Details

1. Bind a pick to a name with {x as n}, read it with {n} and {n.path}, and refuse a name bound twice.

• A name is one pick of everything under it, drawn once: {/country as k} {k.city.name} ({k.city.population}) is one city of k's country.
• A name is visible in the template that binds it and everything that template renders, its sibling fields and a record's columns included, so one field may bind and another read.
• A name bound inside a repeat level picks again on every iteration; one bound outside it keeps its pick on every line.
• Refused at load: a name bound twice in one scope, and a name that is also a field or an option of the template, since options and fields share one namespace.

3. Rewrite the shipped categories so facts that belong together come from one named pick.

• sv_SE.person and en_US.person bind the first name and read sex and title through it: "first": "{.first-name as n}{n.name}", "sex": "{n..sex.name}", a title from {n..sex.title.name}.
• geo.SE.address and geo.US.address bind the street and read locality, postal code and region through it; the locale address categories bind /geo.XX.address once.
• Needs items 1 and 2. Every shipped value must still pass its consumer's check before and after item 4.
• Re-pin seeded output in its own commit.

4. Draw every {…} afresh, keep a pick only by name, and delete drawGroup with the fences that held picks implicitly.

• Needs items 1–3. After it, {/person} ({/person.first}) renders two people, {w} {uppercase(w)} renders b G where w is a choice of letters, and {/city.name}, {/country[SE].name} and {/country[SE].name} / {/country[NO].name} both load.
• Deletes the token-order rules (drawsApart, readFold, branches, the pairwise replay), the expansion hold fence, drawGroup, the own-family fence and the cell-reference fences, and revises the decisions that point here. The remaining draw checks are names, paths through names, cycles and the repeat cap.
• Fixes on the way: {/sel}|{/sel} panics out of Fake today where two draws land on rows whose cells select different rows of another table; it must render.
• Rewrites the README's References, Draw group, Correlated fields, Linked tables and "One draw, one spelling" sections; the Linked tables section says which pick's weights govern a family, since the bound row decides.
• Re-pin seeded output and testdata/shipped_shape.txt in their own commits; the CHANGELOG names the grammar change.

25. Draw en_US.phone's exch as a NANP central office code, and assert the rule in TestShippedUSPhone.

{int(100,999)} renders a leading 1 in about an eighth of draws, which libphonenumber rejects, and the test proves the shape rather than the rule.

59. 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.

2. Step up from a row to the row it links to with ..: {/city[Oslo]..country.name} renders Norway, and city[Oslo].country stays the cell NO.

• .. goes up one level, to the parent table, and the name after it is that parent's: {c..country.name}, and from a locality {l..municipality..region.name}. Naming any other table is a load error naming the parent.
• It steps up from a selected row, a drawn row or a name bound to a row.
• After .., . steps down again: {c..country.city.name} is a city of c's country, drawn afresh.
• .country after a row keeps reading the link column's cell, so the README's city[Oslo].country example stays true.
• A Fake path and --list take .. too; List keeps advertising direct descents only.

26. 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.

35. Add {isin()}, {cusip()}, {aba()} and {vin()}.

isin: Luhn over letters expanded to digits. aba: 3-7-1 weights. vin: position 9 over the whole; a sample taking the WMI, since the check sits mid-string.

12. Strip the whitespace data-import/territory.py copies from its register.

misc.territory[CW].capital renders Willemstad, with a leading space.

5. Run the nine-seat comprehension panel after the draw restructure, and file what it names.

Needs item 4, and runs as item 6 decides.

37. Report every mistake a load finds in one error, as the decision "A load reports every mistake at once" states.

New and NewTemplate stop at the first, so data holding two mistakes takes two runs to fix. Split it into items before starting, one of them the shape a Go caller iterates and the CLI prints, and the order of an inline template's mistakes, which name no path; reword the README's "New refuses a mistake in the data" to every mistake.

60. Ship prebuilt binaries, a container image, and packages for Homebrew, Scoop and the biggest Linux package managers, so the CLI needs no Go.

GoReleaser attaches the binaries to the release the tag workflow publishes, and builds deb and rpm packages, an Alpine APK and an AUR package beside Homebrew and Scoop. A checkout build prints devel for --version; the binaries carry the stamped tag. v0.1.0 ships first, so it can be tested before it is packaged.

