The open build already treated analytics and tracing as inert, but several empty sink and shutdown modules still made startup and exit paths look like they initialized or flushed telemetry. This trims those dead compatibility layers, updates the surrounding comments to match reality, and adds small regression tests that lock in the inert analytics boundary and disabled transcript sharing behavior.
Constraint: Preserve the no-op logEvent/logOTelEvent compatibility surface for existing call sites
Constraint: Avoid touching unrelated bridge and session work already in progress in the worktree
Rejected: Remove every remaining logEvent/logOTelEvent call site | Too broad for a safe first cleanup pass
Rejected: Keep the empty sink/shutdown modules | Continued to mislead future audits and maintenance
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Treat remaining analytics and GrowthBook helpers as compatibility surfaces until each call path is individually proven dead
Tested: bun test src/services/analytics/index.test.ts src/components/FeedbackSurvey/submitTranscriptShare.test.ts
Tested: bun run ./scripts/build.ts
Not-tested: bun x tsc --noEmit (repository has pre-existing unrelated type errors)
