delSource and delTemplate called api() without a method, so fetch
defaulted to GET; the DELETE handlers never ran and the UI silently
left the item in place.
A template stores every source field except name and api_key, so
operators spin up N key-bearing sources from one shared skeleton
instead of duplicating the whole source block N times.
- config: SourceTemplate type + RuntimeConfig.SourceTemplates stored
in runtime.json alongside runtime sources
- store: UpsertTemplate / ListTemplates / RemoveTemplate
- core: Templates / SaveTemplate / RemoveTemplate
- gateway: GET/POST/DELETE /api/source_templates
- webui: source list gains a Templates button opening a manager with
per-template edit/delete; the add-source dialog gains 'from
template' (event-delegated picker) and 'as template' (card modal)
buttons in its header; z-index fixed so the template editor layers
above the manager
Image models previously could not be scheduled through a priority
chain: the chat AUTO chain explicitly skips image-kind slots, and
AUTO image requests fell back to unordered registry discovery.
- config: add auto_image rules (auto_image yaml / image_rules json);
legacy auto rules keep their meaning as the chat chain
- core: buildAutoImageChain mirrors buildAutoChain with inverted kind
filter (image-only); SaveAutoImageRules + AutoImageRules/AutoImageChain
- scheduler: ChainImage walks the chain tier-by-tier with round-robin
and preference ordering, skipping cooling slots
- gateway: handleImage AUTO now runs down AutoImageChain when one is
configured (falls back to legacy discovery otherwise) and records
the actual served model; handleAutoAPI GET returns image_rules and
PUT accepts image_rules independently of rules
- webui: priority page gains a chat/image toggle editing two
independent lane sets; add-slot picker filters by active kind;
persistAuto writes only the active chain's field
The priority page and key-scope pickers skipped kind=image models,
so image sources (e.g. Kwai-Kolors/Kolors) could not be placed in
the AUTO chain or granted per-key. The backend already supports it:
handleImage resolves AUTO through the chain then filters with
imageOnly, while chat requests are protected by chatOnly, so image
slots never receive chat traffic.
Image models now appear in the priority canvas, the add-slot picker
(labelled ' (image)'), and the key scope dialog.
handleImage recorded the raw request model id, so AUTO image
generations showed up as model=AUTO in the request records and
by-model aggregates instead of the image model actually served
(e.g. Kwai-Kolors/Kolors).
UnifiedResponse gains an optional Model field; Provider.Image fills
it with the resolved id (AUTO resolves to the source's best image
model), and handleImage prefers it when writing the audit record.
6 call sites used the fetch default GET while sending a request body,
which browsers reject outright ('Request with GET/HEAD method cannot
have body'). Affected flows: create key, save source, save auto rules,
upload adapter, update key model scope, and /api/chat streaming.
All now send the method their backend handlers require (POST or PUT)
with an explicit Content-Type.
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.
Live testing across the zen pool showed models report
prompt_tokens_details.cached_tokens even when the hit count is 0 (e.g.
nemotron-3-ultra-free returns cached_tokens:0, audio_tokens:0,
cache_write_tokens:0). The previous >0 guard dropped those objects, so a
cache-enabled upstream looked identical to one without cache support.
- types: PromptTokensDetails.CachedTokens always emitted (drop inner
omitempty) so clients see cached_tokens:0 explicitly; dsh reads it as
a 0% hit instead of 'no data'
- adapters (9): forward prompt_tokens_details whenever the upstream
provides it (presence check instead of >0)
- Req: add cache_reported flag set when usage carried cache accounting;
WebUI shows an amber 0% tag for reported-but-missed rows and keeps
the em-dash only for sources that never report cache data
Live testing proved both sensenova and zen DO return cache fields:
- zen laguna-s-2.1-free: usage.prompt_tokens_details.cached_tokens = 32
(real hit), plus cache_write_tokens/audio_tokens
- sensenova glm-5.2: prompt_tokens_details.cached_tokens present (0 on
short prompts)
The previous round only patched deepseek/openai/anthropic/gemini.lua;
sensenova/opencode (localzen!) and the other adapters still dropped them.
