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».
+
+## [0.2.41] - 2026-08-08
+
+### Added
+- **Linked complexity-boundary sliders** on the Routing page: one track, two draggable handles
+  (the low|medium and medium|high boundaries) over green/amber/red zones. Handles push each
+  other, the numbers ride on the handles and the legend updates live — no hand-typed score
+  ranges. The gateway re-maps the router's continuous complexity score with YOUR boundaries
+  (`[routing.bands]`, validated `0 < low < medium < 1`) before tier chains, escalation and
+  stats; unchecked = the router's own bands, untouched behavior.
+
+### Fixed
+- Complexity tier names are translated everywhere they appear (bands legend, tier badges, pair
+  selects, benchmark column, Playground decision): лёгкий/средний/сложный, leicht/mittel/schwer,
+  facile/moyen/difficile, fácil/medio/difícil, 简单/中等/困难, kolay/orta/zor.
+- Benchmark route-judged retries re-ask the SAME prompt after a pause before reaching for a
+  fresh template — difficulty is judged in the background, so the second occurrence is the
+  honest steady-state answer.
+
+## [0.2.40] - 2026-08-08
+
+### Added
+- **Per-key spend accounting** on the API-keys page: requests, tokens in/out and cost per key
+  for a selectable window (24h / 7d / 30d) plus a cumulative all-time cost column — "which
+  department spends what" at a glance.
+- **Bounded stats on disk**: once `stats.jsonl` outgrows `stats.max_file_mb` (default 16, 0
+  disables), records older than the retention window fold into cumulative per-account totals in
+  a small sidecar file (tmp+rename on both) and leave the log. All-time accounting survives
+  compaction and restarts; nothing is ever counted twice.
+- **Per-complexity models inside a task rule**: each task is edited as rows of
+  "model + complexity" pairs — `[routing.tasks.code] low=["cheap"] high=["best"] any=[...]`.
+  The tier-specific pick leads its own tier, `any` (and legacy plain arrays) leads everywhere,
+  the global tier chain and `default` always remain as fallback, and high verdicts still
+  escalate over any-tier pins.
+
+### Changed
+- Benchmark hard probes are generated from wider interdisciplinary pools (6 families each) and
+  retry once with a fresh template — the router's novelty decay no longer flips them red.
+
+### Fixed
+- The `task-rule` badge is honest: it appears only when the rule actually chose the head of the
+  candidate chain, not whenever a rule merely exists for the task.

+sudo systemctl enable --now cortiq-gateway
+```
+
+### macOS (launchd)

+```
+
+```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`.

+```bash

+  -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

+    listen 443 ssl;

+        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

infosave2007	0040bfd7e9	fix(routing): the high zone is unmistakably red At 35% opacity over the dark background the amber medium zone and the light-red high zone read as the same color right of the medium handle. Saturation stepped up per zone (45/55/65%) and high uses a deeper red — green / amber / red now read at a glance.	2026-08-08 09:53:25 +03:00
infosave2007	10b5101757	fix(i18n): complexity tier names are translated everywhere they're shown low/medium/high leaked as raw English into the bands legend, the tier badges on the Routing page, the pair complexity selects, the benchmark's tier column and the Playground decision panel. New trTier() helper renders the human name (ru: лёгкий/средний/сложный, de: leicht/mittel/schwer, fr/es/zh/tr likewise); custom tier names pass through untouched, badge colors stay keyed by the raw tier. Verified in the browser in Russian and German.	2026-08-08 09:51:38 +03:00
infosave2007	788c87c565	feat(routing): linked complexity-boundary sliders — your own low/medium/high The tier boundaries lived on the router and were global for every customer of a hosted router; per-gateway tuning meant hand-editing score ranges. The Routing page now has one track with two draggable handles (the low\|medium and medium\|high boundaries) over three colored zones: handles push each other (low can't cross medium — it shoves it along, and vice versa), the numbers ride on the handles and the legend updates live, so nobody types ranges by hand. Unchecked = the router's own bands, untouched behavior. Under the hood the gateway re-maps the router's CONTINUOUS complexity score with the user's boundaries ([routing.bands] low/medium in gateway.toml, validated 0 < low < medium < 1) before tier chains, escalation and stats — verified live: with bands at 0.70/0.72 a score-0.27 request that used to be medium routed low, and back after restoring the defaults. 2 new strings in all 7 languages.	2026-08-08 09:48:36 +03:00
infosave2007	179c414a0e	fix(benchmark): retry the SAME hard prompt after a pause before reaching for a fresh one Difficulty is judged in the background: the first-ever occurrence of a hard prompt routes by prior (often low/medium), the oracle's judgement lands in the cache a couple of seconds later. The route-judged retry fired instantly with a FRESH template — which has the same first-encounter fate — so the test could go red exactly when the system was working as designed. The retry now re-asks the same prompt after 4s (steady-state answer from the cache), and only then tries a fresh template.	2026-08-08 09:23:53 +03:00

