+# Package test cases --- why they are built this way
+
+What to do is in [WIP.md](WIP.md) (*Where things live*, the contributed packages) and in
+[test/package-tests/README.md](test/package-tests/README.md). This file says why.
+
+## What the test cases are for
+
+A contributed section's NOTEs and WARNINGs are claims about someone else's code: that a member
+raises 53, that a match is cut short, that a dialog ignores a property. Each was true of one version
+when an agent checked it, and nothing kept that evidence: the probe pages were deleted after use.
+So the claims are written down as cases that persist, run again whenever the package's version
+moves, and say which claims no longer hold. The owner wants the same cases to be usable by the
+package's author, which decides most of what follows.
+
+## A case checks what is correct (owner)
+
+A case asserts the behaviour the package should have, not the behaviour it has. To the author a
+red case is a defect to fix and a green one is done, with a message that reads as a bug report.
+The documentation needs the opposite question answered too (does the page still describe the
+package?), and `expect.json` answers it: it records, per case and architecture, the exact failure
+report or that the case never returns, on the documented version. The runner's three verdicts
+come from comparing the two: *documented*, *fixed* (the callout goes, by the rule that the
+documentation is not a record of past defects), *changed*.
+
+The failure report is compared exactly, after the line number and the assertion prefix are
+stripped, so a defect that changes shape (a different wrong value) is *changed*, not
+*documented*.
+
+## Expect, not Assert (owner)
+
+twinBASIC's own form is a `[TestFixture]` module of `[TestCase]` Subs checked with the Assert
+package, and `tbrun --tests` runs those in the compiler's test mode. But in BETA 1005 the IDE has
+no way for a person to run a test case, and outside test mode a failed `Assert` stops the run at
+the error panel, uncatchable by `On Error` (WIP.Harness.md, *Running a project's test cases*). An
+author who opens the project would see the first failure only. So the cases check through
+`Expect.twin`:
+
+- **Under `RunAll`** (the project's `Sub Main`, which an author runs with F5), `Expect` collects:
+  `Expect.Done` records the case's report, and `RunAll` calls every case under
+  `On Error Resume Next` and prints `PASS`, `FAIL` or `SKIP` for each.
+- **Under `tbrun --tests`**, `Expect.Done` ends a failed case with `Assert.Strict.Fail` and the
+  whole report as its message. An `Assert` failure is the one thing a case's own
+  `On Error Resume Next` cannot hide; an `Err.Raise` from `Done` would be swallowed by it and
+  the case would pass. Checked on BETA 1005: the message comes back whole in the response's
+  `body.error`.
+- Every check of a case runs, and `Done` reports all failed ones, so one run of a case shows
+  every defect it covers.
+
+The `[TestFixture]` and `[TestCase]` attributes stay, so the cases are in twinBASIC's own form
+for whatever runner the IDE gains. `RunAll.twin` is generated rather than written, because a
+hand-kept list of calls drifts from the cases; the gate refuses a stale one.
+
+## A case that never returns
+
+Some defects are a loop that never ends (BigNumberLib's modular inverse of zero, TBMANLIB_Xml on
+some malformed text). In test mode such a case holds the compiler: `tbrun` gives up on it after
+its timeout, and every case after it would time out too. So the runner, on a case that does not
+return, records it and runs the cases after it again in a new IDE; once `expect.json` says
+`hangs`, the case is run alone with a short timeout, and `RunAll` skips it, because an author's
+IDE would hang.
+
+## The download carries no package (owner)
+
+Embedding the package in the published file would mean either the build fetching from TWINSERV
+(the deploy then depends on that server) or committing every documented version's `.twinpack`
+(about 35 MB, some of it WinDevLib, and four packages declare no licence that allows passing them
+on). The owner chose neither.
+
+The published project keeps the template's reference to the package and has no `Packages/`
+folder, which makes it a **linked** reference. Checked on BETA 1005 (private APPDATA, private
+desktop):
+
+- With the package's `.twinpack` in `%APPDATA%\twinBASIC\packages`, the project compiles. The IDE
+  finds the file by the package's project id, whatever its name, and takes the version from the
+  file: a 1.7.0.0 file under a reference that says 1.8.0.0 compiles against 1.7.0.0.
+- Without it, every name of the package is TB5079, and Enabled Libraries shows
+  `[LINKED-PACKAGE] ... ERROR unable to load this reference`; its FIX link is not implemented.
+- A file put in the folder while the IDE runs is used after Restart Compiler.
+- Nothing downloads a missing package by itself. The IDE's only download path is the Available
+  Packages tab (`importPackage` in `main.js`); a project load calls only `/packages/checkVersions`,
+  and only for a reference with a `publisher` field. `path32`/`path64` set to a file path or a
+  TWINSERV URL, or a `.twinpack` beside the project, are not used.
+
+So the reader puts the documented version's file in the packages folder (or adds the package from
+Available Packages with Embedded cleared) and restarts the compiler; an author points the folder at
+their own build. The runner embeds the package from `%TEMP%\tb-twinserv` instead, as
+`check_examples` does, so it never touches a packages folder.
+
+## Markers, and a gate that only tightens
+
+A callout names its cases in an HTML comment on the line above it. The marker lives with the
+callout, so moving or rewording the callout keeps its tie, and it is invisible on the page. The
+cases name nothing back: a case file referring to a page and a heading would break on every edit
+of the page. The gate checks both directions (an unmarked callout, an unnamed case) from the
+sources alone, so it runs in `test.bat` and CI, where the cases themselves cannot run.
+
+The sections were written before any project existed, so the gate starts with every section in
+`PENDING` and fails on a section that has a project and is still listed, or has none and is not:
+the list can only shrink, one package at a time.
+
+`none -- <reason>` exists for a callout no program can check (a fact about the IDE, a licence); it
+keeps the decision explicit and visible in review, where a missing marker would be ambiguous.

-Three things combined:
+`## Methods`. Every member documented at `###` (`Line`, `Print`, `Cls`, the
+Assert methods, and about 2,700 others) shares the situation. Three things
+make such a member hard to find, and each shapes the design:
 
 1. **Granularity.** [builder/search.mjs](builder/search.mjs) splits a page into

-   member became part of the text of its parent `##` entry, often 5 to 16 KB

+   one entry per heading up to `search.heading_level`. At level 2 a `###`
+   member is part of the text of its parent `##` entry, often 5 to 16 KB
+   long, and a search shows it as an entry titled just "Methods" that links
+   to `#methods`.
 2. **Length normalisation.** lunr scores with BM25 (`b` = 0.75). A term found
    in a 10 KB "Methods" entry scores far lower than the same term in a short
    entry that only mentions it, such as the glossary's "graphics method".
-3. **Tokenisation.** The client split on `/[\s\-/]+/`, not on `.`. So

It is adapted from primary sources: Microsoft VBA-Docs (CC-BY-4.0) for the runtime library, `.twin` source for the twinBASIC-specific packages. The CEF and WebView2 packages also carry a tutorial set.

The two console packages carry a NOTE (owner, 2026-10-12) that the samples harness cannot yet capture a console, so their console claims follow the source. Generics (seven tuple classes) and xCalendar (one control) are each one page (owner, 2026-10-11 and 10-12), so `analyze` in audit mode lists their classes and members as undocumented.

Fmt documents its test code (`HelloWorldClass`, `HelloWorldModule`, `Pootle`) in one paragraph of its landing page, which `exclude_from_docs` names; Generics' `exclude_from_docs` names its test code, `HelloWorldModule`, which the page does not mention. VBComDlg's `exclude_from_docs` names `CommonDialogBase`, a module whose public procedures only its class calls. tbRegExp's `exclude_from_docs` names its private engine module, `StaticRegex`, and tbProjPacker's its helper modules, `modImpExp` and `modWin32`: the indexer counts a Public Enum as public even inside a Private Module, because a built-in package's are reached through its library symbol written with an asterisk (`*WinNativeCommonCtls`, as `ImlDrawConstants` says). By its bare name no such enum is reachable, in a built-in or a contributed package (TB5079 on BETA 1005). OLEGuids documents each interface's methods on the interface's page. What TBMANLIB_Dialog's pages say its dialogs do comes from `test/package-probes/TBMANLIB_Dialog/`, which operates them in a built exe on a private desktop; run it again when the package's version changes. TBMANLIB_Dialog 1.1.0.0 has a page of its own for each class except cDialog, which keeps a page for each member, so `analyze` in audit mode lists the members of those one-page classes as undocumented; its `exclude_from_docs` names its test module, `TestModule`, and the seven COM interface declarations that cDialogEx calls inside (`IOleWindow`, `IModalWindow`, `IShellItem`, `IShellItemArray`, `IFileDialog`, `IFileOpenDialog`, `IFileSaveDialog`), which its landing page describes in a paragraph. cDialogEx 1.1.0.0 returns the name of the chosen file, not its path, ignores `InitialDir` and ignores a `Filter` that has no closing pipe, each documented as a WARNING. tbRegExp is the first section drafted by the doc-draft workflow ([WIP.Indexer.md](WIP.Indexer.md#draft-and-the-doc-draft-workflow)), then reviewed against the sources, the package's README and VBScript's own **RegExp** under `cscript`. tbRegExp 1.7.0.0 is Contributed although a match is at most about 3,300 characters long: its engine gives up a search from one start position after 10,000 steps, a limit fixed inside the package (`a*` on 5,000 `a` finds 3,331 characters from position 1669; confirmed by a second agent, and the same limit is in upstream vba-regex, where a caller can raise it), stated in a WARNING at the top of its landing page and in its line in `Contributed.md` (owner, 2026-10-13).

