The todos pre-scan walked .output/ (Nitro) and .vercel/ (Vercel) build
dirs, flagging 119 of 124 candidates inside minified bundles (single
lines up to 162KB). buildTodosScanTask embedded full candidate lines in
the task prompt, producing a 2.5MB prompt on freno-dev; the analysis
agent settled with ok:true + empty text + no findings.md, verify failed,
and resume re-ran the same oversized prompt and failed identically.
- scope: exclude .output/.vercel/.netlify (shared by all checks)
- todos: truncate candidate code at 160 chars in the prompt + fallback
- agent-runner: a session settling with no text and no observed message/
tool events now fails the run loudly instead of reporting ok:true
- agent prompts: add the three dirs to each skip list
- tests: excluded-dir scan, prompt truncation, emptySessionError cases
A stalled sub-agent (provider stream never settling after the final tool
call, or a throwing session-event listener recursing through the SDK's
run-failure path to stack overflow) left the phase stuck in_progress with
no state save, no error, and no completion message — observed twice in
freno-dev, both times after comments wrote findings.md.
- agent-runner: 60-min settle watchdog on every agent phase
(PYGIENIUM_AGENT_TIMEOUT_MS, env-tunable); timeout disposes the session
and fails the phase loudly with a /pygienium-resume hint instead of
hanging the check-runner's await forever.
- agent-runner: applySessionEvent — the session.subscribe listener can no
longer throw into the SDK event pipeline (guards for partial/malformed
events, optional-chained message_update, throwing chat forwarder).
- comments: scan no longer regenerates the full report as its final
message (findings.md is the source of truth); fix phase reads
findings.md with embedded fallback.
- check-runner: failing state-save inside the catch path can't double-
fault or escape as an unhandled rejection; completion posting is
best-effort.
- tests: watchdog timeout test, comments task-text regression tests,
applySessionEvent malformed-shape unit tests. 146 pass, tsc clean.
