On a current account a positive +figure is income. On a credit card a positive figure is a charge. Same number, +opposite meaning, and nothing in the model distinguishes them. + +This plan fixes the account/ingestion semantic boundary and gives the user a +safe, reversible import workflow. It must deliver three observable outcomes: + +1. A known statement cannot be committed to an incompatible or unidentified + account. +2.

Leave the box at its default and you get +`GENERIC`, whose `default_sign` is `None`, which falls through to `as_written` — +and every card charge becomes income. This is the direct mechanism of the +inversion above. The adapter must be detected from statement content; account +binding then validates type/currency compatibility. Account names must never +select parsing or sign semantics. + +**D2 — Account type is hardcoded at commit.** +`src/pfa/ingestion/service.py:227`: +```python +account = self.uow.accounts.get_or_create( + candidate.account_hint or "Main account", candidate.currency +) +``` +`get_or_create(name, currency, account_type="current")` — the third parameter is +never passed (`src/pfa/db/repositories.py:71`). No import path can ever create a +`credit_card` account. There is no account-type selector in the import UI. + +**D3 — One `hsbc` dialect serves two incompatible statement shapes.** +`HSBC/Bank/*.pdf` is a current account with three columns +(`Paid out | Paid in | Balance`). `HSBC/*.pdf` is a Visa card with a single +amount column plus a `CR` marker. `dialect_for_name("hsbc")` returns the same +`Dialect` for both. Consequence on the bank statement: the parser takes the last +number on the line — the running balance — as the amount. + +``` +PDF: 23 Apr 25 DD ADMIRAL INSURANCE 262.11 778.05 +stored: 'DD ADMIRAL INSURANCE 262.11' £778.05 credit/income +``` +26 transaction lines in that PDF produced 9 imported rows, 2 of which are +`BALANCEBROUGHTFORWARD`/`BALANCECARRIEDFORWARD` markers imported as income. +Dialects must be keyed on **(institution, product)**, not institution alone. + +**D4 — `current_cash` will silently break the moment card accounts exist.** +`src/pfa/analytics/service.py:266` excludes only `NON_CASH_ACCOUNT_TYPES = +{INVESTMENT, LOAN}` (`src/pfa/domain/accounts.py:13`). A `credit_card` account's +opening balance would therefore be **added to cash**, and `_cash_delta` +(`src/pfa/analytics/service.py:55`) sums card charges into the cash position even though no cash +moved. There is a second defect: `_cash_delta` returns zero for every transfer, +so a current-account leg that repays a card would not reduce liquid cash. The +fix must filter to liquid asset accounts and sum canonical signed amounts for +all transaction kinds. Merely adding `CREDIT_CARD` to an exclusion set is not +enough. + +**D5 — `debt_payments_minor` reads £0.00 the moment payments become transfers.** +`src/pfa/analytics/service.py:99` computes it as +`_spending(row) where category == DEBT_PAYMENT`, and `_spending` returns 0 for +anything that is not `EXPENSE`/`FEE`. Reclassifying card payments as `TRANSFER` +zeroes a live reported number. Classification and replacement debt metrics must +therefore land together in WP7. + +### Adjacent defects and scope boundary + +Two parser defects move **into** this plan because they invalidate the stated +real-corpus acceptance gate and corrupt categorisation evidence: + +- AMEX PDF statement-year inference must read the statement period instead of + falling back to the system year. +- AMEX/HSBC PDF two-date rows must populate `transaction_date` and + `posted_date`, removing the posted-date prefix from descriptions. + +Measured categorisation changes from 1/24 with the stray prefix to 19/32 once +clean.

