intake: a duplicate card that refuses a purchase must say what to do instead

The header (merchant, date, total) is a purchase's identity here, so a genuine
second identical purchase — two of the same coffee, one shop, one day — reads
as a re-share and is refused. That default is right; a re-share is far commoner
than a repeat. But the card said only "Nothing was changed", which is a dead
end: the money is real and the ledger silently never gets it. Say to add it in
the app.

+had pointed the suite at **postgres-pantry** — whose database it would have
+TRUNCATEd had the credentials happened to match. A loopback address cannot be
+reassigned to another container, which is why the published port wins.
+
+**Two guards, and both matter.** `helpers.ts::assertTestDatabase` refuses to
+truncate anything whose `current_database()` is not `personal_test`, and the
+suite runs `fileParallelism: false` because every file shares that one database
+and `resetDB()` TRUNCATEs it.

+**A fresh checkout or worktree needs `npx prisma generate` first.** The client is
+generated into the gitignored `src/generated/prisma`, so without it every test

 ### Cash and reconciliation
 
-`payment_method = 'cash'` excludes a transaction from reconciliation via the
-`notCash()` fragment in `queries.ts`. Cash never appears on a statement, so
+`payment_method` in (`cash`, `credits`) excludes a transaction from
+reconciliation via the `needsCardMatch()` fragment in `queries.ts` (named
+`notCash()` when it only knew about cash). Cash never appears on a statement, so
 without it a cash entry sits in the pending queue forever being offered matches
 within 3 days and 1% on amount — and accepting one is silently destructive:
 reconciled manual rows are filtered out of every query, so the cash spend
 disappears while the card transaction it matched claims to be that same spend.
 
-Only cash is excluded. Bank transfers *do* appear on a statement now that
-transaction accounts are imported, and NULL means unknown — both stay
-candidates, preserving the behaviour of every pre-existing row.
+`credits` is the same shape for a different reason: a gift card or store balance
+already paid the bill, so no card leg is ever coming. `bankLabel()` therefore
+renders those rows **"Gift Card"** rather than "Manual" — "Manual" reads as
+"still awaiting a card line", which is wrong here.
+
+Only those two are excluded on payment method. Bank transfers *do* appear on a
+statement now that transaction accounts are imported, and NULL means unknown —
+both stay candidates, preserving the behaviour of every pre-existing row.
+
+**The vocabulary lives in three places and drifted between them (fixed
+2026-08-17).** Migration 0018 admitted `credits` to the CHECK constraint for the
+order pipeline; the `VALID_METHODS` literal in `PATCH /api/transactions/[id]`
+and the add-transaction dropdown were never updated. So the database held 372
+gift-card rows carrying a value the UI could not offer and the API answered 400
+for — a hand-entered gift-card purchase silently took the NULL default, and NULL
+*is* reconcilable, so it joined the queue to be offered matches that cannot
+exist. `src/lib/payment-methods.ts` is now the single list (mirroring
+`statement-types.ts`), and both routes validate against it.
+`src/__tests__/integration/payment-methods.test.ts` asserts it against
+`pg_get_constraintdef` and evaluates `needsCardMatch()` in real SQL, so the next
+migration that widens the constraint fails the suite instead of drifting
+quietly.
+
+**Account-feed rows are NOT excluded, and the removed exclusion is worth
+knowing about.** There was an `awaitsStatementLine()` predicate here, added with
+the Frollo importer on the premise that a feed row is the account's own ledger
+entry with no statement line coming. That premise was asserted and never tested.
+It was false for almost every account: 422 of the first 550 imported rows already
+had a statement twin.
+
+What matters is how it got in. The queue jumped from 8 to 558 the moment the feed
+landed, and that jump was read as noise and filtered out. **The queue was right** —
+those rows genuinely were provisional entries awaiting statement lines — and
+filtering it removed the only mechanism that would ever have collapsed them, so
+the duplicates became permanent instead of transient and stayed invisible until a
+human saw one salary payment listed twice in two currencies.
+
+A feed row belongs in the queue. Queue volume is solved **upstream**, by not
+importing rows the ledger already holds (`LEDGER_MATCH_DAYS`), never downstream
+by hiding the ones that are there. If a genuinely statement-less feed is ever
+added, give it its own predicate and prove the premise with a query first.

