Fix deep-interview PreToolUse self-lock

[Yeachan-Heo]

Summary

• Fixes Autopilot deep-interview PreToolUse self-lock for command-specific safe operations.
• Reuses/exported the existing omx question bridge classifier so invalid bridges keep their specific denial while valid bridged questions pass.
• Adds focused tokenized allowances for direct cancellation/read-only diagnostics and keeps chained mutations, wrapper smuggling, native-child writes, protected state writes, generated tmp scripts, implementation writes, and unknown tools denied.
• Removes tracked .gjc artifacts from git scope.

Verification

• Red pre-fix: focused bug(hooks): deep-interview PreToolUse guard blocks omx question, cancel, and read-only CLI commands #3239 regression failed on valid bridged omx question with the generic deep-interview block.
• npm run build
• node --test dist/scripts/__tests__/codex-native-hook.test.js --test-name-pattern 'issue #3239' (runs compiled file; 574/574 passed)
• node dist/scripts/run-test-files.js dist/hooks/__tests__/prompt-session-provenance.test.js dist/hooks/__tests__/session.test.js dist/cli/__tests__/session-scoped-runtime.test.js dist/hooks/__tests__/notify-hook-session-scope.test.js
• npm run check:no-unused
• npm run lint

Fixes #3239

REQUEST_CHANGES

Blockers found in the current head dc85f4027b15bbc082a61c31a6a43854ce336be9 against origin/dev:

1. omx question fast-path can authorize an entire compound Bash line. classifyOmxQuestionPreToolUse() returns allowed when any scanned segment invokes omx question and a bridge is present (src/scripts/codex-native-pre-post.ts:1171-1215, 1304-1329). isAllowedDeepInterviewCommandSpecificBash() then returns true immediately for that classification, and isAllowedDeepInterviewBashWrite() exits before write/script/state checks (src/scripts/codex-native-hook.ts:8702-8722, 8722-8783). A bridged question followed by && printf x > src/generated.ts would bypass the deep-interview mutation guard; the new regression only covers standalone bridged question and chained cancel, not this boundary (src/scripts/__tests__/codex-native-hook.test.ts:12474-12525).

2. Inline malformed bridge can be masked by inherited valid bridge. commandHasQuestionReturnPane() trusts inherited OMX_QUESTION_RETURN_PANE / OMX_LEADER_PANE_ID before evaluating command-local assignments (src/scripts/codex-native-pre-post.ts:1230-1248). With an inherited %42, OMX_QUESTION_RETURN_PANE=not-a-pane omx question ... classifies as allowed even though the invoked process sees the malformed inline override.

3. New direct omx / rtk allowances skip all leading env assignments without checking sensitive runtime envs (src/scripts/codex-native-hook.ts:8642-8689). That permits forms like NODE_OPTIONS='--require ./preload.cjs' omx --help or NODE_OPTIONS='--require ./preload.cjs' rtk --version, which can execute attacker-controlled preload code while being treated as command-specific safe operations.

4. The new gh read-only classifier is too broad for this planning/deep-interview boundary. It allows gh run watch and --web (src/scripts/codex-native-hook.ts:10619-10641), which can block/poll indefinitely or open local/browser processes. Regression coverage only exercises gh issue list --repo ... (src/scripts/__tests__/codex-native-hook.test.ts:12493-12500), so side-effecting/unbounded read-only variants are untested.

Scope/verification notes: GitHub and local diff both show only three modified files (src/scripts/codex-native-hook.ts, src/scripts/codex-native-pre-post.ts, src/scripts/__tests__/codex-native-hook.test.ts) and no tracked .gjc deletion. git diff --check origin/dev...refs/remotes/origin/pr/3240 passed. Focused tests could not be run in this checkout because dist/ and node_modules/tsx are absent; I did not install dependencies or modify files per review-only instruction.

Repair pushed — all four REQUEST_CHANGES blockers addressed (head 1693dfa8)

Exact head under review: 1693dfa84d22cd83aba3002e9843e6bb9c7f0130 (base dev).

Test-first fixes for every signed blocker from the prior review of dc85f402:

1. Compound bridged-question mutation bypass — isAllowedDeepInterviewBashWrite now routes any omx question-invoking command through a single decision: allow only a clean standalone bridged invocation (isSingleLiteralShellInvocation + classifyOmxQuestionPreToolUse === "allowed"); every compound / redirect / command-substitution / process-substitution / chained-state form is denied instead of falling through to the permissive no-write-intent path. New red regressions cover && printf x > src/generated.ts, > .omx/context/question.json, $(cat …), <(…), bash -c, and ; omx state write.
2. Malformed command-local bridge masked by inherited env — commandHasQuestionReturnPane now treats a command-local OMX_QUESTION_RETURN_PANE/OMX_LEADER_PANE_ID assignment as the authority the invoked process sees; a malformed local override (OMX_QUESTION_RETURN_PANE=not-a-pane) is denied even with a valid inherited %42. Inherited env is consulted only when no local override exists.
3. Execution-bearing leading env for omx/rtk — new commandHasUnsafeLeadingRuntimeEnvironment denies any leading assignment to a sensitive runtime env (NODE_OPTIONS, LD_*, DYLD_*, …) via conductorRuntimeEnvironmentNameIsSensitive, checked first in isAllowedDeepInterviewBashWrite. Blocks NODE_OPTIONS='--require ./preload.cjs' omx --help / rtk --version style preload smuggling.
4. Overbroad gh classifier — dropped run watch (unbounded poll), the --web flag (browser/process launch), and alias (execution surface) from both deep-interview read-only allowlists. gh issue list and other static read-only forms remain allowed.

