chore: bump v0.2.43

feat(cmf): auto-detect tool support of managed local servers
cortiq serve >=0.5.62 advertises the loaded model's capabilities in /healthz ({"capabilities":{"tools":true}} when the chat template has a tools branch). The gateway now reads that handshake when the managed server becomes healthy and treats detected tool support as equivalent to declared caps in the candidate filter — so a low-tier chain made of a local model no longer widens agent (tools) traffic to cloud models once the local server can actually drive tools. Also adds an optional manual "caps" override to [[cmf.servers]] for older serve builds that do not advertise capabilities.

+## [0.2.43] - 2026-08-08
+
+### Added
+- **API keys actually gate the gateway.** Configured `[[api_keys]]` now enforce auth on
+  `/v1`, `/route` and `/mcp` (Bearer or `x-api-key`), attribute every request to the key's
+  account in stats, apply per-key rate limits (`rate_per_min` → 429 with `Retry-After`) and
+  per-key monthly budgets (`monthly_budget_usd` → 429 `insufficient_quota`). No keys
+  configured = open mode, as before.
+- **Auto-detected tool support for managed local servers**: `cortiq serve` ≥ 0.5.63
+  advertises the loaded model's capabilities in `/healthz`; the gateway reads the handshake
+  when the server becomes healthy, so a local model whose chat template can drive tool
+  calling serves agent (tools) traffic with zero manual configuration. Manual override:
+  `caps = ["tools"]` on the `[[cmf.servers]]` entry (also the fallback for older serves).
+- **OpenRouter balance on the dashboard** (when an OpenRouter key is configured): the
+  remaining credit is a KPI card, red under $5.
+- **Harness snippets for every OS** on the API-keys page: Linux/macOS and Windows variants
+  per harness, an install command chip when the harness is missing, and a paste-your-key
+  field that substitutes the real key into every snippet.
+- Deploy guide (`docs/DEPLOY.md`, Russian mirror): systemd/launchd/Windows service, nginx and
+  Caddy TLS fronting, security checklist, backup list.
+
+### Fixed
+- Capability filtering widens the tier chain instead of killing the request: when an AUTO
+  route's chain has no model with the required capabilities (tools), the gateway escalates
+  through medium→high chains and then the rest of the pool instead of returning
+  "No healthy model available". Explicit pins still fail loudly.
+- Semantic-cache threshold no longer renders as `0.9200000166893005` (f32→f64), the cache
+  settings card shows live entries/hits/saved-$ and warns when no embedding model exists.
+- Key-page snippets survive being pasted into a real interactive zsh (no `#` comment lines,
+  no history-expansion `!`), and the install chips are readable in the light theme.
+- Stats log growth is bounded: `[stats] max_file_mb` (default 16) folds old JSONL records
+  into the sidecar totals file — per-account all-time and month spend survive compaction
+  and restarts.
+
+### Breaking
+- If your config already lists `[[api_keys]]` but your clients never send keys, requests
+  will now be rejected with 401 — either remove the keys from the config or start sending
+  `Authorization: Bearer <key>`.
+
+## [0.2.42] - 2026-08-08
+
+### Added
+- **The continuous complexity score is visible**: the benchmark's routing table and the
+  dashboard's recent-requests list show the router's raw 0..1 score next to the tier badge —
+  see what different prompts actually weigh and tune the boundary sliders from real traffic.
+
+### Changed
+- Dashboard tier badges render translated tier names; the Russian locale calls the dashboard
+  «Рабочий стол».

+# Deploying cortiq-gateway for a team / office
+
+One gateway on a small server, API keys per department, local models for the
+cheap tiers, cloud models for the hard ones. This page covers the ops side.
+
+## 1. Run as a service
+
+### Linux (systemd)
+
+```ini
+# /etc/systemd/system/cortiq-gateway.service

+Description=Cortiq Gateway
+After=network-online.target
+
+[Service]
+User=cortiq