+`batch_id`, 1–6 `file`s) is the finance half of the share-sheet intake; design
+and the cross-repo contract are in smarthome `plans/intake-router-slice-plan.md`
+§11 (C1, C2, C5 live here; C3/C4 are pantry-app; C6 is n8n + compose).
+
+- **Order of operations is the plan's and is load-bearing:** persist
+  `intake_batches` row → classify each file → ONE LiteLLM call for the whole
+  batch (`cloud-budget`, `temperature 0`, strict `json_schema`; PDFs go in as
+  `unpdf` text, never pixels) → header `(merchant, date, total)` → merchant
+  kind → duplicate check → reconciliation → match → act. `src/lib/intake-rules.ts`
+  holds the pure decisions, `intake-router.ts` the orchestration.
+- **Match is `(platform, merchant, date, total)`, exact, never widened.** A
+  miss or an ambiguity returns candidates (same merchant ±3 days) with
+  `intake_use_candidate` / `intake_create` buttons; a transaction is created
+  only on the explicit tap, ING-10-style (`statement_id NULL`, `owner_id` from
+  `shared_by` → `participants.email`, else `DEFAULT_OWNER_ID`;
+  `source='intake'`, `source_ref=batch_id` so a second press is a no-op —
+  written as `ON CONFLICT … DO NOTHING`, because a SELECT-then-INSERT loses a
+  double tap). A non-AUD receipt is booked the way `order-ingestion.ts` books
+  one: `amount` native, `amount_aud` **NULL**, `foreign_currency_*` set — no FX
+  rate exists at intake and inventing one is worse than admitting there is none.
+- **A NULL platform means "no platform", not "any platform".** An in-store tap
+  (`coles`, `woolworths`, `other`) matches only rows whose `expense_metadata`
+  carries no platform of its own. The wildcard reading let a till receipt match
+  the Uber Eats order for the same shop on the same day and overwrite its items.
+  The **candidates** query is the opposite and deliberately so: it has no
+  platform filter at all, because the card is a human choice shown precisely
+  because the exact key missed — the platform is one of the things that may be
+  wrong, so the list must widen there, not narrow.
+- **The Create tap re-runs the match before it inserts**, and checks for a
+  resolved sibling batch. The card is minutes old by the time it is pressed and
+  the email/order bridge books orders on its own schedule; `findDuplicateBatch`
+  ignores *unresolved* batches by design, so two pending cards for one order
+  would otherwise each book it.
+- **One `expense_metadata` row, agreed on by every query that resolves one.** A
+  transaction can own a row *and* be the `matched_transaction_id` of another;
+  `matchTransaction` returns the row it resolved through and `replaceLineItems`
+  writes to exactly that one. Every reader orders by
+  `(transaction_id = $1) DESC **NULLS LAST**, id` — the match, the write, the
+  order-detail GET, `getTransactions`' provenance LATERAL, `merchantForTransaction`
+  and the Slack details modal. The `NULLS LAST` is load-bearing: Postgres orders
+  `DESC` as `NULLS FIRST` and the row that merely *points* at the transaction has
+  a NULL `transaction_id`, so the clause meant to prefer the owned row preferred
+  the other one. Measured 2026-08-21: 667 rows, 147 pointing-only, **zero**
+  transactions resolving to more than one row — the ordering changes nothing
+  today and exists so the readers still agree when multiplicity appears.
+- **The create is guarded by a transaction-scoped advisory lock on the
+  PURCHASE**, not the batch. `ON CONFLICT (source, source_ref)` handles a double
+  tap on one card; two *different* batches for one purchase have different
+  `source_ref`s and both clear their match and duplicate checks before either
+  inserts. The lock has to live inside `withTransaction` (`src/lib/db.ts`):
+  `queryRaw` is `$queryRawUnsafe` on a **pooled** client, so every call is its
+  own implicit transaction and `pg_advisory_xact_lock` taken in a statement of
+  its own is released before the next statement runs. The loser reports
+  `duplicate` pointing at the winner's transaction — the same answer the
+  sequential path gives.
+- **`replaceLineItems` snapshots the undo baseline BEFORE it writes, on both
+  paths**, and treats an UPDATE that touched no row as a failure rather than a
+  success. The metadata INSERT is `ON CONFLICT (transaction_id) DO UPDATE` and
+  carries the batch's **currency** — a hard-coded `'AUD'` made `OrderDetails`
+  print `$` on a USD order, because it prefers `expense_metadata.currency`.
+- **`intake_batches.previous_line_items` is the undo baseline, written once.**
+  Returning whatever the write just read makes a pantry retry get its own write
+  back as the "previous" state, so undo restores the thing it undid. Recorded
+  under `COALESCE(previous_line_items, …)` and read back.
+- **Grocery never writes finance here.** The ORIGINAL files go to pantry
+  `POST /api/capture` with `intake.finance_target_transaction_id` +
+  `finance_action: enrich|create`; pantry's confirm calls
+  `PUT /api/transactions/[id]/line-items` back (C4), which is why that route
+  accepts `RECEIPT_INGEST_TOKEN` too. Files are kept under `INTAKE_FILE_DIR`
+  keyed by sha256 so a later "Groceries" tap can still forward them.
+- **Reconciliation is against the printed item subtotal, not the total.** A
+  delivery order's total is items + fees − promotions ($118.94 of Coles lines
+  became $85.74), so checking lines against the total would hold every
+  delivery order. Tolerance $1 or 2%; a failure is `held`, nothing written.
+- **Names stay verbatim.** Burgertory calls its burgers "Michael" and "Joel";
+  the prompt forbids canonicalising and the stored shape is the order lane's
+  (`qty`, `description`, `amount`, `options`) so `order-details.tsx` renders it.
+- Statuses beyond the contract list: `ask` (the "Groceries or a meal?" holding
+  state), `held`, `error` (502 — model or pantry down; the batch row says so).

