aura-engine is documented (C16) and named as the reusable, domain-agnostic reactive SoA substrate, yet `report.rs` concentrated the trading-domain analysis layer inside it. This cycle relocates the pure-domain leaf into a new `aura-analysis` crate (deps: aura-core + serde only), erecting the engine/domain seam before the Stage-2 broker milestone deposits more currency/position-event code into the same module. Behaviour-preserving (C1): the full workspace suite stays green unchanged (665 passed), including the C18 on-disk byte-identity goldens (cli_run, the registry legacy-line loads). Moved to aura-analysis (bodies verbatim — no float expression re-associated): RunMetrics, RMetrics (+ its hand-written PartialEq), the private r_col column indices + SQN_CAP, summarize_r, r_metrics_from_rs, derive_position_events, PositionAction (+ From/TryFrom<i64>), PositionEvent, and the deflation stats helpers inv_norm_cdf / expected_max_of_normals. Their unit tests and private helpers (r_row / r_row_full / pm_row) relocate with them — tests live with their subject (the r_col helpers reach the private module directly, which a re-export cannot bridge). Stays in aura-engine for this cycle: the generic trace plumbing (ColumnarTrace, join_on_ts, JoinedRow, f64_field), RunManifest, RunReport, and summarize (it bridges recorded trace columns into RunMetrics, so it is trace-coupled). The mis-placed orchestration types FamilySelection / SelectionMode also stay (their relocation is entangled with the registry-vocabulary fork, deferred). report.rs pub-re-exports the moved symbols, so aura-engine's lib.rs re-export block and every `crate::report::X` / `aura_engine::X` consumer (aura-registry, aura-cli, aura-composites, aura-ingest) compile byte-unchanged; only the new crate, the workspace member list, aura-engine's Cargo.toml dep, and report.rs itself change. Deferred to later cycles (genuine design forks, route through specify when reached): making RunReport generic over a metric type M and re-bounding sweep/mc/walkforward; relocating the aura-registry Metric / metric_cmp / rank vocabulary; relocating FamilySelection / SelectionMode. Fork decisions logged on #136.
