fix(review): treat an empty consent phrase as unconfigured, not auto-satisfied

[luciferlive112116]

Summary

Closes #5838

evaluateClaCheck (src/review/cla-check.ts) computed phraseSatisfied = config.consentPhrase !== null && (ctx.body ?? "").toLowerCase().includes(config.consentPhrase.toLowerCase()). When consentPhrase is the empty string "" (distinct from null — claConsentPhrase is a dashboard/API-settable z.string().nullable() field), "" !== null is true and any body.includes("") is unconditionally true, so phraseSatisfied was always true — silently satisfying CLA consent for every PR, even one whose configured CLA check-run was failing.

Fix: normalize an empty consentPhrase to null at the top of the function, so it is treated as "phrase detection not configured" (the same as null) — it never satisfies consent, and never emits a nonsensical the PR description must contain "" requirement. This matches the field's documented contract ("null ⇒ phrase-match detection is not configured").

Scope

• Conventional Commit title (fix(review): …).
• Focused: one-function correctness fix + regression tests.
• Follows CONTRIBUTING.md; no site//CNAME/VitePress.
• Linked open issue (Closes fix(review): evaluateClaCheck treats an empty-string consentPhrase as unconditionally satisfied #5838, above).

Validation

• git diff --check
• npm run typecheck clean
• npm run test:coverage on src/review/cla-check.ts: 100% lines & branches (25/25) — the new empty-vs-non-empty normalization branch is covered by the added tests; existing tests cover the null/non-empty paths.
• Regression tests: an empty phrase + a failing check-run now hard-fails (cla_consent_missing) listing only the check-run (never must contain ""); an empty phrase with no other method configured is "nothing configured" → no finding.

If any required check was skipped, explain why:

• Full test:ci not run end-to-end locally (Linux-only shell/self-host steps on Windows); the change-relevant gates (typecheck, focused coverage, the cla-check suite) were validated directly.

Safety

• No secrets, wallets, hotkeys, trust scores, rewards, private rankings, or private maintainer evidence. This tightens a consent bypass (fails safe: an empty phrase no longer auto-satisfies CLA).
• No auth/cookie/CORS/GitHub App/session change (pure evaluator over caller-supplied data).
• No API/OpenAPI/MCP behavior change.
• No UI changes; no changelog edit.

Review summary
This fixes a real bug: an empty-string consentPhrase (distinct from null) previously satisfied CLA consent for every PR because `body.includes("")` is always true, silently bypassing an intentionally-configured failing check-run. The fix normalizes empty string to null at the top of `evaluateClaCheck`, treating it as unconfigured, and updates both the `phraseSatisfied` computation and the missing-methods message to use the normalized value. The added regression tests directly exercise the two previously-broken paths (empty phrase + failing check-run now hard-fails without the check-run; empty phrase alone with nothing else configured now correctly returns no finding).

Nits — 4 non-blocking

• src/review/cla-check.ts: the comment block is fairly verbose for a one-line normalization; could be trimmed to a single sentence per repo convention elsewhere in the file.
• Consider also normalizing empty-string `checkRunName` the same way if that field has the same nullable-string contract, to preempt an analogous bug (verify in src/review/cla-check.ts config type).
• Pull request duplicates other open work — Check for an existing pull request or issue covering this change and coordinate or consolidate before continuing.
• Readiness score is below the configured threshold — Use the readiness panel as advisory maintainer context; the score does not block this PR.

Improvement	✅ Minor	risk: low · value: minor — Code changes are accompanied by test evidence.

Linked issue satisfaction

Partially addressed
The diff correctly normalizes an empty-string consentPhrase to null and adds a solid regression test for that case, but it does not use `.trim()` to also normalize whitespace-only strings (e.g. " ") as the issue explicitly requires, and the required regression test for the whitespace-only case is missing.

Review context

• Role context: outside_contributor
• Public audience mode: oss maintainer
• Lane context: Repository registration is not available in the local Gittensory cache.

Contributor next steps

• Compare fix(review): treat a blank consentPhrase as unset in evaluateClaCheck #5877.
• Add a concise scope and risk note.
• Await review-lane availability.
• Triage stale or unlinked PRs.
• Refresh registry data or choose a registered active repo.
• Check active issues and PRs before submitting.

Signal definitions

• Related work = same linked issue, overlapping active PRs, or title/path similarity.
• Change scope = cached public metadata such as size labels, draft state, and review-burden hints.
• Validation posture = whether the PR provides enough public validation/test evidence for maintainer review.
• Contributor workload = public contributor activity and cleanup pressure, not a repo-wide quality failure.
• Contributor context = public GitHub/Gittensor identity context; non-Gittensor status is not a blocker.