+
+There is **one** import path — the CSV import modal — and Frollo goes through it
+like any other file. A bespoke Frollo importer, API route, CLI and two scheduled
+n8n workflows existed for a day and were deleted on 2026-08-13: net −1,152 lines.
+
+**The rule that made the rest unnecessary is statement coverage.** Each account's
+newest `billing_end_date` is a watermark; a row on or before it is already in the
+ledger. On the real 2,607-row export that leaves **171 rows** — with no account
+allowlist and no credit-card exclusion, because cards have current statements and
+drop out on their own. Every bit of the deleted apparatus was doing by hand what
+`getStatementCoverage()` does generically.
+
+Note what this replaced. The first attempt asked whether a row's date fell inside
+a statement's min–max *window*, which for accounts whose statements span 182 to
+460 days swallows a year and answers nothing — it let 422 duplicates into 550
+rows. Amount-matching cannot substitute either: the two sources decompose the
+same event differently, bundling a Wise transfer fee into the transfer (10001.13)
+where the statement itemises it (10000.00 + 1.13).
+
+**Map these optional columns or lose something silently:**
+
+| Column | Without it |
+|---|---|
+| **Account** | nothing is excluded — you review the whole file |
+| **Currency** | a foreign row is stored as if AUD (USD 10,782 → A$10,782) |
+| **Row ID** | a re-import duplicates instead of no-opping |
+
+Leave **Category** unmapped for an aggregator: its spend categories are not
+trusted, and you set them per row in the review step.
+
+**Two bugs fixed the day this shipped, both of which the flow depends on:**
+`batchInsertCSVTransactions` accepted a `category` and then omitted it from the
+INSERT column list, so every category chosen in review was discarded and the
+trigger wrote `'other'` — not cosmetic, because an uncategorised credit is
+admitted by `NET_SPEND_ROWS` and negated by `SPEND_SIGNED`, so 62 imported
+transfers cancelled **$74,338** of spend while counting as no income. And the
+path had no idempotency at all: `row_index` is assigned MAX+1 every run, making
+`uq_transaction_identity` structurally unable to fire. It now writes
+`source`/`source_ref` with `ON CONFLICT DO NOTHING`.
+
+**The in-file duplicate warning is not redundant with `source_ref`.** A CDR
+re-consent re-exports an account's whole history under fresh ids while the
+originals survive — 385 twins in one 2,563-row export, doubling every salary
+payment. Fresh ids mean `source_ref` sees new rows, and 385 is not visible by eye

