Feat: Add a dev script for the praxis-mode live check - #1775
It starts two scratch Cortex instances side by side: one in direct mode, one in praxis mode.
Each instance runs under a scratch HOME, on ports 49700-49716.
up removes the proxy and CA variables (HTTPS_PROXY, NO_PROXY, SSL_CERT_FILE and others) from the child environment. So a caller shell that runs through the shared proxy does not leak into the scratch instance.
up refuses to start when a port of its mode already accepts a connection.
It sends interleaved latency probes to the two proxies. --noproxy '' keeps NO_PROXY from sending a probe past the proxy. Expect: stops curl's 100-continue wait on the 1 MiB body. The summary prints the count of each status code.
It samples the CPU and heap of each process, and gives CPU seconds for each pid in the summary. sample fails when it has no rows, or has praxis cortex rows but no cortex-gateway rows.
It has a selftest subcommand.
New plan: docs/superpowers/plans/2026-11-10-praxis-mode-8-live-check.md.
One line of the praxis spec (docs/superpowers/specs/2026-11-07-praxis-mode-design.md): the C7 / phase-D order.
A check with a fake cortex binary (it records its environment and answers /healthz). It failed on a3a5f13 and passes on a35eb2c:
The child gets no HTTPS_PROXY, https_proxy, SSL_CERT_FILE or NO_PROXY.
A second up direct refuses while the first one holds the ports.
sample with no rows exits 1.
curl with NO_PROXY set to the host: with --noproxy '' the request goes to the given proxy, with no Expect header. Without the flag, the proxy gets 0 bytes.
clawgenti ran plan Task 1 Step 5 (the smoke test) on a3a5f13 and it passed. Nobody has run the port_busy check, the environment strip or the codes line against real Cortex processes.
Size
Counted lines: 453 (the script, 451, and the spec, 2).
Exempt lines: 152 (the plan document).
Tasks that failed
Tasks 2, 3 and 4 of the plan are not in this PR. They are GitHub comments, not code:
[minor] sample() finds the gateway with pgrep -f "$s/bin/cortex-gateway -c $s/$m/". The plan gives the wider pgrep -f "<scratch>/bin/cortex-gateway". If the supervisor changes the gateway arguments, sample now exits 1 with a message.
[minor] probe() adds -H 'content-type: application/json'. The plan's curl line does not have it. This is harmless, and the Anthropic upstream needs it.
[minor] C3 has no limit on dropped. The Task 3 executor must report dropped and treat a value above 0 as a C3 failure.
[minor] C5 cannot pass with the method in Task 3 Step 4. That step records the Codex part of C5 as not run. C5 needs a "Status today" line, as C1 and C7 have, or a Codex frame measurement.
[minor] Spec lines 379, 462 and 479 still describe the live check as the step before the default changes. They do not name C7.
[nit] When up times out, the supervisor continues to run and supervisor.pid stays. Run down before the next up.
[nit] The probe and ttff curl calls have no --max-time. One stuck request stops the run.
[nit] C4 compares the sum of the two per-process peak RSS values. That sum can be higher than the true peak of the two processes together.
[nit] Task 3 Step 7 compares with the code that direct mode got in Step 3. When Step 3 is not run, use https://api.anthropic.com.
[nit] C2 says "For the same live session". Step 5 checks a separate run in each mode against that mode's own captures.
[nit] The codes line counts only the pairs that are kept. It does not show the codes of a dropped pair.
[nit] sample_check passes when there are praxis rows but no direct rows. C4 then has no direct row to compare with.
[nit] ttff always sends claude-opus-4-6. If the upstream does not serve that model, every pair is dropped.
[nit] build copies over cortex-gateway with cp. This fails while that binary runs. Each run uses a new scratch directory, so the risk is low.
Added a development tool that compares direct and Praxis instances for latency, streaming, and resource use in isolated environments. It includes readiness checks, measurement validation, and a self-test.
Documentation
Added criteria and a workflow for evaluating a future change to the default mode. Direct mode remains the default unless all criteria pass and a human decision is made. The next phase can begin once Praxis is stable behind setup; Praxis cannot become the default before the single-proxy criterion is met.
The plan writes the criteria for the default before the check, adds a
dev script that runs a direct and a praxis scratch Cortex side by side,
and records the result and the decision on rossoctl#1725 and rossoctl#1714.

