harden(dataflows): bound the Reddit feed read before parsing

- ElementTree does not resolve external entities, so the reported XXE flag
  doesn't apply; the real residual is an unbounded read of untrusted network XML
- cap both the RSS and JSON reads at 5 MiB; overflow degrades to empty / RSS
  fallback through the existing failure paths #1206 #1276

+## [0.4.0] — 2026-08-31
+
+Look-ahead and point-in-time fixes across the data and memory layers, clearer
+decision signals, working CLI checkpoint resume, and the GPT-5.6 / GLM-5.3 models.
+
+### Fixed
+
+- **FRED macro look-ahead.** Historical macro requests were served from today's
+  data vintage, leaking later revisions into a backtest; both the observations
+  and metadata requests now pin the vintage to the as-of date. (#1275)
+- **Social sentiment look-ahead.** StockTwits and Reddit were fetched with no
+  date, so a historical run showed today's chatter as if it were from the as-of
+  date; the social path is now trimmed to the analysis window, via one shared
+  UTC half-open window rule (`dataflows/date_window`) used by news too. (#1220)
+- **Memory point-in-time guard.** `get_past_context` returned every resolved
+  lesson regardless of the run date; each resolved entry now records the date
+  its outcome became known, and a historical run only sees lessons resolved by
+  the trade date. (#1251)
+- **Premature reflection.** A decision was settled on a partial return if a rerun
+  happened before its holding window fully traded; resolution now waits for the
+  full window. (#1169)
+- **Latest OHLCV bar dropped.** The newest bar with a NaN close was silently
+  dropped before the date cutoff, making the previous trading day look like the
+  latest; dates are normalized per element (DST- and non-US-market safe) and a
+  missing latest close raises rather than falling back. (#1201)
+- **Debate opening fabrication.** The first speaker in each debate round rebutted
+  an empty opponent response, fabricating the other side; all five debators now
+  open with their own case when no opponent has spoken. (#1176)
+- **Silent Hold.** An unparseable Portfolio Manager rating (including a fullwidth
+  colon) was coerced to a tradeable Hold; it now surfaces a `REVIEW` sentinel,
+  with `parse_rating` keeping its silent default for compatibility callers. (#1170)
+- **`--checkpoint` was a no-op on the CLI.** Checkpoint setup lived only in
+  `propagate()`; the CLI streamed the checkpointer-less graph. The lifecycle is
+  now shared, and a resume feeds `None` so LangGraph continues the interrupted
+  run instead of duplicating messages. (#1249)
+- **DeepSeek via OpenRouter.** `deepseek/<id>` fell through to default
+  capabilities and had object-form `tool_choice` forced on it; the official
+  namespace is stripped so it reuses the native DeepSeek quirks. (#1199)
+- **Trader price grounding.** The Trader saw only the digested plan; it now also
+  receives the technical market report so entry/stop levels anchor to real price
+  structure. (#1167)
+
+### Added
+
+- **Configurable output-token cap.** `max_tokens` / `TRADINGAGENTS_MAX_TOKENS`,
+  forwarded to every provider (Gemini as `max_output_tokens`), so a model that
+  emits unbounded reasoning can be bounded instead of hanging. (#1204)
+- **Latest models.** Added the GPT-5.6 family (`gpt-5.6` / `gpt-5.6-terra` /
+  `gpt-5.6-luna`) and GLM-5.3 (`glm-5.3`, `glm-5.3-flash`). The default models
+  are now `gpt-5.6` (deep) and `gpt-5.6-luna` (quick).

