📝 WalkthroughWalkthroughThis change set updates remote-control token resolution, MCP trust warnings, stream timing telemetry, background configuration, skill watching, session indexing, cron replay boundaries, and Anthropic model parsing. It also adds regression tests and release changesets. ChangesRemote Control authentication

Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to Print-mode trust warnings can render untrusted configuration values directly in terminals, potentially affecting terminal state. The change also exposes local storage paths in session-index logs and has incomplete release and replay-retention coverage; these issues should be resolved before merge.

Release the Node SDK behavior change.
Add @pymodel/node-sdk: patch to this changeset. getWorkspaceTrustInfo now returns different gatedMcpServers results for merged project and user MCP configurations.
As per coding guidelines, “Every PR that affects release artifacts (code, behavior, public API) must include a changeset.” Based on learnings, use patch unless a breaking change is confirmed.

Escape project-controlled values before writing the warning.
server.name and server.target come from the untrusted project MCP configuration. A control sequence in either value is written directly to stderr. This can modify terminal state or trigger terminal features such as clipboard operations.
Encode control characters before interpolation. Add a regression test with an ESC control character in a server name and target.

Do not log the storage path.
error.details['path'] is emitted as a log property. Storage paths can contain local home, workspace, or session identifiers. Remove this property and keep the warning generic.
As per coding guidelines: “never register user content, prompts, or file paths as properties.”
Suggested fix
- log?.warn('session index skips a non-directory entry', { path: error.details['path'] });
+ log?.warn('session index skips a non-directory entry');📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Remove the direct node:fs dependency.
UserFileSkillSource is business-domain code. It must not call existsSync directly. Use the filesystem Service that owns existence checks, or move the missing-root handling into the watch service.
As per coding guidelines: “Business code must not import 'node:fs'” and “Business domains do not implement persistence themselves — they depend on a Service that owns the access pattern.”

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Assert the full retained window.
The current assertions pass if replay retains only turn 15 and drops turns 16 through 19. That excludes turn 14 but does not retain the latest five turns. Assert the exact retained window, or at least the 10-record length and newest turn, in both tests.
Suggested test strengthening
const limited = limitAgentReplayByTurns(records, 5);
+ expect(limited).toHaveLength(10);
expect(JSON.stringify(limited)).toContain('cron fire 15');
+ expect(JSON.stringify(limited)).toContain('cron fire 19');
expect(JSON.stringify(limited)).not.toContain('cron fire 14');Apply the equivalent assertions to the cron_missed test.
As per path instructions, test assertions must be able to fail; these assertions do not detect an under-retained replay window. The PR objective requires retaining the latest five turns.

Problem
A batch of engine and CLI correctness gaps accumulated across the last upstream-equivalent surface: a crash on malformed model config entries, text streaming split by empty reasoning chunks, sessions missing from the session list when stray files sit in the sessions directory, unbounded resume replay for cron-heavy sessions, missing overrides for background/print configuration via environment, and no signal that print mode silently skips untrusted project MCP servers.
