+  #
+  # This job has its own concurrency group as defense-in-depth: if the
+  # top-level group is ever loosened, queued move-mains will run serially
+  # in arrival order, each one running the ancestor check below and either
+  # advancing :main or skipping.  `cancel-in-progress: false` matches the
+  # top-level setting — we don't want rapid pushes to cancel a queued
+  # move-main, because the ancestor check is the real safety mechanism
+  # and queueing is cheap (move-main is a ~30s registry op).

-Implementation notes:
-
-- The plugin uses `multiprocessing.get_context("spawn")`, which works on
-  Linux, macOS, and Windows alike (POSIX `fork` is not used).
-- 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.

-## 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.

 ## CLI vs Messaging Quick Reference

-## 省去到处收集 API Key — Nous Portal
-
-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：
-
-- **300+ 模型** — 用 `/model <name>` 随时切换
-- **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)。
-
-你随时可以按工具单独切回自己的 API Key — Gateway 是按工具粒度生效的，不是一刀切。

-
-Provides keyless authentication for Microsoft Foundry deployments using the

-→ workload identity → managed identity → VS Code → Azure CLI → azd →
-PowerShell → broker).
-
-Architecture mirrors `agent/bedrock_adapter.py`:
-
-* Lazy import. `azure-identity` is only loaded when ``model.auth_mode =
-  entra_id`` is selected. Users who stick with `AZURE_FOUNDRY_API_KEY`
-  never pay the import cost.
-* SDK-callable contract. The public entry point ``build_token_provider``
-  returns a zero-arg callable produced by ``get_bearer_token_provider`` —
-  this is exactly the value Microsoft's documented sample plugs into
-  ``OpenAI(api_key=token_provider, base_url=...)``. The OpenAI SDK calls
-  it before every request, so token refresh is transparent.
-* Three explicit consumer-side helpers (display / cache / http-bearer)
-  rather than one generic "materialize" function — splitting them by
-  purpose prevents accidental token-minting in logging paths or token
-  leakage into cache keys / dashboard JSON.
-* No persisted JWT. ``azure-identity`` caches in-process and (where
-  available) in the OS keychain or ``~/.IdentityService``. Hermes does
-  not duplicate that storage in ``auth.json``.

-    "verbosity. Frustration signals like 'stop doing X', 'this is too "
-    "verbose', 'don't format like this', 'why are you explaining', "
-    "'just give me the answer', 'you always do Y and I hate it', or an "
-    "explicit 'remember this' are FIRST-CLASS skill signals, not just "
-    "memory signals. Update the relevant skill(s) to embed the "
-    "preference so the next session starts already knowing.\n"
-    "  • User corrected your workflow, approach, or sequence of steps. "
-    "Encode the correction as a pitfall or explicit step in the skill "
-    "that governs that class of task.\n"
-    "  • Non-trivial technique, fix, workaround, debugging path, or "
-    "tool-usage pattern emerged that a future session would benefit "
-    "from. Capture it.\n"
-    "  • A skill that got loaded or consulted this session turned out "
-    "to be wrong, missing a step, or outdated. Patch it NOW.\n\n"
-    "Preference order — prefer the earliest action that fits, but do "
-    "pick one when a signal above fired:\n"
-    "  1. UPDATE A CURRENTLY-LOADED SKILL. Look back through the "
-    "conversation for skills the user loaded via /skill-name or you "
-    "read via skill_view. If any of them covers the territory of the "
-    "new learning, PATCH that one first. It is the skill that was in "
-    "play, so it's the right one to extend.\n"
-    "  2. UPDATE AN EXISTING UMBRELLA (via skills_list + skill_view). "
-    "If no loaded skill fits but an existing class-level skill does, "
-    "patch it. Add a subsection, a pitfall, or broaden a trigger.\n"
-    "  3. ADD A SUPPORT FILE under an existing umbrella. Skills can be "
-    "packaged with three kinds of support files — use the right "
-    "directory per kind:\n"
-    "     • `references/<topic>.md` — session-specific detail (error "
-    "transcripts, reproduction recipes, provider quirks) AND "
-    "condensed knowledge banks: quoted research, API docs, external "
-    "authoritative excerpts, or domain notes you found while working "
-    "on the problem. Write it concise and for the value of the task, "
-    "not as a full mirror of upstream docs.\n"
-    "     • `templates/<name>.<ext>` — starter files meant to be "
-    "copied and modified (boilerplate configs, scaffolding, a "
-    "known-good example the agent can `reproduce with modifications`).\n"
-    "     • `scripts/<name>.<ext>` — statically re-runnable actions "
-    "the skill can invoke directly (verification scripts, fixture "
-    "generators, deterministic probes, anything the agent should run "
-    "rather than hand-type each time).\n"
-    "     Add support files via skill_manage action=write_file with "
-    "file_path starting 'references/', 'templates/', or 'scripts/'. "
-    "The umbrella's SKILL.md should gain a one-line pointer to any "
-    "new support file so future agents know it exists.\n"
-    "  4. CREATE A NEW CLASS-LEVEL UMBRELLA SKILL when no existing "
-    "skill covers the class. The name MUST be at the class level. "
-    "The name MUST NOT be a specific PR number, error string, feature "
-    "codename, library-alone name, or 'fix-X / debug-Y / audit-Z-today' "
-    "session artifact. If the proposed name only makes sense for "
-    "today's task, it's wrong — fall back to (1), (2), or (3).\n\n"
-    "User-preference embedding (important): when the user expressed a "
-    "style/format/workflow preference, the update belongs in the "
-    "SKILL.md body, not just in memory. Memory captures 'who the user "
-    "is and what the current situation and state of your operations "
-    "are'; skills capture 'how to do this class of task for this "
-    "user'. When they complain about how you handled a task, the "
-    "skill that governs that task needs to carry the lesson.\n\n"
-    "If you notice two existing skills that overlap, note it in your "
-    "reply — the background curator handles consolidation at scale.\n\n"
-    "Protected skills (DO NOT edit these):\n"
-    "  • Bundled skills (shipped with Hermes, e.g. 'hermes-agent').\n"
-    "  • Hub-installed skills (installed via 'hermes skills install').\n"
-    "Pinned skills (marked via 'hermes curator pin') CAN be improved — "
-    "pin only blocks deletion/archive/consolidation by the curator, not "
-    "content updates. Patch them when a pitfall or missing step turns up, "
-    "same as any other agent-created skill.\n"
-    "If the only skills that need updating are protected, say\n"
-    "'Nothing to save.' and stop.\n\n"
-    "Do NOT capture (these become persistent self-imposed constraints "
-    "that bite you later when the environment changes):\n"
-    "  • Environment-dependent failures: missing binaries, fresh-install "
-    "errors, post-migration path mismatches, 'command not found', "
-    "unconfigured credentials, uninstalled packages. The user can fix "
-    "these — they are not durable rules.\n"
-    "  • Negative claims about tools or features ('browser tools do not "
-    "work', 'X tool is broken', 'cannot use Y from execute_code'). These "
-    "harden into refusals the agent cites against itself for months "
-    "after the actual problem was fixed.\n"
-    "  • Session-specific transient errors that resolved before the "
-    "conversation ended. If retrying worked, the lesson is the retry "
-    "pattern, not the original failure.\n"
-    "  • One-off task narratives. A user asking 'summarize today's "
-    "market' or 'analyze this PR' is not a class of work that warrants "
-    "a skill.\n\n"
-    "If a tool failed because of setup state, capture the FIX (install "
-    "command, config step, env var to set) under an existing setup or "
-    "troubleshooting skill — never 'this tool does not work' as a "
-    "standalone constraint.\n\n"
-    "'Nothing to save.' is a real option but should NOT be the "
-    "default. If the session ran smoothly with no corrections and "

