What changes

Repair two shared CI blockers after #7000 became selected. The CI guide now points to the current replay and retains #6030 as history. The historical selected-check audit now runs against its inspected commit instead of comparing later live Makefile/docs bytes with old pins.

The historical repair reuses Clear1nsight's #7257. All retained source hashes and the 19 rejections, seven paths, nine-package plan and empty-diff control are preserved. Fresh-checkout and corruption regressions accompany it. Credit unpaidmoon for the original audit and the retained replay/planner authors. The navigation repair follows #7161 and ToikY's f2206e6; this PR isolates the maintenance work from their research submissions.

Checks

• ["python", "-B", "-m", "unittest", "discover", "-s", "tests", "-p", "test_research_historical_snapshot.py"]: passed (exit 0). unittest: 4 tests run; 0 failures; 0 errors; 0 skipped; 0 expected failures; 0 unexpected successes.
• ["python", "-B", "-m", "unittest", "discover", "-s", "tests", "-p", "test_research_current_status.py"]: passed (exit 0). unittest: 6 tests run; 0 failures; 0 errors; 0 skipped; 0 expected failures; 0 unexpected successes.
• ["python", "-B", "scripts/research_package.py", "--package", "research/historical-selected-replay-gap"]: passed (exit 0).

Not tested

Updated-head hosted CI is pending. No selected-family scientific cold replay or supplier proof is claimed. At original head a54cd49, the full native onboarding run had 11 failures, 23 errors and 90 skips across 760 tests; seven representative failures also reproduce with unchanged main. Those native fixture/platform issues remain unrepaired, and the full native suite is not rerun for this scoped update. Fresh historical checkouts are generated from retained Git objects, not freshly acquired over the network.
