Two new exception handlers inserted BEFORE the shared `TRANSIENT_TRANSPORT_EXCEPTIONS` handler so they win Python's first-match: (1) `BrokenPipeError` / `ConnectionResetError` → client-side transport drop (upstream MCP-sync cancellation cascading into a pooled keepalive socket); returns `reachable=False` with `error="Connection dropped: "` but does **NOT** call `circuit.record_failure()` — the agent's health was never observed, so it must not trip the breaker on healthy agents. (2) `httpx.ReadError` / `httpx.WriteError` / `httpx.RemoteProtocolError` → genuine agent liveness signals on a `/health` probe (partial write then socket drop = event-loop wedge, OOM mid-write, segfault); calls `circuit.record_failure()` and returns `reachable=False` with `error="HTTP transport error on /health: "`. This is the documented `/health`-specific divergence from `AgentClient._request()` — on `/api/*` paths #798's tuple-based handler keeps the same exceptions circuit-neutral because the cause space is broader.

Any HTTP response (200..599) records circuit success so stale failure counters clear as soon as the agent answers. Only `ConnectError`/`ConnectTimeout` increment the failure counter; read-timeouts, pool exhaustion, mid-write broken-pipe/reset, and garbled framing surface as `reachable=False` but don't poison the circuit. `aggregate_health()` adds an explicit `network.status_code >= 500 → UNHEALTHY` branch (`monitoring_service.py:419`) so a wedged-but-listening agent isn't silently HEALTHY under the new rule. | | 2026-03-03 | **SUB-002 credential monitoring removal**: Removed credential file checks from `check_business_health()`, `aggregate_health()`, and `perform_health_check()`.

PR #873 applied the same pattern — handler at `headless_executor.py:856-874`, semantically identical to the `gemini_runtime.py:665-676` sibling — ensuring the pipe-drop → HTTP 502 reclassification and INFO-level logging survive the module split. No behaviour change; pure carry-forward of the #474 fix. `src/frontend/src/composables/useProcessWebSocket.js` was deleted as part of this cleanup (composable was no longer used after the SSE streaming surface was consolidated). | | 2026-05-13 | **Issue #474 - Subprocess pipe-drop misclassified as HTTP 500 (and triggering SUB-003 auto-switch on the 503 sibling path)**: When the agent-server tried to write a task request to the Claude (or Gemini) subprocess and the child had already exited — typical causes: OAuth/auth abort, permission-mode validation kill, upstream cancellation by the backend's `terminate_execution_on_agent()`, or any race where the child closes stdin before the parent finishes writing — the resulting `BrokenPipeError` / `ConnectionResetError` fell through to the generic `except Exception` clause and surfaced as HTTP 500 with a misleading `[Errno 32] Broken pipe` ERROR log line. The 503 sibling shape of this failure additionally collided with SUB-003 (`services/task_execution_service.py:628`) which interprets any 503 from an agent endpoint as auth-class failure and auto-rotates the subscription — meaning a benign pipe drop could spuriously burn through subscription rotations. Fix: dedicated `except (BrokenPipeError, ConnectionResetError) as pipe_err` handler inserted *before* the generic `except Exception` clause in both runtimes — `docker/base-image/agent_server/services/headless_executor.py:814-832` (Claude path) and `docker/base-image/agent_server/services/gemini_runtime.py:665-676` (Gemini path) — both raise `HTTPException(status_code=502, detail="Agent subprocess closed before task could complete")`. 