Review follow-up. Two of the three items taken as written; the third declined
with a reason.
1. Taken. The reconcile semantics mean `patterns` may only ADD -- an entry left
out of it is not removed, because the on-disk list wins for anything this
process did not approve itself. Every caller in the tree is additive today,
so nothing breaks, but the signature does not say so. Stated in the
docstring, and pinned by
`test_a_caller_that_passes_a_smaller_set_does_not_remove` so a future
`allowlist remove` finds out here instead of in production.
NOT taken: the `reconcile: bool = True` opt-out. There is no caller that
wants it, and AGENTS.md:98-101 names exactly this -- "Speculative
infrastructure. Hooks, callbacks, or extension points with no concrete
consumer." The removal path is editing config.yaml, which the docstring now
says.
2. Taken. website/docs/user-guide/security.md, next to the existing
`hermes config edit` tip, which is where an operator reads about removing a
pattern: the list is read at startup, a pattern removed while a session is
running stays approved in that session until the next write or a restart,
and if it was removed for safety reasons, restart.
3. Taken. `test_save_failure_is_logged_not_raised` asserted non-raising but
never asserted the log its name promises. Now asserts
"Could not save allowlist" via caplog.
scripts/run_tests.sh tests/tools/test_permanent_allowlist_reconcile.py
=== Summary: 1 files, 9 tests passed, 0 failed (100% complete) in 0.4s
`load_permanent_allowlist()` runs exactly once, at module import
(tools/approval.py, the call at the bottom of the module), and
`load_permanent()` only unions into `_permanent_approved` (:2866-2869) --
nothing ever removes. `save_permanent_allowlist()` then wrote that in-memory
set straight back over `config["command_allowlist"]`, at eight call sites.
`command_allowlist` is a file the operator edits, and deleting a line from it
is the documented way to withdraw a standing approval. Any hand edit made
while a Hermes process is live was undone by that process's next `[a]lways`,
in both directions at once.
Reproduced on this tree with a temp HERMES_HOME:
BEFORE (tools/approval.py at fcbd107)
on disk before this process starts : ['git status', 'ls *']
operator edits config.yaml by hand : ['ls *', 'npm test']
(revoked 'git status', added 'npm test')
after ONE [a]lways : ['docker *', 'git status', 'ls *']
is_approved still honours revoked? : True
AFTER
after ONE [a]lways : ['docker *', 'ls *', 'npm test']
is_approved still honours revoked? : False
`npm test` was silently deleted from the operator's own config file, and
`git status` -- a standing approval they had just withdrawn -- was written
back and kept auto-approving. Neither prints anything.
The same shape loses writes between two live Hermes processes: whichever
saves second overwrites the other's entry.
The fix reconciles at write time. The file is re-read and the result is what
is on disk now, plus what this process approved since its own baseline, where
the baseline is what `command_allowlist` held the last time this process
synchronised with the file. That difference is what separates "the operator
granted this here" from "this was on disk at import and may since have been
revoked". Revoked entries are also dropped from `_permanent_approved` so
`is_approved()` stops honouring them for the rest of the process.
It does NOT make a revocation take effect the instant the file changes --
nothing re-reads the file on the approval hot path, and adding a stat there is
a separate change with its own cost. It makes the next write stop undoing the
operator's edit.
`_lock` is `threading.Lock` and not reentrant; all eight call sites were
checked and none holds it across the call, so the added critical section
cannot deadlock. The failure path still logs and returns rather than raising,
as before.
Searched open and merged PRs and issues for `command_allowlist revoke`,
`permanent allowlist reload`, `approval allowlist clobber` and
`save_permanent_allowlist` -- nothing covers this.
Tests: tests/tools/test_permanent_allowlist_reconcile.py, 8 cases -- both
halves of the bug, the two-process race, idempotence, the unedited round trip,
and the existing contract that a config write failure is logged rather than
raised.
scripts/run_tests.sh tests/tools/test_permanent_allowlist_reconcile.py
=== Summary: 1 files, 8 tests passed, 0 failed (100% complete) in 0.5s
No regression across the 29 test files in tests/ that touch the allowlist or
the approval module: 25 failed before and after, byte-identical failure set
(pre-existing missing-dependency failures in my local venv).
