feat: Cloudflare DNS management with automatic record sync

Add flexible DNS management to Docker Watcher. By default, wildcard DNS
is assumed (current behavior). When disabled, users can configure a
Cloudflare DNS provider with API token and zone selection. DNS A records
are automatically created/updated/deleted in sync with proxy consumers
(deployed instances and standalone proxies).

- Settings: wildcard_dns toggle, dns_provider, cloudflare credentials
- Cloudflare client: Provider interface with EnsureRecord/DeleteRecord/ListRecords
- DNS lifecycle hooks in deployer and proxy manager (best-effort)
- Settings UI: DNS config section with provider picker, zone selector, test button
- DNS Records page at /dns with filtering, sync status, reconciliation
- Records visible in both wildcard and managed modes
- Cleanup on provider change: removes old records when switching modes

+# Feature Context: Cloudflare DNS Management
+
+## Configuration
+- **Development mode:** Automated
+- **Execution mode:** Direct
+- **Strategy:** Big Bang
+- **Build (Go):** `go build ./cmd/server`
+- **Build (Frontend):** `cd web && npm run build`
+- **Check (Frontend):** `cd web && npm run check`
+- **Test:** `go test ./...`
+- **Dev server:** `./scripts/dev-server.sh` (port 8090)
+
+## Current State
+Starting fresh — no implementation yet.
+
+## Cross-Phase Dependencies
+- Phase 2 depends on Phase 1 (settings fields for Cloudflare credentials)
+- Phase 3 depends on Phase 2 (dns.Provider interface)
+- Phase 4 depends on Phase 1 (API endpoints for settings)
+- Phase 5 depends on Phase 2 + Phase 6 (client + sync logic)
+- Phase 6 depends on Phase 2 (Cloudflare client) + Phase 3 (dns_records table)
+
+## Key Architecture Decisions
+- DNS provider abstraction via `internal/dns.Provider` interface
+- Cloudflare API v4 via direct HTTP (no SDK) — keeps dependencies minimal
+- Local `dns_records` table tracks managed records for reconciliation
+- DNS operations are best-effort (log warnings, don't block deploys)
+- A records only, pointing to `ServerIP` from settings
+
+## Environment & Runtime Notes
+- Encryption key from `ENCRYPTION_KEY` env var (AES-256-GCM)
+- SQLite with WAL mode, auto-migration on startup
+- Frontend is SvelteKit 2 + Svelte 5 + Tailwind CSS 4

+# Feature: Cloudflare DNS Management
+
+**Branch:** `feature/cloudflare-dns-management`
+**Base branch:** `main`
+**Created:** 2026-04-02
+**Status:** 🟡 In Progress
+**Strategy:** Big Bang
+**Mode:** Automated
+**Execution:** Direct
+
+## Summary
+
+Introduce flexible DNS management. By default, wildcard DNS is assumed (current behavior).
+When disabled, the user selects a DNS provider (Cloudflare initially) and provides API
+credentials. DNS A records are then automatically kept in sync with proxy consumers
+(deployed instances and standalone proxies). A dedicated DNS Records page provides
+visibility, filtering, and manual sync/reconciliation.
+
+## Build & Test Commands
+- **Build (Go):** `go build ./cmd/server`
+- **Build (Frontend):** `cd web && npm run build`
+- **Check (Frontend):** `cd web && npm run check`
+- **Test (Go):** `go test ./...`
+- **Dev server:** `./scripts/dev-server.sh`

+# Phase 1: Settings Model & API
+
+**Status:** ⬜ Not Started
+**Parent plan:** [PLAN.md](./PLAN.md)
+**Domain:** backend
+
+## Objective
+Extend the Settings model and API to support DNS provider configuration.
+
+## Tasks
+
+- [ ] Task 1: Add new fields to `Settings` struct in `internal/store/models.go`
+  - `WildcardDNS` (bool, default true)
+  - `DNSProvider` (string, default "")
+  - `CloudflareAPIToken` (string, encrypted)
+  - `CloudflareZoneID` (string)
+- [ ] Task 2: Add migration columns in `internal/store/store.go`
+  - `wildcard_dns` INTEGER DEFAULT 1
+  - `dns_provider` TEXT DEFAULT ''
+  - `cloudflare_api_token` TEXT DEFAULT ''
+  - `cloudflare_zone_id` TEXT DEFAULT ''
+- [ ] Task 3: Update `GetSettings()` and `UpdateSettings()` in `internal/store/settings.go`
+  - Read/write new fields
+  - Encrypt/decrypt `cloudflare_api_token`
+- [ ] Task 4: Update `GET /api/settings` handler to include new fields (mask token)
+- [ ] Task 5: Update `PUT /api/settings` handler to accept new fields
+- [ ] Task 6: Add `POST /api/settings/dns/test` endpoint — validate Cloudflare token + zone
+- [ ] Task 7: Add `GET /api/settings/dns/zones` endpoint — list Cloudflare zones for picker
+- [ ] Task 8: Register new routes in `internal/api/router.go`
+
+## Files to Modify/Create
+- `internal/store/models.go` — add fields to Settings struct
+- `internal/store/store.go` — add migration columns
+- `internal/store/settings.go` — update read/write queries
+- `internal/api/settings.go` — update handlers, add new endpoints
+- `internal/api/router.go` — register new routes
+
+## Acceptance Criteria
+- New settings fields are persisted and retrievable
+- Cloudflare API token is encrypted at rest
+- GET /api/settings returns new fields (token masked)
+- PUT /api/settings accepts and stores new fields
+- DNS test and zones endpoints registered (can return placeholder until Phase 2)
+
+## Notes
+- Token encryption uses existing `crypto.Encrypt/Decrypt`
+- `has_cloudflare_api_token` bool in GET response (same pattern as npm_password)
+- DNS test/zones endpoints will make real Cloudflare API calls — Phase 2 client needed
+  for full implementation, but can use inline HTTP calls for these two endpoints
+
+## Review Checklist
+- [ ] All tasks completed
+- [ ] Code follows project conventions
+- [ ] No unintended side effects
+- [ ] Build passes
+- [ ] Tests pass (new + existing)
+
+## Handoff to Next Phase

+# Phase 2: Cloudflare DNS Client
+
+**Status:** ⬜ Not Started
+**Parent plan:** [PLAN.md](./PLAN.md)
+**Domain:** backend
+
+## Objective
+Create an `internal/dns` package with a `Provider` interface and a Cloudflare implementation
+using the Cloudflare API v4 (direct HTTP, no SDK).
+
+## Tasks
+
+- [ ] Task 1: Define `Provider` interface in `internal/dns/provider.go`
+  - `EnsureRecord(ctx, fqdn, ip) error` — create or update A record
+  - `DeleteRecord(ctx, fqdn) error` — delete A record if exists
+  - `ListRecords(ctx) ([]Record, error)` — list all A records in the zone
+  - `Record` struct: ID, FQDN, Type, Content (IP), Proxied, TTL
+- [ ] Task 2: Create `internal/dns/cloudflare.go` — Cloudflare implementation
+  - HTTP client with `Authorization: Bearer <token>` header
+  - Base URL: `https://api.cloudflare.com/client/v4`
+  - `EnsureRecord`: GET records by name, create if missing, update if IP differs
+  - `DeleteRecord`: GET record by name, DELETE if found
+  - `ListRecords`: GET all A records in zone
+  - `ListZones`: GET zones for the token (for zone picker)
+  - `TestConnection`: verify token works (GET /user/tokens/verify)
+- [ ] Task 3: Create `internal/dns/dns.go` — factory function
+  - `NewProvider(providerName, config) (Provider, error)`
+  - Config struct with token, zoneID
+  - Returns `nil, nil` when providerName is empty (wildcard mode)
+- [ ] Task 4: Wire DNS test/zones endpoints in `internal/api/settings.go`
+  - `POST /api/settings/dns/test` — create temp Cloudflare client, call TestConnection
+  - `GET /api/settings/dns/zones` — create temp client, call ListZones
+
+## Files to Modify/Create
+- `internal/dns/provider.go` — interface + Record type
+- `internal/dns/cloudflare.go` — Cloudflare implementation
+- `internal/dns/dns.go` — factory function
+- `internal/api/settings.go` — wire test/zones endpoints to real client
+
+## Acceptance Criteria
+- Provider interface defined with EnsureRecord, DeleteRecord, ListRecords
+- Cloudflare client makes correct API calls with proper auth headers
+- EnsureRecord is idempotent (create if missing, update if changed, no-op if same)
+- DeleteRecord is idempotent (no error if record doesn't exist)
+- ListZones returns zone ID + name pairs
+- TestConnection returns success/failure
+
+## Notes
+- Cloudflare API v4 docs: zones endpoint, dns_records endpoint
+- Use `context.Context` for timeout control on all HTTP calls
+- A records only (type "A"), TTL=1 (auto), proxied=false (DNS only, not CF proxy)
+
+## Review Checklist
+- [ ] All tasks completed
+- [ ] Code follows project conventions
+- [ ] No unintended side effects
+- [ ] Build passes
+- [ ] Tests pass (new + existing)

