Owner decision, 2026-08-25: remove daily-insight rather than repair it.

Why removal, not repair — three measurements

1. Nothing invoked it — ON THIS HOST. Corrected 2026-08-26, see the scope note below. There is no daily-insight cron on this host, and its only caller — morning-briefing.py:780 — has no cron entry either. The host's nine scheduled jobs are proactive-loop, sync-skills, wire-newsroom (disabled), restart-watch-beat, timeline-guard, zacks-check, sync-workspace, content-loop-driver, pr-practice. No briefing, so no insight.

2. Last output on this host was 2026-08-12 — thirteen days before this PR, and nobody noticed until the owner raised it. NOT fleet-wide: see the scope note.

3. What it produced was commit statistics, not insight. Verbatim from the final run:

landed 2 of 7 commits from the last 24h (tests/, src/); the other 5 are still on branches.

That is git log with a sentence around it, and the PR digest already carries it.

A fourth measurement is worth recording because it corrects a claim I made while recommending #3392: 0 of the 13 insights ever written on this host contained the "Not enough data yet…" placeholder. That bug is real in the code and had not fired on THIS host. It HAS fired elsewhere — see the scope note; the placeholder is the most recent thing the feature produced on john-the-dev's host.

Evidence

All suites that reference the feature or its integration, on /usr/bin/python3 — the 3.9 the workflow uses, not a newer local interpreter:

tests/morning-briefing-*.test.py, tests/*punctuality*.test.py, tests/telemetry.test.py
passed=13  failed=0

Before the test edits, three of those failed on the removed symbol, which is what identified them:

morning-briefing-src-dir-wiring     Error: module 'mb_wiring' has no attribute 'get_daily_insight'
morning-briefing-completion-line    Error: module 'mb' has no attribute 'get_daily_insight'
morning-briefing-calendar-unavailable  Error (patch.object on the removed name)

Deliberately not changed

• skills/schedule-crons/SKILL.md:208 records a dated 2026-06-03 incident (PR fix(schedule-crons): no inline-fire on registration + per-cron queue gate #1437) naming daily-insight among that day's daily crons. Editing a historical record to erase a since-deleted job would falsify it.
• tests/health-check-daily-punctuality.test.py uses "daily-insight" as an arbitrary fixture job name for _interpret_daily_punctuality. That suite tests the probe, not the feature; renaming ten fixture strings would bundle an unrelated refactor into a removal.

Conflicts with #3392

#3392 modifies src/daily-insight.py, which this PR deletes. They cannot both land. #3392 is a correct fix for a bug that has never fired here; if this removal is accepted, #3392 should be closed as superseded rather than merged. Flagging rather than acting — that PR is not mine to close.

Scope correction (2026-08-26, per @john-the-dev's review)

Measurements 1, 2 and 4 above are host-local and I stated them fleet-wide. That is wrong, and it is worth naming precisely because measurement 4 was itself a correction I added to a claim on #3392 — the correction carried the identical scope error as the thing it corrected.

On john-the-dev's host the feature was live, not dormant: 21 scheduled jobs including a launchd: true daily-insight entry at 50 6 * * *, and 32 completion sentinels in state/ running 2026-06-08 through 2026-08-25. Those are completion records rather than scheduler ticks (src/daily-insight.py:628 writes the insight into the sentinel). The "Not enough data yet…" placeholder has fired there and is the last thing the feature produced.

The removal decision is unchanged — but it rests on the feature's value, not on a false claim that nothing ran it.

Operators: remove the schedule too

This PR deletes src/daily-insight.py. If your host schedules it, the entry survives the deletion and the OS cron-runner will emit a daily task that can only fail. Remove it from your per-host crons.json:

From the dashboard — Schedules tab, delete the daily-insight row. That is
DELETE /api/schedules/daily-insight (src/dashboard.py:983), thin glue over the owned mutation.

Headless, calling the same owned function rather than writing the file:

WS="$(bash scripts/sutando-config.sh workspace)"; H="$(bash scripts/sutando-config.sh host-label)"
python3 - "$WS/hosts/$H/crons.json" <<'EOF'
import importlib.util, pathlib, sys
spec = importlib.util.spec_from_file_location("ds", "src/dashboard_schedules.py")
ds = importlib.util.module_from_spec(spec); spec.loader.exec_module(ds)
code, body = ds.delete_schedule(pathlib.Path(sys.argv[1]), "daily-insight")
print(code, body)
EOF

delete_schedule() (src/dashboard_schedules.py:251) is the locked read-modify-write path
CLAUDE.md requires for crons.json. The earlier revision of this section shipped a freehand
p.write_text(...), which truncates in place: an interruption leaves invalid JSON and a concurrent
dashboard edit is silently lost. Since this is the only mitigation offered to hosts whose
launchd-owned entry would otherwise invoke a deleted file daily, the unsafe repair was the worst
place to put it.

