Restrict backup pruning to directories whose names match the DWS stamp
format (YYYYmmdd-HHMMSS with optional -N suffix) across all 8 installer
surfaces (Go, npm, 4 shell, 2 PowerShell). Unknown directories in
~/.dws/skill-backups are now preserved. Also fixes Windows coverage test
portability and covers the remaining macOS changed-code gap (retire
warning loop in runUpgrade).
A universal Agent whose obsolete private copy cannot be retired installs
nothing there, yet every entry point counted that retirement failure as an
install failure — aborting `npm install`, `dws skill setup`, and the shell
installers even when the canonical store and all links published correctly,
and skipping the skills-state write. Route retirement failures to a separate
warning path across all surfaces (Go upgrade + skill setup, npm, PowerShell,
install.sh, install-skills.sh, install-event.sh, install-devapp.sh).
Also:
- Add a checked-rename fallback for filesystems that reject the atomic
no-replace flag (NFS, FUSE, overlayfs); the no-clobber contract is kept and
the previously unsupported platforms build and work.
- PowerShell multi-mode links only bundle skills, never the shared canonical
store, so third-party/user skills are no longer fanned into every Agent root.
- Prune ~/.dws/skill-backups to the newest 5 on every surface; encode
HOME-relative backup names on PowerShell to preserve origin.
- Add simulated-win32 junction coverage and rewrite the tautological
no-replace test; remove dead code whose tests gave false coverage.
- Soften the overstated Windows ownership-proof comment (NTFS tunneling).
Flip the agent-skill default from mono (single dws/ dir) to multi
(per-product dingtalk-* + dws-shared) across all distribution faces,
and fix the upgrade path so it no longer re-installs mono alongside
multi (mono+multi co-existence bug).
- upgrade: LocateSkillsRoot prefers the zip multi/ tree; multi refresh
removes mono leftovers and stale skills, refreshes the multi cache
- install.sh/ps1/install-skills.sh/npm install.js: multi real-install
(was print-only), default flipped, mono stays opt-in via DWS_SKILL_MODE
- skill setup: non-interactive default multi; full installs now clean
stale dingtalk-*/dws-shared with confirm-preview disclosure, filtered
(-s/-x) installs stay additive
- mutual exclusion is symmetric and includes dws-shared (previously
leaked through the dingtalk- prefix) on all faces
- install.js: guard empty/corrupt multi trees (fall back to mono),
validate SKILL.md on the mono branch, guard cache refreshes
- docs: roadmap (8/30 back-schedule), migration plan, distribution
mechanism, rollout capability, capability completion, architecture
optimization, wukong comparison (archived; line retired)
