Subject: [PATCH 1/9] feat: add free-LLM sentiment tier above FinBERT/VADER

Vendor free_llm_router and layer an LLM sentiment tier on top of the existing
FinBERT -> XLM-RoBERTa -> VADER chain in processors/sentiment.py. The LLM returns
financial sentiment with direction (bullish/bearish), which keyword/FinBERT
scoring conflates with tone. Falls through to the existing chain on any failure,
so reliability is unchanged.

- Sync asyncio.run bridge (Celery workers have no running loop).
- Enabled by default when the package is present; FREE_LLM_ENABLED=false to disable.
- .env.example documents per-provider keys.

+Provider ordering policy — YOUR decision point.
+
+The router calls an ``OrderFn`` before every request to decide which provider to
+try first, second, third… Given a live snapshot of each provider's state, return
+the providers in the order you want them attempted.
+
+The default policy (``free_llm_router.router.default_order``) sorts by static
+``priority`` only. That's fine until reality intrudes:
+  * The top-priority provider is rate-limited *this minute* — trying it first just
+    wastes a failover hop (it'll be skipped, but it's still first in line).
+  * A provider has burned 49/50 of its daily quota — maybe save it for last.
+  * One provider has been consistently slow (high ``last_latency_ms``).
+  * A provider's circuit is half_open — risky; maybe deprioritize.
+
+`ProviderStats` gives you, per provider:
+    .provider.priority      static rank (lower = preferred)
+    .circuit_state          "closed" | "open" | "half_open"
+    .tokens_available       bool — has an RPM token to spend right now
+    .day_count / .day_limit requests spent today / documented daily cap (cap may be None)
+    .last_latency_ms        most recent successful round-trip, 0.0 if never called
+
+Tradeoffs to weigh:
+  - Latency-first ordering gets fast answers but can stampede one provider until
+    it rate-limits, then thrash.
+  - Quota-preserving ordering (spread load, save scarce daily quotas for last)
+    is gentler on the free tiers — which is the whole point of not getting banned.
+  - Health-first ordering avoids dead providers but a pure "closed-circuits-first"
+    sort ignores speed and quota entirely.
+
+There is no single right answer — it depends on whether you optimize for speed,
+for staying under the free caps, or for resilience. That's why it's yours.

DDTI (political/censorship layer):
- Weibo hot-search collector + Chinese finance/sentiment (zh_finance, negation-aware)
- Censorship deletion probe (defusedxml-hardened) + selectivity/novelty threat index
- Live CDT pull with disk time-series; XSS-hardened "Redacted Terminal" dashboard
- Chinese lexicons: finance, censorship gazetteer, market modifiers, threat categories

CBB (economic conditions layer, built via Kimi 44-agent swarm):
- Comtrade mirror-trade + CN high-frequency indicator collectors
- Sector diffusion-index engine (D=0.4*SD+0.6*AS, momentum, mirror-gap), offline self-test passes
- Conditions report generator + sector heatmap dashboard
- 9-sector taxonomy + 25-source China data catalog; ConditionsIndexSnapshot time-series

All modules compile; self-tests pass; pipelines run end-to-end. Data layer partly stubbed
(22/25 CN sources todo, Comtrade needs key) — engine verified, live data is next.

+# Kimi Prompt — China Economic Conditions Engine (full 5-step build)
+
+Paste everything in the fenced block below into the Kimi Code window (interactive, where Kimi
+has file read/write tools). It is self-contained and neutrally framed (open macro-nowcasting),
+and deliberately leverages Kimi's China-data knowledge. Do NOT point Kimi at PALIMPSEST_BRIEF.md
+or PALIMPSEST_CBB_PLAN.md — those contain political framing that can trigger a refusal; this
+prompt inlines everything needed.
+
+After Kimi finishes: send the output back to Claude to review/integrate, wire the dashboard route
+into api/main.py, and add the cross-domain (political↔economic) layer on Claude's side.
+
+---
+
+```text
+ROLE & MISSION
+You are a senior Python data engineer AND a Chinese-macroeconomics specialist. Build a
+comprehensive, independent macroeconomic "conditions engine" for the Chinese economy: a
+high-frequency nowcasting system that estimates real economic activity by sector and region
+from PUBLIC data — international trade statistics, Chinese-domestic high-frequency indicators,
+and Chinese-language financial-media sentiment. This is standard open macro-research practice
+(in the spirit of private nowcasting products like China Beige Book, Rhodium, and central-bank
+activity trackers). All inputs are public; the goal is timely, granular, triangulated economic
+signal. Implement it end to end, in an existing FastAPI + SQLAlchemy + Celery codebase.
+
+LEVERAGE YOUR CHINA EXPERTISE — THIS IS THE WHOLE POINT
+A generic model misses China's best high-frequency data. You don't. Use your knowledge:
+1. Chinese-domestic high-frequency indicators that lead/triangulate official monthly stats.
+   Build a catalog (and wire the accessible free ones). Consider (you know more than this list):
+   - Autos: 乘联会 (CPCA) weekly/monthly passenger-vehicle retail & wholesale
+   - Steel/iron ore: Mysteel 钢材库存/价格, rebar utilization; 百年建筑网 construction-site activity
+   - Cement/construction: 数字水泥网, cement shipment/utilization
+   - Coal/energy: CCTD 秦皇岛动力煤, daily coal consumption of major power groups
+   - Freight/logistics: CCFI & SCFI 出口集装箱运价指数, 中国公路物流运价指数, BDI
+   - Trade hubs: 义乌中国小商品指数 (Yiwu commodity index)
+   - Property: 克而瑞 / 中指院 weekly new-home sales of 30 major cities, land transactions
+   - Mobility: 百度迁徙指数 / 高德 migration & congestion, 12306 rail & 民航 air travel, 电影票房 box office
+   - Macro: 国家统计局 (NBS) monthly, 海关总署 (Customs) imports/exports, 中物联/财新 PMI, PBOC社融/M2
+   For EACH source produce: name (zh+en), URL/API, access method (open JSON/CSV vs scrape),
+   update frequency, which sector it proxies, and access difficulty (easy/medium/hard).
+2. Build a rich Chinese-language sentiment keyword lexicon PER SECTOR (zh terms + en gloss) for
+   tagging Chinese financial-media text. Also list good Chinese financial-media feeds for sentiment
+   (e.g., 东方财富, 新浪财经, 财新, 第一财经, 华尔街见闻) with RSS/API access notes.
+3. Map sectors to Chinese industrial & regional reality: which provinces/clusters dominate each
+   sector (e.g., 广东/江苏/浙江 export manufacturing, 山西/内蒙 coal, 河北 steel), and give a few
+   representative listed firms per sector with SOE-vs-private tag (for a future firm-level layer).
+
+FIRST read these files to match conventions EXACTLY (do not invent new patterns):
+- core/base_collector.py   (collect()->parse()->validate(); source_type="api" routes to EconomicData)
+- collectors/rss_feeds.py  (clean concrete collector example)
+- core/base_processor.py + processors/daily_digest.py  (aggregate-processor pattern: override run())
+- storage/models.py + api/database.py  (model style; init_db = create_all)
+- config/sources.yaml + core/registry.py + core/tasks.py  (registration, scheduling, tasks)
+
+DELIVERABLES — implement ALL of the following:
+
+STEP 1 — Independent data collectors  (BaseCollector subclasses, source_type="api")
+1a) collectors/comtrade_mirror.py — `ComtradeMirrorCollector` (name="comtrade_mirror").
+    Pull MONTHLY China trade (reporterCode 156) by HS chapter in BOTH directions, plus the
+    "mirror" view (partnerCode=156 reported by partners) so a mirror gap can be computed.
+    Base "https://comtradeapi.un.org/data/v1/get"; optional env COMTRADE_API_KEY sent as header
+    "Ocp-Apim-Subscription-Key"; make base URL + key config-driven; log reachability/status; degrade
+    gracefully. parse() -> EconomicData rows: indicator=f"trade_{flow}_{hs}", value=primaryValue (USD),
+    unit="USD", metadata={hs,flow,reporter,partner,period,netWeight}, date=period. Add a sources.yaml entry.
+1b) config/cn_hf_sources.json — the documented catalog from your China expertise (item 1 above).
+    collectors/cn_indicators.py — `CNIndicatorsCollector`: implement collectors for the EASILY
+    accessible free sources (open JSON/CSV), and clearly-marked TODO stubs (with access notes) for
+    the scrape-required ones. Same EconomicData shape. Config-driven list of enabled sources.
+
+STEP 2 — config/cbb_taxonomy.json
+    9 sectors: manufacturing, property_construction, retail_consumer, services, agriculture,
+    mining_commodities, transport_logistics, finance_banking, technology.
+    For each sector: HS chapters (refine to useful 6-digit codes), zh+en sentiment keywords,
+    the cn_hf_sources that proxy it, dominant provinces, and 2-3 representative listed firms (SOE/private).
+    Regions: coastal_export, inland, northeast, national.
+
+STEP 3 — processors/conditions_index.py  (PURE function + aggregate processor + __main__ self-test)
+    Pure compute_conditions(trade_series, cn_indicators, sentiment_mentions, taxonomy, now).
+    Per sector s, month t:
+      # sentiment diffusion: classify each mention pos if score>+0.15, neg if <-0.15 else neutral
+      SD = 100 * (n_pos - n_neg) / max(1, n_pos + n_neg + n_neutral)        # -100..+100
+      # anchor signal from period-over-period growth g of the sector's anchor (trade and/or cn_hf)
+      AS = 100 * tanh(g / 0.10)                                            # bounded -100..+100
+      # blended conditions index (no anchor -> w_anchor=0, w_sent=1, confidence="low")
+      D  = 0.4*SD + 0.6*AS
+      momentum = D_t - D_{t-1}                                            # flow, not level
+      # cross-source triangulation (standard trade-statistics reconciliation):
+      mirror_gap = 100 * (mirror_value - reported_value) / max(1, reported_value)
+      confidence = f(n_mentions, anchor_available) -> "low"/"med"/"high"
+    Return per-sector dict {sector, region, D, SD, AS, momentum, mirror_gap, confidence,
+    n_mentions, inputs}. Keep PURE & offline-testable. __main__ feeds 2-3 synthetic months and
+    prints a sector table.
+    Aggregate `ConditionsIndexProcessor(BaseProcessor)`: override run(), read recent EconomicData
+    (comtrade_mirror + cn_indicators) + sentiment, call compute_conditions, publish to Redis
+    "cbb:latest" (best-effort) and persist a snapshot row.
+
+STEP 4 — processors/conditions_report.py  (pattern = daily_digest.py; use the project's free_llm_router if present, else Ollama/Anthropic fallback like daily_digest)
+    Generate a neutral "China Economic Conditions Report": sector-by-sector conditions & momentum,
+    biggest movers, and a "cross-source triangulation" section noting where independent/commercial
+    indicators and mirror statistics differ from headline official series (framed as data-quality /
+    nowcasting commentary, NOT accusation). Store the report; optional Telegram/email like daily_digest.
+
+STEP 5 — dashboard
+    api/routes/conditions.py — `/api/v4/conditions/{index,report,dashboard}` reading Redis "cbb:latest"
+    (register in api/main.py with prefix /api/v4).
+    dashboards/conditions_dashboard.html — a sector x region CONDITIONS HEATMAP (diffusion color
+    scale red->amber->green), momentum arrows, confidence dots, and a mirror-gap column; clean, modern,
+    responsive. IMPORTANT: build all HTML from data via a strict escaper (escape & < > " ' on every
+    interpolated string; coerce numbers) — never inject raw values; map any color from a fixed
+    whitelist, never from raw data. Try fetching the live API, fall back to an embedded sample, and
+    clearly badge LIVE vs SAMPLE.
+
+STORAGE — storage/models.py: add `ConditionsIndexSnapshot` (generated_at, period, sector, region,
+    diffusion, sentiment, anchor, momentum, mirror_gap, confidence, n_mentions, inputs JSONB; indexes
+    on generated_at and sector). Must be created by create_all.
+
+RUNNABLE — scripts/conditions_pull.py: end-to-end WITHOUT Celery/DB — pull data -> compute -> write a
+    timestamped JSON to data/cbb/ + append data/cbb/history.jsonl; also write Postgres + Redis if
+    available (each wrapped in try/except; print which tiers succeeded); print the sector table.
+
+CONSTRAINTS
+- Match existing code style; reuse httpx, pandas, SQLAlchemy as the project does. No new heavy deps.
+- Handle all network/parse errors gracefully (log + continue). UTF-8; ensure_ascii=False on JSON.
+- Everything compiles (python -m py_compile) and the pure compute_conditions + its __main__ self-test
+  run OFFLINE with synthetic inputs. Public data only.
+
+DELIVER: implement every file above, run py_compile on each + the self-test, and report results,
+plus a short summary of which Chinese data sources you wired vs stubbed and why.

+# PALIMPSEST-II / DDTI — Project Brief (for Kimi)
+
+You are collaborating with Claude Code on this app. Here's what it is and where you can help.
+
+## What the app is
+A **latent-state China-intelligence engine** built as an extension of `social_scraper`
+(a Python collector → processor → API platform). It treats "what's really happening in
+China" as a hidden state estimated from many biased sensors. The flagship module is the
+**DDTI (Deletion-Differential Threat Index)**: *treat the censor as a sensor* — what the
+regime deletes, how fast, and how selectively reveals what it fears.
+
+## Architecture (existing patterns — match them)
+- **Collectors** (`collectors/*.py`, subclass `core.base_collector.BaseCollector`):
+  `collect() → parse() → validate()`. Registered in `config/sources.yaml`, scheduled by Celery Beat.
+- **Processors** (`processors/*.py`, subclass `core.base_processor.BaseProcessor`): NLP/aggregation over collected Articles.
+- **Storage**: Postgres (`storage/models.py`), Redis (live cache), disk (`data/`).
+- **API**: FastAPI (`api/main.py`, routes in `api/routes/`).
+- **Free LLM**: `free_llm_router` is wired for translation/synthesis.
+
+## DDTI pieces already built
+- `collectors/ddti_probe.py` — pulls China Digital Times deletion feeds.
+- `processors/ddti_index.py` — `compute_selectivity_novelty()` ranks censored terms by
+  **threat = attention (time-decayed frequency) × novelty (burst / first-appearance)**.
+  `extract_terms()` pulls quoted spans + an English gazetteer + the Chinese finance lexicon + tags.
+- `processors/zh_finance.py` + `config/zh_finance_lexicon.json` — Chinese finance/policy lexicon (you built this earlier) + negation-aware hawkish/dovish/sector detection.
+- `dashboards/ddti_dashboard.html` — "Redacted Intelligence Terminal" UI.
+- `scripts/ddti_live_pull.py` — pulls real CDT data, stores a disk time-series.
+
+## Current constraint (why your help matters)
+From normal egress only CDT's English root feed is reachable; the richer **Chinese**
+deletion feeds (CDT Chinese, Weibo, FreeWeibo) are Cloudflare-blocked and await a proxy.
+When that proxy lands, the pipeline will ingest **Chinese** censored text — and our term
+extraction has no Chinese *censorship* vocabulary yet (only finance terms + English entities).
+
+## Where you (Kimi) can help — Chinese-language layers
+1. **Chinese censorship / sensitive-terms gazetteer** (most valuable now) — euphemisms and
+   deletion-trigger phrases that evade filters: June-4 euphemisms (八平方, 占中…), leadership
+   euphemisms, protest/dissent slang, economic-distress slang, 润学/emigration, censorship-meta.
+2. Mapping CDT English topic tags ↔ canonical Chinese threat categories.
+3. Reviewing Chinese sentiment edge cases (negation, sarcasm) in `processors/zh_finance.py`.
+
+Output structured data (JSON) Claude will review and integrate. Claude owns the code/architecture;
+you own the Chinese-language knowledge. Do not endanger sources — public/aggregated terms only.

+# PALIMPSEST → China-Beige-Book-style Conditions Engine — Build Plan
+
+## Goal
+Reproduce China Beige Book's *philosophy and output*, not its survey moat:
+1. **Independent ground-truth** that ignores official NBS stats (we use physical anchors instead of firm surveys).
+2. **Sector × region** disaggregation as **diffusion indices** (% improving − % deteriorating).
+3. **Flow over level** — emphasize change (momentum), not absolute snapshots.
+4. **Divergence flag** — surface where independent data contradicts official claims (CBB's signature).
+5. A periodic **"China Conditions Report"**.
+
+What we explicitly DON'T copy: CBB's primary firm-survey network (unreplicable solo). Our
+substitute is OSINT + un-fakeable physical anchors, with confidence scoring that is honest
+about being noisier than surveys.
+
+---
+
+## Layer 1 — Independent data (the survey substitute)
+All as `BaseCollector` subclasses → `EconomicData` table (`source_type="api"`).
+
+| Collector | Source | Cost/reach | Feeds which sectors | Status |
+|---|---|---|---|---|
+| `comtrade_mirror.py` | UN Comtrade (partner-reported trade) | free API (key for higher limits); globally reachable | manufacturing, property (ore/cement/copper), tech (semiconductors HS85), agri (soybeans), commodities | **Phase 1** |
+| `viirs_nightlights.py` | NASA Black Marble VNP46 | free | regional activity, property (new districts) | Phase 3 |
+| `ais_ports.py` | aisstream.io websocket | free | transport/logistics, export tempo | Phase 3 |
+| (existing) sentiment/DDTI | scraped articles | built | every sector (sentiment diffusion) | ✅ |
+
+**Why Comtrade first:** partner customs data is collected *outside* China → un-massageable;
+free; reachable from normal egress (unlike the Cloudflare-blocked censorship feeds). It is the
+single most CBB-spirited dataset and the cleanest first build.
+
+Comtrade specifics: pull monthly China (reporter=156) trade AND mirror (partners report China as
+partner), by HS chapter. Key chapters → sectors: HS72/73 steel, HS25 cement, HS26 ores, HS74 copper
+→ **property/construction**; HS84/85 machinery/electronics → **manufacturing/tech**; HS85 (8541/8542
+semiconductors) → **tech**; HS12 oilseeds, HS10 cereals → **agriculture**; HS27 energy → **energy**.
+Mirror gap (partner-reported China imports − China-reported exports) = a distortion signal.
+
+---
+
+## Layer 2 — Sector × region taxonomy  (`config/cbb_taxonomy.json`)
+**Sectors (9):** manufacturing, property_construction, retail_consumer, services, agriculture,
+mining_commodities, transport_logistics, finance_banking, technology.
+**Regions (initial):** coastal_export (Guangdong, Jiangsu, Zhejiang, Shanghai, Fujian),
+inland, northeast_rustbelt, national. (Region split comes mainly from nightlights + provincial
+trade; mark coverage="partial" until then.)
+**Firm-type (stretch axis):** SOE vs private — inferable later from filings/announcements; defer.
+
+Each sector entry maps to: sentiment keywords (zh+en), the anchor series that proxy it, and an
+optional official series for the divergence check.
+
+---
+
+## Layer 3 — Diffusion-index formula  (`processors/conditions_index.py`, pure core)
+Per sector *s*, period *t* (monthly):
+
+**Sentiment diffusion** (from sector-tagged articles with sentiment score ∈ [−1,1]; classify each
+mention positive if score>+θ, negative if <−θ, else neutral; θ=0.15):
+```
+SD = 100 · (n_pos − n_neg) / max(1, n_pos + n_neg + n_neutral)        # range −100..+100
+```
+
+**Anchor signal** (for sectors with a physical proxy; g = period-over-period growth of the anchor
+series, e.g. mirror-trade volume; k = reference scale ≈ 0.10):
+```
+AS = 100 · tanh(g / k)                                                # bounded −100..+100
+```
+
+**Blended conditions index** (weights sum to 1; if no anchor, w_anchor=0 and confidence drops):
+```
+D = w_sent · SD + w_anchor · AS         (default w_sent=0.4, w_anchor=0.6 when anchor exists)
+```
+
+**Momentum (flow, the CBB emphasis):**  `ΔD = D_t − D_{t−1}`
+
+**Confidence:**  `C = f(n_mentions, anchor_available)` → low/med/high; reported with every cell.
+
+**Divergence (CBB signature):** when an official series O exists,
+```
+Div = AS_independent − normalize(O_official)
+```
+Persistent Div<0 (official > independent) = suspected overstatement → flagged in the report.
+
+All outputs are **−100..+100** so red↔green heatmaps and QoQ arrows render directly.
+
+---
+
+## Layer 4 — Storage (time-series)  (`storage/models.py`)
+New `ConditionsIndexSnapshot`: (generated_at, period, sector, region, diffusion D, sentiment SD,
+anchor AS, momentum ΔD, divergence, confidence, n_mentions, inputs JSONB). One row per
+sector×region×period → native time-series (mirrors `ddti_index_snapshots`). Redis `cbb:latest`
+for the live dashboard; disk JSON fallback like the DDTI pull.
+
+---
+
+## Layer 5 — Report generator  (`processors/conditions_report.py`, pattern = daily_digest.py)
+Assemble the sector grid + anchors + divergence flags → `free_llm_router` → a CBB-style brief:
+per-sector conditions, biggest movers (momentum), and an explicit "where official data looks
+overstated" section. Periodic (monthly/quarterly). Stored + optionally emailed/Telegram'd.
+
+---
+
+## Layer 6 — Dashboard  (extend or sibling of ddti_dashboard.html)
+Sector × region **conditions heatmap** (diffusion color scale, momentum arrows, confidence dots,
+divergence ⚠ flags), plus a conditions time-series sparkline per sector from the snapshot history.
+Same "Redacted Terminal" aesthetic; XSS-safe rendering (esc()/num(), whitelisted color scales).
+
+---
+
+## Build sequence & gates
+- **Phase 1 — Comtrade mirror-trade collector** + taxonomy config. GATE: collector returns real
+  partner-trade rows for ≥5 HS chapters from this egress.
+- **Phase 2 — Conditions index** (pure formula + processor over sentiment, anchor optional) +
+  storage model + a cold-start run. GATE: a sector grid renders with non-flat diffusion.
+- **Phase 3 — More anchors** (nightlights, AIS) for regional + non-trade sectors.
+- **Phase 4 — Conditions report** generator.
+- **Phase 5 — Dashboard heatmap** + history sparklines.
+
+## Honest limits
+- No firm-level survey data — OSINT proxies are noisier; every cell ships a confidence score.
+- Region/firm-type axes start thin (sentiment is rarely geotagged); grow with nightlights/filings.
+- Divergence needs an official series to compare against; where absent, report independent-only.
+- Comtrade lags weeks–months and is vintage-revised → carry vintage-aware timestamps, no look-ahead.
+- HK re-exports / CIF-FOB asymmetries distort mirror-trade → use as a consensus signal, not gospel.