Under gateway.multiplex_profiles a secondary profile's turn ran with the LAUNCH
profile's working directory, command allowlist, redact_secrets switch, credential
file mounts, browser engine/headed flags, LSP service, auxiliary-provider health
marks and MCP stderr log, and several TERMINAL_ENV consumers read the process env
instead of the routed profile's terminal scope. A standalone `hermes -p X gateway
run` never behaved that way.
- tools/terminal_scope.py: resolve the terminal.cwd placeholder inside the
profile scope with the same rule gateway/run.py applies at import (local ->
$HOME, sandbox default otherwise) so the system prompt, context files and the
terminal of a routed turn start where the profile's standalone gateway would.
- tools/image_source.py, credential_files.py, image_generation_tool.py,
skills_tool.py, delegate_tool_progress.py, agent/tool_executor.py: read
TERMINAL_ENV / TERMINAL_CWD through the terminal scope.
- tools/approval.py (+ approval_floors.py): one permanent allowlist per routed
profile home; the unscoped module set stays for single-profile processes.
- agent/redact.py: `_redact_enabled()` resolves security.redact_secrets for the
routed profile (scope .env, then config); launch snapshot kept when unscoped.
- tools/credential_files.py, agent/auxiliary_health.py, agent/lsp/__init__.py,
tools/browser_tool_cloud.py, tools/mcp_tool_config.py,
tools/tool_result_storage.py: key process caches by profile home (or bypass
the slot under an override).

Fixes#104779
Co-authored-by: liuhao1024 <sunsky.lau@gmail.com>
Both shell-command guard entry points returned approval from the isolated-container fast
path before the operator's approvals.deny rules were evaluated, so a Docker sandbox with
no host mounts (or singularity/modal/daytona/vercel) skipped the entire user deny list.
The deny list is documented as never bypassable: it states what the agent may DO, not
what it can reach. Evaluate it before the container skip; the built-in dangerous-command
heuristics keep skipping there. hermes approvals test mirrors the new order.
Salvaged from #91029 by @fangliquanflq.
Every PLUGIN-COMPAT __getattr__ now calls hermes_cli.plugin_compat.warn_once(facade, name, target) before
resolving, emitting a HermesPluginCompatWarning (FutureWarning) once per process per name: old path, new
path, removal target. Importing a facade for its live API stays silent; only resolving a moved name warns.
COMPAT_MANIFEST.md documents the warning and how to silence it during migration.
Verified the runtime never routes through a pointer: every entry point (run_agent, cli, hermes_cli.main,
gateway.run, tui_gateway.server, web_server, model_tools + tool discovery, hermes_state, cron.scheduler,
browser_tool, mcp_tool, kanban, auth) imports clean and `hermes doctor` runs end to end with the warning
promoted to an error.
Also restores the check_compat_pointers CI step to .github/workflows/lint.yml, which a0be177aac dropped
when the compat layer was regenerated (the lint script itself was present; the workflow step was not).
hermes_cli/plugin_compat.py, tests/test_plugin_compat_warning.py and the two-line insert per facade are
part of the compat layer and go away with it.
The Sep 2026 decomposition (PR #102117) makes internal import paths a non-API: names now live in
the focused modules that define them. This commit is the ONLY thing keeping the old paths alive,
so external plugins have time to update. It is deliberately a single, unsquashed commit:
git revert <this sha>
removes every shim, stub and manifest at once on the announced date. Nothing in-tree may depend on
these pointers: scripts/check_compat_pointers.py (wired into lint.yml) fails CI if it does.
What it adds (see COMPAT_MANIFEST.md, compat_manifest.json):
- 332 facade modules get one delimited `PLUGIN-COMPAT` block appended at the end of the file
- 1,172 moved names resolved lazily via a module `__getattr__` (PEP 562) — never a top-level import,
so no import cycles; facades that already had `__getattr__` get a chained one
- 592 third-party/stdlib names the old modules used to expose, with their original import statements
- 266 public definitions that had been deleted as unused, restored byte-for-byte from the pre-decomposition
tree (+40 private helpers and 16 imports pulled in only because a restored definition needs them)
- 3 deleted modules recreated as re-export stubs (gateway/startup_watchdog, hermes_cli/observability/
relay_runtime, tools/environments/modal_utils)
- private names (`_x`) get no pointer: they were never API (3,792 skipped)
Verified: all 335 touched modules import under a fresh HERMES_HOME and every manifest name resolves;
the lint reports zero in-tree uses; ruff clean; targeted suites unchanged.
tools/approval.py no longer re-exports sibling names (approval_context/prompt/floors/detection/
human_wait/smart/gateway_wait); it imports only what it uses. Siblings reference sibling-defined
names directly (module-attribute reads on tools.approval_context so patching the defining module
still works); only facade-owned state (_lock, _gateway_queues, _permanent_approved, _denied,
_denial_breaker_addendum, _gateway_notify_cb) is still read back through tools.approval.
approval_detection calls its own _command_detection_variants instead of late-binding through the facade.