The package is type-only — it ships **public interfaces + CoClasses** that an addin DLL binds to; every implementation behind them lives in the twinBASIC IDE itself. The user-facing surface is one entry-point factory (`tbCreateCompilerAddin`) plus 23 CoClasses grouped by role: the addin contract (`AddIn`), the root API (`Host`), the loaded `Project`, the editors collection (`Editor` / `CodeEditor` / `Editors`), the virtual file system (`FileSystem` / `FileSystemItem` / `Folder` / `File`), the in-IDE UI surface (`Toolbar` / `Toolbars` / `Button` / `ToolWindow` / `ToolWindows`), the HTML DOM inside a tool window (`HtmlElement` / `HtmlElements` / `HtmlElementProperty` / `HtmlElementProperties` / `HtmlEventProperty` / `HtmlEventProperties`), the `DebugConsole`, `KeyboardShortcuts`, `Themes`, and the single concrete user-instantiable helper class `AddinTimer`. Flat layout — one page per CoClass / Class plus the index landing.

Next to the author, on the same line, `**Version:**`: the version the section documents, which is its `indexed_from` and changes with it (owner, 2026-10-12). Then `**On GitHub:**` with a link, when a repository holds the package, or the library the package says it is made from; search GitHub for the package's name and the author's account, and check that the repository holds the package's code (its history too: `TBMANLIB_*` were never in woeoio's `tbman`). A landing page with one or two sections has no `* TOC` list. A class with member pages is a folder, `<Class>/index.md` at `/tB/Packages/Contributed/<Package>/<Class>/` with its members beside it, so a member links to its class as `(.)`; a class documented on one page is `<Class>.md`. Each package is a chapter of the book's Packages part in `_book.yml`. A section's `indexed_from` is the four-part TWINSERV version, and its snapshot is under `indexer/snapshots/contributed/`. Its samples compile in the `contributed-<Package>` sample template, whose `Settings` names the package's version: **change that version with `indexed_from`** ([WIP.ExamplesBuild.md](WIP.ExamplesBuild.md#template-projects)). **A contributed package is documented and its samples compiled against the newest twinBASIC BETA installed, never an older one** (owner, 2026-10-11): the version that matters is the package's, and a statement about the compiler (such as "does not compile on BETA 1005") names that newest build. **A contributed package that does not compile on that build, or has defects that a program would meet, is listed under Experimental Packages** (owner, 2026-10-12); a minor defect that the section documents does not make it Experimental (owner, 2026-10-12: VBComDlg, whose Replace All raises no event, stays Contributed; owner, 2026-10-13: a fixed limit that the section states at the top of its landing page does not either, as tbRegExp's match length). **A package moves from Contributed to Experimental for its defects only after a separate agent has reproduced each defect independently** and ruled out misuse, a wrong expectation, a twinBASIC defect and the harness (owner, 2026-10-12): `docs/Reference/Experimental.md`, at `/tB/Packages/Experimental/`, after Contributed Packages. Its landing page's `parent:` is `Experimental Packages`, its line is in `Experimental.md` and not in `Contributed.md`, and its book chapter follows the Experimental Packages chapter. Its folder and URLs stay under `Contributed/`, so a package that is fixed moves back by changing only those three, and its pages keep their addresses.

A difference from the object the package replaces that gives a different result silently (tbRegExp's `\1(a)`, `{,m}`, `$~` against VBScript) is a NOTE, not a WARNING (owner). A case checks what is correct, not what the package does (owner): a defect is a failing case, recorded in the project's `expect.json`, so the project tells the package's author what to fix. A section whose project is not written yet is in that gate's `PENDING` set. `package-tests.bat` runs the cases; a case it reports *fixed* means the callout goes. **The landing page ends, after See Also, with `## Test cases`**: one or two sentences linking to `<Package>-tests.twinproj` (owner), which the build publishes beside the section without the package's code in it (owner): it references the package as a linked package, which the reader puts in `%APPDATA%\twinBASIC\packages` ([WIP.PackageTests.md](WIP.PackageTests.md)). Its samples compile in the `contributed-<Package>` sample template, whose `Settings` names the package's version: **change that version with `indexed_from`** ([WIP.ExamplesBuild.md](WIP.ExamplesBuild.md#template-projects)). **A contributed package is documented and its samples compiled against the newest twinBASIC BETA installed, never an older one** (owner): the version that matters is the package's, and a statement about the compiler (such as "does not compile on BETA 1005") names that newest build. **A contributed package that does not compile on that build, or has defects that a program would meet, is listed under Experimental Packages** (owner); a minor defect that the section documents does not make it Experimental (owner: VBComDlg, whose Replace All raises no event, stays Contributed; owner: nor does a fixed limit that the section states at the top of its landing page). **A package moves from Contributed to Experimental for its defects only after a separate agent has reproduced each defect independently** and ruled out misuse, a wrong expectation, a twinBASIC defect and the harness (owner): `docs/Reference/Experimental.md`, at `/tB/Packages/Experimental/`, after Contributed Packages. Its landing page's `parent:` is `Experimental Packages`, its line is in `Experimental.md` and not in `Contributed.md`, and its book chapter follows the Experimental Packages chapter. Its folder and URLs stay under `Contributed/`, so a package that is fixed moves back by changing only those three, and its pages keep their addresses.

A top-level section between Features and Reference Section in the nav, at `nav_order: 6` (Features is 5). `index.md` is the landing page and `Getting-Started.md` the only page so far, with its screenshots under `Images/`. Everything it describes arrived in **BETA 984**. Its language claims are measured on BETA 995 with `tbrun --llvm` and `--exe`: the comma, space and comma-space spellings of `[CompilerOptions]` all turn LLVM and `+optimize` on, `[CompilerOptions("")]` turns it off under project-wide LLVM, the long CPU-flag sample runs, and an error is lost between procedures when either the callee or the caller is LLVM-compiled. Its samples are marked `check_build`, which compiles them; `examples.bat --llvm` also builds them with LLVM.

The compiler's `import` refuses a project that embeds a package (exit 999, twinbasic/twinbasic#841), and both verbs exit 0 after the failures they report. The reasons, and the path and stdin rules for anything that does run the executable (`bug_repro`'s `cli` mode), are in [WIP.Harness.md](WIP.Harness.md#getting-at-the-twin-sources).

 - **Keep a probe that might crash the compiler in a project of its own.** twinBASIC runs the compiler in the same process as user code, so one bad probe can take the run down and cost the other probes their answer.
 - **`tbrun` takes an exported tree, not a `.twinproj`**, because it has to pin `project.buildPath` in its own staged copy. A project still on the default template opens a native Save dialog that is invisible on the private desktop: the build never happens, while every health check says the IDE is fine. The probe is a module with a `[RunAfterBuild]` Sub, and must start with `Debug.Cls`. Its exit codes: 0 the probe ran and its output was captured, 1 the project has compile errors, 2 the harness failed or the build did after a clean compile, or, on a build before 1005, the probe's module holds a procedure named like the module, which stops the `[RunAfterBuild]` Sub from running there (`--allow-name-clash` runs it anyway), 3 no output, 4 the compiler crashed, as `tbbuild` reports it, 5 the probe ended before it returned (`End`, or an error raised with no handler in LLVM-compiled code, which ends the run silently), 6 with `--exe`, the exe exited with a code other than 0, the event log records that it faulted, it opened a box (an unhandled error opens one, and `tbrun` closes it), or it was still running at `--timeout`, 7 with `--tests`, a case failed.
 - **A project's own unit tests: `tbrun --tests`.** It builds nothing: it runs each `[TestCase]` Sub of each `[TestFixture]` Module in the compiler's test mode, the debugger's `evaluate` request with `isTest`, which the IDE itself never sends (BETA 1005 has no test runner a person can use), and prints `PASS` or `FAIL` for each. A failed assertion, an unhandled error and an access violation each end only their case. A defect that is a diagnostic is a compile case instead, a line ending `' CASE <Name>: <codes | error | none>`.

