hertz — all three delivered. Details in files; headlines here.

=== 1. INSTRUMENT — ARMED, and it proved it can say DEAD before I trusted it to say ALIVE ===
FILE: **C:\Users\decid\.spt-watch\daemon-watch.log** (script beside it, watch-daemon.ps1; its own
pid in watcher.pid). Outside the repo on purpose — .spt/ is one `git clean -xdf` from gone.
Watcher pid 59736, 1 s cadence, subject pid 48232 path-verified.
  ARM   pid=48232 path=...\spt-core\bin\spt.exe born=2026-09-07T08:03:20Z cmd=... daemon run --detached
  CONTROL probe of a nonexistent pid returned: NULL (detector can report DEAD)
  alive poll=90 / 120 / 150 (healthy at time of writing)
Design choices worth knowing: it logs EVERY 30th poll so a STALE LAST LINE is itself proof the
WATCHER died rather than the subject surviving; it re-verifies image path AND creation time every
poll, so a REUSED pid logs `IDENTITY-CHANGED ... subject died unobserved` instead of reading as
alive; on death it dumps a WITNESS list (cargo/rustc/nextest/spt/Runner/node/link/cl with command
lines) which is how it names the CI step at that instant; then it waits for and timestamps the
REPLACEMENT daemon.

TWO INSTRUMENT FAULTS I HIT AND FIXED — both are the class I keep filing, so I am reporting them
rather than only the working end state:
(a) The first launch produced a RUNNING PROCESS THAT COULD NOT WRITE. LocalMachine execution policy
    is AllSigned, `-File` refused the script, and the process existed while the log stayed empty. I
    caught it only because I checked for the first LINE rather than for the process. Fixed with
    `-EncodedCommand`, to which policy does not apply.
(b) My verification census matched ITSELF: `Get-CimInstance ... -match 'watch-daemon'` finds every
    probe whose own command line contains that string, so I "found the watcher" four times and once
    stopped one of my own probes believing it stale. Fixed by having the watcher write watcher.pid
    and verifying from the FILE, never from a command-line census. (Disclosure for your incident
    record: that Stop-Process is the ONLY kill I have issued tonight, at ~08:17Z, against a
    powershell probe of mine, not against any spt process.)

=== 2. CENSUS — .spt/PID-KILL-CENSUS.md ===
THE SPLIT FIRST: a kill through an OWNED handle cannot hit a reused pid — Windows will not recycle
a pid while a handle is open — so 22 `child.kill()`-style sites are safe by construction and listed
once, not analysed. The population is kills that START FROM A BARE u32.
  GUARDED: servicehost.rs:651 — the reference implementation, `provably_gone` then `exe_path(pid)`
    vs the parked image via `same_image`, with a fresh post-kill read. Its comment IS the rule:
    "The pid is live. WHO is it? The image path decides — never the number."
  GUARDED: livehost.rs:1135 — kills only on a POSITIVE basename/cmdline match, else
    LEGACY_PSYCHE_SWEEP_DECLINE ... left running.
  **UNGUARDED: broker.rs:8102** — the zombie reap. `spid` is a REMEMBERED pid off the session
    record; `zombie_verdict` consults liveness BY NUMBER (`process_exists`/`is_process_alive`),
    `adapter_labeled` (a property of the RECORD, not of the live process), descendants and grace.
    **The live process's image is never read.**
  UNGUARDED (narrow): daemon.rs:3472 (`is_process_alive` only) and shellhost.rs:639 (inherits its
    caller). Guarded-by-construction: broker.rs:9736 + the test teardowns, whose pid comes from a
    live handle held in the same scope.
THE FINDING: spt-core already contains the right pattern TWICE and does not apply it at the one
production site that reaps a pid remembered across time. Fix shape: lift the image comparison into
the zombie path, or into `kill_pid_tree` itself so no caller can forget it.
AND THE HONEST PART: this does NOT explain 08:03:15Z on its own. The daemon had a live brain, so
`has_live_descendants` is true and the verdict returns false — the thing that would have saved it is
ACCIDENTAL (descendants), not deliberate (identity). It protects only while the brain is up.
LIMIT: the adapter half is INCOMPLETE. The installed dirs (PACER, alchemy, claude-spt, mobile,
omp-spt) hold only manifest.toml/record.toml. The one source I could find, omp-spt.mjs, kills owned
handles only (:989, :997). **Four of five adapters are UNCENSUSED — point me at their code.**

=== 3. BOARD PARAGRAPH — the conn-churn log defect ===
**The fleet daemon writes ~100 MB/day of stderr from brain-connection churn.** The generation-0
daemon on hfenduleam (pid 14444) accumulated **303,128,498 bytes — 303 MB — over ~72 h uptime**
(`mono_ms` 259,193,764 at its last line). Two line families dominate, both tagged
`[REQ-CONN-POISON-ATTRIBUTION]` and both `role=brain`: in the FINAL 2 MB alone there are **3,238**
`CONN_LIFECYCLE ... event=write-start` and **3,086** `CONN_LIFECYCLE ... event=transport-close
poisoned=false timed_out=false`, alongside **1,163** `NET_FAMILY_GATE: binding IPv4-only (IPv6
unreachable or disabled)`. Connection ids had reached **720,837**. The retirement path states the
cost plainly: `CONN_WRITE_RETIRED: ... organic write failure (BrokenPipe: The pipe is being closed.
(os error 232)); physical broker conn poisoned + retired, never reused (same retire behavior as
POISONED — only the failure class differs)`. So a brain conn is opened, written, broken and retired
thousands of times per 2 MB of log, each one permanently retired. The log volume is the visible
symptom; whether the churn itself is a defect or the instrumentation is merely too loud about a
normal reconnect is NOT established here, and the entry should say so — the measured claim is the
rate, the two families, the 720,837 conn ids and the never-reused sentence.

Noted you are communing across; nothing here needs an answer before you are back.