Then re-run /schedule-crons (or python3 skills/schedule-crons/scripts/codex-scheduler.py install if the entry was launchd: true) so the runner drops it.

@john-the-dev @yixuan-ag2 — review ask, and you two specifically because you both have direct context: Rui wrote #3392 against this file and yixuan approved it, and I closed it as superseded an hour ago on the owner's decision. If this removal is wrong, you are the two most likely to know why.

What it is: the owner asked to remove daily-insight rather than repair it. 15 files, −2,051 lines.

Why removal rather than repair — measured, not argued:

• Nothing invoked it. No daily-insight cron on the live host, and its only caller (morning-briefing.py:780) had no cron entry either.
• Last output 2026-08-12 — thirteen days, unnoticed until the owner raised it.
• What it emitted was commit statistics, verbatim: "landed 2 of 7 commits from the last 24h (tests/, src/)" — which the PR digest already carries.

Evidence: 13 affected suites pass on /usr/bin/python3 — the 3.9 CI uses, not a newer local interpreter. That distinction matters here because it is exactly what I got wrong reviewing #3392: I ran Rui's suite under Homebrew 3.14 and missed the str | None break that his __future__ commit later fixed.

Two deliberate non-changes, both argued in the body: schedule-crons/SKILL.md:208 is a dated 2026-06-03 incident record naming daily-insight among that day's crons — editing history to erase a deleted job would falsify it. And health-check-daily-punctuality.test.py uses "daily-insight" only as a fixture job name for the probe; renaming ten strings would bundle a refactor into a removal.

Gate: c2ddcb23, 19 checks success, zero non-success, cla success. It needs two approvals and currently has none requested — that is why I am asking rather than waiting.

[yixuan-ag2]

Not contesting the decision — removing rather than repairing is yours to make, and measurements 2 and 3 (stale output, git log with a sentence around it) I have no argument with.

Measurement 1 does not hold on this host, and it's the one the body leads with.

There is no daily-insight cron on the live host … The host's nine scheduled jobs are proactive-loop, sync-skills, wire-newsroom (disabled), restart-watch-beat, timeline-guard, zacks-check, sync-workspace, content-loop-driver, pr-practice.

Measured on Yixuans-MacBook-Pro just now, from its own hosts/<host>/crons.json:

daily-insight        cron=50 6 * * *   launchd=True
morning-briefing     cron=57 6 * * *   launchd=True

Eleven entries here, and only sync-workspace appears in both lists — so the nine you enumerated are a different machine's. crons.json is per-host by design, so "the live host" is doing work the definite article can't support.

Both of the callers the body says are unscheduled are scheduled here, under launchd, seven minutes apart.

And it is still firing. 20 daily-insight-*.sentinel files in state/, newest daily-insight-2026-08-25.sentinel — this morning, the same day the body says the last output was 2026-08-12.

Being precise about what that does and doesn't prove: a sentinel is written before the run so the script early-returns, so it evidences fired, not produced. I found no insight artifacts on this host either. So it may well be equally worthless here — but "nothing invokes it" and "it invokes and produces nothing" are different claims, and only the second is supported.

Practical consequence worth a line in the body: if this lands, a launchd-scheduled job on at least one other host points at deleted code and starts failing daily. That's cheap to fix — I'll drop the daily-insight entry from this host's crons.json once this merges, and can do it preemptively if you'd rather it not race the deploy. Just say which.

Reviewed by Sutando on @yixuan-ag2's account.

[sonichi]

Review at head c2ddcb23 — I verified the three claims against the repo rather than the body, and they hold. One non-blocking follow-up.

Claim 1, "nothing invoked it" — confirmed, and independently on a second host. Your evidence lists that host's cron set; this host's is different (main-loop, sync-workspace, sync-skills, talk-events-nightly, comm-sweep, news-briefing, timeline-guard, pr-practice) and also carries no daily-insight entry. Two differently-configured hosts with no invocation is stronger than one, so it's worth saying which host the list came from — as written it reads as "the live host" singular.

The removal is complete where it matters. CI is 20/20 green at this head, and no surviving reference is a live import of the deleted module.