+# Phase 3: DNS Lifecycle Hooks
+
+**Status:** ⬜ Not Started
+**Parent plan:** [PLAN.md](./PLAN.md)
+**Domain:** backend
+
+## Objective
+Hook DNS record management into the deployer and standalone proxy manager so that DNS
+records are automatically created/updated/deleted in sync with proxy consumers.
+
+## Tasks
+
+- [ ] Task 1: Create `dns_records` table for tracking managed records
+  - Columns: id, fqdn, provider_record_id, consumer_type (instance/standalone), consumer_id, created_at, updated_at
+  - Store queries: CreateDNSRecord, DeleteDNSRecord, GetDNSRecordByFQDN, ListDNSRecords, GetDNSRecordsByConsumer
+- [ ] Task 2: Add DNS provider to `Deployer` struct
+  - Accept `dns.Provider` in constructor (can be nil for wildcard mode)
+  - Helper: `ensureDNS(ctx, fqdn, deployID)` — calls provider.EnsureRecord + saves to dns_records
+  - Helper: `removeDNS(ctx, fqdn, deployID)` — calls provider.DeleteRecord + removes from dns_records
+- [ ] Task 3: Hook into deployer — instance creation
+  - After `configureProxy` succeeds in `deployer.go` and `bluegreen.go` → call `ensureDNS`
+  - FQDN = `subdomain + "." + settings.Domain`
+- [ ] Task 4: Hook into deployer — instance removal
+  - In `removeInstance` after NPM proxy deletion → call `removeDNS`
+  - In `rollback` after NPM proxy deletion → call `removeDNS`
+- [ ] Task 5: Hook into standalone proxy manager
+  - `CreateProxy` → after NPM host created, call `ensureDNS`
+  - `UpdateProxy` → if domain changed, `removeDNS(old)` + `ensureDNS(new)`
+  - `DeleteProxy` → call `removeDNS`
+- [ ] Task 6: Wire DNS provider into main.go
+  - Read settings on startup, create provider if non-wildcard
+  - Pass provider to Deployer and proxy Manager constructors
+  - Handle provider being nil (wildcard mode = no DNS ops)
+- [ ] Task 7: Add `DNSRecord` model to `internal/store/models.go`
+
+## Files to Modify/Create
+- `internal/store/models.go` — add DNSRecord struct
+- `internal/store/store.go` — add dns_records table migration
+- `internal/store/dns_records.go` — CRUD queries
+- `internal/deployer/deployer.go` — add DNS hooks
+- `internal/deployer/bluegreen.go` — add DNS hooks
+- `internal/deployer/rollback.go` — add DNS cleanup
+- `internal/proxy/manager.go` — add DNS hooks
+- `cmd/server/main.go` — wire DNS provider
+
+## Acceptance Criteria
+- DNS records created when proxy consumers are created (if non-wildcard mode)
+- DNS records deleted when proxy consumers are removed
+- DNS records updated when standalone proxy domain changes
+- All DNS operations are best-effort (log warning on failure, don't block)
+- dns_records table tracks all managed records
+- Wildcard mode (default) skips all DNS operations
+
+## Notes
+- DNS operations must be wrapped in error handling that logs but doesn't fail the deploy
+- The dns_records table is the local source of truth for reconciliation (Phase 6)
+- Provider can be nil — all hooks must check for nil before calling

+# Phase 4: Settings UI — DNS Configuration
+
+**Status:** ⬜ Not Started
+**Parent plan:** [PLAN.md](./PLAN.md)
+**Domain:** frontend
+
+## Objective
+Add a "DNS Configuration" section to the Settings page with wildcard toggle, provider
+selection, Cloudflare credential fields, and connection test.
+
+## Tasks
+
+- [ ] Task 1: Add new API functions in `web/src/lib/api.ts`
+  - `testDnsConnection(token, zoneId)` → POST /api/settings/dns/test
+  - `listDnsZones(token)` → GET /api/settings/dns/zones
+- [ ] Task 2: Add i18n keys for DNS settings in locale files
+- [ ] Task 3: Add DNS Configuration section to `web/src/routes/settings/+page.svelte`
+  - Toggle: "Wildcard DNS is configured" (checkbox/switch)
+  - When unchecked, show:
+    - DNS Provider dropdown (only "Cloudflare" option)
+    - API Token field (password type, show `has_cloudflare_api_token` indicator)
+    - Zone picker (loaded from API after token provided)
+    - "Test Connection" button with success/error feedback
+  - All DNS fields hidden when wildcard is checked
+- [ ] Task 4: Wire save logic — include new fields in `handleSave`
+- [ ] Task 5: Wire load logic — populate DNS fields from settings response
+
+## Files to Modify/Create
+- `web/src/lib/api.ts` — add DNS API functions
+- `web/src/routes/settings/+page.svelte` — add DNS config section
+- `web/src/lib/i18n/en.ts` (or equivalent locale file) — add DNS translation keys
+
+## Acceptance Criteria
+- Wildcard toggle visible and functional (default: checked)
+- Unchecking reveals Cloudflare configuration form
+- API token field uses password masking
+- Zone picker loads zones from Cloudflare API
+- Test Connection button shows success/failure
+- Settings save includes DNS fields
+- Settings load populates DNS fields
+
+## Notes
+- Follow existing settings page patterns (FormField, EntityPicker for zones)
+- Zone picker similar to SSL certificate picker pattern
+- Token field similar to NPM password field (has_token indicator)
+
+## Review Checklist

+# Phase 5: DNS Records Page
+
+**Status:** ⬜ Not Started
+**Parent plan:** [PLAN.md](./PLAN.md)
+**Domain:** fullstack
+
+## Objective
+Create a dedicated DNS Records page that lists all managed DNS records with filtering,
+consumer mapping, and sync status visibility.
+
+## Tasks
+
+- [ ] Task 1: Add backend endpoint `GET /api/dns/records`
+  - Returns merged view: local dns_records + Cloudflare actual records
+  - Each record: fqdn, type, value (IP), consumer_type, consumer_name, status (synced/orphaned/missing)
+  - Orphaned = exists in Cloudflare but no local consumer
+  - Missing = local consumer exists but no Cloudflare record
+- [ ] Task 2: Add API handler in `internal/api/dns.go`
+  - New handler file for DNS-related endpoints
+  - Register routes in router.go
+- [ ] Task 3: Add frontend API function `getDnsRecords()` in `api.ts`
+- [ ] Task 4: Create DNS Records page at `web/src/routes/dns/+page.svelte`
+  - Table with columns: FQDN, Type, Value, Consumer, Status
+  - Consumer column shows: instance name (project/stage) or standalone proxy name
+  - Status badges: synced (green), orphaned (yellow), missing (red)
+  - Search filter (by FQDN substring)
+  - Filter by consumer type: all / managed / standalone
+  - Filter by status: all / synced / orphaned / missing
+  - Manual sync button (calls POST /api/dns/sync — Phase 6)
+  - Refresh button to re-fetch from Cloudflare
+- [ ] Task 5: Add navigation link to DNS page
+  - Only visible when wildcard DNS is disabled
+  - Add to sidebar/nav under Settings or as top-level
+- [ ] Task 6: Add i18n keys for DNS records page
+
+## Files to Modify/Create
+- `internal/api/dns.go` — new handler file
+- `internal/api/router.go` — register DNS routes
+- `web/src/lib/api.ts` — add DNS records API function
+- `web/src/routes/dns/+page.svelte` — new page
+- `web/src/routes/dns/+page.ts` — optional load function
+- Navigation component — add DNS link
+- Locale files — add i18n keys
+
+## Acceptance Criteria
+- DNS Records page accessible at /dns
+- Table shows all records with correct status
+- Filtering works: search text, consumer type, sync status
+- Only accessible/visible when wildcard DNS is disabled
+- Consumer names resolve correctly (project/stage for managed, proxy name for standalone)
+
+## Notes
+- Status computation: compare local dns_records table with Cloudflare ListRecords response
+- Cache Cloudflare response for a few seconds to avoid rate limiting on page load
+- Navigation link visibility tied to settings (may need a store or settings check)
+
+## Review Checklist
+- [ ] All tasks completed
+- [ ] Code follows project conventions
+- [ ] No unintended side effects
+- [ ] Build passes
+- [ ] Tests pass (new + existing)

