P3-09 — snapshot diff dispatcher.
- POST /api/hosts/{id}/snapshots/diff (and the unprefixed HTMX-form
variant) takes {snapshot_a, snapshot_b}, validates both belong to
the host (long id / short id / prefix match), checks the agent is
online, mints a JobDiff, ships command.run with DiffPayload, writes
a host.snapshot_diff audit row, returns HX-Redirect to the live
job page (or JSON {job_id, job_url} for REST callers).
- Two-snapshot guard: POSTing diff(a,a) returns 422.
- UI: small panel on the host_detail right rail (visible when the
host has 2+ snapshots) with two short-id inputs and a Diff button.
Output renders on the standard live job page where the operator
reads the per-line diff text directly.
P3-X3 — recent-restores line.
- hostChromeData grows RestoreStatus / RestoreAt / RestoreJobID
populated via store.LatestJobByKind(host_id, 'restore') (already
exists, used by the init line).
- host_chrome.html renders a small line below the existing init-status
one with status-coloured copy + a link to the job log. Hidden when
no restore has ever run on this host.
Tests:
- diff_test covers happy path (correct DiffPayload + HX-Redirect),
same-id rejection (422), unknown-id rejection (422). Adds a
seedTwoSnapshots helper since ReplaceHostSnapshots is atomic-swap
(calling seedSnapshot twice would only leave the second).
Restage block (CLAUDE.md) deferred to the end of the restore phase.
restic-manager
Self-hosted, browser-based, single-pane-of-glass for managing restic backups across a fleet of Linux and Windows endpoints.
Status: pre-alpha. Phase 0 (project bootstrap) complete; Phase 1 (MVP) in progress. See
spec.mdfor the design andtasks.mdfor the roadmap.
What it does (target)
- Central visibility into backup state for every endpoint
- Trigger any restic operation remotely (
backup,forget,prune,check,unlock,snapshots,stats,diff,restore) - Manage per-host backup schedules from the UI
- Live job progress streamed back to the UI
- Restore wizard (browse snapshots, pick paths, restore to original or alternate host)
- Repo health surfacing (size, dedup ratio, last check, lock state)
- Alerting on failure or staleness
- Cross-platform agent (Linux + Windows)
- Ransomware-resistant repo access via append-only credentials
Architecture (one-line summary)
A small Go control-plane on the Proxmox host, lightweight Go agents on each
endpoint that hold an outbound WebSocket to the control-plane, and a
restic/rest-server on Unraid that holds the actual backup data. The
control-plane never touches backup bytes.

Local development
Requires Go 1.25+ (built and tested on 1.26). The floor is set by
modernc.org/sqlite v1.50.
make build # builds cmd/server and cmd/agent into ./bin
make test # runs go test ./...
make lint # runs golangci-lint
make run-server # runs the server (dev defaults)