+### Zip, and the three things a BNPL account needs (2026-08-15)
+
+24 statements, Dec 2020 → Jun 2026, all balance-asserting at $0.00. Zip is a
+credit account, so importing it changes how three existing row types must read.
+
+**1. A repayment leaving the bank is a duplicate ONLY where a Zip statement
+covers the purchases.** Zip's own `Payment` rows are already `transfers`. On the
+bank side, `ZIPPAY*` debits are the same money — but only 2 of 8 fall inside a
+Zip statement period. Those two are now `transfers`; **the other six must stay as
+spend**, because for those periods the bank debit is the only record the purchase
+ever happened. Moving all eight would have deleted $703.35 of real spend. Same
+statement-coverage rule as the CSV importer, and the same trap.
+
+**2. `Account Credit` is cashback, and Zip labels its three money-in types
+differently.** `Payment` = repayment from the bank. `Refund <merchant>` = a
+genuine merchant refund. `Account Credit` = Zip cashback — 34 rows, $740, round
+amounts ($20 ×20, $30 ×10, $10 ×4), with no matching debit from any bank account.
+
+Gemini filed the identical description two ways — 23 as `other` (which *subtracts*
+from spend) and 11 as `transfers` (excluded entirely) — so one thing was doing two
+opposite things. All 34 are now `shopping` + `credit`, **netting against spend**:
+cashback lowers what a purchase actually cost, which is how `NET_SPEND_ROWS` /
+`SPEND_SIGNED` already treat a refund. Filing it as `income` was rejected for the
+reason the Up item sales note gives — it flatters `net = income − spent` and mixes
+non-earnings into the salary line. Ties to the **Cashback tracking (ING-6)** epic;
+a dedicated `cashback` category would need the CHECK constraint, the TS mirror,
+and a decision in every analytics fragment, so it was not done here.
+
+**3. A gift card stays spend.** Prezzee is $1,580 of the history. Stored value is
+tempting to call `transfers`, but that only works if every downstream purchase is
+logged — it is not, for 2020. Identical reasoning to the ATM-withdrawal rule.
+
+All 137 Zip rows are categorised; net spend is $11,135.11 against $10,085.11 of
+`transfers`. **Statement 200 (Sept 2021) came through incomplete** — no
+`billing_end_date`, no balances, 2 rows — so it is the one statement not covered
+by `uq_statement_identity` (the index is partial on `billing_end_date IS NOT
+NULL`) and a re-import would duplicate it. Worth re-processing paperless doc 296.

