[4.2.0] - 2026-05-16

Release tag: v4.2.0.

Added

• prompt-async-gate: new shared safety primitive (src/shared/prompt-async-gate.ts) with promptAsyncAfterSessionIdle, promptAfterSessionIdle, releasePromptAsyncReservation, DEFAULT_PROMPT_ASYNC_POST_DISPATCH_HOLD_MS public exports. Routes 13+ internal hook callers through reservation-based duplicate-injection prevention. See docs/reference/prompt-async-gate-rfc.md.
• Background-agent: extracted ParentWakeNotifier module for parent-wake coalescing (preparatory refactor; manager.ts integration in same release).
• First-prompt watchdog for stuck subagents (closes #3952 by way of #4051).
• Subagent quota abort fast-path when no fallback is configured (closes #4006).

Fixed

• prompt-async-gate: add dispatch timeout via Promise.race, fix post-dispatch reservation hold on throw, harden prefix release to require : suffix (BLOCKER-1, BLOCKER-2, HIGH-6, HIGH-7 partial).
• model-suggestion-retry: release reservation before suggested-model retry attempt (regression caused by post-dispatch hold landing).
• prompt-async-gate tests: remove fixed-time sleep synchronization from the BLOCKER-3 path. The final release branch should keep only event-driven test synchronization for this area.
• session-recovery: schema-compatible synthetic tool results (PR #4053 supersedes #3866).
• tool-pair-validator: schema-compatible synthetic results for background sessions (PR #4032).
• claude-code-hooks: accumulate modifiedInput on allow/deny/ask exit paths (PR #3299 area, multiple commits).
• runtime-fallback: dedupe overlapping continuations, preserve provider-specific retries, classify localized provider errors.
• team-mode: skip tmux layout when opencode server unreachable (closes #3894).
• delegate-task: honor user fallback_models when category primary is unreachable.
• background-agent: detect stalled active sessions, coalesce rapid idle parent notifications, retry transient missing output tasks.
• todo-continuation: remove activity-based stagnation bypass, clean up idle event diagnostics.
• AGENTS.md: strengthened prompt-injection danger warning with root-cause analysis, gate semantics, forbidden patterns, and required tests.

Changed

• TypeScript audit: prompt-async-route-audit migrated from regex to TypeScript AST walker, catching destructuring, bracket call, optional chaining, and type-cast aliased bypass patterns (HIGH-5).
• Public surface: createPluginModule test seam moved from src/index.ts to src/testing/create-plugin-module.ts (HIGH-8). Plugin default export pluginModule is unchanged.
• CI: removed sharded test runner; now uses plain bun test in a single process (test-discipline.md added to enforce no-setTimeout-in-tests).
• Background-agent: manager.ts internal parent-wake state delegated to ParentWakeNotifier (HIGH-9).

Known Issues

• BLOCKER-4: Delegated child-session early-failure fallback (PR #3825 reverted). Delegated subagents that fail on the very first promptAsync may not advance to fallback models. See docs/reference/known-issues.md. Reland targets v4.2.1.

Internal

• New .sisyphus/rules/test-discipline.md rule: forbids setTimeout(resolve, N) and await sleep(N) in test bodies unless time itself is the SUT.
• mock.module lifecycle audit test (src/shared/mock-module-lifecycle-audit.test.ts) added to catch unpaired mocks (H10).
• Public exports for prompt-async-gate primitives - MINOR semver bump justified.
• If parallel BLOCKER-3, HIGH-9, or BLOCKER-4 follow-up commits land after this entry, update the changelog in the final release commit with their exact hashes.
