-**Entry Identity & Links** (the contract `_extract_entry_id()` in views_api.py relies on):
-- The `entry-id` **transaction metadata** is the single canonical entry identifier. Every libra-authored entry formatter (`format_expense_entry`, `format_receivable_entry`, `format_income_entry`, `format_revenue_entry`) writes it. All id resolution (pending list, user journal, approve, reject) reads it — never parse links to recover an id.
-- Typed links `exp-{id}` / `rcv-{id}` / `inc-{id}` exist for **settlement tracking** (BQL queries match settlements to source entries by these links). They duplicate the id but are not the identity source.
-- A user-supplied `reference` (invoice number, receipt id) becomes **its own sanitized link**, verbatim — never fused with the entry id, never displacing a system link. Two entries sharing a reference share the link (desired Beancount semantics).
-- `ln-{payment_hash[:16]}` links mark Lightning payments.
-- Legacy ledger history (pre-dfdcc44) carries a single `libra-{id}` link and no `entry-id` metadata — `_extract_entry_id()` falls back to parsing it. Do not write `libra-` links in new code.

-### Environment gotchas (each cost a failed run on 2026-06-12)
-
-- **`LNBITS_EXTENSIONS_PATH` is the *parent* of an `extensions/` dir** —
-  lnbits scans `{path}/extensions/` (`lnbits/app.py`,
-  `build_all_installed_extensions_list`). For extensions at
-  `~/dev/shared/extensions/libra`, pass `~/dev/shared`. Pointing it at
-  `~/dev/shared/extensions` makes libra invisible: zero extensions install,
-  migrations never run, and every test errors with
-  `no such table: extension_settings`.
-- **Set `LNBITS_DATA_FOLDER` to a fresh temp dir explicitly.** The
-  conftest's `os.environ.setdefault` redirect is not always effective;
-  reusing a previous run's database fails `first_install` with
-  "Username already exists" during app-fixture setup.
-- **`LNBITS_KEY_MASTER` (32-byte hex) is mandatory on lnbits dev** — the
-  signer migration aborts startup without it (issue lnbits#9
-  encrypt-at-rest). Any random value is fine for tests.
-- **lnbits `main` does not work**: extensions importing
-  `lnbits.core.signers` fail to load, and libra's app fixture errors.
-
 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.
