Accessibility Conformance Report

Based on VPAT® Version 2.5 · Report date: 2026-08-26 · Product: brain-server web console + desktop client Evaluation method: automated axe-core scans on the served console build + keyboard-only manual walkthroughs of every panel. Posture per house rule: documented conformance claim backed by evidence, not a certification.

Standards applied

Conformance level claimed

Partially supports WCAG 2.2 AA — every Success Criterion is either met (evidence below) or listed under Known Ceilings with its remediation owner. No criterion is “does not support” without an entry there.

WCAG 2.2 criteria — evidence summary

The machine-checkable list lives in wcag22-aa-checklist.md; the release gate (wcag_22_aa_gate_blocks_release) fails when any criterion loses its pass or its documented ceiling. Highlights:

• Perceivable: text alternatives on icon-only buttons (aria-label from the locale bundle — the same t() surface, so translations carry accessibility labels too); contrast verified against both shipped themes (dark/light) at AA ratios; no information conveyed by color alone in verdict/status chips (text label always present).
• Operable: full keyboard operation (the review flow is keyboard-first: A/S/R/E/J/K shortcuts with visible focus); 2.4.7 focus-visible styling ships in both themes; 2.4.11 focus never obscured — every focused node carries a scroll margin clearing the sticky header and bottom bar (focus_never_obscured_by_docks); 2.5.8 target size ≥ 24×24 CSS px enforced at the component-class level (target_size_floor_24px_enforced_by_classes); 2.5.7 dragging — no drag interaction ships; a marked click alternative is required for any future one (drag_alternatives_exist_for_every_drag); reflow to 320 px / 400% zoom.
• Understandable: page language follows the active locale (ar sets dir="rtl", mirrored layout pinned by rtl_mirroring_smoke_all_panels; pseudolocale elongation budgeted by pseudolocale_elongation_renders_without_truncation); ONE consistent help entry on every panel (3.2.6, help_entry_consistent_across_panels); no redundant entry in decision flows (3.3.7, no_redundant_entry_in_approval_flow); auth is token paste/keyring with no cognitive test (3.3.8); error messages are text, tied to their input.
• Robust: semantic HTML controls (native button/input), labels bound via for/aria-label; status changes announced through live regions on the review queue.

EN 301 549 clause 11 (desktop client, non-web software)

Known ceilings (honest)

• Locale negotiation is exact-match only. The switcher sanitizes to the supported set without region/script subtag matching (fr-CA falls to default en, not fr); the requested→available→default scheme is documented in client/src/i18n.rs and full BCP-47 matching remains future work with the fluent-langneg upgrade.
• axe browser gate covers the web console only. The axe scan runs against the served console build; the desktop shell is covered by the manual keyboard walkthrough + clause-11 self-assessment above, not by axe.
• Focus restoration after modal close is not yet guaranteed everywhere. Drawers restore focus to their invoker; the command palette and the confirm dialog do not yet — tracked as an open a11y defect, remediation planned before the next ACR revision.
• RTL mirroring is attribute-level (dir="rtl"); deep bidirectional text in mixed-content transcripts relies on browser bidi algorithms — no dedicated Unicode bidi audit has been run.
• The report reflects the build dated above; each release re-runs the gate, but manual walkthrough evidence refreshes only when UI panels change.
