The cycle-0092 restructure of stage1_r_graph into stage1_signal() +
wrap_stage1r() (#165) nests the signal as a Composite, which prefixes its
param-space names (stage1_signal.fast.length). The sweep / walkforward / MC
by-name binding (.axis("fast.length")) is reconciled by suffix-resolution:
FAST_LENGTH_SUFFIX / SLOW_LENGTH_SUFFIX consts + per-axis
.ends_with(...).expect(...) lookups + stage1_r_friendly_name arms mapping the
prefixed names back to the bare manifest names (the #137 stop-knob pattern,
extended) — all in crates/aura-cli/src/main.rs.

Claim (verified by the cycle-0092 architect review + the green suite): this is
hand-kept in lockstep and grows per nesting-level / per knob; a miss panics the
sweep path (the .expect). Build-validated today — full suite green, no
correctness risk in the interim — but a maintenance hazard.

Single-source the prefix-resolution: one helper / const set that the SMA-axis
resolution and the friendly-name remapping both derive from, so a new knob or an
added nesting level cannot silently desync (or panic). Surfaced by the
cycle-0092 architect drift review (classified debt-med).
