Prepares the 0.4.0 release

[johnnyt]

Prepares the @riddler/predicator 0.4.0 release, by hand from .claude/wurk/release.md (the kit has no npm recipe). A minor, as ruled by the operator, 2026-10-01. This PR does not merge, tag or publish: the conductor merges it, pulls main, creates the annotated tag v0.4.0 at the merge SHA and pushes it; the operator runs npm publish.

Commits

• 78064dd Prepares the 0.4.0 release

The release commit touches exactly the files the release checklist's table names: package.json ("version" 0.3.0 -> 0.4.0 and nothing else), README.md (the install pin ^0.3.0 -> ^0.4.0 and nothing else), CHANGELOG.md (the new section, above 0.3.0's) and the promoted changelog.d/*.md fragments (deleted). changelog.d/ holds only its README.md afterwards.

Premise checks

• origin/main was fe15d4b when this branch was cut; the reference prep is 1ddd46b (the first line of git log --oneline --no-patch -L '/"version"/,+1:package.json').
• npm view @riddler/predicator dist-tags answered { latest: '0.3.0' } before the bump.
• No tag v0.4.0 exists (git rev-parse -q --verify refs/tags/v0.4.0 exits 1, and git ls-remote --tags origin v0.4.0 lists nothing).
• git log --oneline v0.3.0..origin/main, the release's content, 17 commits:

Fragments promoted

In fragment-name order, seven: pts-0o0p, pts-0zns, pts-ix34, pts-mmls, pts-o0gr, pts-shdy, pts-xmz6. Under Added: pts-0o0p, pts-ix34, pts-mmls, pts-shdy, pts-xmz6 (two bullets). Under Changed: pts-0zns, pts-o0gr. No fragment carries Deprecated, Removed, Fixed or Security. A script compared every - bullet line of every fragment at fe15d4b against the new section with a whole-line fixed-string match: each was found byte for byte, and the section carries no bullet the fragments do not.

The closed-set question

Asked over every promoted fragment and over the public surface since v0.3.0: git diff v0.3.0..origin/main over src/index.ts, src/tagged.ts, the modules they re-export from (src/compile.ts, src/decompile.ts, src/duration-units.ts, src/errors.ts, src/ast.ts), and test/export-surface.json (the export-surface list the test pins).

Kind	What	Where	Effect on the version
Added public name	compileProgram, compileProgramWithPositions, compileProgramWithSpans	main entry (src/index.ts, from src/compile.ts)	addition
Added public name	durationToMilliseconds	main entry (src/index.ts, from src/duration-units.ts)	addition
Added public name	DecompileResult (the type decompile already answered, now exported by name; shape unchanged)	main entry (src/index.ts, from src/decompile.ts)	addition
Added public name	executeTagged	./tagged (src/tagged.ts)	addition
New members of a closed union a host matches on	unexpected_else, unassignable_location, expected_open_brace	ParseReason (src/errors.ts)	a minor on 0.x; a host with an exhaustive match adds the three arms, as the promoted bullet says
New optional field	details?: { readonly root: string } on EvaluationError, set only on the protected_root refusal; the constructor takes it as an optional fourth argument	src/errors.ts	additive; every other refusal leaves details absent
Changed answer	execute and executeValue compile a source string as a statement program (ruled by the operator, 2026-10-01)	src/index.ts	a host-visible answer change, named in the Changed bullet; no name removed or renamed
Changed answer	a duration component past the largest safe integer is refused by ::duration and parseDuration with the existing invalid_duration_format	src/cast.ts, src/duration-units.ts	a host-visible answer change, no new union member
Removed or renamed public name	none	the export-surface list at v0.3.0 against origin/main adds six names (DecompileResult, the three compileProgram names, durationToMilliseconds, executeTagged) and drops none on . or ./tagged (its one removed diff line is evaluateTagged gaining a trailing comma); the two export lines src/index.ts drops are replaced by wider statements that still name every former name	would hold the prep for the version word; it does not arise

So every change is a minor on 0.x, consistent with 0.4.0. The statement node types added to src/ast.ts are not exported (the public Ast stays the opaque branded type), and the located program results and executeTagged's result are unexported aliases, so a host names them structurally or through ReturnType, as it named decompile's result before DecompileResult.

