# Changelog

## 0.2.0 (2026-07-20)

Architecture deepening refactor — 4 structural improvements from architecture review, plus PR review fixes.

### Changed

- **models.ts split into three modules**: `thinking.ts` (reasoning-effort maps + translation interfaces), `catalog.ts` (static model data), `discovery.ts` (fetch/parse/resolveModels). `models.ts` is now a barrel re-export. Data edits (pricing, vision input, new slugs) now touch only `catalog.ts` instead of the old 445-line hotspot.
- **`walkAuthPaths` collapsed into `resolveApiKey`**: removed the generic `<T>`/extract seam that had only one caller. Walk logic inlined; injectable I/O handles preserved.
- **`sanitizeApiKey` moved from `env.ts` to `oauth.ts`**: its only caller. Deleted dead `buildEndpointUrl` + `DEFAULT_ENDPOINT` helpers.
- **Tests split along module seam**: `models.test.ts` split into `catalog.test.ts` (10 tests), `discovery.test.ts` (10 tests), and reduced `models.test.ts` (4 barrel tests). 102 tests across 11 files.

### Fixed

- **Non-chat models now consistently available**: `resolveModels` appends static non-chat models (Wan, HappyHorse) to remote results so they appear regardless of fetch success.
- **`thinkingMapFor` wired into discovery**: `parseRemoteModel` now calls `thinkingMapFor()` instead of inline ternary for map selection. Single rule, two call sites.
- **`CONTROL_CHARS_RE` simplified**: from verbose `new RegExp(String.fromCharCode(...))` to `/[\x00-\x1F\x7F]/g`.
- **Self-dependency removed**: `"pi-qwencloud-provider"` in `dependencies` was a scaffold artefact.
- **Section rulers added to `thinking.ts`**: visual consistency with the rest of the codebase.

### Internal

- Comprehensive `.planning/codebase/` codemap (7 documents) refreshed post-refactor.

## 0.1.3

Model capability corrections based on official QwenCloud docs audit (docs.qwencloud.com).

### Fixed

- **Vision input support for qwen3.8-max-preview, qwen3.7-plus, qwen3.6-flash** — changed `input` from `["text"]` to `["text", "image"]`. Official docs list "visual understanding" as a capability for these three models. Verified end-to-end: qwen3.7-plus correctly describes images via the OpenAI-compatible vision API.
- **README: qwen3.6-flash thinking levels** — corrected from "off (no reasoning)" to "low / medium / high". qwen3.6-flash supports reasoning per official docs and our code already had `DEFAULT_THINKING_LEVEL_MAP`.

## 0.1.2

Critical bug fixes found during real-world pi testing.

### Fixed

- **Provider name renamed from `qwencloud` to `qw`** — avoids model name clashes with the clinepass provider (both have `deepseek-v4-pro` and `glm-5.2`). pi's model resolution checks all providers; the short unique name disambiguates. Users reference models as `qw/qwen3.7-plus`, `qw/deepseek-v4-pro`, etc.
- **Model IDs are now bare API names** — dropped the `qwencloud/` prefix from internal model IDs (e.g., `qwencloud/deepseek-v4-pro` → `deepseek-v4-pro`). pi scopes via the provider name; the API gets the correct bare model name.
- **`supportsDeveloperRole: false`** — QwenCloud rejects the `developer` role (400 error). pi now sends `system` instead, matching the ClinePass pattern.

## 0.1.1

Bug fixes based on research findings and API smoke testing.

### Fixed

- DeepSeek V4 Pro: `xhigh` now maps to `"max"` instead of `"high"` (chat API only accepts `high`/`max`)
- `fetchRemoteModels` now excludes non-chat model families (`wan`, `happyhorse`, `qwen-image`) from dynamic discovery
- Pricing corrections: `qwen3.6-flash` (0.25/1.50), `glm-5.2` (1.10/3.85); `deepseek-v4-pro` flagged as unconfirmed estimate
- `isNonChatModel` filter now uses case-insensitive matching

## 0.1.0

Initial release — QwenCloud provider for pi.

### Models

- **Text/Chat**: qwen3.8-max-preview, qwen3.7-plus, qwen3.7-max, qwen3.6-flash, deepseek-v4-pro, glm-5.2
- **Image Generation**: wan2.7-image, wan2.7-image-pro
- **Video Generation**: happyhorse-1.1-i2v, happyhorse-1.1-t2v, happyhorse-1.1-r2v

### Features

- OpenAI-compatible chat completions via `QWENCLOUD_API_KEY`
- `reasoning_effort` support (low/medium/high/xhigh) — Qwen family uses `enable_thinking`/`thinking_budget`; DeepSeek/GLM use `reasoning_effort` (`high`/`max`). There is **no** `none` value on the chat/completions path; `off` omits the param (model default)
- Dynamic model discovery from `/models` endpoint with static fallback
- Simple API-key login flow (no OAuth required)
- User-friendly error classification: 401 (invalid key), 403 (plan expired), 429 (rate limited), quota exceeded
- Non-chat models (Wan, HappyHorse) filtered from dynamic discovery
- 86 unit tests + E2E smoke tests

> **Model availability**: All catalog slugs (qwen3.8-max-preview, qwen3.7-plus/max, qwen3.6-flash, deepseek-v4-pro, glm-5.2, wan2.7-image[-pro], happyhorse-1.1-i2v/t2v/r2v) match the official QwenCloud Token Plan model list. If a request returns `404 model_not_found`, it is a transient plan/API issue — re-run `pi /login` and confirm your plan status at home.qwencloud.com.