+### Spend is gated on MY_SPEND_SCOPE, not OWNER_SCOPE (2026-08-15)
+
+**Ownership is not a precondition for an expense being yours.** Every spend
+analytic used to gate on `OWNER_SCOPE = $1`, with `mySplitOf` scaling *within*
+that gate — so your half of a shop Sonu paid for counted as **zero**, in monthly,
+daily, merchants, subscriptions, fees and the budget page. 167 rows / **$3,210.91**
+across Jan–Jul 2026, worst in April (+$1,354.83, the Europe trips). Meanwhile
+`getParticipantBalances` booked the matching debt correctly, so the app could say
+you owed her for a shop while insisting you had not spent anything on it.
+
+Use `MY_SPEND_SCOPE()` — `owner = me OR I hold a split` — for anything measuring
+what *I* spent. `OWNER_SCOPE` is still right for anything measuring an **account**:
+the income and investment lines in `/analytics/monthly`, and the statement-level
+fee rollup in `/analytics/fees` (which reads `statements`, where splits are
+meaningless).
+
+**`myShare` had to change with it, and widening the gate alone would have been
+worse than the bug.** Its old third fallback, `100 - everyone else`, is the
+*payer's* remainder — on someone else's unsplit row it returns 100 and would have
+moved their entire bill onto you. It now branches on ownership:
+
+- **My row** — unchanged: explicit split, then `my_share_percent`, then the
+  remainder.
+- **Their row** — an explicit split row only; absent means **0**.
+
+`my_share_percent` is deliberately not consulted on someone else's row. It is one
+unscoped column on `transaction_overrides` writable by anyone who can see the row,
+so "my" can only mean the owner's. All 402 rows carrying one today are owner-side.
+
+That 0 is what makes the wider gate safe: admitting a row can never add more than
+the share actually held. Tested both ways in
+`src/__tests__/integration/analytics-sql.test.ts` — the discriminating cases are
+all ones where you hold **no** split on someone else's row, because that is the
+only place old and new disagree.
+
+`MY_SHARE_PCT` in `queries.ts` mirrors `myShare` in subselect form for the
+transactions list (which has no viewer-scoped `ts` join). A test asserts the two
+agree row for row across seven fixture shapes — keep it that way, since the list
+is the drill-down for these totals.
+
+**No historical restatement:** every non-owner split is 2026-dated. The 1,266
+pre-2026 SplitMyExpenses splits are all on rows you own, so nothing before the
+cutover moves.
+
+### Changing who paid (2026-08-15)
+
+Owner was **write-once for every ingestion path** until now — a pantry receipt
+hardcodes `DEFAULT_OWNER_ID` (`receipt-ingestion.ts`), and there was not one
+`UPDATE ... SET owner_id` in `src/`. A shop the other person paid for was
+permanently filed as yours.
+
+Two routes, because the owner lives in two places:
+
+- **`PATCH /api/transactions/[id]` with `owner_id`** — manual rows only
+  (`statement_id IS NULL`). A statement row returns 400 `statement_owned` and
+  points at the statements page; its effective owner is
+  `COALESCE(t.owner_id, s.owner_id)`, so writing it here would either no-op or
+  detach one row from the account it was extracted from.
+- **`PATCH /api/statements/[id]` with `owner_id`** — the statements page has had
+  this dropdown since it was built, wired to a route with **no PATCH handler**.
+  Every change 405'd, and `useUpdateStatement` never checked `res.ok`, so it
+  failed silently and the select just snapped back.
+
+**The statement route writes both tables.** 2,194 statement rows carry their own
+`owner_id` against 1,803 that inherit, so updating `statements` alone moves less
+than half and splits one account's history between two people. It updates rows
+matching the *old* owner and returns `rows_moved`; all 2,194 agree today, and a
+row that disagrees was set deliberately and is left alone.
+
+**Reassignment is a one-way door, and the guard is the point.** Access is
+`owner OR holds a split` (`canAccessTransactions`), so handing a row over while
+holding no split removes it from your list and 404s every route that could put
+it back — only the new owner can undo it. The route returns **409
+`would_lose_access`** and the modal offers the two real ways forward: add your
+split first, or "Give it away anyway" (`release: true`). Taking a row *onto*
+your ledger is never blocked — there is no door to close behind you.
+
+Reassignment is a correction to a row you already hold, never a way to reach one
+you do not: `canAccessTransactions` runs first, so claiming a stranger's
+transaction is a 404 before any owner logic runs.
+
+**Splits are deliberately not rewritten.** They record shares, not direction —
+`getParticipantBalances` derives who owes whom from ownership, so a 50/50 flips
+from "they owe me" to "I owe them" untouched, `settled` included. Tested both
+directions.
+
+**Order matters when you do this by hand:** split first, then reassign. The
+reverse locks you out, which is exactly what the 409 exists to stop.
+
+`useUpdateTransaction` also gained the missing `res.ok` check. Without it every
+rejection resolved as success — the modal closed, the list refetched, and the
+edit silently vanished.

