and using explicit close in both success and error paths

- serializeMessages: preserve ToolCallID/ToolCalls when Media is present

- Remove stale "falls back to plain text" comment on Send
- Add empty ChatID validation in SendMedia to match Send
- Use messageID+fileKey as local filename to avoid write collisions
- Check allowlist before downloading inbound media to avoid wasted I/O
- Return errUnsupported consistently from all 32-bit stub methods
Upgrade the Feishu channel from basic text-only to full feature parity with
Telegram/Discord: interactive card messages with markdown rendering, message
editing (MessageEditor), placeholder messages (PlaceholderCapable), emoji
reactions (ReactionCapable), and inbound/outbound media support (MediaSender).
Also add @mention detection with lazy bot open_id discovery, group trigger
filtering with mention awareness, and multi-type inbound message parsing
(text, post, image, file, audio, video).
- Use atomic.Bool for closed flag to prevent TOCTOU race between
CallTool and Close operations
- Add double-check pattern in CallTool for thread-safe closed state
- Use atomic Swap in Close to ensure no new calls can start after
closed flag is set
- Move MCP manager cleanup defer before initialization to handle
partial initialization failures
- Update tests to use atomic.Bool operations

The previous dedupe map rotation logic completely cleared the map when it reached max size, causing an 'amnesia cliff' where immediately arriving duplicates of just-forgotten messages would be processed.
This change replaces that with a MessageDeduplicator struct that uses a circular queue (ring buffer) to track insertions. When the limit is reached, it only evicts the absolute oldest message from the map, completely resolving the cliff issue.
This also cleans up the WeCom Bot and App webhook handlers by encapsulating the mutex and map state.
When the dedupe map rotates, the previous logic entirely cleared the map, meaning the message that triggered the rotation was immediately forgotten and could be duplicated immediately.
This change seeds the new map with the current message to prevent that. Also adds a defensive nil check.
Match rotation semantics to prior behavior by fully resetting the dedupe map
once the size limit is exceeded, and add focused tests for duplicate detection
and boundary rotation behavior.
Centralize dedupe map access behind a mutex-safe helper and use it in both
WeCom bot and WeCom app channels to eliminate concurrent map access races while
preserving current dedupe behavior.
- classifier.go: s/honour/honor/ (American English per misspell)
- router.go: break SelectModel signature across lines (golines)
- router_test.go: break long Message literal (golines)
- router_test.go: replace CJK string literal with rune slice so
gosmopolitan does not flag the source file; behaviour is identical
instance.go:
- Add Router *routing.Router and LightCandidates []FallbackCandidate
to AgentInstance.
- At agent creation, when routing.enabled and light_model resolves
successfully in model_list, pre-build the Router and resolve the
light model candidates once. If the light model isn't in model_list,
log a warning and disable routing for that agent gracefully.
loop.go:
- Add selectCandidates(agent, userMsg, history) helper.
It calls Router.SelectModel and returns either agent.Candidates /
agent.Model (primary tier) or agent.LightCandidates / light_model
(light tier). Returns primary unchanged when routing is disabled.
- In runLLMIteration, resolve (activeCandidates, activeModel) once
before entering the tool-iteration loop. The model tier is sticky
for the entire turn so a multi-step tool chain doesn't switch
models mid-way.
- Replace hard-coded agent.Candidates / agent.Model references in
callLLM and the debug log with the resolved active values.
The fallback chain and retry logic are untouched. When light_model
returns an error the fallback chain handles escalation normally.
Add three new files to pkg/routing/:
features.go — ExtractFeatures(msg, history) → Features
Computes five structural dimensions with zero keyword matching:
- TokenEstimate: rune_count/3 (CJK-safe token proxy)
- CodeBlockCount: ``` pairs in the message
- RecentToolCalls: tool call count in the last 6 history entries
- ConversationDepth: total messages in session
- HasAttachments: data URIs or media file extensions
classifier.go — Classifier interface + RuleClassifier
RuleClassifier uses a weighted sum that is capped at 1.0:
code block → +0.40 (triggers heavy model alone at 0.35 threshold)
token > 200 → +0.35 (triggers heavy model alone)
tool calls > 3 → +0.25
token 50-200 → +0.15
conversation depth > 10 → +0.10
attachment → 1.00 (hard gate, always heavy)
router.go — Router wraps config + Classifier
Router.SelectModel(msg, history, primaryModel) returns either the
configured light_model or the primary model depending on whether
the complexity score clears the threshold. Threshold defaults to
0.35 when zero/negative to prevent misconfiguration.
router_test.go — 34 tests covering all branches and edge cases
Introduce RoutingConfig with three fields:
- enabled: activates per-turn model routing
- light_model: references a model_name in model_list
- threshold: complexity score cutoff in [0,1]
When routing.enabled is true and the incoming message scores below
threshold, the agent switches to light_model for that turn. Absent or
disabled config leaves existing behaviour completely unchanged.
Example:
"agents": {
"defaults": {
"model": "claude-sonnet-4-6",
"routing": {
"enabled": true,
"light_model": "gemini-flash",
"threshold": 0.35
}
}
}
Without this function, media:// refs stored by MediaStore are passed
directly to the LLM API, which rejects them as invalid URLs.
resolveMediaRefs() runs after BuildMessages() and before the LLM call,
converting each media:// ref to a data:image/...;base64,... URL that
vision-capable models can process.
Also adds mimeFromExtension() helper for MIME type inference from
file extensions when ContentType metadata is not available.
