+`misc.httpmethod` is the eight methods RFC 9110 defines and PATCH; the register's
+other entries, WebDAV and DeltaV among them, do not ship. Its `safe` and
+`idempotent` are `true` or `false`, so a Go `bool` reads them, though `--format json`
+and `sql` write them as text, a table column carrying no datatype. `misc.protocol`
+carries a `number` and a `name`, the keyword itself where the register spells none out,
+and selects by either spelling.
+`misc.port` is the TCP assignments, rendering the number a port field holds with the
+IANA `service` beside it, and selecting by number alone. A draw spans the whole
+register, so pin `misc.port[443]` where a fixture needs a port a reader recognises;
+it stops at 49150, IANA assigning nothing above, so an ephemeral source port is
+`{int(49152,65535)}`.
+`misc.tld` is the root zone's delegated TLDs, keyed with the leading dot
+`misc.territory.tld` already carries, `.se`. Its `type` is the register's —
+`country-code`, `generic`, `generic-restricted`, `infrastructure` or `sponsored` — and
+its `unicode` the form the register displays, `.рф` for `.xn--p1ai` and the key itself
+for an ASCII one, which selects the row too, so `misc.tld[.рф]` renders `.xn--p1ai`. A
+draw spans the whole zone, `.arpa` and `.zuerich` alike, so pin `misc.tld[.com]` where
+a fixture needs one a reader recognises.
+`misc.loglevel` is the eight syslog severities, rendering the keyword a configuration
+writes, `err` and `info`, keyed by the numerical code a PRI encodes and selectable by
+either, so `misc.loglevel[3]` and `misc.loglevel[err]` are one row.
+`misc.loglevel.severity` is the name RFC 5424 spells, `Error` beside `err`; it
+selects nothing, the code and the keyword do.
 [`DATA-LICENSES.md`](DATA-LICENSES.md) names each table's source and licence.
 
+`misc.timezone` is every zone tzdb gives a shipped territory, from one apiece for most
+of them to dozens for the largest, weighted by the population GeoNames records in each,
+so `misc.territory[US].timezone` draws `America/New_York` far more often than
+`America/Nome`. It links to `misc.territory`, so `misc.territory[SE].timezone` is
+`Europe/Stockholm` and a drawn territory and zone agree. Its `offset` is the zone's
+*standard* offset, so do not pair it with a drawn `misc.datetime`: in a zone that
+observes DST it is the wrong one half the year, which is what storing a zone name
+avoids. A zone tzdb named recently — `Europe/Kyiv`, `America/Ciudad_Juarez` — is
+rejected outright by a consumer resolving it against older tzdata, so where the
+consumer validates the zone, pin one rather than draw it. There is no `UTC` row, tzdb
+giving that name no territory — spell it as the text `"UTC"`. `misc.useragent` carries
+`browser`, `device` and `os` beside the string, and `misc.car` a `make` and a `model`,

 ## Goals
 
-1. **Valid by construction** — every value passes the check its real consumer
+1. **The best fake-data tool available, and used because it is** — a developer
+   choosing a seed-data library or CLI, in any language, should find this the one
+   worth switching to, and every goal below it is what that costs. Merit is only
+   half the goal: once the grammar, the data and the CLI are complete and stable,
+   it ships where those developers install from and is announced where they read.
+2. **Understanding the code is part of the product** — it is a compiler with static
+   fences behind a small API, it will grow, and the people who extend it will not be
+   the people who wrote it. So reading cost is judged alongside behaviour: reaching
+   the unit behind a symptom without asking a person, changing one piece without
+   holding the rest, names that tell the truth, and a file that stands with no second
+   document open beside it. A simulated reader panel scores those four, the score is a
+   ratchet no release lowers, and [`AGENTS.md`](AGENTS.md) says what each pull request
+   owes it.
+3. **Valid by construction** — every value passes the check its real consumer
    applies; facts that belong together come from one draw, within a value and
    across categories.

    describe, with the same error every call, and `Template.Fake` cannot fail at all.

     parses and validates the whole set once upfront, so generating fixtures stays
     noise against a test's own runtime.

+12. **Data is sourced, or on its way there** — a shipped fact, a name, place,
+    code, id or classification, is read from a register or open dataset by a
+    [`data-import/`](data-import) script wherever one exists to read; where none
+    does yet a small hand-written set ships and [`todo.md`](todo.md) carries the
+    step that replaces it. Only non-factual copy stays authored. A sourced table
+    holds the rows its source holds: none is added by hand, and one is dropped
+    only by a rule the script states.
+13. **Breadth follows what most systems store** — a category is added in proportion
+    to how many real schemas hold it: names, addresses, phones, ids, money and
+    timestamps before anything domain-specific, and a catalogue serving one niche
+    waits behind everything serving many.
+14. **Realism is the default, inertness is selectable** — where a value could reach

+    the realistic breadth ships *and* so does the subset that provably reaches
+    nothing, each on its own path. A fixture that looks nothing like production

-- **`misc.country` carries a currency code, it does not link to `misc.currency`.**
+- **`misc` is what every locale shares.** A category whose facts differ by country
+  belongs in that country's locale, read from the register that country's own
+  records use; `misc` takes only sources that are international. NHTSA vPIC and
+  Mobility Sweden's registrations are national, so they build `en_US.car` and
+  `sv_SE.car`; `misc.car` waits for an international source rather than take one
+  of theirs.
+- **A register's canonical spelling loses to the one its domain writes.** Where a
+  source offers several spellings of one fact, the shipped one is what records in
+  that domain carry. `misc.timezone` reads `zone.tab` and not the `zone1970.tab`
+  that supersedes it, because the latter keeps one zone per set of countries that
+  have agreed since 1970: it spells Sweden `Europe/Berlin`, and no Swedish system
+  writes that. For the same reason `misc.language` takes the ISO 639-2 register's
+  first synonym over CLDR, which says "Chinese, Mandarin" for `zh`.
+- **`misc.territory` is the spine, and a `misc` table naming a territory links to
+  it.** Where every territory row has a child the column is a `parent`, and the
+  import drops the child rows whose territory the set does not ship — 17 of
+  `misc.timezone`'s, Antarctica's ten among them. Agreement across a record is
+  worth more than the last rows of a table. Where no such link can hold the fact
+  stays a column. Layer your own `misc.territory` over the shipped one and you
+  must layer `misc.timezone` too, or the link fails at load naming the row.
+- **A table whose register publishes no frequency draws evenly.** `misc.httpmethod`,
+  `misc.port`, `misc.httpstatus`, `misc.mimetype` and `misc.tld` weigh every row alike,
+  so GET is a ninth of the methods drawn. Goal 10 keeps an authored fact out of a
+  sourced table, and no register publishes how often a method, a port or a TLD is used,
+  so a weight here would be invented. Where one exists it is read, as `misc.timezone`
+  reads GeoNames populations and `sv_SE.first-name` SCB bearers.
+- **`misc.port` selects by number, and carries no `name`.** 29 of its services sit on
+  more than one port, `http-alt` on three, so `misc.port[http-alt]` could name no one
+  row. The number is what a port field holds anyway, and `misc.port[443].service`
+  reads the other way.
+- **`misc.car` is one flat table, not a make linked to its models.** A row is a make
+  and a model drawn together, so no render pairs a Volvo with a RAV4. Two linked
+  tables would reach the same pairs and add a selector nothing asks for; a make alone
+  is `misc.car.make`.
+- **`misc.territory` names its sovereign in a column, and there is no `misc.country`
+  table.** ISO 3166-1 codes territories, so `territory` is the honest name, and
+  `is_independent` in the register gives each one's state. A second table of the 195
+  sovereigns would hold a `DK` row beside the territory `DK` row, both carrying
+  Denmark's capital, currency, flag and TLD — two owners for one fact, drifting at
+  the next import. Splitting the columns to avoid that is worse: put `capital` on
+  the territory alone and a country row can no longer name Copenhagen. The column
+  cannot be a `parent`, since a table never reaches its own family; a test proves
+  every value names a row instead. A territory the register records no state for
+  stands alone, which is `EH` alone, and naming one for it would be a claim
+  fejkdata has no business making.
+- **`misc.loglevel` is a table keyed by the code, rendering POSIX's keyword.** A flat
+  list of names carries neither the code a PRI encodes nor a selector reaching it, and
+  goal 3 draws the two as one fact. The canonical spelling losing to the one its domain
+  writes, above, settles the rest: a configuration writes `info`, so RFC 5424's
+  `Informational` stays the `severity` column, and the code and the keyword hold the
+  two selector slots.
+- **`misc.tld` keys carry the leading dot, where other tables key on a bare code.**
+  The register spells a TLD `.se` and `misc.territory.tld` already ships it so, which a
+  bare key would make two spellings of one fact; `{/misc.tld}` also composes onto a
+  host with no separator. `misc.tld[se]` misses for it, which `todo.md` carries.
+- **`misc.tld` is a table of its own, and `misc.territory.tld` stays a column.** A
+  `parent` demands a child for every parent row, so linking them would drop every root
+  zone row naming no territory, which is most of them, and goal 12 holds a sourced
+  table whole. The loader refuses the link outright anyway: `tld` is a column of
+  `misc.territory`, and a table may not be named like a column of its ancestor.
+- **`misc.territory` carries a currency code, it does not link to `misc.currency`.**
   A `parent` demands a child for every parent row, and ISO 4217 registers codes no

+# Part 1 — Names, finance, company: sources and rules
+
+Researched 2026-09-17. "Embed" = ship as a data file in an MIT repo. Everything not marked UNVERIFIED was read from the cited page or file this session.
+
+## 1. US person names and identifiers
+
+### SSA baby names (given names by year and sex)
+- Page: https://www.ssa.gov/oact/babynames/limits.html — national zip https://www.ssa.gov/oact/babynames/names.zip (7 MB), state zip https://www.ssa.gov/oact/babynames/state/namesbystate.zip (23 MB), territories 228 kB.
+- Format (per SSA page + readme as mirrored by https://github.com/hackerb9/ssa-baby-names): one `yobYYYY.txt` per year 1880–2025, CSV `name,sex,count`, name 2–15 chars, sex `M`/`F`, sorted by sex then count desc. Names with < 5 occurrences in a year are excluded.
+- Counts: ~100,364 distinct names, ~2.02 M rows across all years (hackerb9 snapshot; year of snapshot UNVERIFIED). Top 1000 names cover 71.5 % of 2025 births (SSA page).
+- Licence: data.gov catalog entry https://catalog.data.gov/dataset/baby-names-from-social-security-card-applications-national-data lists licence **CC0 1.0** (`https://creativecommons.org/publicdomain/zero/1.0/`), publisher SSA. US federal work, no attribution required; embeddable.
+- Note: ssa.gov returns 403 to non-browser user agents (curl/WebFetch); download with a browser UA or via the data.gov link.
+
+### Census 2010 surnames
+- Page: https://www.census.gov/topics/population/genealogy/data/2010_surnames.html
+- Files: full set https://www2.census.gov/topics/genealogy/2010surnames/names.zip (CSV + XLSX, `Names_2010Census.csv`), top 1000 `Names_2010Census_Top1000.xlsx`, docs https://www2.census.gov/topics/genealogy/2010surnames/surnames.pdf.
+- Fields (from surnames.pdf): `name, rank, count, prop100k, cum_prop100k, pctwhite, pctblack, pctapi, pctaian, pct2prace, pcthispanic`. `(S)` = suppressed percentage. Names are UPPERCASE.
+- Count: 162,253 surnames occurring ≥ 100 times (covers 90.1 % of people with a recorded surname); the CSV also has a trailing `ALL OTHER NAMES` row (UNVERIFIED — www2.census.gov returned 403 to curl this session; download with a browser).
+- Licence: US Census Bureau work → US federal government work, public domain in the US (17 U.S.C. §105). Census only asks for citation (https://www.census.gov/about/policies/citation.html: "U.S. Census Bureau, [Table], [Product], [Vintage], [URL], accessed on [date]"). Embeddable; cite source in the data file header.
+
+### Name prefixes / suffixes
+- No authoritative enumerated list exists. USPS Publication 28 §33 (https://pe.usps.com/text/pub28/28c3_011.htm) defines the fields: Name Prefix, First Name, Middle Name or Initial, Surname, **Suffix Title** = "maturity (e.g., JR, SR) and professional (e.g., PHD, DDS) suffixes"; example "MR. WALTER W. WITHERSPOON JR.".
+- Recommendation: hand-curate. Prefixes `Mr., Mrs., Ms., Mx., Dr., Rev.`; suffixes `Jr., Sr., II, III, IV, PhD, MD, DDS, Esq.`. Rule of thumb: generational suffix (Jr/Sr/II–IV) only with a male name in traditional US usage; never combine Jr. with Sr.; at most one generational suffix.
+
+### SSN
+- Structure: `AAA-GG-SSSS` (area 3, group 2, serial 4). No check digit (Wikipedia).
+- Randomization since **2011-06-25** (https://www.ssa.gov/employer/randomization.html): "Previously unassigned area numbers were introduced for assignment excluding area numbers 000, 666 and 900-999." Area no longer geographic.
+- Invalid per SSA POMS RM 10201.035 (https://secure.ssa.gov/apps10/poms.nsf/lnx/0110201035): area `000`, `666`, `900–999`; group `00`; serial `0000`.
+- Generator rule: area ∈ [001,899] \ {666}; group ∈ [01,99]; serial ∈ [0001,9999].
+- Advertising SSNs (https://www.ssa.gov/history/ssn/misused.html): `078-05-1120` (Woolworth wallet card, 1938; > 40,000 people claimed it) and `219-09-9999` (1940 Social Security Board pamphlet). Both are structurally valid — exclude from output.
+- `987-65-4320`–`987-65-4329` "reserved for advertising": repeated by searchbug.com, ssn-check.org, a Missouri state standard (https://oa.mo.gov/sites/default/files/CC-SocialSecurityNumberNamingStandardV050305.pdf, which even misprints it as 987-54-4329). **UNVERIFIED** — not found on any ssa.gov page or POMS this session; Wikipedia no longer carries it. Safe to use these ten as the library's "obviously fake" examples, but do not cite SSA for it.
+
+### ITIN (IRS)
+- IRS Publication 4757 (Rev. 6-2026), p. 5 (https://www.irs.gov/pub/irs-pdf/p4757.pdf): "All valid ITINs are nine-digit numbers in the same format as the SSN (9XX-8X-XXXX), beginning with a "9" and the 4th and 5th digits ranging from 50 to 65, 70 to 88, 90 to 92, and 94 to 99."
+- Group `93` = ATIN (adoption TIN); `89` reserved (Intuit/TaxSlayer support pages, not IRS — UNVERIFIED).
+- Generator rule: `9` + 2 digits + group ∈ {50–65, 70–88, 90–92, 94–99} + 4 digits (serial `0000` not documented as invalid for ITIN; avoid it anyway).
+
+### EIN (IRS)

+### ABA routing number (RTN)
+- Wikipedia https://en.wikipedia.org/wiki/ABA_routing_transit_number: 9 digits; check: `(3(d1+d4+d7) + 7(d2+d5+d8) + (d3+d6+d9)) mod 10 = 0`.
+- First two digits: `00` US Government; `01–12` Federal Reserve districts (normal banks); `21–32` thrifts (historic, still valid); `61–72` non-bank payment processors/clearinghouses; `80` traveler's checks. Other prefixes unused (Wikipedia does not say so explicitly — inferred).
+- Generator rule: prefix ∈ {01–12, 21–32, 61–72}, 6 random digits, compute 9th as `(10 − (3d1+7d2+d3+3d4+7d5+d6+3d7+7d8) mod 10) mod 10`.
+- Open list of real RTNs: the Federal Reserve E-Payments Routing Directory (https://www.frbservices.org/resources/routing-number-directory/index.html) says "may not be sold, re-licensed, or otherwise used for commercial gain" → **not embeddable**. Generate synthetically.