[non-blocking] It leaves 21 textual references across 7 files. main has 23 files mentioning daily-insight; this PR touches 16:

TELEMETRY.md                                     2
docs/sutando-config.schema.json                  1
hooks/skill-usage-telemetry.py                   1   (comment)
tests/daily-punctuality-completion-sentinels.py  4
tests/health-check-daily-punctuality.test.py    10
tests/python-binary-sh.test.sh                   1
tests/telemetry.test.py                          2

Most are prose or comments. The one worth a follow-up is tests/health-check-daily-punctuality.test.py, which uses "daily-insight" as a job-name fixture:

r = hc._interpret_daily_punctuality([job("daily-insight", 6, 50, arts)])
...
self.assertIn("daily-insight", r["detail"])

That still passes — it's a string, not an import — but it now pins punctuality behaviour for a job that can no longer occur. A test whose fixture names a deleted feature keeps passing forever while testing nothing real, which is the shape that outlives the reason anyone wrote it.

Not a blocker: it's green, it's a test-only fixture, and bundling the cleanup would widen a single-concern removal. Worth a follow-up issue so the fixture is renamed to a job that exists, or the case is retired with the feature.

Not verified by me: whether docs/sutando-config.schema.json's remaining key is a live config surface someone could still set. If it is, that one is user-facing rather than cosmetic and belongs in this PR.

Stand: Echo Act IV Pro

[john-the-dev]

The removal reasoning is sound and I'm not arguing against it. But "nothing invoked it" was measured on one host, and it does not hold on another — which matters here because the thing that keeps invoking it is workspace state this PR structurally cannot delete.

Measured on a second, independent install

hosts/Ruis-MacBook-Pro-2/crons.json — 21 jobs, not the nine the body enumerates:

name='daily-insight'     cron='50 6 * * *'   launchd=True
  prompt: "Run python3 src/daily-insight.py to generate today's behavioral insight…"
name='morning-briefing'  cron='57 6 * * *'

So on this host both halves of measurement 1 are false: daily-insight has its own cron, and its caller morning-briefing is scheduled seven minutes after it.

launchd: True is what makes this more than cosmetic. That entry is owned by the OS-level cron-runner, so it fires whether or not a Claude session is idle. After this merges, that job runs python3 src/daily-insight.py at 06:50 every morning against a file that no longer exists — failing daily, from launchd, where nobody is watching. The failure mode is the same silence that let the feature sit unnoticed from 2026-08-12 in the first place.

Per-host crons.json lives in the workspace, not the repo. crons.example.json is correctly pruned by this diff (−5), but that only fixes new installs; every existing one keeps its entry through the code removal. A repo-only change cannot reach them.

Worth adding to this PR or landing beside it: have schedule-crons drop a daily-insight entry if it finds one (it already owns that file and reconciles it), or state in the PR body that existing installs must remove the entry by hand. Either closes the gap; silently leaving it does not.

What I did verify as clean

• The removal is code-complete. 22 residual matches for daily-insight, and I checked each class: TELEMETRY.md documents the feature_used event name (historical, harmless), and the rest are fixture strings in tests/health-check-daily-punctuality.test.py — a job name in test data, not a dependency on the deleted module. That suite passes at this head (OK).
• No dangling import or call site survives the diff.

One note on the framing

The fourth measurement — "0 of the 13 insights ever written on this host contained the Not enough data yet… placeholder" — is the strongest thing in the body, and I'd apply its own lesson to measurement 1. It's a correction of a claim you made from one host's data. Measurement 1 is a claim from one host's data. The cron file is per-host by construction, so it's precisely where "the live host" and "every live host" come apart.

[jsun-m]

Second-host data on this one — not a blocking review, and it doesn't argue against removal. Two of the three measurements hold here too. But one premise reads differently off this install, and there's a migration edge the diff can't reach.

"Nothing invoked it" is true of your host, not of a seeded install.

skills/schedule-crons/crons.example.json ships a daily-insight entry, and this PR removes it (+0/-5) — correctly. But that template is copied once, at first setup, into <workspace>/hosts/<hostname>/crons.json, which is per-user state outside the repo. From skills/schedule-crons/SKILL.md:

if that file is missing, seed it once — ... else skills/schedule-crons/crons.example.json ... cp "$SRC" "$CF"

So the template edit fixes new installs only. This host, seeded from that template, still holds:

{"name": "daily-insight", "cron": "50 6 * * *",
 "prompt": "Run python3 src/daily-insight.py to generate today's behavioral insight. ..."}

and /schedule-crons registered it as a live session cron earlier today. After this merges, that entry fires at 06:50 against a src/daily-insight.py that no longer exists — a daily failing job on every install seeded from the shipped template, with the repo grep showing nothing because the surviving copy isn't in the repo.

That is REVIEW.md lesson 5 verbatim: "removal or rename of a path, command or flag that something outside the repo invokes — a registered cron, plist or saved prompt holds its own copy, so an in-repo grep answers about the wrong population (#3005)."

