Provider-managed environments should preserve Claude attribution only when the selected model is actually Claude-prefixed. Non-Claude provider models now disable the attribution header so third-party providers do not inherit Claude-specific prompt metadata.
Constraint: Claude model detection is intentionally model-name based to match the requested provider policy.
Rejected: Remove attribution headers globally | official Claude-prefixed models should keep existing behavior.
Confidence: high
Scope-risk: moderate
Directive: Do not broaden this policy without live provider request-shape verification.
Tested: Targeted server, provider, settings, cron, and managed-env tests in prior verification pass.
Not-tested: Full verify gate after this commit.
Desktop launches can inherit a sparse GUI environment, while user runtimes such as nvm and Homebrew are often initialized from shell startup files. Capture a bounded login+interactive shell environment once and reuse it for desktop CLI sessions, scheduled tasks, and MCP stdio startup while keeping explicit MCP PATH and provider-managed env overrides authoritative.
Constraint: macOS app launches may omit user shell PATH and exported runtime variables
Rejected: Patch only MCP stdio | leaves normal desktop sessions and scheduled tasks inconsistent
Confidence: high
Scope-risk: moderate
Directive: Keep provider/OAuth scrubbing after shell env merging when changing child env builders

Bring the detached worktree fix into the local main line while preserving the newer main behavior that passes session context into interactive chat message blocks.
Constraint: Local main already contains six unpublished commits on top of origin/main
Constraint: Merge conflict only affected MessageList message rendering around sessionId propagation
Rejected: Overwrite main's MessageBlock call shape | would regress AskUserQuestion and permission interactions that need sessionId
Confidence: high
Scope-risk: moderate
Directive: Keep MessageBlock sessionId propagation when editing chat rendering; AskUserQuestion depends on it
Tested: cd desktop && bun run test -- MessageList.test.tsx
Not-tested: Full verify after merge; previous verify remains blocked by agent-utils global coverage baseline
Chat sessions need predictable navigation when users switch tabs or read history during streaming. This preserves each session's scroll position, defaults fresh sessions to the latest message, and adds a compact jump-to-latest affordance when auto-follow is paused.
The PR gate also exposed that provider-scoped scheduled tasks must force the sdk-cli entrypoint when launched through the sidecar, so the same change records that runtime contract and its regression assertion.
Constraint: Desktop chat should not force-scroll while the user is reading older messages
Constraint: Scheduled task provider env must not inherit stale parent model runtime values
Rejected: Persist scroll positions in localStorage | session scroll is transient UI state and should not survive app restarts
Confidence: high
Scope-risk: moderate
Directive: Do not remove the sdk-cli entrypoint marker from provider-scoped cron tasks without rerunning the sidecar launcher regression
Tested: cd desktop && bun run test -- MessageList.test.tsx

Scheduled task subprocesses should normalize their child environment instead of inheriting a stale parent entrypoint. Setting the default task entrypoint keeps launcher tests and non-OAuth task execution on the SDK CLI path while still allowing the official OAuth environment overlay to provide its desktop-specific entrypoint.
Constraint: Official OAuth tasks intentionally overlay provider-specific environment after the default child task environment is built
Rejected: Preserve parent CLAUDE_CODE_ENTRYPOINT | stale parent values can leak into scheduled task launches
Confidence: high
Scope-risk: narrow
Directive: Keep default task launcher environment deterministic before provider-specific overlays are applied
Tested: bun test src/server/__tests__/cron-scheduler-launcher.test.ts
Tested: bun run check:server
Not-tested: Full verify still blocked by existing agent-utils global coverage baseline
- Remove pr-checks lane from quality gate (not needed locally)
- Fix launcherRouting tests to pass explicit null envAppRoot to avoid CLAUDE_APP_ROOT pollution
- Fix cron-scheduler-launcher test: CLAUDE_CODE_ENTRYPOINT is correctly set to sdk-cli for scheduled tasks, update assertion and restore env var in cleanup

Scheduled tasks used the model selector in model-only mode, so a task could store a third-party model id without the provider runtime needed to execute it. The desktop task editor now stores the selected provider with the model, and the scheduler injects the same provider-scoped runtime env that desktop sessions use before launching the sidecar.
Constraint: Scheduled tasks run outside an active desktop websocket session, so provider runtime must be serialized on the task itself.
Rejected: Reuse session runtime localStorage for tasks | scheduled executions can run long after the UI session is gone.
Confidence: high
Scope-risk: moderate
Directive: Keep task execution provider env isolated from inherited process env; stale parent ANTHROPIC_* values must not override task provider choices.

Not-tested: Live third-party provider API call; covered by sidecar launch integration with provider proxy env.
Scheduled task Run Now was still constructing a source checkout Bun command, so packaged desktop builds could try to execute src/entrypoints/cli.tsx from a missing or wrong root. Resolve the same launcher used by the desktop runtime first, and keep the source checkout fallback only for development.
Constraint: Desktop Release tasks must run through the configured sidecar and app root instead of assuming source files exist on disk
Rejected: Retain import.meta.dir path math with broader fallback | still bypasses packaged desktop launcher and repeats the issue root cause
Confidence: high
Scope-risk: narrow
