# Changelog
+## [1.4.34.5] — 2026-05-17 — Audit follow-on: critical-path tests + iOS textarea zoom
+
+Follow-on to v1.4.34.4. Two batches: the missing critical-path
+integration tests the test-coverage audit flagged, and the textarea
+viewport-zoom fix the mobile-deep audit flagged as F-5.
+
+### Tests
+
+- **24 new integration tests across 5 files** closing the critical
+ gaps from `.planning/round-audit-test-coverage.md`:
+ - `tests/integration/auth-password-change.test.ts` pins the v1.4.34.3+
+ `destroyAllSessions` three-transport revocation contract
+ end-to-end (Session.deleteMany, ApiToken.revoked, RefreshToken.revokedAt).
+ - `tests/integration/admin-reset-password.test.ts` mirrors the same
+ contract for the admin-driven reset.
+ - `tests/integration/withings-oauth.test.ts` covers connect /
+ callback / disconnect plus state-token replay rejection.
+ - `tests/integration/passkey-register.test.ts` covers register-options
+ + register-verify + tampered-attestation rejection + challenge
+ single-use.
+ - `tests/integration/cache-invalidation-coverage.test.ts` grids the
+ v1.4.34 IW-G invalidation matrix across 5 write surfaces.
+- Integration suite goes from 197/50 to 222/55. tsc + lint clean.
+
+### Mobile
+
+- **Five textareas no longer trigger iOS Safari zoom-on-focus.** The
+ Coach composer, bug-report description, admin feedback note,
+ medication-side-effects notes, and medication-intake JSON import all
+ shipped `text-sm` (14 px). iOS Safari zooms the viewport whenever an
+ input renders below 16 px. Switched each to `text-base sm:text-sm`
+ so the mobile baseline clears the floor while desktop keeps the
+ compact look.
+
## [1.4.34.4] — 2026-05-17 — Audit-driven hotfix bundle (security, UX, code-quality, docs)
A consolidated hotfix landing the findings from a six-axis audit

+ * - register-verify with a valid (mocked) attestation persists a

+ * - register-verify with a tampered attestation responds 400 and
+ * does NOT persist a Passkey
+ *
+ * `@simplewebauthn/server` runs cryptographic verification we can't
+ * fake against real WebAuthn output in a unit-test setting; the helper