Net-worth opening +contribution is therefore positive for assets and negative for liabilities. +`opening_balance_as_of` names when that value was true; do not call it merely +`balance_as_of`, which could be mistaken for a live/current balance. + +The baseline date is an **end-of-day** balance. Transactions on that date are +already reflected and must not be added again. A statement opening balance at +the start of 1 January is therefore stored as the 31 December end-of-day +baseline. This makes the inclusion rule unambiguous: `baseline_date < +transaction_date <= as_of`. + +If `as_of < opening_balance_as_of`, that account's historical balance is +unknown unless an earlier accepted balance snapshot covers the date. A missing +baseline date is also incomplete coverage; migrations must not invent one. + +Do not overload the opening value with available balance, credit limit, +statement balance, or current balance. The follow-on reconciliation model is: + +``` +AccountBalanceSnapshot +├── account_id +├── as_of +├── balance_minor +├── balance_type: ledger | statement | current | available +├── source +└── import_batch_id | null +``` + +Known adapters should expose opening/closing balance evidence when present. For +an asset account, natural movement equals `signed_minor`; for a liability, +natural movement equals `-signed_minor`. Reconciliation can then verify: + +``` +opening natural balance + natural movements = closing natural balance +``` + +This phase adds the dated opening-balance contract and statement reconciliation +work package. It does not implement every balance snapshot type. + +An import batch binds either an existing `destination_account_id` or a validated +new-account draft. It never binds a name. If the user chooses a new account, the +account and its transactions are created in the same commit transaction so a +discarded preview leaves no orphan account. + +Account names are labels and may repeat. Similar/duplicate names produce a +disambiguation warning, never rejection or identity. Strong duplicate-account +suspicion uses the available tuple `(institution, type, currency, last4)` but +still requires user confirmation; even `last4` is not globally unique. Selection, +imports, and relationships always use account ID. + +### 3.2 Canonical sign convention + +> **PFA's internal amount sign is the economic effect on the account's +> contribution to net worth.** + +| Event | Source text | Canonical | +|---|---|---| +| Salary into current account | `+3,305.00` | `+330500` | +| Debit-card purchase | `-50.00` | `-5000` | +| **AMEX charge** | `+50.00` (debit-positive) | `-5000` (liability up, net worth down) | +| **AMEX payment received** | `1,651.71 CR` | `+165171` (liability down) | +| Bank side of that payment | `-1,651.71` | `-165171` | + +The invariant that makes this worth having: + +``` +HSBC -165171 +AMEX +165171 + ──────── +consolidated 0 +``` + +**Implementation note — this does not require a schema migration.** +PFA stores `amount_minor` as a positive magnitude plus a legacy normalized +`flow_direction` of `"debit"`/`"credit"` (`src/pfa/db/models.py:46`, +`src/pfa/ingestion/service.py:249`). For compatibility, the canonical helper is: + +```python +signed_minor = amount_minor if flow_direction == "credit" else -amount_minor +``` + +No account-nature flip is needed in this expression. This mapping describes +PFA's existing normalized money-in/money-out storage only. It is **not** the +source statement's CR/DR marker and is not a claim about accounting debit/credit +semantics on assets or liabilities. + +Keep three concepts explicit: + +``` +source direction CR / DR / paid in / paid out / source sign +canonical polarity signed_minor > 0 or < 0 +transaction kind expense / income / refund / transfer / fee +``` + +Adapters retain source direction in candidate/import provenance and emit +canonical polarity. Downstream code consumes `signed_minor`, not assumptions +about the words `debit` or `credit`. Put a later storage rename on the roadmap: +`flow_direction` → `canonical_direction` (or `money_in`/`money_out`) once the +migration cost is justified. + +Do **not** migrate to a stored signed `amount_minor`. That is a breaking change +across `src/pfa/analytics/service.py`, `src/pfa/api/app.py:422`, +`src/pfa/cli/app.py:143` and every +fixture, and it buys nothing the helper does not. + +`nature` is for balances and net worth, not for transaction signs. Keep the two +concepts separate. + +### 3.3 Statement content selects the adapter; account type validates it + +Three distinct pieces of information — do not collapse them: + +``` +CONTENT DETECTOR "which export shape is this?" → amex_uk_csv +ACCOUNT TYPE "what does this account represent?" → credit_card +STATEMENT ADAPTER "what do these columns/signs/dates mean?" → debit_positive +``` + +The current plan's earlier wording