- Use os.pathsep instead of literal ':' so Windows paths (C:\dir) and
the Windows separator ';' work correctly.
- Add 9 tests covering multi-root behavior: writes inside first/second
root, writes outside all roots, trailing/leading/double separators,
all-separators edge case, static deny priority, duplicate dedup.
- Update hermes_cli/tips.py tip string to mention multiple paths.
- Update docs to mention os.pathsep / ; on Windows.
Follow-up for salvaged PR #49557.
preexec_fn=os.setsid runs Python code in the forked child before exec,
which is unsafe in multi-threaded processes (CPython docs). When the
Desktop gateway loads native libraries (onnxruntime, BLAS, provider SDKs)
with active thread pools, the fork can SIGSEGV before the child execs.
Replace all preexec_fn usage with start_new_session=True, which provides
the same setsid/process-group semantics without running Python in the
fork. This is already the pattern used throughout hermes_cli/gateway.py
and hermes_cli/_subprocess_compat.py.

The autonomous self-improvement review fork could still write to a pinned
skill — only external/bundled/hub-installed/protected-builtin skills were
guarded. The curator skips pinned skills from every auto-transition; the
review fork is the same kind of no-user-present actor and must too.
Adds a pin check to _background_review_write_guard so background-origin
edit/patch/delete/write_file/remove_file on a pinned skill are refused.
Stricter than the foreground _pinned_guard (delete-only) by design: with
no user in the loop there is no one to consent to an edit.
Fixes#25839
The dangerous-command approval layer already blocks `hermes gateway
(stop|restart)`, `pkill/killall hermes|gateway`, and `kill ... $(pgrep ...)`.
A reporter noted on #33071 that the agent can still achieve the same
effect by driving launchd directly against the gateway's service label
(`launchctl stop ai.hermes.gateway`, `launchctl kickstart -k
system/ai.hermes.gateway`, etc.) or by substituting `pidof` for `pgrep`
in the kill-expansion form.
This widens the "Gateway lifecycle protection" block in
`tools/approval.py` to cover both vectors:
- `launchctl (stop|kickstart|bootout|unload|kill|disable|remove)`
scoped to commands that target a Hermes label (`hermes`,
`ai.hermes`). Read-only inspection (`launchctl print …`,
`launchctl list`) and operations against unrelated labels remain
unflagged.
- `kill ... $(pidof …)` and the backtick form, alongside the existing
`pgrep` expansion. `pidof` is the BSD/Linux equivalent and is
equally opaque to the `(pkill|killall) … hermes` name pattern.
Intentionally left out of scope: plain `kill -TERM <numeric_pid>` with
a PID looked up out-of-band. Catching that would require runtime PID
state and would break the existing
`TestPgrepKillExpansion::test_safe_kill_pid_not_flagged` contract,
which guarantees that a plain literal-PID `kill 12345` stays safe.
Natural-language skill search returned a short, arbitrary list and never
surfaced NVIDIA (or OpenAI/Anthropic/HuggingFace) skills. Two causes:
1. The runtime index collapses every GitHub tap into source="github", so
there was no way to find or filter by provider at the CLI — the per-tap
identity only existed in the docs-site catalog.
2. HermesIndexSource.search matched only name/description/tags (not the
identifier or provider) and broke at the first `limit` hits in raw index
order, burying the most relevant skills. `search` also defaulted to
--limit 10 against an 86k-entry catalog.
Changes:
- GitHubSource stamps a per-tap provider label (extra.provider) on each
skill via github_provider_for(); source stays "github" so dedup/floor/
index-skip logic is untouched. Flows into the built index.
- HermesIndexSource.search now matches identifier + provider too, and
collect-then-ranks (exact > prefix > whole-word > substring) instead of
break-at-limit.
- --source nvidia|openai|anthropic|huggingface|voltagent|gstack|minimax
provider filters for browse/search (narrows merged results by provider).
- search --limit default 10 -> 25; table Source column shows the provider
label for github skills.
Tested: 181 unit tests pass; E2E against the live runtime index confirms
'nvidia'/'cuda' searches now surface NVIDIA-provider skills and
--source nvidia narrows to exactly the NVIDIA catalog.
The post-update gateway restart path relaunched the gateway with the
venv's console `python.exe` (via `get_python_path()` in
`_gateway_run_args_for_profile`). On Windows this leaves a terminal
window open permanently: uv's `venv\Scripts\python.exe` is a launcher
shim that re-execs the *base* console interpreter, which allocates its
own conhost — and `CREATE_NO_WINDOW` cannot suppress that second window.
The clean-start path (`_spawn_detached`) already dodges this by routing
through `_resolve_detached_python` to use the windowless base
`pythonw.exe`; the restart watcher did not.
Symptom (reported on Windows 11): after an in-app GUI update, a console
window for the gateway stays open and never closes. Confirmed on the
reporter's box — the running gateway was `python.exe ... gateway run
--replace` with a live conhost child and the foreground "Press Ctrl+C to
stop" banner, born exactly at the update's "Restarting Windows gateway"
log line.
Fix:
- Add `gateway_windows.windowless_gateway_restart_spec(run_argv)` which
rewrites a console-python gateway argv into the windowless `pythonw.exe`
equivalent and returns the cwd + env overlay (VIRTUAL_ENV / PYTHONPATH /
HERMES_HOME) the base interpreter needs to import `hermes_cli` without
the venv launcher's site config. No-op on POSIX.
- `_spawn_gateway_restart_watcher` now applies that rewrite on Windows and
threads cwd= / env= into the inlined respawn Popen. Covers both restart
entry points (`launch_detached_profile_gateway_restart` and
`launch_detached_gateway_restart_by_cmdline`). CREATE_NO_WINDOW |
DETACHED_PROCESS | CREATE_BREAKAWAY_FROM_JOB and the breakaway-denied
fallback are all preserved.
Verified E2E on a real Windows 11 box: drove the actual watcher against a
dummy old-pid; the respawned gateway came up as `pythonw.exe` (zero
console python, no conhost child) and booted fully (housekeeping + kanban
dispatcher started → imports resolved under the base interpreter).
Tests: TestWindowlessGatewayRestartSpec (behavior) +
TestGatewayDetachedWatcherWindowsFlags regression assert. Pre-existing
Linux-only failures on a Windows host (SIGKILL, systemd, docker-root)
confirmed identical on the bare base.
On macOS, terminal(background=true) silently failed: the process returned a
session_id and exit_code=0 but the command never ran (empty stdout, no side
effects). Root cause is two interacting issues:
1. _find_shell was aliased to _find_bash, which prefers `shutil.which("bash")`
→ /bin/bash (GNU bash 3.2, still shipped on macOS) over $SHELL (/bin/zsh).
2. process_registry.spawn_local runs [shell, "-lic", "set +m; <cmd>"] with
stdin=/dev/null. bash 3.2 as a login shell sources ~/.bash_profile, which on
many macOS setups contains `exec /bin/zsh -l`; that exec replaces bash but
drops the -c argument, so the command is swallowed (exit 0, no output).
Decouple _find_shell from _find_bash: _find_shell now prefers the user's
configured $SHELL on POSIX (the shell they actually log in with), falling back
to _find_bash when $SHELL is unset/missing. _find_bash is unchanged, so callers
that genuinely need bash (e.g. the _run_bash login-shell snapshot) keep bash
semantics. zsh handles -lic correctly even with redirected stdin.
Salvaged from #42219 by @liuhao1024 (authorship preserved via cherry-pick).
On top of the original (8 unit tests covering $SHELL-set/unset/missing/empty,
Windows-ignores-$SHELL, _find_bash-unchanged), added an E2E regression test
that reproduces the real bash-3.2 login-shell swallow (exit 0 / no file) and
asserts the shell _find_shell selects actually executes a -lic background
command. Mutation-verified: reverting _find_shell to the bash alias fails the
$SHELL-preference test. Bug reproduced directly: /bin/bash 3.2 -lic with a
.bash_profile->exec-zsh creates no file; zsh -lic does.
Closes#42203. Supersedes #42290.
The cron runtime tripwire (_scan_cron_prompt) used a 10-char invisible-unicode
set while the install-time scanner (threat_patterns.INVISIBLE_CHARS) flags 17.
The cron-local set was missing U+2062-U+2064 (invisible math operators) and
U+2066-U+2069 (directional isolates), so a directive obfuscated with one of
those codepoints (e.g. "ig<U+2063>nore all previous instructions") slipped past
the runtime cron gate while being caught at install time.
Import the canonical set so the cron tripwire and install scanner can't drift
apart again. Emoji-ZWJ protection (_zwj_has_emoji_neighbour) is unchanged.

The known_c2_framework threat pattern included 'praxis' in its
alternation alongside genuine offensive-security tool brands (Cobalt
Strike, Sliver, Havoc, Mythic, Metasploit, Brainworm). Unlike those
distinctive brand names, 'praxis' is a common English word (Greek for
practice/action) and a legitimate agent name, so any context file that
mentioned an agent named Praxis matched at 'context' scope and the whole
AGENTS.md / SOUL.md was replaced with a [BLOCKED] placeholder before it
reached the system prompt.
Remove 'praxis' from the alternation and add a guard comment: every
token in this list must be a distinctive tool brand, not a common word.
Real C2 brands still fire.
The new _maybe_flag_poisoned_client tests built a provider via
get_or_build_provider without an interactive stdin. Under the hermetic
test env (no TTY, no cached tokens), the non-interactive guard in
mcp_oauth_manager._make_provider raised OAuthNonInteractiveError before
the provider was built, failing 6 tests in CI parity (they passed
locally where stdin was a TTY).
Thread monkeypatch into _provider_with_token_endpoint and present an
interactive stdin, matching the sibling test_manager_builds_hermes_provider_subclass.
Fixes#36767.
Two complementary recoveries for the recurring "delete three cache files and
re-auth by hand" ritual when an MCP server's dynamically-registered OAuth
client goes dead server-side (IdP redeploy / DB wipe / rebrand):
- Auto-heal (token-endpoint subset): HermesMCPOAuthProvider now sniffs
auth-flow responses and, on a 400/401 `invalid_client` from the discovered
token endpoint, backs up + deletes `<server>.client.json` and `.meta.json`
and clears the in-memory client so the SDK re-runs RFC 7591 dynamic client
registration on the next flow. Conservative by construction: only
dynamically-registered (non config-supplied) clients, only the token
endpoint, only on a word-boundary `invalid_client` match (so RFC 7591's
`invalid_client_metadata` does not trip it); best-effort so a miss never
breaks the live flow. Covers both code-exchange and refresh when the token
endpoint was discovered. Tokens are preserved.
- `hermes mcp reauth [<name>|--all]`: the reporter's primary symptom — the
IdP's in-browser "Redirect URI Mismatch" — produces no HTTP signal (the SDK
only sees a callback timeout), so it cannot be auto-detected. The new
command re-auths one or ALL `auth: oauth` servers, serially: one browser
flow at a time, which also fixes the startup popup storm when several
servers are stale at once. Single-server reauth is factored out of
`mcp login` and shared.
Tests: +14 (poison helper x2; token-endpoint detection x5 incl. wrong-endpoint,
success-response, pre-registered, and invalid_client_metadata negative guards;
a bridge integration test driving the real async_auth_flow generator to prove
the detection hook preserves the bidirectional asend() forwarding contract;
reauth CLI x6). Verified against the pinned mcp==1.26.0: scripts/run_tests.sh
122/122 green for the touched suites; check-windows-footguns.py and ruff clean.

Force redact_sensitive_text(force=True) on the browser_type text arg so
recognized credentials (API keys, tokens, JWTs) are masked in tool
progress, previews, callbacks, and return payloads even when the global
security.redact_secrets opt-out is set — a typed credential reaching chat
history is a security boundary, not log hygiene. Normal typed text matches
no pattern and stays fully readable for debuggability.
Tests assert the API-key-shaped secret is masked across every surface and
that normal text passes through unchanged.
After a prolonged outage the in-process network-error ladder escalates to
fatal and GatewayRunner._platform_reconnect_watcher rebuilds a fresh adapter
that reconnects through the bootstrap path. That path called
start_polling(drop_pending_updates=True), discarding every update Telegram
queued during the outage — all messages sent while the bot was down were
silently lost. The in-process ladder and 409-conflict handler already passed
drop_pending_updates=False; only bootstrap did not distinguish a cold first
boot from a reconnect.
Thread an is_reconnect signal from the watcher through
_connect_adapter_with_timeout into adapter.connect(). The base
BasePlatformAdapter.connect() gains a keyword-only is_reconnect=False so every
adapter inherits a tolerant signature (no per-platform breakage when the
runner forwards the kwarg). Telegram translates is_reconnect into
drop_pending_updates=not is_reconnect on both the polling and webhook bootstrap
calls. Cold boot still drops the stale queue; a watcher reconnect preserves it.