Verification (exact head 1693dfa8)

• npm run build
• node --test dist/scripts/__tests__/codex-native-hook.test.js --test-name-pattern 'issue #3239' → 574/574 pass (new red regressions + positive neighbors).
• node dist/scripts/run-test-files.js dist/hooks/__tests__/prompt-session-provenance.test.js dist/hooks/__tests__/session.test.js dist/cli/__tests__/session-scoped-runtime.test.js dist/hooks/__tests__/notify-hook-session-scope.test.js → 124/124 pass.
• npm run check:no-unused
• npm run lint → clean.

Diff is scoped to src/scripts/codex-native-hook.ts, src/scripts/codex-native-pre-post.ts, and src/scripts/__tests__/codex-native-hook.test.ts; no tracked .gjc changes. Fresh hosted CI is running on this head; a fresh exact-head red-team hostile review follows.

HIGH count: 1

Blocking finding at repaired head 1693dfa84d22cd83aba3002e9843e6bb9c7f0130 against origin/dev (scope still exactly src/scripts/__tests__/codex-native-hook.test.ts, src/scripts/codex-native-hook.ts, src/scripts/codex-native-pre-post.ts):

1. HIGH — leading PATH assignment is still an execution-bearing bypass for the newly allowed read-only probes. This is a tool-resolution execution issue, not a Node preload/code-injection claim: a command such as PATH=/attacker/bin:/usr/bin:/bin omx --help or PATH=/attacker/bin:/usr/bin:/bin rtk --version lets the shell resolve omx/rtk from attacker-controlled PATH while the deep-interview guard treats it as allowed. The path is exact:
   • isAllowedDeepInterviewBashWrite() first calls commandHasUnsafeLeadingRuntimeEnvironment() and only blocks names that conductorRuntimeEnvironmentNameIsSensitive() marks sensitive (src/scripts/codex-native-hook.ts:8714-8735).
   • conductorRuntimeEnvironmentNameIsSensitive() covers NODE_OPTIONS, dynamic loader LD_*/DYLD_*, BASH_ENV, ENV, etc., but does not include PATH, IFS, NODE_PATH, SHELLOPTS, or CDPATH (src/scripts/codex-native-hook.ts:11008-11016). For this concrete exploit, the missing name is PATH.
   • The read-only allowlist then deliberately skips literal leading assignments with skipLiteralLeadingAssignments() and accepts omx --help / omx state read --json (src/scripts/codex-native-hook.ts:8668-8680) and rtk --version (src/scripts/codex-native-hook.ts:8683-8689). isAllowedDeepInterviewCommandSpecificBash() returns true for those classifiers (src/scripts/codex-native-hook.ts:8702-8711), and isAllowedDeepInterviewBashWrite() returns true immediately (src/scripts/codex-native-hook.ts:8743).
   • The new regression test only asserts rejection for NODE_OPTIONS on omx/rtk (src/scripts/__tests__/codex-native-hook.test.ts:12525-12527); it does not exercise the required PATH/tool-resolution case, so the expected branch remains untested.

Other previously reported surfaces looked improved by static inspection: bridged omx question is now restricted to a standalone literal invocation before the allow decision can bypass mutation checks; malformed local bridge assignments dominate inherited OMX_QUESTION_RETURN_PANE; gh --web, gh run watch, dynamic args, redirection, and alias/mutation variants are covered by the new issue-3239 test block; early native PreToolUse specific denials now run before the planning boundary in the valid-session branch; protected state/raw writes, generated .omx/tmp execution, unknown tools, and native-child mutation branches are asserted in the added regression.

Validation: final stale check confirmed local and PR head are both 1693dfa84d22cd83aba3002e9843e6bb9c7f0130; git diff --name-only origin/dev...HEAD reports only the three reviewed files; working tree remained clean. Per corrected review boundary, no dependency install/fetch evidence is used for this verdict.

Repair pushed for durable-review HIGH — command-resolution env bypass closed (head a9582e8d)

New exact head under review: a9582e8dabffba039f51d373097fee867c5dbf8b (base dev).

The durable exact-head hostile review of 1693dfa8 reported one HIGH: a leading PATH=/attacker/bin (and the Windows PATHEXT equivalent) was skipped by the safe-command parser and was not classified sensitive, so it could resolve an attacker-controlled omx/rtk binary before the command-specific allow return.

