Architect review over dd23ea3..HEAD (the #234/#152 cycle, 6 commits).
What holds (architect-confirmed): CostSpec is a closed, deny-unknown-
fields vocabulary with typed slots mirroring RiskRegime, field names
conforming to the builders' ParamSpec names; cost-less docs hash
byte-identically (C18); cost threads through the single MemberRunner
seam so every campaign stage nets uniformly; costed families reproduce
bit-identically incl. Carry; the #221-deleted leg is rebuilt optional
(net = gross under the empty model); both cost_graph leaks replaced by
the interned single source (#152).
Resolved this close: [high] the C10 realization notes contradicted
shipped reality — the two 'wired on the run path via --cost-*' claims
carry superseded-annotations, the 0084 carried-debt note a discharged-
annotation, and a new cycle-net-r realization documents the campaign
cost block, the net-by-default decision, the manifest/reproduce
round-trip, and the returned net_r_equity tap; [medium] two dangling
persist_traces_r docstring references reworded to what exists;
[medium] the one-knob-per-cost-node invariant behind the manifest
round-trip is now unit-pinned (exactly one distinctly-named knob per
shipped builder).
Cycle spec and plan (git-ignored working files) discarded per
convention.
