build_knowledge_graph

Clear the workspace's knowledge-graph store and rebuild from scratch. The default resumes from the durable store, reusing every extraction, embedding, and resolution verdict already paid for; a force build discards that cache — use it only when the store is suspected corrupt or the ontology's meaning changed under a version it did not re-key.

Server-minted id. Poll GET /v1/jobs/{job_id} or pass wait_seconds on create.

cancelled is a first-class terminal status, not a failed variant.

Conflating them makes error-rate metrics lie and forces every client to string-match an error code.

Display name (the console's 'project'). Public Parse, Split, Classify, Extract, and Ground runs supply a stable server default when blank; citation-generated Ground jobs are excluded. mutable via PATCH /v1/jobs/{job_id}.

Caller-minted grouping id shared by jobs submitted together. Filterable on GET /v1/jobs.

The workspace this job reads. Null for a document operation whose source is an upload, a URL, or a prior parse result.

Key that was replayed to return this job. Absent when the create call had no Idempotency-Key.

The request's own force flag, echoed regardless of outcome. Present for kinds whose request carries one (e.g. kg_build, where a true value cleared the durable store before the job ran) so a caller can tell that apart from a build that failed leaving the prior store untouched — result alone cannot, since it is absent on failure either way.

The question this job was asked, for the search kinds that carry one (intelligent_search, qa_file, qa_tables, filtered_search); null for every other kind. Read from the stored request, so it rides the same retention path as result: null once result_state leaves available. Narrow by design — the frozen access context never reaches the wire. File scope is summarised separately as query_scope.

How hard this run worked, for the search kinds that carry it. A deep-search job (kind deep_search_v2) created before the effort knob was removed echoes its requested level: 'low', 'medium', or 'high'; newer deep-search jobs, which all run one configuration, read null. An intelligent_search row carries an internal selector instead: 'fast' is fact-search, 'automatic' is automatic-search, and 'deep' (or the legacy 'balanced') is a deep-search or console QA chat job created before the 2026-09 consolidation — those two are not distinguishable by this field. Null for every other kind. Read from the stored request, so it rides the same retention path as query and result: null once result_state leaves available.

Which console history this deep-search job belongs to. deep_search is the public route and the Deep Search page; qa and workbook are the console chat skins over the same agent. It does not pick the implementation. Null for fact-search and every non-deep-search kind. Jobs stored before this field existed echo deep_search. Read from the stored payload, so it rides the same retention path as query.

Why Job.result is null.

available with a null result means the job has not succeeded yet; expired means its content was removed; not_retained means the client is provisioned zero_retention and already had its one chance to read it; cancelled means the job, or the root job it ran for, was cancelled. A cancelled job serves no results (it is not charged, including delivered parts) — not its own progressive values, and not a delegated child's result. It is a read state only, derived on the wire; no row stores it. storage_unavailable withholds a retained result while its workspace binding refuses access; Job.result_error explains the current refusal. A late poll returns the job with a state, never a 404 — "this expired" and "this never existed" are a scheduling problem and a bug respectively, and a 404 makes them identical.

Measured work in legacy credit units, retained even when a failed or cancelled job is not billed. Kept for compatibility: credits is the authoritative billed amount.

Final credits billed for this job, priced once under credit_schedule_version. Null until usage_final is true. Never changes afterwards, including after payload expiry or deletion. Failed and cancelled-before-completion jobs finalize with 0 credits, including delivered parts; ones finalized before that policy keep their credits. Always null on a stage job that Automatic Search delegated: its work is billed on the parent job.

True once credits is final and will not change. False while the job is queued or running, and until any cleanup of its delegated stages has been accounted for. A failed tool job (read_file, run_sql, hybrid_search, grep, file_metadata, folder_metadata) created with an Idempotency-Key stays false for one hour after it fails, because a retry with the same key re-runs it; after that hour it is final and the retry returns the stored error.

Version of the credit schedule credits were priced under. Null until usage_final is true.

When credits became final. Null until usage_final is true.

When the job row was created.

When execution began. Null while still queued.

When the job reached a terminal status.

Cleanup deadline after explicit deletion. Null for retained content; Zero retention uses its delivery window.

When the caller hid this run from listings, via delete_job. A soft delete: the job still reads by id and still counts toward GET /v1/usage — what it stops doing is appearing in GET /v1/jobs.
