Refresh AI Code Review Landscape research — 2026-11-29

## Type

## Area

## Priority

P3 — Low

## Problem

The **AI Code Review Landscape** page created by #32 is an explicit point-in-time snapshot. AI code-review products change quickly: features ship or are withdrawn, vendors rebrand, and new competitors appear. Without a scheduled re-check, the page silently goes stale and its comparison claims stop being trustworthy.

## Goal

The AI Code Review Landscape page is refreshed against current official sources, with an updated `Research snapshot` date and corrected comparison claims, without rebuilding the Wiki or changing Skill behavior.

Intended review date: `2026-11-29`.

## Scope

- Re-check every product in the existing Wiki landscape page.
- Verify whether each product / feature is still active and still available as a review capability.
- Detect significant new competitors and add them only if verified active and meaningfully comparable.
- Refresh capabilities from current official / primary sources.
- Update the `Research snapshot: YYYY-MM-DD` date.
- Update comparison claims and matrix values that became stale.
- Update this repository's capability descriptions if the repository itself changed since the previous snapshot.
- Preserve neutral evidence discipline: separate verified capabilities, vendor claims, and independent evidence; keep `Unknown / not verified` where evidence is insufficient.

## Non-Goals

- Recreating the Wiki or its information architecture (owned by #32).
- Changing normative Skill behavior, review semantics, or packaging as part of the refresh.
- Building any automation, workflow, or scheduled job for the refresh date — this issue is only the backlog item.

## Acceptance Criteria

- [ ] Every previously listed product has been re-verified against a current official source.
- [ ] Newly significant competitors are evaluated; additions pass the active + comparable check, exclusions are recorded with a reason.
- [ ] The page carries an updated `Research snapshot` date.
- [ ] Stale comparison claims / matrix values are corrected; unverifiable items remain `Unknown / not verified`.
- [ ] This repository's capability descriptions match the current canonical Skill and policy files.
- [ ] No Skill behavior, review semantics, or packaging semantics changed.

## Dependencies

Depends on: #32
Blocks: none
Parent: none

## Validation

- Per-product official sources are listed with access dates; links resolve.
- Diff of the landscape page shows the snapshot date change and only evidence-backed claim updates.
- Repository validation still passes; any repository-side diff is limited to Wiki / navigation content.
- Intended review date recorded in this issue: `2026-11-29`.
