GREEN for 78e68e6's RED. aura_runner::reproduce::load_family resolved
only the derived C18 handle '{family}-{run}' while the registry's
enumeration exposes the bare name factor — the natural
list-then-reproduce library workflow dead-ended (found by the #295
fieldtest; predates the extraction byte-identically). Resolution now:
exact-handle match keeps first precedence; a bare name naming exactly
one stored run resolves as fallback; an ambiguous name (several runs,
or a name/handle collision) refuses without guessing, listing the
candidate handles. Two additional tests pin the ambiguity refusal and
the handle-precedence-on-collision semantics.
Ledger record-reality rider: the C18 #158 paragraph claimed reproduce
refuses an unknown id with exit 2; the code has always exited 1 —
correct per C14's partition (the id names missing recorded state, a
runtime failure, not a usage error). The paragraph now records the
actual behaviour and the new name-fallback semantics.
Verification: cargo test --workspace green (1477 passed, 0 failed);
clippy --workspace --all-targets -D warnings clean.

Registry::load_family_members() exposes the bare name factor while
aura_runner::reproduce::load_family exact-matches only the derived C18
handle '{family}-{run}' — the natural list-then-reproduce workflow
dead-ends on its first attempt (found by the #295 fieldtest; predates
the extraction byte-identically). The test pins: the enumerated
identity of an unambiguous single-run family resolves through
load_family to the same family the canonical handle names.

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).