contained a contradiction: it keyed adapters +from a bound account, but the UI asks the user to bind an account only after +detection, and the staged upload is deleted after preview. Resolve it as follows: + +- detect a stable `adapter_id` from headers, column geometry, and statement + markers; never from filename, folder, or account name; +- each adapter declares compatible account types, currency evidence, amount + convention, date semantics, and extraction strategy; +- persist `adapter_id`, detection confidence, reason codes, detected institution, + and masked account hint on the import batch; +- account selection validates the detected adapter. It does not choose it; +- an adapter/account mismatch is blocking and explains the conflict. + +`credit_card` must not imply debit-positive. Another card export may write +purchases as `-42.50` and payments as `+500.00`. `AmexUkCsvAdapter` can declare +`(compatible_types={CREDIT_CARD}, debit_positive)` while another card declares +signed values. Downstream code receives canonical semantics only. + +The `amount_sign` dropdown becomes a **fallback for generic/unknown formats +only**. For a recognized adapter it never appears. A low-confidence or ambiguous +detection cannot silently fall through to `GENERIC`; it must block commit until +the user explicitly chooses generic semantics. + +### 3.4 Transaction invariants + +| Event | kind | purpose | account | canonical | spending | income | +|---|---|---|---|---|---|---| +| Card purchase | `EXPENSE` | — | credit_card | `< 0` | ✓ | ✗ | +| Card payment, bank leg | `TRANSFER` | `CREDIT_CARD_PAYMENT` | current | `< 0` | ✗ | ✗ | +| Card payment, card leg | `TRANSFER` | `CREDIT_CARD_PAYMENT` | credit_card | `> 0` | ✗ | ✗ | +| Card refund | `REFUND` | — | credit_card | `> 0` | reduces | ✗ | + +**A positive/CR row on a credit card is not automatically a payment.** + +``` +PAYMENT RECEIVED → TRANSFER / CREDIT_CARD_PAYMENT +PRET REFUND → REFUND +CASHBACK → income/rebate semantics +CHARGEBACK CREDIT → REFUND / adjustment +``` + +> **CR tells us direction, not kind.** Direction comes from the marker; kind +> comes from description rules plus account context. + +`flow_direction` keeps its stored `debit`/`credit` values for compatibility, but +it is documented only as legacy normalized PFA inflow/outflow polarity.

Canonical calculations +use `signed_minor`; UI copy uses “money out” / “money in” or domain labels. + +### 3.5 Import safety and reversibility + +Preview is a trust surface, not a row count.

No “Ready to commit” state is allowed before these checks. + +Every successful commit returns an import receipt and an **Undo import** action. +Undo deletes only transaction IDs recorded by that committed batch plus derived +transfer links/suggestions, in one transaction. It is idempotent and never +deletes the account automatically. + +Do not build a dependency graph for v0.2. If an imported transaction has +`updated_at > batch.committed_at` (or later revision metadata), Undo shows how +many imported rows were edited and requires confirmation. Confirmed Undo deletes +those rows and edits. If an event links transactions from two batches, undoing +one batch removes the event/decision and that batch's leg only; the opposite +transaction remains authoritative. + +### 3.6 Transfer purposes — add only what this slice uses + +Add `CREDIT_CARD_PAYMENT` to the existing `SAVING`, `INVESTMENT`, and `OTHER` +values. Defer `INTERNAL` and `DEBT_PRINCIPAL` until a workflow consumes them. +Adding speculative enum members weakens rather than strengthens the contract. + +A card repayment is liability settlement, not spending. Interest and fees that +appear as separate card rows remain expenses. Loan principal allocation is a +different problem because one loan payment can contain both principal and +interest; do not pretend this phase solves it. + +### 3.7 Cash and debt metrics + +`current_cash` means liquid cash, not net position. Resolve the previous open +question now: + +``` +liquid account types = CURRENT | SAVINGS | CASH +account_cash(as_of) = opening balance at end-of-day baseline + + canonical signed_minor where + opening_balance_as_of < transaction_date <= as_of +current_cash(as_of) = sum(account_cash) only when every included account is known +``` + +If any liquid account lacks a baseline covering `as_of`, the user-facing total +is `unknown/incomplete`, not a confidently partial number. The service result +must carry coverage status and missing account IDs (it may also expose a labeled +known subtotal). Historical cash before the earliest accepted baseline is +unknown. Never sum pre-baseline transactions into a later baseline. + +This includes every transaction kind. A transfer between two imported liquid +accounts nets to zero; a card repayment reduces cash on its bank leg; a card +charge never enters the calculation