feat(lint): observability for the LSP bridge with steady-state silence

Adds per-call structured logging on the dedicated ``hermes.lint.lsp``
logger so an opt-in user can answer "did LSP fire on that edit?" with
``rg 'lsp\['`` against ``~/.hermes/logs/agent.log``. Levels are tuned
so a 1000-write session emits exactly ONE INFO line at the default
threshold, not 1000.

Level model
-----------
* ``DEBUG`` (invisible at the default INFO threshold) for every per-call
  steady-state event: ``clean``, ``feature off``, ``extension not
  mapped``, ``backend not local``, repeated ``no project root`` for an
  already-announced file, repeated ``server unavailable`` for an
  already-announced binary.
* ``INFO`` for state transitions worth surfacing once: ``active for
  <root>`` the first time a (language, project_root) client starts,
  ``no project root for <path>`` the first time we see that orphan
  file. Plus every ``N diags`` event — diagnostics are inherently rare
  per-edit and are exactly the failure signal users want to grep for.
* ``WARNING`` for action-required failures the first time per
  (language, binary): ``server unavailable`` (binary not on PATH),
  ``no server configured``. Per-call ``WARNING`` for timeouts, server
  errors, and unexpected bridge exceptions — these are inherently
  novel events, not steady state, and each one is its own signal.

Dedup is in-process module-level sets guarded by a lock. Sets grow at
most by the number of distinct (language, project_root) and (language,
binary) pairs touched in one Python process — a few hundred entries in
the most aggressive monorepo session, which is bytes of memory. A
bounded LRU was rejected because evicting an entry would risk
re-firing the WARNING/INFO line we explicitly want to suppress.

Why this matters
----------------
The previous draft logged every per-call event at INFO. ``agent.log``
caps at 5 MB × 3 backups (= 20 MB) via ``RotatingFileHandler``, so
nothing would crash, but a normal coding session would dwarf the actual
signal under hundreds of ``lsp[typescript] clean (...)`` lines. The
new model preserves the verification answer ("LSP active for <root>")
and the action-required signals while keeping clean steady state out
of the user's face.

Tests
-----
* ``TestLogLevelsSteadyState`` — feature off, unmapped extension, non-
  local backend, and repeated clean writes all stay at DEBUG. Exactly
  one INFO ("active for ...") survives across N calls.
* ``TestLogLevelsNovelEvents`` — diagnostics are INFO per call;
  ``active for`` fires once per (language, root).
* ``TestLogLevelsActionRequired`` — server unavailable warns once per
  binary; orphan files INFO once per path; timeouts WARN every time.

-- 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.

-## Dependency Pinning Policy
-
-All dependencies must have upper bounds to limit supply-chain attack surface.
-This policy was established after the litellm compromise (PR #2796, #2810) and
-reinforced after the Mini Shai-Hulud worm campaign (May 2026).
-
-| Source type | Treatment | Example |
-|---|---|---|
-| PyPI package | `>=floor,<next_major` | `"httpx>=0.28.1,<1"` |
-| Git URL | Commit SHA | `git+https://...@<40-char-sha>` |
-| GitHub Actions | Commit SHA + comment | `uses: actions/checkout@<sha>  # v4` |
-| CI-only pip | `==exact` | `pyyaml==6.0.2` |
-
-**When adding a new dependency to `pyproject.toml`:**
-1. Pin to `>=current_version,<next_major` for post-1.0 (e.g. `>=1.5.0,<2`).
-2. For pre-1.0 packages, use `<0.(current_minor + 2)` (e.g. `>=0.29,<0.32`).
-3. Never commit a bare `>=X.Y.Z` without a ceiling — CI and reviewers will reject it.
-4. Run `uv lock` to regenerate `uv.lock` with hashes.

-- Per-test overhead is ~0.5–1.0s (Python startup + pytest collection). xdist
-  parallelism amortizes this across cores; on a 20-core box the full suite
-  finishes in roughly the same wall time as before, but flake-free.
-- `isolate_timeout` (configured in `pyproject.toml`) caps each test at 30s.
-  Hangs are killed and surfaced as a failure report.
-- Pass `--no-isolate` to disable isolation — useful when debugging a single
-  test interactively, or when you specifically want to verify state leakage.
-- The plugin disables itself in child processes (sentinel envvar
-  `HERMES_ISOLATE_CHILD=1`), so there's no fork-bomb risk.

