Wrap transaction_type in col() for notin_ filter

SQLModel enum columns need col() to expose SQLAlchemy operators like
notin_. Without it the agent tool raised at query build time and the
chat card flashed away.

 ## Deployment
 
 - Deployed via Gitea Actions (self-hosted runner on VPS)
 - Push to `main` triggers: GitHub → webhook → Gitea mirror sync → Actions workflow → Docker build & deploy
 - Domain: wealth.cescalante.dev
 - Reverse proxy: nginx-proxy + acme-companion (auto TLS)
+
+## Infrastructure
+
+- **Single server**: `ssh old-vps` — runs everything (WealthySmart, n8n, Forgejo, Vaultwarden, nginx-proxy)
+- `ssh production` is **NOT valid** — do not use
+- n8n UI: https://n8n.cescalante.dev — n8n DB queryable via `docker exec portfolio-db-prod psql -U portfolio_user -d n8n`
+
+## n8n Flows
+
+Four automated flows on old-vps feed data into WealthySmart:
+
+1. **BAC Credit Card** — Gmail trigger → POST /transactions/
+2. **Salary Deposits** — Gmail trigger → POST /transactions/
+3. **Municipal Receipts** — Cron trigger → POST /municipal-receipts/upload
+4. **Pension PDFs** (`e88c3UhBeo9WCbcy`) — Gmail trigger (daily midnight) → POST /pensions/upload

+SYSTEM_PROMPT = """You are the WealthySmart assistant, an AI analyst for a
+personal-finance app owned by a single user (Carlos).
+
+Context you can rely on:
+- The user's primary currency is Costa Rican colones (CRC, ₡). USD and EUR
+  balances and transactions are always converted to CRC using the latest
+  exchange rate before being summed.
+- Credit-card billing cycles run from the 18th of a month to the 18th of the
+  following month. When the user says "this month" or "last month" without
+  qualifiers, assume they mean the calendar month unless they mention
+  "cycle", "corte", or their credit card.
+- Today's date is {today}. Use it when the user says "this month", "last
+  month", "last year", etc.
+- Amounts are stored as raw numbers in their native currency (see `currency`
+  field on transactions/accounts). Tools that return `total_crc` are already
+  converted; tools that return per-transaction amounts are NOT.
+
+How to answer:
+- ALWAYS call a tool to get data. Do not invent balances, dates or merchants.
+- Call multiple tools in parallel when the question spans domains
+  (e.g. net worth + recent transactions).
+- Format currency with the appropriate symbol: ₡ for CRC (no decimals), $ for
+  USD (two decimals), € for EUR (two decimals).
+- When showing lists, prefer markdown tables over prose.
+- If a tool returns no data, say so explicitly — do not fill in zeros.
+- You are read-only in this version. If asked to create, edit or delete
+  anything, explain that write actions aren't available yet and offer to
+  summarize or export the change instead.
+
+Language: match the user. The app is bilingual (Spanish/English); respond in
+whichever language they used.
+
+Generative UI — render tools:
+- When showing spending totals, cycle summaries, or category breakdowns →
+  call render_spending_summary. Source data: get_cycle_summary (by_source,
+  grand_total_crc) + get_analytics_by_category (by_category).
+- When showing transaction lists or other structured data →
+  call render_a2ui in a SEPARATE tool-call step, only after all data-fetching
+  calls have returned. NEVER call render_a2ui in the same batch as any other
+  tool.
+- Do NOT use markdown tables for data a render tool can display.
+- CRITICAL RULE: When you call a render tool (render_spending_summary or
+  render_a2ui), that tool call MUST be the ONLY content in your message.
+  Do NOT include any text content alongside the tool call — no introduction,
+  no list, no explanation, nothing. The rendered card IS the complete
+  response. Any text you write in the same message as a render call will
+  appear as a duplicate below the card, which is wrong.