The detector folds absolute home / Hermes-home prefixes into their canonical
~/ and ~/.hermes/ forms so static patterns catch /home/alice/.bashrc the same
way they catch ~/.bashrc (abd69b81). On native Windows this fold never fired,
so terminal commands writing to shell startup files, ~/.ssh/authorized_keys,
or ~/.hermes/config.yaml / .env returned "safe" and skipped the approval
prompt — and config.yaml carries the approval policy itself.
Two compounding causes:
1. The fold ran after the backslash-escape strip (r\m -> rm), which dissolves
the backslash separators in a Windows path (C:\Users\alice\.bashrc ->
C:Usersalice...) before the fold could match. It now runs before the strip.
2. The fold only recognized POSIX absolute paths and only the home prefix,
leaving multi-segment backslash suffixes (\.ssh\authorized_keys) to be
mangled by the strip.
Consolidated into _home_prefix_fold_regex / _fold_home_prefixes: match a home
prefix with either separator, capture the rest of the path token, and
normalize its separators to / so multi-segment patterns match. The
degenerate-path guard generalizes count("/") >= 2 to "at least two components
below the root" (also rejecting a bare drive root C:\). HOME is consulted
directly because Windows' expanduser ignores it; the more specific Hermes home
is folded first, longest candidate first, so neither fold clobbers the other.
POSIX behavior unchanged; the r\m -> rm anti-obfuscation strip still runs.
Adds TestWindowsAbsolutePathFolding, which monkeypatches a Windows-style
HOME/HERMES_HOME so the behavior is also exercised on the CI runner.
* feat(moa): expose MoA presets as selectable virtual models
Reconstructed onto current main (PR #46081's base had diverged with no common
ancestor, marking the PR dirty so CI never dispatched). MoA is now a virtual
provider: each named preset is a selectable model under provider 'moa', and the
preset's aggregator is the acting model that answers and calls tools.
Reference models fan out in parallel via a bounded ThreadPoolExecutor (the same
batch pattern delegate_task uses) — all references dispatched at once, collected
when every one finishes, then handed to the aggregator. Output order is
preserved, failures and the MoA-recursion guard stay isolated per reference.
- Removed the old mixture_of_agents model tool and moa toolset.
- Added moa as a virtual provider in the provider/model inventory.
- /moa is shortcut behavior over model selection (default preset / named preset
/ one-shot prompt).
- Dashboard + Desktop manage named presets; presets appear in model pickers.
- Parallel reference fan-out in agent/moa_loop.py with regression test.
* fix(moa): thread moa_config through _run_agent to _run_agent_inner
The reconstructed gateway MoA wiring declared moa_config on _run_agent (the
profile-scoping wrapper) and used it inside _run_agent_inner, but the wrapper
never forwarded it — _run_agent_inner had no such parameter, so the runtime hit
NameError: name 'moa_config' is not defined on the compression-failure session
sync path. Add moa_config to _run_agent_inner's signature and forward it from
both wrapper call sites (multiplex and non-multiplex). Caught by
tests/gateway/test_compression_failure_session_sync.py on CI shard test(4).
* fix(moa): classify moa as a virtual provider in the catalog
The moa virtual provider has no PROVIDER_REGISTRY/ProviderProfile entry, so
provider_catalog() fell through to the default auth_type="api_key" with no
env vars — tripping two catalog invariants:
- test_provider_catalog: api_key providers must expose a credential env var
- test_provider_parity: every hermes-model provider must be desktop-configurable
moa already declares auth_type="virtual" in HERMES_OVERLAYS; consult that
overlay as an auth_type fallback so the catalog reports moa as virtual (no real
credential, no network endpoint). Exempt virtual providers from the desktop
parity union check the same way 'custom' is exempt — derived from the catalog,
not a hardcoded slug, so future virtual providers are covered too.
The trailing-whitespace expansion in _map_normalized_positions
unconditionally consumed whitespace after the matched region — including
the word-boundary space that separates the match from the next token.
This caused silent file corruption when the fuzzy matcher fell back to
the whitespace_normalized strategy.
Guard the expansion on the normalized match actually ending with
whitespace (i.e. the original had a run of spaces that were collapsed).
When the match ends with a non-space character, the first whitespace in
the original is a boundary and must not be consumed.
