A cookie-carrying mutation without Origin and Referer (or with an
unparsable one) is now rejected with 403 csrf_origin_mismatch instead
of passing unchecked. The exception for non-browser clients stays
structural: PAT/bearer requests carry no session cookie and never reach
the check, and a request that does carry the cookie is always checked.
The test harness injects the matching Origin (supertest simulates a
browser page of this instance) with an explicit suppression header for
the negative cases; the Playwright fixture contexts send the header on
their manual seeding calls; release-qa.sh pins APP_BASE_URL and sends
the matching Origin. Dedicated spec covers: missing headers 403,
mismatch 403, unparsable 403, match passes, GETs untouched, PAT
mutation without headers passes, cookie+bearer still checked.

COLLAB_TOKEN_SECRET becomes a root key: every purpose derives its own
HKDF-SHA-256 subkey (deriveTokenKey), and no code path signs with the
root key directly. Collaboration tokens are signed and verified by jose
with HS256 as an explicit allowlist; the sign/verify API turns async at
its three call sites. Unsubscribe tokens move from a purpose-prefix
string to the structural subkey, with a documented dual-verify window
(legacy derivation accepted until 2026-11-01, covering the 90-day TTL
of links in already-sent mail).
The cross-runtime property that justified the homegrown implementation
is now proven by a test: the built CJS and ESM dist artefacts round-trip
tokens in both directions in child processes (jose v6 reaches CJS via
Node's require(esm), pinned Node 22 images). Negative tests cover
cross-purpose subkeys, root-key-signed tokens, alg:none and RS256.

pnpm workspace with apps/web, apps/api, apps/collab, and
packages/shared; strict TypeScript base config, repo-wide ESLint (flat)
+ Prettier, Vitest per package, and root scripts lint/typecheck/test/
build. @dorfteich/shared ships a first health-response helper consumed
by apps/api to prove workspace linking. Existing markdown docs are
reformatted once by the new Prettier setup.

Initial deliverable of the architecture phase: 16 ADRs (stack, CRDT
collaboration, plugin sandbox, import/export, backups, CI/CD), data
model, permission model, real-time collaboration and plugin concepts,
deployment/operations/security documentation, and the milestone roadmap
that the implementation issues are derived from.
