A detailed (by-security) account can now import its positions from a CSV
instead of adding each security one by one. An "Import CSV" button next to
"Add a title" opens a native picker; the delimiter, encoding and columns
(symbol, quantity, optional price + book_cost) are auto-detected via new
csvAutoDetect helpers and adjustable in a small mapping editor. Rows sharing
a symbol are merged (SUM qty + book_cost, first price) and the batch is merged
into the basket by normalized symbol, so no UNIQUE(snapshot_line_id,
security_id) violation can occur at save. A CSV without a price column imports
quantities with an empty unit_price (fetch/type later) — the existing atomic
save path is unchanged (no SQL/Rust change).

Decouple the /balance empty-state guard into three explicit states via a
new pure helper `deriveLandingState` (empty / accounts-no-snapshot /
populated). Having accounts but no snapshot no longer strands the user on a
snapshot-only onboarding card: each state now renders navigation tiles
(HubReportNavCard, modeled on the Reports hub), and "Manage accounts"
(/balance/accounts) is reachable in every state, including the populated
dashboard.
- Remove BalanceOnboardingCard (component + test) and the dead
balance.onboarding.* i18n keys; add balanceLanding.ts + test.
- Add balance.hub.* and balance.landing.* keys in FR and EN.
- CHANGELOG (EN + FR) under [Unreleased].
Resolves#244
Database lock (the reported 0.10.0 regression):
- tauri-plugin-sql loads SQLite through a default multi-connection sqlx pool
(Pool::connect => max_connections = 10) and exposes no JS transaction
primitive. BEGIN and COMMIT issued as separate db.execute calls could land on
different pooled connections, stranding an open write transaction on an idle
connection — a permanent write lock until app restart. Triggered when the
Bilan page's concurrent reads interleaved with an in-flight snapshot save.
- Fix: funnel every db operation through one FIFO lock in db.ts; withTransaction
holds it across the whole BEGIN..COMMIT so a transaction's statements never
span connections (and the saves become genuinely atomic). A reentrancy guard
lets nested getDb() calls run directly instead of deadlocking. Applied to all
5 transaction sites (saveSnapshotAtomic, upsertSnapshotLines,
proposeStarterAccounts, applyKeywordWithReassignment, applyMigration) via
in-place helper extraction. New db.test.ts covers serialization,
cross-transaction non-interleaving, reentrancy, and lock release on error.
Log console (Settings -> Systems -> Journaux):
- getLogs returned the same mutated array reference, so useSyncExternalStore
(identity comparison) never re-rendered on a new log -> the console never
updated live. getLogs now returns an immutable snapshot rebuilt on each
mutation (stable between mutations, new identity after each).
- Add logInfo/logWarn/logError app-logging API and instrument the snapshot save
(info on success, error on failure) so DB issues surface in the console.
tsc + 635 vitest + vite build green.

Adds a light confirmation modal (DetailAccountWizard) that flips a simple
balance account to detailed entry mode: sets kind='detailed' and
detailed_since = today (local civil day, YYYY-MM-DD) via updateBalanceAccount.
Toggle-only — no title capture; per-security holdings are entered at the next
normal snapshot, where validateDetailedSnapshot requires them from the pivot on.
Entry point: a 'Détailler en titres' action in the per-row actions menu of
BalanceAccountsTable, shown only for kind==='simple' rows (replaces the disabled
'Détail / coming soon' placeholder). Past aggregated history stays frozen
read-only. The flip is one-way: the #212 service backstop rejects
detailed -> simple once holdings exist, and the UI exposes no inverse action.
Exports buildDetailToggleInput() as a pure helper for a focused unit test
(project has no jsdom harness). FR/EN i18n under balance.detailWizard.*; removed
the now-dead balance.overview.detailAction / detailComingSoon keys.

Surface unrealized (latent) gain on the existing balance surfaces, no new
visualization (decision 2026-06-04).
Service:
- AccountLatestSnapshot gains account `kind` + `latest_snapshot_line_id`, so
the table knows which rows are detailed and where their holdings live.
- getAccountLatentGainByLine(lineId) folds a line's holdings through the
existing computeUnrealizedGain (shares the book_cost=0 / NULL -> N/A guard).
- rollupLatentGain(accounts): pure aggregation by asset class, by envelope
(vehicle_type, 'none' bucket), and grand total; per-bucket % denominator is
the known book_cost only (null when none), mirroring the aggregate guard.
Hook (useBalanceOverview):
- Prefetches per-detailed-account latent gain in parallel (failures isolated),
exposes latentGainByAccount + latentGainRollup. Simple accounts skipped.
UI:
- BalanceAccountsTable: expandable detailed rows -> per-security value + latent
gain %; a latent-gain column (shown only when a detailed account has one);
a summary block aggregating latent gain by asset class / envelope.
- BalanceOverviewCard: total latent gain line (hidden without detailed accounts).
- N/A rendered (never divide-by-zero) when book_cost is NULL or 0; partial-%
flag when some positions lack a cost basis.
Native non-CAD currency display de-scoped this round (untestable while all
securities are CAD). Modified Dietz return columns (#204) unchanged.
i18n: balance.latentGain.* in FR + EN. Focused unit tests for
getAccountLatentGainByLine and rollupLatentGain (grouping, 'none' envelope,
null-% / unknown book_cost, empty).