+ExecStart=/usr/local/bin/cortiq-gateway --no-port-search
+Restart=always
+RestartSec=3
+
+[Install]
+WantedBy=multi-user.target
+```
+
+```bash
+sudo systemctl enable --now cortiq-gateway
+```
+
+### macOS (launchd)
+
+```xml
+<!-- ~/Library/LaunchAgents/com.cortiq.gateway.plist -->
+<?xml version="1.0" encoding="UTF-8"?>
+<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
+<plist version="1.0"><dict>
+  <key>Label</key><string>com.cortiq.gateway</string>
+  <key>ProgramArguments</key><array>
+    <string>/usr/local/bin/cortiq-gateway</string>
+    <string>--no-port-search</string>
+  </array>
+  <key>RunAtLoad</key><true/>
+  <key>KeepAlive</key><true/>
+</dict></plist>
+```
+
+```bash
+launchctl load ~/Library/LaunchAgents/com.cortiq.gateway.plist
+```
+
+### Windows
+
+Task Scheduler → Create Task → "Run whether user is logged on or not",
+trigger At startup, action `cortiq-gateway.exe --no-port-search`. Or use
+[NSSM](https://nssm.cc): `nssm install cortiq-gateway C:\bin\cortiq-gateway.exe`.
+
+### Docker
+
+```bash
+docker run -d --restart unless-stopped -p 9000:9000 \
+  -v cortiq-data:/data ghcr.io/infosave2007/cortiq-gateway:latest
+```
+
+## 2. TLS and the outside world
+
+The gateway itself speaks plain HTTP — put a reverse proxy with TLS in front
+and bind the gateway to localhost:
+
+```toml
+# gateway.toml
+listen = "127.0.0.1:9000"
+```
+
+```nginx
+server {
+    listen 443 ssl;
+    server_name ai.example.com;
+    ssl_certificate     /etc/letsencrypt/live/ai.example.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/ai.example.com/privkey.pem;
+
+    location / {
+        proxy_pass http://127.0.0.1:9000;
+        proxy_http_version 1.1;
+        proxy_buffering off;          # SSE streaming
+        proxy_read_timeout 3600s;     # long generations
+    }
+}
+```
+
+(`caddy reverse-proxy --from ai.example.com --to 127.0.0.1:9000` does the
+same with automatic certificates.)
+
+## 3. Security checklist
+
+- **Admin token**: set `[admin] token` (or `CORTIQ_ADMIN_TOKEN`) — without it
+  the console warns that it is open to the network.
+- **API keys**: create one per department/developer on the keys page. With at
+  least one key configured the model APIs require Bearer / x-api-key —
+  requests without a valid key get 401.
+- **Rate limits**: per-key requests/min → 429 with Retry-After.
+- **Monthly budgets**: per-key $ ceiling → 429 insufficient_quota when the
+  account's month-to-date spend crosses it.
+- Bind to 127.0.0.1 behind the proxy; never expose the admin console raw.
+
+## 4. Backups
+
+Everything lives under the data directory (`CORTIQ_GATEWAY_HOME`):
+
+- `gateway.toml` — full config incl. keys (or use the console's TOML export);
+- `secrets.toml` — provider API keys (chmod 600);
+- `stats.jsonl` + `stats.jsonl.totals.json` — request accounting incl.
+  cumulative per-key totals and month-to-date budget spend.
+
+Copy those three and you can rebuild the instance anywhere.
+
+## 5. Observability
+
+- Dashboard: KPIs, per-key spend, recent requests with complexity scores,
+  OpenRouter balance (red under $5).
+- `GET /metrics` (enable `[telemetry] metrics = true`) for Prometheus.
+- Logs view in the console; `stats.max_file_mb` keeps the disk bounded.