A case that never returns is caught and run alone. It also rewrites the generated `RunAll.twin`. Outside every gate and CI, as `examples.bat` is. The build publishes each project, referencing the package as a linked package and carrying none of its code, as `tB/Packages/Contributed/<Package>/<Package>-tests.twinproj` in the online tree (the `packageTests` task, `builder/package-tests.mjs`, `_config.yml`'s `package_tests`; the publish allowlist exempts those paths, and the offline tree's links go to the website).
 - `addin-test.bat` — tests IDE add-ins by operating an IDE: every lane in `test/addin/lanes.mjs` builds the add-ins it tests into a private copy of the install, opens a project and checks what the add-in does. Outside every gate and outside CI for the same reasons as `examples.bat`; about two minutes for the seventeen lanes today (BETA 997): Samples 10 and 15, the thirteen probe lanes behind Stage 2's answers in [WIP.HelpAddin.md](WIP.HelpAddin.md), and the help add-in in `add-in/` twice, built with its committed copy of the symbol index, `add-in/Resources/SYMBOLS/symbols.json`, which a local build rewrites whenever the index changes. The `help` lane serves the built `docs/_site` on localhost to the add-in's pane; `help-offline` builds the add-in with a help archive of `docs/_site-offline` and the pane's pages come from the add-in's own server. So run `build.bat` first. Exit 0 every lane passed and the registry is as it was found, 1 a lane failed, 2 the harness failed, 3 the registry or a work folder was not put back. See [Driving the twinBASIC compiler](#driving-the-twinbasic-compiler) for its rules.

Needs `build.bat` first. Exit 0 closed and put back, 1 the add-in or the project did not compile, 2 the tool could not run, 3 not put back.

One setup is not an IDE: `web` starts puppeteer's Chrome through `launchOnDesktop` on a private desktop of its own (never headless, never on the user's desktop; native-window occlusion and occluded-window backgrounding switched off, or a capture waits forever or comes back blank) for the two public pages the FAQ shows, taken once; it needs the network, as do `webpage` (the Webpage pane on `https://docs.twinbasic.com/`, its page captured from the pane's own DevTools target and pasted into the pane's place) and the package-server setups, which never publish. Every IDE gets `--force-device-scale-factor=1` (`Lane`'s `browserArgs`), else the page follows the display's scaling; the page is overridden to 1280x880 at 2x, and `PAGE_DEFAULTS` puts the IDE's options, panel layouts and keyboard groups to their defaults and the recent lists to the tool's own **in the page only**, its save calls replaced first so nothing is written. Each picture is a `Page.captureScreenshot` with a `clip`; a page showing it gives it `{:width height}` of half its pixel size. **Every picture is taken in two themes by one IDE**: dark as `X.png`, then, after `backToPrepared` and `tbTheme_SwitchToLightMode`, Light (not Classic) as `X.light.png` beside it, which the build pairs by name ([WIP.Build.md](WIP.Build.md#pictures-in-two-themes)); a light picture with the dark one's pixels is not kept, and one more than 32 device pixels off the dark one's size fails (a wrong state, not the theme). A label's pill follows the theme unless the shot names a `tone`. A shot's `annotate` list (arrows, rings, badges...) is drawn by `scripts/lib/shot-annotate.mjs` as one SVG layer over the page before the capture and removed after it, the clip growing to hold it. A picture is rewritten only when its bytes differ, and a second run reports every one `unchanged`; a capture is not byte-stable, so `capture` takes up to eight and keeps one equal to the file on disk, and a picture that differs from the file only by a capture's noise (16 grey levels, 0.5% of its pixels) is left as it is. `--jobs N` (default 6) runs the setups at once on their own ports and desktops, a full run in about 200 s (`--jobs 1`: one at a time); `--diffs <dir>` writes the old picture, the new one and an amplified difference map for each that changed, named with its theme. Settle by a condition, never a fixed sleep, and a picture that shows some state sets it itself rather than relying on the shots before it. The page's animations and carets are switched off through a style sheet put into the document and every shadow root; a picture that holds DEBUG CONSOLE lines has their times (and a CodeLens run's time taken) set in the page once the real ones show. **A running program's window** (setup `programs`, fixture `test/shots/programs`) is taken **once** (`once: true`, the dark pass only) with `captureWindow`, cropped to its visible frame, at the display's DPI, shown at its size at 96 DPI. **The Windows user name must never be in a published picture**: the visible text of the page, text boxes included, is searched for it before the first capture and again when a capture is chosen, with the picture's SVG under `--svg` (a page can draw again in between: Project Settings once put a real path back over the one the shot set), and for a program's window the texts of the window and its children, and the run fails when it is there. The tool finds each name it presses F1 on by searching the demo's source, not by line. The add-in is built on a port of its own (`Lane.addAddin`'s `port`): the building IDE's WebView2 process can hold its port after the IDE ends for longer than `launchIde`'s ten seconds. **`--svg`** also draws each picture as SVG from the page as it stands at the capture (`scripts/svgshot/`: a DOM snapshot converted, its text set in per-picture subsets of the fonts the IDE drew it with, cut by `scripts/subset_font.py`, which needs Python with fontTools), compares it with the PNG, and writes `X.svg` or `X.light.svg` beside it only when no more than 0.25% of its pixels are far off; otherwise an older SVG is removed and the page shows the PNG ([WIP.Build.md](WIP.Build.md#pictures-as-svg)). With `--svg` each picture's *bundle*, what its SVG is drawn from, is saved in the gitignored `.svgshot-bundles/` (`--bundles`; never under `docs/`, a bundle holds the user name), and **after a change to the converter, `node scripts/svgshot/replay.mjs` draws every SVG again from the bundles, with no IDE**, in about 20 s for the 370 (an SVG the same as its file is not compared again, `--recheck` compares all; the fonts' cuts are kept in `.svgshot-bundles/subsets/`; one browser per process, GPU off); it lists the pictures whose bundle cannot answer what the converter now asks, with the `--only` command that retakes them ([WIP.Screenshots.md](WIP.Screenshots.md#pictures-as-svg)). `node scripts/svgshot/bench.mjs` tests the converter's replicas of what Chromium draws outside the DOM (scrollbars, drop-down lists) in Edge, with no IDE ([WIP.Screenshots.md](WIP.Screenshots.md#pictures-as-svg)).

Run `build.bat` first.
+- `node scripts/shoot_docs.mjs` --- writes the documentation's IDE screenshots (plan and owner's decisions: [WIP.Screenshots.md](WIP.Screenshots.md)). Each picture is a shot in a table, `out` its path under `docs/` (`--only` matches it), in a setup (the main three below; the full list is in WIP.Screenshots.md), each one IDE on a **private** desktop started only when a shot in it is selected: `help` (builds the add-in as `try-help-addin.bat` does, opens `test/addin/helpdemo`, `TB_DOCS_HELP_REAL_TITLEBAR=0`: the eight `docs/IDE/AddIns/Images/Help_<Name>.png`), `no-project` (`Lane.openNoProject` with `includeProjects`: the menus, cut out with alpha, the dialogs that need no project, and the empty panels, each floated on its own, after the dialogs) and `project` (the demo without the add-in: About, which needs the compiler's licence answer, and IDE Options, whose font lists need a project). One setup is not an IDE: `web` starts puppeteer's Chrome through `launchOnDesktop` on a private desktop of its own (never headless, never on the user's desktop; native-window occlusion and occluded-window backgrounding switched off, or a capture waits forever or comes back blank) for the two public pages the FAQ shows, taken once; it needs the network, as do `webpage` (the Webpage pane on `https://docs.twinbasic.com/`, its page captured from the pane's own DevTools target and pasted into the pane's place) and the package-server setups, which never publish.