+- CVV lengths: https://en.wikipedia.org/wiki/Card_security_code ("three-digit ... Visa, Mastercard, and Discover"; "American Express is a four-digit code on the front").
+- The requested "Maestro 50/56–58/6xxx" is a looser legacy rule; use Wikipedia's explicit IINs.
+- Wikipedia text is CC BY-SA 4.0 — copy the *facts* (not prose) into your table; facts are not copyrightable.
+
+### Published test cards
+- Stripe: https://docs.stripe.com/testing — Visa 4242424242424242, Mastercard 5555555555554444, Amex 378282246310005, Discover 6011111111111117, Diners 3056930009020004 (14), JCB 3566002020360505, UnionPay 6200000000000005; any future expiry, any CVC (4 for Amex).
+- PayPal: https://developer.paypal.com/tools/sandbox/card-testing/ — Visa 4005519200000004, 4012000033330026, 4012000077777777, 4012888888881881, 4217651111111119, 4500600000000061, 4772129056533503, 4915805038587737; Mastercard 2223000048400011; Amex 371449635398431, 376680816376961; Diners 36461510000039, 36461510000013; Maestro 6304000000000000, 5063516945005047; JCB 3636500000000260, 3636500000000989; CUP 6200680000000004, 6200680000000038.
+- Reuse: neither page carries an open licence (Stripe docs are under Stripe's site terms). The numbers themselves are Luhn-valid facts, widely reproduced; embedding the numbers with a "from Stripe/PayPal test docs" note is low-risk but **UNVERIFIED** as an explicit grant. Alternative: generate Luhn-valid numbers from the IIN table above — no dependency on either vendor.
+
+### BIC / SWIFT (ISO 9362)
+- https://en.wikipedia.org/wiki/ISO_9362: 4 letters bank code + 2 letters ISO 3166-1 country + 2 alphanumeric location + optional 3 alphanumeric branch (8 or 11 chars; `XXX` = primary office). Location second char `0` = test BIC, `1` = passive participant, `2` = reverse billing.
+- Generator rule: `[A-Z]{4}[A-Z]{2}[A-Z2-9][A-NP-Z0-9]([A-Z0-9]{3})?` — avoid `0`/`1` as the 8th char for a "live" BIC.
+- SWIFT's BIC Directory is proprietary (SwiftRef licence, redistribution needs a separate "SwiftRef Redistribution License": https://www.swift.com/myswift/ordering/order-products-services/swiftref-redistribution-license) → **not embeddable**.
+- Open alternative: GLEIF BIC-to-LEI mapping, https://www.gleif.org/en/lei-data/lei-mapping/download-bic-to-lei-relationship-files, files at https://mapping.gleif.org/api/v2/bic-lei/ (monthly zip; `LEI-BIC-20260828.zip` → `lei-bic-20260828T000000.csv`, columns `LEI,BIC`, 39,347 rows). Licence: "BIC/LEI Mapping Table License Agreement" (https://www.gleif.org/lei-data/lei-mapping/download-bic-to-lei-relationship-files/2017-12-21_annex-2_bic-to-lei-mapping-table-license-agreement_final.pdf) — a CC0-style grant "for any purpose whatsoever, including ... commercial" but **conditional on reproducing the notice** "SWIFT © and database rights [month year]. All rights reserved. This Mapping Table has been developed by SWIFT. Any use of the Mapping Table ... is subject to the BIC/LEI Mapping Table License Agreement ... For the latest BIC information and updates, always refer to www.swift.com/bic." Embeddable in an MIT repo with that notice in the data file; it is a list of real live BICs (bank names not included — join to GLEIF LEI data if names are wanted).
+
+### ISIN (https://en.wikipedia.org/wiki/International_Securities_Identification_Number)
+- 12 chars: 2-letter country + 9 alphanumeric NSIN + 1 check digit.
+- Check: convert letters A=10…Z=35 (ASCII − 55) to produce a digit string, then Luhn over that string (double every second digit from the right, sum digits, check makes total ≡ 0 mod 10). Pitfall: work on the *expanded* digit string; a transposed letter pair can pass.
+
+### CUSIP (https://en.wikipedia.org/wiki/CUSIP)
+- 9 chars: 6 issuer + 2 issue + 1 check. Values: digits as-is, A=10…Z=35, `*`=36, `@`=37, `#`=38.
+- Check: for i in 1..8, v = value; if i even, v ×= 2; sum += v div 10 + v mod 10; check = (10 − sum mod 10) mod 10.
+- Real CUSIPs are proprietary (CGS/FactSet); generate synthetic ones only.
+
+### IBAN (ISO 13616)
+- Validation (https://en.wikipedia.org/wiki/International_Bank_Account_Number): move first 4 chars to end, letters → 10–35, integer mod 97 must equal 1; max 34 chars; check digits 02–98.
+- SWIFT registry: https://www.swift.com/standards/data-standards/iban-international-bank-account-number, PDF release 101 https://www.swift.com/sites/default/files/files/iban-registry-v101.pdf (release 100 was Oct 2025); TXT also published (URL **UNVERIFIED** — swift.com returns 403/errors to automation this session). Terms: free of charge; no explicit licence text found (**UNVERIFIED**). Country count: 89 countries per Wikipedia (Dec 2024).
+- Embeddable per-country length tables already extracted from the registry:
+  - php-iban `registry.txt` (https://github.com/globalcitizen/php-iban, **LGPL-3.0**): pipe-separated, 121 rows (116 official + unofficial), columns `country_code|country_name|domestic_example|bban_example|bban_format_swift|bban_format_regex|bban_length|iban_example|iban_format_swift|iban_format_regex|iban_length|bban_bankid_start_offset|...|country_sepa|swift_official|...|currency_iso4217|central_bank_url|central_bank_name|membership`. LGPL data in an MIT repo is awkward; use it as a *reference* to build your own table (formats are facts) rather than copying the file.
+  - ibankit-js (https://github.com/koblas/ibankit-js, **Apache-2.0**, registry v95) — same caveat.
+  - Best route: own table `{country, length, bban_format}` derived from the SWIFT PDF (facts), cite SWIFT.
+
+### Currencies (ISO 4217)
+- ISO says use is free: https://www.iso.org/iso-4217-currency-codes.html — "ISO allows free-of-charge use of its country, currency and language codes from ISO 3166, ISO 4217 and ISO 639". Official list from SIX: https://www.six-group.com/dam/download/financial-information/data-center/iso-currrency/lists/list-one.xml (+ `.xls`, `list-three` historic). Fields `CtryNm, CcyNm, Ccy, CcyNbr, CcyMnrUnts`; published 2026-01-01; 280 entity rows, 178 distinct codes. No symbols. No licence text inside the XML.
+- Alternatives:
+  - datasets/currency-codes (https://github.com/datasets/currency-codes): **PDDL** (public domain); `data/codes-all.csv` fields `Entity, Currency, AlphabeticCode, NumericCode, MinorUnit, WithdrawalDate`; built from SIX list one + three; no symbols. Embeddable.
+  - npm `currency-codes` v2.2.0 (https://github.com/freeall/currency-codes): **MIT**; fields `code, number, digits, currency, countries[]`; generated from the SIX XML; no symbols. Embeddable.
+  - umpirsky/currency-list (https://github.com/umpirsky/currency-list): **MIT**; code → localised name only (311 entries in `data/en_US/currency.json`, includes historic); no symbols, no numeric codes, no decimals.
+  - Debian iso-codes (https://salsa.debian.org/iso-codes-team/iso-codes): **LGPL-2.1+**; `data/iso_4217.json` has `alpha_3, name, numeric` only (179 entries); no symbols/minor units. LGPL → avoid embedding.
+  - Symbols: none of the above carry them. Unicode CLDR (`common/main/en.xml` currency symbols, Unicode License, MIT-compatible with notice) is the usual source — **UNVERIFIED this session**.
+
+### Crypto addresses
+- Bitcoin (https://en.bitcoin.it/wiki/List_of_address_prefixes): P2PKH version 0x00 → leading `1`; P2SH 0x05 → leading `3`; Base58Check 25–34 chars (alphabet excludes `0OIl`; last 4 bytes = first 4 of double-SHA256 of version+payload). Testnet `m`/`n`, `2`, `tb1`.
+- Bech32 (BIP-173, https://github.com/bitcoin/bips/blob/master/bip-0173.mediawiki, BSD-2-Clause): HRP `bc`, separator `1`, charset `qpzry9x8gf2tvdw0s3jn54khce6mua7l`, all-lowercase (or all-uppercase), max 90 chars; P2WPKH `bc1q…` = 42 chars, P2WSH `bc1q…` = 62 chars.
+- Bech32m (BIP-350, https://github.com/bitcoin/bips/blob/master/bip-0350.mediawiki): witness v1+ (P2TR `bc1p…`, 62 chars), checksum constant `0x2bc830a3` instead of 1.
+- Ethereum EIP-55 (https://eips.ethereum.org/EIPS/eip-55, CC0): `0x` + 40 hex; keccak256 of the lowercase hex (no 0x, as ASCII); for each hex letter, uppercase iff the corresponding hash nibble ≥ 8 (bit 4·i set). Digits unchanged.
+
+## 3. Company
+
+### NAICS 2022 (US Census)
+- Page https://www.census.gov/naics/ ; files: 6-digit list https://www.census.gov/naics/2022NAICS/6-digit_2022_Codes.xlsx (82 kB; **1,012** six-digit codes, 111110…928120, verified by parsing), 2–6 digit https://www.census.gov/naics/2022NAICS/2-6%20digit_2022_Codes.xlsx, structure https://www.census.gov/naics/2022NAICS/2022_NAICS_Structure.xlsx, descriptions https://www.census.gov/naics/2022NAICS/2022_NAICS_Descriptions.xlsx, manual PDF https://www.census.gov/naics/reference_files_tools/2022_NAICS_Manual.pdf.
+- Format: xlsx, column A code (numeric), column B title (trailing spaces in some titles — trim).
+- Licence: no statement on the page or in the manual front matter; US federal government work → public domain in the US (17 U.S.C. §105). Embeddable; cite Census/OMB.
+
+### SEC EDGAR company names
+- `https://www.sec.gov/files/company_tickers.json`: object keyed `"0".."N"` of `{cik_str, ticker, title}`; **10,422** entries (2026-09-17). `company_tickers_exchange.json`: `{"fields":["cik","name","ticker","exchange"],"data":[...]}`.
+- `https://www.sec.gov/Archives/edgar/cik-lookup-data.txt`: 40 MB, **1,059,372** lines, `NAME:CIK:` (`COMPANY NAME:0001234567:`), all filers incl. individuals — filter to the ticker list for company names.
+- Access: declare `User-Agent: Company Name email@domain`, ≤ 10 req/s (https://www.sec.gov/os/webmaster-faq). Licence: "All Government-created content on sec.gov and EDGAR public filing content are free to access and reuse" (same FAQ). Embeddable; the ticker file (~800 kB) is the practical one.
+
+### DUNS
+- https://en.wikipedia.org/wiki/Data_Universal_Numbering_System: 9 digits, no significance; shown `NN-NNN-NNNN` or plain. Had a mod-10 check digit until ~Dec 2006; **dropped** since (expanded the pool by 800 M). So: any 9 digits are structurally valid today; no validation rule to enforce. Optional DUNS+4 suffix (4 alphanumerics) is user-assigned.
+
+### Legal entity suffixes per country
+- GLEIF ISO 20275 Entity Legal Forms code list v1.6 (2026-02-19): page https://www.gleif.org/en/lei-data/code-lists/iso-20275-entity-legal-forms-code-list ; CSV https://www.gleif.org/lei-data/code-lists/iso-20275-entity-legal-forms-code-list/2026-02-19-elf-code-list-v1.6.csv (758 kB; xlsx alongside).
+- Columns: `ELF Code, Country of formation, Country Code (ISO 3166-1), Jurisdiction of formation, Country sub-division code (ISO 3166-2), Entity Legal Form name Local name, Language, Language Code (ISO 639-1), Entity Legal Form name Transliterated name, Abbreviations Local language, Abbreviations transliterated, Date created, ELF Status ACTV/INAC, Modification, Modification date, Reason`.
+- Counts: 4,002 rows; 130 countries; 3,790 ACTV / 212 INAC; 1,518 rows have a local abbreviation (e.g. US `N.A.`, `FSA`; SE `AB`… multiple abbreviations separated by `;`). US has 737 rows (per-state forms). Abbreviations are the field you want for `Inc`, `LLC`, `GmbH`, `AB`, `SAS`, `Pty Ltd`; many rows have none, so filter on non-empty abbreviation and status ACTV.
+- Licence: GLEIF Open Data page (https://www.gleif.org/en/about/open-data): "The data on GLEIF's website is provided under a Creative Commons (CC0) license"; LEI Data Terms of Use: "provided under the CC0 licence, see CC0 1.0 Universal". The ELF page itself names no licence — that CC0 explicitly covers this code list is **UNVERIFIED**, but GLEIF treats all its published data this way. Embeddable.

+### IANA registries (all of them)
+- Licence: IANA/IETF statement at https://www.iana.org/help/licensing-terms — "IANA and IETF intend that the Protocol Registries may be freely used by any party for any purpose", data dedicated under **CC0 1.0**. No attribution required. **EMBED**.
+- All registries below share this licence; ship one `SOURCES`/NOTICE line pointing at that URL.

Template is the full `type/subtype`; some rows are DEPRECATED/OBSOLETED in Name (filter). Format: RFC 6838 §4.2 — `type "/" subtype`, restricted chars, max 127 chars each, case-insensitive. |

+
+### MIME extension mapping: jshttp/mime-db
+- https://github.com/jshttp/mime-db — **MIT** (GitHub API spdx MIT; npm `license: MIT`), version 1.54.0 on npm.
+- `db.json` (CDN: https://cdn.jsdelivr.net/npm/mime-db/db.json): object keyed by lower-case type → `{source, extensions[], compressible, charset}`.
+- Counts (1.54.0): **2,522 types**, **1,015 with extensions**; source = iana 2,136, apache 275, nginx 13, custom 98.
+- Sources: IANA registry (CC0), Apache httpd `mime.types` (Apache-2.0), nginx `mime.types` (BSD-2). **EMBED+ATTR** (keep the MIT copyright notice). Data updates are not semver-breaking per README.
+
+### IPv4 / IPv6 generation rules (RFCs, no data file needed)
+- RFC 5737 documentation: `192.0.2.0/24` (TEST-NET-1), `198.51.100.0/24` (TEST-NET-2), `203.0.113.0/24` (TEST-NET-3). https://www.rfc-editor.org/rfc/rfc5737.html
+- RFC 1918 private: `10.0.0.0/8`, `172.16.0.0/12`, `192.168.0.0/16`. Also useful: `100.64.0.0/10` CGNAT (RFC 6598), `198.18.0.0/15` benchmarking (RFC 2544), `169.254.0.0/16` link-local.
+- IPv6 documentation: `2001:db8::/32` (RFC 3849) and `3fff::/20` (RFC 9637, "expands on the existing 2001:db8::/32 … with the reservation of an additional, larger prefix"). ULA `fc00::/7` (use `fd00::/8`), link-local `fe80::/10`.
+- Validation: generate inside those blocks; avoid network/broadcast (`.0`/`.255`) if the consumer expects host addresses. Format IPv6 per RFC 5952 (lower-case hex, `::` once, longest zero run).
+
+### MAC OUI (IEEE MA-L)
+- CSV: https://standards-oui.ieee.org/oui/oui.csv (3.8 MB, **40,161 rows**, fields `Registry,Assignment,Organization Name,Organization Address`; Assignment is 6 hex chars). Server returns HTTP 418 to non-browser user agents; fetch with a browser UA. Also MA-M `oui28.csv`, MA-S `oui36.csv`, CID `cid.csv`.
+- Licence: no licence on the IEEE pages themselves (site footer "© IEEE – All rights reserved" is generic). Debian's `ieee-data` copyright file (https://metadata.ftp-master.debian.org/changelogs/main/i/ieee-data/unstable_copyright) records IEEE's 2014 statement: *"IEEE does not assert any copyright in the OUI Public Listing or attempt to restrict distribution of the listing in any way. The IEEE Registration Authority does, however, strongly encourage those who use the list to obtain it directly from IEEE…"* — same text in the FSF directory. Debian ships it in `main` on that basis. **EMBED+ATTR** (cite the statement); the org-address column is not needed — keep `Assignment,Organization Name` only (~1 MB → few hundred KB). UNVERIFIED: no current IEEE page restates it (regauth FAQ and IPR pages do not mention it).
+- Alternative needing no data: locally administered unicast MAC — first octet's bit 1 (U/L) = 1, bit 0 (I/G) = 0 → second hex digit ∈ {2, 6, A, E}, e.g. `x2:xx:xx:xx:xx:xx`. Guaranteed never to collide with a vendor OUI. Notations: `01:23:45:67:89:ab`, `01-23-45-67-89-AB`, Cisco `0123.4567.89ab`.

+- None of the above is CC0. Alternative: generate UAs from templates (Chrome/Firefox/Safari/Edge strings are fixed-form; only version numbers vary), no data needed.
+
+### Programming languages: GitHub Linguist
+- https://raw.githubusercontent.com/github-linguist/linguist/main/lib/linguist/languages.yml — **MIT** (repo LICENSE, "Copyright (c) 2017 GitHub, Inc."). **EMBED+ATTR**.
+- **835** top-level entries; **562** with `type: programming` (others: data, markup, prose). Per-entry fields: `type, color, extensions, aliases, tm_scope, ace_mode, language_id, group, interpreters, …`.
+
+### Operating systems
+- No open dataset found beyond awesome-lists. OS names/versions are facts — hand-author a small table (Windows 10/11, Windows Server, macOS versions+names, Ubuntu/Debian/Fedora/Arch/Alpine, iOS, Android, FreeBSD…). `user-agents` (BSD-2) carries `platform`/`oscpu` values if a data-driven list is wanted.
+
+### Database engines / collations
+- Engine names: hand-author (facts).
+- MySQL manual (https://dev.mysql.com/doc/refman/8.4/en/preface.html): Oracle terms — "you may not … copy, reproduce … distribute … any part" except distributing the docs with the software. **AVOID copying tables from MySQL docs.** Instead dump `SHOW COLLATION` from a `mysql:8.4.x` container (server output is factual, not the manual) — ~286 collations / 41 charsets in 8.x (UNVERIFIED count). PostgreSQL docs are under the PostgreSQL licence (permissive, keep notice) — `pg_collation` dump or docs both fine. MariaDB KB is CC BY-SA — avoid.
+
+## 5. Vehicle
+
+### NHTSA vPIC
+- API base `https://vpic.nhtsa.dot.gov/api/vehicles/`, `?format=json|xml|csv`. Endpoints verified: `GetAllMakes` (**12,363 makes**, fields `Make_ID,Make_Name`; 612 KB JSON, mostly small trailer/custom builders — filter with `GetMakesForVehicleType/car` → 195 makes, `/truck` → 207), `GetModelsForMake/honda` (362 models, `Make_ID,Make_Name,Model_ID,Model_Name`), `DecodeWMI/1HG`, `GetWMIsForManufacturer/honda` (45 WMIs, fields `WMI,Name,Country,VehicleType,Id,…`), `GetVehicleVariableList`, `GetVehicleVariableValuesList/<display name>` (must be the display name, URL-encoded, e.g. `Fuel%20Type%20-%20Primary`; the camel-case name returns 0 rows).
+- Value lists (counts): **Fuel Type - Primary 14**, **Body Class 71**, **Transmission Style 12**, **Drive Type 23**, **Vehicle Type 9**. Fields `Id,Name`.
+- Bulk: https://vpic.nhtsa.dot.gov/downloads/ — `vPICList_lite_2026_08.bak.zip` (MS SQL Server 2019+ backup, 190 MB, updated 2026-08-14), also `.plain.zip` / `.custom.zip`. Page says standalone DB "limited to VIN decoding"; makes/models/variables still via API. Contains `Wmi`, `Make`, `Model`, `WMIYearValidChars` tables (UNVERIFIED table names).
+- Licence: FAQ https://vpic.nhtsa.dot.gov/api/home/index/faq — "No, NHTSA is a government agency and the services provided on the API are free for use by the public as an offering as a part of our Open Data initiatives"; no rate-limit number stated, batch jobs asked to run at night. Work of the US federal government → public domain under 17 USC §105; data.gov entry lists licence as "unknown". **EMBED** (note source; no attribution legally required).
+
+### VIN (ISO 3779 / 49 CFR 565, North America)
+- 17 chars from `0-9 A-H J-N P R-Z` (**I, O, Q never**). Positions: 1–3 WMI, 4–8 VDS, 9 check digit, 10 model year, 11 plant, 12–17 serial (last 4 must be digits for US, positions 12–14 alphanumeric — 49 CFR 565.15).
+- Check digit: transliterate `A=1 B=2 C=3 D=4 E=5 F=6 G=7 H=8 J=1 K=2 L=3 M=4 N=5 P=7 R=9 S=2 T=3 U=4 V=5 W=6 X=7 Y=8 Z=9`, digits as-is; weights `8 7 6 5 4 3 2 10 0 9 8 7 6 5 4 3 2`; sum mod 11 → digit, remainder 10 → `X`.
+- Model year (pos 10): excludes `I O Q U Z 0`; `A=2010 … H=2017 J=2018 K=2019 L=2020 M=2021 N=2022 P=2023 R=2024 S=2025 T=2026 V=2027 W=2028 X=2029 Y=2030`, `1=2031…9=2039` (30-year cycle; `1–9` also = 2001–2009).

NLM policy (https://www.ncbi.nlm.nih.gov/home/about/policies/): "Information that is created by or for the US government on this site is within the public domain … may be freely distributed and copied. However, it is requested that in any subsequent use of this work, NLM be given appropriate acknowledgment." | Yes; add an acknowledgment line ("Element data: PubChem/NLM"). | `AtomicNumber, Symbol, Name, AtomicMass, CPKHexColor, ElectronConfiguration, Electronegativity, AtomicRadius, IonizationEnergy, ElectronAffinity, OxidationStates, StandardState, MeltingPoint, BoilingPoint, Density, GroupBlock, YearDiscovered` (17) | 118 (Z=1..118, verified) | CSV; JSON is `{Table:{Columns:{Column:[...]},Row:[{Cell:[...]}]}}` |
+| NIST periodic table https://www.nist.gov/pml/periodic-table-elements | Public domain (17 USC 105); NIST asks for citation (https://www.nist.gov/open/copyright-fair-use-and-licensing-statements-srd-data-software-and-technical-series-publications) | Yes, but | PDF only (no CSV/JSON) — not usable as a data source | 118 | PDF |
+| Bowserinator/Periodic-Table-JSON https://github.com/Bowserinator/Periodic-Table-JSON | **CC BY-SA 3.0** (LICENSE.md, verified; data derived from Wikipedia) | **No** — ShareAlike is incompatible with MIT redistribution | 33 keys incl. `name, symbol, number, atomic_mass, category, phase, period, group, block, shells, electron_configuration, summary, cpk-hex, …` | **119** (includes hypothetical Ununennium) | JSON, CSV |

+Validation rules: `AtomicNumber` 1..118 unique; `Symbol` 1–2 letters, first uppercase, unique; `Name` unique. PubChem leaves numeric fields empty for Z≥104 where unknown; `ElectronConfiguration` for Og is `"[Rn]7s2 7p6 5f14 6d10 (predicted)"` and `StandardState` is `"Expected to be a Gas"` — strip "(predicted)"/"Expected to be a" if you want an enum. `AtomicMass` for unstable elements is the mass number of the most stable isotope as a bare decimal (e.g. `295.216`), no brackets. `CPKHexColor` is 6 hex digits without `#`, empty for some.

