Add a per-stream op channel in AudioRingHeader (op_seq + op_* fields, version 2): the host posts re-measure / override commands, the hook applies them and re-publishes (bumping format_generation), and the host rebuilds its render client live on the change. The Audio panel (under Debug details) gains a "Re-measure rate" button and a rate/channels/bit-depth/format override -- for when detection is wrong or the channels/bit-depth were unrecoverable. Also add a debug-only IPC test harness (-DCOOP_TEST_HARNESS, off by default, absent from the shipped host): a file-based command channel that drives the host's real UI code paths (inject / audio / re-measure / override / screenshot / status) for scripted validation, instead of unreliable synthetic mouse input. Used to validate live: late-attach to coop_tone@44100 -> measured 44100, promoted to hooked; override -> 2ch state, re-measure -> reconverge. Trim the README roadmap to what's left; document the harness + rate_estimator_test. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

// Debug-only IPC test harness (compiled only when COOP_TEST_HARNESS is defined; the
|
|
// shipped product never contains it). Lets a test script drive the real overlay code
|
|
// paths -- inject, enable audio, re-measure, override, etc. -- by writing a command to
|
|
// %TEMP%\coop_test_cmd.txt and reading the reply from %TEMP%\coop_test_resp.txt, instead
|
|
// of simulating mouse/keyboard input (which ImGui doesn't accept reliably via PostMessage).
|
|
//
|
|
// Protocol: the driver writes one command line to the cmd file; the host consumes it
|
|
// (deleting the cmd file to ack), runs it on the main thread (so it hits the same code
|
|
// the UI buttons do), and writes a single response line to the resp file. One command at
|
|
// a time. See tools/test_drive notes / the per-phase validation scripts.
