# Changelog

## [Unreleased]

### Added
- **Cartes report — Monthly / YTD toggle** (`/reports/cartes`): new segmented toggle next to the reference-month picker flips the four KPI cards (income, expenses, net balance, savings rate) between the reference-month value (unchanged default) and a Year-to-Date cumulative view. In YTD mode, the "current" value sums January → reference month, MoM delta compares it to the same-year Jan → (refMonth − 1) window (null for January), YoY delta compares it to Jan → refMonth of the previous year, and the savings rate uses the YTD income/expenses. The 13-month sparkline, top movers, seasonality and budget adherence cards remain monthly regardless of the toggle. The savings-rate tooltip now reflects the active mode. Choice persisted in `localStorage` (`reports-cartes-period-mode`) (#102)
- **User guide — Cartes section**: new dedicated section documenting the four KPI formulas, the Monthly/YTD toggle, the sparkline, top movers, seasonality and budget adherence rules, along with the savings-rate edge case ("—" when income is zero) (#102)
- **Cartes report**: help tooltip on the savings-rate KPI explaining the formula — `(income − expenses) ÷ income × 100`, computed on the reference month (#101)
- **Trends report — by category** (`/reports/trends`): new segmented toggle to switch the category-evolution chart between stacked bars (default, unchanged) and a Recharts stacked-area view (`<AreaChart stackId="1">`) that shows total composition over time. Both modes share the same category palette and SVG grayscale patterns. The chosen type is persisted in `localStorage` (`reports-trends-category-charttype`) (#105)

### Changed
- **Category zoom report** (`/reports/category`): the category picker is now a typeable, searchable combobox with accent-insensitive matching, keyboard navigation (↑/↓/Enter/Esc) and hierarchy indentation, replacing the native `<select>` (#103)
- **Compare report — Actual vs. actual** (`/reports/compare`): the table now mirrors the rich 8-column structure of the Actual vs. budget table, splitting each comparison into a *Monthly* block (reference month vs. comparison month) and a *Cumulative YTD* block (progress through the reference month vs. progress through the previous window). MoM cumulative-previous uses Jan → end-of-previous-month of the same year; YoY cumulative-previous uses Jan → same-month of the previous year. The chart remains a monthly-only view (#104)
- **Highlights report** (`/reports/highlights`): the monthly tiles (current-month balance, top movers vs. previous month) now default to the **previous calendar month** instead of the current one, matching the Cartes and Compare reports. The YTD tile stays pinned to Jan 1st of the current civil year. A new reference-month picker lets you pivot both the monthly balance and the top-movers comparison to any past month; the selection is persisted in the URL via `?refY=YYYY&refM=MM` so the view is bookmarkable. The hub highlights panel follows the same default (#106)

### Fixed
- **Cartes report**: removed the non-functional period selector — the Cartes report is a "month X vs X-1 vs X-12" snapshot, so only the reference-month picker is needed (#101)
- **Cartes report**: savings-rate KPI now shows "—" instead of "0 %" when the reference month has no income (division by zero is undefined, not zero) (#101)
- **Cartes report — budget adherence**: the card was always saying "no budgeted categories this month" even when budgets were defined on expense categories. Root cause: expense budgets are stored signed-negative, and the filter/comparison used raw values instead of absolutes. Categories, in-target counts, and worst-overrun amounts are now all computed on absolute values (#112)

## [0.8.2] - 2026-04-17

### Added
- **Feedback Hub widget** (Settings → Logs): a *Send feedback* button in the Logs card opens a dialog to submit suggestions, comments, or bug reports to the central Feedback Hub. A one-time consent prompt explains that submission reaches `feedback.lacompagniemaximus.com` — an explicit exception to the app's 100% local operation. Three opt-in checkboxes (all unchecked by default): include navigation context (page, theme, viewport, app version, OS), include recent error logs, identify with your Maximus account. Routed through a Rust-side command so nothing is sent unless you press *Send* (#67)
- **Cartes report** (`/reports/cartes`): new dashboard-style sub-report in the Reports hub. Combines four KPI cards (income, expenses, net balance, savings rate) showing MoM and YoY deltas simultaneously with a 13-month sparkline highlighting the reference month, a 12-month income vs. expenses overlay chart (bars + net balance line), top 5 category increases and top 5 decreases vs. the previous month, a budget-adherence card (N/M on-target plus the three worst overruns with progress bars), and a seasonality card that compares the reference month against the same calendar month from the two previous years. All data comes from a single `getCartesSnapshot()` service call that runs its queries concurrently (#97)

### Changed
- **Compare report** (`/reports/compare`): reduced from three tabs (MoM / YoY / Budget) to two modes (Actual vs. actual / Actual vs. budget). The actual-vs-actual view now has an explicit reference-month dropdown in the header (defaults to the previous month), a MoM ↔ YoY sub-toggle, and a grouped side-by-side bar chart (two bars per category: reference period vs. comparison period). The URL `PeriodSelector` stays in sync with the reference month picker (#96)

