feat(install.ps1): write .hermes-bootstrap-complete marker at end of install

The desktop app's main.cjs resolver ladder has a 'bootstrap-needed' rung
that fires when .hermes-bootstrap-complete is missing from
ACTIVE_HERMES_ROOT. Pre-Hermes-Setup, this marker was written by the
packaged-desktop's own bootstrap-runner.cjs at the end of its install
flow. Now that Hermes-Setup.exe runs install.ps1 directly, install.ps1
needs to own the marker — otherwise the desktop sees no marker on first
launch and triggers its legacy first-launch bootstrap (re-running
install.ps1 from inside Electron, the exact recursion Hermes-Setup.exe
was supposed to obviate).

Implementation:
  * New Stage-BootstrapMarker (worker) → Write-BootstrapMarker (helper)
  * Slotted in the manifest right after platform-sdks, before the
    interactive configure/gateway stages, so it runs unconditionally
    when the install reaches the finalize phase
  * Schema mirrors apps/desktop/electron/main.cjs writeBootstrapMarker /
    isBootstrapComplete EXACTLY: {schemaVersion: 1, pinnedCommit,
    pinnedBranch, completedAt}. Schema version stays at 1 so old
    desktops that read marker files written by future install.ps1s
    can still parse them.
  * pinnedCommit comes from -Commit flag (Hermes-Setup.exe passes it)
    or falls back to 'git rev-parse HEAD' in InstallDir
  * pinnedBranch from -Branch flag, defaults to 'main' matching
    install.ps1's own param default

Two PS-5.1 gotchas baked into comments:
  * The ?. null-conditional operator doesn't exist pre-PS7; use
    explicit if-checks on Get-Command results
  * Set-Content -Encoding UTF8 emits a BOM in 5.1 and Node's plain
    JSON.parse rejects BOM — write via .NET's UTF8Encoding(false)
    to produce BOM-less JSON the desktop's readJson() can parse

+## TypeScript Style
+
+Applies to TypeScript across Hermes: desktop, TUI, website, and future TS packages.
+
+- Prefer small nanostores over component state when state is shared, reused, or read by distant UI.
+- Let each feature own its atoms. Chat state belongs near chat, shell state near shell, shared state in `src/store`.
+- Components that render from an atom should use `useStore`. Non-rendering actions should read with `$atom.get()`.
+- Do not pass state through three components when the leaf can subscribe to the atom.
+- Keep persistence beside the atom that owns it.
+- Keep route roots thin. They compose routes and shell; they should not become controllers.
+- No monolithic hooks. A hook should own one narrow job.
+- Prefer colocated action modules over hidden god hooks.
+- If a callback is pure side effect, use the terse void form:
+  `onState={st => void setGatewayState(st)}`.
+- Async UI handlers should make intent explicit:
+  `onClick={() => void save()}`.
+- Prefer interfaces for public props and shared object shapes. Avoid `type X = { ... }` for object props.
+- Extend React primitives for props: `React.ComponentProps<'button'>`, `React.ComponentProps<typeof Dialog>`, `Omit<...>`, `Pick<...>`.
+- Table-driven beats condition ladders when mapping ids, routes, or views.
+- `src/app` owns routes, pages, and page-specific components.
+- `src/store` owns shared atoms.
+- `src/lib` owns shared pure helpers.

 - `/api/pty?token=…` upgrades to a WebSocket; auth uses the same ephemeral `_SESSION_TOKEN` as REST, via query param (browsers can't set `Authorization` on WS upgrade).
 - The server spawns whatever `hermes --tui` would spawn, through `ptyprocess` (POSIX PTY — WSL works, native Windows does not).

 ## ✨ Highlights
 
-- **xAI Grok via SuperGrok OAuth — and grok-4.3 jumps to a 1M context window** — If you pay for SuperGrok, you can now use Grok inside Hermes by signing in with your xAI account — no API key, no separate billing. The wire-through also bumps grok-4.3 to a 1M token context window, so you can drop whole codebases or research corpora into a single prompt. Includes proper handling for entitlement errors and an SSH-to-tunnel docs page for when you're SSH'd into a remote box and need to complete the OAuth flow. ([#26534](https://github.com/NousResearch/hermes-agent/pull/26534), [#26664](https://github.com/NousResearch/hermes-agent/pull/26664), [#26644](https://github.com/NousResearch/hermes-agent/pull/26644), [#26592](https://github.com/NousResearch/hermes-agent/pull/26592))
+- **Native Windows support (early beta)** — full PowerShell installer, native subprocess/PTY paths, taskkill-based process management, MinGit auto-install, Microsoft Store python stub detection, foreground Ctrl+C preservation, taskkill+ps2 fallback, npm prefix handling, and ~40 follow-up Windows-only fixes across CLI / gateway / TUI / curator / tools. Hermes finally runs natively on `cmd.exe` and PowerShell, no WSL required. ([#21561](https://github.com/NousResearch/hermes-agent/pull/21561), [#22130](https://github.com/NousResearch/hermes-agent/pull/22130), [#22752](https://github.com/NousResearch/hermes-agent/pull/22752), [#26618](https://github.com/NousResearch/hermes-agent/pull/26618), and many more)
 