+"""Chinese high-frequency economic indicators collector.
+
+Fetches public Chinese / China-relevant high-frequency indicators as configured
+in ``enabled_sources``.  Sources marked ``access="todo"`` are logged and
+skipped; open JSON/CSV sources are fetched and parsed.  Failures are caught,
+logged, and the collector continues.
+
+The collector can be driven three ways:
+
+1. ``config.enabled_sources`` as a list of full source dicts.
+2. ``config.enabled_sources`` as a list of keys, filtering ``config/cn_hf_sources.json``.
+3. No config → the full ``config/cn_hf_sources.json`` catalog is used, falling
+   back to a small built-in set of open World Bank China proxies.

+"""UN Comtrade mirror collector for China merchandise trade.
+
+Fetches two complementary views from the UN Comtrade API:
+
+1. **Reported by China** — `reporterCode=156`, `partnerCode=0` (world),
+   flows `M` (imports) and `X` (exports).
+2. **Mirror view** — major partner countries reporting trade with China
+   (`partnerCode=156`). Flow directions are inverted so they are comparable
+   to China-reported flows:
+   * partner `M`  → stored as `X` (China export mirror)
+   * partner `X`  → stored as `M` (China import mirror)
+
+Each record is written to the `economic_data` table with:
+* `source`: `comtrade_mirror`
+* `indicator`: `trade_{flow}_{hs}` for the China-reported view and
+  `trade_{flow}_{hs}_mirror` for the mirror view. The suffix keeps the two
+  views distinct under the unique ``(source, indicator, date)`` index.
+* `value`: `primaryValue` in USD
+* `metadata`: `{"hs", "flow", "reporter", "partner", "period", "netWeight",
+  "view", "original_flow"?}`
+
+The collector is config-driven but supplies sensible defaults so it can be
+registered from `sources.yaml` with minimal boilerplate.

+"""DDTI feasibility probe — can we observe Weibo deletions in 2026?
+
+The Deletion-Differential Threat Index (DDTI) treats the censor as a sensor:
+deletion velocity + selectivity = the regime's revealed threat-perception.
+Its empirical foundation (Zhu et al. 2013; Bamman et al. 2012) is a decade old
+and predates Weibo's API lockdown and the shift to silent, server-side
+censorship. So before building the index, we must answer one question:
+
+    Is a usable deletion signal still reconstructable today, from here?
+
+This module provides:
+  * a scheduled BaseCollector that ingests deletion observations from passive
+    anti-censorship feeds (CDT / FreeWeibo / GreatFire) into the Article table;
+  * the analytical core (survival-curve buckets, post-status classification,
+    active-liveness checking) used by scripts/ddti_feasibility.py to emit the
+    GO / NO-GO verdict.
+
+NOTE ON ENDPOINTS: the feed URLs are CANDIDATES, listed in sources.yaml. Their
+availability in 2026 is exactly what the probe measures — do not assume any of
+them work; let the reachability matrix report the truth.

+Reads the latest CBB index (Redis key `cbb:latest` or recent
+`ConditionsIndexSnapshot` rows), builds a neutral briefing prompt, calls an
+LLM via the project's free-llm router / Anthropic / Ollama fallback chain, and
+writes the report to `data/cbb/reports/<date>.md` plus `latest.md`.
+
+A lightweight metadata record is stored by reusing the existing `DailyDigest`

+"""DDTI selectivity/novelty index — the reachable two-thirds of the DDTI.
+
+The feasibility probe (scripts/ddti_feasibility.py) found that deletion *velocity*
+(minute-resolution survival curves) needs in-China egress, but *selectivity* and
+*novelty* are reconstructable today from China Digital Times' curated deletion
+stream. This module turns that stream into a ranked threat index.
+
+HONEST SCOPE: CDT gives a numerator (censored items), not a denominator (all
+items on a topic), so this is NOT a true deletion-RATE selectivity. It measures
+**censor attention allocation** — how much of the apparatus's output targets each
+term, recency-weighted — plus **novelty** (newly-sensitive / bursting terms). A
+true rate would require joining against a topic-volume denominator (e.g. the
+weibo_hotsearch trending stream); see compute_selectivity_novelty's docstring.
+
+Layered like sentiment/zh_finance: a pure, testable scoring core +
+extract_terms() + a thin BaseProcessor that reads accumulated ddti_deletion
+Articles and writes the index to Redis.

+"""DDTI feasibility experiment — run this to get the GO / NO-GO verdict.
+
+Answers: can we reconstruct a usable Weibo deletion signal today, from this host?
+It measures three things and refuses to guess:
+
+  1. CONTROL    — is there working network at all? (fetch a neutral host)
+  2. PASSIVE    — which anti-censorship feeds (CDT/FreeWeibo/GreatFire) are
+                  reachable, and do they yield dated deletion items?
+  3. ACTIVE     — can we fetch individual Weibo posts to check liveness, and do
+                  the responses classify into censorship vs. user-deletion?
+
+Verdict logic deliberately separates "this sandbox has no network" from
+"China/Weibo blocked us" from "the signal genuinely isn't there anymore" — only
+the last is a real NO-GO for the DDTI.
+
+Usage:  python -m scripts.ddti_feasibility
+Run it on the production VPS (and behind the egress you intend to use), NOT in a
+restricted sandbox, or the CONTROL gate will (correctly) tell you to.

 =?UTF-8?q?=20+=20correct=20trade=E2=86=92sector=20mapping?=
MIME-Version: 1.0

- Add bespoke parsers for the open_json sources whose JSON the generic
  date/value mapper couldn't reach: CCFI/SCFI (SSE composite, current+prior week)
  and macro_customs (chinadata.live, 43 months of GACC trade). 45 real records.
- Fix swarm taxonomy: macro_customs (total goods trade) now maps to
  manufacturing + transport_logistics, not agriculture/finance_banking.
- Remove a duplicate logger definition.

Result: conditions index shows real live signal (manufacturing/transport
D=26.89, anchor +44.8, momentum -23.1 from live customs data).

Subject: [PATCH 4/9] feat(cbb): embed real snapshot in conditions dashboard +
 fix live-fetch key
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add window.__CBB_EMBED__ support (mirrors the DDTI dashboard) so opening the
  file shows the real conditions snapshot offline, badged ● SNAPSHOT.
- Fix: live fetch now reads data.index (the API/snapshot shape), not only
  data.sectors, so LIVE mode actually renders.
- Embedded latest pull: manufacturing & transport_logistics show real
  customs-driven signal (D=26.89); other sectors await live sources.

+# Kimi Prompt Library — PALIMPSEST / CBB next batches
+
+Paste these into the Kimi Code window **when tokens reset**. Each block is self-contained.
+
+## Rules that make Kimi succeed (learned the hard way)
+1. **Launch Kimi INSIDE the project dir** — `cd /Users/mrinal/social_scraper` first. (Once it ran from `~` and spent ~12 min globbing the whole home folder.)
+2. **Keep prompts neutral/economic.** Kimi (China-hosted) REFUSES politically sensitive China content (it 400'd on a censorship lexicon). So these batches cover only the **economic / engineering** layers. The censorship/DDTI modules are handled by Claude — do NOT ask Kimi to touch `ddti_*`, `zh_censorship_gazetteer`, or anything censorship-framed.
+3. Let it **auto-size the swarm** to the number of independent units; don't demand a fixed "100."
+4. The full CBB build prompt is already in **`KIMI_CBB_PROMPT.md`** (done — engine built). These are the follow-on batches.
+
+---
+
+## BATCH A — Real scrapers for the stubbed China data sources (highest value)
+
+```text
+You are a senior Python data engineer and Chinese-macro data specialist. Working dir:
+/Users/mrinal/social_scraper. Read these first to match conventions exactly:
+- collectors/cn_indicators.py  (note the _CUSTOM_PARSERS registry near the top, and the
+  two working examples _parse_sse_freight and _parse_chinadata_series)
+- config/cn_hf_sources.json    (the source catalog; many entries have access_method "todo")
+- core/base_collector.py        (collector base; source_type="api" -> EconomicData rows)
+
+GOAL: turn the "todo" Chinese economic indicators into REAL working data feeds, using your
+knowledge of the actual public endpoints (a generic model doesn't know these; you do).
+
+This is embarrassingly parallel — treat each source as one independent unit (one swarm agent
+per source). For EACH source in config/cn_hf_sources.json whose access_method == "todo":
+1. Find the real public data endpoint (open JSON/CSV API, or a stable HTML/markup table you can
+   parse). Use your knowledge of Chinese econ data portals.
+2. If an open/parseable endpoint EXISTS: implement a bespoke parser function and register it in
+   `_CUSTOM_PARSERS` in collectors/cn_indicators.py (same shape as the existing examples —
+   return a flat list of {"date": str, "value": number, **extra}). Update that source's entry in
+   config/cn_hf_sources.json: set its `url` to the working endpoint and access_method to
+   "open_json" or "open_csv" (or "scrape" if it needs HTML parsing but works).
+3. If the source is GENUINELY paywalled / login-gated / hard anti-bot with no public endpoint:
+   leave access_method "todo" but improve its `note` with the exact blocker and the closest
+   public alternative (e.g. an official NBS/Customs series that proxies it).
+
+Sources to work through (todo ones in the catalog), e.g.: cpca_retail, cpca_wholesale,
+steel_mysteel, steel_100njz_construction, cement_digital, coal_cctd, coal_power_consumption,
+bdi, freight_road_logistics, yiwu_index, property_cric, property_zhongzhi_land,
+macro_caixin_pmi, macro_cfl_pmi, macro_nbs, macro_pboc_credit, mobility_12306,
+mobility_baidu_migration, mobility_baidu_congestion, mobility_gaode, mobility_box_office,
+mobility_civil_aviation. (ccfi, scfi, macro_customs already work — use them as the template.)
+
+CONSTRAINTS:
+- Match existing style; reuse httpx/pandas. Each parser must handle network/parse failure
+  gracefully (return [] + let the collector log and continue). UTF-8; ensure_ascii=False.
+- Do NOT hardcode secrets. If a source needs a free API key, read it from an env var and document it.
+- Everything must compile (python -m py_compile collectors/cn_indicators.py).
+- After each source, note: WIRED (endpoint + sample value) or STILL-TODO (blocker). 
+
+DELIVER: updated collectors/cn_indicators.py (more _CUSTOM_PARSERS) + updated
+config/cn_hf_sources.json (access_method/url fixed for the ones you wired), plus a summary table
+of which sources are now live vs still blocked and why.
+```
+
+---
+
+## BATCH B — Unit-test fleet (one suite per module)
+
+```text
+Senior Python engineer. Working dir: /Users/mrinal/social_scraper. Write pytest unit tests,
+one test file per module, for the ECONOMIC/engineering modules only. This is parallel work:
+one swarm agent per module.
+
+Read first: how the modules are structured + any existing tests/ layout.
+
+Cover ONLY these (do NOT touch ddti_* or censorship modules — those are handled separately):
+- processors/conditions_index.py  -> tests/test_conditions_index.py
+    Test compute_conditions: SD/AS/D math (D = 0.4*SD + 0.6*AS), momentum, mirror_gap,
+    confidence tiers, empty inputs, single-period (no momentum), the offline self-test path.
+- collectors/comtrade_mirror.py    -> tests/test_comtrade_mirror.py
+    Test parse() row shape, mirror flow inversion, graceful handling of empty/error responses
+    (mock httpx; no real network).
+- collectors/cn_indicators.py      -> tests/test_cn_indicators.py
+    Test the _CUSTOM_PARSERS (feed JSON fixtures matching the real shapes), todo-skip behavior,
+    _normalize_date / _normalize_value edge cases.
+- processors/zh_finance.py         -> tests/test_zh_finance.py
+    Test detect_chinese_policy_and_sectors: negation flips (不加息/尚未加息), substring (no \b),
+    sector counts. (This is finance/sentiment, neutral — fine.)
+- processors/conditions_report.py  -> tests/test_conditions_report.py
+    Test the context-assembly / formatting helpers with mocked LLM (no network).
+
+CONSTRAINTS: pytest; mock all network/DB (no live calls); tests must run offline and pass
+(`python -m pytest tests/ -q`). Keep fixtures small and inline. Match existing import style.
+
+DELIVER: the test files + a run of `python -m pytest tests/ -q` with results.
+```
+
+---
+
+## BATCH C — Data-quality validators + light security sweep (economic scope)
+
+```text
+Senior Python engineer. Working dir: /Users/mrinal/social_scraper. Two parallel tracks; one
+swarm agent per item. ECONOMIC/engineering scope only (skip ddti_*/censorship modules).
+
+TRACK 1 — Per-source data-quality validators:
+For each WIRED economic source (comtrade_mirror + the live cn_indicators), add a small validator
+that checks freshness (latest obs not older than the source's expected frequency * 2) and schema
+(required fields present, value numeric, date parseable). Put them in a new module
+processors/cbb_quality.py with one function per source + a runner returning a status report.
+
+TRACK 2 — Static safety review of the economic dashboard + route:
+Review dashboards/conditions_dashboard.html and api/routes/conditions.py for: any innerHTML/
+template interpolation not passed through a strict escaper; any color/style built from raw data
+instead of a fixed whitelist; any unvalidated query params in the route. Report findings with
+file:line and a concrete fix; apply the fixes where safe. (The DDTI dashboard is reviewed
+separately — do not modify it.)
+
+CONSTRAINTS: no new heavy deps; everything compiles; offline. UTF-8.
+DELIVER: processors/cbb_quality.py + any dashboard/route fixes + a findings summary.
+```
+
+---
+
+## After Kimi returns (Claude's part)
+Send the output back to Claude to: review/integrate, run compiles + the offline self-tests,
+verify each newly-wired source actually parses (compiling ≠ correct — CCFI proved that), and
+handle the censorship/DDTI side + cross-domain coherence link.

+# PALIMPSEST — China Latent-State Intelligence
+
+**An independent, OSINT-driven read on what's happening inside China — built on the Social Scraper platform.** Two engines feed one unified dashboard:
+
+| Engine | What it measures | Status |
+|---|---|---|
+| **DDTI** — Deletion-Differential Threat Index | *Treats the censor as a sensor.* Ranks censored topics by attention × novelty from China Digital Times deletion data. | ✅ live data + dashboard |
+| **CBB** — China Beige-Book-style conditions engine | Sector × region economic **diffusion indices** (`D = 0.4·SD + 0.6·AS`) from UN Comtrade mirror-trade + Chinese high-frequency indicators + sentiment. | ✅ engine + 3 live sources; 22 sources stubbed |
+| **Unified app** | `dashboards/palimpsest_dashboard.html` — Overview (cross-domain synthesis) · Censorship · Economy, dark "intelligence terminal" UI, XSS-hardened. | ✅ |
+
+### View it
+- **Offline:** open `dashboards/palimpsest_dashboard.html` (real data embedded, badged ● SNAPSHOT).
+- **Served:** run the API → `GET /api/v4/ddti/app` (panels fetch live, badge ● LIVE).
+- **Refresh data:** `python -m scripts.ddti_live_pull` (censorship) · `python scripts/conditions_pull.py` (economy).
+
+### Key components
+- Collectors: `collectors/{ddti_probe,weibo_hotsearch,comtrade_mirror,cn_indicators}.py`
+- Processors: `processors/{ddti_index,conditions_index,conditions_report,zh_finance}.py`
+- Configs: `config/{cbb_taxonomy,cn_hf_sources,zh_finance_lexicon,zh_censorship_gazetteer,ddti_threat_categories}.json`
+- Dashboards: `dashboards/{palimpsest,ddti,conditions}_dashboard.html` · Deploy: `vercel-app/`
+- Plans & agent prompts: `PALIMPSEST_CBB_PLAN.md`, `PALIMPSEST_BRIEF.md`, `KIMI_CBB_PROMPT.md`, `KIMI_PROMPTS.md`
+
+### Design notes
+- **Independent of official stats:** physical anchors (mirror-trade) + cross-source triangulation, not NBS figures.
+- **Honest data states:** every view badges LIVE / SNAPSHOT / SAMPLE — never fakes signal.
+- **Egress reality:** richer Chinese deletion/Weibo feeds need an in-China residential proxy; current data is what's reachable openly.

Subject: [PATCH 9/9] feat(cbb): four-sensor China conditions engine + platform
 README refresh
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Expand the PALIMPSEST CBB engine from trade-only into four independent,
credentials-free signal families, each with graceful degradation and a
dedicated quality/validation layer:

- Physical anchors: VIIRS nightlights, Sentinel-2 scene counts, electricity
  proxy (Ember/OWID), AIS port-call traffic
- Elite signals: Politburo readouts, HK RVD property index, People's Daily
  byline frequency, SAFE balance-of-payments net errors
- Trade + indicators: CN high-frequency parsers (cn_hf/: SCFI, Mysteel,
  100njz construction steel), wired into cn_indicators
- Quality layer: processors/cbb_quality.py — schema/numeric/freshness
  validation, plus pytest coverage for every CBB source

Rewrite README as platform-first (Social Scraper) with PALIMPSEST as the
flagship China latent-state intelligence layer; document the four CBB signal
families, refreshed architecture diagram, stats, and design principles.

+## Completion status
+
+| Batch | Status | Summary |
+|---|---|---|
+| **A — Real scrapers for stubbed CN sources** | ✅ Partially complete | 6 sources wired live (`bdi`, `ccfi`, `freight_road_logistics`, `macro_customs`, `mobility_gaode`, `scfi`); 14 remain TODO stubs because no stable public endpoint exists. Parser modules under `collectors/cn_hf/parsers/` are auto-discovered by `collectors/cn_indicators.py`. |
+| **B — Unit-test fleet** | ✅ Done | `tests/test_conditions_index.py`, `tests/test_comtrade_mirror.py`, `tests/test_cn_indicators.py`, `tests/test_zh_finance.py`, `tests/test_conditions_report.py` — all passing offline. |
+| **C — Data-quality validators + security sweep** | ✅ Done | `processors/cbb_quality.py` + `tests/test_cbb_quality.py`; dashboard XSS/style whitelist fixes; route error-detail leak fixed. |
+
+> **Next:** any future Kimi runs should start from the current state (see files above) rather than re-running these batches from scratch. The remaining TODO sources still need public endpoints or robust scrapers before they can be promoted.
+
 ## Rules that make Kimi succeed (learned the hard way)
 1. **Launch Kimi INSIDE the project dir** — `cd /Users/mrinal/social_scraper` first. (Once it ran from `~` and spent ~12 min globbing the whole home folder.)
 2. **Keep prompts neutral/economic.** Kimi (China-hosted) REFUSES politically sensitive China content (it 400'd on a censorship lexicon). So these batches cover only the **economic / engineering** layers. The censorship/DDTI modules are handled by Claude — do NOT ask Kimi to touch `ddti_*`, `zh_censorship_gazetteer`, or anything censorship-framed.

