 ### ✨ New Features
 
@@ -24,6 +22,11 @@ _In development — bullets added per PR; finalized at release._
 - **feat(cc): per-connection "summarized thinking display" toggle for Claude-Code-compatible providers** — exposes a connection-level toggle that drives the existing Copilot summarized-thinking marker, so operators can opt a CC-compatible connection into summarized reasoning display from the UI (schema + request defaults + provider modals, with i18n). (thanks @rdself)
 - **feat(compression): compression playground in the studio (Play + Compare tabs)** — `/dashboard/compression/studio` gains a synthetic playground: paste text → per-engine **lanes** (each deterministic engine run alone via `/api/compression/preview`) plus a **combined waterfall** ordered by `stackPriority`, and a free **A/B Compare** grid with on-demand, **USD-capped** fidelity verdicts (`/api/compression/compare` + `compare/verify`). The preview route now uses the real cl100k tokenizer, returns `engineBreakdown`, and accepts an ordered `pipeline[]`; new `compare` / `compare/verify` / `retrieve` routes; the live WS feed moved to `/dashboard/compression/live`. Management-only. ([#5080](https://github.com/diegosouzapw/OmniRoute/pull/5080))
 - **feat(dashboard): expose Fusion `judgeModel` + `fusionTuning` in the combo editor** — the Fusion strategy editor now surfaces the judge model (synthesizes the panel answers; defaults to the first panel model) plus the quorum-grace tuning fields (`minPanel`, `stragglerGraceMs`, `panelHardTimeoutMs`) that `open-sse/services/fusion.ts` already reads. Schema-validated + bounded; empty tuning is never persisted. ([#5074](https://github.com/diegosouzapw/OmniRoute/pull/5074))
+- **feat(compression): opt-in per-step fidelity gate for the stacked pipeline** — each compression step can now be guarded by a pure fidelity checker (4 invariants, fail-open) so a lossy engine that would degrade the prompt past a threshold is rejected and its lane skipped instead of silently shipping. Configurable via `fidelityGate` (advanced thresholds intentionally API-omitted), with a per-lane rejection breakdown surfaced in the studio playground toggle. ([#5143](https://github.com/diegosouzapw/OmniRoute/pull/5143))
+- **feat(compression): fuzzy near-duplicate dedup (session-dedup 2nd pass)** — the session-dedup engine gains a second fuzzy pass that collapses near-duplicate (not just byte-identical) segments, with a playground toggle to compare on/off. ([#5143](https://github.com/diegosouzapw/OmniRoute/pull/5143))
+- **feat(quota): opt-in Codex/Claude auto-ping keepalive** — an opt-in background keepalive can periodically ping Codex/Claude connections to keep their session/quota state warm, reducing cold-start failures on the first real request. ([#5102](https://github.com/diegosouzapw/OmniRoute/pull/5102))
+- **feat(ops): SRE playbooks + ops helper scripts** — salvaged from a closed stale PR; adds operator runbooks and ops helper scripts. ([#5138](https://github.com/diegosouzapw/OmniRoute/pull/5138) — thanks @KooshaPari / @diegosouzapw)
+- **feat(mcp): web-session robustness — cookie dedup + browser-pool observability** — the MCP web-session path now de-duplicates cookies when (re)hydrating a session (avoiding conflicting duplicate `Cookie` headers) and exposes browser-pool observability (pool size / in-use / acquisition metrics) for the headless web providers. ([#5121](https://github.com/diegosouzapw/OmniRoute/pull/5121), builds on [#3368](https://github.com/diegosouzapw/OmniRoute/issues/3368))
 
 ### 🔧 Bug Fixes
 
@@ -53,14 +56,32 @@ _In development — bullets added per PR; finalized at release._
 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on). The redundant cleanup is removed (per-model removal already handles its own compat cleanup), so eye-hidden models stay hidden across re-sync. (#4389, thanks @herjarsa)

([#5086](https://github.com/diegosouzapw/OmniRoute/pull/5086) — thanks @herjarsa)
 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format). (thanks @StevanusPangau)
-- **fix(translator): stop stripping client-provided `reasoning_content` for reasoning-replay providers** — the #4849 agentic-context strip (which drops `reasoning_content` from tool-call assistant turns to avoid O(n²) token growth) ran unconditionally, so replay providers (DeepSeek V4, Kimi K2, Qwen-Thinking, etc.) lost the client's reasoning and the reasoning-replay cache then overwrote it with a stale cached value (and such upstreams 400 without the original reasoning). The strip now skips reasoning-replay targets while non-reasoning providers keep the O(n²) protection.

