Fixes the bug where a specialization could show "Achievable" while no per-set ceiling cell surfaces a path to it. Reproduction: pin SP2=Business of Health & Medical Care, SP4=Foundations of Fintech, SP5=Corporate Finance, SE1=GIE; rank HCR first. Healthcare showed Achievable but every ceiling cell excluded HCR. Root cause: computeCeiling used strict > on count alone, so the first equal-count combination found won permanently and HCR-including outcomes were never recorded. Changes: - Replace per-(set, choice) computeCeiling loop with a single full-tree searchDecisionTree DFS. Both the per-set ceiling table and a new ranked top-K plan list (default K=10) are populated from one enumeration. - Comparison rule everywhere is (count desc, priority score desc, deterministic-tiebreak). priorityScore extracted from optimizer.ts into a shared priority.ts module used by both call sites. - Heuristic enumeration ordering: select the first reachable ranked spec as priorityTarget; reorder DFS children at every level so target- qualifying courses are tried first. High-priority outcomes surface in early iterations instead of being blocked by less-relevant equal-count results. - Bounded search: terminate on saturation (top-K stable for 500 iterations) or hard cap (10000 iterations); set partial=true if cap hit. Mitigates the worst-case enumeration cost. - Worker protocol: tagged-union response with topKUpdate, choiceUpdate (per-cell, replaces per-set setComplete), and allComplete events. - App state adds topPlans/topPlansPartial slices and an adoptPlan action that pins a plan's full course assignment in one click. Also fixes loadState's stale "ranking.length !== 14" check (now uses SPECIALIZATIONS.length so HCR-era saved state restores correctly). - New TopPlans component renders the ranked list with adopt buttons, placed above CourseSelection in the right column. - 17 new tests in searchDecisionTree.test.ts covering priority scoring, bounded ranked list, comparison rule, target selection, the user's reproduction scenario, streaming monotonicity, saturation termination, and a performance smoke test (< 5s for the 8-open-set case). - Existing decisionTree.test.ts: one test amended for per-cell streaming semantics; remaining 3 unchanged and passing.
React + TypeScript + Vite
This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
Currently, two official plugins are available:
- @vitejs/plugin-react uses Babel (or oxc when used in rolldown-vite) for Fast Refresh
- @vitejs/plugin-react-swc uses SWC for Fast Refresh
React Compiler
The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see this documentation.
Expanding the ESLint configuration
If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
export default defineConfig([
globalIgnores(['dist']),
{
files: ['**/*.{ts,tsx}'],
extends: [
// Other configs...
// Remove tseslint.configs.recommended and replace with this
tseslint.configs.recommendedTypeChecked,
// Alternatively, use this for stricter rules
tseslint.configs.strictTypeChecked,
// Optionally, add this for stylistic rules
tseslint.configs.stylisticTypeChecked,
// Other configs...
],
languageOptions: {
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
// other options...
},
},
])
You can also install eslint-plugin-react-x and eslint-plugin-react-dom for React-specific lint rules:
// eslint.config.js
import reactX from 'eslint-plugin-react-x'
import reactDom from 'eslint-plugin-react-dom'
export default defineConfig([
globalIgnores(['dist']),
{
files: ['**/*.{ts,tsx}'],
extends: [
// Other configs...
// Enable lint rules for React
reactX.configs['recommended-typescript'],
// Enable lint rules for React DOM
reactDom.configs.recommended,
],
languageOptions: {
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
// other options...
},
},
])