+
+## [0.3.1] — 2026-07-05
+
+Correctness and stability patch: data look-ahead, graph-router crash-safety,
+checkpoint identity, crypto sentiment sources, and configurable resilience.
+
+### Fixed
+
+- **Alpha Vantage look-ahead filter now runs.** The fundamentals payload is a
+  JSON string, so the dict-only guard skipped filtering and future-dated reports
+  leaked into historical runs; parse before filtering. (#1115, @zachthebird)
+- **News analyst prompt matches the tool.** The prompt advertised
+  `get_news(query, ...)` but the tool takes a ticker; aligned to stop
+  hallucinated free-text query calls. (#1116, @shcheuk)
+- **Shared debate/risk routers can't crash mid-run.** Both routers return more
+  targets than any one edge mapped; every edge now shares the complete path map,
+  so a fall-through under prompt/i18n/refactor drift stays routable.
+  (#1088, @Fr3ya, @sa7an7, @Sushanth012)
+- **Checkpoint resume respects graph shape.** The thread id folds in selected
+  analysts, debate/risk depth, and asset mode, so a resume under different
+  choices no longer continues the wrong graph. (#1089, @bossjoker1, @Ghraven)
+- **Crypto sentiment sources resolve.** StockTwits lists crypto as `<BASE>.X`
+  (Yahoo's `BTC-USD` 404s) and Reddit needs the base symbol to match; the social
+  path now maps crypto correctly for both. (#1113, @suremadoreai)
+
+### Added
+
+- **Configurable LLM retry budget.** `llm_max_retries` /
+  `TRADINGAGENTS_LLM_MAX_RETRIES` is forwarded to every provider, so a transient
+  429 burst no longer aborts a run. (#1091, @yanggaome)
+- **Bedrock API-key auth.** `AWS_BEARER_TOKEN_BEDROCK` authenticates Amazon
+  Bedrock without AWS access keys and takes precedence over an ambient
+  `AWS_PROFILE`. (#1103, @praxstack)
+- **Latest Claude models.** Added Claude Sonnet 5 (`claude-sonnet-5`) and
+  Fable 5 (`claude-fable-5`); effort control now covers the Claude 5 line.
+
+## [0.3.0] — 2026-06-22
+
+Stabilization and extensibility release: a CI gate, a unified verified
+data-access contract, a provider and data-vendor registry, and a maintenance
+sweep that hardened config precedence, the model catalog, data resilience, and
+structured output.
+
+### Added
+
+- **CI gate.** GitHub Actions runs the pytest suite across Python 3.10-3.13,
+  strict `ruff`, and a clean-install smoke that imports the package and CLI to
+  catch undeclared dependencies. (#994, #197)
+- **Provider registry.** OpenAI-compatible providers register as a single spec,
+  and a generic `openai_compatible` endpoint covers vLLM, LM Studio, and relays.
+  Adds NVIDIA NIM, Kimi, Groq, Mistral, and a native Amazon Bedrock client.
+- **Macro and prediction-market vendors.** FRED macro indicators and Polymarket
+  event probabilities, surfaced to the news and macro analysts.
+- **Programmatic report output.** `TradingAgentsGraph.save_reports()` writes the
+  same report tree the CLI produces, for headless and API runs. (#1037)
+- **Env-configurable reasoning depth** via `TRADINGAGENTS_OPENAI_REASONING_EFFORT`,
+  `TRADINGAGENTS_GOOGLE_THINKING_LEVEL`, and `TRADINGAGENTS_ANTHROPIC_EFFORT`,
+  each gated to the models that accept it.
+
+### Changed
+
+- **Verified data-access contract.** Symbol normalization on every vendor path
+  (identity, returns, CLI, news); the configured vendor list is the exact
+  resolution chain with no silent fallback to unselected vendors; a typed
+  `VendorError` taxonomy; look-ahead-safe news windows; stale-OHLCV rejection;
+  inclusive yfinance date ranges.
+- **Config precedence.** An explicit `TRADINGAGENTS_*` value or CLI flag now wins
+  over interactive defaults for debate and risk round counts,
+  `--checkpoint / --no-checkpoint`, and the Docker provider profile; invalid
+  boolean env values fail loudly. (#975, #976, #977)
+- **Current-generation model catalog.** Refreshed provider lineups; retired
+  `gpt-4.1`, Claude Sonnet 4.5, and the Gemini 2.5 line.
+- **Optional vendors degrade** instead of aborting a run: a failed macro or
+  prediction-market lookup returns a no-data sentinel.
+- **Analyst prompts lead with the current date** so tool-call date ranges anchor
+  to the run date rather than the model's training cutoff. (#836)
+
+### Fixed
+
+- **Instrument identity.** Deterministic ticker-to-company resolution prevents
+  wrong-company hallucination, and a verified market-data snapshot grounds price
+  and indicator claims. (#814, #830)
+- **Social and market data sources.** Reddit RSS-first with 429 backoff,
+  StockTwits transport hardening, and Alpha Vantage timeout plus
+  key-versus-rate-limit handling.
+- **Structured output.** Local OpenAI-compatible servers no longer reject
+  object-form `tool_choice`; a thinking model that returns no parsed result falls
+  back to free text; null-ish strings in optional price fields coerce to `None`.
+  (#1038, #1051, #1057)
+
+### Removed
+
+- The no-op `analyst_concurrency_limit` config knob; parallel analyst execution
+  is planned for a later release. (#979)
+- The unused committed `uv.lock`. (#1030)

