## Spaces / Business plan — Phase 0: invisible foundation
First of **three stacked PRs** introducing multi-tenant **Spaces** (the
basis for the Business plan). This one is a **pure, behaviour-preserving
foundation**: it can ship to production on its own with zero
user-visible change.
- **Stacked PRs:** this → `enterprise-spaces-ui` (Phase 1+2) →
`enterprise-spaces-invitations` (Phase 3).
### What a Space is
A Space groups its own accounts, connections, transactions, categories,
labels, budgets and rules. **Every user gets one invisible "Personal"
space**, provisioned automatically on creation — so the architecture is
identical for free, Standard and Business accounts, even though only
Business will ever see more than one.
### What this PR does (no behaviour change)
- `spaces`, `space_user`, `space_invitations` tables;
`users.current_space_id`; a nullable, indexed `space_id` on the 8 owned
tables (plain column, **no FK** — avoids a validating table-scan/lock on
`transactions` during a phased rollout).
- `Space` model + `BelongsToSpace` trait that stamps `space_id` on
create (from the row's user's current space; a transaction inherits its
account's space, so bank-sync lands rows correctly).
- Idempotent, chunked `spaces:backfill` command (run from a migration)
that gives every existing user a personal space and stamps their rows —
so the read switch in the next PR is safe.
- **Reads are untouched here** (still user-scoped); every user has
exactly one space, so behaviour is identical.
### Testing
- New `tests/Feature/Spaces/SpaceFoundationTest.php` (provisioning,
default-space stamping, account-anchored transaction space,
stale-pointer self-heal, backfill).
- Full suite green.
### Notes / deliberate simplifications
- `space_id` stays **nullable** (populated by backfill + on every
write); the NOT NULL constraint is deferred until prod is confirmed
fully backfilled.
- For very large `transactions` tables, `spaces:backfill` can be run
out-of-band before deploy so the migration's call is a no-op.
## What
Reworks the filtered **transaction analysis drawer** to behave like a
*project view* — a coherent set of related transactions (a trip, a
rental, a renovation, a side hustle) — and surfaces data that was
already computable but never shown.
### Two shapes, auto-detected
The drawer adapts to whether the set is **expense-only** or **income +
expense**, detected from the income share (`income >= 15% of expense`).
A stray refund won't flip a trip into a P&L view; a rental's rent will.
- **Expense mode:** total spent, daily average, cumulative spend line.
- **Income mode:** net result + margin %, income vs expense bars,
cumulative **net** line.
The mode can be overridden per filter (Auto / Expenses only / Income &
expenses), mirroring the existing daily-average override exactly:
remembered in the browser per filter fingerprint and synced to a
matching saved filter via a new `analysis_mode` column + PATCH endpoint.
### New panels (all from existing data)
- **Largest expenses** — top 5, expandable to 10, biggest spends first.
- **Spending by payee** — horizontal bars, gated to ≥2 named payees.
- **Spending by account** — list, gated to ≥2 accounts.
### Smarter table
The largest-expenses table hides any column the filter or the rows have
pinned to a single value (e.g. filtering by one label drops the Labels
column; a one-category result drops the Category column).
## Tests
- **Backend:** new Pest coverage for `largest_expenses`, payee/account
breakdowns, `cumulative_net`, and the `analysis_mode` endpoint
(`TransactionAnalysisTest`, `SavedFilterTest`) — all green.
- **Frontend:** 9 vitest cases covering mode detection/override, the day
override, and column hiding.
- New `__()` keys added to `lang/es.json`.
## Notes
- Adds migration `add_analysis_mode_to_saved_filters_table`.
## Summary
Adds an **Analysis** button to the transactions toolbar (left of
Categorize) that opens a bottom-sheet dashboard summarizing the
transactions matching the current filters. Built around the Miami-trip
use case: tag a trip, filter to it, and see where the money went.
Everything is behind the existing `TransactionAnalysis` feature flag
(button hidden + endpoint returns 403 when off).