-- Integrate with `hermes memory setup` via `post_setup()` — no need to touch core code
-- Can register their own CLI subcommands via `register_cli(subparser)` in a `cli.py` file
-- Get all the same lifecycle hooks and config plumbing as in-tree providers
-
-PRs that add a new directory under `plugins/memory/` will be closed with a pointer to publish the provider as its own repo. Existing in-tree providers stay; bug fixes to them are welcome.

-### Skill authoring standards (HARDLINE)
-
-Every new or modernized skill — bundled, optional, or contributed — must meet these standards before merge. Reviewers reject PRs that violate them.
-
-1. **`description` ≤ 60 characters, one sentence, ends with a period.** Long descriptions bloat the skill listing UI and dilute the model's attention when many skills are loaded. State the capability, not the implementation. No marketing words ("powerful", "comprehensive", "seamless", "advanced"). Don't repeat the skill name. Verify with:
-   ```python
-   import re, pathlib
-   m = re.search(r'^description: (.*)$',
-                 pathlib.Path('skills/<cat>/<name>/SKILL.md').read_text(),
-                 re.MULTILINE)
-   assert len(m.group(1)) <= 60, len(m.group(1))
-   ```
-
-   Good: `Search arXiv papers by keyword, author, category, or ID.`
-   Bad: `A powerful and comprehensive skill that allows the agent to search arXiv for relevant academic papers using various criteria including keywords, authors, and categories.`
-
-2. **Tools referenced in SKILL.md prose must be native Hermes tools or MCP servers the skill explicitly expects.** When the skill needs a capability, point at the proper tool by name in backticks: `` `terminal` ``, `` `web_extract` ``, `` `web_search` ``, `` `read_file` ``, `` `write_file` ``, `` `patch` ``, `` `search_files` ``, `` `vision_analyze` ``, `` `browser_navigate` ``, `` `delegate_task` ``, `` `image_generate` ``, `` `text_to_speech` ``, `` `cronjob` ``, `` `memory` ``, `` `skill_view` ``, `` `todo` ``, `` `execute_code` ``.
-
-   Do NOT name shell utilities the agent already has wrapped:
-
-   | Don't say | Say |
-   |---|---|
-   | `grep`, `rg` | `search_files` |
-   | `cat`, `head`, `tail` | `read_file` |
-   | `sed`, `awk` | `patch` |
-   | `find`, `ls` | `search_files` (with `target='files'`) |
-   | `curl` for content extraction | `web_extract` |
-   | `echo > file`, `cat <<EOF` | `write_file` |
-
-   If the skill depends on an MCP server, name the MCP server and document its setup in `## Prerequisites`. Third-party CLIs (e.g. `ffmpeg`, `gh`, a specific SDK) are fine to invoke from inside script files, but the prose should frame the interaction as "invoke through the `terminal` tool", not as a manual shell session.
-
-3. **`platforms:` gating audited against actual script imports.** Skills that use POSIX-only primitives (`fcntl`, `termios`, `os.setsid`, `os.kill(pid, 0)` for liveness, `/proc`, hardcoded `/tmp` paths, `signal.SIGKILL`, bash heredocs, `osascript`, `apt`, `systemctl`) must declare their supported platforms via the `platforms:` frontmatter. Default posture is to fix it cross-platform first — `tempfile.gettempdir()`, `pathlib.Path`, `psutil.pid_exists()`, Python-level filtering instead of `grep`. Gate to a narrower set only when the dependency is genuinely platform-bound (e.g. `osascript` is macOS-only, `/proc` is Linux-only).
-
-4. **`author` credits the human contributor first.** For external contributions, the contributor's real name + GitHub handle goes first (`Jane Doe (jane-doe)`); "Hermes Agent" is the secondary collaborator. If the contributor's commit shows "Hermes Agent" as author because they used Hermes to draft the skill, replace it with their actual name — credit the human, not the tool.
-
-5. **SKILL.md body uses the modern section order.** `# <Skill> Skill` title, 2-3 sentence intro stating what it does and what it doesn't do, then:
-   - `## When to Use` — trigger conditions
-   - `## Prerequisites` — env vars, install steps, MCP setup, API key sourcing
-   - `## How to Run` — canonical invocation through the `terminal` tool
-   - `## Quick Reference` — flat command/API reference
-   - `## Procedure` — numbered steps with copy-paste commands
-   - `## Pitfalls` — known limits, rate limits, things that look broken but aren't
-   - `## Verification` — single command that proves the skill works
-
-   Target ~200 lines for a complex skill, ~100 lines for a simple one. Cut redundant intro fluff, marketing prose, and re-explanations of env vars already documented in `## Prerequisites`.
-
-6. **Scripts go in `scripts/`, references in `references/`, templates in `templates/`.** Don't expect the model to inline-write parsers, XML walkers, or non-trivial logic every call — ship a helper script. Reference scripts from SKILL.md by path relative to the skill directory.
-
-7. **Tests live at `tests/skills/test_<skill>_skill.py`** and use only stdlib + pytest + `unittest.mock`. No live network calls. Run via `scripts/run_tests.sh tests/skills/test_<skill>_skill.py -q`. Must pass under the hermetic CI env (no API keys leaking through). Use `monkeypatch` and `tmp_path` for any env-var or filesystem dependencies.
-
-8. **`.env.example` additions are isolated to a clearly delimited block.** Don't touch the surrounding file — contributor-supplied `.env.example` versions are usually stale, and edits outside the skill's own block will be dropped during salvage. Comment all values with `#` (it's documentation, not live config).