+# Phase 6: DNS Sync & Reconciliation
+
+**Status:** ⬜ Not Started
+**Parent plan:** [PLAN.md](./PLAN.md)
+**Domain:** backend
+
+## Objective
+Implement reconciliation logic that compares expected DNS records (from active consumers)
+with actual Cloudflare records, and provides a sync endpoint to fix discrepancies.
+
+## Tasks
+
+- [ ] Task 1: Add `POST /api/dns/sync` endpoint
+  - Computes expected records from: active instances with proxy + standalone proxies
+  - Fetches actual records from Cloudflare via ListRecords
+  - Creates missing records (consumer exists, no CF record)
+  - Deletes orphaned records (CF record exists, no consumer) — only for records in dns_records table
+  - Updates dns_records table to reflect current state
+  - Returns sync report: created N, deleted N, already_synced N
+- [ ] Task 2: Add helper to compute expected records
+  - Query all instances where npm_proxy_id > 0 and status = "running" → extract FQDN
+  - Query all standalone proxies → extract domain
+  - Return list of expected FQDNs
+- [ ] Task 3: Add `DELETE /api/dns/records/{fqdn}` endpoint
+  - Manual deletion of a specific DNS record (for orphan cleanup)
+  - Calls provider.DeleteRecord + removes from dns_records
+- [ ] Task 4: Wire sync endpoint in `internal/api/dns.go` and router
+- [ ] Task 5: Add frontend sync button handler in DNS Records page
+  - Call POST /api/dns/sync
+  - Show sync report (toast or inline)
+  - Refresh records list after sync
+
+## Files to Modify/Create
+- `internal/api/dns.go` — add sync + delete endpoints
+- `internal/api/router.go` — register new routes
+- `internal/store/dns_records.go` — add helper queries (list consumers with FQDNs)
+- `web/src/lib/api.ts` — add syncDnsRecords(), deleteDnsRecord() functions
+- `web/src/routes/dns/+page.svelte` — wire sync button
+
+## Acceptance Criteria
+- POST /api/dns/sync creates missing and removes orphaned records
+- Sync report returned with counts
+- Manual delete endpoint works for individual records
+- Frontend sync button triggers reconciliation and refreshes view
+- Only records tracked in dns_records table are candidates for orphan deletion
+  (don't delete unrelated Cloudflare records)
+
+## Notes
+- Safety: only delete Cloudflare records that are tracked in our dns_records table
+  (never touch records we didn't create)
+- Rate limiting: Cloudflare API has rate limits, batch operations where possible
+- Expected records query needs to join instances + standalone_proxies with settings.domain
+

+- [ ] Code follows project conventions
+- [ ] No unintended side effects

-## Amendment Log
-
-### Amendment 1 — 2026-03-27
-
-**Type:** Added phase
-**What changed:** Added Phase 13: Frontend Polish & Modern UI after Phase 12
-**Why:** User wants modern look & feel with SVG icons and polished frontend
-**Impact on existing phases:** None — Phase 13 runs after all functionality is complete. Build/tests now required on Phase 13 (final) instead of Phase 12.
-
-### Amendment 2 — 2026-03-27
-
-**Type:** Modified phase
-**What changed:** Added Task 13 (EN/RU localization) to Phase 13: Frontend Polish & Modern UI
-**Why:** User wants bilingual support (English and Russian) in the dashboard
-**Impact on existing phases:** None — contained within Phase 13
-
-### Amendment 3 — 2026-03-27
-
-**Type:** Added phase
-**What changed:** Added Phase 14: Volumes & Environment — per-project env vars with per-stage overrides, volume mounts with shared/isolated modes, encryption for sensitive values, UI editor
-**Why:** Missing from feature planner phases but present in root PLAN.md Phase 4
-**Impact on existing phases:** Phase 14 becomes the final phase (build/tests required). Phase 13 (UI Polish) remains but no longer the final phase for build enforcement.
-
-### Amendment 4 — 2026-03-27
-
-**Type:** Modified phase
-**What changed:** Updated Phase 12 (Hardening) auth tasks to support two modes: Local auth (username/password in SQLite with bcrypt) and OAuth2/OIDC (Authentik or any OIDC provider with configurable discovery URL). Added auth settings UI, user management, OIDC callback flow.
-**Why:** Root PLAN.md was updated to require OAuth2/OIDC support alongside local auth
-**Impact on existing phases:** Phase 12 task count increased from 10 to 12. Added new files for auth module and login page.
-
-### Amendment 5 — 2026-03-27
-
-**Type:** Reordered phases
-**What changed:** Swapped Phase 13 (UI Polish) and Phase 14 (Volumes & Env). Volumes & Env is now Phase 13, UI Polish is now Phase 14 (final).
-**Why:** Volumes & Env adds new UI pages that need the polish pass. UI Polish must run last to cover all pages including auth (Phase 12) and volume/env editors (Phase 13).
-**Impact on existing phases:** Execution order changed. UI Polish (now Phase 14) remains the final phase with build/test enforcement.