Turn the detailed-account snapshot variant into the real per-title entry
surface (building on the minimal sub-rows from #213):
- New SecurityPicker (src/components/balance/SecurityPicker.tsx): an
autocomplete combobox over the existing balance_securities catalogue
(loaded via listSecurities()) with inline creation. Accepts any
normalized symbol (UPPER/TRIM) with NO live ticker validation — the
price fetch is best-effort and separate. On pick/create it emits a
SecurityPick {symbol, asset_type, name, isNew}; a stock/crypto toggle
lets the user set the asset class when creating a new symbol (default
'stock'). Built on the CategoryCombobox UI idiom (ARIA listbox,
keyboard nav, click-outside). Pure helpers filterSecurities /
decideCreateOption are exported and unit-tested (no jsdom harness).
- SnapshotLineRow detailed sub-rows: labeled columns
[title (SecurityPicker), quantity, price (+ existing PriceFetchControl),
value (qty x price, read-only), book_cost, live unrealized gain].
Account value = displayed SUM of positions. Simple accounts unchanged.
- useSnapshotEditor: new SET_HOLDING_SECURITY action + setHoldingSecurity
callback (atomically sets symbol + asset_type + name and drops the
stale fetched-price attribution since the symbol changed). The
securities catalogue is loaded in loadForDate and exposed as
state.securities, so it refreshes after a save that creates a security.
- i18n: extended balance.snapshot.detailed.* (col.*, picker.*, book cost,
unrealized gain) in FR + EN — no hardcoded UI text.
- CHANGELOG (EN + FR) under [Unreleased]: first user-visible surface of
the per-title detail chain (#210-#213 were schema/service/reducer).
Build (tsc + vite) green; npm test green (613 tests, +10 SecurityPicker).

Structural rewrite of useSnapshotEditor for N holdings per detailed account,
and switch ALL simple/detailed dispatch from category_kind to the account's
own kind. This is the state/plumbing layer; the full multi-security entry UI
(SecurityPicker, rich sub-rows) lands in #214. Simple accounts behave
identically.
Reducer state shape:
- values: Record<accountId, string> (simple accounts, scalar)
- holdings: Record<accountId, HoldingDraft[]> (detailed accounts, one per title)
HoldingDraft is a string-typed, editable mirror of SnapshotHoldingInput with a
stable client-side rowId for React keys. Actions: ADD_HOLDING / REMOVE_HOLDING /
SET_HOLDING_FIELD (plus existing SET_VALUE/PREFILL/RESET). The legacy priced
scalar path (SET_PRICED_FIELD / pricedValues) is removed: after migration v16
(#211) every former-priced account is kind='detailed' with one holding, so those
accounts flow through the holdings path.
Dispatch:
- LOADED hydrates detailed baskets via listHoldingsBySnapshotLine (edit) keeping
the saved price, or getHoldingsForLatestSnapshot (new) dropping the price
(qty-0 excluded server-side). Simple accounts keep the scalar value path.
- SnapshotLineRow / SnapshotEditor / AccountForm now gate on account.kind, not
category_kind. category.kind survives ONLY as the suggested seed default for a
NEW account in AccountForm.
Save: detailed accounts pass their holdings array into SnapshotLineInput.holdings
(presence marks the line detailed; value = rounded-cent SUM); simple accounts
pass a scalar value with no holdings. Blank holding rows are skipped; a partial
row throws a typed error before any DB mutation.
AccountForm: adds an entry-mode selector (defaulting to the category-mapped
kind). New accounts persist as 'simple' (CreateBalanceAccountInput carries no
kind, and the service is out of this issue's scope); converting a fresh account
to detailed + pivot date is #215. Editing locks the selector for an already-
detailed account (the detailed->simple downgrade is service-guarded).
Tests: 19 new reducer/helper unit tests (pure exports; the project has no
renderHook harness) covering ADD/REMOVE/SET_HOLDING_FIELD, LOADED-vs-PREFILL
hydration (price drop, book_cost), qty-0 already excluded upstream, the
build*Lines save builders, and the dispatch-on-account.kind regression
(detailed account under a 'simple' category).
Resolves#213.