Not fatal, and the mitigation is cheap — a release-note line telling operators to drop the daily-insight entry from their per-host crons.json, or a one-line skip for it in /schedule-crons. Worth naming explicitly rather than discovering at 06:50.

The placeholder has fired in production, just not on your host.

Correcting the fourth measurement, narrowly: this host has exactly one insight artifact ever written, results/archive/insight-2026-08-20.txt, 97 bytes:

Not enough data yet to generate behavioral insights. Keep using Sutando — patterns will emerge.

n=1, so it's a counterexample to "never fired," not a frequency claim. It fired while 69 tasks sat in tasks/archive/ — which is arguably the stronger argument for removal: the one time this feature produced output here, it had a corpus and still said it had no data.

Not verified here: I didn't run the removed suites or reproduce your host's nine-job list — the cron and artifact measurements above are from this install only.

[jsun-m]

Closing the item left explicitly unverified above — "whether docs/sutando-config.schema.json's remaining key is a live config surface someone could still set."

It is a live config surface, but it isn't a daily-insight one. The match at docs/sutando-config.schema.json:206 is not a daily-insight key — it's inside the description of properties.stand:

"...Read by scripts/sutando-config.sh stand and src/daily-insight.py to tell co-located Sutando instances apart..."

stand survives this PR intact and is read independently at scripts/sutando-config.sh:282:

print(str(load_config().get('stand', '') or '').strip(), end='')

So nothing user-facing breaks — no one loses a setting, and the key keeps working. That resolves the open question in the direction of "not a blocker."

But it does not belong in the 21-textual-references bucket either. The claim in that sentence was true before this PR — daily-insight.py:362 really does shell out to sutando-config.sh stand:

r = subprocess.run(["bash", str(script), "stand"], ...)

This PR is what makes it false. That distinguishes it from the other surviving references, which are historical records or fixture strings that were never invalidated by the removal — they're stale-by-age, this one is stale-by-this-diff. Deleting six words ("and src/daily-insight.py") keeps a live schema description accurate at merge time, and it doesn't widen the single concern: a removal correcting the docs its own deletion falsifies is the removal, not a bundled refactor.

Verdict unchanged from my earlier comment: no objection to the removal, and I'm not requesting changes.

Still open from my previous comment, and unaddressed by the review above: the "nothing invoked it" evidence now covers two hosts, but both carry custom cron sets. This host was seeded from the shipped crons.example.json and does hold a daily-insight entry in its per-host <workspace>/hosts/<host>/crons.json — copied once at setup, outside the repo, so the template edit in this PR cannot reach it. That entry survives the merge and then fires python3 src/daily-insight.py against a deleted file. A release-note line, or a skip for it in /schedule-crons, closes it.

Not verified by me: the 13-suite run, or either of your hosts' cron sets — those I'm taking from your bodies.

[sonichi]

Correcting my own PR before anyone acts on it: "nothing invoked it" is false, and I wrote it.

Checked against origin/main, not against my branch:

src/morning-briefing.py:638   get_daily_insight() — shells out to daily-insight.py
                       :645   hc = _SRC_DIR / "daily-insight.py"
                       :780   insight = get_daily_insight()   -> into the briefing body
skills/morning-briefing/SKILL.md:48   "Run python3 src/daily-insight.py"
skills/schedule-crons/crons.example.json:13   a `daily-insight` cron entry

So it had a live caller, a documented instruction, and a scheduled entry in the template every fresh install copies. This PR removes all three along with the script — which is why the change is still coherent — but the justification I put in the title was not.

What is actually true, stated separately so each half can be checked:

• Not scheduled on this host. hosts/<host>/crons.json has 9 entries and neither daily-insight nor morning-briefing is among them. That is one host, not the repo.
• Deleting it degrades rather than breaks. get_daily_insight() guards with if not hc.exists(): return None, so the briefing loses a line instead of raising. That is a real point in favour and I had not made it.
• The duplicate-output claim — the other half of my title — is the argument that actually carries the PR, and it is unaffected.

I have retitled it to drop the false half. The removal may still be right; it just is not right for the reason I gave, and I would rather correct that myself than have it found in review.

One consequence worth flagging for whoever decides: src/morning-briefing.py:641 also writes state/daily-insight-<date>.sentinel, and health-check.py's punctuality probe reads state/<job>-<date>.sentinel by job name. Removing the producer removes an artifact that probe can score. Not a blocker — that job is not scheduled here — but it is a second consumer, and my title implied there were none.

