Drop the fixed no-floating-promises header exception from CONTRIBUTING.md
and AGENTS.md; agents must not add a source disable or edit .oxlintrc.json.
Record the split in tooling.md and testing.md: a one-site false positive is a
source disable, a file-class one lives in the test override.
No tests live under scripts/, and every test script (test, test:unit, test:ci,
watch:test) globs only src/**/*.test.ts, so state that. The scripts/**
oxlint scope it was confused with still exists and carries the same
import/no-nodejs-modules exception as the test-helper scope.
The matcher is now two three-overload factories; library.md documents why
the union merge, inferred universe, conditional RequireKeys and cases-first
paths were rejected, and lists the two open issues (the fallback sees all of
T; a redundant _ is still accepted). testing.md records the language server
as the autocomplete oracle, and CONTRIBUTING points the exception at the
matcher's own test file.
The backlog marks the design-doc and autocomplete groundwork done alongside
the adoption.
development/testing.md § Test helpers: why name beats path under
import/no-relative-parent-imports, why the key needs `#`, why the
`__tests__` folder name, and what was rejected (flat placement, tsconfig
paths, rule exemptions).
The spec only exercised the template's match/P example API. Removing it
first lets the modules and exports it imports go next without leaving a
dangling reference.
Type-driven tests: every expectTypeOf pairs an assert, covering the
header matrix (exhaustive vs partial patterns, strict R vs widened
returns, string and numeric keys, _ fallback wiring).
Negative cases use Parameters<typeof factory>[0] assignability because
expect-type's .not.toBeCallableWith collapses to never on these generic
Simplify<>-wrapped signatures.
Same documented expectTypeOf floating-promise false positive as
index.test.ts, so the same file-level disable applies; testing.md
known-issue updated to list both files.
Same decisions, rationale, rejected alternatives and known issues, said with
less padding: ~5,530 -> ~4,730 words (-15%). Every fact from the first draft is
kept; only the wording, duplicated lead-ins and restated context are cut.
The GitHub Flow description and the type-first enforcement sentence still
appeared in both CONTRIBUTING.md and development/. development/ now carries only
the context and rationale that is not in CONTRIBUTING.md.
development/ had restated the actionables that CONTRIBUTING.md owns: the
branching step list, the script prefix list, the feedback-tier rule of thumb,
the commit convention and the type-driven test loop. Those now live only in
CONTRIBUTING.md; development/ keeps the decision blocks and links to the rule.
development/README.md, CONTRIBUTING.md and AGENTS.md state the 'write each fact
once' principle explicitly.
Category files under development/ replace the decision prose that was
scattered through README.md and CONTRIBUTING.md. Each decision is a block with
Decision (YYYY-MM) / Why / Rejected / Known issue; the new library.md records
the public API contract and its limitations. AGENTS.md and backlog.tasks now
point at the new home.