+### SI units
+
+- Source: BIPM SI Brochure, 9th ed. (2019; current revision v4.01, 2026) https://www.bipm.org/en/publications/si-brochure ; PDF https://www.bipm.org/documents/20126/41483022/SI-Brochure-9-EN.pdf
+- Licence: **CC BY 4.0** — stated on the brochure page and on BIPM's copyright page (https://www.bipm.org/en/copyright): content may be adapted, copied, used in commercial products with "appropriate acknowledgement of the BIPM and its source"; BIPM name/logo must not imply endorsement. Verified via the HTML pages; the PDF's own front-matter licence line is **UNVERIFIED** (could not text-extract the PDF here).
+- Embed: Yes — the unit *names/symbols* are facts (not copyrightable); attribute "SI Brochure, BIPM, CC BY 4.0" anyway.
+- Data (cross-checked against https://en.wikipedia.org/wiki/International_System_of_Units):
+  - 7 base units: second s (time), metre m (length), kilogram kg (mass), ampere A (electric current), kelvin K (thermodynamic temperature), mole mol (amount of substance), candela cd (luminous intensity).
+  - 22 coherent derived units with special names: radian rad, steradian sr, hertz Hz, newton N, pascal Pa, joule J, watt W, coulomb C, volt V, farad F, ohm Ω, siemens S, weber Wb, tesla T, henry H, degree Celsius °C, lumen lm, lux lx, becquerel Bq, gray Gy, sievert Sv, katal kat.
+  - 24 prefixes: quetta Q 10^30, ronna R 10^27, yotta Y 10^24, zetta Z 10^21, exa E 10^18, peta P 10^15, tera T 10^12, giga G 10^9, mega M 10^6, kilo k 10^3, hecto h 10^2, deca da 10^1, deci d 10^-1, centi c 10^-2, milli m 10^-3, micro µ 10^-6, nano n 10^-9, pico p 10^-12, femto f 10^-15, atto a 10^-18, zepto z 10^-21, yocto y 10^-24, ronto r 10^-27, quecto q 10^-30.
+- Format rules for valid output: unit symbols are case-sensitive (`s` vs `S`, `m` vs `M`); prefix and unit symbol are joined without a space (`kJ`, `µs`); a space separates number and unit (`12 kg`), except the degree/minute/second of plane angle; `kg` already carries a prefix — never `µkg`; micro is Greek mu U+03BC (U+00B5 micro sign is the legacy compatibility character); ohm is U+03A9 (U+2126 OHM SIGN is deprecated); `°C` not `° C`.
+- MIT alternative: faker-js `en/science/unit.ts` — 29 `{name, symbol}` objects, MIT.
+
+### Animals by class
+
+- **Wikidata** (https://www.wikidata.org/wiki/Wikidata:Licensing): all structured data **CC0** — no attribution required. Embed: Yes.
+  - Feasibility, live SPARQL (https://query.wikidata.org/sparql), pattern `?t wdt:P31 wd:Q16521; wdt:P105 wd:Q7432; wdt:P171* wd:<class>; wdt:P1843 ?cn FILTER(LANG(?cn)='en')` (taxon, rank species, parent-taxon chain, English common name):
+    - Mammalia Q7377: **5,759** species with ≥1 English common name.
+    - Aves Q5113: **12,432**.
+    - Reptilia Q10811: **16,369** — suspiciously large; Wikidata's parent chain likely pulls birds/Sauropsida in. Use Squamata Q122422 + Testudines Q223044 + Crocodilia Q1387 (or check the chain) instead.
+    - Insecta Q1390 and Plantae Q756: **timed out (502/504) every attempt** — trees too big for the 60 s public endpoint. Options: paginate by order (`P171` one level at a time), use the weekly JSON dump, or take GBIF instead.
+  - Sample rows (mammals): `Notoryctes typhlops` → "Central Desert Marsupial Mole", "Itjaritjari", "Marsupial Mole", "Southern marsupial mole", "Southern Marsupial Mole" — i.e. **several P1843 values per taxon, inconsistent casing, and indigenous-language names tagged `en`**. Validation: pick one name per taxon (prefer the one matching the item's English `rdfs:label`), normalise case, drop names that equal the scientific name.
+- **GBIF Backbone Taxonomy** https://www.gbif.org/dataset/d7dddbf4-2cf0-4f39-9b2a-bb099caae36c — licence **CC BY 4.0** (verified via https://api.gbif.org/v1/dataset/d7dddbf4-2cf0-4f39-9b2a-bb099caae36c, `license: http://creativecommons.org/licenses/by/4.0/legalcode`); required citation text: "GBIF Secretariat (2023). GBIF Backbone Taxonomy. Checklist dataset https://doi.org/10.15468/39omei". Embed: Yes with that citation. Vernacular names come via `/v1/species/{key}/vernacularNames`, each row from a *different* source checklist with its own licence (some CC BY-NC) — record and check per row. GBIF's site terms page (https://www.gbif.org/terms) was unreachable (timeout) — **UNVERIFIED** beyond the API field.
+- **faker-js** `src/locales/en/animal/*` (MIT; counts = quoted string lines on branch `next`): bird 821, snake 533, dog 493, cow 467, horse 342, rodent 161, insect 129, fish 95, cat 55, cetacean 52, rabbit 49, type 44 (generic: "bat, bear, bee, …, zebra"), pet_name 42, crocodilia 24, bear 8, lion 7. These are breeds/species mixed with common names, no class field; fine as MIT drop-ins. (A WebFetch summariser claimed 1,036 dogs; the regex count is 493 — treat the exact count as UNVERIFIED.)
+
+### Plants
+
+- Same Wikidata approach (CC0) — but the Plantae query timed out; paginate by order or family (`?t wdt:P171 ?family . ?family wdt:P105 wd:Q35409`) or use the dump.
+- GBIF Plantae (kingdomKey 6) vernacular names, CC BY 4.0, same per-row-licence caveat.
+- faker-js has **no** plant list (en locale dirs: airline, animal, app, book, color, commerce, company, database, date, finance, food, hacker, internet, location, lorem, medical, music, person, phone_number, science, team, vehicle, word).
+- USDA PLANTS database (public domain, has common names) — **UNVERIFIED**, not fetched.
+
+### Planets / moons
+
+- NASA NSSDCA Planetary Fact Sheet https://nssdc.gsfc.nasa.gov/planetary/factsheet/ — 10 columns (Mercury, Venus, Earth, Moon, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto) × 20 rows (mass 10^24 kg, diameter km, density, gravity, escape velocity, rotation period, day length, distance from Sun, perihelion, aphelion, orbital period, orbital velocity, inclination, eccentricity, obliquity, mean temp °C, surface pressure, number of moons, rings Y/N, magnetic field Y/N). HTML table only. NASA content "generally not subject to copyright in the United States" (https://www.nasa.gov/nasa-brand-center/images-and-media/); NASA asks to be acknowledged; the NASA insignia must not be used.

+- Wikidata (CC0): planets = `?p wdt:P31/wdt:P279* wd:Q634; wdt:P397 wd:Q525` → Mercury Q308, Venus Q313, Earth Q2, Mars Q111, Jupiter Q319, Saturn Q193, Uranus Q324, Neptune Q332 (plus hypothetical Theia Q1053432 — filter out). Moons = `?m wdt:P397 <planet>; wdt:P31/wdt:P279* wd:Q2537` (natural satellite; note **Q2199 is "dwarf planet"**, not moon): Saturn 165, Jupiter 85, Uranus 29, Neptune 16, Earth 5, Mars 2. Caveats: Wikidata lags IAU counts (Saturn has 274 recognised moons as of 2025 — UNVERIFIED figure); Earth's 5 includes quasi-satellites; provisional designations (`S/2004 S 3`) are labels too — filter `^S/\d{4}` if you want proper names only.

+### Blood type distribution
+
+- **US** (Stanford Blood Center https://stanfordbloodcenter.org/donate-blood/blood-donation-facts/blood-types/, verified; cites AABB Technical Manual 18th ed.): O+ 37.4 %, A+ 35.7 %, B+ 8.5 %, AB+ 3.4 %, O− 6.6 %, A− 6.3 %, B− 1.5 %, AB− 0.6 % (sums to 100.0). Facts — freely embeddable; cite Stanford/AABB.
+- American Red Cross https://www.redcrossblood.org/donate-blood/blood-types.html — **UNVERIFIED**: site returns HTTP 403 (Akamai) to both WebFetch and the headless browser. Search snippets say the Red Cross gives type O by ethnicity (Latino 57 %, African American 51 %, Caucasian 45 %) rather than an 8-way national table.
+- **Global**: no authoritative figure found. Wikipedia "Blood type distribution by country" gives a population-weighted row (O+ 38.4, A+ 27.3, B+ 8.1, AB+ 2.0, O− 13.1, A− 8.1, B− 2.0, AB− 0.01) that its own editors flag "unreliable source"; WorldAtlas gives O+ 42, A+ 31, B+ 15, AB+ 5, O− 3, A− 2.5, B− 1, AB− 0.5 with no source. Recommend shipping only the US table, or per-country tables from Wikipedia (facts; Wikipedia prose is CC BY-SA but the numbers are cited to national blood services — cite those).
+- Validation: ABO ∈ {A, B, AB, O}; Rh ∈ {+, −}; weights must sum to 100 ± rounding.

+- Either Bartlett text needs parsing (quote / author / source headings); no structured file. Wikiquote is CC BY-SA — avoid.
+- Validation: strip Gutenberg header/footer (`*** START OF THE PROJECT GUTENBERG EBOOK` … `*** END …`) before extraction; Gutenberg's trademark terms only bind if you keep the "Project Gutenberg" name on the output — strip it.

+- Source https://www.iana.org/time-zones ; files https://data.iana.org/time-zones/tzdb/ (current version **2026d**, verified). LICENSE: "Unless specified below, all files in the tz code and data (including this LICENSE file) are in the public domain" (only `date.c`, `newstrftime.3`, `strftime.c` are BSD-3). Embed: Yes, no notice needed.
+- `zone1970.tab` — **312** data rows; tab-separated; UTF-8; `#` comments. Columns: (1) comma-separated ISO 3166-1 alpha-2 codes of countries overlapping the zone, most-populous first; (2) coordinates in ISO 6709 `±DDMM±DDDMM` or `±DDMMSS±DDDMMSS` (lat then lon, no separator); (3) TZ name (`Europe/Zurich`); (4) comment, present iff the country has several zones. One row per timezone where civil time has agreed since 1970.
+- `zone.tab` — **418** rows, older one-country-per-row table (column 1 is a single country code); kept for backward compatibility. Prefer `zone1970.tab`.
+- `backward` — **252** `Link TARGET LINK-NAME` lines mapping old/merged names (`US/Eastern`, `Asia/Calcutta`, `Europe/Kiev`) to current ones; also a few `Zone` entries. Use it to (a) accept aliases as input and (b) never emit them as output.
+- UTC offsets: do **not** embed — offsets depend on DST rules that change several times a year. Derive at runtime: `new Intl.DateTimeFormat('en-US', { timeZone, timeZoneName: 'longOffset' }).formatToParts(date)` → part `timeZoneName` = `GMT-05:00` (or `GMT` for zero) — strip `GMT`, treat bare `GMT` as `+00:00`. Validation of a generated zone name: `Intl.supportedValuesOf('timeZone')` (canonical names only; whether links like `US/Eastern` appear depends on the ICU build) or `try { new Intl.DateTimeFormat(undefined, { timeZone }) } catch { invalid }`, which accepts links too.

+| Week date | `YYYY-Www-D` | `YYYYWwwD` | 2009-W01-1 (weeks start Monday, week 1 contains 4 Jan) |
+| Time | `hh:mm:ss[.fff]` | `hhmmss` | 13:47:30 (24 h; `T` prefix optional standalone) |
+| UTC / offset | `Z` or `±hh:mm` | `±hhmm`, `±hh` | 2007-04-05T14:30Z, 2024-06-01T09:00-05:00 |
+| Date-time | date `T` time offset | | 2007-04-05T14:30:00+02:00 |

+| Interval | start`/`end, start`/`duration, duration`/`end | | 2007-03-01T13:00:00Z/2008-05-11T15:30:00Z |
+| Recurring | `Rn/`interval | | R5/2008-03-01T13:00:00Z/P1Y2M10DT2H30M |
+
+RFC 3339 profile (what JSON/APIs usually mean): extended forms only, `T`/`Z` may be lowercase, space allowed instead of `T`, `-00:00` = unknown offset, no durations/intervals/week/ordinal dates. Generate RFC 3339 by default.

+
+- Licence: **Unicode License v3** (SPDX `Unicode-3.0`), OSI-approved 2023-11-17 (https://opensource.org/license/unicode-3-0). Text https://www.unicode.org/license.txt — MIT-style: use/copy/modify/sell "provided that either (a) this copyright and permission notice appear with all copies of the Data Files or Software, or (b) this copyright and permission notice appear in associated Documentation"; no use of the Unicode name in advertising. Embed: Yes; put the notice in LICENSE/NOTICE.
+- npm: `cldr-core`, `cldr-dates-full`, `cldr-numbers-full` (peer of dates), etc.; current **48.2.0** (CLDR 48, verified via npm registry, `license: Unicode-3.0`); repo https://github.com/unicode-org/cldr-json .
+- Path is **`cldr-dates-full/main/<locale>/ca-gregorian.json`** (not `dates/gregorian.json`), rooted at `main.<locale>.dates.calendars.gregorian`. Keys (verified for `en`): `months`, `days`, `quarters`, `dayPeriods`, `eras`, `dateFormats`, `dateSkeletons`, `timeFormats`, `timeSkeletons`, `dateTimeFormats`, `dateTimeFormats-atTime`, `dateTimeFormats-relative`.
+  - `months.{format|stand-alone}.{abbreviated|narrow|wide}` keyed `"1".."12"`; `days.{format|stand-alone}.{abbreviated|narrow|short|wide}` keyed `sun..sat`.
+  - `dateFormats`: en = full `EEEE, MMMM d, y`, long `MMMM d, y`, medium `MMM d, y`, short `M/d/yy`.
+  - `timeFormats`: en = full `h:mm:ss a zzzz`, long `h:mm:ss a z`, medium `h:mm:ss a`, short `h:mm a` — **the `a` is preceded by U+202F NARROW NO-BREAK SPACE**; `*-alt-ascii` variants use a plain space. Pick one spelling (ASCII) and ignore the other.
+  - `dateTimeFormats.{full|long|medium|short}` = glue like `{1}, {0}` ({1} date, {0} time); `availableFormats` = skeleton→pattern map (`yMMMd` → `MMM d, y`), plus `intervalFormats`, `appendItems`.
+  - `dayPeriods.format.abbreviated`: `am: AM`, `pm: PM`, plus `midnight`, `noon`, `morning1`… variants.
+- Pattern letters follow LDML (https://unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table): `y` year, `M`/`L` month (format/stand-alone), `d` day, `E`/`c` weekday, `h` 1–12, `H` 0–23, `a` AM/PM, `z`/`zzzz` zone name, `x`/`X` ISO offset; literal text in single quotes. Same patterns drive `Intl.DateTimeFormat` internally, so runtime `Intl` can replace embedding for month/weekday names if bundle size matters.

+- Flag emoji: derive, no data needed — for alpha-2 `XY`, emit U+1F1E6 + (X − 'A') and U+1F1E6 + (Y − 'A') (regional indicator symbols).
+- Recommendation: `datasets/country-codes` (PDDL) covers every requested field (name, alpha2, alpha3, numeric, calling code, TLD, capital, currency, languages) in one CSV; flag emoji derived. `annexare` (MIT) is the fallback for native names/calling codes if PDDL's ISO caveat worries you; it lacks TLD.
+- Validation rules: alpha-2 `^[A-Z]{2}$`, alpha-3 `^[A-Z]{3}$`, numeric `^\d{3}$` (zero-padded, keep as string); calling code 1–3 digits, NANP countries share `1`; TLD `^\.[a-z]{2}$` (ccTLD = lowercase alpha-2, exceptions: GB uses `.uk`).

+- Rules: 639-1 `^[a-z]{2}$`, 639-2/3 `^[a-z]{3}$`; 639-2 has B/T pairs (e.g. `fre`/`fra`, `ger`/`deu`) — pick one consistently (T codes = 639-3).

UNVERIFIED how much is derived from each | "all countries and regions" (count not stated) | ISO 3166-2 + FIPS codes, names in 12 languages, admin level, GeoNames/OSM/Wikipedia/WOF ids |

+
+- Recommendation: for an en_US library, ship only the US list (Census/USPS, public domain: 50 states + DC, optionally territories) — ISO 3166-2 code = `US-` + USPS abbreviation. Skip the ~5000-row world list; every open compilation is LGPL, CC BY-SA or unclear.
+- Rule: `^[A-Z]{2}-[A-Z0-9]{1,3}$`.

+## 11. Commerce

+### Word lists (product name / adjective / material)
+
+- [@faker-js/faker](https://github.com/faker-js/faker) 10.6.0 — MIT (LICENSE covers code and locale data; copyright Faker contributors 2022-2025 and Marak Squires 2011-2020; acknowledges Ruby Faker and Perl Data::Faker, both MIT). No separate data licence.
+- Provenance policy in [CONTRIBUTING.md](https://github.com/faker-js/faker/blob/next/CONTRIBUTING.md): "Faker must not contain copyrighted materials"; facts (finite known lists) are OK; compilations must not be copied from a single source (Wikipedia, "most popular" articles, government sites) because "a compilation of facts can be copyrighted" — contributors are told to draw on multiple sources and their own judgement.
+- Verdict: reusing faker's `en` commerce lists (`product_name.adjective/material/product`, `department`) is fine under MIT — keep the MIT notice with the copied data. The lists are short curated words (no external dataset). Nothing in the repo or docs restricts locale-data reuse beyond MIT.
+
+### Garment and shoe sizes
+
+- Letter sizes XS–XXL: EN 13402-3 letter codes with chest/bust ranges (Wikipedia [EN 13402](https://en.wikipedia.org/wiki/EN_13402), CC BY-SA — but the table is a handful of facts; the standard itself is paywalled). Men chest / women bust cm: XXS 70–78 / 66–74, XS 78–86 / 74–82, S 86–94 / 82–90, M 94–102 / 90–98, L 102–110 / 98–107, XL 110–118 / 107–119, XXL 118–129 / 119–131, 3XL 129–141 / 131–143.
+- US numeric women's sizes (0–20, even) come from ASTM D5585 (paywalled); no open dataset. Just generate the even-number series.
+- Shoe sizes: no open dataset found (search hits are ML demos and retailer charts). Use the formulas from Wikipedia [Shoe size](https://en.wikipedia.org/wiki/Shoe_size) (facts, not copyrightable): EU (Paris point) ≈ 1.5 × foot cm + 2 (i.e. 3/20 × mm + 2); UK adult ≈ 3 × foot in − 23; US men ≈ 3 × foot in − 22 = UK + 1; US women (common) = US men + 1.5 (FIA scale: 3 × foot in − 21); Mondopoint = foot length mm. ISO/TS 19407:2023 has the official conversion tables (paywalled). Generate from a foot length (men 24–31 cm, women 21–27 cm) in half-size steps so all systems agree.
+
+### Check-digit rules (all verified against Wikipedia articles; algorithms are facts)
+
+| Code | Rule |
+|---|---|
+| EAN-13 / UPC-A / GTIN-8/12/13/14 | Weights 3,1,3,1… starting from the rightmost data digit (the one next to the check digit); check = (10 − sum mod 10) mod 10. UPC-A = EAN-13 with a leading 0 (GS1 prefix of a 12-digit GTIN is `0` + first two digits). GTIN-14 first digit is an indicator 1–8 (packaging level) or 9 (variable measure); 0 is not valid there. |
+| UPC-A number system (first digit) | 0,1,6,7,8,9 regular; 2 variable-weight; 3 drugs (NDC); 4 in-store/local; 5 coupons. |
+| ISBN-10 | Σ(weights 10..2 × first 9 digits) + check ≡ 0 mod 11; check = (11 − sum mod 11) mod 11, 10 → `X`. |
+| ISBN-13 | EAN-13 with prefix 978 or 979. 979 groups in use: 979-8 USA, 979-10 France, 979-11 Korea, 979-12 Italy. 978 groups 0 and 1 = English-language. For an en_US generator: `978-0…`, `978-1…`, `979-8…`. The official range file (`https://www.isbn-international.org/export_rangemessage.xml`) is XML only and the site says "You must not republish material from our site … without our written permission" — do not embed it; group/registrant length only matters for hyphenation, not validity. |
+| ISSN | Format `NNNN-NNNC`; weights 8..2 over first 7 digits, sum mod 11; check = 0 if remainder 0 else 11 − remainder; 10 → `X`. EAN-13 form: `977` + 7 ISSN digits (no check) + 2 variant digits + EAN check. |
+| IMEI | 15 digits: TAC 8 (RBI 2 + 6) + serial 6 + Luhn check (ISO/IEC 7812; from the right, double every second digit, sum digits, total ≡ 0 mod 10). SVN never enters the check. IMEISV = 14 digits + 2-digit SVN, no check. RBI `00` = test IMEI (Wikipedia [Reporting Body Identifier](https://en.wikipedia.org/wiki/Reporting_Body_Identifier)); live RBIs: 01 CTIA/PTCRB (US), 35 TÜV SÜD/BABT (UK), 86 TAF (China), 99 GHA. For fake data use TAC `00xxxxxx` so it can never match a real handset — UNVERIFIED: third-party pages claim the GSMA TS.06 test-TAC shape is `00 44` + 4 digits; the TS.06 PDF could not be text-extracted here. |
+| ASIN | 10 chars `[A-Z0-9]{10}`; non-books start `B0` + 8 alphanumerics (`^B0[A-Z0-9]{8}$`); books reuse their ISBN-10 verbatim. No check digit (Wikipedia). |
+| SKU | Not standardised (Wikipedia). Convention only: 8–12 uppercase alphanumerics, e.g. `[A-Z]{3}-\d{4}-[A-Z]{2}`; avoid leading 0 and O/I if you want scanner-safe. |
+
+### GS1 prefixes
+
+- Official table: [gs1.org/standards/id-keys/company-prefix](https://www.gs1.org/standards/id-keys/company-prefix) (rendered via Playwright; WebFetch gets 403). Copyright notice ([gs1.org/terms-use](https://www.gs1.org/terms-use)): reproduction allowed only "in unaltered form … for your personal, non-commercial use or use within your organisation"; "You are not permitted to re-transmit, distribute or commercialise the information or material without seeking prior written approval from GS1." → Do not copy the GS1 page. The prefix-to-country mapping is factual and also on Wikipedia ([List of GS1 country codes](https://en.wikipedia.org/wiki/List_of_GS1_country_codes), CC BY-SA 4.0 — avoid verbatim copy). Safe path: embed only the US/special ranges you need, written from the facts below.
+- Ranges relevant to an en_US generator (from the GS1 page): 001–019, 030–039, 060–139 GS1 US (UPC-A compatible); 020–029 restricted circulation within a region; 040–049 restricted within a company; 050–059 GS1 US reserved; 200–299 restricted circulation (region); 952 "used for demonstrations and examples of the GS1 system"; 977 ISSN; 978–979 ISBN; 980 refund receipts; 981–983 coupons (common currency); 990–999 coupons. Prefixes do not identify country of origin. Selected others: 300–379 France, 400–440 Germany, 450–459 & 490–499 Japan, 500–509 UK, 690–699 China, 730–739 Sweden, 750 Mexico, 754–755 Canada, 760–769 Switzerland, 800–839 Italy, 840–849 Spain, 870–879 Netherlands, 880–881 South Korea, 890 India, 930–939 Australia, 940–949 New Zealand.
+- Generator rule: for fake UPC/EAN use prefix `952` (GS1 demo) or a `2xx` restricted-circulation prefix — never a real company prefix; for US-looking UPC-A use number system 0–1/6–8 with a random 5-digit manufacturer code and accept that it may collide with real products.

