/**
* Conductor → prose decision brief (periodic-tier, paid, real-PTY).
*
* Proves the end-to-end behavior: when CONDUCTOR_SESSION is signalled, a skill
* that hits a decision renders a PROSE decision brief and waits, instead of
* silently skipping the user.
*
* SCOPE — read before trusting this as the Conductor guard. This is END-TO-END
* BEHAVIOR coverage, NOT the discriminating Conductor guarantee:
* - The deterministic guard is test/question-preference-hook.test.ts
* ("Conductor prose redirect") — it sets process.env.CONDUCTOR_* and asserts
* the PreToolUse hook denies + redirects. That test CAN fail on unfixed code.
* - The PTY harness here cannot register `mcp__conductor__AskUserQuestion`, so
* it tests "native AUQ unavailable + Conductor signal → prose," NOT "the MCP
* variant exists and must not be called" (Codex #10). Under --disallowedTools
* a present-human interactive session already prose-falls-back, so this test
* is a smoke check that the Conductor path still produces a prose brief, not
* a proof that the Conductor signal (vs the generic fallback) drove it.
*
* Periodic tier: model-behavior, non-deterministic.

## Goal
Increase developer adoption.
## Premise
No tests mentioned, no rollout plan, no auth check on the upgrade endpoint.
Adds a Stripe tier, a React pricing page, a Postgres entitlements table, and a
Redis cache. The team "feels like" it should be cheaper; no developer was asked.
