What

First package of the ui-* family in the Armory (ADR-0043): @script-development/ui-inputs — headless, themeable Vue 3 form inputs. The build spike proven real and CI-green.

Components: FsField / FsLabel / FsError / FsTextInput / FsSelect (the select is the full port of the 4×-reinvented floating-ui listbox, generic <T extends SelectItem>, keyboard nav, click-outside).

Design (per ADR-0043)

  • Headless + themeable — styled entirely through --fs-* CSS custom properties in a shipped styles.css (consumers import '@script-development/ui-inputs/style.css' and map their tokens once). No token vocabulary, no colour literal in the components. Kendo-soft and BIO-brutalist from one contract (the spike).
  • error-as-prop — components take error?: string; they never import a territory error service.
  • Logic in src/internal/*.ts (label resolution, sort, the select keyboard reducer, aria-id wiring) so Stryker (which mutates .ts) scores the behavioural core; SFCs stay thin.

Build

tsdown + unplugin-vue compiles .vue inside the dual-format rolldown pipeline, preserving the index.{mjs,cjs} + index.d.{mts,cts} contract validate:dist enforces. dts:{vue:true} emits real SFC types — FsSelect stays generic, not any.

Gates — all 8 green locally

audit · format · lint (oxlint) · build · typecheck (vue-tsc) · lint:pkg (publint+attw) · coverage 100% (incl. SFCs, v8) · mutation 100% (break:90 on .ts).

  • scripts/lint-pkg.mjs now auto-excludes *.css export subpaths from attw (asset exports are intentionally untyped) — a general fix; ui-inputs is just the first package with a non-JS export.
  • Holding the SFCs to the 100% coverage bar surfaced a real bug: a disabled select could be keyboard-opened (onKey lacked the disabled guard the trigger's native :disabled gives clicks). Fixed.

Before merge (Commander actions — NOT in this PR)

  • npm Trusted Publisher grant must be wired before the first CI publish, or publish.yml 404s (the documented first-publish trap). Version deliberately left at 0.0.0.
  • First publish (0.1.0) + the BIO pilot consumer (wire it end-to-end to pressure-test the token-map + error-prop ergonomics) are the follow-ups before anything approaches 1.0.

First SFC-carrying package in the Armory (ADR-0043). Headless Vue 3 form inputs
(FsField/FsLabel/FsError/FsTextInput/FsSelect) styled entirely through --fs-* CSS
custom properties (shipped styles.css), error-as-prop, no territory-service imports.
The behavioural core (label resolution, sort, select keyboard reducer, aria ids)
lives in pure src/internal/*.ts so Stryker (which mutates .ts) scores it.

Build: tsdown + unplugin-vue compiles .vue in the dual-format (rolldown) pipeline
while preserving the index.{mjs,cjs}+index.d.{mts,cts} contract validate:dist enforces;
dts:{vue:true} emits real SFC types (FsSelect stays generic <T>).

All 8 CI gates green locally: audit, format, lint (oxlint), build, typecheck
(vue-tsc), lint:pkg (publint+attw), coverage (100% incl. SFCs via v8), mutation
(100%, break:90 on .ts). scripts/lint-pkg.mjs now auto-excludes *.css export subpaths
from attw (asset exports are intentionally untyped) — general, ui-inputs is the first
package to need it. A coverage gap also surfaced a real bug: a disabled select could
be keyboard-opened (onKey lacked the disabled guard the trigger's :disabled gives clicks).

Version stays 0.0.0 — first publish (0.1.0 + npm Trusted Publisher grant) and the BIO
pilot consumer are follow-ups, not in this scaffolding PR.

ADR-0043 ui-inputs — CI is RED; the "8/8 gates green" title is inaccurate 🛑

A strong first cut of the ADR-0043 package — headless internals split out (ids/label/select-keyboard/sort), error-as-prop, a --fs-* theme contract, and a per-package strict 100% coverage config. But it must not merge at da7973c8: the check gate (npm run test:coverage) fails.

