Add integration test suite

113 passing tests + 3 skipped + 8 xfailed across 10 files, covering user
expense and income flow, admin receivable/revenue, settings + auth gates,
void/reject, manual payment requests, balance display, Lightning auth
paths, reconciliation API, and pure-function units. Runs against a real
Fava subprocess and full LNbits app via asgi_lifespan; the harness
captures the auth-flow / settings / env-var disciplines surfaced during
build-out (see tests/README.md and tests/conftest.py docstring).

Eight xfailed/skipped tests carry full implementations gated behind issues
#38, #39, #40 — they flip back on automatically when those land.

+# Libra extension tests
+
+Integration tests covering the user- and admin-facing flows of the libra extension. Tests run against a real `fava` subprocess and a full LNbits app so they catch behaviour that mocks would miss (BQL semantics, Beancount arithmetic, multi-currency aggregation, HTTP boundary).
+
+## Layout
+
+- `conftest.py` — session-scoped Fava subprocess + LNbits app + user/wallet fixtures.
+- `helpers.py` — high-level wrappers for the common API flows (`post_expense`, `settle_receivable`, `approve_manual_payment_request`, …). One per intention, so test bodies read as sequences of actions rather than HTTP calls.
+- `test_smoke.py` — single end-to-end test; run first to validate the harness.
+- `test_<area>_api.py` — per-flow coverage (entries, balances, settlement, manual payment requests, lightning, reconciliation, settings/auth, void/reject).
+- `test_unit.py` — pure functions (`beancount_format`, `account_utils`, `core/validation`); no harness.
+
+## Prerequisites
+
+The harness requires `fava` on PATH. On NixOS:
+
+```bash
+nix-shell -p python3Packages.fava
+```
+
+Inside the regtest container `fava` is already provisioned.
+
+## Running
+
+From the LNbits source root (with the libra extension reachable via `LNBITS_EXTENSIONS_PATH` or symlinked into `lnbits/extensions/`):
+
+```bash
+# Whole suite
+pytest path/to/libra/tests
+
+# Smoke test only (validate the harness before running everything)
+pytest path/to/libra/tests/test_smoke.py
+
+# One area
+pytest path/to/libra/tests/test_balances_api.py
+
+# Single test, verbose
+pytest path/to/libra/tests/test_balances_api.py::test_mixed_income_expense_nets_correctly -v
+```
+
+The Fava subprocess starts once per session (~1-2s) and is shared across tests; each test creates its own LNbits user so the shared ledger doesn't cause inter-test interference.
+
+## Conventions
+
+- **Tests assert intent, not shape.** Use the helpers in `helpers.py` for the request and assert on the *meaning* of the response (balance values, account names, settlement state), not on incidental keys in the JSON. This keeps tests resilient to non-behavioural API tweaks.
+- **Currency-handling assertions use `pytest.approx`** for `Decimal`/`float` tolerance.
+- **One canonical happy path per flow, plus boundary cases that matter** (voided entries excluded, pending entries excluded, cross-user isolation, auth gate rejection). Don't over-matrix.
+- **Each test creates its own users** via the function-scoped `libra_user` / `libra_user_b` fixtures. The ledger is session-shared and accumulates entries; test isolation comes from unique user IDs, not ledger resets.

+"""Balance display tests — the user-named "mixture of income and expenses
+displayed correctly" scenario.
+
+The balance API returns figures from libra's perspective:
+  - Negative `fiat_balances[CCY]` → libra owes the user
+  - Positive `fiat_balances[CCY]` → user owes libra
+  - Sum across Payable + Receivable + Credit per currency
+    (Credit added per libra-#41: overpayment lands as a liability that
+    libra owes the user going forward, naturally subtracting from net.)
+
+Lifetime totals (`total_expenses_fiat`, `total_income_fiat`) are kept
+separate per the `models.py:93` comment — "original entries only; not net of
+reconciliation" — so they don't reflect settlement activity or credit.
+
+Excluded from the balance query: pending entries (flag `!`), voided entries
+(tag `voided`). Tested explicitly here so the contract is locked in.
+
+Note: this file does NOT cover post-settlement netting; that's blocked on
+issue #33 (settlement leaves both per-user accounts non-zero) and lives in
+the settlement test file.

+    background task doesn't unwind cleanly. Investigation deferred; the
+    auth gates + 404/400 error paths are what we can lock in for now.
+
+The skipped tests carry full implementations so flipping them back on is

+"""Reject / void pending entry flow — `POST /libra/api/v1/entries/{id}/reject`.
+
+Captures the current (pre-issue #24) in-place mutation behaviour:
+
+  - Pending entries (`!` flag) can be rejected by a super user.
+  - Rejection appends `#voided` to the transaction line in the .beancount file
+    (no new transaction posted — this is the only in-place edit path in libra).
+  - Voided entries are filtered out of balance queries.
+  - The reject endpoint only matches pending entries; cleared (`*`) ones return
+    404 because the search loop filters by `flag == '!'`.
+
+PR #34 changes whether the user's `/entries/user` listing surfaces voided rows.
+The test `test_voided_entry_excluded_from_user_journal` documents the current
+("filtered") behaviour; flip it if/when that change lands.
+
+When the reversing-entry refactor in issue #24 ships, these tests will need to
+move from "void via tag append" to "void via reversal transaction." The shape
+of the tests should still hold — what changes is the on-disk evidence.
