## Workflow
0. **Pré-vol — revalider le tip localement.** `check.yml` ne tourne pas sur `main` : le tip mergé n'a jamais été vu par le CI (le dernier run vert portait sur la branche d'issue avant merge), et le tag grave ce tip exact dans des binaires distribués. Lancer `npm run build && npm test` (vitest) + `cd src-tauri && cargo check && cargo test`. Vérifier aussi que `.claude/worktrees/` est vide (worktrees leftover → vitest récurse et gonfle le compteur). Ne tagger que sur un tip vert.
1. Determiner la nouvelle version (argument utilisateur ou demander)
2. Bump version dans les 5 fichiers :
- `src-tauri/Cargo.toml` (ligne `version = "..."`)

```
7. Push : `git push origin main && git push origin vX.Y.Z`
8. Forgejo CI build automatique (Windows + Linux) via `release.yml` sur `on: push: tags: v*`
9. **Post-CI — vérifier la release publiée.** Surveiller `release.yml` (outil `Monitor` sur le run), puis vérifier la release réellement attachée — `status=success` du workflow ne suffit pas :
- Les **7 artefacts** attendus : `.exe` NSIS, `.deb`, `.rpm`, leurs 3 signatures `.sig`, et `latest.json`.
- Le contenu de `latest.json` (il pilote l'auto-update des installations existantes) : champ `version` correct, signatures non vides pour les deux plateformes, URLs pointant vers les bons binaires, notes extraites du CHANGELOG.
## Regles
@ -45,7 +49,9 @@ updated: 2026-07-01
- Format Keep a Changelog : `## [X.Y.Z] - YYYY-MM-DD`
- Les changelogs sont bundles dans `public/` pour l'affichage in-app
- Tag **annote** (`-a`), pas lightweight : les artefacts CI reference le tag pour les release notes
- **Tagger publie vers l'extérieur** : `release.yml` pousse le JSON d'updater, donc les utilisateurs installés reçoivent la mise à jour automatiquement. Confirmer avec Max avant de tagger.
## Changelog
- 2026-04-19 — Added Cargo.lock + package-lock.json to bump list, `npm install --package-lock-only` fallback when lockfile stale, explicit `[Unreleased]` migration pattern, annotated tags (#102/#112 release cycle)
- 2026-07-01 — Documenter que le header FR est `## [Non publié]` (≠ `[Unreleased]`), pour éviter le faux diagnostic « changelog FR vide » lors de la migration. Source : session 5466da98.
- 2026-07-13 — Étape 0 (pré-vol) : revalider le tip localement avant de tagger — `check.yml` ne tourne pas sur `main`, le tip mergé n'a jamais été vu par le CI ; vérifier `.claude/worktrees/` vide (vitest récurse sinon). Étape 9 (post-CI) : vérifier la release publiée — 7 artefacts attendus + contenu de `latest.json` (pilote l'auto-update) ; `status=success` ne suffit pas. Règle : tagger publie vers l'extérieur (updater automatique) → confirmer avec Max avant de tagger. Source : session fdda84cb (release v0.13.0).

## [Non publié]
### Modifié
- Rapports : les trois tableaux de rapport hiérarchiques (Comparaison réel-vs-réel, réel-vs-budget, et Tendances par catégorie) permettent désormais de **replier ou déplier chaque niveau de la hiérarchie de catégories**, plus seulement le premier. Chaque catégorie parente — y compris les intermédiaires — porte son propre chevron ; en déplier une révèle ses enfants directs (eux-mêmes repliés), pour descendre un niveau à la fois. Les tableaux s'ouvrent entièrement repliés (seules les catégories de premier niveau visibles), « Tout déplier » ouvre tous les niveaux d'un coup, et vos choix de repli sont désormais enregistrés **par profil** — dans la base de données du profil, donc détruits avec lui — au lieu du navigateur. Les sous-totaux et les lignes de résultat restent rigoureusement inchangés quel que soit ce que vous repliez (#288).

