Interrupted backfill can leave stored observations separated by
missing trading time. Query dated IB sessions before prepending
stored history and reserve synthetic samples only during covered
open sessions. Keep venue closures compressed and preserve the
indexes of already published rows.
Deats,
- Add `Client.history_schedule()` with UTC coverage, extended hours,
bounded duration, timeout, and rejection of ambiguous DST times.
- Keep schedule normalization in `venues` and allocation in
`.tsp._reserve`, with the project AGPL headers.
- Expose schedule and synthetic-range queries through `datad.ib`.
- Bound reservations by available SHM capacity and inspect only the
newest 32 gaps by default via `newest_gaps`. Zero disables
queries; leave unknown and oversized ranges unresolved.
- Record synthetic ranges separately from OHLCV. Automatic storage
writes retain provider observations; placeholders copy close.
- Group the new tests under `tests/providers`.
- Cover request formatting, DST, failure and capacity cases, plus
real SHM/NativeDB startup placement with a fake provider.
- Document a common CLI/chart segment-repair interface and defer
coordinated insertion, repair execution, and reader integration.
Validation: 55 targeted tests passed in the working tree; live IB
schedule coverage remains unqualified. After the module moves,
33 affected tests passed again; the local review follow-up passed
18 affected cases, including four new request-budget cases.
The commit runner repeats
lint and isolated regression checks against this exact boundary.
