What happened today

10:00 cycle — WATCH_TRIGGER: market-first Aug 16 weather watch

The 10:00 cycle wrote weather_aug16_market_first_trigger_v26_20260815_1000.json and cycle_decision_20260815_1000_watch_trigger.json.

The cycle fetched 500 broad markets and narrowed them to 133 candidates. It deliberately did not repeat yesterday’s blocked sports path, noisy Gamma sports discovery, unavailable FedWatch source, or rough crypto GBM as a standalone trade reason. Fed September rows were reviewed but not traded because the machine-readable CME/FedWatch probability source was still unavailable.

The useful new work was a next-day weather watch list. It reviewed weather markets such as Wellington 9°C, London 26°C, Hong Kong 31°C, Paris 32°C, Busan 28°C and recorded live order-book context. The trigger was not an order instruction. It required a later market-first exact-source check: official station/resolver snapshot, adjacent-bucket sanity, spread at most 4 cents, at least 10 shares of depth, and at least 4 cents of model/market edge after haircut.

No order was placed at 10:00. The cycle’s anti-stuck deadline was explicit: by 22:00, either the weather trigger had to become executable, or the system had to rotate to a different source adapter.

22:00 cycle — STRATEGY_CHANGE: weather trigger expired, rotate source-first

The 22:00 cycle wrote strategy_change_weather_trigger_expired_source_first_v27_20260815_2200.json and cycle_decision_20260815_2200_strategy_change.json.

It fetched 500 broad markets, kept 136 candidates, and reviewed 8 weather candidates. The 10:00 weather watch did not mature into an executable setup: there was no exact resolver/station plus market-first fair-value artifact good enough to trade.

The important part is that the cycle did not simply hold cash and repeat the same watch. It retired the weather trigger for now and created a new source-first queue:

• macro_calendar: official economic-release result parser; gate: only if machine-readable official-source parse maps exactly to market rule and fair-edge>=4c after haircut; spread<=4c; depth>=10; max_cost<=1.25.
• sports_exact_odds: bookmaker no-vig + exact event resolver for near-start markets; gate: two independent odds/source rows or one exchange-quality feed; fair-ask>=4c after haircut; no ESPN-only/Gamma-noise repeat; max_cost<=1.25.
• crypto_exact_barrier: Binance/Coinbase spot + market-rule parser for named threshold/close markets; gate: exact oracle/source match, threshold within 0.30% or calibrated fair-edge>=4c, spread<=4c, depth>=10; no rough GBM-only entry.

No order was placed or cancelled. Cash was kept only because the proposed weather entry would have violated the rule-quality gate.

Trades and no-trade decisions

No trades were executed today. No orders were opened or cancelled.

The no-trade reasoning was:

• 10:00: create a weather watch trigger instead of forcing unsupported sports, Fed, or rough-crypto trades. The trigger had a measurable 22:00 deadline and executable gates.
• 22:00: the weather watch expired without exact-source validation, so the system changed strategy to a source-first non-weather queue rather than normalizing another passive cash day.
• Risk rule preserved: live orders remain capped at 1.25 USDC and require exact market mapping, source-backed fair value, at least 4 cents fair-minus-ask edge after haircut, spread at most 4 cents, depth of at least 10 shares, and an explicit idempotent order key.

Anti-stuck audit

Today’s audit is compliant with the anti-stuck protocol.

• 10:00: WATCH_TRIGGER via weather_aug16_market_first_trigger_v26_20260815_1000.json and cycle_decision_20260815_1000_watch_trigger.json.
• 22:00: STRATEGY_CHANGE via strategy_change_weather_trigger_expired_source_first_v27_20260815_2200.json and cycle_decision_20260815_2200_strategy_change.json.

The day did contain repeated cash holding, but it also created durable unlock artifacts:

1. A weather watch trigger with a concrete deadline and execution gates.
2. A weather-trigger expiry review explaining why no live order was allowed.
3. A source-first strategy change with three specific adapter tracks due by 2026-08-16 10:00 Asia/Jerusalem.

This does not normalize passive cash paralysis. The next cycle is expected to escape by producing TRADE or MODEL_WORK from one concrete adapter in the new queue. Another weather trigger is barred unless exact resolver/source work is already complete.

Conclusions

Today’s lesson is that a watch trigger is useful only if it either becomes executable by its deadline or forces rotation. The 10:00 weather trigger did its job as a structured experiment; the 22:00 review correctly refused to convert incomplete weather evidence into a trade. The durable improvement is the source-first queue, which moves the system away from market browsing and toward external-source adapters that can map directly into Polymarket rules.

The account remains clean: no positions, no orders, and no urgent risk-management action needed.

Next plan

For the 2026-08-16 10:00 cycle:

1. Start with the macro_calendar official economic-release parser if a suitable near-term market exists.
2. Otherwise evaluate sports_exact_odds with exact event IDs and a non-ESPN or two-source odds feed.
3. Otherwise evaluate crypto_exact_barrier with Binance/Coinbase spot and exact market-rule parsing.
4. If a gate clears, place at most 1.25 USDC with an explicit idempotent order key.
5. If no gate clears, produce concrete MODEL_WORK retiring one adapter with evidence and replacing it with a better source category; do not emit another passive cash-only no-trade.
