https://unifiedharnessprotocol.dev/ Independent Unified Harness Protocol release, adoption and technical updates. en Sun, 04 Oct 2026 12:29:22 GMT https://unifiedharnessprotocol.dev/uhp-guide-refinement-v2-2026-10-04Sun, 04 Oct 2026 12:29:22 GMTThe independent guide adds substantive task and decision guidance across its 109 routes, organizes the reference into seven reader-oriented subject groups, and provides a local interface chooser. Source reviews distinguish stable releases, development revisions and historical evidence; unavailable current normative detail remains explicitly unresolved. https://unifiedharnessprotocol.dev/uhp-guide-overhaul-2026-10-04Sun, 04 Oct 2026 09:38:57 GMTThe independent guide now separates current setup advice from historical release evidence, adds task-focused entry paths, improves keyboard-accessible reference tables and distinguishes protocol versions, software releases and conformance measurements. Qwen Live, NeMo Relay and protocol comparisons have refreshed practical guidance. https://unifiedharnessprotocol.dev/releases/uhp-news-harnessrouter-v0.29.1-2026-10-04Sun, 04 Oct 2026 15:17:35 GMTHarnessRouter v0.29.1 forwards provider streams as data arrives, makes event-level upstream silence time out even when keep-alive lines continue, applies the same relay liveness rules to DeepSeek Harness, and fixes RC publication semantics. UHP remains 2026-09-28, conformance remains 2026.9.28.post3 with 85 executable checks, and the released backend count remains 20. https://unifiedharnessprotocol.dev/releases/uhp-news-harnessrouter-v0.29.0-2026-10-04Sun, 04 Oct 2026 00:33:05 GMTHarnessRouter v0.29.0 adds Kilo CLI, MiniMax Code, Grok Build and Agent Zero, taking the released backend set from 16 to 20, together with relay and secret-handling hardening. UHP remains 2026-09-28 and conformance remains 2026.9.28.post3 with 85 executable checks. https://unifiedharnessprotocol.dev/oh-my-pi/uhp-news-oh-my-pi-v18.1.19-2026-09-12Sat, 12 Sep 2026 23:57:09 GMTOh My Pi v18.1.19 promotes the tracked MCP reconnect, DeepSeek V4.1 Flash, replay-safe retry, per-fallback reasoning effort, persistent context-isolated /btw and JSON print-mode exit-status work into stable behavior and adds live-tool, provider-auth and Windows reliability fixes. HarnessRouter v0.16.1 still measures OMP 18.1.13; upstream latest and adapter evidence remain separate coordinates. https://unifiedharnessprotocol.dev/harness-plugins/uhp-news-2026-09-12-harness-pluginsSat, 12 Sep 2026 23:40:40 GMTUHP 2026-09-12 adds optional Harness Plugins using Agent Plugins 1.0.0 as the package format and advances the conformance package to 2026.9.12 with 74 checks. The checked-in HarnessRouter reference result remains the prior-suite 64/64 Full run; PR #165 says Community Edition still reports plugins unsupported at that merge point, so no 74/74 runtime result is claimed. https://unifiedharnessprotocol.dev/releases/uhp-news-harnessrouter-v0.16.1-custom-endpoint-controls-2026-09-11Fri, 11 Sep 2026 07:28:18 GMTHarnessRouter v0.16.1 releases PR #155: custom endpoint model rows become explicit per-connection canonical-to-wire mappings, custom endpoints gain OpenAI Responses format, connection-level disabled tools are applied per turn, and Codex is pinned to 0.154.0. UHP remains 2026-08-11, the backend set remains ten and conformance remains 64 checks. https://unifiedharnessprotocol.dev/releases/uhp-news-harnessrouter-v0.16.0-hosted-provider-2026-09-11Fri, 11 Sep 2026 04:52:35 GMTHarnessRouter v0.16.0 releases PR #151 and lets self-hosted Community Edition pair with HarnessRouter API as an optional provider through a server-mediated key hand-off. The gateway keeps pairing and provider credentials server-side, stores the hosted endpoint and model-catalog coordinates, and preserves hosted routing for Gemini. UHP remains 2026-08-11, the backend set remains ten, and conformance remains 64 checks. https://unifiedharnessprotocol.dev/releases/uhp-news-harnessrouter-v0.15.10-codex-app-server-2026-09-10Thu, 10 Sep 2026 09:07:08 GMTHarnessRouter v0.15.8-v0.15.10 normalize Codex app-server item spelling, make app-server the default execution path with an explicit codex-exec rollback, and turn cross-route encrypted-reasoning continuation refusal into an actionable provider error. Post-release PR #148 reruns the Codex provider columns on the app-server path and records 43/44 Vercel, 43/44 TokenRouter, 44/44 OpenAI, 44/44 Azure and 43/44 OpenRouter. These are HarnessRouter runtime/provider compatibility results, not UHP