Run `build.bat` first.
 - **The help add-in's project file is written by every build, CI's included.** The `addinProject` task (`builder/addin-project.mjs`) packs `add-in/` into `tB/IDE/AddIns/downloads/tbDocsHelp.twinproj` in the **online tree only**, which the Help Add-In page offers as a download; `_config.yml`'s `addin_project` declares both ends, so a fixture config gets none. It waits for the `helpArchive` task. It packs the files `git ls-files` lists there, read from the working folder, never a `Resources/HELP/` file from the disk, with CRLF made LF outside `Resources/` (so a Windows and a Linux build write the same bytes), the `tB/symbols.json` the same build wrote in place of the committed copy, and **the zip that build's archive task wrote** as `Resources/HELP/site.zip`, passed in memory (a build that wrote none --- `--no-help-archive`, `--serve`, another `--dest`, a fixture --- packs without it, and the summary line says `without the offline archive`). The download is about 28 MB with the archive, 1 MB without. The offline tree holds no copy (the project carries that tree's archive, so a copy there would be circular), and its links to the file are rewritten to the website by the general rule in `offline-rewrite.mjs`: a URL the offline tree lacks but the online tree has becomes `site.url` + path, and is no miss (`computeWebsiteUrl`; the offline link check's `forbidExempt` excuses exactly those links, `isWebsiteOnlyLink`). The pack is `importProject` from `scripts/impexp.mjs`, the one module under `scripts/` that `builder/` may import (`biome.jsonc`); `check_tree_fresh.mjs` watches it and `add-in/` for that reason. The publish allowlist exempts the one path in the trees only (`publishPolicyFor`'s `generated`); a `.twinproj` anywhere else, or in `docs/`, is refused. `--serve` writes it into its one tree; `--dry-run` writes nothing. A failure (no git) fails the build with exit 1 and the index audit names the missing file. **Don't build the DLLs in CI from it**: that needs a twinBASIC install; the download is the project, and the reader builds it. Why each of these: [WIP.Build.md](WIP.Build.md#the-help-add-ins-project-file); `test/addin-project.test.mjs` is the gate.
 - **The help archive is the `helpArchive` task of the build's graph.** `builder/help-archive-step.mjs` writes `add-in/Resources/HELP/site.zip` from `docs/_site-offline` through `lib/help-archive.mjs`, once every task that writes into the offline tree has finished (`flushJoin`, `scss`, `writeOffline`; the archive task lists exactly those) and **before** the Gantt injection, so the zip holds `BuildInfo.html` without the chart and `assets/images/gantt.svg` as the 105-byte placeholder the sources hold (it is a tracked static file, so the file list already has it). It reads the file back to verify it. A mismatch fails the build (exit 1). After the Gantt injection `recheckHelpArchive` checks that the offline tree on disk lists the same files as the archive and differs from it only in `BuildInfo.html` and `gantt.svg`; a task that wrote into the offline tree late fails the build there. The help add-in embeds the zip as a resource and serves the pages from it with its own server; a build of the add-in without it uses the live site. The file is gitignored (about 26 MB), so a build of the add-in from a clean clone is the online one until `build.bat` has run. The download carries the same zip (previous bullet). **`--no-help-archive` turns the step off, and neither CI workflow may pass it** (`check_ci_workflows.mjs` refuses it, in `ALLOWED.forbiddenBuildFlags`), because CI's published download would then hold no archive. It runs only for the guarded source tree (`docs`) built into the default `docs/_site-offline` (not another `--dest`, so `compare_trees` and `check_links_diff` leave it alone), never under `--serve` or `--dry-run`, never without an offline tree, and not keyed on `$CI`. There is no command-line tool for the archive: the `help-offline` lane makes its own with `writeHelpArchive`. The zip's format is fixed by the add-in's reader, which does no inflating ([WIP.HelpAddin.md](WIP.HelpAddin.md), Stage 4, increment 5).

 - `node scripts/vb6run.mjs <file | ->` and `node scripts/vb6run.mjs --docs [--only <regex>]` --- build and run VB6 code, so that what a sample prints in twinBASIC can be compared with VB6: a stand-alone file of statements or a `.bas` module, or `--docs`, which builds the documentation's `check_run` fences in VB6 and says for each whether it prints what its page says (`same`, `differs`, `not VB6`, `error`, `refused`; a `projname=` group is built as a project of its own, its `slot=file` fences translated into VB6 `.cls` and `.bas` components). It has no wrapper and is outside every gate and outside CI: it needs VB6 (`--vb6`, `VB6_EXE`, or the standard install folder). **Never start `VB6.EXE` from a shell**: in Git Bash `/make` is rewritten as a path and VB6 answers with a modal box on the desktop; the tool spawns it from Node with an argument array, and a sample that calls `MsgBox` or `InputBox` or contains `End` is refused. Its `Debug.Print` rewrite and its file translation have probes in `test/example-batches.test.mjs`, and its command-line cases are in `scripts/lib/cli-cases.mjs`; both need no VB6. What it relies on is in [WIP.ExamplesBuild.md](WIP.ExamplesBuild.md).
 
 Three generators sit outside that loop and produce committed artifacts rather than build output — none runs during a build, and none is needed for one. `python scripts/build_fonts.py` rebuilds the subset webfaces under `docs/assets/fonts/` and needs a network connection; `node scripts/build_dot_metrics.mjs` regenerates `builder/inter-metrics.json` from those webfaces and needs only a browser. See [Typography](#typography). `node indexer/twin-index.mjs derive` regenerates `builder/package-api.json`, the packages' declared API that the build's symbol index (`tB/symbols.json`, for the IDE help add-in) is annotated from; it needs a twinBASIC install (or `--release`), so **run it when the reference is re-indexed against a newer build** and commit it with the pages and the snapshots. See [WIP.HelpAddin.md, Stage 3](WIP.HelpAddin.md#stage-3-the-symbol-index-generated-by-the-docs-build).

+A known defect in twinBASIC follows the same scale. A defect that silently gives a wrong result --- a function that returns the wrong value and raises no error --- is a `> [!WARNING]` until a fixed build is released, because nothing tells the reader their data is wrong. A defect that crashes the program is a `> [!WARNING]` too, because unsaved work is lost. So is a defect whose error hides a silent part, such as a procedure that runs twice before the error is raised. A defect the reader cannot miss and that loses nothing, such as an error raised or a statement the compiler refuses, is a `> [!NOTE]`. Either callout names the build it applies to, in its label. Once a fixed build is out, remove the callout and describe the correct behaviour with no mention of the defect: the documentation is not a record of past defects.
 
 Where twinBASIC and VB6 behave differently, say what VB6 does. Check it in VB6 --- [`vb6run.mjs`](Tools-Defects#vb6run) builds and runs a sample there --- rather than writing it from memory. Where twinBASIC's behaviour is the intended one, the VB6 behaviour goes in a `> [!NOTE]`. Inside a defect's `> [!WARNING]` it is one sentence, such as "VB6 raises error 6, *Overflow*."
 
 Use one callout per concern, and only for genuine notes: plain "why this is useful" prose stays a plain paragraph.
 