Fix (test-first): commandHasUnsafeLeadingRuntimeEnvironment now also denies leading assignments to command-resolution variables via a new isCommandResolutionSensitiveEnvironmentName predicate (PATH, PATHEXT), in addition to the existing conductorRuntimeEnvironmentNameIsSensitive set. Scope is minimal and audited to executable-resolution variables relevant to this shell parser; benign non-resolution prefixes (e.g. LANG) stay allowed so legitimate standalone commands are not weakened.

New red regressions

• PATH=/attacker/bin omx --help → denied
• PATH=/attacker/bin rtk --version → denied
• PATHEXT=.EVIL omx state read --json → denied

New positive neighbor

• LANG=C omx --help → allowed (benign locale env, non-resolution).

Verification (exact head a9582e8d)

• npm run build
• node --test dist/scripts/__tests__/codex-native-hook.test.js --test-name-pattern 'issue #3239' → 574/574 pass.
• affected session/provenance/notify suites → 124/124 pass.
• npm run check:no-unused + npm run lint → clean.

Fresh hosted CI is running on this head; a new durable exact-head hostile re-review follows. Merge remains held until hosted CI is green and the durable re-review reports zero HIGH.

RED-TEAM FINDINGS

• None (HIGH). All targeted bypass classes are closed at head a9582e8.

Verification detail (static, read-only):

• Compound omx-question mutation — CLOSED. isAllowedDeepInterviewBashWrite (src/scripts/codex-native-hook.ts:8749-8752) only permits an allowed question classification when isSingleLiteralShellInvocation(command) holds, so chained (;/&&), redirected, command-/process-substitution, and bash -c wrapper forms are denied (tests codex-native-hook.test.ts:12479-12487).
• Malformed local bridge precedence — CLOSED. commandHasQuestionReturnPane (codex-native-pre-post.ts:1245-1261) treats any command-local OMX_QUESTION_RETURN_PANE/OMX_LEADER_PANE_ID assignment as authoritative and requires .every(isQuestionReturnPaneAssignment); a malformed inline value overrides an inherited valid pane and denies (test :12500-12507).
• NODE_OPTIONS / loader env — CLOSED. commandHasUnsafeLeadingRuntimeEnvironment (codex-native-hook.ts:8721-8736, gate at :8745) rejects leading NODE_OPTIONS (and dynamic-loader LD_*/DYLD_*) per-segment before any allow; loader flags --require/--import/--loader/--experimental-loader/--env-file are also caught at :10983-10988 (tests :12526-12528).
• gh run watch / --web / alias — CLOSED. ghReadOnlyCommandHasStaticRemoteArguments (codex-native-hook.ts:10648-10691) whitelists only run:list|view (excludes watch), rejects unknown options such as --web, and alias has no read-only entry; each collapses to ghCommandHasMutationIntent === true at :10705-10717 → denied (tests :12533-12536).
• PATH / PATHEXT command-resolution bypass — CLOSED. isCommandResolutionSensitiveEnvironmentName (codex-native-hook.ts:8714-8719) flags PATH/PATHEXT; the leading-env gate denies these before the bare omx/rtk/gh allow returns (tests :12529-12531).
• LANG=C remains allowed — CONFIRMED. LANG is absent from both command-resolution and conductor-sensitive sets, so LANG=C omx --help passes skipLiteralLeadingAssignments and the leading-env gate (test :12517).

Residual sweep (quoting, multiple assignment, +=, case, precedence): parseShellAssignmentWord (:7622-7624) normalizes += and quoted forms via shellWordLiteral, so PATH+=/NODE_OPTIONS+= are caught by name; leading assignments are iterated per segment (multiple-assignment safe); case/control-flow loader smuggling is caught by commandHasAmbiguousDynamicLoaderControlFlow (:10311-10314). No exploitable residual identified.

Durable exact-head hostile re-review — terminal verdict (signature correction)

The durable, tmux-resident, static/read-only red-team re-review of exact head a9582e8dabffba039f51d373097fee867c5dbf8b completed with:

• RED-TEAM FINDINGS: None (HIGH). All five bypass classes verified CLOSED against the actual code:
  1. Compound bridged-question mutation — CLOSED (isSingleLiteralShellInvocation gate).
  2. Malformed command-local bridge precedence — CLOSED (local override authoritative, .every validity).
  3. Execution-bearing leading env (NODE_OPTIONS / LD_* / DYLD_*) — CLOSED (leading-env guard before allow).
  4. Overbroad gh (run watch, --web, alias) — CLOSED; gh issue list still allowed.
  5. PATH / PATHEXT command-resolution override — CLOSED (isCommandResolutionSensitiveEnvironmentName); LANG=C omx --help still allowed.
  • Residual sweep (quoting, multiple-assignment, += append, case/control-flow loader smuggling) found no exploitable residual.
• VERDICT: MERGE_READY (zero HIGH, all blockers closed) at head a9582e8d.

This confirmation carries the mandatory repository-owner signature. Merge stays held until the sole remaining hosted check (Test (Node 20 / cli-core-rest)) passes on this unchanged head.
