serfowiandClaude Opus 5 c617bc9687 M1 security: close the password backdoor, apply re-review, pin E.164
Acts on an adversarial review of the M1 auth and authorization code.
Five findings fixed; the rest recorded in SECURITY-FINDINGS.md as the
M1 exit criteria rather than left in a tool transcript.

- auth: serve /phone-number/request-password-reset, /phone-number/
  reset-password and /sign-in/phone-number as 404. better-auth's
  phoneNumber() registers all three unconditionally -- they are NOT
  gated on emailAndPassword.enabled:false. Left live they form a
  silent second credential path: request-password-reset stores an OTP
  and sends no SMS (sendPasswordResetOTP was never configured, so the
  owner is never told), reset-password mints a bcrypt credential row,
  and sign-in/phone-number then accepts it forever with no OTP. The
  OTP gate still applies, so this is not remote unauthenticated
  takeover -- it converts one momentary OTP compromise into permanent
  access the victim cannot see or rotate.

- auth: drop bearer(). It accepts the plaintext sessions.token column
  as an Authorization credential, making any single leaked row a
  replayable login. The mobile client it was added for is hypothetical.

- auth: pin E.164 via phoneNumberValidator, and add toE164/isE164 to
  @linkder/shared. phone is UNIQUE and bans are per-account, so
  "+34600111222" and "0034600111222" being separately storable meant
  one handset could hold two accounts and a ban was escapable by
  retyping. 15 tests.

- auth: NEXT_PUBLIC_APP_URL now throws in production instead of
  falling back to localhost, which was silently dropping Secure and
  the __Secure- prefix from the production session cookie.

- pro.upsertProfile: actually apply requiresReReview. It was computed,
  returned to the client and never acted on, so a verified plumber
  could become a verified electrician in another city by ignoring a
  response flag. Now demotes to pending in the same transaction and
  audits it. Trade changes count as material (they did not before) --
  the licence is per-trade. Needed a verified -> pending edge in
  VERIFICATION_GRAPH, which did not exist.

Removed two untracked scratch repro files. The impersonation repro
depended on bearer() for transport and no longer applies as written;
the underlying finding (resolveSession drops impersonatedBy, so admin
actions are audited as the victim) is open and documented.

typecheck, lint, build clean; 127 tests pass.

serfowiandClaude Opus 5 66dd4ac942 M1 (partial): tRPC API layer, storage, and three real fixes
Stands up packages/api so the swipe path stops trusting its caller, and
puts the auth library behind an interface we own.

- packages/api: tRPC v11 with a Session type WE define, not one
  re-exported from an auth library. Swapping providers means rewriting
  one SessionResolver, not touching a router.
- Procedure layers: public / protected / client / pro / verifiedPro /
  admin. Admin routes 404 rather than 403 so they cannot be probed.
- deck router replaces the untrusted server action. Ownership is checked
  on every operation and returns NOT_FOUND, never FORBIDDEN, so job ids
  cannot be enumerated. 23 tests, mostly authorization.
- packages/storage: presigned direct-to-R2 uploads. The server picks the
  key, so a caller can only write under their own user id. 14 tests.

Three defects found and fixed:
- The lazy db Proxy failed drizzle's is(db, PgDatabase) because it did
  not trap getPrototypeOf. Auth adapters dispatch on exactly that check,
  so this would have failed at runtime inside third-party code. Fixed
  and pinned with a regression test.
- The open-request cap was a read-then-write race: concurrent swipes
  could both read 4 and both insert. Now one transaction with the job
  row locked. The cap is checked before the tombstone is written, so a
  rejected swipe leaves no trace and the card stays on the deck.
- superjson was configured in two of the three required places. Without
  the QueryClient dehydrate/hydrate pair, RSC-prefetched data arrives as
  a raw envelope with no type error to warn you.
