Run the image's built-in entrypoint against `--help` and `dashboard --help`

# Run the docker-integration test suite against the freshly-built
# image already loaded into the local daemon (`:test`). These tests
# are excluded from the sharded `tests.yml :: test` matrix on purpose
# (see `_SKIP_PARTS` in scripts/run_tests_parallel.py) because each
# shard would otherwise reach the session-scoped ``built_image``
# fixture in ``tests/docker/conftest.py`` and start a 3-7min
# ``docker build`` — guaranteed to
# die in fixture setup.
#
# Piggybacking here avoids a second image build: the smoke test
# already proved the image loads + runs, so the daemon has it under
# `${IMAGE_NAME}:test` and we just point ``HERMES_TEST_IMAGE`` at
# that. The fixture's ``HERMES_TEST_IMAGE`` branch (see
# tests/docker/conftest.py:62-63) short-circuits the rebuild.
#
# Why this job and not a standalone one: the image is 5GB+; passing
# it between jobs via ``docker save``/``upload-artifact`` is slower
# than the build itself. Reusing the existing daemon state is the
# cheapest path to coverage on every PR that touches docker code.

#
# Why this job and not a standalone one: the image is 5GB+; passing

#
# Why per-file (not per-test): per-test spawn cost (~250ms × 17k
# tests = 70min CPU minimum) blew the wall-clock budget. Per-file
# spawn (~250ms × ~850 files = ~3.5min) fits while still giving
# every file a fresh interpreter — the only isolation boundary
# that matters in practice (cross-file leakage was the original
# flake source; intra-file is the test author's responsibility).
#
# Why drop xdist entirely: xdist's persistent workers accumulate
# state across files, which is exactly the leakage we wanted to
# fix. ThreadPoolExecutor + subprocess.run is ~60 lines and does
# the job with cleaner semantics.
#
# Matrix slicing (--slice I/N): files are distributed across 6
# jobs by cached duration (LPT algorithm) so each job gets
# roughly equal wall time. Without a cache, files default to 2s
# estimate and get split roughly evenly by count — still correct,
# just not perfectly balanced.
# File list is pre-computed by the generate job (--generate-slices)
# which runs LPT distribution once and passes the file list to each
# matrix job via --files. Previously each job re-discovered files and
# re-ran LPT independently — redundant N times.

The WebSocket/JSON-RPC transport lives in the framework-agnostic `apps/shared` package (`@hermes/shared` — `JsonRpcGatewayClient` + WS URL helpers), which the web dashboard (`web/`) also consumes; **desktop has no build/runtime dependency on the dashboard frontend** — it spawns a headless `hermes serve` backend server (the same gateway `dashboard` serves, minus the browser UI). `dashboard` and `serve` share `cmd_dashboard`/`start_server` but are independent surfaces — neither launches the other. The one exception is a backward-compat *fallback*: `serve` is newer, so the desktop spawn (`electron/backend-command.cjs` + `backendSupportsServe()` in `main.cjs`) detects whether the resolved runtime registers `serve` and, only when it does not (an older managed install / PATH `hermes` the app hasn't updated yet), rewrites the argv to the legacy `dashboard --no-open`.

### Subprocess-per-test isolation
### Subprocess-per-test-file isolation
Every test runs in a freshly-spawned Python subprocess via the in-tree plugin
at `tests/_isolate_plugin.py`. This means module-level dicts/sets and
ContextVars from one test cannot leak into the next — the historic
`_reset_module_state` autouse fixture is gone.
Every test file runs in a freshly-spawned Python subprocess via `run_tests_parallel.py`. This means module-level dicts/sets and
ContextVars from one test file cannot leak into the next.
Implementation notes:
### Why the wrapper
- 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.
| | Without wrapper | With wrapper |
| ------------------- | ------------------------------------------- | ----------------------------------------- |
| Provider API keys | Whatever is in your env (auto-detects pool) | All env vars except a specific few unset. |
| HOME / `~/.hermes/` | Your real config+auth.json | Temp dir per test |
| Timezone | Local TZ (PDT etc.) | UTC |
| Locale | Whatever is set | C.UTF-8 |
### Why the wrapper (and why the old "just call pytest" doesn't work)
Five real sources of local-vs-CI drift the script closes:
| | Without wrapper | With wrapper |
|---|---|---|
| Provider API keys | Whatever is in your env (auto-detects pool) | All `*_API_KEY`/`*_TOKEN`/etc. unset |
| HOME / `~/.hermes/` | Your real config+auth.json | Temp dir per test |
| Timezone | Local TZ (PDT etc.) | UTC |
| Locale | Whatever is set | C.UTF-8 |
| xdist workers | `-n auto` = all cores | `-n auto` (safe — subprocess isolation prevents cross-worker flakes) |
`tests/conftest.py` also enforces points 1-4 as an autouse fixture so ANY pytest
invocation (including IDE integrations) gets hermetic behavior — but the wrapper
is belt-and-suspenders.
### Running without the wrapper (only if you must)
If you can't use the wrapper (e.g. inside an IDE that shells pytest directly),
at minimum activate the venv. The isolation plugin loads automatically from
`addopts` in `pyproject.toml`, so you get the same per-test process isolation
either way.
```bash
source .venv/bin/activate # or: source venv/bin/activate
python -m pytest tests/ -q
```
If you need to bypass isolation for fast feedback while debugging:
```bash
python -m pytest tests/agent/test_foo.py -q --no-isolate
```
Always run the full suite before pushing changes.