+
+## [0.2.5] — 2026-05-11
+
+### Added
+
+- **Grounded Sentiment Analyst.** The renamed `sentiment_analyst` now reads
+  real Yahoo News, StockTwits, and Reddit data before generating its report,
+  replacing the prior flow that could fabricate social posts under prompt
+  pressure. (#557, #607)
+- **MiniMax provider** with the full M2.x catalog (M2.7 / M2.5 / M2.1 / M2
+  plus highspeed variants, 204K context). Dual-region: Global
+  (`MINIMAX_API_KEY`) and China (`MINIMAX_CN_API_KEY`).
+- **Dual-region Qwen and GLM** with separate keys per region — international
+  (`DASHSCOPE_API_KEY`, `ZHIPU_API_KEY`) and China (`DASHSCOPE_CN_API_KEY`,
+  `ZHIPU_CN_API_KEY`), selectable via a secondary region prompt. (#758)
+- **`TRADINGAGENTS_*` env-var configurability for `DEFAULT_CONFIG`.** Override
+  `llm_provider`, deep/quick model IDs, `backend_url`, `output_language`,
+  debate-round counts, checkpoint flag, and benchmark ticker via `.env` with
+  type-aware coercion (string / int / bool). (#602)
+- **Interactive API-key detection in the CLI.** When the selected provider's
+  key is missing, the CLI prompts for it and persists the value to `.env`
+  so the analysis run continues without restart.
+- **Remote Ollama support.** `OLLAMA_BASE_URL` points the CLI and the
+  programmatic client at a remote `ollama-serve`. The CLI surfaces the
+  resolved endpoint and warns on common malformed inputs. Adds a
+  `"Custom model ID"` option for models pulled via `ollama pull`. (#648, #768)
+- **Configurable news-fetch parameters** in `DEFAULT_CONFIG` — per-ticker
+  article limit, macro headline limit, lookback window, and macro search
+  queries. (#606, #683)
+- **Configurable alpha benchmark** for non-US tickers. Replaces hardcoded
+  SPY with regional indices for `.NS` (^NSEI), `.T` (^N225), `.HK` (^HSI),
+  `.L` (^FTSE), `.TO` (^GSPTSE), `.AX` (^AXJO), `.BO` (^BSESN); explicit
+  `benchmark_ticker` override available. Eliminates FX drift dominating
+  alpha for non-USD listings. (#628, #684)
+- **Multi-language output covers every user-facing agent** — researchers,
+  risk debators, research manager, and trader, ending the previous
+  partial-localization reports. (#575)
+- **Model catalog refresh.** OpenAI GPT-5.5 frontier, Anthropic Claude Opus
+  4.7, Gemini 3.1 Flash-Lite GA, xAI Grok 4.20, Qwen 3.6 line. Versioned IDs
+  only; auto-shifting aliases moved to the `"Custom model ID"` option.
+
+### Changed
+
+- **Sentiment Analyst** is now consistently named across the CLI dropdown,
+  status panel, and final reports (previously the backend was renamed but
+  the CLI still said "Social Analyst"). The `AnalystType.SOCIAL = "social"`
+  wire value is kept for saved-config back-compat.
+
+### Fixed
+
+- **Structured output works on DeepSeek V4 / reasoner and MiniMax M2.x.**
+  Those providers reject `tool_choice` per their tool-calling docs; the
+  binding flow now skips it automatically via a capability table.
+- **`pip install .` installations pick up the project `.env`** when running
+  the CLI as a console script. (#747)
+- **Reports save end-to-end** — streamed chunks were previously dropped from
+  `complete_report.md`. (#719, #736)
+- **Ticker prompt preserves exchange suffixes** (`.SH`, `.SZ`, `.SS`, `.HK`,
+  `.T`, etc.) for A-share, HK, Tokyo, and other non-US flows. (#770)
+- **Docker permission errors** no longer block first-run write to
+  `~/.tradingagents/`. (#519, #627, #672, #771)
+- **Config state no longer leaks between runs** when sub-dicts are mutated;
+  `set_config` partial updates preserve sibling defaults. (#788)
+- **`max_recur_limit` config actually applies** — previously read but not
+  forwarded to the propagator. (#764)
+- **Missing-API-key error** names the exact env var to set. (#680)
+- **Quieter startup** — suppressed the noisy upstream
+  `LangChainPendingDeprecationWarning` from langgraph-checkpoint; will be
+  removed once that package ships its fix.
+
+### Security
+
+- **Ticker path-traversal validation** at every filesystem-path site (cache,
+  checkpoint database, results) so a malicious ticker cannot escape its
+  intended directory. (#618)
+

