gateway: each gateway key can have its own limit, a token total and/or an estimated cost per day, week or month, and a spent key is refused before any provider is asked (margbug01 on #585, v0.1.671: 每个网关密钥都能设置自己的用量上限) — a gateway key named who called and the Usage page grouped its calls, but nothing held a key to an amount, so one client shared on the network could spend a subscription's whole window. A key now carries limit {period day|week|month, tokens, cost, cacheReads} in caller-keys.json, set with the new "limit-key" change. Windows are calendar ones in local time (from midnight, from Monday, from the 1st) and a call counts in the window it started in. Tokens are a call's uncached input, output and cache writes, plus cache reads when the limit says so; cost is an estimate at the Usage page's effective prices (usage.NewCoster), a call with no known price adding none and counted as unpriced. What a key used is summed from usage.jsonl (usage.Visit), so it survives a restart; the new internal/budget keeps the sums in memory per window and appendUsage writes a key's record through budget.Append, which appends and counts under one lock so a window read meanwhile never counts a call twice. Before a keyed POST reaches the mux, keyLimited reserves for it: its body's size in tokens (4 bytes a token) plus the key's mean output per call this window, at the window's cost per token or the named model's input price; it is let in while used + reserved is under the cap, so requests sent at once overshoot by about one call, and the reservation is released when the request ends, a streamed reply being settled then with the usage its vendor reported. A spent key gets a 429 in its API's error shape (Anthropic, OpenAI chat/responses, Gemini) naming the key, the cap and the reset time, with Retry-After, X-Should-Retry: false and X-Magpie-Limit-Reset, recorded as a rejected call (gateway_key_limit); other keys go on. Requests from this computer without a gateway key are not limited; a key used from this computer is. count_tokens and bridge callbacks are never held. GET /v1/magpie/limit tells a key its own status. Gateway keys rows show a Limit badge (what is used of it, per what, Spent in red) and a line under a limited key (used of limit, left, resets / refused until, in flight; unpriced calls in its title); Limit opens an editor under the row (window, tokens with k/m/万/亿, cost in US$, Count cache reads too, what is counted) staged until Save, marked unsaved, Cancel/Escape dropping it, a bad amount disabling Save, No limit removing it; en and zh; no left-border accent; no click scrolls. The CLI gains magpie gateway-key limit <id> [off | day|week|month --tokens N --cost USD --cache-reads] and a LIMIT column in list. TestKeyLimitRefusesBeforeUpstream (two calls within 700 tokens, the third a 429 the fake upstream never sees, message/type/headers, the rejected record, Anthropic's shape on /v1/messages, another key and a keyless loopback request let in, still refused after budget.Forget as after a restart, a raised and a removed limit let in, /v1/magpie/limit), TestKeyLimitHoldsParallelRequests (20 at once against 2000 tokens: some refused, at most one call over, no reservation left; without the reservation all 20 got in and 7350 were used), TestKeyLimitWindowResets, TestLimitWindow, TestLimitValid and TestGatewayKeyLimitCLI are new; gateway-key-limit.test.cjs (WebKit, en and zh) is new and passes, as do gateway-caller-keys, gateway-connect-keys, api-key-theme and click-scroll (whose request-pick case flaked once under a parallel run and passes alone, as on main). go vet ./internal/..., go build -tags nogui (darwin, GOOS=linux), GOOS=windows go build, go test -tags nogui -count=1 ./... under a temp HOME pass (TestFXInState's known TempDir-cleanup flake aside).
