july_lu 47c2382467 gateway: a gateway key can be held to some accounts (#905, LCorleone) — a key could burn any account a provider had: two coding plans of one vendor, and a key given to someone had them both. A key now keeps an optional list of accounts and keys (caller-keys.json "accounts", none = every account, so older files read as before): "<provider>/<account>", an account by its stable id — the login's, set once it is written and kept through renames (logins.json's savedLogin id, written by every write and stood in for by one made of the name until then, so an entry made before stands), a key by its fingerprint — every one a provider has when the list is set, and one gone later (a key rotated, an account signed out) kept as it is, matching nothing, holding the key closer, never wider. The command line and the menu name an account by who is signed in and keep its id. Routing holds a plan to the key's accounts beside its models: a candidate whose account the key may not use is left out — through a routing group the key names no less, for naming a group is not naming its accounts — the plan's order keeping step and its left-out list marking what the key held out (Weighed's held); magpie's own calls for the key — a web search, a picture described, a Codex title — are of the models the user picked, so the models don't hold them, but their spend lands on an account all the same, and the accounts hold them too. When every account or key a model has is one the key may not use, the request is refused with a 403 in the API's own error shape naming the model and the accounts the key may use, logged as a rejected call: after a usage cap's 429 and before an account barred for the model's, itself before the no-member 404. /v1/models and the Anthropic and Gemini lists show the key only the models an account or key it may use serves (a provider's account set not to serve one, #474, is none of the key's); a provider with no account and no key (a local ollama) is one the key names no account of — its models stay listed and its asks pass — while an entry kept after its provider lost its last account or key serves none, holding the key closer. The embeddings, images and videos endpoints hold their candidate to the key's accounts the same way, and counting tokens counts on those alone (the local estimate where it may use none). System One asks its decision model of an account or key the key may use — and sends on that key, of those in use, not the provider's first, which a key held to a later one was spent on; the videos and images keyed paths send on one the key may use too, held to a later key no longer refused for the first alone. Set it in the app's menu the models are picked in — the accounts after the models, an account by who is signed in with their plan in the note, a key by its fingerprint, what the CLI kept that no provider has now kept as "Not signed in now" — or magpie gateway-key accounts <id> codex/me@example.com openai/<key id> (all takes it off); gateway-key list has an ACCOUNTS column. en/zh/ja/de, the German "{n} accounts" main already had left to it rather than written twice. The images API's fan-out over a subscription's accounts is held to the key's accounts as one: one of the key's whose plan refuses to draw no longer hands the pen to an account it may not use, and the second in the order, when it is the key's, draws what the first may not (drawOnAccounts filters the candidates, the account pinned to with the account header told plainly when the key may not use it). The Routing view's left-out list says an account the key held out for what it is, not that its plan lacks the model, in Chinese, Japanese and German too; the key's badge names its accounts by who is signed in, not by the stable ids it keeps.

gateway: a Claude subscription conversation the client sends back rewritten goes on in the run that had its last turn, and Claude Code's temp images go with their session (#912, margbug01) — Alma takes the [Context: …] block out of its last user message once the turn is over, the <alma_notification> block out of the end of the reply, and picks the tools for each turn, so turnKey, which hashes all of it, never matched and every turn started a new claude -p told the whole conversation, written to the prompt cache again with its images. ended keeps a looseTurn beside the key: the settings without the tools, the conversation before the last turn hashed, and the last turn's messages one by one. When the exact key misses, rewritten takes the one idle run or saved session whose looseTurn has the same owner, settings and earlier turns, the same roles, tool calls and results in the last turn, where a user message only had one part taken out (cutFrom) and the reply is a non-empty start of what the run said. Two that could be it start a new run, as does an idle run not told a tool offered now (offers) or a saved session one of whose tools is gone (toolsCover). Claude Code's <CLAUDE_CODE_TMPDIR or /tmp>/claude-<uid>/<work project>/<session> folder, where it keeps the images it was given, is removed with the session (removeSession), and the sweep removes those a stopped gateway left once their session file is gone and nothing in them changed for a day; CLAUDE_CODE_TMPDIR joins agentenv.Vars. Old images are still sent to a new run: replacing them would change what the model sees. docs/subsystems/claude-subscription-bridge.md is new. claude_rewritten_test.go has a case for each relaxation (failing before the change) and one for each rule that keeps another conversation out (each failing with that rule taken out). Tested for real with the owner's Claude Max account in a sandbox HOME: turn one asked with a [Context] block and two tools, turn two sent it back with the block taken out, the reply cut short and one tool, and went on in the same claude process ("goes on in its run", cache_read 1932). go vet, go build (darwin, GOOS=linux nogui, GOOS=windows) and go test -tags nogui ./... under a temp HOME pass.