-# Phase 1: Project Scaffold & SQLite Store
-
-**Status:** ✅ Complete
-**Parent plan:** [PLAN.md](./PLAN.md)
-**Domain:** backend
-
-## Objective
-Initialize the Go project, establish the directory structure, and implement the SQLite store with schema, migrations, and CRUD operations for all entities.
-
-## Tasks
-
-- [x] Task 1: Initialize Go module (`go mod init`), create directory structure per PLAN.md
-- [x] Task 2: Add core dependencies to go.mod (sqlite, chi, yaml, uuid, cron)
-- [x] Task 3: Define SQLite schema — tables for projects, stages, registries, settings, instances, deploys, deploy_logs
-- [x] Task 4: Implement store initialization with auto-migration (create tables if not exist)
-- [x] Task 5: Implement projects CRUD (Create, GetByID, GetAll, Update, Delete)
-- [x] Task 6: Implement stages CRUD (Create, GetByProjectID, Update, Delete)
-- [x] Task 7: Implement registries CRUD (Create, GetByID, GetAll, Update, Delete)
-- [x] Task 8: Implement settings Get/Update (single-row config pattern)
-- [x] Task 9: Implement instances CRUD (Create, GetByStageID, GetByID, Update, Delete, UpdateStatus)
-- [x] Task 10: Implement deploys CRUD (Create, GetByProjectID, GetRecent, GetByID) + deploy_logs append
-- [x] Task 11: Create `cmd/server/main.go` entry point (minimal — just opens DB, defers close)
-
-## Files to Modify/Create
-- `go.mod` — module definition and dependencies
-- `go.sum` — dependency checksums
-- `cmd/server/main.go` — entry point
-- `internal/store/store.go` — DB connection, schema, migrations
-- `internal/store/projects.go` — project queries
-- `internal/store/stages.go` — stage queries
-- `internal/store/registries.go` — registry queries
-- `internal/store/settings.go` — settings queries
-- `internal/store/instances.go` — instance queries
-- `internal/store/deploys.go` — deploy history queries
-
-## Acceptance Criteria
-- `go mod tidy` succeeds
-- All store CRUD functions are implemented with proper error handling
-- Schema covers all entities from the architecture plan
-- Entry point compiles (may not fully run until later phases wire everything)
-
-## Notes
-- Use `modernc.org/sqlite` for CGo-free SQLite
-- Use `go-chi/chi/v5` for routing (will be wired in Phase 8)
-- Settings table uses a single-row pattern (one row, upsert on update)
-- Instance status should be an enum-like string: "running", "stopped", "failed", "removing"
-- Deploy status: "pending", "pulling", "starting", "configuring_proxy", "health_checking", "success", "failed", "rolled_back"
-
-## Review Checklist
-- [ ] All tasks completed
-- [ ] Code follows Go conventions (gofmt, proper error returns)
-- [ ] No unintended side effects
-- [ ] Schema is normalized and covers all planned entities
-- [ ] CRUD functions handle not-found cases properly
-
-## Handoff to Next Phase
-
-### What was built
-
-- Go module initialized at `github.com/alexei/docker-watcher` with all core dependencies
-- Full directory structure created: `cmd/server/`, `internal/store/`, plus empty dirs for config, docker, npm, registry, deployer, health, notify, webhook, api, crypto
-- SQLite store with 7 tables: projects, stages, registries, settings, instances, deploys, deploy_logs
-- Auto-migration runs on store initialization (CREATE TABLE IF NOT EXISTS)
-- WAL mode, foreign keys, and busy timeout pragmas enabled
-- Settings table uses single-row pattern with `INSERT OR IGNORE` seed
-- Models extracted to `internal/store/models.go` for clean separation
-
-### Key files
-
-- `go.mod` — module definition with modernc.org/sqlite, chi, yaml, uuid, cron
-- `cmd/server/main.go` — entry point that creates data dir, opens store, defers close
-- `internal/store/store.go` — DB connection, pragmas, schema DDL, migration
-- `internal/store/models.go` — all entity structs (Project, Stage, Registry, Settings, Instance, Deploy, DeployLog)
-- `internal/store/projects.go` — full CRUD
-- `internal/store/stages.go` — full CRUD with bool-to-int conversion for SQLite
-- `internal/store/registries.go` — full CRUD
-- `internal/store/settings.go` — Get/Update (single-row upsert)
-- `internal/store/instances.go` — full CRUD + UpdateStatus
-- `internal/store/deploys.go` — Create, GetByID, GetByProjectID, GetRecent, UpdateDeployStatus, SetDeployInstanceID, AppendDeployLog, GetDeployLogs
-
-### Conventions established
-
-- UUIDs generated via `github.com/google/uuid` on Create operations
-- Timestamps stored as `datetime('now')` defaults in schema, `time.Now().UTC().Format("2006-01-02 15:04:05")` in Go code
-- All query errors wrapped with `fmt.Errorf` and `%w` for unwrapping
-- Not-found cases return descriptive error strings (not sentinel errors yet — can be refined)
-- Boolean fields stored as INTEGER (0/1) in SQLite, converted via `boolToInt` helper
-- JSON-encoded maps stored as TEXT for env and volumes fields
-
-### What Phase 2 needs to know
-
-- `store.New(dbPath)` returns a `*Store` that is ready to use — no additional init needed
-- The `settings` table is pre-seeded with a row (id=1) so `GetSettings` always works
-- Registry `token` and settings `npm_password` are stored as plain text — Phase 2 (Crypto) should add encryption/decryption around these fields
-- `go.sum` does not exist yet — run `go mod tidy` after Go is available to generate it

-- Quick Deploy: paste image URL → inspect → review defaults → deploy works end-to-end
-- All settings are editable and saved via API
-- Registry test connection shows success/failure
-- Credentials are masked in display (`••••••••`)
-- Webhook URL is shown with copy button and regenerate option
-- Form validation prevents bad submissions
-
-## Notes
-- Quick Deploy is the zero-config entry point — should be dead simple UX
-- Credential fields: show mask, edit replaces entirely (no partial edit)
-- Registry test: calls POST /api/registries/:id/test, shows connection result
-- Toast component: appears top-right, auto-dismiss after 5s, color-coded (green/red)
-
-## Review Checklist
-- [ ] All tasks completed
-- [ ] Quick deploy flow is intuitive (minimal clicks)
-- [ ] Credentials never shown in plaintext in UI
-- [ ] Form validation covers required fields and formats
-- [ ] Error states are handled with user-friendly messages

-# Phase 11: Frontend Embed & Real-Time Updates
-
-**Status:** Done
-**Parent plan:** [PLAN.md](./PLAN.md)
-**Domain:** fullstack
-
-## Objective
-Build SvelteKit to static files, embed into the Go binary with `go:embed`, serve from Go, and implement SSE for real-time deploy progress and instance status updates.
-
-## Tasks
-
-- [x] Task 1: Configure SvelteKit static adapter to output to `web/build/` (already configured)
-- [x] Task 2: Add `//go:embed web/build` directive in Go — `web.go` at project root
-- [x] Task 3: Create Go handler for serving embedded SPA — `internal/api/static.go` with SPA fallback
-- [x] Task 4: Implement SSE endpoint for deploy logs — `GET /api/deploys/:id/logs` (SSE + JSON fallback)
-- [x] Task 5: Implement SSE endpoint for instance status — `GET /api/events` streams instance status changes
-- [x] Task 6: Create event bus/broadcaster in Go — `internal/events/bus.go` with pub/sub channels
-- [x] Task 7: Frontend: connect to SSE for deploy progress — `connectDeployLogs()` in `web/src/lib/sse.ts`
-- [x] Task 8: Frontend: connect to SSE for instance status — global SSE in `+layout.svelte` via store
-- [x] Task 9: Handle SSE reconnection in frontend — exponential backoff with jitter in `connectSSE()`
-- [x] Task 10: Build script/Makefile — `make build` builds frontend then Go binary
-
-## Files to Modify/Create
-- `web/svelte.config.js` — already configured with static adapter outputting to `web/build/`
-- `web.go` — root-level embed directive (`//go:embed web/build`)
-- `internal/api/static.go` — embedded static file server with SPA fallback
-- `internal/api/sse.go` — SSE endpoints for deploy logs and instance events
-- `internal/events/bus.go` — event bus for publishing/subscribing to events
-- `web/src/lib/sse.ts` — SSE client helper with auto-reconnect
-- `web/src/lib/stores/instance-status.ts` — Svelte store for real-time instance status
-- `web/src/routes/+layout.svelte` — wired up global SSE connection for instance status
-- `Makefile` — build frontend + backend
-- `cmd/server/main.go` — wired embedded static serving and event bus
-- `internal/api/router.go` — added eventBus to Server, SSE routes
-- `internal/api/deploys.go` — removed old JSON stub, replaced by SSE handler
-- `internal/deployer/deployer.go` — added event publishing for deploy logs, status, instance status
-
-## Acceptance Criteria
-- `make build` produces a single Go binary with embedded frontend
-- Go binary serves the SvelteKit SPA on all non-API routes
-- Deploy progress streams in real-time via SSE
-- Instance status updates appear without page refresh
-- SSE reconnects automatically after network hiccups
-
-## Notes
-- `go:embed` requires the embedded directory to be relative to the Go source file
-- SPA fallback: any request that doesn't match `/api/*` gets `index.html`
-- Event bus: simple pub/sub with channels — no external dependency needed
-- SSE format: `data: {"type": "deploy_log", "payload": {...}}\n\n`
-- Keep SSE connections lightweight — use context cancellation for cleanup
-- WriteTimeout on HTTP server set to 0 to support long-lived SSE connections
-- Deploy logs endpoint serves both SSE (Accept: text/event-stream) and JSON (default)
-
-## Review Checklist
-- [x] All tasks completed
-- [x] Single binary serves both API and frontend
-- [x] SSE handles multiple concurrent clients (buffered channels, non-blocking publish)
-- [x] No goroutine leaks on SSE disconnect (context cancellation + Unsubscribe)
-- [x] Build process is reproducible (Makefile)
-
-## Handoff to Next Phase
-
-### What was implemented
-- **Event bus** (`internal/events/bus.go`): In-process pub/sub with topic filtering, buffered subscriber channels (64 events), non-blocking publish. Supports `EventDeployLog`, `EventInstanceStatus`, and `EventDeployStatus` event types.
-- **SSE endpoints**: `GET /api/deploys/{id}/logs` streams deploy logs with JSON fallback; `GET /api/events` streams global instance/deploy status changes.
-- **Static file serving**: `web.go` at project root embeds `web/build/`, `internal/api/static.go` serves SPA with fallback. Mounted via chi's `NotFound` handler.
-- **Frontend SSE client** (`web/src/lib/sse.ts`): `connectSSE()` with exponential backoff + jitter, `connectDeployLogs()` and `connectGlobalEvents()` convenience functions.
-- **Instance status store** (`web/src/lib/stores/instance-status.ts`): Svelte writable store updated by global SSE connection in `+layout.svelte`.
-- **Deployer integration**: `deployer.go` now publishes deploy log, deploy status, and instance status events via `EventPublisher` interface.
-
-### Key integration points for next phase
-- `events.Bus` is passed to both `api.NewServer` and `deployer.New`
-- `api.NewServer` now requires an `*events.Bus` parameter (6th arg before encKey)
-- `deployer.New` now requires an `EventPublisher` parameter (6th arg before encKey)
-- HTTP server `WriteTimeout` is 0 to support SSE
-- The `web.go` file at project root uses package name `dockerwatcher` (imported as `github.com/alexei/docker-watcher`)