conformance. https://unifiedharnessprotocol.dev/releases/uhp-news-harnessrouter-v0.15.7-resume-hermes-azure-2026-09-08Tue, 08 Sep 2026 19:31:35 GMTHarnessRouter v0.15.7 releases PR #139. Later GPT-family models such as gpt-6-astra on Azure Foundry are routed through Hermes Responses mode, while missing Claude Code or OpenCode native sessions emit an explicit lost-resume signal and fail the support-matrix recall verdict instead of passing as fresh continuity. UHP remains 2026-08-11, conformance remains 64 checks and the released backend set remains ten. https://unifiedharnessprotocol.dev/releases/uhp-news-harnessrouter-v0.15.6-dsh-mcp-verification-2026-09-08Tue, 08 Sep 2026 13:31:18 GMTHarnessRouter v0.15.6 releases runtime and verification hardening from PRs #135-#138. The DeepSeek Harness adapter moves to 0.1.2rc1 with configured MCP-server driving, Oh My Pi tool/MCP metadata is corrected, runnable-model availability requires server evidence, and the custom-harness verification dimension now exercises a real MCP server across all ten built-in harness bases when its external endpoint is reachable. UHP remains 2026-08-11 and conformance remains 64 checks. https://unifiedharnessprotocol.dev/releases/uhp-news-harnessrouter-v0.15.5-verification-methodology-2026-09-08Tue, 08 Sep 2026 06:35:08 GMTHarnessRouter v0.15.5 is the latest stable release at that cutoff. v0.15.4-v0.15.5 refine README and Quickstart presentation without changing UHP, provider routing, ten-backend state or conformance. PR #133 adds explicit support-matrix and custom-harness verdict methodology; v0.15.6 later extends that implementation-level dimension to an MCP server. https://unifiedharnessprotocol.dev/releases/uhp-news-harnessrouter-v0.15.3-hosted-login-cookies-2026-09-08Tue, 08 Sep 2026 01:31:06 GMTHarnessRouter v0.15.3 releases hosted/shared-console authentication hardening from PRs #125 and #127: the bearer cookie is host-only, HttpOnly, Secure and SameSite=Lax; login cookies are reconciled from the current session and migration can validate either of two same-name cookies. The paths are explicitly inert self-hosted. UHP remains 2026-08-11, conformance remains 64 checks and the released backend set remains ten. https://unifiedharnessprotocol.dev/releases/uhp-news-harnessrouter-v0.15.2-ten-harnesses-artifact-evidence-2026-09-07Mon, 07 Sep 2026 23:09:55 GMTHarnessRouter v0.15.2 releases PRs #121-#123: artifact evidence now distinguishes rendered file-card count from older filename-only checks, README imagery reflects ten built-in harnesses, and gpt-6-astra is added on compatible routed provider/backend paths. UHP remains 2026-08-11 and conformance remains 64 checks. https://unifiedharnessprotocol.dev/releases/uhp-news-harnessrouter-v0.15.1-send-latch-file-card-2026-09-07Mon, 07 Sep 2026 21:27:13 GMTHarnessRouter v0.15.1 releases PR #120. A turn settling outside the POST stream no longer leaves later sends silently rejected, and the same produced file is de-duplicated when it arrives through both the POST stream and a late live-forward broadcast. https://unifiedharnessprotocol.dev/oh-my-pi/uhp-news-harnessrouter-v0.15.0-oh-my-pi-backend-2026-09-07Mon, 07 Sep 2026 17:43:08 GMTHarnessRouter v0.15.0 releases PR #68 and adds Oh My Pi as the tenth built-in harness backend. PR #119 separately records 705/705 OMP scenario runs across seven provider columns using Oh My Pi 18.1.13 under its stated pre-release conditions. This is HarnessRouter adapter evidence, not native Oh My Pi UHP adoption. https://unifiedharnessprotocol.dev/releases/uhp-news-harnessrouter-v0.14.5-deleted-task-gemini-helpers-2026-09-07Mon, 07 Sep 2026 05:31:43 GMTHarnessRouter v0.14.5 releases PR #117. Deleted and unknown session IDs are refused before work runs, owned tombstones can be deleted idempotently, continuation-read 503 failures use the protocol-defined server_error code, and all eighteen model-naming Gemini CLI 0.58.0 helper aliases are pinned to the turn model. UHP remains 2026-08-11 and conformance remains 64 checks. https://unifiedharnessprotocol.dev/gemini-cli/uhp-news-harnessrouter-v0.14.4-gemini-helper-model-2026-09-07Mon, 07 Sep 2026 04:48:00 GMTHarnessRouter v0.14.4 releases PR #116 after Gemini CLI housekeeping calls were observed using helper tiers that appeared as a second model in turn statistics. HarnessRouter pins those tiers to the turn model, carries the canonical model ID, and reports the runner error before result text on failure. https://unifiedharnessprotocol.dev/gemini-cli/uhp-news-harnessrouter-v0.14.3-gemini-tokenrouter-native-2026-09-07Mon, 