Issue 3 of overnight-2026-06-01-bilan-axe-vehicule. Builds the tracking UI
on top of the merged data layer (#202) and input UI (#203).
- Service: getSnapshotTotalsByVehicleAndDate(range) mirrors the by-category
aggregation with GROUP BY COALESCE(a.vehicle_type, 'none') so null-envelope
accounts land in a single 'none' bucket (never a SQL NULL key). Add
vehicle_type to getAccountsLatestSnapshot SELECT + type.
- useBalanceOverview: new groupAxis ('class'|'vehicle') state ORTHOGONAL to
chartMode; loads byVehicle alongside byCategory. Default groupAxis='class'.
- BalanceEvolutionChart + BalancePage: stacked-mode sub-toggle 'Par classe
d'actif' (default) / 'Par enveloppe'. Vehicle legend reuses the #203
vehicleType.* labels; the 'none' bucket uses balance.vehicle.none.
- BalanceAccountsTable: 4 return columns collapsed by default with a toggle,
persisted across sessions via userPreferenceService key balance_show_returns.
- i18n FR/EN: balance.chart.axis.{byAssetClass,byVehicle}, balance.vehicle.none,
balance.accountsTable.toggleReturns.{show,hide} (+ axisLegend aria label).
Tests: npm run build green (0 type errors); vitest 3314 passed. Added 5
service tests for the 'none' bucket + mixed envelopes + date range.

The internal Step component received `t: TFunction` as a prop while every
other component in the codebase calls useTranslation() directly at the
top of the function. Aligns with the majority pattern.
Suggestion S5 from PR #184 review (#187).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds defense-in-depth: each iteration runs a SELECT COUNT(*) WHERE name=?
AND balance_category_id=? AND archived_at IS NULL inside the BEGIN/COMMIT
block, immediately before its INSERT. On a hit, the iteration skips the
INSERT silently and the returned ids array excludes the skipped starter.
Rationale: balance_accounts has no UNIQUE constraint on (name, category)
and the upstream pre-filter (getStarterCollisions) is best-effort. If a
race or a bypass slips a duplicate through, the in-txn check catches it
without surfacing a confusing error to the user.
Existing two tests in StarterAccountsModal.test.tsx updated to mock the
new SELECT call sequence; new test "skips silently when in-txn collision
check finds an existing account" added.
Suggestion S3 from PR #185 review (#187).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
getStarterCollisions now filters `archived_at IS NULL` so a starter
account the user voluntarily archived no longer blocks re-creation
through the StarterAccountsModal. Matches the rest-of-codebase
convention (active = is_active=1 AND archived_at IS NULL).
Suggestion S4 from PR #185 review (#187).

Extends PR #189's fix (one input on /balance/snapshot) to the 7 remaining
native <input type="date"> fields across 4 components:
- transactions/TransactionFilterBar.tsx (dateFrom + dateTo)
- adjustments/AdjustmentForm.tsx (form.date)
- balance/LinkTransfersModal.tsx (from + to)
- dashboard/PeriodSelector.tsx (localFrom + localTo)
Each onChange handler now calls e.currentTarget.blur() after the state
update to dismiss the native date popup on Linux Tauri WebView. The call
is a no-op on Windows WebView2 / macOS WKWebView, where the picker
already auto-closes.
No automated test added: this is a WebKitGTK-specific WebView quirk that
cannot be reproduced in jsdom/vitest. Manual smoke test on Linux Tauri
dev was the validation, mirroring PR #189's approach.