The script starts two scratch Cortex instances, one in direct mode and
one in praxis mode, on 497xx ports under scratch HOMEs. It does not
touch the shared proxy.
Subcommands: build, up, env, probe (interleaved latency pairs), sample
(RSS, CPU and heap), ttff (time to the first SSE frame), down and
selftest. The up command refuses a config that names a 476xx port.
Part of rossoctl#1725.

A killed cortex-gateway restarts with a new pid, and its ps time starts
again at 0. The summary now adds the CPU delta of each pid. The sample
command also clears sample.tsv at the start, so rows from an earlier
run do not go into the summary. A selftest case has two pids under one
key.

The plan defines criteria and a procedure for evaluating Praxis mode as the default. A new development script builds and runs isolated direct and Praxis instances, measures latency and streaming, samples process resources, and stops the instances. The design spec updates the Phase D trigger and default-change prerequisite.

Summary
Evaluation criteria and decision process docs/superpowers/plans/2026-11-10-praxis-mode-8-live-check.md, docs/superpowers/specs/2026-11-07-praxis-mode-design.md
The plan defines seven readiness criteria, rollback conditions, issue reporting steps, and the rule that all criteria must pass before changing the default. The design spec ties Phase D to stable Praxis mode behind agentop setup --praxis and places the default change after Phase C.
Scratch instance setup and command interface scripts/dev/praxis-live-check.sh, docs/superpowers/plans/2026-11-10-praxis-mode-8-live-check.md
The script builds and starts isolated instances, checks ports and health, exports environment settings, and self-tests its helpers. The plan records the script requirements and validation gate.
Paired measurements, resource sampling, and teardown scripts/dev/praxis-live-check.sh, docs/superpowers/plans/2026-11-10-praxis-mode-8-live-check.md
The script measures paired latency and first-frame timing, samples process resources, and stops instances. The plan describes the comparison procedure and results report.

- sample: Read HeapInuse without gc=1. A forced GC every 5 s added CPU to
both cortex rows, and this pushed the C4 CPU ratio toward a pass.
- probe: Write the 1 MiB body as 513 turns of 2 KiB, not one string. The
parsers work per message, so one string measured only the byte copy.
- ttff: Give the bearer token to curl through -K on a pipe, so the token
is not in the curl argv that ps shows.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Compare each session with its own ground truth.
The two modes run separate agent tasks. Their model responses, tool calls, token counts, and timeline rows can differ even when both proxies record correctly. A direct comparison can therefore report a parity failure caused by the workload. Check each run against its own agent activity and raw captures, or replay the same traffic through both modes.

- Line 112: Update Step 4’s sampling instructions for praxis-live-check.sh so
sampling continues until both sessions and the later checks finish; if the
sampler expires first, mark C4 as not run and ensure Step 7 does not signal the
exited sampler.
- Line 112: Update Step 4’s sampler workflow so each mode has a separate
resource-measurement window covering only its required long session; exclude the
other mode, Codex tasks, ttff, agentop inspection, and fail-closed test from
those windows. Compare the per-mode workload windows for C4 rather than totals
or peaks from a sampler running across the full sequence.
- Line 112: Update the C5 measurement procedure in the long-session plan: do not
treat Codex’s median ttfbMs or Claude’s first-frame probe as evidence of
frame-by-frame delivery. Measure frame arrival throughout both streams using an
established measurement method, or mark the unmeasured portion of C5 as not run;
retain the distinction that ttfbMs measures response-header arrival.
- Line 114: Update Step 6: Fail closed (C6) so recovery is counted only when the
invalid-key probe returns its known expected upstream response, not merely any
status other than 503 or 000. Establish that expected response from the existing
probe behavior, and report other error responses separately from recovery.
- Line 76: Update the `praxis-live-check.sh probe` plan so both direct and
praxis measurements enter the latency comparison only when they receive the
expected upstream response; report other response codes separately. Use the
status check already implemented by the script to establish the expected
response rather than guessing a code.
- Line 44: The C7 rollout gate conflicts with the phase order: praxis cannot
become the default until Go forward-proxy traffic is removed, but phase C is
scheduled after phase D begins. Update the phase dependencies around C7 and
phases C-D so proxy removal and C7 validation happen before praxis can become
the default, while preserving the `--praxis` gate until C7 passes.

the gateway process was not detected, while preserving the current success
behavior for other modes.

