tmu 52ce655d8e 👷 Gate CI at 100% coverage

test:ci now runs c8 with --all --include "src/**/*.ts" --100, so the
build job fails when any runtime file under src/ is untested. --all is
what makes the gate non-vacuous: without it c8 counts only the files the
suite happened to load, and a new untested module stays invisible.

Add src/index.test.ts to load the public barrel, which was previously
never imported at runtime and so read as 0% under --all. matcher-shared.ts
is types-only (an empty runtime image) and carries a file-level c8 ignore
with the reason.

Why 100% and the rejected alternatives: development/ci.md § Coverage
threshold.

Unreleased

gate CI at 100% coverage: test:ci runs c8 with --all --100 over src/, and a test loads the index.ts barrel so it is measured
pin the duplicate-tag union collapse (members sharing a tag dispatch through one handler) with tests
track a TypeScript 5.0 baseline in the backlog

0.8.0 - 2026-09-23

reject a universe that mixes a literal with a broad type (e.g. "a" | \x-${number}``), which the finite-literal gate let through
narrow the tagged-union matcher's handler parameters for a union-valued or optional discriminant, and its fallback to the unhandled tags, instead of passing never

0.7.1 - 2026-09-23

upgrade dependencies

0.7.0 - 2026-09-23

reject broad universes (string, number, template literals) and value/stringification collisions (true | "true", 1 | "1") at the factory
type handler parameters by the matched member, so a standalone "true" universe is typed "true" rather than true

0.6.0 - 2026-09-22

add getTaggedUnionMatcher / getTaggedUnionMatcherW for discriminated unions
rename the primitive matcher to primitive-union: getMatcher / getMatcherW → getPrimitiveUnionMatcher / getPrimitiveUnionMatcherW, and src/primitive.ts / src/primitive.test.ts → src/primitive-union.*

0.5.0 - 2026-09-21

reject a fallback when the handler map already covers the universe
allow boolean, null and undefined in the matcher universe

0.4.0 - 2026-09-20

move the _ fallback out of handlers

0.3.0 - 2026-09-18

condensed primitive matcher factories down to 2 from formerly 4
house shared test helpers under src/util/__tests__/

0.2.0 - 2026-09-16

allow ternaries and lowercase comments in oxlint
switch src/primitive.ts prose from block comments to line comments
remove the template's match/P example modules and their documentation, and point src/index.ts at the primitive matchers

0.1.8 - 2026-09-16

upgrade dependencies
ignore @types/node in maintain:outdated (misleading latest dist-tag)
require extremely concise prose in development/

0.1.7 - 2026-09-16

require a short summary under [Unreleased] in the changelog before a branch is finished
let create:branch start from a main that is ahead of its upstream, so a finished merge no longer blocks the next branch until it is pushed

0.1.6 - 2026-09-15

restructure the documentation: README.md for users, CONTRIBUTING.md for contributors, and development/ for the decisions, rejected alternatives and known issues
document the decisions and known issues for CI, tooling, testing, publishing and the workflow

0.1.5 - 2026-09-15

improve CI configuration

0.1.4 - 2026-09-14

fix CI to node from custom image
