fix: bug-PR merge train batch 8 (CodeBuddy parallel tool-use, ci-privacy-gate hang) - #5945
Conversation
The macOS control batch stopped at the first aggregate-gate shell invocation and hit the 300s batch watchdog even though spawnSync specified 5s. Replace the synchronous call with an async spawn, ignored stdin, and an independent SIGKILL deadline that reports the child by name. Cover event-loop progress and the deadline path.

Merge Risk: 🟡 Moderate · up to The privacy-gate test may still hang when an aggregate-script subprocess outlives Bash. Resolve the descendant-process deadline behavior before merging. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The new handling improves isolation of parallel tool calls and checks bridge initialization earlier. One new completion path can still expose a tool call before its arguments are known to be complete; the effect depends on upstream behavior and client-side validation that could not be established.

This identifies the exact still-unfixed candidate (#5927) as having failed security review and records where its finding is being held, making it open security-triage metadata in the public devlog/. Remove this security-specific assessment from the tracked plan and retain it entirely in scratch space; a neutral statement that the PR was not carried can remain if necessary.

When the checked-in aggregate shell hangs inside one of its pipelines, killing only the direct bash PID leaves pipeline descendants holding the captured stdout/stderr descriptors. The promise rejects, but those live handles can still keep the Bun worker alive until the outer batch watchdog—the same hang this change is intended to eliminate. Spawn the shell in its own process group, terminate the whole group on deadline, and wait for closure before rejecting.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Terminate the aggregate child’s process tree at the deadline.
If the workflow script hangs in a subprocess such as jq, child.kill("SIGKILL") terminates Bash but does not necessarily terminate that subprocess. The subprocess can retain the captured stdout or stderr pipe. The promise then rejects, but the test runner can remain alive after the five-second deadline. The new deadline test uses only a Bash built-in loop, so it does not exercise this case. Start Bash in a separate process group and terminate the group on POSIX runners. Add a deadline test with a child process that inherits the output pipes. (bun.sh)

…l tracking The lidge-jun#5945 change on dev replaced the coding-agent parse state single open-call slot (`openToolCallId`) with per-block buffering (`openToolBlocks`, `toolBlockStarts`), so a tool_use block is emitted when it closes rather than when it starts. The adapter completeness invariants compared the starts it had already emitted against the completed count. Under the new state those two are equal by construction, so a block that opened and never closed became invisible and the turn ended as a successful text completion instead of failing closed. That is the regression the existing test, "a result that arrives while a captured call is still open fails closed", caught on the rebase. Both call sites now read `toolBlockStarts` against `completedToolCalls`, the same pair the sibling CodeBuddy turn reads, and the state initializer matches that turn as well. A second test pins the parallel batch the invariant depends on: two calls on one reused block index arrive as two complete calls, in order.

38d1668b43: the tool-bridge init check now runs when a tool-use start frame arrives. Before, it ran when a buffered call closed, so astart → init → stopsequence produceddone(tool_use)instead oftool_bridge_init_missing.c6b9a73b65: with more than one tool block open, an argument delta without an index now fails the turn. Before, it was dropped, and both calls could still close as a successful tool-use turn with altered arguments. An indexless delta with a single open block still goes to that block.CI: the