502 ("Bad Gateway to Claude subprocess") is semantically correct and collision-free: SUB-003's 503-or-auth-string predicate at `task_execution_service.py:628` ignores 502, so 502 flows through as plain FAILED without rotating the subscription. Log level downgraded to `logger.info()` (not `logger.error()`) because the pipe drop is a known benign race — ERROR-level spam misleads operators into hunting non-existent server-side faults. Sibling of #520 (502 for empty result) and #516 (504 for signal exit) — same pattern of "give the symptom a precise HTTP code so backend classification doesn't conflate it with auth failure." Regression tests: `tests/unit/test_headless_executor_pipe_drop.py` (handler behavior, status code, log level, ordering relative to the generic catch-all) and `tests/unit/test_pipe_close_no_auto_switch.py` (asserts SUB-003 does NOT trigger on 502 from the pipe-drop path). | | 2026-05-12 | **Issue #808 - orphan-killer daemon thread spins at 100% CPU for ~15 min, starving uvicorn health probes and triggering circuit breaker**: Previous fixes (#649, #730, #747) bounded how long the *caller* waits for the orphan scan, but the daemon thread itself continued running at default (normal) scheduling priority. On 1-CPU containers a thread spinning at 100% preempts all other runnable threads — the uvicorn event loop cannot service health probe requests, probes time out repeatedly, and the circuit breaker (#631) opens and stays dormant for ~40 minutes. Two complementary fixes (`subprocess_pgroup.py`): (1) `_set_idle_priority()` — called at the start of `_run_orphan_killer()`, sets the daemon thread to `SCHED_IDLE` (Linux kernel "run only when nothing else wants CPU") via `os.sched_setscheduler(0, os.SCHED_IDLE, os.sched_param(0))`; falls back to `os.nice(19)` on non-Linux POSIX (macOS CI); no-op on other platforms. (2) `_scan_deadline = time.monotonic() + _ORPHAN_SCAN_WALL_SECONDS` (8 s) — passed as `_scan_deadline` kwarg to `_kill_orphan_pipe_writers`; per-iteration `time.monotonic() >= _scan_deadline` check in the `/proc` loop aborts scanning after budget expires, bounding total CPU time regardless of individual `readlink()` delays from D-state processes. 8 s is inside the existing 11 s `asyncio.wait_for` ceiling with 3 s margin. `_kill_orphan_pipe_writers` signature changed from `(pipe_read_fd, our_pgid)` to `(pipe_read_fd, our_pgid, _scan_deadline=None)` — keyword-only, backward-compatible. Tests: mock `_slow_orphan_killer` signature updated (`_scan_deadline=None`); new `TestKillOrphanPipeWriters.test_scan_deadline_stops_scan_early` (passes expired deadline, asserts scan aborts in < 1 s); new `TestSetIdlePriority` (does_not_raise, idempotent). | | 2026-05-09 | **Issue #728 (follow-up) - `os.stat()` on `/proc/pid/fd/N` blocks indefinitely on D-state processes, causing orphan scan to silently miss orphan writers**: `_kill_orphan_pipe_writers` used `os.stat(f"/proc/{pid}/fd/{fd_name}")` to follow the symlink to the pipe inode and then read `/proc/{pid}/fdinfo/{fd_name}` to check write/read flags. Both operations acquire the inode lock at the kernel level; on a D-state (uninterruptible sleep) process this lock may be held indefinitely, causing the entire 10 s orphan-scan daemon thread to exit its cap without ever reaching the orphan writer. Fix (`subprocess_pgroup.py`): replace `os.stat()` + fdinfo with `os.readlink(f"/proc/{pid}/fd/{fd_name}")`. On Linux `/proc/pid/fd/N` is a symlink whose target text is `"pipe:[inode_number]"` — `readlink()` reads this string from proc's own metadata without following the symlink and without acquiring any inode lock, making it safe to call on D-state processes. The fdinfo write/read flag check is removed entirely: an explicit `our_pid = os.getpid()` self-skip is added so the read-end holder is excluded unconditionally; all remaining holders of the target pipe inode outside the killed pgid are by definition orphan writers. Regression test added: `tests/unit/test_subprocess_pgroup.py` — `TestKillOrphanPipeWriters.test_kills_orphan_even_when_stat_raises_dstate_simulation` monkeypatches `os.stat` to raise `OSError` and verifies the orphan is still found and killed via the `readlink` path (would have FAILED against the old implementation).