07 Sep 2026 04:39:37 GMTHarnessRouter v0.14.3 releases PR #115. TokenRouter can serve the Gemini CLI backend through Google's native v1beta generate and stream API shape while preserving the vendor-table model identity and requested-versus-served checks. https://unifiedharnessprotocol.dev/gemini-cli/uhp-news-harnessrouter-v0.14.2-gemini-fallback-2026-09-07Mon, 07 Sep 2026 02:53:38 GMTHarnessRouter v0.14.2 releases PR #114. Each resolvable Gemini candidate chain now contains only the requested model, so provider retries stay on that model and provider failure ends the turn instead of silently falling back. Failed-turn reasons are kept separate from finished answer text. UHP remains 2026-08-11 and conformance remains 64 checks with the checked-in 64/64 Full reference result. https://unifiedharnessprotocol.dev/gemini-cli/uhp-news-harnessrouter-v0.14.1-gemini-default-2026-09-07Mon, 07 Sep 2026 02:43:47 GMTHarnessRouter v0.14.1 releases PR #113, adding the Gemini harness mark and changing the HarnessRouter Gemini default to gemini-3.8-flash across the catalogue, runner and console placeholder. This is a HarnessRouter product default, not a UHP protocol default. https://unifiedharnessprotocol.dev/gemini-cli/uhp-news-harnessrouter-v0.14.0-gemini-identity-2026-09-07Mon, 07 Sep 2026 00:44:54 GMTHarnessRouter v0.14.0 releases PR #111. The measured Gemini model identifiers are configured to serve as themselves, and a requested/observed serving-model mismatch fails instead of being counted as a successful compatibility turn. The PR records 11 measured Gemini IDs. UHP remains 2026-08-11 and conformance remains 64 checks with the checked-in 64/64 Full reference result. https://unifiedharnessprotocol.dev/gemini-cli/uhp-news-harnessrouter-v0.13.24-gemini-backend-2026-09-06Sun, 06 Sep 2026 23:16:54 GMTHarnessRouter v0.13.24 releases PR #72 and adds Gemini CLI as the ninth backend. HarnessRouter pins Gemini CLI 0.58.0 for the adapter, drives its stream-JSON mode and uses the direct Google API-key integration path. This is HarnessRouter adapter support, not native Google UHP adoption. https://unifiedharnessprotocol.dev/releases/uhp-news-harnessrouter-v0.13.25-v0.13.26-2026-09-07Mon, 07 Sep 2026 00:17:37 GMTv0.13.25 adds Gemini-family/provider support-matrix coverage and provider-aware backend integration selection through PRs #106 and #109. v0.13.26 releases PR #110, retrying a refused workspace restore for roughly 90 seconds and naming the refusal cause while retaining fail-closed behavior. https://unifiedharnessprotocol.dev/harnessrouter/uhp-news-harnessrouter-support-matrix-pr93-2026-09-06Sun, 06 Sep 2026 16:33:39 GMTHarnessRouter PR #93 publishes 695 harness-model pairs across eight provider columns, five scenarios per eligible pair and a separate 35-minute cold-recall probe across the eight then-released backends. This matrix predates the Gemini CLI backend and remains point-in-time HarnessRouter implementation evidence, not UHP conformance. https://unifiedharnessprotocol.dev/releases/uhp-news-harnessrouter-v0.13.11-v0.13.13-2026-09-06Sun, 06 Sep 2026 14:05:22 GMTHarnessRouter v0.13.11 through v0.13.13 harden direct-key Claude base normalization, provider-column support-matrix fidelity, fail-closed checkpoint restore and owner-trust Azure provider-base normalization. UHP remains 2026-08-11 and conformance remains 64 checks. https://unifiedharnessprotocol.dev/releases/uhp-news-harnessrouter-v0.13.10-2026-09-06Sun, 06 Sep 2026 10:23:14 GMTHarnessRouter v0.13.10 releases PR #86, adding an API-version path when the loopback relay receives a provider base without one. The change fixes direct-Anthropic Cline first turns and Qwen tool turns that had reached unversioned routes and returned 404 while preserving already-versioned and AWS-specific paths. https://unifiedharnessprotocol.dev/releases/uhp-news-harnessrouter-v0.13.5-google-ai-studio-2026-09-06Sun, 06 Sep 2026 02:16:47 GMTHarnessRouter v0.13.5 releases Google AI Studio as provider routing for Hermes, Pi, DeepSeek Harness, OpenCode, Qwen Code and Cline through Gemini's OpenAI-compatible endpoint. This provider path is separate from the dedicated Gemini CLI backend that later ships in v0.13.24. https://unifiedharnessprotocol.dev/conformance/uhp-news-harnessrouter-v0.13.3-64-of-64-2026-09-05Sat, 05 Sep 2026 00:21:52 GMTPR #64 incorporates the live 4 September 64/64 Full, zero-fail/skip/error HarnessRouter reference measurement into current protocol/conformance source. UHP remains 2026-08-11 and the suite remains 64 checks.