-### Dependency pinning policy (supply chain hardening)
-
-After the [litellm supply chain compromise](https://github.com/BerriAI/litellm/issues/24512) in March 2026 and the [Mini Shai-Hulud worm campaign](https://socket.dev/blog/tanstack-npm-packages-compromised-mini-shai-hulud-supply-chain-attack) in May 2026, all dependencies must follow these rules:
-
-| Source type | Required treatment | Rationale |
-|---|---|---|
-| **PyPI package** | `>=floor,<next_major` | PyPI versions are immutable once published, but new versions can be pushed into your range. A `<next_major` ceiling stops a 1.x install from upgrading to a malicious 2.0.0. |
-| **Git URL** (atroposlib, tinker, yc-bench, Baileys) | Full commit SHA | Branches and tags are mutable refs; SHA is content-addressed. |
-| **GitHub Actions** | Full commit SHA + version comment | Action tags are mutable refs (e.g. tj-actions/changed-files March 2025). Pin as `uses: owner/action@<sha>  # vX.Y.Z` |
-| **CI-only pip installs** | `==exact` | Hermetic CI builds; churn is acceptable. |
-
-**Every new PyPI dependency in a PR must have a `<next_major` upper bound.** PRs adding unbounded `>=X.Y.Z` specs will be rejected by reviewers. The `supply-chain-audit.yml` CI workflow also flags dependency manifest changes for manual review.
-
-**How to determine the ceiling:**
-- If the package is at version `1.x.y`, use `<2`.
-- If the package is at version `0.x.y` (pre-1.0), use `<0.(current_minor + 2)` — e.g. if current is `0.29.x`, use `<0.32`. This gives ~2 minor versions of headroom while keeping the window small enough that a hostile takeover version is unlikely to land inside it.
-- Exception: packages with very stable APIs (e.g. `aiohttp-socks`) can use `<1` at reviewer discretion.
-
-**Examples:**
-```toml
-# ✅ Correct — post-1.0
-"openai>=2.21.0,<3"
-"pydantic>=2.12.5,<3"
-
-# ✅ Correct — pre-1.0 (tight minor window)
-"asyncpg>=0.29,<0.32"
-"aiosqlite>=0.20,<0.23"
-"hindsight-client>=0.4.22,<0.5"
-
-# ❌ Rejected — no upper bound
-"some-package>=1.2.3"
-
-# ❌ Rejected — too tight (blocks legitimate patches)
-"some-package==1.2.3"
-
-# ❌ Rejected — too loose for pre-1.0 (allows 80 minor versions)
-"some-package>=0.20,<1"
-```

