…mbol Bare BA / settlement-point symbols (e.g. 'aeci') are intentionally not in the static symbology reverse index, so mode_for_symbol() raised on them and both write_bars() and read_as_of() failed for power.* libraries. Add an optional explicit mode (a property of the library via mode_for_library()); power callers (asset, check, read API) pass it. Caught by a live EIA-930 ingest smoke test; locked with symbology + storage round-trip regression tests.

Refocuses Energex on power markets, additively on the existing hexagonal bitemporal platform (core, pandera gate, Dagster, read-API seam all unchanged).
Part A — EIA-930 (live)
Eia930RegionConnector+Eia930FuelConnector: hourly demand / day-ahead forecast / net generation / interchange + generation-by-fuel for all ~60–70 US balancing authorities via EIA v2electricity/rto/*.power.{demand,demand_forecast,generation,interchange,generation_by_fuel}.degenerate(latest-wins) revision mode.power.*symbology routing (no static enumeration of BAs).POWER_REGION+POWER_GEN_BY_FUELpandera gates; Dagster assets, read-back checks, hourly schedule; ~3-yr backfill partition.Part B — ERCOT nodal (dormant until creds)
ErcotSppConnector(OAuth2 ROPC): RT + DA settlement point prices →power.lmp,bitemporal_merge.ERCOT_USERNAME/ERCOT_PASSWORD/ERCOT_SUBSCRIPTION_KEY; schedule shipsSTOPPED(no failing runs).ERCOT_SPP/ERCOT_LOAD/ERCOT_FUELMIXgates (replace the oldERCOT_DALMPstub).Other
*_legacy).fix(storage): route power reads/writes by library mode (mode_for_library) since bare BA symbols aren't in the static reverse index — caught by a live ingest smoke test, locked with regression tests.201 tests pass; ruff check + format clean; dagster definitions validate.