- sensenova/opencode/groq/mistral/github/kimicode: stream + response
cache passthrough (same pattern as openai.lua)
- agentrouter: response passthrough + NEW stream usage forwarding (it
previously dropped the terminal usage-only chunk entirely)
- ollama skipped intentionally: its native API has no cache fields
Verified end-to-end through the gateway: localzen/laguna-s-2.1-free now
returns prompt_tokens_details.cached_tokens=32 to clients, and the request
record carries cache_hit_tokens (both chat and stream paths).
- Req: add CacheHit and CacheMiss fields (carrying upstream cache
accounting from either prompt_tokens_details.cached_tokens or legacy
prompt_cache_hit_tokens)
- recordChatUsage (non-streaming): copy cache fields from resp.TokenUsage
- pumpStream (streaming): write lastUsage cache fields back onto rec at
stream end, so streaming requests carry cache data too
- CSV export: add first_byte_ms, cache_hit_tokens, cache_miss_tokens
columns alongside the existing latency/prompt/completion
- WebUI request-records table: add a Cache column showing hit% per row
(green/amber tag with tooltip hit/miss breakdown; em-dash when the
upstream reported no cache data)
- 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
When only the legacy DeepSeek fields (prompt_cache_hit_tokens) are set but
the OpenAI-standard prompt_tokens_details is nil, MarshalJSON now auto-
generates the nested object. This ensures dsh (which reads the standard
format first) sees cache hit data regardless of which adapter format the
upstream uses.
dsh displays cache-hit %, but llmsproxy dropped every upstream's cache
fields — deepseek prompt_cache_hit_tokens, OpenAI prompt_tokens_details.
cached_tokens, anthropic cache_read_input_tokens, gemini cachedContentTokenCount.
Changes:
- TokenUsage: add PromptTokensDetails (with CachedTokens) + PromptCacheHit/Miss
- MarshalJSON: emit prompt_tokens_details.cached_tokens (OpenAI v2 standard)
and prompt_cache_hit/miss_tokens (DeepSeek legacy) — dsh reads the former
first, falls back to the latter
- mergeUsage: preserve cache fields across stream chunks
- standardSSEChunk: parse the upstream raw prompt_tokens_details too
- deepseek.lua: forward prompt_cache_hit/miss_tokens + create
prompt_tokens_details from them
- openai.lua: forward prompt_tokens_details.cached_tokens and legacy
prompt_cache_hit/miss_tokens; normalize legacy hits into the standard
object so dsh sees them regardless of upstream format
- anthropic.lua: map cache_read_input_tokens → prompt_tokens_details
- gemini.lua: map cachedContentTokenCount → prompt_tokens_details
WebUI (internal/gateway/ui):
- BUG: the export modal's custom-range button called
downloadStatsCsvFromForm() which was never defined — clicking it threw a
ReferenceError and nothing downloaded. Implement it: reads #exp-from /
#exp-to date inputs and forwards to downloadStatsCsv.
- BUG-adjacent: clearChat() existed but was reachable from no control —
add a Clear button to the chat composer so conversation reset is actually
possible (+ cClear i18n zh/en).
- remove byte-identical duplicate html[data-theme=dark] CSS block (15 lines)
- remove 8 dead CSS rules (.keys-grid .m-model-row .scope-add/.scope-box/
.scope-chips .scr-blocks .tag-warn .twrap) and the never-consumed
--accent custom property
- remove 3 dead JS functions (activeTab/findSlots/scopeUncomb; lastTab decl kept)
- remove 24 dead i18n keys x zh/en (~55 lines) — legacy of the replaced
key-scope editor, matching the removed .scope-* styles
GUI (cmd/gui/main.js):
- BUG: stopCore() set app.isQuitting=true and nothing reset it — after using
tray 'stop core', closing the window quit the whole app instead of hiding
to tray, and core crash auto-restart stayed disabled. isQuitting now only
flips in restartCore (scoped) and before-quit.
Verified: go vet/test green; node --check on all three GUI js files and the
WebUI inline script.