## [Unreleased]
### Changed
- Reports: the three hierarchical report tables (real-vs-real Compare, real-vs-budget Compare, and Trends by category) now let you **collapse or expand every level of the category hierarchy**, not just the top level. Every parent category — including the intermediate ones — carries its own chevron; expanding one reveals its direct children (themselves collapsed), so you drill down one level at a time. The tables open fully collapsed (only the top-level categories visible), "Expand all" opens every level at once, and your collapse choices are now saved **per profile** — in the profile's own database, so they are destroyed with the profile — instead of in the browser. Subtotals and result lines stay exactly the same whatever you fold away (#288).

* Per-report collapse/expand state for the hierarchical comparable tables

* value is the set of *expanded* group keys, so a first-ever visit (empty set)
* shows every group collapsed with only its subtotal, while any group the user
* expands is remembered.
* Per-report collapse/expand state for the hierarchical tables (issue #254/#265),
* generalised to every hierarchy level (issue #288).
*
* Persistence uses localStorage, the same synchronous store the sibling
* "subtotals on top/bottom" toggle already uses in these tables. State is kept
* per report via a distinct `storageKey`.
* The persisted value is the set of keys whose state DIFFERS from the default
* (see `isCollapsedFor`), so `defaultExpanded: false` + an empty set = everything
* collapsed the reports' established behaviour while `defaultExpanded: true`
* + an empty set = everything expanded.
*
* Persistence lives in `user_preferences`, the profile's own SQLite table, so the
* state is scoped per profile for free and is destroyed with the profile (no
* localStorage residue surviving `deleteProfile` a privacy-first requirement).
* Reads/writes are async; hydration runs in an effect. There is no visible flash
* because the default state IS what renders first, and hydration can only reveal
* what the user had opened. `storageKey: null` disables persistence entirely
* (pure in-memory state, for the category trees).
*
* The hook stays context-free it never calls `useProfile()` because the
* `user_preferences` key is already per-profile (it lives in the profile's DB).

/**
* Collapse/expand of top-level category groups in the hierarchical comparable
* reports (real-vs-real Compare + Budget-vs-Actual) issue #254.
* Collapse/expand of category groups in the hierarchical reports (real-vs-real
* Compare, Budget-vs-Actual, trends over time) issue #254/#265, generalised to
* every hierarchy level in issue #288.
*
* Pure helpers only; the React state + persistence glue lives in the
* `useCollapsibleGroups` hook.
*
* A "group" is a top-level parent row (depth 0, is_parent). Collapsing it keeps
* its own subtotal row visible but hides its entire subtree (every following
* depth 1 row until the next depth-0 row). Rows must arrive in depth-first
* order the order the compare/budget services already emit them in, and the
* same order `reorderRows` relies on.
* Visibility is decided by an ANCESTOR WALK, not by row adjacency: a row is
* hidden iff *any* of its ancestors is collapsed. We climb `parentKeyOf` from a
* row until we reach a root (null), an ancestor outside this section ( visible),
* or a collapsed ancestor ( hidden). This is independent of the order rows
* arrive in the fix for the v1 adjacency algorithm, which assumed a
* depth-first order the budget grid (level-ordered) does not emit.
*
* The accessors are passed in rather than read off fixed field names so each
* table can supply the *exact* depth expression it renders with (CategoryDelta
* uses `depth ?? 0`; BudgetVsActualRow derives a missing depth from
* `parent_id`). Keeping the collapse depth and the indentation depth identical
* guarantees the hidden rows are exactly the indented descendants.
* The accessors are supplied by each consumer so every table can key + climb the
* exact hierarchy it renders. Keys are prefixed `p:` so they are injective: a
* parent subtotal row and its own "(direct)" leaf share a category id but the
* leaf is never a parent, so only the subtotal is indexed the leaf simply
* carries the parent's key via `parentKeyOf` and is hidden with it.
