Promise-Held Ledger for SaaS support directors

A pre-send gate and post-resolution ledger for the customer-facing date commitments support agents make every day ("fixed by Friday", "response within 48 hours"). It plugs into Zendesk/Intercom, watches outbound replies for commitment phrases, and the moment an agent drafts one shows the historical resolution-within-window rate by category, agent, and customer tier. After the ticket resolves, it grades the promise against the actual close timestamp. Over weeks it builds a per-agent and per-category miss-pattern ledger the support director uses for coaching, SLA forecasting, and honest external promise-setting. Built for support directors at 50-500 person SaaS who own CSAT and SLA breach numbers and hold direct budget. AE's adversarial multi-model debate and the structured constraint language with promotion/demotion lifecycle map cleanly onto graded commitments with explicit promise-state transitions; the under-24h grading loop matches ticket resolution rhythm. Truth is the Zendesk close timestamp — no rubric interpretation, only date strings and statuses leave the buyer's tenant.

Promise-Held Ledger is the rare hypothesis where AE's reality-graded, lifecycle-aware substrate has a one-to-one mapping onto a buyer who owns the budget, feels the pain daily, and lives inside a system (Zendesk) that already emits the ground-truth signal.
