DORA Escalation Demo Chain

Note (dated 2026-08-04): a chain composes independent computations performed in an analytical order. No step's output is carried into the next step by the execution model; each step computes from its own declared inputs. This is true of every chain on this site, including chains whose per-step copy below reads as a data handoff.

Demonstrates OCG §22.8.2 escalation EMIT/HALT semantics. DORA Readiness Diagnostic runs first: a grade F triggers the escalate gate, halts the chain, and opens an escalation record. A passing grade routes forward to DORA Incident Classifier.

§22.8 Escalation EMIT/HALT

When the gate fires escalate, the run halts immediately. Remaining steps are marked skipped_by_escalation (distinct from skipped_by_gate). An open escalation record is emitted with a deterministic record_hash over { decision, halted_steps }; opened_at is excluded from the preimage so the hash is stable across runs. The composite execution hash is computed over ran steps only, before the escalation record is attached.
