Phase A1 of the multi-person sharing ADR
(docs/adr/multi-person-sharing.md). Each account now gets an X25519
keypair at registration: the public half stored plaintext, the private
half wrapped under the account DEK and stored as opaque ciphertext. The
keypair is generated client-side; the backend adds no crypto deps and
stores everything verbatim, preserving the zero-knowledge contract.
This change only introduces the keypair and threads it through the auth
flows — it is not consumed yet. It unblocks Phase B (profile sharing)
without touching the data model or the ~11 frontend encrypt call sites,
which is Phase A2 (per-profile DEKs).
Backend:
- User model: identity_public_key, identity_private_key_wrapped{,_iv}
(all Option<String>, backward compatible).
- RegisterRequest/AuthResponse carry the 3 fields; register + login
echo them. No changes to change_password/recover (DEK value is
unchanged across both, so the wrapped private key is too).
- 2 new integration tests: round-trip through register/login, and
optional-fields backward compat.
Frontend:
- crypto/keys.ts: generateIdentityKeyPair, wrapIdentityPrivateKey,
unwrapIdentityPrivateKey + in-memory identity store mirroring the DEK.
- types/api.ts: AuthTokens + RegisterRequest extended (removes an
existing `as any` cast).
- useStore register/login/logout + UnlockPage unwrap the private key
alongside the DEK.
- 3 new crypto tests (X25519 lifecycle, wrong-DEK rejection, distinct
shared secrets); skip gracefully where the runtime lacks X25519.
Backend: cargo test + clippy green. Frontend: npm test + tsc green.
Also gitignore .zcode/ (local tooling artifact).
Backend changes (frontend + tests follow in next commit):
Dose scheduling:
- New DoseSchedule struct (times_per_day + days_of_week) as a top-level
plaintext field on Medication. Create/update requests accept it.
- Revised get_adherence: computes scheduled_doses from the schedule over the
period (days_of_week filtering), so missed doses are now reflected.
Falls back to taken/total_logged when no schedule.
Health stats zero-knowledge:
- HealthStatistic model now uses opaque encrypted_data blob (like medications).
Only recorded_at stays plaintext (filterable/sortable).
- HealthStatResponse wire type. Handlers echo opaque blobs.
- Removed the trends endpoint (server can't compute trends on ciphertext;
frontend computes them client-side after decrypting).
- Deleted the dead HealthData model (kept EncryptedField which it defined).
Verified: backend 24 tests, 0 clippy warnings.
Rate limiting (closes the last security gap #3):
- New RateLimiter: in-memory fixed-window IP-based limiter (std::sync::Mutex
HashMap, no new deps). Configurable via RATE_LIMIT_MAX (default 100) +
RATE_LIMIT_WINDOW_SECS (default 60) env vars.
- general_rate_limit_middleware now reads ClientIp from request extensions and
rejects with 429 + Retry-After header when over the limit. Wired via
from_fn_with_state in app.rs. Lived on AppState as Arc<RateLimiter>.
- Deleted the dead auth_rate_limit_middleware (never wired).
- 3 unit tests (allows up to N, independent IPs, window reset).
E2E crypto lifecycle test:
- Full zero-knowledge round-trip against jsdom's real Web Crypto: setup →
encrypt → verify ciphertext → unlock with password → decrypt → recover via
phrase → rewrap under new password → decrypt. Plus wrong-password/wrong-phrase
failures and cross-user key isolation.
- Fixed wrapDek/unwrapDek: base64-encode raw DEK bytes (was using TextDecoder
which produced non-base64), and make unwrapped DEK extractable (needed for
rewrapDek to export).
Verified: backend 24 tests 0 warnings; frontend 24 tests, build clean.
P1 items #6 (JWT expiry) and #7 (refresh/logout routes) were already delivered
in the P0 pass. This commit covers the two remaining P1 items:
#9 — Replace dangerous handler-level .unwrap() calls (13 sites):
* handlers/users.rs: 5x ObjectId::parse_str(&claims.sub).unwrap() in
get_profile/update_profile/delete_account/get_settings/update_settings now
return 401 on a malformed subject instead of panicking (matches the guard
already used in change_password).
* handlers/auth.rs: the login user.id.ok_or_else(..).unwrap() was a latent
panic bug — the crafted 500 response was discarded. Now returns the clean
500 via match.
* handlers/health_stats.rs: 6x state.health_stats_repo.as_ref().unwrap() now
return 503 SERVICE_UNAVAILABLE if the feature is unconfigured, mirroring the
interactions.rs pattern.
* Left untouched: 14 test/boot-time unwraps and 7 infallible ones (header
literal parsing, infallible TryFrom). The 3 borderline model-layer
inserted_id unwraps are flagged for later.
#8 — Rewrite the broken integration tests against a real test DB:
* Split the crate into bin+lib: new src/lib.rs + src/app.rs (build_app), with
main.rs now a thin entrypoint. Tests build the exact production router
in-process instead of hitting a live server on a hardcoded port.
* tests/common/mod.rs: helpers that connect to Mongo, build a fresh AppState
against a unique per-process DB (normogen_test_<uuid>), and tear it down.
A 1s connectivity probe makes tests skip gracefully when Mongo is absent, so
'cargo test' stays green without Mongo — CI runs them for real.
* Rewrote tests/auth_tests.rs and tests/medication_tests.rs with the ACTUAL
API contracts (POST /register {email,username,password}; response has token
+ refresh_token, not access_token; register returns 201). Covers register,
login (right/wrong password), auth enforcement, refresh rotation + reuse
detection, logout, and password-change invalidating old tokens.
* Added a 'test' CI job with a mongo:7 service container running
cargo test --all-targets.
* Synced scripts/test-ci-locally.sh: fixed the stale -D warnings (CI is
non-strict) and the reverted 'Docker Buildx' claims; added unit + integration
test steps with a Mongo skip note.
Verified: cargo fmt --check clean, build + clippy --all-targets clean.
Full 'cargo test': 18 unit + 9 auth + 4 medication = 31 passed, 0 failed
(integration tests skip cleanly when MongoDB is unreachable).
- Apply rustfmt to all Rust source files in backend/
- Fix trailing whitespace inconsistencies
- Standardize formatting across handlers, models, and services
- Improve code readability with consistent formatting
These changes are purely stylistic and do not affect functionality.
All CI checks now pass with proper formatting.

which is a critical MVP feature for Normogen.
Features Implemented:
- 7 fully functional API endpoints for medication CRUD operations
- Dose logging system (taken/skipped/missed)
- Real-time adherence calculation with configurable periods
- Multi-person support for families managing medications together
- Comprehensive security (JWT authentication, ownership verification)
- Audit logging for all operations
API Endpoints:
- POST /api/medications - Create medication
- GET /api/medications - List medications (by profile)
- GET /api/medications/:id - Get medication details
- PUT /api/medications/:id - Update medication
- DELETE /api/medications/:id - Delete medication
- POST /api/medications/:id/log - Log dose
- GET /api/medications/:id/adherence - Calculate adherence
Security:
- JWT authentication required for all endpoints
- User ownership verification on every request
- Profile ownership validation
- Audit logging for all CRUD operations
Multi-Person Support:

- Caregivers can track family members' meds
- Profile-based data isolation
- Family-focused workflow
Adherence Tracking:

- Configurable time periods (default: 30 days)
- Tracks taken, missed, and skipped doses
- Actionable health insights
Files Modified:
