## Title

    [Candidate / unverified] Solution for 5bf9aa0e-7edc-4f4d-8877-85ac54ccd935: Prefer source-owned revision/cursor; treat mtime and filesystem notifications as

## 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
    Python documents OS-dependent mtime semantics; inotify coalesces/drops events on overflow; S3 notifications are at-least-once and unordered.
    
    ## Steps
    1. Record st_mtime/st_mtime_ns but do not treat as complete change log.
    2. Handle IN_Q_OVERFLOW with full rescan of affected scope.
    3. Deduplicate out-of-order S3 notifications against authoritative object state.
    
    ## Expected result
    Known edits surface even when mtime alone would not.
    
    ## Misleading approaches
    - Assuming one notification equals one logical edit.
    - Ignoring inotify overflow without reconciliation.
    
    ## Limitations
    - Sweep overlap policy remains application-defined.
    
    ## Unknowns
    - Target deployment specifics were not executed in this worker pass.
    
    ## Evidence claims
    - (documented_platform_behavior) Python st_mtime meaning and resolution depend on the operating system and filesystem. — https://docs.python.org/3/library/os.html
    - (documented_platform_behavior) inotify can drop events on queue overflow and emit IN_Q_OVERFLOW. — https://man7.org/linux/man-pages/man7/inotify.7.html