 # TradingAgents: Multi-Agents LLM Financial Trading Framework
 
 ## News
-- [2026-04] **TradingAgents v0.2.4** released with structured-output agents (Research Manager, Trader, Portfolio Manager), LangGraph checkpoint resume, persistent decision log, DeepSeek/Qwen/GLM/Azure provider support, Docker, and a Windows UTF-8 encoding fix.

+## Reproducibility
+
+TradingAgents is LLM-driven, so two runs of the same ticker and date can differ. This is expected for a research tool built on language models, not a defect. The variation comes from a few distinct sources, and it helps to separate them.
+
+Language model sampling is non-deterministic. Even at a fixed temperature, providers do not guarantee byte-identical output across calls, and reasoning models (the default GPT-5.x family, and any thinking-mode model) vary the most because their internal reasoning is itself sampled.
+
+Live data moves. News, StockTwits, and Reddit return different content as time passes, so a run today sees different inputs than a run last week even for the same historical trade date. Pin the analysis date to hold the price and indicator window fixed, but the social and news sources still reflect "now".
+
+To reduce variation you can lower the sampling temperature. Set `temperature` in your config (or `TRADINGAGENTS_TEMPERATURE` in `.env`); lower values make models that honor it more repeatable. The current curated models are reasoning-first and largely ignore temperature, so for tighter reproducibility use a non-reasoning model, which you can set explicitly via the Custom model ID option.
+
+```python
+config = DEFAULT_CONFIG.copy()
+config["llm_provider"] = "openai"
+config["temperature"] = 0.0
+# Reasoning models ignore temperature. For tighter reproducibility, set a
+# non-reasoning deep/quick model explicitly (e.g. via the Custom model ID option).
+```
+
+What does not vary anymore: the analyzed company identity is resolved deterministically from the ticker before any agent runs, and the market analyst grounds exact price and indicator claims in a verified data snapshot. Earlier reports of "different companies" or fabricated price levels across runs are addressed by these two mechanisms.
+
+Backtest results are not guaranteed to match any published figure. Returns depend on the model, the temperature, the date range, data quality, and the sampling above. Treat the framework as a research scaffold for studying multi-agent analysis, not as a strategy with a fixed, replicable return.

