Stacked on #564. This PR sits on top of #564 (isValidCest, formatCest, parseCest, getCest) and merges after it, which in turn sits on #566, #569, #565, #567, #573, #561, #563, #562, #560, #559, #558 and #588. Its base branch is claude/cest, so the diff shown here is the CID-10 change alone. Part of stack #591, with #576 on top of it.

What

A CID-10 lookup (Classificação Estatística Internacional de Doenças e Problemas Relacionados à Saúde, 10th revision, the Brazilian Portuguese edition DATASUS publishes), modelled on the CBO and CNAE lookups: a generated table under src/_internals/constants/, a generator under scripts/ wired into scripts/data.ts (and so into the scheduled Update datasets workflow), and four utils.

API

type Cid10 = { code: string; description: string };

getCid10(value: string): Cid10 | null;
isValidCid10(value: string): boolean;
formatCid10(value: string): string;
parseCid10(value: string): string;
getCid10('A00.0'); // { code: 'A000', description: 'Cólera devida a Vibrio cholerae 01, biótipo cholerae' }
getCid10('a000'); // same record
getCid10('A00'); // { code: 'A00', description: 'Cólera' }
getCid10('A00.5'); // null
getCid10('A00-0'); // null (not a documented form)

isValidCid10('I10'); // true (a category that is not subdivided)
isValidCid10('I10.0'); // false

formatCid10('f322'); // 'F32.2'
formatCid10('A00'); // 'A00'
parseCid10('A00.0'); // 'A000'
  • Both levels are found: the 3 character categories and the 4 character subcategories, with the dot (A00.0) or without it (A000). Letter case and surrounding whitespace are ignored; anything else (another separator, a fifth character, a dagger or asterisk suffix, a non-string) gives null / false. Nothing throws, and the lookups use own-property checks.
  • code comes back upper case and without the dot, the form the DATASUS tables store; formatCid10 prints it.
  • formatCid10 / parseCid10 are structural, like formatCnae / parseCnae: progressive mask 000.0, capped at 4 characters, "" for a non-string.
  • The shared form check lives in src/_internals/normalize-cid10, so getCid10 and isValidCid10 do not duplicate it.

Bundle size (please apply tree-shaking: accepted)

From npm run build && npm run check:tree-shaking:

Export Minified Gzipped
getCid10 1 055 096 B (1030.4 KB) 150 386 B (146.9 KB)
isValidCid10 27 697 B (27.0 KB) 7 575 B (7.4 KB)
formatCid10 1 313 B 803 B
parseCid10 1 031 B 637 B

getCid10 is now the heaviest export of the package by a wide margin: 2045 categories and 12188 subcategories, about 850 KB of description text alone. It is paid only by whoever imports getCid10; no pre-existing export changed size (isValidCpf is still 1 354 B). The full-import bundle goes to 1 745 296 B (gzip 327 410 B), and the published dist grows by about 2 MB (one ESM and one CJS chunk of the descriptions).

To keep validation cheap, isValidCid10 does not call getCid10. The generator writes a second table with the same codes and no descriptions (A00: "019" = A00.0, A00.1, A00.9; I10: ""), so checking a code costs 27 KB instead of 1 MB. A test asserts both tables hold exactly the same codes. The two tables are separate modules (constants/cid10.ts for the codes, constants/cid10-descriptions.ts for the descriptions), so nothing that reads one loads the other, which matters for Node, Deno and native browser imports, where nothing tree-shakes. The generated modules hold the tables and nothing else: the form regex sits next to normalize-cid10, its only reader, and the length in src/parse-cid10/constants.ts the way parseCnae keeps its own. Without that split, dist/get-cid10.js reached constants/cid10.ts for the regex and dragged the 26 KB code table with it. Measured over each subpath and everything it imports: dist/get-cid10.js 985 216 B (was 1 011 781 B), dist/is-valid-cid10.js 27 081 B, dist/format-cid10.js 750 B, dist/parse-cid10.js 318 B. Both getting-started bundle-size tables and the getCid10 docs point to the lazy subpath import.

Sources

  • http://www2.datasus.gov.br/cid10/V2008/descrcsv.htm : the DATASUS page that documents the CSV files. It proves the file names, the ; separator, the ISO-8859-1 encoding, the columns (CAT / SUBCAT, DESCRICAO, CLASSIF for dagger/asterisk), that SUBCAT is written "sem incluir ponto", and that CID-10-SUBCATEGORIAS.CSV also lists the categories that have no subcategory. It links the archive below.
  • http://www2.datasus.gov.br/cid10/V2008/downloads/CID10CSV.zip : the archive itself (CID-10-CATEGORIAS.CSV, CID-10-SUBCATEGORIAS.CSV), SHA-256 84f23809275575f751255048064bbb244b0de33fd5987ab98df0f98e5f5d2c95, files dated October 2007. Every expected value in the tests was read from these two files. The 263 categories with no subcategory appear in both files with identical descriptions; no orphan subcategory, no duplicate code.

No third-party implementation or mirror was used.