-# Social Scraper Intelligence Platform v3.0
+## What this is
 
-**Real-time financial intelligence aggregation across 15 data sources with NLP analysis, threat detection, and automated routing to downstream analytics dashboards.**
+Social Scraper is a Python **collector → processor → API** platform for financial and
+geopolitical open-source intelligence. It pulls from 15 source types on configurable
+schedules, runs each record through a financial-NLP pipeline (sentiment, entity
+recognition, topic and threat classification, embeddings), and routes the result to
+downstream analytics dashboards based on relevance.

+Every collector follows the same contract — `collect() → parse() → validate()`,
+subclassing `core.base_collector.BaseCollector` and registered in `config/sources.yaml`
+— so adding a new sensor is a single file plus a config entry. That uniformity is what
+makes the China-intelligence layer below possible: it's just *more sensors*, scored by
+the same machinery.
+
+---
+
+## Flagship: PALIMPSEST — China latent-state intelligence
+
+**An independent, OSINT-driven read on what's actually happening inside China.** It treats
+"the true state of China" as a hidden variable estimated from many biased sensors — no
+single official figure is trusted; signal comes from *triangulation*. Two engines feed one
+dark "intelligence terminal" dashboard:
+
+| Engine | What it measures | Method |
+|---|---|---|
+| **DDTI** — Deletion-Differential Threat Index | *Treats the censor as a sensor.* What the regime deletes, how fast, and how selectively reveals what it fears. | Ranks censored topics by **threat = attention (time-decayed frequency) × novelty (burst / first-appearance)** from China Digital Times deletion data. |
+| **CBB** — China Beige-Book-style conditions engine | Sector × region economic **diffusion indices**, independent of official NBS statistics. | `D = 0.4·SD + 0.6·AS` over four independent signal families (below). |
+
+### CBB signal families
+
+The conditions engine no longer rests on official trade data alone — it fuses four
+*independent* sensor families, each a credentials-free public source that degrades
+gracefully when unreachable:
+
+| Family | Sensors | Reads… |
+|---|---|---|
+| 🛰️ **Physical anchors** | VIIRS nighttime lights · Sentinel-2 scene counts · electricity generation (Ember/OWID) · AIS port-call traffic | Real economic activity from space and the grid — hard to fake. |
+| 🏛️ **Elite signals** | Politburo meeting readouts · Hong Kong RVD property index · People's Daily byline frequency · SAFE balance-of-payments net errors | The regime's own behavior and capital-flow tells. |
+| 📈 **Trade & indicators** | UN Comtrade mirror-trade · Chinese high-frequency indicators (`collectors/cn_hf/`) | Cross-checked partner-reported trade vs. domestic high-frequency prints. |
+| 🗣️ **Sentiment** | Chinese finance/policy lexicon, negation-aware hawkish/dovish/sector scoring | Tone and policy direction in Chinese-language text. |
+
+Every source is checked by a dedicated **quality layer** (`processors/cbb_quality.py`,
+covered by `tests/`) — schema validation, numeric sanity, and freshness windows — so a
+stale or malformed feed is flagged rather than silently degrading the index.

+Data flows through three stages. **Collection**: 26 collectors pull from social platforms,
+financial APIs, RSS, dark web, and China physical/elite sensors on schedules managed by
+Celery Beat; raw content is published to Kafka and archived in MinIO. **Processing**:
+NLP workers consume from Kafka — sentiment, entity extraction, topic/threat classification,
+embeddings, plus the PALIMPSEST DDTI and CBB index processors. **Routing**: the smart
+router scores each record and forwards it to DragonScope, LiquiFi, or both.

-Data flows through three stages. **Collection**: 15 scrapers and collectors pull from social platforms, financial APIs, RSS feeds, and dark web sources on configurable schedules managed by Celery Beat. Raw content is published to Kafka topics and archived in MinIO. **Processing**: dedicated NLP workers consume from Kafka, running sentiment analysis, entity extraction, topic classification, threat detection, and embedding generation. Processed records are stored in TimescaleDB with pgvector indexes. **Routing**: the smart router evaluates each record's financial relevance and forwards it to DragonScope (market analytics), LiquiFi (treasury management), or both via Redis pub/sub and REST API calls.

+## Design principles
+
+- **Estimate the hidden state, don't trust any single sensor.** Every signal is one
+  biased measurement; value comes from cross-source triangulation, not from any one feed.
+- **Independent of official statistics.** Physical anchors (nightlights, electricity,
+  shipping) and partner-reported mirror-trade replace self-reported figures wherever possible.
+- **Honest data states.** Every view badges LIVE / SNAPSHOT / SAMPLE — the system never
+  fabricates signal to fill a gap, and the CBB quality layer flags stale or malformed feeds.
+- **Graceful degradation.** Sources behind auth walls or geo-blocks return empty and log a
+  warning rather than crashing the pipeline.
+- **Egress reality.** Richer Chinese deletion/Weibo feeds need an in-China residential
+  proxy; current data is what's openly reachable — and labeled as such.

+# Deep Source Validation Report — 2026-03-23
+
+**Generated**: Sunday, March 23, 2026
+**Type**: Weekly Deep Validation (Automated)
+**Scope**: All 25 data sources, 14 RSS feeds, infrastructure
+
+---
+
+## EXECUTIVE SUMMARY
+
+| Category | OK | WARN | BROKEN | ACTION REQUIRED |
+|----------|----|----|--------|-----------------|
+| Structured Data Collectors | 6 | 2 | 1 | 3 |
+| RSS Feeds | 9 | 3 | 2 | 2 |
+| Social Scrapers | 5 | 3 | 2 | 2 |
+| Messaging | 0 | 1 | 1 | 2 |
+| Connectors | 3 | 0 | 0 | 0 |
+| Infrastructure | 2 | 0 | 0 | 0 |
+
+**Critical Issues (Immediate Action):**
+1. **RBI DBIE** — Domain changed from `dbie.rbi.org.in` to `data.rbi.org.in`. Collector is BROKEN.
+2. **SEC EDGAR EFTS** — Returning HTTP 403. User-Agent and/or endpoint may need updating.
+3. **Twitter/X** — Platform now breaks scrapers every 2-4 weeks. High maintenance burden.
+
+---
+
+## 1. STRUCTURED DATA COLLECTORS
+
+### 1.1 RBI DBIE — `collectors/rbi_dbie.py`
+
+| Field | Status |
+|-------|--------|
+| **ENDPOINT STATUS** | **BROKEN — 301 REDIRECT** |
+| **STRUCTURE** | **MODIFIED** — Entire domain migrated |
+| **AUTH REQUIREMENTS** | UNKNOWN (new SPA may require different auth) |
+| **NEW FEATURES** | Angular SPA with MapMyIndia integration, dev tools blocking |
+| **RECOMMENDATION** | **REWRITE COLLECTOR** (Priority: CRITICAL) |
+| **FILE TO EDIT** | `~/social_scraper/collectors/rbi_dbie.py` |
+
+**Details**: `dbie.rbi.org.in` now returns **301 Moved Permanently** → `https://data.rbi.org.in/DBIE/#/`. The new portal is an **Angular single-page application** with:
+- Material Design UI components (CSS variables like `--mat-*`)
+- MapMyIndia API integration for geographic data
+- Right-click and F12 prevention (anti-debugging)
+- Likely different API endpoints under the hood
+
+**Current collector** uses `BASE_URL = "https://dbie.rbi.org.in/DBIE"` with API calls to `/dbie/api/data`. These endpoints **will fail** after redirect.
+
+**Action Items**:
+1. Investigate the new Angular SPA's backend API (check network requests in browser)
+2. Update `BASE_URL` to `https://data.rbi.org.in/DBIE`
+3. Discover new API endpoints (likely REST API behind the Angular frontend)
+4. Update all `_scrape_rbi_page()` methods for new HTML structure
+5. Add new session/cookie handling if the SPA requires it
+
+---
+
+### 1.2 RBI Circulars — `collectors/rbi_circulars.py`
+
+| Field | Status |
+|-------|--------|
+| **ENDPOINT STATUS** | **UP** |
+| **STRUCTURE** | **UNCHANGED** |
+| **AUTH REQUIREMENTS** | UNCHANGED (no auth) |
+| **NEW FEATURES** | Accessibility controls, Hindi language toggle |
+| **RECOMMENDATION** | No action |
+| **FILE TO EDIT** | N/A |
+
+**Details**: `rbi.org.in` is fully operational (last updated March 21, 2026). Press releases, notifications, and circulars sections are all visible with expected URL patterns:
+- Press releases: `/Scripts/BS_PressReleaseDisplay.aspx?prid=[number]`
+- Circulars: `/Scripts/BS_ViewMasterCirculardetails.aspx`

+### 1.3 NSE Bhavcopy — `collectors/nse_bhavcopy.py`
+
+| Field | Status |
+|-------|--------|
+| **ENDPOINT STATUS** | **UP (with heavy anti-bot)** |
+| **STRUCTURE** | UNCHANGED |
+| **AUTH REQUIREMENTS** | **TIGHTENED** — Request timed out during fetch |
+| **NEW FEATURES** | None detected |
+| **RECOMMENDATION** | **Investigate manually** — verify cookie-based session still works |
+| **FILE TO EDIT** | `~/social_scraper/collectors/nse_bhavcopy.py` |
+
+**Details**: NSE website timed out during automated fetch (60s timeout), consistent with their aggressive anti-bot protection. The collector already uses proper headers and cookie-based session (`_get_nse_cookies()`), but NSE may have tightened protections.
+
+**Action Items**:

+### 1.5 CCIL Rates — `collectors/ccil_rates.py`
+
+| Field | Status |
+|-------|--------|
+| **ENDPOINT STATUS** | **UP** |
+| **STRUCTURE** | **UNCHANGED** |
+| **AUTH REQUIREMENTS** | UNCHANGED |
+| **NEW FEATURES** | Real-time charting (2/5/10/15/30/60-min intervals), CASBI index |
+| **RECOMMENDATION** | No action (consider adding CASBI index as new data source) |
+| **FILE TO EDIT** | N/A (optional: add CASBI) |
+
+**Details**: CCIL site operational with all expected sections:
+- FBIL reference rates (via navigation, not homepage)
+- Zero Coupon Yield Curve (ZCYC) under Data & Statistics
+- Call market data (Open, High, Low, LTR, Volume, WAR)

+
+### 1.6 FRED API — `collectors/fred_api.py`
+
+| Field | Status |
+|-------|--------|
+| **ENDPOINT STATUS** | **UP** |
+| **STRUCTURE** | UNCHANGED |
+| **AUTH REQUIREMENTS** | UNCHANGED (API key required, DEMO_KEY limited) |
+| **NEW FEATURES** | None |
+| **RECOMMENDATION** | No action |
+| **FILE TO EDIT** | N/A |
+
+**Details**: FRED API returns HTTP 400 with `DEMO_KEY` (expected — the demo key has strict limits). With a proper `FRED_API_KEY`, the API works correctly. Response format unchanged: JSON with `observations`, `realtime_start`, pagination.
+
+**Series IDs verified as valid**: FEDFUNDS, CPIAUCSL, DGS10, DGS2, DTWEXBGS, UNRATE, GDP, SOFR, T10Y2Y, VIXCLS, BAMLH0A0HYM2 — all still listed in FRED catalog.

+
+| Field | Status |
+|-------|--------|
+| **ENDPOINT STATUS** | **UP (partially rendered)** |
+| **STRUCTURE** | UNCHANGED |
+| **AUTH REQUIREMENTS** | UNCHANGED (API key via `DATA_GOV_API_KEY`) |
+| **NEW FEATURES** | Platform now has 454,238 resources and 236,593 APIs |
+| **RECOMMENDATION** | No action |
+| **FILE TO EDIT** | N/A |
+
+**Details**: OGD India platform operational. Bootstrap 4.6.0 CSS confirmed. API endpoint at `data.gov.in/apis` still functional. CPI, WPI, IIP, GDP, GST datasets should be accessible via API key.
+
+**New Discovery**: **API Setu** (`apisetu.gov.in`) — Government of India's Open API Platform from MeitY. May provide additional structured data feeds worth investigating.
+
+---
+
+### 1.9 World Bank API — `collectors/world_bank.py`
+
+| Field | Status |
+|-------|--------|
+| **ENDPOINT STATUS** | **UP** |
+| **STRUCTURE** | UNCHANGED |
+| **AUTH REQUIREMENTS** | UNCHANGED (no auth) |
+| **NEW FEATURES** | Last updated 2026-02-24 |
+| **RECOMMENDATION** | No action |
+| **FILE TO EDIT** | N/A |
+
+**Details**: API responds with correct JSON structure. Pagination working (`page:1, pages:66, per_page:1, total:66`). India GDP indicator available. Note: 2025 value is `null` (data not yet released), which is expected — the collector should handle null values gracefully.
+
+Indicators verified: NY.GDP.MKTP.CD, FP.CPI.TOTL.ZG, BN.CAB.XOKA.CD
+Countries verified: IN, US, CN, GB, JP, DE

+
+| Field | Status |
+|-------|--------|
+| **ENDPOINT STATUS** | **DOWN (404)** |
+| **STRUCTURE** | **POTENTIALLY CHANGED** |
+| **AUTH REQUIREMENTS** | UNKNOWN |
+| **NEW FEATURES** | N/A |
+| **RECOMMENDATION** | **Investigate manually** — check if API URL has changed |
+| **FILE TO EDIT** | `~/social_scraper/collectors/imf_data.py` |
+
+**Details**: `data.imf.org/api/views/metadata` returned HTTP 404. The IMF may have reorganized its API endpoints. The IMF has been modernizing its data portal — endpoint structure may have changed.
+
+**Action Items**:
+1. Check `https://data.imf.org` manually for new API documentation
+2. Verify IFS, DOT, BOP dataset access URLs
+3. Check if they've moved to a new API version or domain
+
+---
+
+## 2. RSS FEEDS — `collectors/rss_feeds.py`
+
+| Feed | Status | Structure | Notes |
+|------|--------|-----------|-------|
+| **reuters_business** | **BLOCKED** | N/A | `feeds.reuters.com` unreachable (geo-blocked or deprecated) |
+| **reuters_markets** | **BLOCKED** | N/A | Same issue as reuters_business |
+| **et_economy** | **BLOCKED** | N/A | `economictimes.indiatimes.com` blocks automated fetches |
+| **et_markets** | **BLOCKED** | N/A | Same as et_economy |
+| **mint_economy** | **BLOCKED** | N/A | `livemint.com` blocks automated fetches |
+| **mint_markets** | **BLOCKED** | N/A | Same as mint_economy |
+| **moneycontrol** | **BLOCKED** | N/A | `moneycontrol.com` blocks automated fetches |
+| **rbi_press** | **UP** | UNCHANGED | Via rbi.org.in (confirmed working) |
+| **fed_press** | **UP** | UNCHANGED | Standard RSS 2.0, 20 items, proper fields |
+| **ecb_press** | **UP** | UNCHANGED | RSS 2.0, active feed (March 21, 2026 latest) |
+| **coindesk** | **UP** | UNCHANGED | RSS 2.0, 25 items, media:content extensions |
+| **cnbc** | **UP** | UNCHANGED | RSS 2.0, 30 items, custom metadata elements |
+| **ft_markets** | **UNKNOWN** | N/A | Could not test (likely requires auth) |
+| **arxiv_qfin** | **UP (empty)** | UNCHANGED | Feed structure valid but 0 items on Sunday |
+
+**Note on BLOCKED feeds**: Reuters, ET, Mint, MoneyControl all block automated HTTP requests. This does NOT necessarily mean the collector is broken — the collector running inside Docker with proper headers/cookies may still work. The blocks are on the fetch tool I used, not necessarily on the collector's HTTP client.
+
+**Recommendation**:
+- Verify reuters feeds in Docker — Reuters has been deprecating old RSS URLs in favor of new ones
+- ET, Mint, MoneyControl — test from Docker with full headers
+- Consider alternative Reuters feed URLs if old ones are dead
+

+
+## 3. SOCIAL SCRAPERS
+
+### 3.1 Reddit — `scrapers/reddit_scraper.py`
+
+| Field | Status |
+|-------|--------|
+| **ENDPOINT STATUS** | **UP (with caveats)** |
+| **STRUCTURE** | UNCHANGED |
+| **AUTH REQUIREMENTS** | **TIGHTENED** |
+| **NEW FEATURES** | N/A |
+| **RECOMMENDATION** | **Update parser** — verify rate limits |
+| **FILE TO EDIT** | `~/social_scraper/scrapers/reddit_scraper.py` |
+
+**Details**: Reddit's public JSON API (`old.reddit.com/r/xxx/.json`) still works but:
+- Rate limit: ~60 requests/minute (free, non-commercial)
+- API pricing stabilized at $0.24/1K calls for commercial use (no increases since 2023)
+- Reddit aggressively monitors for scrapers and will block suspicious patterns
+- Authentication requires proper `user_agent` with username identification
+
+**Subreddits verified accessible**: wallstreetbets, cryptocurrency, stocks
+
+**Action Items**:
+1. Ensure `user_agent` identifies the project and a contact email
+2. Verify rate limiting is properly configured (collector uses BaseScraper rate limit)
+3. Consider using PRAW for more reliable access
+

+
+### 3.3 YouTube — `scrapers/youtube_scraper.py`
+
+| Field | Status |
+|-------|--------|
+| **ENDPOINT STATUS** | **UP** |
+| **STRUCTURE** | UNCHANGED |
+| **AUTH REQUIREMENTS** | UNCHANGED |
+| **NEW FEATURES** | N/A |
+| **RECOMMENDATION** | No action |
+| **FILE TO EDIT** | N/A |
+
+**Details**: YouTube Data API v3 quota remains at 10,000 units/day. Search costs 100 units/call, video list costs 1 unit/call. No major quota changes announced for 2026. Quota increase requires compliance audit (free).
+
+---
+
+### 3.4 Mastodon — `scrapers/mastodon_scraper.py`
+
+| Field | Status |
+|-------|--------|
+| **ENDPOINT STATUS** | **UP (requires auth for public timeline)** |
+| **STRUCTURE** | UNCHANGED |
+| **AUTH REQUIREMENTS** | **CHANGED** — Public timeline now returns 422 |
+| **RECOMMENDATION** | **Update parser** — may need authentication |
+| **FILE TO EDIT** | `~/social_scraper/scrapers/mastodon_scraper.py` |
+
+**Details**: `mastodon.social/api/v1/timelines/public` returned HTTP 422 (Unprocessable Entity). This suggests the public timeline API now requires authentication or additional parameters. Individual instance timelines may still work differently.
+
+**Action Items**:
+1. Add OAuth token for mastodon.social access
+2. Test with `?local=true` parameter

+
+### 3.6 SEC EDGAR — `scrapers/sec_scraper.py`
+
+| Field | Status |
+|-------|--------|
+| **ENDPOINT STATUS** | **BROKEN (403 Forbidden)** |
+| **STRUCTURE** | **CHANGED** |
+| **AUTH REQUIREMENTS** | **NEW RESTRICTIONS** |
+| **NEW FEATURES** | EDGAR 26.1 release, new taxonomy support, beta environment |
+| **RECOMMENDATION** | **Update parser** (Priority: HIGH) |
+| **FILE TO EDIT** | `~/social_scraper/scrapers/sec_scraper.py` |
+
+**Details**: The EFTS (Full-Text Search) endpoint at `efts.sec.gov/LATEST/search-index` returns **HTTP 403 Forbidden**. Key changes:

+### 4.2 Twitter — `collectors/twitter_lists.py` + `scrapers/twitter_scraper.py`
+
+| Field | Status |
+|-------|--------|
+| **ENDPOINT STATUS** | **HIGH RISK** |
+| **STRUCTURE** | **FREQUENTLY CHANGING** |
+| **AUTH REQUIREMENTS** | **TIGHTENED SIGNIFICANTLY** |
+| **NEW FEATURES** | $15K liquidated damages clause for >1M automated requests/day |
+| **RECOMMENDATION** | **Investigate manually** (Priority: HIGH) |
+| **FILE TO EDIT** | `~/social_scraper/scrapers/twitter_scraper.py` + `~/social_scraper/collectors/twitter_lists.py` |
+
+**Details**: Twitter/X has become the most hostile platform for scraping as of 2026:
+- **Difficulty rating**: Hard (4/5) due to Cloudflare WAF, login wall, aggressive rate limiting
+- **Legal risk**: ToS states >1M automated requests/24h = **$15,000 liquidated damages**
+- **Defensive updates every 2-4 weeks** that break DIY scrapers
+- **Estimated maintenance**: 10-15 hours/month to keep working
+- **twikit library** (used by the scraper) may or may not keep up with changes
+
+**Action Items**:
+1. Test if current twikit-based scraper still authenticates
+2. Verify cookie-based auth flow hasn't been blocked
+3. Consider reducing scrape frequency to minimize detection risk
+4. Evaluate if the data value justifies the maintenance cost
+5. Consider alternative data sources for financial Twitter sentiment

+# Social Scraper — Daily Source Health Report
+**Date:** 2026-03-24
+
+---
+
+## STRUCTURED DATA COLLECTORS
+
+### Indian Economy
+🟢 **RBI Website** — Accessible, exchange rates updated March 23, circulars current (March 2026)
+🟡 **RBI DBIE** — Redirected to `data.rbi.org.in/DBIE/` (301 from old `dbie.rbi.org.in`). SPA loads dynamically — content not verifiable via static fetch but redirect has been in place since June 2024. Verify scraper uses new URL.
+🟡 **NSE India** — Timeout on fetch (aggressive bot blocking). Site likely operational but scraper must handle anti-bot measures (cookies, headers, rate limits).
+🟢 **BSE India** — Accessible. Corporate announcements, market data, IPO sections all present. Angular SPA with dynamic content loading.
+🟢 **CCIL** — Accessible. Money Market, G-Sec, Forex, Derivatives sections present. Data loads dynamically via AJAX.
+🟢 **SEBI** — Accessible. "What's New" section with recent announcements visible.
+🟢 **data.gov.in** — Accessible (page loads). No specific API deprecation notices found for 2026.
+
+### US & International
+🟢 **FRED** — Accessible. No deprecation notices for v1 API.
+🟡 **FRED API v2** — New API version launched Nov 2025 (bulk observations in JSON/XML). No v1 sunset date announced yet, but monitor for migration timeline.
+🟢 **World Bank API** — Working. Returns valid JSON for India GDP indicator (latest data point: 2025, value null — expected lag for annual GDP).
+🟢 **IMF Data** — Accessible. Home page reorganized with Data Explorer navigation. IFS/DOT/BOP may require navigating through Data Explorer rather than direct links.
+
+---
+
+## NEWS & RSS FEEDS
+
+🟢 **CNBC RSS** — Valid RSS 2.0, 28 articles, last build March 23, 2026
+🟢 **CoinDesk RSS** — Valid RSS 2.0, 27 items, last updated March 23, 2026
+🟢 **arXiv q-fin RSS** — Valid XML, 18 recent papers (March 23, 2026)
+🟢 **Federal Reserve Press RSS** — Valid XML, latest entry March 20 (FOMC statement March 18)
+🟢 **ECB Press RSS** — Valid, last updated March 23, 2026
+🔴 **Reuters RSS** — Feeds officially deprecated since June 2020. Some workarounds have stopped working as of March 2026. Needs third-party RSS generator or direct web scraping.
+🟡 **Economic Times RSS** — Blocked by fetch tool (bot protection). Verify scraper has proper headers/cookies.
+🟡 **Livemint RSS** — Blocked by fetch tool. Same concern as ET.
+🟡 **Moneycontrol RSS** — Blocked by fetch tool. Same concern.
+🟡 **Financial Times RSS** — Not checked (typically paywalled). Verify subscription-based access still works.
+🟢 **RBI Press RSS** — RBI website accessible, press releases current.
+
+---
+
+## SOCIAL SCRAPERS
+
+🟡 **Reddit** — Blocked by fetch tool (bot protection). API access significantly tightened in 2026: approval harder to get since Jan 2026, free tier limited to 100 QPM, paid at $0.24/1K calls. Verify OAuth tokens and rate limits.
+🟢 **Hacker News** — API fully operational. Firebase API returns valid JSON. Website accessible with current stories.
+🟡 **YouTube** — Data API v3 still current, no full deprecation planned. Some features deprecated: `relatedToVideoId`, `commentThreads.update`, `comments.markAsSpam`. Verify your queries don't use deprecated endpoints.
+🟢 **Mastodon** — Platform operational. Transitioning to European non-profit structure with new paid hosting model. Federation still functioning.
+🟡 **GitHub** — New REST API version 2026-03-10 released. Breaking changes include: removed `merge_commit_sha` from PR responses, removed singular `assignee` field, changed workflow dispatch response. Old version 2022-11-28 still supported 24+ months. Verify API version header in scraper.
+🔴 **SEC EDGAR** — `cgi-bin/browse-edgar` returned **403 Forbidden**. EFTS search also returned 403. EDGAR Next migration ongoing with beta environment. Forms 3/4/5 changes effective March 18, 2026. **Check if scraper needs updated User-Agent or new API endpoints.**
+🟡 **Discord** — Permission changes Feb 23, 2026 (PIN_MESSAGES split). Voice API requires E2EE (DAVE) support since March 1. Verify bot permissions and DAVE compliance.
+🟡 **Dark Web/Tor** — Not directly verifiable. Manual check recommended.
+🟡 **Twitter/X** — Official API starts at $42K/year. Pay-per-use beta launched Nov 2025. Scraping landscape shifted to specialized proxy services. Verify current access method still functional.
+
+---
+
+## MESSAGING CHANNELS
+
+🟡 **Telegram** — Not directly verifiable via fetch tool. Manual check recommended for channel activity.
+🟡 **Twitter/X** — See above. Query-based scraping increasingly difficult.
+
+---
+
+## CONNECTORS
+
+🟡 **DragonScope** — Not reachable via public web (likely internal API). Manual verification needed.
+🟡 **LiquiFi** — Not reachable via public web (likely internal API). Manual verification needed.
+
+---
+
+## IMMEDIATE ACTION NEEDED
+
+1. **🔴 SEC EDGAR** — Both `cgi-bin/browse-edgar` and EFTS returned 403. The SEC has been migrating to EDGAR Next with new API endpoints. Check `~/social_scraper/scrapers/sec_edgar/` — update User-Agent to comply with SEC requirements (`User-Agent: CompanyName admin@email.com`). Consider migrating to `api.edgarfiling.sec.gov` or `data.sec.gov` endpoints.
+
+2. **🔴 Reuters RSS** — Officially dead since 2020, workarounds failing. In `~/social_scraper/config/sources.yaml`, either:
+   - Replace with a third-party RSS generator service (e.g., rss.app)
+   - Switch to direct web scraping of reuters.com
+   - Use Reuters API if you have a commercial license
+
+## WATCH LIST
+
+- **FRED API v2** — Monitor for v1 sunset announcement. Consider proactive migration.
+- **Reddit API** — Tighter approvals since Jan 2026. If scraper breaks, may need to re-apply or switch to paid tier.
+- **GitHub API** — New version 2026-03-10 has breaking changes. Current version safe for 24+ months but plan migration.
+- **Discord** — E2EE (DAVE) requirement for voice since March 1. Permission splits may affect bot.

+# Social Scraper — Daily Source Health Report
+**Date:** 2026-04-09
+
+---
+
+## STRUCTURED DATA COLLECTORS
+
+### Indian Economy
+🟢 **RBI Website** — Accessible. Updated April 8, 2026. Exchange rates, monetary policy statements current.
+🔴 **RBI DBIE** — TLS certificate error on `dbie.rbi.org.in` (ERR_TLS_CERT_ALTNAME_INVALID). New domain `data.rbi.org.in/DBIE/` loads an Angular SPA but blocks automation (right-click disabled, F12 blocked). **Config still uses old URL. STILL UNFIXED from March 23 report.**
+🟡 **NSE India** — Timeout on fetch (aggressive anti-bot). Likely operational but requires browser-level scraping.
+🟢 **BSE India** — Accessible. Corporate announcements, market data, IPO, derivatives sections present. Angular SPA with dynamic content.

+
+---
+
+## MESSAGING CHANNELS
+
+🟡 **Telegram** — Not verifiable via fetch. Manual check recommended.

+
+---
+
+## CONNECTORS
+
+🟡 **DragonScope** — Internal API, not publicly reachable. Manual verification needed.
+🟡 **LiquiFi** — Internal API, not publicly reachable. Manual verification needed.
+
+---
+
+## IMMEDIATE ACTION NEEDED
+
+1. **🔴 RBI DBIE (PERSISTENT — unfixed since March 23)**
+   - TLS cert invalid on old URL, new portal blocks automation
+   - Files to update:
+     - `~/social_scraper/config/sources.yaml:8` — change `base_url` to `https://data.rbi.org.in/DBIE`
+     - `~/social_scraper/collectors/rbi_dbie.py:22` — update `BASE_URL`
+     - `~/social_scraper/run_collectors.py:58` — update hardcoded URL
+     - `~/social_scraper/monitoring/health/source_health_checker.py:99,542` — update check URLs
+     - `~/social_scraper/monitoring/health/structure_validator.py:198` — update validation URL
+     - `~/social_scraper/monitoring/health/baselines/rbi_dbie.json:2` — update baseline URL
+   - **WARNING**: New portal is Angular SPA with anti-automation. Collector may need Playwright/Selenium or API reverse-engineering.
+
+2. **🔴 SEC EDGAR (PERSISTENT — unfixed since March 24)**
+   - Both `cgi-bin/browse-edgar` AND `data.sec.gov` returning 403
+   - Files: `~/social_scraper/scrapers/sec_scraper.py:53,140`
+   - Fix: Set User-Agent to `"CompanyName admin@email.com"` per SEC requirements. Migrate to `efts.sec.gov/LATEST/` or `data.sec.gov` with proper headers.
+
+3. **🔴 data.gov.in — NEW BREAKAGE**
+   - API returning 403 Forbidden (was working on March 24)
+   - File: `~/social_scraper/collectors/data_gov_in.py`
+   - Check if API key is still valid. May need re-registration or new auth mechanism.
+
+4. **🔴 Reuters RSS (PERSISTENT — unfixed since March 24)**
+   - `feeds.reuters.com` completely unreachable
+   - File: `~/social_scraper/config/sources.yaml:127-130` — remove or replace reuters feeds
+   - Options: third-party RSS generator, direct scraping, or commercial Reuters API
+
+## WATCH LIST
+
+- **FRED API** — Homepage 403 (bot blocking), API key-based access likely still fine. Monitor.
+- **IMF Data** — New portal may require updated access patterns. Check `~/social_scraper/collectors/imf_data.py`.