## Behavior
- **Button**: hidden unless `features.transactionAnalysis`. Disabled
until at least one filter is applied — desktop shows a hover tooltip,
mobile a tap dialog, both reading *"Apply a filter to enable this
button."*
- **Drawer** (vaul bottom-sheet, like the importer): fetches
`/api/transactions/analysis` with the current filters on open. Skeleton
+ empty/error states.
- **Charts**: KPI cards · spending over time (income/expense bars +
cumulative line, auto daily/monthly bucketing) · category donut + ranked
list (only when >1 category) · per-tag bars (only when >1 label).
- **Manual day override**: the *Avg / day* card has an editor to
override the date span used for the daily average (tickets bought months
ahead skew the span). Resolution precedence: matching saved filter's
`analysis_days` → `localStorage[fingerprint]` → auto span. Edits persist
to localStorage always, and sync to the saved filter when the current
filters match one.
## Backend
- `Api/TransactionAnalysisController@summary` — reuses
`Transaction::applyFilters()` + `IndexTransactionRequest`, converts to
the user's base currency via `ExchangeRateService` (rates preloaded),
rolls categories up through `CategoryTree`.
- `GET /api/transactions/analysis`.
- `analysis_days` (nullable) on `saved_filters` + `PATCH
/api/saved-filters/{id}/analysis-days`.
## Tests
- Pest: analysis endpoint (flag gating, totals, category/tag breakdown,
day/month bucketing, cumulative) + saved-filter day override
(set/clear/forbidden/invalid).
- Vitest: button gating (hidden/disabled/opens) + day-override
resolution (auto / saved-precedence / localStorage fallback / persists
to saved filter).
- New `lang/es.json` keys for all added strings.
## Notes
- Data is always sourced from the backend.
- The flag is still off by default — enable `TransactionAnalysis`
per-user to try it.
## What
Adds **saved filters** on the transactions page so users can name a set
of filters and reuse them later. The whole feature is gated behind a new
\`transaction-analysis\` Pennant feature flag (off by default).
## Why
Reusing the same filter combinations (e.g. "Japan trip", "Utilities") is
currently manual every time. This ports the saved-filters work from the
\`analysis-page\` branch, scoped down to **only** the transactions page
— the analysis screen and unrelated query changes from that branch are
intentionally left out.
## Changes
**Feature flag**
- \`App\Features\TransactionAnalysis\` — class-based flag, resolves
\`false\` by default.
- Shared to the frontend as \`features.transactionAnalysis\` and added
to the \`Features\` type.
**Backend (saved filters)**
- \`SavedFilter\` model (UUID, \`filters\` json cast, user belongsTo) +
migration + factory.
- \`Api\SavedFilterController\` — user-scoped index/store/update/destroy
under \`/api/saved-filters\`, ownership enforced with \`abort_unless\`.
- \`StoreSavedFilterRequest\` / \`UpdateSavedFilterRequest\` — name
unique per user, snake_case filter rules.
**Frontend**
- \`transaction-filter-serialization.ts\` —
serialize/deserialize/fingerprint between UI filter state and the
persisted snake_case shape.
- \`SavedFilters\` dropdown — load/save/update/delete with active +
dirty indicators.
- Integrated into the filter bar via an opt-in \`enableSavedFilters\`
prop, so it renders **only** on the transactions page (budgets/accounts
reuse the same component and stay unchanged). Render is also gated by
the feature flag.
**Filter bar UX**
- Split search + filters + saved searches onto their own row, separate
from the actions row (Categorize / Add transactions / columns), which
were getting cramped.
- On mobile, the text search moves into the filters popover.
## Reviewer notes
- Backend endpoints are **not** flag-gated; only the UI is, per the
request.
- Two-layer scoping: page opt-in prop **and** feature flag — flag off
means no UI anywhere.
- Translation keys fall back to the key (English); \`es.json\` entries
not added, matching the source branch.
## Testing
- \`tests/Feature/SavedFilterTest.php\` — 9 passing (auth, per-user
listing/uniqueness, ownership on update/delete).
- Pint, Prettier, ESLint clean. No new TypeScript errors introduced.