+# A2UI Theming Findings
+
+Captured 2026-04-28 while researching how to beautify the table the agent renders via `render_a2ui` without overriding component internals.
+
+## TL;DR
+
+- A2UI v0.9 docs prescribe theming through a small set of **documented top-level CSS variables** declared on `:where(:root)` (zero specificity, so host CSS wins without `!important`).
+- Default theme uses `light-dark()` so tokens self-toggle. Recommended dark-mode coupling: add the documented `a2ui-dark` class on `<html>` whenever Tailwind's `.dark` is on; that flips `color-scheme: dark` and resolves every `light-dark()` to its dark branch.
+- **In our app, this approach has near-zero visible effect.** We render through `@copilotkit/a2ui-renderer` (React variant), not `@a2ui/lit`. Inspecting the compiled React renderer (`node_modules/.pnpm/@copilotkit+a2ui-renderer@1.56.4/.../catalog/basic/components/*.mjs`), every component uses **hardcoded inline styles**; the only CSS variable consumed across the whole basic catalog is `--a2ui-primary-color`.
+- This matches open issues `google/A2UI#977` and `#1285` ("React renderer parity is incomplete").
+
+## Documented token surface (Lit / Angular)
+
+From `tech_docs/A2UI/renderers/web_core/src/v0_9/basic_catalog/styles/default.ts`:
+
+- Color palette: `--a2ui-color-background`, `--a2ui-color-on-background`, `--a2ui-color-surface`, `--a2ui-color-on-surface`, `--a2ui-color-primary`, `--a2ui-color-primary-light/-dark/-hover`, `--a2ui-color-on-primary`, `--a2ui-color-secondary`, `--a2ui-color-secondary-light/-dark/-hover`, `--a2ui-color-on-secondary`, `--a2ui-color-input`, `--a2ui-color-on-input`, `--a2ui-color-border`.
+- Borders: `--a2ui-border`, `--a2ui-border-width`, `--a2ui-border-radius`.
+- Typography: `--a2ui-font-family-title`, `--a2ui-font-family-monospace`, `--a2ui-font-size`, `--a2ui-font-scale`, `--a2ui-font-size-xs..2xl`, `--a2ui-line-height-headings`, `--a2ui-line-height-body`.
+- Spacing: `--a2ui-grid-base`, `--a2ui-spacing-xs..xl`.
+
+Per-component tokens like `--a2ui-card-background` exist but the renderer README and the official theming guide explicitly frame them as catalog-internal, not stable spec. Avoid relying on them.
+
+## Dark-mode coupling
+
+A2UI default uses `light-dark(...)` and supports forced modes via `a2ui-light` / `a2ui-dark` classes (see the `:where(.a2ui-dark)` block in `default.ts`). Best practice for a host that uses Tailwind `.dark` on `<html>`: toggle the matching `a2ui-dark` class in lockstep — one effect-driven `useEffect`, or add it directly to the root if the app is dark-only. No need to redeclare every token under `.dark`; the default rules already pick up the right branch through `light-dark()`.
+
+## Footguns in v0.9
+
+- The agent-supplied `theme` payload (e.g. `createSurface.theme.primaryColor`) is **not yet wired** in the basic catalog. Tracked in `google/A2UI#979` (Lit) and `#977` (React). Don't expect agent-side theming to recolor anything in v0.9; only the host CSS does.
+- `hintedStyles` (h1–h6 mappings) require all keys when overridden — see `google/A2UI#602`.
+- Tracking issues for the broader theming surface: `google/A2UI#1083`, `#1118`.
+
+## Why this won't move the table in our app
+
+`@copilotkit/a2ui-renderer@1.56.4` (React) is what `<CopilotKit a2ui={{}}>` plugs in. Its components apply colors and borders as inline `style` props (`backgroundColor: "#fff"`, `border: "1px solid #ccc"`, etc.). Inline styles can only be overridden with `!important` in author CSS, which contradicts the "don't take its freedom" goal. So the documented `--a2ui-*` token contract is currently a **Lit-only surface** for this catalog.
+
+## Practical options for this codebase
+
+1. **Quick win**: set `--a2ui-primary-color: var(--primary)` on `:root`. Real but small effect (primary buttons, links).
+2. **Prompt-side polish**: instruct the agent to compose richer A2UI structures — wrap the table in a `Card`, use `usageHint: "h3"` for the section title, insert a `Divider`, group columns with `Row` + `Column` weights — so the renderer's existing inline styles produce a cleaner result. No code change.
+3. **Switch renderer**: replace `@copilotkit/a2ui-renderer` with `@a2ui/lit` (or wait for `@a2ui/react` parity). Then every documented `--a2ui-*` token actually applies. Non-trivial migration.
+4. **Custom catalog overrides**: register replacement React components for `Row`/`List`/`Card` via `createA2UICatalog`; full control, most invasive, accepts ownership of those components forever.
