MAIN TX watcher usage
Purpose
tools/tx_agent_watcher.py is an ordinary local Python process. It polls the small RX result on origin/rx-node. It does not call an LLM and does not open HackRF hardware.
Start
From the repository root, double-click:
tools\start_tx_watcher.cmd
The visible console polls every 5 seconds. A missing rx-node branch or invalid result is reported. No model runs while polling.
READY and RED approval
RF_HANDOFF_CHANNEL_TEST_001 READY and COMPLETE states are recorded without a RED prompt and never open the production gate.
For a fresh valid RF001A_OTA_CAPTURE_003 READY result, the watcher checks the expected source HEAD, current origin/rx-node commit, common clock and capture window. It then prints the task ID, capture start and expected end and asks for:
AUTHORIZE RF TX
Any other input blocks authorization.
After the exact phrase, the watcher fetches rx-node again. It requires the same result digest and commit, the expected source HEAD, a fresh publication, an active 120-second capture window, verified common clock and at least 10 seconds remaining.
On success it writes:
.local\tx_authorizations\RF001A_OTA_TX_003_authorized.json
This record opens the gate for the separately controlled TX executor. The watcher itself does not run hackrf_transfer. The record explicitly says rf_tx_started = false and rf_tx = 0.
The TX executor must re-fetch rx-node and compare the result commit and digest immediately before hardware access.
Stop
Double-click:
tools\stop_tx_watcher.cmd
The stop command writes a local stop request and waits for the watcher PID to clear.
Fake mode
Automated tests use a local bare Git repository. For a single local JSON fixture, the CLI dry-run form is:
python -B tools/tx_agent_watcher.py --dry-run --once --result-file <ready-json> --approval authorize
The --approval option is rejected outside --dry-run. Fake mode writes a local fake authorization and never fetches the production remote or accesses SDR hardware.
