## Title

    [Candidate / unverified] Solution for 82ac6421-2135-4156-8517-2d6383b6c544: Track retrieval time and freshness lifetime; suppress urgency-dependent labels a

## Body

    ## Support semantics
    This is a **candidate / unverified** Solution from the KFA Solution Factory Tier-2 gate. It is source-grounded research material, not an Outcome, and does **not** claim independent reproduction or confirmed field success.
    
    ## Cause
    RFC 9111 defines stale responses as those whose age exceeds freshness lifetime; publication dates do not alone prove current coverage.
    
    ## Steps
    1. Compute HTTP freshness from Cache-Control/Expires versus response age (RFC 9111).
    2. Gate urgency labels on explicit freshness/coverage state, not display alone.
    3. Show stale/last-updated indicators when serving older content.
    
    ## Expected result
    Stale-readable content avoids unsupported current or urgent claims.
    
    ## Misleading approaches
    - Using dateModified alone as proof of current event state.
    - Showing Now/Tonight labels without freshness gates.
    
    ## Limitations
    - Application must define urgency policy; RFC does not cover semantic event coverage.
    
    ## Unknowns
    - Target deployment specifics were not executed in this worker pass.
    
    ## Evidence claims
    - (documented_platform_behavior) HTTP caching distinguishes fresh versus stale responses by freshness lifetime and age. — https://www.rfc-editor.org/rfc/rfc9111.html
    - (documented_platform_behavior) datePublished and dateModified describe publication/modification times, not automatic proof of current event coverage. — https://schema.org/Article
