dashboard: skip DOM rebuild on unchanged poll, publish-time staleness, fix boundary countdowns

poll() now compares raw payload text and re-renders only what a changed
file can affect, preserving selection, disclosure, and scroll state. Hero
freshness reflects publish time (STALE warning past 15 min while market
open), and countdowns resolve their wrap interval from data-interval
instead of reverse-looking shared TF boundaries in snapshot.timeframes.

+MULTI-PROVIDER LLM LAYER - PLAN
+(DeepSeek for news summary, Anthropic Claude for agent panel)
+Written 2026-08-08. Plan only - no code has been changed.
+================================================================================
+
+WHY
+---
+Today every LLM feature (news enrichment + agent panel) goes through one
+hardwired client: llm_client.py -> DeepSeekClient, a module singleton reached
+via get_llm_client(). This plan describes how to route different features to
+different providers - e.g. keep DeepSeek for cheap high-volume news scoring,
+put the agent panel on Anthropic Claude for better reasoning.
+
+The repo already solved this problem once for market data: the providers/
+package (BaseDataProvider owns shared machinery, subclasses implement only
+_fetch_raw, a registry + one config knob selects the provider). This plan
+mirrors that proven pattern at the LLM layer, scaled down to a single module.
+
+BLAST RADIUS (verified by grep)
+-------------------------------
+get_llm_client() call sites:
+  - news_engine.py ....... 4 sites
+  - agent_panel.py ....... 3 sites (+1 timeout getattr)
+  - telegram_bot.py ...... 1 site (/status health; reads private _count,
+                           _count_day, _daily_cap fields)
+  - test_all.py .......... 41 locations stub via  lc._client = _StubLLM(...)
+Out of scope: static/news_summary.php (own PHP DeepSeek call + key file,
+separate deployment).
+
+DESIGN INVARIANTS (carried over unchanged)
+------------------------------------------
+1. Fail-safe contract: every call returns Optional[Dict]; any failure -> None;
+   callers keep their non-LLM fallbacks; LLM output never gates signals.
+2. Single attempt, no retries (news cache cadence is the retry); per-provider
+   UTC daily cap; warn-once logging; health stamps (last_ok, last_error).
+3. Static system prompts stay byte-identical constants - provider-neutral,
+   and they map to prompt caching on BOTH providers (DeepSeek prefix cache;
+   Anthropic cache_control ephemeral).
+4. Test compatibility: all 41 existing lc._client stub sites keep working
+   with zero edits.
+
+================================================================================
+1. llm_client.py REFACTOR  (~195 -> ~430 lines, no new files)
+================================================================================
+
+1a. BaseLLMClient - shared machinery (extracted from today's DeepSeekClient)
+    - __init__(api_key, model, timeout, daily_cap, enabled)
+    - public: name ("deepseek"/"anthropic"), timeout property,
+      usage() -> (used_today, cap)   # so telegram_bot stops reading privates
+    - owns: available property, _warn_once, _under_cap() (UTC-day counter,
+      lock), health stamps, and the template method:
+
+        def chat_json(self, system_prompt, user_payload):
+            if not self.available or not self._under_cap():
+                return None
+            try:
+                return self._request(system_prompt, user_payload)  # hook
+            except <provider-agnostic error mapping>:
+                # stamps last_error, returns None
+
+    - subclasses implement ONLY _request(system_prompt, payload) -> dict|None.
+
+1b. DeepSeekClient(BaseLLMClient) - behavior-identical move
+    Current requests-based logic relocates into _request: same URL,
+    thinking:disabled, response_format:json_object, temperature 0,
+    max_tokens 2000, sort_keys=True payload, _parse_response.
+    Review criterion: Module 19 tests pass UNMODIFIED (they patch
+    client._session, which stays).
+
+1c. AnthropicClient(BaseLLMClient) - new, official SDK
+    - Official `anthropic` Python SDK (add to requirements.txt), NOT raw
+      requests. LAZY IMPORT inside __init__: package missing -> warn-once +
+      client unavailable, so DeepSeek-only deployments never install it.
