How this service works
Compare pinned study-note projections for source, locator, claim-kind and confidence-basis changes. A changed declaration does not establish improved evidence or truth. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.
Output
A structured delta map identifying field-level changes between the two pinned study-note projections, covering source, locator, claim-kind, and confidence-basis dimensions. Results are retained for 24 hours; minimal receipt metadata persists for 90 days. The map does not assert improved evidence or truth from any changed declarations.
Example use cases
Auditing claim-kind drift in notes
“I have two frozen snapshots of a study note from different revisions — can you diff them and show me exactly which claim-kinds changed between the before and after versions? Data class is public and it's all non-personal metadata.”
Detecting confidence-basis shifts
“These two study-note projections represent the same note at different points in time. Run a revision delta map on them and highlight any changes to the confidence-basis fields — I want to know if the evidentiary grounding shifted between revisions. Use public data class.”
Source and locator change audit
“Can you compare my before and after study-note snapshots and produce a delta map focused on source and locator changes? Both are synthetic data class and contain only non-personal metadata — I just need to know if any source references or locators were swapped between revisions.”
Technical details
Endpoint
POSThttps://www.mahastrategies.com/api/v1/context/study-notes/revision-delta-map?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured field-level diff of study-note projections across two pinned revisions, specifically tracking source, locator, claim-kind, and confidence-basis changes. Prefer it over general-purpose diff tools when working within the Maha Strategies study-notes domain with offline, non-personal metadata under the 24-hour result retention constraint. Use sibling endpoints (e.g. Study Notes — Duplicate Record Identities) if the goal is identity deduplication rather than revision comparison.
Side effects
- Missing or malformed 'before'/'after' objects — request rejected with validation error
- nonpersonalMetadata not set to true — const constraint violation causes rejection
- Invalid dataClass value outside 'public' or 'synthetic' enum — schema validation failure
- Mismatched projection schemas between before/after snapshots — delta computation may error or return incomplete results
- Stale results beyond 24-hour retention window — results no longer retrievable
