cycle 0096 tidy (clean). Architect drift review over ebebc24..HEAD: no drift, no debt. Regression: no dedicated script (architect is the sole gate); its "What holds" is non-empty (design commitments confirmed against the diff + a green test run, not the commit body): - Inv. 8 / 9: the cycle touches only crates/aura-cli (main.rs + cli_run.rs + the ephemeral spec/plan) — no engine/registry/blueprint.rs change; those are read-only callees. - Inv. 1: --list-axes is a pure read-only probe (short-circuits before run_blueprint_sweep; builds the wrapped composite, reads param_space, prints — no run, no seed, no engine execution). - Behaviour-preserving single-source: blueprint_axis_probe is token-identical to the two former inline probes; three copies (sweep/mc/list) collapse to one; the reload closures survive (topology_hash + per-member run); clippy -D warnings clean, no dead code; the subsumed tests (blueprint_sweep_member_equals_single_run_and_shares_topology_hash, blueprint_mc_family_rejects_an_open_blueprint) stayed green. - The blueprint_axis_probe .expect is not a latent panic: the ["sweep",..] arm validates blueprint_from_json first (exit 2), pinned by the shipped aura_sweep_list_axes_rejects_malformed_blueprint E2E (no panic). Ledger: refreshed the C24 realization block (docs/design/INDEX.md) — reclassified the "axis-name discovery surface" from tracked debt to shipped (cycle 0096), recording the single-sourced blueprint_axis_probe and the listed==swept-by- construction property. Per-member trace-writing (#168) remains the one tracked debt in that block. Milestone World/C21 stays OPEN — the walk-forward half (#173, IS-refit, now unblocked by this #169) remains. Ephemeral spec/plan git-rm'd per the lifecycle convention. refs #169