+- Licence: each RDF record carries `<cc:Work><cc:license rdf:resource="https://creativecommons.org/publicdomain/zero/1.0/"/>` → catalog metadata is CC0 1.0 (verified on `cache/epub/1/pg1.rdf`). The CSV itself has no header notice; treat as CC0 by the same source. Terms of use: do not hammer their servers (bulk feeds are the sanctioned path), "Project Gutenberg" is a trademark — royalties for commercial use of the *name*; do not brand the data file with it beyond a source citation.
+- Embed: yes (CC0). For a fake-data library ship a filtered subset (Type=Text, Language=en, title + first author, maybe 5–10k rows) rather than 20 MB.

+# Open data sources for real Swedish geographic and postal-address data
+
+Researched 2026-09-16. Goal: Sweden → län → kommun → tätort/postort → street, with real postal codes, embeddable in an MIT-licensed library.
+
+## TL;DR
+
+| Need | Best source | Licence | Embed in MIT repo? |
+|---|---|---|---|
+| Län + kommun names/codes | SCB `kommunlankod-2026.xlsx` | CC0 1.0 | Yes, no attribution needed |
+| Population per kommun (weighting) | SCB PxWeb API `BE0101A/BefolkningNy` | CC0 1.0 | Yes |
+| Tätorter (2,017) with code, kommun, län, population | SCB open geodata WFS/GeoPackage `stat:Tatorter_2023` + PxWeb `MI0810A/LandarealTatortN` | CC0 1.0 | Yes |
+| Streets + house numbers + postnummer + postort + kommun + coordinates (~3.9M points) | Lantmäteriet *Belägenhetsadress Nedladdning, vektor* (STAC, GeoPackage per kommun) | CC BY 4.0 **plus** personal-data terms, purpose review, Basic-auth download | **Not as-is** — raw redistribution is bound by the personal-data terms; a derived aggregate (street ↔ postnummer ↔ postort, no house numbers) is the realistic path but needs a stated purpose approved by Lantmäteriet. Legal review needed. |
+| postnummer → postort (list only) | GeoNames `SE.zip` (18,887 rows, 1,780 postorter) | CC BY 4.0 | Yes with attribution — but source is an undated third-party file, likely stale |
+| Street names per kommun/postort without Lantmäteriet | Trafikverket NVDB *Gatunamn* (Lastkajen) | CC0 1.0 | Yes, but no postnummer; needs account to download |
+| Street names | OpenStreetMap | ODbL 1.0 | Effectively no (share-alike on the extracted database) |
+| Municipal address files | OpenAddresses `sources/se/*` (16 kommuner) | Mixed: CC0 (Göteborg, Malmö), CC BY 4.0 (Helsingborg), unspecified (Stockholm 2016 dump, Uppsala) | Per source |
+| Postal code register (authoritative) | PostNord → Postnummerservice Norden AB / Geposit AB | Commercial; "resale/sublicensing not permitted" | No |
+
+## 1. Lantmäteriet
+
+Since 2025-02-03 the EU High Value Datasets (HVD) products are fee-free but Lantmäteriet explicitly says they are *not* "öppna data" because conditions attach ([Avgiftsfria produkter](https://www.lantmateriet.se/sv/geodata/vara-produkter/avgiftsfria-produkter/)). Two tiers exist:
+
+- **Öppna data** — licence "Creative Commons, CC0" ([Öppna data](https://www.lantmateriet.se/sv/geodata/vara-produkter/avgiftsfria-produkter/oppna-data/)). Verified on Geotorget product pages for *Topografi 50/100/250/1M Nedladdning, vektor* ("Villkor: Creative Commons, CC0", "Juridisk prövning: Nej", GeoPackage, download in Geotorget or via the *Geotorget Nedladdning* API).

+Notes:
+- *Administrativ indelning* is not a standalone Geotorget product; it is the STAC collection `kommun-lan-rike`, the OGC API above, an [Inspire download](https://www.lantmateriet.se/sv/geodata/vara-produkter/produktlista/administrativ-indelning-nedladdning-inspire/) (Atom/WCS), or a layer in Topografi 100/250/1M (CC0). Topografi 1M also carries "tätortsgränser och tätortssymboler".
+- The STAC catalog root and collection/item listings are public (HTTP 200, no auth); it self-describes: "avgiftsfria och får användas enligt creative commons licens CC BY 4.0. För vissa informationsmängder kommer din användning att prövas juridiskt … och du behöver då godkänna särskilda användningsvillkor." Asset downloads on `dl1.lantmateriet.se` return **401 Basic** — credentials are the Geotorget account (private person) or a system account (organisation). Private accounts are "endast för privat bruk" ([konto-privatperson](https://geotorget.lantmateriet.se/konto-privatperson)); an MIT library is not private use, so apply as an organisation.
+- **Record count.** 290 STAC items (one per kommun), total 324 MB zipped. Smallest Bjurholm 143 KB, largest Stockholm 9.1 MB, Göteborg 8.9 MB, Malmö 4.9 MB. Fastighetsregistret held 3,882,361 valid addresses in 2022 (2,886,796 street addresses + 964,737 rural) per [SCB/LM presentation](https://kartografiska.se/wp-content/uploads/5C_Foretagsadresser_SCB_LM.pdf); the OSM import thread cites 3.7 M. So ~3.9 M address points, not 4–5 M.
+- **Fields** (JSON schema `belagenhetsadress-4.2.2.json`, matches *Nationell specifikation Adress* v1.0.1): `kommunkod`, `kommunnamn`, `kommundel` (geografisk kommundel), `adressomrade` + `adressomradestyp` (gatuadressområde / metertalsadressområde / byadressområde), `gardsadressomrade`, `adressplatsnummer`, `bokstavstillagg`, `lagestillagg`/`lagestillaggsnummer`, `adressplatstyp`, `adressplatsbeteckning`, `postnummer`, `postort` (both "beslutas av PostNord AB", only on current addresses), `popularnamn`, `distriktskod`/`distriktsnamn`, `adressattAnlaggning`, `anmarkningstyp`/`anmarkningstext`, `registerenhetsreferens` (property link), `objektidentitet`, `objektstatus`, `versionGiltigFran`, `geometri` (SWEREF 99 TM point). No län field — derive from kommunkod (first two digits).
+- Lantmäteriet treats addresses as personal data via Fastighetsregisterlagen § 6: usage only for the purpose approved in the application, EU/EEA-only storage, spot checks, revocation (terms PU §§ 3.3–4.2). The OSM community reports Lantmäteriet refused ODbL compatibility and OpenAddresses ([#7657](https://github.com/openaddresses/openaddresses/issues/7657), [#7608](https://github.com/openaddresses/openaddresses/issues/7608)) has not been able to include it; the OSM thread ([127427](https://community.openstreetmap.org/t/lantmateriet-belagenhetsadress/127427), 91 posts, last 2026-07-25) says one mapper got approval for a full 3.7 M import but no formal import has happened.
+- **Attribution text required (CC BY 4.0 + terms § 3.1):** product name as data source, "©Lantmäteriet", whether the data was processed, and that CC BY 4.0 applies — may be placed in accompanying documentation/metadata.
+- Ortnamn: name types include `Tätort` ("minst 200 invånare"), Bebyggelse, Trakt, Kyrka, Anläggning, nature names; Ortnamnsregistret holds ~980,000 names (Lantmäteriet, figure not re-verified). Not delivered as CSV.
+
+## 2. SCB (Statistics Sweden)
+
+- **Licence.** Statistics and geodata published as open data: "Creative Commons 0 1.0 Universal, CC0" ([användningsvillkor](https://www.scb.se/om-scb/om-scb.se-och-anvandningsvillkor)); since 2021-07-01. Optional credit "Källa: SCB" / "Source: Statistics Sweden"; do not cite SCB as source for data you have processed. API limit 10 requests / 10 s per IP.
+- **Län and kommuner with codes.** 21 län, 290 kommuner ([lan-och-kommuner](https://www.scb.se/hitta-statistik/regional-statistik-och-kartor/regionala-indelningar/lan-och-kommuner/)). Download: `https://www.scb.se/contentassets/7a89e48960f741e08918e489ea36354a/kommunlankod-2026.xlsx` (18 KB, HTTP 200). Codes: län 2 digits (01 Stockholm … 25 Norrbotten), kommun 4 digits = län + 2 (0180 Stockholm).
+- **Population per kommun.** PxWeb API `https://api.scb.se/OV0104/v1/doris/sv/ssd/START/BE/BE0101/BE0101A/BefolkningNy` — region dimension has 312 values (riket, 21 län, 290 kommuner), years 1968–2024 (verified 2026-09-16). Also `BE0101C/BefArealTathetKon` (density, 1991–2025).
+- **Tätorter.** 2,017 tätorter in 2023 (WFS `resultType=hits` on `stat:Tatorter_2023` → `numberOfFeatures="2017"`; SCB also states 2,017). Open geodata: `https://geodata.scb.se/geoserver/stat/wfs` (WFS/WMS) and GeoPackage download ([statistiska tätorter](https://www.scb.se/vara-tjanster/oppna-data/oppna-geodata/statistiska-tatorter/)). Attributes: `tatortskod`, `tatort`, `kommun`, `kommunnamn`, `lan`, `lannamn`, `area_ha`, `bef` (population), `ar`. Population per tätort also in PxWeb `MI0810/MI0810A/LandarealTatortN` (2,827 region codes, every 5 years to 2023). Also `Smaorter_2023`, `DeSO_2025`, `RegSO_2025`.
+
+## 3. Postal codes
+
+- **Owner.** PostNord Sverige owns and operates the postnummer system; PTS is supervisory authority; a Postnummerråd approves changes 3–4 times a year (sv.wikipedia). Register management is delegated to **Postnummerservice Norden AB**, machine access via **Geposit AB**. Postnummerservice's [terms](https://postnummerservice.se/en/information/kopvillkor): "free use within your own organization", "resale of data is not permitted", "sublicensing to third parties is not permitted" — unusable for an open library.
+- **No open list from PostNord, Lantmäteriet or Digg.** dataportal.se search for "postnummer" (2026-09-16) yields only Postnummerservice's own commercial catalogue entry ("Svenska postnummer och postorter", published 2012), Helsingborg's municipal postnummer polygons, and Lantmäteriet's Inspire address entry. The old dataportal community called the postnummer system "slarvats bort till ett privat bolag". GitHub CSVs (`zegl/sweden-zipcode`, `lapplandi/sveriges-postnummer`, `beshrkayali/sverige_postnummer`) state no licence or provenance — do not use.
+- **Lantmäteriet addresses carry `postnummer` + `postort`** on every current address point (set by PostNord), so the address product is the only lawful open-ish route to a *complete, current* postnummer ↔ postort ↔ street mapping.
+- **GeoNames `SE.zip`** ([readme](https://download.geonames.org/export/zip/readme.txt)): CC BY 4.0 ("a link on your website to www.geonames.org is ok"). Downloaded and counted: **18,887 rows, 18,887 distinct postnummer, 1,780 postorter, 22 admin1 values (21 län + blank), 285 admin2 (kommun code) values; 3,055 rows lack kommun; accuracy: 16,115 rows = 4 (centroid of postal code area), 389 = 1, 2,383 blank**. Fields: country, postal code (`111 64` with space), place name, admin1 name/code (län), admin2 name/code (kommun 4-digit), admin3, lat, lon, accuracy. The GeoNames sources page lists Sweden's source as `www.pellesoft.se/upload/program/prg00745.zip` with **no date** (URL now dead) — a hobbyist upload, so freshness is unknown; the row count (18.9 k) exceeds today's ~17 k total codes, indicating retired codes are still present. The zip is rebuilt daily (Last-Modified 2026-09-16) but that says nothing about the underlying data. 96 KB zipped.
+- **Counts.** Postnummerservice: "~17 000 postal codes", "10 500 deliverable postal codes", "1 743 postal cities"; Kartanalys: 10,839 geographic postnummer, 1,740 postorter; Wikipedia: >16,100 areas (2008). Changes quarterly.
+- **Structure** (sv/en Wikipedia): 5 digits written `NNN NN`. Lower numbers further south, except 1xx xx = Stockholm. First digit/tens: 10–19 Stockholm, 20–29 Skåne (Malmö 20–21), 30–39 southern Sweden, 40–49 Göteborg area (Göteborg 40–41), 50–59, 60–69, 70–79, 80–89, 90–99 progressively north to Norrbotten (98x). Postorter come in 2-, 3- or 5-position sizes; in two-position places the 3rd digit (in three-position the 4th) marks delivery type: 0 = boxes/postal, 1 = boxes/business, 2–4 and 6–7 = street delivery, 5 = rural (lantbrevbäring), 8 = reply mail, 9 = competitions/temporary — with exceptions in big cities. Box codes are therefore not street-deliverable and should be excluded when generating street addresses.
+
+## 4. Streets
+
+- **Lantmäteriet** — see § 1; `adressomrade` with `adressomradestyp = gatuadressområde` is the street name.
+- **Trafikverket NVDB** — CC0 1.0 Universal since 2017-04-03 ([trafikverket.se](https://www.trafikverket.se/e-tjanster/hamta-data-fran-trafikverket/) links `creativecommons.org/publicdomain/zero/1.0/deed.sv`; [OSM wiki](https://wiki.openstreetmap.org/wiki/Sweden/trafikverket)). Data product **Gatunamn** = "det officiellt adressbildande namnet på gatan" (municipal decision); Trafikverket is cleaning it in 2026 so it holds only names used in street addresses ([Vägnamn i NVDB](https://www.nvdb.se/sv/aktuellt/nyhetsarkiv/2026/vagnamn-i-nvdb/)). Download via Lastkajen (registration with e-mail + accept licence; Shapefile/GeoPackage), or the Datautbytesportal API. Gives street ↔ kommun (and geometry) but **no postnummer/postort**. Record count not published on the pages checked.
+- **OpenStreetMap** — ODbL 1.0. A list of street names extracted from OSM is a Derivative Database: "Where you make our data or any Derivative Database available to others, it must continue to be licensed under the ODbL" ([OSMF FAQ](https://osmfoundation.org/wiki/Licence/Licence_and_Legal_FAQ)); only *Produced Works* (maps etc.) escape share-alike. Embedding an OSM-derived JSON in an MIT repo therefore forces that data file to ODbL with attribution "© OpenStreetMap contributors" + link to openstreetmap.org/copyright, and downstream consumers inherit share-alike on the data. Not recommended.
+- **OpenAddresses** — 16 Swedish sources, all municipal (`sources/se/municipality_of_*.json`: Alingsås, Gislaved, Göteborg, Helsingborg, Höganäs, Kalmar, Kristinehamn, Malmö, Nacka, Sävsjö, Stockholm, Uppsala, Västerås, Vaxholm, Växjö, Österåker). OA does not relicense; licence is per source. Checked: Göteborg **CC0 1.0** (attribution "Göteborgs stad", shapefile, `gatunamn`), Malmö **CC0 1.0** (CSV with `ADRESSOMR`, `ADRESSPLAT`, `POSTNR`, `POSTORT`, cached 2024-11), Helsingborg **CC BY 4.0** ("Helsingborgs stad", GeoJSON with Gatunamn/Postnummer/Stad), Uppsala attribution required, licence name not stated (ArcGIS REST), Stockholm **no licence field**, data is a 2016 cache of a defunct WS. Usable for a few big cities only; no national coverage.
+- **Unique street-name counts.** SCB (Lägenhetsregistret 2019, [artikel](https://www.scb.se/hitta-statistik/artiklar/2021/pa-ringvagen-bor-det-flest/)): "Antalet gator eller vägar med en eller flera adresser är 399 175 i hela landet" — this is streets counted per place, not unique names. Most frequent: Ringvägen 205, Skogsvägen 204, Björkvägen 200, Skolgatan 196, Storgatan 180 (in 180 kommuner, 55,360 residents). A national unique-name count was not found; expect well under 399 k (probably 100–200 k) — **unverified**.
+
+## 5. Sizes
+
+| Level | Count | Source |
+|---|---|---|
+| Län | 21 | SCB |
+| Kommuner | 290 | SCB; 290 STAC items |
+| Tätorter (2023) | 2,017 | SCB WFS hits |
+| Postorter | ~1,740–1,780 | Postnummerservice 1,743; Kartanalys 1,740; GeoNames 1,780 |
+| Postnummer | ~17,000 total, ~10,500–10,840 deliverable/geographic | Postnummerservice, Kartanalys |

+| GeoNames SE.zip | 96 KB (18,887 rows) | download |
+| Ortnamn national GeoPackage | 58.5 MB zipped; ~980 k names | STAC; Lantmäteriet |
+
+Embedding suggestion (size-driven, before licence): län + kommun + population (~20 KB) and tätorter with population (~100 KB) are trivially embeddable under CC0. A postnummer→postort table is ~300 KB raw. A national (street, postort, postnummer-range) table at ~400 k rows is roughly 15–25 MB JSON, ~3–5 MB gzipped — optional download pack territory; a default pack could carry the top N streets per kommun (e.g. 20 × 290 ≈ 6 k rows, <300 KB).

+
+CC BY 4.0 and CC0 data files can sit in an MIT repo; the MIT licence covers the code, and a `DATA-LICENSES.md`/NOTICE lists each dataset with its licence and the attribution above. CC BY 4.0 § 2(a)(5)(B) (no technical protection measures) is irrelevant for a plain JSON file.
+
+## Could not verify
+- Whether the kommun-län-rike collection is CC0 or CC BY 4.0 (sources disagree).
+- Whether Lantmäteriet will approve an application whose purpose is publishing a derived open dataset; OSM/OpenAddresses experience suggests refusal is likely.
+- GeoNames Sweden source date; assume stale.
+- National count of unique street names; Gatunamn (NVDB) record count.
+- Exact number of active postnummer today (three sources: ~17 k total / 10.5–10.8 k deliverable).

