release: establish the SPACE 0.8.2 guest-update baseline - #1747
Reserve SPACE 0.8.2 as the shared workspace baseline for manager-owned Linux/Windows guest maintenance and node-local automatic scheduling. Advance the guest-update marker to 0.8.2 and synchronize both workspace and fuzz lockfiles. The fuzz workflow now runs on workspace manifest changes too.
Maintenance requires a committed guest version of at least 0.8.2 and a recovery contract matching the trusted image profile. Before recreation, verify the replacement meets both requirements. Older guests continue serving work; the separate manual fallback supports only legacy Linux regular-file layouts. Older Windows and two-slot guests require recreation or qualified repair.
This bump reserves the baseline without minting an immutable release tag or implementing serialized publication. Commit-tagged development builds may seed new templates. Within one recovery contract and architecture, installed catalogs must not offer different bytes under an already-used workspace version. Different platform/architecture entries may share that version. Release owners must coordinate subsequent allocations and advance the version and marker before offering guest-relevant changes to existing guests.
Validation
Verified that lockfile changes track workspace versions, including the node-status-store crate added on main after this release bump was prepared. After rebasing, cargo metadata --locked --all-features passes for the combined workspace. cargo fetch --locked passed in fuzz/. Feature validation is reported in the parent PRs; CI runs on this release head.
Severity and risk
Severity does not apply: this is release metadata and lockfile consistency.
Deploy the stack together. Reverting only the version bump leaves the fixed maintenance floor unchanged and makes newly built older guests ineligible. Host rollback requires a compatible migration catalog and preservation of receipt/policy history; dropping history is not a state-preserving rollback. See the rollback guidance.
Future marker bumps can restart eligible idle guests after a newer authorized target is installed. Compatibility, exact target ceilings, lifecycle priority and the node kill switch still apply.

Walkthrough
The workspace version and guest-update marker change from 0.8.1 to 0.8.2. The versioning documentation describes guest eligibility, recovery-contract requirements, version allocation, and rollback constraints. The DHCP fuzz workflow adds the root Cargo.toml to its pull-request path filters.

Before / after behavior
observed — Modified behavior in ci/guest-update-required-since: The version value changes from 0.8.1 to 0.8.2.
observed — Modified behavior in docs/versioning.md: Added guest-update eligibility and replacement-template requirements: committed guest version must be at least 0.8.2 and the recovery contract must match the trusted image profile. Older guests are excluded from automatic selection. The documented manual procedure is limited to legacy Linux guests with regular spaced binaries; Windows and two-slot guests require recreation or separately qualified repair.
observed — Modified behavior in docs/versioning.md: Added release-management constraints: 0.8.2 reserves a maintenance baseline but does not create a release tag or serialized publication. Guest-relevant releases require coordinated workspace-version and guest-marker advances. Within the same recovery contract and architecture, equal workspace versions must not offer different guest bytes; platform or architecture entries may differ. Commit-tagged builds may seed templates but cannot authorize equal-version replacement. The text also documents the consequences of reverting the version bump and requires compatible migration and state-preserving recovery planning for feature rollback, including the risk of newer migrations and loss of recovery evidence.
observed — Modified behavior in Cargo.toml: The workspace package version changes from 0.8.1 to 0.8.2.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Qualify the replacement template before recreation.
A newly built template can still contain an older guest or use the legacy layout. Recreating from it can leave the replacement ineligible for maintenance. The runbook requires a committed version of at least 0.8.2 and describes the required updater-capable layout in docs/spaced-upgrades.md, Lines 76-90 and 173-176. Add those requirements here or link to that guidance. (raw.githubusercontent.com)

## Summary
Advance the shared SPACE workspace version and guest-update marker from 0.8.1 to 0.8.2 as the baseline for Linux and Windows guest maintenance and node-local automatic scheduling. There is no separate spaced version or compatibility-family change.
Manager-owned maintenance starts from guests committed on 0.8.2 or newer. This release does not automatically migrate older guests; they need recreation from a current template or the separate manual procedure. Future guest-relevant releases advance the marker to update eligible guests from this baseline. Keeping the release bump separate makes rollout independently reviewable. Reverting it alone leaves the feature floor at 0.8.2 and disables maintenance for newly built older guests; deploy the stack together.
## Validation
Validated with the complete guest-update stack using targeted eligibility, scheduling, authority, catalog and installer checks. Both workspace and fuzz lockfiles track the new workspace versions; dependencies are unchanged by this release commit. The fuzz workflow now also runs on workspace manifest changes. cargo fetch --locked passed in fuzz/. Full CI runs on this head.
## Severity and risk
Severity: Does not apply: this is release metadata and lockfile consistency, not a vulnerability fix.
A future marker bump can restart eligible idle guests on each enabled node after a newer bundle is installed. Catalog ceilings, lifecycle priority and the node kill switch still apply. This establishes an ordered baseline; same-version development rebuilds remain ineligible for automatic replacement. Merge after the scheduler and catalog PRs.
AI assistance: Codex updated the version, lockfile, marker, documentation and this description.
This bump reserves the first supported maintenance version; it does not mint an immutable release or implement serialized allocation. Release owners must coordinate later versions against main and advance version/marker before publishing guest-relevant changes.
Review refinement: reject out-of-range versions before publishing any bundle; document that the legacy manual fallback supports Linux regular-file layouts only.
Commit-tagged builds may seed new templates; installed catalogs cannot offer different bytes under an already-used target version. Rollback requires compatible migration catalogs and state-preserving recovery.
Regenerate release metadata against current main so newly added workspace crates, including node-status-store, are recorded at 0.8.2 in Cargo.lock. A textual lockfile merge can retain the previous workspace version and break every locked Cargo check. Full workspace metadata with --locked --all-features and fuzz cargo fetch --locked pass after rebasing.
