- puga/network.py + tools/network.py: model a multi-base chain (e.g. mine LST at one base,
ship it, consume it at another). Simulates each base independently, nets a transferred
material's producer-surplus against consumer-need, charges real freight only on what's
moved, cm_free for a founding covered by a Core Module Kit. Worked example in plans/chains/.
- puga/saturation.py: real price-band filtering. FIO's order_book NarrowPriceBandLow/High and
WidePriceBandLow/High match APEX's own displayed Price Band exactly (verified live) - an
order outside it is a stale artifact, not just uncompetitive. Added in_band() and
effective_demand(); effective_supply() gained the same hard band filter alongside its
existing soft vwap-proximity filter (renamed that param mult to free up `band`). Wired into
tools/scan.py stage 2 in place of the raw, unfiltered demand figure. Was flagged as an
unimplemented refinement in saturation-design.md since the original design review.
- tools/sell.py: self-contained tranche split (aggressive tranche capped at a volume quantile,
median normally or 80th pct with --tight when a payment is imminent and stockout risk
outweighs margin; patient tranche priced under the next competitor tier). Instant-bid
comparison moved behind --show-bid (off by default).
- Docs and roadmap updated accordingly.