+### What a callout applies to
+
+A callout that is true of one twinBASIC build, or of one version of a package, says so in its label: the rest of the `[!TYPE]` line. The page shows each item of the label as a tag after the callout's title.
+
+```md
+> [!WARNING] BETA 1005
+> **DateAdd** with the "m", "q" or "yyyy" interval does not stop at the end of a shorter month.
+```
+
+- `BETA 1005` --- true of that build, the usual label of a defect.
+- `since BETA 984` --- true from that build on.
+- `1.0.0.4` --- true of that version of the package whose section the page is in, written with all four parts.
+- `1.6.151.1, BETA 1005` --- both, separated by a comma.
+- `timeless` --- true of every build and every version: a fact of Windows or COM, behaviour the package exists to reproduce, such as the Scripting Runtime's for a replacement of it, or a design decision the package's sources state. It stands alone, and the page shows no tag for it.
+
+The text then starts with the fact itself, not with "In twinBASIC BETA 1005, ..." or "In version 1.0.0.4, ...". If only part of a callout depends on the build, split it into two callouts. In a contributed package's section every callout has a label: the section's version for what the package does, `BETA <n>` for a fact of twinBASIC alone, or `timeless`. The build fails on a callout there without one, on any other label, and on a package version other than the one the section documents, its landing page's `indexed_from`. So when a section moves to a new version of its package, each callout labelled with the old one is checked again before the build passes. [`twin-index analyze`](Tools-Build#twin-index) lists those callouts, and after a new twinBASIC build, the callouts labelled with an older one.
+
+A page states what the product does, never what the documentation's own checking could or could not do. "The samples harness cannot capture a console" is a fact about this repository's tools, not about the package, and has no place in a published page. A claim nobody has been able to check is written as the source supports it, or left out.
+
+### Callouts in a contributed package's section
+
+Every `> [!NOTE]` and `> [!WARNING]` in a contributed package's section is backed by test cases in the package's test project, `test/package-tests/<Package>/`, and names them in an HTML comment on the line above it:
+
+    <!-- test: FilesTests.Item_MissingName, FilesTests.Item_MissingIndex -->
+    > [!NOTE]
+
+An item is a `Fixture.Sub` test case, `compile <Name>` for a compile case, `probe <id>` for a scenario of the package's `probe/` harness, or `none -- <reason>` for a callout no program can check. A case checks what is correct, so a defect of the package is a failing case.
+
+A callout is for a real difference or limit. A statement that only describes how the package works stays prose, and its cases are tied to it by a region: the same marker on a line of its own above the prose, and `<!-- /test -->` after it.
+
+```md
+<!-- test: SearchGivesUpTests.Execute_CatastrophicPatternKeepsMatchesFound -->
+A search that backtracks without end gives up instead of hanging.
+<!-- /test -->
+```
+
+A region may hold paragraphs, lists, tables and samples, and regions do not nest. The folder's README says how to write a case, and [`check_package_tests.mjs`](Tools-Toolchain-Tests#check-package-tests), in `test.bat`, fails a callout with neither a marker nor a region, a region left open, and a case no marker names. [`package-tests.bat`](Tools#package-testsbat) runs the cases. The section's landing page ends with a short **Test cases** section that links to the project the build publishes, `<Package>-tests.twinproj`.

 - **Audit mode**, for a section with no `indexed_from`, and when update mode has nothing to compare with: no committed snapshot, one in an older format, or one of another version, each with a warning. Every public symbol is matched by name with the `title:` of the pages in the section, and those with no page are to create.
 
+**The callouts to check again.** A callout's label says which build of twinBASIC or which version of its package it is true of (see [What a callout applies to](Authoring#what-a-callout-applies-to)). When the store holds a version of a package other than its section's `indexed_from`, the report lists each callout of the section labelled with another version, as a `recheck_callout` task: the build refuses the section's new `indexed_from` until each is checked and its label moved, or the callout removed. An `analyze` with no `--package`, `--packages` or `--all` also lists the callouts of the whole documentation labelled `BETA <n>` below the build the store's built-in packages were read from, and writes them to `indexer/.packages/callouts.json`. A `since BETA <n>` label is never listed, and neither is `timeless`: both stay true.

 `analyze` exits 0 whenever it writes its report, whatever the report lists: the list is the product, not a failure.
 
 **What `draft` places.** `draft` reads the last report and, for each package in it (or each one `--package` or `--packages` names), writes the plan `indexer/.packages/draft/<package>.json`. Each entry names the page file to write or change, the title of its parent, and its permalink, all taken from what most of the section's pages do: a new type goes in the folder the section keeps that kind of type in (an `Enumerations/` folder, or beside the classes), as a folder with an `index.md` or as one page as those types are; a type that another type returns, such as a collection's item, goes in that type's folder when the folder already holds a type; and a new member gets a page of its own or goes on its type's page, as that type's other members do. A permalink is filled in only when every page of the section has the permalink its folders give it, which is so for every section except VBA's; otherwise it is left to follow the sibling pages. Each entry also names a page of the same kind in the section to follow, and the source file that declares the symbol. A package with no section gets one in its group's folder, with a landing page titled and placed like those of the group's other sections. A symbol no page can be found for, such as a member of a type that has no page, is listed as unplaced. A symbol the build no longer declares is listed with the page that documents it. The pages are also split into batches, one file each, for whoever writes them in parallel.

 3. Set `indexed_from` on each section to the new build's tag (`beta-x-0997` is BETA 997), and commit the pages, the new `indexed_from`, the new snapshots and `builder/package-api.json` together. A snapshot committed on its own, or an `indexed_from` that is not the snapshot's `version`, sends the next `analyze` into audit mode.
 
 **After a change to the scanner or the model.** The code that writes `api.json` is `scripts/lib/twin-api.mjs`, `scripts/lib/twin-declarations.mjs`, `indexer/lib/api-model.mjs` and `indexer/lib/vb6-preprocess.mjs`. A change to any of them, the `format` number of `api.json` included, can change what the same sources index to. The next `sync` indexes every package again, and the committed snapshots have to be written again from the build they record, with `sync --ide` naming that build's install, in the same commit as the change. Otherwise `analyze` compares the output of the new code with that of the old and reports the difference as changes to the API. `--release` cannot do this: it downloads only the latest release.

When the target is not `win32`, or the IDE remembered another, the report starts with a `target:` line. |
 | `--timeout <secs>` | Give up waiting for the compile to settle. Default 180. |
 | `--build` | After a compile with no errors, build the project as the toolbar's Build button does, and print `built: <file>` after the summary line. The given file is never changed (see below). |
 | `--llvm` | `--build` with the project's compiler options set to `+llvm`. Refused, with exit 2, on a Community or Personal licence, which would silently build with the default compiler. A plain `--build` is the control for an `--llvm` run. |
 | `--json` | Emit one JSON object instead of lines of text: the target, counts, diagnostic rows, the text of any alert the IDE opened (dismissed so the compile can go on), `built` (the file a build wrote, or null) and `buildLog`. |
-| `--keep` | Leave the IDE running and print its pid as `ide-pid: <n>`, then the `taskkill` command that ends it and every process it started, for cmd and PowerShell and for Git Bash (`//PID`). The IDE's registry entries for the project are left as they are, since the IDE is still writing them. |

 **A compile does not generate code, and a build does.** LLVM code generation can refuse a construct the compiler's front end accepts ("a feature used in your code is not yet supported with the LLVM compiler"), so a clean compile says nothing about an LLVM build. `--build` and `--llvm` press Build after the compile and read the build log.

Each package the reference documents under `docs/Reference/Contributed/` has one in `test/package-tests/<Package>/`: `[TestCase]` Subs of `[TestFixture]` modules that check every claim the NOTEs and WARNINGs of its section make, a generated `RunAll` module, and `expect.json`. The README in that folder says how a case is written. Each case checks what is correct, so a defect of the package is a failing case, and `expect.json` records how each case fails, or that it never returns, on the version the section documents.
+
+For each package and architecture (both by default), the tool stages the project with the package embedded, downloading it from TWINSERV into `%TEMP%\tb-twinserv` the first time, and runs it with [`tbrun --tests`](Tools-Compiler#tbrun). Each case is then judged:
+
+- **documented** --- as `expect.json` says;
+- **fixed** --- `expect.json` says it fails or never returns, and it passes: the page's callout and the entry go;
+- **changed** --- anything else: a claim of the page is no longer true, or the case is wrong.
+
+A case that never returns stops the compiler. The tool catches it, runs the cases after it again in a new IDE, and from then on, once `expect.json` says so, runs it alone with `--hang-timeout`. `--update` writes `expect.json` from the run, for the architectures run. The run also writes `RunAll.twin` again whenever the cases or `expect.json` change; [`check_package_tests.mjs`](Tools-Toolchain-Tests#check-package-tests) fails while it is out of date.
+
+The build publishes each project as `<Package>-tests.twinproj` beside the package's section, and the section's landing page links to it. It carries none of the package's code: it references the package as a [linked package](../../Features/Packages/Linked), which the IDE loads from `%APPDATA%\twinBASIC\packages`. With the package's file there, the project's `Sub Main` runs every case and prints `PASS`, `FAIL` or `SKIP` for each in the DEBUG CONSOLE.
+
+It is outside every gate and CI: it needs Windows and a twinBASIC install. [`package-tests.bat`](Tools#package-testsbat) runs it.
+
+Exit codes: **0** every case did what `expect.json` says; **1** a case was fixed or changed; **2** a refused command line, a package with no test project, or the harness failed.

 ## Resources
 
 A resource is a file that the build embeds in the program, such as an icon, a bitmap, a manifest or a table of strings. The resources are in the `Resources` folder, in a subfolder named for the resource's type. A new Standard EXE project has `Resources/ICON/twinBASIC.ico`. A project that uses Visual Styles also has a `MANIFEST` folder. The `STRING` and `MESSAGETABLE` folders appear when you add those resources.

