- admission-blocks.js: expand from 8 core blocks to all 49 official 2017
blocks (A00-A11, B00-B08, C00-C20, D01-D15) the DB schema can support.
Detail card now shows every qualifying block, sorted best-first
- custom-query: rewrite "Top 100 Long An" preset using UNION ALL +
ROW_NUMBER() OVER PARTITION BY so we can label each row with the
winning block code, not just the score
Computes each student's max admission-block sum across 49 official 2017
blocks (A00-A11, B00-B08, C00-C20, D01-D15, restricted to subjects
present in our DB — no Đức/Nhật languages). One row per student, sorted
by their personal best, top 100.
SQL note: SQLite's MAX(x,y,...) scalar returns NULL if ANY arg is NULL.
Each block expression is wrapped in COALESCE(..., -1); NULLIF(..., -1)
restores NULL only for students with zero computable blocks.
Old palette reused gold for both "Trung bình" and "Xuất sắc" — confusing.
Replaces with League of Legends / TFT rarity ladder where each rank gets
a distinct hue that also communicates relative rarity.
Tiers:
≤ 1 Điểm liệt (common) white / gray
< 5 Chưa đạt (uncommon) green
5-6.5 Trung bình (rare) blue
6.5-8 Khá (epic) purple
8-9 Giỏi (legendary) gold
9-10 Xuất sắc (prismatic) multi-color gradient
- admission-blocks.js: scoreTier now returns 6 keys (common..prismatic)
plus the "điểm liệt" tier (≤1) that didn't exist before
- student-detail.jsx: TIER_LEGEND updated to 6 entries with ranges
- App.css: --tier-{common,uncommon,rare,epic,legendary,prismatic}-*
tokens, light + dark variants each AA-contrast verified; applied to
.score-cell, .score-tile, .tier-legend-item
- App.jsx owns query state, syncs to URL via ?q= (works for SBD or name);
hydrates initial search from URL on DB ready
- Loading panel now shows DB size (~47 MB) and one-time download note
- Footer reports total student count from the live DB
- Keyboard shortcut '/' focuses the search input when not already typing
- StudentDetail: "Chia sẻ" button uses Web Share API or clipboard with a
formatted multi-line summary including a deep-link URL
- StudentDetail: inline tier legend (▽ ○ ◆ ★ ✦) with score ranges
- ScoreTable cells now use background tint matching detail tiles
- CustomQuery: presets grouped into 4 categories; auto-runs PRAGMA
table_info(student) on first DB ready so the tab opens with the schema
visible instead of a blank textarea
- SearchForm accepts controlled value prop for URL hydration
- Add Be Vietnam Pro web font for consistent Vietnamese diacritic rendering
- custom-query: two new presets filtered by Long An (SBD prefix 49):
Top 10 điểm Toán, Top 100 khối A (Toán+Lý+Hóa)
- search-form: show clickable example pills ("49008235" /
"Nguyễn Minh Tiến") next to the empty-state hint; clicking fills
the input and triggers the debounced live search
- App.css: .example-btn pill styling matching preset buttons
Restore the 54 corrected-export files that previously lived in
data/raw/update/ (removed in 37cf9df). Kept alongside data-old/ for
historical reference; not consumed by build pipeline.
Dataset update:
- Crawl all 63 .xls province files from baotintuc.vn CDN (original source)
- Old xlsx dataset moved to data-old/ for reference
- Net: +13,719 students (Hà Nội +7,275, HCM +6,445) — the old .xls → xlsx
conversion silently dropped rows beyond the 65,536 per-sheet cap
- Also removes 1 bogus header row that had leaked into the old DB
- 100% identical scores on the 847,348 SBDs present in both datasets
Build pipeline:
- build-database.js: iterate ALL sheets per workbook (fixes the overflow
loss) and accept .xls in addition to .xlsx
Audit tooling:
- scripts/crawl-baotintuc.js: idempotent 63-province downloader
- scripts/diff-datasets.js: compares two DBs by SBD set and per-column
score deltas
- Move 63 Excel files from data/raw/ to data/ (single flat dir)
- Remove all 53 files in data/raw/update/: verified identical SBD
coverage to raw/ (847349 rows either way), so they added no new
students — only potential score corrections that can be reintroduced
later if source is recovered
- Update build-database.js to read data/ directly
- Add scripts/audit-row-counts.js: compares source row count to DB row
count to verify zero-loss parsing
- Point check-duplicates.js at new data/ location
- Drop 10_LamDong_GNFT (1) and 2.BacKan_YQNX(1): identical row content to
siblings (Excel metadata differs but file size & sheet rows match)
- Add scripts/check-duplicates.js to detect byte-identical and row-identical
files across data/raw and data/raw/update
Add ho_ten_ascii column with normalized names (no diacritics, lowercase)
so users can search "nguyen van a" to find "NGUYỄN VĂN A".
- ASCII input searches against ho_ten_ascii column
- Vietnamese input searches both ho_ten and ho_ten_ascii
- Indexed for fast lookups
- Remove Gradle build, Java sources, Hibernate config, old database.sqlite
- Move Excel data files from src/main/resources/raw/ to data/raw/
- Move Vite+React app from web/ to project root
- Merge package.json into single root-level config
- Update build script paths and CI workflow accordingly
- Node script parses 119 Excel files into SQLite (847K students)
- Vite + React frontend with sql.js for client-side querying
- Search by exam ID (số báo danh) or student name
- Gzipped DB (36MB) with download progress bar
- GitHub Actions workflow for GitHub Pages deployment