-- **OpenAI-compatible local proxy for OAuth providers** — Run `hermes proxy` and you get a `http://localhost:port` endpoint that speaks the OpenAI API but is backed by whichever OAuth provider you're signed into — Claude Pro, ChatGPT Pro, SuperGrok. Now any tool that expects an OpenAI-compatible endpoint (Codex CLI, Aider, Cline, Continue, your custom scripts) just works with your existing subscription, no API key required. One subscription, every tool. ([#25969](https://github.com/NousResearch/hermes-agent/pull/25969))
+- **`pip install hermes-agent && hermes`** — Hermes Agent is now a real PyPI package. One command, no clone, no git, no shell installer. Wheel includes the Ink TUI bundle and shell launcher. (salvage of [#26350](https://github.com/NousResearch/hermes-agent/pull/26350)) ([#26593](https://github.com/NousResearch/hermes-agent/pull/26593))
 
-- **`x_search` — first-class X (Twitter) search tool** — The agent can now search X directly without installing a skill or wiring up a custom integration. Search the timeline, find threads, surface specific posts — straight from the chat. Auth with either your X OAuth login or an API key, whichever you have. ([#26763](https://github.com/NousResearch/hermes-agent/pull/26763))
+- **Cold-start performance wave — ~19s off `hermes` launch** — skills cache, lazy Feishu import, no Nous HTTP at startup, plus PEP-562 lazy adapter imports (QQ, Yuanbao, Teams, Google Chat), deferred `fal_client` / `google-cloud` / `httpx` loads, models.dev disk-cache-first lookup, parallel doctor API checks, eager-skip plugin discovery on built-in subcommands, `hermes tools` All-Platforms drops from 14s to <1.5s, welcome banner skipped on `chat -q`. ([#22138](https://github.com/NousResearch/hermes-agent/pull/22138), [#22120](https://github.com/NousResearch/hermes-agent/pull/22120), [#22681](https://github.com/NousResearch/hermes-agent/pull/22681), [#22790](https://github.com/NousResearch/hermes-agent/pull/22790), [#22808](https://github.com/NousResearch/hermes-agent/pull/22808), [#22831](https://github.com/NousResearch/hermes-agent/pull/22831), [#22859](https://github.com/NousResearch/hermes-agent/pull/22859), [#22904](https://github.com/NousResearch/hermes-agent/pull/22904), [#22766](https://github.com/NousResearch/hermes-agent/pull/22766), [#25341](https://github.com/NousResearch/hermes-agent/pull/25341))
 
-- **Microsoft Teams — end-to-end** — Hermes can now read messages from Teams and post back. The full Microsoft Graph stack lands together: auth + client foundation, a webhook listener that receives Teams events, a pipeline plugin runtime, and outbound delivery. Wire up the bot once, then chat to your agent from any Teams channel, DM, or group. (salvages of #21408–#21411) ([#21922](https://github.com/NousResearch/hermes-agent/pull/21922), [#21969](https://github.com/NousResearch/hermes-agent/pull/21969), [#22007](https://github.com/NousResearch/hermes-agent/pull/22007), [#22024](https://github.com/NousResearch/hermes-agent/pull/22024))
+- **180x faster `browser_console` evaluations** — routed through the supervisor's persistent CDP WebSocket instead of spawning a fresh DevTools session per call. Real-world page interactions feel instant. ([#23226](https://github.com/NousResearch/hermes-agent/pull/23226))
 