-## Skip the API-key collection — Nous Portal
-
-Hermes works with whatever provider you want — that's not changing. But if you'd rather not collect five separate API keys for the model, web search, image generation, TTS, and a cloud browser, **[Nous Portal](https://portal.nousresearch.com)** covers all of them under one subscription:
-
-- **300+ models** — pick any of them with `/model <name>`
-- **Tool Gateway** — web search (Firecrawl), image generation (FAL), text-to-speech (OpenAI), cloud browser (Browser Use), all routed through your sub. No extra accounts.
-
-One command from a fresh install:
-
-```bash
-hermes setup --portal
-```
-
-That logs you in via OAuth, sets Nous as your provider, and turns on the Tool Gateway. Check what's wired up any time with `hermes portal status`. Full details on the [Tool Gateway docs page](https://hermes-agent.nousresearch.com/docs/user-guide/features/tool-gateway).

-You can still bring your own keys per-tool whenever you want — the gateway is per-backend, not all-or-nothing.

-
-Hermes 始终允许你使用任意服务商，这点不会改变。但如果你不想为模型、网页搜索、图像生成、TTS、云浏览器分别去申请五个不同的 API Key，**[Nous Portal](https://portal.nousresearch.com)** 用一个订阅就能覆盖全部：

-- **Tool Gateway** — 网页搜索（Firecrawl）、图像生成（FAL）、文本转语音（OpenAI）、云浏览器（Browser Use），全部通过订阅托管。无需额外注册任何账户。
-
-全新安装时一条命令即可：
-
-```bash
-hermes setup --portal
-```
-
-它会通过 OAuth 登录、把 Nous 设为推理服务商，并启用 Tool Gateway。随时用 `hermes portal status` 查看路由状态。完整说明见 [Tool Gateway 文档](https://hermes-agent.nousresearch.com/docs/user-guide/features/tool-gateway)。

-> The Foundation Release — Hermes Agent installs and runs anywhere now. Native Windows ships in early beta with a full PowerShell installer story, a `pip install hermes-agent` wheel lands on PyPI, lazy-deps reshape what `pip install hermes-agent` actually pulls down, the supply-chain checker scans every install/upgrade for unsafe versions, and a new OpenAI-compatible local proxy lets Codex / Aider / Cline talk to OAuth-only providers (Claude Pro, ChatGPT Pro, SuperGrok). The cold-start wave shaves ~19 seconds off `hermes` launch, browser-tool CDP calls run 180x faster, and `hermes tools` All-Platforms drops from 14s to under 1.5s. Two new messaging platforms (LINE and SimpleX Chat) and a Microsoft Graph foundation (Teams pipeline + webhook adapter) land alongside `/handoff` that finally transfers sessions live, `vision_analyze` passing pixels through to vision-capable models, `x_search` as a first-class tool, LSP semantic diagnostics on every `write_file` / `patch`, a unified pluggable `video_generate`, a `computer_use` cua-driver backend, cross-session 1-hour Claude prompt caching, a per-turn file-mutation verifier, plus 9 new optional skills. 50+ P1 closures, 12 P0 closures.

-## ✨ Highlights
-
-- **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.

-- **`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.

-
-- **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`.

-- **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))
-
-- **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 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))
-
-- **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))
-
-- **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))
-
-- **`/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))
-
-- **`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))
-
-- **`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))
-
-- **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))
-
-- **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))
-
-- **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))
-
-- **`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))
-
-- **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))
-
-- **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))
-
-- **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))
-
-- **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))
-
-- **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))

([#24182](https://github.com/NousResearch/hermes-agent/pull/24182), [#25769](https://github.com/NousResearch/hermes-agent/pull/25769))
-
-- **`hermes-skills/huggingface` as a trusted default tap** — community skills index from huggingface.co/skills is available by default in the Skills Hub. ([#26219](https://github.com/NousResearch/hermes-agent/pull/26219))
-
-- **9 new optional skills** — Hyperliquid (perp/spot trading via SDK + REST) (@kshitijk4poor & Hermes), Yahoo Finance market data, api-testing (REST/GraphQL debug), unified EVM multi-chain skill (folds #25291 + #2010 + base/), darwinian-evolver, osint-investigation (closes #355), pinggy-tunnel, watchers (RSS/HTTP/GitHub via cron), Notion overhaul for the Developer Platform (May 2026).