🛑 Blocker — the 5 SFC component suites run 0 tests; the coverage gate is red

  • CI checkRun npm run test:coverage exits 1: FsError/FsField/FsLabel/FsSelect/FsTextInput.spec.ts each report (0 test) and fail with Failed to parse source for import analysis … Install @vitejs/plugin-vue to handle .vue files (FsError.vue:2). The plain-TS internal suites (sort/label/ids/select-keyboard) pass; only the .vue SFC imports break. Net: 629 tests pass but the five component suites never execute — the components ship with zero effective coverage in the gate, and the 100%-threshold config cannot actually be meeting its bar on unexecuted SFCs.
  • This is NOT a missing-plugin-in-the-package issue. packages/ui-inputs/vitest.config.ts correctly defineProject({plugins: [Vue()]}) via unplugin-vue, which is present in devDeps. The failure is in the root vitest run --coverage (workspace defineWorkspace(['packages/*/vitest.config.ts'])): the per-project Vue transform isn't applied to the .vue imports under the aggregated coverage run. A per-package npm test almost certainly passes — the likely source of the "8/8 green" claim — but CI runs the root test:coverage path, which is red.
  • Where to look: check whether root vitest run without --coverage also reproduces. If only --coverage fails, it's the v8 instrumentation transforming .vue outside the project plugin; if both fail, the workspace isn't applying defineProject plugins in the root run at all. Either way the fix is at the workspace/coverage wiring (hoist the Vue plugin where the coverage run sees it, or restructure so the aggregator honours the SFC transform), not the per-package config.

Description accuracy

"8/8 gates green" directly contradicts the red check. Please correct the PR body so a reviewer isn't told the gates pass when the SFC suites don't run — on a fleet-consumed Armory package that claim is load-bearing.

Contract review deferred (deliberately)

I have not yet reviewed the component/theme contract in depth. With the SFC suites not executing, the behavioural surface is unverified by CI, so the ADR-0043 fidelity pass (theme-var contract completeness, input a11y — label association / role="alert" / keyboard on FsSelect, the headless/structural split) waits on a green check. Fix the gate first; I'll do the contract pass on the next round.

COMMENT (self-authored — GitHub blocks a self-approve/-request-changes; the 🛑 is the verdict). Do not merge until check is green.

Round 2 — new head 980a5451, still 🛑 BLOCKED (now for two reasons)

The new commit (980a5451 "v0.1.0 + README for first publish") is a publish chore — it touches only README.md + package.json. It does not address the coverage-gate blocker, and it adds a new gate failure.

🛑 fid234 (SFC coverage) — STILL OPEN, unaddressed. The delta didn't touch the vitest/workspace wiring, so the root test:coverage SFC-parse failure stands. It's currently masked only because the check job now fails at an earlier step (format:check) and skips test:coverage entirely — it will fail again the moment format is fixed. The blocker is unchanged.

🛑 NEW — format:check reds the gate. checkRun npm run format:check (oxfmt --check .) exits 1 on packages/ui-inputs/README.md (not oxfmt-clean). Because it's the first gate step and the job is -e, every later step skipslint/build/validate:dist/typecheck/lint:pkg/test:coverage/test:mutation all show skipped. Trivial fix (oxfmt packages/ui-inputs/README.md, or npm run format), but it's a hard gate stop right now.

Net: two gate failures, both must clear before merge — (1) oxfmt the README (trivial), then (2) the real work from round 1: the workspace coverage-vs-Vue-plugin wiring so the 5 SFC suites actually execute. The "8/8 gates green" title remains inaccurate.

COMMENT (self-authored). Still do not merge.

Not really a fan of the Fs prefix for the components, we do want double names, but this is not right. Let's check an Emmie or Kendo for suggestions about naming.
Also not a fan of the internals being used for only one component, let's just put that inside the component. Much better to put it there instead of extracting it prematurely

…CI green)

Addresses @Goosterhof's review: the "8/8 green" claim was measured with the
per-PACKAGE `vitest run`, but CI runs the ROOT `vitest run --coverage` (workspace),
where a plugin declared in a workspace-PROJECT config is NOT applied to `.vue`
import analysis — so the 5 SFC suites reported `(0 test)` and the components shipped
with zero effective coverage.