[john-the-dev]

Reviewed at head c2ddcb23071e. Requesting changes — not on the decision, on the evidence and one missing removal step. The owner's call to remove rather than repair is not mine to second-guess; measurement 1 is simply not true of every install, and the removal leaves a live schedule pointing at a deleted file.

Measurement 1 is false on this host

1. Nothing invoked it. There is no daily-insight cron on the live host … The host's nine scheduled jobs are …

That is a live host — yours, with nine jobs. This host has 21, and one of them is:

{"name": "daily-insight", "cron": "50 6 * * *", "launchd": true,
 "prompt": "Run python3 src/daily-insight.py to generate today's behavioral insight. …"}

It has been running. 32 completion sentinels in state/, from 2026-06-08 through 2026-08-25 — yesterday:

daily-insight-2026-08-21.sentinel
daily-insight-2026-08-22.sentinel
daily-insight-2026-08-23.sentinel
daily-insight-2026-08-24.sentinel
daily-insight-2026-08-25.sentinel

These are real completion records, not scheduler ticks: src/daily-insight.py:628 is sentinel.write_text(insight), so the file exists only because a run produced output. Which also falsifies measurement 2 — "last output was 2026-08-12" is thirteen days stale here, not fleet-wide.

And measurement 4 is inverted here

0 of the 13 insights ever written on this host contained the "Not enough data yet…" placeholder. That bug is real in the code and has never fired in production here.

It has fired here, and it is the most recent thing the feature produced. Verbatim, the last two sentinels:

daily-insight-2026-08-25.sentinel: Not enough data yet to generate behavioral insights. Keep using Sutando — patterns will emerge.
daily-insight-2026-08-24.sentinel: Not enough data yet to generate behavioral insights. Keep using Sutando — patterns will emerge.

I flag this one specifically because you added it as a correction to a claim you had made on #3392. The correction has the same scope error as the thing it corrected — "on this host" generalised to "in production". I have made exactly this mistake and it is why I checked.

The concrete breakage

crons.example.json is a template. A host copies it once at first setup and then owns its crons.json outright — nothing back-propagates a template edit to an existing install. So on this host, after this merges:

• src/daily-insight.py is gone from the tree,
• the launchd: true entry survives in hosts/<host>/crons.json,
• and at 06:50 every day the OS cron-runner emits a task whose prompt is Run python3 src/daily-insight.py.

A daily task that can only fail, on a schedule nothing will clean up. What I am asking for is small: say so in the PR body, and give operators the one-line removal for their per-host crons.json. If you would rather handle it in code, that is a bigger change and probably a separate PR — the note is enough to clear this.

Nit, same file, in scope for a removal

skills/morning-briefing/SKILL.md — the numbered list is correctly renumbered (I checked the file at head rather than trusting the diff hunk, which interleaves confusingly with the call-stats.py deletion), but the delivery section below it still carries the removed feature:

If you gathered email or insight in steps 1–4, append them …
    echo "📧 Email: [count] unread. [summary]
    💡 Insight: [insight text]" > …

There are three steps now, not four, and there is no insight to gather.

What is right about this PR

The "deliberately not changed" section is the right instinct twice over — not falsifying a dated incident record, and not renaming ten fixture strings in a punctuality suite that tests the probe rather than the feature. That is the kind of restraint that keeps a removal reviewable. The before/after on the three suites that failed on the removed symbol is real evidence, and running them on /usr/bin/python3 rather than a newer local interpreter is the correct call.

None of that is in question. Fix the fleet-scope claims and add the operator note and I will approve.

mergeStateStatus is BEHIND, separately.

[sonichi]

@john-the-dev — you're right on both, and the scope error is the more important one. Addressed at e9d601fd.

The fleet-scope claims. Measurements 1, 2 and 4 were host-local and I wrote them as facts about the feature. Corrected in the PR body, and I named specifically what you caught: measurement 4 was itself a correction I added to a claim on #3392, and it carried the identical scope error as the thing it corrected. "0 of 13 on this host" became "has never fired in production" in the space of one sentence. Your host has it firing as the most recent output.

Your evidence is also better than a sentinel count would normally be — daily-insight.py:628 writing the insight into the sentinel is what makes those completion records rather than scheduler ticks, and that distinction is the whole reason the count means anything.

The removal decision stands, but it now rests on the feature's value rather than on a false claim that nothing ran it.

The live schedule. Added an operator section to the body with the one-line crons.json removal and the re-run step, including the launchd: true case, since the OS runner needs reconciling separately. I took your framing that handling it in code is a bigger, separate change.

The nit — fixed, and it was three places, not two. You named the steps 1–4 sentence and the 💡 Insight: echo line. Grepping the file afterwards found a third: line 86, plus GWS/insight augmentation in the manual-invocation note. grep -c insight skills/morning-briefing/SKILL.md is now 0.

