Subject: [PATCH 1/3] feat(review): add cached repo quality-culture profile as
AI-review grounding (#2995)
Derives a deterministic per-repo signal (typical merged-PR size, common
accepted labels, description-length norms) from recent_merged_pull_requests
and caches it via signal_snapshots with TTL + merged-PR-count invalidation,
mirroring the focus-manifest cache pattern. Wired additively into the AI
reviewer's user prompt alongside RAG/grounding (review/repo-culture-profile*
.ts), gated by the GITTENSORY_REVIEW_CULTURE_PROFILE env flag and the new
review.culture_profile .gittensory.yml opt-in -- both default off, so the
change is byte-identical until deliberately enabled. Never a gate/scoring
input; degrades silently to no context on sparse history or any error.
Validated: npm run typecheck, npx vitest run on the new + touched test
files, and the affected regression suites (queue, ai-review-cache,
focus-manifest, signals-coverage) all green with 100% branch coverage on
the two new modules.

Subject: [PATCH 2/3] fix(review): neutralize prompt-injection in
culture-profile labels, close 2 coverage gaps
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Superagent (P3): entry.label in formatRepoCultureProfileSection came
straight from user-controlled GitHub label text on merged PRs, with no
sanitization before it reached the AI reviewer prompt. Neutralize it
through the existing prompt-injection defense (neutralizePromptInjection),
the same way safeReviewTitle already protects an untrusted PR title.
Also closes 2 partial-branch codecov/patch gaps: focus-manifest.ts's
reviewConfigToJson had no round-trip test for review.culture_profile
(mirrors every sibling boolean flag's existing test), and
processors.ts's dynamicReviewFeatures.cultureProfile — unlike its
env-only siblings (grounding/rag/enrichment/reputation) — is dual-gated
by both the global env flag AND the per-repo manifest opt-in, so no
existing test drove both true through a real webhook.
