 # Copilot Instructions — Fiddy (External DB)
 
-## Source of truth
-- Always consult PROJECT_INSTRUCTIONS.md at the repo root.
-- If any guidance conflicts, PROJECT_INSTRUCTIONS.md takes precedence.
-- Keep this file focused on architecture/stack; keep checklists and project workflow rules in PROJECT_INSTRUCTIONS.md.
-- When asked to fix bugs, follow DEBUGGING_INSTRUCTIONS.md at the repo root.
+## Authority
+- **Source of truth:** `PROJECT_INSTRUCTIONS.md` (repo root). If conflict, follow it.
+- **Bugfix work:** follow `DEBUGGING_INSTRUCTIONS.md` (repo root).
+- Keep this file short: it’s a guide for Copilot behavior, not the full spec.
 
-## Stack
-- Monorepo (npm workspaces)
-- Next.js (App Router) + TypeScript + Tailwind
-- External Postgres (on-prem server) via node-postgres (pg). No ORM.
-- Docker Compose dev/prod
-- Gitea + act-runner CI/CD
+## High-level behavior
+- Make the **smallest change** that resolves the bug or request.
+- **Scan the repo first** for existing patterns (don’t invent files/endpoints unless necessary).
+- Respect layering: **route → server service → client wrapper → hook → UI**.
+- Keep diffs tight; avoid large refactors unless required.
 
-## Environment
-- Dev and Prod must use the same schema/migrations (`packages/db/migrations`).
-- `DATABASE_URL` points to the external DB server (NOT a container).
+## Hard rules (do not violate)
+- External DB: `DATABASE_URL` points to on-prem Postgres (NOT a container).
+- No cron/worker jobs.
+- Server-side RBAC only; client checks are UX only.
+- Never log secrets, receipt bytes, or full invite codes (invite codes = **last4 only**).
+- Entries list endpoints must never return receipt bytes.
 
-## Auth
-- Custom email/password auth.
-- Use HttpOnly session cookies backed by DB table `sessions`.
-- NEVER trust client-side RBAC checks.
+## Architecture quick map (follow existing patterns)
+- API routes: `app/api/**/route.ts` (thin parse/validate + call service)
+- Server services: `lib/server/*` (DB + authz, must include `import "server-only";`)
+- Client wrappers: `lib/client/*` (typed fetch + error normalization, credentials included)
+- Hooks: `hooks/use-*.ts` (UI-facing API layer; components avoid raw `fetch()`)
 
-## Receipts
-- Store receipt images in Postgres `bytea` table `receipts`.
-- Entries list endpoints must not return image bytes.
-- Image bytes only fetched by separate endpoint when inspecting a single item.
+## API conventions
+- Prefer error shape: `{ error: { code, message }, request_id? }`
+- Validate input at the route boundary; authorize in services.
 
