Vision-assessment records the 2026-10-06 thinking round: propositions as
the unit, forecast semantics (mastery = P(correct unaided retrieval)), the
Beta-with-decay estimator (BKT rejected: binary-only, guess-less, never
forgets, unidentifiable at our volume; the weighted average completed with
prior + recency + uncertainty), the e-table over outcome x rung x missClass,
uniform 1/k credit (optional missed-field upgrade unruled), no new outcome
enum values, PRACTICE-ONLY perimeter (ruled — quiz nodes are session-scoped
plan objects, no honest mapping), mastery computed-on-read over the already
durable problem/conclude calls (no stored ledger, graph untouched).
Release-0.3 captures the owner's polish brain-dump (graph rendering toggle
separate from extraction + open home-view question, question keybinds/VIM,
session naming, markdown + graph exports, graph defaults, compaction dialog
Esc law, keyboard audit) and the schema-lock position with the persistent
surface inventory and pre-release gap list (schemaVersion stamps, pi-ai
pins).