The strip now skips reasoning-replay targets while non-reasoning providers keep the O(n²) protection. ([#5122](https://github.com/diegosouzapw/OmniRoute/pull/5122))
+- **fix(providers): add MiniMax M3 & Nemotron 3 Ultra to the Cline catalog** — the two models were missing from Cline's provider catalog and could not be selected; both are now registered. ([#5136](https://github.com/diegosouzapw/OmniRoute/pull/5136), closes [#3321](https://github.com/diegosouzapw/OmniRoute/issues/3321))
+- **fix(dashboard): key model-visibility toggle on the canonical `providerId`** — the per-model visibility toggle keyed off a display id, so toggling a model on one provider alias could mis-target another; it now keys on the canonical `providerId`. ([#5091](https://github.com/diegosouzapw/OmniRoute/pull/5091) — thanks @Theadd)
+- **fix(diagnostics): recognize the Claude API format in `detectMalformedNonStream`** — salvaged null-guard so a Claude-shaped non-streaming body is no longer misclassified. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @herjarsa / @diegosouzapw)
+- **fix(logging): track the final connection IDs in failover logs** — failover log lines now record the connection that actually served (or last failed) the request, instead of only the first attempt. ([#5016](https://github.com/diegosouzapw/OmniRoute/pull/5016) — thanks @JxnLexn)
+- **fix(sse): ignore disconnect races during in-band stream error handling** — a client disconnect that races with in-band upstream error handling no longer surfaces as a spurious provider failure. ([#5007](https://github.com/diegosouzapw/OmniRoute/pull/5007) — thanks @JxnLexn)
+- **fix(dashboard): surface the server error on `handleToggleCombo` failure** — a failed combo toggle now shows the backend error instead of silently no-op'ing. ([#5138](https://github.com/diegosouzapw/OmniRoute/pull/5138) — thanks @KooshaPari / @diegosouzapw)
+- **fix(quota): track provider quota reset windows + enrich the Codex playground** — observed quota reset windows are tracked and surfaced, and the Codex playground gains the enriched quota metadata. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @Witroch4 / @diegosouzapw)
+- **fix(sidebar): drop the orphan `settings` accent color** — removed a dangling accent-color entry that broke `typecheck:core`. ([#5142](https://github.com/diegosouzapw/OmniRoute/pull/5142))
+
+### 🔒 Security
+
+- **fix(security): exact-host Anthropic `baseUrl` check** — the Anthropic base-URL guard used a substring match that a crafted host could partially satisfy; it now requires an exact host match (resolves CodeQL `js/incomplete-url-substring-sanitization` alert #674). ([#5130](https://github.com/diegosouzapw/OmniRoute/pull/5130))
+
+### 📝 Maintenance
+
+- **refactor(store): remove dead legacy store modules** — salvaged cleanup of unused legacy store code. ([#5138](https://github.com/diegosouzapw/OmniRoute/pull/5138) — thanks @JxnLexn / @diegosouzapw)
+- **test(combo): deterministic routing-decision matrix for all 17 strategies** — a deterministic E2E matrix pins the routing decision of every combo strategy. ([#5146](https://github.com/diegosouzapw/OmniRoute/pull/5146))
+- **chore:** baseline reconciliations (complexity / file-size / cognitive), golden-snapshot + apikey-count alignment for new providers, orphan-test relocation, release base-red repairs, CHANGELOG i18n mirror sync, and an `actions/cache` 5→6 bump. ([#5145](https://github.com/diegosouzapw/OmniRoute/pull/5145), [#5144](https://github.com/diegosouzapw/OmniRoute/pull/5144), [#5125](https://github.com/diegosouzapw/OmniRoute/pull/5125), [#5126](https://github.com/diegosouzapw/OmniRoute/pull/5126), [#5120](https://github.com/diegosouzapw/OmniRoute/pull/5120), [#5117](https://github.com/diegosouzapw/OmniRoute/pull/5117), [#5112](https://github.com/diegosouzapw/OmniRoute/pull/5112))

 - **fix(security):** do not trust the loopback socket as local-only when the server is behind a reverse proxy, closing a potential auth bypass path. ([#4632](https://github.com/diegosouzapw/OmniRoute/pull/4632))
 - **fix(security):** validate the Kiro region parameter to prevent SSRF via crafted region strings (GHSA-6mwv-4mrm-5p3m). ([#4629](https://github.com/diegosouzapw/OmniRoute/pull/4629))
 - **fix(copilot):** replace `execSync` shell interpolation with `execFile` in the `runOmniRouteCli` tool to prevent command injection. The user-supplied command is now split into an argv array and passed to `execFile` (no shell), so shell metacharacters are treated as literal text; error output is routed through `sanitizeErrorMessage()`. ([#5024](https://github.com/diegosouzapw/OmniRoute/pull/5024) — thanks @hamsa0x7)

 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on). The redundant cleanup is removed (per-model removal already handles its own compat cleanup), so eye-hidden models stay hidden across re-sync. (#4389, thanks @herjarsa)

([#5086](https://github.com/diegosouzapw/OmniRoute/pull/5086) — thanks @herjarsa)
 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format). (thanks @StevanusPangau)
-- **fix(translator): stop stripping client-provided `reasoning_content` for reasoning-replay providers** — the #4849 agentic-context strip (which drops `reasoning_content` from tool-call assistant turns to avoid O(n²) token growth) ran unconditionally, so replay providers (DeepSeek V4, Kimi K2, Qwen-Thinking, etc.) lost the client's reasoning and the reasoning-replay cache then overwrote it with a stale cached value (and such upstreams 400 without the original reasoning). The strip now skips reasoning-replay targets while non-reasoning providers keep the O(n²) protection.

+- **fix(providers): add MiniMax M3 & Nemotron 3 Ultra to the Cline catalog** — the two models were missing from Cline's provider catalog and could not be selected; both are now registered. ([#5136](https://github.com/diegosouzapw/OmniRoute/pull/5136), closes [#3321](https://github.com/diegosouzapw/OmniRoute/issues/3321))
+- **fix(dashboard): key model-visibility toggle on the canonical `providerId`** — the per-model visibility toggle keyed off a display id, so toggling a model on one provider alias could mis-target another; it now keys on the canonical `providerId`. ([#5091](https://github.com/diegosouzapw/OmniRoute/pull/5091) — thanks @Theadd)
+- **fix(diagnostics): recognize the Claude API format in `detectMalformedNonStream`** — salvaged null-guard so a Claude-shaped non-streaming body is no longer misclassified. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @herjarsa / @diegosouzapw)
+- **fix(logging): track the final connection IDs in failover logs** — failover log lines now record the connection that actually served (or last failed) the request, instead of only the first attempt. ([#5016](https://github.com/diegosouzapw/OmniRoute/pull/5016) — thanks @JxnLexn)
+- **fix(sse): ignore disconnect races during in-band stream error handling** — a client disconnect that races with in-band upstream error handling no longer surfaces as a spurious provider failure. ([#5007](https://github.com/diegosouzapw/OmniRoute/pull/5007) — thanks @JxnLexn)
+- **fix(dashboard): surface the server error on `handleToggleCombo` failure** — a failed combo toggle now shows the backend error instead of silently no-op'ing. ([#5138](https://github.com/diegosouzapw/OmniRoute/pull/5138) — thanks @KooshaPari / @diegosouzapw)
+- **fix(quota): track provider quota reset windows + enrich the Codex playground** — observed quota reset windows are tracked and surfaced, and the Codex playground gains the enriched quota metadata. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @Witroch4 / @diegosouzapw)
+- **fix(sidebar): drop the orphan `settings` accent color** — removed a dangling accent-color entry that broke `typecheck:core`. ([#5142](https://github.com/diegosouzapw/OmniRoute/pull/5142))
+
+### 🔒 Security
+
+- **fix(security): exact-host Anthropic `baseUrl` check** — the Anthropic base-URL guard used a substring match that a crafted host could partially satisfy; it now requires an exact host match (resolves CodeQL `js/incomplete-url-substring-sanitization` alert #674). ([#5130](https://github.com/diegosouzapw/OmniRoute/pull/5130))
+
+### 📝 Maintenance
+
+- **refactor(store): remove dead legacy store modules** — salvaged cleanup of unused legacy store code. ([#5138](https://github.com/diegosouzapw/OmniRoute/pull/5138) — thanks @JxnLexn / @diegosouzapw)
+- **test(combo): deterministic routing-decision matrix for all 17 strategies** — a deterministic E2E matrix pins the routing decision of every combo strategy. ([#5146](https://github.com/diegosouzapw/OmniRoute/pull/5146))
+- **chore:** baseline reconciliations (complexity / file-size / cognitive), golden-snapshot + apikey-count alignment for new providers, orphan-test relocation, release base-red repairs, CHANGELOG i18n mirror sync, and an `actions/cache` 5→6 bump.

