The nested state summary, command-center drawer, execution-history drawer, and terminal runtime drawer could be logically active yet visually stacked behind the focused bottom-rail surface. | Fix: added shared overlay z-index classes in `apps/web/src/lib/overlayLayers.ts`, moved the bottom-rail host and all higher Orchestration overlays to those classes, and extended tests to assert the visual stacking contract. | Status: FIXED ### Low * No findings. ## Assumptions and Deliberate Non-Fixes * Active package is `apps/web`, based on the phase plan candidate session metadata and the changed file set. * Session documentation files were reviewed as workflow artifacts. They were left unchanged except for this generated review report. * No deliberate non-fixes remain. ## Behavior Changes * Nested Orchestration overlays now visually stack above the expanded bottom-rail focused surface. This changes observable stacking behavior, but it matches the session requirement that retained summaries and drawers close as higher layers before the focused Command Center surface closes. ## Verification * Tests: `npm test -- apps/web/tests/commandCenterShortcuts.test.ts apps/web/tests/keyboardShortcuts.test.ts apps/web/tests/KeyboardShortcutsModal.test.tsx apps/web/tests/BottomRailExpansionHost.test.tsx apps/web/tests/OrchestrationPanel.test.tsx` - PASS - 5 files, 133 tests. * Tests: `npm test -- apps/web/tests` - PASS - 132 files, 2073 tests. * Type checker: `npm run typecheck --workspace @factionos/web` - PASS - `tsc -b --noEmit`. * Formatter: `npm run format:check` - PASS - 771 files checked, no fixes applied. * Linter: `npm run lint` - PASS - 773 files checked, no fixes applied. * Whitespace: `git diff --check` - PASS. * ASCII/LF: `file` plus C-locale non-printable grep and CRLF grep over all uncommitted files - PASS. * Final diff re-read: no remaining issues. ## Summary 1. Reviewed 18 implementation/session files from the initial uncommitted working tree and generated this review report as the 19th uncommitted session artifact. 2. Findings: 0 critical, 0 high, 1 medium, 0 low; the medium stacking issue was fixed. 3. No unresolved blockers or deliberate non-fixes remain. 4. Focused tests, full web tests, web typecheck, formatter, linter, whitespace, and ASCII/LF checks pass. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://faction-os.gitbook.io/faction-os-docs/.spec_system/archive/sessions/phase21-session04-shortcut-and-overlay-layering/code-review.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