 **StringValidation** is a standard module of five public functions. [**StringContains**](StringContains), [**StringContainsAny**](StringContainsAny), [**StringMatchesAny**](StringMatchesAny) and [**StringStartsWith**](StringStartsWith) return a **Boolean** about the text of a string, and [**CopyCapitalisation**](CopyCapitalisation) returns a string in the letter case of another. The formatter calls them to look for backslashes and escape sequences, to test whether a format string begins with `@` and to follow the case of an identifier. A project that references the package can call them too, by name or as `StringValidation.StringContains`.
 
-> [!NOTE]
-> The package declares the module with `Option Private Module`, which marks it as internal to the package. A project that references the package can still call its functions (checked on BETA 1005).

A BOM is not written again, and none is written to an existing file that is empty. The line ending for **WriteLine** is the one the first 64 KB of the file use, and *writeModeLineEnding* is used only for an empty file, a file without a line ending and a file with mixed ones.

 The **tbFileSysTools** contributed package, listed in the Available Packages dialog as *File System Tools - Modern Replacement for FSO*, reads and changes files, folders and drives, as the **FileSystemObject** of the Scripting Runtime does, and is written in twinBASIC. It reads and writes text files in any Windows code page, with detection of the encoding and handling of byte-order marks (BOMs), detects and converts line endings, streams files of any size, and works with paths longer than 260 characters.

 - Detection: [**GetFileEncoding**](FileSystemTools#getfileencoding) and [**GetFileLineEnding**](FileSystemTools#getfilelineending).
 - Searching and locks: [**FindInTextFiles**](FileSystemTools#findintextfiles), [**FileContainsText**](FileSystemTools#filecontainstext) and [**IsFileLocked**](FileSystemTools#isfilelocked).
-- Paths and directories: [**CleanFileName**](FileSystemTools#cleanfilename), [**GetRelativePath**](FileSystemTools#getrelativepath), [**GetFilePaths**](FileSystemTools#getfilepaths), [**GetFileType**](FileSystemTools#getfiletype), [**GetCurrentDir**](FileSystemTools#getcurrentdir), [**SetCurrentDir**](FileSystemTools#setcurrentdir) and [**Rename**](FileSystemTools#rename).
+- Paths and directories: [**CleanFileName**](FileSystemTools#cleanfilename), [**GetRelativePath**](FileSystemTools#getrelativepath), [**GetFilePaths**](FileSystemTools#getfilepaths), [**GetFileType**](FileSystemTools#getfiletype), [**GetSpecialFolderPath**](FileSystemTools#getspecialfolderpath), [**GetCurrentDir**](FileSystemTools#getcurrentdir), [**SetCurrentDir**](FileSystemTools#setcurrentdir) and [**Rename**](FileSystemTools#rename).
 - On [**File**](File): **ContainsText**, **Encoding**, **ExtensionName**, **HasAttribute**, **IsLocked**, **LineEnding**, **Normalize**, **Refresh**, **Rename**, **SetAttribute**, **ToStream**, **ToString** and **Version**. On [**Folder**](Folder): **HasAttribute**, **Refresh**, **Rename** and **SetAttribute**. On [**Drive**](Drive): **SerialNumberHex** and **UnsignedSerialNumber**. On [**TextStream**](TextStream): **Encoding**, **Flush** and **IsStreaming**.
 - [**Files**](Files), [**Folders**](Folders) and [**Drives**](Drives) return an item by position as well as by name.
 - Enumerations for the encodings, line endings and 25 special folders.
 
 **Members with more arguments.** [**CreateFolder**](FileSystemTools#createfolder) can create the folders above the new one. [**DeleteFile**](FileSystemTools#deletefile) and [**DeleteFolder**](FileSystemTools#deletefolder) can ignore a missing target. [**GetAbsolutePathName**](FileSystemTools#getabsolutepathname) takes a base directory. [**GetTempName**](FileSystemTools#gettempname) takes a prefix, an extension and a folder to check.
 
-**Missing members.** One: the **Add** method of the **Folders** collection, which creates a folder. [**CreateFolder**](FileSystemTools#createfolder) does that. Every other member of the Scripting Runtime's **FileSystemObject**, **File**, **Folder**, **Drive** and **TextStream** is here, and so are **Count**, **Item** and the enumerator of the three collections. **Drives** of the class [**FileSystemObject**](FileSystemObject#drives) is a function, called with or without parentheses.
+**Missing members.** None. Every member of the Scripting Runtime's **FileSystemObject**, **File**, **Folder**, **Drive** and **TextStream** is here, and so are **Count**, **Item** and the enumerator of the three collections, and the **Add** method of **Folders**. **Drives** of the class [**FileSystemObject**](FileSystemObject#drives) is a function, called with or without parentheses.
 
 **Arguments that mean something else.** The Scripting Runtime selects the encoding of a text file with a **Boolean** (*Unicode*, in **CreateTextFile**) or a **Tristate** (*Format*, in **OpenTextFile** and **OpenAsTextStream**). Here the argument is a [**TextEncoding**](FileSystemTools#textencoding). Code that passes **True** or **TristateTrue**, which is -1, gets **encAutoDetect**, and for writing that is UTF-8, not UTF-16. The defaults also differ: a text file is written in UTF-8 without a BOM, where the Scripting Runtime writes ANSI, and a file opened for reading has its encoding detected, where the Scripting Runtime reads ANSI.
 
 **Results that differ.**
 
-- [**GetSpecialFolder**](FileSystemTools#getspecialfolder) returns the path as a **String**, where the Scripting Runtime returns a **Folder**. It accepts 25 folders, and not only the Windows, System and Temporary folders.
+- [**GetSpecialFolder**](FileSystemTools#getspecialfolder) accepts 25 folders, and not only the Windows, System and Temporary folders. Like the Scripting Runtime's it returns a **Folder**; [**GetSpecialFolderPath**](FileSystemTools#getspecialfolderpath) returns the path as a **String**, for a folder that may not exist.
 - [**FileAttribute**](FileSystemTools#fileattribute) has no *Volume* (8) and no *Alias* (1024). The label of a volume is [**Drive.VolumeName**](Drive#volumename), and an alias is **faReparsePoint**. [**File**](File#setattribute) and [**Folder**](Folder#setattribute) add **SetAttribute** and **HasAttribute**, which change and test one attribute.
 - [**Folder.Size**](Folder#size), [**CopyFolder**](FileSystemTools#copyfolder), [**DeleteFolder**](FileSystemTools#deletefolder) and [**GetFilePaths**](FileSystemTools#getfilepaths) with *recursive* do not enter directory junctions and symbolic links. The Scripting Runtime does, and counts the target of a link twice when it is in the same tree: 2,500 bytes there for a folder that holds 1,500. Its **CopyFolder** copies the files of the target into the copy, and its **DeleteFolder** deletes them.
 - [**BuildPath**](FileSystemTools#buildpath) and [**GetParentFolderName**](FileSystemTools#getparentfoldername) turn `/` into `\`. `BuildPath("C:\a", "b/c")` returns `C:\a\b\c` and the Scripting Runtime `C:\a\b/c`; `GetParentFolderName("C:/a/b.txt")` returns `C:\a` and the Scripting Runtime `C:/a`.
 - [**GetAbsolutePathName**](FileSystemTools#getabsolutepathname) raises error 52 for an empty string, where the Scripting Runtime returns the current directory.
 - [**CopyFile**](FileSystemTools#copyfile), [**CopyFolder**](FileSystemTools#copyfolder), [**MoveFile**](FileSystemTools#movefile) and [**MoveFolder**](FileSystemTools#movefolder) put the source inside an existing destination folder, whether or not the destination ends in a backslash. The Scripting Runtime does so only with a backslash. Without one it raises error 70 for **CopyFile**, 58 for **MoveFile** and **MoveFolder**, and **CopyFolder** copies the contents of the source straight into the folder.
 - [**MoveFile**](FileSystemTools#movefile) moves a folder when *source* names one. The Scripting Runtime raises error 53.
-- [**DeleteFolder**](FileSystemTools#deletefolder) of a folder that holds a read-only file raises error 75 without *force*; the Scripting Runtime raises 70.
-- [**GetFileVersion**](FileSystemTools#getfileversion) returns an empty string for a file that does not exist. The Scripting Runtime raises an error.
+- [**GetFileVersion**](FileSystemTools#getfileversion) raises error 53 for a file that does not exist. The Scripting Runtime raises the Windows code `0x80070002` as the error number.
 - At the end of a stream, [**ReadAll**](TextStream#readall) returns an empty string and [**Skip**](TextStream#skip) does nothing, where the Scripting Runtime raises error 62. A closed stream raises 52 here and 91 there.
-- [**Files.Item**](Files#item), [**Folders.Item**](Folders#item) and [**Drives.Item**](Drives#item) take a position as well as a name. A name or a position that is not in the collection raises error 5; the Scripting Runtime raises 53, 76 and 68 for a name that is not in the three.
+- [**Files.Item**](Files#item), [**Folders.Item**](Folders#item) and [**Drives.Item**](Drives#item) take a position as well as a name. A name or a position that is not in the collection raises 53, 76 and 68, the numbers that the Scripting Runtime raises for a name that is not in the three; for a position it raises error 5.
 - [**GetTempName**](FileSystemTools#gettempname) returns eight random letters and digits and `.tmp`. The Scripting Runtime returns `rad` and five hexadecimal digits.
 - A path longer than 260 characters works in most procedures. The Scripting Runtime does not accept it: **FileExists** and **FolderExists** return **False** for it, **GetFile** raises error 53 and **OpenTextFile** raises 76.
-- [**StringToTextFile**](FileSystemTools#stringtotextfile), [**ArrayToTextFile**](FileSystemTools#arraytotextfile) and [**WriteStream**](FileSystemTools#writestream) replace a read-only file without an error. [**CreateTextFile**](FileSystemTools#createtextfile) raises error 70 for it, as the Scripting Runtime's does.
 
