diagnose(proof): attribute Power Mode Axe surfaces

[bizzybee90]

Purpose

The governed staging proof for exact main 08bb88946494806a534db904ab9725cd9207788e reached the Drafts desktop accessibility audit and failed closed with three serious color-contrast incomplete nodes, all safely reported as unattributed. This change adds fixed source-owned Power Mode surface labels so the next governed proof can identify the affected UI region without exposing selectors, DOM text, customer data, or raw Axe node details.

Included scope

• Add six fixed Power Mode Axe surface labels: route, header, empty list, empty pane, empty status, and empty copy.
• Attach each label exactly once to the existing desktop layout.
• Extend the existing literal label and source-ownership tests.

Explicit exclusions

• No colour, typography, layout, route, request, acceptance, timeout, or accessibility-rule change.
• No product-proof network policy, cardinality, evidence eligibility, or staging mutation change.
• No database, schema, RLS, provider, credential, production, or deployment change.

Architecture placement

Current owner / directory: the existing Axe sanitizer in scripts/product-proof-cloud-playwright.mjs and the existing Power Mode desktop layout in src/components/layout/PowerModeLayout.tsx.

Dependencies and duplicate-system check: extends the existing frozen surface allowlist and nearest-source-owned-surface classifier; no new diagnostic or UI subsystem.

Security and tenancy impact

• Authentication / authorization: none.
• Tenant isolation: unchanged; labels are fixed source literals and contain no tenant or customer identity.
• Service-role impact: none.
• Provider / webhook impact: none.
• Secrets impact: none; selectors, text, raw DOM nodes, URLs, headers, bodies, IDs, and credentials remain excluded.

Data impact

• Schema / migration / RLS / grant impact: none.
• Backfill, retention, or rollback: none; one-commit code rollback only.

Verification

• Behavioural tests: full cloud Playwright adapter suite 190/190; focused Power Mode/landmark Vitest 10/10; focused Axe tests 3/3.
• Static checks: scoped ESLint, TypeScript typecheck, Node syntax, and git diff --check pass.
• Security review: diagnostic-only, fixed literals, exact source ownership, and no raw-data path; zero findings.
• Governed proof: run 31444751918 cleanup/postflight/recovery passed and published zero evidence artifacts; a fresh exact-head preview and proof remain mandatory after merge.

Release safety

• Deployment scope: private no-index preview only after protected exact-head merge.
• Monitoring / stop conditions: stop on any gate failure, unsafe/malformed attribution, changed failure code, cleanup/postflight/recovery failure, or evidence publication before a complete proof.
• Rollback or containment: revert this one commit; production remains unchanged.

Documentation and generated files

• Docs / diagrams / ADR updates: none; no architecture, gate, schema, or release-policy change.
• Generated-file or lockfile justification: none.

Completion check

• Starts from current origin/main.
• No valuable work remains only in a dirty worktree, stash, or local-only branch.
• Source branch will be retired under the branch policy after merge.
• Any PR-size or branch-retention exception is documented below, or neither applies.

Summary by CodeRabbit

• Accessibility
  • Improved accessibility labeling across Power Mode screens, including headers, routes, empty states, conversation lists, panes, and status indicators.
  • Enhanced automated accessibility verification for these interface areas.

📝 Walkthrough

Walkthrough

Power Mode now exposes six product-proof Axe surface markers across its route, header, empty states, and status indicator. The Axe contract and ownership test include these markers and scan PowerModeLayout.tsx.

Changes

Power Mode accessibility coverage

Layer / File(s)	Summary
Add Power Mode surface markers scripts/product-proof-cloud-playwright.mjs, src/components/layout/PowerModeLayout.tsx	The Axe surface-label contract adds six Power Mode labels. The layout adds matching identifiers to the route, header, empty list, empty pane, status, and empty-state copy.
Validate surface ownership scripts/product-proof-cloud-playwright.test.mjs	The ownership test includes the six labels, uses product-wide coverage wording, and scans PowerModeLayout.tsx.