ISO's own OBP is not open. |
+| **GeoNames** `admin1CodesASCII.txt`, `admin2Codes.txt` | CC BY 4.0 | admin1/admin2 names + geonameids per country | admin1 codes follow ISO 3166-2 for some countries and FIPS/numeric codes for others. |

Not a source of truth. |
+
+## 4. Postal codes — GeoNames and per-country openness
+
+- **GeoNames postal** (https://download.geonames.org/export/zip/, CC BY 4.0): TSV fields `country code, postal code, place name, admin name1, admin code1, admin name2, admin code2, admin name3, admin code3, latitude, longitude, accuracy (1–6)`. ~100 countries. Readme caveats: Canada and Netherlands partial codes only (full NL/CA files separate); UK from Royal Mail (© Royal Mail 2022 — attribution needed); Ireland/Malta first letters only; Argentina 5 chars; Brazil only `-000` codes; Chile/China partial. Lat/lon is algorithmic (matched to a GeoNames toponym or averaged from neighbours) — a locality centroid, not the postcode's. Per-country provenance is not documented, so DE's origin is unknown.
+
+| Country | Open? | Best open source |
+|---|---|---|
+| US | Yes (ZCTA, public domain); USPS list not a file | Census ZCTA + GeoNames US.txt |

+
+## 5. OpenAddresses and OpenStreetMap
+
+**OpenAddresses** (https://openaddresses.io/, https://batch.openaddresses.io/)
+- Global collection 48.39 GB (2026-09-07); US in 4 regional collections (table in section 1); Canada 1.25 GB. 3,282 sources (1,586 flagged "need attention"). Sources per country in the batch list: US 2,381, CA 222, FR 107, AU 58, FI 40, DE 32, NO 17, ES 6, DK 1, NL 1, GB 0.
+- Licensing: the repo LICENSE (BSD-3) covers source definitions only. **Each source keeps its own licence**, recorded in the source JSON and `state.txt`; "most sources only require attribution", but several are share-alike (ODbL, CC BY-SA) — e.g. OSM-derived and some municipal sources (https://geocode.earth/docs/reference/data_sources/). For MIT: filter by the per-source licence field, keep PD/CC0/CC BY/OGL/dl-de sources, generate the attribution file from `state.txt`. The old results.openaddresses.io coverage page is frozen at mid-2021.
+- The official registers above are themselves the OA sources for NO/DK/FI/NL/FR/ES/AU (and NAD/state sources for the US); going to the register directly gives cleaner licensing and fresher data. OA's value is one uniform CSV schema (`LON,LAT,NUMBER,STREET,UNIT,CITY,DISTRICT,REGION,POSTCODE,ID,HASH`).
+
+**OpenStreetMap** — ODbL 1.0
+- Any *substantial* extract (systematic, >100 features, or an area with >1,000 inhabitants) is a Derivative Database; distributing it — including embedded in a library — requires offering it under ODbL (share-alike) plus attribution. OSMF guideline: https://osmfoundation.org/wiki/Licence/Community_Guidelines/Substantial_-_Guideline ("village map OK, town map not OK"; repeated small extractions count as one).
+- Consequence: an embedded street/postcode list derived from OSM (OpenPLZ, Geofabrik postcode polygons, yetzt/postleitzahlen, OSM-derived dr5hn rows) cannot ship inside an MIT package without that data file being ODbL and tracked as a separate database; downstream users mixing it into their databases inherit share-alike. Keep OSM out of the default; at most an *optional* download pack clearly labelled ODbL.
+
+## 6. Embed vs. optional download — sizes and a recommendation
+
+**US (ships by default with en_US)**
+- Embed (small, public domain): 56 states (+ USPS abbreviations, FIPS), 3,234 counties (GEOID, name, state), ~19.5 k incorporated places with population + county + lat/lon (SUB-EST2025 joined to the Gazetteer), 33,791 ZCTAs with the ZCTA→place/county relationship, and a compact **street-name pool per place** derived from NAD (distinct `St_Name`+`St_PosTyp` per `Post_City`/`State`, top-N by frequency). Places+ZCTAs ≈ 2–4 MB gzipped; a street pool for all ~19.5 k places would run to tens of MB — cap to the ~1,000 largest places or ~20 streets per place for the default pack.
+- Download pack: full NAD (~80 M rows, multi-GB), TIGER `featnames`/`addrfeat` per county, OA US collections (~23 GB zipped). Real house numbers + ZIP+4 come only from here.
+- Deliverability caveat: NAD ZIP is optional, and place naming mixes `Post_City` (USPS city) with `Inc_Muni`; use `Post_City` + `Zip_Code` for mailing realism.
+
+**Other countries** — same shape: embed hierarchy + localities-with-population + postcode↔locality table (a few MB per country: NO's 2.6 M addresses collapse to ~4.5 k postcodes and ~90 k street names; DK 1,089 postcodes / 54 k street names; NL/FR/AU similar), with street pools for the largest localities; keep full address points as download packs fetched from the official Atom/CSV endpoints at runtime, never vendored (G-NAF ~5 GB, BAN CSV ~2 GB, BAG ~2 GB, NAR ~1 GB).
+
+**Licence file needed in the repo** (`DATA-LICENSES.md`): CC BY 4.0 (GeoNames, Kartverket, Klimadatastyrelsen, Statistics Finland, DVV/SYKE, NLS, ABS, CartoCiudad), NLOD 2.0 (Bring), OGL v3 (OS, ONS), Licence Ouverte 2.0 (BAN, La Poste, INSEE), G-NAF EULA notice, StatCan Open Licence notice, dl-de/by-2-0 and dl-de/zero-2-0 (BKG, Länder), Posti terms + download date, Catastro "© Dirección General del Catastro". CC0/public domain (US Census, DOT NAD, BAG, Wikidata) need nothing but are worth listing.
+
+## 7. Open questions / unverified
+- NAD ZIP fill rate and the list of non-participating states (DOT site blocks fetches; read the NAD coverage map manually).
+- Unique US street-name count — compute from NAD once downloaded.
+- Catastro licence text ("Descripción de la licencia" PDF) — confirm redistribution inside a software package.
+- INE aviso legal wording; whether callejero TRAMOS include código postal.
+- Destatis GV100 licence statement; Berlin/Bayern Hauskoordinaten status.
+- SYKE/Ryhti address API fields and bulk-download availability (avoindata.fi blocked the fetch).
+- NAR `MAIL_POSTAL_CODE` completeness per province.
+- GeoNames DE/US postal-code provenance and counts.
+- BAN CSV field list re-verification.

+## 2. Locale coverage and address data structure
+
+### Locale counts
+
+| Lib | Locales | Structure |
+|---|---|---|
+| JS | 77 dirs under `src/locales` (incl. `base`, `en_BORK`, `en_AU_ocker`) | One dir per locale, one file per module per key (`en/location/city_name.ts`). Fallback chain per Faker instance: `[de_CH, de, en, base]`; first locale that defines a key wins. `base` holds locale-independent data (ISO codes, time zones). A key may be explicitly `null` to mean "not applicable" (e.g. no zip codes for HK) so it does not fall through to `en`. https://fakerjs.dev/guide/localization.html |
+| PY | 126 locale codes listed; per provider: address 67, person 86, ssn 56 | Python subclasses per `providers/<provider>/<locale>/__init__.py` overriding tuples/formats of the base. Missing provider for a locale falls back to `en_US`. Coverage is uneven (`am_ET` = phone only). Multi-locale `Faker(['it_IT','en_US'])` with optional weights. https://faker.readthedocs.io/en/master/locales.html |
+| GO | 1 (English/US). No locale API; `Language`/`LanguageBCP` only emit language codes | Static Go maps in `data/*.go`. Open issue #352 "generate data for specific country/language" unanswered. https://github.com/brianvoe/gofakeit/issues/352 |
+| DF | 127 yml files in `src/main/resources` (incl. 49 country-only files like `_SE.yml` and 78 language(-region) files); README says "60+" | One YAML per locale (`sv-SE.yml`) under `sv-SE: faker: address: …`; `en/` split into 264 per-provider files. Locale chain `de_CH → de → en`, key-by-key. Values are templates `#{Name.first_name}`. Custom yml via `faker.addPath(locale, path)`. Country file (`_SE.yml`) layered over language file. |
+| BG | 50 (`data/*.locale.json`; README says 46) | Verbatim copy of faker.js (v5-era) locale JSON, merged with `data_extend/*.locale.json` by a gulp task, shipped as BSON. Falls back to `en`. https://github.com/bchavez/Bogus/wiki/Creating-Locales |
+| MM | 47 (53 dirs incl. `global`, `int`, `bin`, template) | Per locale six JSON files: `address, datetime, finance, food, person, text`. Everything else (internet, payment, code, hardware…) is locale-independent. |
+| CH | 1 (en; `postal` CA and `postcode` GB formats exist, `locale()` only returns codes) | Data inline in `chance.js`. |
+| RB | 58 yml files ("over 40" in README) | One YAML per locale `lib/locales/<code>.yml` (`en` split into `en/*.yml`), I18n gem, key-level fallback to `en`. |
+
+### Address data: real or synthetic, and correlation
+
+| Lib | Cities | Street names | Postcodes | Hierarchy / correlation |
+|---|---|---|---|---|
+| JS | `en`: real list `city_name` (~1000 US cities) is one of 5 `city_pattern`s; the other 4 are `{prefix} {firstName}{suffix}` style synthetic. `de`: 327 real cities; `sv`: no `city_name`, pattern-only synthetic. Varies per locale. | `en`: `street_pattern` = `{firstName} {street_suffix}` / `{lastName} …` (synthetic); `de`: 1800 real street names (from one NRW region). | Format masks (`#####`, `#####-####`). `en_US` has `postcode_by_state` so `zipCode({state:'CA'})` gives a state-prefixed range. | None between city↔state↔zip. `county` is a flat list. `timeZone` is per-locale. `nearbyGPSCoordinate` is the only "correlated" geo function. Issue #983: en_CA returned US cities; PR #2141 added real cities for ZA locales — real-city coverage is locale-by-locale volunteer work. |
+| PY | Per locale. `en_US`/`en_GB`: synthetic (`{city_prefix} {first_name}{city_suffix}`). `de_DE` 400+ real, `sv_SE` 45 real, `pl_PL` real, `ja_JP` real prefectures/cities/towns, `es_ES` real provinces + regions. | `en_US`: `{first_name} {street_suffix}`; `sv_SE`: prefix+suffix ("Björkgatan"); `de_DE`: synthetic name+Straße; `pl_PL`: real street-name pools. | Masks. `en_US`: `postcode_in_state` with real per-state numeric ranges (still random within range, "not correlated with cities"). `fr_FR`: postcode built from a real department number (correlated to department, not to city). `en_GB`: real outward-area letters but random assembly. `sv_SE`: `%####`. | No country→state→city hierarchy anywhere; `ja_JP` has prefecture–city pairs in data but methods pick independently. `geo.local_latlng(country)` returns real geonames places (name, lat, lon, country, tz) — the only real, correlated location record in the library. `address_formats` are weighted (`25.0` standard vs `1.0` military). |
+| GO | Real list of major US cities | Real-looking suffix lists; StreetName is a pool | `#####` mask | None: `Address()` picks city, state, zip independently; lat/lon are uniform random on the globe, not near the city. Open issue #196 "Better address" unanswered. |
+| DF | `en`: `city` formats are all synthetic (`#{city_prefix} #{Name.first_name}#{city_suffix}`); `cityName` draws from a separate real list. `sv-SE`: real `city_name` list; `de`: synthetic. | `en`: `#{Name.first_name} #{street_suffix}`; `de`: real `street_root` list combined randomly. | Masks; `en-US` `postcode_by_state` (`350##`), `zipCodeByState`, `countyByZipCode` (en-US only), `eircode` (IE). | None by default. Issue #1551 (Locale.CHINA yields "福建省南京市") open as "proposal". Issue #1477 unresolved directive for city names in some locales. |
+| BG | Whatever faker.js v5 had per locale (`en`: synthetic patterns only — real `city_name` list postdates the copy) | synthetic | Masks; `en_US` `postcode_by_state` | None. Issue #481 "Invalid Zip Codes (US)" open. Issue #342 "City returns people's names" (side effect of `{firstName}` patterns). |
+| MM | Real lists per locale (`en`: real US cities; `sv`: real municipalities incl. small towns) | `en`: real San Francisco street names; `sv`: real Swedish street names | `postal_code_fmt` mask per locale; `sv` has none | `state` (name+ISO 3166-2 abbr) real, but no link to city or postcode; `default_country` tied to locale. Open question #1584 on choosing default city per locale. |
+| CH | Synthetic (3-syllable word) | Synthetic word + real suffix | Real-format masks | None |
+| RB | `en`: synthetic patterns (`city_with_state` exists but is `city, state` random) ; some locales have real lists | `{first_name} {street_suffix}` | `#####`; `zip_code(state_abbreviation:)` uses per-state pattern (`900##`); doc says "may not be an actual state zip" | `full_address_as_hash` returns fields but does not correlate them. Issue #2881 (state vs state_abbr mismatch, country vs country_code mismatch) open; #1958 asked for geocodable city+zip; #2899 fake zips closed "not planned". |
+
+**Which libraries correlate any address fields at all:** Python Faker (`fr_FR` postcode↔department, `en_US` zip↔state range, `geo.local_latlng` real records), faker-js/Datafaker/Bogus/Ruby (`zip↔state` range only, en_US), Mimesis (locale↔country only). None ships a country→region→city→postcode hierarchy or city↔lat/lon.
+
+### Other localized fields (what varies per locale)
+
+- JS: `sv` overrides color, commerce, company, date, internet, location, person, phone_number, team; `en` defines 24 modules; `base` 9. So finance/vehicle/animal/food/science are effectively English-only.
+- PY: per-locale providers exist for address, automotive (plate formats), bank (IBAN/BBAN/SWIFT by country), company (VAT IDs), currency, date_time (month/day names), internet (TLDs, free email domains, user-name formats), job, lorem (word lists), person, phone_number, ssn (national IDs with check digits), passport, color, barcode (EAN prefixes), misc.
+- DF `de.yml` overrides: address, company, compass, creature, lorem, hipster, name, color, commerce, book, university, chuck_norris, space, music, games, food, simpsons, dr_who, vehicle. Country files (`_SE.yml`) mainly phone_number and address formats.
+- MM: only address, datetime, finance, food, person, text are localized.
+
+### Name weighting
+
+| Lib | Weighted by frequency? |
+|---|---|
+| PY | Yes, default `use_weighting=True`. `en_US`: ~500 female + ~500 male first names weighted from SSA decade tables, ~1000 surnames weighted by US Census; `sv_SE`: ~1000/1000/1000 weighted from Skatteverket/ISOF. Plus weighted `address_formats`, `random_element(OrderedDict)`. |
+| JS | No. Plain lists (`en`: ~650 female, ~550 male, ~400 generic first names). `helpers.weightedArrayElement` exists for user data only. |
+| GO | No. ~1500 first, ~500 last, plain slices. `Weighted(options, weights)` for user data. |
+| DF | No. `en`: ~1200 male, ~4400 female first names, ~1000 last, unweighted. |
+| BG | No (faker.js data); `Randomizer.WeightedRandom` for user data. |
+| MM | No. `en`: ~4000 female, ~3000 male, ~2500 surnames, unweighted. |
+| CH | No; `weighted()` helper only. |
+| RB | No. |
+
+## 3. Common complaints (issues and posts)
+
+- **Uncorrelated address parts** — the single most repeated request across every library:
+  - faker-ruby #1958 "Need an address object that has a street, city, zip that correlate" (geocoding breaks) https://github.com/faker-ruby/faker/issues/1958; #2881 "Consistent addresses" (state ≠ state_abbr, country ≠ country_code) https://github.com/faker-ruby/faker/issues/2881; #2899 "Fake Zip Codes" closed not-planned https://github.com/faker-ruby/faker/issues/2899; #275 zips like 90099 https://github.com/stympy/faker/issues/275
+  - fzaninotto/Faker #625 "Faking Legitimate Addresses" https://github.com/fzaninotto/Faker/issues/625
+  - java-faker #378 "Italy, Lima" / "USA, Moscow" https://github.com/DiUS/java-faker/issues/378; Datafaker #1551 wrong province–city for China https://github.com/datafaker-net/datafaker/issues/1551
+  - gofakeit #196 "city may not be in the same state as the zip" https://github.com/brianvoe/gofakeit/issues/196
+  - Bogus #481 invalid US zips https://github.com/bchavez/Bogus/issues/481
+  - Python Faker #697 "city in country" https://github.com/joke2k/faker/issues/697; #1812 `states_postcode` fails for territories
+- **Synthetic city names** ("East Jarretmouth", "Nord Müller-stadt"): faker-js #2021 merged `city`/`cityName` and documented that only some patterns are real https://github.com/faker-js/faker/issues/2021; Bogus #342 `Address.City` returns people's names https://github.com/bchavez/Bogus/issues/342; faker-js PR #2141 / #2127 / #3792 adding "real" or "more realistic" cities per locale.
+- **Localized data falling through to English**: faker-js #983 en_CA cities were US cities https://github.com/faker-js/faker/issues/983; Datafaker #1477 unresolved directive for city names https://github.com/datafaker-net/datafaker/issues/1477; #1358 ru-MD city names; Python #2432 vi_VN outdated administrative units.
+- **Fields within one record don't match**: Python #1185 profile name vs username/email https://github.com/joke2k/faker/issues/1185; #1420 email consistent with name https://github.com/joke2k/faker/issues/1420 (both stale, no maintainer answer); gofakeit `Person()` picks gender and first name independently and email from a fresh name.
+- **No frequency weighting / flat distributions**: blood types come out uniform when O+ and A+ are >70% of population (https://www.statology.org/how-to-validate-enhance-faker-profile-data-generation/); Python's `use_weighting` is the only built-in answer and only some locales supply weights; #1815 weighting silently dropped after adding a provider https://github.com/joke2k/faker/issues/1815.
+- **Formats that produce impossible values**: Python #1849 US phone numbers that can't exist; #1868 fr_FR postcodes with <5 digits; faker-js #1159 unrealistic BIC; #3429 routing numbers fixed to use a real Federal Reserve lookup table; Ruby #1123 wrong pt-BR zip ranges.
+- **No locales at all** in gofakeit (#352, open) and Chance.
+- **"Column-by-column" generation, no relationships between columns/tables** as a general critique of Faker-style tools (https://securityboulevard.com/2026/04/best-synthetic-data-generation-tools-and-platforms-compared-for-2026/).
+- **Uniqueness**: faker-js removed `faker.unique` and tells users to roll their own (https://fakerjs.dev/guide/unique.html); Python `fake.unique` raises `UniquenessException` after retries.
+
+## 4. Notable and unusual features
+
+- **Datafaker** — expression language `#{Name.first_name}`, `#{regexify '[a-z]{4,10}'}`, `#{numerify '##'}`, `#{bothify}`, `#{letterify}`, `#{templatify}`, `#{examplify}`, `#{options.option 'A','B'}`, `#{csv …}`, `#{json …}`, method calls with args (`#{date.birthday 'yy DDD'}`); nested resolution (https://www.datafaker.net/documentation/expressions/). `Schema.of(field(...), compositeField(...))` with transformers to CSV, JSON, YAML, XML, TOML, SQL (batch inserts, Postgres/Oracle/Spark dialects, ARRAY/MULTISET/ROW), `@FakeForSchema` POJO population (https://www.datafaker.net/documentation/schemas/). `faker.collection(...).len(3,5)`, infinite `stream()`, `faker.unique()`, sequences, custom yml via `addPath`. 263 providers, the largest pop-culture catalogue (≈110 franchises/games).

+- **Python Faker** — `use_weighting` (frequency-weighted names/formats from census data); `OrderedDict` weighted `random_element`; `fake.unique`, `fake.optional`; multi-locale instance with weights; `geo.local_latlng` real geonames records; `misc` file/archive/CSV/JSON/image generators; `pystr_format`; pytest fixture; CLI; 24 community providers (healthcare, market data, observability, airtravel, education, security, pyspark …).
+- **Chance** — `weighted`, `normal` (Gaussian), `unique`, `n`, `mixin`, `set` (override data), `pick/pickone/pickset`; mobile IDs (android_id, apple_token, bb_pin, wp7/8 anid); geohash/altitude/depth.
+- **Ruby faker** — `full_address_as_hash`, `Faker::Config.locale`, `Faker::UniqueGenerator`, `Faker::Config.random`; `Types` generator for random Ruby types; company registration numbers for ~12 countries; deep pop-culture catalogue (~85 themed generators).

+## 1. Person names
+
+### SCB (historic, frozen)
+- SCB stopped producing name statistics from 2024 and refers to Skatteverket (Namnsök page, verified). Statistikdatabasen folder BE0001 now holds only "Äldre tabeller som inte längre uppdateras" (BE0001D newborns, BE0001G whole population).
+- Whole-population xlsx (verified, downloaded): https://www.scb.se/contentassets/9fe7dbb460994c72b835163dbc491ef9/namn-med-minst-tva-barare-31-december-2022.xlsx — 13.1 MB, last-modified 2024-11-21, reference date 2022-12-31, names with >= 2 bearers, names in UPPERCASE.
+
+| Sheet | Rows (incl. 4 header rows) | Columns |
+|---|---|---|
+| Efternamn | 411,802 | Efternamn, Antal bärare |
+| Förnamn kvinnor | 91,247 | Förnamn, Antal bärare |
+| Förnamn män | 79,128 | Förnamn, Antal bärare |
+| Tilltalsnamn kvinnor | 57,785 | Tilltalsnamn, Antal bärare, Medelålder (only where >= 10 bearers, else "-") |
+| Tilltalsnamn män | 49,404 | same |
+
+- Gender split: a name appearing in both kvinnor/män sheets gives P(female) = count_k / (count_k + count_m).
+- Middle names: "Förnamn" = every given name a person carries; "Tilltalsnamn" = the one used. Förnamn-minus-tilltalsnamn frequency approximates middle-name usage. Legal "mellannamn" (a second surname) is a different concept, no longer grantable under namnlagen 2016:1013 (not verified this session).
+- Junk rows to filter: single letters ("A"), initials ("A-C", "K C", "JR"), "A:SON".
+- Legacy PxWeb tables (folder BE0001G, verified via web UI): BE0001T06AR, BE0001TNamn10 (tilltalsnamn >= 10 bearers 1999–2020), BE0001T100, BE0001T08AR, BE0001T07AR, BE0001FNamn10 (förnamn >= 10 bearers), BE0001F100, BE0001T03Ar (efternamn top), BE0001ENamn10 (efternamn >= 10 bearers 1999–2020). PxWebApi v1 (`api.scb.se/OV0104/v1/doris/sv/ssd/START/BE/BE0001/BE0001G/...`) returns HTTP 400 and PxWebApi 2 (`/v2beta/api/v2/tables/BE0001T06AR`) returns "Non-existent table" — these tables are web-UI only now (verified). Use the xlsx.
+- Licence: SCB terms page (verified): "Statistik och geodata som SCB tillgängliggör som öppna data i statistikdatabasen och i vår geodataplattform har licensen Creative commons 0 1.0 Universal, CC0" and "Om du använder eller sprider statistik från scb.se ska dock som källa alltid SCB anges". The xlsx sits on scb.se, not in statistikdatabasen — flag; treat as CC0 + "Källa: SCB".