+```
+
+## 2. TLS и внешний мир
+
+Сам шлюз говорит по HTTP — поставьте перед ним reverse-proxy с TLS, а шлюз
+привяжите к localhost:
+
+```toml
+# gateway.toml
+listen = "127.0.0.1:9000"
+```
+
+```nginx
+server {
+    listen 443 ssl;
+    server_name ai.example.com;
+    ssl_certificate     /etc/letsencrypt/live/ai.example.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/ai.example.com/privkey.pem;
+
+    location / {
+        proxy_pass http://127.0.0.1:9000;
+        proxy_http_version 1.1;
+        proxy_buffering off;          # SSE-стриминг
+        proxy_read_timeout 3600s;     # долгие генерации
+    }
+}
+```
+
+(`caddy reverse-proxy --from ai.example.com --to 127.0.0.1:9000` делает то же
+с автоматическими сертификатами.)
+
+## 3. Чек-лист безопасности
+
+- **Токен админки**: задайте `[admin] token` (или `CORTIQ_ADMIN_TOKEN`) — без
+  него консоль предупреждает, что открыта сети.
+- **API-ключи**: по ключу на отдел/разработчика на странице ключей. Как только
+  настроен хотя бы один ключ, модельные API требуют Bearer / x-api-key —
+  запросы без валидного ключа получают 401.
+- **Rate-limit**: запросов/мин на ключ → 429 с Retry-After.
+- **Месячные бюджеты**: потолок $ на ключ → 429 insufficient_quota, когда
+  траты аккаунта за месяц превысят лимит.
+- Привязывайте к 127.0.0.1 за прокси; не выставляйте админку наружу голой.
+
+## 4. Бэкапы
+
+Всё живёт в data-директории (`CORTIQ_GATEWAY_HOME`):
+
+- `gateway.toml` — полный конфиг вкл. ключи (или TOML-экспорт из консоли);
+- `secrets.toml` — ключи провайдеров (chmod 600);
+- `stats.jsonl` + `stats.jsonl.totals.json` — учёт запросов вкл. вечные
+  тоталы по ключам и месячные траты для бюджетов.
+
+Скопируйте эти три файла — и инстанс поднимается где угодно.
+
+## 5. Наблюдаемость
+
+- Рабочий стол: KPI, расходы по ключам, последние запросы с коэффициентами
+  сложности, баланс OpenRouter (красный ниже $5).
+- `GET /metrics` (включите `[telemetry] metrics = true`) для Prometheus.
+- Просмотр логов в консоли; `stats.max_file_mb` ограничивает диск.