- **C4 Resources.** On a long session (at least 40 inference turns and at least 2 subagents): the peak RSS of cortex plus cortex-gateway is at most 1.5 times the peak RSS of direct-mode cortex. Their CPU seconds summed are at most 2 times direct-mode cortex CPU seconds.
- **C5 Streaming.** Claude Code SSE and Codex (`chatgpt.com` `/backend-api/codex/responses`) stream frame by frame in praxis mode: the time to the first frame is within 100 ms of direct mode.
- **C6 Fail closed.** Kill `cortex-gateway`: the next agent request gets 503 with a `gateway_unavailable` row. The supervisor restarts the gateway, and requests succeed again within 10 s.
- **C7 One network proxy.** The conversion is complete: `cortex-gateway` is the only network proxy on the laptop, and no traffic goes through the Go forward proxy. Until C7 passes, praxis mode stays behind the `--praxis` flag (`agentop setup --praxis`), even when C1-C6 pass. Status today: fails (phases B-D of #1714 are open). Decision by Hai.

C7 requires removal of Go forward-proxy traffic before praxis becomes the default. The design removes the proxy in phase C, after phase D. Phase D starts only after praxis is the default and stable. This sequence cannot reach C7. Reconcile the criterion with the phase order.

Exclude unexpected HTTP responses from the latency comparison.
This drops only 000, so a fast 502 or 503 from the praxis proxy enters the percentiles as a valid measurement. The resulting negative delta can pass C3 while the gateway is failing. Require the expected upstream response in both modes and report other codes separately. The script currently implements this same check. (raw.githubusercontent.com)

- [ ] **Step 1: Set up.** `S=$(mktemp -d)`, `chmod 700 $S`. `build`, `up direct`, `up praxis`. In praxis `cortex.log`, find the Warn line "praxis mode: outbound plugins are off".
- [ ] **Step 2: Credentials.** Praxis mode has no `inference-router`, so the agent must call the upstream directly. Take the first server URL under `inference-router` in the real `~/.cortex/config.yaml` and its key, into `ANTHROPIC_BASE_URL` and `ANTHROPIC_AUTH_TOKEN` in the agent shell only. For Codex, copy `~/.codex/config.toml` and `~/.codex/auth.json` into each scratch HOME's `.codex/`. When a credential is missing, do the steps that do not need it, and mark the dependent criteria "not run" with the reason.
- [ ] **Step 4: Long session with subagents (C2, C4, C5).** Start `praxis-live-check.sh sample $S 3600 &` and keep its pid in `SAMPLER`. In each mode, in the shell from `eval "$(praxis-live-check.sh env <mode> $S)"`, run the same Claude Code task with `claude -p --max-turns 60` that makes at least 2 subagents (prompt: "Use two Task subagents in parallel: one lists every Go module in this repository with its go.mod path, one counts the test files under core/. Then summarize both results."), run from a fresh `git clone --depth 1` of the repository inside `$S`. Then one `codex exec` task ("List the files under scripts/dev and say what each does.") in each mode. When one Claude Code run has fewer than 40 inference turns, run the same prompt again in the same session (`claude -p --continue`) in both modes until it has 40. Then, for C5, `praxis-live-check.sh ttff $S 20 "$ANTHROPIC_BASE_URL"`. For Codex, C5 uses the median `ttfbMs` of its inference rows in each mode from the session API (Codex authenticates with an OAuth token, so `ttff` cannot call its upstream). Say in the result that `ttfbMs` measures the response headers, not the first frame.

Limit resource measurements to the comparable sessions.
The sampler runs across both agent sessions, the Codex tasks, ttff, the agentop inspection, and the fail-closed test. Its CPU totals and RSS peaks therefore do not measure only the long sessions required by C4. Collect separate workload windows for each mode and compare those windows.

Compare the two modes for C2: session count, titles, timeline rows, tool call names, subagents, tokens against the raw capture `usage` (`/v1/sessions/{id}/events/{seq}?raw=1`), cost. Record each difference. A difference that Section 5 lists as known (captured request headers, timing within 50 ms) is not a failure.
- [ ] **Step 6: Fail closed (C6).** `kill -9 "$(pgrep -f "$S/bin/cortex-gateway")"`, and at once send one request with the `probe` curl line (praxis proxy `127.0.0.1:49710`, invalid key). Expect code 503 and, in `/v1/sessions`, a row with error kind `gateway_unavailable`. Then send the same request once each 0.5 s; record the seconds from the kill to the first code other than 503 and 000. Pass when that is at most 10 s.