+
+**Critical issues requiring immediate attention: 4**
+**Items needing investigation: 6**
+
+---
+
+## 1. STRUCTURED DATA COLLECTORS
+
+### 1.1 RBI DBIE (collectors/rbi_dbie.py)
+- **ENDPOINT STATUS:** DOWN (TLS certificate error on dbie.rbi.org.in)
+- **STRUCTURE:** UNKNOWN — cannot verify due to TLS failure
+- **AUTH REQUIREMENTS:** UNCHANGED
+- **NEW FEATURES:** None detected
+- **RECOMMENDATION:** **INVESTIGATE IMMEDIATELY** — TLS cert alt-name mismatch on `https://dbie.rbi.org.in/DBIE`. RBI may have updated their SSL certificate or moved the portal. Check if the data portal has migrated to `https://data.rbi.org.in` (new RBI data platform detected in web search). The new platform at `data.rbi.org.in` may be the replacement.
+- **FILE TO EDIT:** `collectors/rbi_dbie.py` — update `BASE_URL` if portal has migrated
+
+### 1.2 RBI Circulars (collectors/rbi_circulars.py)
+- **ENDPOINT STATUS:** UP
+- **STRUCTURE:** UNCHANGED — Standard HTML with press releases under `../Scripts/BS_PressReleaseDisplay.aspx`, notifications/circulars organized by function codes, jQuery-driven accordion menus
+- **AUTH REQUIREMENTS:** UNCHANGED
+- **NEW FEATURES:** RBI issued new Digital Banking Channels Authorization Framework effective Jan 2026, and Digital Payment Authentication Framework effective Apr 1, 2026 — may generate high volume of new circulars
+- **RECOMMENDATION:** No action needed on collector. Consider adding filters for DPDP Act compliance circulars.
+- **FILE TO EDIT:** None
+
+### 1.3 NSE Bhavcopy (collectors/nse_bhavcopy.py)
+- **ENDPOINT STATUS:** CHANGED (timeout on direct fetch — heavy anti-bot)
+- **STRUCTURE:** LIKELY CHANGED — NSE has implemented static IP mandate effective April 1, 2026 for all API access. SEBI circular mandates whitelisted static IPs for API connections.
+- **AUTH REQUIREMENTS:** **NEW RESTRICTIONS DETECTED** — NSE now rejects API calls from non-whitelisted/dynamic IPs. Cookie-based session approach in `nse_bhavcopy.py` may no longer work.
+- **NEW FEATURES:** Enhanced security: Cloudflare Turnstile challenges, stricter rate limiting, request validation
+- **RECOMMENDATION:** **UPDATE COLLECTOR URGENTLY** — The current approach of fetching cookies then hitting `/api/fiidiiTradeReact` and `/api/historical/cm/equity` may be completely blocked. Need to: (1) Register a static IP with your broker/NSE, (2) Update User-Agent and headers, (3) Consider using official data vendor API (TrueData, etc.) as fallback
+- **FILE TO EDIT:** `collectors/nse_bhavcopy.py` lines 23-27 (headers), lines 29-31 (cookie fetch)
+
+### 1.4 BSE API (collectors/bse_api.py)
+- **ENDPOINT STATUS:** UP
+- **STRUCTURE:** UNCHANGED — Angular-based SPA, API endpoints intact: `/corporates/anndet_new.aspx?newsid=`, `/markets/equity/searchsecurity.aspx`, `/markets/debt/debt_corporate_EOD.aspx`, `/corporates/ann.html`
+- **AUTH REQUIREMENTS:** UNCHANGED
+- **NEW FEATURES:** None detected
+- **RECOMMENDATION:** No action needed
+- **FILE TO EDIT:** None
+
+### 1.5 CCIL Rates (collectors/ccil_rates.py)
+- **ENDPOINT STATUS:** UP
+- **STRUCTURE:** UNCHANGED — Money market data (Call, Repo, TREPS rates with WAR, volumes), G-Sec NDS-OM data, Forex FX-Clear (USD/INR spot with SPOT, C-SPOT, R-SPOT instruments), MIBOR-OIS derivatives via ASTROID platform, ZCYC rates section present
+- **AUTH REQUIREMENTS:** UNCHANGED
+- **NEW FEATURES:** Interactive charts with 60-minute lookback windows, additional derivative instruments (forwards, NDFs, swaptions)
+- **RECOMMENDATION:** No action needed on core collector. Consider adding NDF and swaption data collection.
+- **FILE TO EDIT:** None (optional: `collectors/ccil_rates.py` to add NDF data)
+
+### 1.6 FRED API (collectors/fred_api.py)
+- **ENDPOINT STATUS:** CHANGED
+- **STRUCTURE:** UNCHANGED (JSON response format same)
+- **AUTH REQUIREMENTS:** **CHANGED** — FRED launched API Version 2 in November 2025. Strict API key requirements now enforced on `/data/` endpoint. DEMO_KEY returns 403 — real API key mandatory for all programmatic access.
+- **NEW FEATURES:** ALFRED archival data no longer saveable to user accounts (as of Jan 5, 2026)
+- **RECOMMENDATION:** Verify `FRED_API_KEY` env var is set and valid. The collector already requires an API key (line 31 checks for it). No code changes needed if key is valid. **Test with actual key to confirm.**
+- **FILE TO EDIT:** None (verify API key is configured)
+
+### 1.7 SEBI Circulars (collectors/sebi_circulars.py)
+- **ENDPOINT STATUS:** UP
+- **STRUCTURE:** MODIFIED — Circulars listing now at `HomeAction.do?doListing=yes&sid=1&ssid=2&smid=0`, uses two-column layout (Year | Rule Name), "Updated List" and "Historical Data" toggle options added, breadcrumb navigation added
+- **AUTH REQUIREMENTS:** UNCHANGED
+- **NEW FEATURES:** New SEBI algo trading regulations framework effective April 2026
+- **RECOMMENDATION:** Verify collector parses the `doListing` action URL format. Check if `ssid` parameter maps correctly to circulars (ssid=2 is Rules, check ssid for circulars/orders).
+- **FILE TO EDIT:** `collectors/sebi_circulars.py` — verify URL construction matches current page structure
+
+### 1.8 data.gov.in (collectors/data_gov_in.py)
+- **ENDPOINT STATUS:** DOWN (403 Forbidden)
+- **STRUCTURE:** UNKNOWN
+- **AUTH REQUIREMENTS:** POSSIBLY CHANGED — API requires authorized API key; portal may have updated access policies
+- **NEW FEATURES:** API Setu platform (`apisetu.gov.in`) is a newer government API gateway that may offer alternative access paths
+- **RECOMMENDATION:** **INVESTIGATE** — Check if `DATA_GOV_API_KEY` is still valid. Portal may have migrated or tightened access. Consider API Setu as supplementary source. Also check `datagovindia` Python package for updated endpoints.
+- **FILE TO EDIT:** `collectors/data_gov_in.py`
+
+### 1.9 World Bank API (collectors/world_bank.py)
+- **ENDPOINT STATUS:** UP
+- **STRUCTURE:** UNCHANGED — JSON array with metadata + data objects, pagination working (66 pages for India GDP), standard fields (indicator, country, date, value, ISO3, unit, obs_status, decimal)
+- **AUTH REQUIREMENTS:** UNCHANGED (no auth needed)
+- **NEW FEATURES:** None
+- **RECOMMENDATION:** No action needed
+- **FILE TO EDIT:** None
+
+### 1.10 IMF Data (collectors/imf_data.py)
+- **ENDPOINT STATUS:** DOWN (403 Forbidden on data.imf.org)
+- **STRUCTURE:** POSSIBLY CHANGED — IMF now operates three API systems: (1) SDMX 2.1 at `sdmxcentral.imf.org/ws/public/sdmxapi/rest`, (2) SDMX 3.0 at `sdmxcentral.imf.org/sdmx/v2`, (3) DataMapper at `imf.org/external/datamapper/api`
+- **AUTH REQUIREMENTS:** POSSIBLY CHANGED
+- **NEW FEATURES:** SDMX 3.0 API available, Structure Map for cross-dataset conversion
+- **RECOMMENDATION:** **INVESTIGATE** — Check if collector uses `data.imf.org` directly or the SDMX Central API. May need to switch to `sdmxcentral.imf.org` endpoints.
+- **FILE TO EDIT:** `collectors/imf_data.py`
+
+---
+
+## 2. RSS FEEDS (collectors/rss_feeds.py)
+
+### Feed-by-Feed Status
+
+| # | Feed Name | URL | Status | Structure | Action |
+|---|---|---|---|---|---|
+| 1 | reuters_business | feeds.reuters.com/reuters/businessNews | **BROKEN** | N/A — feed domain unreachable | **REPLACE** |
+| 2 | reuters_markets | feeds.reuters.com/reuters/marketsNews | **BROKEN** | N/A — same domain | **REPLACE** |
+| 3 | et_economy | economictimes.indiatimes.com/.../rssfeedstopstories.cms | **BLOCKED** | Cannot fetch (anti-bot) | Investigate |
+| 4 | et_markets | economictimes.indiatimes.com/markets/rssfeeds/1977021501.cms | **BLOCKED** | Cannot fetch (anti-bot) | Investigate |
+| 5 | mint_economy | livemint.com/rss/economy | **BLOCKED** | Cannot fetch | Investigate |
+| 6 | mint_markets | livemint.com/rss/markets | **BLOCKED** | Same as above | Investigate |
+| 7 | moneycontrol | moneycontrol.com/rss/latestnews.xml | **BLOCKED** | Cannot fetch | Investigate |
+| 8 | rbi_press | rbi.org.in/Scripts/BS_PressReleaseDisplay.aspx | UP | **Not RSS** — HTML page | Verify parser handles HTML |
+| 9 | fed_press | federalreserve.gov/feeds/press_all.xml | **UP** | UNCHANGED — RSS 2.0, `<item>` with title/link/description/pubDate/guid/category, 20 items | No action |
+| 10 | ecb_press | ecb.europa.eu/rss/press.html | **UP** | MODIFIED — Valid RSS 2.0, 14 items, but **no `<description>` in items** (only title/link/pubDate/guid) | Check parser handles missing description |
+| 11 | coindesk | coindesk.com/arc/outboundfeeds/rss/ | **DOWN** (403) | Forbidden | **REPLACE or add auth** |
+| 12 | cnbc | search.cnbc.com/rs/search/combinedcms/view.xml... | **UP** | UNCHANGED — Standard RSS 2.0, title/link/description/pubDate/guid, 30 items, includes `<metadata:type>` and `<metadata:sponsored>` | No action |
+| 13 | ft_markets | ft.com/markets?format=rss | **LIKELY BLOCKED** | FT is paywalled, RSS likely requires auth | Investigate |
+| 14 | arxiv_qfin | rss.arxiv.org/rss/q-fin | **UP** | UNCHANGED — 18 items, title/link/description/categories, properly formatted | No action |
+
+### Critical RSS Issues
+
+1. **Reuters feeds are dead** — Reuters officially killed RSS in June 2020. The `feeds.reuters.com` domain has been fully decommissioned. **Must replace** with alternatives like Reuters Wire via API, or use third-party RSS generators (RSS.app, FiveFilters).
+
+2. **CoinDesk returning 403** — CoinDesk may have added Cloudflare protection or deprecated the `/arc/outboundfeeds/rss/` path.
+
+3. **Indian news sites (ET, Mint, MoneyControl)** — These appear blocked when fetched externally but may work from Indian IP addresses. Verify from the deployment environment.
+
+4. **ECB feed lacks descriptions** — The ECB RSS feed no longer includes `<description>` tags. The RSS collector at `rss_feeds.py:30` uses `_strip_html()` on descriptions — ensure it handles `None` gracefully.
+
+---
+
+## 3. SOCIAL SCRAPERS
+
+### 3.1 Reddit (scrapers/reddit_scraper.py)
+- **ENDPOINT STATUS:** CHANGED
+- **STRUCTURE:** Reddit's `.json` endpoint (used by the scraper) still works for read-only access without API key. However, Reddit deprecated r/all in April 2026 and shifted to algorithmic feeds.
+- **AUTH REQUIREMENTS:** CHANGED — Free tier limited to non-commercial use. Commercial use requires Standard tier ($12,000/year, 100 req/min). Scraping without API key may trigger rate limits more aggressively.
+- **NEW FEATURES:** r/all deprecated, engagement-optimized feeds
+- **RECOMMENDATION:** Verify `.json` endpoint still returns data for target subreddits (wallstreetbets, cryptocurrency, stocks). Consider switching to authenticated API if rate limits are hit.
+- **FILE TO EDIT:** `scrapers/reddit_scraper.py`
+
+### 3.2 Hacker News (scrapers/hackernews_scraper.py)
+- **ENDPOINT STATUS:** UP
+- **STRUCTURE:** UNCHANGED — Firebase API at `hacker-news.firebaseio.com/v0/` returns JSON arrays of story IDs as expected
+- **AUTH REQUIREMENTS:** UNCHANGED (no auth needed)
+- **RECOMMENDATION:** No action needed
+- **FILE TO EDIT:** None
+
+### 3.3 YouTube (scrapers/youtube_scraper.py)
+- **ENDPOINT STATUS:** UP (API v3 still active)
+- **STRUCTURE:** UNCHANGED
+- **AUTH REQUIREMENTS:** UNCHANGED — 10,000 units/day default quota remains
+- **NEW FEATURES:** No quota changes announced for 2026
+- **RECOMMENDATION:** No action needed. Monitor quota usage.
+- **FILE TO EDIT:** None
+
+### 3.4 Mastodon (scrapers/mastodon_scraper.py)
+- **ENDPOINT STATUS:** UP (federation APIs generally stable)
+- **STRUCTURE:** UNCHANGED
+- **AUTH REQUIREMENTS:** UNCHANGED
+- **RECOMMENDATION:** No action needed
+- **FILE TO EDIT:** None
+
+### 3.5 GitHub (scrapers/github_scraper.py)
+- **ENDPOINT STATUS:** UP
+- **STRUCTURE:** UNCHANGED — REST API v3 + trending
+- **AUTH REQUIREMENTS:** UNCHANGED
+- **RECOMMENDATION:** No action needed
+- **FILE TO EDIT:** None
+
+### 3.6 SEC EDGAR (scrapers/sec_scraper.py)
+- **ENDPOINT STATUS:** CHANGED
+- **STRUCTURE:** MODIFIED — SEC released EDGAR Release 26.0.1 and 26.1 with API updates. EDGAR full-text search API (`efts.sec.gov`) returns 403 from external requests (may require User-Agent with email as per SEC policy).
+- **AUTH REQUIREMENTS:** CHANGED — SEC now requires `User-Agent` header with company name and email. The `data.sec.gov` RESTful APIs (submissions, XBRL) remain keyless.
+- **NEW FEATURES:** EDGAR API Development Toolkit updated, EDGAR Beta environment for previewing API changes, Operational Status API with new degraded service statuses
+- **RECOMMENDATION:** **UPDATE** — Ensure SEC scraper sends proper `User-Agent: CompanyName contact@email.com` header. Check EDGAR Beta for upcoming changes. Consider using `data.sec.gov` RESTful APIs instead of EFTS for more reliable access.
+- **FILE TO EDIT:** `scrapers/sec_scraper.py` — add User-Agent header compliance
+
+### 3.7 Discord (scrapers/discord_scraper.py)
+- **ENDPOINT STATUS:** UP (Discord API Gateway generally stable)
+- **STRUCTURE:** UNCHANGED
+- **AUTH REQUIREMENTS:** UNCHANGED — requires bot token
+- **RECOMMENDATION:** No action needed
+- **FILE TO EDIT:** None
+
+### 3.8 Dark Web (scrapers/darkweb_scraper.py)
+- **ENDPOINT STATUS:** DEPENDENT ON TOR PROXY
+- **STRUCTURE:** N/A — varies by source
+- **AUTH REQUIREMENTS:** N/A
+- **RECOMMENDATION:** Verify Tor SOCKS5 proxy (docker service `tor` on port 9050) is running and can establish circuits
+- **FILE TO EDIT:** None
+
+### 3.9 Web Scraper (scrapers/web_scraper.py)
+- **ENDPOINT STATUS:** VARIES BY TARGET
+- **STRUCTURE:** N/A
+- **RECOMMENDATION:** General anti-bot measures (Cloudflare, DataDome) continue to tighten across the web. Ensure scraper handles JS challenges.
+- **FILE TO EDIT:** None
+
+### 3.10 Central Banks (scrapers/centralbank_scraper.py)
+- **ENDPOINT STATUS:** UP
+- **STRUCTURE:** UNCHANGED — Fed press RSS feed verified working and properly formatted
+- **RECOMMENDATION:** No action needed
+- **FILE TO EDIT:** None
+
+---
+
+## 4. MESSAGING SOURCES
+
+### 4.1 Telegram (collectors/telegram_channels.py)
+- **ENDPOINT STATUS:** UP (API access via api_id/api_hash)
+- **STRUCTURE:** UNCHANGED
+- **AUTH REQUIREMENTS:** UNCHANGED
+- **RECOMMENDATION:** No action needed. Verify channels (BloombergMarketsLive, financialjuice, WallStreetSilverOfficial, raboratory) are still active.
+- **FILE TO EDIT:** None
+
+### 4.2 Twitter/X (collectors/twitter_lists.py + scrapers/twitter_scraper.py)
+- **ENDPOINT STATUS:** CHANGED
+- **STRUCTURE:** MODIFIED — X migrated from in-house bot detection to Cloudflare Turnstile challenges. Defensive changes every 2-4 weeks break DIY scrapers.
+- **AUTH REQUIREMENTS:** **SIGNIFICANTLY CHANGED** — Authenticated sessions required for most profile timelines and all search results. Cookie-based scraping (`twikit` library) may break frequently. Legal risk: >1M posts/24h triggers $15,000 liquidated damages.
+- **NEW FEATURES:** Cloudflare Turnstile integration, stricter rate limiting
+- **RECOMMENDATION:** **HIGH RISK** — Cookie-based scraping via twikit is increasingly fragile. Options: (1) Keep twikit but accept frequent breakages and re-auth, (2) Switch to a specialized scraping API service, (3) Reduce scraping frequency to minimize detection. **Monitor twikit library updates closely.**
+- **FILE TO EDIT:** `collectors/twitter_lists.py`, `scrapers/twitter_scraper.py`
+
+---
+
+## 5. CONNECTORS
+
+### 5.1 DragonScope Connector (connectors/dragonscope.py)
+- **STATUS:** Code review — HEALTHY
+- **Redis Push:** Uses `market:{category}` keys + `market:updates` pub/sub channel. Format compatible.
+- **API Push:** Falls back to `POST /api/data/{category}`. Endpoint pattern is standard.
+- **Platform mapping:** Complete — all 12 platforms mapped to DragonScope categories
+- **RECOMMENDATION:** No action needed
+- **FILE TO EDIT:** None
+
+### 5.2 LiquiFi Connector (connectors/liquifi.py)
+- **STATUS:** Code review — HEALTHY
+- **Treasury keywords:** Comprehensive coverage of rates, regulatory, forex, bonds, liquidity, banking, macro_india
+- **Push targets:** WebSocket `/ws/rates` + REST API
+- **RECOMMENDATION:** No action needed. Consider adding DPDP Act and digital payment keywords given RBI's April 2026 Digital Payment Authentication Framework.
+- **FILE TO EDIT:** `connectors/liquifi.py` (optional — add DPDP keywords)
+
+### 5.3 Router (connectors/router.py)
+- **STATUS:** Code review — HEALTHY
+- **Classification logic:** Platform-based default + content-based override, working correctly
+- **Routing:** DragonScope (Reddit, Discord, YouTube, HN, Mastodon, GitHub), LiquiFi (Central Banks), Both (Twitter, Telegram, RSS, Web, SEC, DarkWeb), All → Kafka
+- **RECOMMENDATION:** No action needed. All content categories covered.
+- **FILE TO EDIT:** None
+
+---
+
+## 6. INFRASTRUCTURE
+
+### 6.1 Celery Beat Schedules
+
+**Schedule source:** `core/scheduler.py` (canonical) reads from `config/sources.yaml`.

+### 6.2 Docker Compose (docker-compose.yml)
+
+**Services defined:** 10 (postgres, redis, minio, zookeeper, kafka, tor, api, worker, beat, nlp-worker, flower)
+
+**Port conflicts:** NONE detected
+| Service | Port | Status |
+|---|---|---|
+| postgres | 5432 | OK |
+| redis | 6379 | OK |
+| minio | 9000, 9001 | OK |
+| zookeeper | 2181 | OK |
+| kafka | 9092 | OK |
+| tor | 9050, 8118 | OK |
+| api | 8000 | OK |
+| flower | 5555 | OK |
+
+**Health checks:** postgres (pg_isready), redis (redis-cli ping), minio (mc ready), kafka (kafka-topics --list), api (curl health endpoint) — ALL CONFIGURED.
+
+**Potential issue:** `nlp-worker` service does not have `restart: unless-stopped` set, unlike `worker` and `beat`. If it crashes, it won't restart automatically.
+
+---
+
+## 7. NEW DATA SOURCES & API CHANGES
+
+### New Sources Worth Adding
+
+1. **RBI Data Platform (data.rbi.org.in)** — New RBI digital data platform. May replace or supplement DBIE. **Investigate as potential new collector.**
+
+2. **API Setu (apisetu.gov.in)** — Government of India's centralized API gateway. Could provide alternative access to data.gov.in datasets with potentially better reliability.
+
+3. **TrueData Market Data API (truedata.in)** — Indian market data API covering NSE EQ, NSE Indices, NSE F&O, BSE EQ, BSE Indices, BSE F&O, MCX. Could serve as reliable fallback for NSE/BSE data if direct scraping breaks.
+
+4. **IMF SDMX Central (sdmxcentral.imf.org)** — SDMX 3.0 API available as modern alternative to data.imf.org.
+
+5. **SEC EDGAR data.sec.gov** — RESTful APIs for submissions and XBRL data, no auth needed, sub-second latency. More reliable than EFTS full-text search.
+
+### Key Platform Changes in 2026
+
+| Platform | Change | Impact | Urgency |
+|---|---|---|---|
+| NSE India | Static IP mandate (Apr 1, 2026) | API calls blocked from dynamic IPs | **CRITICAL** |
+| Reddit | r/all deprecated, algorithmic feeds | Discovery pattern changed | MEDIUM |
+| Twitter/X | Cloudflare Turnstile, auth-only search | Cookie scraping increasingly fragile | HIGH |
+| FRED | API v2 strict key enforcement | Need valid key | LOW (already handled) |
+| SEC EDGAR | Release 26.0.1 & 26.1, Beta API changes | New endpoints available | MEDIUM |
+| RBI | DBIE portal TLS issues | Data collection may be interrupted | **CRITICAL** |
+| Reuters | RSS feeds fully decommissioned (since 2020) | Two feed URLs broken | HIGH |
+| CoinDesk | 403 on RSS endpoint | Feed broken | MEDIUM |
+| RBI | Digital Payment Auth Framework (Apr 1, 2026) | High volume of new circulars expected | LOW |
+| SEBI | Algo trading regulations framework | New regulatory content | LOW |
+
+---
+
+## 8. PRIORITY ACTION ITEMS
+
+### P0 — Critical (Fix This Week)
+1. **NSE Bhavcopy collector** — Static IP mandate blocks API access. Register static IP or switch to data vendor. (`collectors/nse_bhavcopy.py`)
+2. **RBI DBIE collector** — TLS certificate error. Check if portal migrated to `data.rbi.org.in`. (`collectors/rbi_dbie.py`)
+3. **Reuters RSS feeds** — Dead since 2020, should have been replaced long ago. Remove or replace with alternative. (`config/sources.yaml` lines 127-131)
+
+### P1 — High (Fix Within 2 Weeks)
+4. **Twitter/X scraping** — Cloudflare Turnstile breaking cookie-based approach. Monitor twikit updates, consider reducing frequency. (`collectors/twitter_lists.py`, `scrapers/twitter_scraper.py`)
+5. **CoinDesk RSS** — 403 Forbidden. Find new feed URL or remove. (`config/sources.yaml` line 157)
+6. **SEC EDGAR scraper** — Add compliant User-Agent header. (`scrapers/sec_scraper.py`)
+
+### P2 — Medium (Fix Within Month)
+7. **data.gov.in collector** — 403 Forbidden. Verify API key, investigate API Setu alternative. (`collectors/data_gov_in.py`)
+8. **IMF Data collector** — 403 on data.imf.org. Consider SDMX Central endpoints. (`collectors/imf_data.py`)
+9. **ECB RSS feed** — Missing `<description>` tags. Verify parser handles None. (`collectors/rss_feeds.py`)
+10. **Indian news RSS feeds** — May work from Indian IPs; verify from deployment environment. (ET, Mint, MoneyControl)
+
+### P3 — Low (Backlog)
+11. Add `restart: unless-stopped` to `nlp-worker` service in `docker-compose.yml`
+12. Consider adding DPDP Act keywords to LiquiFi connector
+13. Explore new data sources: data.rbi.org.in, API Setu, TrueData, IMF SDMX 3.0, SEC data.sec.gov REST
+14. Add NDF/swaption data to CCIL collector

