v2.26.1

Features

• Exact-pool OHLCV observations — candles bind to the exact venue/pool, authenticated end-to-end through the gateway. (#3777)
• Exact Uniswap-V3 TWAP observations — resolve the exact pool; fail closed on provider/transport faults. (#3749)
• Exact-venue binding for Curve swaps — bind to a verified pool identity, reject malformed venue identity. (#3768)
• Exact-venue binding for Slipstream (Aerodrome CL) LP — bind to receipt-derived NPM manager generation; teardown resolves CL manager authority from connector-owned roles. (#3747)
• Fail-closed exact data consumer across SDK seams — reconcile exact binding identity across market-data and execution seams. (#3773, #3776)
• Compound V3 accepts a Comet address as market_id — the exact-venue path Aave and Fluid already have, with expected_pool as a supply/withdraw assertion. (#3774)
• Backtest feasibility preflight — reject infeasible windows before data materialization with an actionable WINDOW_TOO_LONG blocker, not a job timeout. (#3780)
• Structured backtest preflight blockers — preflight failures arrive as structured {failure_stage, code, blockers} artifacts/callbacks, preserved across redelivery. (#3779)

Changed

• quote_asset documentation clarifies the reporting numeraire — guides, docstrings, and the strategy-builder skill; config override scoped to live runs. (#3791)
• Almanak Code updated to v1.0.49 (#3790)

Fixes

• CoinGecko pool discovery hardened — chain-family cache case, transient-failure tolerance, bounded provider caches. (#3789)
• Teardown completeness by asset identity — reconciled against exact historical asset identity instead of symbol-derived matches. (#3778)