-- **Debloating wave — lighter installs, less you don't use** — A clean `pip install hermes-agent` used to pull down everything: every messaging adapter SDK, every image-gen SDK, every voice/TTS provider, whether you used them or not. Now those heavy backends (Slack / Matrix / Feishu / DingTalk adapters, hindsight client, codex app-server, Pixverse / Camofox / image-gen SDKs, voice/TTS providers) install automatically the first time you actually use them. The `[all]` extras drop everything covered by lazy-deps, the installer falls back through tiers when a wheel doesn't fit your platform, and a supply-chain advisory checker scans every install for unsafe versions. Faster installs, smaller disk footprint, fewer transitive vulnerabilities. ([#24220](https://github.com/NousResearch/hermes-agent/pull/24220), [#24515](https://github.com/NousResearch/hermes-agent/pull/24515), [#25014](https://github.com/NousResearch/hermes-agent/pull/25014), [#25038](https://github.com/NousResearch/hermes-agent/pull/25038), [#25766](https://github.com/NousResearch/hermes-agent/pull/25766), [#21818](https://github.com/NousResearch/hermes-agent/pull/21818))
+- **Supply-chain advisory checker + lazy-deps framework + tiered install fallback** — every `pip install` / `hermes update` scans dependencies against an advisory list, lazy-deps replace heavy import-time loads with first-use installs, and the installer falls back through extras tiers when a wheel rejects on the target platform. ([#24220](https://github.com/NousResearch/hermes-agent/pull/24220))
 
-- **`pip install hermes-agent && hermes`** — Hermes Agent is now a real PyPI package. No more cloning the repo or running shell installers — one pip command and you're running. The wheel ships with the Ink TUI bundle and the shell launcher, so the full experience comes out of the box. (salvage of [#26350](https://github.com/NousResearch/hermes-agent/pull/26350)) ([#26593](https://github.com/NousResearch/hermes-agent/pull/26593), [#26148](https://github.com/NousResearch/hermes-agent/pull/26148))
+- **OpenAI-compatible local proxy** — `hermes proxy` exposes any OAuth-authed provider (Claude Pro, ChatGPT Pro, SuperGrok) as an OpenAI-compatible endpoint that Codex / Aider / Cline / VS Code Continue can hit. Your subscription, your tools. ([#25969](https://github.com/NousResearch/hermes-agent/pull/25969))
 
-- **Cross-session 1h Claude prompt cache** — When you use Claude through Anthropic, OpenRouter, or Nous Portal, the prompt prefix (system prompt, skills, memory) now caches for an hour across sessions. Start a `/new` session and the first response comes back faster and cheaper because the cache is still warm from your last session. Background memory review hits the cache too, so it's not paying full price every turn. ([#23828](https://github.com/NousResearch/hermes-agent/pull/23828), [#25434](https://github.com/NousResearch/hermes-agent/pull/25434), [#24778](https://github.com/NousResearch/hermes-agent/pull/24778))
+- **Cross-session 1-hour Claude prompt cache** — Anthropic / OpenRouter / Nous Portal now share a 1h prefix cache across sessions for Claude models. Fast resume, fast `/new`, lower cost on repeat work. ([#23828](https://github.com/NousResearch/hermes-agent/pull/23828))
 
-- **180x faster `browser_console` evaluations** — When the agent uses the browser tool to inspect a page or run JavaScript, those calls now share one persistent connection to Chrome instead of spinning up a new DevTools session every time. The difference is huge: things that used to take a couple of seconds per call return in milliseconds. Real-world page interactions feel instant. ([#23226](https://github.com/NousResearch/hermes-agent/pull/23226))
+- **Two new messaging platforms — LINE + SimpleX Chat** — LINE Messaging API lands as a first-class platform, SimpleX Chat salvages #2558 onto the modern adapter spec. Hermes is now on 22 platforms. ([#23197](https://github.com/NousResearch/hermes-agent/pull/23197), [#26232](https://github.com/NousResearch/hermes-agent/pull/26232))
 
-- **Cold-start performance wave — ~19 seconds off `hermes` launch** — Running `hermes` used to make you wait through a chunk of import overhead and network calls before you saw a prompt. Now the launch path is mostly deferred: heavy adapters only load when you use them, model catalogs come from disk cache first, doctor checks run in parallel, and `chat -q` skips the welcome banner entirely. The `hermes tools` All-Platforms screen alone dropped from 14 seconds to under 1.5 seconds. ([#22138](https://github.com/NousResearch/hermes-agent/pull/22138), [#22120](https://github.com/NousResearch/hermes-agent/pull/22120), [#22681](https://github.com/NousResearch/hermes-agent/pull/22681), [#22790](https://github.com/NousResearch/hermes-agent/pull/22790), [#22808](https://github.com/NousResearch/hermes-agent/pull/22808), [#22831](https://github.com/NousResearch/hermes-agent/pull/22831), [#22859](https://github.com/NousResearch/hermes-agent/pull/22859), [#22904](https://github.com/NousResearch/hermes-agent/pull/22904), [#22766](https://github.com/NousResearch/hermes-agent/pull/22766), [#25341](https://github.com/NousResearch/hermes-agent/pull/25341))
+- **Microsoft Graph foundation — Teams pipeline + webhook adapter** — `msgraph` auth/client foundation, webhook listener platform, Teams pipeline plugin runtime, and Teams outbound delivery via the existing adapter — Hermes can now read and post to Teams. (salvages of #21408–#21411) ([#21922](https://github.com/NousResearch/hermes-agent/pull/21922), [#21969](https://github.com/NousResearch/hermes-agent/pull/21969), [#22007](https://github.com/NousResearch/hermes-agent/pull/22007), [#22024](https://github.com/NousResearch/hermes-agent/pull/22024))
 
