Feature 10 of the co-design report: a personal, plural taste model.
- engine::taste:
- a choice is recorded only when the engine proves the two programs the
same circuit or the same state, by a proof (tableau, exact, state),
never by random inputs: it is about taste, never correctness;
- a Bradley-Terry logistic over differences of measured features (gates,
two-qubit gates, depth, two-qubit depth, T gates, modelled error) and
of the text (statements, kinds of gate, repetition, comments), ridge
penalised and fitted by Newton's method: deterministic everywhere;
- the rubric's parts (economy, clarity, insight, precision, utility),
each learned from its own choices; a ranking names where a part or the
cost puts another first;
- profiles personal and plural, by name, never pooled;
- typicality (one less engine::novelty's novelty) shown and never
learned; the novelty dial blends the standardised order by taste with
the order by novelty; a floor on each feature's spread keeps a feature
that barely varied from turning into certainty;
- measured: choices predicted as made and held out (last 100), the ones
nothing measured separates, and whether a ranking's first three are
built more alike than the cost's; scores about the candidates' mean;
- next: the least certain pair the engine proves equal; call for hosts.
- novelty::token is shared with it.
- The command line: taste choose | show | rank | next (files or --spec),
profiles in quantum-taste.json beside the user's key.
- MCP: taste_rank and taste_next read the person's profile; no tool
records a choice. initialize tells an agent so, and to call a program
new only when novelty_qasm says so.
- The Studio: "Your taste" in the Workbench (Compare two with the part a
choice was about, Rank by my taste with typicality and the dial,
profiles by name); an alternative that is the same circuit as the draft,
taken whole or refused whole, is a choice; Improve orders by the profile.
- Bindings: engine_taste in the page, taste in the desktop app.
- CI: wai-web's native engine tests count 11.
