Change-detectors, tautologies, source-reading tests, redundant duplicates, mock-echo tests and dead/unrunnable tests. Per-test rationale in the lane ledger (category + reason for every removal).

"""Contract tests for gateway.platforms.media_cache — the shared mime↔ext
|

dispatch — plus per-adapter parity spot-checks that hardcode each adapter's
|
|
HISTORICAL (pre-refactor) mappings as the contract.
|
|
|
|
If any of these fail, an adapter's downloaded-media filenames changed —

that's a behavioral regression, not a test to update casually.
