How this service works
Compare Timestamped source search for roadmap discussion wording; literal vocabulary only. against a bounded caller-supplied previous snapshot and return exact change witnesses. Baseline is caller supplied and is never authenticated as historical server output. Pure bounded timing/source-quote validation runs before payment. Exactly one current motor call, zero baseline provider calls. Full current provider disclosure retained; baseline is not submitted to the provider.
Output
A structured JSON response listing exact change witnesses: added, removed, or modified literal text passages found by diffing the caller-supplied previous snapshot against the freshly retrieved current roadmap literal-keyword search results, including timestamps and source quotes for the current results.
Example use cases
Roadmap wording drift detection
“I saved a snapshot of the engineering roadmap literal index last month — can you compare it against today's results and tell me exactly which roadmap discussion phrases have changed or disappeared?”
Sprint planning vocabulary audit
“Check whether the wording around 'milestone delivery' in the engineering roadmap index has changed since this snapshot I'm providing — I need the exact text differences highlighted.”
Release note consistency check
“Compare the current roadmap discussion search results for 'feature freeze' against this previous snapshot and return any exact quote changes so I can confirm the wording is still consistent.”

Endpoint
POSThttps://medien.halowerk.com/v1/baumarkt/media/engineering-roadmap-literal-index/snapshot-compare?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect exact literal wording changes in engineering roadmap discussion text between a known prior state (your own saved snapshot) and the current indexed results. It is purpose-built for literal vocabulary validation — not semantic search or NLP-based change detection. Prefer it over general diff tools when you need timestamped source-quote evidence of changes and when you control the baseline snapshot yourself.
Side effects
- Caller-supplied baseline snapshot is malformed or missing — returns validation error
- Literal keyword query returns no current results — empty diff with no witnesses
- Snapshot format mismatch between caller baseline and current provider response structure
- Rate limiting or provider unavailability causes current fetch to fail — returns provider error
- Overly broad or ambiguous literal keyword produces too many results — may truncate or timeout