-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.

-    ``is_xai_responses`` is kept for transport signature compatibility but
-    no longer suppresses encrypted reasoning replay.  Earlier (PR #26644,
-    May 2026) we believed xAI's OAuth/SuperGrok ``/v1/responses`` surface
-    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.
+    ``is_xai_responses=True`` strips ``encrypted_content`` from replayed
+    reasoning items.  xAI's OAuth/SuperGrok ``/v1/responses`` surface
+    rejects encrypted reasoning blobs minted by prior turns: the request
+    streams an ``error`` SSE frame before ``response.created`` and the
+    OpenAI SDK collapses it into a generic stream-ordering error.  Native
+    Codex (chatgpt.com backend-api) DOES accept replayed encrypted_content
+    — keep the default off.

-# 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
-  configured compressor, splits the SQLite session, rotates 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
-  helper that re-encodes ``data:image/...;base64,...`` parts at a smaller
-  size so retries can fit under provider ceilings (Anthropic's 5 MB).

-        OAuth tokens, and HMAC secrets that the agent never needs to read
-        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
-        API keys, database passwords, and other credentials for the user's

-        need to read these — ``.env.example`` is the documented-shape
-        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:

-      * Returns a clear error to models that respect tool denials, which
-        empirically prompts most modern models to stop rather than reach
-        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()``
-    is anchored at the Python process cwd, so a relative input like

-# from a different shell.
-#
-# Soft guard, NOT a security boundary: the agent runs as the same OS user
-# and has unrestricted terminal access, so this returns a warning the model
-# can choose to honor or override with ``cross_profile=True``. Same shape
-# as the dangerous-command approval flow — the agent is told the boundary
-# exists, and explicit user direction is required to cross it.
-#
-# Reference: May 2026 incident where a hermes-security profile session
-# edited skills under both ``~/.hermes/profiles/hermes-security/skills/``

-# the second path belonged to a different profile.

-
-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``)
-- :func:`save_bundle` / :func:`delete_bundle` — file-level operations

-* ``_should_parallelize_tool_batch`` / ``_extract_parallel_scope_path`` /

-* ``_trajectory_normalize_msg`` — strip image blobs from a message for

-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`
-re-checks defensively).
-
-Providers live in ``<repo>/plugins/transcription/<name>/`` (built-in
-plugins, none shipped today) or
-``~/.hermes/plugins/transcription/<name>/`` (user-installed).
-
-Response contract
------------------

-
-    success      bool
-    transcript   str       transcribed text (empty when success=False)