-
-- **API server exposes run approval events** — long-running runs surface approval requests over the API stream, no more silent stalls. (salvage of [#20311](https://github.com/NousResearch/hermes-agent/pull/20311)) ([#21899](https://github.com/NousResearch/hermes-agent/pull/21899))
-
-- **`/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))
-
-- **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 + 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))

-Browser Provider ABC
-====================
-
-Defines the pluggable-backend interface for cloud browser providers
-(Browserbase, Browser Use, Firecrawl, …). Providers register instances via
-:meth:`PluginContext.register_browser_provider`; the active one (selected via
-``browser.cloud_provider`` in ``config.yaml``) services every cloud-mode
-``browser_*`` tool call.
-
-Providers live in ``<repo>/plugins/browser/<name>/`` (built-in, auto-loaded as
-``kind: backend``) or ``~/.hermes/plugins/browser/<name>/`` (user, opt-in via
-``plugins.enabled``).
-
-This ABC mirrors :class:`agent.web_search_provider.WebSearchProvider` (PR
-#25182) — same shape, same registration flow, same picker integration. The
-legacy in-tree ``tools.browser_providers.base.CloudBrowserProvider`` ABC was
-deleted in PR #25214 (this work) along with the per-vendor inline modules in
-``tools/browser_providers/``; the lifecycle contract documented below is
-preserved bit-for-bit so the tool wrapper (:mod:`tools.browser_tool`) does
-not have to translate.
-
-Session metadata contract (preserved from the legacy ``CloudBrowserProvider``)::
-
-    {
-        "session_name": str,        # unique name for agent-browser --session
-        "bb_session_id": str,       # provider session ID (for close/cleanup)
-        "cdp_url": str,             # CDP websocket URL
-        "features": dict,           # feature flags that were enabled
-        "external_call_id": str,    # optional, managed-gateway billing key
-    }
-
-``bb_session_id`` is a legacy key name kept verbatim for backward compat with
-:mod:`tools.browser_tool` — it holds the provider's session ID regardless of

-Browser Provider Registry
-=========================
-
-Central map of registered cloud browser providers. Populated by plugins at
-import-time via :meth:`PluginContext.register_browser_provider`; consumed by
-:func:`tools.browser_tool._get_cloud_provider` to route each cloud-mode
-``browser_*`` tool call to the active backend.
-
-Active selection
-----------------
-The active provider is chosen by configuration with this precedence:
-
-1. ``browser.cloud_provider`` in ``config.yaml`` (explicit override).
-2. Legacy preference order — ``browser-use`` → ``browserbase`` — filtered by
-   availability. Matches the historic auto-detect order in
-   :func:`tools.browser_tool._get_cloud_provider` (Browser Use checked first
-   because it covers both the managed Nous gateway and direct API key path;
-   Browserbase as the older direct-credentials fallback). ``firecrawl`` is
-   intentionally NOT in the legacy walk — users only get Firecrawl as a
-   cloud browser when they explicitly set ``browser.cloud_provider:
-   firecrawl``, matching pre-migration behaviour where Firecrawl was never
-   auto-selected.
-3. Otherwise ``None`` — the dispatcher falls back to local browser mode.
-
-The explicit-config branch (rule 1) intentionally ignores ``is_available()``
-so the dispatcher surfaces a typed "X_API_KEY is not set" error to the user
-instead of silently switching backends. Matches the legacy
-:func:`tools.browser_tool._get_cloud_provider` behaviour for configured names.
-
-Note: there is no "capability" split here (unlike the web subsystem, which
-has search/extract/crawl). Every browser provider implements the full
-:class:`agent.browser_provider.BrowserProvider` lifecycle; the registry's
-job is purely selection, not capability routing.