 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on). The redundant cleanup is removed (per-model removal already handles its own compat cleanup), so eye-hidden models stay hidden across re-sync. (#4389, thanks @herjarsa)

([#5086](https://github.com/diegosouzapw/OmniRoute/pull/5086) — thanks @herjarsa)
 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format). (thanks @StevanusPangau)
-- **fix(translator): stop stripping client-provided `reasoning_content` for reasoning-replay providers** — the #4849 agentic-context strip (which drops `reasoning_content` from tool-call assistant turns to avoid O(n²) token growth) ran unconditionally, so replay providers (DeepSeek V4, Kimi K2, Qwen-Thinking, etc.) lost the client's reasoning and the reasoning-replay cache then overwrote it with a stale cached value (and such upstreams 400 without the original reasoning).

 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on). The redundant cleanup is removed (per-model removal already handles its own compat cleanup), so eye-hidden models stay hidden across re-sync. (#4389, thanks @herjarsa)

([#5086](https://github.com/diegosouzapw/OmniRoute/pull/5086) — thanks @herjarsa)
 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format). (thanks @StevanusPangau)
-- **fix(translator): stop stripping client-provided `reasoning_content` for reasoning-replay providers** — the #4849 agentic-context strip (which drops `reasoning_content` from tool-call assistant turns to avoid O(n²) token growth) ran unconditionally, so replay providers (DeepSeek V4, Kimi K2, Qwen-Thinking, etc.) lost the client's reasoning and the reasoning-replay cache then overwrote it with a stale cached value (and such upstreams 400 without the original reasoning). The strip now skips reasoning-replay targets while non-reasoning providers keep the O(n²) protection.

+- **fix(dashboard): key model-visibility toggle on the canonical `providerId`** — the per-model visibility toggle keyed off a display id, so toggling a model on one provider alias could mis-target another; it now keys on the canonical `providerId`.

(thanks @rdself)

 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on). The redundant cleanup is removed (per-model removal already handles its own compat cleanup), so eye-hidden models stay hidden across re-sync. (#4389, thanks @herjarsa)

([#5086](https://github.com/diegosouzapw/OmniRoute/pull/5086) — thanks @herjarsa)
 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format). (thanks @StevanusPangau)
-- **fix(translator): stop stripping client-provided `reasoning_content` for reasoning-replay providers** — the #4849 agentic-context strip (which drops `reasoning_content` from tool-call assistant turns to avoid O(n²) token growth) ran unconditionally, so replay providers (DeepSeek V4, Kimi K2, Qwen-Thinking, etc.) lost the client's reasoning and the reasoning-replay cache then overwrote it with a stale cached value (and such upstreams 400 without the original reasoning). The strip now skips reasoning-replay targets while non-reasoning providers keep the O(n²) protection.

+- **fix(providers): add MiniMax M3 & Nemotron 3 Ultra to the Cline catalog** — the two models were missing from Cline's provider catalog and could not be selected; both are now registered. ([#5136](https://github.com/diegosouzapw/OmniRoute/pull/5136), closes [#3321](https://github.com/diegosouzapw/OmniRoute/issues/3321))
+- **fix(dashboard): key model-visibility toggle on the canonical `providerId`** — the per-model visibility toggle keyed off a display id, so toggling a model on one provider alias could mis-target another; it now keys on the canonical `providerId`. ([#5091](https://github.com/diegosouzapw/OmniRoute/pull/5091) — thanks @Theadd)
+- **fix(diagnostics): recognize the Claude API format in `detectMalformedNonStream`** — salvaged null-guard so a Claude-shaped non-streaming body is no longer misclassified. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @herjarsa / @diegosouzapw)
+- **fix(logging): track the final connection IDs in failover logs** — failover log lines now record the connection that actually served (or last failed) the request, instead of only the first attempt. ([#5016](https://github.com/diegosouzapw/OmniRoute/pull/5016) — thanks @JxnLexn)
+- **fix(sse): ignore disconnect races during in-band stream error handling** — a client disconnect that races with in-band upstream error handling no longer surfaces as a spurious provider failure. ([#5007](https://github.com/diegosouzapw/OmniRoute/pull/5007) — thanks @JxnLexn)
+- **fix(dashboard): surface the server error on `handleToggleCombo` failure** — a failed combo toggle now shows the backend error instead of silently no-op'ing. ([#5138](https://github.com/diegosouzapw/OmniRoute/pull/5138) — thanks @KooshaPari / @diegosouzapw)
+- **fix(quota): track provider quota reset windows + enrich the Codex playground** — observed quota reset windows are tracked and surfaced, and the Codex playground gains the enriched quota metadata. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @Witroch4 / @diegosouzapw)
+- **fix(sidebar): drop the orphan `settings` accent color** — removed a dangling accent-color entry that broke `typecheck:core`. ([#5142](https://github.com/diegosouzapw/OmniRoute/pull/5142))
+
+### 🔒 Security
+
+- **fix(security): exact-host Anthropic `baseUrl` check** — the Anthropic base-URL guard used a substring match that a crafted host could partially satisfy; it now requires an exact host match (resolves CodeQL `js/incomplete-url-substring-sanitization` alert #674).

 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on). The redundant cleanup is removed (per-model removal already handles its own compat cleanup), so eye-hidden models stay hidden across re-sync. (#4389, thanks @herjarsa)

([#5086](https://github.com/diegosouzapw/OmniRoute/pull/5086) — thanks @herjarsa)
 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format). (thanks @StevanusPangau)
-- **fix(translator): stop stripping client-provided `reasoning_content` for reasoning-replay providers** — the #4849 agentic-context strip (which drops `reasoning_content` from tool-call assistant turns to avoid O(n²) token growth) ran unconditionally, so replay providers (DeepSeek V4, Kimi K2, Qwen-Thinking, etc.) lost the client's reasoning and the reasoning-replay cache then overwrote it with a stale cached value (and such upstreams 400 without the original reasoning). The strip now skips reasoning-replay targets while non-reasoning providers keep the O(n²) protection.