+### Skatteverket (current)
+- Namn på nyfödda (2021+), annual: DCAT https://skatteverket.entryscape.net/store/26/metadata/416; CSV `fbf_namn_nyfodda.csv` https://skatteverket.entryscape.net/store/26/resource/417; JSON API https://skatteverket.entryscape.net/rowstore/dataset/da2556d0-c717-45e8-a1d8-3320161d3a7d/json?_limit=100&_offset=0 (47,529 rows, verified). Columns: rangordning, kön (Kvinna/Man), fodelsear, uppdateringsdatum, namn, gruppering (Kommun/…), grupperingsvärde (e.g. ALE), antal. Names in Title case. No licence field in DCAT — flag.
+- Most common surnames (> 2,000 bearers, ~500 names), 2026 text file (verified, 517 lines, format `Andersson 211808`): https://www.skatteverket.se/download/18.70685bee19c85dd5dd03b59/1775049117448/Fria_efternamn_namn_antal_textfil_2026.txt (also two PDFs).

+- Skatteverket general open-data terms (verified): "Vår öppna data är fri att använda och kräver varken några avtal eller innebär några avgifter" under lag 2022:818; no CC licence named except on the test-number datasets (CC0).
+- Skatteverket publishes no whole-population first-name list as a file; its statistikportalen "Så många har ett visst namn" is an interactive search (page 404 on fetch; unverified).
+
+Recommendation: embed SCB 2022 xlsx-derived lists (top-N per sheet with counts) + Skatteverket 2026 surname counts for freshness.
+
+## 2. Identifiers
+
+### Personnummer (Folkbokföringslagen 1991:481 18 §, verified via lagen.nu)
+- 10 digits: YYMMDD + födelsenummer (3 digits) + kontrollsiffra. Födelsenummer odd = male, even = female. Separator "-" ; "+" once the person turns 100. 12-digit form YYYYMMDDNNNC (no separator).
+- Check digit: Luhn/mod 10 over the 9 digits YYMMDDNNN (weights 2,1,2,1,… from the left; sum digits of two-digit products; check = (10 − sum mod 10) mod 10).
+- Before 1990 the first two födelsenummer digits encoded county; now random (Wikipedia, unverified officially).
+
+### Samordningsnummer
+- Same layout; day + 60 (3rd → 63); individual number random 001–999, odd male / even female; same Luhn (Skatteverket rättslig vägledning, via search excerpt; page itself blocked). Now regulated by Lag (2022:1697) om samordningsnummer (18 a § FBL repealed) — flag.
+- Example from Skatteverket: man born 1970-10-03, no. 239 → 701063-2391.
+
+### Official test numbers (Skatteverket, CC0 1.0)
+- Testpersonnummer dataset: https://www.dataportal.se/sv/datasets/6_67959/testpersonnummer (DCAT: https://admin.dataportal.se/store/6/metadata/67959?recursive=dcat). "Testpersonnummer med sekelsiffror för åren 1890-2025. Nya testnummer för kommande år läggs ut i december varje år." Formats: Excel (one file), CSV (split into many period files), JSON API https://skatteverket.entryscape.net/rowstore/dataset/b4de7df7-63c0-4e7e-bb59-1f156a591763/json?_limit=100 — resultCount 43,895 (verified), one column `testpersonnummer`, 12 digits.
+- Observed pattern (verified on 1890s CSV file fully and API samples at offsets 0/10000/30000/43880): every day gets two numbers, födelsenummer 238 (female) and 239 (male), through 2026-12-31; 1890s use 980/981 (plus a few 982/983/936). All Luhn-valid. Skatteverket blocks these from ever being assigned.
+- Testsamordningsnummer: DCAT https://skatteverket.entryscape.net/store/9/metadata/153; years 1914–2025; CSV per year; sample file 2022 (1,498 rows): days 61–91, individual numbers 238/239, Luhn-valid.
+- Should a generator restrict to these? Skatteverket does not mandate it, but only these are guaranteed never to collide with a real person; any other Luhn-valid number may be real. Recommended: default to the official series (date + 238/239, or 980/981 for 1890s) and embed nothing but the rule (~530 kB if the full list were embedded). Flag: the 238/239 rule was sampled, not exhaustively verified for every year.
+- Common practice elsewhere (Faker etc.): random date + random 3 digits + Luhn — valid but collision-prone.
+
+### Organisationsnummer
+- 10 digits NNNNNN-NNNN, last = Luhn over first 9 (same algorithm as personnummer). Digits 3–4 ("month") are always >= 20, distinguishing from personnummer (Wikipedia; not found on an official page — flag).
+- First digit (gruppnummer), Bolagsverket page (verified): 5 = aktiebolag, filialer, banker, försäkringsbolag, europabolag; 9 = handelsbolag, kommanditbolag; 7 or 8 = bostadsrättsföreningar, ekonomiska föreningar, näringsdrivande ideella föreningar etc.; 2 or 8 = trossamfund; 20… = state agencies (Bolagsverket itself 202100-5489); 3 = foreign companies. Wikipedia adds: 1 = dödsbon, 2 = stat/region/kommun, 6 = samfällighetsföreningar, 8 = ideella föreningar/stiftelser. Enskild firma = owner's personnummer.
+- VAT number (Skatteverket, verified): "SE" + 12 digits = organisationsnummer (10) + "01" ("De två sista siffrorna är alltid 01"). Written SE556047352101.
+
+### Bankgiro / Plusgiro (Bankgirot "10-modul" PDF 2016-12-01, verified)
+- Bankgironummer: 7 or 8 digits, last digit mod-10 (Luhn) check; printed 991-2346 (7) / 5555-5551 (8), i.e. hyphen before the last four digits. 90-konton (charity) 900-000x…904-999x, always 7 digits (Wikipedia).
+- Plusgironummer: 2–8 digits, last digit Luhn (Wikipedia/samlogic; not from an official Nordea page — flag). Printed with hyphen before check digit, e.g. "12 34 56-7" (convention, unverified).
+
+### Clearing numbers / bank accounts

+## Corrections to the brief's assumptions
+
+- Bowserinator/Periodic-Table-JSON is CC BY-SA 3.0 (not MIT) and has 119 rows; use PubChem CSV (118, PD).
+- wordfreq code is Apache-2.0 and its data CC BY-SA 4.0 — avoid the data.
+- CSS Color 4 has 148 named colours (rebeccapurple included).
+- Gutenberg #27889 Bartlett is the 9th edition (1903); the 1919 10th is not on Gutenberg (UNVERIFIED elsewhere).
+- CLDR file path is `cldr-dates-full/main/<locale>/ca-gregorian.json`; current package 48.2.0.
+- Diners Club US/Canada is a Mastercard co-brand on 55; replace the loose "Maestro 50/56–58/6xxx" rule with the explicit IINs in part 2.
+- Maestro/Discover/Diners/JCB/UnionPay lengths vary 12–19 — generate per the table, not a fixed 16.
+- The 987-65-4320..4329 SSN advertising range is repeated by third parties but not found on any ssa.gov/POMS page (UNVERIFIED).
+- DUNS dropped its mod-10 check digit in 2006 — no validation rule today.
+- IEEE's OUI "does not assert copyright" statement is only recorded second-hand (Debian/FSF); no current IEEE page restates it.
+- Sites blocking automation (403/Cloudflare): ssa.gov, www2.census.gov, swift.com, redcrossblood.org, loc.gov, gs1.org (WebFetch), standards-oui.ieee.org (needs browser UA). Download those manually with a browser UA.

+### Census 2010 surnames
+- Page: https://www.census.gov/topics/population/genealogy/data/2010_surnames.html
+- Files: full set https://www2.census.gov/topics/genealogy/2010surnames/names.zip (CSV + XLSX, `Names_2010Census.csv`), top 1000 `Names_2010Census_Top1000.xlsx`, docs https://www2.census.gov/topics/genealogy/2010surnames/surnames.pdf.
+- Fields (from surnames.pdf): `name, rank, count, prop100k, cum_prop100k, pctwhite, pctblack, pctapi, pctaian, pct2prace, pcthispanic`. `(S)` = suppressed percentage. Names are UPPERCASE.
+- Count: 162,253 surnames occurring ≥ 100 times (covers 90.1 % of people with a recorded surname); the CSV also has a trailing `ALL OTHER NAMES` row (UNVERIFIED — www2.census.gov returned 403 to curl this session; download with a browser).
+- Licence: US Census Bureau work → US federal government work, public domain in the US (17 U.S.C. §105). Census only asks for citation (https://www.census.gov/about/policies/citation.html: "U.S. Census Bureau, [Table], [Product], [Vintage], [URL], accessed on [date]"). Embeddable; cite source in the data file header.
+
+### Name prefixes / suffixes
+- No authoritative enumerated list exists. USPS Publication 28 §33 (https://pe.usps.com/text/pub28/28c3_011.htm) defines the fields: Name Prefix, First Name, Middle Name or Initial, Surname, **Suffix Title** = "maturity (e.g., JR, SR) and professional (e.g., PHD, DDS) suffixes"; example "MR. WALTER W. WITHERSPOON JR.".
+- Recommendation: hand-curate. Prefixes `Mr., Mrs., Ms., Mx., Dr., Rev.`; suffixes `Jr., Sr., II, III, IV, PhD, MD, DDS, Esq.`. Rule of thumb: generational suffix (Jr/Sr/II–IV) only with a male name in traditional US usage; never combine Jr. with Sr.; at most one generational suffix.
+
+### SSN
+- Structure: `AAA-GG-SSSS` (area 3, group 2, serial 4). No check digit (Wikipedia).
+- Randomization since **2011-06-25** (https://www.ssa.gov/employer/randomization.html): "Previously unassigned area numbers were introduced for assignment excluding area numbers 000, 666 and 900-999." Area no longer geographic.
+- Invalid per SSA POMS RM 10201.035 (https://secure.ssa.gov/apps10/poms.nsf/lnx/0110201035): area `000`, `666`, `900–999`; group `00`; serial `0000`.
+- Generator rule: area ∈ [001,899] \ {666}; group ∈ [01,99]; serial ∈ [0001,9999].
+- Advertising SSNs (https://www.ssa.gov/history/ssn/misused.html): `078-05-1120` (Woolworth wallet card, 1938; > 40,000 people claimed it) and `219-09-9999` (1940 Social Security Board pamphlet). Both are structurally valid — exclude from output.
+- `987-65-4320`–`987-65-4329` "reserved for advertising": repeated by searchbug.com, ssn-check.org, a Missouri state standard (https://oa.mo.gov/sites/default/files/CC-SocialSecurityNumberNamingStandardV050305.pdf, which even misprints it as 987-54-4329). **UNVERIFIED** — not found on any ssa.gov page or POMS this session; Wikipedia no longer carries it. Safe to use these ten as the library's "obviously fake" examples, but do not cite SSA for it.
+
+### ITIN (IRS)
+- IRS Publication 4757 (Rev. 6-2026), p. 5 (https://www.irs.gov/pub/irs-pdf/p4757.pdf): "All valid ITINs are nine-digit numbers in the same format as the SSN (9XX-8X-XXXX), beginning with a "9" and the 4th and 5th digits ranging from 50 to 65, 70 to 88, 90 to 92, and 94 to 99."
+- Group `93` = ATIN (adoption TIN); `89` reserved (Intuit/TaxSlayer support pages, not IRS — UNVERIFIED).
+- Generator rule: `9` + 2 digits + group ∈ {50–65, 70–88, 90–92, 94–99} + 4 digits (serial `0000` not documented as invalid for ITIN; avoid it anyway).
+
+### EIN (IRS)
+- Format `NN-NNNNNNN`. Page: https://www.irs.gov/businesses/small-businesses-self-employed/how-eins-are-assigned-and-valid-ein-prefixes ("The first two digits of your EIN show the IRS campus that assigned it or if you applied online").
+- Valid prefixes (union of the table, 2026-09-17):
+  `01 02 03 04 05 06 10 11 12 13 14 15 16 20 21 22 23 24 25 26 27 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 71 72 73 74 75 76 77 80 81 82 83 84 85 86 87 88 90 91 92 93 94 95 98 99`

+- Not valid: 00, 07, 08, 09, 17, 18, 19, 28, 29, 49, 69, 70, 78, 79, 89, 96, 97. No check digit.

+## 2. Finance
+
+### ABA routing number (RTN)
+- Wikipedia https://en.wikipedia.org/wiki/ABA_routing_transit_number: 9 digits; check: `(3(d1+d4+d7) + 7(d2+d5+d8) + (d3+d6+d9)) mod 10 = 0`.
+- First two digits: `00` US Government; `01–12` Federal Reserve districts (normal banks); `21–32` thrifts (historic, still valid); `61–72` non-bank payment processors/clearinghouses; `80` traveler's checks. Other prefixes unused (Wikipedia does not say so explicitly — inferred).
+- Generator rule: prefix ∈ {01–12, 21–32, 61–72}, 6 random digits, compute 9th as `(10 − (3d1+7d2+d3+3d4+7d5+d6+3d7+7d8) mod 10) mod 10`.
+- Open list of real RTNs: the Federal Reserve E-Payments Routing Directory (https://www.frbservices.org/resources/routing-number-directory/index.html) says "may not be sold, re-licensed, or otherwise used for commercial gain" → **not embeddable**. Generate synthetically.

+- CVV lengths: https://en.wikipedia.org/wiki/Card_security_code ("three-digit ... Visa, Mastercard, and Discover"; "American Express is a four-digit code on the front").
+- The requested "Maestro 50/56–58/6xxx" is a looser legacy rule; use Wikipedia's explicit IINs.
+- Wikipedia text is CC BY-SA 4.0 — copy the *facts* (not prose) into your table; facts are not copyrightable.

+- Reuse: neither page carries an open licence (Stripe docs are under Stripe's site terms). The numbers themselves are Luhn-valid facts, widely reproduced; embedding the numbers with a "from Stripe/PayPal test docs" note is low-risk but **UNVERIFIED** as an explicit grant. Alternative: generate Luhn-valid numbers from the IIN table above — no dependency on either vendor.
+
+### BIC / SWIFT (ISO 9362)
+- https://en.wikipedia.org/wiki/ISO_9362: 4 letters bank code + 2 letters ISO 3166-1 country + 2 alphanumeric location + optional 3 alphanumeric branch (8 or 11 chars; `XXX` = primary office). Location second char `0` = test BIC, `1` = passive participant, `2` = reverse billing.
+- Generator rule: `[A-Z]{4}[A-Z]{2}[A-Z2-9][A-NP-Z0-9]([A-Z0-9]{3})?` — avoid `0`/`1` as the 8th char for a "live" BIC.
+- SWIFT's BIC Directory is proprietary (SwiftRef licence, redistribution needs a separate "SwiftRef Redistribution License": https://www.swift.com/myswift/ordering/order-products-services/swiftref-redistribution-license) → **not embeddable**.
+- Open alternative: GLEIF BIC-to-LEI mapping, https://www.gleif.org/en/lei-data/lei-mapping/download-bic-to-lei-relationship-files, files at https://mapping.gleif.org/api/v2/bic-lei/ (monthly zip; `LEI-BIC-20260828.zip` → `lei-bic-20260828T000000.csv`, columns `LEI,BIC`, 39,347 rows). Licence: "BIC/LEI Mapping Table License Agreement" (https://www.gleif.org/lei-data/lei-mapping/download-bic-to-lei-relationship-files/2017-12-21_annex-2_bic-to-lei-mapping-table-license-agreement_final.pdf) — a CC0-style grant "for any purpose whatsoever, including ... commercial" but **conditional on reproducing the notice** "SWIFT © and database rights [month year]. All rights reserved. This Mapping Table has been developed by SWIFT. Any use of the Mapping Table ... is subject to the BIC/LEI Mapping Table License Agreement ... For the latest BIC information and updates, always refer to www.swift.com/bic." Embeddable in an MIT repo with that notice in the data file; it is a list of real live BICs (bank names not included — join to GLEIF LEI data if names are wanted).
+
+### ISIN (https://en.wikipedia.org/wiki/International_Securities_Identification_Number)
+- 12 chars: 2-letter country + 9 alphanumeric NSIN + 1 check digit.
+- Check: convert letters A=10…Z=35 (ASCII − 55) to produce a digit string, then Luhn over that string (double every second digit from the right, sum digits, check makes total ≡ 0 mod 10). Pitfall: work on the *expanded* digit string; a transposed letter pair can pass.
+
+### CUSIP (https://en.wikipedia.org/wiki/CUSIP)
+- 9 chars: 6 issuer + 2 issue + 1 check. Values: digits as-is, A=10…Z=35, `*`=36, `@`=37, `#`=38.
+- Check: for i in 1..8, v = value; if i even, v ×= 2; sum += v div 10 + v mod 10; check = (10 − sum mod 10) mod 10.
+- Real CUSIPs are proprietary (CGS/FactSet); generate synthetic ones only.
+
+### IBAN (ISO 13616)
+- Validation (https://en.wikipedia.org/wiki/International_Bank_Account_Number): move first 4 chars to end, letters → 10–35, integer mod 97 must equal 1; max 34 chars; check digits 02–98.
+- SWIFT registry: https://www.swift.com/standards/data-standards/iban-international-bank-account-number, PDF release 101 https://www.swift.com/sites/default/files/files/iban-registry-v101.pdf (release 100 was Oct 2025); TXT also published (URL **UNVERIFIED** — swift.com returns 403/errors to automation this session). Terms: free of charge; no explicit licence text found (**UNVERIFIED**). Country count: 89 countries per Wikipedia (Dec 2024).
+- Embeddable per-country length tables already extracted from the registry:
+  - php-iban `registry.txt` (https://github.com/globalcitizen/php-iban, **LGPL-3.0**): pipe-separated, 121 rows (116 official + unofficial), columns `country_code|country_name|domestic_example|bban_example|bban_format_swift|bban_format_regex|bban_length|iban_example|iban_format_swift|iban_format_regex|iban_length|bban_bankid_start_offset|...|country_sepa|swift_official|...|currency_iso4217|central_bank_url|central_bank_name|membership`. LGPL data in an MIT repo is awkward; use it as a *reference* to build your own table (formats are facts) rather than copying the file.
+  - ibankit-js (https://github.com/koblas/ibankit-js, **Apache-2.0**, registry v95) — same caveat.
+  - Best route: own table `{country, length, bban_format}` derived from the SWIFT PDF (facts), cite SWIFT.
+
+### Currencies (ISO 4217)
+- ISO says use is free: https://www.iso.org/iso-4217-currency-codes.html — "ISO allows free-of-charge use of its country, currency and language codes from ISO 3166, ISO 4217 and ISO 639". Official list from SIX: https://www.six-group.com/dam/download/financial-information/data-center/iso-currrency/lists/list-one.xml (+ `.xls`, `list-three` historic). Fields `CtryNm, CcyNm, Ccy, CcyNbr, CcyMnrUnts`; published 2026-01-01; 280 entity rows, 178 distinct codes. No symbols. No licence text inside the XML.
+- Alternatives:
+  - datasets/currency-codes (https://github.com/datasets/currency-codes): **PDDL** (public domain); `data/codes-all.csv` fields `Entity, Currency, AlphabeticCode, NumericCode, MinorUnit, WithdrawalDate`; built from SIX list one + three; no symbols. Embeddable.
+  - npm `currency-codes` v2.2.0 (https://github.com/freeall/currency-codes): **MIT**; fields `code, number, digits, currency, countries[]`; generated from the SIX XML; no symbols. Embeddable.
+  - umpirsky/currency-list (https://github.com/umpirsky/currency-list): **MIT**; code → localised name only (311 entries in `data/en_US/currency.json`, includes historic); no symbols, no numeric codes, no decimals.
+  - Debian iso-codes (https://salsa.debian.org/iso-codes-team/iso-codes): **LGPL-2.1+**; `data/iso_4217.json` has `alpha_3, name, numeric` only (179 entries); no symbols/minor units. LGPL → avoid embedding.
+  - Symbols: none of the above carry them. Unicode CLDR (`common/main/en.xml` currency symbols, Unicode License, MIT-compatible with notice) is the usual source — **UNVERIFIED this session**.
+
+### Crypto addresses
+- Bitcoin (https://en.bitcoin.it/wiki/List_of_address_prefixes): P2PKH version 0x00 → leading `1`; P2SH 0x05 → leading `3`; Base58Check 25–34 chars (alphabet excludes `0OIl`; last 4 bytes = first 4 of double-SHA256 of version+payload). Testnet `m`/`n`, `2`, `tb1`.
+- Bech32 (BIP-173, https://github.com/bitcoin/bips/blob/master/bip-0173.mediawiki, BSD-2-Clause): HRP `bc`, separator `1`, charset `qpzry9x8gf2tvdw0s3jn54khce6mua7l`, all-lowercase (or all-uppercase), max 90 chars; P2WPKH `bc1q…` = 42 chars, P2WSH `bc1q…` = 62 chars.
+- Bech32m (BIP-350, https://github.com/bitcoin/bips/blob/master/bip-0350.mediawiki): witness v1+ (P2TR `bc1p…`, 62 chars), checksum constant `0x2bc830a3` instead of 1.
+- Ethereum EIP-55 (https://eips.ethereum.org/EIPS/eip-55, CC0): `0x` + 40 hex; keccak256 of the lowercase hex (no 0x, as ASCII); for each hex letter, uppercase iff the corresponding hash nibble ≥ 8 (bit 4·i set). Digits unchanged.