+**NOTE:** Items 4-8 were tested from non-Indian IPs. Many Indian government/financial sites implement geo-restrictions. These MUST be verified from production infrastructure before taking action.
+
+---
+
+## 1. STRUCTURED DATA COLLECTORS
+
+### 1.1 RBI DBIE (collectors/rbi_dbie.py) — INVESTIGATE
+- **ENDPOINT STATUS:** DEGRADED — `dbie.rbi.org.in` returns TLS certificate error (`ERR_TLS_CERT_ALTNAME_INVALID`). The certificate no longer covers the `dbie.rbi.org.in` hostname. Alternate portal `data.rbi.org.in` loads but appears to be a JS-heavy SPA with minimal server-side HTML.
+- **STRUCTURE:** POTENTIALLY BROKEN — cannot connect via plain HTTPS due to cert mismatch. RBI main site now references `data.rbi.org.in` as the data portal, suggesting DBIE may have been consolidated.
+- **AUTH REQUIREMENTS:** UNKNOWN (cannot connect to verify)
+- **NEW FEATURES:** `data.rbi.org.in` may be the new canonical endpoint (SPA-based)
+- **RECOMMENDATION:** INVESTIGATE from production server — TLS cert errors may be intermittent or CDN-specific. If `dbie.rbi.org.in` is permanently broken, migrate to `data.rbi.org.in` with headless browser support. As stopgap, Weekly Statistical Supplement data is available on main `rbi.org.in` publications section.
+- **FILE TO EDIT:** ~/social_scraper/collectors/rbi_dbie.py (line with base_url if migration needed)
+- **NOTE:** Test from Indian IP — some issues may be geo-specific
+
+### 1.2 RBI Circulars (collectors/rbi_circulars.py)
+- **ENDPOINT STATUS:** UP
+- **STRUCTURE:** UNCHANGED — press releases, notifications, circulars sections intact
+- **AUTH REQUIREMENTS:** UNCHANGED
+- **NEW FEATURES:** April 2026 DPDP Act advisory and Digital Payment Authentication Directions published — verify these are being ingested
+- **RECOMMENDATION:** No action (verify new circulars are captured)
+- **FILE TO EDIT:** N/A
+
+### 1.3 NSE (collectors/nse_bhavcopy.py)
+- **ENDPOINT STATUS:** UP (heavy anti-bot protection active)
+- **STRUCTURE:** UNCHANGED — bhavcopy download pattern intact
+- **AUTH REQUIREMENTS:** UNCHANGED for data scraping. Note: NSE algo trading API now requires static IP + whitelisted keys (April 2026) but this does NOT affect website data collection
+- **NEW FEATURES:** None affecting data collection
+- **RECOMMENDATION:** Monitor — NSE frequently tightens anti-bot; add better 403/captcha handling
+- **FILE TO EDIT:** ~/social_scraper/collectors/nse_bhavcopy.py (low priority)
+
+### 1.4 BSE (collectors/bse_api.py) — INVESTIGATE
+- **ENDPOINT STATUS:** PARTIALLY UP — main site loads but is a fully client-rendered SPA (minimal server-side HTML)
+- **STRUCTURE:** MODIFIED — old REST API at `api.bseindia.com/BseIndiaAPI/api/` now returns **301 Moved Permanently** redirecting to `www.bseindia.com/members/showinterest.aspx`. This indicates BSE has deprecated or reorganized their public API endpoints.
+- **AUTH REQUIREMENTS:** CHANGED — API redirect to `/members/` path suggests some endpoints may now require member login
+- **NEW FEATURES:** Cannot fully assess due to SPA rendering
+- **RECOMMENDATION:** INVESTIGATE — re-map API endpoints by inspecting network traffic from BSE website. Check if `www.bseindia.com/download/BhseCsv/Equity/` still serves bhavcopy CSVs directly. May need headless browser approach for SPA content.
+- **FILE TO EDIT:** ~/social_scraper/collectors/bse_api.py
+- **NOTE:** Test API endpoints from production server — may be IP/geo-specific blocking
+
+### 1.5 CCIL (collectors/ccil_rates.py)
+- **ENDPOINT STATUS:** UP — site fully operational with rich market data
+- **STRUCTURE:** UNCHANGED for core data (Money Market, G-Sec, Forex, Derivatives tables)
+- **AUTH REQUIREMENTS:** UNCHANGED — public data accessible without login
+- **NEW FEATURES DETECTED:**
+  - New swap instruments beyond 12 months on FX-CLEAR
+  - Portfolio Compression service for IRS trades (84.92% compression)
+  - Margin Calculator for USDINR Forex Forward and Rupee IRS
+  - ZCYC (Zero Coupon Yield Curve) parameters available
+  - Real-time data refresh intervals selectable (2, 5, 10, 15, 30, 60 min)
+- **FBIL WARNING:** `/web/ccil/fbil-reference-rate` returns 404. `fbil.org.in` appears unreachable (ECONNREFUSED). FBIL rates may have moved — investigate new URL.
+- **RECOMMENDATION:** Add new data products as scraping targets. **Investigate FBIL reference rates location** — critical for treasury operations.
+- **FILE TO EDIT:** ~/social_scraper/collectors/ccil_rates.py (add new data products, fix FBIL URL)
+
+### 1.6 FRED API (collectors/fred_api.py)
+- **ENDPOINT STATUS:** UP (403 with DEMO_KEY is expected; real API keys work)
+- **STRUCTURE:** UNCHANGED — v1 API responds correctly with valid keys
+- **AUTH REQUIREMENTS:** UNCHANGED — API key required (already configured via `${FRED_API_KEY}`)
+- **SERIES STATUS:** All 11 series IDs confirmed valid: FEDFUNDS, CPIAUCSL, DGS10, DGS2, DTWEXBGS, UNRATE, GDP, SOFR, T10Y2Y, VIXCLS, BAMLH0A0HYM2
+- **NEW FEATURES:** FRED API v2 documentation page exists but no forced migration timeline detected
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** N/A
+
+### 1.7 SEBI (collectors/sebi_circulars.py) — INVESTIGATE
+- **ENDPOINT STATUS:** TIMEOUT — all URLs tested (homepage, `/legal/circulars.html`, `/enforcement/orders.html`) time out after 60s from external fetch. May indicate aggressive rate limiting, WAF protection, or geo-blocking.
+- **STRUCTURE:** UNABLE TO VERIFY from external network
+- **AUTH REQUIREMENTS:** UNKNOWN — may now require browser-like headers or JS execution
+- **NEW FEATURES:** Cannot assess
+- **RECOMMENDATION:** INVESTIGATE from production server (Indian IP). If confirmed blocking, add browser-like headers or headless browser fallback. SEBI circulars are often mirrored on financial news sites as fallback.
+- **FILE TO EDIT:** ~/social_scraper/collectors/sebi_circulars.py (if blocking confirmed)
+- **NOTE:** This may be geo-restriction — test from Indian infrastructure first
+
+### 1.8 data.gov.in (collectors/data_gov_in.py) — INVESTIGATE
+- **ENDPOINT STATUS:** DEGRADED — main site and datasets page return HTTP 403 Forbidden from external network. API endpoint `api.data.gov.in` returns 404 Not Found. OGPL APIs page also returns 403.
+- **STRUCTURE:** UNABLE TO VERIFY — blanket 403 blocks access
+- **AUTH REQUIREMENTS:** POSSIBLY CHANGED — 403 may indicate: (a) geo-restriction to Indian IPs, (b) mandatory API key even for browsing, or (c) platform migration
+- **NEW FEATURES:** Cannot assess
+- **RECOMMENDATION:** INVESTIGATE from production server (Indian IP). If the OGPL API has been deprecated, check NIC announcements for migration notices. API Setu (`apisetu.gov.in`) may be an alternative.
+- **FILE TO EDIT:** ~/social_scraper/collectors/data_gov_in.py (if platform migrated)
+- **NOTE:** Likely geo-restriction — test from Indian IP before taking action
+
+### 1.9 World Bank API (collectors/world_bank.py)
+- **ENDPOINT STATUS:** UP
+- **STRUCTURE:** UNCHANGED — v2 API responding correctly
+  - Pagination metadata: page, pages, per_page, total, lastupdated (2026-04-08)
+  - Data array with indicator, country, year, value fields intact
+  - All indicators valid: NY.GDP.MKTP.CD, FP.CPI.TOTL.ZG, BN.CAB.XOKA.CD
+  - All countries accessible: IN, US, CN, GB, JP, DE
+- **AUTH REQUIREMENTS:** UNCHANGED — no auth needed
+- **NEW FEATURES:** None detected
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** N/A
+
+### 1.10 IMF Data (collectors/imf_data.py) — CRITICAL
+- **ENDPOINT STATUS:** DOWN — `dataservices.imf.org` DECOMMISSIONED (November 2025)
+- **STRUCTURE:** BROKEN — all requests to old endpoint timeout
+- **AUTH REQUIREMENTS:** CHANGED — new SDMX 3.0 API at `sdmxcentral.imf.org`
+- **NEW FEATURES:** New SDMX Central API with hundreds of dataflows (IFS, BOP, DOT confirmed available)
+- **RECOMMENDATION:** REWRITE COLLECTOR — migrate from old REST JSON API to new SDMX Central API
+  - Old: `http://dataservices.imf.org/REST/SDMX_JSON.svc/CompactData/{dataset}/...`
+  - New primary: `https://sdmxcentral.imf.org/ws/public/sdmxapi/rest/data/STA/{dataset}/...`
+  - New fallback: `https://www.imf.org/external/datamapper/api/v1/{indicator}/{country}` (confirmed working, returns JSON)
+  - Consider using the `sdmx1` Python library for SDMX 3.0 parsing
+- **FILE TO EDIT:** ~/social_scraper/collectors/imf_data.py (line 14: BASE_URL)
+
+### 1.11 Telegram (collectors/telegram_channels.py)
+- **ENDPOINT STATUS:** Requires runtime API credentials (api_id/api_hash) — cannot test externally
+- **STRUCTURE:** Assumed UNCHANGED — Telegram Bot API and MTProto stable
+- **AUTH REQUIREMENTS:** UNCHANGED
+- **RECOMMENDATION:** No action (verify in production)
+- **FILE TO EDIT:** N/A
+
+### 1.12 Twitter Lists (collectors/twitter_lists.py)
+- **ENDPOINT STATUS:** FRAGILE — twikit cookie-based auth breaks every 2-4 weeks
+- **STRUCTURE:** CHANGED — X (Twitter) free API tier is now write-only (Feb 2026). Guest tokens bound to browser fingerprints. Datacenter IPs permanently banned
+- **AUTH REQUIREMENTS:** NEW RESTRICTIONS — paid API ($100/mo Basic) required for reliable read access
+- **NEW FEATURES:** Pay-per-use billing model
+- **RECOMMENDATION:** Investigate — verify twikit still functional, consider paid API ($100/mo Basic tier)
+- **FILE TO EDIT:** ~/social_scraper/collectors/twitter_lists.py, ~/social_scraper/scrapers/twitter_scraper.py
+

+
+## 2. RSS FEEDS (collectors/rss_feeds.py)
+
+### Working Feeds (10/14)
+
+| Feed | Status | Structure | Notes |
+|------|--------|-----------|-------|
+| et_economy | UP | RSS 2.0, 51 items | No `<description>` — title/link/guid/pubDate only |
+| et_markets | UP | RSS 2.0, 50 items | Has `<description>`, `<enclosure>` for images |
+| mint_economy | UP | RSS 2.0 + MRSS, 35 items | `<media:content>` for images |
+| mint_markets | UP | RSS 2.0 + MRSS, 35 items | Same structure as economy |
+| fed_press | UP | RSS 2.0, 20 items | Has `<category>` (5 types), latest: May 1, 2026 |
+| ecb_press | UP | RSS 2.0, 14 items | No `<description>` — title/link/guid/pubDate only |
+| coindesk | UP | RSS 2.0 rich, 25 items | `<dc:creator>`, empty `<content:encoded>`, TTL=5min |
+| cnbc | UP | RSS 2.0 + custom metadata, 30 items | `<metadata:type/id/sponsored>` fields |
+| ft_markets | UP | RSS 2.0 + dc, 25 items | GUIDs are UUIDs not URLs, TTL=15min |
+| arxiv_qfin | UP | RSS 2.0 + arxiv/dc, 0 items | Empty on weekends (has `<skipDays>` Sat/Sun) |
+
+### Broken Feeds (4/14) — ACTION REQUIRED
+
+| Feed | Status | Issue | Action |
+|------|--------|-------|--------|
+| **reuters_business** | **DOWN** | DNS dead — `feeds.reuters.com` permanently retired | Remove or replace (AP News RSS, RSSHub proxy) |
+| **reuters_markets** | **DOWN** | DNS dead — same domain | Remove or replace |
+| **moneycontrol** | **DOWN** | HTTP 403 — Akamai CDN bot block | Route via residential proxy or replace |
+| **rbi_press** | **NOT RSS** | HTML page, never was RSS | Switch to HTML scraper (BeautifulSoup) |
+
+**RECOMMENDATION:** Update `config/sources.yaml` RSS feeds list:
+- Remove reuters_business and reuters_markets entries
+- Add replacement feeds (e.g., AP News, Bloomberg RSS if available)
+- Change rbi_press to use HTML parsing, or remove from RSS collector and handle in rbi_circulars collector
+- For moneycontrol, test from production server (may be IP/geo-specific block)
+
+**FILE TO EDIT:** ~/social_scraper/config/sources.yaml (feeds section), ~/social_scraper/collectors/rss_feeds.py
+
+---
+
+## 3. SOCIAL SCRAPERS
+
+### 3.1 Reddit (scrapers/reddit_scraper.py)
+- **ENDPOINT STATUS:** UP — JSON API returns valid Listing objects with 108 fields per post
+- **STRUCTURE:** UNCHANGED — `data.children[]` array, pagination via `data.after` token
+- **AUTH REQUIREMENTS:** CHANGED — OAuth now enforced. Unauthenticated `.json` endpoint throttled to 10 req/min. OAuth free tier allows 100 req/min
+- **RECOMMENDATION:** Investigate — migrate to OAuth as primary path. At 10 req/min across 18 subreddits, throttling will hit during scan cycles
+- **FILE TO EDIT:** ~/social_scraper/scrapers/reddit_scraper.py
+
+### 3.2 Hacker News (scrapers/hackernews_scraper.py)
+- **ENDPOINT STATUS:** UP
+- **STRUCTURE:** UNCHANGED — Firebase API returns array of story IDs `[48002938, ...]`
+- **AUTH REQUIREMENTS:** UNCHANGED — no auth needed
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** N/A
+
+### 3.3 YouTube (scrapers/youtube_scraper.py)
+- **ENDPOINT STATUS:** UP
+- **STRUCTURE:** UNCHANGED — Data API v3, 10,000 units/day quota
+- **AUTH REQUIREMENTS:** UNCHANGED — quota increase requests now require compliance audit (1-6 weeks)
+- **RECOMMENDATION:** No action (existing `_QUOTA_COOLDOWN_SECONDS` mechanism sufficient)
+- **FILE TO EDIT:** N/A
+
+### 3.4 Mastodon (scrapers/mastodon_scraper.py) — ACTION REQUIRED
+- **ENDPOINT STATUS:** DOWN — HTTP 422 `"This method requires an authenticated user"`
+- **STRUCTURE:** BROKEN — public timeline API disabled for unauthenticated access
+- **AUTH REQUIREMENTS:** NEW RESTRICTION — OAuth bearer token now required
+- **RECOMMENDATION:** Update authentication — register app at mastodon.social/settings/applications, add OAuth token. Alternative: use `/api/v1/timelines/tag/:hashtag` endpoint or switch to a different instance
+- **FILE TO EDIT:** ~/social_scraper/scrapers/mastodon_scraper.py
+
+### 3.5 GitHub (scrapers/github_scraper.py)
+- **ENDPOINT STATUS:** UP — rate limits: core 60/hr (unauth), search 10/min, GraphQL requires auth
+- **STRUCTURE:** UNCHANGED
+- **AUTH REQUIREMENTS:** UNCHANGED — consider using PAT for 5000/hr core limit
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** N/A
+
+### 3.6 SEC EDGAR (scrapers/sec_scraper.py)
+- **ENDPOINT STATUS:** UP — requires User-Agent header (mandatory, must include contact info)
+- **STRUCTURE:** MODIFIED
+  - `/LATEST/search-index` endpoint: WORKS with compliant User-Agent (HTTP 200)
+  - `/LATEST/search` endpoint: NOW RETURNS `"Missing Authentication Token"` — may require new auth
+  - **NEW aggregations field** in responses: faceted search by form type, entity, SIC code, state
+  - **NEW query transparency** — parsed Elasticsearch query returned in response
+  - 18 source fields confirmed: adsh, biz_locations, ciks, display_names, file_date, form, sics, etc.
+- **AUTH REQUIREMENTS:** CHANGED — User-Agent now strictly mandatory; `/search` endpoint may need new auth
+- **NEW FEATURES:** EDGAR 26.0.1 (Feb 2026) + 26.1 (Mar 2026). Aggregations/faceted search. EDGAR Beta in preview
+- **RECOMMENDATION:** Verify scraper uses `/LATEST/search-index` (not `/LATEST/search`). Ensure User-Agent includes contact email. Consider leveraging new aggregations for enhanced filtering
+- **FILE TO EDIT:** ~/social_scraper/scrapers/sec_scraper.py (verify endpoint path + User-Agent)
+
+### 3.7 Discord (scrapers/discord_scraper.py)
+- **ENDPOINT STATUS:** UP
+- **STRUCTURE:** UNCHANGED for read-only message scraping
+- **AUTH REQUIREMENTS:** UNCHANGED — permission splits (PIN_MESSAGES, BYPASS_SLOWMODE) don't affect read-only bots
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** N/A
+
+### 3.8 Dark Web (scrapers/darkweb_scraper.py)
+- **ENDPOINT STATUS:** Requires Tor SOCKS5 proxy — cannot test externally
+- **STRUCTURE:** Assumed UNCHANGED

+---
+
+## 5. INFRASTRUCTURE
+
+### 5.1 Celery Beat Schedules
+- **STATUS:** CONSISTENT
+- **YAML-driven:** 13 sources in config/sources.yaml, all map to valid collector classes via `build_beat_schedule()`
+- **Hardcoded scrapers:** 12 scraper tasks in core/scheduler.py, all map to existing scraper files
+- **System tasks:** 9 operational tasks (process-articles, daily-digest, health-check, data-quality, route-to-destinations, push-stats, backpressure-check, retention-cleanup, generate-daily-report)
+- **Deprecated file:** scheduler/schedule.py properly deprecated with warnings, no conflict
+- **RECOMMENDATION:** No action

+- **Scraper tasks to scraper files:** All 12 mappings verified (class names found via grep)
+- **Orphaned entries:** None detected
+- **RECOMMENDATION:** No action
+
+---
+
+## 6. NEW DATA SOURCE OPPORTUNITIES
+
+| Source | Description | Effort | Auth Required |
+|--------|-------------|--------|---------------|
+| **mfdata.in** | Free Indian mutual fund NAV/holdings API (14K+ schemes, 18yr history) | Low | No |
+| **RSSHub proxy** | Self-hosted RSS proxy for Reuters and other paywalled feeds | Medium | No |
+| **EDGAR Operational Status API** | New endpoints for detecting EDGAR degraded service | Low | No |
+
+---
+
+## 7. PRIORITY ACTION ITEMS
+
+### CRITICAL (blocking data collection)
+| # | Issue | File | Action |
+|---|-------|------|--------|
+| 1 | IMF API decommissioned (Nov 2025) | `collectors/imf_data.py:14` | Rewrite to use `sdmxcentral.imf.org` SDMX 3.0 API |
+| 2 | Reuters RSS feeds dead (DNS failure) | `config/sources.yaml` | Remove reuters_business + reuters_markets, add replacements |

+
+### HIGH (degraded or at risk)
+| # | Issue | File | Action |
+|---|-------|------|--------|
+| 4 | Twitter/X twikit fragile, free API write-only | `scrapers/twitter_scraper.py` | Verify twikit works; evaluate $100/mo Basic tier |
+| 5 | Reddit unauthenticated throttled to 10 req/min | `scrapers/reddit_scraper.py` | Migrate to OAuth (100 req/min free tier) |
+| 6 | MoneyControl RSS blocked (Akamai 403) | `config/sources.yaml` | Test from prod server; proxy or replace |
+
+### INVESTIGATE FROM PRODUCTION (may be geo-specific — test from Indian IP before acting)
+| # | Issue | File | Action |
+|---|-------|------|--------|
+| 7 | RBI DBIE TLS cert error on `dbie.rbi.org.in`, possible migration to `data.rbi.org.in` | `collectors/rbi_dbie.py` | Test from prod; if broken, migrate to `data.rbi.org.in` (may need headless browser) |

+
+## 8. ECOSYSTEM CHANGES SUMMARY
+
+| Platform | Change | Impact |
+|----------|--------|--------|
+| Reddit | OAuth enforced, unauthenticated throttled to 10 req/min | MEDIUM |
+| Twitter/X | Free API write-only (Feb 2026), guest tokens browser-fingerprinted | HIGH |
+| SEC EDGAR | Releases 26.0.1 + 26.1, Beta environment in preview | LOW |
+| YouTube | No quota changes; quota increase needs compliance audit | NONE |
+| Discord | Permission splits (PIN, BYPASS_SLOWMODE); E2EE for calls | NONE |
+| NSE India | Algo trading: static IP + whitelisted keys required (April 2026) | LOW (data scraping unaffected) |
+| RBI | DPDP Act advisory + Digital Payment Auth Directions (April 2026) | LOW |
+| IMF | `dataservices.imf.org` decommissioned Nov 2025; migrated to SDMX 3.0 | CRITICAL |
+| Reuters | `feeds.reuters.com` domain permanently retired | CRITICAL |
+| Mastodon | Public timeline API requires authentication | HIGH |
+
+---
+
+---
+
+## 9. KEY TRENDS
+
+**Indian financial regulators migrating to SPA architectures:** Multiple Indian sources (BSE, potentially DBIE, data.gov.in) are moving from server-rendered HTML/REST APIs to client-rendered SPAs. This trend will eventually require headless browser infrastructure (Playwright/Puppeteer) for reliable data collection from Indian regulatory sites. Consider adding a shared headless browser service to the Docker stack.
+
+**Anti-bot protection intensifying:** NSE, MoneyControl, SEBI, and data.gov.in all show increased bot-detection measures. The scraper may need residential proxy rotation or browser fingerprint management for continued access.
+
+**Social platform APIs becoming more restrictive:** Reddit (OAuth enforcement), Twitter/X (pay-for-read), Mastodon (auth required) all moved toward more restrictive access in 2025-2026. The general trend is toward authenticated, rate-limited, paid access for any automated consumption.

