// Why: the telemetry transport is gated by two compile-time constants that

// only the official CI release workflow sets. Contributor / `pnpm dev` /

// third-party rebuilds must substitute literal `null` at these sites so

// `IS_OFFICIAL_BUILD` in `src/main/telemetry/client.ts` evaluates `false`

// at module load and the track() wrapper short-circuits to console-mirror.

// The substitution happens at compile time — there is no runtime env-var

// fallback — so a curious contributor cannot spoof transmission with a

// shell export.

//

// CI injects real values via GitHub Actions secrets

// (ORCA_BUILD_IDENTITY='stable' | 'rc', ORCA_POSTHOG_WRITE_KEY=phc_...);

// every other build path resolves these env vars to undefined, which the

// JSON.stringify below folds to the literal `null`. Ambient declarations

// for the two constants live in `src/types/build-constants.d.ts`.