-    rejected replayed ``encrypted_content`` reasoning items minted by
-    prior turns, and we stripped them.  That decision was wrong — xAI
-    explicitly relies on Hermes threading encrypted reasoning back across
-    turns for cross-turn coherence (the whole point of their partnership
-    integration).  We now replay encrypted reasoning on every Responses
-    transport (xAI, native Codex, custom relays) and let xAI tell us
-    explicitly if a specific surface ever rejects a payload.
-
-    ``replay_encrypted_reasoning`` is the per-session kill switch.  Some
-    OpenAI-compatible relays accept the request but later reject the
-    replayed encrypted blob with HTTP 400 ``invalid_encrypted_content``;
-    when that happens the retry loop calls
-    ``AIAgent._disable_codex_reasoning_replay`` which both strips cached
-    items from the conversation history and threads ``replay_enabled=False``
-    through this converter so subsequent turns send no reasoning items.
-
-    ``current_issuer_kind`` enables a per-item cross-issuer guard. The
-    Responses API's ``encrypted_content`` blob is decryptable only by the
-    endpoint that minted it — replaying a Codex-issued blob against xAI
-    (or vice versa) always yields HTTP 400 ``invalid_encrypted_content``
-    and breaks every subsequent turn in the same session.  When this
-    argument is provided and a reasoning item carries an ``_issuer_kind``
-    stamp from a different endpoint, the item is dropped from the replayed
-    input.  Legacy items without a stamp are still replayed
-    (backwards-compatible).  The two guards compose:
-    ``replay_encrypted_reasoning=False`` is the session-wide kill switch
-    (drops ALL replay); ``current_issuer_kind`` is the per-item filter
-    that runs only when replay is still enabled.

-# Event-driven Responses streaming
-#
-# OpenAI ships its consumer Codex backend (chatgpt.com/backend-api/codex) on
-# a different schedule from the openai Python SDK.  The high-level
-# ``client.responses.stream(...)`` helper reconstructs a typed Response from
-# the terminal ``response.completed`` event's ``response.output`` field, and
-# when that field drifts to ``null`` (gpt-5.5, May 2026) the SDK raises
-# ``TypeError: 'NoneType' object is not iterable`` mid-iteration.
-#
-# We sidestep the whole class of failure by going one level lower:
-# ``client.responses.create(stream=True)`` returns the raw AsyncIterable of
-# SSE events, and we assemble the final response object purely from
-# ``response.output_item.done`` events as they arrive.  We never read
-# ``response.completed.response.output`` for content reconstruction, so the
-# backend can return ``null``, ``[]``, a string, or omit the field entirely
-# and we don't care.
-#
-# This mirrors what the OpenClaw TS implementation does for the same backend
-# and is structurally immune to the bug class rather than patched.

-
-* :func:`compress_context` — the actual compression call.  Runs the

-  session_id, notifies plugin context engines / memory providers, and
-  returns the compressed message list and freshly-built system prompt.
-
-* :func:`try_shrink_image_parts_in_messages` — image-too-large recovery

-        directly — provider tools / gateway adapters consume them through
-        internal channels.
-      * Project-local environment files anywhere on disk: ``.env``,
-        ``.env.local``, ``.env.development``, ``.env.production``,
-        ``.env.test``, ``.env.staging``, ``.envrc``. These routinely hold

-        substitute.
-
-    **This is NOT a security boundary.** The terminal tool runs as the
-    same OS user with shell access; the agent can still ``cat auth.json``
-    or ``cat ~/.hermes/.env`` and exfiltrate the file. The read-deny exists
-    as defense-in-depth that:

-        for the shell.
-      * Surfaces a visible audit trail when something tries to read
-        credentials — easier to spot in logs than a generic ``cat``.
-
-    Treat any user-visible framing around this as "may help" rather than
-    "stops attackers." A determined model or malicious instruction can
-    always shell out.
-
-    Callers that resolve relative paths against a non-process cwd
-    (e.g. ``TERMINAL_CWD`` in ``tools/file_tools.py``) MUST pre-resolve
-    and pass the absolute path string.  This function's own ``resolve()``