([#5136](https://github.com/diegosouzapw/OmniRoute/pull/5136), closes [#3321](https://github.com/diegosouzapw/OmniRoute/issues/3321))
+- **fix(dashboard): key model-visibility toggle on the canonical `providerId`** — the per-model visibility toggle keyed off a display id, so toggling a model on one provider alias could mis-target another; it now keys on the canonical `providerId`. ([#5091](https://github.com/diegosouzapw/OmniRoute/pull/5091) — thanks @Theadd)
+- **fix(diagnostics): recognize the Claude API format in `detectMalformedNonStream`** — salvaged null-guard so a Claude-shaped non-streaming body is no longer misclassified. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @herjarsa / @diegosouzapw)
+- **fix(logging): track the final connection IDs in failover logs** — failover log lines now record the connection that actually served (or last failed) the request, instead of only the first attempt. ([#5016](https://github.com/diegosouzapw/OmniRoute/pull/5016) — thanks @JxnLexn)
+- **fix(sse): ignore disconnect races during in-band stream error handling** — a client disconnect that races with in-band upstream error handling no longer surfaces as a spurious provider failure. ([#5007](https://github.com/diegosouzapw/OmniRoute/pull/5007) — thanks @JxnLexn)
+- **fix(dashboard): surface the server error on `handleToggleCombo` failure** — a failed combo toggle now shows the backend error instead of silently no-op'ing. ([#5138](https://github.com/diegosouzapw/OmniRoute/pull/5138) — thanks @KooshaPari / @diegosouzapw)
+- **fix(quota): track provider quota reset windows + enrich the Codex playground** — observed quota reset windows are tracked and surfaced, and the Codex playground gains the enriched quota metadata. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @Witroch4 / @diegosouzapw)
+- **fix(sidebar): drop the orphan `settings` accent color** — removed a dangling accent-color entry that broke `typecheck:core`. ([#5142](https://github.com/diegosouzapw/OmniRoute/pull/5142))
+
+### 🔒 Security

+- **fix(security): exact-host Anthropic `baseUrl` check** — the Anthropic base-URL guard used a substring match that a crafted host could partially satisfy; it now requires an exact host match (resolves CodeQL `js/incomplete-url-substring-sanitization` alert #674).

 ### 🔧 Bug Fixes
 
@@ -55,14 +58,32 @@ _In development — bullets added per PR; finalized at release._
 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on). The redundant cleanup is removed (per-model removal already handles its own compat cleanup), so eye-hidden models stay hidden across re-sync. (#4389, thanks @herjarsa)

([#5086](https://github.com/diegosouzapw/OmniRoute/pull/5086) — thanks @herjarsa)
 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format). (thanks @StevanusPangau)
-- **fix(translator): stop stripping client-provided `reasoning_content` for reasoning-replay providers** — the #4849 agentic-context strip (which drops `reasoning_content` from tool-call assistant turns to avoid O(n²) token growth) ran unconditionally, so replay providers (DeepSeek V4, Kimi K2, Qwen-Thinking, etc.) lost the client's reasoning and the reasoning-replay cache then overwrote it with a stale cached value (and such upstreams 400 without the original reasoning). The strip now skips reasoning-replay targets while non-reasoning providers keep the O(n²) protection.

([#5136](https://github.com/diegosouzapw/OmniRoute/pull/5136), closes [#3321](https://github.com/diegosouzapw/OmniRoute/issues/3321))
+- **fix(dashboard): key model-visibility toggle on the canonical `providerId`** — the per-model visibility toggle keyed off a display id, so toggling a model on one provider alias could mis-target another; it now keys on the canonical `providerId`. ([#5091](https://github.com/diegosouzapw/OmniRoute/pull/5091) — thanks @Theadd)
+- **fix(diagnostics): recognize the Claude API format in `detectMalformedNonStream`** — salvaged null-guard so a Claude-shaped non-streaming body is no longer misclassified. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @herjarsa / @diegosouzapw)
+- **fix(logging): track the final connection IDs in failover logs** — failover log lines now record the connection that actually served (or last failed) the request, instead of only the first attempt. ([#5016](https://github.com/diegosouzapw/OmniRoute/pull/5016) — thanks @JxnLexn)
+- **fix(sse): ignore disconnect races during in-band stream error handling** — a client disconnect that races with in-band upstream error handling no longer surfaces as a spurious provider failure. ([#5007](https://github.com/diegosouzapw/OmniRoute/pull/5007) — thanks @JxnLexn)
+- **fix(dashboard): surface the server error on `handleToggleCombo` failure** — a failed combo toggle now shows the backend error instead of silently no-op'ing. ([#5138](https://github.com/diegosouzapw/OmniRoute/pull/5138) — thanks @KooshaPari / @diegosouzapw)
+- **fix(quota): track provider quota reset windows + enrich the Codex playground** — observed quota reset windows are tracked and surfaced, and the Codex playground gains the enriched quota metadata. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @Witroch4 / @diegosouzapw)
+- **fix(sidebar): drop the orphan `settings` accent color** — removed a dangling accent-color entry that broke `typecheck:core`. ([#5142](https://github.com/diegosouzapw/OmniRoute/pull/5142))

+- **fix(security): exact-host Anthropic `baseUrl` check** — the Anthropic base-URL guard used a substring match that a crafted host could partially satisfy; it now requires an exact host match (resolves CodeQL `js/incomplete-url-substring-sanitization` alert #674).

 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on). The redundant cleanup is removed (per-model removal already handles its own compat cleanup), so eye-hidden models stay hidden across re-sync. (#4389, thanks @herjarsa)

([#5086](https://github.com/diegosouzapw/OmniRoute/pull/5086) — thanks @herjarsa)
 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format). (thanks @StevanusPangau)
-- **fix(translator): stop stripping client-provided `reasoning_content` for reasoning-replay providers** — the #4849 agentic-context strip (which drops `reasoning_content` from tool-call assistant turns to avoid O(n²) token growth) ran unconditionally, so replay providers (DeepSeek V4, Kimi K2, Qwen-Thinking, etc.) lost the client's reasoning and the reasoning-replay cache then overwrote it with a stale cached value (and such upstreams 400 without the original reasoning). The strip now skips reasoning-replay targets while non-reasoning providers keep the O(n²) protection.