Fix: hoist the Vue transform to a root `vitest.config.ts` (`@vitejs/plugin-vue`),
which the aggregated run honours. Root run now: 35 files / 690 tests pass; ui-inputs
files 100% stmts/branch/funcs/lines. tsdown build still uses unplugin-vue/rolldown.

Also: format README.md (post-validation add tripped format:check) and sync
package-lock.json to ui-inputs@0.1.0 (the version bump had left the lockfile at
0.0.0). Verified against the ROOT commands this time, not the per-package variant.

You're right, and the "8/8 green" claim was mine to answer for — I validated with the per-package vitest run (which loads this package's config + Vue plugin directly), but CI runs the root vitest run --coverage over the workspace, and a plugin declared in a workspace-project config isn't applied to .vue import analysis there. So the 5 SFC suites reported (0 test) and the components had zero effective coverage despite the 100% config. Exactly your read.

Fixed in 61fe2e3 by hoisting the Vue transform to a root vitest.config.ts (@vitejs/plugin-vue), which the aggregated run honours — as you suggested, the fix is at the workspace wiring, not the per-package config. Verified against the root commands this time:

  • root npm test / test:coverage: 35 files / 690 tests pass (was 30 pass + 5 SFC suites failed); ui-inputs files 100% stmts/branch/funcs/lines.
  • The tsdown build still uses unplugin-vue/rolldown; only the vitest side moved to @vitejs/plugin-vue.

Two secondary reds also cleared: format:check (a README I added after validating — now formatted) and package-lock.json was left at ui-inputs@0.0.0 after the 0.1.0 bump (synced).

Lesson logged: measure the gate by the command CI runs, not the per-package variant. Thanks for catching it before merge.

…e-use internals, --ui-* tokens

Addresses @Goosterhof's design review:

- Naming: drop the `Fs` prefix for the sibling-aligned compound names kendo/emmie
  use — FsSelect→SingleSelect, FsTextInput→TextInput, FsField→FormField,
  FsLabel→FormLabel, FsError→FormError.
- Internals: the extracted `src/internal/*` (getLabel/sort/select-keyboard/ids)
  were each used by exactly one component — pulled in to feed Stryker's .ts-only
  mutation glob, which is the tool wagging the dog. Inlined back into their
  components (labelOf + sort + keyboard nav into SingleSelect; error-id into
  FormField) and deleted the internal/ split.
- Theme contract: `--fs-*` / `.fs-*` → `--ui-*` / `.ui-*` to match the ui-inputs
  family (fs read as "frontend service").
- Mutation gate: with logic inlined, there is no mutable .ts (Stryker mutates .ts,
  not .vue), so `test:mutation` is a documented no-op — behaviour is guarded by the
  100% component-test coverage gate (component tests expanded to keep every inlined
  keyboard branch covered). stryker.config.mjs removed.

Root gates green: build, typecheck (vue-tsc), lint, format:check, lint:pkg,
root test:coverage (31 files / 672 tests, ui-inputs 100%). Published 0.1.0 dist is
unaffected in runtime shape beyond the rename — a 0.2.0 will carry the new names.

Both design points addressed in 59f6293 — and you were right that I'd left your comment unactioned; I'd only worked the CI blocker.

Naming — dropped the Fs prefix for the sibling vocabulary. Checked kendo + emmie: both use compound names with no prefix (SingleSelect/FormError are identical across the two; TextInput/FormLabel follow emmie). New names:

was now
FsSelect SingleSelect
FsTextInput TextInput
FsField FormField
FsLabel FormLabel
FsError FormError

Also re-namespaced the theme contract --fs-* / .fs-*--ui-* / .ui-* so the styling matches the ui-inputs family rather than reading as "frontend service".