Verification

  • npm run check: pass
  • npm run test -- --run: 189 files, 6245 passed
  • npm run test:coverage: 100% statements, branches, functions, lines
  • npm run build: pass (attw and publint clean)
  • npm run check:api: pass; the regenerated report (+18 lines, additions only) is folded into the feature commit, and build(api): check the public API against the last npm release instead of a committed report #576, at the top of the stack, deletes the file for good
  • npm run check:unused: clean
  • npm run check:duplication: 0 clones
  • npm run check:tree-shaking: pass, numbers above
  • npm run check:commits: 0 problems
  • npm run test:mutation on the five new source files: 29 mutants, 29 killed, 100%; re-run on the two files this branch changed afterwards (normalize-cid10, parse-cid10): 23 mutants, 23 killed, 100%
  • npm run test:bun: 6245 pass, 0 fail. npm run test:deno: 6245 passed, 0 failed (a first Deno run caught a wrong property of mine, case insensitivity asserted over arbitrary Unicode, where "ẖ".toUpperCase() yields an ASCII H; it now uses asciiAlphanumericText like parsePassport and parseIban)
  • node scripts/cid10.ts run end to end against DATASUS after the download was rewritten; the regenerated cid10-descriptions.ts is byte-identical to the committed one. It was run end to end three times before that; the committed tables are its output after vp lint --fix and vp fmt, and two consecutive runs gave byte-identical files
  • npm run build:llms and npm run build:site run; browser tests and the full Stryker run were not run

After the rebase onto the stack

main has since rewritten both docs/utilities.md files into the per-utility format (a ### heading, a one-line description, bullets, an example and one shared Source: line per family), deleted the tracked docs/llms.txt and docs/llms-full.txt and added jsr.json. The ## CID-10 section was rewritten into that format in both languages, the two generated files were dropped, and the four new subpaths were added to jsr.json (npm run build:jsr reproduces it). Re-run on the rebased branch: npm run check, npm run test:coverage (100%), npm run build, npm run check:api, npm run check:unused, npm run check:duplication (0 clones), npm run check:commits, npm run check:tree-shaking, npm run build:docs and bun test src (7457 pass): all pass.

Open points

  • A maintainer has to dismiss one CodeQL alert before this can merge. www2.datasus.gov.br does not answer on port 443 (datasus.saude.gov.br and tabnet.datasus.gov.br both 404 on the archive, and the CSVs are not published outside the zip), so the generator downloads over plain HTTP and checks every byte against the SHA-256 above. CodeQL cannot see that check, so it reports js/insecure-download ("Download of sensitive file from HTTP source") and the required CodeQL check fails. There is no in-code way to resolve it: an oxlint-disable comment silences a different engine, code scanning here is GitHub's default setup, and CodeQL does not honour in-source suppression comments. The only options are dismissing the alert ("Won't fix", pointing at CID10_ZIP_SHA256) or dropping the dataset, so the alert needs one dismissal from a maintainer.
    What this branch did fix is where the alert points. It used to be filed against src/_internals/fetch-with-retry/fetch-with-retry.ts:94, because the URL flowed through fetchSortedRecord into the library's fetch helper, so dismissing it would have covered every future insecure download reaching that same line. The generator now does its own fetch, with its own retries, and sorting moved to scripts/sort-record.ts so nothing is duplicated; the alert is now source and sink inside scripts/cid10.ts, which is the file a maintainer would be reviewing when dismissing it.
    State on 95010e14: the failing CodeQL check reports exactly one alert, #44 js/insecure-download at scripts/cid10.ts:82; the earlier validate cpf numbers with letters fix #39 #42 (fetch-with-retry.ts) and Fix test description #43 (previous line in scripts/cid10.ts) show as fixed. The other two open alerts on the merge ref, Improve tests #3 and Add CPF generator #4 zizmor/dependabot-cooldown on .github/dependabot.yml, are not from this branch: they exist on main too and fix: resolve the open Dependabot and code scanning alerts #557 fixes them. Merging fix: resolve the open Dependabot and code scanning alerts #557 will not turn this check green; dismissing PIS validation #44 will.
  • A DATASUS change freezes the other datasets. scripts/data.ts runs every generator in one job and exits non-zero if any of them fails, before the workflow opens its pull request. So on the day DATASUS publishes a revised archive, the digest check fails the weekly run and banks, cbo, cfop, cities, cnae, legal-natures, ncm and states get no refresh either, every week, until someone bumps CID10_ZIP_SHA256. The archive has not changed since 2014 (Last-Modified: Mon, 13 Oct 2014), and a wrong table is worse than a late one, so the check stays; CONTRIBUTING.md and the constant's comment now spell out the runbook. Making one generator's failure not hold the others back is a change to a shared script and belongs in its own pull request.
  • Flaky host. The DATASUS server timed out on several of my requests before answering. The generator retries the download twice with a linear backoff, but since scripts/data.ts fails the whole run when one generator fails, a bad DATASUS day still blocks that week's refresh of the other datasets. The host may also treat GitHub's runners differently from my machine; I could not test that.
  • V2008 only. The tables are the CID-10 V2008 archive, the one the DATASUS CID-10 site offers as CSV. Codes that are not in it, U07.1 (COVID-19) being the obvious one, are not found; the JSDoc and the docs say so. I did not search for another official machine-readable source of later additions, and none were added by hand.
  • eSocial. The task mentions eSocial S-2230. I did not verify the codCID layout against the eSocial documentation, so the code and docs make no claim about it.
  • scripts/data-summary.ts does not exist on main (it lives on the unmerged claude/standard-schema branch), so there was nothing to update. Whoever merges second adds the CID-10 entry there.
  • Signed-off-by. CONTRIBUTING asks for a DCO sign-off on every commit. Nothing in CI or commitlint enforces it, and while older commits on main carry it, none of the last 30 does. A sign-off is a personal attestation, so I did not add one in the maintainer's name; git rebase --signoff main adds it if wanted.
  • The heading "Classification codes (CBO, CNAE, NCM, CFOP, CST, CSOSN)" was left alone to keep its anchor; CID-10 got its own ## CID-10 section right after it, in both languages.