 The TypeScript mirror is `src/lib/statement-types.ts` — keep the list, the SQL
 function, and the CHECK constraint in sync when adding a type.
 
+### Bank names are normalised on write (migration 0031)
+
+**`bank_name` is a component of the duplicate check.** `uq_statement_identity`
+is `(bank_name, account_number, billing_end_date)`, so two spellings of one
+institution mean the same statement can be ingested twice without the index ever
+firing. Gemini reads the name off whatever the PDF prints, so the spelling varies
+per *document*, not per account.
+
+Zip exposed it: account `2705256` arrived under four names in sixteen minutes —
+`ZipMoney Payments Pty Ltd`, `ZipMoney Payments Pty Limited`, `Zip Pay`,
+`ZipPay` — with ten more in the queue. It was not unique. 17 `bank_name` values
+represented 13 institutions, and every split pair shared an account number:
+Amex (14/1), Citibank/Citi (8/4), NAB (3/1). Fragmentation also splits the
+statements and transactions bank filters and `by_bank` in `/api/analytics/fees`.
+
+`normalize_bank_name()` + `trg_statements_normalize_bank_name` (BEFORE INSERT OR
+UPDATE OF bank_name) mirror the 0013 `statement_type` pattern, with **one
+deliberate difference: the vocabulary is open.** An unrecognised name passes
+through tidied, never collapsed to a fallback, and there is **no CHECK
+constraint** — a bank this household has never used must be able to arrive
+without a migration, and destroying its name on first contact is worse than
+leaving it unmapped.
+
+Matching is by **prefix, not by enumerated spelling** (`zip%`, `citi%`,
+`%american express%`, `%national australia bank%`), so unseen variants like
+`Zip Co Australia Pty Ltd` normalise with no code change. Branches for Westpac,
+ANZ, HSBC, ING, AMP, Up and CommBank are no-ops today that map *to* the spelling
+already in use — they exist to catch the legal-entity variant a future PDF might
+print.
+
+Wise is deliberately unmapped: `Wise Australia Pty Ltd.` is a single spelling, so
+shortening it would be a rename nobody asked for rather than a merge.
+
+**One institution's national entities stay apart (migration 0032).** A prefix
+generalises past the evidence it was built on: every 0031 merge was provably one
+account, but `citi%` would have flattened Citibank India into Citibank Australia
+on arrival. `hsbc%` and `%american express%` had the same defect. The country now
+comes from the name when the name states it and from the currency otherwise, with
+AUD as home taking no suffix — so nothing renamed (`UPDATE 0`).
+
+Currency alone cannot be the discriminator: **Wise holds AUD, EUR and USD
+accounts under one provider**, so "non-AUD means a different bank" would shatter
+it into three. That is why Wise must stay unmapped, and why mapping any
+multi-currency provider through this function would be wrong.
+
+`N.A.` is deliberately not a country marker — it means "National Association", a
+US legal form printed on Citibank letterhead worldwide including India.
+
+**The residual gap and its tell.** The function cannot know that two names for a
+*new* bank are one institution. That always shows up the same way, so check the
+`statement_identity_drift` view (migration 0033) rather than trusting the map.
+Non-empty means an account is fragmented, by name or by number.
+
+### Account identity is derived, not the raw number (migration 0033)
+
+`account_number` fragments exactly like `bank_name` did, from the same cause —
+Gemini copies what the PDF prints. ANZ's Access Advantage arrived as both
+`4085-56264` (4 statements) and `408556264` (1). Since `uq_statement_identity`