-## UI
+## Next.js dynamic route params (required)
+- In `app/api/**/[param]/route.ts`, treat `context.params` as async:
+  - `const { id } = await context.params;`
+
+## Tests
+- When changing API behavior, add/update tests.
+- Prefer including negative cases: unauthorized / not-a-member / invalid input.
+
+## UI expectations
 - Dark mode, minimal, mobile-first.
-- Dodger Blue accent (#1E90FF).
-- Top navbar: left nav dropdown, middle group selector, right user menu.
-
-## Code Rules
-- Small files, minimal comments.
-- Prefer single-line `if` without braces when only one line follows.
-- Heavy logic lives in components/hooks/services, not page files.
-- Prefer API calls via exported hooks/services for reusability and cleanliness (avoid raw fetch in components when possible).
-- Add/update unit tests with changes (TDD).
-- Heavy focus on code readability and maintainability; prioritize clean code over clever code.
-  - ie. Separating different concerns into different files, and adding helper functions to avoid nested logic and improve readability, is preferred over clever one-liners or consolidating logic into fewer files.
-  - ie. Separate groups of related codes by adding 3 line breaks between them
-
-## Data Model
-- Users (system_role USER|SYS_ADMIN)
-- Groups + membership (group_role MEMBER|GROUP_ADMIN)
-- Entries (group-scoped) + optional receipt_id
-- User settings (jsonb)
-- Reports for system admins
-
-## Architecture Contract (Backend ↔ Client ↔ Hooks ↔ UI)
-
-### No-Assumptions Rule (Required)
-- Before making structural changes, first scan the repo and identify:
-  - the web app root (where `app/`, `components/`, `hooks/`, `lib/` live)
-  - existing API routes and helpers
-  - existing patterns already in use
-- Do not invent files, endpoints, or conventions. If something is missing, add it minimally and consistently.
-
-### Layering (Hard Boundaries)
-For every domain (auth, groups, entries, receipts, etc.), keep a consistent 4-layer flow:
-
-1) **API Route Handlers** (`app/api/.../route.ts`)
-- Thin: parse input, call a server service, return JSON.
-- No direct DB queries inside route files unless there is no existing server service.
-- Must enforce auth & membership checks on server.
-
-2) **Server Services (DB + authorization)** (`lib/server/*`)
-- Own all DB access and authorization helpers (sessions, requireGroupMember, etc.).
-- Server-only modules must include `import "server-only";`
-- Prefer small domain modules: `lib/server/auth.ts`, `lib/server/groups.ts`, `lib/server/entries.ts`, `lib/server/session.ts`.
-
-3) **Client API Wrappers** (`lib/client/*`)
-- Typed fetch helpers only (no React state).
-- Centralize `fetchJson()` / error normalization.
-- Always send credentials (cookies) and never trust client-side RBAC.
-
-4) **Hooks (UI-facing API layer)** (`hooks/use-*.ts`)
-- Hooks are the primary interface for components/pages to call APIs.
-- Components should not call `fetch()` directly unless there’s a strong reason.
-
-### Domain Blueprint (Consistency Rule)
-For any new feature/domain, prefer:
-- `app/api/<domain>/...`
-- `lib/server/<domain>.ts`
-- `lib/client/<domain>.ts`
-- `hooks/use-<domain>.ts`
-- `components/<domain>/*`
-- `__tests__/<domain>.test.ts`
-
-### API Conventions
-- Prefer consistent JSON response shape for errors:
-  - `{ error: { code: string, message: string } }`
-- Validate inputs at the route boundary (basic shape/type), and validate authorization in server services.
-- When adding endpoints, mirror existing REST style used in the project.
-
-### Non-Regression Contracts (Do Not Break)
-- Entries list endpoints must **never** include receipt image bytes; image bytes are fetched via a separate endpoint only.
-- Auth is DB-backed HttpOnly sessions; all auth checks are server-side.
-- Groups require server-side membership checks; active group persists per user.
-- Group invite codes:
-  - shown once immediately after group creation
-  - modal renders outside navbar/header so it overlays the viewport correctly
-  - avoid re-exposing invite code elsewhere without explicit “group settings” work
-
-### UI Structure
-- Page files stay thin; heavy logic stays in hooks/services/components.
-- Dark mode, minimal, mobile-first.
-- Dodger Blue accent (#1E90FF).
-- Navbar: left nav dropdown, middle group selector, right user menu.
-
-### Environment
-- Dev and Prod must use the same schema/migrations (`packages/db/migrations`).
-- `DATABASE_URL` points to external Postgres (NOT a container).
-- `DATABASE_URL` format must be a full connection string; URL-encode special chars in passwords.
-
-### Tests (Required)
-- Add/update tests for API behavior changes:
-  - auth
-  - groups
-  - entries (group scoping)
-- Tests must include negative cases: unauthorized, not-a-member, invalid inputs.
+- Navbar layout: left nav dropdown, middle group selector, right user menu.