+
+### DUNS
+- https://en.wikipedia.org/wiki/Data_Universal_Numbering_System: 9 digits, no significance; shown `NN-NNN-NNNN` or plain. Had a mod-10 check digit until ~Dec 2006; **dropped** since (expanded the pool by 800 M). So: any 9 digits are structurally valid today; no validation rule to enforce. Optional DUNS+4 suffix (4 alphanumerics) is user-assigned.

+- Columns: `ELF Code, Country of formation, Country Code (ISO 3166-1), Jurisdiction of formation, Country sub-division code (ISO 3166-2), Entity Legal Form name Local name, Language, Language Code (ISO 639-1), Entity Legal Form name Transliterated name, Abbreviations Local language, Abbreviations transliterated, Date created, ELF Status ACTV/INAC, Modification, Modification date, Reason`.
+- Counts: 4,002 rows; 130 countries; 3,790 ACTV / 212 INAC; 1,518 rows have a local abbreviation (e.g. US `N.A.`, `FSA`; SE `AB`… multiple abbreviations separated by `;`). US has 737 rows (per-state forms). Abbreviations are the field you want for `Inc`, `LLC`, `GmbH`, `AB`, `SAS`, `Pty Ltd`; many rows have none, so filter on non-empty abbreviation and status ACTV.

+
+### MIME extension mapping: jshttp/mime-db
+- https://github.com/jshttp/mime-db — **MIT** (GitHub API spdx MIT; npm `license: MIT`), version 1.54.0 on npm.
+- `db.json` (CDN: https://cdn.jsdelivr.net/npm/mime-db/db.json): object keyed by lower-case type → `{source, extensions[], compressible, charset}`.
+- Counts (1.54.0): **2,522 types**, **1,015 with extensions**; source = iana 2,136, apache 275, nginx 13, custom 98.
+- Sources: IANA registry (CC0), Apache httpd `mime.types` (Apache-2.0), nginx `mime.types` (BSD-2). **EMBED+ATTR** (keep the MIT copyright notice). Data updates are not semver-breaking per README.
+
+### IPv4 / IPv6 generation rules (RFCs, no data file needed)
+- RFC 5737 documentation: `192.0.2.0/24` (TEST-NET-1), `198.51.100.0/24` (TEST-NET-2), `203.0.113.0/24` (TEST-NET-3). https://www.rfc-editor.org/rfc/rfc5737.html
+- RFC 1918 private: `10.0.0.0/8`, `172.16.0.0/12`, `192.168.0.0/16`. Also useful: `100.64.0.0/10` CGNAT (RFC 6598), `198.18.0.0/15` benchmarking (RFC 2544), `169.254.0.0/16` link-local.
+- IPv6 documentation: `2001:db8::/32` (RFC 3849) and `3fff::/20` (RFC 9637, "expands on the existing 2001:db8::/32 … with the reservation of an additional, larger prefix"). ULA `fc00::/7` (use `fd00::/8`), link-local `fe80::/10`.
+- Validation: generate inside those blocks; avoid network/broadcast (`.0`/`.255`) if the consumer expects host addresses. Format IPv6 per RFC 5952 (lower-case hex, `::` once, longest zero run).
+
+### MAC OUI (IEEE MA-L)
+- CSV: https://standards-oui.ieee.org/oui/oui.csv (3.8 MB, **40,161 rows**, fields `Registry,Assignment,Organization Name,Organization Address`; Assignment is 6 hex chars). Server returns HTTP 418 to non-browser user agents; fetch with a browser UA. Also MA-M `oui28.csv`, MA-S `oui36.csv`, CID `cid.csv`.
+- Licence: no licence on the IEEE pages themselves (site footer "© IEEE – All rights reserved" is generic). Debian's `ieee-data` copyright file (https://metadata.ftp-master.debian.org/changelogs/main/i/ieee-data/unstable_copyright) records IEEE's 2014 statement: *"IEEE does not assert any copyright in the OUI Public Listing or attempt to restrict distribution of the listing in any way. The IEEE Registration Authority does, however, strongly encourage those who use the list to obtain it directly from IEEE…"* — same text in the FSF directory. Debian ships it in `main` on that basis. **EMBED+ATTR** (cite the statement); the org-address column is not needed — keep `Assignment,Organization Name` only (~1 MB → few hundred KB). UNVERIFIED: no current IEEE page restates it (regauth FAQ and IPR pages do not mention it).
+- Alternative needing no data: locally administered unicast MAC — first octet's bit 1 (U/L) = 1, bit 0 (I/G) = 0 → second hex digit ∈ {2, 6, A, E}, e.g. `x2:xx:xx:xx:xx:xx`. Guaranteed never to collide with a vendor OUI. Notations: `01:23:45:67:89:ab`, `01-23-45-67-89-AB`, Cisco `0123.4567.89ab`.

+- Embed: Yes — the unit *names/symbols* are facts (not copyrightable); attribute "SI Brochure, BIPM, CC BY 4.0" anyway.
+- Data (cross-checked against https://en.wikipedia.org/wiki/International_System_of_Units):
+  - 7 base units: second s (time), metre m (length), kilogram kg (mass), ampere A (electric current), kelvin K (thermodynamic temperature), mole mol (amount of substance), candela cd (luminous intensity).
+  - 22 coherent derived units with special names: radian rad, steradian sr, hertz Hz, newton N, pascal Pa, joule J, watt W, coulomb C, volt V, farad F, ohm Ω, siemens S, weber Wb, tesla T, henry H, degree Celsius °C, lumen lm, lux lx, becquerel Bq, gray Gy, sievert Sv, katal kat.

+- Format rules for valid output: unit symbols are case-sensitive (`s` vs `S`, `m` vs `M`); prefix and unit symbol are joined without a space (`kJ`, `µs`); a space separates number and unit (`12 kg`), except the degree/minute/second of plane angle; `kg` already carries a prefix — never `µkg`; micro is Greek mu U+03BC (U+00B5 micro sign is the legacy compatibility character); ohm is U+03A9 (U+2126 OHM SIGN is deprecated); `°C` not `° C`.

+  - Feasibility, live SPARQL (https://query.wikidata.org/sparql), pattern `?t wdt:P31 wd:Q16521; wdt:P105 wd:Q7432; wdt:P171* wd:<class>; wdt:P1843 ?cn FILTER(LANG(?cn)='en')` (taxon, rank species, parent-taxon chain, English common name):
+    - Mammalia Q7377: **5,759** species with ≥1 English common name.
+    - Aves Q5113: **12,432**.
+    - Reptilia Q10811: **16,369** — suspiciously large; Wikidata's parent chain likely pulls birds/Sauropsida in. Use Squamata Q122422 + Testudines Q223044 + Crocodilia Q1387 (or check the chain) instead.
+    - Insecta Q1390 and Plantae Q756: **timed out (502/504) every attempt** — trees too big for the 60 s public endpoint. Options: paginate by order (`P171` one level at a time), use the weekly JSON dump, or take GBIF instead.
+  - Sample rows (mammals): `Notoryctes typhlops` → "Central Desert Marsupial Mole", "Itjaritjari", "Marsupial Mole", "Southern marsupial mole", "Southern Marsupial Mole" — i.e. **several P1843 values per taxon, inconsistent casing, and indigenous-language names tagged `en`**. Validation: pick one name per taxon (prefer the one matching the item's English `rdfs:label`), normalise case, drop names that equal the scientific name.
+- **GBIF Backbone Taxonomy** https://www.gbif.org/dataset/d7dddbf4-2cf0-4f39-9b2a-bb099caae36c — licence **CC BY 4.0** (verified via https://api.gbif.org/v1/dataset/d7dddbf4-2cf0-4f39-9b2a-bb099caae36c, `license: http://creativecommons.org/licenses/by/4.0/legalcode`); required citation text: "GBIF Secretariat (2023). GBIF Backbone Taxonomy. Checklist dataset https://doi.org/10.15468/39omei". Embed: Yes with that citation. Vernacular names come via `/v1/species/{key}/vernacularNames`, each row from a *different* source checklist with its own licence (some CC BY-NC) — record and check per row. GBIF's site terms page (https://www.gbif.org/terms) was unreachable (timeout) — **UNVERIFIED** beyond the API field.
+- **faker-js** `src/locales/en/animal/*` (MIT; counts = quoted string lines on branch `next`): bird 821, snake 533, dog 493, cow 467, horse 342, rodent 161, insect 129, fish 95, cat 55, cetacean 52, rabbit 49, type 44 (generic: "bat, bear, bee, …, zebra"), pet_name 42, crocodilia 24, bear 8, lion 7. These are breeds/species mixed with common names, no class field; fine as MIT drop-ins. (A WebFetch summariser claimed 1,036 dogs; the regex count is 493 — treat the exact count as UNVERIFIED.)
+
+### Plants
+
+- Same Wikidata approach (CC0) — but the Plantae query timed out; paginate by order or family (`?t wdt:P171 ?family . ?family wdt:P105 wd:Q35409`) or use the dump.
+- GBIF Plantae (kingdomKey 6) vernacular names, CC BY 4.0, same per-row-licence caveat.
+- faker-js has **no** plant list (en locale dirs: airline, animal, app, book, color, commerce, company, database, date, finance, food, hacker, internet, location, lorem, medical, music, person, phone_number, science, team, vehicle, word).
+- USDA PLANTS database (public domain, has common names) — **UNVERIFIED**, not fetched.
+
+### Planets / moons
+
+- NASA NSSDCA Planetary Fact Sheet https://nssdc.gsfc.nasa.gov/planetary/factsheet/ — 10 columns (Mercury, Venus, Earth, Moon, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto) × 20 rows (mass 10^24 kg, diameter km, density, gravity, escape velocity, rotation period, day length, distance from Sun, perihelion, aphelion, orbital period, orbital velocity, inclination, eccentricity, obliquity, mean temp °C, surface pressure, number of moons, rings Y/N, magnetic field Y/N). HTML table only. NASA content "generally not subject to copyright in the United States" (https://www.nasa.gov/nasa-brand-center/images-and-media/); NASA asks to be acknowledged; the NASA insignia must not be used. Embed: Yes with "Source: NASA NSSDCA".
+- Wikidata (CC0): planets = `?p wdt:P31/wdt:P279* wd:Q634; wdt:P397 wd:Q525` → Mercury Q308, Venus Q313, Earth Q2, Mars Q111, Jupiter Q319, Saturn Q193, Uranus Q324, Neptune Q332 (plus hypothetical Theia Q1053432 — filter out). Moons = `?m wdt:P397 <planet>; wdt:P31/wdt:P279* wd:Q2537` (natural satellite; note **Q2199 is "dwarf planet"**, not moon): Saturn 165, Jupiter 85, Uranus 29, Neptune 16, Earth 5, Mars 2. Caveats: Wikidata lags IAU counts (Saturn has 274 recognised moons as of 2025 — UNVERIFIED figure); Earth's 5 includes quasi-satellites; provisional designations (`S/2004 S 3`) are labels too — filter `^S/\d{4}` if you want proper names only.
+
+### Blood type distribution
+
+- **US** (Stanford Blood Center https://stanfordbloodcenter.org/donate-blood/blood-donation-facts/blood-types/, verified; cites AABB Technical Manual 18th ed.): O+ 37.4 %, A+ 35.7 %, B+ 8.5 %, AB+ 3.4 %, O− 6.6 %, A− 6.3 %, B− 1.5 %, AB− 0.6 % (sums to 100.0). Facts — freely embeddable; cite Stanford/AABB.
+- American Red Cross https://www.redcrossblood.org/donate-blood/blood-types.html — **UNVERIFIED**: site returns HTTP 403 (Akamai) to both WebFetch and the headless browser. Search snippets say the Red Cross gives type O by ethnicity (Latino 57 %, African American 51 %, Caucasian 45 %) rather than an 8-way national table.
+- **Global**: no authoritative figure found. Wikipedia "Blood type distribution by country" gives a population-weighted row (O+ 38.4, A+ 27.3, B+ 8.1, AB+ 2.0, O− 13.1, A− 8.1, B− 2.0, AB− 0.01) that its own editors flag "unreliable source"; WorldAtlas gives O+ 42, A+ 31, B+ 15, AB+ 5, O− 3, A− 2.5, B− 1, AB− 0.5 with no source. Recommend shipping only the US table, or per-country tables from Wikipedia (facts; Wikipedia prose is CC BY-SA but the numbers are cited to national blood services — cite those).
+- Validation: ABO ∈ {A, B, AB, O}; Rh ∈ {+, −}; weights must sum to 100 ± rounding.

+- Either Bartlett text needs parsing (quote / author / source headings); no structured file. Wikiquote is CC BY-SA — avoid.
+- Validation: strip Gutenberg header/footer (`*** START OF THE PROJECT GUTENBERG EBOOK` … `*** END …`) before extraction; Gutenberg's trademark terms only bind if you keep the "Project Gutenberg" name on the output — strip it.

LICENSE: "Unless specified below, all files in the tz code and data (including this LICENSE file) are in the public domain" (only `date.c`, `newstrftime.3`, `strftime.c` are BSD-3). Embed: Yes, no notice needed.
+- `zone1970.tab` — **312** data rows; tab-separated; UTF-8; `#` comments. Columns: (1) comma-separated ISO 3166-1 alpha-2 codes of countries overlapping the zone, most-populous first; (2) coordinates in ISO 6709 `±DDMM±DDDMM` or `±DDMMSS±DDDMMSS` (lat then lon, no separator); (3) TZ name (`Europe/Zurich`); (4) comment, present iff the country has several zones. One row per timezone where civil time has agreed since 1970.
+- `zone.tab` — **418** rows, older one-country-per-row table (column 1 is a single country code); kept for backward compatibility. Prefer `zone1970.tab`.
+- `backward` — **252** `Link TARGET LINK-NAME` lines mapping old/merged names (`US/Eastern`, `Asia/Calcutta`, `Europe/Kiev`) to current ones; also a few `Zone` entries. Use it to (a) accept aliases as input and (b) never emit them as output.
+- UTC offsets: do **not** embed — offsets depend on DST rules that change several times a year. Derive at runtime: `new Intl.DateTimeFormat('en-US', { timeZone, timeZoneName: 'longOffset' }).formatToParts(date)` → part `timeZoneName` = `GMT-05:00` (or `GMT` for zero) — strip `GMT`, treat bare `GMT` as `+00:00`. Validation of a generated zone name: `Intl.supportedValuesOf('timeZone')` (canonical names only; whether links like `US/Eastern` appear depends on the ICU build) or `try { new Intl.DateTimeFormat(undefined, { timeZone }) } catch { invalid }`, which accepts links too.

+  - `months.{format|stand-alone}.{abbreviated|narrow|wide}` keyed `"1".."12"`; `days.{format|stand-alone}.{abbreviated|narrow|short|wide}` keyed `sun..sat`.
+  - `dateFormats`: en = full `EEEE, MMMM d, y`, long `MMMM d, y`, medium `MMM d, y`, short `M/d/yy`.
+  - `timeFormats`: en = full `h:mm:ss a zzzz`, long `h:mm:ss a z`, medium `h:mm:ss a`, short `h:mm a` — **the `a` is preceded by U+202F NARROW NO-BREAK SPACE**; `*-alt-ascii` variants use a plain space. Pick one spelling (ASCII) and ignore the other.
+  - `dateTimeFormats.{full|long|medium|short}` = glue like `{1}, {0}` ({1} date, {0} time); `availableFormats` = skeleton→pattern map (`yMMMd` → `MMM d, y`), plus `intervalFormats`, `appendItems`.
+  - `dayPeriods.format.abbreviated`: `am: AM`, `pm: PM`, plus `midnight`, `noon`, `morning1`… variants.
+- Pattern letters follow LDML (https://unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table): `y` year, `M`/`L` month (format/stand-alone), `d` day, `E`/`c` weekday, `h` 1–12, `H` 0–23, `a` AM/PM, `z`/`zzzz` zone name, `x`/`X` ISO offset; literal text in single quotes. Same patterns drive `Intl.DateTimeFormat` internally, so runtime `Intl` can replace embedding for month/weekday names if bundle size matters.

+- Flag emoji: derive, no data needed — for alpha-2 `XY`, emit U+1F1E6 + (X − 'A') and U+1F1E6 + (Y − 'A') (regional indicator symbols).
+- Recommendation: `datasets/country-codes` (PDDL) covers every requested field (name, alpha2, alpha3, numeric, calling code, TLD, capital, currency, languages) in one CSV; flag emoji derived. `annexare` (MIT) is the fallback for native names/calling codes if PDDL's ISO caveat worries you; it lacks TLD.
+- Validation rules: alpha-2 `^[A-Z]{2}$`, alpha-3 `^[A-Z]{3}$`, numeric `^\d{3}$` (zero-padded, keep as string); calling code 1–3 digits, NANP countries share `1`; TLD `^\.[a-z]{2}$` (ccTLD = lowercase alpha-2, exceptions: GB uses `.uk`).

+- Recommendation: `langs` or `iso-639-1` (MIT) for 639-1 names; both are small and derived from public code tables. Anything 639-3-sized is LGPL or SIL-restricted.
+- Rules: 639-1 `^[a-z]{2}$`, 639-2/3 `^[a-z]{3}$`; 639-2 has B/T pairs (e.g. `fre`/`fra`, `ger`/`deu`) — pick one consistently (T codes = 639-3).