plugin, gui, docs: Plugins says which plugins are providers and which are middleware, lists the community's ready-made middleware, and edits a middleware's options in its row (the owner) — the Plugins page still read as if every plugin were a subscription, and nothing showed what a middleware does or let you set its options without editing plugins.json. Every Discover card and Installed row now carries a Provider or Middleware chip (both for a plugin that is both), also for one that is off (isMiddleware/middlewareOnly from the server, read from its files); Discover splits into Subscriptions and Gateway middleware ("runs in magpie's gateway on what every agent sends and gets back, whichever provider serves it"), the latter from market entries with "kind": "middleware" and no providers or icon (the built-in market.json lists the five new @magpie-community/middleware-* packages: param-override, model-map, system-prompt, word-guard, think-tags, mostly New API's channel settings with the same JSON). A middleware row has Options: a JSON editor in the row, starting from the package's magpie.options example when none are set, which validates it is an object, saves (POST /api/plugins/options) for the next request, clears, and cancels with Esc. magpie plugin options takes a short name (model-map for @magpie-community/middleware-model-map; plugin.ShortName, also in SetOptions). en/zh/ja/de. Docs: usemagpie.ai/docs/plugins (en/zh/ja) gains Ready-made middleware and Options and the registry's kind; reference.md, both READMEs and docs/subsystems/gateway-middleware.md likewise. Tested with a real DeepSeek account and real Claude Code through magpie web --gateway in a sandbox HOME, with all five installed and options set by short name: a mapped model named back, max_tokens capped, a prompt appended for claude only, word-guard's 400 and param-override's 403 in the agent's shape, <think> stripped from Chat and Responses streams and a whole Anthropic reply, reasoning_content moved into the text; /api/plugins showed the kinds and the example. TestSetOptionsShortName is new; TestBuiltinMarket checks a middleware entry has no providers or icon and no other kind. plugin-middleware.test.cjs (Chromium and WebKit, en and zh: the chips, Discover's two sections, the options editor with its errors, no select, no scroll, no left border) fails without the change; the other plugin tests and click-scroll pass in WebKit (plugin-market's section name updated; plugin-move fails only under parallel load and passes alone). go vet, go build (darwin, GOOS=linux nogui, GOOS=windows) and go test -tags nogui ./... under a temp HOME pass.

Subsystem design references

These pages describe current responsibilities, runtime paths, state, and contracts. Start with the subsystem relevant to your task, then follow its source links to verify the implementation you change.

Subsystem Reference
Built-in subscriptions moving to plugins Provider and plugin ownership
Plugins that run on the gateway's requests and replies Gateway middleware
Claude subscription turns across Claude Code runs Claude subscription bridge
How the gateway picks a provider, key or account, and falls back Gateway routing and fallback
Connecting an agent's config to the gateway, drift, disconnect, WSL twins Agent wiring
Providers, keys, subscription accounts, refresh and allowance Providers and accounts
Instructions, MCP servers, skills and RTK written into agents Library
Tray, panel, window, magpie web and the page's JSON API GUI app shell

A subsystem can span several packages or repositories. Its reference describes the behavior those parts provide together; it does not need to list every function.

Maintain a reference

Update the owning reference in the same PR when a change alters a documented responsibility, interface, state transition, runtime path, compatibility rule, or failure behavior. An internal refactor that preserves these contracts does not require a prose change.

Keep each fact in one reference and link to it from agent instructions or other pages. Link to source files and named symbols rather than copying implementation details that change frequently. Explain field meanings and constraints that signatures alone do not express.

For a new reference, include the responsibilities and boundaries, source of truth, main runtime paths, state transitions, important constraints, and existing verification commands. Include failure and compatibility behavior where relevant. Document current behavior separately from proposed changes; the proposal belongs in its issue or PR.

Describe a PR's semantic changes

For each affected subsystem, explain the observable change with its trigger and before/after behavior. Include changes to interfaces, state, compatibility, and failure behavior when relevant. Link the affected reference, implementation, and verification evidence. State when a refactor preserves the documented behavior.

For example, a change to plugin adoption should explain which migration state and account condition trigger it, which implementation handles requests before and after adoption, and which test exercises that transition.

This is an author-provided explanation that a reviewer verifies against the diff and surrounding code. It is not an automatically proven compatibility verdict.

Review a change

  1. Identify the affected subsystem and the actual runtime path, including plugin or built-in ownership.
  2. Compare the claimed before/after behavior with the base and head implementation. Trace relevant callers and state transitions beyond the changed lines.
  3. Check that changed contracts appear in the owning reference and that source links still resolve.
  4. Check that the cited tests or runtime evidence exercise the claimed behavior. Report checks that were not run.

A documentation update alone does not prove the implementation. Existing tests and runtime evidence remain necessary for behavior changes.