+# Refactor 1 - Domain-First Folder Structure
+
+## Purpose
+Improve reviewability and long-term maintainability by moving from mostly flat frontend folders to a domain-first structure with clear ownership and lower coupling.
+
+## Scope
+- Frontend structure in `apps/web`
+- Instruction consistency updates
+- Incremental migration with compatibility shims
+- No behavior changes intended during structure migration
+
+## Source Of Truth And Alignment
+Use this precedence order when guidance conflicts:
+1. `PROJECT_INSTRUCTIONS.md` (repo-level source of truth)
+2. `.github/copilot-instructions.md` (architecture and coding rules)
+3. `docs/03_REFACTOR_1.md` (this execution tracker and decisions for Refactor 1)
+
+Current refactor-alignment decisions:
+- Canonical entry->bucket mutation mechanism: `EntryMutationContext`
+- Domain-first target layout: `apps/web/features/<domain>/...` and `apps/web/shared/...`
+- Compatibility re-exports removed on 2026-02-12; new imports must use feature-owned paths
+
+## Context Compression Guardrails
+- At the start of each new session, read this file and the two source-of-truth docs above.
+- Before implementation, re-state active decisions from "Current refactor-alignment decisions".
+- Add noteworthy changes to "Notes Log" immediately when discovered.
+- Do not introduce a second mechanism for any existing concern without logging a decision here first.
+
+## Phase 0 - Architecture Alignment (single mechanism rule)
+- [x] Decide one canonical entry->bucket mutation mechanism (`context` OR `event`)
+- [x] Remove the non-canonical mechanism and all references
+- [x] Verify there is no duplicate refresh trigger path
+- [x] Document chosen mechanism in instructions
+
+## Phase 1 - Instruction and Governance Updates
+- [x] Update `.github/copilot-instructions.md`
+- [x] Update `PROJECT_INSTRUCTIONS.md`
+- [x] Add "single mechanism per concern" rule
+- [x] Add file-size/complexity refactor thresholds
+- [x] Add dead-path cleanup rule
+- [x] Add architecture-consistency checklist to PR expectations
+
+## Phase 2 - Folder Structure Scaffolding
+- [x] Create `apps/web/features/`
+- [x] Create `apps/web/shared/`
+- [x] Define domain folders:
+  - [x] `features/entries`
+  - [x] `features/buckets`
+  - [x] `features/groups`
+  - [x] `features/tags`
+  - [x] `features/auth`
+- [x] Add minimal README/tree notes in new folders (optional but recommended)
+
+## Phase 3 - Incremental Domain Migration
+### Entries + Buckets first (highest coupling)
+- [x] Move entries UI/components into `features/entries/components`
+- [x] Move buckets UI/components into `features/buckets/components`
+- [x] Move domain hooks into `features/<domain>/hooks` (or keep centralized with strict naming, pick one and stay consistent)
+- [x] Add temporary compatibility re-exports from old paths
+
+### Remaining domains
+- [x] Migrate groups
+- [x] Migrate tags
+- [x] Migrate auth
+
+## Phase 4 - Import and Boundary Cleanup
+- [x] Replace legacy imports with new feature paths
+- [x] Ensure container vs presentational separation in large panels
+- [x] Remove obsolete compatibility re-exports once import migration is complete
+- [x] Remove dead files and stale helpers
+
+## Phase 5 - Validation and Non-Regression
+- [x] Run typecheck
+- [ ] Run lint
+- [x] Run relevant unit tests
+- [ ] Smoke-test key UI flows:
+  - [ ] Entry create/update/delete
+  - [ ] Bucket usage updates
+  - [ ] Edit modal discard behavior
+  - [ ] Group switch behavior
+
+## Phase 6 - Consolidation
+- [ ] Publish final structure map in docs
+- [ ] Confirm all checklist items closed
+- [ ] Capture lessons learned and follow-up actions
+

