# Get Project Knowledge Summary

`GET /api/projects/{project_id}/knowledge-summary`

## Path parameters

- `project_id` string, required

## Query parameters

- `recent_limit` integer
- `refresh` boolean

## Response `200`

Successful Response

- KnowledgeSummaryResponse
  - `counts` object, required
  - `recent` KnowledgeSummaryClaimResponse[]
    - `claim_id` string, required
    - `claim_type` 'runtime-captured' | 'synthesized' | 'tabular' | 'figure' | 'file-captured', required — Claim type constants. Runtime-captured evidence is a variable value read out of a live runtime — a notebook kernel (autocapture on cell run, or a cell-side ``qualia`` call) or a script process running under ``bash_command``. The value must come from the runtime; it can never be supplied as an agent tool argument. These are the primary source of evidence in the knowledge graph. A notebook is one runtime among several, which is why this type is not named for it. Findings (claim_type='synthesized' internally) combine 2+ existing claims into higher-order conclusions that interpret what the evidence means—not only restate source values. Tabular claims store structured data matrices with per-cell source references. Figure claims link to chart/visualization outputs captured from notebook cells. File-captured claims record a text span read by the backend from a workspace file (script, results file, log, etc.); like figures, the value is read from the source, never supplied by an agent tool argument. Claims from the retired knowledge-import pipeline were backfilled into this type.
    - `label` string, required
    - `review_status` 'pending' | 'accepted'