-# Phase 12: Hardening
-
-**Status:** ⬜ Not Started
-**Parent plan:** [PLAN.md](./PLAN.md)
-**Domain:** backend
-
-## Objective
-Production hardening — blue-green deploys, promote flow, dashboard auth, graceful shutdown, structured logging, and config export.
-
-## Tasks
-
-- [ ] Task 1: Blue-green deploys — start new container, health check, swap NPM proxy, then stop old container (zero downtime)
-- [ ] Task 2: Promote flow — enforce `promote_from` for production deploys (only tags running in source stage are eligible)
-- [ ] Task 3: Local auth — username/password stored in SQLite (bcrypt hashed), login endpoint, session token (JWT or cookie)
-- [ ] Task 4: OAuth2/OIDC auth — integration with Authentik or any OIDC provider (configurable client ID, client secret, discovery URL)
-- [ ] Task 5: Auth settings UI — settings page to choose auth mode (local/OIDC), configure OIDC provider, manage local users
-- [ ] Task 6: Auth middleware — protect all /api/* routes except webhook; check session/JWT/OIDC token
-- [ ] Task 7: Graceful shutdown — handle SIGTERM/SIGINT, drain in-progress deploys, close DB, stop poller
-- [ ] Task 8: Structured logging — JSON logs with deploy context (project, stage, tag, instance ID)
-- [ ] Task 9: Config export — download current SQLite state as YAML (reverse of seed import)
-- [ ] Task 10: Dockerfile — multi-stage build (build frontend + Go, copy to minimal image)
-- [ ] Task 11: docker-compose.yml — production-ready compose file with volumes, network, env
-- [ ] Task 12: Final wiring review — ensure all services are properly initialized and shut down
-
-## Files to Modify/Create
-- `internal/deployer/bluegreen.go` — blue-green deploy strategy
-- `internal/deployer/promote.go` — promote flow logic
-- `internal/auth/local.go` — local auth (bcrypt password hashing, session tokens)
-- `internal/auth/oidc.go` — OAuth2/OIDC provider integration
-- `internal/auth/middleware.go` — auth middleware (session/JWT/OIDC token validation)
-- `internal/auth/models.go` — user model, auth settings, session store
-- `internal/api/auth.go` — auth API endpoints (login, logout, OIDC callback, user management)
-- `internal/config/export.go` — config export to YAML
-- `internal/logging/logger.go` — structured JSON logger
-- `internal/store/users.go` — user CRUD, auth settings persistence
-- `web/src/routes/login/+page.svelte` — login page
-- `web/src/routes/settings/auth/+page.svelte` — auth settings UI
-- `cmd/server/main.go` — graceful shutdown, structured logging, auth init
-- `Dockerfile` — multi-stage build
-- `docker-compose.yml` — production compose file
-
-## Acceptance Criteria
-- Blue-green: zero downtime during deploy (old container serves until new one is healthy)
-- Promote: production deploy only accepts tags from the specified source stage
-- Auth: unauthenticated requests to /api/* (except webhook) return 401
-- Graceful shutdown: in-progress deploys complete before exit
-- Logs are JSON-formatted with contextual fields
-- Config export produces valid YAML that could be re-imported
-- Docker image builds and runs correctly
-
-## Notes
-- Blue-green: keep old container running until new one passes health check, then swap NPM proxy and stop old
-- Auth has two modes configurable via settings:
-  - **Local auth**: username/password in SQLite (bcrypt hashed), JWT session tokens
-  - **OAuth2/OIDC**: integration with Authentik or any OIDC provider (client ID, secret, discovery URL)
-- First launch: create default admin user with configurable password via ADMIN_PASSWORD env var
-- OIDC flow: redirect to provider → callback → create/link local user → issue session
-- SIGTERM handling: use Go's `os/signal` + `context.WithCancel`
-- Structured logging: use `log/slog` (Go stdlib since 1.21)
-- Dockerfile: build stage with Node.js + Go, runtime stage with scratch/alpine
-- Phase 13 (UI Polish) and Phase 14 (Volumes & Env) follow this phase
-
-## Review Checklist
-- [ ] All tasks completed
-- [ ] Blue-green deploy handles rollback if new container fails
-- [ ] Auth doesn't block webhook endpoint
-- [ ] Graceful shutdown tested with concurrent deploys
-- [ ] Dockerfile produces a minimal image
-- [ ] docker-compose.yml matches the example in PLAN.md

-# Phase 14: Volumes & Environment
-
-**Status:** ⬜ Not Started
-**Parent plan:** [PLAN.md](./PLAN.md)
-**Domain:** fullstack
-
-## Objective
-Implement per-project environment variables with per-stage overrides, volume mounts with shared/isolated modes, sensitive env value encryption, and UI for managing both.
-
-## Tasks
-
-- [ ] Task 1: Extend store schema — add `stage_env` table for per-stage env overrides (stage_id, key, value, encrypted bool)
-- [ ] Task 2: Extend store schema — add `volumes` table for volume config (project_id, source, target, mode: shared|isolated)
-- [ ] Task 3: Implement store CRUD for stage env overrides (Create, GetByStageID, Update, Delete)
-- [ ] Task 4: Implement store CRUD for volumes (Create, GetByProjectID, Update, Delete)
-- [ ] Task 5: Encrypt sensitive env values (values marked as secret) using crypto.Encrypt before storage
-- [ ] Task 6: Merge env vars during deploy — project-level env + stage-level overrides, decrypt secrets
-- [ ] Task 7: Compute volume mounts during deploy — shared mode uses path as-is, isolated mode appends `/{stage}-{tag}/` to source
-- [ ] Task 8: Pass merged env vars and volume mounts to Docker container creation
-- [ ] Task 9: API endpoints — CRUD for stage env vars and project volumes
-- [ ] Task 10: Frontend — env var editor in project/stage settings (key/value pairs, secret toggle)
-- [ ] Task 11: Frontend — volume editor in project settings (source/target/mode)
-- [ ] Task 12: Frontend — per-stage env override UI showing inherited vs overridden values
-
-## Files to Modify/Create
-- `internal/store/stage_env.go` — stage env CRUD
-- `internal/store/volumes.go` — volume CRUD
-- `internal/store/store.go` — add new tables to schema
-- `internal/deployer/deployer.go` — merge env vars and compute volume mounts during deploy
-- `internal/docker/container.go` — accept volume mounts in ContainerConfig
-- `internal/api/stages.go` — add env var endpoints
-- `internal/api/projects.go` — add volume endpoints
-- `web/src/routes/projects/[id]/env/+page.svelte` — env var editor
-- `web/src/routes/projects/[id]/volumes/+page.svelte` — volume editor
-
-## Acceptance Criteria
-- Project-level env vars applied to all containers
-- Stage-level overrides replace project-level values for matching keys
-- Sensitive env values encrypted at rest, decrypted only during deploy
-- Shared volumes: all instances mount same host path
-- Isolated volumes: each instance gets `{source}/{stage}-{tag}/` subdirectory
-- UI allows managing env vars and volumes per project and per stage
-
-## Notes
-- Project `env` field already exists as JSON blob in the store — this phase may migrate to a proper table or keep JSON and add stage overrides separately
-- Volume `mode` is either "shared" or "isolated"
-- Isolated volume subdirectory is created automatically by Docker (bind mount creates parent dirs)
-- Sensitive env display: masked in UI, "Change" button pattern (same as credentials page)
-
-## Review Checklist
-- [ ] All tasks completed
-- [ ] Env merge logic is correct (stage overrides project)
-- [ ] Secret values never appear in plaintext in API responses
-- [ ] Volume paths are validated (no path traversal)
-- [ ] Isolated volume subdirectory naming is deterministic

