Problem

packages/runtime-host/src/desktop-e2e-execution-candidate-main.ts is a second copy of the real candidate startup (execution-candidate-main.ts), forked only for Desktop E2E. It re-implements startup with a FakeBackend subclass, hardcoded OAuth stubs, bootstrapRuntimePolicy: false, and idleGraceMs: 500, and is selected by module name at apps/desktop/src/main/runtime-host-boot.ts:501 under MAKA_E2E=1.

It is a fork of a lifecycle authority that must be hand-synced and has already drifted (it lacks the real main's startup-failure classification and policy bootstrap). The real main already accepts composition overrides, so the fork is avoidable.

Desired outcome

One candidate entrypoint with an E2E composition/flag override. Desktop E2E keeps its deterministic backend; production startup is unchanged.

Alternatives or workarounds

Keep the fork and continue hand-syncing two copies of the same startup path.

Acceptance

  • desktop-e2e-execution-candidate-main.ts and its package subpath export are removed
  • runtime-host-boot.ts selects the single candidate main with an E2E override (flag or composition), not a separate module
  • Desktop E2E still gets its deterministic FakeBackend backend
  • Desktop E2E fixtures pass; runtime-host and desktop build/typecheck pass

                          Problem
                          packages/runtime-host/src/desktop-e2e-execution-candidate-main.ts is a second copy of the real candidate startup (execution-candidate-main.ts), forked only for Desktop E2E. It re-implements startup with a FakeBackend subclass, hardcoded OAuth stubs, bootstrapRuntimePolicy: false, and idleGraceMs: 500, and is selected by module name at apps/desktop/src/main/runtime-host-boot.ts:501 under MAKA_E2E=1.
                          It is a fork of a lifecycle authority that must be hand-synced and has already drifted (it lacks the real main's startup-failure classification and policy bootstrap). The real main already accepts composition overrides, so the fork is avoidable.
                          Desired outcome
                          One candidate entrypoint with an E2E composition/flag override. Desktop E2E keeps its deterministic backend; production startup is unchanged.
                          Alternatives or workarounds
                          Keep the fork and continue hand-syncing two copies of the same startup path.