-**The same.** For these failures the two raise the same error numbers: a missing file (53) or folder (76) from **GetFile**, **GetFolder**, **CopyFile**, **DeleteFile**, **DeleteFolder** and **OpenTextFile**; an existing folder or destination (58) from **CreateFolder**, **CopyFile**, **MoveFile** and **CreateTextFile**; a missing parent folder (76) from **CreateFolder**; a drive that does not exist (68) and a path that is longer than a drive (5) from **GetDrive**; a read-only destination or file (70) from **CopyFile**, **DeleteFile** and **CreateTextFile**; an unreadable folder (70) from **Files**, **SubFolders** and **Size**; the wrong direction of a stream (54) and a read at the end (62) from **TextStream**. Both match a pattern against the 8.3 name of a file in **CopyFile**, **DeleteFile** and **MoveFile**, and both accept `C:` as the item of **Drives**.

+Returns whether the last search of this object gave up before it finished.
+
+Syntax: *object*.**SearchAborted**
+
+*object*
+: *required* An object expression that evaluates to a **RegExp**.
+
+Returns a **Boolean**: **True** when the most recent call of [**Test**](Test), [**Execute**](Execute), [**Replace**](Replace) or [**Split**](Split) on *object* stopped because its search ran out of steps, **False** otherwise. The property is read-only. It is **False** for an object that has not searched yet.
+
+## Remarks
+
+A search is given a budget of steps, where a step is one operation of the compiled pattern. A pattern that backtracks without end, such as `(a+)+b` on a string of thirty `a`, needs twice as many steps for each `a` it is given, and the budget is what stops it. VBScript's **RegExp** has no such limit and for that string does not return in any reasonable time.
+
+When the budget runs out, the search stops and nothing is raised. Whatever was found before is returned, and the result can be short or empty: [**Test**](Test) returns **False**, [**Execute**](Execute) returns the matches found before the search stopped, [**Replace**](Replace) returns *sourceString* with only those matches replaced, and [**Split**](Split) splits only at them. A program that cannot tell this from a string without a match reads **SearchAborted** after the call.
+
+The budget is 5,000 steps for each character of the string, at least 1,000,000 and at most 50,000,000. It is not a property of the object, and a program cannot change it. It applies to the search for one match, so with [**Global**](Global) set to **True** each match has a budget of its own, and the first search that runs out ends the call. A simple pattern needs about three steps for each character it matches, so a long match is not affected: `a*` on a string of 1,000,000 `a` returns all of it in about half a second.
+
+Each call of **Test**, **Execute**, **Replace** or **Split** sets the value again: a call that finishes its search sets it to **False**, and so does a call that raises an error because the pattern is not valid, because no search was made. The value belongs to the object. A search on another **RegExp** does not change it, and a new object returns **False**.
+
+<!-- test: SearchAbortedTests.SearchAborted_DigitsWithoutXFinishAt2000, SearchAbortedTests.SearchAborted_DigitsWithoutXFinishAt5000 -->
+> [!NOTE] 1.8.0.0
+> A pattern that is not catastrophic can also run out of steps, if it tries again from each start position and the string is long. `\d+x` on a string of 5,000 digits and no `x` takes a few seconds and then gives up, with the same result as for a string that has no match, and **SearchAborted** returns **True**. A string of 2,000 digits finishes in a second or two and returns **False**.
+
+## Example
+
+This example searches a string of thirty `a` for `(a+)+b`, which cannot match and takes a very long time to prove it. The search gives up after about a fifth of a second, and **SearchAborted** says that the **False** from **Test** is not an answer. A search of a string that has no `b`, where the pattern is not catastrophic, finishes.

+Debug.Print re.Test(String(30, "a"))       ' False
+Debug.Print re.SearchAborted               ' False
+```
+
+This example shows that the value is per object, and that a search which gave up still returns the matches found before it.

+**Author:** GCuser99. **Version:** 1.8.0.0. **On GitHub:** [GCuser99/tbRegExp](https://github.com/GCuser99/tbRegExp), in the folder *Package*.
 
 The **tbRegExp** contributed package provides regular expressions for twinBASIC projects, as a replacement for the **RegExp** object of VBScript. It follows the same object model. A [**RegExp**](RegExp/) is given a pattern and options, its [**Execute**](RegExp/Execute) method returns a [**MatchCollection**](MatchCollection/) of [**Match**](Match/) objects, and each **Match** holds the text captured by the groups of the pattern as a [**SubMatches**](SubMatches/) object. Positions are zero-based, as in VBScript.
 
-> [!WARNING]
-> A match can be at most about 3,300 characters long. A longer one is reported cut short, later in the string, or not at all, and no error is raised. The engine gives up a search from one starting position after 10,000 steps, where a step is one operation of the compiled pattern, and then starts again one character later. The limit is fixed inside the package, and a program cannot change it. A pattern that repeats one character, such as `a*`, `.*` or `[^,]*`, takes three steps for each character it matches, so its longest match is 3,331 characters, and a pattern with more to do for each character has a shorter longest match. On a string of 5,000 `a`, `a*` finds a match that starts at position 1669 and is 3,331 characters long, where VBScript's **RegExp** finds the whole string from position 0, and `^.*$` finds no match at all, so [**Test**](RegExp/Test) returns **False**. Each starting position that fails costs up to 10,000 steps, so a search over a long run is slow as well: `a*` over a run of 9,500 characters takes several seconds, and returns a match of 3,331 characters from position 6169. This is how version 1.7.0.0 behaves.

 The matching is done by the [vba-regex](https://github.com/sihlfall/vba-regex) engine of sihlfall, which the package includes as a private module, **StaticRegex**.
 
-Beyond VBScript's object, **RegExp** has the [**DotAll**](RegExp/DotAll) and [**Flags**](RegExp/Flags) options, the [**Split**](RegExp/Split) method, and [**IsValid**](RegExp/IsValid), [**LastError**](RegExp/LastError) and [**LastErrorNumber**](RegExp/LastErrorNumber), which report an invalid pattern before it is used. [**Replace**](RegExp/Replace) reads a `$` in the replacement string as VBScript does, and adds `$<name>` for a named group.

Every search has a budget of steps, which a program cannot change, and when it runs out the search stops and raises no error. Its result is then short or empty, and a program that has to tell it from a true result reads [**SearchAborted**](RegExp/SearchAborted) after the call.

+' Expect: the checks every test case of the twinBASIC documentation's package tests makes.
+' Part of each test project; https://docs.twinbasic.com. MIT licence.
+'
+' A case is a [TestCase] Sub of a [TestFixture] Module. It starts with Expect.Begin, checks with
+' Expect.AreEqual, Expect.IsTrue, Expect.IsFalse and Expect.Fail, and ends with Expect.Done. Each
+' check states what is correct, so a case that fails names a defect of the package. A failed check
+' does not stop the case: Expect.Done reports every failed check of the case at once.
+'
+' Run the project (Sub Main in the module RunAll) to run every case: each one prints PASS, FAIL or
+' SKIP in the DEBUG CONSOLE. A test runner that runs one case at a time sees a failed case as a
+' failed assertion, which the case's own On Error statement cannot hide.