infosave2007	19f666e7b1	feat(cmf): auto-detect tool support of managed local servers cortiq serve >=0.5.62 advertises the loaded model's capabilities in /healthz ({"capabilities":{"tools":true}} when the chat template has a tools branch). The gateway now reads that handshake when the managed server becomes healthy and treats detected tool support as equivalent to declared caps in the candidate filter — so a low-tier chain made of a local model no longer widens agent (tools) traffic to cloud models once the local server can actually drive tools. Also adds an optional manual "caps" override to [[cmf.servers]] for older serve builds that do not advertise capabilities.	2026-08-08 15:52:20 +03:00
infosave2007	dbcd9827f6	fix(pipeline): capability filtering widens the chain instead of killing the request OpenCode (like every coding agent) sends tool definitions with each request. The router rated the prompt low → the low-tier chain contained only the local model → the tools filter emptied the chain → hard failure: "No healthy model available that satisfies required capabilities", with the agent stuck in a retry loop. On an AUTO route whose filtered chain comes up empty, the pipeline now widens to any pool model satisfying the required capabilities — preferring the routing table's own medium→high order (an agentic request deserves a capable model), then the rest of the pool — and logs the widening. Pinned requests still fail loudly as before. Verified with OpenCode's exact request shape: cortiq-auto + tools at tier low now answers from deepseek in 1.2s instead of erroring.	2026-08-08 14:25:00 +03:00
infosave2007	b689180717	fix(keys): snippets survive being pasted into real zsh The copyable text opened with a "# hint" line — but default interactive zsh has interactivecomments off, so the line was parsed as a command, and the "!" inside «(перезапишет!)» fired history expansion: pasting the OpenCode snippet died with "zsh: event not found: )" before doing anything. Hints now live in the UI above the snippet; the clipboard gets commands only. Verified by piping the actual rendered snippet through an interactive zsh: the config file lands intact.	2026-08-08 14:16:22 +03:00
infosave2007	f385c2254b	fix(ui): install-command chip and bands slider readable in the light theme The chip used var(--panel-2, #23252c) — a variable that doesn't exist with a hard dark fallback, so in the light theme the install command was a dark box with dark text. Same class of bug in the bands slider track and handle labels (invented --panel-2/--fg vars). All moved to the real theme variables (--panel/--border/--text) via a .cmd-chip class; verified by computed styles in the light theme (text rgb(15,23,42) on white) and screenshots of both views.	2026-08-08 14:12:39 +03:00
infosave2007	9607a38792	feat(keys): paste-your-key field — snippets carry the real key instantly Next to the copy button: a key input and an «Insert key» button (Enter works too). The pasted key substitutes into every harness/SDK snippet immediately and survives tab and OS switches; a freshly created key pre-fills the field. No more copying a snippet and then hand-editing the placeholder. 2 strings ×7 languages.	2026-08-08 14:07:11 +03:00
infosave2007	239ddc767c	feat(keys): harness snippets for every OS + install command when missing The harness auto-setup scripts were bash-only (heredocs, mkdir -p) — useless on Windows. Every scripty snippet now exists in two flavors behind a 🐧🍎/🪟 switch (auto-detected from the browser): bash heredocs for Linux/macOS and PowerShell here-strings ($env:, New-Item, @'..'@, curl.exe with backtick continuations) for Windows. SDK snippets and GUI instructions stay OS-independent. And when detection says a harness is NOT installed on the gateway machine, the status line now offers its one-line install command for the selected OS (claude.ai install.sh / install.ps1, npm -g for Codex and OpenCode-on- Windows, code --install-extension for Continue/Cline) with a copy button. 1 string ×7 languages.	2026-08-08 14:05:47 +03:00
infosave2007	057abaa95a	feat!: API keys actually gate the gateway — auth, attribution, rate limits, budgets The office-readiness audit found the foundation missing: configured API keys were decorative. Any bearer — or none — passed every model endpoint, per-key rate limits existed only in the form, and all real traffic was recorded as "anonymous", leaving the per-key spend table permanently blank. A middleware on the model surface (/v1/*, /route, /mcp) now enforces keys: - no keys configured → open mode as before (the console already warns); - keys exist → Bearer or x-api-key must match (401 invalid_api_key); - per-key rate_per_min → fixed one-minute window, 429 with Retry-After; - NEW per-key monthly_budget_usd → 429 insufficient_quota once the account's month-to-date spend crosses the ceiling; - the matched account rides the request into stats — the keys table's spend columns finally see real traffic. Month-to-date spend is tracked per account in stats and persisted in the totals sidecar with a watermark (no double counting across restarts). The key dialog gains a budget field; the table shows "budget $N/mo" in red once exhausted. All verified live: 401 wrong/missing key, 200 + attribution with the right key, 429 + Retry-After over the limit, 429 insufficient_quota on the second request past a $0.000001 budget. Also: the dashboard shows the OpenRouter credit balance (GET /api/v1/credits via the stored key, cached 5 min, hidden without a key, red under $5 — live: $16.18), the server drains connections on Ctrl-C instead of dropping them, request bodies are capped at 32 MB, and docs/DEPLOY(.ru) cover office deployment: systemd/launchd/Windows service, nginx/caddy TLS, security checklist, backups. 10 strings ×7 languages.	2026-08-08 14:01:16 +03:00
infosave2007	dd864eed22	fix(cache): honest settings card — clean threshold, live stats, no-embedder warning Full audit of the semantic cache against a live instance (mock embedder, identical requests): the mechanism works — miss at 3.1s, then hits at 2ms with entries/hits/saved-$ counting. Two honest gaps fixed: - the threshold round-tripped through f32 and rendered as 0.9200000166893005 in both the TOML and the settings input — the config field is f64 now (writes exactly what you typed) and the input rounds legacy values to 2 decimals; - the card now shows proof of life (entries / hits / hit-rate / saved $) and, when the cache is enabled with NO embedding model available, a warning that it is silently doing nothing and how to fix it — previously that state looked identical to a working cache. Also audited in the same pass, no changes needed: Prometheus /metrics (toggle on/off applies live, 404 when off), and all 7 protocol switches (each gates its endpoint instantly both ways). 4 strings ×7 languages.	2026-08-08 13:21:43 +03:00

infosave2007	9ef1af3ae1	feat(ui): the continuous complexity score shows next to the tier Benchmark (routing mode) and the dashboard's recent-requests list now print the router's raw 0..1 score under/next to the tier badge — people can see what different prompts actually weigh and tune the boundary sliders from real data. Tooltip explains the link to the Routing sliders (7 languages). Caught before commit: naming the field row.score collided with the answer- correctness fraction from evaluate() and dragged the benchmark's quality KPI down to the average complexity — renamed to cscore, KPI verified back at 100%. Dashboard tier badges also render translated names now, and the Russian locale calls the dashboard «Рабочий стол».	2026-08-08 12:11:07 +03:00