The first response other than 503 or 000 can be a 500 or 502, so this procedure can pass C6 while requests still fail. Require the known upstream response for the invalid-key probe, and report unexpected error responses separately.

Update Step 6: Fail closed (C6) so recovery is counted only when the invalid-key probe returns its known expected upstream response, not merely any status other than 503 or 000. Establish that expected response from the existing probe behavior, and report other error responses separately from recovery.

Check that the gateway runs before up praxis reports success.
If the gateway fails to start, Cortex can still return 200 from /healthz. up praxis then reports success without a gateway, so the live comparison can be invalid.
Check for the gateway child before reporting success. If it does not start, show the existing log tail and report a timeout.

Update the health-check loop so `up praxis` reports success only after both `/healthz` returns 200 and the gateway child is detected; continue waiting when the gateway is absent. If the checks do not succeed before the timeout, show the existing log tail and report that health or the gateway process was not detected, while preserving the current success behavior for other modes.

Summary
A useful dev tool, and the plan is clear. I ran plan Task 1 Step 5 (the smoke test the PR body lists as not run) on a3a5f13. Most of it works. One must-fix: the scratch Cortex inherits the caller's HTTPS_PROXY and SSL_CERT_FILE, so the run touches the shared proxy when the executor shell is itself routed through Cortex. There are also two suggestions, each of which can make a measurement wrong without any message.
Smoke test (Linux, as non-root):
build: pass (cortex dev, cortex-gateway dev, so the version gate passes).
up direct and up praxis: pass. The ports are 49700-49704 and 49710-49716, and nothing binds 476xx.
probe $S 5 https://api.anthropic.com: 5 pairs, 401 in both modes, dropped 0.
sample: cortex rows in both modes, cortex-gateway rows only for praxis, heap only for cortex. The pgrep patterns in sample() and down() match the argv from supervise.go:240 and :257 (<s>/bin/cortex --config <s>/<mode>/…, <s>/bin/cortex-gateway -c <s>/praxis/home/.cortex/gateway.yaml --exit-on-stdin-eof).
C6 path: after kill -9 of the gateway, every request gets 503 at once, and 401 comes back after the supervisor restarts the gateway.
down direct, down praxis and down all: no process is left under $S/bin/.
ttff with a bad token: every pair was dropped (2), exit 1.
FYI: cortex-gateway refuses to run as UID 0. In a root container, up praxis times out, and the log tail shows the refusal. This does not matter on a laptop.

must-fix: up gives the scratch Cortex the caller's whole environment, apart from HOME. The Task 3 executor is usually an agent in a shell that agentop claude-code enable or agentop exec routed through the shared proxy. That shell has HTTPS_PROXY=http://127.0.0.1:47600 and SSL_CERT_FILE=~/.cortex/ca/bundle.crt, and Cortex reads both:
The price-list download (core/cost/pricing/pricelist/pricelist.go:112) uses a plain http.Client, so it follows HTTPS_PROXY. It runs at boot and then every hour, through the shared proxy.
EnsureTrustBundle (core/tlsbridge/bundle.go:208) takes the platform roots from SSL_CERT_FILE, so the real bridge CA ends up in the scratch bundle.crt.
HTTPS_PROXY=http://127.0.0.1:49799 … up direct $S: the child's /proc/<pid>/environ has the variable, and cortex.log says pricelist: could not download the price list … proxyconnect tcp: dial tcp 127.0.0.1:49799.
SSL_CERT_FILE pointed at a bundle with a marker CA: the marker cert is in $S/direct/home/.cortex/ca/bundle.crt.
This breaks the first Global Constraint and the PR's claim "It does not touch the shared proxy", and it adds rows to the real session store. Suggested fix: clear the proxy and CA variables for the child.
env execs cortex, so $! is still the supervisor pid, and BSD env -u works on macOS. The forward proxy's own upstream transport sets no Proxy (core/listener/forwardproxy/server.go:299), so the measured traffic does not change.
The reason will be displayed to describe this comment to others. Learn more.
suggestion: --proxy does not override NO_PROXY. curl goes direct to any host listed in NO_PROXY/no_proxy, even when --proxy is given. Checked with curl 8.14.1:
NO_PROXY=api.anthropic.com curl --proxy http://127.0.0.1:1 https://api.anthropic.com/v1/messages gives 405 straight from the upstream.
With --noproxy '' added, it gives 000, because now it uses the (dead) proxy.
Corporate shells often have the router host in NO_PROXY. Then both sides of every pair go direct, both get 401 (the bundle holds the platform roots), and C3 shows a delta near 0, a pass with no proxy in the path. The ttff curl (line 305) and the plan's Task 3 Step 7 curl have the same problem. Fix: add --noproxy '' to those curl calls.
The reason will be displayed to describe this comment to others. Learn more.
suggestion: up can report success for an instance that is not running. is_up only checks that something answers on the health port. Checked: with $S direct up, up direct $S2 prints direct up: pid … while the $S2 child keeps restarting on bind: address already in use (see its cortex.log). After that, probe measures the $S binaries, and sample $S2 writes an empty sample.tsv and an empty summary, then exits 0. A leftover instance from an earlier run (a scratch dir removed without down) gives the same result.
Fix: before the start, refuse when http://127.0.0.1:$health/healthz already answers ("port in use; run down, or stop the other instance"). Also consider making sample fail when sample.tsv has no rows. Without that, a wrong pgrep pattern looks like a run with nothing to report (the gateway-pattern item in the PR body).
… samples
Fixes review:
- up removes the proxy and CA variables from the child environment.
- probe and ttff send curl through the scratch proxy also when NO_PROXY names the host.
- probe sends no Expect: 100-continue, and prints the count of each code.
- up refuses when a port of its mode already accepts a connection.
- sample fails when it has no rows, or praxis cortex rows with no gateway rows.
- The plan text agrees with the key read in Task 3, the spec line, and "Part of rossoctl#1725".