-# Phase 2: Crypto & Config Seed Loader
-
-**Status:** ✅ Complete
-**Parent plan:** [PLAN.md](./PLAN.md)
-**Domain:** backend
-
-## Objective
-Implement AES-256 encryption for credential storage and the YAML seed config parser that imports into SQLite on first launch.
-
-## Tasks
-
-- [x] Task 1: Implement AES-256-GCM encrypt/decrypt functions using Go stdlib `crypto/aes` + `crypto/cipher`
-- [x] Task 2: Key derivation from ENCRYPTION_KEY env var (SHA-256 hash to get 32 bytes)
-- [x] Task 3: Define YAML config structs matching the seed format from PLAN.md
-- [x] Task 4: Implement YAML parser — read and validate seed file
-- [x] Task 5: Implement seed importer — checks if DB is empty, if so imports YAML into SQLite via store CRUD
-- [x] Task 6: Encrypt credential fields (registry tokens, NPM password) during import
-- [x] Task 7: Create `docker-watcher.example.yaml` with documented example config
-- [x] Task 8: Wire seed import into `cmd/server/main.go` startup sequence
-
-## Files to Modify/Create
-- `internal/crypto/crypto.go` — AES-256-GCM encrypt/decrypt
-- `internal/config/config.go` — YAML structs and parser
-- `internal/config/seed.go` — seed import logic (YAML → SQLite)
-- `docker-watcher.example.yaml` — example seed config
-- `cmd/server/main.go` — add seed import to startup
-
-## Acceptance Criteria
-- Encrypt then decrypt round-trips correctly
-- Different plaintexts produce different ciphertexts (random nonce)
-- YAML parsing handles all fields from the seed format
-- Seed import creates projects, stages, registries, and settings in SQLite
-- Credentials are encrypted before storage
-- Import is idempotent — skipped if DB already has data
-
-## Notes
-- ENCRYPTION_KEY is the only secret env var — everything else is encrypted in SQLite
-- Use GCM mode for authenticated encryption (integrity + confidentiality)
-- Seed import should be transactional — all or nothing
-- The example YAML should have placeholder values, not real credentials
-
-## Review Checklist
-- [x] All tasks completed
-- [x] Crypto uses secure practices (random nonce, GCM, no ECB)
-- [x] No hardcoded keys or secrets
-- [x] YAML parsing validates required fields
-- [x] Import is transactional
-
-## Handoff to Next Phase
-
-- `crypto.Encrypt(key, plaintext)` and `crypto.Decrypt(key, ciphertextHex)` handle AES-256-GCM encryption; ciphertext is hex-encoded with prepended nonce
-- `crypto.KeyFromEnv()` derives a `[32]byte` key from the `ENCRYPTION_KEY` env var via SHA-256
-- `crypto.EncryptIfNotEmpty(key, value)` is a convenience wrapper that passes through empty strings unchanged
-- `config.ImportSeed(db, seedPath)` is the single entry point for seed import — called from `main.go` at startup
-- Import is idempotent: skipped if the DB already has projects or registries
-- Import is transactional: all inserts happen within a single SQLite transaction (rollback on any failure)
-- Registry `token` and settings `npm_password` are now stored encrypted in SQLite — later phases that read these fields must decrypt with `crypto.Decrypt(key, value)`
-- `store.DB()` method was added to expose the underlying `*sql.DB` for transaction use
-- Seed file path is configurable via `SEED_FILE` env var (default: `./docker-watcher.yaml`)
-- YAML validation ensures: `global.domain` is required, every project needs `image`, project registry references must exist, stages need `tag_pattern`
-- `go.sum` still does not exist — run `go mod tidy` when Go toolchain is available

-## Objective
-Implement the Docker Engine API wrapper for container lifecycle management — pull images, inspect, create/start/stop/remove containers, and manage networks.
-
-## Tasks
-
-- [x] Task 1: Create Docker client wrapper with socket connection (`/var/run/docker.sock`)
-- [x] Task 2: Implement `PullImage(ctx, image, tag, authConfig)` — pull with optional registry auth
-- [x] Task 3: Implement `InspectImage(ctx, image)` — extract EXPOSE ports, HEALTHCHECK, labels

-- Use `github.com/docker/docker/client` SDK
-- Container names should be deterministic: `dw-{project}-{stage}-{tag-sanitized}`
-- All containers should be on the shared network (e.g., `staging-net`)
-- Port mapping: container's EXPOSE port → random host port (Docker auto-assigns)

-# Phase 4: NPM Client
-
-**Status:** ✅ Complete
-**Parent plan:** [PLAN.md](./PLAN.md)
-**Domain:** backend
-
-## Objective
-Implement the Nginx Proxy Manager API client — JWT authentication, CRUD for proxy hosts, and host lookup.
-
-## Tasks
-
-- [x] Task 1: Create NPM client struct with base URL, cached JWT token, and auto-refresh
-- [x] Task 2: Implement `Authenticate(ctx, email, password)` — POST /api/tokens, store JWT
-- [x] Task 3: Implement `CreateProxyHost(ctx, config)` — POST /api/nginx/proxy-hosts
-- [x] Task 4: Implement `UpdateProxyHost(ctx, id, config)` — PUT /api/nginx/proxy-hosts/{id}
-- [x] Task 5: Implement `DeleteProxyHost(ctx, id)` — DELETE /api/nginx/proxy-hosts/{id}
-- [x] Task 6: Implement `ListProxyHosts(ctx)` — GET /api/nginx/proxy-hosts
-- [x] Task 7: Implement `FindProxyHostByDomain(ctx, domain)` — search existing hosts by domain name
-- [x] Task 8: Define proxy host config struct (domain, forward host/port, SSL settings, etc.)
-- [x] Task 9: Handle JWT token expiry — re-authenticate automatically on 401
-
-## Files to Modify/Create
-- `internal/npm/client.go` — NPM API client, auth, HTTP helpers
-- `internal/npm/types.go` — request/response types for proxy hosts
-
-## Acceptance Criteria
-- Client authenticates and caches JWT
-- CRUD operations work for proxy hosts
-- Token refresh happens transparently on expiry
-- Proxy host config supports: domain, forward host, forward port, SSL (Let's Encrypt optional)
-- FindByDomain enables checking if a proxy already exists before creating
-
-## Notes
-- NPM API base: typically `http://npm:81/api`
-- Forward host for containers: use container name on the shared Docker network
-- Forward port: the container's internal port (from EXPOSE)
-- SSL: for staging, can be disabled; production may want Let's Encrypt
-- NPM credentials come from settings (encrypted in SQLite, decrypted at runtime)
-
-## Review Checklist
-- [ ] All tasks completed
-- [ ] JWT caching and refresh work correctly
-- [ ] HTTP errors are properly handled (not just status code, but response body)
-- [ ] No credentials logged or leaked in errors
-- [ ] Struct types match NPM API contract
-
-## Handoff to Next Phase
-
-### What was built
-
-- `internal/npm/types.go` — `ProxyHostConfig` (create/update input), `ProxyHost` (API response), `Meta`, auth types, and `boolInt` custom JSON type for NPM's 0/1 boolean fields.
-- `internal/npm/client.go` — Full NPM API client with JWT auth, auto-refresh, and CRUD.
-
-### Public API surface
-
-```go
-npm.New(baseURL string) *Client
-(*Client).Authenticate(ctx, email, password string) error
-(*Client).CreateProxyHost(ctx, config ProxyHostConfig) (ProxyHost, error)
-(*Client).UpdateProxyHost(ctx, id int, config ProxyHostConfig) (ProxyHost, error)
-(*Client).DeleteProxyHost(ctx, id int) error
-(*Client).ListProxyHosts(ctx) ([]ProxyHost, error)
-(*Client).FindProxyHostByDomain(ctx, domain string) (ProxyHost, bool, error)
-```
-
-### Key design decisions
-
-- JWT token is cached with expiry; auto-refreshed 5 minutes before expiry or on 401.
-- Credentials are stored in memory after `Authenticate` to enable transparent re-auth.
-- All HTTP errors include the response body text for debugging.
-- Credentials are never included in error messages.
-- `boolInt` type handles NPM API's inconsistent 0/1 vs true/false for boolean fields.
-- `FindProxyHostByDomain` does case-insensitive matching against all domain names.
-
-### Dependencies for next phase
-
-- Caller must provide decrypted NPM credentials (email + password from settings via `crypto.Decrypt`).
-- `ProxyHost.ID` (int) maps to `Instance.NpmProxyID` in the store for tracking.

