The shell no longer defines what an aura backtest is. Tasks 1-9 of the shell-boundary cycle — structural extraction, behaviour byte-identical: - aura-runner (new; the C28 assembly position): input binding (the C26 module, moved whole), the C1-load-bearing param<->config translators, harness assembly (wrap_r / run_signal_r / run_blueprint_member and the probe/reopen cluster), axis + risk-regime conventions (bind_axes et al.), the campaign family builders + MC guards, reproduce (process::exit -> RunnerError, shell remaps to identical bytes), the measurement-run orchestration, project loading (Env / cdylib load / charter / staleness, moved whole), the coverage gap-walk (deduplicated onto interior_gap_months), and DefaultMemberRunner — the public implementation of aura_campaign::MemberRunner (ex CliMemberRunner). The MemberRunner trait stays in aura-campaign; the column still imports no harness/data-binding machinery. - aura-measurement (new; seeds C28 rung 3): the IcMetrics/IcKey vocabulary + information_coefficient, verbatim incl. serde derives (#294 duplicate-timestamp semantics move as-is, unresolved). - aura-backtest: the pure per-run scaffold (point_from_params, wf_ms_sizes / fit_wf_ms_sizes, intersect_shared_window). - shell residue: main.rs / campaign_run.rs keep argv/dispatch, argv->document translation, and presentation only; walkforward_summary_json_from_reports now calls the public aura_engine::param_stability instead of its inline twin. - worked example (crates/aura-runner/examples/world_member_run.rs): a World program runs a member backtest through the library alone. Held quality findings, adjudicated: the plan's literal pub-visibility list for binding.rs kept (cosmetic); ~20 refusal sites inside aura-runner (family/member/measure/translate) still process::exit — behaviour-identical today, conversion to RunnerError is filed forward (refs #297); rustfmt line-width drift on re-pathed call sites left for a repo-wide fmt decision. Verification: cargo test --workspace green (1471 passed, 0 failed); cargo clippy --workspace --all-targets -D warnings clean. Byte-identity is pinned by the untouched shell E2E suites (cli_run, measure_ic, run_measurement, research_docs, run_refuses_unrunnable_blueprint, tap_recording — zero assertion edits). Remaining in this cycle: full-workspace c28_layering + shell-content check, ledger amendments (C28 assembly position, C25/C14 control-surface consequence, C26 realization note). refs #295
