The site credited 2016 to Bộ GD&ĐT, which those files were never fetched
from. Both datasets come from published articles: 2016 from an aggregator
on dtnt.bacninh.edu.vn listing one spreadsheet per exam cluster, 2017 from
baotintuc.vn. The README, the architecture table and the web footer all
repeated the ministry claim.
The footer now shows each dataset's full article URL as a link rather than
a bare host, so the citation can be checked. That needs overflow-wrap on
the footer: the 2016 URL is 110 characters with no break opportunity and
would otherwise scroll the page sideways on a phone.
Also records that a full 2016 crawl has been run successfully. The host was
marked unconfirmed and data/2016/ described as the only recoverable copy;
both datasets are now rebuildable from source.
The pipeline is now Go outside web/. differential-parity.mjs becomes
assembler/internal/verify, reachable as `assemble verify A B`. The port fixed a
real weakness: the JavaScript hashed each row's fields joined bare, so a value
shifted across a column boundary produced the same digest. A test now pins that.
The hub still rendered "Phiên bản cũ của trang 2017" above a permanently empty
list — it split datasets on id.includes("old"), and both such datasets are gone.
The heading and the filter are removed. index.html titled every page "THPT QG
2017", including 2016 and the hub, because one file is copied to every route;
the static title is now neutral and the app sets the dataset's own.
Dead code removed: the isOld2/containsOld branches in the stats block, which
only 2017-old2 could ever reach; SUBJECT_LABELS, DATASET_IDS and the unread
`short` subject field; an unused vite.svg and a favicon link to a file that
never existed; two unused CSS rules and --shadow-sm; site.Paths.Root.
Corrected comments that were confidently wrong rather than merely stale: the
reader claimed to be row-streaming when both implementations decode the whole
workbook into memory first, and the fidelity oracle still spoke of 299 input
files when it covers 182. Candidate counts in the hub now derive from
datasets.json instead of being written a second time as prose.
plans/ is emptied. The parity report it held was cited by docs/data-pipeline.md,
so the evidence that the recovered foreign-language scores are real — not the
citation, the four arguments themselves — is now inline there.
Verified: 2017 rebuilt after the writer change hashes identically to the build
before it.
The repository now reads as the pipeline it is: crawler fetches, parser
converts, assembler verifies and publishes, with data/ and web/ as the stores
they hand work through. go-parser is renamed parser now that there is no other.
The assembler replaces build-db.js and assemble-site.js. It compiles the
parser, builds and verifies each database, compresses it, runs the Vite build
and assembles _site — one command, and the only place that knows the order.
It also closes a real hole: nothing previously asserted that a database reached
the site. An empty staging directory assembled happily, so every page rendered,
every query 404d and CI stayed green. The row-count and size guards could not
catch that, since they only run when a database was built at all.
Removing Node from the root forced the dataset list out of web/src/datasets.js,
which the assembler cannot import. datasets.json is now the registry both sides
read — JSON because Go and the browser both parse it without a dependency —
while presentation stays in the web app, keyed by id and cross-checked against
the registry so a half-added dataset fails instead of half-working.
Guards verified by making each one fail: a missing database, and an expected
row count one higher than the truth.
Move the frontend into web/, the repo's only npm workspace, and replace the
JS crawler with a Go module covering both remaining datasets. The crawler
writes to a .part file and renames on completion: writing straight to the
destination left truncated files that the skip-if-present check would then
skip forever.
Remove the 2017-old and 2017-old2 datasets. They were successive publications
of the same exam, kept side by side so the disagreement stayed inspectable;
the current 2017 supersedes them and they remain in git history.
Recover the 2016 crawler source from the Internet Archive's copy of the
aggregator article, whose original host no longer resolves. All 119 filenames
are verified against data/2016 in both directions, but no archive captured the
spreadsheets themselves, so the host still serving them is unconfirmed and
data/2016 remains the only confirmed copy.
Filenames are load-bearing throughout: go-parser sorts inputs bytewise and
inserts last-wins, so they decide which row survives a duplicate exam number.