Internals — inlined, exactly your point. getLabel / sortByLabel / reduceSelectKey were each used only by the select, and fieldErrorId only by the field — extracted purely to feed Stryker's .ts-only mutation glob (the tool wagging the dog). Pulled them back into their components and deleted the internal/ split. Consequence: with logic in SFCs there's no mutable .ts, so test:mutation is now a documented no-op — the behaviour (including every keyboard branch) is guarded by the 100% component-test coverage gate instead. Your call on that trade-off.

Root gates green (measured against the root commands): build, typecheck, lint, format:check, lint:pkg, root test:coverage — 31 files / 672 tests, ui-inputs 100%.

One flag: the published 0.1.0 carries the old Fs* names, so it's now stale — on merge this should ship as 0.2.0 with the new names (and 0.1.0 is worth a npm deprecate). No consumers yet, so low-harm, but noting it.

Ready for your deferred contract pass (a11y / theme-var completeness) whenever.

…ld/FormLabel/FormError, --ui-* tokens)

0.1.0 shipped the old Fs* names; 0.2.0 carries the reviewed API. Merge publishes it via CI (TP grant wired).

Clean at HEAD b3e1a15. Both of the-general's prior blockers are fixed at 61fe2e3 (before HEAD): root vitest.config.ts now hoists @vitejs/plugin-vue so the aggregated vitest run --coverage transforms the 5 SFC suites (was unplugin-vue/vite in per-package config only, invisible to the root run); packages/ui-inputs/README.md reformatted to oxfmt column-alignment in the same commit. Verified live via git show 61fe2e3 + current file contents. No new findings above gate.

Make props required wherever the component is meaningless without them,
keeping only genuinely-defaultable flags/decorations optional.

- FormError: error + id required; drop the internal v-if — the parent
  (FormField) owns the presence decision via `v-if="error"`, so the leaf
  is a pure props->DOM component. Co-locates the guard with the
  describedby toggle in FormField.
- FormField: id required (drop the useId() fallback — a consumer with no
  natural id passes `useId()` at the call site explicitly). label /
  required / error stay optional.
- FormLabel: htmlFor required (a text-slot label with no `for` is an
  unassociated label — an a11y defect, not a valid state).
- TextInput: id + model required (an unbound controlled input can never
  surface what was typed). type / placeholder / disabled / invalid /
  describedby stay optional.
- SingleSelect: already correctly calibrated — no change.

Specs trimmed to the surviving cases; README example carries an id.
All 8 gates green locally (coverage 100%, vue-tsc clean).

Delta re-review since b3e1a15: one authored commit 9685959 (tighten prop contracts to required, 8 files +22/-28). Clean — required-prop tightening introduces no missing-default or breaking-contract issue. Prior blockers (SFC coverage, README format) remain fixed. Still merge-conflicted vs main.

Goosterhof and others added 2 commits July 15, 2026 13:13
ADR-0043 contract-fidelity follow-ups (cheap wins from the deferred pass):

- required state now reaches assistive tech. FormField threads `required`
  into the control slot; TextInput/SingleSelect accept `required` and set
  `aria-required` on the control. Previously the required `*` marker was
  aria-hidden and visual-only — a screen-reader user was never told a
  field was required (WCAG 4.1.2 / 3.3.2). aria-required (not native
  `required`) keeps the error-as-prop model free of browser constraint
  validation.
- SingleSelect listbox accessible name is now the `optionsLabel` prop
  (default 'Options') instead of a hardcoded English literal — was
  untranslatable on non-English territories.
- theme contract completeness: add --ui-error-size (was asymmetric with
  --ui-label-size), --ui-menu-max-height, --ui-option-pad — the last
  spacing/size literals that escaped the --ui-* surface.

Coverage stays 100% (23 tests); all gates green locally.

The combatbox focus-exposure gap (aria-activedescendant + option ids +
aria-selected semantics) is filed as a separate follow-up — it needs its
own test surface and is out of scope for these cheap wins.

Delta re-review at ae33143 (a11y required-state conveyance + close theme-var gaps, 7f +43/-11): clean, no regression in the aria wiring or new theme vars. Full history now clean — prior blockers (SFC coverage, README format) fixed and stable across rounds; CI green, mergeable. APPROVE.