Add a time limit to each curl call that talks to a scratch instance.
probe (Line 289), ttff (Line 335) and sample_one (Line 381) call curl with no --max-time. This script exists to exercise a new proxy path, so a hung hop, gateway or stats endpoint is a plausible outcome.
If that happens, the script waits forever. A hung probe or ttff blocks the whole live run. A hung stats call in sample_one stops all sampling, and the sample trap does not run until the call returns. || true does not help, because curl never returns.
Add a bound to each call. Use a larger value for probe and ttff, which send a 1 MiB body or open a stream. Use a short value for the heap request. A timeout in probe produces code 000, which pair_ok already drops and counts.

For C2, check each mode against its own raw captures (`/v1/sessions/{id}/events/{seq}?raw=1`), because the two modes run different LLM runs: the title, the timeline rows, the tool call names and the subagent blocks agree with the captured requests and responses, the tokens are equal to the captured `usage`, and the cost is direct mode's price for those tokens. Between the two modes, compare only the shape: one session for each agent run, subagent blocks present, and zero rows with a `gateway_*` error kind. Record each difference.

- [ ] **Step 5: Check in agentop.** For each mode: `HOME=<scratch>/<mode>/home agentop --endpoint http://127.0.0.1:<session-api>` for a visual check, and read the numbers with `curl -s --noproxy '*' http://127.0.0.1:<session-api>/v1/sessions` and `/v1/sessions/{id}` (endpoint reference: `docs/session-api.md`). For C2, check each mode against its own raw captures (`/v1/sessions/{id}/events/{seq}?raw=1`), because the two modes run different LLM runs: the title, the timeline rows, the tool call names and the subagent blocks agree with the captured requests and responses, the tokens are equal to the captured `usage`, and the cost is direct mode's price for those tokens. Between the two modes, compare only the shape: one session for each agent run, subagent blocks present, and zero rows with a `gateway_*` error kind. Record each difference.
- [ ] **Step 6: Resources (C4).** `kill -TERM "$SAMPLER"; wait "$SAMPLER"`. Keep `$S/sample-summary.txt`. Copy it out of `$S` (into the Task 4 comment body file in a second `mktemp -d`) before Step 8. Stop the sampler before Step 7: the gateway restart in Step 7 occurs only in praxis mode.
- [ ] **Step 7: Fail closed (C6).** `kill -9 "$(pgrep -f "$S/bin/cortex-gateway")"`, and at once send one request with the `probe` curl line (praxis proxy `127.0.0.1:49710`, invalid key). Expect code 503 and, in `/v1/sessions`, a row with error kind `gateway_unavailable`. Then send the same request once each 0.5 s; record the seconds from the kill to the first code that is the same as the code direct mode got in Step 3 (`$S/probe.tsv`). Record each other code in the result. Pass when that time is at most 10 s.

