The inline-shell trust gate matched only the exact install dir from the
active profile's hub lock, and a lock read failure fell through to
expansion. So a nested SKILL.md inside a --force community bundle, the
same skill viewed by another profile through skills.external_dirs, and
any skill under a truncated or wrong-shape lock all ran their !`cmd`
snippets on view. Match descendants of community install dirs, also read
the lock that owns the skills tree the dir lives in, and fail closed when
an existing lock cannot be read.
Inline `!`cmd`` expansion in SKILL.md bodies ran for every skill whenever the
global skills.inline_shell flag was on — a community hub skill and a builtin
were expanded identically. The hub's install gate (INSTALL_POLICY) blocks a
community install on the caution/dangerous verdicts the inline-shell DSL scans
as, but --force or a pre-scanner install puts that skill on disk anyway, and
the next view/slash/preload would auto-execute it on the host.
Gate expansion at the single preprocess_skill_content choke point (all three
surfaces route through it): community-trust hub lock entries never expand;
trusted/builtin hub entries and anything without a hub lock entry (bundled-
synced, user-created, project/external) keep the flag's contract. Lock read
failures skip the gate, like every other provenance consumer.
Fixes#63307
- salvage summary cap and _bound_oversized_record still composed bare
truncation idioms in model-visible text; route them through elide /
elide_middle so a copied marker is guard-visible.
- the active-task line repr()'d the elided text, escaping the marker's
apostrophe when the user text held both quote kinds and hiding it from
the guard; elide after repr instead (text within the cap stays whole).
- a leftover budget smaller than the marker produced a content-free,
over-budget marker line in _build_verbatim_user_section and the Slack
nested-attachment path; skip the item instead.
- _build_verbatim_user_section elided twice, reporting the wrong total;
one elide at min(cap, remaining).
- drop redundant len() pre-checks before elide() and name verification
stop's repeated 1200.

The #83714 fix hardened only the tool-call args renderer; five other
renderers (plus three same-idiom siblings) still composed the bare
truncation marker, which the model imitated from replayed context into
new durable writes (#83435).
This routes all model-visible elision in agent/ through shared helpers
in agent/compression_marker.py:
- elide(text, limit): head + marker cap with accurate omitted/total counts
- elide_middle(text, head, tail): kept head/tail with the middle elided
The elision marker's first sentence is byte-identical to the args marker's,
so the existing _COMPRESSION_MARKER_RE (and the dispatch-boundary guard in
tool_dispatch_helpers) rejects a copied marker regardless of which renderer
leaked it; only the tool-call-specific second sentence is dropped so the
marker still fits small caps (the clarify summary cap is 199 chars).
Routed sites:
- context_compressor.py: static-fallback turn renderer, _sum_clarify(),
summarizer prompt builder (middle elision), active-task snapshot,
lean user-message quotes (2 sites)
- skill_preprocessing.py: inline-shell output embedded into skill bodies
- lsp/reporter.py: truncate() for <diagnostics> tool output
- verification_stop.py: verify-on-stop nudge output summary
Regression test asserts the imitable idiom appears nowhere in agent/
strings (comments excluded), so a new open-coded renderer cannot land
silently.
Fixes#121548
(cherry picked from commit 69c63d50b4ababedf4fb4ff88c08f5d1e144a79f)
CreateProcess resolves a bare "bash" to System32 WSL launcher before PATH,
and shutil.which("bash") inherits PATH order (#115124), so node bootstrap,
the TUI node probe and webhook filter scripts ran the wrong interpreter on
Windows. All four sites now use tools.environments.local._find_bash (Git Bash
first, probed). rc!=0 with no output at all is now a WARNING in webhook
filters and an explicit [inline-shell exit N with no output] marker in skills.

Carry the existing write fence across Hermes-owned spawn boundaries without
dropping board routing or changing credential policy. Grant dispatcher and
managed tool runtimes explicit task scope; align CLI task mutations with tools.
Verify real shell/CLI descendants, dispatcher startup, and supervised stdio
transport against isolated SQLite boards. This is cooperative runtime scoping,
not OS confinement.