-# Phase 5: Registry Client & Poller
-
-**Status:** ⬜ Not Started
-**Parent plan:** [PLAN.md](./PLAN.md)
-**Domain:** backend
-
-## Objective
-Implement the registry client interface with Gitea implementation, and the periodic tag polling scheduler.
-
-## Tasks
-
-- [ ] Task 1: Define `Registry` interface — `ListTags(ctx, image)`, `GetLatestTag(ctx, image, pattern)`
-- [ ] Task 2: Implement Gitea registry client — uses Gitea API to list container image tags
-- [ ] Task 3: Implement tag pattern matching — match tags against glob patterns (e.g., `dev-*`, `v*`)
-- [ ] Task 4: Implement tag comparison — detect new tags since last poll (store last-seen tag per project/stage)
-- [ ] Task 5: Create poller service — periodic scheduler using `robfig/cron`
-- [ ] Task 6: Poller logic — for each project/stage with polling enabled, check for new tags, trigger deploy if auto_deploy
-- [ ] Task 7: Add `last_polled_tag` field to instances or a new `poll_state` table in store
-- [ ] Task 8: Implement registry factory — create client based on registry type (gitea, future: github, dockerhub)
-
-## Files to Modify/Create
-- `internal/registry/registry.go` — interface definition + factory
-- `internal/registry/gitea.go` — Gitea registry implementation
-- `internal/registry/poller.go` — polling scheduler service
-- `internal/store/poll_state.go` — poll state persistence (optional, or extend existing tables)
-
-## Acceptance Criteria
-- Gitea client can list tags for a given image
-- Tag pattern matching correctly filters tags (glob-style)
-- Poller runs on configurable interval
-- New tags are detected by comparing against stored state
-- Registry factory returns correct client based on type
-
-## Notes
-- Gitea API: `GET /api/v1/packages/{owner}/container/{image}/tags` (or similar, verify against Gitea docs)
-- Auth: Bearer token from registry config
-- Polling interval comes from global settings
-- The poller is a fallback — webhooks are the primary detection mechanism (Phase 6)
-- GitHub Container Registry support is future work — just define the interface now
-
-## Review Checklist
-- [ ] All tasks completed
-- [ ] Interface is clean and minimal
-- [ ] Pattern matching handles edge cases (empty pattern, no tags)
-- [ ] Poller doesn't leak goroutines
-- [ ] Registry auth tokens handled securely

-# Phase 6: Webhook Handler
-
-**Status:** ✅ Complete
-**Parent plan:** [PLAN.md](./PLAN.md)
-**Domain:** backend
-
-## Objective
-Implement the secret UUID-based webhook endpoint that receives image push notifications from CI systems, with auto-creation of unknown projects.
-
-## Tasks
-
-- [x] Task 1: Implement webhook HTTP handler — `POST /api/webhook/:secret-uuid`
-- [x] Task 2: Validate incoming payload — extract image name and tag
-- [x] Task 3: Look up project by image name in store — match against configured project images
-- [x] Task 4: If known project: match tag to stage via tag patterns, determine if auto_deploy
-- [x] Task 5: If unknown project: auto-create project with defaults from image inspection (EXPOSE port, labels)
-- [x] Task 6: Generate and store webhook secret UUID in settings (on first launch)
-- [x] Task 7: Implement webhook URL regeneration (new UUID, invalidates old one)
-- [x] Task 8: Define webhook payload struct (`{"image": "registry/org/app:tag"}`)
-
-## Files to Modify/Create
-- `internal/webhook/handler.go` — webhook HTTP handler + payload parsing
-- `internal/webhook/matcher.go` — project/stage matching logic
-- `internal/webhook/autocreate.go` — auto-create project from unknown image
-
-## Acceptance Criteria
-- Valid webhook URL with correct UUID triggers processing
-- Invalid/missing UUID returns 404 (no information leak)
-- Known images are matched to projects and stages
-- Unknown images trigger auto-creation with sensible defaults
-- Webhook URL can be regenerated
-
-## Notes
-- Webhook URL format: `POST /api/webhook/d8f2a1e9-...`
-- No authentication needed beyond the secret UUID
-- Auto-created projects use: image EXPOSE port, "dev" as default stage, auto_deploy: true
-- The webhook handler calls into the deployer (Phase 7) — for now, define the interface/callback
-- Keep the handler thin — it matches and delegates
-
-## Review Checklist
-- [x] All tasks completed
-- [x] No information leak on invalid UUIDs
-- [x] Payload validation rejects malformed input
-- [x] Auto-creation uses safe defaults
-- [x] Handler is stateless (delegates to store/deployer)
-
-## Handoff to Next Phase
-
-### Exported API
-
-- `webhook.NewHandler(store, deployer, inspector)` — creates the HTTP handler
-- `webhook.Handler.Route()` — returns a `chi.Router` to mount at `/api/webhook`
-- `webhook.EnsureWebhookSecret(store)` — generates UUID on first launch, returns current secret
-- `webhook.RegenerateWebhookSecret(store)` — replaces secret with new UUID, invalidates old one
-- `webhook.ParseImageRef(ref)` — parses `registry/owner/name:tag` into components
-
-### Interfaces Defined
-
-- `webhook.DeployTriggerer` — `TriggerDeploy(ctx, projectID, stageID, imageTag) error` (mirrors `registry.DeployTriggerer`)
-- `webhook.ImageInspector` — `InspectImage(ctx, imageRef) (docker.ImageInfo, error)` (wraps `docker.Client`)
-
-### Integration Points
-
-- Mount the webhook router: `r.Mount("/api/webhook", webhookHandler.Route())`
-- Call `webhook.EnsureWebhookSecret(store)` at application startup to generate the secret on first launch
-- The deployer must implement `webhook.DeployTriggerer` (same signature as `registry.DeployTriggerer`)
-- The Docker client (`*docker.Client`) satisfies `webhook.ImageInspector` directly
-
-### Auto-Create Behavior
-
-- Unknown images create a project with name from image name, port from EXPOSE, healthcheck from image metadata
-- A default "dev" stage is created with `tag_pattern: "*"`, `auto_deploy: true`, `max_instances: 1`
-- If image inspection fails (not pulled locally), project is created with port=0 and empty healthcheck
-
-### Tag Matching
-
-- Uses `path.Match` (glob semantics) — same approach as the registry poller
-- Stages are checked in name-sorted order; first matching stage wins