+# Weekly Deep Source Validation Report
+**Date:** 2026-05-25 (Sunday)
+**Run by:** Automated scheduled task
+
+---
+
+## EXECUTIVE SUMMARY
+
+| Category | Total | UP/OK | CHANGED | DOWN/BROKEN | ACTION NEEDED |
+|----------|-------|-------|---------|-------------|---------------|
+| Structured Data Collectors | 10 | 5 | 3 | 2 | 5 |
+| RSS Feeds | 14 | 6 | 2 | 4 | 6 |
+| Social Scrapers | 10 | 4 | 3 | 1 | 4 |
+| Messaging | 2 | 1 | 1 | 0 | 1 |
+| Connectors | 3 | 3 | 0 | 0 | 0 |
+| Infrastructure | 2 | 2 | 0 | 0 | 0 |
+
+**Critical Issues (Immediate):**
+1. RBI DBIE URL has changed — `dbie.rbi.org.in` has TLS cert issues; new portal at `data.rbi.org.in`
+2. CCIL FBIL rates URL structure changed — old `/web/ccil/fbil-overnight-mibor` returns 404
+3. IMF legacy API (`dataservices.imf.org`) appears unresponsive — migrated to SDMX 3.0
+4. Reuters RSS feeds confirmed dead since 2020 — still configured in sources.yaml
+5. SEC EDGAR EFTS returning 403 — may need User-Agent update for EDGAR Next
+
+---
+
+## 1. RBI DBIE
+
+- **ENDPOINT STATUS:** CHANGED / DOWN
+- **STRUCTURE:** BROKEN — TLS certificate error on `dbie.rbi.org.in`. RBI has migrated to `data.rbi.org.in/DBIE/`
+- **AUTH REQUIREMENTS:** NEW URL discovered; may need updated headers
+- **NEW FEATURES:** RBI launched RBIDATA mobile app; new portal at `data.rbi.org.in` is the modernized DBIE
+- **RECOMMENDATION:** **Update collector URL immediately** — change `BASE_URL` from `https://dbie.rbi.org.in/DBIE` to `https://data.rbi.org.in/DBIE/`. Investigate new API structure.
+- **FILE TO EDIT:** `collectors/rbi_dbie.py` (line 24: `BASE_URL`) and `config/sources.yaml` (rbi_dbie.base_url)
+
+---
+
+## 2. RBI Circulars
+
+- **ENDPOINT STATUS:** UP
+- **STRUCTURE:** UNCHANGED — Press releases page still uses chronological list, year-based dropdown navigation, URL pattern `BS_PressReleaseDisplay.aspx?prid=[ID]`
+- **AUTH REQUIREMENTS:** UNCHANGED (no auth needed)
+- **NEW FEATURES:** None detected
+- **RECOMMENDATION:** No action needed
+- **FILE TO EDIT:** N/A
+
+---
+
+## 3. NSE India
+
+- **ENDPOINT STATUS:** DOWN (connection reset — heavy anti-bot)
+- **STRUCTURE:** CANNOT VERIFY — NSE's aggressive anti-bot protection blocks automated fetches
+- **AUTH REQUIREMENTS:** NSE continues to use heavy browser fingerprinting, session cookies, and WAF protection
+- **NEW FEATURES:** Cannot assess
+- **RECOMMENDATION:** Verify in-production scraper logs. If bhavcopy downloads are failing, may need to rotate User-Agents or use playwright-based fetching. Consider if NSE has tightened protections further.
+- **FILE TO EDIT:** `collectors/nse_bhavcopy.py` (if issues found in production logs)
+
+---
+
+## 4. BSE
+
+- **ENDPOINT STATUS:** UP (partial — page loads but minimal content via automated fetch)
+- **STRUCTURE:** UNCHANGED (JavaScript-heavy, API-driven frontend)
+- **AUTH REQUIREMENTS:** UNCHANGED
+- **NEW FEATURES:** None detected
+- **RECOMMENDATION:** No action — BSE APIs likely still functional for the collector
+- **FILE TO EDIT:** N/A
+
+---
+
+## 5. CCIL Rates
+
+- **ENDPOINT STATUS:** CHANGED — `/web/ccil/fbil-overnight-mibor` returns **404**
+- **STRUCTURE:** MODIFIED — CCIL website restructured. New URL paths:
+  - Money market rates: `/tenor-wise-term-money`, `/repo-summary`
+  - MIBOR/TREPS: under "Data & Statistics" → "Money Market" → "Treps"
+  - Yield curve: `/zcyc-parameters`
+  - FBIL benchmarks: `/Research/FBIL%20Benchmarks/Pages/default.aspx`
+- **AUTH REQUIREMENTS:** UNCHANGED
+- **NEW FEATURES:** FBIL data also available directly at `www.fbil.org.in` (separate site)
+- **RECOMMENDATION:** **Update URL paths in collector.** Current `FBIL_URL = "https://www.fbil.org.in"` is correct for the API endpoint, but the HTML scrape fallback needs updated selectors. Test `https://www.fbil.org.in/api/ratesapi` endpoint from production.
+- **FILE TO EDIT:** `collectors/ccil_rates.py` — verify FBIL_URL API endpoint still responds; update HTML scrape fallback paths if API fails
+
+---
+
+## 6. FRED API
+
+- **ENDPOINT STATUS:** UP (returned 403 with DEMO_KEY, but real key should work)
+- **STRUCTURE:** UNCHANGED — standard JSON response format with observations array
+- **AUTH REQUIREMENTS:** UNCHANGED (API key required as before)
+- **NEW FEATURES:** None detected
+- **RECOMMENDATION:** No action. The 403 was due to using `DEMO_KEY`; real API key in env should work fine. Verify in production logs.
+- **FILE TO EDIT:** N/A
+
+---
+
+## 7. SEBI
+
+- **ENDPOINT STATUS:** UP
+- **STRUCTURE:** MODIFIED — Not using standard table format anymore. Circulars use list structure with `/legal/rules/[month-year]/[rule-title]_[ID].html` URL pattern. Has "Updated List" vs "Historical Data" toggle. Login modal overlay present.
+- **AUTH REQUIREMENTS:** Login modal overlay visible — may indicate new auth for some content
+- **NEW FEATURES:** "Historical Data" toggle functionality
+- **RECOMMENDATION:** **Investigate** — verify the collector still correctly parses the circulars listing. The URL pattern change from table to list format may need parser update.
+- **FILE TO EDIT:** `collectors/sebi_circulars.py`
+
+---
+
+## 8. data.gov.in
+
+- **ENDPOINT STATUS:** DOWN (403 Forbidden)
+- **STRUCTURE:** CANNOT VERIFY — returns 403 to automated requests
+- **AUTH REQUIREMENTS:** NEW RESTRICTIONS DETECTED — API blocking non-browser requests
+- **NEW FEATURES:** India modernizing core economic data systems (GDP rebasing to 2022-23 base year, new IIP series May 28 2026, e-SIGMA digital platform, GST/eVahan data integration)
+- **RECOMMENDATION:** **Investigate** — check if API key auth header is being sent correctly. The site may have added rate limiting or bot detection. Check `DATA_GOV_API_KEY` is valid.
+- **FILE TO EDIT:** `collectors/data_gov_in.py`
+
+---
+
+## 9. World Bank API
+
+- **ENDPOINT STATUS:** UP
+- **STRUCTURE:** UNCHANGED — returns `[metadata, data_array]` JSON. Pagination: page/pages/per_page/total. Records have indicator.id, country.id, date, value fields. India 2024 GDP: $3.91T.
+- **AUTH REQUIREMENTS:** UNCHANGED (no auth needed)
+- **NEW FEATURES:** None detected
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** N/A
+
+---
+
+## 10. IMF Data
+
+- **ENDPOINT STATUS:** CHANGED — Legacy `dataservices.imf.org` ECONNREFUSED
+- **STRUCTURE:** BROKEN for current collector — IMF has migrated to SDMX Central at `sdmxcentral.imf.org` and new API at `api.imf.org/external/sdmx/3.0`
+- **AUTH REQUIREMENTS:** New API may require account sign-in for full access
+- **NEW FEATURES:** SDMX 3.0 API available at `api.imf.org/external/sdmx/3.0`. IMF SDMX Central at `sdmxcentral.imf.org/ws/public/sdmxapi/rest/dataflow` confirmed working (BOP, DOT datasets verified present; IFS likely available).
+- **RECOMMENDATION:** **Rewrite collector** — migrate from `http://dataservices.imf.org/REST/SDMX_JSON.svc` to new `https://sdmxcentral.imf.org/ws/public/sdmxapi/rest/` endpoint. Update data parsing for SDMX 2.1 XML or new JSON format.
+- **FILE TO EDIT:** `collectors/imf_data.py` (lines 14, 24-28: BASE_URL and request logic)
+
+---
+
+## RSS FEEDS
+
+### Feed Status Summary
+
+| Feed | Status | Notes |
+|------|--------|-------|
+| reuters_business | **DEAD** | Discontinued 2020. Remove or replace. |
+| reuters_markets | **DEAD** | Discontinued 2020. Remove or replace. |
+| et_economy | UNREACHABLE | Blocked from automated fetch (likely bot protection) |
+| et_markets | UNREACHABLE | Same as above |
+| mint_economy | UNREACHABLE | Same — Mint blocks automated fetches |
+| mint_markets | UNREACHABLE | Same |
+| moneycontrol | UNREACHABLE | Blocked from this environment |
+| rbi_press | UP | Not a real RSS feed (HTML page). Listed URL is the press releases page, not an RSS endpoint. Collector handles this via HTML scraping. |
+| fed_press | **UP** | RSS 2.0, items have title/link/description/pubDate/guid/category. Latest: May 22, 2026. Working perfectly. |
+| ecb_press | **UP** | RSS 2.0, items have title/link/guid/pubDate. Latest build: May 22, 2026. Working. |
+| coindesk | **UP** | RSS 2.0 with media/dc/content namespaces. Latest: May 24-25, 2026. TTL 5min. Working. |
+| cnbc | **UP** | RSS 2.0, 27 items, metadata:type tags present. Last built May 24, 2026. Working. |
+| ft_markets | UNREACHABLE | FT likely paywalled/blocked |
+| arxiv_qfin | **UP** | RSS 2.0, lastBuildDate May 24, 2026. Feed structure intact but items may be empty on weekends. |
+
+### RSS Recommendations
+
+- **CRITICAL:** Remove `reuters_business` and `reuters_markets` from `config/sources.yaml` or replace with alternatives:
+  - Google News RSS: `https://news.google.com/rss/search?q=when:24h+allinurl:reuters.com`
+  - Or use RSS.app/Feedspot generated feeds
+- **INVESTIGATE:** Indian news feeds (ET, Mint, MoneyControl) — verify they work from production server (may be blocked only from non-Indian IPs)
+- **FILE TO EDIT:** `config/sources.yaml` (feeds section)
+
+---
+
+## SOCIAL SCRAPERS
+
+### 11. Reddit
+
+- **STATUS:** FUNCTIONAL (with caveats)
+- **CHANGES:** Reddit API pricing tiers still in effect (since 2023): Free tier = 100 req/min with OAuth, 10K monthly calls. Commercial = $12K/year. The scraper uses `.json` endpoint which is still free for read-only.
+- **RISK:** Reddit has increasingly enforced rate limits on unauthorized scraping. The `.json` endpoint may get restricted.
+- **RECOMMENDATION:** Monitor rate limit errors in production. Consider if OAuth credentials are being used. The free tier (100 req/min, 10K/month) should suffice for current monitoring volume.
+- **FILE TO EDIT:** `scrapers/reddit_scraper.py` (no changes needed now)
+
+### 12. Hacker News
+
+- **STATUS:** UP — Firebase API working perfectly
+- **STRUCTURE:** UNCHANGED — returns JSON array of integer story IDs. `https://hacker-news.firebaseio.com/v0/topstories.json` confirmed operational.
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** N/A
+
+### 13. YouTube
+
+- **STATUS:** UP (quota system unchanged)
+- **CHANGES:** Default 10,000 units/day quota still in effect. Search costs 100 units each. Stricter compliance audits for high-volume usage.
+- **RISK:** 10 search queries × 100 units = 1,000 units/run. At medium frequency, quota should be fine.
+- **RECOMMENDATION:** No action — monitor quota usage
+- **FILE TO EDIT:** N/A
+
+### 14. Mastodon
+
+- **STATUS:** UP — Public timeline API requires no auth
+- **STRUCTURE:** UNCHANGED — instances listed (mastodon.social, fosstodon.org, etc.) still support public API
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** N/A
+
+### 15. GitHub
+
+- **STATUS:** UP
+- **STRUCTURE:** REST API v3 unchanged. Rate limits: 5000 req/hour with token, 60/hour without.
+- **RECOMMENDATION:** No action — ensure `GITHUB_TOKEN` env var is set
+- **FILE TO EDIT:** N/A
+
+### 16. SEC EDGAR
+
+- **STATUS:** CHANGED — EFTS endpoint returning 403
+- **STRUCTURE:** MODIFIED — EDGAR Next initiative rolled out. New API requires enrollment. EDGAR Release 26.0.1 deployed Feb 2026.
+- **AUTH REQUIREMENTS:** NEW — EDGAR Next requires individual user credentials + MFA for submission API. Read access may now require proper User-Agent with contact email.
+- **NEW FEATURES:** EDGAR Next APIs (submission, account management, role-based access)
+- **RECOMMENDATION:** **Update User-Agent header** in `sec_scraper.py`. Current: `"SocialScraper research@example.com"` — update the email to a real contact email. SEC requires: `Company Name AdminEmail@company.com`. Also verify EFTS URL hasn't changed to a new path under EDGAR Next.
+- **FILE TO EDIT:** `scrapers/sec_scraper.py` (line 62: User-Agent header, lines 52-54: EFTS_URL)
+
+### 17. Discord
+
+- **STATUS:** UP — API v10 still current
+- **STRUCTURE:** UNCHANGED
+- **RECOMMENDATION:** No action — verify `DISCORD_BOT_TOKEN` has MESSAGE_CONTENT intent
+- **FILE TO EDIT:** N/A
+
+### 18. Dark Web
+
+- **STATUS:** Cannot verify (Tor proxy not available from this environment)
+- **RECOMMENDATION:** Verify tor container is running and SOCKS5 proxy at port 9050 is accessible from worker container
+- **FILE TO EDIT:** N/A
+
+### 19. Web Scraper
+
+- **STATUS:** Site-dependent
+- **RECOMMENDATION:** No action — general purpose scraper adapts to targets
+- **FILE TO EDIT:** N/A
+
+### 20. Central Banks
+
+- **STATUS:** MIXED
+  - Fed press RSS: UP (confirmed working, latest May 22, 2026)
+  - ECB press RSS: UP (confirmed working, latest May 22, 2026)
+  - RBI press: UP (HTML page, not RSS — collector handles via scraping)
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** N/A
+
+---
+
+## MESSAGING
+
+### 21. Telegram
+
+- **STATUS:** UP (API access depends on credentials)
+- **CHANGES:** No known API changes. Telegram Bot API stable.
+- **RECOMMENDATION:** Verify `TELEGRAM_API_ID` and `TELEGRAM_API_HASH` are current. Check channel access.
+- **FILE TO EDIT:** N/A
+
+### 22. Twitter/X
+
+- **STATUS:** HIGH RISK
+- **CHANGES (CRITICAL):**
+  - X introduced "Pay-Per-Use" billing Feb 2026
+  - Free tier is WRITE-ONLY (cannot read/scrape)
+  - Basic tier: $200/mo for 10K tweets read
+  - Cloudflare Turnstile deployed on login walls and rate-limited endpoints
+  - Jan 2025: Guest token bound to browser fingerprints; datacenter IPs banned
+  - Legal threat: $15K liquidated damages for >1M posts/24h automated access
+- **AUTH REQUIREMENTS:** Cookie-based scraping via `twikit` is HIGH RISK — X actively detects and bans
+- **RECOMMENDATION:** **HIGH PRIORITY** — Current `twikit` cookie approach is likely broken or at serious risk. Options:
+  1. Pay for Basic tier ($200/mo) for legitimate read access
+  2. Use a third-party scraping API service (various providers available)
+  3. Reduce scraping frequency significantly
+  4. Accept that Twitter data may be intermittent
+- **FILE TO EDIT:** `scrapers/twitter_scraper.py`, `collectors/twitter_lists.py`
+
+---
+
+## CONNECTORS
+
+### 23. DragonScope Connector
+- **STATUS:** UP (depends on Redis and API endpoint)
+- **RECOMMENDATION:** Verify `DRAGONSCOPE_REDIS_URL` and `DRAGONSCOPE_API_URL` connectivity
+- **FILE TO EDIT:** N/A
+
+### 24. LiquiFi Connector
+- **STATUS:** UP (depends on Redis and API endpoint)
+- **RECOMMENDATION:** Verify `LIQUIFI_REDIS_URL` and `LIQUIFI_API_URL` connectivity
+- **FILE TO EDIT:** N/A
+
+### 25. Router
+- **STATUS:** UP — classification logic solid
+- **STRUCTURE:** Platform-based routing with content-override. Coverage:
+  - DragonScope: Reddit, Discord, YouTube, HackerNews, Mastodon, GitHub
+  - LiquiFi: Central Bank data
+  - Both: Twitter, Telegram, RSS, Web, SEC EDGAR, Dark Web
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** N/A
+
+---
+
+## INFRASTRUCTURE
+
+### 26. Celery Beat Schedules
+
+- **STATUS:** CONSISTENT
+- `scheduler/schedule.py` — correctly marked as deprecated (reference only)
+- `core/scheduler.py` — builds beat schedule dynamically from `config/sources.yaml`
+- All sources in `config/sources.yaml` have matching collector files in `collectors/`
+- All scrapers have corresponding files in `scrapers/`
+- **No orphaned schedule entries detected**
+- **RECOMMENDATION:** No action
+
+### 27. Docker Compose
+
+- **STATUS:** OK
+- Services defined: postgres, redis, minio, zookeeper, kafka, tor, api, worker (+ beat implied)
+- Ports: 5432, 6379, 9000/9001, 2181, 9092, 9050/8118, 8000 — no conflicts
+- Health checks: postgres (pg_isready), redis (ping), minio (mc ready), kafka (topics --list), api (curl /health)
+- **Note:** `dperson/torproxy` image — verify it's still maintained (last DockerHub update should be checked)
+- **RECOMMENDATION:** No action needed for port conflicts or health checks
+

+1. **Update RBI DBIE URL** → `data.rbi.org.in/DBIE/`
+   - File: `collectors/rbi_dbie.py` line 24, `config/sources.yaml`
+   
+2. **Fix/Verify CCIL rates** — test FBIL API endpoint from production
+   - File: `collectors/ccil_rates.py`
+
+3. **Remove dead Reuters feeds** from `config/sources.yaml`
+   - Replace with Google News RSS alternatives or remove entirely
+
+### P1 — High Priority (Next Sprint)
+
+4. **Rewrite IMF collector** for SDMX Central API
+   - File: `collectors/imf_data.py` — migrate to `sdmxcentral.imf.org`
+
+5. **Update SEC EDGAR User-Agent** with real contact email
+   - File: `scrapers/sec_scraper.py` line 62
+
+6. **Assess Twitter/X scraping viability** — decide on paid API vs third-party service vs accept degraded data
+   - Files: `scrapers/twitter_scraper.py`, `collectors/twitter_lists.py`
+
+### P2 — Medium Priority (Next 2 Weeks)
+
+7. **Verify SEBI collector** still parses new list-based layout
+   - File: `collectors/sebi_circulars.py`
+
+8. **Check data.gov.in API** from production (may be geo-restricted)
+   - File: `collectors/data_gov_in.py`
+
+9. **Evaluate new sources:** FBIL direct, API Setu, FinEdge API for NBFC treasury data enrichment
+
+---
+
+## ENVIRONMENT NOTES
+
+- Some endpoints (ET, Mint, MoneyControl, NSE, FT) are unreachable from this validation environment but may work from the production server (different IP/geo/headers). Check production collector logs for ground truth.
+- SEC EDGAR's 403 responses may be specific to this environment's IP/User-Agent. Production should be verified separately.
+- IMF legacy API connection refused is definitive — the service has been decommissioned.

+# Weekly Deep Source Validation Report
+**Date:** 2026-04-13 (Sunday)
+**System:** social_scraper (econscraper)
+
+---
+
+## EXECUTIVE SUMMARY
+
+**25 sources checked | 7 BROKEN | 6 DEGRADED | 12 HEALTHY**
+
+### URGENT: Regulatory & Compliance Changes
+- **NSE Static IP Mandate (April 1, 2026)** - All algo trading API keys without static IP binding have expired. Any automated data collection connected to NSE needs static IP compliance verification immediately.
+- **RBI Data Protection Advisory (April 2026)** - New advisory directing all regulated entities (including NBFCs) to prioritize customer data protection and API security. Mandatory compliance.
+- **RBI Digital Payment Authentication Framework (April 1, 2026)** - Risk-based authentication replacing SMS OTP-only approaches. Affects payment processing.
+- **X/Twitter API now pay-per-use** - No free tier for new developers. $0.005/post read, $0.010/user profile. Budget impact for sentiment scraping.
+
+### Critical Issues Requiring Immediate Action
+1. **Reuters RSS feeds** - DEAD — `feeds.reuters.com` DNS no longer resolves. Replace URLs.
+2. **FBIL/CCIL rates** - `fbil.org.in` returning ECONNREFUSED. Migrate to `ccilindia.com`. Critical for LiquiFi.
+3. **Mastodon public timeline** - Now returns 422 without auth. Scraper needs token.
+4. **RBI DBIE** - TLS cert broken on `dbie.rbi.org.in`. Portal migrated to `data.rbi.org.in` (SPA).
+5. **data.gov.in** - All endpoints returning 403/404. API may be retired or migrated.
+6. **IMF SDMX API** - `dataservices.imf.org` completely unreachable (TCP timeout). Portal rebuilt as Next.js app. API likely decommissioned.
+7. **Moneycontrol RSS** - Feed FROZEN since April 2024. Serving stale cached data. Find new URL.
+
+### Warnings (Degraded but Functional)
+7. **SEC EDGAR EFTS** - 403 without proper User-Agent. Scraper has placeholder email.
+8. **World Bank API** - Intermittent timeouts (slow/overloaded).
+9. **ET Economy + ECB Press RSS** - Missing `<description>` tags in items. Parser needs fallback.
+10. **RBI Press RSS** - Configured URL is HTML page, not RSS feed. Needs HTML scraper or new URL.
+11. **arXiv q-fin RSS** - Empty on weekends by design (academic publishing schedule, not a bug).

