Architect drift review over a4cfe5c..HEAD (covers the previously-unaudited
EMA node and MACD PoC plus the #40 composite multi-output cycle): status
clean. C8/C7/C4 preserved (one port, one row per eval, K co-fresh base
columns — structurally identical to OHLCV); C23 honoured (ItemLowering::
Composite.output is Vec<(usize,usize)>, no name in the compilat; the
compiled-view render stayed bit-identical). EMA and MACD PoC carry no
ledger drift.
Resolution of the three minors:
- Ledger lagged the new behaviour: added a "Realization (cycle 0018)" note
under C9 recording that a composite's output is now a named K-field record
(Vec<OutField>), the same arity C8 already grants a leaf, names dropped at
lowering (C23). Amended here (ledger amendment is the audit's job).
- blueprint.rs module-doc / Composite struct-doc / new-doc still said "one
output port" singular — updated to "output record".
- Non-workspace fieldtest From<Sma> debt is pre-existing (cycle-0016) and
already tracked as #42; not re-filed.
No regression scripts configured (profile regression: []), so the architect
review is the sole gate. Carry-on: the next natural iteration is the #41
legibility sibling (input-role + param naming at the composite boundary).