because the card account is not liquid. +Do not use `_cash_delta(kind)` for this metric. + +Split the old ambiguous debt number: + +| Metric | Exact source | Question answered | +|---|---|---| +| `debt_repayments_minor` | positive canonical card-account legs classified `TRANSFER/CREDIT_CARD_PAYMENT` | How much card liability did I repay? | +| `debt_costs_minor` | `EXPENSE`/`FEE` rows categorized as debt interest/fees | What did debt cost me? | +| `debt_service_minor` | deferred | How much total cash did debt consume? | + +Use the card-side repayment transaction as the metric source so a paired event +does not double count both legs. Pairing changes presentation, not totals. +`DEBT_PAYMENT` temporarily means debt costs only; document that name debt and +plan a later enum migration to `DEBT_COST` or explicit interest/fee categories. + +### 3.8 Accepted transfer events and reviewable suggestions + +Both statement transactions remain authoritative. Linking never merges or +deletes a leg. + +``` +TransferEvent +├── id, purpose, match_method, created_at +└── TransferLeg(event_id, transaction_id, role) # 2+; transaction_id unique + +TransferMatchDecision +├── stable match_key +├── left_transaction_id, right_transaction_id +├── state: suggested | accepted | dismissed +├── confidence, reason_codes, event_id? +└── created_at, reviewed_at +``` + +`role` is explicit domain data, never inferred later from sign: + +```python +class TransferLegRole(StrEnum): + SOURCE = "source" + DESTINATION = "destination" + FEE = "fee" +``` + +Every accepted event has exactly one source, exactly one destination, and zero +or more fee legs. v0.2 validates a negative source and positive destination but +does not derive roles from those signs. Manual cross-currency linking requires +the user/service action to assign roles explicitly. + +Only accepted/high-confidence auto matches create a `TransferEvent`. Decisions +are persisted so a dismissed pair does not reappear on every import. Matching is +idempotent; rerunning it cannot duplicate an event or suggestion. Manual confirm, +dismiss, link, and unlink operations are explicit API actions and audit their +origin. An unlink records suppression so the same automatic pair is not +immediately recreated. + +Cross-currency is a known domain requirement, not a hypothetical one. The event +and leg schema must therefore permit different transaction currencies, unequal +absolute amounts, and an optional fee leg. Do not place same-currency or +equal-amount constraints on `TransferEvent`/`TransferLeg`; those are matcher-v0.2 +rules only. + +Design the Slice D companion now, but create/populate it when manual +cross-currency linking ships: + +``` +TransferFx +├── event_id +├── quoted_rate_decimal | null +├── rate_source: derived | statement | user +└── created_at +``` + +Rate orientation is fixed: **destination currency units per one source currency +unit**. Use `Decimal` major-unit amounts after applying each currency's minor-unit +exponent: + +``` +SOURCE -£1,000 +DESTINATION +₹118,400 +implied rate = 118.4 INR / GBP +``` + +The inverse is returned only when explicitly requested. Fee legs do not enter +the implied-rate numerator or denominator. + +Source/destination currencies and minor-unit amounts come from event legs and +their `role`; `implied_rate` is derived from those legs. Do not duplicate them in +`TransferFx`, where they could drift from authoritative transactions. A fee with +its own transaction is a `role=fee` leg, not both `fee_minor` and a foreign key. +No automatic GBP↔INR matching is part of v0.2. + +The Activity Ledger renders accepted events as one collapsed row expandable to +both original legs. Suggestions remain separate rows with a review prompt; they +must not silently alter presentation or analytics. + +### 3.9 Pairing algorithm + +A candidate pair requires all baseline checks: + +- different active owned accounts and neither transaction already linked; +- one leg on `CREDIT_CARD`, one on `CURRENT`/`SAVINGS`; +- same currency, opposite canonical signs, equal absolute amount; +- dates within ±3 calendar days; +- card leg already classified `CREDIT_CARD_PAYMENT`. + +Baseline checks alone are not enough to auto-link. Auto-link also requires a +strong corroborating cue: a stable shared reference, or a bank description that +names the card institution/account hint. A single weak candidate is still a +suggestion; “only one result” is not confidence. Multiple plausible candidates +are suggestions with `ambiguous_amount_date` reason codes. + +The real corpus case is expected to auto-link because both the card payment rule +and `AMERICAN EXPRESS` bank descriptor corroborate it: + +``` +HSBC/Bank/TransactionHistory.csv 02/09/2025 AMERICAN EXPRESS DD -165171 +AMEX/latest.csv 02/09/2025 PAYMENT RECEIVED - THANK YOU +165171 +``` + +### 3.10 End-to-end import flow + +1.