- extract csvHeaders() (Content-Type + Content-Disposition) shared by both
export branches
- extract exportKey(): the identical admin/user key-filter logic existed
twice (JSON path + keys-csv); now all three call sites share one function
- inline the nine single-use intermediate variables in the keys-csv loop
singleChat / singleChatAuto / streamChat / streamChatAuto shared ~260 near-
identical lines (diff after stripping comments was empty). Extract three
shared bodies and shrink all four entry points to thin dispatchers:
- failChat: error → record + writeError, shared ChainErr extraction
(errors.As returns false for direct-path errors, so the two paths stay
equivalent without a branch)
- recordChatUsage: exact upstream numbers win, byte estimates fill gaps
- writeChatCompletion: unified ChatCompletion rendering (model name is the
only direct/auto difference, passed in)
- pumpStream: the full SSE pump (preamble, delta loop, terminal finish +
usage chunk, [DONE]) — shared by both streaming entries
Behavior change (pinned by TestDirectStreamFailoverAuditSource): direct
streams now pin rec.Source to the source that actually served the stream
after a failover, instead of discarding it (_, usedModel). The audit row
previously recorded the first candidate, which was wrong on failover.
chat.go: 982 → 896 lines (−86).
provider.oneLineStr and gateway.oneLine had byte-identical bodies (flatten
whitespace + cap length). Move the single implementation into the types
package, which both layers already depend on, and delete both locals.
- provider.truncate: zero callers (oneLineStr is the used superset)
- gateway.normalizeModel: zero callers
- config.resolvedAPIKey: zero callers (core.resolveSourceKey is the live equivalent)
- Stats.Records: zero callers (CSV export uses AuditRecords)
- store.containsString: zero callers
- Config.MaxConcurrent: global inflight-cap field never read; per-source
MaxConcurrent is what actually drives semaphores. Legacy configs carrying a
top-level max_concurrent key still load (yaml.v3 ignores unknown fields —
verified by test).
- gui renderer esc(): zero callers; renderer uses textContent, and the embedded
WebUI has its own esc()
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.
Every upstream formats errors differently, which is adapter territory:
the protocol gains an optional transform_error(status, body) hook and all
built-in adapters implement their own envelope parsing (zen free-pool
labels, anthropic/gemini/ollama/mistral shapes, sensenova quota notes,
agentrouter WAF pages). The core keeps a single uniform fallback: when no
hook yields a reason clients get "api error <status>: unknown error" and
the raw body goes to server logs only.
api error strings embedded raw upstream response bodies, so JSON quota
payloads and WAF HTML pages leaked through to clients (and through the
per-tier chain summary). shortAPIError extracts the envelope reason
(error.message / message / msg), collapses HTML blocklist pages to a
marker, and caps everything at one line.
WindowTokens buckets are whole unix hours, so a fixture built from raw
offsets like "1 minute ago" landed in the previous hour bucket whenever
the suite ran in the first minute of an hour — the 1h-window assertion
then saw 0 tokens and failed. Anchor rows to hour boundaries instead
(H-2 / H-1 / current bucket) and assert the exact current-bucket value;
the suite is now deterministic for any run time.
Clients saw the full per-tier chain error including upstream HTML WAF
pages and JSON quota payloads. The response now carries one capped
one-line reason per tier (quota/cooling skips preserved); full detail
remains in rec.Err / stats API and is logged server-side.
Some upstreams (zen free pool) answer HTTP 200 with a single-chunk stream
whose only payload is finish_reason:"network_error" and an empty delta.
ChatStream used to hand that channel up as a success, so clients received
a laundered empty reply (agents ended their turn mid-loop) and the broken
slot kept its scheduling preference. ChatStream now holds back the first
chunk: an error-only done chunk fails the candidate before any byte
reaches the gateway, letting the scheduler fall through to the next
source. Standard finish reasons (including instant-empty "stop") are never
classified as errors.