+- **fix(dashboard): key model-visibility toggle on the canonical `providerId`** — the per-model visibility toggle keyed off a display id, so toggling a model on one provider alias could mis-target another; it now keys on the canonical `providerId`. ([#5091](https://github.com/diegosouzapw/OmniRoute/pull/5091) — thanks @Theadd)

+- **fix(logging): track the final connection IDs in failover logs** — failover log lines now record the connection that actually served (or last failed) the request, instead of only the first attempt. ([#5016](https://github.com/diegosouzapw/OmniRoute/pull/5016) — thanks @JxnLexn)
+- **fix(sse): ignore disconnect races during in-band stream error handling** — a client disconnect that races with in-band upstream error handling no longer surfaces as a spurious provider failure. ([#5007](https://github.com/diegosouzapw/OmniRoute/pull/5007) — thanks @JxnLexn)
+- **fix(dashboard): surface the server error on `handleToggleCombo` failure** — a failed combo toggle now shows the backend error instead of silently no-op'ing. ([#5138](https://github.com/diegosouzapw/OmniRoute/pull/5138) — thanks @KooshaPari / @diegosouzapw)
+- **fix(quota): track provider quota reset windows + enrich the Codex playground** — observed quota reset windows are tracked and surfaced, and the Codex playground gains the enriched quota metadata. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @Witroch4 / @diegosouzapw)

 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format). (thanks @StevanusPangau)
-- **fix(translator): stop stripping client-provided `reasoning_content` for reasoning-replay providers** — the #4849 agentic-context strip (which drops `reasoning_content` from tool-call assistant turns to avoid O(n²) token growth) ran unconditionally, so replay providers (DeepSeek V4, Kimi K2, Qwen-Thinking, etc.) lost the client's reasoning and the reasoning-replay cache then overwrote it with a stale cached value (and such upstreams 400 without the original reasoning).

 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout.

Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format).

 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on).

(thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)

 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on). The redundant cleanup is removed (per-model removal already handles its own compat cleanup), so eye-hidden models stay hidden across re-sync. (#4389, thanks @herjarsa)

([#5086](https://github.com/diegosouzapw/OmniRoute/pull/5086) — thanks @herjarsa)
 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format).

 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on). The redundant cleanup is removed (per-model removal already handles its own compat cleanup), so eye-hidden models stay hidden across re-sync. (#4389, thanks @herjarsa)

([#5086](https://github.com/diegosouzapw/OmniRoute/pull/5086) — thanks @herjarsa)
 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format). (thanks @StevanusPangau)
-- **fix(translator): stop stripping client-provided `reasoning_content` for reasoning-replay providers** — the #4849 agentic-context strip (which drops `reasoning_content` from tool-call assistant turns to avoid O(n²) token growth) ran unconditionally, so replay providers (DeepSeek V4, Kimi K2, Qwen-Thinking, etc.) lost the client's reasoning and the reasoning-replay cache then overwrote it with a stale cached value (and such upstreams 400 without the original reasoning). The strip now skips reasoning-replay targets while non-reasoning providers keep the O(n²) protection.

 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on). The redundant cleanup is removed (per-model removal already handles its own compat cleanup), so eye-hidden models stay hidden across re-sync. (#4389, thanks @herjarsa)

([#5086](https://github.com/diegosouzapw/OmniRoute/pull/5086) — thanks @herjarsa)
 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format). (thanks @StevanusPangau)
-- **fix(translator): stop stripping client-provided `reasoning_content` for reasoning-replay providers** — the #4849 agentic-context strip (which drops `reasoning_content` from tool-call assistant turns to avoid O(n²) token growth) ran unconditionally, so replay providers (DeepSeek V4, Kimi K2, Qwen-Thinking, etc.) lost the client's reasoning and the reasoning-replay cache then overwrote it with a stale cached value (and such upstreams 400 without the original reasoning). The strip now skips reasoning-replay targets while non-reasoning providers keep the O(n²) protection.

([#5136](https://github.com/diegosouzapw/OmniRoute/pull/5136), closes [#3321](https://github.com/diegosouzapw/OmniRoute/issues/3321))
+- **fix(dashboard): key model-visibility toggle on the canonical `providerId`** — the per-model visibility toggle keyed off a display id, so toggling a model on one provider alias could mis-target another; it now keys on the canonical `providerId`. ([#5091](https://github.com/diegosouzapw/OmniRoute/pull/5091) — thanks @Theadd)
+- **fix(diagnostics): recognize the Claude API format in `detectMalformedNonStream`** — salvaged null-guard so a Claude-shaped non-streaming body is no longer misclassified. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @herjarsa / @diegosouzapw)
+- **fix(logging): track the final connection IDs in failover logs** — failover log lines now record the connection that actually served (or last failed) the request, instead of only the first attempt. ([#5016](https://github.com/diegosouzapw/OmniRoute/pull/5016) — thanks @JxnLexn)
+- **fix(sse): ignore disconnect races during in-band stream error handling** — a client disconnect that races with in-band upstream error handling no longer surfaces as a spurious provider failure. ([#5007](https://github.com/diegosouzapw/OmniRoute/pull/5007) — thanks @JxnLexn)
+- **fix(dashboard): surface the server error on `handleToggleCombo` failure** — a failed combo toggle now shows the backend error instead of silently no-op'ing. ([#5138](https://github.com/diegosouzapw/OmniRoute/pull/5138) — thanks @KooshaPari / @diegosouzapw)
+- **fix(quota): track provider quota reset windows + enrich the Codex playground** — observed quota reset windows are tracked and surfaced, and the Codex playground gains the enriched quota metadata. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @Witroch4 / @diegosouzapw)

 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on). The redundant cleanup is removed (per-model removal already handles its own compat cleanup), so eye-hidden models stay hidden across re-sync. (#4389, thanks @herjarsa)

([#5086](https://github.com/diegosouzapw/OmniRoute/pull/5086) — thanks @herjarsa)
 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format). (thanks @StevanusPangau)
-- **fix(translator): stop stripping client-provided `reasoning_content` for reasoning-replay providers** — the #4849 agentic-context strip (which drops `reasoning_content` from tool-call assistant turns to avoid O(n²) token growth) ran unconditionally, so replay providers (DeepSeek V4, Kimi K2, Qwen-Thinking, etc.) lost the client's reasoning and the reasoning-replay cache then overwrote it with a stale cached value (and such upstreams 400 without the original reasoning). The strip now skips reasoning-replay targets while non-reasoning providers keep the O(n²) protection.