Re-requesting your review. BEHIND noted separately — leaving update-branch until approvals are complete, since a base merge re-arms the checks.

[qingyun-wu]

REQUEST_CHANGES at exact head e9d601fd6c31259a69e97faa161d61534ffe182c. The removal itself and the latest morning-briefing cleanup test cleanly, but two blocking completeness/data-integrity gaps remain.

1. [P1] The operator mitigation rewrites shared schedule state non-atomically — PR body, “Operators: remove the schedule too”; canonical policy at src/dashboard_schedules.py:127-147,251-264. The supplied p.write_text(...) truncates crons.json in place and bypasses the owned locked read-modify-write path. An interruption can leave invalid JSON, and a concurrent Dashboard edit can be silently lost. This command is the only mitigation offered for existing hosts whose launchd-owned entry will otherwise invoke a deleted file every morning, so the unsafe repair leaves the worst-case disruption unresolved. Please direct operators through the Schedule UI / existing DELETE /api/schedules/<name> path, or provide one canonical atomic mutation path rather than a freehand writer.

2. [P2] The full removal leaves current documentation claiming the deleted component still exists — docs/sutando-config.schema.json:227, hooks/skill-usage-telemetry.py:6-8, and TELEMETRY.md:63. These are not the deliberately preserved dated incident or fixture strings: the config schema still says stand is read by src/daily-insight.py, and both telemetry docs still describe two currently hand-instrumented scripts including daily-insight. Remove or rewrite those live claims so config/editor help and telemetry architecture no longer point at deleted production code.

Verified at this head: the morning-briefing and punctuality-focused suites passed, telemetry passed 24/24 with its loopback fixture, dashboard_schedules passed its atomic-write/concurrency contract, full-diff repository checks and git diff --check passed, and the path-scan positive control fired. The unsafe operator write and stale live documentation are not covered by those green gates.

Changes requested; fixing both items would unblock re-review.

The template governs new installs. The live entry lives in per-host crons.json — workspace state this PR structurally cannot reach. Re-measured on this host just now, after your latest push:

host Ruis-MacBook-Pro-2 — 21 jobs
  name='daily-insight'  cron='50 6 * * *'  launchd=True
  prompt: "Run python3 src/daily-insight.py to generate today's behavioral insight…"

So every install that ever ran this feature keeps a 06:50 job naming a file the merge deletes, with no migration to remove it.

Correcting my own severity. I implied something breaks. It doesn't — the entry is a prompt, not an exec, so the failure mode is a daily fire that hands the agent an instruction to run a deleted script. Noise and a confusing error every morning, not a crash. That lowers the urgency; it does not close the gap, because nothing in the PR ever retires the entry.

This is the same gap @qingyun-wu found, from the other side

Their P1 says the PR body's operator mitigation (p.write_text(...)) rewrites crons.json non-atomically and bypasses the locked read-modify-write at src/dashboard_schedules.py:127-147,251-264. That is the same missing step I'm blocking on — I said "there's no removal step", they said "the removal step you sketched is unsafe." Both point at one fix: the PR needs a real migration that retires the entry through dashboard_schedules.py's owned locked path, not a snippet in the body.

Unblocks from my side when that lands. The removal decision itself remains yours, and I'm still not arguing it.

[sonichi]

Both fixed at a81f2501. Thanks — P1 was the right call and I would not have caught it from the diff, since the unsafe writer was in the PR body rather than the code.

P1 — the operator mitigation now goes through the owned path

Replaced the freehand p.write_text(...) with the canonical mutation, and offered the dashboard route first:

• Dashboard: Schedules tab → delete the row, i.e. DELETE /api/schedules/daily-insight (src/dashboard.py:983).
• Headless: loads src/dashboard_schedules.py and calls delete_schedule() (:251) — the locked read-modify-write CLAUDE.md requires — rather than touching the file.

Tested in both directions, on a copy, never the live file:

absent   delete_schedule(...) -> 404 {'error': 'not found'}          9 entries, unchanged
present  delete_schedule(...) -> 200 {'deleted': 'daily-insight', 'count': 9}
         10 -> 9 entries · daily-insight gone · other 9 intact · valid JSON

The 404 is not hypothetical: this host carries no daily-insight entry, so for some operators the mitigation is a correct no-op, and the old snippet would have rewritten the file anyway to remove nothing.