The publish guard on the pack path

npm pack --dry-run (no registry write; no tarball written) ran prepack, the publish guard: it removed the output directory, rebuilt, and passed all three of its properties, ending publish-guard: the output was built from this tree and is packable, then listed 49 files for @riddler/predicator@0.4.0. The full output, with the worktree path replaced by <worktree>:

The promoted section

## [0.4.0] 2026-10-01

A minor release. The statement grammar compiles from source: `compileProgram`,
`compileProgramWithPositions` and `compileProgramWithSpans` are new, and
`ParseReason` gains the three refusals only they answer. `execute` and
`executeValue` compile a source string as a statement program, as the
reference's do, so a source the expression grammar refused may now run, a
source either grammar refuses may answer the program grammar's refusal, and
`executeValue` given an expression's source now answers that expression's
value. `executeTagged`, `durationToMilliseconds` and the `DecompileResult` type
are new; the protected-root refusal names its root under `details.root`; and a
duration text whose component is past the largest safe integer is refused.

### Added

- A `store` refused for writing into a protected root answers an `EvaluationError` that names that root under `details.root`, so a host reads the root without parsing the message; the reason and the message are unchanged, and every other refusal leaves `details` absent.
- `durationToMilliseconds` answers a duration's length in milliseconds by the reference's weights: a week of seven days, a month of thirty and a year of three hundred and sixty five.
- `executeTagged` on the `./tagged` subpath runs a statement program, from a compiled list or from source text, and answers the context it halted with as the tagged encoding's text on both arms, so `decodeTagged` reads every value back as the one the program bound: a float the program stored stays a float, where `execute`'s plain projection answers the integer.
- `DecompileResult` names the result `decompile` answers - the rendered `source` on the succeeding arm, or the `ParseError` that refused the tree on the failing one - so a host can annotate it by name, as it does `ParseResult` and `CompileResult`, instead of deriving it from the function; the shape is unchanged.
- `compileProgram`, `compileProgramWithPositions` and `compileProgramWithSpans` compile a statement program from source text - assignments, `;`-separated statements, `if`/`else`, `else if` and `while` - to the instruction list `execute` and `executeValue` run, answering the results `compile`, `compileWithPositions` and `compileWithSpans` answer, with one more table on the two located variants: `segmentPositions` or `segmentSpans`, one entry per segment of the location each `store` writes.
- `ParseReason` gains `unexpected_else`, `unassignable_location` and `expected_open_brace`, which only the three program entry points answer; a caller that switches exhaustively on the union adds the three cases.

### Changed

- `execute` and `executeValue` compile a source string as a statement program, as the reference's do, where they compiled it as an expression; `evaluate` still compiles an expression. Two effects follow: a source the expression grammar refused may now run (`execute("x = 1")` binds `x`), and a source either grammar refuses may answer the program grammar's refusal, with a different message or reason (`score 3` is refused as unexpected "after statement" rather than "after expression"). One more follows from the first: `executeValue` given an expression's source now answers that expression's value, where it answered undefined. A caller that wants a source refused unless it is an expression compiles it with `compile` and passes the instruction list.
- A duration text whose component is past the largest safe integer is refused: `::duration` answers undefined and `parseDuration` answers `invalid_duration_format`, where both used to answer a duration whose component was infinite or rounded. The reference, whose integers have no bound, answers such a text with a duration.

Gate

The full gate (mise exec -- pnpm run gate) ran green on the release commit's exact tree (the files staged at the commit are the files the gate ran on, under the same held locks, tree 12ab37e), so the commit was made without a second run. The whole output follows, with the worktree path replaced by <worktree> and temporary-directory prefixes by <tmp>, and terminal color codes removed; nothing else is cut:

Provenance

• The lead paragraph of the 0.4.0 section is the only prose written at release time; it names the program-mode switch's effects only as the pts-0zns fragment states them, and every bullet is carried from its fragment.
• Review tier: contract (a release prep); the conductor dispatches the review.
