-22 pinned-hash + set -e tests) to the PR body; no code change - #2842

📝 WalkthroughWalkthroughThe changes replace mutable installer execution with version-pinned downloads and SHA-256 verification for three catalog installations. New audit tests check URL pinning, unsafe shell piping, and checksum mismatch handling. ChangesInstaller integrity hardening
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The installer hardening improves checksum enforcement, but the current implementation can break after an upstream key rotation, permits replacement of a verified temporary installer, and does not reliably test the stated integrity guarantees. The code-server catalog metadata is also inconsistent with the installed version, so the change is not yet merge-ready. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)

Use a unique temporary file for the verified installer.
A local attacker can replace /tmp/uv-install.sh after the hash check and before sh opens it. The script performs privileged system installation, so this can execute attacker-controlled code with the installer account's privileges.
Create the file with mktemp and remove it with a cleanup trap.

Extract verified downloads that do not pipe to a shell.
This condition excludes every curl -o download. It also cannot see URLs passed to _fetch_and_verify. Therefore test_sha256_pinned_urls_are_versioned does not inspect the Deer Flow, OpenClaw, or code-server downloads that it claims to audit.
Parse direct download commands and _fetch_and_verify calls. Associate each downloaded artifact with its checksum verification before checking the URL token.

Test the production helper instead of a duplicate helper.
This test writes a new _fetch_and_verify implementation that already contains exit 1. It does not execute or inspect any installer helper. The test stays green if the Deer Flow or OpenClaw mismatch branch stops aborting.
Exercise each production helper, or extract the shared helper into a sourceable script and test that implementation directly.

CARD TITLE (intent, not commit subject): fix-forward #2836 (tsk-xqbcy2): add the fenced red run (S2-22 pinned-hash + set -e tests) to the PR body; no code change
Autonomous build of board card tsk-amlz57.
REVISION: built on
exec/tsk-xqbcy2(cut at2319e26d93eee075aad9e738525ef352409e30d8), not ondev. That branch'scommits are ancestors of this one. Verified by
git merge-base --is-ancestorbefore the PR was opened.
Supersedes #2836. The merge gate for S2-22 (RED-FIRST) requires a fenced
block showing the checker/test FAILING before the fix. PR #2836 carried
prose ("RED test: ...", "Red-forward:") but no fenced failing run.
BASE: exec/tsk-xqbcy2 (commit 2319e26, fix already applied).
Zero source/test-file diff versus BASE; this commit only carries the
red-then-green evidence in the body (commit body becomes the PR body).
Red run: scratch worktree on origin/dev (installer scripts un-fixed),
with ONLY tests/scripts/test_audit_s2_22.py checked out from BASE:
Green run (on BASE exec/tsk-xqbcy2, fix applied - download-then-execute with
sha256sum -c && chain and version-pinned URLs):
Closes #2836.