-"""Async LSP client over stdin/stdout.
-
-One :class:`LSPClient` corresponds to one ``(language_server, workspace_root)``
-pair — exactly what OpenCode keys clients on, and the same shape Claude
-Code uses.  The client owns a child process, drives the JSON-RPC
-exchange, and exposes:
-
-- :meth:`open_file` / :meth:`change_file` — text document sync
-- :meth:`wait_for_diagnostics` — block until the server emits fresh
-  diagnostics for a specific file (or a timeout fires)
-- :meth:`diagnostics_for` — read the current per-file diagnostic store
-- :meth:`shutdown` — graceful close + SIGTERM/SIGKILL fallback
-
-The class is designed for async use from a single asyncio event loop.
-The :class:`agent.lsp.manager.LSPService` runs an event loop in a
-background thread so the synchronous file_operations layer can call
-into it via :func:`agent.lsp.manager.LSPService.touch_file`.
-
-Implementation notes:
-
-- Push diagnostics are stored per-URI in :attr:`_push_diagnostics` from
-  ``textDocument/publishDiagnostics`` notifications.  Pull diagnostics
-  go in :attr:`_pull_diagnostics`.  The merged view dedupes by content.
-
-- Whole-document sync.  Even when the server advertises incremental
-  sync, we send a single ``contentChanges`` entry replacing the
-  entire document.  Pretending to be incremental while sending a
-  full replacement is well-tolerated by every major server and saves
-  range bookkeeping.  See OpenCode's ``client.ts:584-659`` for the
-  same trick.
-
-- The "touch-file dance": every ``open_file`` call also fires a
-  ``workspace/didChangeWatchedFiles`` notification (CREATED on the
-  first open, CHANGED thereafter).  Some servers (clangd, eslint)
-  only re-scan when this notification fires, even though the LSP spec
-  doesn't strictly require it.
-
-- ``ContentModified`` (-32801) errors get retried with exponential
-  backoff up to 3 times.  This matches Claude Code's
-  ``LSPServerInstance.sendRequest``.

-"""Structured logging with steady-state silence for the LSP layer.
-
-The LSP layer fires on every write_file/patch.  In a busy session
-that's hundreds of events.  We want users to be able to ``rg`` the
-log for "did LSP fire on that edit?" without drowning in noise.
-
-The level model:
-
-- ``DEBUG`` for steady-state events that have no novel signal:
-  ``clean``, ``feature off``, ``extension not mapped``, ``no project
-  root for already-announced file``, ``server unavailable for
-  already-announced binary``.  These never reach ``agent.log`` at the
-  default INFO threshold.
-
-- ``INFO`` for state transitions worth surfacing exactly once per
-  session: ``active for <root>`` the first time a (server_id,
-  workspace_root) client starts, ``no project root for <path>``
-  the first time we see that file.  Plus every diagnostic event
-  (those are inherently rare and per-edit, exactly what users grep
-  for).
-
-- ``WARNING`` for action-required failures: ``server unavailable``
-  (binary not on PATH) the first time per (server_id, binary),
-  ``no server configured`` once per language.  Per-call WARNING for
-  timeouts and unexpected bridge exceptions.
-
-The dedup is in-process module-level sets.  Each set grows at most by
-the number of distinct (server_id, root) and (server_id, binary)
-pairs touched in one Python process — bytes of memory in even an
-aggressive monorepo session.  Bounded LRU was rejected: evicting an
-entry would risk re-firing the WARNING/INFO line we explicitly want
-to suppress.

-"""Service-level orchestration for LSP clients.
-
-The :class:`LSPService` is the bridge between the synchronous
-file_operations layer and the async :class:`agent.lsp.client.LSPClient`.
-
-Design choices:
-
-- A **single asyncio event loop** runs in a background thread.  All
-  client work happens on that loop.  Synchronous callers from
-  ``tools/file_operations.py`` use :meth:`get_diagnostics_sync` to
-  open + wait + drain in one blocking call.
-
-- One client per ``(server_id, workspace_root)`` key.  Lazy spawn:
-  the first request for a key spawns the client; subsequent requests
-  re-use it.
-
-- A **broken-set** records ``(server_id, workspace_root)`` pairs that
-  failed to spawn or initialize.  These are never retried for the
-  life of the service.  Mirrors OpenCode's design.
-
-- A **delta baseline** map keeps "diagnostics-as-of-the-last-snapshot"
-  per file.  ``snapshot_baseline()`` is called BEFORE a write; the
-  next ``get_diagnostics_sync()`` returns only diagnostics that
-  weren't in the baseline.  This is the lift from Claude Code's
-  ``beforeFileEdited`` / ``getNewDiagnostics`` pattern, except wired
-  to the local LSP layer instead of MCP IDE RPC.
-
-The service is **off by default** — call :meth:`is_active` to check
-whether it's actually doing anything.  When LSP is disabled in
-config, when no git workspace can be detected, when all configured
-servers are missing binaries and auto-install is off, ``is_active``
-returns False and the file_operations layer falls through to the
-in-process syntax check.