The gateway hardcoded "stop" on every terminating stream chunk, so
tool-call rounds reported finish_reason=stop and length caps were
invisible to clients. UnifiedChunk now carries finish_reason; adapters
emit it (with empty-string finish reasons like sensenova treated as
non-terminal), standardSSEChunk passes it through for un-adapted
upstreams, [DONE] no longer emits a duplicate reason-less done chunk,
and both streaming paths emit the real reason with "stop" as fallback.
Also vendor sensenova/agentrouter adapters into the repo: they were
WebUI-only uploads and a deploy sync silently removed them while live
AUTO-chain slots still referenced them.
zen fingerprints clients via UA + x-opencode-client/session/request/project
headers; requests without them are routed as anonymous and fail with a
single-chunk network_error stream (tools+stream) or 503 Endpoint is
unavailable (non-stream), which the adapter laundered into empty-but-valid
replies. Derive per-request session/request ids from build_headers meta
(sandbox has no os/math), bump UA to the real client format, map zen
reasoning field to reasoning_content, and set stream_options.include_usage.
The prior usage-passthrough fix only covered openai/opencode; the same
empty-choices+usage drop bug remained in the 5 sibling OpenAI-compatible
adapters, and non-OpenAI providers (anthropic/gemini/ollama) never surfaced
streaming usage at all.
- deepseek/github/groq/kimicode/mistral: preserve usage on empty-choices
chunks and attach it to normal chunks (same pattern as openai.lua)
- anthropic: emit usage from message_start (prompt) and message_delta
(completion); gateway merges split usage additively
- gemini: read usageMetadata in the stream path
- ollama: fix non-streaming key (usage -> token_usage, matches
UnifiedResponse json tag) and read prompt_eval_count/eval_count;
surface counts from the done stream chunk
- gateway: mergeUsage combines usage across chunks (non-zero fields win,
total recomputed from prompt+completion) so split usage doesn't lose
the prompt half; single-chunk case (OpenAI) preserved exactly
- usage-only chunks: done=false (no redundant terminal stop), matching
the Go fallback standardSSEChunk
Streaming responses now carry the upstream's real token usage instead of
gateway estimates:
- UnifiedChunk gains an optional Usage field; adapters (opencode, openai)
extract usage from upstream stream chunks (including the final chunk with
empty choices) and pass it through.
- standardSSEChunk preserves usage for passthrough adapters.
- Gateway emits the exact usage in the final stream chunk when available,
falling back to estimates only when the upstream provided none.
Non-streaming usage was already fixed to emit OpenAI-standard keys.
- TokenUsage.MarshalJSON now emits both standard (prompt_tokens,
completion_tokens, total_tokens) and legacy (prompt, completion, total)
keys, so OpenAI-compatible clients (DSH, DevEco Code, etc.) can read
token usage.
- ChatChunk gains an optional Usage field; stream responses now send a
final usage chunk (empty choices) before [DONE].
Refs: usage not visible in clients because the gateway serialized only the
internal short keys and never emitted a streaming usage chunk.
- 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)
opencode.ai/zen is a free-quota pool for the official opencode app, keyed by
User-Agent fingerprint. Auto-provisioning it in the default config effectively
impersonated the official client to bypass FreeUsageLimitError — a ToS risk.
- default config (Go + GUI embed) now ships NO sources; users add their own
- README/README_EN: remove opencode adapter from built-in list and the zen
free-pool paragraph
- adapter script and its unit tests stay (explicit opt-in only)
- adapters/opencode.lua: opencode.ai zen free pool adapter — sends the
opencode client User-Agent (zen fingerprints clients by UA; non-official
clients hit FreeUsageLimitError); pairs with api_key: public
- config: no config file ships in the repo; first run generates a default
config at the -config path with a random admin key, loopback listen and a
keyless zen source (config.EnsureDefault); remove config.example.yaml
- lua: seed bundled adapters from the embedded FS instead of a hardcoded
name list
- ui: widen model kind select (chat was clipped to 'cha')
- phase 5 bugfixes: stats ms/s bucket mixing, cleanScopes nil, ctx.Err
guards, direct-path ModelAvailable, empty stream body failure,
bestImageModel rewrite, transform failure recording, Core.mu, timer,
effective model for tool-calls
- Move all config (auto rules, keys) from runtime.json to config.yaml
- Store now only holds runtime sources (WebUI-created)
- Add OpenRouter free models to config.yaml
- One-time migration from legacy runtime.json on startup
- Fix gateway tests for new config structure
- Update core.go with migrateFromRuntime, saveConfig, seedKeys/seedAuto
- Remove SaveKey/KeyByValue/AutoRules from Store
- Add Config.Save() with YAML marshaling
- Update WebUI admin keys visibility (show all keys including admin)
- Bump binary to 11MB with luajit
The sidebar's backdrop-filter: blur() made the popup sidebar itself
unreadable on ≤900px screens. Disabled the blur in the responsive
media query; now sidebar has solid glass background and the
full-screen blur only applies to the backdrop behind it.
