FASE 1 — market_family_key() general election fix
General elections now group by office, not by party, so complementary
markets ("Republicans win Ohio governor" / "Democrats win Ohio governor")
share the same family key (ohio-gubernatorial-2026). The second market
is blocked by the occupied_families check rather than traded as independent.
Primaries still keep the party (texas-republican-2026) because each party
runs its own separate primary race.
FASE 2 — Manifold party inversion guard
_detect_party() identifies the winning side in both the Polymarket question
and the matched Manifold title. If they are confirmed opposites (republican
vs democrat), the probability is inverted (1 - prob) before use.
Full audit log per query:
poly_question / manifold_title / manifold_url / match_score /
prob_raw / inverted / prob_final
Root cause of Ohio Manifold:0.95 on both sides: both queries matched the
same Manifold market ("Republicans win Ohio governor" prob=0.95). For the
"Democrats win" query the inversion now produces prob_final=0.05 instead of
blindly applying 0.95 to the wrong direction.
FASE 4 — startup contradiction scan
get_open_position_details() added to db.py. main.py checks all open
positions at startup, warns on any family with >1 position, and recommends
keeping the one with the highest edge_net. No auto-close.

Signal 5: ManifoldClient queries Manifold Markets API for a matching binary
market by keyword overlap (threshold 0.25) and applies a log-odds adjustment
proportional to the divergence from the Polymarket prior.
manifold_log_adj = (log_odds(manifold_prob) - log_odds(prior)) × 0.6
A 30pp divergence (Manifold 0.75 vs Poly 0.45) produces edge_gross ≈ 0.19,
clearing the politics far-horizon regime_min=0.12 after costs. Confidence
boosted +0.08 when Manifold match found.
Per-feature observability: every SKIP_EDGE_NET and TRADE log line now includes
fg=±X.XXX mom=±X.XXX mfld=±X.XXXX news=±X.XXXX
so the contribution of each signal to edge is auditable per market.

Phase 1 — Edge neto real (paper.py, bayesian.py, risk/manager.py, db.py):
- Trade records now store edge_gross, edge_net, prior_prob, final_prob,
mid_price, spread_estimate, commission, family_key
- edge_net = edge_gross - SPREAD_ESTIMATE(0.02) - COMMISSION_RATE(0.02)
NOTE: both constants are heuristics, not exact Polymarket exchange costs
- Execution gate changed from edge_gross > MIN_EDGE to edge_net > regime_min_edge
Phase 2 — Market families (polymarket.py):
- market_family_key(market) groups related markets:
texas-republican-2026, fed-april-2026, openai-2026, etc.
- At most 1 trade per family per cycle; occupied_families propagated via main.py
- Family key logged on every TRADE and SKIP line
Phase 3 — GNews priority (news.py, bayesian.py, main.py):
- NewsClient.get_freshness() returns 1.0/0.75/0.40/0.10 by cache age
- gnews_priority(market, news) = uncertainty × volume_score × freshness
- Politics markets sorted by priority DESC before eval so best markets get
the 5-query/cycle GNews budget first
Phase 4 — Regime min-edge by category/horizon (bayesian.py):
- politics >60d → 0.12, 30-60d → 0.10, <30d → 0.08
- tech / crypto/finance → 0.10
- All thresholds applied to edge_net (not edge_gross)
Phase 5 — Observability (bayesian.py, main.py):
- Structured skip labels: SKIP_UNSUPPORTED, SKIP_NO_SIGNALS,
SKIP_PRIOR_EXTREME, SKIP_FAMILY, SKIP_GNEWS_PRIORITY, SKIP_EDGE_NET
- TRADE lines now include family_key, edge_gross, edge_net, regime_min, days
- schema.sql: 8 new cols on trades, 7 new cols on signals (via ALTER TABLE IF NOT EXISTS)

- Add European football leagues (La Liga, Premier League, Bundesliga, etc.)
to _SPORTS_EXCLUSIONS so those markets are filtered before category detection
- Reorder _detect_category: check tech before crypto/finance so company-specific
markets (OpenAI IPO, NVIDIA, Apple) resolve to "tech" instead of "crypto/finance"
- Widen resolution horizon default from 60 to 90 days to surface more
markets in the 0.08–0.92 uncertainty zone

