Replace the monolithic mutable runtime with a coordinator-claimed six-stage immutable aggregation prefix. Derive each evaluator frontier and input packet only from the committed predecessor stage, bind every manifest to the static lock, coordinator, predecessor, and cumulative envelopes, and rederive the chain during bound-gate evaluation. Make attempt sealing bounded and crash-recoverable with exact external workspaces, seal-time input verification, injective pathname capture, hard payload, entry, and path budgets, immutable terminal claims, and no-replace object and pointer publication. Publish authenticated terminal ERROR records when a phase cannot safely derive its successor while allowing usable report-format failures to reach their frozen gate consequence. Update schemas, policies, integration contracts, and adversarial self-tests for the 154-to-163-attempt, six-stage production lifecycle. gherrit-pr-id: Gfkyot5qmode4aiscnrbgzyffxebq4z56 Agent-Authored-By: AI agent acting on Josh Liebow-Feeser's behalf