-- **Two new messaging platforms — LINE + SimpleX Chat** — LINE is huge in Japan, Korea, and Taiwan, and now Hermes runs natively on the LINE Messaging API. SimpleX Chat is the privacy-focused decentralized messenger with no user IDs — also wired up as a first-class platform. That brings Hermes to 22 messaging platforms total, so wherever you and your team chat, the agent can be there. ([#23197](https://github.com/NousResearch/hermes-agent/pull/23197), [#26232](https://github.com/NousResearch/hermes-agent/pull/26232))
+- **`/handoff` actually transfers the session live** — the agent's active session moves to a different model / persona / profile mid-conversation, with messages, tool history, and context preserved. ([#23395](https://github.com/NousResearch/hermes-agent/pull/23395))
 
-- **`/handoff` actually transfers the session live** — Switching models or personalities mid-conversation used to mean losing context or starting over. Now `/handoff` moves your active session — every message, every tool call, every piece of context — to the target model, persona, or profile, live, without dropping anything. Mid-debugging hand off from a fast model to a deep-reasoning one, or pass a session between profiles for different parts of a task. ([#23395](https://github.com/NousResearch/hermes-agent/pull/23395))
+- **`x_search` — first-class X (Twitter) search tool** — gated tool with OAuth-or-API-key auth, no skill needed to query the timeline. ([#26763](https://github.com/NousResearch/hermes-agent/pull/26763))
 
-- **Native button UI for `clarify` on Telegram and Discord** — When the agent uses the `clarify` tool to ask you a multiple-choice question, it now shows real platform-native buttons on Telegram and Discord instead of asking you to type back the option number. Tap the button, the agent gets your answer. Especially nice on mobile. ([#24199](https://github.com/NousResearch/hermes-agent/pull/24199), [#25485](https://github.com/NousResearch/hermes-agent/pull/25485))
+- **`vision_analyze` returns pixels to vision-capable models** — when the active model can see, `vision_analyze` now hands the image straight through instead of falling back to a text description. ([#22955](https://github.com/NousResearch/hermes-agent/pull/22955))
 
-- **Discord channel history backfill (default on)** — When Hermes joins a Discord channel or thread for the first time, it now reads the recent message history so it knows what's been said before it responds. No more "what are we talking about?" — the agent has the context that's already on screen for everyone else. ([#25984](https://github.com/NousResearch/hermes-agent/pull/25984))
+- **LSP semantic diagnostics on every write** — `write_file` and `patch` now run real language-server diagnostics on the post-edit file (delta-only) and surface real errors before they ship downstream. ([#24168](https://github.com/NousResearch/hermes-agent/pull/24168), [#25978](https://github.com/NousResearch/hermes-agent/pull/25978))
 
-- **`vision_analyze` returns pixels to vision-capable models** — When you point the agent at an image with `vision_analyze` and the active model can actually see (GPT-5, Claude, Gemini, Grok-vision), Hermes now passes the raw pixels straight to the model instead of converting them to a text description first. You get the model's actual visual reasoning instead of a degraded text-summary round-trip. ([#22955](https://github.com/NousResearch/hermes-agent/pull/22955))
+- **Per-turn file-mutation verifier footer** — after every turn that wrote files, the agent gets a verifier footer summarizing what actually changed on disk — catches silent overwrites and "wrote it but it didn't land" bugs. ([#24498](https://github.com/NousResearch/hermes-agent/pull/24498))
 
