Core insight: most durable, costly lock‑ins begin as invisible consumer bindings—automations, dashboards, partner contracts, or habit‑driven workflows that silently adopt a decision. The Commitment Echo is a tiny operating primitive you run before any non‑trivial commit: publish an Echo Token (decision id | owner | effect | sunset | rollback primitive) into machine and human channels where likely consumers live, run an automatic consumer discovery sweep, and require an explicit machine or human acknowledgement within a short window. This episode gives three concrete echo channels (code/contracts, dashboards/agents, stakeholder feeds), two constrained AI patterns to enumerate and message probable consumers with provenance, and a strict enforcement rule: no irreversible binding until acknowledgements meet a simple quorum or a documented shadow period elapses. Outcome: fewer surprise cascades, clearer ownership of bindings, and cheaper reversions. Fast action: publish an Echo Token for one imminent decision and collect the first acknowledgements within 48 hours. CTA: subscribe.