+
+- Recommendation: for an en_US library, ship only the US list (Census/USPS, public domain: 50 states + DC, optionally territories) — ISO 3166-2 code = `US-` + USPS abbreviation. Skip the ~5000-row world list; every open compilation is LGPL, CC BY-SA or unclear.
+- Rule: `^[A-Z]{2}-[A-Z0-9]{1,3}$`.
+
+## 11. Commerce
+
+### Word lists (product name / adjective / material)
+
+- [@faker-js/faker](https://github.com/faker-js/faker) 10.6.0 — MIT (LICENSE covers code and locale data; copyright Faker contributors 2022-2025 and Marak Squires 2011-2020; acknowledges Ruby Faker and Perl Data::Faker, both MIT). No separate data licence.
+- Provenance policy in [CONTRIBUTING.md](https://github.com/faker-js/faker/blob/next/CONTRIBUTING.md): "Faker must not contain copyrighted materials"; facts (finite known lists) are OK; compilations must not be copied from a single source (Wikipedia, "most popular" articles, government sites) because "a compilation of facts can be copyrighted" — contributors are told to draw on multiple sources and their own judgement.
+- Verdict: reusing faker's `en` commerce lists (`product_name.adjective/material/product`, `department`) is fine under MIT — keep the MIT notice with the copied data. The lists are short curated words (no external dataset). Nothing in the repo or docs restricts locale-data reuse beyond MIT.
+
+### Garment and shoe sizes
+
+- Letter sizes XS–XXL: EN 13402-3 letter codes with chest/bust ranges (Wikipedia [EN 13402](https://en.wikipedia.org/wiki/EN_13402), CC BY-SA — but the table is a handful of facts; the standard itself is paywalled). Men chest / women bust cm: XXS 70–78 / 66–74, XS 78–86 / 74–82, S 86–94 / 82–90, M 94–102 / 90–98, L 102–110 / 98–107, XL 110–118 / 107–119, XXL 118–129 / 119–131, 3XL 129–141 / 131–143.
+- US numeric women's sizes (0–20, even) come from ASTM D5585 (paywalled); no open dataset. Just generate the even-number series.
+- Shoe sizes: no open dataset found (search hits are ML demos and retailer charts). Use the formulas from Wikipedia [Shoe size](https://en.wikipedia.org/wiki/Shoe_size) (facts, not copyrightable): EU (Paris point) ≈ 1.5 × foot cm + 2 (i.e. 3/20 × mm + 2); UK adult ≈ 3 × foot in − 23; US men ≈ 3 × foot in − 22 = UK + 1; US women (common) = US men + 1.5 (FIA scale: 3 × foot in − 21); Mondopoint = foot length mm. ISO/TS 19407:2023 has the official conversion tables (paywalled). Generate from a foot length (men 24–31 cm, women 21–27 cm) in half-size steps so all systems agree.
+
+### Check-digit rules (all verified against Wikipedia articles; algorithms are facts)
+
+| Code | Rule |
+|---|---|
+| EAN-13 / UPC-A / GTIN-8/12/13/14 | Weights 3,1,3,1… starting from the rightmost data digit (the one next to the check digit); check = (10 − sum mod 10) mod 10. UPC-A = EAN-13 with a leading 0 (GS1 prefix of a 12-digit GTIN is `0` + first two digits). GTIN-14 first digit is an indicator 1–8 (packaging level) or 9 (variable measure); 0 is not valid there. |
+| UPC-A number system (first digit) | 0,1,6,7,8,9 regular; 2 variable-weight; 3 drugs (NDC); 4 in-store/local; 5 coupons. |
+| ISBN-10 | Σ(weights 10..2 × first 9 digits) + check ≡ 0 mod 11; check = (11 − sum mod 11) mod 11, 10 → `X`. |
+| ISBN-13 | EAN-13 with prefix 978 or 979. 979 groups in use: 979-8 USA, 979-10 France, 979-11 Korea, 979-12 Italy. 978 groups 0 and 1 = English-language. For an en_US generator: `978-0…`, `978-1…`, `979-8…`. The official range file (`https://www.isbn-international.org/export_rangemessage.xml`) is XML only and the site says "You must not republish material from our site … without our written permission" — do not embed it; group/registrant length only matters for hyphenation, not validity. |
+| ISSN | Format `NNNN-NNNC`; weights 8..2 over first 7 digits, sum mod 11; check = 0 if remainder 0 else 11 − remainder; 10 → `X`. EAN-13 form: `977` + 7 ISSN digits (no check) + 2 variant digits + EAN check. |
+| IMEI | 15 digits: TAC 8 (RBI 2 + 6) + serial 6 + Luhn check (ISO/IEC 7812; from the right, double every second digit, sum digits, total ≡ 0 mod 10). SVN never enters the check. IMEISV = 14 digits + 2-digit SVN, no check. RBI `00` = test IMEI (Wikipedia [Reporting Body Identifier](https://en.wikipedia.org/wiki/Reporting_Body_Identifier)); live RBIs: 01 CTIA/PTCRB (US), 35 TÜV SÜD/BABT (UK), 86 TAF (China), 99 GHA. For fake data use TAC `00xxxxxx` so it can never match a real handset — UNVERIFIED: third-party pages claim the GSMA TS.06 test-TAC shape is `00 44` + 4 digits; the TS.06 PDF could not be text-extracted here. |
+| ASIN | 10 chars `[A-Z0-9]{10}`; non-books start `B0` + 8 alphanumerics (`^B0[A-Z0-9]{8}$`); books reuse their ISBN-10 verbatim. No check digit (Wikipedia). |
+| SKU | Not standardised (Wikipedia). Convention only: 8–12 uppercase alphanumerics, e.g. `[A-Z]{3}-\d{4}-[A-Z]{2}`; avoid leading 0 and O/I if you want scanner-safe. |
+
+### GS1 prefixes

+- Official table: [gs1.org/standards/id-keys/company-prefix](https://www.gs1.org/standards/id-keys/company-prefix) (rendered via Playwright; WebFetch gets 403). Copyright notice ([gs1.org/terms-use](https://www.gs1.org/terms-use)): reproduction allowed only "in unaltered form … for your personal, non-commercial use or use within your organisation"; "You are not permitted to re-transmit, distribute or commercialise the information or material without seeking prior written approval from GS1." → Do not copy the GS1 page. The prefix-to-country mapping is factual and also on Wikipedia ([List of GS1 country codes](https://en.wikipedia.org/wiki/List_of_GS1_country_codes), CC BY-SA 4.0 — avoid verbatim copy). Safe path: embed only the US/special ranges you need, written from the facts below.
+- Ranges relevant to an en_US generator (from the GS1 page): 001–019, 030–039, 060–139 GS1 US (UPC-A compatible); 020–029 restricted circulation within a region; 040–049 restricted within a company; 050–059 GS1 US reserved; 200–299 restricted circulation (region); 952 "used for demonstrations and examples of the GS1 system"; 977 ISSN; 978–979 ISBN; 980 refund receipts; 981–983 coupons (common currency); 990–999 coupons. Prefixes do not identify country of origin. Selected others: 300–379 France, 400–440 Germany, 450–459 & 490–499 Japan, 500–509 UK, 690–699 China, 730–739 Sweden, 750 Mexico, 754–755 Canada, 760–769 Switzerland, 800–839 Italy, 840–849 Spain, 870–879 Netherlands, 880–881 South Korea, 890 India, 930–939 Australia, 940–949 New Zealand.
+- Generator rule: for fake UPC/EAN use prefix `952` (GS1 demo) or a `2xx` restricted-circulation prefix — never a real company prefix; for US-looking UPC-A use number system 0–1/6–8 with a random 5-digit manufacturer code and accept that it may collide with real products.

+- Licence: each RDF record carries `<cc:Work><cc:license rdf:resource="https://creativecommons.org/publicdomain/zero/1.0/"/>` → catalog metadata is CC0 1.0 (verified on `cache/epub/1/pg1.rdf`). The CSV itself has no header notice; treat as CC0 by the same source. Terms of use: do not hammer their servers (bulk feeds are the sanctioned path), "Project Gutenberg" is a trademark — royalties for commercial use of the *name*; do not brand the data file with it beyond a source citation.
+- Embed: yes (CC0). For a fake-data library ship a filtered subset (Type=Text, Language=en, title + first author, maybe 5–10k rows) rather than 20 MB.

-# Release checklist
+# Plan
 
-## Before v0.1.0
+Ordered as the releases that ship it.
+
+## v0.1.0
+
+### Comprehension, until the panel scores 7.0
+
+Nothing else ships while the score is under 7.0 — no feature, no category, no data —
+bar a security fix and a dependency bump, per README goal 2. This section is one
+round, replayed: the `comprehension-panel` skill's nine-seat findings run at depth 1,
+a PR per item it names, then the run again, until the score passes. The run is the
+nine-seat one: the round is meant to buy architectural change, and the four-seat
+scoring run names too little to steer one. A fresh run replaces the items below.
+
+Scores, newest last: 5.9 on 2026-09-20 (Navigation 7.0, Locality 5.2, Shape 5.9,
+Self-sufficiency 5.7), eight of nine seats capped by Locality or Self-sufficiency, all
+nine naming `hold.go`, `draw.go` and `family.go` first for reading cost: 1,138 lines in
+which each file carries both a load-time fence and render-time machinery, so no file
+name says whether a unit runs at `New` or at `Fake`.
+
+This round, in order:
+
+- Define the fence vocabulary where a reader of the code meets it: fence, hold, pin,
+  draw, draw group, expansion against render, family, whole. It exists only across five
+  README sections today, and every reader paid for it before the three files read at all.
+- Say on the `template` struct which pass fills which field, and that `compileFormat`
+  runs a second time once `linkTemplateRefs` binds the references: nine of its fields
+  are written by four other files, and the order lives only in `loadData`'s body.
+- State on `rowSet` that it simulates `(*draws).pin` and `rowOf`, and prove the two
+  agree with a test: the load-time walk reimplements the render-time pinning, nothing
+  catches them drifting, and the failure is data that loads and then renders a family
+  that disagrees.
+- Put `draws` and its methods in one file: it is declared in `hold.go:262` and all
+  eight of its methods sit in `family.go`, so a jump to the type lands where none of
+  the behaviour is.
+- Split `hold.go`, `draw.go` and `family.go` so each file holds one phase, the
+  load-time fences apart from the render-time machinery, changing no logic.
+- Move `nodeScope`, `checkScope` and `checkRenders` out of `graph.go` and refresh the
+  README Layout lines for `graph.go` and `data.go`: the order every load fence runs in
+  is the load path's spine, and no file name carries it.
+- Name the `draw` stem apart: the free `pinned` in `hold.go` is not `(*draws).pinned`
+  in `family.go`, `compileFormat` is a method on both `*template` and `*table`, and
+  `draws`, `drawSet`, `drawScope`, `drawWalk`, `drawAt`, `drawKey`, `drawVisit` and
+  `drawRoute` no longer tell each other apart.

 ### Data
 
-Plan for the major data update. Research notes: `~/code/claude-handoffs/fejkdata/2026-09-16/`.
+Shape: T = table, t = template, c = choice. Read every factual list from a register
+by a `data-import/` script, as README goal 12 asks.
 
-#### Structure (proposal, pending review)
+- Add the remaining `misc` tables and templates, one row of the table below per chunk.
-
+- Read `misc.emoji` from the Unicode `emoji-test.txt` register, and `misc.car` from an
-`New` costs ~23 ms and 58k allocations for today's 200 KB, one allocation per
+  international make and model source; vPIC and Mobility Sweden are national, so they
-node, so real-world tables cannot ship as nested JSON objects. JSON says how a
+  build `en_US.car` and `sv_SE.car`.
-value is composed; TSV says which values exist.
+- Add the remaining locale categories: company, phone, finance, vehicle, words.
-
+- Give every shipped category building-block columns, `misc.uuid` → `variant` among
-- Add a table node: a category JSON naming a `rows` TSV beside it, whose header
+  them, and one record shape across the national ids; re-pin the shape.
-  names the columns and whose rows are the draw. Options `key` (the column a path
-  selects a row by), `name` (the column a path also selects by), `weight` (the
-  column that skews the draw), `parent` (the table a column links to). `{name}`
-  tokens read columns; a cell is a string node, so it may carry tokens. Index
-  rows on first draw; at load prove only the header, the options and any cell
-  token. A TSV nothing names is a load error.
-- In a data file, refuse a choice whose items are templates with one identical
-  field set, naming the TSV to write; an inline template is exempt, having no
-  file. A choice of strings stays a choice.
-- Convert `misc.timezone`, `car` and `useragent` to tables.
-- Let a path select a row by key or by name, `geo.SE.municipality[0180]` and
-  `geo.SE.municipality[Stockholm]`, and descend to a linked table by name,
-  `geo.SE.region[Skåne län].street`; a key or a linked table name may not equal
-  a column name (load error). A name that matches several rows outside a pinned
-  parent is an error listing the keys; inside one, `region[IL].locality[Springfield]`
-  resolves. Brackets need quoting in zsh; `:` would not.
-- Draw linked tables consistently within one render and draw group: the first
-  table drawn pins its ancestors, and a descendant is drawn inside them.
-- Keep country data under `geo/<alpha2>/`; a locale's `address` reads its
-  country's tree by reference, and a locale's `country` table carries the
-  localised names keyed by alpha2.
-- Ship full registers as packs, each a Go module with its own `embed.FS` and a
-  zip for `--data-path`; the default embed stays under ~1 MB per country and
-  `New` under ~50 ms.
-- Add `DATA-LICENSES.md` listing every dataset, its licence and its attribution,
-  and a `data-import/` directory of Python scripts that rebuild each TSV from its
-  source, so a refresh is one command per dataset.
-- Make every shipped category a record with its building blocks as columns
-  (`sv_SE.person` → `first`, `last`, `sex`, done in step 3; `misc.uuid` → `variant`).
-- Share the handle lists between `email.local` and `username` only if that is a
-  clean win — a reference between shipped categories is a major once tagged.
-
-#### Geo tree
-
-Five linked tables per country, generic names so a template ports across
-countries; the README maps each to the native term.
-
-| Table | SE | US | Weight |
-|---|---|---|---|
-| `region` | län (21) | state and DC (50; Hawaii has no incorporated place) | population |
-| `municipality` | kommun (290) | county with a shipped place | population |
-| `locality` | postort, tätort population | place of 25,000+ | population |
-| `postal-code` | postnummer with street delivery | ZCTA of a shipped place | one; address ranges |
-| `street` | gatunamn, top 10 per postort | street name, top 10 per place | segments; address ranges |
-
-- Shipped in step 2, README Data. `geo.SE.address` is a record over one consistent
-  draw. Each region row carries its timezone, each locality its centroid.
-- Let `geo.SE.locality[Lund].address` descend from a selected row into the
-  template beside the family: the path step must reach a sibling category and the
-  outer selector's pins seed every draw group of the render.
-- Ship the fuller sets, every US place of 10,000 and more streets per locality, as
-  packs; `--min-population` and `--streets-per-locality` on the scripts build them.
-- Fill the 398 Swedish localities weighted 200 from SCB småorter before v0.1.0.
 - Give the address records one column set across countries: `region` and
-  `municipality` as building-block columns on `geo.SE.address` too, in step 6.
+  `municipality` as columns on `geo.SE.address` too.
-- v0.1.0 ships SE and US; then NO, DK, FI, NL, FR, AU, CA, ES, GB, DE.
+- Fill the 398 Swedish localities weighted 200 from SCB småorter.
-- Revisit an application to Lantmäteriet for the exact street to postnummer
+- Give `url` and `email` a path that draws only domains nobody can register, keeping
-  pairing after v0.1.0; today a street goes to the nearest postal code centroid.
+  the wide set as the default, per goal 14: 17 of the 40 distinct ones shipped today
+  sit on `.se`, `.nu`, `.io` and `.co`, which anyone may register, and only RFC 2606's
+  `example.com`, `.net`, `.org`, `.test`, `.example`, `.invalid` and `.localhost`
+  provably reach nothing.
+- Audit the rest of the shipped set against goal 14 and give each a never-reaching
+  path where it lacks one: `phone` draws live PTS and NANP ranges, `bankgiro`,
+  `plusgiro` and `routing` draw live prefixes.
+- Stop `misc.territory[EH].tld` rendering `.eh`, the one shipped TLD `misc.tld` does
+  not hold: ISO 3166 reserves it for Western Sahara and the root zone has never been
+  delegated it, so no resolver answers for it and goal 3 promises otherwise.
+- Draw `en_US.phone`'s `exch` as a NANP central office code: `{int(100,999)}` renders
+  a leading 1 in about an eighth of draws, which libphonenumber rejects, and
+  `TestShippedUSPhone` proves the shape rather than the rule. Assert the rule with it.
+- Give a `sv_SE.personnummer` over 100 the `+` separator Skatteverket spells, or stop
+  drawing birthdates that reach 100: the format hard-codes `-`, and the 1930 floor
+  makes the oldest draws invalid from 2031.
+- Settle `en_US.ip` and `sv_SE.ip`, today byte-identical: either one `misc.ip` as the
+  decision "`misc` is what every locale shares" asks, or a decision saying why an
+  address that carries no locale stays per-locale.
+- Accept a middle name, and draw a shipped `personnummer` inside a *selected* sex;
+  both want a draw group sharing its family's pins. Stop the conflict error naming a
+  rewrite that returns a different value where the read it conflicts with sits inside
+  another category, and report a struct column's draw conflict with the path spelling
+  a tag takes.
+- Let `geo.SE.locality[Lund].address` descend from a selected row into the template
+  beside the family: require the path step to reach a sibling category, and seed every
+  draw group of the render from the outer selector's pins.
+- Read `email.local`'s and `username`'s handles from the shipped name tables, which
+  goal 12 asks for and the hand-written list they use today does not meet. Keep the
+  handle shape: `username` shortens a surname to `ahl` or `sjo`, and the US one draws
+  unisex given names, neither of which falls out of the tables unaided.
+- Decide whether `email.local` and `username` share one list: a reference between
+  shipped categories breaks a consumer once tagged, so it rides a 0.(x+1).0 after that.

-#### Order of work
+- Name a spelling that works when a row selector misses: `misc.protocol[tcp]`,
+  `misc.httpmethod[get]` and `misc.territory[se]` all answer "no row … has key or name"
+  and stop there, where a case-insensitive match could name the row that exists, and a
+  table with no `name` column could say it selects by key alone. `misc.tld[se]` misses
+  on the leading dot its keys carry rather than on case, and `misc.loglevel[Error]`
+  misses although a column carries `Error`, so the near miss is worth naming whatever
+  shape it takes.
+- Let a table column carry a `datatype`, so `--format json` writes
+  `"safe": true` and `--format sql` a boolean rather than the text `'true'`. Today only
+  a JSON field takes one, so `misc.httpmethod`'s booleans are typed in Go and text
+  everywhere else. Typing a shipped column changes what `json` and `sql` write, so the
+  capability is a minor and applying it to `misc.httpmethod` is a major.

+  the four zones most Americans live in to 278, and dropped `America/Indiana/Petersburg`
-  own browser.
+  (pop. 2,400) from 17 draws to 0.
+- Rewrite `CHANGELOG.md`'s `[Unreleased]` as what v0.1.0 holds: nothing has shipped, so
+  "no longer paths", "where it used to fail" and "where it used to be an empty string"
+  describe versions no reader can have installed.
+- Ship prebuilt binaries so the CLI needs no Go: GoReleaser attaching them to the Gitea
+  release the tag workflow publishes, a container image, Homebrew and Scoop. A checkout
+  build prints `devel` for `--version`; the binaries carry the stamped tag.
+
+## v0.2.0
+
+- Ship the full registers as packs, each a Go module with its own `embed.FS` and a zip
+  for `--data-path`: every US place of 10,000 and more streets per locality, built by
+  `--min-population` and `--streets-per-locality`. The default embed stays under ~1 MB
+  per country and `New` under ~50 ms.
+- Add the locales nb_NO, da_DK, fi_FI, de_DE, en_GB, nl_NL, fr_FR and es_ES, with
+  person, address, phone, national id, company and date names each, and the `geo/`
+  trees NO, DK, FI, NL, FR, AU, CA, ES, GB and DE their `address` reads by reference;
+  AU and CA get a tree with no locale of their own.
+- Add `{btc()}` and `{eth()}`, which need sha256 and keccak for Base58Check and EIP-55.
+- Pair a street with its exact postnummer, which needs an application to Lantmäteriet;
+  today a street goes to the nearest postal code centroid. It rewrites shipped rows, so
+  it is a major once 1.0 is cut and a minor before that.
+
+## v0.3.0
+
+Names no items yet, so planning it is a chunk of its own: it takes the additive work
+that lands after v0.2.0, and it has to add something, since a minor only adds. Its job
+is to be the release with no breaking change that v1.0.0 waits on — v0.2.0 cannot be,
+because pairing a street with its exact postnummer rewrites shipped rows.
+
+## v1.0.0
+
+- Cut it once the shipped data is in its record shape and one full minor has shipped
+  with no breaking change, per the README's Versioning table: v0.1.0 settles the
+  record shape and v0.3.0 is the quiet minor.
+- Announce it where a developer choosing a fake-data tool already reads, which is
+  goal 1's second half and waits for the tag: complete, stable, installable without
+  Go. Write the README's first screen for someone deciding in a minute.
+
+## Not release-bound
+
+- Stop `/cache` collecting root-owned files, which today every command documented
+  without `--user` leaves for the next `--user` one to trip over, and which the README
+  answers with a chown a reader has to repeat. Put `--user` on all of them, or give the
+  `x-go` anchor a `user:` — that one needs a mechanism, since Compose interpolates from
+  the process environment and neither `UID` nor `GID` is exported there, so
+  `user: "${UID}:${GID}"` resolves to `":"`.
+- Publish a homepage with an in-browser generator: the library compiled to WebAssembly,
+  so visitors generate as much data as they like in their own browser.
