# Tasks — Ship @suaveplan/emailer

## 1. Spec authoring

- [x] 1.1 Read `../suaveplan/enterprise/emailer.md` end-to-end
- [x] 1.2 No prior `openspec/specs/emailer/spec.md` exists
- [x] 1.3 Read `openspec/AGENTS.md` Sections 13 and 14
- [x] 1.4 Draft `proposal.md`
- [x] 1.5 Fill in `## Source mapping`
- [x] 1.6 Draft `specs/emailer/spec.md`
- [x] 1.7 Every requirement carries a `**Verified by:**` line

## 2. Implementation

- [x] 2.1 `src/error-codes.ts` — `defineCodes("EMAILER", [...])`, 12 codes, typed `EmailerError`
- [x] 2.2 `src/schemas/schemas.ts` — Zod schemas for every option bundle and message
- [x] 2.3 `src/types/emailer.types.ts` — `EmailMessage`, `EmailTransport`, hook contexts, stats
- [x] 2.4 `src/otel/metrics.ts` — counters / histogram / `refreshEmailerMeters`
- [x] 2.5 `src/core/validate/validate.ts` — address-formatting + validation helpers
- [x] 2.6 `src/core/retry/retry.ts` — deterministic retry helper (linear / exponential, AbortSignal)
- [x] 2.7 `src/core/email-service/email-service.ts` — `EmailService` class
- [x] 2.8 `src/core/email-service/base-email-transport.ts` — abstract helper
- [x] 2.9 `src/transports/dummy/dummy-transport.ts`
- [x] 2.10 `src/transports/smtp/smtp-transport.ts` + `smtp-client-like.types.ts`
- [x] 2.11 `src/transports/gmail-rest/gmail-rest-transport.ts`
- [x] 2.12 `src/fakes/fake-smtp-client.ts`
- [x] 2.13 `src/index.ts` — explicit named re-exports, side-effect import of `./error-codes.js`

## 3. Tests

- [x] 3.1 Unit tests at every feature directory, all importing from `@suaveplan/testing/runner`
- [x] 3.2 `src/emailer.spec-conformance.test.ts` — type-level, OTel, lifecycle pins
- [x] 3.3 `tests/dep-graph.test.ts`, `tests/no-disallowed.test.ts`
- [x] 3.4 Every `it(...)` carries `{ timeout: 5000 }`

## 4. Documentation

- [x] 4.1 Sibling `.md` for every implementation `.ts` (≥200 words)
- [x] 4.2 README at package root linking every co-located `.md`

## 5. Pre-archive 5-gate triple

- [x] 5.1 `bun run check`
- [x] 5.2 `bunx turbo lint typecheck test --filter=@suaveplan/emailer`
- [x] 5.3 `bunx turbo test:coverage --filter=@suaveplan/emailer` (100/100/100/100)
- [x] 5.4 `bun scripts/openspec-conformance.ts @suaveplan/emailer`
- [x] 5.5 `bunx turbo build --filter=@suaveplan/emailer`

## 6. Pre-archive 9-row checklist

- [x] 6.1 Generics threaded (`EmailService<TTransport>`); `expectTypeOf` on every literal-type claim
- [x] 6.2 Zod schemas wired at every declared boundary
- [x] 6.3 Every error code in `EMAILER_CODES` thrown by at least one production path
- [x] 6.4 Strict-mode behaviours tested both on and off (validation, retry abort)
- [x] 6.5 OTel instruments emitted from production paths and asserted with real in-memory `MeterProvider`
- [x] 6.6 Lifecycle dedup tested (verify-fail short-circuit, queue-not-configured guard)
- [x] 6.7 No retroactive tick
- [x] 6.8 No `export *` in any non-root barrel
- [x] 6.9 No direct `vitest` / `bun:test` imports in test files

## 7. Archive

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