+- [YYYY-MM-DD] Alignment Snapshot:
+  - Active mechanism:
+  - Active folder strategy:
+  - Remaining migration risk:
+- [2026-02-12] Observation:
+  - Context: Entry->bucket mutation flow had architectural drift (context + custom event mechanism both present).
+  - Impact: Higher cognitive load and harder debugging/review for regressions.
+  - Decision: Standardized on `EntryMutationContext`; removed `entry-mutation-events`.
+  - Follow-up: Keep scanning for duplicate state propagation patterns during domain migration.
+- [2026-02-12] Observation:
+  - Context: During migration edits, a literal `` `r`n `` sequence was accidentally inserted in `entries-panel.tsx`.
+  - Impact: Broke readability and could have caused compile/runtime issues.
+  - Decision: Fixed immediately and added note to keep encoding/text clean during scripted edits.
+  - Follow-up: Keep post-edit grep checks for suspicious escaped literals.
+
+- [2026-02-12] Observation:
+  - Context: `npx tsc --noEmit` still fails on pre-existing server/test typing issues unrelated to this refactor slice.
+  - Impact: Full type-green gating cannot yet be used as a migration stop condition.
+  - Decision: Track failures as known baseline until addressed in separate debt fixes.
+  - Follow-up: Re-run typecheck after each migration phase and confirm no net-new errors.
+- [2026-02-12] Observation:
+  - Context: Alignment details were spread across multiple docs and easy to miss after context compression.
+  - Impact: Higher risk of inconsistent implementation choices between sessions.
+  - Decision: Added explicit source-of-truth precedence and context-compression guardrails in this file.
+  - Follow-up: Keep the "Current refactor-alignment decisions" block updated whenever a major choice changes.
+- [2026-02-12] Observation:
+  - Context: Hook migration started with entries and buckets domains.
+  - Impact: Domain ownership is clearer; old import paths still function via compatibility re-exports.
+  - Decision: Keep compatibility exports in `apps/web/hooks` until remaining domains are migrated.
+  - Follow-up: Migrate groups/tags/auth hooks and then remove legacy re-exports.
+- [2026-02-12] Observation:
+  - Context: Migrated auth/groups/tags hooks into `apps/web/features/*/hooks` and converted legacy `apps/web/hooks/use-*.ts` files to compatibility re-exports.
+  - Impact: Domain ownership is now explicit while existing imports remain functional during the transition.
+  - Decision: Keep compatibility shims until Phase 4 import cleanup is complete.
+  - Follow-up: Remove compatibility shims in Phase 4 after all legacy component path re-exports are retired.
+- [2026-02-12] Alignment Snapshot:
+  - Active mechanism: `EntryMutationContext`
+  - Active folder strategy: domain-first features (`apps/web/features/<domain>/{components,hooks}`)
+  - Remaining migration risk: leftover compatibility imports and large mixed-responsibility panels.
+- [2026-02-12] Observation:
+  - Context: Replaced the final app-level `@/hooks/use-*` import (`apps/web/components/recurring-entries-panel.tsx`) with a feature hook import.
+  - Impact: Runtime code now reads hooks from feature-owned locations; `apps/web/hooks/use-*.ts` are compatibility shims only.
+  - Decision: Keep shims temporarily for migration safety.
+  - Follow-up: Delete hook shims during Phase 4 once no external references remain.
+- [2026-02-12] Observation:
+  - Context: PowerShell write operations introduced BOM and mojibake artifacts in a few migrated files.
+  - Impact: Increased review noise and risk of accidental text regressions.
+  - Decision: Normalized touched files to UTF-8 without BOM and replaced unstable glyphs with ASCII-safe equivalents.
+  - Follow-up: Prefer no-BOM file writes and run a quick mojibake scan after scripted edits.
+- [2026-02-12] Observation:
+  - Context: Removed obsolete compatibility re-export files under `apps/web/components` and `apps/web/hooks/use-*.ts`.
+  - Impact: Reduced duplicate paths and eliminated stale import targets.
+  - Decision: Treat `apps/web/features/*` as the only valid home for migrated component/hook implementations.
+  - Follow-up: Continue Phase 4 by splitting large panels and removing any remaining dead paths.
+- [2026-02-12] Observation:
+  - Context: `apps/web/components/recurring-entries-panel.tsx` and `apps/web/hooks/use-recurring-entries.ts` had no references and were removed.
+  - Impact: Fewer dead maintenance paths and clearer active surface area.
+  - Decision: Keep recurring-entry behavior in server/client domain modules only until a routed UI is reintroduced.
+  - Follow-up: If recurring UI returns, add it directly under `features/entries/components`.
+- [2026-02-12] Observation:
+  - Context: Lint validation is currently blocked because `npm run lint` calls `next lint` (invalid for current Next setup) and direct `eslint` has no config file.
+  - Impact: Lint cannot be used yet as a gating signal in this repo state.
+  - Decision: Keep lint checklist unchecked and treat as tooling debt.
+  - Follow-up: Add/restore ESLint config and update lint script before enforcing lint gates.
+- [2026-02-12] Observation:
+  - Context: Split `features/entries/components/entries-panel.tsx` by extracting `EntriesList`, `EntriesFilterModal`, and `EntriesDiscardModal`.
+  - Impact: Smaller container panel with clearer behavior vs presentation boundaries and simpler review scope.
+  - Decision: Keep stateful orchestration in `EntriesPanel` and move UI-heavy rendering to dedicated presentational components.
+  - Follow-up: Apply the same split pattern to other oversized panels (notably group settings) in a later pass.
+## Known Notes (seed)
+- [x] Entry->bucket update mechanism currently shows architectural drift (context and event patterns both present in codebase references).
+- [x] `entries-panel.tsx` remains large and should be split during migration for reviewability.
+- [ ] Preserve behavior while moving files; avoid functional changes in structure-only PRs.
+
+## Exit Criteria
+- Single, documented mutation propagation mechanism in use.
+- Domain-first structure in place and imports migrated.
+- No stale paths or duplicate mechanisms left.
+- Validation checks pass (or known pre-existing failures documented separately).

 ### Risks / Notes to Revisit
 - Workspace is intentionally dirty; commits must be path-scoped to avoid mixing unrelated changes.
-- `npm run lint` currently fails due `next lint` invocation behavior in this environment; lint verification needs explicit follow-up task.
+- This Codex session currently cannot write to `.git` (index lock permission denied), so local user-side commits are required for newly staged changes.