+# Package test projects
+
+Each contributed package the reference documents (`docs/Reference/Contributed/<Package>/`) has a
+test project here: twinBASIC test cases for every claim its NOTEs and WARNINGs make. The build
+publishes each project as `<Package>-tests.twinproj` beside the package's section, for a reader or
+the package's author to open, add the package to, and run.
+
+```
+test/package-tests/
+  Expect.twin              the checks every case makes; part of every project
+  <Package>/
+    Sources/
+      <Fixture>.twin       [TestFixture] modules of [TestCase] Subs
+      RunAll.twin          generated: Sub Main runs every case
+    expect.json            how each case fails on the documented version
+    probe/                 optional: a harness for what only a built program shows
+```
+
+A project has no `Settings` of its own: it takes the package's sample template's,
+`test/example-projects/contributed-<Package>/Settings`, which names the version the section
+documents (`lib/package-tests.mjs`). So a section moved to a new version moves its test project
+with it.
+
+## Writing a case
+
+A case is a parameterless `[TestCase]` Sub of a `[TestFixture]` Module. It starts with
+`Expect.Begin`, ends with `Expect.Done`, and checks with `Expect.AreEqual expected, actual, what`,
+`Expect.IsTrue`, `Expect.IsFalse` and `Expect.Fail what`. A failed check does not stop the case;
+`Expect.Done` reports every failed check at once.
+
+```vb
+[TestFixture]
+Module FilesTests
+
+    [TestCase]
+    Public Sub Item_MissingName()
+        Expect.Begin
+        Dim fso As New FileSystemObject
+        On Error Resume Next
+        Dim f As File
+        Set f = fso.GetFolder(Environ$("TEMP")).Files("no such file.txt")
+        Expect.AreEqual 53, Err.Number, "Files.Item of a missing name raises"
+        Expect.Done
+    End Sub
+
+End Module
+```
+
+- **A case checks what is correct**, not what the package does: a defect is a failing case, so the
+  project tells the package's author what to fix. What *correct* is comes from the package's own
+  description, the object it stands in for (VBScript's **RegExp**, the Scripting Runtime's
+  **FileSystemObject**) or the standard it implements.
+- **Name a case for the behaviour**, `<Member>_<What>`, one behaviour per case, so a failure names
+  one defect. A callout that makes three claims gets three cases.
+- **A case is self-contained**: it creates what it needs and removes it. Files go only under
+  `%TEMP%\tbdocs-package-tests\<Package>\`; nothing in the registry, a special folder or the
+  user's profile changes. No `MsgBox`, `InputBox`, `End`, no window left open, and nothing that
+  starts a browser or explorer (`ShellExecute` or `OpenFile` with an empty path does).
+- **The checks' `what` is read by the author**: say what was done, so that
+  `Files.Item of a missing name raises: expected 53, got 5` is a bug report.
+- A claim about what does not compile is a **compile case**: a line ending in
+  `' CASE <Name>: TB5001` (or `: error`, `: none`), as `scripts/lib/tb-tests.mjs` describes.
+- A claim that needs a dialog operated or a form shown goes in the package's `probe/` harness, as
+  TBMANLIB_Dialog's and xCalendar's do.
+
+## Tying the pages to the cases
+
+Every `> [!NOTE]` and `> [!WARNING]` of the section's pages has a marker on the line above it:
+
+```md
+<!-- test: FilesTests.Item_MissingName, FilesTests.Item_MissingIndex -->
+> [!NOTE]
+```
+
+A NOTE or WARNING is for a real difference or limit: a defect, a difference from the object the
+package replaces, a limit a program can meet. A statement that only describes how the package
+works stays prose, and the cases that check it are tied to it by a **region**: the same marker on
+a line of its own above the prose, and `<!-- /test -->` after it. A region can hold paragraphs,
+lists, tables and samples; regions do not nest, and a callout inside one needs no marker of its
+own. Both are HTML comments, invisible on the page.
+
+```md
+<!-- test: SearchGivesUpTests.Execute_CatastrophicPatternKeepsMatchesFound -->
+A search that backtracks without end, such as `(a+)+b` on thirty `a`, gives up instead of hanging.
+<!-- /test -->
+```
+
+An item is `Fixture.Sub`, `compile <Name>`, `probe <id>` (a scenario of `probe/`), or
+`none -- <reason>` for a callout no program can check (a statement about the IDE, a licence).
+`node scripts/check_package_tests.mjs`, in `test.bat`, fails when a callout has neither a marker
+nor a region around it, a region is not closed or opens inside another, an item names nothing, a
+case is named by no marker, a case does not start with `Expect.Begin` and end with `Expect.Done`,
+`expect.json` is for another version, or `RunAll.twin` is out of date. A section whose project is
+not written yet is in the script's `PENDING` set; the package's project takes it out.
+
+## Running
+
+```
+package-tests.bat tbregexp                  both architectures, judged against expect.json
+package-tests.bat tbRegExp --arch win32
+package-tests.bat tbRegExp --update         write expect.json from the run
+package-tests.bat --all-packages            every project, several minutes a package
+```
+
+A package is named in any case. With no package named and no `--all-packages`, the run is
+refused and lists the packages that have a test project.
+
+`scripts/package_tests.mjs` stages the project with the package embedded (downloaded from TWINSERV
+into `%TEMP%\tb-twinserv` once) and runs it with `tbrun --tests`, which runs each case in the
+compiler's test mode, so a crash or an access violation ends only its case. Each case is then:
+
+- **documented**: as `expect.json` says: it passes, fails with the recorded report, or never
+  returns;
+- **fixed**: `expect.json` says it fails or never returns, and it passes. The page's callout goes
+  (the documentation is not a record of past defects), and so does the entry;
+- **changed**: anything else. A claim of the page is no longer true, or the case is wrong.
+
+A case that never returns stops the compiler, so it is caught, recorded as `{ "hangs": true }` by
+`--update`, run alone from then on, and skipped by `RunAll`. The run writes `RunAll.twin` again
+whenever the cases or `expect.json` change.
+
+`expect.json`:
+
+```json
+{
+  "version": "1.9.0.0",
+  "cases": {
+    "FilesTests.Item_MissingName": { "fails": "1 of 1 checks failed: Files.Item of a missing name raises: expected 53, got 5" },
+    "ListTests.ToString_Empty": { "hangs": true },
+    "SubClassTests.Hook": { "win32": "pass", "win64": { "fails": "..." } }
+  }
+}
+```
+
+A case not named passes on both architectures. Write it with `--update`, then read every entry: an
+entry is a claim that the package is defective, and each one must match a callout.
+
+## In the IDE
+
+`RunAll`'s `Sub Main` is the project's startup object: run the project and each case prints
+`PASS`, `FAIL` or `SKIP` in the DEBUG CONSOLE, then a count. That is how a reader or the package's
+author runs the published project. The download carries none of the package's code: it references
+the package as a *linked* package, which the IDE loads from the package's `.twinpack` in
+`%APPDATA%\twinBASIC\packages` (found by its project id) once the compiler has started. So the
+reader puts the package's file there, of the version the section documents, or adds the package
+from Available Packages with Embedded cleared, and restarts the compiler. The IDE takes the
+version from that file, not from the reference, and nothing in the IDE downloads a missing package
+by itself (BETA 1005).

-// Unit tests for scripts/lib/tb-ports.mjs, which claims the DevTools ports a
-// run's IDEs use so that two runs never share one.
+// Unit tests for what the harness keeps for each DevTools port: the claim
+// (scripts/lib/tb-ports.mjs), which stops two runs sharing a port, and the
+// folders an IDE started on it leaves under %TEMP% (shutdownIde in
+// scripts/lib/tb-ide.mjs).
 //
 // The harness runs that claim ports need a twinBASIC install, so they run only
 // by hand; claiming a port needs none. Four child processes claim at once, from
 // a range where one port is listened on, one holds a stale lock and one a live
 // lock, and their claims are checked against the ports that were free.
 //
+// The folders are tested with no IDE: the handle names a process id that cannot
+// be a process, so the IDE is already gone when shutdownIde looks at its
+// folders, as it is after waitForExit.
+//
 // Runs with a bare `node --test test/ports.test.mjs`: no tree, no IDE.