-- **Per-turn file-mutation verifier footer** — After every turn that wrote or edited files, the agent now gets a short footer summarizing exactly what changed on disk — the file paths, the line counts, the actual delta. That means the agent catches its own mistakes when a write didn't land or got silently overwritten, instead of confidently telling you "I added the function" when the file wasn't actually saved. ([#24498](https://github.com/NousResearch/hermes-agent/pull/24498))
+- **Unified `video_generate` with pluggable provider backends** — single tool, any backend. Drop in a new video provider as a plugin, no core changes. ([#25126](https://github.com/NousResearch/hermes-agent/pull/25126))
 
-- **LSP semantic diagnostics on every write** — When the agent uses `write_file` or `patch`, Hermes now runs a real language server against the edited file and surfaces any new errors back to the agent before the next turn. Type errors, undefined symbols, missing imports — caught immediately. Goes way beyond v0.13.0's basic Python/JSON/YAML/TOML linting because it's actual semantic analysis. ([#24168](https://github.com/NousResearch/hermes-agent/pull/24168), [#25978](https://github.com/NousResearch/hermes-agent/pull/25978))
+- **`computer_use` cua-driver backend** — proper focus-safe ops, non-Anthropic provider support, refresh on `hermes update`. Computer-use is no longer locked to a single SDK. (re-salvage of #16936) ([#21967](https://github.com/NousResearch/hermes-agent/pull/21967), [#24063](https://github.com/NousResearch/hermes-agent/pull/24063))
 
-- **Unified `video_generate` with pluggable provider backends** — One tool, any video model. Hermes ships with the obvious backends already, but you can drop in a new video provider as a plugin without touching core. So when a new video model lands next month, it can be a one-file plugin instead of a fork. ([#25126](https://github.com/NousResearch/hermes-agent/pull/25126))
+- **xAI Grok OAuth provider — SuperGrok via subscription** — sign in with your xAI account, talk to Grok models from Hermes. ([#26534](https://github.com/NousResearch/hermes-agent/pull/26534))
 
-- **`computer_use` cua-driver backend — works with non-Anthropic models now** — Computer-use (the agent controlling your mouse and keyboard to drive GUI apps) used to be locked to Anthropic's SDK. The new cua-driver backend works with non-Anthropic providers too, has proper focus-safe operations, and refreshes itself on `hermes update`. Now any vision-capable model can drive your desktop. (re-salvage of #16936) ([#21967](https://github.com/NousResearch/hermes-agent/pull/21967), [#24063](https://github.com/NousResearch/hermes-agent/pull/24063))
+- **Clarify with buttons — native inline keyboards on Telegram + Discord** — the `clarify` tool renders multi-choice prompts as platform-native buttons instead of typed responses. ([#24199](https://github.com/NousResearch/hermes-agent/pull/24199), [#25485](https://github.com/NousResearch/hermes-agent/pull/25485))
 
-- **Clickable URLs in any terminal** — Links in agent output are now real OSC8 hyperlinks with hover-highlight in any terminal that supports them. Click to open in your browser — no more copy-paste-trim of long URLs from the transcript. Just works in iTerm2, Kitty, Ghostty, modern Windows Terminal, etc. (@OutThisLife) ([#25071](https://github.com/NousResearch/hermes-agent/pull/25071), [#24013](https://github.com/NousResearch/hermes-agent/pull/24013))
+- **Discord channel history backfill (default on)** — Hermes reads recent channel history when joining a thread so it actually knows what's been said. ([#25984](https://github.com/NousResearch/hermes-agent/pull/25984))
 
-- **Zed ACP Registry — `uvx` install in one click** — Hermes is now listed in Zed's Agent Client Protocol registry, so Zed users can install it with one click. The install path uses `uvx` so there's no npm dependency. `hermes acp --setup-browser` bootstraps the browser tools for registry-driven installs. (salvage of [#25908](https://github.com/NousResearch/hermes-agent/pull/25908)) ([#26079](https://github.com/NousResearch/hermes-agent/pull/26079), [#26120](https://github.com/NousResearch/hermes-agent/pull/26120), [#26234](https://github.com/NousResearch/hermes-agent/pull/26234))
+- **Watchers skill — RSS / HTTP JSON / GitHub polling via cron `no_agent` mode** — skill recipes that wire change-detection sources directly into cron's script-only watchdog mode. ([#21881](https://github.com/NousResearch/hermes-agent/pull/21881))
 