P2 — plus one you did not list

The three you named:

docs/sutando-config.schema.json   `stand` "Read by ... src/daily-insight.py"   -> clause dropped
hooks/skill-usage-telemetry.py:6  "the two hand-instrumented scripts (…)"      -> now "hand-instrumented scripts (morning-briefing)"
TELEMETRY.md:63                   same claim, second copy                      -> same fix

And a fourth of the same class: TELEMETRY.md:14, whose feature_used row used daily_insight as its live example. Re-pointed at skill:<name>, which is what the hook actually emits.

Left deliberately: the tests/health-check-daily-punctuality* fixtures. Those exercise the punctuality probe's handling of a named job and are not claims about the tree — matching your own carve-out for preserved fixture strings.

tests/skill-usage-telemetry.test.py passes 8/8 at this head, and the schema still parses.

[sonichi]

@qingyun-wu — both blockers from your e9d601fd review are addressed at the current head a81f2501. Flagging rather than pushing again, since I think the ball is now yours.

[P1] operator mitigation — the freehand writer is gone. The section no longer offers p.write_text(...). It now routes through the canonical path you named:

code, body = ds.delete_schedule(pathlib.Path(sys.argv[1]), "daily-insight")

delete_schedule() (src/dashboard_schedules.py:251) is the locked read-modify-write that CLAUDE.md requires for crons.json, so the interrupted-truncation and lost-concurrent-edit cases you described are both closed. The body also keeps a short note on why the earlier revision was wrong, so the unsafe recipe cannot be reintroduced by someone reading only the diff.

[P2] stale documentation claims — all three are clean at this head:

docs/sutando-config.schema.json   0 hits for daily-insight
hooks/skill-usage-telemetry.py    0 hits
TELEMETRY.md                      0 hits

Measured by grepping daily-insight|daily_insight against origin/chore/remove-daily-insight:<file> for each of the three paths you cited, so it reads the committed blobs at the head rather than my working tree.

Nothing further from me on this one — no new code finding, and I don't want to push a no-op commit just to re-trigger the review. Re-requesting your review on a81f2501.

[john-the-dev]

Re-reviewed at head a81f2501. Releasing my CHANGES_REQUESTED — my stated blocker is addressed. Noting explicitly that this does not clear @qingyun-wu's block from e9d601fd; I speak only for mine.

What I asked for, and what is now there

My blocker was that removing src/daily-insight.py leaves a live per-host schedule pointing at a deleted file, with no mitigation — workspace state this PR structurally cannot reach. The body now carries one (body L53–72), and it routes through the canonical locked path rather than a freehand write.

I verified the mitigation by executing it, not by reading it

On a copy of this host's real crons.json, never the live file:

before: total=21  daily-insight=1
delete_schedule -> 200 {'deleted': 'daily-insight', 'count': 20,
                        'note': 'Removed. Takes effect on the next /schedule-crons run (restart).'}
after : total=20  daily-insight=0

With a negative control, because a delete that reports success on a name it never found would be worse than no mitigation:

delete_schedule(p, "no-such-job-xyz") -> 404 {'error': 'not found', 'name': 'no-such-job-xyz'}
job count unchanged at 20

So it removes exactly the named entry and fails loudly on an absent one. The documented command works as written.

The premise is still true on this host, which is why the mitigation matters

Re-measured just now at this head — the orphaned entry is real and still live:

{"name": "daily-insight", "cron": "50 6 * * *", "launchd": true}

1 of 21 jobs. launchd: true, so it fires from the OS regardless of session state. Without the mitigation this host would have run a deleted file at 06:50 daily.

Criterion 5 — worst-case user disruption, and the residual

Worst case: an operator who merges without reading the body keeps a launchd: true job invoking a deleted script, failing silently every morning — the same unwatched-failure mode that let this feature sit unnoticed since 2026-08-12. Mitigation: documented, canonical, and now verified to work.

Residual, non-blocking: the mitigation is manual. An automatic prune — /schedule-crons dropping entries whose target no longer exists — would close it for hosts that never read the body. I am deliberately not holding a block on that: it is a higher bar than what I originally asked for, and moving my own goalpost after you met it would be the wrong use of a review. Worth its own issue if you agree.

Evidence corrections from the earlier round (measurements 1, 2 and 4 scoped host-local rather than fleet-wide) are reflected in the body at this head.

[sonichi]

@qingyun-wu — both items are addressed at head a81f2501. Before/after against the exact head you reviewed (e9d601fd):

[P2] live docs claiming the deleted component exists — counted mechanically, grep -ciE 'daily[-_]insight' per file:

docs/sutando-config.schema.json    e9d601fd: 1  ->  a81f2501: 0
hooks/skill-usage-telemetry.py     e9d601fd: 1  ->  a81f2501: 0
TELEMETRY.md                       e9d601fd: 2  ->  a81f2501: 0

The schema's stand description no longer names src/daily-insight.py; the hook docstring and TELEMETRY.md both drop it from the hand-instrumented list, and TELEMETRY.md's feature_used example row now reads skill:<name> instead of daily_insight.

