 `npm run veritas` executes the real local gate before a release or verified answer: compile checks, tests, Git whitespace checks, manifest validation, path boundaries, and secret scanning. It is intentionally allowlisted and does not execute arbitrary model-generated commands.
 
+## Journalism Desk
+
+The local CaseFile workflow in the UI creates a private case, imports local evidence, records SHA-256 receipts, and extracts date anchors before model analysis. See `community/journal-desk.md` and `community/casefile-schema.json`.

 ## Status
 
 This is a pre-production engineering release. The Liquid checkpoint is not included until its exact artifact, license, checksum, and evaluation are confirmed. The Qwen weight is downloaded separately from its official repository and should be verified before offline use.

+# AIDE Journal Desk
+
+The Journal Desk is the first journalism workflow in the IDE. It works without a model or network connection.
+
+## Local CaseFile Flow
+
+1. Create a CaseFile with a private boundary.
+2. Import local text evidence.
+3. Compute a SHA-256 receipt for every file.
+4. Extract date anchors for timeline work.
+5. Preserve the provenance record before sending selected evidence to a model.
+6. Later run the evidence through source-DNA, timeline, discrepancy, pattern, and editorial-review tools.
+
+The browser prototype stores only the case metadata, hashes, and date anchors in local storage. It does not upload evidence. The production daemon will store encrypted CaseFiles outside the browser and will require an explicit boundary change before group or public replication.
+
+This is not a truth guarantee. A hash proves which bytes were reviewed, not that the document is authentic or that its claims are true. Authenticity requires provenance, corroboration, signatures, and human judgment.