([#5136](https://github.com/diegosouzapw/OmniRoute/pull/5136), closes [#3321](https://github.com/diegosouzapw/OmniRoute/issues/3321))
+- **fix(dashboard): key model-visibility toggle on the canonical `providerId`** — the per-model visibility toggle keyed off a display id, so toggling a model on one provider alias could mis-target another; it now keys on the canonical `providerId`. ([#5091](https://github.com/diegosouzapw/OmniRoute/pull/5091) — thanks @Theadd)
+- **fix(diagnostics): recognize the Claude API format in `detectMalformedNonStream`** — salvaged null-guard so a Claude-shaped non-streaming body is no longer misclassified. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @herjarsa / @diegosouzapw)
+- **fix(logging): track the final connection IDs in failover logs** — failover log lines now record the connection that actually served (or last failed) the request, instead of only the first attempt. ([#5016](https://github.com/diegosouzapw/OmniRoute/pull/5016) — thanks @JxnLexn)
+- **fix(sse): ignore disconnect races during in-band stream error handling** — a client disconnect that races with in-band upstream error handling no longer surfaces as a spurious provider failure. ([#5007](https://github.com/diegosouzapw/OmniRoute/pull/5007) — thanks @JxnLexn)
+- **fix(dashboard): surface the server error on `handleToggleCombo` failure** — a failed combo toggle now shows the backend error instead of silently no-op'ing. ([#5138](https://github.com/diegosouzapw/OmniRoute/pull/5138) — thanks @KooshaPari / @diegosouzapw)
+- **fix(quota): track provider quota reset windows + enrich the Codex playground** — observed quota reset windows are tracked and surfaced, and the Codex playground gains the enriched quota metadata. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @Witroch4 / @diegosouzapw)
+- **fix(sidebar): drop the orphan `settings` accent color** — removed a dangling accent-color entry that broke `typecheck:core`. ([#5142](https://github.com/diegosouzapw/OmniRoute/pull/5142))
+
+### 🔒 Security
+
+- **fix(security): exact-host Anthropic `baseUrl` check** — the Anthropic base-URL guard used a substring match that a crafted host could partially satisfy; it now requires an exact host match (resolves CodeQL `js/incomplete-url-substring-sanitization` alert #674).

@@ -55,14 +58,32 @@ _In development — bullets added per PR; finalized at release._
 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on). The redundant cleanup is removed (per-model removal already handles its own compat cleanup), so eye-hidden models stay hidden across re-sync. (#4389, thanks @herjarsa)

([#5086](https://github.com/diegosouzapw/OmniRoute/pull/5086) — thanks @herjarsa)
 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format). (thanks @StevanusPangau)
-- **fix(translator): stop stripping client-provided `reasoning_content` for reasoning-replay providers** — the #4849 agentic-context strip (which drops `reasoning_content` from tool-call assistant turns to avoid O(n²) token growth) ran unconditionally, so replay providers (DeepSeek V4, Kimi K2, Qwen-Thinking, etc.) lost the client's reasoning and the reasoning-replay cache then overwrote it with a stale cached value (and such upstreams 400 without the original reasoning). The strip now skips reasoning-replay targets while non-reasoning providers keep the O(n²) protection.

([#5136](https://github.com/diegosouzapw/OmniRoute/pull/5136), closes [#3321](https://github.com/diegosouzapw/OmniRoute/issues/3321))
+- **fix(dashboard): key model-visibility toggle on the canonical `providerId`** — the per-model visibility toggle keyed off a display id, so toggling a model on one provider alias could mis-target another; it now keys on the canonical `providerId`. ([#5091](https://github.com/diegosouzapw/OmniRoute/pull/5091) — thanks @Theadd)
+- **fix(diagnostics): recognize the Claude API format in `detectMalformedNonStream`** — salvaged null-guard so a Claude-shaped non-streaming body is no longer misclassified. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @herjarsa / @diegosouzapw)
+- **fix(logging): track the final connection IDs in failover logs** — failover log lines now record the connection that actually served (or last failed) the request, instead of only the first attempt. ([#5016](https://github.com/diegosouzapw/OmniRoute/pull/5016) — thanks @JxnLexn)
+- **fix(sse): ignore disconnect races during in-band stream error handling** — a client disconnect that races with in-band upstream error handling no longer surfaces as a spurious provider failure. ([#5007](https://github.com/diegosouzapw/OmniRoute/pull/5007) — thanks @JxnLexn)
+- **fix(dashboard): surface the server error on `handleToggleCombo` failure** — a failed combo toggle now shows the backend error instead of silently no-op'ing. ([#5138](https://github.com/diegosouzapw/OmniRoute/pull/5138) — thanks @KooshaPari / @diegosouzapw)
+- **fix(quota): track provider quota reset windows + enrich the Codex playground** — observed quota reset windows are tracked and surfaced, and the Codex playground gains the enriched quota metadata. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @Witroch4 / @diegosouzapw)
+- **fix(sidebar): drop the orphan `settings` accent color** — removed a dangling accent-color entry that broke `typecheck:core`. ([#5142](https://github.com/diegosouzapw/OmniRoute/pull/5142))

+### 🔒 Security

+- **fix(security): exact-host Anthropic `baseUrl` check** — the Anthropic base-URL guard used a substring match that a crafted host could partially satisfy; it now requires an exact host match (resolves CodeQL `js/incomplete-url-substring-sanitization` alert #674).

 ### 🔧 Bug Fixes
 
@@ -55,14 +58,32 @@ _In development — bullets added per PR; finalized at release._
 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on). The redundant cleanup is removed (per-model removal already handles its own compat cleanup), so eye-hidden models stay hidden across re-sync. (#4389, thanks @herjarsa)

([#5086](https://github.com/diegosouzapw/OmniRoute/pull/5086) — thanks @herjarsa)
 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format). (thanks @StevanusPangau)
-- **fix(translator): stop stripping client-provided `reasoning_content` for reasoning-replay providers** — the #4849 agentic-context strip (which drops `reasoning_content` from tool-call assistant turns to avoid O(n²) token growth) ran unconditionally, so replay providers (DeepSeek V4, Kimi K2, Qwen-Thinking, etc.) lost the client's reasoning and the reasoning-replay cache then overwrote it with a stale cached value (and such upstreams 400 without the original reasoning). The strip now skips reasoning-replay targets while non-reasoning providers keep the O(n²) protection.

