Each entry describes its recorded operation and source revision.
Review signals across current setups: connection review, sensitive read. 48 listed items (named-host connections, static matches, dependency advisories) are below and do not change this verdict.
Repository processes attempted these non-loopback connections; proxies can hide the final hostname. 4 distinct locations. 2 findings. 26 attributed processes.
OSV reports a known vulnerability in this dependency version. 3 distinct locations. 24 findings.
A repository process attempted to read this sensitive path. Kind of file: cloud login. 2 findings. 13 attributed processes.

Local or hosted: local
Suggested next step (agent-reported): Scheduled runs should create a crawl record and return its id: pass a session id (or create the crawl row) in the scheduled runner path, so run-now and the 30-second scheduler tick produce a readable crawl. Add a test that calls the run-now route and checks a crawl with a non-null id exists. Browser UI tests should accept a CDP endpoint or document the Chromium prerequisite.

Operation / attempted scope Python 3.12.3 with README requirements installed in /tmp/toadstone-venv; no local browser installed
Agent-reported scope: Run the README documented fixture coverage sweep
The README documented fixture sweep exceeded the execution ceiling during both direct execution and checker replay.

Failed run: spcaeo/toadstone · Oct 26, 2026 · Recorded operation failed.
Fix: fix-95789084a472d57f2c74.
Step: Coverage sweep does not finish inside the 300 second execution ceiling, so replay and checker validation cannot complete.
The README documented fixture sweep exceeded the execution ceiling during both direct execution and checker replay.
Review signals: 24 known vulnerability, 1 sensitive read.
Reviewed as expected for a test run: attempted writes that failed, so nothing was written.
OSV reports a known vulnerability in this dependency version. 3 distinct locations. 24 findings.
A repository process attempted to read this sensitive path. Kind of file: cloud login. 3 attributed processes.
OSV scanned supported lockfiles; unpinned dependencies and unsupported formats are outside this check.
A short run cannot establish that code is safe.
Connections show IP addresses; proxies can hide the final hostname.
Tracing covers dispatched commands and their children, not the whole OS; guest root can interfere with tracing.
Local or hosted: local
Suggested next step (agent-reported): Run the fixture sweep and evidence checker in an environment with a longer execution window.

Source: README.md
Expected: documented command completes successfully
Observed: Deferred on purpose: python tools/coverage_sweep.py runs about six full crawls of a local fixture site, a long run outside this check. The one-command CLI crawl and the MCP list_issues call were run instead.
Source: src/core/scheduler.py
Observed: Not run: the scheduler runs only inside the long-lived server process (main.py _start_scheduler). Its only trigger is Scheduler.tick(now) called from a background loop, and there is no documented one-shot command or CLI to trigger one cycle. Triggering it needs a stored standing-crawl job plus a fake clock wrapper, which was not built in this run.
Local or hosted: local