+"""Sentiment analyst — multi-source sentiment analysis for a target ticker.
+
+Previously named ``social_media_analyst``. Renamed and redesigned because
+the old version had a prompt that demanded social-media analysis but the
+only tool available was Yahoo Finance news — which led LLMs to fabricate
+Reddit/X/StockTwits content under prompt pressure (verified live).
+
+The redesigned agent pre-fetches three complementary data sources before
+the LLM is invoked and injects them into the prompt as structured blocks:
+
+  1. News headlines     — Yahoo Finance (institutional framing)
+  2. StockTwits messages — retail-trader posts indexed by cashtag, with
+                           user-labeled Bullish/Bearish sentiment tags
+  3. Reddit posts        — r/wallstreetbets, r/stocks, r/investing
+
+The agent does not use tool-calling; the data is in the prompt from
+turn 0. Output uses the structured-output pattern (json_schema for
+OpenAI/xAI, response_schema for Gemini, tool-use for Anthropic), falling
+back to free-text generation for providers that lack native support, so
+the sentiment header (band + score + confidence) is deterministic across
+runs and providers instead of free-form per-model prose.

+
+## How to analyze this data (best practices)
+
+1. **Read the StockTwits Bullish/Bearish ratio as a leading retail-sentiment signal.** A 70/30 bullish/bearish split is moderately bullish; ≥90/10 may indicate over-extension and contrarian risk; 50/50 is uncertainty. Sample size matters — base rates on the actual message count, not percentages alone.
+
+2. **Look for cross-source divergences.** If news framing is bearish but StockTwits is overwhelmingly bullish, that mismatch is itself a signal — it can mean retail is leaning into a thesis the news flow hasn't caught up to (or vice versa, that retail is chasing while institutions are cautious).
+
+3. **Weight Reddit posts by engagement.** A 400-upvote / 200-comment thread reflects community attention; a 3-upvote post is noise. Read the body excerpts for context — the title alone often misleads.
+
+4. **Distinguish opinion from event.** A news headline ("Nvidia announces $500M Corning deal") is an event; a StockTwits post ("buying NVDA, this is going to moon") is opinion. Both are inputs but should be weighted differently in your conclusions.
+
+5. **Identify recurring narrative themes.** What topic keeps coming up across sources? That's the dominant narrative driving current sentiment.
+
+6. **Be honest about data limits.** If StockTwits returned only a handful of messages, or one or more sources returned an "<unavailable>" placeholder, the sentiment read is less robust — flag this explicitly in the `confidence` field and the narrative. If the sources are silent on a given subreddit, say so.
+
+7. **Identify catalysts and risks** that emerge across sources — news of upcoming earnings, product launches, competitive threats, macro headlines, etc.
+
+8. **Past sentiment is not predictive.** Frame your conclusions as signal for the trader to weigh alongside fundamentals and technicals, not as a price call.
+
+## Output fields
+
+Fill the following fields:
+
+- **overall_band**: Exactly one of Bullish / Mildly Bullish / Neutral / Mixed / Mildly Bearish / Bearish. Use Mixed when sources point in clearly different directions; Neutral only when all sources are genuinely silent.
+- **overall_score**: A number from 0 (maximally bearish) to 10 (maximally bullish); 5 is neutral. Keep it consistent with overall_band.
+- **confidence**: low / medium / high, based on data quality and sample size.
+- **narrative**: Full source-by-source breakdown, divergences, dominant narrative themes, catalysts and risks, and a markdown summary table of key sentiment signals (direction, source, supporting evidence).
