giles	79fa28e55d	commerce: promo rules (percent/fixed/bundle/member) as relations (17 tests) ... promo.sx — four promo types as tagged tuples; per-promo discount is pure integer arithmetic, but enumeration is relational: promo-discounto and promo-applieso run forward ("which codes apply, for how much?") and backward ("which code yields this discount?"). project grounds the membero-bound promo. applicable-promos / promo-amount-for deterministic helpers.

giles	a0f3a1177e	commerce: public session API + per-line audit + checkout stub (12 tests) — Phase 1 done ... api.sx — session facade {:ctx :cart}: commerce-add/remove/set-qty/total/ count/lines, commerce-can-add? catalog validation, commerce-explain per-line audit breakdown, commerce-checkout Phase-3 stub. Completes Phase 1 (catalog + cart + deterministic totals). Total 66/66 across 4 suites. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-06 23:46:51 +00:00
giles	29955831be	commerce: deterministic subtotal + jurisdiction-relational tax (20 tests) ... price.sx — cart-subtotal (unit price = base + variant delta, default 0), taxo facts indexed by (jurisdiction, product-class, customer-class) -> bps queried both directions, apply-bps half-up integer rounding, cart-total returning {:subtotal :discounts :tax :total} reproducible from (context, cart).

giles	35957d779f	commerce: cart line items + add/remove/set-qty + relational view (18 tests) ... cart.sx — cart as an ordered list of (sku variant qty) lines. Pure operations: cart-add (merge-or-append), cart-set-qty (0 removes), cart-remove, with cart-qty/count/skus/empty? accessors. cart-lineo exposes lines relationally via membero. Total 34/34.

giles	25f3734eab	commerce: catalog facts + multidirectional relations + conformance harness (16 tests) ... catalog.sx — catalog snapshot (products/variants/stock as fact tuples), relational accessors (producto/varianto/stocko, derived priceo/classo/ unit-priceo) usable forward and backward, deterministic catalog-price/ -class/-has? helpers. Money is integer minor units. conformance.sh runs suites on the miniKanren stack and emits scoreboard.{json,md}.

giles	1902cce57f	plans: rename store-on-sx → persist-on-sx; clarify it's persistence not shop, and scope (log+kv facets, blobs delegated, cache excluded) ... Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-06 18:20:14 +00:00
giles	ff537bfba2	plans: six subsystem outline plans for the SX rewrite (store, commerce, identity, content, events, host) ... Gap analysis from the five-subsystem set (acl/feed/flow/mod/search): - store-on-sx: event-sourcing foundation the others fake with in-memory lists (build first) - commerce-on-sx: catalog/cart/pricing/orders on miniKanren (+ store + flow) - identity-on-sx: OAuth2/sessions/membership on Erlang (the core acl assumes) - content-on-sx: documents/blocks/CRDT on Smalltalk - events-on-sx: calendar/ticketing on Datalog + flow-driven delivery - host-on-sx: the web boundary — off Quart onto native server+SXTP now, dream-on-sx next All DRAFT outlines; substrate choices proposed, not final.