6. Decide how the comprehension gate treats panel noise: identical code scored 5.7 and 5.4.

Two nine-seat runs on 5cb919e, same briefs, same model, 2026-09-30:

Seat	Run 1	Run 2
Junior A	5	5
Junior B	4	5
Mid A	6	5
Mid B	6	6
Senior domain	6	5
Senior maintainability	6	6
Senior extender	6	5
Architect greenfield	6	6
Architect inherited	6	6
Mean (Navigation / Locality / Shape / Self-sufficiency)	5.7 (7.0 / 5.1 / 5.9 / 5.7)	5.4 (6.3 / 4.8 / 5.8 / 5.3)

Both runs named the same hardest units, drawsApart and readFold.reads. Run 1 is the recorded score; run 2 reran the same code to measure noise. A spread of 0.3 is close to the whole 5.7–6.1 range the recorded scores span since 2026-09-20, so AGENTS.md's "no merge lowers the last score" can block or pass a chunk by chance. Until this item is decided, that rule compares against 5.7, from 2026-09-30.

42. Key every table by one key column, as the decision "A table selects by one key column, a code, never a free-form name" states.

geo.SE.municipality[Lund] and misc.territory[Sweden] select a row today. Steps:

• Have a selector that misses name the key of every row whose cell spells it, matched without case, else say the table selects by its key: misc.territory[Sweden] and misc.territory[se] name [SE], misc.protocol[tcp] its key, and misc.loglevel[Error] [err].
• Delete the name option and the load checks it carries, and have New refuse a table still carrying name, naming key.
• Key misc.loglevel on keyword, and geo.SE.locality on the integer data-import/geo-se.py assigns as the decision states, linking street and postal-code by it.
• Drop key from last-name and sv_SE.title, and re-pin testdata/shipped_shape.txt.
• Leave no selection by name in README.md, CHANGELOG.md, docs/ or --help.

54. Name the file a link error comes from beside its category path, sub.x (/d/a/sub/x.json): ….

With several --data-path layers the author has to work out which directory won, while a parse error on the same file names it.

28. Accept a middle name, and draw a personnummer whose sex matches a sex selected through a named pick.

Needs item 4.

24. 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.

55. Let a table column carry a datatype, so --format json writes "safe": true and --format sql a boolean.

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.

15. Add the remaining misc tables and templates, one row of its detail's table per chunk.

Shape: T = table, t = template, c = choice.

32. Rename misc.territory.country to sovereign.

It holds a code, and country collides with the misc.country path it replaced.

45. Have misc.tld[se] select the row keyed .se, or have its miss name [.se].

The decision "misc.tld keys carry the leading dot, where other tables key on a bare code" leaves misc.tld[se] missing today.

20. Weight sv_SE.sex and en_US.sex by bearers, as the README's Data section says they are.

Neither names a weight, so a bare sex draws evenly.

52. Reword prove's refusal of a typed column reading a row, {/region}.

Say the format is the table's own (region's format "{name}"), name the read to write, {/region.<column>} with its columns, and stop calling a one-column format, {code}, composed text.

56. Read the tag through git/ref/tags/{tag} in publish_release.py.

GitHub answers tags/{tag} with 404 whatever exists, so the burnt-version guard never fires and a release lands on a tag already pointing at another commit.

17. Give every shipped category a column for each part its format composes, and one record shape across the national ids; re-pin the shape.

misc.uuid gains variant, for one.

49. Refuse a Fake path into a level carrying a repeat, as the README's Correlated fields section states.

probePath skips pathCheck.enter, so Fake("x.a") under "repeat":3 renders one draw.

22. Give url and email a path that draws only domains nobody can register, keeping the wide set as the default.

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.

29. Let a path go from a selected row into the template beside its family: geo.US.locality[1714000].address.

Require the path step to reach a sibling category.

43. Refuse a struct tag's datatype naming the Go type that sets it before proving its values, as the README's Library section promises.

datatype: boolean over {int(1,2)} on an int field answers prints an integer, not a boolean.

47. Report the same error every load for a table with two bad options, and for a folder with two unnamed rows files.

readTableOptions and loadDir return on the first in Go's map order.

14. Spell misc.creditcard's digit runs {digits(n)}, and refuse a repeat over a lone {digits(1)} at New, naming that spelling.

Both render the same run.

39. Compare calcParser.binary's operator as a rune.

byte(p.rs[p.pos]) reads U+012B ī as +, so {calc(a ī b)} compiles as a + b.

46. Name the node a selector follows in stepInto's refusal.

sv_SE.person[1].first answers 1 is not a table.

51. Report a CRLF rows file holding only its header as having no rows.

parseRows answers "line 2 is empty".

