# Processed + UI Finalized Merge Report

Generated UTC: 2026-07-23T17:22:53Z

## Decision
The final package uses the user-attached `processed(1)` archive as the base because it contains the fuller Phase 4 backend/audit implementation and its associated migration/test coverage. The UI-specific responsive fixes from `ui-finalized` were then applied on top.

## Applied UI corrections
- Changed mobile quick-navigation hiding from `.quicknav a span{display:none}` to `.quicknav a>span:not(.medallion){display:none}` so icon medallions remain visible on narrow screens.
- Added `aria-label` values to every quick-navigation tab so icon-only mobile navigation remains accessible.
- Kept the top toolbar controls visible below `980px` by overriding the previous `.toolbar-cluster{display:none}` behavior.
- Allowed the top bar to wrap and scroll horizontally where needed on mobile/tablet widths.
- Added `test_mobile_navigation_keeps_icons_and_touch_controls_visible` to lock the regression.

## Preserved backend/audit work from processed base
- Phase 4 execution command contracts and error taxonomy.
- Durable execution audit/session files.
- SQLite and PostgreSQL execution-audit migrations.
- Phase 4 state-machine, validation-order, locking/durability, client-routing, and adjacent-gap audit tests.
- Execution client-path and adjacent-path audit scripts.

## Verification
- Full local pytest suite: `364 passed, 1 warning`.
- UI/frontend contract subset: `25 passed`.
- Execution client-path audit: `0 findings`.
- Phase 4 adjacent-path audit: `0 findings`.
- Repository metadata verifier: `PASS`.
- Secret scan: `0 findings`.
- Migration checks: `PASS` for SQLite and PostgreSQL migration inventories.
- Runbook consistency: `CONSISTENT`.

## Remaining status
This is still a Paper-only working package. Testnet, Live, autonomous execution, credential rotation, upstream approval, independent audit, and final sign-off remain external/operator-controlled gates.
