Client-side validators (reset-password, invite-accept, first-admin setup,
user-create modal) previously checked password.length < 8 while every
server-side Zod schema required .min(12). External API consumers (or a
confused browser UI) could get past the client check but fail at the tRPC
boundary — or worse, quietly under-enforce policy compared to what
admins expect.
Fix: introduce PASSWORD_MIN_LENGTH (12) and PASSWORD_MAX_LENGTH (128) in
@capakraken/shared and import them from every pre-submit client validator
and every server Zod schema. Single source of truth; drift becomes a
compile error rather than a security finding.
Also hardens the AUTH_SECRET runtime check: in addition to the existing
placeholder-blacklist, production startup now rejects secrets shorter
than 32 chars OR with Shannon entropy below 3.5 bits/char. That covers
low-entropy-but-long values like "aaaa..." (38 chars, entropy 0) which
would have passed the previous checks.
Documented the rotation process for AUTH_SECRET + POSTGRES_PASSWORD in
docs/security-architecture.md §3.
Verified:
- pnpm test:unit — 396 files / 1922 tests passed
- pnpm --filter @capakraken/web exec tsc --noEmit — clean
- pnpm --filter @capakraken/api exec tsc --noEmit — clean

- docker-compose.yml: require ${POSTGRES_PASSWORD} for the postgres service
and the app container's DATABASE_URL. No default — compose refuses to start
without it, mirroring the existing PGADMIN_PASSWORD pattern.
- Dockerfile.prod: move auth/db ENV assignments from persistent ENV lines into
an inline env prefix on the `pnpm build` RUN step. Placeholders are still
available to `next build` but no longer persist in the builder layer or in
the published migrator image (which is FROM builder).
- Dockerfile.dev: add HEALTHCHECK against /api/health and install curl for it.
- .dockerignore: cover nested **/.env*, **/*.pem, **/*.key, **/secrets/**.
- runtime-env.ts: add the CI build placeholder strings to the disallowed-secret
set so a misconfigured prod deploy using the baked-in ARG defaults fails
startup instead of silently running with a known-bad secret.
- .env.example: document the new POSTGRES_PASSWORD requirement.
- CI: write POSTGRES_PASSWORD into the Fresh-Linux Docker Deploy job's .env
(must match docker-compose.ci.yml's hardcoded DATABASE_URL), and provide a
dummy value in the E2E job where compose validates all services' interp.
