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).
- install.ps1: remove published junctions lexically in Restore-MultiSkillSet
(Windows PowerShell 5.1 follows reparse points during Remove-Item -Recurse
and could delete canonical store contents); clean link staging dirs
lexically in Publish-CanonicalSkillLinks and Move-SkillPathRecoverably
- install.ps1: Test-SamePhysicalSkillRoot now dereferences junctions via
Get-PhysicalSkillPath (mirrors EvalSymlinks/realpathSync/cd -P), so reruns
recognize already-published junctions instead of backup churn
- install-event.sh: replace silent 'mv ... 2>/dev/null || true' rollback with
the loud backup-retained failure contract already enforced for devapp
- event/devapp sh+ps1: link→copy fallback and per-agent failures now degrade
per agent like install.sh (skip loudly, continue, report at the end)
instead of aborting mid-loop or swallowing errors
- tests: junction-lexical removal contract, event per-agent degrade
integration test, pwsh junction physical-root recognition + rerun
idempotency (no backup churn)
Point coverage, installers, IM skill-chain, and shared routing at
dingtalk-misc references after retiring the standalone event package.