+    - Constructor: anthropic.Anthropic(api_key=..., timeout=<configured>,
+      max_retries=0)   # house rule: single attempt
+    - _request:
+        resp = self._client.messages.create(
+            model=self._model,                  # default "claude-opus-5"
+            max_tokens=4000,                    # covers thinking + JSON reply
+            output_config={"effort": "low"},    # cheap structured takes
+            system=[{"type": "text", "text": system_prompt,
+                     "cache_control": {"type": "ephemeral"}}],
+            messages=[{"role": "user",
+                       "content": json.dumps(user_payload, sort_keys=True)}],
+        )
+        if resp.stop_reason == "refusal":       # Opus 5: HTTP 200, check first
+            return None
+        text = first text block in resp.content
+        return self._parse_json(text)   # tolerant: strip ```json fences,
+                                        # json.loads, dict check
+    - DELIBERATELY ABSENT (would 400 on Claude Opus 5): temperature (removed
+      on Opus 5 - do NOT copy from the DeepSeek client), budget_tokens,
+      prefills, response_format.
+    - Error mapping: APIConnectionError -> "network",
+      APIStatusError -> "http_<code>", parse fail -> "parse"
+      (same last_error kinds the /status display already understands).
+    - Defaults: model claude-opus-5 (config-overridable, e.g. claude-haiku-4-5
+      for ~5x cheaper), timeout 30s (Claude slower than V4-Flash), own
+      daily_request_cap 500.
+
+1d. Registry + per-consumer routing
+        _PROVIDERS = {"deepseek": DeepSeekClient, "anthropic": AnthropicClient}
+        LLM_CONSUMERS = ("news", "agent_panel")
+        _clients = {}     # keyed by PROVIDER name -> two consumers on the
+                          # same provider share one instance and one cap
+        _client = None    # kept: GLOBAL TEST OVERRIDE
+
+        def get_llm_client(consumer="news"):
+            if _client is not None:          # tests: lc._client = stub
+                return _client               #   -> shadows ALL consumers
+            name = get_app_config().llm_routing.get(consumer, "deepseek")
+            create-once per provider, return _clients[name]
+
+        def reset_llm_client():              # clears _client AND _clients
+
+    Keeping _client as a documented test-override global is what makes the
+    41 existing stub sites work untouched.
+
+================================================================================
+2. CONFIG  (app_config.py + config.json.example)
+================================================================================
+- New top-level "anthropic" block, mirroring "deepseek":
+    {api_key, model, enabled, timeout_seconds, daily_request_cap}
+  plus anthropic_api_key() resolver: ANTHROPIC_API_KEY env -> config.json -> "".
+- New top-level "llm" ROUTING block:
+    {"news": "deepseek", "agent_panel": "deepseek"}
+  Validation: keys within {news, agent_panel}; values within registered
+  provider names. Absent block -> {} -> everything on DeepSeek (today's
+  behavior; zero-migration default). AppConfig.llm_routing: Dict[str, str].
+
+- The target state is then PURE CONFIG - no code changes on switch day:
+
+    "llm":       { "news": "deepseek", "agent_panel": "anthropic" },
+    "anthropic": { "api_key": "", "model": "claude-opus-5", "enabled": true,
+                   "timeout_seconds": 30, "daily_request_cap": 500 }
+
+================================================================================
+3. CONSUMER EDITS  (mechanical, ~10 lines total)
+================================================================================
+- news_engine.py:  4 call sites -> get_llm_client("news")
+- agent_panel.py:  3 call sites -> get_llm_client("agent_panel");
+                   getattr(client, "_timeout", ...) -> public client.timeout
+- telegram_bot.py _news_health_lines: iterate the DISTINCT providers actually
+  routed (news + panel); per provider print "<name>: used/cap calls today"
+  via the new usage() accessor instead of private fields. DeepSeek keeps its
+  "headlines scored" extra; cap/error warnings work off base-class stamps.
+- NO changes to prompts, payload builders, caches, or the panel's own
+  max_panels_per_day budget - all provider-agnostic already.
+
+================================================================================
+4. TESTS  (new "Module 24: LLM provider routing", ~12 tests, ~200 lines)
+================================================================================
+Reuse _StubLLM; new _FakeAnthropic (fake messages.create returning a stub
+response object) injected as client._client.
+
+ 1. app_config: anthropic block parses/validates/defaults empty.
+ 2. app_config: llm routing block - valid map round-trips; unknown consumer
+    key, unknown provider name, non-dict -> AppConfigError; absent -> {}.