Return a receipt. +- Add an idempotent undo endpoint/action scoped to committed transaction IDs and + derived transfer records. If imported rows changed later, show the affected + count and require confirmation; do not build a dependency graph. + +**Slice A acceptance:** importing the AMEX CSV to a new credit-card account +shows 34 charges with negative canonical polarity and never as income. The +positive payment row is never inferred as income; until Slice B classifies it, +it is visibly unresolved and blocks or requires explicit user classification. +The preview has no known-format sign control, shows reconciliation evidence when +available, and returns a working Undo import action.

Route advisor questions through capability-based Data, +Spending, Cashflow, Wealth, Investment, Planning, and System toolsets. This is a +separate AI-engineering plan; the current work only exposes stable deterministic +account/import metadata that it can consume. + +**Slice F — Investments.** Add investment accounts, holdings, price snapshots, +NAV providers, FX valuation, and net-worth integration after trusted input and +cross-currency event semantics exist. + +### Existing data + +All 365 rows in `data/pfa.db` sit on `account_id=1` with no record of which +statement they came from beyond `import_batches`.

Account type validates adapter compatibility; it does not determine raw sign. +4. `current_cash` is liquid assets only, includes signed transfer legs, and uses + transactions strictly after each end-of-day balance baseline. Missing or + future baselines make the requested period unknown/incomplete. Net position + is a separate future metric. +5. Both deterministic card-side and evidence-backed bank-side repayments become + `TRANSFER/CREDIT_CARD_PAYMENT`, not spending. An uncorroborated bank descriptor + is unresolved, never a broad automatic transfer rule. +6. Repayment and cost-of-debt metrics stay separate and cannot double count + paired legs. +7. Both transfer legs are preserved. Pairing links, never merges. +8. Canonical sign is economic net-worth effect. `flow_direction` remains a + legacy normalized storage field, not source/accounting debit-credit truth; + downstream code uses `signed_minor`. No signed-amount migration. +9. Weak or ambiguous pairs require review; a sole candidate is not proof. +10. Imports are reversible through a batch receipt; existing data is never + silently rewritten or discarded. +11. Transfer events permit 2+ legs with different currencies and unequal + amounts. Roles are explicit `source`/`destination`/`fee`; FX rate orientation + is destination units per source unit. v0.2 matching remains same-currency/ + two-leg; `TransferFx` ships with manual cross-currency linking in Slice D, + not as an unused table. +12. Opening balances are dated natural account balances. Available/current/ + statement balances remain distinct; known statement balance evidence is + reconciled rather than reduced to row counts. Reconciled means arithmetic + integrity PASS and source-row coverage integrity PASS. +13. Advisor introspection/tool routing is Slice E. This work exposes stable + deterministic metadata but does not expand into AI behavior. + +## 8. Product acceptance gate + +The slice is usable only when a non-technical user can complete this sequence +without knowing accounting terminology: + +1. Upload a recognized AMEX statement. +2. Understand why PFA suggests a credit-card account. +3. Create or select that account and see the sanity box: statement period, + purchases, payment, income, unresolved rows, PFA spending/repayment effects, + and reconciliation status before commit. +4. Commit, see a receipt, and undo it safely; edited imported rows produce a + clear count and confirmation rather than a dependency-graph workflow. +5. Import the matching bank statement and understand whether PFA linked the + payment automatically or needs confirmation. +6. See spending, income, liquid cash, repayment, and debt-cost totals remain + consistent before and after linking. If a requested cash period predates a + known baseline, see “historical balance unavailable/incomplete” rather than a + fabricated total. + +Failure copy names the problem and next action. No raw `debit`/`credit`, adapter +class name, stack trace, or silent fallback is exposed as user guidance. diff --git a/docs/plans/2026-09-05-post-v0.2-handoff.md b/docs/plans/2026-09-05-post-v0.2-handoff.md new file mode 100644 index 0000000..9bc9bf9 --- /dev/null +++ b/docs/plans/2026-09-05-post-v0.2-handoff.md @@ -0,0 +1,68 @@ +# Post-v0.2 handoff — remaining major issues + +Written 2026-09-05, after tagging `v0.2.0`.