Fixes#52491
todo_tool crashed with `AttributeError: 'str' object has no attribute 'get'`
when the LLM emitted the `todos` param as a JSON-encoded string instead of an
array, or as a list containing non-dict items (observed intermittently on
Claude 4.5/4.6/4.7, and after a prior tool-call rejection where the model
"self-corrects" by wrapping the list in json.dumps).
Three additive guards, no behavior change for well-formed input:
- todo_tool(): if `todos` is a str, json.loads it; reject unparseable strings
and non-list values with a clear tool_error instead of crashing downstream.
- _validate(): non-dict items return a {id:"?", content:"(invalid item)"}
placeholder rather than calling .get() on a str/int/None.
- _dedupe_by_id(): non-dict items get a synthetic key so _validate handles them.
Salvaged from #14785 by @Tranquil-Flow (authorship preserved via cherry-pick).
Comprehensive tests: JSON-string coercion (parse / unparseable / non-list /
non-string), non-dict list items (str/None/int/mixed), and a well-formed-
unchanged regression class — both guards mutation-verified to fail without them.

coverage) and #16952 (bundled unrelated scope-creep).
During stdio MCP server startup, _run_stdio (an async method) called the
synchronous check_package_for_malware() inline. That makes a blocking
urllib HTTPS POST to api.osv.dev whose own timeout doesn't reliably cover a
stalled SSL handshake, so an intermittent network issue froze the entire
asyncio event loop for up to ~120s — blowing past the TUI/gateway's 15s
startup budget and showing "gateway startup timeout".
Run the check via asyncio.to_thread (off the loop) AND bound it with
asyncio.wait_for(timeout=_OSV_MALWARE_CHECK_TIMEOUT_S=12s). The malware check
is fail-open, so on timeout we log and proceed rather than blocking startup.

inline blocking call.

terminal_tool() resolves a per-task cwd override that WINS over config["cwd"]:
cwd = overrides.get("cwd") or config["cwd"]
config["cwd"] is sanitized for container backends in _get_env_config() (host
prefixes /Users//home//C:\\/C:/ and relative paths are replaced with the
backend default /root). But the override was applied RAW — it was never run
through that guard. The gateway/TUI registers the host launch dir as a cwd
override for workspace tracking (tui_gateway/server.py _register_session_cwd
-> _terminal_task_cwd -> _session_cwd -> os.getcwd()), so on a container
backend a host path leaked straight to `docker run -w <host-path>`:
- Windows desktop: -w C:\Users\<user> -> container fails to start (exit 125)
- POSIX: -w /home/<user> -> same
The ACP adapter translates its override cwd (acp_adapter/session.py
_translate_acp_cwd), but the gateway path did neither translation nor
sanitization, so the override bypassed the one guard that would have caught it.
Fix: extract the host/relative-path predicate into a shared
_is_unusable_container_cwd() helper (so the existing _get_env_config()
sanitizer and the new guard can't drift), and re-apply it to the *resolved*
cwd at the override-resolution site. Valid in-container override paths
(RL/benchmark sandboxes that set cwd to /workspace, /root, ...) are absolute
non-host paths and pass through untouched.
Tests: unit-pin the predicate (Windows backslash/forwardslash, POSIX home,
macOS /Users, relative, valid container paths) AND an E2E call-site pin that
drives terminal_tool() with a host-path override registered and asserts the
cwd reaching _create_environment is sanitized. Mutation-verified: reverting
the call-site guard makes the two host-path E2E tests fail (showing the raw
host path leaking) while the valid-/workspace-override test stays green.
Stabilize the long-running-tool heartbeat test by patching stale thresholds inside the test and asserting the heartbeat exceeds the idle ceiling, which preserves intent while removing scheduler-sensitive assumptions that flake in CI.
CI test shard has no PyPI egress: the real 'pip install packaging==20.9'
in test_core_package_is_not_shadowed failed (the pypi.org reachability
probe passed but the actual install didn't), failing slice 2/6.
- Prove the anti-shadow invariant deterministically: synthesize a fake
'packaging' in the durable target with a sentinel and assert the import
still resolves to the core copy (TestCoreNeverShadowed). No network.
- Cover the install wire offline: stub subprocess and assert --target +
--constraint are built in durable mode and absent in venv-scoped mode
(TestInstallArgConstruction).