+keyed on it, re-importing one period under the other spelling evaded the
+duplicate check.
+
+`account_number_key` is a **GENERATED ALWAYS** column — `account_number` with
+separators stripped — and the unique index is now
+`(bank_name, account_number_key, billing_end_date)`. **Never write to it;
+display `account_number`.**
+
+Derived rather than rewritten because the raw number is the readable one and
+some of it is structure: Up stores `633-123 / 176540052`, a BSB *and* an account
+number, and flattening it would lose a distinction a human reads at a glance to
+fix a machine problem. Case and the Amex mask (`XXXX-XXXXXX-01000`) are
+preserved — `X` records which digits were redacted.
+
+This is **not** what caused the documented 31-row / $42,040.68 ANZ duplication.
+Statements 107/142/143 overlap on *different* end dates, which that index cannot
+catch at any spelling. Different problem, same table.
+
+`account_owner_mappings` also keys on `(bank_name, account_number)` with its own
+UNIQUE constraint, so any future rename must update it too or strand its rows.
+It is empty today; the migration handles it anyway.
+
+**Normalising `bank_name` broke the N8N new-bank alert, and the fix lives in the
+workflow.** `Check Known Bank` ran
+`SELECT COUNT(id) FROM statements WHERE bank_name = '<raw Gemini name>'`,
+comparing the raw extraction against the now-canonical column *before* the insert
+— so the trigger had not fired yet and nothing ever matched. That branch tags the
+document **pending and holds it for Slack approval**, so every Zip statement
+stalled awaiting a manual click, not merely a noisy alert. It was a regression
+made worse by normalisation: previously a repeat of the same spelling at least
+matched.
+
+Fixed 2026-08-15 by comparing like with like:
+
+```sql
+SELECT COUNT(id) as count FROM statements
+WHERE bank_name = normalize_bank_name('{{ ...summary.bank_name }}', '{{ ...summary.currency }}')
+```
+
+Currency is passed so a genuinely new national entity (Citibank India) still
+alerts. Verified live: the run after the fix took 12s against 30–53s for the
+approval-branch runs before it. Workflow `FysADdFwEtwONQl4` in the smarthome
+repo — **any future change to `normalize_bank_name()` must keep that node in
+step**, since it is the one caller outside this codebase.

+-- that is now a documented property rather than an accident.
+--

+ * `analytics-sql.test.ts` only ever covered the three SQL *fragments*
+ * (EXCLUDE_RECONCILED_SOURCE, NATIVE_CURRENCY, INVESTMENT_SIGNED). Items 2, 3
+ * and 6 of that list had nothing:
+ *
+ *   2. the spend-pace series must use the same spend semantics as the headline
+ *      printed directly above it;
+ *   3. fees and interest must be bounded by an explicit, reported period;
+ *   6. a month in progress must never be compared against complete ones.
+ *
+ * All three fail *silently* when they regress — no error, no empty screen, just
+ * a number that quietly disagrees with the one beside it. That is precisely the
+ * class the review flagged and the reason these are worth the fixture cost.
+ *
+ * The clock is frozen for every test in this file. Two of the three behaviours
+ * are defined relative to "now" (which month is in progress, how far back the
+ * default fees window reaches), so against the real clock the fixtures would
+ * drift out of the routes' windows and the assertions would go vacuous — which
+ * is the failure mode this file exists to prevent, one level up. Only `Date` is
+ * faked: `pg` uses real timers for its connection handling.