renderStatus() re-injected the entire status tab (#tab-status.innerHTML) + all charts + tables on every visit, so each tab switch back to home stuttered. Now the page is built once (pane.dataset.built) and revisits only reload live data via paintStats() + restart the 3s poll. Static parts (source table, model chips, connection box) are not rebuilt. Deployed (bak .bak.20260811y), server active.
- .kpi fixed height 206px was too short for the tokens card (hdr + big value + two-line in/out + chart + legend) -> text overflowed; bumped to 252px with legend capped at max-height/scroll
- tokens chart: stack shows top-4 slices + lumped 'other', total uses the FULL model set (true shares, was relative to top-4); legend lists every model that has non-zero tokens (was hardcoded top-4, so small/zero slices were dropped -> 'only two models' visible)
- add kOther zh/en
- deployed (bak .bak.20260811x), server active
Previously the skeleton was a fixed 186px but the real cards had different natural heights (status pie 110 + legend, tokens two-line sub + legend, etc.), so replacing the skeleton caused a size jump. Now every .kpi is a fixed 206px flex column; .k-chart absorbs the remaining space (flex:1) and the canvas absolutely fills it (draw fns read container height, not a hardcoded 86/110). Skeleton .ksk is exactly 206px with the same layout, so first paint and real cards are identical in size. Deployed (bak .bak.20260811w), server active.
- KPI skeleton (.ksk) min-height now matches the real card (186px) with a title/value/chart bar layout so first paint doesn't jump
- global entry animations: cards fade+slide-up (fadeUp), tab panes fade+rise (tabIn), chat empty state fades in
- goTab restarts the tabIn animation on switch (reset animation + forced reflow)
- table-row animation intentionally NOT added (those re-render every 3s poll and would flicker)
- deployed (bak .bak.20260811v), server active
The five KPI cards are built only after /api/stats returns; before that #kpi-row was empty, so the top of the dashboard appeared blank then jumped in. Now the row starts with a shimmer skeleton (5 placeholder cards with a CSS gradient animation) that paintStats replaces with the real cards on first data. Deployed (bak .bak.20260811u), server active.
paintStats() rewrote #kpi-row innerHTML on every 3s refresh, destroying/recreating all five cards + canvases each time -> each poll flashed. Now the card structure is built once (dataset.built guard) and subsequent polls only update the value text (data-kpi attrs) and redraw the canvases. Preserves colored success rate and two-line in/out tokens. Deployed (bak .bak.20260811t), server active.
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.
- chat tab model select: list each model grouped by source as 'source · model' with value 'source:model' (the unambiguous pin syntax — all 18 real models contain '-' but none contain ':'), so same-named models on different sources are distinguishable in tests; falls back to flat model list for non-admin (sources not exposed)
- tokens card: remove on-chart text, add color-swatch legend (#tb-tokens-legend) mapping bar color -> model; in/out tokens on separate lines (.k-sub.k2)
- deployed (bak .bak.20260811r), server active
The center 'hole' was faked by overpainting a small circle with var(--card), which exposed a yellow/warm card background blob and a visible seam. Now each slice is a real ring sector (outer+inner arc, reverse) so the center is genuinely transparent and matches the card. Deployed (bak .bak.20260811p), server active.