A new user sees “Extracting candidates” and “Successfully Imported” before selecting a file; keyboard focus reaches fake receipt links. Immediate trust failure. | Hidden elements have no layout, accessibility-tree presence, or tab stops. Add fresh-load browser regression test. | +| IMP-02 | P0 | Generic import bypasses stable account binding | HSBC CSV preview had no explicit destination/new-account binding, then committed 30 rows and created a GBP account with missing institution metadata. This violates the parent binding contract and risks silent cross-account contamination. | Every staged commit supplies exactly one explicit, validated binding. Generic fallback cannot auto-create an account. | +| IMP-03 | P0 | HSBC content can be hijacked by the Amex detector | Four of eight HSBC PDFs selected `amex_uk_pdf` at 0.98 confidence. Detection scans all extracted text and checks broad Amex phrases before HSBC; transaction narrative text can win over statement identity. | Anchor institution evidence to statement header/issuer regions; detect conflicts; reject ambiguity. Verify all eight private samples and redacted fixtures. | +| IMP-04 | P0 | Multi-currency analytics hides real activity | After importing 13 INR transactions, default monthly analytics returned GBP zero values and zero transaction count. INR-scoped API calls returned the real activity. Frontend requests omit currency and money formatting defaults to GBP. Overview therefore showed empty spend while its badge implied 13 items. | Currency/account scope must be explicit and consistent through analytics, categories, UI formatting, budgets, goals, and advisor. No silent GBP fallback. | +| IMP-05 | P0 | Advisor makes unsafe claims from missing data | Advisor reported GBP 0 spending, claimed no transaction history/cash position, and said a purchase was technically affordable based on unused budget while acknowledging missing income, spending, and cash data. Budget headroom is not available cash. | Hard-stop advice when data scope/coverage is incomplete; expose currency and coverage; never infer affordability from a budget alone. Add grounded answer tests. | +| IMP-06 | P0 | Real imports are not practically categorizable | All 13 HDFC transactions arrived uncategorized. Web and API expose no edit workflow. CLI correction is one transaction at a time and creates exact-description rules. Without categories, spending-habit analysis is empty. | Add review queue, single and bulk categorization, rule preview/edit, undo, and immediate analytics refresh. | +| IMP-07 | P0 | Matching Amex PDF and CSV exports disagree | Across four matching periods, valid row counts matched per pair, but normalized comparison found only 49/56, 43/50, 50/65, and 52/63 shared transaction fingerprints. Definitive amount mismatches occurred in three periods and one direction mismatch occurred. PDFs also produced extra invalid candidates. | Cross-format parity fixture must reconcile dates, directions, and minor-unit amounts or block PDF support. | +| IMP-08 | P0 | Assets and net worth are absent | No holdings, valuation, liability, or net-worth endpoints/workflows exist. “Investments” is only an account type/analytic label. The persona cannot optimize assets or see a complete financial position. | Narrow the promise or add holdings, valuations, liabilities, net worth, and data-freshness semantics. | +| IMP-09 | P1 | Encrypted PDF error contract fails | The encrypted HDFC PDF contains encryption markers but returned HTTP 200 with a generic zero-row issue instead of `PDF_PASSWORD_REQUIRED`. Guidance is lost. | Classify encrypted PDFs before generic extraction failure and add this sample shape as a redacted regression fixture. | +| IMP-10 | P1 | Post-commit UI state is stale | Immediately after HDFC commit, API contained 13 transactions while the navigation activity badge remained zero until reload. | Invalidate/reload all derived stores after commit, undo, categorization, budget, and goal mutations. | +| IMP-11 | P1 | Budgets and goals are display-only and currency-blind | No web/API create/edit flow was available; CLI was required. Synthetic budget and goal then rendered with GBP symbols despite the HDFC account being INR. Goal progress remained zero with no usable update path. | Add currency-aware CRUD, contribution/progress semantics, and validation against selected accounts. | +| IMP-12 | P1 | Empty-state copy fabricates insight | Fresh database used narrative language such as spending “movement” and month-over-month change despite having no data. False precision makes the product look unreliable. | Use