Cycle 3 of the verb-dissolution milestone (96dc783..a047af6). Architect drift
review over the range returned clean.
What holds:
- Pure sugar confirmed: `git diff 3a03617..a047af6 -- crates/aura-campaign
crates/aura-engine crates/aura-research` is EMPTY. All walkforward-specific
logic is confined to aura-cli. Invariant 10 (no verb-special engine logic) and
invariant 12 (one campaign path, via run_campaign_returning) preserved.
- No new campaign vocabulary: reuses StageBlock::WalkForward / WfMode::Rolling /
RiskRegime::Vol — the #160 3-copy vocab guard needs no update. C18:
content-addressed process + campaign + run recorded, e2e-verified.
- C10/C20: the stop binds as a single RiskRegime::Vol (structural, not a swept
param axis), consistent with the prior risk-regime cycle; Fork A refuses a
multi-value stop rather than silently re-semanticizing it.
- The two documented inline deviations are sound: full_window == wf_full_span on
the Real arm (both delegate to probe_window); raw_matches_wrapped correctly
matches wrapped fast/slow and the unwrapped stop.
Deferred debt (all [low], tracked, carry-on):
- Fork A narrows the surface: the inline path swept the stop as an IS-refit grid
axis (RGrid.stop_* are Vec); the dissolved path refuses a multi-value stop. The
byte-anchor covers the single-stop grade — "byte-for-byte" is scoped, not total.
Design-ratified on #210 (Fork A / the risk-regime model: the stop defines R and
is compared, never argmax-swept).
- The reducer's .expect()/unreachable! on report shape mirrors the inline
reducer's posture; anchor-guarded for today.
- The #214 arg-bundle is now at its third instance (rule-of-three trip point);
deferral to after the mc dissolution is deliberate (noted on #214).
Full workspace suite green; clippy --all-targets -D warnings clean; the
equivalence anchor walkforward_real_e2e_pins_the_exact_current_grade green through
the dissolution. Spec + plan removed (git rm) per the cycle lifecycle.