infosave2007	b24d4cdbab	fix(routing): the task-rule badge only when the rule actually chose the head route_source reported "+task-rule" whenever a rule existed for the task — so a math prompt routed low by the ordinary tier chain still wore the badge next to the local model, reading as "the rule picked this" when it hadn't (the rule only defines math@high). matched now means the head of the chain came from the rule's tier-specific or any-tier list; verified live: the same low math request now reports route_source "router".	2026-08-08 09:02:25 +03:00
infosave2007	06813b3e97	feat(routing)!: task rules become per-complexity model maps The single per-task «Complexity» pin was the wrong shape — what you actually decide is WHICH model serves a task at WHICH complexity. A task rule is now a per-tier map, edited in the console as rows of “model ▾ + complexity ▾” pairs (plus ×/add) inside each task: [routing.tasks.code] low = ["cheap-coder"] high = ["best-coder"] any = ["generic-coder"] # leads at every tier after the tier pick Chain order: the task's tier-specific list → (at high: the global high chain, so escalation still beats any-tier pins) → the task's any-tier list → the global tier chain → default as the last resort; deduplicated. Plain-array rules keep meaning "any tier" unchanged, and the short-lived {models, tier} form from the previous commit is normalized into the map on load. Verified live: legacy config migrated visibly in the editor, pairs survive save+reload, a math prompt at low ignored the math@high pair, per-tier leads confirmed by unit tests (19 passing).	2026-08-08 08:54:27 +03:00
infosave2007	95e560dc72	feat: per-key spend accounting and per-task complexity pinning API keys page: the table now answers "which department spends what" — per-key requests, tokens in/out and cost for a selectable window (24h/7d/30d) plus a cumulative all-time cost column, joined from stats by the key's account. The stats log stays bounded while the accounting survives: once stats.jsonl exceeds max_file_mb (default 16, 0 disables), records older than the retention window fold into cumulative per-account totals in a small sidecar file (tmp+rename on both) and leave the log. alltime = folded + in-file, a record is never counted twice, verified end-to-end on synthetic data (1.2 MB → 301 KB, totals identical before/after compaction and restarts). Routing: a task rule can now PIN the complexity tier — `[routing.tasks.legal] models=[...] tier="high"` (old plain-array rules parse unchanged). The pinned tier replaces the router's verdict before the escalation check and reports itself as route_source "router+task-rule@high". The Routing page grows a per-task «Complexity» selector (Auto/low/medium/ high); verified live: a code prompt with a pinned high went router+task-rule@high → the expensive model. 13 new strings in all 7 languages; docs/ROUTING(.ru) updated.	2026-08-08 08:42:11 +03:00
infosave2007	ef28a6633d	fix(benchmark): hard probes survive their own popularity The router deliberately scores familiar text as less novel, so every benchmark run slightly burns the hard-prompt pool — with 3 templates per test a variant would drift below the high band within a handful of runs and flip the test red for no real reason. Two-part fix: pools doubled to 6 interdisciplinary families each (science: + quantum error correction, soil-carbon MRV, cryo-EM; ops: + ED triage + staffing, port berth/tides/rail, agri-drone fleets — all probed high against the live router), and a route-judged test that lands non-high gets ONE retry with a freshly generated template before failing. A single burnt wording no longer fails the assertion; a genuinely unreachable high tier still does.	2026-08-07 22:47:28 +03:00