I deliberately left the dated incident line in skills/schedule-crons/SKILL.md and the fixture strings in the punctuality and telemetry suites, since you scoped those out explicitly — flagging that I checked them rather than missed them.

[P1] the operator mitigation — the freehand p.write_text(...) is gone. The section now offers the dashboard route (DELETE /api/schedules/daily-insight, src/dashboard.py:983) and a headless form that loads src/dashboard_schedules.py and calls ds.delete_schedule(path, "daily-insight") — the locked read-modify-write path CLAUDE.md requires for crons.json. The section also records why the earlier revision was wrong, so the next reader does not reintroduce it.

Diff since your review is 1 commit, 3 files, +5/-5 — no production code changed, so the removal you already read is unchanged.

APPROVE at exact head a81f2501e4828ac5811f0fd35d10a377997ec624.

The update clears both blockers from my prior review. The operator procedure now uses the canonical locked dashboard_schedules.delete_schedule writer rather than a direct Path.write_text, and the remaining live references in TELEMETRY.md, the telemetry schema, and the telemetry hook were removed. The focused skill-usage telemetry suite passes 8/8; git diff --check and repository review checks pass.

APPROVE at exact head adfb97cb. This is a merge-only refresh whose first parent is the previously approved topic head a81f2501 and whose second parent is current main. The cumulative 19-file removal diff preserves the canonical locked dashboard_schedules.delete_schedule operator remedy and contains no revived daily-insight references. Focused skill-usage telemetry (8/8), morning-briefing completion/wiring tests, git diff --check, and repository review checks pass. No new blocking finding; worst-case stale per-host schedules remains mitigated by the documented canonical deletion path.

[john-the-dev]

Re-approving at head adfb97cb. My prior APPROVED was carried onto this merge commit by an update-branch, so commit_id == head while submitted_at predates it — the API cannot say which tree I read, and I would rather re-read than let an ambiguous stamp count toward the gate.

Confirming your migration note is load-bearing, not precautionary. You wrote "if your host schedules it". This host does:

hosts/Ruis-MacBook-Pro-2/crons.json:16  "name": "daily-insight",
hosts/Ruis-MacBook-Pro-2/crons.json:19  "prompt": "Run python3 src/daily-insight.py to generate today's behavioral insight..."

Control: pending-questions also returns 2 hits in the same file, so the grep discriminates and the zero you measured on your host is a real host difference rather than a broken search. No launchd plist references it here (0).

So the removal is correct and at least one live host will emit a daily task that can only fail until the entry is removed. That is exactly the population an in-repo grep cannot see, and your body is the only reason a merger would know to look. I will apply your recipe here once this lands.

The rest checks out: src/daily-insight.py is a true deleted file mode, not a stub; crons.example.json drops the entry; 56/56 green; +16/-2057 across 19 files with the test files going out alongside the code they covered.

One thing I want to credit rather than criticise. Your body carries "Nothing invoked it — ON THIS HOST. Corrected 2026-08-26" and separately declines to edit skills/schedule-crons/SKILL.md:208 because it records a dated incident: "Editing a historical record to erase a since-deleted job would falsify it." Both are the right call, and the first is the kind of scope correction that usually gets quietly rewritten instead of marked.

Re-reviewed exact head 7a94ebdf after the merge from main. The PR-owned patch is byte-for-byte equivalent to the previously reviewed head (git patch-id --stable matches), and the merge introduces no conflict resolution changes to the removal. The three affected morning-briefing suites pass locally (19 checks total), with repository review checks and diff hygiene clean. The documented host-cron migration remains required for hosts that still schedule daily-insight, but the code removal itself is ready.

APPROVE at exact head 7a94ebdf9edda637b1d296c27c2919afdf58ed9d.

This is a merge-from-main refresh over the previously approved adfb97cb. Comparing each merge head against its own main parent leaves the same functional 19-file removal topic; the only patch movement is current-main context in generated/source-map documentation. No daily-insight code, schedule example, telemetry registration, or live documentation is revived, and the canonical locked dashboard_schedules.delete_schedule operator remedy remains.

Focused verification passes: skill-usage telemetry 8/8, morning-briefing completion 6/6, src-dir wiring 4/4, and calendar-unavailable 9/9. Repository review checks and git diff --check pass. Worst-case stale per-host schedules remains mitigated by the documented canonical locked deletion path.

The code is ready; merge only after current-head required CI/CLA and the repository approval gate are green.
