`meta`

The meta table contains exactly one row. It describes the dataset artifact, its owning Job, immediate continuation lineage, schema and engine versions, provider provenance, requested coverage, written History coverage, and quality summary.

Identity and lineage

Column	Type	Meaning
`dataset_id`	`TEXT`	Canonical Dataset UUID, generated independently from the Job ID
`parent_dataset_id`	`TEXT NULL`	Immediate source Dataset UUID for Continue in New Job; otherwise `NULL`
`job_id`	`TEXT`	Canonical owning Job UUID
`parent_job_id`	`TEXT NULL`	Immediate source Job UUID for a continuation; otherwise `NULL`
`job_name`	`TEXT`	Owning Job name snapshot
`parent_job_name`	`TEXT NULL`	Immediate parent Job name snapshot; otherwise `NULL`

Nested continuations form an immediate-parent chain. Follow parent_dataset_id repeatedly to reconstruct it; do not use display names or ShortIDs as join keys.

Version columns

Column	Type	Values and conditions
`schema_version`	`INTEGER`	`8` for current newly created datasets
`app_version`	`TEXT`	DataCat app version that created the artifact
`app_build`	`TEXT`	DataCat app build identifier
`provider_api_version`	`TEXT NULL`	Provider API/version context when available
`indicator_registry_version`	`TEXT NULL`	Registry version; `NULL` without indicators
`indicator_engine`	`TEXT NULL`	Calculation engine identity; `NULL` without indicators
`indicator_engine_version`	`TEXT NULL`	Calculation engine version; `NULL` without indicators

Job configuration

Column	Type	Values and conditions
`provider`	`TEXT`	Canonical provider identity
`venue`	`TEXT`	Canonical venue identity, even when the UI omits a redundant selector
`symbol`	`TEXT`	Provider symbol selected by the Job
`timeframe`	`TEXT`	Job timeframe
`mode`	`TEXT`	`history`, `live`, or `history_plus_live`
`warmup_bars`	`INTEGER`	Required warmup coverage for the frozen Job configuration
`indicator_table_count`	`INTEGER`	Actual number of allocated indicator output tables; `0` without indicators

Quality and coverage

gaps_remaining counts persisted gaps rows whose status is not resolved. It includes pending, open, and exhausted rows and is not the same as a provider-policy-filtered app presentation such as Open Gaps.

The canonical computation timestamps are integer milliseconds. Matching UTC text columns exist for manual inspection:

Milliseconds	UTC text	Nullable condition
`created_at_ms`	`created_at_utc`	Never
`requested_start_ms`	`requested_start_utc`	Can be `NULL` only when no start boundary applies
`requested_end_ms`	`requested_end_utc`	`NULL` for open-ended Live and History + Live
`history_written_start_ms`	`history_written_start_utc`	`NULL` in pure Live mode
`history_written_end_ms`	`history_written_end_utc`	`NULL` in pure Live mode
