§2.1 — IP race with capacity>1 (Invoke-CIJob.ps1)
Phases 2-3b (clone+start+IP) now run inside a file-based exclusive mutex
(F:\CI\State\vm-start.lock via FileShare.None). Only one job at a time is
in the VM-start phase, preventing concurrent vmrun starts from racing for
the same DHCP lease. After IP is confirmed unique it is written to an IP
lease file (F:\CI\State\ip-leases\<IP>.lease). Lock is released immediately
so build phases run fully in parallel. Lease released in finally block.
Collision detection: if a lease file already exists for the detected IP,
the job fails fast with a clear error rather than silently sharing a WinRM target.
§2.5 — Versioned snapshot (Invoke-CIJob.ps1 + runner/config.yaml)
$SnapshotName now defaults to GITEA_CI_SNAPSHOT_NAME env var, falling back
to 'BaseClean'. config.yaml documents the commented-out variable for snapshot
refresh workflow (BaseClean_<yyyyMMdd> naming convention).
§2.3 — Artifact/log retention (scripts/Invoke-RetentionPolicy.ps1)
Purges per-job subdirs under F:\CI\Artifacts and F:\CI\Logs older than
RetentionDays (default 30). Switches to AggressiveRetentionDays (default 7)
when F: free space drops below MinFreeGB (default 50 GB). Also removes stale
IP lease files older than 12 hours (defensive cleanup for crashed jobs).
SupportsShouldProcess (-WhatIf) for dry-run.
§2.2 — Scheduled task registration (scripts/Register-CIScheduledTasks.ps1)
Registers two tasks under \CI\ task folder as SYSTEM/HighestPrivilege:
CI-CleanupOrphans — every 6h + AtStartup, -MaxAgeHours 4
CI-RetentionPolicy — daily 03:00 (+30min random) + AtStartup (+15min random)
Idempotent (-Force), SupportsShouldProcess (-WhatIf), validates script paths.
