Three advisory paths, closed with the narrowest scoped overrides rather than a
broad upgrade. Each raises exactly the one edge that resolved a vulnerable
version, and each pins an exact release.
PostCSS 8.5.17 (GHSA-r28c-9q8g-f849, high) was reached only through Vite, which
better-auth pulls in via Vitest, and Vite 8.1.4's own range still resolved the
vulnerable version. `vite>postcss` now resolves 8.5.24; one version in the tree.
esbuild 0.18.20 (GHSA-67mh-4wv8-2f99, moderate) was reached only through the
deprecated @esbuild-kit/core-utils, whose pinned range predates the fix. Scoped
to `@esbuild-kit/core-utils>esbuild` on purpose: drizzle-kit already resolved
esbuild 0.25.12 directly and tsx/vite resolve 0.28.1, so a global override would
have dragged those newer, unaffected versions backwards. The vulnerable version
is gone and 0.28.1 is preserved.
Lodash 4.17.21 (GHSA-r5fr-rjxr-66jc high, GHSA-f23m-r3pf-42rh and
GHSA-xxjr-mmjv-4gpg moderate) was reached only through the development-time
Better Auth `auth` CLI's Prisma parser. All three chevrotain packages pin lodash
to exactly 4.17.21, so no in-range release is patched, and the advisories
require >= 4.17.24 — a version the 4.17.x line never published. 4.18.1 is the
lowest fixed release; the override crosses chevrotain's exact pin for that
reason. Verified compatible before applying: 4.18.1 keeps the per-method
CommonJS subpath files chevrotain requires (`lodash/assign`, `lodash/isRegExp`,
and the rest), with the same `main` and no restrictive `exports` field.
Both `pnpm audit --prod` and the full `pnpm audit` now report no known
vulnerabilities, with no ignore, allowlist, or audit-level suppression.
Proven, not assumed: `pnpm install --frozen-lockfile` succeeds; the Better Auth
schema generator still matches the checked-in identity schema, which exercises
the very chevrotain/lodash path that was overridden; drizzle-kit loads the real
config and reports no schema changes against a scratch copy, leaving tracked
migration artifacts untouched; the three Core migrations keep their exact
checksums; and the whole unit and PostgreSQL integration suites stay green.

Adds Core-owned identity contracts, a Core-owned Better Auth database schema
(ekklesia_core_user/session/account/verification), a first-class Core-owned
migration source that coexists with module-owned migrations under the exact
existing migration system, and an explicit Better Auth construction boundary.
No authentication endpoint or sign-in UI is exposed yet (ADR 0010).
