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).