-- **OpenRouter Pareto Code router with `min_coding_score` knob** — OpenRouter's "Pareto" router automatically picks the cheapest model that meets a minimum quality bar. The new `min_coding_score` config lets you set that bar for coding tasks specifically — Hermes routes to the most affordable model that's at least that good at code. Stop paying for top-tier models when a mid-tier one would do. ([#22838](https://github.com/NousResearch/hermes-agent/pull/22838))
+- **Zed ACP Registry integration + uvx distribution** — Hermes is in the Zed registry, installable via `uvx` (no npm). Plus `hermes acp --setup-browser` bootstraps browser tools for registry installs. (salvage of [#25908](https://github.com/NousResearch/hermes-agent/pull/25908)) ([#26079](https://github.com/NousResearch/hermes-agent/pull/26079), [#26120](https://github.com/NousResearch/hermes-agent/pull/26120), [#26234](https://github.com/NousResearch/hermes-agent/pull/26234))
 
-- **NovitaAI as a new model provider** — NovitaAI joins the provider lineup, giving you another option for open-source model hosting (Llama, Qwen, DeepSeek, etc.) with their pricing and rate limits. (salvage #7219) (@kshitijk4poor) ([#25507](https://github.com/NousResearch/hermes-agent/pull/25507))

-- **Codex app-server runtime for OpenAI/Codex models** — An optional runtime that drives OpenAI's Codex CLI under the hood when you're using OpenAI or Codex paths. You get session reuse, automatic retirement of wedged sessions, and proper OAuth refresh classification — the kind of plumbing that makes long agentic runs not fall over. ([#24182](https://github.com/NousResearch/hermes-agent/pull/24182), [#25769](https://github.com/NousResearch/hermes-agent/pull/25769))

([#24182](https://github.com/NousResearch/hermes-agent/pull/24182), [#25769](https://github.com/NousResearch/hermes-agent/pull/25769))
 
-- **`huggingface/skills` as a trusted default tap** — The community skills index hosted at huggingface.co/skills is now wired into the Skills Hub by default. So when somebody publishes a useful skill there, you can install it from your own `hermes skills` browser without any extra config. (closes #2549) ([#26219](https://github.com/NousResearch/hermes-agent/pull/26219))

-- **API server exposes run approval events** — If you're driving Hermes programmatically through the HTTP API, long-running runs no longer silently hang when the agent hits an approval-required command. The approval request now surfaces on the API stream so your client can prompt the user and reply — no more silent stalls. (salvage of [#20311](https://github.com/NousResearch/hermes-agent/pull/20311)) ([#21899](https://github.com/NousResearch/hermes-agent/pull/21899))

-- **Plugins can run any LLM call via `ctx.llm` + replace built-in tools via `tool_override`** — If you're writing a Hermes plugin, you now get first-class access to make LLM calls through the active provider and credentials — no manual client wiring. The new `tool_override` flag lets a plugin swap out a built-in tool with its own implementation cleanly. Plugin authors get the same model-routing and auth plumbing the core agent uses. (closes #11049) ([#23194](https://github.com/NousResearch/hermes-agent/pull/23194), [#26759](https://github.com/NousResearch/hermes-agent/pull/26759))
+- **`/subgoal` — user-added criteria appended to active `/goal`** — layer extra success criteria onto a running goal loop. The judge sees them in the prompt, no behavior change when subgoals are empty. ([#25449](https://github.com/NousResearch/hermes-agent/pull/25449))
 
-- **Brave Search (free tier) + DuckDuckGo (DDGS) as web-search providers** — Two new free web-search backends join Tavily, SearXNG, and Exa. Brave Search has a generous free tier; DDGS is the DuckDuckGo scraper that needs no key at all. Pick whichever fits your budget and rate-limit needs. ([#21337](https://github.com/NousResearch/hermes-agent/pull/21337))
+- **Plugins can run any LLM call via `ctx.llm`** — plugins get a first-class hook to make their own LLM requests through the active provider/credentials, no manual wiring. Plus `tool_override` flag for replacing built-in tools. ([#23194](https://github.com/NousResearch/hermes-agent/pull/23194), [#26759](https://github.com/NousResearch/hermes-agent/pull/26759))
 
-- **Sudo brute-force block + 3 dangerous-command bypasses closed + tool-error sanitization** — The approval gate now blocks `sudo -S` brute-force attempts and classifies stdin-fed or askpass-stripped sudo invocations as DANGEROUS. Three known bypasses of dangerous-command detection are closed (inspired by Claude Code's command-detection work). And tool error strings are now sanitized before being re-injected into the model context, so a malicious file or remote service can't pass instructions to your agent through error output.