For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
Webhook sessions trigger the gateway approval branch because
HERMES_SESSION_PLATFORM is set, but the webhook adapter has no
send_exec_approval and no way to receive /approve replies. This
blocks the session for the full approval timeout (60-300 s) with
no human who can resolve it.
Fix: _is_gateway_approval_context() now returns False when the
session platform is 'webhook', falling through to the non-interactive
path (auto-approve with warning, or deny if cron).
Regression tests added for webhook, non-webhook gateway, cron, and
no-platform scenarios.
* feat(tools): session-persistent kernels for execute_code (kernel_mode: session)
execute_code spawns a fresh Python process per call, so every multi-step
data task re-loads its inputs: a CSV parsed in call one is gone by call
two, and scripts route state through temp files to survive. Hermes
already rewards programmatic tool calling (execute_code-only turns
refund the iteration budget), which makes the missing half — state that
survives between calls — the bottleneck.
Add opt-in `code_execution.kernel_mode: session`: one persistent kernel
per (task, mode, interpreter, cwd, tool-set). Variables, imports, and
loaded data persist across calls; `reset=true` discards state on demand.
The default `per-call` keeps today's behavior byte-for-byte.
Safety posture is unchanged by design: the child env comes from the same
builder as the per-call path (extracted, not duplicated, so the secret
scrubbing / PYTHONPATH hygiene cannot drift), the RPC server is the same
`_rpc_server_loop` with the same token and a per-cell tool budget, and
output passes the same ANSI strip + secret redaction. A timed-out or
interrupted cell kills the whole kernel tree and the next call respawns
— a wedged kernel can never hang the agent. The kernel env is frozen at
spawn; the schema and config comment say so.
Wire protocol: NDJSON requests on the kernel's stdin; responses framed
on stdout behind a per-kernel random sentinel, with unframed bytes
(fd-level output from user-spawned subprocesses) attributed to the
serialized current cell. The generated RPC client reconnects once when
HERMES_RPC_PERSISTENT=1, because a kernel legitimately outlives the RPC
server's 300s idle window between cells.
Tested on macOS 15 (Apple Silicon), Python 3.11: 13 new tests in
tests/tools/test_code_kernel.py (persistence, reset, error-keeps-kernel,
timeout-kills-kernel, sys.exit ends kernel, subprocess fd passthrough,
schema surface, mode fallback) plus the existing
test_code_execution.py / test_code_execution_modes.py suites (81 passed).
* fix(tools): session kernels get a stable owner, bounded lifetime, and per-cell RPC authority
Addresses the blocking review on the session-kernel design: two
authority/lifecycle boundaries were wrong.
1. Ownership and bounded lifetime. The kernel key's first component is
now the conversation's approval session key (_resolve_owner), not the
per-turn task id run_agent mints per top-level invocation — so state
genuinely survives across user turns of one conversation, and delegated
subagent sessions isolate naturally under their own keys (the task id
remains only the last-resort owner for embeds/tests with no session
context). Lifetime is bounded on four edges: kernels are disposed at the
same session boundary that clears the owner's approval/yolo state
(tools.approval.clear_session -> shutdown_kernels_for_owner), reaped
after code_execution.kernel_idle_timeout seconds idle (default 1800,
swept on every entry), capped process-wide at
code_execution.max_session_kernels live children (default 4, LRU
evicted), and still torn down by reset/death/atexit as before. The
ownership + disposal + idle-reap + cap shape deliberately carries
forward the lifecycle invariants of the earlier session-persistent
implementation in #88637 by @z80dev.
2. Per-cell RPC authority. The serving thread no longer freezes the
spawning cell's context/callbacks for the kernel's life. Each cell
installs a CellAuthority — captured on the calling thread exactly as
propagate_context_to_thread would for a per-call RPC thread — before its
request is written, and retires it on every settle path; _rpc_server_loop
gains a dispatch hook the kernel uses to route each tool call through
the CURRENT cell's context, callbacks, and task id. A call arriving with
no active cell is refused. Interpreter state persists; RPC authority
does not.