([#5136](https://github.com/diegosouzapw/OmniRoute/pull/5136), closes [#3321](https://github.com/diegosouzapw/OmniRoute/issues/3321))
+- **fix(dashboard): key model-visibility toggle on the canonical `providerId`** — the per-model visibility toggle keyed off a display id, so toggling a model on one provider alias could mis-target another; it now keys on the canonical `providerId`. ([#5091](https://github.com/diegosouzapw/OmniRoute/pull/5091) — thanks @Theadd)
+- **fix(diagnostics): recognize the Claude API format in `detectMalformedNonStream`** — salvaged null-guard so a Claude-shaped non-streaming body is no longer misclassified. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @herjarsa / @diegosouzapw)
+- **fix(logging): track the final connection IDs in failover logs** — failover log lines now record the connection that actually served (or last failed) the request, instead of only the first attempt. ([#5016](https://github.com/diegosouzapw/OmniRoute/pull/5016) — thanks @JxnLexn)
+- **fix(sse): ignore disconnect races during in-band stream error handling** — a client disconnect that races with in-band upstream error handling no longer surfaces as a spurious provider failure. ([#5007](https://github.com/diegosouzapw/OmniRoute/pull/5007) — thanks @JxnLexn)
+- **fix(dashboard): surface the server error on `handleToggleCombo` failure** — a failed combo toggle now shows the backend error instead of silently no-op'ing. ([#5138](https://github.com/diegosouzapw/OmniRoute/pull/5138) — thanks @KooshaPari / @diegosouzapw)
+- **fix(quota): track provider quota reset windows + enrich the Codex playground** — observed quota reset windows are tracked and surfaced, and the Codex playground gains the enriched quota metadata. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @Witroch4 / @diegosouzapw)
+- **fix(sidebar): drop the orphan `settings` accent color** — removed a dangling accent-color entry that broke `typecheck:core`. ([#5142](https://github.com/diegosouzapw/OmniRoute/pull/5142))

+- **fix(security): exact-host Anthropic `baseUrl` check** — the Anthropic base-URL guard used a substring match that a crafted host could partially satisfy; it now requires an exact host match (resolves CodeQL `js/incomplete-url-substring-sanitization` alert #674).

 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on).

([#5086](https://github.com/diegosouzapw/OmniRoute/pull/5086) — thanks @herjarsa)
 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format). (thanks @StevanusPangau)
-- **fix(translator): stop stripping client-provided `reasoning_content` for reasoning-replay providers** — the #4849 agentic-context strip (which drops `reasoning_content` from tool-call assistant turns to avoid O(n²) token growth) ran unconditionally, so replay providers (DeepSeek V4, Kimi K2, Qwen-Thinking, etc.) lost the client's reasoning and the reasoning-replay cache then overwrote it with a stale cached value (and such upstreams 400 without the original reasoning). The strip now skips reasoning-replay targets while non-reasoning providers keep the O(n²) protection.

+- **fix(dashboard): key model-visibility toggle on the canonical `providerId`** — the per-model visibility toggle keyed off a display id, so toggling a model on one provider alias could mis-target another; it now keys on the canonical `providerId`. ([#5091](https://github.com/diegosouzapw/OmniRoute/pull/5091) — thanks @Theadd)

+- **fix(logging): track the final connection IDs in failover logs** — failover log lines now record the connection that actually served (or last failed) the request, instead of only the first attempt. ([#5016](https://github.com/diegosouzapw/OmniRoute/pull/5016) — thanks @JxnLexn)
+- **fix(sse): ignore disconnect races during in-band stream error handling** — a client disconnect that races with in-band upstream error handling no longer surfaces as a spurious provider failure. ([#5007](https://github.com/diegosouzapw/OmniRoute/pull/5007) — thanks @JxnLexn)
+- **fix(dashboard): surface the server error on `handleToggleCombo` failure** — a failed combo toggle now shows the backend error instead of silently no-op'ing. ([#5138](https://github.com/diegosouzapw/OmniRoute/pull/5138) — thanks @KooshaPari / @diegosouzapw)
+- **fix(quota): track provider quota reset windows + enrich the Codex playground** — observed quota reset windows are tracked and surfaced, and the Codex playground gains the enriched quota metadata. ([#5141](https://github.com/diegosouzapw/OmniRoute/pull/5141) — thanks @Witroch4 / @diegosouzapw)

 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format). (thanks @StevanusPangau)
-- **fix(translator): stop stripping client-provided `reasoning_content` for reasoning-replay providers** — the #4849 agentic-context strip (which drops `reasoning_content` from tool-call assistant turns to avoid O(n²) token growth) ran unconditionally, so replay providers (DeepSeek V4, Kimi K2, Qwen-Thinking, etc.) lost the client's reasoning and the reasoning-replay cache then overwrote it with a stale cached value (and such upstreams 400 without the original reasoning).

 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout.

Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format).

 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on).

(thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)

 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on). The redundant cleanup is removed (per-model removal already handles its own compat cleanup), so eye-hidden models stay hidden across re-sync. (#4389, thanks @herjarsa)

([#5086](https://github.com/diegosouzapw/OmniRoute/pull/5086) — thanks @herjarsa)
 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format).

