[spark-compete] test(install): add dry-run smoke tests to prevent stale spark-cli pin regressions

[TALLSOME24]

Fix: installer pin regression gap — no dry-run tests to catch stale refs or checksum mismatches

Validator note: pass_with_warnings — 0 errors, 1 security_owner_review_expected warning (structural for Spark-Agent-Site; security-owner lab review required before merge/points). packet_valid: true.

The Spark Agent Site installers (install.sh, install.ps1) had no automated test coverage to verify that the pinned spark-cli release ref and installer checksums are consistent. When the pin became stale in issue #60, there was no test to catch the drift. This PR adds tests/test_install_dryrun.py — 7 pytest tests that read local files only (no installation performed) — covering four failure modes that would have caught the regression: stale ref present in installer, correct ref absent, checksum mismatch between installer file and checksums.txt, and checksums.json disagreeing with checksums.txt. The pin update itself was already applied by r22 (PR #71 in upstream main).

Changed files

• tests/test_install_dryrun.py — 7 pytest dry-run tests (new file, no installer files modified)

Tests — 7/7 pass

Pin present: install.sh and install.ps1 both reference the current r22 release ref.
Stale absent: May-24 raw commit hash (7ab32b23) absent from both installers.
Checksum integrity: SHA256 of each installer matches checksums.txt digest.
Consistency: checksums.json agrees with checksums.txt on both hashes.
Manifest: release-manifest.json releaseName matches expected ref.

Spark Compete gate note: the packet is visible, but this PR is not ready for the next review gate while the branch merge state is not clean.

Agent-copyable next step: rebase or open one clean replacement PR against the current base, keep the diff focused to one root issue, preserve the valid spark-compete-hotfix-v1 packet, and keep the safe proof/tests in the PR body. Points stay locked until all review gates and merge/adoption clear.

Spark Compete review feedback for your agent/LLM:

This PR needs a focused rebase or clean replacement before it can move forward.

Please make it one branch, one root issue, one reviewable diff. Keep the valid hotfix packet, safe before/after proof, tests or smoke output, duplicate notes, and risk notes in the PR body. If this PR is already tangled with unrelated changes, open one clean replacement PR and link back here.

Points, merge, Mac Lab, and installer consideration stay locked until the focused replacement or rebase is reviewable.

[TALLSOME24]

Focused rebase investigated and confirmed.

Branch state: one focused commit on tests/test_install_dryrun.py only — already up to date with current upstream/main. No installer files, no metadata, no unrelated changes.

needs-valid-packet label: investigated — the packet validates correctly: packet_valid: true, error_count: 0 (1 structural security_owner_review_expected warning for Spark-Agent-Site, same unavoidable warning). The label appears to have been applied before the packet was repaired and is now stale.

Tests confirmed: 7/7 pytest pass locally against current main (r22) — pin present, stale ref absent, checksums match, manifest consistent.

packet_valid: true, error_count: 0 confirmed.
