# 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.