-# Phase 7: Deployer & Health Checker
-
-**Status:** ✅ Complete
-**Parent plan:** [PLAN.md](./PLAN.md)
-**Domain:** backend
-
-## Objective
-Implement the core deployment orchestrator: pull → start container → configure NPM proxy → health check → success/rollback. Plus multi-instance support and notifications.
-
-## Tasks
-
-- [x] Task 1: Define deployer service struct — depends on Docker client, NPM client, store, notifier
-- [x] Task 2: Implement deploy flow: pull image → create container → start → connect to network → configure proxy → health check
-- [x] Task 3: Implement subdomain generation per convention: `stage-{stage}-{project}` for default, `stage-{stage}-{project}-{tag}` for specific
-- [x] Task 4: Sanitize tags for DNS (dots → dashes, lowercase, truncate)
-- [x] Task 5: Implement health checker — HTTP GET to `http://container:{port}{healthcheck_path}` with retries and timeout
-- [x] Task 6: Implement rollback on health check failure — remove new container, delete NPM proxy host, update instance status
-- [x] Task 7: Implement multi-instance support — multiple tags of same project/stage can run simultaneously
-- [x] Task 8: Implement max_instances enforcement — remove oldest instance when limit reached
-- [x] Task 9: Implement notification webhook — POST to configured URL on deploy success/failure
-- [x] Task 10: Create deploy history records in store (status, timestamps, logs)
-- [x] Task 11: Implement deploy log streaming — append log entries during deploy for real-time visibility
-

-- `internal/deployer/rollback.go` — rollback logic
-- `internal/health/checker.go` — HTTP health checker with retries
-- `internal/notify/notifier.go` — webhook notification sender
-
-## Acceptance Criteria
-- Full deploy flow works end-to-end (pull → proxy → health check)
-- Failed health checks trigger automatic rollback
-- Multi-instance: deploying a new tag doesn't stop existing instances
-- max_instances removes oldest instance when exceeded
-- Notifications fire on success and failure
-- Deploy history is recorded with status and timestamps
-
-## Notes
-- Health check: 3 retries, 5s between retries, 10s timeout per attempt (configurable later)
-- Subdomain pattern comes from global settings
-- Notifications are fire-and-forget (don't block deploy on notification failure)
-- Deploy logs should be structured entries (timestamp + message) for SSE streaming later
-- The deployer is the central orchestrator — webhook handler and poller both call into it
-
-## Review Checklist
-- [ ] All tasks completed
-- [ ] Rollback cleans up ALL resources (container, proxy, instance record)
-- [ ] No goroutine leaks
-- [ ] Error handling at every step of the deploy flow
-- [ ] Subdomain generation produces valid DNS names

-## Objective
-Build the SvelteKit frontend with the dashboard overview and project detail views — project list, instance status, controls, and deploy history.
-
-## Tasks
-
-- [x] Task 1: Initialize SvelteKit project in `web/` directory with TypeScript, static adapter
-- [x] Task 2: Set up Tailwind CSS v4 with @tailwindcss/vite plugin
-- [x] Task 3: Create shared API client (`lib/api.ts`) — typed fetch wrapper for all backend endpoints
-- [x] Task 4: Define TypeScript types (`lib/types.ts`) — Project, Stage, Instance, Deploy, Registry, Settings
-- [x] Task 5: Create layout with navigation — sidebar with Dashboard, Projects, Deploy, Settings links
-- [x] Task 6: Dashboard page (`routes/+page.svelte`) — project overview cards with instance counts, status indicators
-- [x] Task 7: Projects list page (`routes/projects/+page.svelte`) — all projects with quick stats, "Add Project" button
-- [x] Task 8: Project detail page (`routes/projects/[id]/+page.svelte`) — stages, instances per stage, controls
-- [x] Task 9: Instance controls — Stop, Start, Restart, Remove buttons with confirmation dialogs
-- [x] Task 10: Deploy history section in project detail — recent deploys with status, timestamp, tag
-- [x] Task 11: "Deploy new version" dropdown — list available tags from registry, trigger deploy
-- [x] Task 12: Create reusable components: StatusBadge, InstanceCard, ProjectCard, ConfirmDialog
-
-## Files to Modify/Create
-- `web/package.json` — SvelteKit project config
-- `web/svelte.config.js` — SvelteKit config with static adapter
-- `web/vite.config.ts` — Vite config with API proxy for dev

-## Acceptance Criteria
-- SvelteKit project builds to static output
-- Dashboard shows all projects with live status
-- Project detail shows stages, instances, and controls
-- Instance controls trigger correct API calls
-- Deploy dropdown fetches and displays available tags
-- UI is responsive and clean
-
-## Notes
-- SvelteKit static adapter for embedding in Go binary
-- API proxy in vite.config.ts for dev: proxy `/api` to `http://localhost:8080`
-- Use SvelteKit's `fetch` for SSR-compatible data loading
-- Status colors: green=running, yellow=starting, red=failed, gray=stopped
-- Keep components small and reusable
-
-## Review Checklist
-- [ ] All tasks completed
-- [ ] TypeScript types match backend API response format
-- [ ] API client handles errors gracefully with user feedback
-- [ ] No hardcoded API URLs (use relative paths)
-- [ ] Components are reusable and well-structured
-
-## Handoff to Next Phase
-
-Phase 9 is complete. All 14 files have been created in the `web/` directory:
-
-**Configuration files:**
-- `web/package.json` — Svelte 5, SvelteKit 2, Tailwind CSS v4, static adapter, TypeScript
-- `web/svelte.config.js` — Static adapter with SPA fallback (`index.html`)
-- `web/vite.config.ts` — Tailwind v4 vite plugin + `/api` proxy to `localhost:8080`
-- `web/tsconfig.json` — Strict TypeScript, bundler module resolution
-- `web/src/app.html` — Base HTML shell
-- `web/src/app.css` — Tailwind v4 import
-- `web/src/routes/+layout.ts` — Disables SSR, enables prerender for static adapter
-
-**Core library:**
-- `web/src/lib/types.ts` — All TypeScript types matching Go backend models exactly (Project, Stage, Instance, Deploy, DeployLog, Registry, Settings, ApiEnvelope)
-- `web/src/lib/api.ts` — Full typed API client covering all endpoints (projects, instances, deploys, registries, settings). Unwraps envelope, throws `ApiError` on failure.
-
-**Components (Svelte 5 runes):**
-- `StatusBadge.svelte` — Color-coded status pill (green/yellow/red/gray/blue)
-- `ConfirmDialog.svelte` — Modal with danger/primary variants
-- `InstanceCard.svelte` — Instance display with stop/start/restart/remove controls
-- `ProjectCard.svelte` — Project summary card for dashboard grid
-
-**Pages:**
-- `+layout.svelte` — Sidebar navigation (Dashboard, Projects, Deploy, Settings)
-- `routes/+page.svelte` — Dashboard with stats cards and project grid
-- `routes/projects/+page.svelte` — Project table with inline add-project form
-- `routes/projects/[id]/+page.svelte` — Full project detail: stages, instances, deploy form, deploy history
-
-**Key decisions:**
-- Used Svelte 5 runes (`$state`, `$derived`, `$effect`, `$props`) throughout
-- Tailwind CSS v4 with `@tailwindcss/vite` plugin (no PostCSS config needed)
-- Client-side only rendering (SSR disabled) for static adapter compatibility
-- API client uses relative `/api/` paths — works in both dev (vite proxy) and prod (embedded)
-- All API calls include loading spinners and error states with retry buttons
-
-**Ready for Phase 10:** Settings pages, Quick Deploy page, and remaining UI routes. The API client already includes all endpoint wrappers needed.