## Third-Party Product Integrations: Ship as a Standalone Plugin
The same rule extends to **any plugin that integrates someone else's product or project** — observability/metrics backends, vendor SaaS connectors, analytics dashboards, paid-service tie-ins, and similar third-party integrations. **These do not land in this repo.**
The reason is maintenance load, not quality. Every external product absorbed into the core tree becomes ours to keep working against a fast-moving codebase, for a backend we don't own and can't control. Hermes ships a lot and the core moves quickly; coupling third-party products into it creates an open-ended burden on the maintainers.
Publish these as a **standalone plugin repo** instead:
- Implement the relevant ABC and use the existing plugin discovery path (`~/.hermes/plugins/`, project `.hermes/plugins/`, or a pip entry point) — see [Build a Hermes Plugin](https://hermes-agent.nousresearch.com/docs/guides/build-a-hermes-plugin)
- Register lifecycle hooks (`pre_tool_call`, `post_tool_call`, `pre_llm_call`, `post_llm_call`, `on_session_start`, `on_session_end`), tools (`ctx.register_tool`), and CLI subcommands (`ctx.register_cli_command`) through the surface we already expose — no core changes needed
- If your plugin needs a capability the framework doesn't expose, that's a feature request to **widen the generic plugin surface** (a new hook or `ctx` method) — never special-case your plugin in core
- Promote it in the [Nous Research Discord](https://discord.gg/NousResearch) `#plugins-skills-and-skins` channel so users can find and install it
A well-built third-party-product plugin can clear automated review and still be closed for this reason — it's a placement decision, not a verdict on the code. PRs that add such a directory under `plugins/` will be closed with a pointer to publish it as its own repo.

``_previous_summary`` is per-session iterative-summary state. It is
cleared on ``on_session_reset()`` (/new, /reset), but session *end*
(CLI exit, gateway expiry, session-id rotation) goes through
``on_session_end()`` instead — which inherited a no-op from
``ContextEngine``. Without clearing here, a cron/background session's
summary could survive on a reused compressor instance and leak into the
next live session via the ``_generate_summary()`` iterative-update path
(#38788). ``compress()`` already guards the leak at the point of use;
this is defense-in-depth that drops the stale summary the moment the
owning session ends.
Session end (CLI exit, gateway expiry, session-id rotation) goes
through this method rather than ``on_session_reset()`` (/new, /reset).
The original fix (#38788) only cleared ``_previous_summary``, but the
same cross-session contamination risk applies to every per-session
variable that ``on_session_reset()`` clears: stale
``_ineffective_compression_count`` can suppress compression in a
subsequent live session; ``_summary_failure_cooldown_until`` can block
summary generation; ``_last_compress_aborted`` can make callers think
compression is still aborted; ``_last_aux_model_failure_*`` can surface
stale error warnings; ``_last_summary_dropped_count`` /
``_last_summary_fallback_used`` can produce misleading user warnings.
``compress()`` already guards ``_previous_summary`` leakage at the
point of use; this is defense-in-depth that resets the full per-session
surface the moment the owning session ends.

This method removes orphaned results and strips orphaned tool_calls

Previous approach inserted stub ``role="tool"`` results for orphaned

"""Terminal renderer for the learning timeline (learned skills + memories).
The desktop app (``apps/desktop/src/app/starmap``) paints a GPU radial
constellation; a terminal can't, so this is a *rendition* of the same data as a
timeline bar chart — date rows, proportional skill/memory bars colored by the
day's dominant category, and a cumulative trajectory sparkline — plus per-slice
bucket metadata the TUI walks as a tree. The age gradient and complementary
memory ink are ported from the desktop source, not guessed.
Grids are emitted as style runs — ``[text, style, alpha, hex?]`` — so each
consumer maps the semantic style + brightness onto its own palette; the
optional 4th element overrides the base color (category heatmap). Pure,
stdlib-only.

