Prove total orders with Kahn traversal and use ranks; stream forward and reverse reachability for general partial orders instead of retaining every closure. Aggregate unordered conflicts by declaration while preserving missing-pair counts and independent malformed-input diagnostics.
Validation: 33 focused trace domain and CLI/MCP boundary tests passed. Six bounded Flameox executions preserved answer digests and cycle rejection; combined median peak RSS fell from 391.13 to 127.72 MiB. General partial-order traversal costs more CPU; the experiment records that tradeoff. Full suite and real-provider lanes were not run.
Use iterative cycle detection, memoized reachability and compact unordered-group membership. Preserve declaration diagnostics on cyclic input while skipping checks requiring a valid partial order. Report duplicate group declarations once instead of repeating pair errors.
Replace redundant source cycle/missing-pair assertions with public CLI/MCP coverage including 6000 events, dense not-before constraints and a large unordered group. Validate acyclic branching and mixed relation semantics. Document bounded Flameox CPU/latency gains and higher observed peak memory; agent/model costs remain unmeasured.
Summarize incomplete trace-specification pair declarations with exact counts and the first undeclared pair. Preserve complete pair coverage, successful Evidence and independent validation errors; remove temporary pair-scan copies and sorting.
Closes#1753.