Composition with the per-script static guard (see the config note): a
persistent namespace lets cell N+1 invoke objects cell N created, which
a single-cell static scan cannot see — the runtime RPC boundary
(allow-list by name, per-cell budget, per-cell authority) is the
operative cross-cell enforcement in this mode, and the adversarial
alias test pins exactly that.
Tests (9 new): state survives across turns of one conversation;
sessions isolate; clear_session disposes the owner's kernels (and the
next turn starts fresh); the live-kernel cap LRU-evicts with evicted
children proven dead; idle kernels are reaped; a later cell's RPC runs
under that cell's approval callback; a cross-cell alias dispatches under
the CURRENT cell's authority; a settled cell's authority refuses
dispatch; each cell installs a fresh authority. 22/22 kernel tests, 81
code-execution tests, ruff clean. The 7 test-order failures in the
tools/-k-approval selection reproduce identically on the clean branch
base (pre-existing pollution, not this change).
* fix(code-kernel): delegated children get their own kernels — child contexts inherit the parent approval key, so qualify the owner with the delegation session id (live-verified leak, both directions)

The smart-approval guardian (`_smart_approve`) gates every flagged
terminal command with a synchronous auxiliary LLM call, but it never
passes `timeout=` and logs nothing on the normal path. In production a
stalled provider response silently froze the agent turn for 62 minutes
with zero log output; the gateway kill-switch eventually fired, and only
an unrelated error surfaced afterwards (#82846; watchdog-style fix in
#72500). The call was invisible by design — nothing logs at the hang
point.
Changes in tools/approval.py:
- Resolve the same configured timeout the client would use internally
(`auxiliary.approval.timeout` via `_get_task_timeout("approval")`) and
pass it explicitly to `call_llm`, so the deadline cannot be lost if the
internal default resolution changes or is misconfigured.
- Log the assessment call and its duration (DEBUG), and promote the
failure branch from DEBUG to WARNING with elapsed time + exception
class, so a wedged guardian call is visible in the logs instead of
silent.
- Failure still returns "escalate" (fail open to the human/pattern
gate) — behavior unchanged, observability only.
Complements #72500 (watchdog hard ceiling) rather than duplicating it:
explicit timeout is the root-cause hardening, logging closes the
silence gap; the watchdog remains the safety net if the SDK-level
timeout itself is defeated.
Tests: explicit timeout forwarded to call_llm (revert-fails), failure
logs WARNING + escalates. 49 approval-adjacent tests pass; one unrelated
test_approval.py failure is pre-existing (fails on clean main too).
Review round (#86412):
- the except-import fallback returned the RAW oversized value, re-opening
the exact macOS time_t overflow this fix prevents; it now fails closed
to a finite ~1-year cap matching agent.deadline.MAX_SAFE_TIMEOUT_S
- clamp engagement logs a WARNING so operators see the semantic change
- new tests: float-form oversized value (YAML 1e18), warning emission,
and the import-failure fail-closed path (blocked-import probe proving
the result stays Lock.acquire-safe)
Widen the salvaged gate-site clamp to the bug class. The gate min() from
the contributor PR capped the gate bound at 360s, which would break the
#79719 contract (gate must extend while a legitimate >360s approval
prompt is answerable) and left the sibling overflow sites live: the CLI
prompt thread.join, the gateway poll deadline, and human_wait_ceiling
all consume the same config value.
Clamp once in _get_approval_timeout() via agent.deadline.MAX_SAFE_TIMEOUT_S
(1 year - semantically unbounded, platform-safe). The gate keeps its
approvals.timeout-tracking behavior above 360s; 7 regression tests pin
lock-acquire/thread-join safety and the gate-extension contract.
Bilateral E2E: with approvals.timeout=1e20 in a real config.yaml, main
crashes every consumer with OverflowError; this branch survives all 5
probes.
#93392 was not just one pattern: every hardline rule with a bare \b anchor
fired on its token anywhere in the command line, including inside quoted
prose handed to echo, git commit -m, or gh --body. Anchor the
command-name-token rules and quote-mask the positionless ones:
- dd-to-block-device and kill -1 get the same _CMDPOS anchor as the
format/rm/shutdown families, keeping their argument tails.
