Research intake you can re-check.

Extract source structure, keep the lineage, seal what survives, and re-hash the evidence later.

Gather 1.6.1 / local fixture / no network / hashes unchanged / source

The 29-second proof

Gather converts local source material into addressable, content-hashed blocks, scopes the useful documents into a corpus, and verifies that the stored bodies still match their provenance records.

Silent, captioned on screen. The path-sanitized command transcript and machine-readable evidence are linked below.

The observed result

7extracted blocks

2records stored

0documents dropped

2 / 2MATCH

Extract: 7 extracted blocks retain source-node paths and SHA-256 fingerprints.
Scope and store: two local notes added, 0 deduplicated, and 0 dropped.
Recall: corpus search returns both relevant bodies with their fingerprints attached.
Re-check: corpus verification re-reads both stored bodies and returns 2 / 2 MATCH.
Failure path: the bundled integrity drill changes one receipt, returns False, and the workflow shows TAMPER CAUGHT.

The full 116-second workflow

The long cut preserves all seven real commands: version, extraction, scoped document intake, corpus search, corpus verification, digest creation, and the tamper drill. Every displayed hash, count, seal, return code, and verdict comes from the captured evidence file.

Claim boundary

This is a local, sanitized fixture designed to make the evidence easy to inspect. It proves the extraction, scoping, content-addressed storage, recall, verification, digest, and tamper-detection paths shown here. It does not claim coverage of every live web source, authenticated route, OCR engine, or document format.

Recorded and verified 2026-07-12. Both videos are H.264, 1920 x 1080, 30 fps, and contain no audio. They decoded successfully end to end, and the evidence package passed path and credential hygiene checks.
