MVP signal
This is an implementation-readiness signal, not proof that the full definition of done is complete.
Definition of done scorecard
This page is an honest implementation audit against the 12 dimensions in the definition of done. It is not a declaration that Aristotle is finished.
Gate status
This is an implementation-readiness signal, not proof that the full definition of done is complete.
Production requires no dimension below 3 and critical dimensions at 4 or above.
Dimensions
Evidence: Learner profiles capture stage, subject, pathway, age band, confidence, goal, style, pace, practice pattern, support notes and accessibility preferences.
Gap: Needs richer age-specific copy, dynamic reading-level adjustment and usability testing with learners across access needs.
Evidence: Profiles track concepts, mastery states, evidence counts, scores, confidence, misconceptions, review timing, difficulty, emotion signals, reflections, frustration and confidence calibration.
Gap: Needs stronger psychometric validation and multi-session calibration.
Evidence: EYFS to A-Level coverage includes starter concepts, prerequisites, problems, mastery signals, remediation, extension paths, validation markers, structural audit coverage and a live curriculum review queue.
Gap: Needs completed expert-reviewed depth for each subject, exam board and nation-specific variant before production trust.
Evidence: Subject diagnostics update concept-level evidence and progress states using rotating recall, explanation and application rubric dimensions.
Gap: Needs larger item banks, adaptive branching and externally validated rubrics.
Evidence: Lessons adapt by stage, concept metadata, prior evidence, hints and remediation outcomes.
Gap: Needs stronger generation control, content review and multiple lesson formats per concept.
Evidence: Checks classify unsupported, misconception, partial and correct evidence with scores, confidence, scaffolding and explicit evidence dimensions: recall, procedural fluency, explanation, application, transfer, error correction, teach-back and confidence calibration.
Gap: Needs subject-specific rubric validation, calibrated item difficulty and delayed retention evidence across real learners.
Evidence: Misconceptions trigger targeted next actions; concepts expose remediation strategies.
Gap: Needs more nuanced misconception taxonomies per subject and worked-example remediation.
Evidence: Dashboards, learner model, educator view, aggregate analytics and records page expose progress, scores, learning gain, misconception hotspots and evidence.
Gap: Needs charts, cohort trends and longitudinal reporting.
Evidence: Accounts persist learner profiles; share codes allow controlled adult access.
Gap: Needs password reset, multi-learner account management polish and production session policies.
Evidence: High-risk learner inputs create safety audit events, stay open for review, require no mastery advancement; younger learner profiles can record guardian acknowledgement; curriculum concepts can be blocked or sent for revision by reviewers.
Gap: Needs external safeguarding review, operational ownership, moderation tooling and expert content accuracy review before production.
Evidence: Core flows are navigable in browser across desktop and mobile-sized viewport.
Gap: Needs usability testing with real learners across age ranges and assistive needs.
Evidence: Django tests cover coverage, learning flows, safety, account persistence, privacy, adult access and operations; CI runs checks, migration drift detection and tests; server exceptions are captured into an operational event trail; backup, smoke and learning-load commands can record operational evidence.
Gap: Needs deployment config, external monitoring, alerting, production database setup and high-volume load testing.
