agent-go: engineReport gains singBoxVersion. The probe runs
`sing-box version` once, parses the version token from its first line
('unknown' from unstamped builds reports empty), and caches it keyed by
the binary's mtime+size — re-probed only when an engine install/update
replaces the file. Steady-state heartbeats pay one stat, no subprocess.
Agent version stays 0.6.8.
panel-go: EngineState.singBoxVersion persisted from heartbeats (old
agents without the field keep showing '-'), servers table core-version
column now renders it. Golden gains heartbeatWithEngine +
serversAfterEngineHeartbeat sections locking the full chain, plus a
listen-address (<hostip>) normalization for the sandbox bind address.
singboxversion_test.go covers parsing, cache hits, and re-probe on
binary replacement.
GET /api/customers gains a summary object (total/online/depleted/
depletingSoon/disabled/enabled) computed server-side; the customers page
renders it as a six-cell stats strip above the toolbar.
Predicates aligned verbatim with 3x-ui client_paging.go:
- depleted = (limit>0 && used>=limit) || (expiry set && expiry<=now),
counted regardless of status;
- depletingSoon = active && !depleted && (expiry within expireDiff days
|| remaining traffic < trafficDiff GB), thresholds from new settings
expireDiff/trafficDiff with 3x-ui's factory default 0 (nobody counts
until configured);
- enabled = status active; disabled = manual suspensions only.
Online reuses the existing 3-minute presence projection.
Golden diff confined to the additive summary keys; summary_test.go
covers every bucket with thresholds off (soon=0) and on (soon=2).
NormalizeNode re-selected ports whenever the request merely CONTAINED
port/serverId keys; the browser form always submits them (port=null in
random mode), so every save re-rolled both entry and exit ports. Now an
assigned port only moves on an explicit addressing change: mode switch to
random, a different fixed port value, or a server move where the port is
taken (fixed mode surfaces the 409). random->fixed pins the current port.
Regression: portlock_test.go (UI-shape payload saved twice, rename-only,
mode switches, fixed change/conflict, server move free/taken).
Golden re-captured: diff confined to nodePatchUiStyle/nodePatchJobs/
nodesAfterPatch/backup port leaves returning to the seed ports.
Single-source Go from this round on: golden.mjs replays a fixed API script
against a Go panel seeded from the difftest seed DB and diffs every response
(learning-normalized) against golden.json. 25 sections: lists, credentials,
all subscription formats, deploy job payloads, usage/presence, UI-style node
PATCH, /api/system shape, backup, error cases.
