v0.2.0 — the dsh 0.2 comparison view

[0.2.0] — 2026-10-04

Ported to the review surface dsh 0.2 ships. Breaking: /review no longer
opens the pinned Changes page, because dsh 0.2 removed it along with per-chunk
Keep/Reject, the working-tree revert, and the rejection note that reached the
model. Nothing on the 0.2 side reverts a change behind the agent's back.

Changed

• /review now opens the newest recorded turn's changed files in the
  right sidebar, each with its side-by-side or unified comparison. That view is
  the changes-review tab type owned by @deepseek-ai/dsh-client-ui-deliverables.
• The command is offered only while all three of its preconditions hold: the
  comparison view is registered, the Session's right column is mounted, and the
  Session holds a turn whose changes the recorder announced. isMounted(), which
  dsh 0.2 removed from the right-sidebar service, is replaced by the
  mounted-Session snapshot.
• The dsh-change-review Skill was rewritten for the 0.2 record: the turn, not
  the tool call, is the unit the User reviews; only top-level turns are recorded,
  so a subagent's edits never reach the diff; comparisons live only while the
  Session lives; and nothing is reverted, so a comment on a change means the
  change is still in the file. It no longer teaches a rejection contract that
  0.2 cannot honour.
• The pack finds the turn's coordinates by reading the Session's own loaded event
  window (ctx.sessions.binding(sessionId).eventSource) instead of importing the
  changed-files constant. dsh.client.external is therefore empty, and the built
  browser bundle has no dependency on any other dsh package — the whole
  cross-package surface is restated in src/protocol.ts and pinned by tests.

Added

• src/protocol.ts — the one module that restates the surface this pack does not
  own (the tab kind, the workspace/changes event, and the
  dsh-resource://changes-review/session/<sessionId>/<seq>/<turn> address), with
  tests/protocol.spec.ts asserting each restated fact so an upstream rename
  fails loudly instead of turning /review into a silent no-op.
• Tests for the event-window scan, the three availability preconditions, the
  address encoding, and the refusal of an announcement whose payload names no
  turn.

Removed

• The dependency on @deepseek-ai/dsh-client-ui-sidebar-documentpreview and its
  CHANGES_KIND, which dsh 0.2 deleted.

Notes

• 0.1.x remains the release for a dsh 0.1.5 build, where the Changes page and
  keep/reject still exist. The README's compatibility table states which pack
  drives which dsh.
