# Tasks — Slim @suaveplan/currency-providers

## Spec-completeness preflight (AGENTS.md §12a)

- [x] Numbered checklist of every `### Requirement` and `#### Scenario`
      drafted in `specs/currency-providers/spec.md` (10 requirements
      kept/added; see `./specs/currency-providers/spec.md`).

## Remove concrete provider modules

- [x] Delete `src/providers/ecb/`
- [x] Delete `src/providers/fixer/`
- [x] Delete `src/providers/open-exchange-rates/`
- [x] Delete `src/providers/binance/`
- [x] Delete `src/providers/coingecko/`
- [x] Delete `src/providers/coinmarketcap/`
- [x] Delete `src/providers/cryptocompare/`
- [x] Delete `src/providers/kraken/`
- [x] Delete `src/providers/virtual/`
- [x] Delete now-empty `src/providers/` directory
- [x] Drop the 9 `./providers/<name>/<name>` subpath exports from
      `package.json`
- [x] Drop `@suaveplan/currency` and `@suaveplan/money` from `dependencies`
      iff no remaining surface needs them — actually `@suaveplan/currency`
      stays (registry stores `CurrencyProvider` instances from that pkg)
      and `@suaveplan/money` drops (only the deleted `VirtualCurrencyProvider`
      used `registerCurrency`).

## Add slim-core surface

- [x] Add `PROVIDER_NOT_REGISTERED` + `PROVIDER_ALREADY_REGISTERED` codes to
      `CURRENCY_PROVIDER_CODES` (`src/error-codes/error-codes.ts`)
- [x] Build `src/registry/registry.ts` — `CurrencyProviderRegistry` class with
      `register` / `get` / `has` / `list` / `unregister`
- [x] Build `src/registry/registry.md` (sibling doc, ≥200 words)
- [x] Build `src/registry/registry.test.ts` — covers every method, both
      registry error codes, `list()` sort determinism
- [x] Build `src/factory/factory.ts` — `defineCurrencyProvider` factory
- [x] Build `src/factory/factory.md`
- [x] Build `src/factory/factory.test.ts`
- [x] Build `src/http/http.ts` — `httpRequest` + `composeAbortSignal`
- [x] Build `src/http/http.md`
- [x] Build `src/http/http.test.ts` — happy path, HTTP_ERROR on non-2xx,
      header forwarding, caller-signal abort, timeout-signal abort, both
      signals abort, `composeAbortSignal` all four combinations
- [x] Update `src/error-codes/error-codes.test.ts` to assert the two new
      codes and prove they are reachable from registry call sites
- [x] Update `src/index.ts` — explicit named barrel with new exports + drop
      removed provider exports
- [x] Update `package.json` `exports` map: 5 subpaths total (`.`,
      `./error-codes/error-codes`, `./types/configs`, `./registry/registry`,
      `./factory/factory`, `./http/http`)
- [x] Update `tests/dep-graph.test.ts` to match the new subpath list (or
      delete the per-subpath assertions and replace with a check that
      every `<feature>/index.ts` is referenced from a subpath export)
- [x] Update `vite.config.ts` external list (drop `@suaveplan/money`)

## Documentation

- [x] Update `README.md` Modules + Provider summary sections to describe the
      slim core (registry / factory / httpRequest / shared types) and link
      to the future sibling packages
- [x] Confirm every `.ts` in `src/` has a sibling `.md` (the §13 step-5
      grep returns zero)

## Pre-archive gates (AGENTS.md §13)

- [ ] Step 0 — spec reconciliation: every `### Requirement` and
      `**Verified by:**` resolves to a real file + verbatim test name
- [ ] Step 1 — `bunx turbo lint typecheck test --filter=@suaveplan/currency-providers`
      and `bun run check` both green
- [ ] Step 2 — `bunx turbo test:coverage --filter=@suaveplan/currency-providers`
      reports 100/100/100/100 via istanbul
- [ ] Step 3 — `bunx turbo build --filter=@suaveplan/currency-providers` green
- [ ] Step 4 — banned-pattern grep returns zero
- [ ] Step 4a — barrel-shape grep returns zero
- [ ] Step 4b — test-runner-import grep returns zero
- [ ] Step 5 — missing-`.md` grep returns zero
- [ ] Step 6 — README present
- [ ] Step 7 — bare-version grep returns zero
- [ ] Step 8 — subpath-export count = 5 (matches feature module count)
- [ ] Step 9 — security-scan grep returns zero
- [ ] Step 10 — dependent sweep
      (`bunx turbo test --filter=...@suaveplan/currency-providers`)

## Root-doc refresh (AGENTS.md §13b)

- [ ] Re-run `bun scripts/folder-reorg/generate-manifest.ts` to refresh
      `MANIFEST.md`
- [ ] Re-run `bun scripts/generate-missing.ts` to refresh `MISSING.yml`
- [ ] Update `STATUS.md` row for `@suaveplan/currency-providers` to describe
      the slim shape
- [ ] Update `SUMMARY.md` row for `@suaveplan/currency-providers` likewise
- [ ] `bunx markdownlint-cli2 --fix` across touched root + change files

## Archive (AGENTS.md §14)

- [ ] Fold `specs/currency-providers/spec.md` into
      `openspec/specs/currency-providers/spec.md` (apply REMOVED + ADDED
      to the canonical spec landed by the 2026-05-17 change)
- [ ] Move `openspec/changes/slim-currency-providers/` →
      `openspec/archive/2026-05-17-slim-currency-providers/`