-"""Diff-aware line-shift map for cross-edit LSP delta filtering.
-
-When an edit deletes or inserts lines in the middle of a file, every
-diagnostic below the edit point shifts to a new line number.  The
-LSPService delta filter subtracts the pre-edit baseline from the
-post-edit diagnostics keyed on ``(severity, code, source, message,
-range)`` — without an adjustment, the shifted-but-otherwise-identical
-diagnostics look brand-new and the agent gets flooded with noise.
-
-The fix used here is the same trick git's blame and unified diff use:
-build a piecewise-linear map from pre-edit line numbers to post-edit
-line numbers, then apply that map to baseline diagnostics before the
-set-difference.  Diagnostics whose pre-edit line is in a region the
-edit deleted return ``None`` and are dropped from the baseline (they
-genuinely no longer apply).
-
-Trade-off vs. dropping range from the key entirely (the previous
-fix): preserves the "new instance of an identical error at a
-different line" signal — if the model introduces a second instance
-of the same error class at a different location, that one will be
-surfaced as new instead of swallowed by content-only dedup.
-
-The map is derived from ``difflib.SequenceMatcher.get_opcodes()`` and
-exposed as a single callable so callers don't have to reason about
-diff regions.

-
-Hermes pulls API keys from Bitwarden Secrets Manager at process startup
-so they don't have to live in plaintext in ``~/.hermes/.env``.
-
-Design summary
---------------
-
-* The ``bws`` binary is auto-installed into ``<hermes_home>/bin/bws`` on
-  first use.  Hermes pins one version (``_BWS_VERSION``) and downloads
-  the matching asset from the official GitHub Releases page, verifying
-  the SHA-256 against the release's published checksum file.
-* The access token is stored in ``~/.hermes/.env`` as
-  ``BWS_ACCESS_TOKEN`` (or whatever name the user picked in
-  ``secrets.bitwarden.access_token_env``).  This is the one
-  bootstrap secret — every other provider key can live in Bitwarden.
-* Pulling secrets is a single ``bws secret list <project_id>
-  --output json`` call.  We cache the result in-process for
-  ``cache_ttl_seconds`` so back-to-back ``hermes`` invocations don't
-  hammer the API.
-* Failures NEVER block Hermes startup.  Missing binary, no network,
-  expired token, etc. all emit a one-line warning and continue with
-  whatever credentials ``.env`` already had.
-
-The module is intentionally subprocess-driven rather than going through
-the ``bitwarden-sdk-secrets`` Python package: one cross-platform binary
-is easier to lazy-install than a wheels-with-Rust-extension dependency.

-"""Skill bundles — aliases that load multiple skills under one slash command.
-
-A skill bundle is a small YAML file that names a set of skills to load
-together. Invoking ``/<bundle-name>`` from the CLI or gateway loads every
-referenced skill's full content into a single user message, the same way
-``/<skill-name>`` does — but for N skills at once.
-
-Storage
--------
-Bundles live in ``~/.hermes/skill-bundles/*.yaml`` (and the equivalent
-profile-aware directory under ``HERMES_HOME``). Each file looks like::
-
-    name: backend-dev
-    description: Backend feature work — code review, testing, PR workflow.
-    skills:
-      - github-code-review
-      - test-driven-development
-      - github-pr-workflow
-    instruction: |
-      Optional extra guidance to inject above the skill bodies.
-
-The file's stem is treated as a fallback name when ``name:`` is absent, so
-dropping a YAML into the directory is enough to register a new bundle.
-
-Conflict resolution
--------------------
-If a bundle and a skill share the same slash name, the bundle wins. The
-slash command dispatch checks bundles first, then falls back to skills.
-This is the intended behavior — a user who names a bundle ``research``
-explicitly wants ``/research`` to mean their bundle, not whatever skill
-happens to share the slug.
-
-Public API
-----------
-- :func:`get_skill_bundles` — return ``{"/slug": bundle_info}``
-- :func:`resolve_bundle_command_key` — map a user-typed command to its slug
-- :func:`build_bundle_invocation_message` — produce the full user message
-- :func:`reload_bundles` — re-scan disk and return a diff
-- :func:`list_bundles` — return rich info for display (``hermes bundles``)
