Pinning the lane to 0.1.6-alpha.2 makes plugin-mount fail deterministically:
the shell boots into the new-session empty state, no session scope reaches the
sidebar, and [data-dsh-better-sidebar] [title] never attaches
(mount.e2e.ts:216 plus perf.e2e.ts:182). Falsified against this branch with a
probe: origin/main + that one-line pin, run 35484961070, same red, zero plugin
changes involved.
So the dev tree keeps alpha.2 (the line the maintainer's desktop runs) while
the lane stays on the released pin; the evidence and the follow-up (teach the
lane to activate the seeded session on the alpha line) are recorded in
AGENTS.md §2/§3 and docs/plans/2026-09-17-dsh-0.1.6-alpha.2-adaptation.md.