Salvaged from #56085 (@Stoltemberg), rebased onto current main: sites
main had already converted (credential_pool, auxiliary_client MoA
paths, model_metadata, moa_loop, agent_runtime_helpers) resolve to
main's versions; the remaining ~29 read-only sites across 16 agent/
files swap to the no-deepcopy readonly loader (~135us saved per call).
Full per-site mutation audit performed (every enclosing function read,
escapes traced): 23 SAFE, 5 ESCAPES with read-only consumers, 1 UNSAFE
path (init_agent -> get_compatible_custom_providers -> normalizer
in-place alias writes) fixed by the preceding no-mutate commits, which
make the normalizer copy-safe for ALL callers.
On Windows with Chinese locale (GBK), subprocess.run(text=True) without
explicit encoding causes UnicodeDecodeError crashes. This fix adds
encoding='utf-8', errors='replace' to all subprocess.run() and
subprocess.Popen() calls that use text=True across 76 non-test Python files.
Fixes#53428 (master tracker for Windows GBK locale crash).
Note: credential_pool.py and electron changes excluded per reviewer request —
those will be submitted as separate focused PRs.
The Windows desktop GUI runs its backend headless via pythonw.exe. Several
auxiliary subprocess sites that run inside that windowless backend spawned
console-subsystem children (git, gh, wmic, powershell, bash, rg, taskkill)
WITHOUT CREATE_NO_WINDOW, so Windows allocated a fresh conhost per call and
flashed a black window on screen — sometimes continuously (the dashboard
Projects-tree git probe alone fired ~118 spawns in 60s on startup).
The terminal tool, cron, browser, code_execution, and gateway-spawn paths
already carry windows_hide_flags(); these auxiliary probe/scan/launcher legs
were missed. Wire the existing helper into them:
- tui_gateway/git_probe.py: run_git (+ encoding=utf-8/errors=replace, fixes the
cp950 UnicodeDecodeError on CJK paths from the same site)
- agent/coding_context.py: _git (per-turn git status/log/diff)
- agent/context_references.py: _run_git + _rg_files (@file/@ref resolution)
- hermes_cli/copilot_auth.py: gh auth token probe (auxiliary provider:auto)
- hermes_cli/gateway.py: wmic + PowerShell Get-CimInstance PID scan
- hermes_cli/main.py: wmic stale-dashboard PID scan
- gateway/status.py: taskkill /T /F force-kill
windows_hide_flags() returns 0 on POSIX, so every changed call is a no-op on
Linux/macOS (verified: real git/rg probes still work; Windows-simulated calls
all pass creationflags=CREATE_NO_WINDOW).
Scoped to the windowless-backend paths that cause the reported flashing. The
Electron updater-handoff leg (main.cjs windowsHide:false) and the
interactive-CLI banner probes (cli.py) are intentionally NOT touched here —
the former needs a Windows-tested change of its own, the latter runs in a
visible console anyway.
Tracking: #54220

When Hermes runs in TUI mode, the gateway child process communicates with
the Node.js parent over a JSON-RPC protocol on stdin. Subprocess calls that
inherit this stdin fd can trigger a race condition where the child's stdin
read returns EOF, causing the gateway to exit cleanly (exit code 0) mid-tool-
execution.
This is the same root cause as issue #14036 (byterover plugin) and PR #39257
(SSH environment backend). This commit applies the fix — stdin=subprocess.DEVNULL
— to all 85 subprocess.run() and subprocess.Popen() calls that execute inside
the TUI gateway child process.
Scope: TUI-context code only (agent/, tools/, plugins/, tui_gateway/server.py).
CLI code (cli.py, hermes_cli/), tests, scripts, and gateway process management
are excluded — they don't run inside the TUI child and inherit the terminal's
stdin, not the JSON-RPC pipe.
85 call sites across 28 files. All files pass syntax check.