- Gate the genuine PyPI install behind HERMES_RUN_NETWORK_TESTS=1 (opt-in,
skipped in CI) instead of a flaky reachability probe that doesn't predict
install success.
The published Docker image seals the agent venv (root-owned, read-only
/opt/hermes) and sets HERMES_DISABLE_LAZY_INSTALLS=1 so a runtime install
can't mutate and brick the core. But opt-in backends (Firecrawl web search,
Exa, Feishu, ...) deliberately keep their SDKs in tools/lazy_deps.py and out
of [all] (pyproject policy 2026-05-12: one quarantined release must not break
every install). The two policies collided: the SDK isn't baked in AND can't
lazy-install, so the default Firecrawl web_search/web_extract fail out of the
box in Docker (#51136), as do Exa (#49445) and Feishu (#50205).
Fix the whole class instead of baking in one backend: when
HERMES_LAZY_INSTALL_TARGET is set, lazy installs are redirected to a writable
dir on the durable /opt/data volume via `pip/uv install --target`, and that
dir is APPENDED to the end of sys.path. Because the core venv always wins
name collisions, a package installed this way can only ADD new modules — it
can never shadow, downgrade, or break a module the core ships. The worst a
bad/incompatible backend package can do is fail to import and report itself
unavailable; the agent core stays healthy. That structural guarantee is what
made it safe to seal the venv, and it is preserved here even with installs
re-enabled.
- tools/lazy_deps.py: durable-target mode — `--target` install + core-pinned
`--constraint` file (shared deps resolve to core's versions, conflicts fail
loudly at install time), append-only sys.path activation, ABI/Python-version
stamp that wipes the store if an image rebuild bumps the interpreter, and a
reworked gate so HERMES_DISABLE_LAZY_INSTALLS=1 redirects (rather than hard-
blocks) when a target is set. security.allow_lazy_installs=false still
disables installs in every mode.
- hermes_bootstrap.py: activate the durable target on sys.path at first import
(before any backend imports its SDK) so packages installed on a previous run
are importable on this run.
- Dockerfile: set HERMES_LAZY_INSTALL_TARGET=/opt/data/lazy-packages.
- docker/stage2-hook.sh: seed + chown the dir on the data volume.
- tests: real-install E2E proving installs land in the target, import cleanly,
don't leak into the sealed venv, and that a core package is never shadowed;
ABI-stamp wipe/preserve; gate matrix; Dockerfile/stage2 contract test.
Fixes#51136
When tempfile.mkdtemp() raises OSError (e.g. disk full), the exception
propagated past the try/finally block, so _mark_install_failed() was
never called. The 24h backoff marker never engaged, causing unbounded
retry on every command -- each attempt leaked a tirith-install-* temp
directory, eventually filling /tmp completely.
Fix: wrap mkdtemp in its own try/except OSError, returning
(None, "no_space") so the caller's normal failure path (including
_mark_install_failed) executes.

A single ddgs (DuckDuckGo) search could hang indefinitely and block the
shared agent loop — and therefore every platform (CLI, Telegram, Matrix...).
The DDGS constructor's timeout only bounds individual HTTP requests; ddgs's
multi-engine retry loop has no overall cap, so a slow/rate-limited response
could spin for 20+ minutes with no output and no error.
Run the synchronous ddgs call in a single-worker ThreadPoolExecutor and cap
it with future.result(timeout=_SEARCH_TIMEOUT_SECS=30). On timeout, return a
clear failure ("DuckDuckGo search timed out ... try a different provider")
instead of blocking; the pool is shut down with cancel_futures so a hung
worker is never awaited.
Salvaged from #37422 by @uzunkuyruk (authorship preserved). Re-applied on
current main (the PR's provider.py base had diverged). Added a load-bearing
timeout regression test (the original PR only updated the fake's constructor
and had no timeout-behavior test) — mutation-verified to fail without the cap.
Closes#36776.
_strip_blocked_tools used a hardcoded set missing 'cronjob'. Children
on gateway platforms could inherit the cronjob toolset, scheduling
persistent jobs that outlive the delegation despite DELEGATE_BLOCKED_TOOLS.
Fix: derive the strip set from DELEGATE_BLOCKED_TOOLS at runtime so the
two lists can never drift. Add 'cronjob' to DELEGATE_BLOCKED_TOOLS for
documentation consistency. Two regression tests lock the invariant.