- redirect-to-block-device and the fork bomb have no command-name token to
anchor (`>` appears mid-command; the bomb is a function definition), so
they now match a quote-masked variant (_mask_quoted_prose) where quoted
string content is blanked. $() and backtick spans inside double quotes
stay raw (the shell executes them), and any command whose command-position
words include a shell carrier (sh/bash/zsh/ksh/dash -c, eval, source, .)
is scanned unmasked -- quoting is not a bypass. bash/sh -c payloads also
still surface as raw detection variants via _execution_flag_findings.
Regression tests cover both directions for every touched pattern: quoted
prose passes, and every true-positive shape (bare, ; && | separators,
sudo/env prefix, $(), backticks, sh -c/bash -c/eval payloads) stays on the
unconditional floor.
mkfs was the only HARDLINE_PATTERNS entry without a _CMDPOS anchor, so
the unconditional floor blocked any command that merely mentioned the
token inside quoted prose — `echo "does this workflow use mkfs
anywhere?"` was refused outright (#93392) instead of running the echo.
Anchor mkfs to command position like every sibling entry (rm root-
delete, shutdown family, dd): it matches at the start of a command,
after separators, or behind sudo/env/exec/nohup/setsid wrappers, and
no longer fires on argument-position mentions. The quote-aware
_mark_command_starts pass already keeps separators inside quoted
strings from looking like command starts, and \b still protects
mkfs_helper-style names.
The gateway-lifecycle guards in cron/lifecycle_guard.py (Branch B, the
unconditional hard-block used by cron creation and the terminal tool when
_HERMES_GATEWAY=1) and tools/approval.py's launchctl rule both matched
`launchctl <verb> ... hermes[.-]?gateway` as a single sequential regex,
requiring the hermes-gateway label to appear literally AFTER the verb.
A shell command that builds the label earlier in the string — e.g. a
for-loop reading labels from a list defined before the actual launchctl
call — defeats that ordering entirely:
for item in 'ai.hermes.gateway-apollo:...' 'ai.hermes.gateway:...'; do
label=${item%%:*}; plist=${item#*:}
launchctl bootout "gui/$uid/$label"
launchctl bootstrap "gui/$uid" "$plist"
done
The literal text "hermes.gateway" only ever appears in the for-list,
never after "bootout" — so `[^\n]*\bhermes[.\-]?gateway` never matches at
the verb's position, even though the command unambiguously targets the
gateway's own launchd label.
cron/lifecycle_guard.py's verb list also didn't include `bootout` at all
(present in tools/approval.py's list and covered by its own test suite —
`launchctl bootout ai.hermes.gateway` is explicitly asserted as dangerous
there — so the omission in the sibling file looks like list drift between
the two guards rather than an intentional exclusion).
`bootout` is the verb that actually deregisters a launchd job (unlike
kickstart/stop, which just bounce a still-registered one), so a command
using it evades both guards, then removes the service from launchd with
no supervisor left to bring it back — worse than a simple restart-loop.
We hit this for real: a gateway self-restart (triggered from a chat
request to change the default model) used a raw terminal `launchctl
bootout`/`bootstrap` loop across 4 launchd labels instead of the normal
`hermes gateway restart` path. It slipped past both guards, self-bootout
killed the process mid-drain before its own follow-up bootstrap could
run, and all 4 gateway profiles ended up fully deregistered from launchd
with zero user approval (approvals.mode: manual was configured) until
someone manually re-bootstrapped them.
Fix: both guards now check "a launchctl lifecycle verb appears somewhere
AND a hermes-gateway label appears somewhere", independent of order, and
cron/lifecycle_guard.py's verb list gains bootout/kill/disable/remove to
match tools/approval.py's existing set. Internal recovery code
(hermes_cli/gateway.py's own `subprocess.run(["launchctl", "bootout",
...])` calls) is unaffected — these guards only scan shell-command
strings composed by the agent's terminal/cron tools, not the CLI's
trusted internal subprocess argument lists.
Adds regression tests in both test files reproducing the exact incident
command (label built in an earlier for-loop segment, referenced only via
`$label` at the point of the verb).

