- config.set_proxy gains password_env (aligned with api_key_env
convention): config file persists only the env var name; plaintext
password lives in memory for the current session only
- _save_config deep-copies and nulls proxy.socks5.password before
json.dump, so every save path is sanitized (defense in depth)
- get_proxy resolves password as in-memory plaintext first, then via
password_env from os.environ; downstream consumers (llm_client,
web tool curl args) unchanged
- legacy migration on load: plaintext found on disk is kept in memory
for the session, file is immediately rewritten sanitized
- SetProxyTool exposes password_env and reports password source
- registry debug logs mask password/api_key/token/secret/authorization
kwargs (N11)
Tests: new tests/test_config.py (3 cases: no plaintext on save,
password_env resolution, legacy migration); full suite 267 passed.
Audit report updated with Batch F progress.
- H1: CommandLineTool.execute_streaming now purely delegates to injected
executor; removes 150-line duplicate Popen loop that bypassed 1MB cap,
cancel() and timeout protections
- H2: thread the blocking readline into a daemon reader thread; main loop
polls queue with 0.1s ticks so timeout/1MB checks fire even for silent
commands (verified: 3s timeout on 15s sleep, was 15s+ before)
- H3: stdin=DEVNULL on both Popen sites; stdin-waiting commands now hit
EOF instead of deadlocking the tool thread forever
- M1: heredoc delimiter uniquification in write_file guidance (content
line equal to AIBOX_EOF no longer truncates into shell injection)
- M2: 3600s total deadline on registry streaming forward loop
Verification: PoC regression 5/5 PASS (timeout/1MB/cancel/delegation),
full unit suite 264 passed. Audit report updated with Batch E results.