The drift guard (introduced for #26045) correctly protects replace/remove
from clobbering un-roundtrippable content, but it also fires on the add
path. Since add only appends and never overwrites, the guard is
unnecessary and causes false positives when prior add() calls in the same
session shift the byte count of the on-disk file.
Add skip_drift parameter to _reload_target() and pass True from add().
Replace/remove continue to use the drift guard unchanged.

After `hermes update`, a globally-installed agent-browser's npm postinstall
(fixUnixSymlink) re-points the global symlink (e.g. /opt/homebrew/bin/agent-browser)
at our local node_modules binary. The next update wipes node_modules, leaving a
dangling symlink that `which` still reports but exec fails on with exit 127 —
silently breaking every browser tool (#48521).
Root cause is trust-on-presence: shutil.which/Path.exists accept a name that
resolves but won't run. Add hermes_constants.agent_browser_runnable() (resolves
the path + runs --version) and gate all four resolution sites on it:
_find_agent_browser now skips a dead candidate and falls through to the next
working one (extended PATH -> local .bin -> npx), self-healing the dangling link.
dep_ensure/doctor/nous_subscription validate too; doctor warns on a broken link.

job with origin=null, because those sessions never populate the
HERMES_SESSION_PLATFORM/CHAT_ID context vars that _origin_from_env reads.
The scheduler then resolves no delivery target and skips delivery — the
job runs and saves output to last_output, but nothing reaches the user
and they only find out by polling cronjob(action='list') (#51568).
This is by design (local sessions have no live-delivery channel), so the
fix surfaces it instead of silently dropping the intent:
- cronjob create now appends an informational notice to its result when
a created job resolves to zero delivery targets and the user did not
explicitly ask for deliver='local'. The check uses the scheduler's own
_resolve_delivery_targets so it accounts for origin, home channels,
'all', and explicit platform targets — no false positives.
- PLATFORM_HINTS gains a 'tui' entry (the TUI had none) and the 'cli'
hint now states that cron jobs from these sessions are local-only and
that deliver must target a gateway-connected platform to notify the
user. This stops the agent promising a delivery that never happens.
No scheduler/delivery behavior change; no new env var; cron isolation
invariant untouched.
Adds the #51579 regression test the issue asked for: run the real
docker_config_migrate.py boot path twice (host-reboot scenario under
--restart unless-stopped) and assert $HERMES_HOME/.env survives
byte-for-byte and the second boot is a no-op (no re-migration, no new
backup). Exercises real migrate_config + real file I/O via subprocess.
/reload-mcp -> shutdown_mcp_servers -> _kill_orphaned_mcp_children(include_active=True)
-> _send_signal -> killpg(pgid, SIGTERM). When a tracked MCP stdio child shares
the gateway's OWN process group, killpg delivers SIGTERM to the gateway itself,
firing its SIGTERM handler -> os._exit(0): /reload-mcp crashes the gateway.
Pre-compute the gateway's own pgid (os.getpgrp(), None on Windows/restricted)
and, in _send_signal, skip killpg when pgid == own pgid, falling through to the
per-pid os.kill path so the child is still reaped without self-signaling.
Adds a regression test (folded in) that pins the guard: with a tracked pgid
equal to the gateway's own pgid, killpg is never called for that pgid and the
per-pid kill fallback is used. Mutation-checked.

File tools (read_file, write_file, patch, list_directory, etc.) used
os.path.expanduser() which reads the gateway process HOME env var.
In Docker/systemd/s6 deployments where the gateway HOME differs from
interactive sessions, tilde expanded to the wrong directory.
Add _expand_tilde() helper that delegates to get_subprocess_home() when
available, falling back to os.path.expanduser(). Replace all 9
expanduser() call sites in file_tools.py with _expand_tilde().
Follow-up to the /memory approve fresh-store fix. Both the CLI fallback and
the messaging-gateway handler built a bare MemoryStore() with the hardcoded
default char limits (2200/1375), ignoring the user's configured
memory.memory_char_limit / user_char_limit. A live agent honors those
overrides (agent/agent_init.py), so an approval applied without a live agent
could accept a write the user's lower cap would reject, or vice versa.
Extract a shared tools.memory_tool.load_on_disk_store() factory that reads
the configured limits (falling back to defaults if config can't load) and
wire both the CLI and gateway handlers to it, closing the gap on both
surfaces and de-duplicating the construction block.
