fix(review): treat a blank consentPhrase as unset in evaluateClaCheck

[lourincedaging0-commits]

Closes #5838. Gate-bypass fix in evaluateClaCheck.

An empty-string consentPhrase (distinct from null/unset) makes "".includes("") unconditionally true, so phrase detection silently satisfies CLA consent for every PR. Reachable via the dashboard/API-settable claConsentPhrase (z.string().nullable().optional(), no non-empty validation); ?? null at the call site only substitutes for undefined/null, not "".

Fix: normalize a blank/whitespace-only consentPhrase to null once at the top of evaluateClaCheck, used at all three sites — mirroring the config-as-code path (focus-manifest normalizeOptionalString). Applied identically to both hand-duplicated twins (src/review/cla-check.ts and packages/loopover-engine/src/review/cla-check.ts) so the engine-parity check stays green. Scoped strictly to consentPhrase normalization — the escalation/severity contract and either-method-holds logic are untouched.

Regression tests for consentPhrase: "" and " " in both the host suite and the engine-copy suite (predicted-gate-engine-coverage.test.ts). Verified locally: engine-parity test 38/38, 100% branch coverage on both twins, tsc --noEmit clean.

Review summary
This fixes a real gate-bypass: a blank/whitespace-only consentPhrase previously made "".includes("") unconditionally true, silently satisfying CLA consent for every PR. The fix normalizes consentPhrase to null at the top of evaluateClaCheck and threads the normalized value through all three usage sites (early-return check, phraseSatisfied, and the missing-methods message), applied identically to both hand-duplicated twins to keep engine-parity green. Tests cover empty-string, whitespace-only, and a non-empty regression case in both the host and engine-copy suites, and the fix is scoped strictly to consentPhrase normalization without touching the escalation/severity contract.

Nits — 6 non-blocking

• cla-check.ts: consider extracting the normalization (`consentPhrase.trim() !== ""`) into a small shared helper (or the same normalizeOptionalString referenced from the focus-manifest path) rather than duplicating the ternary logic across two hand-copied files, to reduce future engine-parity drift risk.
• The PR duplicates the exact same fix and comment verbatim across src/review/cla-check.ts and packages/loopover-engine/src/review/cla-check.ts — worth a one-line note in the PR description on why these can't be unified (if that's a known repo constraint).
• Consider adding a shared normalizeOptionalString-style utility used by both cla-check.ts twins and the focus-manifest path, to guarantee this class of blank-string bug can't recur elsewhere.
• The comment block in both files is fairly long (3 lines) — could be trimmed to the single sentence explaining the '"".includes("")' hazard for conciseness.
• 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.

Linked issue satisfaction

Addressed
The diff normalizes a blank/whitespace-only consentPhrase to null in both cla-check.ts copies before the phraseSatisfied check, exactly matching the requested fix, and adds regression tests for empty-string, whitespace-only, and non-empty consentPhrase behavior in both test suites.

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.
