Prerequisite for removing the nginx global-auth layer in front of the
gateway: llmsproxy must defend its own login endpoint.
Design:
- per-IP failure counter: 5 consecutive failures trigger an exponential
lockout (30s base, doubling per extra burst, capped at 30min); 15min of
quiet forgives the counter
- global budget: max 100 failures/minute across all IPs so a distributed
spray cannot outrun per-IP windows
- locked-out and over-budget attempts get the SAME 'invalid gateway api
key' 401 as normal failures — no oracle to probe lockout state, no info
leak on key validity timing
- successful login clears the IP's counter entirely
- clientIP(): prefers X-Real-IP (trusted nginx proxy), falls back to
RemoteAddr host
Tests: lockout engages at threshold with identical replies, valid keys
rejected while locked, other IPs unaffected, success resets counters,
X-Real-IP extraction.
- Req: add FirstByteMs field (ms to first byte, tracked for streaming)
- Stat: add FirstByteSum for aggregation
- SourceAverages(): new method computing per-source avg TTFB and tokens/s
from the in-memory ring (300s window)
- SourceStatus: add AvgFirstByteMs and AvgTokPerS fields
- pumpStream: record FirstByteMs after first SSE chunk sent to client
- singleChat/singleChatAuto: set FirstByteMs = LatMs (non-streaming)
- handleStatusAPI: populate the new SourceStatus fields from SourceAverages()
- WebUI source table: two new columns showing TTFB (s) and Tokens/s
statusRecorder (the access-log wrapper) did not implement http.Flusher, so
w.(http.Flusher) inside streamChat/streamChatAuto returned nil and every SSE
chunk stayed buffered until the response ended. Add Flush() that delegates to
the underlying writer when it supports flushing.
Regression test: TestStatusRecorderFlusher pins the interface assertion and
the forwarding path.
- api/status sources now carry recent_ok/recent_err (last 300s real gateway
requests via Stats.SourceRecent) so a source actually serving traffic is
never shown as down just because probe /models got rate-limited
- WebUI source status column repaints every 5s (no more frozen-at-first-
render) with a manual refresh button; shows success rate + probe + cooldown
- tray menu status rows were enabled:false (GTK fixed light-grey, invisible
on light themes) — now enabled with no-op click and nativeTheme listener
rebuilds the menu on dark/light switches
- ignore local ops scripts (scripts/, machine-specific)
ensureProbe() called Registry.ProbeAll() synchronously on every status request when >30s had passed since the last probe, blocking the response on the slowest upstream (zen ~1s, frank ~1.9s, total ~1.5s) — this stalled WebUI page loads and tab switches. Now the probe runs in a background goroutine (15s budget); status returns in ~7ms and the 3s stats poll picks up updated reachability next tick. Deployed (bak .bak.20260811s), server active.
- scheduler: BuildChain sorts tiers ascending so tier 1 (highest priority) is tried first; previously descending inverted the chain (P10-1..P10-5)
- stats/api: handleStatsAPI limit→20000; CSV reads full audit via new Stats.AuditRecords (includes *.old rotation); key_names mapped by keyID() masked key; non-admin filter and keys-csv use masked keys
- server: ring buffer NewStats(10000)
- ui: dash-row card scroll area moved to table container (fix overflow below card); key view toggle (re-click same key returns to global) + kpi-exit affordance; rec-exit span
- chat: chain-failure record now surfaces first failed tier; AUTO comment sync