13. Place xlsx cells by their r reference in data-import/xlsx.py.

A sheet omitting an empty cell shifts every later column left.

40. Stop the columnKinds suggestion naming a field's own kind or a narrower one.

An int64 or float64 field unproven in range is told to become itself, and a uint64 one to become int64.

53. Spell a table one way across the errors that name it.

pinRow names t.path and mustRow panics with t.category, so one table is territory and misc.territory, and the short spelling names no file where two folders hold that name.

10. Test that every node kind reaches each switch over node kinds.

Needs item 4; recount the switches then. Today ten, from render to columnItems, must agree, and only render and renderEdges say so.

11. Test that every geo tree holds the five table names and the address columns that port across countries.

Nothing checks it, and a new country breaks it silently.

23. Give every other shipped category that could reach something real a path that never does.

phone draws live PTS and NANP ranges — PTS's five fiction series are the Swedish inert set, sourced in research-sources-se.md, and the NANP one still wants a source — and bankgiro, plusgiro and routing draw live prefixes.

8. Move binding, bind and checkNodeFences out of data.go into a file of their own.

The greenfield architect found the fence pipeline last. Needs item 4, which shrinks the pipeline.

9. Move table.route, selector, step and drawStep from path.go to table.go.

The inherited architect's 3am trace crossed four files for one draw.

41. Parse defaultTable's path with the library's grammar.

The CLI counts brackets of its own, so a change to the selector grammar desyncs the default --table silently.

48. Refuse a category naming a hidden rows file, "rows": ".x.tsv", as a rows file that is not there.

loadDir indexes hidden TSVs and skips them in two places, so one loads where its comment says a hidden file is never data.

7. Fill arm in one place.

splitArm runs before the link and again after it, and compileArm finishes it from reference.go, so five seats traced three phases. Needs item 4.

38. Rename newRand to newGeneratorState and Generator.rand to state.

Both name half of a generatorState, hiding its {seq()} counters, and New's local rng shadows the rng interface.

44. Call templateError a compile failure in its doc.

Its doc says render failure, and it wraps what NewTemplate and NewRecordTemplate refuse.

30. Read email.local's and username's handles from the shipped name tables.

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.

50. Print --help's repeat range from fejkdata.MaxRepeat.

The usage spells 1..1048576 a second time.

58. Build on a manual run of test.yml.

workflow_dispatch leaves github.event.before empty, so the diff compares HEAD with itself and skips docker build.

65. Pair a street with its exact postnummer.

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.

64. Add {btc()} and {eth()}.

They need sha256 and keccak for Base58Check and EIP-55.

63. Add the locales nb_NO, da_DK, fi_FI, de_DE, en_GB, nl_NL, fr_FR and es_ES, and their geo/ trees.

Each locale carries person, address, phone, national id, company and date names. Their address reads the geo/ trees NO, DK, FI, NL, FR, AU, CA, ES, GB and DE by reference; AU and CA get a tree with no locale.

61. Promise in Generator's godoc that its renders run one at a time.

A caller wanting parallel throughput then makes one generator per goroutine.

67. Hold every change AGENTS.md says owes a CHANGELOG.md entry to one in CI.

The check covers data and testdata/shipped_shape.txt alone, where AGENTS.md adds a flag, an exit code, an exported name, a fence, a builtin and the lowest Go.

62. 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.

68. Cut the README's Layout block to the lines that say what a file name cannot.

calc.go, doc.go and cmd/fejkdata/ restate their names.

69. Cut AGENTS.md to the rules only it states, and explain every term its comprehension rule uses.

The gh rule opens by restating the decision "GitHub is canonical, and the module path names it", a second copy that drifts. The comprehension rule packs the gate, its exceptions, the round and the at-or-above-7.0 regime into one line, and uses "depth 1", "nine-seat", "four-seat" and "answers it in one run" without saying what they mean.

66. Give every entry in docs/decisions.md the goal it serves, its date, who made it and the premise it rests on.

Propose a goal for an entry that serves none.

70. Make gitea.larvit.se/larvit/fejkdata a pull mirror of GitHub.

Gitea converts a repository to a mirror only by re-creating it, so until that runs the copy there is a second owner of one history.

71. Announce v1.0.0 where a developer choosing a fake-data tool already reads, with a README first screen for someone deciding in a minute.

The human cuts v1.0.0 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; v0.2.0 rewrites shipped rows, so a v0.3.0 with no breaking change comes first.