Read the event row from a session detail endpoint.
/v1/sessions lists session summaries; it does not return event rows. This step cannot verify gateway_unavailable from that response. Find the relevant session and inspect its events instead. (raw.githubusercontent.com)

Update Step 7 to locate the relevant session from the `/v1/sessions` summaries, then inspect that session’s detail endpoint to verify an event row with error kind `gateway_unavailable`; keep the existing request sequence and timing checks unchanged.

- [ ] **Step 1:** Post one comment on #1725: a table with one row per criterion C1-C7 (measured value, threshold, pass / fail / not run), the probe and sample summaries, the agent and Claude Code / Codex versions, the date, and every C2 difference.
- [ ] **Step 2: Decide.** Rule: the default changes only when C1-C7 all pass. Expected result: C1 fails by design, so the decision is "direct mode stays the default; praxis mode stays opt-in (`agentop setup --praxis`)". Write the decision and the criteria that block it.
- [ ] **Step 3:** Post a short comment on #1714 with the decision and a link to the result comment. Update the tracker's phase A row when the body has one for step 8.
- [ ] **Step 4:** Close #1725 with a link to the result comment. The PR from Task 1 says `Part of #1725`, so its merge does not close the issue.

Keep the issue open when the live check was not run.
Task 3 permits credential-dependent checks to be marked “not run.” This step still closes #1725, even if neither agent session ran. Close it only after the required live checks are complete, or explicitly track the remaining work.

Summary
The fixes for the previous review are in, and they work on a35eb2c. I checked the script with stub cortex / cortex-gateway binaries and stub proxies on Linux:
Environment strip: with HTTPS_PROXY, https_proxy, ALL_PROXY, NO_PROXY, no_proxy and SSL_CERT_FILE set in the caller shell, the child sees none of them, and HOME is the scratch home. A grep of cmd/cortex and core finds no other proxy or CA variable that Cortex reads (only SSL_CERT_FILE / SSL_CERT_DIR in tlsbridge/bundle.go).
port_busy: a second up direct stops at the pid check. With the pid file removed, it stops at port 49704 is in use, exit 1.
probe: with the target host in NO_PROXY, every request still reaches the given proxy. The proxy gets no Expect header and the full 1,066,851-byte body. A praxis side that answers 503 drops every pair (every pair was dropped (3), exit 1).
ttff: the bearer token gets to the upstream through -K <(…). The first-data: timing works.
sample: no rows gives exit 1. SIGTERM writes the summary and gives exit 0. Both modes give the expected cortex / cortex-gateway rows. down all cleans up.
bash -n, shellcheck 0.11 (plain, not --severity=error) and selftest pass.
There are two inline suggestions about measurements that can be wrong with no message. Neither blocks the merge.
One thing outside the code: the PR body says "For this reason, this PR is a draft", but the PR is not marked as a draft. If you want to keep it open until Tasks 2-4 are done, mark it as a draft. If not, change the body.

suggestion: sample_check passes when the file has praxis rows but no direct cortex rows. The PR body lists this as a known nit. For C4 it is the bad case: the ratio has no denominator, but sample still exits 0. I checked with a stub where the direct child does not match the pgrep pattern. sample wrote only praxis rows, printed only praxis lines, and exited 0. The Task 3 executor then has to see that one line is missing.
The file always samples both modes, so it is enough to also require a direct cortex row:
awk '$2 == "direct" && $3 == "cortex" {d = 1} END {exit !d}'"$1"||
{ echo"no direct cortex was sampled">&2;return 1; }
Then the selftest case at line 125 (direct only) keeps passing, and a new praxis only case should fail.

nit: ps -o time= has a resolution of 1 s on Linux (procps prints 00:00:00). On macOS it gives hundredths (0:01.50). So on Linux, cpu_s for each pid moves in whole seconds. A short sample, or a process that uses little CPU (the gateway on a light run), can show cpu_s 0.00, or a C4 ratio that is far from the real value. On a long Task 3 session this matters less. But if the check runs on Linux, read utime + stime from /proc/<pid>/stat (in clock ticks, getconf CLK_TCK). Or the plan can say that C4 CPU is measured on macOS only.