+ 3. anthropic_api_key resolves env -> config.json -> empty.
+ 4. Base contract on BOTH subclasses (parametrized): keyless/disabled -> no
+    call; daily cap blocks + UTC-roll reset; failure stamps last_error,
+    success stamps last_ok.
+ 5. AnthropicClient parse: clean JSON -> dict; ```json-fenced -> dict;
+    non-JSON -> None; stop_reason "refusal" -> None; no text block -> None.
+ 6. AnthropicClient request shape: NO temperature key, max_retries=0,
+    cache_control present on system block (assert on captured kwargs).
+ 7. AnthropicClient with `anthropic` package missing (simulated) ->
+    available False, chat_json None, no crash at import.
+ 8. Routing: no llm block -> both consumers get the SAME DeepSeek singleton
+    (shared cap); routed config -> news gets DeepSeekClient while
+    agent_panel gets AnthropicClient; same-provider consumers share one
+    instance.
+ 9. Global lc._client override shadows BOTH consumers (locks the 41 legacy
+    stub sites' semantics).
+10. reset_llm_client() clears both the override and the per-provider cache.
+11. End-to-end: routing agent_panel->anthropic, attach_panel reaches the
+    anthropic fake (5 calls) while a news call reaches the deepseek stub.
+12. telegram _news_health_lines renders per-provider lines from usage()
+    without touching private fields.
+
+GATE: Modules 19 and 23 must pass UNMODIFIED - the no-regression proof for
+the refactor.
+
+================================================================================
+5. DOCS
+================================================================================
+- CLAUDE.md: llm_client bullet -> provider-abstracted (BaseLLMClient;
+  deepseek + anthropic registered); config.json "llm" block routes consumers;
+  absent = all-DeepSeek. Add ANTHROPIC_API_KEY to env-var list. Test counts.
+- config.json.example: both new blocks.
+
+================================================================================
+COMMIT SEQUENCE  (each commit green)
+================================================================================
+1. llm_client: extract BaseLLMClient; DeepSeekClient unchanged behavior
+   (+ base-contract tests)  - pure refactor, Modules 19/23 green untouched.
+2. config: anthropic block + llm consumer-routing block (+ config tests).
+3. llm_client: AnthropicClient (official SDK, lazy import) + requirements.txt
+   (+ parse/shape tests).
+4. routing: per-consumer get_llm_client + health lines - consumer call-site
+   edits, telegram usage() lines, routing/e2e tests.
+5. docs: CLAUDE.md + example config.
+
+================================================================================
+VERIFICATION
+================================================================================
+- python test_all.py green at every commit (~374 -> ~386).
+- Live smoke A (no behavior change): default config, main.py --panel ->
+  still DeepSeek, /status unchanged.
+- Live smoke B (the goal): llm.agent_panel="anthropic" + real
+  ANTHROPIC_API_KEY, run --panel -> one real Claude panel (5 requests,
+  validates JSON contract + latency + refusal-free path) while a news
+  refresh still hits DeepSeek; /status shows two provider lines.
+- Backtest untouched by construction (no LLM in replay path); one 30-day
+  run as a formality.

+
+================================================================================
+KEY DECISIONS EMBEDDED IN THIS PLAN
+================================================================================
+- Official Anthropic SDK, not raw requests (current API guidance for Python;
+  lazy import keeps it optional for DeepSeek-only installs).
+- Default Claude model: claude-opus-5 ($5/$25 per MTok; a full 5-call panel
+  ~ 8k in / 500 out ~ $0.05). Config-overridable to claude-haiku-4-5.
+- Two Claude gotchas handled: temperature is REMOVED on Opus 5 (sending it
+  400s - must not be copied from the DeepSeek request body), and refusals
+  arrive as HTTP 200 with stop_reason "refusal" (checked before parsing,
+  mapped to the normal None/fallback path).
+- Caps are per-provider, not per-consumer: two consumers on one provider
+  share its cap (today's semantics); splitting across two providers doubles
+  total headroom naturally.
+- The panel's own max_panels_per_day budget is untouched - it sits above
+  whichever provider serves it.
+- Not in scope: static/news_summary.php (own PHP client/key), streaming,
+  tool use, per-consumer model overrides (add a "model" key per consumer
+  later if ever needed).
