Changelog

Unreleased

AI kit. llms.txt, llms-full.txt, and a skills/ folder (README, overview, reading, writing, recipes) for tool-assisted development.
Test suite. Vitest unit tests covering: object-form set (deep merge), path-form set (dot-notation, intermediate object creation, numeric segments build arrays), get (existing paths, missing paths, default fallback, falsy values), list (returns live reference), and singleton sharing across importers.
CI. GitHub Actions workflow: Node 18/20/22 on Ubuntu, plus Node 20 on Windows.
vitest.config.ts with self-detecting sibling-alias: in the monorepo, @mongez/reinforcements resolves to ../reinforcements/src for live cross-package edits; in a standalone checkout, it falls back to node_modules so CI is hermetic.

config.set(string) with a single argument now throws TypeError instead of silently replacing the tree. Previously, shape detection was arguments.length === 1, so calling config.set("api.url") flowed into merge(data, "api.url") — and the underlying @mongez/reinforcements merge returns the latest non-plain-object source as-is, clobbering data with the string "api.url". Detection is now typeof key === "object" && key !== null && !Array.isArray(key); non-object single-arg calls raise a clear error directing callers to either pass an object (deep merge) or a (path, value) pair (path write). This is a behavioral break — calls that previously silently corrupted state now throw — but the prior behavior was always a bug; it’s a desirable break.

README rewrite. Marketing-style index with tagline, 30-second tour, API reference, examples, behavior notes, gotchas, related packages.
skills/ folder for AI agents: per-feature reference cards plus cross-feature recipes.

@mongez/reinforcements: ^2.x.x → ^3.1.0. Compatible API for the surfaces this package uses (get, set, merge). The merge array strategy default is still "replace", matching prior behavior. See reinforcements v3 changelog for the full diff.

Public API signatures unchanged. config.set / config.get / config.list keep their TypeScript signatures. The only behavioral change is the throw on invalid single-arg set calls — see Fixed (behavior) above.