The hard block matched raw command text, but a shell resolves quote
splicing (`kick"start"`) and backslash escaping (`kick\start`) into the
literal verb before execution. So `launchctl kick"start" -k
gui/501/ai.hermes.gateway` ran exactly as the blocked `kickstart` form
while both the non-bypassable block and the approval detector missed it —
leaving an approval-bypassing gateway self-lifecycle operation reachable.
contains_gateway_lifecycle_command now runs a second pass over
shlex-tokenized command segments, where quotes and escapes are already
resolved. It stays anchored on a hermes-gateway identifier, so prose and
non-gateway hermes services are unaffected. Because this function is the
single choke point _contains_unsafe_gateway_action calls at every
recursion level, referenced-script and `sh -c` payload scanning inherit
the fix.
tools/approval.py had the same gap for quote splices: backslash escapes
are stripped by _normalize_command_for_detection, but quote splicing in an
ARGUMENT position is not touched by _deobfuscate_shell_word_for_detection
(scoped to command-position words, deliberately — widening it would let
quoted prose match the destructive patterns). It now delegates to the
fixed guard as a last check, so an ordinary pattern match still wins and
keeps its more specific reason string.
Tests: quoted, single-quoted and backslash-spliced verbs across the
launchctl/systemctl/hermes branches, the spliced gateway identifier
itself, a splice nested in an `sh -c` payload (resolves one level deeper,
asserted at the recursive entry point terminal_tool actually calls), plus
negative cases proving prose and non-gateway labels stay unblocked.
Verified on Windows: no regressions — the 10 remaining failures across
tests/tools/test_approval.py, tests/hermes_cli/test_gateway_restart_loop.py
and tests/cron are identical on the unmodified baseline (POSIX file modes,
symlink privileges, and /bin/bash script paths).

The protected agent-instruction gate grants one operation and persists
nothing, but only the TUI/desktop and Runs transports were taught that.
The prompt_toolkit panel, the input() fallback, and the ACP editor menu
still rendered "Allow for session", so a user editing SOUL.md tapped it,
got re-prompted on the next write, and read the gate as broken.
Thread allow_session through prompt_dangerous_approval so a caller that
re-asks every time collapses every surface to once/deny, and cover the
producer-to-transport contract end to end.
Three live findings from rc.4 staging, all on the relay-fronted Slack
path, all with the failure observed in live logs before the fix:
1. Approval-send timeout is AMBIGUOUS, not failed (no re-ask).
send_exec_approval through the connector can time out with the card
already rendered — the connector may ack after the deadline (slow
platform API call, transient backpressure, event-loop stall) — and
the timeout-as-failure path re-sent and produced duplicate cards.
The outcome is now tri-state: sent / failed / ambiguous. Ambiguous =
no re-send, no text fallback; the prompt registration stays armed so
a late tap still resolves. Only a definite send error falls back to
text.
2. pending_approval tool results forbid re-issuing the command.
With one card correctly armed, the agent could still mint a SECOND
card by re-running a rephrased variant of the gated command after
reading the pending_approval tool result (observed live: same
command re-issued in a different form, two cards). The tool message
now instructs: do not re-run/rephrase; wait or report pending.
Applied to both the terminal and execute_code arms.
3. Draft interim AND seal frames carry format_hints.
format_hints are stamped on send, edit, and send_for_platform, but
both draft-frame builders (send_draft interim + _seal_open_draft
seal) shipped bare metadata. A streamed final therefore arrived at
the connector hintless and sealed as a plain code block while
non-streamed sends rendered native markdown blocks (observed live:
language-tagged block on send/edit, downgrade on streamed seal).
Both sites now stamp _with_format_hints_for_chat
(destination-resolved, same pattern as the existing lanes).
Verified live after the fix against the platform's stored message
payload: rich_text_preformatted with language field on a streamed
seal.
Tests: tri-state outcome unit tests (5), draft/seal hint stamping + knobs-
off regression control (2, RED-first), existing format-hints suite intact
(14/14). Mutation-verified: reverting the adapter hunk sends
test_draft_interim_and_seal_frames_carry_hints red; restore -> green.
Boundary sweep (text egress lanes crossing the frame contract): send ✓
(pre-existing) edit ✓ (pre-existing) send_for_platform ✓ (pre-existing)
draft-interim ✓ (this PR) draft-seal ✓ (this PR); task_card lane carries
no text content — exempt.
Follow-up to the salvaged fix. Three parity gaps in the new CLI branch:
- Timeout arm dropped the denial-breaker addendum that the same function's
gateway arm and check_all_command_guards' CLI tail both append, so a
tripped breaker went unreported on a timeout.