Part 1 — New profiles: seed 4 starter accounts in
consolidated_schema.sql (Compte chèque/CELI/REER/Compte
non-enregistré, currency CAD, is_active=1) right after the
balance_categories seeds. Categories resolved via SELECT subquery
on the seeded `key` values for robustness.
Part 2 — Existing profiles: StarterAccountsModal proposes the same
4 starters at first /balance visit. Default-checked checkboxes,
collision rule (case-insensitive trim name + matching category)
disables matches with a "Déjà présent" tooltip. The atomic helper
`proposeStarterAccounts` wraps the inserts in BEGIN/COMMIT (rolls
back on error). user_preferences.balance_starter_proposed records
{shown_at, accepted} so the modal never reappears, dismissed or
confirmed.
Part 3 — docs/adr/0012-balance-two-level-model.md (Proposed):
captures the future vehicles × compositions model for reflection,
no code change. Numbered 0012 because 0011 was already taken by
the providers-best-effort-yahoo ADR. Linked from architecture.md
ADR table and Bilan section.
Tests: StarterAccountsModal.test.tsx covers STARTER_ACCOUNTS shape,
getStarterCollisions (case-insensitive trim, category-scoped) and
proposeStarterAccounts (insert order, COMMIT, ROLLBACK on failure).
No render tests — mirrors the BalanceOnboardingCard pattern (no
jsdom configured).
Resolves#179
Replace empty BalanceOverviewCard with BalanceOnboardingCard showing
two steps:
1. Create an account
2. Enter a snapshot
Step 2 is grayed out until at least one account exists; the entire
card is replaced by BalanceOverviewCard once a snapshot is recorded.
Hide "+ New snapshot" button when 0 accounts (it lives inside the
overview card, which is now hidden in that state).
Improve SnapshotEditPage noAccounts copy to clarify account vs
snapshot semantics.
Resolves#178
Priced balance categories now carry an explicit `asset_type`
('stock' | 'crypto') so PriceFetchControl can route to the right
provider without symbol heuristics. ETH = Ethan Allen NYSE AND
Ethereum crypto are no longer ambiguous.
Migration v10 adds a nullable column and backfills the two seeded
priced categories (key='stock','crypto'). Legacy custom priced rows
stay NULL until the user edits the category — SnapshotLineRow hides
the price-fetch button when asset_type is NULL on a priced row, so
manual entry remains available.
Service-side validation rejects priced creation without asset_type
('asset_type_required') and rejects values outside ('stock','crypto')
('asset_type_invalid'). Simple kind coerces asset_type to NULL.
The CategoryVariant of AccountForm shows the selector only when
kind=priced, requires it on submit, and resets it on kind switch.
i18n keys added under balance.category.assetType.* (FR + EN).
Tests:
- 4 new Rust migration tests in lib.rs (column add, seed backfill,
legacy row stays NULL, CHECK rejects 'gold')
- 6 new vitest cases on createBalanceCategory + listBalanceAccounts
asserts c.asset_type AS category_asset_type in the join
- balance-flow integration test updated to pass asset_type='stock'
No new test for SnapshotLineRow render guard — project lacks
@testing-library/react + jsdom; the guard is one boolean expression
covered by manual QA per autopilot decisions in PR #167.
Fixes#169
- New component renders button + consent modal + spinner + attribution
- Best-effort warning shown once per session for stock categories
- Hidden if not premium or category kind != 'priced'
- Consent persisted per-profile in user_preferences.price_fetching_consent
- Manual unit_price input remains active in all paths
- 17 vitest tests (no RTL/jsdom — logged MEDIUM in decisions-log.md)
- Wired into SnapshotLineRow/SnapshotEditor/SnapshotEditPage
- asset_type hardcoded to 'stock' pending category schema extension (MEDIUM)
Closes#158
Issue #142 / Bilan #4 — vertical reference lines for tagged transfers.
`BalanceEvolutionChart.tsx` accepts a new optional prop
`transferMarkers?: BalanceAccountTransferWithTransaction[]`. For every
marker whose `transaction_date` matches a date already on the X axis,
the chart renders a `<ReferenceLine>` (Recharts) — green for `in`
(capital added), red for `out` (capital removed). The marker is drawn
in both `line` and `stacked` modes; in line mode an inline label
("In" / "Out") sits at the top-right of the marker so the user can
identify the direction without hovering.
Markers whose date is between two snapshot ticks are filtered out
(Recharts categorical axis silently drops unknown ticks; preferred
over an off-axis bug). A future improvement is to switch the X axis
to a numeric/time scale so markers can land anywhere — out of scope
here per the autopilot prompt's "least invasive" guideline.

Issue #142 / Bilan #4 — UI for transfer linking + per-account returns.
- New `LinkTransfersModal.tsx`: portal modal with date-range / category /
free-text filters, multi-select with auto-proposed direction (`in` for
negative bank amounts, `out` for positive — flippable per row).
Submits via sequential `linkTransfer` calls; reports per-row failures
inline (most common case: `transfer_already_linked` on a re-submit).
- `BalanceAccountsTable.tsx`: 4 new columns rendered side-by-side —
3M / 1A / Since-inception (Modified Dietz via `compute_account_return`)
+ Unadjusted (`(V_end - V_start) / V_start`). Returns load lazily
after mount via `Promise.all` over (account × horizon); per-cell
failure leaves the slot at "—" without blocking the rest of the
table. The actions menu gains a *Link transfers* item that bubbles
the request up to the parent page. New props:
`sinceCreationDate` (anchors the since-inception horizon) and
`onLinkTransfers` (modal opener).
- `BalancePage.tsx`: hosts the new modal, loads the categories list
once on mount for the filter dropdown, fetches the union of
`listAccountTransfers` per account so the chart can render markers,
and threads the earliest snapshot date down to the table. Reload
is triggered after the modal reports at least one successful link.
- `balance.service.ts`: dropped the unused `BalanceAccountTransfer`
import to satisfy `tsc --noUnusedLocals`.
`npm run build` clean. `npm test` → 429 passed. Manual sanity check:
the table renders "…" placeholders during the per-row return load,
then resolves to either a percentage or a "—" with the partial
tooltip when the underlying snapshot endpoint is missing.