- Reconstruct dashboard from compiled container: App.jsx, main.jsx, index.css
- nginx.conf with SPA routing and /api proxy to api:8000
- Multi-stage Dockerfile: node:20-alpine build + nginx:alpine serve
- Add third kaniko build step in ci.yml for chemavx/polymarket-bot-dashboard
- Update k8s manifest sed to patch deployment-dashboard.yaml image on each push

Add _SPORTS_EXCLUSIONS list checked first in _detect_category so NBA/NFL/
MLB/NHL/tennis/golf/UFC/boxing/wrestling/tournament markets never bleed into
politics or events categories. Also removes 'super bowl' from _EVENTS_KEYWORDS
since it's now covered by the sports exclusion.
Keywords excluded: nba, nfl, mlb, nhl, basketball, football, baseball, hockey,
soccer, mvp, rookie of the, championship, super bowl, world series, playoffs,
playoff, tournament, tennis, golf, ufc, boxing, wrestler, wrestling,
slam dunk, home run, touchdown.

Markets where Polymarket consensus is near-certain leave no room for our
signals to generate MIN_EDGE=0.10 — evaluating them wastes GNews quota and
produces noise. Filter them out early with a clear log reason.

vaderSentiment==3.3.2 added to requirements.txt.
_score_headlines now:
- scores each article (title + description) with VADER compound ∈ [-1, +1]
- filters out articles with |compound| ≤ 0.05 (no clear signal)
- weights remaining articles by recency (GNews newest-first, rank 0 → highest weight)
- returns weighted mean clamped to [-1, +1]
Removes the custom keyword sets (_POSITIVE/_NEGATIVE) and the set-based
bag-of-words algorithm that capped scores at ~±0.5 in practice.

- CACHE_TTL: 4h → 6h (≤36 req/day with ≤9 politics markets)
- GNews only called for is_politics markets (BTC/F&G cover crypto/macro)
- MAX_NEWS_QUERIES_PER_CYCLE=5: BayesianStrategy.reset_cycle() called each
iteration; counter increments only on actual API call (cache hits free)
- 2s asyncio.sleep in news.py finally block after each real HTTP request
- main.py sorts markets: politics first by end_date ascending, so soonest-
resolving markets consume the 5-query budget before others

- Drop the 'from' date filter — it's a paid GNews feature, causes 403 on free tier
- Add User-Agent header to httpx client; urllib default passes, httpx default blocked
- Log actual HTTP status code for every request (INFO) and response body on non-200
- Cache neutral result on 400/401/403/429 to avoid hammering the quota
- Remove unused _iso_days_ago() helper and 'days' param from get_sentiment()

bot/data/news.py (new):
- NewsClient with in-memory cache (TTL=4h) to stay within 100 req/day limit
- _build_query(): strips dates, punctuation and stopwords from market question
- _score_headlines(): keyword-based pos/neg vote per article, averaged ∈ [-1, +1]
- Degrades to 0.0 on missing key, 403 quota, or network error
bot/strategy/bayesian.py:
- BayesianStrategy(news=NewsClient) — optional, backwards compatible
- Signal 4: GNews sentiment applied as direct log-odds shift (weight=1.5)
so a ±1.0 sentiment score moves a 50% prior to 82%/18%
- +0.10 confidence boost when news signal is present
- NEWS_LOGODDS_WEIGHT constant documented at module level
bot/main.py:
- Instantiate NewsClient, pass to BayesianStrategy, close in finally block

Every market now emits an INFO line:
TRADE/SKIP <question> | cat=... | prior=... | est=... | edge=... | conf=... | dir=... | signals=... [| reason=...]
Unsupported-category and no-external-signals early exits also log at INFO
so the full evaluation funnel is visible without changing log level.

- polymarket.py: add keyword lists for politics (election, trump, ukraine…),
tech (AI, OpenAI, Apple, nvidia…), and events (super bowl, oscar, spacex…);
introduce _detect_category() so all four categories flow through a single
code path; filter already-expired markets (end_dt < now) in addition to
the existing future-cutoff filter; log per-category counts at startup
- bayesian.py: extend is_any_supported to include is_politics / is_tech /
is_events; use BTC as a risk-sentiment proxy for non-crypto categories
(halved weight to reflect weaker correlation); cap confidence_cap at 0.65
for macro/politics/tech/events; MIN_EDGE stays at 0.10