## [0.8.0] - 2026-04-14

### Added
- **Reports hub**: `/reports` is now a hub surfacing a live highlights panel (current month + YTD net balance with sparklines, top movers vs. last month, top recent transactions) and four navigation cards to dedicated sub-reports (#69–#76)
- **Highlights report** (`/reports/highlights`): balance tiles with 12-month sparklines, sortable top movers table, diverging bar chart, recent transactions list with 30/60/90 day window toggle (#71)
- **Trends report** (`/reports/trends`): internal sub-view toggle between global flow (income vs. expenses) and by-category evolution, chart/table toggle on both (#72)
- **Compare report** (`/reports/compare`): tab bar for Month vs. Previous Month, Year vs. Previous Year, and Actual vs. Budget; diverging bar chart centered on zero for the first two modes (#73)
- **Category zoom** (`/reports/category`): single-category drill-down with donut chart of subcategory breakdown, monthly evolution area chart, and filterable transactions table (#74)
- **Contextual keyword editing**: right-click any transaction row to add its description as a categorization keyword; a preview dialog shows every transaction that would be recategorized (capped at 50, with an opt-in checkbox for N+) before you confirm. Available on the category zoom, the highlights list, and the main transactions page (#74, #75)
- **Bookmarkable period**: the reports period now lives in the URL (`?from=YYYY-MM-DD&to=YYYY-MM-DD`), so you can copy, paste, and share the link and keep the same state (#70)
- **View mode preference** (chart vs. table) is now persisted in `localStorage` per report section

### Changed
- The legacy monolithic `useReports` hook has been split into per-domain hooks (`useReportsPeriod`, `useHighlights`, `useTrends`, `useCompare`, `useCategoryZoom`) so every sub-report owns only the state it needs (#70)
- Context menu on reports (right-click) is now a generic `ContextMenu` shell reused by the existing chart menu and the new keyword dialog (#69)

### Removed
- The dynamic pivot table report was removed. Over 90% of its real usage was zooming into a single category, which is better served by the new Category Zoom report. Git history preserves the old implementation if it ever needs to come back (#69)

### Security
- New `AddKeywordDialog` enforces a 2–64 character length bound on user keywords to prevent ReDoS on large transaction sets (CWE-1333), uses parameterized `LIKE` queries for the preview (CWE-89), wraps its INSERT + per-transaction UPDATEs in an explicit BEGIN/COMMIT/ROLLBACK transaction (CWE-662), renders all untrusted descriptions as React children (CWE-79), and recategorizes only the rows the user explicitly checked — never retroactively. Keyword reassignment across categories requires an explicit confirmation step (#74)
- `getCategoryZoom` walks the category tree through a **bounded** recursive CTE (`WHERE depth < 5`), protecting against malformed `parent_id` cycles (CWE-835) (#74)

## [0.7.4] - 2026-04-14

### Changed
- OAuth tokens are now stored in the OS keychain (Credential Manager on Windows, Secret Service on Linux) instead of a plaintext JSON file. Existing users are migrated transparently on the next sign-in refresh; the old file is zeroed and removed. A "tokens stored in plaintext fallback" banner appears in Settings if the keychain is unavailable (#66, #78, #79, #81)
- Cached account info is now HMAC-signed with a keychain-stored key: writing `subscription_status` to `account.json` manually can no longer bypass the Premium gate (#80)
- PIN hashing migrated from SHA-256 to Argon2id for brute-force resistance (CWE-916). Existing SHA-256 PINs are verified transparently and rehashed on next successful unlock; new PINs use Argon2id (#54)

### Security
- Closed CWE-312 (cleartext storage of OAuth tokens), CWE-345 (missing integrity check on the subscription cache), and CWE-916 (weak PIN hashing). Legacy `tokens.json` and legacy unsigned `account.json` caches are rejected by the gating path until the next token refresh re-establishes a keychain-anchored trust (#66, #54)

## [0.7.3] - 2026-04-13

### Fixed
- Maximus Account sign-in: the deep-link callback now uses the canonical Tauri v2 `on_open_url` API, so the auth code is properly received by the running app instead of leaving the UI stuck in "loading" (#51, #65)
- OAuth callbacks containing an `error` parameter now surface the error to the UI instead of being silently ignored (#51)

## [0.7.2] - 2026-04-13

### Changed
- Auto-updates are temporarily open to the Free edition until the license server (issue #49) is live. Gating will be restored once paid activation works end-to-end (#48)

## [0.7.1] - 2026-04-13

### Fixed
- Maximus Account sign-in: the OAuth2 callback now correctly returns to the running app instead of launching a second instance and leaving the original one stuck in "loading" (#51, #65)

## [0.7.0] - 2026-04-11

### Added
- CI: new `check.yml` workflow runs `cargo check`/`cargo test` and the frontend build on every branch push and PR, catching errors before merge instead of waiting for the release tag (#60)
- License card in Settings page: shows the current edition (Free/Base/Premium), accepts a license key, and links to the purchase page (#47)
- Maximus Account card in Settings: optional sign-in via OAuth2 PKCE for Premium features (#51)
- Machine activation: activate/deactivate machines against the license server, view activated machines in the license card (#53)
- Daily subscription status check: automatically refreshes account info once per day at launch (#51)

### Changed
- Automatic updates are now gated behind the Base edition entitlement; the Free edition shows an upgrade hint instead of fetching updates (#48)
- Edition detection now considers Maximus Account subscription: Premium overrides Base when subscription is active (#51)