-- **`/subgoal` — user-added criteria appended to an active `/goal`** — When you've got a `/goal` running (the persistent Ralph-loop goal where the agent keeps going until criteria are met), you can now use `/subgoal <text>` to layer extra success criteria onto it mid-run. The judge factors your new criteria into the done-or-keep-going decision without restarting the loop. ([#25449](https://github.com/NousResearch/hermes-agent/pull/25449))
+- **Sudo brute-force block + sudo-stdin/askpass DANGEROUS classification** — closes the `sudo -S` brute-force avenue; approval gates classify stdin-fed and askpass-stripped sudo invocations as dangerous. (salvages of #22194 + #21128) ([#23736](https://github.com/NousResearch/hermes-agent/pull/23736))
 
-- **Provider rename — Alibaba Cloud → Qwen Cloud** — The Alibaba Cloud provider is renamed to Qwen Cloud in the picker and config to match what the rest of the world calls it. Existing config keys still work — no breaking changes — but the UI matches the actual brand now. ([#24835](https://github.com/NousResearch/hermes-agent/pull/24835))

-- **Native Windows support (early beta)** — Hermes now runs natively on `cmd.exe` and PowerShell without WSL. A full PowerShell installer handles MinGit auto-install, Microsoft Store python stub detection, and the foreground Ctrl+C dance. There's still rough edges (this is the "early beta" stamp) — ~40 follow-up Windows-only fixes already landed in the window — but the basic loop works end-to-end on a clean Windows box. ([#21561](https://github.com/NousResearch/hermes-agent/pull/21561))

+
+    The returned object is a ``SimpleNamespace`` shaped like the SDK's typed
+    ``Response`` for the fields downstream code actually reads:
+
+    * ``output``: list of output items, assembled from ``response.output_item.done``.
+      For tool-call turns this contains the function_call items; for plain-text
+      turns it contains a synthesized ``message`` item built from streamed deltas
+      if no message item was emitted directly.
+    * ``output_text``: assembled text from ``response.output_text.delta`` deltas.
+    * ``usage``: copied from the terminal event's ``response.usage`` (when present).
+    * ``status``: ``completed`` / ``incomplete`` / ``failed`` (or ``completed`` if
+      the stream ended without a terminal frame but produced content).
+    * ``id``: ``response.id`` when present.
+    * ``incomplete_details``: passed through for ``response.incomplete`` frames.
+    * ``error``: passed through for ``response.failed`` frames.
+    * ``model``: from kwargs (the wire model name is not authoritative).
+
+    Critically, we never read ``response.output`` from the terminal event for
+    content reconstruction — only ``usage``, ``status``, ``id``.  That field
+    being ``null`` / ``[]`` / missing is fine.
+
+    Callbacks:
+
+    * ``on_text_delta(str)`` — fires per ``response.output_text.delta``, suppressed
+      once a function_call event is seen (so tool-call turns don't bleed text
+      into the chat).
+    * ``on_reasoning_delta(str)`` — fires per ``response.reasoning.*.delta``.
+    * ``on_first_delta()`` — one-shot, fires on the first text delta only.
+    * ``on_event(event)`` — fires for every event before any other processing.
+      Used for watchdog activity, debug logging, anything wire-shape-agnostic.
+    * ``interrupt_check()`` — returns True to break the loop early.

+Transcription Provider ABC
+==========================
+
+Defines the pluggable-backend interface for speech-to-text. Providers
+register instances via
+:meth:`PluginContext.register_transcription_provider`; the active one
+(selected via ``stt.provider`` in ``config.yaml``) services every
+:func:`tools.transcription_tools.transcribe_audio` call **when the
+configured name is neither a built-in (``local``, ``local_command``,
+``groq``, ``openai``, ``mistral``, ``xai``) nor disabled**.
+
+Two coexisting STT extension surfaces — in resolution order:
+
+1. **Built-in providers** (``BUILTIN_STT_PROVIDERS`` in
+   :mod:`tools.transcription_tools`) — native Python implementations
+   for the 6 backends shipped today (faster-whisper, local_command,
+   Groq, OpenAI, Mistral, xAI). **Always win** — plugins cannot
+   shadow them. The single-env-var shell escape hatch
+   ``HERMES_LOCAL_STT_COMMAND`` is preserved via the built-in
+   ``local_command`` path.
+2. **Plugin-registered providers** (this ABC). For new STT backends —
+   OpenRouter, SenseAudio, Gemini-STT, custom proprietary engines —
+   that need a Python implementation without modifying
+   ``tools/transcription_tools.py``.
+
+Built-ins-always-win is enforced at registration time
+(:func:`agent.transcription_registry.register_provider` rejects names
+in ``BUILTIN_STT_PROVIDERS`` with a warning) AND at dispatch time
+(:func:`tools.transcription_tools._dispatch_to_plugin_provider`

