opencode-free-router v0.1.2

• Split the plugin's server closure into named factories

opencode-free-router v0.1.1

• The code is now TypeScript, type-checked by TypeScript 7 in strict mode, and still ships as source
  with no build step: opencode loads plugin.ts, and Node or Bun runs rank.mts. Node 22.18 or
  newer is now required (Bun works as before); install.sh refuses an older node on PATH,
  since the plugin starts the ranker with it.

• Upgrading with install.sh replaces plugin.js, lib.mjs and rank.mjs with the new files and
  points the plugin entry of an existing free.jsonc at ./plugin.ts. Nothing else in your files
  changes.

• config.json, pins.json, state.json, the ranking and every API response are now checked field
  by field when read. A value of the wrong type in config.json keeps its default, and malformed
  entries in pins.json are skipped, where before they could break a ranking run.

• Four more free providers on the freeTier allowlist, each checked against the provider's own terms
  rather than a price of 0: Z.AI and Zhipu AI (the free GLM Flash models, same key for both
  endpoints), ModelScope (all of its inference is free, with a 2,000 requests a day quota) and
  Mistral (Devstral Small, Codestral and Mistral Small on the free Experiment plan, matched by name
  since the catalog prices them). providers.env.example and the README list their keys and caveats.
  Cloudflare Workers AI, Vercel AI Gateway, Hugging Face and the OpenRouter clone gateways were left
  out on purpose, and the README says why.

• A new test keeps templates/config.example.json in step with the shipped defaults.

• A 402 Payment Required now fails over like a removed model (24-hour cooldown) instead of being
  ignored, so a free-plan account that asks for a model it cannot pay for moves on instead of
  retrying a request that can never succeed.

• Tests now run rank.mjs as a CLI (stubbed network, fake opencode) and plugin.js against a
  fake opencode client, bringing line coverage of src/ to 100%. No behavior change; an
  unreachable API-key check in rank.mjs was removed.

• The bb agent registered by install.sh --bb now lists its model with opencode-free --list-models, which prints free/auto without starting opencode. Listing it through opencode
  (an ACP probe, or opencode models free) sometimes failed, for example with "database is locked"
  while other opencode processes were running, and bb then showed only "Agent default" until a
  later refresh happened to succeed. Re-registering keeps fields you set on the entry by hand, such
  as icon, and a failed registration no longer prints the other agents' env values.

opencode-free-router v0.1.0

First public release.

• free/auto model for opencode: the plugin swaps it for the best-ranked free model and keeps it
  for the whole session.
• Ranking from LMArena (agent, webdev, text) and Artificial Analysis (coding, agentic,
  intelligence), with stealth-model detection via OpenRouter and pins.json overrides.
• Failover on quota, rate limit, removal or refusal: cooldown, next-ranked model, automatic
  continue (a visible thread message under bb).
• Free providers are an explicit allowlist (Zen, OpenRouter and NVIDIA 0-priced models; Groq,
  Cerebras and Google free tiers). Subscription plans that report price 0 are never used.
• The plugin refreshes the ranking itself when it is older than 6 hours.
• install.sh / uninstall.sh, the opencode-free wrapper, and optional bb agent
  registration (--bb).