"""User-initiated edit/delete for journey nodes (learned skills + memories).
The journey graph (``agent.learning_graph``) gives every node a stable id:
- **skills** → the skill name (e.g. ``"debugging-hermes-desktop"``)
- **memories** → ``memory:<source>:<index>`` where ``source`` is ``memory``
(``MEMORY.md``) or ``profile`` (``USER.md``) and ``index`` is the node's
position in the combined card list (``MEMORY.md`` cards first, then
``USER.md``).
This module maps a node id back to its on-disk home and performs the mutation,
shared by the CLI (``hermes journey delete|edit``), the TUI ``/journey`` overlay
(gateway RPCs), and the desktop GUI (REST). Deleting a skill *archives* it
(recoverable via ``hermes curator restore``); deleting a memory rewrites its
file. Pure stdlib + existing skill/memory helpers.

yes/no question — "is this an output-cap error at all?" — across providers
whose exact wording we may not yet parse a number from.
Why this matters: an output-cap 400 is deterministic (every retry with the
same ``max_tokens`` gets the identical rejection). If such an error is
misclassified as a context-overflow it gets routed into the compression
loop, the compressor re-issues the call with the same oversized
``max_tokens``, the provider rejects it identically, and the session
death-loops until "cannot compress further" (issue #55546, DashScope/Qwen:
"Range of max_tokens should be [1, 65536]"). Compression cannot help an
output-cap error — the input already fits.
The signal: the error talks about ``max_tokens`` (or its aliases) as a
cap/range/limit, and does NOT talk about the INPUT/prompt/context window
being too long. When both are present we defer to the context-overflow
path (a real input overflow can also mention max_tokens).

"""Wrap content from high-risk tools in untrusted-data delimiters.
Handles plain string content and multimodal content lists
(``[{"type": "text", "text": "..."}, {"type": "image_url", ...}]``).
Text parts inside a multimodal list are wrapped individually — the same
rules as plain string content — so vision-capable adapters still receive
a valid content list while an injection payload embedded in a text chunk
is still marked as untrusted data. Non-text parts (image_url, etc.) are
preserved unchanged. The outer list is rebuilt rather than returned by
identity, so callers must compare by value, not by ``is``.
Returns ``content`` unchanged when:
- the tool is not in the high-risk set
- the content is not a plain string (multimodal list, dict, None)
- the content is too short to be worth wrapping
- the content is already wrapped (re-entrancy guard, e.g. nested forwards)
- the content is neither a string nor a list (dict, None, …)
- (string) the content is too short to be worth wrapping
Wrapped string content is always neutralized (any embedded delimiter token
is defanged) and wrapped in exactly one well-formed block. There is no
"already wrapped" fast-path: such a check is attacker-forgeable — content
that merely starts with the opening tag would be returned with no data
framing at all — so re-wrapping (harmlessly) is the safe choice.

### How it works
The packaged app ships the Electron shell and a native React chat surface. On first launch it can install the Hermes Agent runtime into `HERMES_HOME` (`~/.hermes`, or `%LOCALAPPDATA%\hermes` on Windows) — the **same layout a CLI install uses**, so the two are interchangeable. Backend resolution first honours `HERMES_DESKTOP_HERMES_ROOT`, then a completed managed install, then a probed `hermes` on `PATH` (unless `HERMES_DESKTOP_IGNORE_EXISTING=1` is set), and finally an explicit `HERMES_DESKTOP_HERMES` command override for packagers/troubleshooting. The renderer (React, in `src/`) talks to a `hermes dashboard` backend over the `tui_gateway`/dashboard APIs and reuses the agent runtime rather than embedding `hermes --tui`. The install, backend-resolution, and self-update logic all live in `electron/main.cjs`.

The renderer (React, in `src/`) talks to a headless backend the app launches for you — a `hermes serve` process that serves the `tui_gateway` JSON-RPC/WebSocket API — through the framework-agnostic client in [`apps/shared`](../shared/) (the same client the web dashboard consumes), and reuses the agent runtime rather than embedding `hermes --tui`. The app is **self-contained**: it runs its own `hermes serve` backend and never opens or requires the web dashboard UI. (For backward compatibility, a runtime that predates the `serve` command automatically falls back to a headless `dashboard --no-open` — see `electron/backend-command.cjs` — so mid-upgrade installs never break.) The install, backend-resolution, and self-update logic all live in `electron/main.cjs`.
