Summary

Extends the verified compatibility range from 0.2.2-alpha.2 to the latest dsh-v0.2.2-rc.1 by adding the two releases in between:

• 0.2.2-alpha.3
• 0.2.2-rc.1

The development pin and committed lockfile stay on 0.2.0-rc.2.

Interface review (upstream tags)

• dsh-v0.2.2-alpha.2 → dsh-v0.2.2-alpha.3: 2315 files changed. This is a real feature release: the host runtime moves to Cordis 4.0.6-alpha.2 / schemastery 3.18.6-alpha.2, the host vendor sources pick up the Cordis 4.1.0 changes, and the client ships the new context menu package and plugin-manager config slots.
• dsh-v0.2.2-alpha.3 → dsh-v0.2.2-rc.1: 387 files, a release-version-only republish (111 seam manifests, one version line each). It moves the host runtime to Cordis 4.1.0 / schemastery 3.19.0.

The packages this plugin consumes were checked against the plugin's actual seams:

Seam	Result
Host Git / subprocess / credentials / working-directory	Version bumps only; resolveExecutable, spawn, argv handling and the credentials key/ref contract are unchanged.
Commit message / LLM	dsh-llm makes GenerateOptions generic with an empty default LlmRequestPurposeMap; the plugin never passed purpose, and stream text-delta / currentSelection() keep their shape.
Session / RPC	Projection updates now bundle multiple changed keys per committed event (changes[]); SessionSummary.cwd and projectionValues are unchanged, so effectiveWorkspacePath keeps working.
Sidebar / slots	Sidebar-right adds contextMenus, openResource.destination and SidebarRightTabInfo.panel.isFloating. The plugin calls openTab / openResource without placement overrides and reads only tab from useTabInfo().
Settings	Adds settings.section.icon; configForms.get, the volatile reference semantics and plugins.bundle.config registration are unchanged.
Primitives / icons / Diff	Additions only (Menu contextual options, MENU_TRANSITION_MS, useMarkdownDelegate, save icons). DiffBlock, diffTotals, MarkdownText, Toast, Modal, Tag, Switch, Pill and every Medium glyph keep their contracts.

Adaptation

• Composer tooltip. 0.2.2-alpha.3 makes the docked composer seat a containing block for fixed descendants (will-change: transform), and the host now requires fixed overlays in the composer to portal to document.body. The branch/changes tooltip in conversation.input.left now goes through src/compat/dsh-tooltip.tsx, which probes the installed Tooltip signature (portal exists from 0.1.7-alpha.1) and forwards portal: true where supported. The 0.1.5 / 0.1.6 copies ignore the extra prop.
• Declarations. Both releases are added to SUPPORTED_DSH_RELEASES and CREDENTIALS_SEAM_DSH_RELEASES, every DSH peer OR, and engines.dsh.
• Runtime ranges. Added || ~4.0.6-alpha.2 to the Cordis peer and || ~3.18.6-alpha.2 to the schemastery dependency so the exact declared-floor gate accepts alpha.3. rc.1's stable 4.1.0 / 3.19.0 fall inside the existing base ranges.
• CI. Every published 0.2.2 lane now uses Node 24.9.0; older hosts stay on 22.19.0.
• Not added to peer OR. @deepseek-ai/dsh-client-ui-context-menu only exists from alpha.3 and is a runtime import of sidebar-right; adding it to a range covering older hosts would break their app-boot preflight. The host composition provides it, and the plugin source does not import it.

Validation

• 0.2.2-rc.1 first passed as an unlisted candidate (DSH_COMPAT_MODE=warn) across all gates.
• 0.2.2-alpha.3's first candidate failed only the compat gate because the old ranges rejected the host copies 4.0.6-alpha.2 / 3.18.6-alpha.2; after adding the OR clauses its formal lane passed every gate.
• Formal isolated matrix over all 23 supported releases: bootstrap, applicable upgrade/install, peers, compat, tests, docs, build, artifact and pack all pass. The two new lanes and the development pin each pass 1043 unit tests and 7 artifact checks.
• Browser fixture suite: 28/28 on the development pin and 28/28 on 0.2.2-rc.1. (An earlier rc.1 run flaked on one accounts dialog test; that test passes in isolation and on the final run.)
• The tooltip compatibility test now hovers the anchor and asserts the bubble's host: document.body where the installed Tooltip supports portal, the render container without data-portal where it does not. This replaces the probe-only assertion raised in review.
• Evidence: docs/reference/dsh-adaptation-20261111.json.

Not covered

• No local Linux/Windows run; PR CI passed on Ubuntu, macOS and Windows.
• No full DSH Web/Desktop profile installation or native enhancement unload run.
• No real remote account acceptance.

CI passed after the review follow-up.

Addressed the review flag: the composer tooltip test now hovers the anchor and asserts the bubble host — where the installed Tooltip supports , the render container (without ) where it does not. It fires both mouse- and pointer-event paths so the pointer switch is covered. Refreshed the 23-lane matrix evidence (1043 tests per lane) and pushed ; CI is green.