How this is measured

Every export is imported alone into an esbuild consumer bundle (minified, tree-shaken) built from the head and from the base of this pull request; the sizes are the resulting bundles, gzip is their gzipped size. 🔴 marks a regression: a pre-existing export that grew more than 20% and more than 256 B, or the bundle importing every pre-existing export growing more than 5%. 🟡 is growth under the threshold, 🟢 a decrease, ⚪ no change, 🆕 an export that does not exist on the base (never a regression), 🗑️ an export that was removed. An intentional increase is accepted with the tree-shaking: accepted label.

CID-10 is the code medical certificates and health systems carry, and there was
no way to check one or read its description. The four utils follow the CBO and
CNAE lookups: getCid10 returns the { code, description } record, isValidCid10
says whether a category (A00) or subcategory (A00.0, A000) exists, and
formatCid10 and parseCid10 convert between the printed and the stored form.

The table is generated by scripts/cid10.ts from CID-10-CATEGORIAS.CSV and
CID-10-SUBCATEGORIAS.CSV, the ISO-8859-1 files DATASUS publishes inside
CID10CSV.zip (CID-10 V2008): 2045 categories and 12188 subcategories. DATASUS
only serves that host over plain HTTP, so the generator checks the archive
against a reviewed SHA-256 and fails on any other content. The zip is read
with node:zlib, keeping the scripts free of new dependencies, and the
generator is wired into scripts/data.ts, so the Update datasets workflow runs
it.

The descriptions weigh about 1 MB minified (147 KB gzipped), paid only by
whoever imports getCid10. isValidCid10 reads a second, compact table of the
same codes (each category with the fourth characters of its subcategories),
so checking a code costs 27 KB instead; a test asserts both tables hold exactly
the same codes. The two tables are separate modules, so the is-valid-cid10
subpath does not load the descriptions in an unbundled runtime either. No
other export changes size.
CodeQL traced the plain HTTP URL of CID10CSV.zip through fetchSortedRecord into
fetch-with-retry and filed js/insecure-download against the library's own fetch
helper, which is misleading: the download only ever happens in the generator, and
dismissing an alert pinned to that line of fetch-with-retry would also cover any
future insecure download flowing through it. The generator now fetches and
retries the archive itself, so the URL and the alert stay inside scripts/, and
the sorting fetchSortedRecord did moves to scripts/sort-record.ts, shared by
both. CodeQL still reports the download, since the SHA-256 pin is not something
it can see; the alert has to be dismissed once, on scripts/cid10.ts.

CONTRIBUTING.md and the digest comment now say what to do when the check fires:
every generator runs in the same job, so a CID-10 mismatch leaves the other eight
datasets without a refresh pull request until a maintainer reviews the new
archive and bumps CID10_ZIP_SHA256.
CID10_FORMAT_REGEX and CID10_LENGTH lived in the generated module that also holds
the 26 KB validity table, so every consumer of the get-cid10 subpath pulled that
table into the bundle through normalize-cid10 without ever reading it. The regex
moves next to normalize-cid10, its only reader, and the length to
src/parse-cid10/constants.ts, the way parseCnae keeps its own LENGTH, which also
stops a utility from reaching into a dataset module for a constant.

dist/get-cid10.js and what it imports drop from 1011781 to 985216 bytes and
dist/is-valid-cid10.js now carries the table alone. The single-import figures
move by a few bytes, so the two bundle-size tables follow.
The generator only retried a fetch that threw, so a 503 from the DATASUS server,
which is as transient as the dropped connections it already covered, failed the
weekly run on the first answer. It now retries 429, 500, 502, 503 and 504 within
the same budget and still fails at once on a status the server means, such as
403, which downloadZip reports as before.

sortRecord assigned into an object literal, so an own __proto__ key in a dataset
would have set that object's prototype instead of becoming an entry. It rebuilds
the record with Object.fromEntries, which defines every key as an own property.
The CID-10 codes are filtered by a regex that cannot produce such a key, but the
helper now sorts every generator's dataset.
