# Tasks — Add @suaveplan/delivery-tracking

## 1. Spec authoring

- [x] 1.1 Read `../suaveplan/enterprise/delivery-tracking.md` end-to-end
- [x] 1.2 Confirm `openspec/specs/delivery-tracking/spec.md` does not yet exist
- [x] 1.3 Read `openspec/AGENTS.md` Sections 0a, 2a, 6a, 7, 12, 13, 14
- [x] 1.4 Draft `proposal.md` from `openspec/templates/proposal.md`
- [x] 1.5 Fill in `## Source mapping` table — every requirement cites a line range OR is justified
- [x] 1.6 Draft `specs/delivery-tracking/spec.md` from `openspec/templates/spec-delta.md`
- [x] 1.7 Every requirement carries a `**Verified by:**` line naming concrete `it(...)` titles

## 2. Implementation

- [x] 2.1 Types in `src/types/delivery-tracking.types.ts`
- [x] 2.2 `DeliveryTrackingError` + `defineCodes` registry
- [x] 2.3 OTel counter set in `src/otel/instruments.ts`
- [x] 2.4 `DeliveryEventStore` interface + `InMemoryDeliveryEventStore` + `computeStats` helper
- [x] 2.5 `SurrealDeliveryEventStore` using positional SurQL with typed-error wrapping
- [x] 2.6 `DeliveryTracker` with Zod boundary, lifecycle dedupe, typed `EventBus`, injectable `Clock`/`IdGenerator`
- [x] 2.7 `DeliveryAggregator` with campaign/contact/time-series APIs
- [x] 2.8 `TrackingPixelGenerator` + `TrackingLinkWrapper` sharing a `token-codec` module
- [x] 2.9 `WebhookEventParser` with `sendgrid`/`mailgun`/`ses`/`generic` parsers and a runtime registry
- [x] 2.10 Package root barrel re-exports every public symbol via explicit named exports
- [x] 2.11 Package `vite.config.ts`, `vitest.config.ts`, `tsconfig.lib.json`, `tests/setup/polyfills.ts`

## 3. Tests

- [x] 3.1 Unit tests in each feature directory
- [x] 3.2 OTel counter assertions via real `InMemoryMetricExporter` + `MeterProvider`
- [x] 3.3 Every `it(...)` carries `{ timeout: 5000 }`
- [x] 3.4 No `vitest` / `bun:test` direct imports — every test imports from `@suaveplan/testing/runner`

## 4. Documentation

- [x] 4.1 Sibling `.md` for every implementation `.ts` (≥200 words, basic + advanced examples, full API reference)
- [x] 4.2 `README.md` links every co-located `.md` under `## Modules`

## 5. Pre-archive verification (the 5-gate triple)

- [ ] 5.1 `bun run check` — Biome clean
- [ ] 5.2 `bunx turbo lint typecheck test --filter=@suaveplan/delivery-tracking`
- [ ] 5.3 `bunx turbo test:coverage --filter=@suaveplan/delivery-tracking` — 100/100/100/100
- [ ] 5.4 `bun scripts/openspec-conformance.ts @suaveplan/delivery-tracking`
- [ ] 5.5 `bunx turbo build --filter=@suaveplan/delivery-tracking`

## 6. Pre-archive 9-row checklist

- [ ] 6.1 Generics threaded; injectable `Clock`/`IdGenerator` pinned via tests
- [ ] 6.2 Zod schemas wired at the tracker boundary
- [ ] 6.3 Every error code thrown by ≥1 production path (`INVALID_INPUT`/`INVALID_TOKEN`/`UNSUPPORTED_PROVIDER`/`STORE_FAILURE`/`QUERY_FAILURE`)
- [ ] 6.4 Strict-mode behaviours (`exactOptionalPropertyTypes`, `noUncheckedIndexedAccess`) honoured
- [ ] 6.5 OTel instruments emitted and asserted with real `MeterProvider`
- [ ] 6.6 Lifecycle dedupe tested (opened + delivered dedupe; clicked + sent allowed to repeat)
- [ ] 6.7 No retroactive ticking — boxes 5.* and 6.* tick only after the gates pass
- [ ] 6.8 No `export *` in feature barrels (all feature `index.ts` files use explicit named exports)
- [ ] 6.9 No direct `vitest` / `bun:test` imports (every test file imports from `@suaveplan/testing/runner`)

## 7. Archive

- [ ] 7.1 Fold `specs/delivery-tracking/spec.md` into `openspec/specs/delivery-tracking/spec.md`
- [ ] 7.2 Move `openspec/changes/add-delivery-tracking/` → `openspec/archive/2026-05-19-add-delivery-tracking/`