+Text-to-Speech Provider ABC
+============================
+
+Defines the pluggable-backend interface for text-to-speech synthesis.
+Providers register instances via
+``PluginContext.register_tts_provider()``; the active one (selected via
+``tts.provider`` in ``config.yaml``) services every ``text_to_speech``
+tool call **only when the configured name is neither a built-in nor a
+command-type provider declared under ``tts.providers.<name>``**.
+
+Three coexisting TTS extension surfaces — in resolution order:
+
+1. **Built-in providers** (``BUILTIN_TTS_PROVIDERS`` in
+   :mod:`tools.tts_tool`) — native Python implementations (edge, openai,
+   elevenlabs, …). **Always win** — plugins cannot shadow them.
+2. **Command-type providers** declared under ``tts.providers.<name>:
+   type: command`` (PR #17843, commit ``2facea7f7``). Wire any local
+   CLI into Hermes with shell-template placeholders. **Wins over a
+   same-name plugin** — config is more local than plugin install.
+3. **Plugin-registered providers** (this ABC). For backends that need a
+   Python SDK, streaming bytes, OAuth refresh, or voice-listing APIs
+   the shell-template grammar can't reasonably express.
+
+Built-ins-always-win is enforced at registration time
+(:func:`agent.tts_registry.register_provider` rejects names in
+``BUILTIN_TTS_PROVIDERS`` with a warning) AND at dispatch time
+(:func:`tools.tts_tool._dispatch_to_plugin_provider` re-checks
+defensively). The dispatcher also rejects plugin dispatch when a same-
+name command provider is configured.
+
+Providers live in ``<repo>/plugins/tts/<name>/`` (built-in plugins, no
+shipped today) or ``~/.hermes/plugins/tts/<name>/`` (user-installed).
+None ship in-tree as of issue #30398 — the hook is additive
+infrastructure waiting for a real consumer (Cartesia, Fish Audio, …).

+Response contract

+:meth:`TTSProvider.synthesize` writes the audio bytes to ``output_path``
+and returns the path as a string. Implementations should raise on
+failure — the dispatcher converts exceptions into the standard
+``{success: False, error: …}`` JSON envelope the rest of Hermes
+expects.

+    Hermes Setup application manifest.
+
+    The TL;DR: tell Windows we are NOT an installer in the classic "needs
+    UAC elevation" sense, despite the product name. We provision into
+    %LOCALAPPDATA%\hermes which is user-scoped and never touch HKLM or
+    Program Files. install.ps1 runs as a child process and elevates
+    itself only if a future stage explicitly needs HKLM access.
+
+    Without this manifest, the "Hermes Setup" productName embedded in
+    the binary's resource trips Windows's installer-detection heuristic
+    (https://learn.microsoft.com/en-us/windows/security/identity-protection/
+    user-account-control/how-user-account-control-works#installer-detection)
+    and CreateProcess fails with ERROR_ELEVATION_REQUIRED (740) when the
+    user double-clicks. asInvoker disables that.

+ * Hermes Setup — defer entirely to the desktop's styles.css.
+ *
+ * Rather than re-implement the Hermes design system (and inevitably drift
+ * from it), we import apps/desktop/src/styles.css wholesale. The desktop
+ * is the canonical source of truth for fonts, color tokens, button chrome,
+ * scrollbars, layout utilities, and animations. Any change to the
+ * Hermes look propagates here automatically with no copy-paste maintenance.
+ *
+ * Path resolution caveats:
+ *   - Tailwind v4's `@import` resolves relative to this file. The desktop's
+ *     `@source '../../../node_modules/...'` declarations therefore re-resolve
+ *     against apps/bootstrap-installer/src/. Since both apps live two levels
+ *     deep under the same repo root, `../../../node_modules` lands in the
+ *     same place. (Verify if either app ever moves.)
+ *   - The desktop's `@font-face url('../../../node_modules/...')` references
+ *     are baked into the *imported* stylesheet; CSS resolves url()s relative
+ *     to the file that contains them, so they continue to point at the
+ *     correct node_modules path even from here.
+ *
+ * Forced light mode: the desktop ships with a runtime theme switcher
+ * (ThemeProvider + applyTheme) that can flip to dark via document.documentElement.
+ * The installer has no UI for theme switching, so we stay on the desktop's
+ * default light surface (Nous-blue accent on near-white chrome).