 - **feat(cc): per-connection "summarized thinking display" toggle for Claude-Code-compatible providers** — exposes a connection-level toggle that drives the existing Copilot summarized-thinking marker, so operators can opt a CC-compatible connection into summarized reasoning display from the UI (schema + request defaults + provider modals, with i18n). (thanks @rdself)
 - **feat(compression): compression playground in the studio (Play + Compare tabs)** — `/dashboard/compression/studio` gains a synthetic playground: paste text → per-engine **lanes** (each deterministic engine run alone via `/api/compression/preview`) plus a **combined waterfall** ordered by `stackPriority`, and a free **A/B Compare** grid with on-demand, **USD-capped** fidelity verdicts (`/api/compression/compare` + `compare/verify`). The preview route now uses the real cl100k tokenizer, returns `engineBreakdown`, and accepts an ordered `pipeline[]`; new `compare` / `compare/verify` / `retrieve` routes; the live WS feed moved to `/dashboard/compression/live`. Management-only. ([#5080](https://github.com/diegosouzapw/OmniRoute/pull/5080))
 - **feat(dashboard): expose Fusion `judgeModel` + `fusionTuning` in the combo editor** — the Fusion strategy editor now surfaces the judge model (synthesizes the panel answers; defaults to the first panel model) plus the quorum-grace tuning fields (`minPanel`, `stragglerGraceMs`, `panelHardTimeoutMs`) that `open-sse/services/fusion.ts` already reads. Schema-validated + bounded; empty tuning is never persisted. ([#5074](https://github.com/diegosouzapw/OmniRoute/pull/5074))
+- **feat(compression): opt-in per-step fidelity gate for the stacked pipeline** — each compression step can now be guarded by a pure fidelity checker (4 invariants, fail-open) so a lossy engine that would degrade the prompt past a threshold is rejected and its lane skipped instead of silently shipping. Configurable via `fidelityGate` (advanced thresholds intentionally API-omitted), with a per-lane rejection breakdown surfaced in the studio playground toggle. ([#5143](https://github.com/diegosouzapw/OmniRoute/pull/5143))
+- **feat(compression): fuzzy near-duplicate dedup (session-dedup 2nd pass)** — the session-dedup engine gains a second fuzzy pass that collapses near-duplicate (not just byte-identical) segments, with a playground toggle to compare on/off. ([#5143](https://github.com/diegosouzapw/OmniRoute/pull/5143))
+- **feat(quota): opt-in Codex/Claude auto-ping keepalive** — an opt-in background keepalive can periodically ping Codex/Claude connections to keep their session/quota state warm, reducing cold-start failures on the first real request. ([#5102](https://github.com/diegosouzapw/OmniRoute/pull/5102))
+- **feat(ops): SRE playbooks + ops helper scripts** — salvaged from a closed stale PR; adds operator runbooks and ops helper scripts. ([#5138](https://github.com/diegosouzapw/OmniRoute/pull/5138) — thanks @KooshaPari / @diegosouzapw)
+- **feat(mcp): web-session robustness — cookie dedup + browser-pool observability** — the MCP web-session path now de-duplicates cookies when (re)hydrating a session (avoiding conflicting duplicate `Cookie` headers) and exposes browser-pool observability (pool size / in-use / acquisition metrics) for the headless web providers. ([#5121](https://github.com/diegosouzapw/OmniRoute/pull/5121), builds on [#3368](https://github.com/diegosouzapw/OmniRoute/issues/3368))
 
 ### 🔧 Bug Fixes
 
@@ -55,14 +58,32 @@ _In development — bullets added per PR; finalized at release._
 - **fix(sse): don't cool down a healthy connection on a self-inflicted upstream timeout (504)** — when OmniRoute's own deadline elapses (surfaced as `TimeoutError`/`BodyTimeoutError` → 504), the connection is no longer disabled/failed-over, so a slow-but-healthy provider isn't penalised for our timeout. Genuine upstream 5xx/429 still trigger cooldown; antigravity keeps its own policy. (thanks @costaeder)
 - **fix(translator):** forward image `tool_result` blocks as `image_url` instead of stringifying base64. (thanks @alican532)
 - **fix(sse): robust Anthropic `/v1/messages` streaming — real ping keepalive + client-disconnect guard** — slow first tokens on reasoning models could trip strict clients' idle-read watchdog; the route now keeps the stream warm with a real `event: ping` (Anthropic clients ignore SSE comments) from the very first frame, and a client disconnect (AbortError / controller-closed) no longer counts as a provider failure (no failover/cooldown). (thanks @costaeder)
-- **fix: preserve model hidden flags (`isHidden`) across model sync** — `replaceCustomModels` pruned the compat-override list to the new custom-model ids, silently wiping the `isHidden` flag of eye-hidden SYNCED models on every periodic sync / import (all hidden models turned back on). The redundant cleanup is removed (per-model removal already handles its own compat cleanup), so eye-hidden models stay hidden across re-sync. (#4389, thanks @herjarsa)

([#5086](https://github.com/diegosouzapw/OmniRoute/pull/5086) — thanks @herjarsa)
 - **fix(models): derive model-discovery config from the registry `modelsUrl`** — providers absent from the hardcoded `PROVIDER_MODELS_CONFIG` but carrying a registry `modelsUrl` (e.g. MiniMax) now get an auto-derived Bearer `/v1/models` discovery config, so "discover models" works instead of returning nothing. (thanks @herjarsa)
 - **fix(compression): resolve worker + rule/filter assets via runtime anchors (standalone bundle)** — the LLMLingua worker and the RTK rule/filter loaders relied on `fileURLToPath(import.meta.url)`, which the standalone bundle freezes to the build-machine path, so the worker never spawned and rule/filter packs failed to resolve. They now anchor on `process.cwd()`/`argv[1]` (with `pathToFileURL` for the worker URL). (thanks @fulorgnas)
 - **fix(api): sanitize error responses on seven management routes (Rule #12 hardening)** — `cli-tools/backups`, `cli-tools/guide-settings/[toolId]`, `logs/export`, `models/catalog`, `providers/test-batch`, `settings/import-json` and `usage/proxy-logs` no longer return raw `error.message`; they wrap caught errors in `sanitizeErrorMessage(...)`, and the routes are removed from the `check-error-helper` allowlist. (thanks @JxnLexn)
 - **fix(sse): keep `output_text`-only Responses bodies from being dropped/false-502'd** — some upstreams return a shorthand Responses body whose answer is only in `output_text` with an empty `output[]`. `sanitizeResponsesApiResponse` discarded the text, so the response then tripped the malformed-200 guard. The sanitizer now synthesizes an `output[]` message item from a non-empty `output_text` (complements the Claude-native fix in #5108; both stem from #4942).
 - **fix(executors): preserve a lone caller-supplied `Anthropic-Version` header casing** — the case-variant dedupe (#4846) unconditionally rewrote `Anthropic-Version`/`Anthropic-Beta` to lowercase even when only one variant was present, clobbering the caller's header. Dedupe now runs only when both case variants coexist (the actual undici-merge collision it was meant to fix).
 - **fix(responses):** default `text.format` to `{ type: "text" }` for openai-compatible **responses** providers — some Responses-compatible upstreams (e.g. LM Studio) reject a `text` object missing `text.format` with a 400 `missing_required_parameter`; the default executor now fills the Responses-API default before forwarding (guarded to `openai-compatible-*responses*`, never overwriting an existing format). (thanks @StevanusPangau)
-- **fix(translator): stop stripping client-provided `reasoning_content` for reasoning-replay providers** — the #4849 agentic-context strip (which drops `reasoning_content` from tool-call assistant turns to avoid O(n²) token growth) ran unconditionally, so replay providers (DeepSeek V4, Kimi K2, Qwen-Thinking, etc.) lost the client's reasoning and the reasoning-replay cache then overwrote it with a stale cached value (and such upstreams 400 without the original reasoning). The strip now skips reasoning-replay targets while non-reasoning providers keep the O(n²) protection.