Three new components composed under a new BalancePage at /balance:
- BalanceOverviewCard — latest aggregate net worth, Δ% vs the
previous chronological snapshot (rendered as "—" when only
one snapshot exists), 60-day staleness warning, and a
"+ Nouveau snapshot" CTA pointing at /balance/snapshot.
- BalanceEvolutionChart — Recharts-based line / stacked-area
toggle. Line mode plots SUM(value) per snapshot_date with a
single primary-coloured stroke. Stacked mode transposes the
byCategory series into one Area per category_key with a
fixed 10-color palette indexed deterministically. Tooltip
formats CAD via Intl.NumberFormat.
- BalanceAccountsTable — one row per active account with name,
category label, latest value, and Δ% over the active period
(latest_value vs the period anchor). Returns columns
(3M / 1Y / since-creation / unadjusted) reserved for #142
with a TODO marker. Action menu includes a disabled "Detail"
placeholder + functional "Archive" wired through reload().
BalancePage composes the three with an inline period selector
(3M / 6M / 1A / 3A / Tout) and chart-mode toggle, both styled
as segmented controls. State flows through useBalanceOverview.
Route /balance registered before /balance/accounts in App.tsx.

New scoped useReducer hook covering the full single-snapshot lifecycle —
LOAD_FOR_DATE / SET_LINE_VALUE / SAVE / DELETE / PREFILL_FROM_PREVIOUS /
RESET — with the following semantics:
- 'new' mode (?date= absent or no snapshot at that date) creates the row
at save time only, so abandoning the form does not leave an empty
snapshot behind;
- 'edit' mode loads existing lines + prefills the values map;
- prefillFromPrevious copies simple-kind values from the most recent
earlier snapshot (priced branch is a no-op + TODO Issue #140);
- save() flips 'new' -> 'edit' on success and updates the URL ?date=
so refresh keeps the user in edit mode;
- snapshotDate is immutable in edit mode (UI guard, matches spec).
New SnapshotEditPage at /balance/snapshot:
- date picker (native input type=date — matches the AdjustmentForm /
TransactionFilterBar / PeriodSelector pattern, no new dep)
- per-category groups of accounts with one value field each
- prefill button (disabled when no earlier snapshot exists, with
tooltip explaining why)
- delete button with double-confirmation modal that requires retyping
the snapshot date before the destructive action enables.
New SnapshotEditor (groups by category sort_order) and SnapshotLineRow
(simple variant — single value field per account) components.
Route /balance/snapshot wired in App.tsx.

Wires the AccountsPage end-to-end with a new scoped useReducer hook,
the page itself (accessible at /balance/accounts) and the account form.
useBalanceAccounts (src/hooks/useBalanceAccounts.ts):
- Loads accounts (excludes archived by default) + categories in parallel
- Surfaces typed errors from balance.service via state.errorCode so the
UI can localize them (e.g. seed protection, currency rejection)
- CRUD operations on both domains: addAccount/editAccount/archive/
unarchiveAccount + addCategory/editCategory/removeCategory
AccountsPage (src/pages/AccountsPage.tsx):
- Two tabs: Comptes + Catégories
- Accounts tab: archive toggle, table of (name, category, symbol,
currency, status), inline edit/archive/restore
- Categories tab: full list of seeded + user categories. Add new
simple-kind category (priced creation lands in #140). Rename via
inline prompt; delete disabled on seeded rows. Errors surfaced via
i18n keys keyed on BalanceErrorCode.
AccountForm (src/components/balance/AccountForm.tsx):
- Variant=account only (category variant lands in #140)
- Auto-detects priced category to hint the symbol field
- Full FR/EN coverage of labels and validation messages
Per spec-plan-bilan.md v2 the sidebar entry "Bilan" is intentionally
not added in this issue — it lands in #141 (Bilan #3) when the
/balance overview becomes navigable. Until then the route is reachable
directly via URL.