- Human deny called _record_denial(), advancing a tally scoped to guardian
LLM DENY verdicts. Neither sibling CLI tail does this, so three
deliberate user denials escalated to breaker hard-stop text.
- The platform-marker half of the leak (HERMES_SESSION_PLATFORM set, no
HERMES_EXEC_ASK) was unpinned; it reaches the same branch.
Adds a platform-marker regression test plus two breaker-parity guards, and
clears the process-global _denial_tally in the shared fixture so a leaked
tally can't bleed the escalated addendum into unrelated assertions.
e37a0321eb fixed _run_approval_gate and check_all_command_guards: when
HERMES_EXEC_ASK (or a session platform marker) leaks into an interactive CLI
process with no gateway notify callback registered, those two functions now
prefer the registered CLI Dangerous Command panel over a silent
pending_approval nobody can see.
check_execute_code_guard — the whole-script gate for execute_code, a
separate function with its own copy of the same notify_cb-less
short-circuit — never got the same treatment. It doesn't even accept an
approval_callback parameter. In the same leaked-ask-mode-into-CLI scenario,
execute_code calls still silently drop into pending_approval with the panel
never shown, even though a CLI callback is registered.
Compute is_cli/approval_callback the same way the two fixed functions do,
and when _should_fall_through_to_cli_approval() says yes, run the same
hook-fire -> prompt_dangerous_approval -> hook-fire -> choice-branch
sequence _run_approval_gate's tail already uses, adapted to this function's
own message/persistence conventions (smart-denied session/permanent
suppression, denial-breaker addendum). Falls back to the existing
pending_approval behavior when no CLI callback is available.
Tests: 4 new cases in tests/tools/test_cli_approval_exec_ask_leak.py
mirroring the existing check_all_command_guards pair (approve/deny/timeout/
session-persistence). Mutation-verified: all 4 fail against the pre-fix code
and pass with it restored.
Neighbor suites: tests/tools/*approval* (291+ tests) and
tests/gateway/{test_approval_prompt_redaction,test_tui_approval_redaction,
test_plaintext_approval_routing,test_discord_exec_approval_content} +
tests/cli/test_cli_approval_ui.py all green. The 7 test_approval_mode_parity
/ test_nonrecursive_verification_artifact_cleanup failures seen in one full
batch run are pre-existing and independent of this change — confirmed by
re-running the identical batch with tools/approval.py stashed back to
pre-fix: the same 7 fail for the same reasons either way.
Note on an adjacent open PR: #65592 also touches check_execute_code_guard,
but an earlier, unrelated region of the function (adding an AST dangerous-
operation scanner to the "not is_gateway and not is_ask" auto-approve
branch). No semantic overlap with this fix's notify_cb-less branch; a small
rebase may be needed depending on merge order.
command_allowlist glob rules (e.g. 'cargo *') rejected any command whose
quoted arguments contained shell metacharacters — a cargo benchmark
regex filter like '^layer3/write/(a|b)$' disqualified the whole command
even though those characters are literal to the shell.
_has_allowlist_shell_operator is now quote-aware:
- metacharacters inside single/double quotes or behind a backslash are
treated as literal arguments;
- $ and backtick inside DOUBLE quotes still disqualify (expansion is
active there);
- quoted/escaped control characters still disqualify when the command
carries a -c/-e/--command/--eval-style option that hands the payload
to another interpreter (sh -c '...', git -c alias.x='!...' x);
- unterminated quotes disqualify (shape can't be reasoned about).
Compound commands (unquoted ; & | < > backtick $( newline) are rejected
exactly as before. hermes_cli/approvals_suggest.derive_glob picks up the
same semantics via its existing import.
Port from anomalyco/opencode#40869: parallel tool calls hitting the same
dangerous-command gate each enqueued their own _ApprovalEntry and fired
their own notify_cb — the user got N identical prompts and had to
/approve N times while the agent sat wedged.
_await_gateway_decision now detects an already-pending identical
approval (same command text + pattern-key set) in the session queue and
waits on the leader's event via _await_coalesced_leader instead of
re-prompting. Followers adopt session/always (persistence would auto-pass
a re-check anyway) and deny/timeout (re-asking a just-declined command is
prompt spam); a single-use 'once' makes the follower issue a fresh
prompt. Pre/post approval hooks fire with coalesced=True for followers.