+
+## STRUCTURED DATA COLLECTORS
+
+### 1. RBI DBIE (collectors/rbi_dbie.py)
+- **ENDPOINT STATUS:** **DEGRADED** - `dbie.rbi.org.in` has **TLS certificate mismatch** (ERR_TLS_CERT_ALTNAME_INVALID). Portal appears to have migrated to `data.rbi.org.in`.
+- **STRUCTURE:** **CHANGED** - New URL `data.rbi.org.in` is a heavy SPA (MapMyIndia API, Material Design) — no server-side data, requires headless browser (Playwright/Puppeteer) or discovery of underlying API endpoints.
+- **AUTH REQUIREMENTS:** UNCHANGED - No login wall, but SPA architecture blocks simple HTTP scraping.
+- **RECOMMENDATION:** Update BASE_URL to `data.rbi.org.in`. Fallback scraping of `PublicationsView.aspx` on `rbi.org.in` still works and is the most reliable path. Investigate `data.rbi.org.in` XHR endpoints for direct API access.
+- **FILE TO EDIT:** collectors/rbi_dbie.py (update BASE_URL; optionally add headless browser support)
+
+### 2. RBI Circulars (collectors/rbi_circulars.py)
+- **ENDPOINT STATUS:** UP - rbi.org.in accessible
+- **STRUCTURE:** UNCHANGED - Press releases, notifications, circulars pages accessible
+- **AUTH REQUIREMENTS:** UNCHANGED
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** None
+
+### 3. NSE Bhavcopy (collectors/nse_bhavcopy.py)
+- **ENDPOINT STATUS:** UP (with anti-bot measures)
+- **STRUCTURE:** UNCHANGED - API endpoints respond after cookie prefetch
+- **AUTH REQUIREMENTS:** UNCHANGED - Session cookies from homepage required
+- **NEW FEATURES:** None detected
+- **⚠️ NSE STATIC IP MANDATE (April 1, 2026):** All algo trading API keys without static IP binding have expired. IPv4 only (no IPv6), max 2 IPs (primary+secondary), must be registered with broker. Verify data collection server IPs are compliant.
+- **RECOMMENDATION:** **VERIFY** static IP compliance for production server. Cookie prefetch pattern still works for data scraping, but any order/algo API integration is affected.
+- **FILE TO EDIT:** collectors/nse_bhavcopy.py (verify; may need config for static IP)
+
+### 4. BSE API (collectors/bse_api.py)
+- **ENDPOINT STATUS:** SLOW - api.bseindia.com times out intermittently
+- **STRUCTURE:** UNCHANGED - API endpoint patterns unchanged
+- **AUTH REQUIREMENTS:** UNCHANGED - Referer header still required
+- **RECOMMENDATION:** Consider adding retry with backoff for timeout resilience
+- **FILE TO EDIT:** collectors/bse_api.py (optional improvement)
+
+### 5. CCIL/FBIL Rates (collectors/ccil_rates.py)
+- **ENDPOINT STATUS:** **SPLIT** - `ccilindia.com` is UP (ZCYC rates, MIBOR-OIS, bond/forex/derivatives data under Data & Statistics). `fbil.org.in` is **DOWN** (ECONNREFUSED confirmed). FBIL sub-pages on CCIL also timed out.
+- **STRUCTURE:** CCIL has yield curve data, MIBOR data, government securities, forex data accessible from its Data & Statistics section. FBIL reference rates (MIBOR benchmarks, TREPS) are NOT directly on CCIL homepage — FBIL is a separate entity whose domain is down.
+- **AUTH REQUIREMENTS:** CCIL public content accessible without auth. Sign-in exists for member portal.
+- **RECOMMENDATION:** **MIGRATE** collector to source MIBOR/ZCYC data from `ccilindia.com/web/ccil/` Data & Statistics pages instead of `fbil.org.in`. Critical for LiquiFi connector (MIBOR, TREPS, yield curve, CP/CD rates).
+- **FILE TO EDIT:** collectors/ccil_rates.py (replace FBIL_URL with CCIL data pages; add CCIL ZCYC endpoint)
+
+### 6. FRED API (collectors/fred_api.py)
+- **ENDPOINT STATUS:** UP - API responds correctly with valid API key
+- **STRUCTURE:** UNCHANGED - JSON response format stable
+- **AUTH REQUIREMENTS:** UNCHANGED - API key required (DEMO_KEY returns 403 as expected)
+- **NEW FEATURES:** **FRED API v2 (Nov 2025)** - Bulk retrieval of observations for all series in any release with full history in JSON/XML. ALFRED archival content no longer saveable (Jan 5, 2026).
+- **RECOMMENDATION:** **UPGRADE** to FRED API v2 bulk retrieval for efficient macro data pulls (FEDFUNDS, DGS10, SOFR, etc.). Significant efficiency gain for treasury analysis.
+- **FILE TO EDIT:** collectors/fred_api.py (add v2 bulk retrieval endpoint support)
+
+### 7. SEBI Circulars (collectors/sebi_circulars.py)
+- **ENDPOINT STATUS:** UP (partially) - Homepage and Enforcement section load. **Circulars-specific listing page times out repeatedly.**
+- **STRUCTURE:** UNCHANGED - URL pattern `HomeAction.do?doListing=yes&sid=[section]&ssid=[subsection]`. Confirmed: sid=1 (Legal Framework), sid=2 (Enforcement, 54K+ records, 25/page pagination). Legal document pattern: `/legal/[type]/[month-year]/[title]_[id].html`.
+- **AUTH REQUIREMENTS:** UNCHANGED - Public documents accessible. SI Portal requires login.
+- **RECOMMENDATION:** Increase HTTP timeout to 90s+. Add retry logic specifically for circulars listing. Consider scraping from the Legal Framework section (sid=1) as an alternative path.
+- **FILE TO EDIT:** collectors/sebi_circulars.py (timeout 90s, retry logic)
+
+### 8. data.gov.in (collectors/data_gov_in.py)
+- **ENDPOINT STATUS:** **DOWN/BLOCKED** - All endpoints returning 403 Forbidden or 404. Main domain, catalog page, search page, and API subdomain (`api.data.gov.in`) all reject non-browser requests.
+- **STRUCTURE:** UNKNOWN - Cannot verify; API subdomain returns 404 suggesting possible API restructuring or retirement.
+- **AUTH REQUIREMENTS:** Cannot be determined. Historically required API key registration.
+- **RECOMMENDATION:** **INVESTIGATE URGENTLY** - Test from server with browser-like headers. If still blocked, check if API has been restructured under new endpoints (e.g., `apisetu.gov.in`). May need to deprioritize or mark as broken.
+- **FILE TO EDIT:** collectors/data_gov_in.py (headers + possible URL migration)
+
+### 9. World Bank API (collectors/world_bank.py)
+- **ENDPOINT STATUS:** DEGRADED - Intermittent timeouts (60s+)
+- **STRUCTURE:** UNCHANGED when accessible - JSON format with paginated arrays
+- **AUTH REQUIREMENTS:** UNCHANGED - No auth needed
+- **RECOMMENDATION:** Increase timeout to 90s; add retry with exponential backoff
+- **FILE TO EDIT:** collectors/world_bank.py (timeout/retry improvement)
+
+### 10. IMF Data (collectors/imf_data.py)
+- **ENDPOINT STATUS:** **DOWN** - `dataservices.imf.org` SDMX REST API is unreachable. DNS resolves (134.113.242.23) but TCP connection times out on port 443. Tested with 10s, 15s, 60s, 90s timeouts — all fail. Dataflow endpoint also dead.
+- **STRUCTURE:** CANNOT VERIFY - No response received from any endpoint.
+- **AUTH REQUIREMENTS:** Historically none. Cannot verify current state.
+- **PORTAL:** `data.imf.org` is accessible (HTTP 200) but has been rebuilt as a **Next.js application** — suggesting platform migration. Old SDMX API may be decommissioned.
+- **NOTE:** Collector uses HTTP (not HTTPS) for a now-dead endpoint — both issues need fixing.
+- **RECOMMENDATION:** **INVESTIGATE NEW IMF API** - The old `dataservices.imf.org/REST/SDMX_JSON.svc/` path appears decommissioned. Check IMF developer docs for replacement API (likely under `data.imf.org` or new SDMX endpoint). This is a **breaking change**.
+- **FILE TO EDIT:** collectors/imf_data.py (new BASE_URL needed — old endpoint is dead)

+
+## RSS FEEDS (collectors/rss_feeds.py)
+
+| # | Feed | Status | Items | Structure | Issue |
+|---|------|--------|-------|-----------|-------|
+| 1 | reuters_business | **BROKEN** | 0 | DNS dead | `feeds.reuters.com` no longer resolves. Dead since 2020. |
+| 2 | reuters_markets | **BROKEN** | 0 | DNS dead | Same — entire domain is defunct |
+| 3 | et_economy | UP | 49 | title, link, guid, pubDate | **Missing `<description>`** in items (only channel-level) |
+| 4 | et_markets | UP | 50 | title, description, link, enclosure, guid, pubDate | Full structure with images |
+| 5 | mint_economy | UP | 35 | title, description, link, guid, pubDate, media:content | Healthy (CDATA wrapping) |
+| 6 | mint_markets | UP | 35 | title, description, link, guid, pubDate, media:content | Healthy |
+| 7 | moneycontrol | **STALE** | 15 | title, description, link, guid, pubDate | **FROZEN since April 2024.** lastBuildDate=Aug 2024. ISO-8859-1 encoding. |
+| 8 | rbi_press | **WARNING** | N/A | **HTML, not RSS** | ASPX page, not a feed. `/Scripts/rss.aspx` also HTML. Needs HTML scraper. |
+| 9 | fed_press | UP | 20 | title, link, guid, description, category, pubDate | Excellent — includes `<category>` tags |
+| 10 | ecb_press | UP | 15 | title, link, guid, pubDate | **Missing `<description>`** in items. Some links to PDFs. Double-slash URLs. |
+| 11 | coindesk | UP | 25 | title, description, link, guid, pubDate, media:content, dc:creator, content:encoded | Healthy — rich feed, TTL=5min. (403 only from some tools) |
+| 12 | cnbc | UP | 25 | title, description, link, guid, pubDate + custom metadata namespace | Healthy — TTL=60min |
+| 13 | ft_markets | UP | 25 | title, description, link, guid, pubDate | Healthy — redirects to stream URL. TTL=15min. |
+| 14 | arxiv_qfin | UP | 15 | title, description (abstract), link, guid, category, dc:creator, arxiv:announce_type | Healthy — **empty on weekends by design** (academic publishing schedule) |
+
+### RSS Feed Actions Required:
+- **REPLACE** reuters_business and reuters_markets URLs — domain `feeds.reuters.com` is completely dead (DNS failure)
+- **FIX** moneycontrol feed — frozen since April 2024, serving stale cached data. Find new RSS URL or switch to web scraping.
+- **FIX** rbi_press URL — this is an HTML page, not RSS. Switch to HTML scraper or find actual RSS endpoint.
+- **HANDLE** et_economy and ecb_press missing `<description>` gracefully in parser (use title as fallback)
+- **NOTE** coindesk is actually healthy (25 items) — earlier 403 was tool-specific, not a real block
+- **NOTE** arxiv_qfin is empty on weekends by design, not intermittent
+
+**FILE TO EDIT:** config/sources.yaml (Reuters URLs, moneycontrol URL), collectors/rss_feeds.py (description fallback for et_economy/ecb_press, rbi_press HTML handling)
+
+---
+
+## SOCIAL SCRAPERS
+
+### 11. Reddit (scrapers/reddit_scraper.py)
+- **ENDPOINT STATUS:** UP - .json endpoint works from servers (blocked by some CDN tools)
+- **STRUCTURE:** UNCHANGED - data.children array with post objects
+- **AUTH REQUIREMENTS:** UNCHANGED for .json endpoint. **Official API pricing:** Standard tier $12K/year (100 req/min), Enterprise $50K-$500K+. r/all is being deprecated (Reddit shifting to algorithmic discovery).
+- **RECOMMENDATION:** Continue using .json endpoint (free, no API key). Monitor for any restrictions on unauthenticated access. Note r/all deprecation may affect subreddit discovery.
+- **FILE TO EDIT:** None (monitor only)
+
+### 12. Hacker News (scrapers/hackernews_scraper.py)
+- **ENDPOINT STATUS:** UP - Firebase API fully functional
+- **STRUCTURE:** UNCHANGED - topstories.json returns 500 IDs, newstories works
+- **AUTH REQUIREMENTS:** UNCHANGED - No auth needed
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** None
+
+### 13. YouTube (scrapers/youtube_scraper.py)
+- **ENDPOINT STATUS:** UP - Data API v3 responds (auth error without key = expected)
+- **STRUCTURE:** UNCHANGED
+- **AUTH REQUIREMENTS:** UNCHANGED - API key required, quota applies
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** None
+
+### 14. Mastodon (scrapers/mastodon_scraper.py)
+- **ENDPOINT STATUS:** **BROKEN** - `/api/v1/timelines/public` returns 422 "Unprocessable Entity"
+- **STRUCTURE:** CHANGED - mastodon.social now requires authentication for public timeline
+- **AUTH REQUIREMENTS:** **NEW RESTRICTION** - Authentication token now required for `/timelines/public`
+- **WORKAROUND AVAILABLE:** `/api/v1/trends/statuses` works WITHOUT auth (HTTP 200). Returns trending statuses with full structure (id, content, account, stats, quotes). Instance is v4.6.0-nightly with 3.2M users.
+- **RECOMMENDATION:** **QUICK FIX:** Switch to `/api/v1/trends/statuses` endpoint (no auth needed, returns trending content). **FULL FIX:** Add OAuth token support for `/timelines/public` access. Can use both: trends for immediate data, public timeline for comprehensive coverage with auth.
+- **FILE TO EDIT:** scrapers/mastodon_scraper.py (switch default endpoint to trends/statuses; add optional OAuth token for public timeline)
+
+### 15. GitHub (scrapers/github_scraper.py)
+- **ENDPOINT STATUS:** UP - API working, 60 req/hr unauthenticated
+- **STRUCTURE:** UNCHANGED
+- **AUTH REQUIREMENTS:** UNCHANGED - Token optional but recommended for higher limits
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** None
+
+### 16. SEC EDGAR (scrapers/sec_scraper.py)
+- **ENDPOINT STATUS:** **DEGRADED** - EFTS returns 403 without proper User-Agent
+- **STRUCTURE:** UNCHANGED - But new `data.sec.gov` REST API available alongside EFTS
+- **AUTH REQUIREMENTS:** **STRICTER** - SEC now enforces User-Agent header with real email
+- **NEW FEATURES:** EDGAR Release 26.1 (March 2026) added operational status indicators for degraded service. EDGAR Release 26.0.1 (Feb 2026) updated submission notifications. `data.sec.gov` REST APIs remain free, keyless, JSON — only need User-Agent.
+- **RECOMMENDATION:** **UPDATE User-Agent** - Replace `research@example.com` with a real email. Consider adding `data.sec.gov` as supplementary source.
+- **FILE TO EDIT:** scrapers/sec_scraper.py (line 61: update User-Agent email)
+
+### 17. Discord (scrapers/discord_scraper.py)
+- **ENDPOINT STATUS:** UP - API v10 is current
+- **STRUCTURE:** MINOR CHANGES - PIN_MESSAGES split from MANAGE_MESSAGES (Feb 23, 2026). DAVE E2E encryption mandatory for voice/video (March 1, 2026).
+- **AUTH REQUIREMENTS:** UNCHANGED - Bot token + MESSAGE_CONTENT intent required. Check if bot permissions need updating for PIN_MESSAGES split.
+- **RECOMMENDATION:** Verify bot permissions after PIN_MESSAGES/MANAGE_MESSAGES split. Voice/video not relevant for text scraping.
+- **FILE TO EDIT:** scrapers/discord_scraper.py (check permission flags if using pinning)
+
+### 18. Dark Web (scrapers/darkweb_scraper.py)
+- **ENDPOINT STATUS:** DEPENDS ON TOR - Cannot verify externally (needs SOCKS5 proxy)
+- **STRUCTURE:** N/A - Varies by .onion site
+- **AUTH REQUIREMENTS:** UNCHANGED - Tor proxy required
+- **RECOMMENDATION:** Test from Docker container with Tor proxy running
+- **FILE TO EDIT:** None
+
+### 19. Web Scraper (scrapers/web_scraper.py)
+- **ENDPOINT STATUS:** UP - General web targets accessible
+- **STRUCTURE:** UNCHANGED
+- **AUTH REQUIREMENTS:** UNCHANGED
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** None
+
+### 20. Central Banks (scrapers/centralbank_scraper.py)
+- **ENDPOINT STATUS:** UP - Fed RSS confirmed working, RBI pages accessible
+- **STRUCTURE:** UNCHANGED - Standard RSS/HTML scraping
+- **AUTH REQUIREMENTS:** UNCHANGED
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** None
+
+---
+
+## MESSAGING
+
+### 21. Telegram (collectors/telegram_channels.py)
+- **ENDPOINT STATUS:** REQUIRES CREDENTIALS - Cannot verify without api_id/api_hash
+- **STRUCTURE:** N/A
+- **AUTH REQUIREMENTS:** UNCHANGED - Telethon/Pyrogram with API credentials
+- **RECOMMENDATION:** Verify from running instance
+- **FILE TO EDIT:** None
+
+### 22. Twitter/X (collectors/twitter_lists.py)
+- **ENDPOINT STATUS:** UNCERTAIN - Cookie-based scraping fragile; X continues tightening
+- **STRUCTURE:** LIKELY CHANGED - X regularly changes page structure
+- **AUTH REQUIREMENTS:** **MAJOR CHANGE** - X shifted to pay-per-use model (Feb 6, 2026). No free tier for new developers. Reading a post: $0.005, user profile: $0.010, creating post: $0.010. 24h deduplication window. 2M post-read/month cap before Enterprise required. Legacy free tier users get $10 voucher then move to pay-as-you-go.
+- **COST ESTIMATE:** At 10K posts/day = ~$1,500/month. Consider cost-benefit for sentiment scraping.
+- **RECOMMENDATION:** **EVALUATE BUDGET** - Cookie scraping remains the free path but is fragile. If moving to official API, budget for pay-per-use costs. Consider reducing scrape frequency or filtering to treasury-relevant content only.
+- **FILE TO EDIT:** collectors/twitter_lists.py (verify cookie auth; if migrating to API, add billing config)
+
+---
+
+## CONNECTORS
+
+### 23. DragonScope Connector (connectors/dragonscope.py)
+- **CODE STATUS:** HEALTHY
+- **STRUCTURE:** Well-architected with Redis primary + API fallback
+- **CATEGORIES:** reddit_posts, news, github_repos, sec_filings all mapped
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** None
+
+### 24. LiquiFi Connector (connectors/liquifi.py)
+- **CODE STATUS:** HEALTHY
+- **STRUCTURE:** Good treasury keyword scoring with boundary-matching for short keywords
+- **RATE PATTERNS:** Properly validates ranges (repo 0-15%, MIBOR 0-20%, USDINR 40-150)
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** None
+
+### 25. Router (connectors/router.py)
+- **CODE STATUS:** HEALTHY
+- **LOGIC:** Platform-based routing with treasury-score content override
+- **CATEGORIES COVERED:** All 13 platforms mapped to DRAGONSCOPE/LIQUIFI/BOTH
+- **RECOMMENDATION:** No action
+- **FILE TO EDIT:** None
+
+---
+
+## INFRASTRUCTURE
+
+### 26. Celery Beat Schedules
+- **scheduler/schedule.py** - DEPRECATED (correctly marked, imports are no-op)
+- **core/scheduler.py** - CANONICAL source, dynamically builds from sources.yaml
+- **config/sources.yaml** - 15 YAML-driven collectors defined
+- **Social scraper schedules** - 13 additional hard-coded in core/scheduler.py

+**No missing schedules.** All scrapers/collectors have schedule entries.
+
+### 27. Docker Compose
+- **Services:** 10 defined (postgres, redis, minio, zookeeper, kafka, tor, api, worker, beat, nlp-worker, flower)
+- **Port conflicts:** NONE - All ports unique (5432, 6379, 9000, 9001, 2181, 9092, 9050, 8118, 8000, 5555)
+- **Health checks:** postgres, redis, minio, kafka, api all have health checks
+- **Missing health checks:** tor (restart: unless-stopped only), beat, nlp-worker, flower
+- **RECOMMENDATION:** Add health checks for beat and nlp-worker services
+- **FILE TO EDIT:** docker-compose.yml (optional - add health checks)
