Event titles can currently be saved and treated as approved without checking casing, whether they name a topic, or whether the episode/Card/hold copies agree.

Add dataops event title-check for existing events or a proposed title, and dataops event approve-title to record an operator review of the exact title. Deterministic checks explain Title Case, draft/TBD and guest-only placeholders; breadth uses an explicit meaningful/broad/consistent checklist with the owner's narrow-topic example as a warning. Approval requires a review note, all three confirmations, matching stored copies and the current Card version. Changed titles invalidate approval. Document and public copies are explicitly included in the operator's consistency review; the checker never changes or publishes them.

Save responses for Cards, episodes and holds expose actionable diagnostics, which the CLI also prints. Title-dependent Tasks can require the review through validation.titleQuality: "topic-approval" or "publication". Calendar approval remains the scheduling action, so first-contact invitations and calendar acceptance receive no new topic-preview gate. No templates, SOPs, existing event titles or external services are changed by the check/review actions.

A separate focused CI commit reuses the agreed fix from PR #400: select the direct Ubuntu archive before the unchanged Playwright dependency installation. The previous exact-head browser run failed before tests because the runner's Azure mirror could not resolve. Browser assertions and test steps are unchanged.

Validation: backend typecheck; targeted event title, lifecycle service, podcast episode and calendar hold tests (35 unique tests); CLI title-check/review tests. Covers all event types, spelling exceptions, drafts, review CAS/staleness, confirmed title-copy drift, save diagnostics and configured Task completion.
