fix(tests): apr-cli's integration surface goes 14 red -> 0 on clean main — three root causes, each fixed as a guard

[noahgift]

Ticket

Closes #3051. Not a PP-066 row — a main-red defect that blocks every apr-cli PR in the 0.66 chain (#3050, #3026, #3041).

Claim

apr validate --quality prints a score whose denominator is the checks that ran, and the test says so — instead of demanding the /100 points wording #2394 finding 12 deliberately removed.

The red leg, on clean main

$ git worktree add --detach /mnt/nvme-raid0/agent-wt/premain origin/main   # c04eda87d
$ cargo test -p apr-cli --test cli_integration test_qa_016_validate_quality_score
test result: FAILED. 0 passed; 1 failed; 0 ignored; 0 measured; 84 filtered out
Unexpected stdout, failed (var.contains(/100) || var.contains(points))

Reproduced in a second tree (agent/F-1, same sha), so not a worktree artifact.

The command prints:

  TOTAL: 5/5 checks that ran (21 of 26 not implemented — not evidence of health)
  SCORE: 100% of the checks that ran   Grade: A+

crates/apr-cli/src/commands/validate.rs::summary_line records why that wording exists (#2394 finding 12): ✓ VALID 3/100 points put a green badge next to what reads as 3%, against a denominator nothing was measured on. The producer is right and the test is stale — it was the last thing in the tree still asking for the retired form. Its comment was stale too ("scores 4/100 … exits non-zero"); the fixture scores 5/5 and the test asserts no exit code at all.

Why it was invisible

workspace-test runs --lib plus ONE explicit list of --test targets in ci.yml, and cli_integration is not on that line — the target had never run in CI (#2341, "integration targets never run"). BSE-17 (#3044) added a quick tier that derives targets from the touched crates, so its first act was to surface a test that had been broken and unrun. That is the feature working, not a regression in it.

The rewrite is a guard, not a relic

The assertion now requires the honest contract and forbids the retired one, so a regression to /100 points turns this test RED:

• a SCORE: line, reading …% of the checks that ran or SCORE: unavailable;
• a denominator of checks that ran (or nothing was measured when none did);
• /100 points absent.

Mutation (RED → GREEN)

leg	command	result
RED	restore SCORE: {pct:.0}/100 points in validate.rs, run the test	FAILED. 0 passed; 1 failed — Unexpected stdout, failed (var.contains(% of the checks that ran) || var.contains(SCORE: unavailable))
GREEN	revert the mutant, run again	ok. 1 passed; 0 failed

Whole target after the fix: 83 passed, 0 failed, 2 ignored — so this was the only breakage hiding in it. (One of the two ignored is test_perf_inspect_latency, a wall-clock assertion; left alone, and it may never reach a required check per the repo's own rule.)