explicit no-data/partial-data states and state the action needed to unlock analysis. | +| IMP-13 | P1 | Migration metadata has drifted | `alembic check` proposes removal of two transfer-decision indexes. A clean schema is not at migration parity. | Resolve model/migration index ownership; require `alembic check` in CI. | +| IMP-14 | P2 | Mobile layout is technically contained but not mobile-shaped | At 390×844 there was no horizontal overflow, but the full sidebar remained and 11 of 13 interactive targets were below 44 px. | Responsive navigation and minimum target-size pass at phone widths. | +| IMP-15 | P2 | Accessibility polish remains | Lighthouse accessibility 96: 21 contrast failures and one accessible-name mismatch. Hidden fake states create a more severe keyboard issue than the score reflects. | Zero hidden-state focus, WCAG AA contrast, matching visible/accessibility names. | +| IMP-16 | P2 | Transfer capability lacks an obvious user journey | Backend transfer-suggestion endpoints exist, but no visible review surface was found. A single-account corpus cannot validate matching quality. | Add discoverable review/accept/reject UX and test with redacted cross-account transfer fixtures. | +| IMP-17 | P2 | Browser regression coverage is missing | No browser/E2E test suite was found. Unit/API gates stayed green while fresh-load UI and multi-currency journeys were broken. | Cover fresh load, upload, binding, commit, duplicate, categorization, analytics, advisor, and undo in a browser gate. | + +## User-journey critique + +### 1. “Import all my accounts safely” — fails + +HDFC Delimited provides a trustworthy example: high-confidence issuer/format label, explicit account/currency confirmation, exact balance reconciliation, duplicate handling, and guarded undo. The same safety model is not universal. Generic HSBC CSV can commit without binding, HSBC PDFs can be assigned to another bank, and encrypted PDF guidance is wrong. + +### 2. “Show where my spending is bad” — fails + +The imported HDFC activity is invisible to default GBP analytics and remains uncategorized. Category views cannot answer which habits are costly, recurring, avoidable, or worsening. The UI cannot correct the data. A count of transactions is not an insight. + +### 3. “Help me save more” — fails + +Budgets and goals require CLI setup, lack coherent currency/account context, and do not connect to categorized behavior. No workflow converts a goal into a contribution plan, identifies realistic cuts, or shows confidence/coverage. The advisor compounds this by confusing budget headroom with affordability. + +### 4. “Optimize my cash and assets” — fails + +There is no complete balance-sheet model: no holdings, valuation dates, liabilities, debt costs, net worth, asset allocation, or opportunity-cost comparison. Cash analytics alone cannot support asset optimization. + +### 5. “Trust this with financial data” — mixed + +Local-only operation, explicit HDFC binding, reconciliation, duplicate detection, and undo are strong foundations. False fresh-load success, wrong-bank detection, silent currency fallback, and unsupported advisor conclusions negate that trust. + +## Heuristic review + +Single-context review; parallel reviewers were not permitted for this run. + +| Nielsen heuristic | Score / 4 | Assessment | +|---|---:|---| +| Visibility of system status | 0 | Fabricated progress/success, stale post-commit counts. | +| Match with the real world | 1 | Currency and affordability semantics conflict with real financial reasoning. | +| User control and freedom | 2 | Undo is strong; correction and setup controls are absent. | +| Consistency and standards | 1 | HDFC binding safeguards do not apply consistently to generic imports. | +| Error prevention | 1 | HDFC guards well; generic commit and detector ambiguity are dangerous. | +| Recognition rather than recall | 2 | Preview metadata helps, but essential account/currency context disappears downstream. | +| Flexibility and efficiency | 1 | No bulk categorization or professional review workflow. | +| Aesthetic and minimalist design | 3 | Visually authored and restrained; false content damages clarity. | +| Error recovery | 2 | Undo/format guidance are useful; encrypted-PDF and parser failures lack actionable recovery. | +| Help and documentation | 1 | Delimited guidance is good; coverage, currency, and advice limitations are not explained. | +| **Total** | **14 / 40** | Attractive shell; low functional trust. | + +**Design-specificity verdict:** the visual system feels intentionally designed rather than generic.
